It was developed collaboratively by City staff, Carollo Engineers, Inc. (Carollo), and Pacific Groundwater Group. This Plan documents the current status of the water system and evaluates future needs of the water utility. The data used for this Plan was current as of December 2017. The Plan was developed between 2018 and 2020 for approval in 2021. This Plan will be used as a guide in maintaining and improving the water system in the short-term over the next 10 years and also provides a planning framework for the 20-year, long-term planning horizon. The purpose of this Plan is to document changes to the City’s water system, identify required system modifications, and appropriately outline capital improvement projects to meet future water demands. Maintaining a current Plan is required to meet the regulations of the Washington State Department of Health (DOH) and the requirements of the Washington State Growth Management Act. This Plan complies with the requirements of DOH as set forth in the Washington Administrative Code (WAC) 246-290-100, Water System Plan. This Plan contains timeframes, which are the intended framework for future funding decisions and within which future actions and decisions are intended to occur. However, these timeframes are estimates, and depending on factors involved in the processing of applications and project work, and availability of funding, the timing may change. The framework presented in this Plan does not represent actual commitments by the City. Key points of the Plan including analysis results and recommendations are emphasized below, with more detail provided in the chapters. ES.2 Existing Water System The City owns and operates a multi-source municipal water system, which includes supply, treatment, storage, and distribution of potable water to residential, commercial, industrial, and wholesale customers. Service is provided to an area of approximately 17.25 square miles with 17,830 retail customers (service connections) and one wholesale customer, Skyway Water and Sewer District (Skyway), via a single metered connection. The City’s service area boundaries are shown on Figure ES.1. The retail service area (RSA) is the area that the City has a duty to serve within the 20-year planning horizon of this Plan. Figure ES.2 presents the water facility locations. Water supply sources include five production wells (Downtown Wellfield) and one artesian spring (Springbrook Springs) that are used for primary supply. There are also three production wells (Maplewood Wellfield) that provide an alternate source of supply.

Olivet Booster Pump Station Rolling Hills 590 Reservoir The geography of the City requires the water system to have 16 distinct pressure zones (PZs). Figure ES.3 is a hydraulic profile of the system and shows how water moves from one zone to another. The zones are hydraulically interrelated by booster pump stations (BPSs) and pressure reducing valves (PRVs) that are located throughout the City. The Downtown Wells and Springbrook Springs supply water to the lowest pressure zone (Valley 196 PZ) and then the water is pumped up to the surrounding hills (West Hill, Highlands, Renton Hill, Talbot Hill, and Rolling Hills PZs). Water from the Maplewood Wells is pumped from a post-treatment clearwell into the Highlands and Rolling Hills PZs. Two pump stations, one pressure reducing station, and one metered connection can supply water to the Rolling Hills and Talbot Hill PZs from interties with the Seattle Public Utilities (SPU) Cedar River and Bow Lake transmission pipelines. Interties with the SPU Bow Lake transmission pipeline can also supply water to the Earlington 370 and Valley 196 PZs. Currently, there are 10 reservoirs in the system, strategically located to provide adequate equalizing and fire flow reserves for all pressure zones. PRVs are used to supply lower pressure zones from higher pressure zones that contain water storage reservoirs. ES.3 Demand Development Projecting future water demand is a key part of the water system planning process. Demand projections are used to identify the system improvements required for supply, pumping, storage, and piping infrastructure. Three future water demand scenarios (Low, Medium, and High) were projected for the City using the following information: • Historical production and consumption trends from 2008 to 2017. • Puget Sound Regional Council (PSRC) demographic projections. • Future predictions of the impacts placed on demands by factors such as water use efficiency (WUE), climate change, and the expected future consumption of the City’s largest water consumers. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | EXECUTIVE SUMMARY ES-8 | MAY 2021 | FINAL The Medium scenario's predictions most closely resemble the City’s future demands, while the Low and High demand projection scenarios provide a range that the City’s future water demands are expected to fall within. The High and Medium scenarios were used in the Chapter 6 supply analysis, which describes when the City must supplement its own supply with wholesale water purchased from SPU. The Medium scenario was used for the Chapter 7 system analysis, which determines future pumping, storage, and distribution system requirements. Between 2008 and 2017, the City’s average day demand (ADD) was approximately 7 million gallons per day (mgd). During that time, historical maximum day demands (MDD) were approximately 13 mgd. The City’s typical Single-Family household consumes 159 gallons per day (gpd). For demographic trends, PSRC predicts approximately 1 percent annual growth in the number of City households and 1.9 percent annual growth in the number of employees over the 20-year planning period. The same projections for each pressure zone were used to also predict the number of future water connections in the system. For this analysis, water demand projections were developed in the following steps: 1. Increase historical water connection numbers for each pressure zone by the zone-specific residential and non-residential growth rates from the demographic analysis. 2. Convert connection projections into equivalent residential unit (ERU) projections using the historical ERUs per connection. 3. Convert ERU projections to ADD projections using demand projection parameters derived from historical data of the City's starting ERU value, distribution system leakage (DSL), Other Authorized Use, climate change impact, and Largest Consumer demand. City staff established unique demand projection parameters for Low, Medium, and High demand scenarios. 4. Apply the MDD to ADD peaking factor to convert ADD to MDD. Again, each demand scenario has a unique peaking factor selected by City staff. Figure ES.4 also summarizes these steps. EXECUTIVE SUMMARY | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | ES-9 Figure ES.4 Demand Projection Methodology CITY OF RENTON | WATER SYSTEM PLAN UPDATE | EXECUTIVE SUMMARY ES-10 | MAY 2021 | FINAL To project the City's future ADD and MDD, several parameters were used: • ERU value. • DSL. • Other authorized use. • Climate change scenario. • Largest Consumer demand. • MDD to ADD peaking factor. For each of the above parameters, the City used historical data to establish Low, Medium, and High values, which were used to develop each of the demand projection scenarios. This information, with the exception of Largest Consumer demands, is summarized in Table ES.1. The Largest Consumer demands that were incorporated into the demand projections are summarized in Table 3.16 of the Plan. The City’s WUE program will also affect future demands. The City’s three measurable WUE goals that were incorporated into the demand projections are presented in the following section, ES.4.2. Table ES.1 Demand Projection Parameters Demand Projection Scenario Low Medium High Value Notes Value Notes Value Notes ERU Value (gpd/ERU) 153 Historical Minimum 160 WUE Goal 173 Historical Max Distribution System Leakage (Percent of Production) 10% WUE Goal 12.5% Historical Average 12.5% Historical Average Other Authorized Use (Percent of Production) 1.3% Historical Average 1.8% Historical Maximum 2.0% Climate Change Scenario None Warm Warmest MDD/ADD Peaking Factor 1.7 Historical Minimum 1.8 Historical Average 2.0 WUE Goal To calculate the ADD projections for each customer category, the ERU projections were multiplied by the ERU values in gpd/ERU unique to each demand projection scenario and customer category. To establish total ADD projections, non-revenue water consumption, including Other Authorized Use and DSL, was added using Low, Medium, and High assumptions. Finally, for each demand projection scenario, MDD projections were established by multiplying ADD projections by the appropriate MDD to ADD peaking factor. Figure ES.5 shows a chart of the system-wide demand projections. Detailed projections can be found in Chapter 3 and Appendix H. The following summarizes the medium scenario projections. The City's ADD is projected to increase from 7.7 mgd in 2019 to 8.9 mgd in 2029 to 9.8 mgd by 2039. By 2039, the MDD is projected to increase to 17.7 mgd. The analysis forecasts water system demands will increase 1.2 percent annually, which equates to a 27-percent increase over the next 20 years. EXECUTIVE SUMMARY | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | ES-11 Figure ES.5 Projected Water Demands CITY OF RENTON | WATER SYSTEM PLAN UPDATE | EXECUTIVE SUMMARY ES-12 | MAY 2021 | FINAL ES.4 Water Use Efficiency and Conservation Plan In 2003, the Washington State Legislature passed the Municipal Water Law (MWL) to address the increasing demand on Washington’s water resources. As part of this law, the state implemented the WUE Rule, which requires all municipal water suppliers to use water more efficiently in exchange for guaranteed, flexible water rights to help meet future demands. The City started a WUE program in 2007 to emphasize the importance of measuring water use and evaluating the rule's effectiveness. The intent was to minimize water withdrawals and use by implementing water-saving activities and adopting applicable policies, resolutions, ordinances, or bylaws. While Table ES.2 summarizes the mandatory WUE measures, the City conducts many other conservation efforts as listed in Chapter 4. Table ES.2 WUE Mandatory Measures Must implement the following WUE measures: Status Install production (source) meters Implemented Install consumption (service) meters Implemented Perform meter calibration Implemented / ongoing Implement a WLCAP to control leakage if exceeds 10% Implemented / ongoing Educate customers about water efficiency at least once per year Implemented /ongoing Must evaluate or implement these WUE measures: Evaluate rates that encourage water demand efficiency Implemented Evaluate reclamation Implemented Note: Abbreviation: WLCAP – Water Loss Control Action Plan. The City’s current conservation program was developed through a public process to support the City’s WUE goals. The original objectives and goals are being carried forward to this Plan with the goal of encouraging residents to actively and instinctively conserve water. ES.4.1 WUE Objectives As part of the initial WUE compliance, the City reviewed its water system and water usage and developed four objectives for its WUE plan: 1. Identify and reduce sources of DSL. 2. Ensure efficient water supply for continued growth in the service area. 3. Reduce peak day and peak season demands. 4. Maintain the historically low levels of customer water usage. ES.4.2 WUE Goals The City has defined the following measurable goals: 1. Reduce DSL to 10 percent or less by 2022. 2. Limit the MDD to ADD peaking factor to less than 2.0. 3. Maintain an ERU value under 160 gpd/ERU. EXECUTIVE SUMMARY | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | ES-13 As part of the Saving Water Partnership (SWP), the City also supports the regional 2019-2028 WUE goal to keep the total average annual retail water use of SWP members under 110 mgd through 2028 despite forecasted population growth by reducing per capita water use. Based on the number of the City’s connections, the WUE Rule requires the City to also evaluate or implement at least nine measures of its choice that support the proposed goals, in addition to the mandatory measures described above. The selected measures, described below, are conducted either by the City or by the SWP, on behalf of the City: • Water Bill Consumption History. • School Outreach. • Utility Bill Inserts. • Natural Yard Care Workshops. • Advertising and Public Outreach. • City Demonstration Garden. • Indoor Water Conservation Giveaways. • Hose Gaskets. • Water Conservation Education Web Page. The City’s conservation strategy has been to focus on the residential consumer, for both indoor and outdoor consumption, a strategy that has proved successful by continued savings. Most recently, emphasis has been on reducing summer peak usage, which is now a WUE goal. To lower peak consumption, the City has instituted a third billing tier and has increased irrigation rates. ES.5 Policies and Criteria The City’s Plan is based upon the following mission statement for all City utilities: “The City strives to protect the environment and empowers its citizens to be engaged in sustainability programs. The City manages its water system in a manner that ensures public health and safety, meets all regulatory requirements, and protects environmental resources.” (Source: Renton Results – A Community Accountability Program) The City is committed to providing customers high-quality drinking water that is reliable, affordable, and meets strict safety standards. We strive to serve as responsible community stewards by upholding the City’s 2021-2026 Business Plan mission to provide a safe, healthy, and vibrant community by maintaining clean and sustainable drinking water services. The Plan includes policies, effective practices, and goals over time to improve the operation and management of the City’s water supply sources and water system toward sustainability, at a pace consistent with the current and future needs of the community. These goals have been applied to the planning process of the Water System Plan Update and will continued to be implemented in current and future programs and capital projects identified in the Plan. The policies, design criteria, and standards used in the Plan are based on laws and policies that originate from the following sources, listed in descending order, from those with the broadest authority to those with the narrowest: • Federal Regulations - Environmental Protection Agency (USEPA). CITY OF RENTON | WATER SYSTEM PLAN UPDATE | EXECUTIVE SUMMARY ES-14 | MAY 2021 | FINAL • State Regulations - Department of Health and Department of Ecology (DOE). • King County Regulations. • City of Renton Ordinances - City Council. • City of Renton Administrative Policies - Mayor. • City of Renton Comprehensive Plan. • Department Policies - Public Works Department. • Water System Plan Utility Policies - Utility Systems Division/ Water Utility Staff. Law is set by the federal government through federal regulations, by the State of Washington (State) in the form of statutes: Revised Codes of Washington (RCW) and WAC, by King County in the form of policies, and by Renton City Council in the form of ordinances and resolutions. City policies are established in order to provide a vision or mission of the Water Utility and to provide a framework for the planning, design, operation, management, and maintenance of the water system. City policies cannot be less stringent or in conflict with adopted laws. The City manages its water utility and water system in accordance with established federal and state regulations for public water systems. City policies and standards provide a consistent framework for the planning, design, construction, maintenance, operation, and service of the City’s water system and water supply sources. The City has additional land use, development, and finance policies that specify additional requirements for new development or redevelopment projects that require water service for domestic, fire protection, and other uses. The City’s policies are grouped into the following major categories: • Service Area. • Water Supply Planning and Management. • Water Main Extension and Service Ownership. • System Reliability and Emergency Management Plan. • Fire Protection. • Financial. • Facilities. • Organization. ES.6 Water Supply, Water Rights, and Water Quality To meet water demands, the City has developed its own independent water supply sources as well as designed interties with adjacent purveyors to purchase wholesale water. The City’s wells are generally in very good condition. The City has capital improvement and maintenance programs to upgrade and maintain its sources in good condition and to comply with water quality criteria. ES.6.1 Water Rights Independent water sources allow the City to maintain greater control over the management and costs of its water supply. Consistent with DOE's requirements for water rights, all of the City’s water rights specify an instantaneous flow (Qi) and a maximum system-wide annual withdrawal (Qa). With its independent sources of supply, the City strives to protect public health, ensure adequate water supply to meet the requirements of its customers, and support the economic prosperity of the City. However, concern that growing water demands in the future EXECUTIVE SUMMARY | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | ES-15 may exceed the City’s available water right withdrawals must be taken into consideration for system planning. ES.6.2 Water Supply Evaluation The City’s supplies and pump stations were evaluated to ensure adequate capacity is available to serve future demands. For the evaluation, the City’s water distribution system was divided such that the 16 pressure zones were condensed into 7 different operational areas, as shown on Figure ES.3. The City’s criteria is to provide sufficient reliable sources / pumps that can provide the MDD for each operational area with the largest pump or source out of service. The analysis found that each of the operational areas had sufficient source / pumping capacity to meet the projected demands through 2039. The City has sufficient supply to serve its customers with solely its own supplies, with the exception of the West Hill 495 Operational Area. The City needs to rely on its interties with SPU in the West Hill 495 Operational area to provide the MDD demands in the planning period. The City has more than sufficient supplies to meet the system-wide MDD through 2039, as shown in Table ES.4. The City-owned supplies are sufficient to meet the system-wide MDD through 2029, with a small amount of SPU supply required by 2039.

Abbreviation: gpm – gallons per minute. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | EXECUTIVE SUMMARY ES-16 | MAY 2021 | FINAL The City will pursue several different approaches to supplement its peak demand requirements (20-year and longer planning period). This includes expanded conservation efforts and strategies, additional storage, the purchase of wholesale water from SPU, perfecting additional Qi water rights (Maplewood Wells), and the possible use of other technologies such as reclaimed water and aquifer recharge. The City actively participates with other water systems on regional planning, supply, and operating issues. For example, the City is a member of the East King County Regional Water Association and the Water Conservation Coalition of Puget Sound. Another example is the City’s participation in the recent Puget Sound Regional Water Supply Outlook Study, which assessed the supply sources of the Central Puget Sound Region, explored ways that systems can support each other, and evaluated regional supply options to meet future needs. Under the City’s new contract with SPU, the City will be participating in the Seattle Regional Supply System (SRSS) via its attendance and participation at SRSS Operating Board meetings. ES.6.3 Water Quality The City is defined as a Group A Community Public Water System. The City must comply with the drinking water standards of the federal Safe Drinking Water Act (SDWA) and DOH standards under WAC 246-290. The City’s water quality is in compliance with all state and federal water quality and reporting requirements. All applicable drinking water quality regulations are described in detail in the Drinking Water Quality Monitoring Plan included as Appendix N. The City maintains water quality within its system through the following approaches: 1. Routine system flushing within its distribution system in order to maintain satisfactory water quality. 2. A main replacement program to eliminate dead end mains and replace aging cast iron, asbestos cement, and steel pipes. 3. In-line chlorine and fluoride analyzers at all sources for continuous monitoring. 4. In-line pH meters at all sources in order to better manage pH and as a result reduce corrosion within the distribution system. 5. Cross-connection prevention. It is recommended that the City take the following actions as part of its water quality programs: • The City should continue to track proposed new water quality regulations being considered by the USEPA and DOH in order to plan for any impacts on its water system. • The City should continue to implement its corrosion control treatment to minimize corrosion within the distribution system and private plumbing. The City prepares an annual Water Quality Report (CCR) that documents regulated contaminants detected during monitoring to ensure consumers know what’s in their drinking water. The City’s Water Quality Monitoring Reports are electronically available at: https://rentonwa.gov/city_hall/public_works/utility_systems/water_quality_report ES.6.4 Wellhead Protection Program The 1986 amendments to the federal SDWA mandated that every state develop a wellhead protection program (WHPP) to protect groundwaters that serve as drinking water sources for public water supplies. In 1994 DOH adopted WAC 246-290, which directed Group A public water systems using wells or springs to implement wellhead protection measures. The City prepared its EXECUTIVE SUMMARY | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | ES-17 WHPP, which was approved by DOH in 1999. Updates to the City’s WHPP were completed under this Plan and the changes to the WHPP are included as Appendix J. Compliance with WHPP requirements is part of a broader City effort referred to as the “Aquifer Protection Program.” The Aquifer Protection Program was established in 1988 when the Council designated Aquifer Protection Areas (APAs) with the intent of safeguarding the City’s supply sources. The APAs that were initially delineated in 1988 were redefined during this WHPP update to be consistent with the capture zones, which were delineated using the City’s Groundwater Model. As part of its Aquifer Protection Program, the City has enacted aquifer protection regulations within the APAs to protect the aquifers used as potable water supply sources from contamination by hazardous materials. The regulations include restrictions on hazardous material quantities, storage, and handling; land use restrictions; facility operating standards; construction activity standards; fill quality standards; and other measures intended to prevent contamination. Other components of the Aquifer Protection Program include public education, aquifer water quality and level monitoring, coordination with emergency responders, and coordination with surrounding land use authorities on groundwater protection issues. ES.7 System Analysis The system analysis identified potential future system deficiencies in the City’s water distribution and based on the analysis results, Carollo recommended improvements to the system. Carollo evaluated the capacity of the pipelines using the City’s updated and calibrated hydraulic model. Evaluations of the remaining assets were conducted in Microsoft Excel. The system analysis yielded a number of recommended improvements for the pump stations, reservoirs, pipelines, and pressure zones, which are summarized in Figures ES.6 and ES.7. ES.7.1 Storage Analysis The City’s reservoir storage requirements depend on the water system’s configuration, seasonal and daily variation in water-use patterns, and the reliability of various water system components. Water storage volumes are comprised of five components: • Operational storage. • Equalizing storage. • Standby storage. • Fire-suppression storage. • Dead storage. The operational areas were evaluated as separate systems to ensure that each has the required usable operational, equalizing, fire, and standby storage volume. Details are summarized in Chapter 7. Storage deficits were identified in the following operational areas: the Valley, Highlands 565, West Hill 495, and Rolling Hills 590. The identified storage deficits can be mitigated by constructing additional storage or making changes to the operational strategy. In some cases, small improvements to the existing infrastructure, such as adding backup power to provide reliability, can better alleviate the storage deficiencies than adding storage. All recommended projects are summarized below. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | EXECUTIVE SUMMARY ES-18 | MAY 2021 | FINAL Valley Storage Recommendation Although the Valley has sufficient storage at 20 pounds per square inch (psi), the area is deficient for all planning years in supplying operational and equalizing volumes at 30 psi to the customers located at the highest elevations within the operational area. The City is connecting high-elevation residents within the Valley 196 PZ to higher pressure infrastructure. These improvements will then provide adequate operating pressures and fire flow pressures to these high-elevation residents. Highlands 565 Storage Recommendation The Highlands 565 Operational Area does not have sufficient storage for all planning years. However, excess storage located in the adjacent Highlands 445 Operational Area is sufficient to offset deficiencies in the Highlands 565 Operational Area. A backup power generator is recommended at the Monroe Avenue BPS to allow storage to be provided from the Highlands 445 PZ to the Highlands 565 PZ, which will also improve pumping capacity in the long term. The City is already planning to add a generator at the Monroe BPS as part of constructing a new 6.3-million gallon (MG) reservoir in the Highlands 445 PZ. West Hill 495 Storage Recommendation The West Hill 495 Operational Area does not have sufficient storage through 2039. However, excess storage located in the Valley Operational Area is sufficient to offset deficiencies in the West Hill 495. The Valley Operational Area has 1.04 MG of excess storage available by 2039, which can be reliably pumped to the West Hill 495 Operational Area via the new West Hill BPS. The City is currently planning on expanding capacity of the West Hill PS and adding a generator at the West Hill BPS as part of the West Hill BPS Improvement Project. Additionally, the City currently operates the tank with a 16 foot (ft) operational band, which equates to a 0.22-MG operational storage volume. It is recommended that the City update operational strategy and reduce the operational band thus decreasing the operational volume and mitigating deficiencies.

The City has a few options to mitigate this deficiency: • Add backup power to the Maplewood BPS to increase pumping capacity from the Rolling Hills 490 PZ to the Rolling Hills 590 PZ, and add auto-start, auto-transfer, and backup power to the Rolling Hills BPS so that three pumps can be operated at the same time. • Construct a new 1.5-MG standpipe for the Rolling Hills 590 Operational Area, replacing the existing 0.3-MG elevated tank. ES.7.2 Distribution System Analysis The calibrated InfoWater model of the City’s distribution system was used to analyze the system for future planning years, and projected system demands were added for the 2019, 2029, and 2039 planning years. The hydraulic model was used to evaluate typical system conditions during diurnal operations and fire flow availability. Then, the model was updated and calibrated for both extended period simulation with temporary pressure loggers and steady state with hydrant flow tests. Key parameters evaluated with the model were for the system pressure criteria during normal operations and fire flow testing of the system. During normal operations, the minimum pressure as set by the DOH during MDD and PHD was 30 psi at the service meter. The City’s goal is to provide a maximum of 110 psi at the service meter. Improvements include actions such as pipe upsizing, main looping, and modifying pressure zone boundaries. Each of the recommended improvements requires a further site-specific and project-level engineering analysis before implementation. Recommendations are summarized below by type of improvement. Projects to Address Low Peak-Hour Pressure Some low-pressure nodes (below 30 psi) exist adjacent to the Springbrook transmission line. The City has been working to remove connections to this line and relocate them onto an adjacent higher-pressure line. Projects to Address Excessive Velocity One 8-inch line located at the Maple Valley Highway on-ramp to Interstate 405 was found to exceed maximum velocity in the distribution system. This section of pipe is surrounded by 12-inch pipes and is recommended to also be upsized to 12-inch. Project D-13 will upsize 70 ft of 8-inch pipe to 12-inch pipe. Improvements to Address Fire Flow in Non-Dead-End Areas Deficiencies identified during the system analysis require improvements to address fire flow deficiencies. The projects include upsizing 4-inch and 6-inch pipes and changing hydrant lateral connections. Detailed information on each recommended pipe improvement can be found in Chapter 7, where individual projects may be referenced based on Project Identification. Once implemented, these projects will eliminate the identified deficiencies. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | EXECUTIVE SUMMARY ES-24 | MAY 2021 | FINAL Dead-end Pipes in Non-Single Family Areas The City has multiple older 4-inch, 6-inch, or 8-inch dead-end pipes in non-single family areas that do not have the capacity to provide the City’s fire flow requirements of 3,000 gpm. It is recommended that the City evaluate each case individually to determine how fire flows can be provided to each customer. In some cases, a customer may be protected by multiple hydrants on different water mains. As long as the total fire flow from the multiple hydrants meets the fire flow requirement, no improvements are necessary in these cases. In other cases where only one water main serves the customer, looping may be required or the dead-end main may need to be upsized to 12-inch to meet the fire flow requirements. Dead-End Pipes in Single Family Areas The City also has multiple older 4-inch and 6-inch dead-end pipes in single family areas that do not have the capacity to provide the City’s fire flow requirements of 1,000 gpm. It is recommended that the City evaluate each case individually to determine how fire flows can best be provided to each customer. The City has been programmatically moving hydrants from the dead-end to the closest main with 1,000 gpm. It is recommended that the City continue with this approach. ES.7.3 Pipeline Condition Evaluation The pipe condition evaluation incorporates two types of data: remaining useful life (RUL) and maintenance-identified projects. The RUL analysis examined the pipe’s material, installation year, and material’s useful life to determine the year in which each pipe would reach its RUL. The pipes identified in this analysis serve as a starting point for the pipeline condition evaluation. Additional pipeline condition projects have been identified by the City’s Maintenance Department based on field observation and excessive maintenance. These projects, in addition to the RUL analysis projects, make up the pipeline condition evaluation. The length of time that a pipe is anticipated to remain functional is called useful life. Useful life depends largely on the pipe material but can also depend on soil conditions, water constituents, and methods of installation. When a pipe is in service beyond its useful life, the increasing costs of maintenance associated with a failing pipe typically warrant replacement. Figure ES.8 shows the total length of pipe reaching the end of its assumed useful life for each year for the next 100 years, starting in 2019. All pipes that have already exceeded their useful life are shown in the year 2019. EXECUTIVE SUMMARY | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | ES-25 Figure ES.8 Pipes Reaching End of Useful Life CITY OF RENTON | WATER SYSTEM PLAN UPDATE | EXECUTIVE SUMMARY ES-26 | MAY 2021 | FINAL ES.8 Operations and Maintenance The Water Maintenance Services Division maintains and operates the City’s public water infrastructure. Normal, day-to-day operational monitoring including daily water quality checks ensure the integrity of the drinking water provided to customers. Other operations and maintenance (O&M) responsibilities and tasks include: • Preventive Maintenance. • Water Quality Monitoring. • Emergency Response. • Cross Connection Control. • Capital Improvement Planning. • O&M Budget Formulation. • Response to Complaints. Chapter 8 also reviews the water system’s routine operation practices conducted by staff, performance evaluation, operations under abnormal conditions, and preventative maintenance program that manages the condition and operations of all the Water Utility’s major assets. ES.9 Capital Improvement Plan The various projects recommended in the Plan were summarized in a comprehensive Capital Improvement Plan (CIP). With this CIP, the City will have a guideline to plan and budget for the water system over the next 20 years, as well as the recommended timing and cost estimates for each identified project. Project phasing is described as either short term (0 to 10 years, which corresponds to 2020-2029) or long term (10 to 20 years, which corresponds to 2030-2039). The Plan’s capital projects are categorized by the following infrastructure: • Distribution pipeline (D). • Pressure Zone (PZ). • Storage Facilities (ST). • Annual Repair and Replacement (R&R) Programs (P). • Pump Station (PS). • General and On-Going Capital Projects and Programs (G). • Regulatory Compliance Programs (R). As part of the planning and development of the capital improvement plan, the water utility will continue to consider programs and projects to support the City’s business plan, vision and mission for economic growth, social equity, and environmental sustainability goals. The water utility will continue to implement capital improvement projects in a transparent manner, informed by system and community needs and the financial, environmental, and social costs and benefits, to provide long-term community value. The City’s Water Main Replacement Annual Program (WM) consist of the replacement of aging and undersized water mains throughout the water distribution and transmission system. The prioritization and selection of pipes are based on several factors including degree of fire flow deficiencies identified from the hydraulic model, frequency of leaks and breaks, remaining useful life of the pipes, and coordination with other City capital projects. This program reduces the likelihood of system failures, unplanned service interruptions, and claims for damages against EXECUTIVE SUMMARY | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | ES-27 the City. The following project categories identified in this Plan will be ultimately included in the City’s WM Program: • Distribution Pipeline Projects (D), which consist of sited specific projects to help mitigate deficiencies identified in Chapter 7, and sited maintenance main projects. • Annual R&R Programs (P), which included non-sited pipelines. The City will prioritize every year based on the City’s priorities and opportunities such as major roadways improvements and redevelopment areas. Storage projects include construction of the new Kennydale and Highlands 445 reservoirs, and the recommendation of replacing the Rolling Hills 590 and Mt. Olivet reservoirs and a new Blackriver reservoir in the Valley 196 PZ. Pump station projects include improvements at the West Hill BPS, South Talbot BPS, Monroe BPS, and Mt. Olivet BPS. Meanwhile, general projects (G) include studies and seismic-related projects for the distribution system, and on-going capital projects and programs, such as security improvements, or PRV rehabilitation. Finally, regulatory (R) projects represent general water quality compliance projects, water system plan updates, and the water conservation program. Tables ES.4 and ES.5 summarize the CIP projects by project category and priority, respectively. Figures ES.9 and ES.10 summarize the percent of each project identified by project category and project phasing, respectively. Specific project details are provided at the end of the chapter in Chapter 9. When considering CIP costs by project category as shown in Table ES.5 and Figure ES.9, the majority of CIP costs (47.3 percent) are accrued from programmatic projects. Distribution pipeline projects and general projects comprise the other high-cost categories and account for 17.3 percent and 10.4 percent of the CIP, respectively. When considering CIP costs by priority as shown in Table ES.6 and Figure ES.10, approximately 63 percent of the CIP costs are annual programs. The total water CIP cost over the next 20 years is approximately $124 million, which equates to approximately $6 million per year for the planning period. Of the total cost, approximately $28 million is budgeted for the short term, approximately $18 million is budgeted for the long term, and approximately $79 million is budgeted for the annual category.

The financial sufficiency evaluation developed for this Plan aims to determine whether existing and adopted rates are sufficient to cover the capital program developed as a part of Master Plan and, if not, the level of rate increases that would be required to do so. The evaluation relies on a revenue requirements analysis, which is used to test revenue sufficiency against expected revenue needs. There are two tests used to define the annual revenues necessary to provide both sufficient (1) cash flow, and (2) debt coverage. These sufficiency tests are commonly used to determine the amount of annual revenue that must be generated from an agency’s rates: • Cash Flow Sufficiency Test defines the amount of annual revenue that a utility must generate in order to meet annual expenditure obligations. In the same lieu, the cash-flow test identifies projected cash requirements in each year. Cash requirements include O&M expenses, debt-service payments, policy-driven additions to working capital, miscellaneous capital outlays, and rate-funded capital expenditures. These expenses are compared to the total annual projected revenues, and shortfalls are used to calculate the needed rate increases. In this analysis, the cash flow test is the driver of the rate increase. • Debt-Coverage Test refers to the collection of revenues to meet all operating expenses, debt service payments, and debt service obligations, such as debt service coverage ratio (DSCR). The debt-coverage test measures an agency’s ability to meet policy-driven revenue obligations. Currently, the City holds three outstanding debt obligations and does not have any plans to issue additional debt to fund capital projects in the near future. Typical DSCRs range from 1.10x to 1.35x depending on an agency’s financial situation and the type of debt being issued. For this analysis, the debt coverage test was set to meet a 1.25x DSCR based on the City’s outstanding bond’s requirements, meaning that the City must collect sufficient revenue through user rates to meet all on-going O&M expenses, as well as 1.25 times the total debt-service requirements due each year. The debt coverage test was sufficient in this analysis. Financial projections from calendar year (CY) 2020 through CY 2029 were developed using the assumptions and inputs described in Chapter 10, as well as other inputs provided by the City or developed for the project. All three scenarios used the same assumptions for O&M costs, capital expenditures, and most offsetting revenues (all except interest earnings). The financial forecast gives the City a snapshot of its current financial status. As numerous assumptions were made for analysis, projected results can vary from the actual data depending on factors such as actual customer use, demand projection, and growth. Therefore, this high-level projection should be later compared with actuals and adjusted accordingly. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | EXECUTIVE SUMMARY ES-40 | MAY 2021 | FINAL Three funding strategy scenarios were developed to evaluate the 10-year CIP’s impact on the Water Utility’s financial status. Each scenario assumes a different amount of debt to fund the CIP projects. All scenarios include the expected debt issuance with the financing assumptions mentioned above: • Scenario 1, PAYGO (No Additional Debt): This scenario assumes that all 10-year CIP projects are funded by Pay-As-You-Go (PAYGO), using revenues from user rates and available reserves. The City has indicated that this is the preferred scenario as it hopes to no longer rely on debt as a means of controlling long-term expenses. • Scenario 2, Maximized Additional Debt: This scenario maximizes the use of debt to mitigate rate increases in the short term. The first additional debt issuance would be needed in CY 2022 with debt proceeds needed every 3 years of the analysis. • Scenario 3, Moderate Additional Debt: This scenario assumes that rate increases are front loaded in the first 5 years of the analysis, then additional debt issuances are used to smooth out peaks in CIP spending. The first additional debt issuance would be required in CY 2021 and another in CY 2025. The Water Utility has indicated that Scenarios 1 or 3 are the preferred scenarios as they would decrease reliance on debt. Results for each scenario are summarized below: Figure ES.15 compares each scenario’s total capital funding sources from CY 2020 to CY 2029. As shown, Scenario 2 would require substantial use of debt to hold rate increases to 2 percent per year through CY 2025 and still implement the full 10-year CIP. Figure ES.15 Capital Funding Comparison Figure ES.16 compares the outstanding debt principal and projected interest payments that the water funds would hold after CY 2029 for each scenario. Under Scenario 2, the City would still need to pay off approximately $21.90 million in debt principal with almost $11 million in interest payments. This will lead to higher long-term costs and rate increases beyond CY 2029 as compared to what is demanded by the other scenarios. Furthermore, the City may not be able to issue debt at the frequency required for Scenario 2. EXECUTIVE SUMMARY | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | ES-41 Figure ES.16 Comparison of Outstanding Debt After CY 2029 Figure ES.17 compares estimated single family residential (SFR) bills from CY 2020 to CY 2029 under each scenario. As shown, the long-term rate outlook for each scenario has the same general magnitude with estimated single-family charges ranging from about $61 to $68 per month by CY 2029. Increasing the amount of debt issued allows rate increases to be smoothed over time for a more gradual ramp-up to the ultimate rates. Figure ES.17 Estimated Single Family Residential Bill Comparison These projections are intended to guide the financial planning of the City’s Water Utility, not to serve as the basis for any implemented rate increases. As the City works with its rate consultant to complete a comprehensive rate study, more detailed short-term projections should be developed for the rate-study period. CHAPTER 01 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 1-1 Chapter 1 INTRODUCTION 1.1 Purpose This Water System Plan (Plan) updates the City of Renton’s (City) 2012 Water System Plan. It was developed collaboratively by City staff, Carollo Engineers, Inc. (Carollo), and Pacific Groundwater Group. This Plan documents the current status of the water system and evaluates future needs of the water utility. The data used for this Plan was current as of December 2017. The Plan was developed between 2018 and 2020 for approval in 2019. This Plan will be used as a guide in maintaining and improving the water system in the short-term over the next ten years and also provides a planning framework for the 20-year, long-term planning horizon. The purpose of this Plan is to document changes to the City’s water system, identify required system modifications, and appropriately outline capital improvement projects to meet future water demands. Maintaining a current Plan is required to meet the regulations of the Washington State Department of Health (DOH) and the requirements of the Washington State Growth Management Act. This Plan complies with the requirements of DOH as set forth in the Washington Administrative Code (WAC) 246-290-100, Water System Plan. This Plan contains timeframes, which are the intended framework for future funding decisions and within which future actions and decisions are intended to occur. However, these timeframes are estimates, and depending on factors involved in the processing of applications and project work, and availability of funding, the timing may change. The framework presented in this Plan does not represent actual commitments by the City. 1.2 Authorization Recognizing the importance of planning, developing, and financing water system facilities to provide reliable service for the existing customers and to serve anticipated growth, the City initiated the preparation of this Plan. In October 2017, the City selected the Carollo team to assist in the preparation of the updated Plan in accordance with applicable rules and regulations governing planning for water utility systems. 1.3 Objectives This Plan has been prepared to serve as a guide for planning and designing future water system facilities and to assist the City in using its water resources in the most efficient manner possible. Identified in this Plan are system improvements intended to meet the expanding and changing needs of the City. Specific objectives of this Plan are addressed by individual chapters presented herein and include the following: • Develop a document that can be updated periodically as additional information on the water system is obtained. • Description of Existing System (Chapter 2): Document the existing water system supply, storage, and distribution facilities. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 01 1-2 | MAY 2021| FINAL • Planning Data and Water Demand Forecast (Chapter 3): Identify and estimate the effect of future land uses and population trends on the water system. Document historical water use, and project future demands based on growth projections. • Water Conservation Program (Chapter 4): Identify the role that water use efficiency will have in reducing future water requirements and how the City’s water conservation program will be implemented. • Water System Policies, Criteria, and Standards (Chapter 5): Establish clear policies and criteria relating to water service within the City’s water system. • Water Supply and Water Rights (Chapter 6): Document existing and potential future water supply and water rights and discuss existing and forthcoming regulatory requirements on the City water system. • System Analysis (Chapter 7): Update the computerized model for analysis of the system. Assess the capability of the existing water system to meet existing and projected future demands, identify water system deficiencies. • Operations Program (Chapter 8): Provide a comprehensive review of operations and maintenance of system facilities. • Capital Improvement Plan (Chapter 9): Develop a program of capital improvements, including priorities for design and construction. • Financial Program (Chapter 10): Develop a plan for financial backing of required system improvements. • Prepare an environmental checklist for city council action on the proposed water system plan. The checklist is to be reviewed by the various City departments for a threshold determination. • Prepare the Plan to comply with the requirements of the DOH. 1.4 Location The City is located within King County at the southeastern end of Lake Washington. Interstate 405 (I-405) runs through the middle of the retail service area (RSA), from its western boundary, up through its northern boundary. The Cedar River divides the City’s RSA between the north and south. The City’s water system provides service to an area of approximately 17.25 square miles that is largely coincident with the city limits. The water distribution system serves the valley floor and parts of five surrounding hills: West Hill, the Highlands, Scenic Hill (also known as Renton Hill), Talbot Hill, and Rolling Hills. The City currently serves customers within an elevation range of 11 to 476 feet. This range creates a need for at least four separate pressure zones. However, physical barriers such as hills and valleys often prevent the extension of a pressure zone from one location to another. As a result of the City’s topography and geography, the City has 16 hydraulically distinct pressure zones. The City’s RSA is bordered by nine adjacent water systems: the Skyway Water and Sewer District (Skyway), Seattle Public Utilities (SPU), the City of Tukwila, the City of Kent, the Soos Creek Water and Sewer District (Soos Creek), the Cedar River Water and Sewer District (CRWSD), King County Water District No. 90, the Coal Creek Utility District (UD), and the Wasmeta Park Water System. Figure 1.1 shows the City’s neighboring water utilities, as well as the RSA boundary. CHAPTER 01 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 1-3 1.5 Ownership and Management The City’s water system is officially designated in the DOH records as City of Renton, system identification number 71850L. It is a municipal, Class A water system. The City has a city council-mayoral form of government. Members of the council and the mayor are elected officials. The mayor is the head of the executive branch of the government and is the chief executive officer of the City government and as such has general supervision over the several departments of the City and over all its interests. Figure 1.2 shows the organization of the drinking water utility. With the exception of the billing function, the operation of the utility falls under the supervision of the administrator of the Planning/Building/Public Works Department, Mr. Martin Pastucha. Some of the City offices that provide support to the operation of the Drinking Water Utility are not shown on the organizational chart. For example, the Human Resources/Risk Management Department provides hiring, benefits, insurance, some types of training, and other support to the utility; the Information Services Division provides computer, networking and telecommunications support; and the City Attorney’s Office provides legal support. Budgets are formulated by the departments and are presented by the mayor to the city council for approval. Expenditures for items in a council-approved budget are approved by the administrator, the mayor, or the council depending upon the amount of expenditure. The main point of contact for the water system is as follows: Name: George Stahl – Water Maintenance Manager Phone: (425) 430-7400 Email: Gstahl@rentonwa.gov Address: 3555 NE 2nd Street Renton, WA 98056 1.6 System History The City’s municipal water service system was established in 1901. The municipality's source of water was first drawn from Renton Springs which was the primary source for this growing coal mine community but was eventually abandoned. A new source facility was constructed in 1924 at Springbrook Springs at the south end of the City. This artesian spring has since undergone several renovations and reconstruction phases while still providing water by gravity feed. From the early 1940's to the 1990’s, other groundwater sources were developed to augment capacity and to provide water supply reliability. These sources include six “Downtown” wells (RW-1, RW-2, RW-3, PW-8, PW-9, EW-3R) in the shallow Cedar River Delta Aquifer, three “Maplewood” wells (PW-11, PW-12, PW-17) in the deep Maplewood Aquifer, and one emergency well (PW-5A) in the Kennydale area. In 2011, the City signed a 60-year water supply contract with SPU for the purchase of additional supply to meet the City’s future growth demand and for peak demand periods. A detailed history of the City’s system is well documented in Chapter 2 of this Plan and in the previous water system plans prepared for the City by CH2M Hill in 1965, by RH2 Engineering in 1983, 1990, and 1998, by RW Beck in 2006, and by Carollo in 2012. The previous water system plans are available from the City upon request.

The RSA is the area that the City has a duty to serve within the 20-year planning horizon of this Plan. The future service area is currently served by SPU but will likely be served by the City in the future. This area was originally defined in the Skyway Coordinated Water System Plan and is also described in service area agreement between the City and Skyway. The area would only become part of the water service area upon annexation into the City. The City’s service area includes the RSA, the future service area, and the portion of Skyway that is supplied by Renton wholesale water. The City’s RSA boundary and future service area were initially defined by the East King County Coordinated Water System Plan (Agreement CAG-075-89) and its update (CAG-97-100) and by the Skyway Coordinated Water System Plan (CAG-076-89). These boundaries were further refined by agreements with the adjacent water purveyors: Skyway (CAG-03-197), Soos Creek (CAG-91-083 and CAG-97-164), and CRWSD (CAG-99-014). It is unlikely that the City’s RSA will change very much in the future because of the geography of the surrounding areas and the fact that all of the surrounding areas are currently served by other water purveyors. However, the City is considering small revisions to the boundary lines with both Soos Creek and CRWSD to better align with service in developments to City customers. These changes will be coordinated, reviewed, and mutually agreed upon with the adjacent purveyor in the future. Figures 1.4 and 1.5 illustrate these two areas.

CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 2-1 Chapter 2 EXISTING SYSTEM 2.1 System Overview The City of Renton (City) owns and operates a multi-source municipal water system, which includes supply, treatment, storage, and distribution of potable water to residential, commercial, industrial, and wholesale customers. Service is provided to an area of approximately 17.25 square miles with 17,830 retail customers (service connections) and one wholesale customer, Skyway Water and Sewer District, via a single metered connection. The City’s Water Facilities Inventory (WFI) is located in Appendix E. Figure 2.1 presents the water facility locations. Water supply sources include five production wells (RW-1, RW-2, RW-3, PW-8, and PW-9) and one artesian spring (Springbrook Springs) that are used for primary supply. Springbrook Springs is located at the south end of the service area. The wells are located in Liberty Park and Cedar River Park, and pump from a relatively shallow aquifer (Cedar Valley Aquifer). One emergency well (EW-3R) pumps from the same aquifer but is only available as a backup source of supply. These six wells are referred to as the “Downtown Wells”. There are also three production wells (PW-11, PW-12, and PW-17) located east of the downtown area at the Maplewood Golf Course that provide an alternate source of supply in the event of the contamination of the Downtown Wells. A secondary purpose of the Maplewood Wellfield is to provide additional instantaneous flow (Qi) during high demand periods. The permits for the Maplewood Wells set the system-wide annual withdrawal (Qa) to no more than the existing certificated Qa of 14,809.5 acre-feet (i.e., the Maplewood annual water rights are non-additive). The Maplewood wells pump from a deep aquifer (Maplewood Aquifer). A single emergency well (PW-5A) is located at the north end of the service area. Well 4 is currently inactive, as is Well PW-5A which is only used as backup due to water quality issues. These sources authorize total primary water right allocations in the amount of 1,670 gallons per minute (gpm) and 2,593.5 acre-feet per year (ac-ft/yr), which is being exercised through the use of supplemental sources. The City is a wholesale customer of Seattle Public Utilities (SPU). The City has seven metered interties with the SPU transmission mains, which are available to serve wholesale water to the City’s distribution system. The City also has two metered interties with SPU to serve water directly to the Renton Boeing Plant. The City currently only buys wholesale water from SPU to sell to Boeing, but the City has a long-term supply contract for backup supply and future water demands. The City has three emergency supply interties with neighboring water systems. All of the water the City produces comes from a well or spring. Because of this supply configuration, the City’s water system is maintenance-intensive, with facilities for pumping, water quality control, and emergency power generation. Areas within the City’s Retail Service Area (RSA) may have similar elevations but cannot be served as part of the same pressure zone due to the geography. For instance, the pressure zones CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 02 2-2 | MAY 2021| FINAL in the Highlands area have not been extended across Maple Valley into the Renton Scenic Hill or Talbot Hill areas, even though the elevations served on these two hills are similar. The Cedar River Valley provides a physical barrier that has precluded joining hydraulically similar pressure zones. As a result of these physical barriers and the elevation range served, 16 pressure zones are necessary to serve the City’s customers within acceptable pressure ranges. Figure 2.1 illustrates how water moves horizontally through the distribution system. Figure 2.2 is a hydraulic profile of the system and shows how water moves vertically from one pressure zone to another. All of the pressure zones are hydraulically interrelated with the lowest pressure zone located in the valley floor. It is desirable to have two or more connections (or supply points) within each pressure zone to allow water to move upward to a higher-pressure zone or downward to a lower pressure zone. This maximizes system reliability by providing multiple routes to move water between pressure zones. Pumping between pressure zones is accomplished by 12 booster pump stations (BPS) that are located throughout the City. The Downtown Wells and Springbrook Springs supply water to the lowest pressure zone (Valley 196 Pressure Zone [PZ]) and then the water is pumped up to the West Hill, Highlands, Renton Hill, Talbot Hill, and Rolling Hills PZs. Water from the Maplewood Wells is pumped from a post-treatment clearwell into the Highlands and Rolling Hills PZs. Water from Well PW-5A is also pumped into the Highlands 435 PZ. Two pump stations, one pressure reducing station, and one metered connection can supply water to the Rolling Hills and Talbot Hill PZs from interties with the SPU Cedar River and Bow Lake transmission pipelines. Interties with the SPU Bow Lake transmission pipeline can also supply water to the Earlington 370 and Valley 196 PZs. Currently there are 10 reservoirs in the system, strategically located to provide adequate equalizing and fire flow reserves for all pressure zones. Pressure Reducing Valves (PRVs) are used to supply lower pressure zones from higher pressure zones that contain water storage reservoirs. !W(!W( !W( !W( !W(!W(!W(!W(!W( !W( !W( X7 X7 X7 WTP WTP WTP UUT UUT UUT UUT UUT UUT UUTUUT UUT UUTUUT UUT XÚXÚXÚXÚ XÚXÚ XÚXÚ XÚXÚ XÚXÚXÚXÚ XÚXÚXÚXÚ XÚXÚXÚ XÚXÚXÚ XÚXÚXÚ XÚXÚXÚXÚ XÚ XÚXÚXÚ XÚXÚXÚXÚXÚXÚ !5 !5 !5 !5 !5!5 !5 !5 !5!5 !5!5 !5 !5!5 !5 !5 !5 !5!5 !5 !5 !S(!S( "5 "5"5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5"5 "5 "5"5 "5"5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 East Valley RdRainier Ave NS 133rd St Oakesdale Ave SWSW 7th St 140th Ave SEN E S u n set Blvd §¨¦405 Map l e V a l l e y H w y 164th Ave SESE Jones Rd Lake Youngs Service RdSE May Valle y R d Union Ave NESE Petrovitsky Rd Rolling HillsReservoirs 490 (3 MG)and 590 (0.3 MG) Springbrook SpringsInfiltration Galleries Springbrook SpringsTreatment Plant South Talbot Reservoir Kent Intertie TukwilaIntertie Bow LakePipeline SPU Station #33 SPUStation#34 FredNelsonBPS North Talbot BPSNorth TalbotReservoir Tiffany Park BPS RollingHills BPS MaplewoodChlorinationFacilityMaplewoodClearwell MaplewoodBPS PW-12 PW-11PW-17 Mt OlivetReservoir& BPS MonroeAvenue BPS WD 90Intertie HouserWay BPS RW-1,2 & 3 Renton/Seattle IntertiePW-8 PW-9EW-3RBoeing PlantMeter - Eastand West West HillReservoirDimmit BPS SkywayWholesale West Hill BPS Highlands BPS Highlands1.5 & 2.0MG 435Reservoirs Highlands0.75 MG565 Reservoir Hazen Reservoir PW-5A Coal Creek Intertie PW-4 SouthTalbot BPS SPU Station #39 ?æ ?Å ?ç LakeBoren LakeDesire Lake Youngs ShadyLake PantherLake LakeWashington Last Revised: February 08, 2021 \\io-fs-1\Data\GIS\GISBackup\Renton\WaterSystemPlan2017\Fig2.1_WaterSystemLocation_V2.mxd CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON Figure 2.1 Water Facility Locations O 0 3,0001,500 Feet Disclaimer: Features shown in this figure are for planning purposes and represent approximate locations.

A description of each facility and any major changes are summarized in the following sections. 2.2.1 Pressure Zones As described above, the geography of the City requires the water system to have 16 distinct pressure zones. The hydraulic profile shown in Figure 2.2 shows how the pressure zones are interrelated and demonstrates how water can move through the system between pressure zones. All pressure zones are served directly or indirectly from the City’s active wells and Springbrook Springs. The Downtown Wells (RW-1, RW-2, RW-3, PW-8, and PW-9) and Springbrook Springs directly supply the Valley 196 PZ. The Maplewood Wells (PW-11, PW-12, and PW-17) supply the Highlands 565 PZ and Rolling Hills 590 PZ. Although the system has 16 distinct pressure zones, not all of the pressure zones have separate storage or supply facilities. Some pressure zones are supplied exclusively by pressure reducing stations from an upper pressure zone. It is impractical to plan facilities and improvements for all of these pressure zones individually; therefore, the water system has been divided into seven operating areas. Each operating area is either a single pressure zone or a combination of pressure zones with similar operating characteristics. For instance, a lower pressure zone that is supplied exclusively by PRVs from an upper pressure zone would be combined with the upper pressure zone to form an operating area. For the majority of this Plan, the pressure zones are organized into the seven operating areas as indicated in Table 2.1.

CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 2-9 2.2.2 Source of Supply The City produces water from production wells and an artesian spring. Each of the supply sources is described in the sections below. Table 2.2 lists the active supply sources and the rated capacity of each. The table does not include inactive sources or interties. All of the City's interties, regular and emergency supply, are summarized in Table 2.3. 2.2.2.1 Springbrook Springs (Department of Health [DOH] Source S05) Located at the south end of the City, Springbrook Springs is an artesian spring that supplies approximately 15 to 20 percent of the City’s drinking water. Springbrook Springs was first used in 1909. The infiltration galleries were upgraded and a sanitary seal was added to each in 1976 (project number W-0422). Chlorination was added in 1976 (W-0423). The chlorination building is located approximately 300 yards from the infiltration galleries and is adjacent to the transmission main. Fluoridation was added in 1986 (W-0851) via an addition to the chlorination building. Corrosion control treatment was added in 1999 (W-2238) and a sodium hydroxide storage building was constructed as part of this project. The City has ownership of a significant amount of property that forms a watershed directly surrounding Springbrook Springs. A chain link fence was erected around the property to restrict activities and access to the watershed. The last segment of chain link fence was installed in 2002 (W-2980). Springbrook Springs provides direct service to the Valley 196 PZ. In 2010, a motorized valve was added to the treatment facility to stop the flow of water when the chlorine residual drops below a safe level. The power source is a 20-kilowatt (kW) generator (propane fuel source). The generator is auto-start and the transfer from commercial power to electric generator power is automatic. Currently, flow control is via a manually set gate valve (throttling valve). In 2013, a chlorine line was added at Springbrook Springs to provide primary disinfection. The dosing pipeline was installed adjacent to the Transmission Main and taps into the existing main at a manhole (new chlorine injection point). The manhole is about 770 ft upstream of the chlorination building and 1,195 ft upstream of the connection point for first service. This manhole serves as the chlorine injection point such that the minimum required chlorine contact time is achieved before the supply enters the distribution system (W-3648). Concentration of free chlorine times Contact Time (CT) of 11 milligram-minutes per liter (mg-min/L) is achieved for the Springbrook Spring’s supply. A chlorine analyzer was installed as part of Project W-3648, which provides continuous chlorine concentration monitoring.

CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 2-11 2.2.2.2 Wells 1, 2, and 3 (DOH Source S10 – Wellfield) Wells PW-1 and PW-2 were originally drilled in 1942 in Liberty Park adjacent to Houser Way North and the Cedar River. The wells were replaced by Wells RW-1 (DOH Source S01) and RW-2 (DOH Source S02) in 1988 (W-0880). Well PW-3 was originally drilled in 1959 and the wellhead constructed in 1962 (W-0119) in Liberty Park near the intersection of Houser Way North and Bronson Way North. Well RW-3 (DOH Source S03) replaced Well PW-3 (W-0880) but was co-located in the wellhouse with RW-1 and RW-2. Project W-0880 also included both chlorination and fluoridation. Corrosion control treatment was added in 1999 (W-2238). A manual transfer switch with Kirk-Key safety system was added in 1999 to allow the wellhouse to be powered by a City-owned portable generator (W-2784). In 2007, an emergency electrical power generation facility was constructed at the Mt. Olivet Reservoir site to provide backup power for the Mt. Olivet BPS and Wells RW-1, RW-2, and RW-3 (W-3239). A power transmission line was installed from the new power facility to an automatic transfer switch located at the transformer adjacent to the wellhouse. The portable generator and manual transfer switch configuration remains as a secondary backup. The automatic transfer switch, which was originally installed in 1988 (W-0880), was rebuilt in 2010. Primary disinfection was added to the three wells in 2003 using a loop of large diameter pipe (CT Pipe 1) in Liberty Park. The chlorine contact pipeline provides 4-log inactivation of viruses prior to discharge into the distribution system (W-2893). The three sources share a common tap for source water samples, which are collected after treatment but before entry into the distribution system. A continuous chlorine concentration monitoring and control system was installed and integrated with the City’s existing telemetry system as part of Project W-2893. Each well is individually metered and is controlled by the water level elevation in the North Talbot Reservoir. Additionally, in 2010 the backpressure control valves were converted to flow control valves to prevent the flow rate from exceeding the water right Qi. The meters are located inside the wellhouse. The roof of the wellhouse was replaced in 2016.The wells pump into the Valley 196 PZ. 2.2.2.3 Wells 8 and 9 (DOH Source S20 – Wellfield) Well PW-8 (DOH Source S07) was initially drilled in 1968 and the wellhead constructed in 1969 (W-0310). Project W-0310 also included chlorination. Well PW-9 (DOH Source S09) was drilled in 1984 (W-0665) and the wellhead constructed in 1985 (W-0718). Project W-0718 included adding chlorination and stubbing out a 3.5-inch electrical conduit from the main panel to the west side of the building for a future emergency power feed (refer to WTR-13-0035, Emergency Power System Study 1989). The wellhouses are located in Cedar River Park adjacent to Interstate 405. Fluoridation was added in 1986 (W-0851). Corrosion control treatment was added in 1999 (W 2238). The electrical system for Well PW-8 was rehabilitated in 1990 (W-1020). The rehabilitation project included adding an automatic transfer switch and stubbing out a 4-inch electrical conduit from the main panel to the west side of the building for a future emergency power feed (refer to WTR-13-0035, Emergency Power System Study, 1989). Primary disinfection was added in 2013 (W-3582). The project included combining and routing the Well PW-8 discharge line and Well PW-9 discharge line through a loop of large diameter pipe in Cedar River Park to provide 4-log inactivation of viruses prior to discharge into the distribution system. The two sources share a common tap for source water samples, which are collected CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 02 2-12 | MAY 2021| FINAL after treatment but before entry into the distribution system. A chlorine analyzer was installed as part of Project W-3582 to provide continuous chlorine concentration monitoring. Both wells are individually metered and controlled by the water level elevation in the North Talbot Reservoir. Each meter is located in a vault adjacent to the wellhouse. The wells pump water to the Valley 196 PZ. 2.2.2.4 Emergency Well 3R (DOH Source S16) Emergency Well EW-3R was drilled in 1999 (W-2315) and the wellhead constructed in 2003 (W-2915). This well replaced EW-3, which was located at the original Well PW-3 wellhouse in Liberty Park near the intersection of Houser Way North and Bronson Way North. Project W-2315 included chlorination, fluoridation, and treatment for corrosion control. The project also included switchgear and a receptacle to feed power from a portable generator set. Primary disinfection was added to the emergency well in 2013 using a loop of large diameter pipe (CT Pipe 2) installed at the north end of Liberty Park (W-3582). The chlorine contact pipeline provides 4-log inactivation of viruses prior to discharge into the distribution system. This is a metered source and is controlled by the water level elevation in the North Talbot Reservoir. The meter is located inside the wellhouse. The well pumps into the Valley 196 PZ. Well EW-3R 2.2.2.5 Well 5 (DOH Source S04) Well PW-5A was drilled in 1988 (CAG-070-86) and the wellhead constructed in 1991 (W-0888). Well PW-5A is currently inactive due to water quality issues. The wellhouse is located on the northwest corner of Jones Avenue NE and NE 24th Street. Well PW-5A replaced Well PW-5 CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 2-13 (formerly Kennydale Well No. 1), which had severe sanding problems and could not be successfully redeveloped. The original Well PW-5 was drilled in 1953. Project W-0888 included both chlorination and fluoridation as well as the addition of a switchgear and a receptacle to feed power from a portable generator set. Treatment for corrosion control is not necessary, as the pH of the raw water is about 8.0. This source can be used for emergency supply but has taste and odor problems. The raw water, similar to the Maplewood Wellfield, contains hydrogen sulfide, iron, manganese, and ammonia. At some time in the future, additional treatment will be added to address these problems. This is a metered source which is controlled by the water level elevation in the Highlands 435 Reservoirs. The meter is located in a vault, which is approximately 45 ft to the east of the wellhouse. The well pumps into the Highlands 435 PZ. 2.2.2.6 Wells 11, 12, and 17 (DOH Source S13 – Wellfield) Located at the Maplewood Golf Course on Maple Valley Highway, the Maplewood Wellfield consists of three wells: PW-11 (DOH Source S11), PW-12 (DOH Source S15), and PW-17 (DOH Source S12). Wells PW-11 and PW-17 were drilled in 1989 (CAG-88-030) and the wellheads constructed in 1991 (W-0850 and W-1027). Well PW-12 was drilled in 1994 (WTR-13-042) and the wellhead constructed in 1998 (W-2279). Treatment for these wells is provided at the Maplewood Treatment and BPS Facility, which was constructed in 1995 (W-1052). The raw water contains hydrogen sulfide, ammonia, manganese, and a small amount of iron. The original strategy for treating the water was to remove hydrogen sulfide using aeration and to keep the manganese in solution using ortho-polyphosphate (sequestering) as well as chlorinating and fluoridating the water. Treatment for corrosion control is not necessary, as the pH of the raw water is about 8.0. The presence of ammonia was discovered after the plant went online. The sequestering did not work and the water utility received numerous complaints regarding staining, taste, and odor. The method used for secondary disinfection was changed from chlorination to chloramination, which limited the areas in which the water could be used in the distribution system due to problems with mixing the Maplewood water with the chlorine-treated water from the other sources. In January 2002, the City shut the wellfield down and began design and construction efforts to replace the treatment method. A treatment pilot plant study was conducted in June and July of 2001. The resulting design consisted of: 1. Converting hydrogen sulfide to sulfate by adding oxygen from air and reacting on granular activated carbon (GAC) filters. 2. Removing manganese with green sand filters. 3. Converting ammonia to nitrogen gas by adding chlorine and reacting in a contact basin. Construction (W-2953) of a new treatment building began in October 2003 and the treatment plant was put into operation in September 2006. The project included changing the method of chlorination from chlorine gas to sodium hypochlorite liquid. Fluoridation is accomplished by using the existing plant. The project also included a manual switchgear with Kirk-Key safety system to allow powering one 1,500-gpm production well, one 1,550-gpm low-lift pump, and one 1,550-gpm high-lift pump and associated treatment equipment with a City-owned portable generator. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 02 2-14 | MAY 2021| FINAL In 2015, equipment access improvements were made to the Maplewood Water Treatment Plant including installation of access platforms around the GAC contactors and green sand filter vessels. Ventilation improvements were also made to the facility (W-3610). Each well is individually metered. The meters are located in the new treatment building. Flow from each well is kept below the proposed Qi water right by using flow control valves. The wells are controlled by either the elevation in the Highlands 565 Reservoir or the Rolling Hills 590 and 490 Reservoirs (see discussion of Rolling Hills BPS – in particular the back-pressure sustaining valves regulating the flow between the 490 and 590 PZs). The treated water is pumped to the clearwell located at the existing Maplewood Treatment and BPS facility. After at least 3 to 4 hours of contact time, the water is pumped to either the Highlands 565 PZ or the Rolling Hills 590 PZ. 2.2.2.7 Well 4 (DOH Source S06) Well 4 was drilled in 1942 for the Northwest Water Company. The well was removed in 1962. The City has an active water right of 170-gpm for the well (GWC 884-D). Well 4 is currently inactive, as is Well PW-5A which is only used as backup due to water quality issues. 2.2.2.8 Seattle Interties (DOH Source S08) Currently there are 10 interties with SPU. Two of the interties are used to supply water to the Boeing Renton Plant via two 10-inch mains. Prior to 2001, Seattle sold this water directly to Boeing. In 2001, in accordance with a revised franchise agreement between Seattle and Renton, the metering points for the two 10-inch service lines were moved closer to the SPU Cedar River Pipelines (W-2890), and the City began purchasing the water wholesale from Seattle and selling to Boeing. One of the ten interties was originally constructed as a retail supply point for Seattle to provide water to the Longacres Racetrack site. In 1994, the connection was upgraded (W-2071) and is currently used as a backup fire flow supply for the Boeing Longacres site. This is an 8-inch connection to the 60-inch SPU Bow Lake transmission main at PRV Station 24. This intertie was modified in 2010 (W-3553) with a flow control valve so that it can be used to provide wholesale water to the City’s system in the future. Bow Lake intertie is available for summer peaking. Six other interties are currently available for summer peaking supply. These are SPU Station Nos. 33, 34, 36, 37, 38, and 39 and are further described in Table 2.3. Project W-3553 involved upgrading SPU stations 34 and 39 with flow meters and pressure gauges, as well as the Bow Lake Intertie. The remaining intertie is configured for supplying water to the SPU Mercer Island Pipeline. 2.2.2.9 Emergency Supply Sources The City maintains several emergency supply sources: one emergency well, EW-3R, and three emergency interties (PRV #23, PRV #25, and Dimmit BPS). Copies of all of the City's intertie and emergency supply agreements are included in Appendix D.

CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 02 2-16 | MAY 2021| FINAL 2.2.3 Storage Water storage within the distribution system provides for operational, equalizing, firefighting, and standby storage volumes. Storage is provided by reservoirs, standpipes, and elevated tanks located within the distribution system. The City currently maintains and operates ten reservoirs and one operational storage/equalizing/detention clearwell at the Maplewood Treatment and BPS Facility. This section provides a description of the function and condition of each of these facilities. Table 2.4 lists all of the City’s existing storage facilities and summarizes the physical characteristics. The recommended sizing and location of future storage facilities are presented in Chapter 9 - Capital Improvement Plan. 2.2.3.1 Maplewood Clearwell Located at the Maplewood Treatment and BPS facility, this clearwell was constructed in 1995 (W-1052). The treated water from the Maplewood Treatment and BPS facility is pumped to the clearwell. After at least three to four hours of contact time, the water is pumped to either the Highlands 565 PZ or the Rolling Hills 590 PZ. Additional details can be found under Section 2.2.2.6. 2.2.3.2 North Talbot Reservoir (Valley 196 PZ) Located at Talbot Hill Park near the intersection of Talbot Road S and S 19th Street, this 5-million gallon (MG), cast-in-place, reinforced concrete underground reservoir was constructed in 1976 (W-0419). The reservoir replaced two uncovered 0.5-MG reservoirs that occupied the same site. In 1989, CH2M Hill visually inspected the reservoir. Leaching of the concrete was observed, but the joint sealant was in generally good condition. Following the inspection, CH2M Hill recommended that the access ladder and overflow pipe supports be replaced with stainless steel. They also recommended that the City install galvanic cathodic protection anodes to protect metal associated with the intake piping, wash-down piping, and other metals submerged in the reservoir. The interior was visually inspected again in 2010 by Water Utility staff who noted that all steel and iron surfaces were badly corroded and need to be replaced or recoated (WTR-27-0419). Because of the corrosion, the inlet/outlet pipes and 2.5-inch wash down pipes are no longer usable. The floor slab appeared to be in good shape with no exposed rebar and minor pitting near the columns. The columns appeared to be in fair condition with some areas of exposed aggregate and rust staining. The origin of the rust staining was not determined. The roof to column connections appeared to be in good condition. The exterior of the reservoir roof is a tennis court. It has been noted that several depressions exist on the roof and retain rain water during storm events. In 2017, the reservoir was drained and inspected. A leak test was performed and noted that even with missing joint material the reservoir does not leak. Likely this is due to the rubber joint material installed. 2.2.3.3 Mt. Olivet Reservoir (Valley 196 PZ) Located near the intersection of NE 3rd Street and Bronson Way NE, this 3-MG aboveground cylindrical steel reservoir was constructed in 1954 (W-1141). CH2M Hill has periodically inspected CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 2-17 it over the years (1969, 1977, 1982, 1985, 1989, and 1997). In 1971, an impressed-current cathodic protection system was installed (W-0371). The exterior was recoated in 1978 (W-0476). The interior was recoated in 1991 (W-1035). The exterior was recoated and the cathodic protection system replaced in 1999 (W-2787). The exterior was recoated again in 2008 (W-3449) because of the failure of the 1999 coating. The interior was inspected most recently in 2009. The steel stringers between the roof beams are corroded badly and need to be replaced. Norton Corrosion Limited inspected the reservoir’s cathodic protection system in 2017 (WTR-13-0123). They reported that the reservoir had adequate protection based on their testing results. One issue with this tank site is the aerial high voltage lines close to the steel tank. Based on the observations made during the 2009 inspection, the City performed a preliminary design (WTR-13-0104, Water Distribution Storage Planning Study) of replacing the existing reservoir with a 7-MG reservoir. The estimated cost of replacing the reservoir is $8.25 million. 2.2.3.4 Highlands 435 Reservoir – 1.5-MG (Highlands 435 PZ) Located at the Highlands Reservoir site east of the intersection of NE 12th Street and Monroe Avenue NE, this 1.5-MG reservoir was originally constructed as an uncovered reservoir during World War II (circa 1942). The reservoir was concrete-lined, rectangular in shape, partially in-ground and partially aboveground with bermed excavated material. In 1966, the reservoir was covered (W-0098). In 1986, the beams for the cover were sand blasted and painted. In 1987, the roof beams were inspected for cracks; none were found (W-0909). In 2000, CH2M Hill inspected the reservoir for leaks and a preliminary design was conducted to increase the inflow and outflow piping (WTR-13-0072). The inspection was prompted by a concern that the two Highlands 435 Reservoirs had been damaged in the 1995 Robinson Point Earthquake (5.0 magnitude) as evidenced by wet ground around the chlorination building (further examination discovered the problem was a leaking service line). Because of the concern that these reservoirs will suffer major damage in a large earthquake, the City plans to replace both reservoirs. In 2009, the City performed a preliminary design (WTR-13-0104, Water Distribution Storage Planning Study), which estimated the cost of replacing both reservoirs at $21.3 million for one 15-MG, two-compartment reservoir built in two phases. The reservoir replacement project is currently in final design review (W-3888). 2.2.3.5 Highlands 435 Reservoir – 2-MG (Highlands 435 PZ) Also located at the Highlands reservoir site, this covered, concrete lined, partially in-ground, partially aboveground reservoir was constructed in 1960 (W-0024). In 1986, the beams for the cover were sand blasted and painted. In 1987, the roof beams were inspected for cracks; some were found at the column locations (W-0909). In 1992, reinforcing collars were installed at the roof beam-column intersections and various cracks and joints in the concrete liner were sealed (W-1081). See discussion above for the 2000 inspection and reservoir replacement. There is a project under construction (WTR-27-03888, Replace Highlands Reservoirs and Mains) to replace the two reservoirs in Highlands 435 (Sections 2.2.3.4 and 2.2.3.5) with a 6.4-MG concrete partially buried reservoir. The tank will include a partition dividing it in half, so that it can be cleaned / maintained one half at a time and include replacement of mains along NE 12th from the reservoir site to Edmonds Ave NE and along Monroe Ave next to the site. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 02 2-18 | MAY 2021| FINAL 2.2.3.6 Highlands 565 Reservoir - 0.75-MG (Highlands 565 PZ) Also located at the Highlands reservoir site, this 0.75-MG elevated steel tank was constructed in 1960 (W-0018). CH2M Hill has periodically inspected it over the years (1969, 1973, 1977, 1985 1989, 1998, and 2009). In 1971, an impressed-current cathodic protection system was installed (W-0371). The exterior was recoated in 1978 (W-0476). In 1996, Chicago Bridge & Iron inspected the reservoir. Based on the inspection, the interior and exterior of the reservoir were recoated, the impressed-current cathodic protection system was replaced, and additional railing and a safety climb rail were added in 1997 (W-2210 and W-2303). During the 2001 Nisqually earthquake (6.8 magnitude), the cross bracing of the tower structure was plastically deformed. In 2003, the bracing was repaired and the tank structure seismically rehabilitated (W-3005). The rehabilitation consisted of installing friction dampeners on the cross bracing and flexible connections where the water mains interface with the tank. In 2009, a two-way flow meter was added to the single inlet / outlet pipe that connects the reservoir to the distribution system (W-3214). In 2010, LiquiVision Technology performed a dive inspection of the interior surfaces (WTR-13-0112). The interior protective coating appeared to be in good condition at that time. Norton Corrosion Limited inspected the reservoir’s cathodic protection system in 2017 (WTR-13-0123). They reported that the reservoir had adequate protection based on their testing results. 2.2.3.7 Hazen 565 Reservoir (Highlands 565 PZ) Located north of the Hazen High School campus with address 4901 NE Sunset Boulevard, this 4.2-MG steel standpipe was constructed in 2009 (W-3214). It has flow meters on both the inlet and outlet pipes that connects the reservoir to the distribution system. 2.2.3.8 Rolling Hills 590 Reservoir (Rolling Hills 590 PZ) Located at the Rolling Hills reservoir site near the intersection of Puget Drive SE and Edmonds Avenue SE, this 0.3-MG elevated steel tank was constructed in 1970 (W-0323). The exterior was recoated in 1980 (W-0524). Project W-3005 (see Section 2.2.3.5) also included repairing the Rolling Hills 590 Reservoir. The rehabilitation consisted of installing friction dampeners on the cross bracing and flexible connections where the water mains interface with the reservoir. In addition, both the interior and exterior were recoated and an impressed-current cathodic protection system was installed in 2003. Norton Corrosion Limited inspected the reservoir’s cathodic protection system in 2017 (WTR-13-0123). They reported that the reservoir had adequate protection based on their testing results. Replacement of this reservoir is included in the City’s long-term water CIP (Chapter 9). CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 2-19 Rolling Hills 590 Reservoir 2.2.3.9 Rolling Hills 490 Reservoir (Rolling Hills 490 PZ) Also located at the Rolling Hills reservoir site, this 3-MG aboveground steel reservoir was constructed in 2001 (W-2230). 2.2.3.10 West Hill Reservoir (West Hill 495 PZ) Located adjacent to Dimmitt Middle School near the intersection of 82nd Avenue S and S 126th Place, this 1.3-MG steel standpipe was constructed in 1985 (W-0489). Both the interior and exterior of the reservoir were recoated in 2010 (W-3488). Additionally, two concentric rings of handrail on the top of the standpipe were constructed and an impressed-current cathodic protection system was added as part of Project W-3488. Norton Corrosion Limited inspected the reservoir’s cathodic protection system in 2017 (WTR-13-0123). They reported that the reservoir had adequate protection based on their testing results. 2.2.3.11 South Talbot Reservoir (Talbot Hill 350 PZ) Located on Mill Avenue SE south of Carr Road, this 1.5-MG aboveground steel reservoir was constructed in 1990 (W-0722). CH2M Hill inspected the reservoir in 1998 (WTR-13-0063) and its interior and exterior protective coatings were founded to be in good and very good condition, respectively. In 2008, the exterior was recoated due to pitting that appeared to be from rocks CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 02 2-20 | MAY 2021| FINAL being thrown at the reservoir (W-3449). Water Utility staff performed an inspection of the interior of the reservoir in 2015. The interior protective coating appeared to be in generally good condition, with the exception of rust staining at the locations were the roof beams connect to the walls. The access ladder was also severely corroded at that time.

The Windsor Hills BPS, which had been a backup to the Mt. Olivet and Houser Way BPS, was taken out of service in 2010. A description of each of the facilities is included in the following sections. Table 2.5 provides a summary of each BPS with the rated capacity of each pump. 2.2.4.1 Mt. Olivet Booster Pump Station Located adjacent to the Mt. Olivet Reservoir, the Mt. Olivet BPS pumps from the Valley 196 PZ to the Highlands 435 PZ. The BPS was constructed in 1967 (W-0262). In 1989, one booster pump was added and the electrical, heating, and ventilation systems were rehabilitated (W-0931). In 2007, an emergency electrical power generation facility was constructed at the Mt. Olivet reservoir site to provide backup power for the Mt. Olivet BPS and Wells RW-1, RW-2, and RW-3 (W-3239). This BPS now has emergency backup electrical power with auto-start of the generator and auto-transfer from commercial to backup power. Flow from the station is measured by one meter located in a vault outside the station. The pumps are controlled by the water level elevation in the Highlands 435 Reservoirs. Mt. Olivet Booster Pump Station 2.2.4.2 Houser Way Booster Pump Station Located on the northwest corner of the intersection of Houser Way N and N Marion Street, the Houser Way BPS pumps from the Valley 196 PZ to the Highlands 435 and Kennydale 320 PZs. The BPS was constructed in 1996 (W-2089). The station has a receptacle for an emergency generator hook-up and a manual transfer switch. Meters located inside the station measure flow to the two pressure zones. The pumps are controlled by: 1. The water level elevation in the Highlands 435 PZ reservoirs. 2.

(4) There are two modes of moving water from Skyway to Renton: 1) Pump from Skyway 460 PZ. There is a physical limit of 1,600-gpm in this mode because of limited size of the metered connection to the pressure zone and friction losses. Pumping above 1,600-gpm causes negative pressures on the suction side of the pump. 2) Gravity feed from Skyway 550 PZ via a PRV located in the Dimmitt BPS.

CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 02 2-26 | MAY 2021| FINAL 2.2.4.3 Monroe Avenue Booster Pump Station Located on the northwest corner of the intersection of NE 4th Street and Monroe Avenue NE, the Monroe Avenue BPS pumps from the Highlands 435 PZ to the Highlands 565 PZ. An 8-inch supervisory control and data acquisition (SCADA) controlled transfer valve can allow flow from the Highlands 565 PZ to the Highlands 435 PZ. The valve is used in coordination with the Maplewood BPS when water is being pumped to the Highlands 565 PZ. The BPS was constructed in 1969 (W-0324). In 1991, the station’s electrical system was rehabilitated (W-1048). Flow from the station is measured by one meter located in the station. The pumps are controlled by the water level elevation in the Highlands 565 Reservoir. The pump station does not have emergency power backup capability. Installing backup power is included in the City’s short-term water CIP (Chapter 9). 2.2.4.4 Highlands Booster Pump Station Located at the Highlands Reservoir site, the Highlands BPS pumps from the Highlands 435 PZ to the Highlands 565 PZ. The BPS was constructed in 1960 (W-0018). In 1989, two pumps and motors were replaced and the third pump was rebuilt; the electrical system was also rehabilitated (W-0924). An isolation valve was installed in 1992 (W-1023). In 2003, the wooden doors on the west side of the building were replaced with metal. This station has emergency power backup with auto-start and auto-transfer (W-0815). A new 275 kW electrical generator with auto start / auto transfer was completed in 2017 (WTR-27-03759). Flow from the station is measured by one meter located in a vault outside the station. The pumps are controlled by the water level elevation in the Hazen 565 Reservoir. Replacement of this pump station is planned to occur concurrently with the Highlands 435 Reservoirs Replacement Project. Highlands Booster Pump Station CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 2-27 2.2.4.5 North Talbot Booster Pump Station Located near the intersection of SR 515 (Benson Road) and South 19th Street, the North Talbot BPS pumps from the Valley 196 PZ to the Rolling Hills 490 and Talbot Hill 350 PZs. It originally pumped to the Rolling Hills 590 PZ and Talbot Hill 350 PZ. The BPS was constructed in 1979 (W-0450). A manual transfer switch with Kirk-Key safety system was added in 1999 to allow the station to be powered by a City-owned portable generator (W-2784). In 2007, an emergency electrical power generation facility was constructed at the North Talbot Reservoir site to supply power to the North Talbot BPS (W-3239). The power is auto-start and auto-transfer. The portable generator and manual transfer switch configuration remains as a secondary backup. In 2001, a backpressure sustaining valve was added to the station’s primary discharge when a portion of the Rolling Hills 590 PZ was converted to the Rolling Hills 490 PZ as part of the Rolling Hills 3 MG reservoir and pump station project (W-2230). The station’s electrical, heating, and ventilation and control systems were rehabilitated in 2003 (W-2878). Flow to the two pressure zones is measured by meters located inside the station. The pumps are controlled by: 1. The water level elevation in the Rolling Hills 490 Reservoir. 2. The water level elevation in the South Talbot Reservoir. North Talbot Booster Pump Station CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 02 2-28 | MAY 2021| FINAL 2.2.4.6 Rolling Hills Booster Pump Station Located at the Rolling Hills reservoirs site, the Rolling Hills BPS pumps from the Rolling Hills 490 PZ to the Rolling Hills 590 PZ. The BPS was constructed in 2001 (W-2230). Two backpressure sustaining valves in the pump station allow water to flow from the Rolling Hills 590 PZ to the Rolling Hills 490 PZ when the Rolling Hills 590 Reservoir is near overflow. This allows the Rolling Hills 3-MG reservoir to be filled by either the Maplewood BPS or the North Talbot BPS. Two flow meters are located inside the station. One flow meter measures flow from the Rolling Hills 490 PZ to the Rolling Hills 590 PZ. Another meter measures flow from the Rolling Hills 590 PZ to the Rolling Hills 490 PZ. The pumps are controlled by the water level elevation in the Rolling Hills 590 Reservoir. This pump station is equipped with an emergency generator with auto-start and auto-transfer, but only allows two pumps to operate at the same time. It is recommended that backup power be installed such that all four pumps can be operated at the same time. This project is included in the City’s short-term water CIP (Project ST-01 in Chapter 9). 2.2.4.7 Tiffany Park Booster Pump Station Located in Tiffany Park near the intersection of Kirkland Avenue SE and SE 20th Court, the Tiffany Park BPS pumps from the SPU 66-inch Cedar River transmission main to the Rolling Hills 590 PZ. The BPS was constructed in 1962 (W-0226). The pumps were replaced in 1972 (W-0383). The entire station was rehabilitated in 1984 (W-0742) but does not have emergency power backup capability. In 2011, a flow meter was installed. The pumps are controlled by the water level elevation in the Rolling Hills 590 Reservoir. CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 2-29 Tiffany Park Booster Pump Station 2.2.4.8 Fred Nelson Booster Pump Station Located adjacent to the Nelsen Middle School on Benson Road S, the Fred Nelson BPS pumps from SPU 60-inch Bow Lake transmission main to the Rolling Hills 590 PZ. The BPS was constructed in 1962 (W-1125). It does not have emergency power backup capability. In 2011, a flow meter was installed. The pumps are controlled by the water level elevation in the Rolling Hills 590 Reservoir. 2.2.4.9 Maplewood Booster Pump Station Located at the Maplewood Golf Course, the Maplewood BPS pumps from the clearwell to the Highlands 565 and Rolling Hills 590 PZs. The BPS was constructed in 1995 (W-1052). The BPS roof was replaced in 2016 (W-3765). Flow to the two pressure zones is measured by meters located inside the station. The pumps are controlled by: 1. The water level elevation in the Highlands 565 Reservoir. 2. The water level elevations in both the Rolling Hills 490 and 590 Reservoirs. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 02 2-30 | MAY 2021| FINAL The Maplewood Treatment and BPS Facility is equipped with a manual transfer switch with Kirk-Key safety system that allows one production well, one booster pump, and associated treatment equipment to be powered by a City-owned portable generator (W-2953). It is recommended that auto-start and auto-transfer capability be installed at the Maplewood BPS. This project is included in the City’s short-term water CIP (Chapter 9). 2.2.4.10 South Talbot Booster Pump Station Located on SW 43rd Street just west of SR 167, the South Talbot BPS pumps from the Valley 196 PZ to the Talbot Hill 350 PZ. The BPS was constructed in 1982 (W-0600). A manual transfer switch with Kirk-Key safety system was added in 1999 to allow the station to be powered by a City-owned portable generator (W-2784). Flow from the station is measured by one meter located in the station. The domestic pumps are controlled by the water level elevation in the South Talbot Reservoir, while the fire flow pumps are controlled by the pressure of the Talbot Hill 350 PZ measured at the station. Note that only one fire pump can operate at a time. Installing emergency backup power at the South Talbot BPS is currently in preliminary design (WTR-13-0129) and is included in the City’s short-term water CIP (Chapter 9). 2.2.4.11 West Hill Booster Pump Station Located on West Perimeter Road at the Renton Municipal Airport near the control tower, the West Hill BPS pumps from the Valley 196 PZ to the West Hill 495 PZ. The BPS was constructed in 1985 (W-0715). It has one 1,000-gpm fire pump that is driven by a diesel engine with auto-start and two 600-gpm domestic pumps. Flow from the station is measured by one meter located in the station. The pumps are controlled by the water level elevation in the West Hill Reservoir. Installing emergency backup power at the West Hill BPS is currently in preliminary design (WTR-13-0129) and is included in the City’s short-term water CIP (Chapter 9). 2.2.5 Pressure Reducing Stations PRV stations are installed between pressure zones and allow water from a higher-level pressure zone to flow into a lower level pressure zone at reduced pressures. The PRVs in the pressure reducing stations hydraulically vary the flow rate through the valve to maintain a constant and preset discharge pressure up to the limit of the flow capacity of the valve. The effect of a PRV on the lower pressure zone is the same as that as a reservoir whose overflow elevation is the same as the pressure setting on the valve (hydraulic elevation). Lead PRVs are located in hydraulically remote areas from both upper and lower pressure zone reservoirs to promote good circulation in both pressure zones, thus maintaining water quality. Lag PRVs may be located hydraulically closer to storage to minimize system head losses during high flow rate conditions when the lag valves need to operate. The primary purposes of the PRVs in the City’s system are as follows: 1. To maintain pressures in the lower pressure zone during high demand periods. 2. To increase pressure and flow which would otherwise be required during an emergency such as a fire or pipeline failure. 3. To achieve optimum circulation in each pressure zone, thereby maintaining water quality. When a PRV malfunctions in an open position and allows downstream pressures to rise above the PRV setpoint, damage can occur due to over pressuring of the pressure zone. The probability CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 2-31 of over pressuring the lower pressure zone can be greatly reduced by placing a pressure relief valve on the discharge (pressure-reduced) side of the PRV. If a pressure sensor is also installed on the PRV discharge and the pressure reading is telemetered and alarmed at the central control center, the City will know quickly when the failure is occurring and will be able to minimize damages as a result of the PRV failure. The City’s PRV stations currently in operation are listed in Table 2.6. WTR-13-00130 (PRV Station Rehabilitation and Replacement Study) occurred in 2018. The following list provides additional information on PRV stations that are no longer in operation: • PRV Stations 17, 18, 19, 20, 21, and 33 were put on inactive status (zone valves opened; PRVs set to wide open) in 2001 as part of the reconfiguration of the Rolling Hills 490 and 590 PZs following the completion of the Rolling Hills 3-MG Reservoir and BPS project (W-2230). • PRV Station 6 is closed and out-of-service. • PRV Station 11 was removed in 1995 (W-2126). • PRV Station 15 was removed in 1992. • PRV Station 27 was removed in 1992. • PRV Station 42 was removed in 2000.

CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 2-41 The City’s system is comprised of two types of pipes: • Transmission pipelines, and • Distribution pipelines. 2.2.6.1 Transmission Mains Transmission capability for the system is primarily provided by 12-inch, 16-inch, and 24-inch diameter pipelines that convey water from the wellfields located in Liberty Park, Cedar River Park, and the Maplewood Golf Course to various points within the service area. Transmission mains generally convey water between the supply sources (reservoirs or wells) to the local distribution grid and individual customers. Ideally, minimal head loss should occur in transmission pipelines during normal demand periods, allowing these mains to also convey fire demands to the distribution system and to meet other emergencies without experiencing adverse head losses. Since approximately 96 to 97percent of the system’s supply is provided from the wellfields and artesian spring, major transmission facilities are required in the Valley 196 PZ to ensure adequate water distribution throughout the service area. As shown in Figure 2.1, the transmission pipelines are located primarily along the major transportation corridors. The looped 8-inch pipelines in the well-developed residential areas of the system also provide some transmission capability: • Transmission pipelines in the Valley 196 PZ predominantly run north to south, supplying the downtown business pressure zone, the Green River Valley industrial complexes, and the BPS that serve the other areas of the system. • East-west pipelines that connect to the north-south transmission mains also provide additional transmission capacity. The pipe loops or grids formed by these connections help to increase system reliability and capacity throughout the system. • Transmission pipelines from the Maplewood Wellfield carry finished water to the Highlands and Rolling Hills PZs. Both transmission pipeline routes follow unimproved corridors and steep slopes. A high-pressure fire loop (320-ft hydraulic grade line) encompasses a high-risk area of the industrial sector near the Paccar and Boeing plants for improved fire protection. • For areas on the eastern side of the valley, the topography of the terrain dictates that the transmission corridors run in a north-south orientation within each pressure zone and in a west-east orientation between the different pressure zones. • The transmission corridor in the West Hill area runs east and west from the West Hill BPS to the reservoir and north and south on 84th Avenue S. A separate transmission route connects the reservoir with Skyway Water and Sewer District. Looped 8-inch and 6-inch distribution mains provide a large percentage of the transmission capacity in the West Hill area. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 02 2-42 | MAY 2021| FINAL Pipeline -Flex Joint Installation 2.2.6.2 Distribution Mains Unlike, transmission pipes, the distribution system functions by meeting individual demands in the immediate vicinity via branching and looping pipelines through the service area. Figure 2.1 also presents the smaller pipelines, below 12 inches in diameter, which convey water from the transmission grid to the individual service connections. The transmission and distribution system is comprised of water mains of four different materials: asbestos cement, steel, ductile iron, and cast iron. Current City policy is to replace all asbestos cement and steel water mains in the system as the budget permits, since transmission lines made of these materials are prone to leakage and failure. The City completed deployment of Advanced Metering Infrastructure (AMI) throughout the entire system in 2015 (W-3499). The AMI system enhances the City’s water conservation activities, improves leak detection capabilities, and optimizes pumping of the City’s water supply wells. 2.2.7 Treatment The City began chlorinating its drinking water in 1976. Each source treatment is currently designed with primary disinfection to provide 4-log inactivation of viruses (CT of 6 mg-min/L) and the City maintains a chlorine residual between 0.6 and 1.0 milligrams per liter (mg/L) throughout the distribution system. CT pipelines were installed at Springbrook Springs and in Liberty Park and Cedar River Park for the Downtown Wells. Primary disinfection at Wells PW-11, PW-12 and PW-17 occurs at the Maplewood Water Treatment Plant as a result of the treatment process to remove ammonia from the raw water. Water in the Chlorine Contact Basin and Clearwell has a contact of at least four hours before entering the distribution system. Each source is equipped with an automatic shutdown and alert notification when the chlorine residual drops below a safe level. Renton citizens voted for fluoridation in 1985. The current fluoride target dose is 0.7 mg/L, as recommended by DOH. Wells RW-1, RW-2, RW-3, and EW-3R have fluoride saturation and metering equipment located in the wellhouses. Wells PW-8 and PW-9 are served by the CHAPTER 02 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 2-43 Fluoridation Building, which is located next to Well PW-8. This building also serves as a storage facility for bagged sodium fluoride. Fluoridation for Wells PW-11, PW-12, and PW-17 occurs in the Maplewood BPS and Treatment Building. In 1999, the City began treating the water from the Downtown Wells and Springbrook Springs with sodium hydroxide to raise the pH of the water. The goal is to decrease the corrosivity of the water and to comply with the Lead and Copper Rule. For the Downtown Wells, sodium hydroxide is stored at the Corrosion Control Treatment Facility (CCTF) located in Cedar River Park. From this facility, diluted sodium hydroxide is fed to each of the Downtown Wells via HDPE pipes. At Springbrook Springs sodium hydroxide is fed from a storage building, which is located adjacent to the chlorination building. A corrosion inhibitor and sequestering agent (Aqua Mag®) is also used for additional corrosion control in areas of the distribution system that contain a high number of unlined cast iron water mains. In 2006, the City redesigned the treatment method at Maplewood to include the removal of manganese using greensand filters, hydrogen sulfide using GAC, and ammonia using sodium hypochlorite. Maplewood Treatment Facility 2.2.8 Telemetry and SCADA The telemetry and SCADA systems for the water system have changed over the years with the changes in technology that is available. The following is a brief description of the current system. Certain aspects of operation and capability are not discussed for security reasons. Each site (all sources, all booster pump stations, all reservoirs, all treatment facilities, Boeing Longacres Intertie, Skyway Wholesale Meter, Dimmitt BPS, Coal Creek emergency intertie) has a remote telemetry unit (RTU) that in some cases also serves as a programmable logic controller (PLC). Information about the site is forwarded from the site to the master telemetry unit (MTU) that is located at the Water System Control Room (City Shops Administration Building). The MTU CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 02 2-44 | MAY 2021| FINAL sends information and instructions back to the RTUs. Signals between the RTUs and MTU travel either by dedicated phone lines or by radio waves. At the Water System Control Room, the operations staff monitor (and control as necessary) the system using a Human Machine Interface (HMI). The HMI is a PC running software that communicates with the MTU and can display information. The HMI computer also runs an auto-dialer application (Win 911) that calls a 24-hour manned call service and/or water shop stand-by staff. There is a backup auto-dialer that is used in the event the HMI computer or MTU fails. Each RTU, the MTU, and the HMI computer have various levels of backup power and redundancy. Various analog (e.g., flow rate, water elevation), discrete (e.g., pump status), and alarm information is stored in a SQL Server database for historical and analysis purposes. By 2016, the City finished upgrading its MTU and RTUs to Emerson Control Wave Micro equipment (W-3826). All radios were changed to Viper SC 450-512-megahertz (MHz) radio units in 2015. The City also added fiber connection for North Talbot BPS, North Talbot Reservoir, North Talbot generator building, Mt. Olivet BPS, Mt. Olivet Reservoir, and Mt. Olivet generator building in 2017 (W-3885).

CHAPTER 03 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 3-1 Chapter 3 DEMAND PROJECTIONS 3.1 Introduction and Methodology Overview Three future water demand scenarios (Low, Medium, and High) were projected for the City of Renton (City) using the following information: • Historical production and consumption trends from 2008 to 2017. • Puget Sound Regional Council (PSRC) demographic projections. • Future predictions of the impacts placed on demands by factors such as water use efficiency (WUE), climate change, and the expected future consumption of the City’s largest water consumers. The Medium scenario's predictions most closely resemble the City’s future demands, while the Low and High demand projection scenarios provide a range that the City’s future water demands are expected to fall within. The High and Medium scenarios were used in the Chapter 6 supply analysis, which describes when the City must supplement its own supply with wholesale water purchased from Seattle Public Utilities (SPU). The Medium scenario was used for the Chapter 7 system analysis, which determines future pumping, storage, and distribution system requirements. Between 2008 and 2017, the City’s average day demand (ADD) was approximately 7 million gallons per day (mgd). During that time, historical maximum day demands (MDD) were approximately 13 mgd. The City’s typical Single-Family household consumes 159 gallons per day (gpd). For demographic trends, PSRC predicts approximately 1 percent annual growth in the number of City households and 1.9 percent annual growth in the number of employees over the 20-year planning period. The same projections for each pressure zone (PZ) were used to also predict the number of future water connections in the system. The City’s WUE program will also affect future demands. To plan its water system, the City selected three measurable WUE goals, which were incorporated into the demand projections: 1. Limit the peaking factor to less than 2.0. 2. Reduce distribution system leakage (DSL) to 10 percent or less by 2022. 3. Maintain an equivalent residential unit (ERU) value under 160 gpd/ERU. 3.2 Land Use The City’s water service area encompasses the majority of the Renton city limits, small portions of unincorporated King County, and a few parcels within the City of Tukwila. Northwest of Interstate 405 (I-405) and west of Washington highway 167 (WA-167), the City is predominantly commercial and industrial, while the areas east of I-405 and WA-167 are less dense and more residential. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 03 3-2 | MAY 2021 | FINAL Figure 3.1 shows the City’s zoning, which was used as the baseline for the analysis presented in this chapter. Figure 3.2 shows the City’s existing land use, while Figure 3.3 shows future land use based on zoning of the City and King County. For this Plan, the City’s zoning and land use data was compiled into 11 land-use designations as follows: • Agriculture. • Commercial. • Industrial. • Mixed Use. • Multi-Family. • Open Space. • Park. • Public/Quasi-public. • Right of Way. • Single-Family. • Vacant. The City’s Comprehensive Plan encourages high-density, mixed-use redevelopment of the City Center, South Lake Washington/Southport area, and Sunset Neighborhood. Much of the City’s vacant parcels are zoned for industrial and commercial purposes. 3.3 Historical Supply and Consumption To help Carollo Engineers, Inc. (Carollo) establish historical demand trends, the City provided historical water purchase records, the number of connections, and consumption data between 2008 and 2017. The data was then evaluated to characterize the unique water use of the City’s customers, generate several key demand parameters, and predict future water demand.

Springbrook Springs and the City's wells produce most of the water for the City's customers. Wholesale water purchased from SPU primarily serves the Boeing Renton Plant through two metered connections. The SPU water mains supplying the Boeing Plant are isolated from the rest of the City’s water system. When necessary, the City can purchase water from SPU through other interties to supplement its supply. Table 3.1 shows the City’s monthly production in 2017 by supply source, while Table 3.2 lists the historical annual production from 2008 through 2017. As shown, the annual production ranged from a low of 2,411 million gallons (MG) in 2012 to a high of 2,799 MG in 2009. Figure 3.4 shows the average production percentage by source from 2008 to 2017. As shown, the City relies on Wells RW-1, RW-2, and RW-3 for more than half of its water supply. When water demands are elevated, these wells account for 52 percent of water produced by the City. Other major sources of supply include Springbrook Springs, the Maplewood Wellfield (PW-11, PW-12, and PW-17), and Well PW-8, which accounted for 18 percent, 17 percent, and 11 percent, respectively. The remaining 2 percent consisted of water purchased from SPU for the Boeing Renton Plant. 3.3.1.1 Average Day Demand ADD is a water system’s average daily demand for a year. To calculate ADD, the total water produced by the City over a year is divided by the number of days in the year. Table 3.3 and Figure 3.5 show ADD values from 2008 through 2017, which average out to 7 mgd during that time.

MDD must be established to determine system requirements for supply capacity, pump station discharge rates, and reservoir capacity. The MDD and date of occurrence for each year since 2008 are also shown in Table 3.3. As this table and Figure 3.5 show, MDD has fluctuated around 13 mgd with no definitive trend moving up or down. The historical MDD to ADD peaking factor is also a key parameter used to develop future MDD projections. The City’s average historical peaking factor is 1.8, while the MDD to ADD peaking factor fluctuated between 1.7 in 2008 and 1.9 in 2009.

By the end of 2017, the City provided water to 17,831 connections. Table 3.4 and Figure 3.6 show the historical number of connections per customer type. Table 3.5 shows the total number of connections in 2017 as distributed by pressure zone. Figure 3.7 shows the average percent of connections by customer category from 2008 through 2017. For this Plan, the City’s thirteen customer classes were consolidated into the following eight categories: • Single-Family Residential: Single-Family homes accounted for 77 percent of customer connections in 2017. From 2008 through 2017, Single-Family Residential connections increased by 801 connections, which corresponds to roughly a 0.7 percent annual growth. • Multi-Family Residential: Multi-Family housing, including Duplexes, accounted for about nine percent of customer connections in 2017. Because the City tracks the number of dwelling units per residential customer, Multi-Family Residential water consumption trends are reported per dwelling unit. Between 2009 and 2017, the number of Multi-Family Residential dwelling units served by the City increased by 330. (Note that reliable statistics for Multi-Family dwelling units were not available in 2008.) This corresponds to an annual growth rate of 0.3 percent. • Commercial: Commercial accounted for six percent of customer connections in 2017. From 2008 through 2017, Commercial connections increased by 32 connections, corresponding to a 0.3 percent annual growth. • Industrial: Industrial accounted for less than one percent of customer connections in 2017 and has not grown within the last decade. • Government: Government combines two customer classes (City and School, State, Federal). Government connections accounted for less than one percent of connections in 2017. From 2008 through 2017, Government connections grew by eight connections, or roughly 1.2 percent annually. • Irrigation: Irrigation consists of the City’s Irrigation and Irrigation from the other customer classes. Multi-Family Housing Developments, Mobile Home Parks, Schools, Commercial Complexes, and Industrial Plants often have separate connections for irrigation. Between 2008 and 2017, Irrigation connections accounted for 3.4 percent of the system and grew by 0.6 percent annually. • Other Authorized Use: Other Authorized Use combines two customer classes (Hydrants and Fire). Commercial and Multi-Family Residential customers often have separate connections for fire suppression. Revenue water is also sold to contractors and tracked by portable hydrant meters checked out to the contractor. • Largest Consumers: The City’s six Largest Consumers were evaluated separately. The City supplies wholesale water to the Skyway Water and Sewer District (Skyway) through one connection located in the West Hill 495 PZ. Wholesale water is purchased from SPU and sold to the Boeing Plant through two connections. Other large consumers include the King County South Plant, Valley Medical Center, G&K Services, and Service Linen Supply. (Note that throughout this analysis, the King County South Plant connection was subtracted out of the Industrial category and the Valley Medical Center, G&K Services, and Service Linen Supply connections were subtracted out of the commercial category).

CHAPTER 3 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 3-19 Figure 3.7 Percent of Connections by Customer Category (2008-2017) 3.3.3 Historical Water Consumption Using the City’s billing records, Carollo obtained data on the annual water consumption of each customer category from 2008 to 2017. This data is shown in Table 3.6. Although Single-Family Residential customers make up 77 percent of the City’s connections, they consumed only 35 percent of total retail water sales. The Multi-Family Residential customers accounted for 23 percent of water use, meaning that a majority of the City’s water sales consisted of residential water use. Figure 3.8 shows that Commercial customers accounted for 15 percent of water sales and Industrial customers accounted for three percent. The City’s six Largest Consumers alone accounted for 10 percent of water sales. Government customers accounted for 1 percent of water sales. Although comprising only three percent of the total number of accounts, Irrigation use accounted for 12 percent of the total water used. Figure 3.9 shows how consumption for each customer category changed between 2008 and 2017. Despite adding many new residential connections, Single-Family and Multi-Family Residential consumption grew very little over this time. As indicated by their annual consumption growth rates in Figure 3.9, Commercial, Irrigation, and the Largest Consumers had the most growth. Other Authorized Use included billed consumption from Hydrant and Fire connections plus unbilled consumption that was authorized by the City (Authorized Non-Revenue Water). With the City's improved tracking of unbilled water use, Authorized Non-Revenue Water (water used by City maintenance and by Renton Regional Fire Authority [Renton RFA]) also grew significantly. Other Authorized Use increased from 0.6 percent in 2008 to a high of 1.8 percent in 2016 and averaged 1.3 percent of the City’s overall water consumption.

Each of these customers has an annual water demand exceeding 40,000 gpd. The seventh largest consumer used less than 15,000 gpd, making the top six a natural cutoff for customers that must be evaluated in more detail. The City provides wholesale water to Skyway and sells water to Boeing’s Renton Plant, the King County South Plant, Valley Medical Center, G&K Services, and Service Linen Supply. To more precisely predict the magnitude and location of their future demands, consumption trends for these customers were evaluated individually. Figure 3.10 shows the historical consumption for these connections between 2008 and 2017. Wholesale to Skyway and consumption at the King County South Plant increased steadily. Figure 3.11 shows the locations of the City’s six Largest Consumers.

Deterioration of the City’s aging water infrastructure leads to real losses such as water main breaks, reservoir leaks or overflows, and general distribution system leakage. However, it is important to note that the DSL includes apparent losses other than leakage such as meter inaccuracy or failure, data handling errors, water theft, and untracked authorized water use. Table 3.7 lists the total water production, total authorized consumption, and DSL between 2008 and 2017. Figure 3.12 plots the DSL trends during this time. The average DSL was 12.5 percent, which is a reduction of 5.3 percent since the previous Water System Plan. The City's goal is to reduce the DSL to 10 percent or less. To this end, the City deployed an Advanced Metering Infrastructure (AMI) system in 2011, which helps the City more accurately compare production and consumption and better detect stuck meters, meter tampering, and water theft. Authorized Non-Revenue Water that is not tracked by the City contributes to the DSL. Based on recommendations in the last Water System Plan, the City installed a meter at the Regional Firefighting Training Facility in 2018 to track the fire department's authorized water use and also installed meters at the King County South Plant in 2019 to track currently authorized, but unmetered, water use. Once metered, the authorized water consumption will be subtracted out of the DSL. In accordance with Washington State requirements for systems with DSL in excess of 10 percent, the City prepared a Water Loss Control Action Plan (WLCAP). This document is included in Appendix G. The leakage percentages in Table 3.7 may slightly differ from the ones reported to the Washington State Department of Health (DOH). The City historically reported raw meter data to DOH. With the upgrade to AMI data, the City has been resolving data issues and the updated data is shown in Table 3.7. In the future, the City will report water use data to DOH using the updated method.

Figure 3.13 depicts the variation in average monthly water consumption from 2008 to 2017, along with average monthly precipitation during that time. Figure 3.14 and Figure 3.15 show the variation of water use for each customer category throughout the year, which is based on average monthly water use between 2015 and 2017. While most of the City’s customers are billed monthly, some customers are billed bi-monthly. This accounts for the month-to-month fluctuations in water consumption for customer categories with fairly consistent water consumption throughout the year, such as Multi-Family Residential customers. 3.3.5 Water Consumption per Connection Table 3.8 shows annual water consumption per connection for each customer category. For forecasting and planning, individual demand is expressed as ERU.

According to the Washington Administrative Code (WAC) 246-290-010, non-residential customer water use is expressed as a multiple of Single-Family Residence ERU. To calculate ADD water use per ERU, the total annual volume of water consumed by Single-Family Residences is divided by the total number of active Single-Family Residential connections. The resulting value, also called the ERU planning value, is the average Single-Family Residence’s annual water use per connection. To determine the number of ERUs used by other customer categories, the volume of water used by those customer categories is divided by the ERU value. Table 3.8 shows each customer categories’ average daily consumption per connection between 2008 and 2017. The Single-Family Residential average consumption volume was 159 gpd during that time. As shown in Figure 3.16, the City’s ERU value generally declined over the last decade and has remained below 160 gpd since 2010. Since one of the City's WUE goals is to keep its ERU value under 160 gpd, the City has selected 160 gpd as its ERU planning value. The last column in Table 3.8 shows the average number of ERUs per connection for each customer category the City serves. This is calculated by dividing the consumption per connection by the ERU planning value. The typical Multi-Family dwelling unit consumes 0.6 ERUs, meaning that a Multi-Family household consumes 60 percent of the water of a typical Single-Family household. Non-residential connections use significantly more water than a typical Single-Family Residence, with a range of 5.6 to 16.0 ERUs. Table 3.9 lists each customer categories’ number of ERUs between 2008 and 2017.

The PSRC publishes population, household, and employee growth forecasts for jurisdictions within its regional boundary. The PSRC database contains historical and future yearly estimates of key demographic and employment values for the Puget Sound region by forecast analysis zone (FAZ). The City’s RWSA and pressure zone boundaries do not coincide with the PSRC’s FAZ boundaries. As a result, the City allocated key demographic and employment variables (households, population, and employees) to each pressure zone within its service area using GIS techniques. Table 3.10 shows the PSRC’s population, household, and employment projections. Table 3.11 shows the PSRC’s population projections by pressure zone, and Table 3.12 shows the employment projections by pressure zone.

Household growth rates were used to project Single-Family Residential and Multi-Family Residential connections. Employment growth rates were also used to forecast connections for all Non-Residential customer categories (Commercial, Industrial, Government, and Irrigation). Table 3.13 and Table 3.14 show annual growth rates for each pressure zone. Note, the City assumed that negative growth will not occur, so growth rates were set to the minimum value between the calculated value and zero. PSRC predicts the greatest residential growth rates in the Renton Highlands zones, as shown in Table 3.13, while the Valley 196 PZ and Kennydale 320 PZ will experience the highest commercial growth in terms of the number of employees added, as illustrated in Table 3.14. The PSRC also predicts the number of households within the City’s RWSA to grow by one percent annually between 2017 and 2040. This projection is higher than the 0.7 percent annual growth rate for Single-Family Residential connections experienced in the City between 2008 and 2017 (Figure 3.6). Furthermore, the PSRC predicts that employment within the City’s RWSA will experience an annual growth rate of 1.9 percent from 2017 to 2040. This projection more than doubles the annual growth rates of Commercial and Industrial that the City experienced between 2008 and 2017.

Demand projections are used to identify the system improvements required for supply, pumping, storage, and piping infrastructure. This section summarizes the ADD and MDD projections Carollo developed for the City's water system using historical water demand trends and the future demographic growth assumptions developed in Section 3.4. Demand projections are presented for three demand scenarios (Low, Medium, High) that represent a range in potential future demands. Low, Medium, and High water demand projection scenarios were developed by adjusting various demand projection parameters: • The Low scenario assumes aggressive WUE, which represents the lowest future demands the City expects to experience. • The Medium scenario is a planning case predicted to most closely match the City’s future demands. • The High scenario assumes no intentional WUE, which represents the highest demands the City could experience. Both Medium and High scenarios were used in the Chapter 6 supply analysis, which will help the City to decide when to acquire new water rights and develop new supply sources. The Medium scenario was used for the Chapter 7 system analysis, which identifies deficiencies in future pumping, storage, and the distribution system analyses, as well as size potential improvements to achieve the City’s established capacity criteria. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 03 3-42 | MAY 2021 | FINAL 3.5.1 Demand Projection Methodology For this analysis, water demand projections were developed in the following steps: 1. Increase historical water connection numbers for each pressure zone and customer type (as shown in Tables 3.4 and 3.5) by the zone-specific residential and non-residential growth rates from the demographic analysis (as shown in Tables 3.13 and 3.14). Table 3.15 shows the resulting connection projections. 2. Convert connection projections into ERU projections using the historical ERUs per connection (as shown in Table 3.8). 3. Convert ERU projections to ADD projections using demand projection parameters derived from historical data of the City's starting ERU value, DSL/Non-Revenue Water, Other Authorized Use, climate change impact, and Largest Consumer demand. City staff established unique demand projection parameters for Low, Medium, and High demand scenarios. 4. Apply the MDD to ADD peaking factor to convert ADD to MDD. Again, each demand scenario has a unique peaking factor selected by City staff. Figure 3.17 also summarizes these steps. 3.5.2 Demand Projection Parameters To project the City's future ADD and MDD, several parameters were used: • ERU value. • ERU value annual reduction. • DSL/Non-Revenue Water. • Other authorized use. • Climate change scenario. • Largest Consumer demand. • MDD to ADD peaking factor. For each of the above parameters, the City used historical data to establish Low, Medium, and High values, which were used to develop each of the demand projection scenarios. This information is summarized in Table 3.16 and discussed in further detail in the following subsections. CHAPTER 03 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 3-43 Figure 3.17 Demand Projection Methodology CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 03 3-44 | MAY 2021 | FINAL Table 3.16 Demand Projection Parameters Demand Projection Scenario Low Medium High Value Notes Value Notes Value Notes ERU Value (gpd/ERU) 153 Historical Minimum 160 WUE Goal 173 Historical Max DSL/Non-Revenue Water (Percent of Production) 10% WUE Goal 12.5% Historical Average 12.5% Historical Average Other Authorized Use (Percent of Production) 1.3% Historical Average 1.8% Historical Maximum 2.0% Climate Change Scenario None Warm Warmest MDD/ADD Peaking Factor 1.7 Historical Minimum 1.8 Historical Average 2.0 WUE Goal 3.5.2.1 ERU Value The City selected a unique ERU value for each demand projection scenario. As mentioned before, the ERU value represents the consumption of a typical Single-Family household in gpd and is used to convert the number of ERU projected to ADD projections. For the Low scenario, the City selected an ERU value of 153 gpd/ERU, which is the lowest value experienced between 2008 and 2017. An ERU value of 160 gpd/ERU was selected for the Medium scenario, which corresponds to the City’s WUE goal, while the High scenario used an ERU value of 173 gpd/ERU, corresponding to the highest ERU value the City experienced between 2008 and 2017. 3.5.2.2 Distribution System Leakage The City’s goal is to reduce its DSL and Non-Revenue Water to 10 percent or less, which is reflected in the Low scenario. The Medium and High scenarios conservatively assume the City will not able to meet its goal and DSL and Non-Revenue Water will remain at 12.5 percent, the average value between 2008 and 2017. 3.5.2.3 Other Authorized Use (Hydrants and Fire) Other Authorized Use is a small percentage of the City’s water production. The historical average value of 1.3 percent was selected for the Low scenario. As the City improves its tracking of authorized use to lower DSL, it expects that Other Authorized Use may increase. Therefore, the historical maximum of 1.8 percent was selected for the Medium scenario, while the High scenario used 2 percent. CHAPTER 03 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 3-45 3.5.2.4 Impact of Climate Change on Demand Projections According to climate change models, the Pacific Northwest will, in general, experience warmer, wetter winters and hotter, drier summers. To estimate climate change's impact on the City’s water demands, Carollo examined results from the Water Supply Forum’s 2009 Regional Water Supply Outlook, which forecasted demands for the Puget Sound Region under three general circulation models (climate change models) developed by the University of Washington. For the purpose of this Plan, these models were nicknamed Warm, Warmer, and Warmest: • The Warm model predicted a small increase in temperature and a small decrease in annual precipitation. • Compared to the Warm model, the Warmer model predicted a medium increase in temperature and a small increase in annual precipitation. • The Warmest model predicted the highest increase in temperature and also the highest increase in precipitation. Using each model’s climate predictions, water demands for the Puget Sound Region were projected and compared to a baseline demand projection scenario that assumed no change in temperature or precipitation. Table 3.17 shows the difference in demand for each climate change scenario compared to the baseline. The Warm and Warmest models were applied to the Medium and High demand projection scenarios, respectively. According to the Warm model, an approximately 2 percent increase in demands is predicted by 2040. The Warmest model, on the other hand, predicts a roughly 5 percent increase in demands by 2040. The Low scenario assumes no impact from climate change. Table 3.17 Predicted Increase in Demand from Baseline due to Climate Change Climate Change Scenario 2005 2010 2020 2030 2040 Baseline 0.0% 0.0% 0.0% 0.0% 0.0% Warm 0.0% 0.2% 0.8% 1.4% 2.1% Warmer 0.0% 0.1% 0.5% 1.4% 3.1% Warmest 0.0% 0.4% 1.4% 2.9% 4.9% 3.5.2.5 MDD to ADD Peaking Factor The City’s WUE goal is to maintain a peaking factor of less than 2.0, which is higher than historical trends show. This peaking factor was applied to the High scenario. The City anticipates that increased WUE and conservation measures may reduce annual water consumption, thereby increasing the peaking factor. The historical average peaking factor of 1.8 was used for the Medium scenario, and the historical minimum peaking factor of 1.7 was used for the Low scenario. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 03 3-46 | MAY 2021 | FINAL 3.5.2.6 Largest Consumer Demand Using analyses of the City’s historical consumption, Carollo developed individual demand projections for the City’s six Largest Consumers, as shown in Table 3.18. Each of the Largest Consumers was assigned a starting demand (the demand for 2017 in the projections) and an annual growth rate dependent on the demand scenario (Low, Medium, High). Details for each of the Largest Consumers are provided below. Over the last decade, the annual consumption of Boeing, Valley Medical Center, G&K Services, and Service Linen Supply remained fairly constant. Therefore, no growth is projected for these customers. For all demand scenarios, the starting demand for Boeing, G&K Services, and Service Linen Supply was set to their annual average demand from 2008 to 2017. For Valley Medical Center, the Low scenario’s starting demand was set to the historical average, while the Medium and High scenarios’ starting demands were set to their maximum demand from 2008 to 2017. Conversely, water consumption at King County’s South Plant fluctuated over the last decade, with consumption increasing consistently from 2015 to 2017. According to plant staff, more water was used during that time because the water reuse facility was offline for repairs and upgrades. Now that the reuse facility’s upgrade is complete, the plant’s water use is predicted to drop closer to figures in 2015. As such, no growth is projected for King County’s South Plant. Nonetheless, to reflect King County’s South Plant’s varying water consumption, the Low scenario was assigned a starting demand close to 2015 levels, the Medium scenario was assigned a starting demand equal to the average annual demand from 2008 to 2017, and the High scenario was assigned a starting demand equal to the maximum demand experienced from 2008 to 2017. Since 2012, water sales to Skyway have increased steadily at a rate of eight percent annually. However, Skyway's most recent Comprehensive Water System Plan (2013) estimated an annual increase of 1.2 percent for the number of ERUs served by the City. Therefore, this range of growth is reflected in the annual growth rates set for each demand projection scenario. The Low scenario has a starting demand equal to Skyway’s historical average from 2008 to 2017 and a growth rate of 1.2 percent. The Medium and High scenarios have starting demands set to 202,000 gpd, representing Skyway’s maximum water purchase in 2017. The High scenario has an annual growth rate of 8 percent, while the Medium scenario has an annual growth rate of 5 percent, which is a midpoint between Skyway’s historical growth rates and growth rates predicted for the future. The City and Skyway will likely negotiate a new contract in the near future, which will include a cap on water sales (the existing agreement with Skyway can be found in Appendix D). The volume of this cap, however, is not known at the time of this Plan. For planning purposes, a cap of 300,000 gpd was set for all three demand projection scenarios.

To calculate the projected number of ERUs for the RWSA, the projected number of accounts shown in Table 3.15 were multiplied by the number of ERU per account shown in Table 3.8. Table 3.19 shows the ERU projections for each demand projection scenario. These ERU projections include ERUs that correspond to non-revenue water (DSL and Other Authorized Use), which were calculated by dividing the ADD projections of DSL and Other Authorized Use by the ERU values in gpd/ERU shown in Table 3.16. Section 3.5.4 below describes how ADD projections for DSL and Other Authorized Use were calculated. The number of ERUs served by the City is projected to increase from approximately 48,000 in 2019 to nearly 61,000 by 2039, an increase of 27 percent.

The ERU values for the Largest Consumers shown in this table were calculated by dividing the projected ADD by the ADD ERU value. Since the ADD ERU value is higher for the High Scenario than the Medium Scenario, the ERU values for the Largest Consumers in this table are shown as lower for the High Scenario than the Medium Scenario. 3.5.4 Average and Maximum Day Projections To calculate the ADD projections for each customer category, the ERU projections were multiplied by the ERU values in gpd/ERU unique to each demand projection scenario and customer category, as shown in Table 3.16. To establish total ADD projections, non-revenue water consumption, including Other Authorized Use and DSL, was added using Low, Medium, and High assumptions. Finally, for each demand projection scenario, MDD projections were established by multiplying ADD projections by the appropriate MDD to ADD peaking factor. CHAPTER 03 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 3-49 Table 3.20 shows ADD projections for Low, Medium, and High demand scenarios for each customer category, while Table 3.22 shows the same projections by pressure zone. Figure 3.18 shows a chart of the system-wide demand projections. The City's ADD is projected to be between 7.0 and 8.4 mgd in 2019, for the Low and High scenarios respectively. By 2039, ADD is estimated to be between 8.9 mgd and 10.8 mgd, for the Low and High scenarios respectively. The Medium scenario predicts 9.8 mgd. In 2039, MDD is estimated to be between 15.1 mgd and 21.5 mgd, for the Low and High scenarios respectively, as shown in Table 3.21. The Medium scenario predicts 17.7 mgd. Additionally, the Medium scenario predicts a 1.2 percent annual increase in water system demands, which equates to a 27 percent increase over the 20-year planning period. These demands are the basis for the water resource evaluation of Chapter 6 and the water system evaluation of Chapter 7. Table 3.23 shows these MDD projections by pressure zone. Appendix H shows detailed demand projections by year.

To plan its water system, the City selected three measurable WUE goals, which were incorporated into the demand projections: 1. Limit the peaking factor to less than 2.0. 2. Reduce DSL to 10 percent or less by 2022. 3. Maintain an ERU value under 160 gpd/ERU. These factors were used to develop the demand projections shown in Figure 3.17. As shown, the City's ADD is projected to be between 7.0 and 8.4 mgd in 2019, and between 8.9 mgd and 10.8 mgd by 2039. The Medium demand scenario predicts 9.8 mgd. By 2039, the City’s estimated MDD will be between 15.1 mgd and 21.5 mgd. The Medium demand scenario predicts 17.7 mgd. The Medium scenario also predicts a 1.2 percent increase in water system demands annually, which translates to a total increase in demand of 27 percent over the 20-year planning period. CHAPTER 04| WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 4-1 Chapter 4 WATER USE EFFICIENCY AND CONSERVATION PLAN In 2003, the Municipal Water Law (MWL), to address the increasing demand on Washington’s water resources. As part of this law, the state implemented the Water Use Efficiency (WUE) Rule, which requires all municipal water suppliers to use water more efficiently in exchange for guaranteed, flexible water rights to help meet future demands. The City of Renton (City) started a WUE program in 2007 to emphasize the importance of measuring water use and evaluating the rule's effectiveness. The intent was to minimize water withdrawals and use by implementing water-saving activities and adopting applicable policies, resolutions, ordinances, or bylaws. This chapter presents the City’s current and proposed actions to comply with conservation planning requirements and to promote using water efficiently. The chapter focuses specifically on the following four fundamental elements of the WUE program: 1. Planning requirements. 2. Distribution leakage standard. 3. Metering requirements. 4. Conservation planning and goal setting. This discussion follows the Washington State Department of Health (DOH) guidelines established in the WUE Guidebook, Third Edition (revised January 2017), which replaces the former Conservation Planning Requirements (March 1994). 4.1 Planning Requirements A municipal water system plan must include the following WUE elements: • Data collection. • Demand forecast. Both are described in greater detail below. 4.1.1 Data Collection The WUE Rule requires that all municipal water suppliers regularly collect production and consumption data. The City uses its source, intertie, purchase, and service water meters to collect system production and consumption data, which is summarized as monthly and annual totals. This planning document uses unique data, divided into the categories shown Table 4.1, to forecast future demand, describe water supply characteristics, help with decisions on water management, calculate distribution system leakage (DSL), and evaluate the WUE program. This information was ultimately compiled into the annual WUE report and submitted to the state. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 04 4-2 | MAY 2021 | FINAL Table 4.1 Categories of Data Collection Water Volume Entering Distribution System Water Produced (from City sources) Water Purchased (from SPU) Authorized Water Consumption - Metered Single-family Residential Multi-family Residential (including Duplexes) Industrial/Commercial/Government Irrigation Hydrants and Fire Wholesale Interties Regional Firefighting Training Center City Maintenance Use Tank/Reservoir Draining and Cleaning Authorized Water Consumption - Non-metered Firefighting King County South Plant Note: Abbreviation: SPU – Seattle Public Utilities. 4.1.2 Demand Forecast Demand forecasting estimates how much water will be needed in the future. To do this, forecasted demands were developed using demographic projections from the Puget Sound Regional Council (PSRC), all of which are detailed in Chapter 3 – Demand Projections. 4.2 Distribution System Leakage The WUE Rule requires the 3-year rolling average for DSL to be 10 percent or less. Table 4.2 shows annual DSL between 1988 and 2017. As the graph of the rolling 3-year average (Figure 4.1) shows, the DSL has generally been on a downward trend. However, the DSL has risen again in recent years, even though the City lowered its DSL below 10 percent in 2012 and 2013. To comply with the DSL standard, the City developed a Water Loss Control Action Plan (WLCAP) in 2008.The WLCAP was updated in 2018 and summarizes the City’s current and proposed water loss control efforts. The updated plan can be found in Appendix G. The leakage percentages in Table 4.2 may slightly differ from the ones reported to DOH. The City historically reported raw meter data to DOH. With the upgrade to AMI data, the City has been resolving data issues and the updated data is shown Table 4.2. In the future, the City will report water use data to DOH using the updated method.

CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 04 4-4 | MAY 2021 | FINAL Figure 4.1 DSL 3-Year Rolling Average 4.3 Metering As required by the MWL, all of the City’s sources of supply are metered via production meters. This includes all of the City-owned production wells, Springbrook Springs, interties with adjacent districts, and water purchased from SPU. The production meters are calibrated periodically. The City also provides service metering for all customers. The consumption meters are categorized either as large (3 inches or greater) or small (smaller than 3 inches). All large service meters are tested annually and repaired as needed. In 2012, the City implemented an Advanced Metering Infrastructure (AMI) system, which provides more time for water maintenance staff to perform repairs on small meters as well. With these measures in place, the City is in full compliance with the WUE metering requirements. 4.4 Conservation Planning To develop a successful WUE and conservation plan, the City must understand how, where, and when water is used. This knowledge reveals where savings and efficiencies can be made. The City had a total of 17,831 connections in 2017, most of which were residential connections. Commercial and Industrial sectors make up only about 6 percent of connections, yet account for 25 percent of overall consumption. This indicates that these sectors have opportunities for additional efficiency and conservation savings.

Summer irrigation season generally begins in May and extends through September. In 2017, the peak irrigation months of July and August experienced a 55 percent increase in average daily water consumption over annual average day demand (ADD). Although this result is typical, it shows that irrigation and general outdoor summer use could also have additional efficiency and conservation savings.

CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 04 4-6 | MAY 2021 | FINAL 4.4.1 Historic Conservation Program The City’s water conservation program was implemented in compliance with the Water Use Efficiency Act of 1989, which requires all public water systems to have a conservation program. After initiating its leak detection and repair program in 1989, the City observed a noticeable drop in volume of DSL. Since then, the conservation program has expanded to include school outreach, a speakers’ bureau, fairs, and promotion of regional programs. In addition, a 12-month water consumption history was added to water bills in 1992 to help customers understand their usage. In 1994, the City also began implementing tiered water-pricing rates to encourage consumer conservation. Table 4.4 summarizes past and current conservation efforts. Current measures are indicated with a “C” and have been in effect for the last 6 years. Measures that will continue through the next 10 years are indicated with a “P.” 4.4.1.1 Consumption History Figure 4.4 shows average water use per connection for the Single-Family Residential customer class between 1988 and 2017. During this period, Single-Family consumption per connection decreased steadily by approximately 30 percent. However, over the most recent decade (2008 to 2017), the decrease was less dramatic, with average Single-Family usage decreasing by 7 gallons per day (gpd), a 4 percent decrease. Figure 4.5 shows that total annual consumption has increased very little since 1988. However, annual consumption per connection, shown in Figure 4.6, has decreased by 32 percent. Various events and influences affected this downturn. One significant decline in water use occurred in 1993, which was largely attributable to the drought that occurred from 1992 to 1993 and to major regional education efforts to remediate the situation. This, coupled with the 1994 change in the City’s rate structure (with inverted-rate blocks), prevented water use from returning to pre-drought levels. In 2009, the City again instituted a more aggressive inverted-rate block structure for Single-Family and Duplex customers and changed Multi-Family and Irrigation rates. Rate increases in subsequent years have continued to encourage conservation and impact consumption. Although many factors contribute to the amount of water consumed, a consistent decline in water use over time indicates that water conservation measures and education do have a long-term impact.

The minimum number and type of efficiency measures a conservation program must evaluate or implement is based on the system’s total number of connections. With more than 17,000 connections, the City must implement five mandatory measures and must either implement or evaluate two additional measures. These mandatory measures are detailed in Table 4.5. The City must also evaluate or implement nine measures of its own choice. These selected measures are conducted either by the City or by the Saving Water Partnership (SWP), on behalf of the City. The City’s current conservation program was developed through a public process to support the City’s WUE goals. The original objectives and goals are being carried forward to this Plan with the goal of encouraging residents to actively and instinctively conserve water. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 04 4-10 | MAY 2021 | FINAL Table 4.5 WUE Mandatory Measures Must implement the following WUE measures: Status Install production (source) meters Implemented Install consumption (service) meters Implemented Perform meter calibration Implemented / ongoing Implement a WLCAP to control leakage if exceeds 10% Implemented / ongoing Educate customers about water efficiency at least once per year Implemented /ongoing Must evaluate or implement these WUE measures: Evaluate rates that encourage water demand efficiency Implemented Evaluate reclamation Implemented WUE Objectives As part of the initial WUE compliance, the City reviewed its water system and water usage and developed four objectives for its WUE plan: 1. Identify and reduce sources of DSL. 2. Ensure efficient water supply for continued growth in the service area. 3. Reduce peak day and peak season demands. 4. Maintain the historically low levels of customer water usage. WUE Goals The City has defined the following measurable goals: 1. Reduce DSL to 10 percent or less by 2022. 2. Limit the maximum daily demand (MDD) to ADD peaking factor to less than 2.0. 3. Maintain an equivalent residential unit (ERU) value under 160 gpd/ERU. As part of the SWP, the City also supports the regional 2019-2028 WUE goal to keep the total average annual retail water use of SWP members under 110 million gallons per day (mgd) through 2028 despite forecasted population growth by reducing per capita water use.” 4.4.2.2 Mandatory Measures Meters To fulfill all mandatory measures related to meters, the City installed AMI for both production and consumption meters. These meters are calibrated and/or tested periodically. Appendix G presents the City’s updated WLCAP. Reclamation In response to the Washington State Department of Ecology's water resource policy initiative and the DOH's 1994 Interim Conservation Guidelines, the City thoroughly evaluated the usage potential of its reclaimed water. This study, titled “City of Renton Conceptual Reuse Plan” (COR File Code WTR-09-0009), included a pilot project and long-range plan to develop a city-wide distribution system that would use reclaimed water for various uses. CHAPTER 04| WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 4-11 Then in 1995, King County, the City, and the City of Seattle Water Department published a study titled “Water Reclamation and Reuse: A Feasibility Study for the King County Metropolitan Area.” According to this study, the cost of reclaimed water service would be higher than the marginal cost of developing new potable supplies at that time under most conditions. A successful reuse project would have to serve a reasonably large demand (at least 1 mgd) and be located adjacent to a source of secondary treated effluent. The study also noted that the King County Renton Effluent Transfer System included a 96-inch pipeline in the Duwamish Corridor with 12 taps in place for reclamation and reuse. Therefore, site-specific reuse projects along the Duwamish Corridor were suggested as the most cost-effective and promising options (detailed in a King County report titled “An Economic Analysis of the North Seattle Reclaimed Water Project”). In 2011, the King County Wastewater Treatment Division began another engineering, environmental, and economic analysis of conceptual reclaimed water strategies. The City is now working with King County to provide them appropriate information for this analysis. Appendix I includes a completed King County Water Reclamation Evaluation Checklist for this use. The checklist identifies potential reclaimed water users from the City’s largest consumers. Education The mandatory requirement for annual customer WUE education is met through the City’s annual water quality report, also known as the consumer confidence report, or CCR. This report includes annual WUE data and water conservation education advice. City customers receive a postcard in the mail which provides a link to an electronic copy of the annual report (https://rentonwa.gov/city_hall/public_works/utility_systems/water_quality_report). Customers may also contact the Water Utility and request a hardcopy of the annual reports. Other customer education measures are part of the selected measures described below. Rate Structure A balanced water-rate structure is an important way to encourage water conservation. The City introduced a two-tiered inverted block rate pricing structure for single-family homes and duplexes in 1994. Then in 2009, the City reevaluated and instituted changes to its rate structure by defining rates for more customer classes, offering a more aggressive inverted-rate block structure for Single-Family and Duplex customers, and adjusting Multi-Family and Irrigation rates. Rate increases in subsequent years have continued to encourage conservation. Table 4.6 shows the City’s 2018 rate structure. Table 4.6 2018 Customer Class Rates Rate Structure (Cost per 100 cf) Single-family / Duplex 3-tier block rate ($2.54, $3.41 and $4.30) Multi-family $3.29 Non-residential $3.48 Irrigation $5.58 Irrigation (city accounts) $3.92 CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 04 4-12 | MAY 2021 | FINAL 4.4.3 Proposed Conservation Program Based on the number of the City’s connections, the WUE Rule requires the City to evaluate or implement at least nine measures of its choice that support the proposed goals, in addition to the mandatory measures described above. The nine selected measures are described below. The City’s conservation strategy has been to focus on the residential consumer, both indoor and outdoor, a strategy that has proved successful by continued savings. Most recently, emphasis has been on reducing summer peak usage, which is now a WUE goal. To lower peak consumption, the City has instituted a third tier and has increased irrigation rates. 4.4.3.1 Selected Measures 1 - Water Bill Consumption History Current customer bills provide historical data to help educate customers of their usage patterns throughout the year, particularly to see the impact of outdoor watering. With this information, they are encouraged to make informed conservation choices and to save money. 2 - School Outreach As part of the SWP, the City provides interactive educational experiences to Renton Elementary School students presented by Nature Vision. Presentations cover subjects such as Water Cycle Terrariums, Water Use Exploration, and more. The City also partners with other purveyors through the SWP to produce educational materials that explain the groundwater process and promote conservation. 3 - Utility Bill Inserts This avenue of communication is effective in delivering a focused message to customers. Once or twice per year, conservation information specifically geared toward residential customers is included with the utility bill. 4 - Natural Yard Care Workshops The City’s Water Utility department partners up with its solid waste and surface water departments to educate customers about water-efficient gardening and ways to reduce toxic chemicals in the yard and garden by hosting SWP gardening classes. 5 - Advertising and Public Outreach The City is a member of the regional SWP, the national Alliance for Water Efficiency, and the US Environmental Protection Agency’s WaterSense partnership. As a member, the City supports these organizations' missions to promote water efficiency and conservation through local, regional, and national advertising. 6 - City Demonstration Garden At the 200 Mill Avenue South building, the City maintains a demonstration garden that features low water and low maintenance plants. The garden presents an educational viewing of well-established plants that thrive in limited water and sloped conditions. 7 - Indoor Water Conservation Giveaways The City provides customers with free high efficiency showerheads and aerators as well as toilet leak kits. Distribution of these items also allows staff to discuss water conservation principles with residents and answer any related questions. CHAPTER 04| WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 4-13 8 - Hose Gaskets Replacement rubber hose gaskets are offered at community events such as Renton River Days, helping to reduce a source of common outdoor water waste. Although the annual savings cannot be qualified, the hose gaskets do contribute to summer peak reduction. 9 - Water Conservation Education Web Page The City’s water conservation web page provides information for indoor and outdoor savings and links to rebates and other resources. It also presents information for all age groups, including a “kids” page accessible to children and teachers. The City’s participation in the SWP offers access to a broad set of online conservation resources that are linked on the City’s web page. 4.4.3.2 Regional Conservation Participation To help achieve its stated WUE objective to “ensure efficient water supply for continued growth within its service area,” the City implemented long-range water supply planning. As part of this effort, the City evaluated alternate sources of water to meet the growing demand from the projected population growth and from development within the City's water service area. In 2010, the Water Utility evaluated alternatives for the City to obtain additional water supply from SPU and Cascade Water Alliance (CWA) and to improve water quality in Well PW-5A. The most cost-beneficial and reliable alternative was determined to be purchasing water from SPU; thus, a contract was negotiated between the City and SPU in 2011 (CAG-11-093). With this contract, the City became a part of the SWP, a consortium of water utilities with contracts with SPU. The SWP has created a collection of water conservation measures and technical assistance to City customers that took the City’s conservation program from one geared primarily toward residential customers to one that now includes owners/managers of apartments and condos as well as industrial and commercial customers. Table 4.7 presents the current SWP measures, rebates, and resources to be expected in 2019.

The City manages its water system in a manner that ensures public health and safety, meets all regulatory requirements, and protects environmental resources.” (Source: Renton Results – A Community Accountability Program) The policies, design criteria, and standards used in the Plan are based on laws and policies that originate from the following sources, listed in descending order, from those with the broadest authority to those with the narrowest: • Federal Regulations - Environmental Protection Agency. • Washington State Regulations - Department of Health and Department of Ecology. • King County Regulations. • City of Renton Ordinances - City Council. • City of Renton Administrative Policies – Mayor. • City of Renton Comprehensive Plan. • Department Policies - Public Works Department. • Water System Plan Utility Policies – Utility Systems Division/ Water Utility Staff. The City is committed to providing customers high-quality drinking water that is reliable, affordable, and meets strict safety standards. We strive to serve as responsible community stewards by upholding the City’s 2021-2026 Business Plan mission to provide a safe, healthy, and vibrant community by maintaining clean and sustainable drinking water services. The Plan includes policies, effective practices, and goals over time to improve the operation and management of the City’s water supply sources and water system toward sustainability, at a pace consistent with the current and future needs of the community. These goals have been applied to the planning process of the Water System Plan Update and will continued to be implemented in current and future programs and capital projects identified in the Plan. Law is set by the federal government through federal regulations, by the State of Washington (State) in the form of statutes: Revised Codes of Washington (RCW), Washington Administrative Code (WAC), by King County in the form of policies, and by Renton City Council (Council) in the form of ordinances and resolutions. City policies are established in order to provide a vision or mission of the Water Utility and to provide a framework for the planning, design, operation, management, and maintenance of the water system. City policies cannot be less stringent or in conflict with adopted laws. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 05 5-2 | MAY 2021 | FINAL 5.2 Service Area, Policies, and Standards The City manages its water utility and water system in accordance with established federal and state regulations for public water systems. City policies and standards set forth in this chapter provide a consistent framework for the planning, design, construction, maintenance, operation, and service of the City’s water system and water supply sources. The City has additional land use, development, and finance policies that specify additional requirements for new development or redevelopment projects that require water service for domestic, fire protection, and other uses. The City’s policies are grouped into the following major categories: • Service Area. • Water Supply Planning and Management. • Water Main Extension and Service Ownership. • System Reliability and Emergency Management Plan. • Fire Protection. • Financial. • Facilities. • Organization. 5.3 Summary of Policies for Water System Plan 5.3.1 Service Area 5.3.1.1 Mission Statement Ensure that the City’s drinking water supply is safe and sufficient and that the City’s infrastructure is adequate to meet our community’s present and future needs for water1. 5.3.1.2 Service Availability The City’s goal is to provide water service to all customers within the City’s retail service area (RSA) in a timely and reasonable manner consistent with applicable City policies, resolutions, ordinances, the Municipal Water Law, Washington State Department of Health (DOH) rules and guidelines, and applicable federal, state, and local laws and plans 2. The City shall serve an applicant for new service within its retail service area if all of the following conditions are met. 1. The service request is consistent with adopted local plans and development regulations. 2. The water system has sufficient water rights to provide service. 3. The water system has sufficient capacity to serve water in a safe and reliable manner. 4. The water system can provide service in a timely and reasonable manner. 5.3.1.3 Government Consistency Provisions of water service should be consistent with the goals, objectives, and policies of this Plan and the Renton Comprehensive Plan. This Plan will be consistent with local, county, and 1 Sources: Renton Comprehensive Plan Goal U-N, Outcome Management for Water Utility Service Delivery Plan. 2 Sources: WAC-246-290, Municipal Water Law, Renton Comprehensive Plan, Water System Plan. CHAPTER 05 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 5-3 state land use authorities and plans. Water service should be consistent with the growth and development concepts directed by the City’s Comprehensive Plan 3. 5.3.1.4 Existing Water Service Area and Retail Service Area The City’s RSA (Figure 1.3 in Chapter 1) encompasses the area where the City has existing distribution mains or where distribution mains can be extended in a reasonable timeframe 4. The City’s retail service area is established in accordance with the East King County Coordinated Water System Plan and the Skyway Coordinated Water System Plan. The City also has inter-local agreements with neighboring cities and water districts to address minor adjustments of service area boundaries. In general, the City’s RSA area is located within incorporated City of Renton with the exception of several very small areas within unincorporated King County. The City uses its existing service area agreements to determine areas where water service will be provided. Therefore, annexations to the City do not affect the provisions of water service. The City’s water service area encompasses the retail service area, the portion of the Skyway Water and Sewer District that is served by City of Renton water through a wholesale agreement, and the future service area described in the next section. The City’s water service area is shown in Figure 1.3 of Chapter 1. 5.3.1.5 Future Service Area The only potential changes to the City’s RSA is for a small area near the westerly City limits. This area is currently served by Seattle Public Utilities (SPU) and may be served by the City in the future upon annexation. The future annexation area to be served by the City is also described in Skyway Water & Sewer District Comprehensive Plan and in the Skyway Coordinated Water System Plan. 5.3.1.6 Potential Annexation Areas The City’s potential annexation areas (PAA) boundary extends beyond the City’s city limits and water service area boundary. Other water purveyors serve areas outside of the City’s water service area. Due in large part to the geography of the City, it is unlikely that its water service area would be extended further beyond the existing water service area. Any new areas within the City’s PAA that are annexed by the City would likely continue to be served by the other utilities currently serving them 5. 5.3.1.7 Satellite/Remote Systems The City does not allow satellite/remote systems. 5.3.1.8 Service for Annexations without Existing Municipal Water Supplies The City intends to provide water service to areas annexed to the City that do not have existing water service from other municipal water suppliers and water districts. Service extension by the City may be considered under such conditions only if the City’s costs are recovered and sufficient financial resource is available and that service to annexations will not decrease the level of service to existing customers or increase the cost of service to existing customers 6. 3 Sources: WAC-246-290, Renton Comprehensive Plan Policy U-1, Water System Plan. 4 Sources: WAC-246-290, East King County Coordinated Water System Plan, Skyway Coordinated Water System Plan, Water System Plan. 5 Source: Renton Comprehensive Plan, Water System Plan. 6 Source: Renton Comprehensive Plan Policy U-5, Water System Plan. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 05 5-4 | MAY 2021 | FINAL 5.3.1.9 Service for Annexations with Existing Municipal Water Supplies The City will not provide water service to areas annexed to the City that are already served by other existing municipal water suppliers or water districts. Areas annexed with existing municipal supply must meet the City water utility standards 7. 5.3.1.10 Service for Protection of Public Health The City will allow extension of water service without annexation to areas outside of the City limits when such areas are within the City’s water service area, or when no other reasonable service is available, and it is determined by the City and/or by DOH that a public health emergency exists or is imminent 8. 5.3.1.11 Conditions for Service to Properties with Existing Private and or Exempt Wells The City will provide water service for domestic and for fire protection to properties within the City water service area that have existing private wells and/or exempt wells subject to the following conditions: 1. All “exempt” wells and private wells on the property must be decommissioned in accordance with Washington State Department of Ecology (DOE) standards and regulations, except when such wells can be used by the City for purposes including but not limited to: water supply, water supply mitigation, resource protection, environmental monitoring, or remediation of contamination. 2. All water rights, permits, or certificates must be deeded to the City if the type of use is municipal, community, or domestic. Any associated source(s) must either be decommissioned or deeded to the City, at the discretion of the City. Water rights, permits or certificates, for which the type of use is irrigation, industrial, or agricultural may be retained if the proposed land use is consistent with the type of use listed on the water right. If the proposed land use is not consistent with the type of use listed on the water right, then the water right must be deeded to the City; and any associated source(s) must either be decommissioned or deeded to the City, at the discretion of the City. 5.3.1.12 Requests for Assumption by Water Districts or Private Water Systems The City may assume the operation of a water district or private water system at their request if the following conditions are met and subject to the approval of the Council 9: 1. The district or private system is adjacent to or within the City’s water service area. 2. The district’s or private system’s facilities meet the City’s performance criteria and engineering standards, or a plan is in place to assure that they will be brought up to Renton’s standards without adversely impacting the City’s existing customers financially or with regard to level of service. 3. The assumption of the district or private system is permitted by State law. 4. The City shall require that the district or private system to transfer the ownership of its water supply sources and associated water rights to the City. Water rights must be 7 Source: Water System Plan. 8 Source: RCW, Water System Plan. 9 Source: RCW, WAC, Water System Plan. CHAPTER 05 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 5-5 successfully transferred to the City and approved for municipal water use by the DOE prior to commitment from the City for water service. 5.3.1.13 City Initiated Assumption of Water Districts or Private Water Systems The City will seek to assume the operation of a water district when the Council determines that the assumption is in the best interest of the City and the assumption is consistent with the City’s Comprehensive Plan. The City will follow State laws and guidelines in assuming portions of adjacent water systems as a result of annexations 10. 5.3.1.14 Wholesaling Water The City will continue to provide wholesale water to Skyway Water and Sewer District through a single metered connection in accordance to the current wholesale water supply agreement between the City and the District. The City is not planning to provide additional water to the District above the quantity identified in the existing wholesale agreement. The City has no plans to sell water wholesale on a long-term basis to any other purveyor. Sales of water for short term basis will be evaluated on a case by case basis. Current service agreements are included in Appendix D. 5.3.1.15 Wheeling Water The City does not currently wheel water. Water chemistry compatibility and its effects on water quality, including aesthetics such as taste and odor would be a primary consideration. The City will evaluate any request for wheeling water on a case by case basis. 5.3.1.16 Water Service to Properties in King County and within Renton Retail Service Area As a result of numerous annexations to the City up to 2018, there is one developed area that is within the City’s RSA and within unincorporated King County, which could be served by the City. The City currently serves three areas outside of its RSA: Skyway area, Cedar Rim Apartments in Newcastle, and the commercial area in Tukwila near 17900 West Valley Hwy. For these areas the City has adequate existing infrastructure and is providing water service to all existing residences within this area known as the Sierra Heights Division 3 and 4 and the Western Hills subdivisions. For any new development or redevelopment projects within the above unincorporated King County and within the City’s RSA, the City intends to provide “timely and reasonable water service” consistent with State Law RCW 19.27.097. For all new development and redevelopment projects and building permit applications requiring a “King County Certificate of Water Availability”, the City typically processes and issues the requests for water availability within one week of our receipt of the applicants’ written requests. Developers’ extensions of water mains will be required to provide water service for domestic and for fire protection to all new development and redevelopment projects. The City typically reviews the civil plans for water main extensions within 3 weeks of our receipt of the plans and the plans are approved as soon as our review comments have been addressed. The City also coordinates with King County to assure that all county road permits are obtained and that all fees are paid to the county for plan review and for inspection of the roadway restoration related to the construction of the water lines within the county roads. 10 Source: RCW, WAC, Council Discretion, Renton Comprehensive. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 05 5-6 | MAY 2021 | FINAL The City charges a higher water commodity rate to customers that are outside of the City limits and within the City’s RSA, at 1.5 times the inside City Limit water rate 11. The higher rate is necessary for the City to recover additional costs incurred for obtaining King County right-of-way permits for the installation, maintenance, repair of water mains, water service lines, hydrants and related appurtenances within the county roads. The City must also relocate its water mains at its own cost, when directed by King County under franchise agreement to accommodate future County roadway improvement work and the roadway overlay program. 5.3.2 Water Supply Planning and Management Policies 5.3.2.1 Water Supply Planning It is the City’s goal to have system-wide reliable supply sources, treatment, pumping and storage facilities to meet the current and projected maximum daily demand (MDD) – with the largest source out of service 12. The City will work cooperatively with adjacent purveyors to assure reliable water supply at the lowest environmental and economic cost. The City will pursue additional and/or new water supply and use water conservation, water use efficiency (WUE) measures and water reuse programs to ensure adequate water supply needs to meet the essential needs of the community and water demand created by growth targets established through the Growth Management Act (GMA) planning process. Adequate supply is enough water to meet normal peak day demands of the City’s customers. Peak day demand includes the effects of drought and curtailment. As time passes, normal demand is expected to decrease on a per household basis for two reasons. First, average household size is expected to decline, reducing the number of water users per house. Second, continued efforts to use water wisely by all customers will reduce demand. The City intends to take a cautious approach toward demand reductions that result from behavioral changes, which will not be considered permanent. Alternately, structural improvements (e.g., low-flush toilets, low-flow shower heads, or other water-saving devices) will be considered permanent reductions in demand. The City supports efficient use of water. The City supports eliminating the “waste” of water 13. The City has adopted rates to achieve these objectives. The quantity of water at the source shall: (1) be adequate to meet the maximum projected water demand of the RSA as shown by calculations based on the extreme drought of record; (2) provide a reasonable surplus for anticipated growth; (3) be adequate to compensate for all losses such as silting, evaporation, seepage, etc.; and (4) be adequate to provide ample water for other legal users of the source14. 5.3.2.2 Regional Water Supply Planning The City will participate in regional water supply management and planning activities. The City will monitor legislative, regulatory, litigation, and planning activities that may impact or influence the adequacy or reliability of supply 15. 11 Source: City Ordinance 4461, Renton Municipal Code 8-4-32(A). 12 Source: WAC 246-290-222, Renton Comprehensive Plan Goal U-C and Policy U-11. 13 Sources: City Ordinance 1437, Renton Municipal Code 8-4-23, Renton Comprehensive Plan Policies U-6 and U-8. 14 Sources: WAC 246-290-420, WAC 246-290-200, RCW 19.27.097, RCW 58.17.110, Renton Comprehensive Plan Policies U-9 and U-10, Water System Plan. 15 Source: Council and Administration Discretion. CHAPTER 05 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 5-7 5.3.2.3 Water Supply and Resources Management The City will practice and support water resource management that achieves a maximum net benefit for all citizens and promotes enhancement of the natural environment 16. The City operates and monitors its water supply sources to ensure compliance with all conditions and withdrawal quantities limits for total annual withdrawal quantity and for instantaneous withdrawal quantity, established under State issued water rights certificates and permits17. The City will continue to monitor the pumping of its wells to allow aquifer recovery and to avoid impacts to in-stream flows for the Cedar River. The City has installed flow control/throttling valves and flow metering equipment on its well pumps to monitor instantaneous pumping rates and total pumping rates. The controls are set up so that the well pumps cannot exceed their individual and total instantaneous flow rates established under the water rights certificates and permits issued by the DOE. If the demand calls for additional water, the controls are set up so that the City will receive additional water through the intertie with SPU’s 60-inch Bow Lake pipeline, and if needed through two other interties with SPU at Tiffany Park and Fred Nelson pump stations 18. 5.3.2.4 Reclaimed Water Use The City will support the regional supplier’s study of reclaimed water use opportunities and will work with King County Department of Natural Resources to identify potential reclaimed water users and demand. Any reclaimed water to be used as a source of supply should only be provided through regional water suppliers. The City has identified several potential users of reclaimed water for landscape irrigation uses, including the Boeing Longacres facilities 19. 5.3.2.5 Conservation and Water Use Efficiency The City will actively continue to promote voluntary conservation and the wise use of water and implement a water conservation program and measures consistent with the requirements of the DOH. The City will cooperate with SPU to regional conservation goals 20. The City has implemented a water rate structures promoting conservation such as, residential inverted block rate and higher commodity rate for commercial and multifamily irrigation. In 2015, the City completed the deployment of an Advanced Metering Infrastructure (AMI) system, which enhances the City’s water conservation activities and optimizes the pumping of its water supply wells 21. The City has adopted the following WUE goals: • Reduce distribution system leakage to 10 percent or less by 2022. • Limit the MDD to average day demand (ADD) peaking factor to less than 2.0. • Maintain an equivalent residential unit (ERU) value under 160 gallons per day (gpd) per ERU. 16 Source: Renton Comprehensive Plan Policy U-16. 17 Source: Renton Comprehensive Plan Policy U-11. 18 Source: Municipal Water Law, Water System Plan, Water Rights Certificates and Permits. 19 Source: Municipal Water Law, Water System Plan. 20 Source: Renton Comprehensive Plan Policy U-17. 21 Source: WAC 246-290, Water System Plan, WUE Goals. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 05 5-8 | MAY 2021 | FINAL 5.3.2.6 Water Shortage Response Plan The City maintains and updates a local response plan in case of a water supply shortage caused by a drought or supply interruption. The City will implement necessary water conservation measures to avoid curtailment in all but the most exceptional circumstances. The Mayor and/or Council are empowered to declare an emergency and to carry out the necessary actions to ensure compliance with the Water Shortage Response Plan 22. 5.3.2.7 Emergency Interties The City has emergency interties with adjacent water systems for short-term emergency uses. The City will evaluate requests for emergency interties on a case by case basis and shall support emergency interties with adjacent systems if they benefit both providers and if they don’t compromise the City’s ability to serve its existing customers or its future supply needs. 5.3.2.8 Water Quality The City shall operate and manage the system to provide water quality that meets or exceeds all health requirements. The City will take steps to meet or exceed all water quality laws and standards. The City will take all reasonable measures to ensure that water reaching the point of delivery, the customer’s meter, meets all water quality standards. The City shall continue to maintain and upgrade its system to provide the best water quality and service 23. The City shall submit Monthly Water Quality Reports to DOH. 5.3.2.9 Cross Connection Control The City shall administer a cross connection control program that protects the City’s public water supply and users of the public water supply from backflow contamination in accordance with State law and to the DOH regulations and guidelines. The City has an established cross connection control program and related ordinances and procedures to implement the program. The City shall submit an Annual Summary Report to the DOH 24. 5.3.2.10 Wellhead Protection Program In conjunction with Plan development, the City updated its Wellhead Protection Plan that will be reviewed by the DOH along with this Plan. Updates of the plan are described in Appendix J of this Plan. The Wellhead Protection Plan will be reviewed and updated, if necessary, in conjunction with the Plan update. 5.3.2.11 Aquifer Protection Program In 1998, the City established an Aquifer Protection Program and adopted ordinances, policies, standards, and regulations for existing and new development within the City’s aquifer protection areas (APAs) to protect the aquifers from potential contamination by hazardous materials 25. The City shall continue to provide outreach and training to facilities within the APAs. The City is in the process of updating the program: 1) update APA zones to reflect our capture zone delineations, 2) will be performing site surveys at facilities within the APA zones that store/use hazardous materials, 3) provide outreach and training for aquifer protection.” 22 Source: WAC 246-290, Water System Plan. 23 Sources: USEPA, Safe Drinking Water Act, Council Discretion, WAC 246-290-310, WAC 246-290-135.

As-built plans, easements and bill of sales shall be provided to the City for the conveyance of the water mains, hydrants, water meters, and related appurtenances. 5.3.3.12 Latecomer Agreements The City has discretionary power to grant latecomer’s agreements to owners and developers for pro rata portion of the original costs of water main extensions. The authority to approve a latecomer’s agreement is vested in the Council. The latecomer’s agreement can be granted for a period up to but not exceeding 15 years and no term extension will be granted 36. 5.3.4 System Reliability and Emergency Management Plan 5.3.4.1 Service Reliability The City has built in redundancies in the operation and in the construction of capital improvements of its water system, including reservoirs, pumps, pressure reducing stations, and transmission and distribution mains, to maintain service reliability. The City has water system interties with SPU and emergency interties with neighboring water purveyors to provide water service during emergencies. All new water facilities added to the system that require electrical power shall be provided with backup emergency electrical power with automatic start and automatic transfer to and from commercial power. The power source may be an electrical generator or storage batteries. Existing facilities requiring electrical power that do not have on-site emergency electrical power with auto-start / auto transfer shall have such capabilities added as part of the Capital Improvement Plan (CIP) within the next 10 years. Emergency backup power for sources and booster pump stations (BPSs) shall be capable of operating at full load without being refueled for at least 36 hours. Battery backup power for Supervisory Control and Data Acquisition (SCADA) Remote Telemetry Units (RTUs) and Master Telemetry Units (MTUs) shall be capable of providing power for at least 8 hours of continuous operation without needing a recharge or replacement. Wells and BPSs that do not have emergency power with automatic start and automatic transfer to and from commercial power are not considered reliable, because they cannot be relied upon to provide water during a fire. If at some time in the future installed storage is adequate to meet fire flow demands, then this policy could change. Each BPS shall be equipped with redundant, reliable pumps so as to meet the MDD with only reliable pumps and the largest pump serving the pressure zone out of service 37. 35 Sources: Municipal Water Law, City Ordinances, City Development Regulations, Water System Plan. 36 Sources: City Ordinance 4443, Renton Municipal Code 9-5. 37 Sources: WAC 246-290-420, DOH Water System Design Manual, Council Discretion, Water System Plan. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 05 5-12 | MAY 2021 | FINAL 5.3.4.2 Emergency Preparedness The City has an adopted Comprehensive Emergency Management and Hazard Mitigation Plan developed in accordance with Federal Emergency Management Agency (FEMA) standards, to address issues related to continuity of water service, long-term system recovery and to ensure the orderly and full restoration of the water system after an emergency. The City is continually updating its Water System Emergency Response Plan as part of its operations program, and as new facilities are brought into operation. 5.3.4.3 Vulnerability Assessment The City has completed a Security Vulnerability Assessment of its water system in compliance with the Public Health Security and Bioterrorism Preparedness Act of 2002 as directed by United States Environmental Protection Agency (USEPA). The City has phased in the design and construction of the recommended security upgrades as part of the CIP 38. 5.3.4.4 Multiple Sources of Supply The City will develop supplies that, when combined, meet the DOH demand criteria. The City will maintain and execute data collection strategies and record keeping procedures that quantify the average day and peak day demands of each customer class. The City will develop reliable supplies that meet the anticipated MDD (based on customer demand patterns, weather, and growth) with the largest of the supply sources not included 39. 5.3.5 Fire Protection Policies 5.3.5.1 Fire Protection Responsibility The City shall continue to maintain and upgrade its water system infrastructure to deliver adequate water for fire protection to all residential, commercial, industrial customers, schools and other public facilities served with City water 40. The City shall continue to perform routine maintenance on all of its fire hydrants and valves to keep them in working order. The City shall continue to replace its old and undersized water mains with adequate size mains to provide the required level of fire protection. 5.3.5.2 Fire Flow Requirements for New Construction New development, redevelopment, subdivisions, and tenant improvements projects within the City will be required to provide the minimum fire flow requirements as established by Renton RFA. It is the developer’s responsibility to install, at its own cost, all water system facilities including off-site and on-site main line extensions and upgrades to meet the required fire flow demand and applicable City’s development regulations and standards. If the off-site improvements result in regional benefit, the developer may request the City to cost participate in the construction of the improvements. If the off-site improvements benefit other adjacent properties, the developer may request a latecomer agreement to recoup equitable costs from future development of properties within the latecomer boundary which can benefit from the improvements. 38 Source: WAC 246-290-221, -222, -230 & -235, DOH Water System Design Manual. 39 Source: RCW 90.54.180, 90.42.005, WAC 246-290-420, Comprehensive Plan Policy U-11, Water System Plan. 40 Source: Renton Comprehensive Plan Policy U-12. CHAPTER 05 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 5-13 5.3.5.3 Fire Flow Requirements for Existing Construction Existing structures are not required to upgrade the City’s water system infrastructure to meet current fire flow and development standards. Redevelopment of existing structures, including remodeling, expansions, additions, change of occupancy and use can trigger the requirements for upgrades to the water system. The City is not obligated to upgrade existing system to meet current codes. As part of its CIP the City continues to systematically replace its old and undersized water mains to bring them to current standards with a goal to provide a minimum fire flow of 1,000 gpm (at 20 psi residual pressure), and to install fire hydrants at 500 feet spacing, throughout the distribution system. 5.3.5.4 Fire Flow Quantity The minimum fire flow requirements for one- and two-family dwellings having a fire flow calculation area that does not exceed 3,600 square-feet shall be 1,000 gpm for 1 hour at 20 psi residual pressure. Fire flow requirements for one- and two-family dwellings larger than 3,600 square-feet shall be at least 1,500 gpm for 2 hours and shall be determined by the Renton RFA 41. The baseline fire flow requirement for multi-family, commercial, and industrial buildings is 3,000 gpm for 3 hours. Fire flow quantities and fire flow durations above this baseline shall be determined by the Renton RFA. 5.3.5.5 Fire Flow Storage The City’s fire flow storage policies are described in the Facilities Policies Section 5.3.7. 5.3.5.6 Fire Hydrants All fire hydrants shall be equipped with Storz adapters on the pumper ports. All fire hydrant feed lines shall be equipped with gate valves (foot valves). The minimum size of feed lines to fire hydrants shall be 6-inch diameter. Fire hydrant lines over 50 feet long shall be 8-inch diameter. 5.3.6 Financial Policies 5.3.6.1 Fiscal Stewardship The Water Utility will follow financial policies and criteria adopted by the Council. Water Utility funds and resources shall be managed in accordance with applicable laws, standards, City financial and fiscal practices and policies. The financial criteria include rate stabilization, establishment of fund balance and operating reserves, maintaining the desired debt service coverage. 5.3.6.2 Enterprise Fund – Self-Sufficient Funding The Water Utility shall be operated as a self-supporting enterprise fund. Revenues to the Water Utility primarily come from customer charges from water sales, system development charges, plan review and inspection fees. Detailed information on the City’s financial program are presented in Chapter 10 42. 41 Sources: Renton Municipal Code 4-5-070(C), International Fire Code Appendix B. 42 Source: Council Discretion, Water System Plan. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 05 5-14 | MAY 2021 | FINAL 5.3.6.3 Rate Stabilization The City’s financial goal is to minimize and stabilize the long-term, life-cycle cost of service. Rates and additional charges shall be cost-based to recover current, historical, and future costs associated with the City’s water system and services 43. 5.3.6.4 Operating Reserve An operating reserve provides a liquidity cushion. It protects the financial viability of the utilities from the risk of short-term variation in revenues and expenses – primarily caused by seasonable fluctuations in billing, unanticipated operating expenses or lower than expected revenue collections. Target funding levels are generally expressed in number of days’ operating and maintenance (O&M) with the minimum requirement varying with the expected risk of unanticipated needs or revenue volatility. Industry practice ranges from 30 days to 120 days of O&M. The City’s goal (used in the financial analysis – see Chapter 10) is to stabilize the Water Utility funds and maintain an operating reservoir of 24 percent annual operating expenses for operation of the water system for 90 days. This is also consistent with the City’s latest rate study. 5.3.6.5 Debt Service The City’s goal is to maintain a desired reserve for debt service coverage of 1.25 times the annual financial obligations 44. 5.3.6.6 Bonds vs. Cash Expenditures • All non-CIP shall be paid for by rates. • All system reinvestment, maintenance, replacement and rehabilitation projects shall be paid for by rates. • CIP projects for new infrastructure to accommodate growth or to increase system capacity can be paid for using bonds 45. 5.3.6.7 Comprehensive Planning Comprehensive plans for water systems should be updated every 10 years, using a 20-year or greater planning horizon, as required by State law and financial policies shall be reviewed and updated as needed. The City has a 6-year CIP which is updated with each biennial budget cycle. 5.3.6.8 Equitable Rates The City’s rates and charges shall be equitable to recover costs from customers commensurate with the benefits they receive and to provide an adequate and stable source of funds to cover the current and future cash needs of the City Water Utility. Rates shall be developed using the cash basis to determine the total revenue requirements of the Water Utility. Rates should be calculated for the service area as a whole46. 5.3.6.9 Outside-City Rates For customers residing outside the city limits, water rates are 1.5 times the residential city rates47. 43 Source: Council Discretion. 44 Source: Council Discretion. 45 Source: Council Discretion. 46 Source: Council Discretion, Water System Plan. 47 Sources: Council Discretion, City Ordinance 4461, Renton Municipal code 8-4-32(A). CHAPTER 05 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 5-15 5.3.6.10 Discounted Rates The City shall provide a senior and/or disabled citizen discount on City water rates 48. 5.3.6.11 Other Fees and Charges Owners of properties that have not been assessed or charged an equitable share of the cost of the City’s water system shall pay, prior to connection to the system, one or more of five charges: 1. System development charge. 2. Special assessment charge. 3. Latecomer's fees. 4. Inspection/approval fees. 5. Water meter installation fees 49. 5.3.6.12 Ancillary Charges Customers should be charged for supplemental, special purpose services through separate ancillary charges based on the cost to provide the service. Ancillary charges create more equitable fees and increase operating efficiency for services to customers. Revenue from ancillary charges should be used to offset operations and maintenance costs 50. 5.3.6.13 Inflation Rate The inflation rate should be based on information provided by the Finance Department. 5.3.7 Facilities Policies 5.3.7.1 System Pressure The existing facilities will be operated and new facilities constructed to ensure compliance with DOH and Insurance Services Organization (ISO) criteria for maximum and minimum pressure. The City will provide the minimum water pressure requirement established by DOH at 30 psi at the service meter during MDD and during peak hour demand conditions, not including a fire or emergency. The City’s goal is to provide a minimum of 40 psi at the highest domestic water plumbing fixture or at the highest fire sprinkler head, except during emergency conditions. The City’s goal is also to provide a maximum of 110 psi at the service meter to prevent over pressurization of water uses fixtures and appliances. Current building codes require the installation of individual pressure reducing valves (PRVs) by property owners beyond the water meter where system pressures exceed 80 psi. During a failure of any part of the system, the maximum pressure shall not exceed the normal pressure rating of the pipe, generally 150 psi 51. 48 Sources: Council Discretion, Renton Municipal Code 8-4-31(C). 49 Source: City Development Regulations. 50 Sources: Council Discretion, Water System Plan. 51 Source: WAC 246-290-230, Insurance Services Organization (ISO), Council Discretion, Water System Plan. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 05 5-16 | MAY 2021 | FINAL 5.3.7.2 Velocity The existing facilities will be operated and new facilities constructed to minimize damage from excessive pipeline velocities. When adding to the distribution system or replacing components of the distribution system, water mains shall be sized such that: • Under normal conditions, the velocity of water in a transmission main shall be less than 4 fps during demand periods. • Under emergency conditions, such as a fire, the velocity of water in a transmission main shall be less than 8 fps. Fire flow planning and modeling will use a de-rating procedure that limits fire flow velocities to 8 fps 52. 5.3.7.3 Storage The existing storage facilities will be operated and new storage facilities constructed to comply with DOH criteria and good engineering practice. Storage within the distribution system must be of sufficient capacity to supplement transmission supply when peaking demands are greater than the source pumping capacity (equalizing storage) and still maintain sufficient storage for a fire or other emergency condition. Equalizing, fire suppression, and stand-by storage are provided in addition to operational storage. Location of storage facilities should be in areas where they will satisfy the following requirements: • Minimize fluctuations in system pressure during normal demands. • Maximize use of the storage facilities during fires and peak demands. • Improve the reliability of the supply for the water system 53. Equalizing Storage The bottom of the equalizing storage component must be located at an elevation which produces no less than 30 psi at all service connections throughout the pressure zone under peak hour demand conditions, assuming all sources are in service. Equalizing storage requirements shall be determined using the following equation: ES = 150 min x (PHD – MDD) Where ES is equalizing storage volume. PHD is peak hour demand and is calculated based on maximum day diurnal curves developed for each operational area, and MDD is maximum day demand. The analysis shall compare the cost of designing and constructing storage versus the cost of purchasing wholesale water from SPU, including the cost of upgrading and / or adding intertie connections to the SPU transmission mains. Fire Suppression Storage For fire flow supplied via gravity storage, the bottom of the fire suppression storage component shall be located at an elevation which produces no less than 20 psi at ground level at all points in 52 Source: DOH Water System Design Manual, Renton RFA, ISO, Council Discretion, Water System Plan. 53 Source: WAC 246-290-235, Council Discretion, Water System Plan, Renton RFA. CHAPTER 05 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 5-17 the zone under peak hour demand condition, assuming the largest source or booster pump to the zone is out of service. The fire suppression storage criteria available from the ISO were considered in the study. The quantity of fire flow storage provided will approach these requirements as closely as possible, considering economic factors and other design criteria. Sufficient storage for a fire condition is the product of the fire protection water demand and the required duration as determined by Renton RFA. Standby Storage The stand-by storage component or the fire suppression storage component, whichever volume is smaller, can be excluded from the zone’s total storage requirement (also known as “nested” storage) provided that the elevation of the bottom of effective storage is no less than that elevation which produces 20 psi at the meter at all points in the zone under peak hour demand conditions, assuming the largest source or booster pump to the zone is out of service. The calculation of the standby storage volume requirements shall use the following equation: SS = 200 gallons/ERU Where SS is standby storage volume ERU is the number of equivalent residential units in the zone 5.3.7.4 Pipelines and Water Services New water transmission and distribution pipelines and facilities shall be designed and constructed to comply with DOH criteria, American Water Works Association (AWWA) standards, the City’s latest design criteria, and good engineering practice. Where possible, transmission and distribution mains shall be looped to increase reliability and decrease head losses. The preferred pipe material for distribution mains is ductile iron. In residential areas, the grid of distribution mains shall consist of ductile iron mains at least 8 inches in diameter. In commercial, industrial, Central Business District, and other areas with high fire flow demand, the grid of the distribution system shall consist of 12-inch or larger ductile iron mains. All 6-inch and smaller dead-end mains shall terminate with a blow-off assembly. All 8-inch and larger mains shall terminate with a fire hydrant. Distribution system design assumes that only adequately sized service lines will be used. All residential service lines will be copper and 1-inch or larger in diameter. The meter shall be minimum 3/4-inch by 5/8-inch with adapters to fit a 1-inch meter setter. In all other cases, the service line from the main line to the meter shall be the same size as the meter. All water service lines shall conform to the plumbing code. Connections to the system shall comply with the City’s cross connection control standards (Appendix L). In general, the standard protection for commercial and industrial connections is the use of reduced pressure backflow assemblies (RPBAs). CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 05 5-18 | MAY 2021 | FINAL Valve installations shall meet the following criteria: • Zone valves shall be located at all pressure zone interfaces to allow future pressure zone re-alignment without the need for additional pipe construction. • Isolation valves shall be located wherever necessary to allow individual pipelines to be shut down for repair or installing services. Four valves shall be provided per cross, and three valves per tee. • Isolation valves should be spaced along water mains at intervals not to exceed 400 feet. • Air/vacuum release valves shall be placed at all high points or “crowns” in all pipelines. • Individual PRVs are recommended where the service connection pressure exceeds 80 psi, in accordance with the UPC. Individual PRVs must be installed on the customer’s property downstream of the water meter and the customer is responsible for the proper operation and maintenance of the PRV. The PRVs protect customers from high pressures in the case of failure of a pressure-reducing station. • Check valves are recommended for all service lines in the City. Check valves prevent hot water tanks from emptying into the transmission main when the main is empty and prevent contamination of the system mains due to possible cross connections in the customer’s service. Meter setters equipped with check valves are required by the City on all new customer service lines. 5.3.7.5 Booster Pump Stations The existing booster facilities will be operated and new booster facilities constructed to comply with DOH criteria and good engineering practice. All existing and future booster stations should be modified/constructed to comply with the following minimum standards: • All structures should be non-combustible, where practical. • All buildings should have adequate heating, cooling, ventilation, insulation, lighting, and workspaces necessary for on-site operation and repair. • Underground vaults should be avoided where possible due to the increased potential of flooding, electrocution, and other hazards. • Sites should be fenced to reduce vandalism and City liability where appropriate. • Each station shall be equipped with a flow meter and all necessary instrumentation to assist personnel in operating and troubleshooting the facility. Emergency power capability (auto-start/auto-transfer) shall be provided to each BPS. Booster stations should be placed wherever necessary to fulfill the following criteria: • Provide supply redundancy to a pressure zone. • Improve the hydraulic characteristics of a pressure zone. • Reduce the cost of water supply. • Improve water quality (i.e., increase circulation)54. 5.3.7.6 Pressure Reducing Stations The existing PRV facilities will be operated and new PRV facilities constructed to comply with DOH criteria and good engineering practices. 54 Source: WAC 246-290-200, DOH Water System Design Manual, Water System Plan. CHAPTER 05 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 5-19 All PRVs should be placed in vaults that are large enough to provide ample work space for field inspection and repair of the valves. Vaults should be tall enough to allow operating personnel to stand erect. Vaults should drain to daylight or be equipped with sump pumps to prevent vault flooding. Each PRV station shall have a larger main (lead) PRV for fire flow demand and a smaller (lag) PRV for anticipated domestic demand. The smaller (lag) PRV shall have a meter connected to the telemetry/SCADA system. Pressure-relief valves should be provided on the low-pressure side of the PRV to prevent system over-pressuring in case of a valve failure. High-pressure alarms should be transmitted to the central control cabinet to alert operating personnel of the PRV failure. When pressure at the service line connection point is such that the plumbing code dictates that water service requires a PRV (e.g., 80 psi) the customer is required to install, own, operate and maintain the PRV. The PRV shall be installed on the customer side of the water service 55. 5.3.7.7 SCADA Telemetry System The control and alarm system will be maintained and updated as necessary to optimize all policy goals. Controls must be capable of optimizing the operation of the water system’s components in response to reservoir levels, system pressures, abnormal system conditions, electrical power rate structure, and water costs 56. 5.3.7.8 Construction Standards All new water system infrastructure shall be designed and constructed to comply with DOH criteria, AWWA standards, the City’s latest design criteria, and good engineering practice. 5.3.7.9 Standard Useful Life for Design • Distribution system pipes – 80 years. • Electrical equipment – 10 to 20 years (varies by type). • Mechanical equipment – 10 to 20 years (varies by type). • Structures – building shell – 50 years. • Structures – water storage – 50 years. • SCADA hardware and software – 10 years (technical obsolescence). • Human Machine Interface (HMI) hardware and software - 5 years (physical limit / technical obsolescence). 5.3.7.10 Facilities Maintenance All City water facilities and related equipment will be maintained so that they perform at the level of service necessary to meet all operational policies and service delivery goals. Equipment breakdown are given highest maintenance priority and repairs should be made as soon as possible to restore the established level of service and for continuity of operation. Equipment should be scheduled to be replaced or upgraded before they become obsolete or when spare parts are no longer available. Worn parts should be repaired, replaced, or rebuilt before they represent a high failure probability. A preventive maintenance schedule shall be 55 Source: WAC 246-290-200, DOH Water System Design Manual, Water System Plan. 56 Source: DOH, Water System Plan.

The City ensures that Water Maintenance staff obtained the required State water works certifications by WAC 246-292, such as for Water Distribution Managers and/or Water Treatment Operators, to maintain and operate the City’s water system. Maintenance shall be performed by the water maintenance staff and supervised by the Field Superintendent. Written records and reports will be maintained on each facility and item of equipment showing operation and maintenance history 57. 5.3.7.11 Joint Use Facilities The City will participate in regional projects to the extent that the level of service is not compromised or the cost of service inequitable. All joint-use facilities must comply with City policy and design standards. Joint-use facilities which supply a portion of the City that cannot be supplied from other sources in the event the joint-use facility is out of service will be maintained by the City. Joint-use facilities will be pursued only in those areas that improve reliability or operating costs 58. 5.3.8 Organizational Policies 5.3.8.1 Structure The Water Utility will be structured to provide the best level of service at the least cost. Utility staff level is established by the Council based on financial resources and desired level of service to be provided by the City. The Water Utility shall be part of the following divisions: • Public Works /Utility Systems/ Water Utility Engineering for the planning, management, design, and construction of the City water system and the development and updates of policies and design standards. • Public Works Maintenance Services/ Water Maintenance for the operation and maintenance of the City water system. • Community and Economic Development/Plan Review and Permitting for the review, permitting, and inspection of developers’ extensions of City water system. • Finance & Information Technology/Fiscal Services for financial and utility billing services, cost accounting, and fund activity reporting. 5.3.8.2 Project Review Procedures The City submits projects for new sources, water treatment facilities, booster pump stations, reservoirs, and the recoating of the interior of existing reservoirs to DOH for review and approval as per WAC 246-290-110, -120 and -130.

City staff reviews and approves projects for the installation, maintenance, and repair of control, telemetry, and SCADA systems of the drinking water system. The Water Utility Engineering Manager reviews project plans for compliance with DOH and City design and construction standards including compatibility with the objectives of the Plan. The Water Utility Engineering Manager consults with Renton RFA staff and the Water Maintenance Managers as part of the review. The review addresses separation from sanitary sewers, other non-potable conveyance systems, and sources of contamination; service pressures; fire flow volumes, velocities, and pressures; cross connection control; thrust block and anchoring requirements; corrosion control and protection; air and vacuum control; meter and service line sizes; PRV requirements; operations and maintenance considerations (blocking valves, blow-offs, etc.); construction considerations (cleaning with polypigging, pressure testing, chlorination, flushing, and bacterial testing); etc. Some reviews include hydraulic modeling by the Water Utility staff. The City requires that the plans include applicable standard details and that the plan notes repeat key provisions of the City specifications for the construction and testing of water distribution system mains and appurtenances. Plans must be signed and stamped by a Washington State licensed professional engineer. The Water Utility Engineering Manager indicates his approval of the plans by signing and dating the construction drawing originals within a City approval block 59. 5.3.8.3 Requirements for Outside Parties The policies pertaining to water distribution system facilities and financing are listed above and are applicable to both City CIP projects and private developer projects. Normally during the planning phase of a Developer-project, a pre-application conference is held with the Developer’s engineer. Members of the Water Utility engineering staff, Renton RFA staff, and Development Services staff participate in the meeting. Based upon the preliminary information about the proposed project the City staff reviews with the Developer’s engineer anticipated requirements for the project: main sizes and main extents, fire flow, looping, pressure control and pressure issues, construction practices, etc. The City’s design standards and policies regarding water main extensions by developers and related requirements are described in Appendix K of this Plan 60. Fire flow requirements are determined by Renton RFA. The City Water Utility first determines sufficient water rights are available. Then, the City Water Utility will determine the available fire flow using its computer simulated hydraulic model of the City water distribution system. The minimum allowable system pressure during fire flow analysis is 20 psi at the fire location and 30 psi throughout the rest of the distribution system. New developments or redevelopment of existing sites are required to meet the minimum City fire flow requirements. The Developer is responsible for the design and installation of all necessary water main improvements to provide the required fire flow including off-site and on-site water mains. The change of use of existing buildings or areas may also require the installation of the water main improvements. 59 Source: DOH, Water System Plan. 60 Source: DOH, Water System Plan. CHAPTER 06 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 6-1 Chapter 6 WATER SUPPLY, WATER RIGHTS, AND WATER QUALITY To meet water demands, the City of Renton (City) has developed its own independent water supply sources as well as designed interties with adjacent purveyors to purchase wholesale water. This chapter describes the City’s sources of supply, including the condition and capacity of its sources; the water rights associated with its sources; and the water quality requirements for its sources. This chapter also provides a summary of the City’s Wellhead Protection Program (WHPP). The City will maintain its capability to supply a growing population and control water rates by: 1. Placing additional emphasis on water conservation via customer education, incentive programs, and rates that encourage conservation. 2. Protecting the water quality of existing sources from adverse development impacts in the capture zones. 3. Continuing “beneficial use” of its well supply and protecting the legal integrity of the existing water rights. 4. Negotiating with adjacent utilities for emergency supply. 5. Participating in regional water supply organizations. Water quality policies and programs to protect existing groundwater supply sources are among the City’s highest priorities. To ensure public health protection, the City has established a monitoring program that covers operational parameters, regulatory requirements, and aquifer management. 6.1 Water Supply Sources The City’s normal supply is derived from four water sources: the Downtown Wellfield, Springbrook Springs, the Maplewood Wellfield, and Seattle Public Utilities (SPU) supply interties. The City also has an emergency backup well (Well EW-3R), a backup well (Well PW-5A), and emergency supply interties with adjacent purveyors. These supply sources are described in the sections below and are shown on the water system map included in Appendix F, System Maps. The SPU source of supply is described under Section 6.5 - Interties. 6.1.1 Cedar Valley Aquifer The primary source of the City’s municipal water supply is the Downtown Wellfield, which draws water from the deltaic portion of the Cedar Valley Aquifer (also referred to as the deltaic aquifer). The Cedar Valley Aquifer has been designated a Sole Source Aquifer (SSA) by the United States Environmental Protection Agency (USEPA) since 1988. The aquifer boundaries correspond to the aerial extent of the post-Vashon alluvium of the lower Cedar River Valley. In the vicinity of the wellfield constructed in downtown Renton, the aquifer consists of coarse-grained sediments deposited at the mouth of the prehistoric Cedar River during the last CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 06 6-2 | MAY 2021 | FINAL glacial period. The average water table is approximately 23 feet below ground surface (bgs) and the average aquifer thickness is roughly 70 feet in the vicinity of the wellfield. This shallow aquifer is highly susceptible to contamination since there is no confining layer between the land surface and the water table to retard the downward migration of hazardous chemical spills or other releases of contaminants. 6.1.1.1 Aquifer Characteristics Soils overlying the aquifer are silt, sand, and gravel while the aquifer itself is comprised of coarser, very permeable sandy gravel. Aquifer transmissivity is estimated to range from about 1 to 2.3 million gallons per day per foot (mgd/ft). The transmissivity and specific yield of the City’s wells located in that Cedar Valley Aquifer are summarized in Table 6.1. Table 6.1 Wells Transmissivity and Specific Yield Summary Well Name Transmissivity (mgd/ft) Specific Yield (cf/cf) RW-1, RW-2, RW-3 1.00 0.025 PW-8 1.30 0.030 PW-9 2.30 0.020 Notes: (1) Source: Analysis Report for the City of Renton Cedar River Valley Aquifer Test, RH2 Engineering, 1987. Abbreviation: cf - cubic feet. The hydraulic conductivity is on the order of 2,500 feet per day (ft/day) assuming an average transmissivity for all the Cedar Valley Aquifer wells of 1.3 mgd/ft. Recharge is local, both from direct precipitation and subflow. The Washington State Department of Health (DOH) contamination susceptibility rating of wells located in the Cedar Valley Aquifer is moderate to high. 6.1.1.2 Downtown Wells The City operates six production wells (RW 1, RW 2, RW 3, PW 8, PW 9, and EW-3R) in the Cedar Valley Aquifer. Wells RW-1, RW-2, and RW-3 each have a pumping capacity of 2,200 gallons per minute (gpm) and are screened at depths ranging from 50 to 105 feet bgs. Well EW-3R may be used in case of an emergency. Its capacity is 1,600 gpm and it is screened from 40 to 70 feet bgs. Wells PW-8 and PW-9 have pumping capacities of 3,500 and 1,200 gpm, respectively. The wells are screened at depths ranging from 50 to 105 feet bgs. Further detail is available in Chapter 2 – Existing System. 6.1.2 Springbrook Springs Approximately 15 percent of City’s current water supply comes from Springbrook Springs, located at the southern city limits. A water-bearing sand and gravel layer enclosed in a thick sequence of glacial till intercepts the surface of the hillside at Springbrook Springs. Two infiltration galleries collect and channel water into the transmission pipeline. Flow measured at the Springbrook treatment building varies over the year with the highest flow rates occurring during the summer months. The City is able to maintain a maximum flow of 1,050 gpm into the distribution system via a throttling valve. Section 6.4 of this chapter describes recommendations and potential changes to the operation of the throttling valve to allow higher flow from Springbrook Springs. CHAPTER 06 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 6-3 The capture area has been estimated by combining the surface area draining to Springbrook Springs with the estimated groundwater recharge area. The latter is based on well driller reports for wells in the vicinity of the spring. The DOH contamination susceptibility rating of Springbrook Springs is moderate to high. 6.1.3 Maplewood Production Aquifer The Maplewood Production Aquifer is located east of the downtown area under the Maplewood Golf Course. It serves as a redundant source of supply for the vulnerable Cedar Valley Aquifer. 6.1.3.1 Aquifer Characteristics This aquifer is believed to extend northward into hydrostratigraphically correlated zones beneath the North Uplands. It ranges from 70 to 120 feet thick and is encountered from approximately 135 to 345 feet below the golf course. The Maplewood Production Aquifer is confined with evidence of some leakage. Gradients are predominantly upward. Estimated transmissivities range from 49,000 to 76,000 gallons per day per foot (gpd/ft) with corresponding hydraulic conductivity ranging from 94 to 128 ft/day. Recharge is believed to occur predominantly from the North Uplands while discharge occurs in the Cedar Valley via upward flow to the alluvial aquifer east of the bedrock narrows. Other recharge and discharge points may exist. The DOH contamination susceptibility rating of the Maplewood Aquifer is low. 6.1.3.2 Maplewood Wells The City has three Maplewood Wells (PW-11, PW-12, and PW-17), which have pumping capacities of 2,500 gpm, 1,600 gpm, and 1,500 gpm, respectively. These wells are screened at depths ranging from 284 to 344 feet bgs. The City has a permit for a water right at this location for a new Well 10. The City has no current plan to develop this well. 6.1.4 Well PW-5A Well PW-5A is located near the northern city limits east of Lake Washington. This backup well has a pumping capacity of 1,500 gpm and is completed in a sand and gravel aquifer zone approximately 280 to 390 feet bgs (about -42 to -152 feet mean sea level). The aquifer zone is overlain by stratified glacial deposits of fine to coarse sand and gravel layered with silt and clay. The capture zone for Well PW-5A is not known, but there are some indications that the well may be withdrawing from the Maplewood Aquifer. The DOH contamination susceptibility rating of Well PW-5A is low. 6.2 Condition of Supply Sources The City’s wells are generally in very good condition. The City has capital improvement and maintenance programs to upgrade and maintain its sources in good condition and to comply with water quality criteria. Chapter 8 – Operation and Maintenance summarizes City maintenance activities. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 06 6-4 | MAY 2021 | FINAL 6.3 Supply Management The City manages each water supply source within the limitations of the instantaneous water right quantity (Qi) and annual water right quantity (Qa) established by the Washington State Department of Ecology (DOE). In general, the City’s sources are equipped with capacity to deliver the full certificated City water rights (or in the case of the Maplewood Wells – the permitted Qi flows) to the distribution system. Without obtaining authorization from DOE to use the Maplewood Wells to provide additional instantaneous flow as originally intended, not all of this installed capacity can be utilized. For the current planning period, the City plans to use the Maplewood Wells as alternate sources only and to revisit the terms of these water right authorizations during the next planning period. The combined withdrawals from the Cedar Valley Aquifer sources and the Maplewood Aquifer sources will not exceed the total certificated Qi of 11,400 gpm for the Downtown Wells and total certificated Qa of 14,809 acre-feet per year (ac-ft/yr) for all sources. Springbrook Springs will be used at its full available supply during the planning period. At present, Well PW-5A is only used for backup supply because of the water quality issues mentioned in Chapter 2 of this Plan. During the current planning period the City anticipates that on infrequent occasions the demand will exceed the Qi water rights of the Cedar Valley sources and Springbrook Springs. During these periods the City plans to meet the demand by purchasing wholesale water from SPU. 6.4 Water Rights Analysis 6.4.1 General Conditions The State Water Code, as outlined in Title 90 of the Revised Codes of Washington (RCW), states that all surface and ground waters of the state are the property of the public. It is, therefore, the policy of the state to promote the use of the public waters in a fashion that provides the maximum benefit arising from both diversionary uses of the state's public water and the retention of waters within the streams and lakes in sufficient quantity and quality to protect in-stream and natural values and rights. (90.03.005 RCW): The state takes responsibility for determining who, among the various competing basin stakeholders, is allowed to use, divert, or consume the water. When an application to obtain water rights is submitted to the DOE, the date of receipt of this application establishes the priority of the water right. Prior to the development of a source of supply, a permit is issued by DOE to construct, develop, and test the supply source. A water right may then be issued following a thorough review process, a determination of the amount of supply that is put to beneficial use, and the impacts on the various other basin stakeholders. This water right establishes the priority use of the water and becomes an appurtenance to the property. The City has developed independent water sources in order to maintain greater control over the management and costs of its water supply. Through the development of independent sources of supply, the City strives to protect public health, ensure adequate water supply to meet the requirements of its customers, and support the economic prosperity of the City. CHAPTER 06 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 6-5 Consistent with DOE's procedures for issuing water rights, all of the City’s water rights specify a Qi and a maximum Qa. Copies of the City's water rights certificates and permits are in Appendix M. 6.4.2 Existing Water Rights The City has 13 water right certificates and 4 permits. A summary of the City’s existing water rights for municipal supply is presented in Table 6.2. The total instantaneous flow rate from the certificated rights is 15,152 gpm. Certificated additive (primary) annual water rights are 14,809.5 ac-ft/yr. Certificated non-additive (previously termed supplemental) annual water rights are 7,539 ac-ft/yr. Well 4 is currently inactive, as is Well PW-5A which is only used as backup due to water quality issues. These sources authorize total primary water right allocations in the amount of 1,670 gpm and 2,593.5 ac-ft/yr, which is being exercised through the use of supplemental sources. The City’s water rights authorize total primary allocations in the amount of 15,152 gpm and 14,809.5 ac-ft/yr. The water right for Well EW-3R (GWC 5836-A) was transferred to the new wells RW-3, RW-1, and RW-2. However, in accordance with the water right certificate, Well EW-3R continues to be maintained should it be needed to intercept contaminants that could affect the other wells. Well EW-3R can also be used as an emergency supply after notifying DOE, in the event that the City’s other sources fail. In 2011, the City requested an additional development extension of the Maplewood Wellfield and was granted until September 30, 2021 to finalize the rights and file the Proof of Appropriation forms. The City continues to operate the sources consistent with the past arrangement with DOE to not exceed the total Qi and Qa authorized by the Cedar Valley sources; however, the final disposition of these permits has not been resolved. 6.4.3 Forecasted Water Rights The City does not anticipate applying for any new water rights or changes to its existing water rights. In 1997, the City applied for a change of place for several of its water rights, but since then it has withdrawn those applications. The City’s forecasted water rights are the same as its existing water rights. Springbrook Springs have both a surface water certificate and groundwater certificate, which, if added together would put the withdrawal amount to 2,082 gpm. The City currently has a throttling valve and is maintaining the flow at the Qi value of 1,050 gpm (groundwater certificate value). The City has the ability to increase the withdrawal amount with the infrastructure currently in place, and will, on an as needed basis, withdraw up to the combined value of 2,082 gpm. The City plans to use the Maplewood wells as alternate sources only and to revisit the terms of these water right authorizations perfecting water right certificates during the next planning period.

The City and SPU have a wholesale supply contract (renewed in 2011), which provides an additional supply source for the City through 2062. The City has nine metered interties with the SPU transmission mains (including the two Boeing Plant meters), which are available to serve wholesale water to the City. The City’s interties are summarized in Table 6.3 and described in detail in Chapter 2 as part of the supply sources. Most interties receive summer peaking supply, with the greatest supply from pressure-reducing valve (PRV) 24 / SPU Bow Lake Pipeline Sta. #196. The City plans to meet its water demand needs that cannot be met by way of its own sources of supply and/or via storage by purchasing water from SPU.

CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 06 6-10 | MAY 2021 | FINAL 6.6 Water Right Self-Assessment A water right self-assessment was made based on all water right permits, claims, and certificates. The self-assessment compares the current and 20-year projected water demand to determine the adequacy of the City’s water rights. The self-assessment also considers Table 6.4. The City currently has sufficient water rights. If the City does not pursue additional treatment for Well PW-5A, does not redevelop Well 4, and does not expand capacity of the Springbrook Springs water right, the available annual water right will be 10,566 ac-ft (equivalent to 9.43-mgd average day demand [ADD]), and the City could face a source capacity issue that would result in exceeding this usable annual water. The City plans to address the forecast difference between Qa water rights and annual demand by purchasing water from SPU. To address the forecast difference between Qi water rights and demand, the City plans to construct additional storage and purchase water from SPU. Additionally, the City will further evaluate the timing of capital improvements to address the water quality problems of Well PW-5A. The details of the supply and pumping analysis are presented in Section 6.13. 6.7 Water Quality Plan and Treatment The City is defined as a Group A Community Public Water System. The City must comply with the drinking water standards of the federal Safe Drinking Water Act (SDWA) and DOH standards under Washington Administrative Code (WAC) 246-290. The City’s water quality is in compliance with all state and federal water quality and reporting requirements. The City maintains water quality within its system through the following approaches: 1. Routine system flushing within its distribution system in order to maintain satisfactory water quality. 2. A main replacement program to eliminate dead end mains and replace aging cast iron, asbestos cement, and steel pipes. 3. In-line chlorine and fluoride analyzers at all sources for continuous monitoring. 4. Installation of pH meters at all sources in order to better manage pH and as a result reduce corrosion within the distribution system. 5. Cross-connection prevention. It is recommended that the City take the following actions as part of its water quality planning programs: • The City should continue to track proposed new water quality rules and regulations being considered by the USEPA and DOH in order to plan for any impacts on its water system. • The City should continue to implement its corrosion control treatment improvements as necessary to reduce levels of corrosion within the distribution system and private plumbing. CHAPTER 06 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 6-11 6.7.1 Raw Water Quality A review of the City's raw water quality testing records indicates that overall source water quality is excellent with only minor aesthetic problems caused by ammonia, iron, manganese, and hydrogen sulfide at Maplewood and corrosivity concerns at Springbrook Springs and Downtown. Even though the aesthetic components do not affect public health, the City provides treatment to improve aesthetic quality in terms of odor and discoloration. Corrosion treatment reduces health risks associated with potential leaching of lead and copper from piping, but also improves aesthetics as well. 6.7.2 Treatment The City’s water treatment is described in detail in Chapter 2 as part of the supply sources. Table 6.4 summarizes the current source treatment goals and effectiveness. The City upgraded the treatment systems at both Springbrook Springs in 2013 and the Downtown Wells in 2010 to modernize the disinfection systems and add sodium hydroxide for pH adjustment to reduce the corrosivity of the water. Water treatment improvements at the Maplewood Wells were completed in 2006 to remove hydrogen sulfide, manganese, and ammonia. The Maplewood Treatment Plant is currently able to deliver up to 3,000 gpm to the distribution system, with provisions to allow additional filters that would increase the capacity to 5,500 gpm. For regular use of Well PW-5A, treatment for ammonia, iron, manganese, and hydrogen sulfide is required. There is no plan to provide additional treatment for Well PW-5A within the next 20 years. Adding treatment to Well PW-5A will be examined during the next planning period. 6.7.3 Water Quality Monitoring The City has implemented a comprehensive and proactive water quality monitoring program. It includes monitoring for operations, regulatory monitoring to meet the requirements of the federal SDWA and monitoring to manage the City's aquifers. Operational monitoring is used to verify the City’s water facilities are functioning effectively to deliver high quality drinking water, and includes measuring chlorine and fluoride concentrations, pumping rates for each production well, and pH measurements as part of the corrosion control program. Regulatory monitoring includes analytical testing for microbial pathogens, organic and inorganic chemicals, disinfection byproducts, and radionuclides. The sampling is performed at locations and at frequencies required by state and federal regulations. Aquifer monitoring is used to identify contamination and to track water levels in the aquifers.

CHAPTER 06 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 6-15 Water quality sampling is the responsibility of the Water Maintenance Services Division and is carried out on a daily basis by a team of Water Treatment Operators. In addition to ensuring that water treatment and maintenance are performed effectively, the Water Maintenance Services Division is responsible for ensuring that monitoring is carried out and for managing water quality data and records both for routine and special monitoring programs. A detailed description of the water quality sampling methods, the sampling locations, sampling frequency, and record keeping procedures are listed in the Drinking Water Quality Monitoring Program included as Appendix N. The estimated costs for the City's water quality monitoring are included in Chapter 8 - Operations and Maintenance. 6.8 State and Federal Regulatory Requirements This section presents the water quality standards of the DOH and USEPA through the SDWA. The SDWA, which was enacted in 1974 (and amended in 1986 and 1996), is the main federal law that establishes standards for drinking water quality for public water systems. The DOH has adopted the federal drinking water regulations under WAC 246-290 and has accepted primary responsibility (or “primacy”) for enforcement of water quality monitoring and reporting. All existing and anticipated drinking water regulations that apply to the City are summarized in the following subsections and shown in Table 6.5. 6.8.1 Revised Total Coliform Rule The Revised Total Coliform Rule (RTCR), which replaced the 1989 Total Coliform Rule, requires monitoring to demonstrate that a water system is minimizing the risk of bacterial growth. Drinking water samples must be collected for bacteriological analysis from representative points in the distribution system at regular time intervals. The number of water samples is dependent upon the population being served by the system. Currently, testing for bacteria (total coliforms) is conducted weekly, with a total of 100 samples required each month. Over the past 6 years, the City has collected approximately 7,000 coliform samples (post-treatment) and only 2 have come back positive for total coliforms. Follow-up actions were taken following the detections, but repeat samples showed no indication of contamination. The City is required to have a Coliform Monitoring Plan that identifies coliform monitoring locations and sampling procedures. The City’s Coliform Monitoring Plan is included as Appendix A of the Drinking Water Quality Monitoring Plan, which can be found in Appendix N. 6.8.2 Stage 1 and 2 Disinfectants/Disinfection Byproducts Rules Because the City uses chlorine for disinfection, it needs to meet the requirements of the Stage 1 and Stage 2 Disinfectants/Disinfection Byproducts Rules (D/DBPR). In general, the City’s high-quality source water and applied treatment result in low concentrations of disinfection byproducts, which are produced from the reactions between chlorine and natural organic matter. Based on the low levels of trihalomethanes and haloacetic acids, which are the two most common disinfection byproducts, the City is approved for reduced monitoring. D/DBPR compliance monitoring is described in detail in the City’s Stage 2 Disinfectants and Disinfection Byproducts Monitoring Plan, which is included as Appendix B of the Drinking Water Quality Monitoring Plan.

CHAPTER 06 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 6-17 Regulation Effective / Compliance Dates Regulation Summary and City Status PFAS DOH began rulemaking for PFAS in drinking water in late 2017 The City tested all of its sources for 6 PFAS chemicals as part of UCMR3 sampling in 2014 and 2015. All samples were non-detect. Strontium USEPA is considering issuing a regulatory standard based on UCMR3 results The City is monitoring the development of a national primary drinking water regulation for strontium. LCR Long-Term Revisions USEPA is considering additional revisions to the LCR The City is monitoring the development of the rule revisions. UCMR5 Anticipating final rule in 2021, with a compliance period of 2023 to 2025. Note: Abbreviations: UCMR3 / UCMR4 / UCMR5 - Unregulated Contaminant Monitoring Rules 3, 4, and 5; PFAS - per- and polyfluoroalkyl substances. 6.8.3 Groundwater Rule The Groundwater Rule builds on the Total Coliform Rule by addressing the health risks of microbial pathogens (bacterial and viral) in community public water systems that use groundwater sources. The City has 4-log virus treatment (99.99 percent inactivation) at each source of supply and conducts routine compliance monitoring. The City also conducts periodic sanitary surveys to address system deficiencies at risk of microbial contamination. 6.8.4 Arsenic Rule The Arsenic Rule was adopted by the DOH as a revision to the arsenic maximum contaminant level (MCL) under WAC 249-290-310. The City samples for arsenic during the inorganic chemical analysis and all samples were non-detect for arsenic during the last monitoring period. 6.8.5 Radionuclides Rule The City conducts periodic monitoring (once every 6 years) for radiological contaminants (radionuclides) at each source after treatment. During the last monitoring period (June 2016), all samples were non-detect for Gross Alpha particles and Radium 228. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 06 6-18 | MAY 2021 | FINAL 6.8.6 Inorganic Chemical Analysis Inorganic contaminants are metals, salts, and other non-carbon compounds that can be naturally occurring in the environment or are present as a result of human activities such as urban stormwater runoff or industrial wastewater discharges. Physical properties of inorganic chemicals that affect water quality are also included in the analysis such as hardness, turbidity, color, conductivity, and total dissolved solids. The City is required by DOH to take samples for inorganic chemical analysis at each source after treatment. The complete inorganic chemical and physical analysis includes the primary and secondary chemical and physical drinking water contaminants specified in WAC 246-290. Based on historically low levels, the City has been approved by DOH for reduced monitoring (once every nine years) with the exception of nitrate, which is monitored annually. The City also has a permanent waiver for asbestos monitoring from DOH. During the last monitoring period, no samples exceeded the MCLs for inorganic chemicals. Fluoridation of the City’s water supply began in 1985 after Renton citizens voted for fluoride treatment. In 2016, the City adjusted its fluoride target level to 0.7 mg/L with an operating tolerance of 0.5 to 0.9 mg/L as recommended by both DOH and Centers for Disease Control and Prevention (CDC). During the last 6 years, no samples have exceeded the MCL for fluoride. 6.8.7 Organic Chemical Analysis Volatile organic chemicals (VOCs) are carbon-containing substances that easily become vapors or gases under typical room temperature. Some VOCs are hydrocarbons that are associated with petroleum fuels and solvents. VOCs are divided into regulated and unregulated VOCs. There are currently 21 regulated VOCs that have been determined to pose a significant risk to human health. This group does not include organic pesticides, herbicides, or insecticides, which are regulated separately as synthetic organic chemicals (SOCs). There are currently 33 regulated SOCs. The City is required by DOH to take samples for organic chemical analyses at each source after treatment. Based on historically low levels, the City has been approved by DOH for reduced monitoring (once every 6 years for VOCs and once every 9 years for herbicides). The City has also been granted waivers for pesticides and soil fumigants. State-wide waivers have been issued for insecticides, dioxin, diquat, endothall, glyphosate, polychlorinated biphenyls (PCBs), ethylene dibromide (EDB), and dibromochloropropane (DBCP). Recent chemical analyses of the City's supply sources show no contamination from VOCs or SOCs. The City must test for trihalomethanes at all wells once a year since they are chlorinated. During the last monitoring period, low levels of trihalomethanes were detected in the samples, but were significantly below the MCL for total trihalomethanes. 6.8.8 Lead and Copper Rule Action levels were established for lead and copper under the 1991 LCR. The goal of the LCR is to protect public health by minimizing lead and copper levels at consumers’ taps, primarily by reducing water corrosivity within the distribution system. The 2007 Short-Term Revisions to the LCR enhanced monitoring, treatment, lead service line replacement, public education, and customer awareness. CHAPTER 06 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 6-19 The City’s source water contains no significant amounts of lead and copper. However, potential health risks come from the leaching of lead and copper from the distribution system components and private plumbing. The City reduces the risk of leaching by continuously treating its source water to raise the pH of the water. Additional details on these facilities are provided in the Corrosion Control section. LCR sampling was most recently conducted in 2016. There were 41 samples tested for lead and copper from residential water taps. All of the samples tested had levels far below the action levels for both lead and copper. A detailed description of the 2016 LCR sampling is provided in Appendix N, Drinking Water Quality Monitoring Program. Although the LCR has resulted in substantial reductions in lead in drinking water, the EPA is proposing additional revisions to improve the rule and strengthen public health protections. Proposed revisions to the LCR include requirements for accelerated lead service line replacement programs, improved optimal corrosion control treatment requirements, incorporating a lower trigger level for lead, point of use filters, improving sampling procedures, increased transparency and information sharing, and public education. 6.8.9 Unregulated Contaminant Monitoring Rule The SDWA establishes periodic monitoring of contaminants that are suspected to be in drinking water, but not yet subject to drinking water regulations. This is the fourth cycle of monitoring for unregulated contaminants (UCMR4). Because the City uses groundwater supply sources, UCMR4 monitoring consists of 20 unregulated chemical contaminants: two metals, eight pesticides plus one pesticide manufacturing byproduct, three brominated haloacetic acid disinfection byproducts groups, three alcohols, and three semivolatile organic chemicals. The City submitted a Groundwater Representative Monitoring Plan proposing three representative sampling locations (Springbrook Springs, Downtown Wellfield, and Maplewood Wellfield). The monitoring plan was approved by USEPA in January 2018. The City performed UCMR4 sampling in October 2018 and April 2019. Unregulated contaminants that were detected during these UCMR4 sampling events will be reported in the 2019 and 2020 Water Quality Reports. While these contaminants do not have established drinking water standards, the data collected during UCRM4 provides a basis for potential future regulatory actions to protect public health. 6.8.10 Consumer Confidence Report Rule The Consumer Confidence Report (CCR) is an annual water quality report that a community public water system is required to prepare for its customers. Each year, the report documents regulated contaminants detected during the water system’s most recent monitoring period (within five years), and the concentrations of these detected contaminants compared to regulatory standards. The report must also include the health effects related to violations of the maximum contaminant levels. The information in the report is provided to help consumers make informed decisions about their drinking water. The City’s Water Quality Monitoring Reports are electronically available at: https://rentonwa.gov/city_hall/public_works/utility_systems/water_quality_report CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 06 6-20 | MAY 2021 | FINAL 6.8.11 Public Notification Rule The Public Notification Rule requires public water systems to notify their consumers of drinking water violations or situations that may pose a risk to public health. Public notification is intended to ensure that consumers will know if there is a problem with their drinking water. There are three categories of public notification: • Tier 1 (Immediate Notice) – Notification within 24 hours. • Tier 2 (Notice as Soon as Practical) – Notification as soon as possible, but within 30 days. • Tier 3 (Annual Notice) – Up to a year to provide notification. The City has not had a drinking water violation in the last 6 years requiring public notice. The City has a detailed public notification procedure summarized in the Coliform Monitoring Plan included in Appendix N. 6.8.12 Future Regulations The City is monitoring the developments surrounding the following potential rules and rule changes: • Revisions to the LCR are being monitored and changes to the City’s LCR activities will be made if necessary. • Proposed Strontium Monitoring – not anticipated to effect the City. • Proposed PFAS Monitoring – not anticipated to effect the City. • Proposed Perchlorate Monitoring – not anticipated to effect the City. 6.9 Corrosion Control Program 6.9.1 Corrosion Protection: Source of Supply In the past, there were relatively high copper levels, and occasionally high lead levels, at home taps because of the relatively low pH of Cedar Valley Aquifer and Springbrook Springs water supplies. In 2017, the raw water pH ranged from 6.6 to 6.9 for the Downtown Wells and about 6.9 to 7.1 for Springbrook Springs. Water with pH less than 7.2 is aggressive in leaching copper and lead from water mains and private plumbing. As a result of the low pH levels, the City has added corrosion control treatment to its Downtown Wells and Springbrook Springs. Sodium hydroxide is added to these sources to raise the pH to between 7.3 and 8.1. The pH of the raw water from the Maplewood Wells is approximately 8.1 and that of the treated water is about the same. Well PW-5A water has a pH of approximately 8. The Corrosion Control Recommendation Report (March 1995) found that no additional corrosion control treatment processes are required for these sources. 6.9.2 Corrosion Protection: Distribution Mains The City uses Aqua Mag® blended phosphates in areas of the distribution system that contain a high number of unlined cast iron water mains. It acts to control the corrosion of the interior surfaces of water mains. The City uses sampling stations to monitor pH levels in the distribution system. In 2017, the pH averaged 7.7 at these stations. CHAPTER 06 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 6-21 Since about 1976 the City has required that all water mains installed in the City be cement-lined ductile iron pipe. Additionally, since 1980, the City has required that water mains installed in high resistivity soils be wrapped in polyethylene. Beginning in 1994, the City specifications have required that all water mains be wrapped in polyethylene. These requirements were established to reduce the internal and external corrosion of water mains. In a few of the locations where the City’s water mains are within the influence area of other utility lines that are protected with impressed current cathodic protection systems, the City’s water mains are electrically bonded and/or protected with sacrificial anodes. Test stations are installed. Testing is random and infrequent at this time. 6.9.3 Corrosion Protection: Steel Reservoirs and CT Pipeline Three of the City’s seven steel reservoirs are protected with impressed current cathodic protection systems (Mt Olivet, Highlands 565, and Rolling Hills 590). The West Hill reservoir has an active impressed current cathodic protection system installed. The seven reservoirs are inspected by a corrosion control consultant approximately every five years. The inspections consist of examining the protective coatings as well as the cathodic protection systems. The interior and exterior protective coatings are repaired and/or replaced as recommended by the consultant. Impressed current systems are checked annually. Adjustments and maintenance actions are made to the impressed current systems based upon the consultant’s recommendations. The CT Pipeline used to provide primary disinfection for wells RW-1, RW-2, and RW-3 has an impressed current cathodic protection system installed but there has not been a need to energize it. 6.10 Wellhead Protection Program The 1986 amendments to the federal SDWA mandated that every state develop a WHPP to protect ground waters that serve as drinking water sources for public water supplies. In 1994 DOH adopted WAC 246-290, which directed Group A public water systems using wells or springs to implement wellhead protection measures. The City prepared its WHPP, which was approved by DOH in December 1999. Updates to the City’s WHPP were completed under this Plan and the changes to the WHPP are included as Appendix J. DOH stipulates that local WHPPs shall, at a minimum, include the following elements: • A completed susceptibility assessment. • A delineated wellhead protection area for each well, wellfield, or spring. • An inventory of contamination sources located in the wellhead protection area that have the potential to contaminate wells or springs. • Documentation that delineation and inventory findings are distributed to property owners and regulatory agencies. • Contingency plans for providing alternate sources of drinking water in the event that contamination does occur. • Coordination with local emergency responders for appropriate spill response measures. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 06 6-22 | MAY 2021 | FINAL Compliance with WHPP requirements is part of a broader City effort referred to as the “Aquifer Protection Program.” The Aquifer Protection Program was established in 1988 when the Renton City Council designated Aquifer Protection Areas (APAs) with the intent of safeguarding the City’s supply sources. The APAs that were initially delineated in 1988 were redefined during this WHPP update to be consistent with the capture zones, which were delineated using the City’s Groundwater Model. As part of its Aquifer Protection Program, the City has enacted aquifer protection regulations within the APAs to protect the aquifers used as potable water supply sources from contamination by hazardous materials. The regulations include restrictions on hazardous material quantities, storage, and handling; land use restrictions; facility operating standards; construction activity standards; fill quality standards; and other measures intended to prevent contamination. Other components of the Aquifer Protection Program include public education, aquifer water quality and level monitoring, coordination with emergency responders, and coordination with surrounding land use authorities on groundwater protection issues. 6.11 System Reliability The City continues to meet its responsibility to its customers and as a water purveyor by addressing the reliability of the water system through the quality and condition of its facilities described earlier in this chapter; through system redundancy; and through the development and implementation of its Vulnerability Assessment and its Water Shortage Response Plan. 6.11.1 Reliability Efforts The City continues to provide reliable water service to its existing customers and plan for long-term reliability of its system for its sources and its distribution network. The City’s primary supply is from its Downtown Wells and Springbrook Springs. Emergency Well EW-3R can be used in the event that the normal supply wells are unavailable. In addition to the Cedar Valley Aquifer, the City can supply its system from two different sources within its service area, the Maplewood Aquifer (not additive) and Well PW-5A. In 2007 the City added emergency electrical generation facilities to supply power to Wells RW-1, RW-2, and RW-3 and to Mt. Olivet and North Talbot BPSs. See Chapter 2 - Existing System and Chapter 9 - Capital Improvements Program for further discussion of existing and planned emergency backup power. In addition to its own sources of supply, the City also has 10 existing interties with four neighboring water utilities: seven from SPU, one from Tukwila, one from Kent, and one from Skyway (plus two 10-inch supply lines to the Renton Boeing Plant from SPU). The City is also actively participating in and is studying other options to increase supply reliability. These options include the City’s ongoing Conservation Plan, a future aquifer recharge study, and the continuing examination of opportunities for the use of reclaimed water. 6.11.2 Water Shortage Response Planning The City developed a Water Shortage Response Plan in 1989 to meet its responsibility for planning for emergencies or other short- or long-term shortages that may occur. The updated Water Shortage Response Plan is included in Appendix O. CHAPTER 06 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 6-23 6.12 System Wide Water Supply Planning The City has been decisive and progressive in its water supply planning. The City has pursued its independent acquisition of water sources in order to maintain control over this utility, which is vital to the public health and economic well-being of its customers. An important consideration has also been concerning the cost of water supply and the desire to keep water rates low and competitive with neighboring systems and with the region as a whole. The City’s supplies were evaluated to identify if they provide adequate capacity is available to serve future demands. Reliable and redundant supplies were evaluated on maximum day demand (MDD) with the largest pump or source out of service. For the purpose of this study, the term “reliable” refers to a non-emergency source of supply that has backup power. The City has more than sufficient supplies to meet the system wide MDD through 2039, as shown in Table 6.6. The City-owned supplies are sufficient to meet the system-wide MDD through 2029, with a small amount of SPU supply required by 2039. Note, only SPU reliable supplies (i.e. with back-up power) are included in this analysis. The City currently purchases wholesale supply from SPU to address operational challenges in providing supply to some areas of the system. The following section addresses considers supplying each operating area to evaluate and address these challenges, if necessary.

CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 06 6-24 | MAY 2021 | FINAL 6.13 Operational Water Supply Planning The City’s supplies and pump stations were evaluated to ensure adequate capacity is available to serve future demands. The City’s criteria identified in Chapter 2 is to provide sufficient reliable sources / pumps to provide the MDD for each operational area with the largest pump or source out of service. This section describes the capacity of the existing system and system recommendations to meet the City’s criteria. 6.13.1 Operational Areas For the purpose of evaluating supply and pumping capacity, the City’s water distribution system was divided into seven different operational areas, which feed a total of 16 pressure zones. Table 6.7 summarizes the various operational areas and their associated pressure zones. Figure 6.1 provides an overview of the City’s operational areas and pressure zones.

The emergency sources are identified in this section, but not included in the analysis tables. The supply and pumping capacity of each operational area was compared to the projected MDD for planning years 2019, 2029, and 2039. Demands were developed for this Plan in Chapter 3. The following sections summarize results for each operational area identified above. Results are summarized in the following sections. 6.13.2.1 Valley 196 Operational Area The Valley 196 Operational Area sources and source capacities are outlined in Table 6.8. The total reliable supply capacity of the Valley Operational Area is 15,150 gpm. Well PW-8 is the largest source capacity within the Valley Operational Area, bringing the total reliable capacity with the largest pump / supply capacity offline to 11,650 gpm. In addition to serving the Valley 196 Operational Area, the Valley sources also provide source capacity to all the higher zones with the exception of the West Hill 495 Operational Area. For this analysis, the West Hill 495 Operational Area is assumed to be served by the Dimmitt BPS and the SPU Bow Lake Intertie as described in Section 6.5. Note, emergency supplies to Kent through PRV 25 and to Coal Creek through PRV 53 were not considered in this analysis.

CHAPTER 06 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 6-29 The total reliable source / pump capacity of the West Hill 495 Operational Area is 2,400 gpm. Pump 3 at the West Hill BPS is the largest pump within the Operational Area, bringing the total reliable capacity with the largest pump / supply capacity offline to 1,400 gpm. In addition to the West Hill 495 Operational Area demands, the Operational Area sources must also provide source capacity for Skyway Wholesale. A comparison of the projected MDD and the source capacity for the West Hill 495 Operational Area is presented in Table 6.11 and demonstrates that there is sufficient capacity to meet the MDD in the West Hill 495 Operational Area in 2019, 2029, and 2039.

The City has sufficient supply to serve its customers with solely its own supplies, with the exception of the West Hill 495 Operational Area. The City needs to rely on its interties with SPU in the West Hill 495 Operational area to provide the MDD demands in the planning period. As discussed above the predicted range in time that the City’s annual water rights will meet demand is large, whether or not Well PW-5A is available as a source affects that predicted range. The City will pursue several different approaches to supplement its peak demand requirements (20-year and longer planning period). This includes expanded conservation efforts and strategies, additional storage, the purchase of wholesale water from SPU, perfecting additional Qi water rights (Maplewood Wells), and the possible use of other technologies such as reclaimed water and aquifer recharge. The City actively participates with other water systems on regional planning, supply, and operating issues. For example, the City is a member of the East King County Regional Water Association and the Water Conservation Coalition of Puget Sound. Another example is the City’s participation in the recent Puget Sound Regional Water Supply Outlook Study, which assessed the supply sources of the Central Puget Sound Region, explored ways that systems can support each other, and evaluated regional supply options to meet future needs. Under the City’s new contract with SPU, the City will be participating in the Seattle Regional Supply System (SRSS) via its attendance and participation at SRSS Operating Board meetings. CHAPTER 06 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 6-35 6.13.4 Regional Water Supply Issues The City draws its supply, primarily from aquifers in the lower reaches of the Cedar River Watershed. The Cedar Valley Aquifer in particular is relatively shallow. However, there is no evidence from studies conducted to date that the City’s water use has an impact on flows in the Cedar River. The Muckleshoot Indian Tribe has an interest in the Cedar River and its fishery resources. The Tribe is concerned with low stream flows that can affect water quality. The City is monitoring the river as a condition of its water rights and will continue to cooperate with the other parties in the management of this resource. SPU is the regional water purveyor for much of King County. It serves most of the cities and water districts in the vicinity of the City. The City itself has agreements with Seattle for supply as already discussed. In recent years, SPU has implemented a successful conservation program that has delayed the need for new sources. The water utilities in the Puget Sound Region have individually and collectively addressed future sources of supply to meet their future needs. SPU has constructed a 120-mgd water filtration plant on its Tolt River source. This improvement in water quality meets current water quality standards and allows SPU to make better use of the Tolt River source to meet existing and future demands. The City of Tacoma is the regional system to the south, serving much of Pierce County and some areas in south King County. Tacoma has completed construction of its second supply project. This involves a second supply pipeline from its Green River source which adds another 60 cubic feet per second of supply to the Tacoma system. The Tacoma Second Supply Project serves a number of water districts in south King County, some of which are also supplied by SPU. See: http://www.mytpu.org/tacomawater/water-system/supply/regional-water-supply/Default.htm The Growth Management Act (GMA) requires cities in Washington State to prepare 20-year plans for their future development, including the provision of adequate water supply to support this growth. This has raised concerns with many water utilities because they are often not consulted when the land use planning and economic development decisions are made for GMA and many water systems are reaching the capacity of their sources and don’t have the necessary future capacity to meet GMA projections. In addition, the process of obtaining water rights in Washington State has become extremely difficult and time-consuming because of concerns over instream flows and the suspected influence of groundwater withdrawals on stream flows. The current situation has prompted water systems in the Central Puget Sound area to pursue new source development as a top priority. The Cascade Water Alliance was created several years ago with participation of many of the water systems in King County to pursue new regional supplies as an alternative, or in conjunction with SPU and Tacoma. Many of the same systems have also participated in the Puget Sound Outlook Study, which included water utilities in King, Pierce, and Snohomish Counties. As a result of planning by individual water utilities and the efforts of the consortiums mentioned in the previous paragraphs, a number of regional projects have been proposed. The following list describes two of these regional solutions: • The Cascade Water Alliance has purchased water rights formerly held by Puget Sound Energy for hydroelectric generation on the White River, including storage in Lake Tapps and is currently working to get approval to use Lake Tapps as a municipal water supply. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 06 6-36 | MAY 2021 | FINAL • The Snohomish River Regional Water Authority acquired a 36-mgd water right formerly used by Weyerhauser (S1-10617C) for its now abandoned plant in Everett. Various schemes have been proposed for delivering this water to utilities, including some in King County. Use of the water right continues to be under study. The water supply situation is continually changing with alternatives proposed, studied, and sometimes put on the shelf. A number of other alternatives have been considered including the North Fork Tolt River, Snoqualmie Aquifer under the Middle Fork of the Snoqualmie River, the North Fork Snoqualmie River, direct withdrawal from Lake Washington, and even sources as far away as the Skagit River. At the present time, none of these appear to be in serious contention as the next source due to water rights or environmental, cost, or institutional issues. As a participant in forums proposing new supplies, the City is keeping itself involved and informed of new developments. It will make decisions and act as appropriate to preserve its current supply and/or to participate with other utilities in new or alternative source development. 6.14 Recommended Water Supply Improvements Recommended improvement projects for water supply can be grouped into the main areas of interties and reliability. Specific projects associated with the supply projects are included in Chapter 9. It is recommended that the City maintain and/or renew its existing intertie agreements with adjacent utilities. The City does not anticipate applying for any new water rights or changes to its existing water rights, no new well is recommended. The City will utilize its reservoirs and interties with SPU to supply peaking demands. System reliability can be improved through several approaches that include security and system redundancy. Security upgrades are incorporated into water facilities projects when appropriate. Ongoing security program costs are included in the City’s CIP. As redevelopment occurs, the City can improve system reliability by considering options for new PRVs and other control valves that provide additional supply to zones. Additional possible projects for improving supply reliability are aquifer recharge and the use of reclaimed water. The City has not investigated artificial aquifer recharge but plans to proceed with a study within the next 20 years to look at the feasibility of such a project. The use of reclaimed water has been attempted by the City with limited success to date. Feasible alternatives for using reclaimed water are not anticipated within the next 10 years. The City has completed the King County Water Reclamation Evaluation Checklist, which is provided as Appendix I. CHAPTER 07 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 7-1 Chapter 7 SYSTEM ANALYSIS 7.1 Introduction This chapter summarizes potential future system deficiencies in the City of Renton’s (City) water distribution and recommends improvements to the system. Carollo Engineers, Inc. (Carollo) evaluated the capacity of the pipelines using the City’s updated and calibrated hydraulic model. Evaluations of the remaining utilities were conducted in Microsoft Excel. Improvements identified in this chapter are summarized in the Capital Improvements Plan (CIP) in Chapter 9. 7.2 Operational Areas and Distribution System Assumptions To evaluate storage and pumping capacities, the City’s water distribution system was divided into 7 different operational areas that contain 16 pressure zones. The City is currently in the process of implementing major distribution system improvements and changes to pressure zones. These improvements are either under design, in construction, or being operationally implemented. This new infrastructure and changes to the distribution system were assumed to be implemented for the purpose of the system analysis. Improvements included the following: • Construction of the new Highlands 445 Reservoir. • Decommissioning of the existing Highlands 435 Pressure Zone (PZ). • Creation of the Highlands 445 PZ (formerly Highlands 435 PZ). • Construction of the new Kennydale 308 Reservoir. • Creation of the Kennydale 308 PZ (formerly Kennydale 320 PZ). • Extension of the Highlands 445 PZ boundary. Figure 7.1 shows the distribution system and pressure zone boundaries used for the system analysis. This base map figure is different from the existing system figure in Chapter 3, which consists of infrastructure that existed until June 2018. The calibration of the hydraulic model also accounts for the system as of June 2018, instead of the system analysis infrastructure presented in Figure 7.1. Figure 7.2 illustrates the hydraulic profile for the system analysis, which includes all improvements stated above.

The following section describes four components of storage, summarizes the existing system’s capacity to meet the storage needs of each operational area, and makes recommendations to address any identified storage deficits. 7.3.1 Components of Storage Water storage volumes are comprised of five components: • Operational storage. • Equalizing storage. • Standby storage (SS). • Fire-suppression storage (FSS). • Dead storage. Figure 7.3 schematically shows these components. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 07 7-8 | MAY 2021| FINAL Figure 7.3 Illustration of Storage Components 7.3.1.1 Operational Storage Operational storage is the volume of water used on a day-to-day basis to supply the water system while the sources of supply are in the “off” position. This volume is dependent on the sensitivity of the water level sensors controlling the pumps and is designed to prevent the pump motors from excessive starts and stops (cycling). Summarized in Table 7.2, the operational storage volume for the City’s reservoirs were determined from the hydraulic model’ supply sources on and off settings.

Note: Abbreviation: psi - pounds per square inch CHAPTER 07 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 7-9 South Talbot Reservoir – 1.5 MG 7.3.1.2 Equalizing Storage Equalizing storage is the total volume needed to satisfy the peak hourly demands (PHD) that exceed the supply system’s capacity. The State of Washington Administrative Code (WAC) 246-290-253 requires that equalizing storage provide peak demands. Furthermore, WAC 246-290-230 (5) states as such: New public water systems or additions to existing systems shall be designed with the capacity to deliver the design PHD quantity of water at 30 pounds per square inch (psi) (210 kPa [kilopascals]) under PHD flow conditions measured at all existing and proposed service water meters or along property lines adjacent to mains if no meter exists, and under the condition where all equalizing storage has been depleted. PHD is calculated using hourly demand data from the season of highest water consumption. For this plan, hourly demand data during the two-week period from July 1, 2018 to July 20, 2018 was averaged for each hour of the day for each operational area. The demand value for the hour of highest demand was considered PHD, while the average of the 24-hourly demands was the maximum day demand (MDD). Table 7.3 shows the PHD for each pressure zone based on peaking factor developed from Supervisory Control and Data Acquisition (SCADA) data recorded and hourly Advanced Metering Infrastructure (AMI) data provided by the City.

Fire flow demand is the quantity of water required for firefighting as defined by applicable water system criteria and fire codes. Firefighting often places the largest demands on a water system because a high volume of water must be supplied over a short time. Such demands require each component of the system to operate at its optimal condition. With that being said, the FSS level depends on maximum flow rates and duration. Water systems must have storage reservoirs that can meet fire flow requirements while maintaining 20 psi throughout the distribution system. Table 7.6 outlines the required maximum fire flow, duration, and FSS volume for each operational area.

Storage volume is considered dead if it’s located below the outlet pipe and cannot be used because of system hydraulic limitations or if it cannot be used because of water-quality problems associated with the volume in this lowest portion of the tank. One other major cause of dead storage in storage tanks is customer elevations. Water levels in tanks cannot be lowered more than 20 psi at the highest customer in the zone served by the tank. Figure 7.4 shows the elevation of the highest customer served by each reservoir. Table 7.8 summarizes the dead volume calculations for each reservoir.

Recommendations for operational areas that require storage improvements are offered subsequently in Section 7.3.3. 7.3.2.1 Valley Operational Area Storage for the Valley Operational Area is contained within the North Talbot and Mt. Olivet Reservoirs, which have a combined total storage volume of 7.89 MG. According to the highest customer elevation, the available storage at 20 psi is 5.76 MG combined for the Valley. Table 7.9 summarizes the storage analysis for the Valley. As shown in the analysis presented in Table 7.9, this area has sufficient storage through 2039 to serve its customers at 20 psi. However, the operational and equalizing storage must be available at a minimum of 30 psi for the highest resident served. The total available reservoir volume available at 30 psi is only 0.36 MG, which is 0.88 MG less than what is required in 2029 and 0.91 MG less than what is required in 2039.

According to the highest customer elevation, only 0.81 MG is available to the distribution system customers at 30 psi. The West Hill Reservoir also provides fire suppression storage and standby storage for Skyway based on the existing agreement with Skyway (Appendix D). It was assumed that no two simultaneous fires will occur in the West Hill 495 Operational Area and Skyway so the maximum fire flow requirement between the City and Skyway was considered. Table 7.10 summarizes the storage analysis for the West Hill 495 Operational Area. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 07 7-16 | MAY 2021| FINAL With the existing reliable sources and reservoirs, this area does not have sufficient storage through 2039. The City currently operates the tank with a 16 ft operational band, which has a 0.22 MG operational storage volume (as shown in Table 7.10).

These reservoirs have a total capacity of 7.59 MG. According to the highest elevations in the operational area, Highlands 445 has a total available storage of 6.97 MG at 20 psi but only 2.58 MG at 30 psi. Table 7.11 summarizes the storage analysis for the Highlands 445 Operational Area. With the existing reliable sources and reservoirs, this area has sufficient storage through 2039.

According to the highest customer elevations, available storage in the Highlands 565 equates to 1.20 MG at 30 psi and 2.20 MG at 20 psi. Additionally, because of significant headloss to some of the customers with high fire flow requirements, dead storage was increased by 16 feet. Table 7.12 summarizes the storage analysis for the Highlands 565 Operational Area. Even with the existing reliable sources and reservoirs, this area does not have sufficient storage for all planning years until 2039 and will be by 1.26 MG in 2029 and 1.65 MG in 2039.

Table 7.13 summarizes the storage analysis for the Rolling Hills 590 Operational Area. Like the Highlands 565 Operational Area, the Rolling Hills 590 Operational Area also does not have sufficient storage for all planning years until 2039. Existing storage is limited to 0.3 MG and required emergency and fire flow is four-times larger than the size of the tank providing water to the zone. Additional storage is required in this operational area.

The identified storage deficits can be mitigated by constructing additional storage or making changes to the operational strategy. In some cases, small improvements to the existing infrastructure, such as adding backup power to provide reliability, can better alleviate the storage deficiencies than adding storage. All recommended projects are summarized in the sections below. 7.3.3.1 Valley Storage Recommendation Storage analysis showed that although this area has sufficient storage at 20 psi, the Valley is deficient for all planning years until 2039 in supplying operational and equalizing volumes at 30 psi to the highest customers. As mentioned before, to address this issue, the City is connecting high-elevation residents within the Valley 196 PZ to higher pressure infrastructure. These improvements will then provide adequate operating pressures and fire flow pressures to these high-elevation residents. 7.3.3.2 Highlands 565 Storage Recommendation The Highlands 565 Operational Area does not have sufficient storage for all planning years until 2039. Excess storage located in the Highlands 445 Operational Area is sufficient to offset deficiencies in Highlands 565. A backup power generator is recommended at the Monroe Avenue booster pump station (BPS) to allow storage to be provided from the Highlands 445 PZ to the Highlands 565 PZ, which will also improve pumping capacity in the long term. The City is already planning on adding a generator at Monroe BPS as part of constructing a new 6.3-MG reservoir in the Highlands 445 PZ. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 07 7-20 | MAY 2021| FINAL 7.3.3.3 West Hill 495 Storage Recommendation Even with the existing reliable sources and reservoirs, the West Hill 495 Operational Area does not have sufficient storage through 2039. Excess storage located in the Valley Operational Area is sufficient to offset deficiencies in the West Hill 495. The Valley Operational Area has 1.04 MG of excess storage available by 2039, which can be reliably pumped to the West Hill 495 Operational Area via the new West Hill BPS. The City is currently planning on expanding capacity of the West Hill PS and adding a generator at the West Hill BPS as part of the West Hill BPS Improvement Project. Additionally, the City currently operates the tank with a 16 ft operational band, which equates to a 0.22-MG operational storage volume. It is recommended that the City update operational strategy and reduce the operational band thus decreasing the operational volume and helping to mitigate deficiencies. 7.3.3.4 Rolling Hills 590 Recommendation As shown in the storage analysis, the Rolling Hills 590 Operational Area does not have sufficient storage for all planning years, being deficient by 0.95 MG by 2039. The City has a few options to mitigate this deficiency: • Add backup power to the Maplewood BPS to increase pumping capacity from the Rolling Hills 490 PZ to the Rolling Hills 590 PZ, and add auto-start, auto-transfer, and backup power to the Rolling Hills BPS so that three pumps can be operated at the same time. • Construct a new 1.5-MG standpipe for the Rolling Hills 590 Operational Area, replacing the existing 0.3-MG tank. 7.4 Distribution System Analysis The calibrated InfoWater model of the City’s distribution system was used to analyze the system for future planning years, and projected system demands were added for the 2019, 2029, and 2039 planning years. The hydraulic model was used to evaluate typical system conditions during diurnal operations and fire flow availability. Then, the model was updated and calibrated for both extended period simulation with temporary pressure loggers and steady state with hydrant flow tests. CHAPTER 07 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 7-21 Fire Hydrant Test – June 2018 Pressure Recording Equipment used during field testing Model calibration uses fire flow tests intended to stress the City’s distribution system by creating a differential in pressure in the system. Pressure recording devices and pressure loggers were used to record pressures throughout the system during the flow tests CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 07 7-22 | MAY 2021| FINAL Hydrant Set-up for one of the fire flow tests Flow Management during fire flow tests Appendix P summarizes the calibration field plans and testing locations while Appendix Q details the model update and calibration steps and calibration results. Flowing water was typically routed to the closest stormwater catchments. Dechlorination equipment was used by City crew. City crew used diffusers with flow readings to record flowing flow at the hydrants during each test. CHAPTER 07 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 7-23 7.4.1 Evaluation Criteria Chapter 5 discussed system policies and criteria in detail. Key parameters evaluated with the model were for the system pressure criteria during normal operations and fire flow testing of the system. During normal operations, the minimum pressure as set by the DOH during MDD and PHD was 30 psi at the service meter. The City’s goal is to provide a maximum of 110 psi at the service meter. The Building Code requires individual pressure-reducing valves (PRVs) to be installed by property owners when the meter pressure exceeds 80 psi. 7.4.1.1 Land-Use-Based Fire Flow Requirements Table 7.16 summarizes the required fire flow and duration of this flow according to land use.

This approach allows the sources, pumps, and tanks to operate as their SCADA and controls are set. Using the criteria presented in the section above, the hydraulic model provides both maximum pressures and minimum pressures under ADD and PHD conditions, respectively. Figure 7.6 shows the nodes with maximum pressures for ADD outside of the planning criteria in 2020. Planning years 2029 and 2039 showed similar results but was not included in this chapter. Although the City has no maximum pressure requirement, system pressure above 80 psi (in yellow) and 110 psi (in orange) are identified for informational purposes. As seen in Figure 7.7, many high pressures exist in the system. Some of the pressure zones cover large-elevation ranges, leading to high pressures at lower elevations. In addition, BPSs commonly discharge into pressure zones near the bottom of a hill, forcing flow to the tank through the distribution system. This requires the hydraulic grade line (HGL) at the bottom of the hill to be higher than the tank overflow level at the top of the hill. In turn, this boosts the pressure in the lower elevations even higher during pumping than under static conditions as proven by tank overflow and meter elevation. The City completed a rezone evaluation in 2015 that identified potential rezoning improvements to reduce the range of pressures in each zone by creating additional pressure zones. The City is still in the process of reviewing and deciding on the best action plan based on the rezone evaluation results. Figure 7.8 identifies nodes with pressures lower than 30 psi during PHD. These results are for planning year 2039, which corresponds to the worst-case scenario with the highest demands. Of the low-pressure nodes (below 30 psi), some exist adjacent to the Springbrook transmission line. The City has been working on moving the customer connections to this line to the adjacent higher-pressure line. The model results had other low-pressure nodes near reservoirs; these nodes were excluded in the evaluation as service connections do not exist according to City staff. ?æ ?Å ?ç LakeBoren LakeDesire Lake Youngs ShadyLake PantherLake LakeWashington Last Revised: February 15, 2021 pw:\\IO-PW-INT.Carollo.local:Carollo\Documents\Client\WA\Renton\10899A00\Data\GIS\Fig7-6_MaxPressureduring2020ADD_RPUpdate.mxd CHAPTER 07 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON Figure 7.7 Maximum Pressure under ADD Condition inPlanning Year 2020 ADD without Improvements O 0 3,0001,500 Feet Disclaimer: Features shown in this figure are for planning purposes and represent approximate locations.

One segment of piping was found to exceed the velocity criteria in every planning year: this 8-inch line is located at Maple Valley Highway and Interstate 405 (I-405), where velocity reaches 9.5 fps, as shown in Figure 7.9. This section of pipe is surrounded by 12-inch pipes. Figure 7.9 Maximum Velocity in Planning Year 2039 without Improvements 7.4.4 Fire Flow Analysis Fire flows are typically the largest flows a system experiences and often a major factor in pipe sizing and network configurations. Using the fire flow test feature, the hydraulic model tested the fire capabilities at the 27 large fire locations. Specifically, it systematically simulated a fire at each model node representing a fire hydrant for each of the planning years. All system nodes with service connections were tested for a minimum pressure of 20 psi during the point fire demands. Table 7.18 summarizes the available fire flow at these locations in both 2029 and 2039. Figure 7.10 shows the low-pressure node results from the fire flow analysis for the large fire locations. All of the locations have adequate fire flow available, except for one location at Northeast of S Carr Rd. and Talbot Rd. S. The model was also used to perform a general system-wide fire analysis at 1,000 gpm and 3,000 gpm, testing all system nodes with service connections for 20 psi in both 2029 and 2039. Figure 7.11 shows nodes that do not meet the 20-psi requirement during required fire flows. Areas of particular susceptibility were dead-end mains, areas of older 4-inch and 6-inch asbestos cement (AC) piping networks, and areas near high elevation points in a pressure zone.

Improvements include actions such as pipe upsizing, main looping, and modifying pressure zone boundaries. Each of the recommended improvements requires a further site-specific and project-level engineering analysis before implementation. Recommendations are summarized by type of improvement in the following sections. 7.4.5.1 Projects to Address Low Peak-Hour Pressure Some low-pressure nodes (below 30 psi) exist adjacent to the Springbrook transmission line. The City has been working to remove connections to this line and relocate them onto an adjacent higher-pressure line. The model also found other low-pressure nodes near reservoirs; however, these nodes were excluded in the evaluation as City staff indicated that service connections do not exist at these sites. Figure 7.12 shows the location of piping improvements to address remaining low-pressure nodes (see project PZ-01). 7.4.5.2 Projects to Address Excessive Velocity One 8-inch line located at Maple Valley Highway and I-405 was found to exceed maximum velocity in the distribution system. This section of pipe is surrounded by 12-inch pipes and is recommended to also be upsized to 12-inch. Project D-13 will upsize 70 ft of 8-inch to 12-inch. 7.4.5.3 Improvements to Address Fire Flow in Non-Dead-End Areas Deficiencies identified in Section 7.4.4 and shown in Figure 7.10 require improvements to address fire flow deficiencies. The projects include upsizing 4-inch and 6-inch pipes and changing hydrant lateral connections. Detailed information on each recommended pipe improvement can be found in Table 7.19, where individual projects may be referenced based on Project Identification. Once implemented, these projects will eliminate the identified deficiencies. Figure 7.13 shows the recommended improvements to address fire flow deficiencies in areas that do not include dead-end pipes. ?æ ?Å SPU Station #33 Springbrook SpringsTreatment Plant Springbrook SpringsInfiltration Galleries Bow LakePipeline SPU Station #34 Fred Nelson BPS Kent Intertie South TalbotReservoir WTPPZ-02Last Revised: February 08, 2021 \\io-fs-1\Data\GIS\GISBackup\Renton\WaterSystemPlan2017\Fig7-11_LowPress_Rec_Imp.mxd CHAPTER 07 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON Figure 7.12 Low Pressure Recommended Improvements O 0 1,000500 Feet Disclaimer: Features shown in this figure are for planning purposes and represent approximate locations.

It is recommended that the City evaluate each case individually to determine how fire flows can be provided to each customer. In some cases, a customer may be protected by multiple hydrants on different water mains. As long as the total fire flow from the multiple hydrants meets the fire flow requirement, no improvements are necessary in these cases. In other cases where only one water main serves the customer, looping may be required or the dead-end main may need to be upsized to 12-inch to meet the fire flow requirements. Figure 7.14 identifies the location of dead-end pipes that cannot meet their fire flow requirements of 3,000 gpm. 7.4.5.5 Dead-End Pipes in Single-Family Areas The City also has multiple older 4-inch and 6-inch dead-end pipes in single-family areas that do not have the capacity to provide the City’s fire flow requirements of 1,000 gpm. It is recommended that the City evaluate each case individually to determine how fire flows can best be provided to each customer. The City has been programmatically moving hydrants from the dead-end to the closest main with 1,000 gpm. It is recommended that the City continue with this approach. Figure 7.15 identifies the location of dead-end pipes that cannot meet their fire flow requirements of 1,000 gpm. !W(!W( !W( !W( !W(!W(!W(!W(!W( !W( !W( X7 X7 X7 WTP WTP WTP UUTUUT UUT UUT UUT UUT UUT UUT UUT UUTUUT UUT UUTUUT UUT XÚXÚXÚXÚ XÚXÚ XÚXÚ XÚXÚ XÚXÚXÚXÚ XÚXÚXÚXÚ XÚXÚXÚ XÚXÚXÚ XÚXÚXÚ XÚXÚXÚXÚ XÚ XÚXÚXÚ XÚXÚXÚXÚXÚXÚ !5 !5 !5 !5 !5!5 !5 !5 !5!5 !5!5 !5 !5!5 !5 !5 !5 !5!5 !5 !5 !S(!S( "5 "5"5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5"5 "5 "5"5 "5"5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 "5 East Valley RdRainier Ave NS 133rd St Oakesdale Ave SWBenson D r S SW 7th St 140th Ave SEN E S u n set Blvd §¨¦405 Map l e V a l l e y H w y 164th Ave SESE Jones Rd Lake Youngs Service RdSE May Valle y R d Union Ave NESE Petrovitsky Rd Rolling HillsReservoirs 490 (3 MG)and 590 (0.3 MG) Springbrook SpringsInfiltration Galleries Springbrook SpringsTreatment Plant South Talbot Reservoir Kent Intertie TukwilaIntertie Bow LakePipeline SPU Station #33 SPUStation#34 FredNelsonBPS North Talbot BPSNorth TalbotReservoir Tiffany Park BPS RollingHills BPS MaplewoodChlorinationFacilityMaplewoodClearwell MaplewoodBPS PW-12 PW-11PW-17 Mt OlivetReservoir& BPS MonroeAvenue BPS WD 90Intertie HouserWay BPS RW-1,2 & 3 Renton/Seattle IntertiePW-8 PW-9EW-3RBoeing PlantMeter - Eastand West West HillReservoirDimmit BPS SkywayWholesale West Hill BPS Highlands BPS Highlands 6.3 MG445 Reservoir Highlands0.75 MG565 Reservoir Hazen Reservoir PW-5A Coal Creek Intertie PW-4 SouthTalbot BPS SPU Station #39 Kennydale 308Reservoir ?æ ?Å ?ç LakeBoren LakeDesire Lake Youngs ShadyLake PantherLake LakeWashington Last Revised: February 08, 2021 \\io-fs-1\Data\GIS\GISBackup\Renton\WaterSystemPlan2017\Fig7-13_Dead_End_Pipes_NonSF.mxd CHAPTER 07 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON Figure 7.14 Dead-end Pipes in Non-Single Family Areas O 0 3,0001,500 Feet Disclaimer: Features shown in this figure are for planning purposes and represent approximate locations.

The limiting capacity analysis uses the methodology described in DOH Water System Design Manual (2009) Worksheet 6-1 and Table 6-1. Table 7.20 describes the method used to calculate capacity for each component. Table 7.20 Limiting Capacity Calculations Water System Component Equation / Notes Sources (ADD) N = 𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅 𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑅𝑅 𝐶𝐶𝑅𝑅𝐶𝐶𝑅𝑅𝑆𝑆𝑅𝑅𝐶𝐶𝐶𝐶𝐴𝐴𝐴𝐴𝐴𝐴 𝐸𝐸𝑅𝑅𝐸𝐸 𝑣𝑣𝑅𝑅𝑅𝑅𝑆𝑆𝑅𝑅 where Reliable source capacity = capacity of sources with backup power or generators Sources (MDD) N = 𝐹𝐹𝑅𝑅𝑆𝑆𝐹𝐹 𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑅𝑅 𝐶𝐶𝑅𝑅𝐶𝐶𝑅𝑅𝑆𝑆𝑅𝑅𝐶𝐶𝐶𝐶𝑀𝑀𝐴𝐴𝐴𝐴 𝐸𝐸𝑅𝑅𝐸𝐸 𝑣𝑣𝑅𝑅𝑅𝑅𝑆𝑆𝑅𝑅 where Firm source capacity = source capacity with largest source (Well 1) offline Treatment The City has designed treatment capacity with sufficiency capacity to serve its sources.

Transmission Assumed to be addressed as part of source and pumping capacity. Note: Abbreviation: ERU – Equivalent Residential Unit; gpd/ERU – gallons per day per Equivalent Residential Unit. The capacity of many water system components can be expressed as the number of ERUs that can be served. As described in Chapter 3, an ERU for the City’s system is one that consumes 160 gallons per day (gpd) on an average demand day. On a maximum day, an ERU consumes 288 gpd. These values do not include distribution system leakage. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 07 7-58 | MAY 2021| FINAL To determine how many ERUs the City’s sources can serve on a maximum demand day, the supply to each operational area was divided by the MDD ERU value of 288 gpd. The MDD ERU value was also used to calculate the capacity of the City’s equalizing storage in ERUs. The ERU capacity of standby storage was calculated by subtracting out each tank’s equalizing storage and operational storage under 2039 demand conditions from its total available storage capacity. The capacity of each operational area is either limited by source supply or standby storage. None of the service areas are limited by the amount of equalizing storage available. In total, based on sources, equalizing storage, and standby storage, the District’s water system has a limiting capacity of approximately 89,160 ERUs. This is shown in Table 7.21. As presented in Chapter 3, the City predicts serving approximately 60,860 ERUs in 2039. Considering sources, equalizing storage, and standby storage, the City’s water system is anticipated to have sufficient capacity to meet expected growth within the 20-year planning period. Fire suppression storage is not a function of ERUs and therefore is not represented in Table 7.21. Table 7.21 Calculated Capacity in ERUs for Each Water System Component Water System Component System-wide 2039 ERU 60,860 Sources(1) 104,480 Treatment 104,480 Equalizing Storage 247,860 Standby Storage(2) 89,160 Limiting Capacity 89,160 Notes: (1) Does not include SPU’s interties used for summer peaking supply. (2) Standby Storage available was calculated by subtracting 2039 required equalizing storage and operational storage from available storage above the 20 psi HGL. 7.6 Pipeline Condition Evaluation 7.6.1 Methodology The pipe condition evaluation incorporates two types of data: remaining useful life (RUL) and maintenance-identified projects. As outlined in Section 7.5.3 below, the RUL analysis examined the pipe’s material, installation year, and material’s useful life to determine the year in which each pipe would reach its RUL. The pipes identified in this analysis serve as a starting point for the pipeline condition evaluation. Additional pipeline condition projects have been identified by the City’s Maintenance Department based on field observation, excessive maintenance, and staff general experience. These projects, in addition to the RUL analysis projects, make up the pipeline condition evaluation. CHAPTER 07 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021| 7-59 7.6.2 Maintenance Projects The City’s Maintenance Department identified nine water-main replacement projects, prioritizing them according to City needs, maintenance history, pipe age, and pipe type. Many of these projects overlap with RUL projects and projects identified by the hydraulic model. Table 7.22 summarizes these projects, while Figure 7.16 shows their locations in the system.

The length of time that a pipe is anticipated to remain functional is called useful life. Useful life depends largely on the pipe material but can also depend on soil conditions, water constituents, and methods of installation. When a pipe is in service beyond its useful life, the increasing costs of maintenance associated with a failing pipe typically warrant replacement. Table 7.23 presents the estimated useful life of various types of pipe materials found in the City’s pipe data. Table 7.23 Useful Life Assumptions by Pipe Material Pipe Material Useful Life Assumption (years) Asbestos-Cement (AC) 50 Cast iron (CI) 80 Copper (COP) 50 Ductile iron (DI) 100 Galvanized iron (GI) 50 Galvanized steel (GS) 50 High-density polyethylene (HDPE) 50 Polyvinyl chloride (PVC) 50 Stainless steel (SSTL) 50 Steel (STL) 50 RUL is defined as the length of time left before a pipe will reach the end of its useful life. Pipe age and material type, derived from the City’s geographic information system (GIS) data, were used to determine the RUL of the pipes. Approximately 0.03 percent of the pipes have unknown installation dates. Table 7.24 presents the total length of piping according to the year installed and material type. The majority of the system is cast iron and ductile iron. Cast iron was primary installed between 1900 and 1979. Ductile iron installation started slowly in the 1960’s and became the predominate pipe material installed by the 1970’s. The cells of Table 7.24 are color-coded to show the RUL of pipes in each category. For example, the lengths of pipe in the red cells have all reached the end of their useful life, meaning they have an RUL of zero. Using these assumptions, approximately 122,000 linear feet (LF) of pipe or 7.4 percent of the City’s pipes have an RUL of 10 years or less. Furthermore, approximately 9.0 percent of the City’s pipes are expected to reach the end of their useful life in the next 20 years. Figure 7.17 shows the total length of pipe reaching the end of its assumed useful life for each year for the next 100 years, starting in 2019 and ending in 2119. All pipes that have already exceeded their useful life are shown in the year 2019. If the City wished to start annually replacing all its pipes from 2019 to 2119, approximately 16,600 LF of piping must be replaced each year, shown as the dashed black line on the figure. If the City wishes to start annually replacing pipes that will reach their RUL within the 20-year planning horizon, approximately 7,000 LF of piping must be replaced each year. This is shown as the orange line on the figure. The City is recommended to continue its annual pipe-replacement program and replace approximately up to 7,000 LF per year, targeting the pipes that have reached the end of their useful life and to offset the depreciation of this City asset. Figure 7.18 presents the locations of these pipes.

The Water Maintenance Services Unit (Services Unit) is led by Gregg Seegmiller and conducts the following tasks: • Main flushing. • Tank and reservoir cleaning. • Exercising of valves and hydrants. • Leak detection and repair. • PRV maintenance and setting. • Small meter maintenance, repair, and calibration. • Hydrant maintenance and repair. • Tie-in of water main extensions. The Water Utility Maintenance Unit (Maintenance Unit) is led by Craig Pray and is responsible for the operation, maintenance, and repair of the pump stations, pressure reducing valves (PRVs), wells, treatment systems, treatment plants, and supervisory control and data acquisition (SCADA) system. This unit also samples water quality for operations and regulatory compliance. 8.1.2 Preventive Maintenance Preventive maintenance is performed by both City staff and contracted private parties. For example, maintenance and calibration for large meters are contracted out, whereas painting of pump station components is usually performed by City staff. Large maintenance projects (e.g., elevated tank painting) is done through Public Works contracts with contractors selected under public bidding rules. These projects are usually managed by the Water Utility Engineering Section of the Utility Systems Division. The City’s preventative maintenance program is detailed later in this chapter in Section 8.3.5. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 08 8-2 | MAY 2021 | FINAL 8.1.3 Field Engineering Field engineering support is supplied by both City staff and contracted private parties such as engineering consultant firms. 8.1.4 Water Quality Monitoring The Maintenance Unit conducts water quality monitoring for both operations and regulatory compliance. Operational practices monitor chlorine, fluoride, turbidity, temperature, phosphate, iron, manganese, ammonia, hydrogen sulfide, pH, well water levels, and well production rates. Compliance water quality monitoring is required by the Federal Safe Drinking Water Act of which most requirements are administered by the Washington State Department of Health (DOH) and are published in State of Washington Administrative Code (WAC)-246-290. This practice monitors volatile organic chemicals, synthetic organic chemicals, disinfection byproducts, inorganic chemicals, physical parameters, bacteriological, radionuclides, and lead and copper (via customer tap sampling). The City systematically checks its network of groundwater monitoring wells to detect and prevent contaminants in the aquifers from reaching the production wells. Water table levels in the aquifers are also monitored. Except for those of coliform monitoring sampling and monthly fluoride meter calibration check sampling, all test results of compliance monitoring are stored in the City’s enterprise-wide database. This database also stores results of monitoring for aquifer contamination and water level data collected by a portable sounder. Water level and water temperature data collected by an automated sounder is stored on one of the City’s network servers. More information on the City’s records and reports can be found later in this chapter in Section 8.9. 8.1.5 Emergency Response The City’s Comprehensive Emergency Management Plan (CEMP) defines how the City will respond to emergencies. This plan is maintained by the City’s Emergency Management Section. As a sub-plan to the CEMP, the Water System Emergency Response Plan includes information on the system’s security and methods of response to various terrorism threats. The Water Maintenance Manager prepares for and responds to emergencies involving the drinking water system, while the Maintenance Services Division maintains an emergency call-up list for employees on standby to respond to emergencies after hours on weekdays, on weekends, and on holidays. The response to an emergency may vary from a single maintenance technician addressing a relatively minor problem to the City activating the Emergency Operations Center and calling on the state or federal government to lead the response to a large disaster or terrorism incident. The Water System Emergency Response Plan is detailed later in this chapter in Section 8.6. 8.1.6 Cross Connection Control Most potential cross connections are identified during the plan review and building permit review processes. Specifically, the Water Utility Engineering Section and the Development Engineering Section work together to identify potential cross connections when reviewing the CHAPTER 08 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 8-3 plans for proposed development projects. Then, the Cross Connection Control (CCC) Specialist in the Water Utility Engineering Section works with the Development Engineering Section’s building inspectors to ensure that identified cross connections are either eliminated or are controlled through installed backflow prevention assemblies. The CCC Specialist maintains records on the City’s enterprise-wide database, noting information about particular cross connections and the backflow prevention assemblies that are installed (e.g., installation and test history). The database also generates test notices to send to the owners of the backflow prevention assemblies. The City uses XC2 Software LLC’s, XC2 software, to input information, query information, and generate reports, including those test notices from the database. Members of the Water Maintenance Services Section, Water Utility Engineering Section, Development Engineering Section, and Building Section remain alert of cross connections as they go about their duties throughout the City and its built environment. If cross connections are discovered, they are reported to the City’s CCC specialist. Appendix L presents the City’s Cross Connection Control Plan. 8.1.7 Capital Improvement Planning The Water Utility’s capital improvement plan (CIP) is implemented by its Engineering Supervisor, who works closely with the Water Maintenance Manager to identify and prioritize CIP projects. Most selected improvements are completed by public-bid contracts. Chapter 9, Capital Improvement Plan, details this information further. 8.1.8 Budget Formulation The Water Utility Engineering Supervisor formulates the budget for the Water Utility’s CIP while the Water Maintenance Manager formulates the O&M budget. To formulate their budgets, both work closely with their division directors and the Public Works’ Principal Financial and Administrative Analyst, who then works with the Finance Division’s staff to formulate the complete Water Utility budget. 8.1.9 Response to Complaints Complaints and questions are fielded by members of both the Water Utility Engineering Section and Water Maintenance Services Section. All water quality complaints are forwarded to the Maintenance Services Division’s secretary at (425) 430-7400. The Water Maintenance Services Section log, respond to, track, and follow-up with said complaints. Further information on the City’s Customer Complaint Response Program can be found later in this chapter in Section 8.8. 8.1.10 Public and Press Contact The City’s Communications Director or their representative handles contact with the media. The Development Services Division mans a customer service counter on the sixth floor of City Hall. Members of the Water Utility Engineering Section often report to this counter to assist customers with questions about water quality and water service availability. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 08 8-4 | MAY 2021 | FINAL 8.1.11 Billing The Utility Billing Division of the Administrative Services Department handles customer service, billing, and revenue collections for the Water Utility, as well as for the Wastewater Utility and Surface Water Utility. 8.2 Operator Certification The City’s water system serves a population of greater than 50,000, thus is classified as a Class 4 distribution system. Considered a Class 3 purification plant by the Association of Boards of Certifications, the Maplewood Water Treatment Plant (WTP) completes the following processes: • Treats water by removing iron and manganese using green sand filtration. • Treats water using fluoride and sodium hydroxide. • Converts hydrogen sulfide to sulfate through the addition of oxygen in conjunction with catalytic conversion of granular activated carbon. • Removes ammonia by reacting it with chlorine to convert it to nitrogen gas. Other treatment in the system includes in-line fluoridation, in-line chlorination, and the addition of sodium hydroxide and ortho-polyphosphates to inhibit the internal corrosion of water mains and private plumbing. These treatment systems are not considered purification plants. The requirements of WAC 246-292 are as follows: • The City’s water system must be managed by a Water Distribution Manager (WDM) 4. • The Maplewood WTP must be operated by a Water Treatment Plant Operator (WTPO) 3 or higher. • Wells RW-1, RW-2, and RW-3 must be operated by a Basic Treatment Operator or higher. • The CCC Program must be managed by a CCC Specialist. The City meets or exceeds all of these requirements. Table 8.1 lists the certifications of the drinking water staff. As the City’s water system becomes increasingly complex, its staff must be trained to efficiently to keep up with advancements in technology and ever-expanding federal and state regulations. New employees require utility orientation and basic information while experienced employees need training in regulatory requirements and technological updates. In-service training consists of special courses and seminars specifically designed for operation and maintenance groups. The training is offered through organizations like the American Water Works Association, Pacific Northwest Section; Evergreen Rural Water Association; Washington Environmental Training Center; equipment vendors; and local colleges, universities, and trade organizations. The City supports and promotes operator training. CHAPTER 08 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 8-5 Table 8.1 Staff Certification Name Certification George Stahl WDM4 (Mandatory certifications for the operation of the water system) Craig Pray WDM4, WTPO3 (Mandatory certifications for the operation of the water system) Gregg Seegmiller WDM3 Jason Burkey WDM1 Sean Campbell WDM3 Mark Combs WDM2 John Dimond WDM1 Charles (Greg) Durbin WDM3, WTPO2 Joe Ferrer WDS Jayson Gallaway WDM1 Todd Hamblin WDM1 Danny Hribal WDM3, WTPO3 Joel McCann WDM1 Joshua O’Neill WDM4, WTPO3 Patrick Pierson WDM2 James Rodriguez WDM1 Tyler Schwartzenberger WDM1, WTPO1 Mick Holte WDM4, CCS Eric Ott WDM4 Note: Abbreviation: WDS - Water Distribution Specialist. WTP operation requires an on-call staff 24 hours a day, 7 days a week. The City currently has five WTP staff members. To allow for more staffing flexibility, training or hiring an additional licensed WTP operator is recommended. This licensed staff member can also perform other duties for the utility. In addition, additional maintenance staff may aid the City in conducting additional routine preventative maintenance activities that are currently being deferred due to lack of resources. Additional operators beyond the recommendations would allow the City to expand activities, such as acoustic leak detection of the distribution system and perform a consistent flushing program. 8.3 System Operation and Control The following sections review the water system’s routine operation practices conducted by staff, performance evaluation, operations under abnormal conditions, and preventative maintenance program that manages the condition and operations of all the Water Utility’s major components and assets. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 08 8-6 | MAY 2021 | FINAL 8.3.1 Identification of Major System Components Chapter 2 - Existing System details the major components of the water system including wells, treatment plants, interties, pump stations, PRVs, reservoirs, and piping. 8.3.2 Routine System Operation 8.3.2.1 General System Operation In general, the water supply is produced in the Valley 196 Pressure Zone (PZ) and is pumped to reservoirs on the surrounding hills. The majority of customers are located in the valley or on the hill pressure zones, which have reservoirs. Customers in the intermediate pressure zones are served through PRVs from higher pressure zones. Chapter 2 provides additional detail on system operations. Supply is generated by City-owned wells. Wholesale supply provided by Seattle Public Utilities (SPU) addresses system operational challenges in the Bow Lake Area (PRV 24) and on West Hill. Additional SPU interties are used for emergencies. 8.3.2.2 Start-up and Shut-down Procedures Each major system component has an O&M manual that describes start-up and shut-down procedures and safety procedures. Additionally, the City has written procedures for both electrical and hydraulic lock-out and tag-out of the water system facilities. 8.3.2.3 Meter Reading In October 2011, the City installed an Automated Meter Infrastructure (AMI) System. The AMI allows City staff to remotely read water meters. Meters are typically read remotely by the Utility Billing Division for purposes of billing. The Maintenance Services Division and Utility Engineering Divisions can also access meter readings for operational purposes or to support a capital project. In addition to reading usage, the City uses AMI meters to alerts customers about potential leaks. The Maintenance Services Division operates and maintains the AMI meters (e.g., addresses communication errors, calibrates large meters, etc.). Meanwhile, the City’s Information Technology Division operates and maintains the information technology resources needed to maintain the AMI system. 8.3.2.4 System Control All sources and pump stations are metered, and the SCADA system monitors and records all their flows, as well as the flow through the metered connections to the SPU pipelines at the Fred Nelson Booster Pump Station (BPS), Tiffany Park BPS, and Bow Lake Pipeline. In addition to the information recorded by the SCADA system, Water Maintenance Services staff read and record meter readings at all sources and pump stations daily if the facility is in operation and twice a week if the facility is on standby. New telemetry using Ubiquiti technology is planned to be implemented for the Water Utility and other utilities in the next 5 years. The City currently contracts Emerson programmable logic controller (PLC) from California but plans to upgrade the PLCs to Allen Bradly and maintain consistent configuration of PLC ports across all stations. For operational reasons, the City prefers to own its fiber communications where practical and cost-effective. CHAPTER 08 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 8-7 8.3.3 System Performance Evaluation System performance is evaluated by its ability to meet federal and state drinking water quality requirements, maintain customer satisfaction, control cost production and delivery of water, and meet system policy goals for service pressure and fire flow. 8.3.4 Operation during Abnormal Conditions City operators are trained and experienced to operate the water system during abnormal conditions such as a power outage or equipment failure. The City has multiple approaches to maintain reliability during such abnormal conditions: • Using redundant infrastructure and equipment to reduce effects to customers during abnormal conditions, e.g., the City has a redundant pump in each BPS and multiple PRVs for all PRV-fed pressure zones. • Applying maintenance best practice (as resources allow) such as conducting preventative maintenance and keeping spare parts and pipe on hand. • Keeping standby power available for key water facilities to continue providing service during power outages: as discussed in Chapters 2 and 9, the City plans to install on-site backup power generators at additional water system facilities. • Maintaining emergency interties with four adjacent utilities to provide supply when needed. • Maintaining emergency storage in its reservoirs, which can be distributed to the entire system by gravity through redundant PRVs. 8.3.5 Preventive Maintenance Program The preventive maintenance program is documented and tracked by CityWorks, a computer-based system that schedules preventive maintenance, assign resources to where they will be most valuable, predicts equipment reliability problems and prevent them from happening, and manages assets to best meet the organization’s goals. The following section explains how various components of the City’s water system are addressed by the preventative maintenance program. 8.3.5.1 Pipelines Pipeline repair and replacement (R&R) is planned and performed by the City’s Utility Services Division. The current distribution mains are generally in good condition. Pipes reaching the end of their usable life are identified and repaired or replaced based on the City’s available resources. 8.3.5.2 Reservoirs Reservoirs act as storage and regulating devices for water flow, and maintaining them in prime physical condition is essential for any water distribution system. Operators control and monitor reservoirs through the SCADA system. Additionally, operators conduct visual checks regularly for evidence of vandalism, forced entry, or damage and control functionality. The reservoirs are maintained on a periodic basis through weekly, quarterly, and annual activities. Periodic reservoir replacement is recommended to maintain a reliable water system. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 08 8-8 | MAY 2021 | FINAL 8.3.5.3 Wells and Pump Stations Reliable service from the City’s wells and pumps stations is key to producing and transmitting water to customers. Operators control and monitor wells and pump stations through the SCADA system. As previously discussed, WTPs associated with the wells are staffed on-site by certified operators who conduct visual checks regularly for evidence of vandalism, forced entry, or damage and control functionality. These facilities are maintained on a periodic basis including weekly, quarterly, and annual activities. Periodic replacement is recommended to maintain a reliable water system. 8.3.5.4 Pressure Reducing Valve Stations PRV stations allow distribution systems to transfer water from higher pressure zones to lower pressure zones without exceeding the allowed pressures in the lower pressure zones. Water is transferred through a valve that reduces the pressure to a specified pressure setting. Every month, Water Maintenance Services staff inspects the City’s PRVs. These inspections are supplemented by a more thorough inspection conducted by a contractor that specializes in PRVs to determine which stations need to be rehabilitated or upgraded. Maintenance on the PRVs is conducted by City staff. The Services Unit replaces the parflex tubing and fittings on all of the PRVs annually, and completely rebuilds typically 10 valves each year. According to the rebuild schedule, PRVs are typically rebuilt every 5 years. 8.3.5.5 Backup Power To maintain system operations during an unforeseen power outage, backup power to critical communications elements and sites is desirable. Currently, the City runs and periodically maintains on-site standby generators to keep them in good working order. 8.3.5.6 Hydrants Fire hydrants supply water for fire protection and other purposes. The City’s hydrants are tested annually to check if they can provide available fire flow in the event of an emergency. The inspection also improves water quality since, during this practice, stagnant water that is purged from the hydrant stubs. A follow-up inspection 2 weeks after testing is recommended to listen for potential leaks. Maintenance of the hydrants includes replacement or rebuilding of older hydrants, rust removal, and painting or repainting hydrants. Hydrants replaced on 4-inch diameter mains are made with lower-capacity, 2-inch diameter ports that limit flow and do not have a hard connection. These ports prevent a pumper truck from drawing a vacuum and collapsing the pipes. With its current funding, the City currently replaces 10 hydrants per year. An increase in funds would allow the City to replace more hydrants per year. Painting hydrants is mostly handled by City staff with the exception of the South Renton neighborhood. The City received grant funding in 2019 for a public arts campaign for community artists to paint murals on 20 City-owned fire hydrants. 8.3.5.7 Meters The City uses data from AMI meters to monitor unusual changes in amounts of water, which indicate potential leaks. According to the manufacturer, the City’s AMI system (Sensus), including CHAPTER 08 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 8-9 system components and batteries in the radios, is anticipated to have a 20-year life. Thus, meter replacement is currently set on a 20-year program to coincide with the AMI system’s end of life. Large meters are calibrated according to the manufacturer recommendations. 8.3.5.8 Valves The City inspects its valves twice a year, at least annually. As part of the inspection, blow offs and airvacs are inspected as well. 8.4 Sanitary Survey From the last survey in 2012 the following were addressed: Table 8.2 Sanitary Survey Summary – Completed and On-going Actions Task Completed? Document routine inspections of reservoirs with photos Completed for 2012 survey Modify external overflow pipelines at each reservoir to incorporate an air gap and screen/flapper valve On-going Install inverted screen well vent on Well EW-3R, PW-11, and PW-17 Completed Check integrity of Springbrook springs gasket seals on collection box hatches Completed Identify Springbrook springs collection box overflows and screen them to keep out potential contaminants. Completed Submit a Stage 2 Disinfection by Product (DBP) Monitoring Plan to DOH Completed Consider raising well PW-12 S15 above ground Completed Provide a watertight seal on the North Talbot Reservoir access hatch Completed Groundwater Rule Compliance Monitoring Completed A sanitary survey was conducted in 2017. From the 2017 survey, all recommended actions were completed; with one remaining on-going: Table 8.3 Sanitary Survey Summary – Recommended Actions in 2017 Survey Task Completed? Highlands 1.5 MG Concrete Reservoir. Clean out insects and debris. Seal crack in the concrete. Completed North Talbot Reservoir. Ensure there is a seal between inner rim of gutter and lid. Completed Please document routine inspection of reservoir with photos. Completed Modify external overflow pipelines at each reservoir to incorporate an air gap and screen/flapper valve On-going Continue to label tanks and plumbing in treatment plants and booster stations. Completed Review and update sources listed on the water facilities inventory. Completed CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 08 8-10 | MAY 2021 | FINAL 8.5 Equipment, Supplies, and Chemical Listing The City has vehicles and major equipment assigned to the Water Shop. Inventoried supplies (items stocked on shelves or stored in the yard) are purchased and tracked by the Maintenance Services Division. In addition to stock items, a list of vendors is maintained for parts and equipment items that are not stocked on the shelf or in the yard because they aren’t purchased or they are large in size. The Water Maintenance Manager maintains information regarding service representatives for major water system components and chemical suppliers. Additionally, the Water System Emergency Response Plan contains lists of contacts for suppliers and support services. Both the Water Maintenance Services Section and the Water Utility Engineering Section maintain copies of O&M manuals for all major components of the water system. These manuals list manufacturer part numbers and descriptions as well as technical specifications for components and chemicals used. 8.6 Emergency Response Program As mentioned earlier, the Water Utility maintains a Water System Emergency Response Plan, which is a sub-plan to the City’s CEMP. 8.6.1 Water System Personnel Emergency Call-up List The Water Maintenance Services Section publishes two emergency call-up lists: one for emergencies dealing with wells and pump stations and one for emergencies dealing with water mains, PRVs, and reservoirs. The SCADA system is connected to an auto-dialer that contacts call-up personnel when an alarm is triggered after office hours. The auto-dialer is programmed to move down a list of phone numbers until its call is acknowledged. After-office-hours calls to 911 that are related to the water system are handled by the 911 dispatcher who then contacts a cell phone that is carried by on-call staff. If the on-call staff does not answer the cell phone, the dispatcher will attempt to contact the Water Maintenance Manager, the Water Maintenance Services Supervisor, or the Water Utility Maintenance Supervisor. Other phone numbers are available to the dispatcher including the Maintenance Services Director’s cell phone number. 8.6.2 Notification Procedures – Water Quality Emergencies See Appendix N, Drinking Water Quality Monitoring Program. 8.6.3 Vulnerability Analysis As required by the Public Health Security and Bioterrorism Preparedness and Response Act of 2002, the City’s Water Utility completed a security vulnerability assessment in December 2003 and updated the city-wide CEMP in October 2017. The Water Utility budgets for such security improvements through its CIP. Typically, this money is transferred into specific project budgets when security upgrades are incorporated into the overall project scope. Chapter 5, Policies, Criteria, and Standards, further details for the Water Utility’s reliability and vulnerability policies. Periodically, the Water Utility assesses the vulnerability of its drinking water system to threats from earthquakes, floods, power outages, etc. CHAPTER 08 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 8-11 New facilities are designed and constructed to the latest building code standards. In addition, extra emphasis is placed on hazard engineering when the new facilities are critical to the operation of the water system. Meanwhile, retrofits of existing facilities typically incorporate security and safety upgrades and sometimes structural modifications to enhance survivability and operability of the facility after natural or manmade disasters. The Water Utility designs and constructs redundancy in its water main network, supply sources, booster pumps and PRV stations, and other facilities to increase the system’s overall reliability and reduce its vulnerability to disruptions. America's Water Infrastructure Act of 2018 (AWIA) requires community water systems serving more than 3,300 people to develop or update risk assessments and emergency response plans. The risk and resilience assessment must be completed, and certification submitted to the United States Environmental Protection Agency by December 31, 2020 for systems serving between 50,000 and 99,999 people, and it must be repeated every 5 years. 8.6.4 Site Security Site security is necessary to protect the City’s assets at each facility site. Surveillance cameras are recommended at all of the facilities. The City plans to explore opportunities for grants from Homeland Security to aid in funding the cameras. In addition, the City plans to seek partnerships with the local Fire and Police departments to install higher quality cameras on several reservoirs, which would provide a wider view of the City for emergency personnel. In these cases, it is anticipated the Fire or Police departments would fund the cameras at the facilities. 8.7 Safety Procedures The goal of the Water Maintenance Services Section is to comply with all Occupational Safety and Health Administration (OSHA) and Washington Industrial Safety and Health Act of 1973 (WISHA) regulations applicable to the operation of the section. All workplace hazards, related safety and first aid equipment, and procedures are identified and communicated to the Water Maintenance Services staff through safety briefings, facility-specific standard operating procedures, facility O&M Manuals, and safety data sheets. 8.8 Customer Complaint Response Program Each year the Water Maintenance Services Section receives approximately 10,000 service requests, of which the majority are complaints in regard to water leaks and meter malfunctions. In 2018 there was a total of 7,150 requests and of that 177 requests were for meter inspections and 145 requests were to have large meters tested or repaired. Only a handful of water quality complaints are received each year and 99 percent of them are internal household plumbing issues. Each call is logged by customer service staff. When applicable, a staff member is assigned to the complaint. The following information is documented about the complaint: its location, the individual assigned to investigate and fix the problem, observations and discoveries in the field, what was done to address the complaint, and how much time and materials were expended. 8.9 Record Keeping and Reporting Maintenance and operating records are essential tools in utility management and operation that provide supporting data necessary for long-term planning. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 08 8-12 | MAY 2021 | FINAL The Water Utility keeps several types of records: • Water quality sampling for operations and mandatory water quality sampling records (see Appendix N): mandatory water quality sampling test results are reported to the state and maintained by the City. • Chemical dosing records. • Water main disinfection records. • Hydrant flushing records. • Source production and pumping records. • Reservoir level records. • Aquifer level records. • Personnel records. • Customer contact records. • Meter records. • Inventory records. The City’s records are legible, permanent, accurate, and accessible, and hard copies are maintained in the Water Maintenance Manager’s office. The Water Utility Engineering Section maintains records of backflow assembly test results, tester certifications, test notifications, backflow assembly information, and cross connection information in a database in the City’s enterprise database management system. Meanwhile, the SCADA system (described in Chapter 2) records the flow rates and flow quantities of all wells, booster pumps, and spring; water levels in reservoirs and production wells; levels in chemical storage tanks; pH levels of raw and treated water; pump starts and fails; alarm conditions; and other data. Current maps of the water system are available electronically in an ESRI ArcGIS platform. Maps are available to the Water Maintenance Services Section, the Fire Department, Development Services Division, and other departments. Geographic information system (GIS) data is periodically updated as required. On the other hand, paper forms of the maps including valve, hydrant, and fire flow map books at 1 inch = 400 inch scale and wall maps at various scales are available upon request. Maps are also available in PDF format. All records are kept in accordance with Revised Code of Washington (RCW) and WAC requirements. The City’s file maintenance plan outlining specific instructions for keeping and destroying files is maintained and managed by the City Clerk. 8.10 O&M Summary The City’s water system is well operated and maintained, meeting or exceeding its statutory requirements. The evaluation of O&M practices identified the following potential improvements: • Train or hire an additional water treatment plant operator for operational flexibility. • Additional resources, if available, could allow expansion of preventative maintenance and replacement activities. CHAPTER 09 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 9-1 Chapter 9 CAPITAL IMPROVEMENT PLAN 9.1 Introduction This chapter combines the various projects recommended in the Water System Plan (Plan) for the City of Renton (City) water distribution system and presents them as a comprehensive Capital Improvement Plan (CIP). With this CIP, the City will have a guideline to plan and budget for the water system over the next 20 years, as well as the recommended timing and cost estimates for each identified project. Project phasing is described as either short term (0 to 10 years, which corresponds to 2020-2029) or long term (10 to 20 years, which corresponds to 2030-2039). The City has a separate Capital Investment Plan that prioritizes all City projects and identifies funding plans for a 6-year period. The City updates the budget for the Capital Investment Plan every 2 years. As part of the planning and development of the capital improvement plan, the water utility will continue to consider programs and projects to support the City’s business plan, vision and mission for economic growth, social equity, and environmental sustainability goals. The water utility will continue to implement capital improvement projects in a transparent manner, informed by system and community needs and the financial, environmental, and social costs and benefits, to provide long-term community value. Appendix R details each project with cost estimates and detailed implementation timing and prioritization. 9.1.1 Capital Project Categories The Plan’s CIP projects are categorized by the following infrastructure: • Distribution pipeline(D). • Pressure Zone (PZ). • Storage Facilities (ST) • Annual Repair and Replacement (R&R) Programs (P). • Pump Station (PS). • General and On-Going Capital Projects and Programs (G). • Regulatory Compliance Programs (R). The abbreviations presented above were used during project identification to delineate each project category. The City’s Water Main Replacement Annual Program (WM) consist of the replacement of aging and undersized water mains throughout the water distribution and transmission system. The prioritization and selection of pipes are based on several factors including degree of fire flow deficiencies identified from the hydraulic model, frequency of leaks and breaks, remaining useful life of the pipes, and coordination with other City capital projects. This program reduces the CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 09 9-2 | MAY 2021 | FINAL likelihood of system failures, unplanned service interruptions, and claims for damages against the City. The following project categories identified in this Plan will be ultimately included in the City’s WM Program: • Distribution Pipeline Projects (D), which consist of sited specific projects to help mitigate deficiencies identified in Chapter 7, and sited maintenance main projects. • Annual R&R Programs (P), which included non-sited pipelines. The City will prioritize every year based on the City’s priorities and opportunities such as major roadways improvements and redevelopment areas. Pressure zone (PZ), storage (ST), and pump station (PS) projects are in their respective categories. Storage Projects include the construction of the new Highlands 445-reservoir, and Kennydale reservoir, the recommendation of a new reservoir in Rolling Hills 590 PZ and the Blackriver reservoir. Pump Station Projects include recommendations at West Hill, South Talbot, Monroe, Mt Olivet Pump Stations. Meanwhile, general projects (G) include studies and seismic-related projects for the distribution system, and on-going capital projects and programs, such as security improvements, or pressure-reducing valve (PRV) rehabilitation. Finally, regulatory (R) projects represent general water quality compliance projects, water system plan updates, and water conservation program. An overview of the City’s recommended CIP is presented in Section 9.2. 9.1.2 Capital Project Types To support the City's financial evaluation, CIP projects were allocated into three types: 1. Capacity: Projects that add system capacity to meet future demand growth. These projects are typically funded with connection fees and are recommended to meet the analysis criteria detailed in Chapter 7. 2. Improvement: Projects that increase the level-of-service (e.g., redundant pumping, backup power, pipe upsizing, fire flow, system reliability) of existing infrastructure. These projects are typically funded with rates and are needed whether demand increases or stays the same. 3. R&R: Projects that replace or maintain existing infrastructure without increasing capacity or level-of-service. These projects are typically funded with reserves and are meant to renew infrastructure that is in poor condition. Individual projects may include elements of multiple capital project types, meaning that each project was defined as one or more of the three types and assigned a percentage of the total project cost to each type. The allocations between multiple types were made using professional judgment. 9.2 CIP Program Overview This section summarizes the CIP program and illustrates the locations of recommended projects, both specific and programmatic. Tables 9.1 and 9.2 summarize the CIP projects by project category and priority, respectively. Figures 9.1 and 9.2 summarize the percent of each project identified by project category and project type, respectively. Specific project details are provided at the end of the chapter in Table 9.15. CHAPTER 09 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 9-3 When considering CIP costs by project category as shown in Table 9.1 and Figure 9.1, the majority of CIP costs (47.3 percent) are accrued from programmatic projects. Distribution pipeline projects and general projects comprise the other high-cost categories and account for 17.3 percent and 10.4 percent of the CIP, respectively. When considering CIP costs by priority (more detail in Section 9.4) as shown in Table 9.2 and Figure 9.2, approximately 63 percent of the CIP costs are annual programs. The total water CIP cost over the next 20 years is approximately $124 million, which equates to approximately $6 million per year for the planning period. Of the total cost, approximately $28 million is budgeted for the short term, approximately $18 million is budgeted for the long term, and approximately $79 million is budgeted for the annual category.

These costs were determined using both Carollo Engineers, Inc. (Carollo) understanding of project locations and current conditions and the City’s costs of similar and recently constructed capital projects. Note, actual costs may vary from these estimates by -50 percent to +100 percent. All costs are in 2019 dollars. The Engineering News Report’s (ENR’s) U.S. 20-City Construction Cost Index for June 2019 is 11,268. As previously stated, the estimates are subject to change as the project design matures and because costs for labor, materials, and equipment may vary in the future. 9.3.2 Baseline Unit Cost Baseline construction costs were estimated using unit costs with the assumptions presented below. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 09 9-6 | MAY 2021 | FINAL 9.3.2.1 Pipeline Unit Costs Table 9.3 shows unit cost assumptions for pipelines provided by the City. These costs were developed from recent construction costs for various water pipeline projects and were rounded to the nearest tenth. To be conservative, these unit costs assume open-trench construction in improved areas. The estimated construction costs cover pavement-cutting, excavation, hauling, shoring, pipe materials, hydrants, valves, service lines and installation, backfill material and installation, and pavement replacement. The unit costs are for typical field conditions for construction in stable soil at depths ranging between three to five feet. Table 9.3 Pipeline Unit Costs Pipe Size (Inches) Pipeline Unit Cost(1) ($/LF) 8 $300 10 $350 12 $400 16 $500 18 $550 24 $700 Notes: (1) The unit cost does not include the additional 25 percent for construction contingency, 30 percent for design and admin. Abbreviation: LF – linear feet. 9.3.2.2 Pump Station Generator Costs Costs for pump station generators were developed based on Carollo’s and the City’s past experience with similar projects. Unit cost for generators was assumed to be $200,000 per 100 horsepower (hp). As presented in Table 9.4, pump station generator costs are based on pump horsepower. Table 9.4 Pump Station Generator Unit Cost Generator Size (hp) Generator Unit Cost(1) ($/hp) Any $200,000 Note: (1) The unit cost does not include the additional 25 percent for construction contingency, 30 percent for design and admin. 9.3.2.3 Storage Costs Project costs for new storage were developed according to typical costs from past City projects. Conceptual costs for reservoirs vary by type (ground, standpipe, or elevated) and are estimated based on reservoir volume in gallons (gal), as presented in Table 9.5. Storage costs are sensitive to site-specific geotechnical and seismic considerations; therefore, the City is recommended to conduct a reservoir siting study at the start of every new storage project. CHAPTER 09 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 9-7 Table 9.5 Reservoir Unit Costs Reservoir Type Storage Unit Cost(1) ($/gal) Ground $3 Standpipe $6 Elevated $8 Note: (1) The unit cost does not include the additional 25 percent for construction contingency, 30 percent for design and admin. 9.3.2.4 Pressure-Reducing Valve Costs Other costs for the CIP include that of the PRV station. The conceptual cost presented in Table 9.6 was estimated based on Carollo’s recent projects. Table 9.6 Valve Costs Cost(1) (Lump Sum) Pressure Reducing Valve Station $200,000 Note: (1) The unit cost does not include the additional 25 percent for construction contingency or 30 percent for design and admin. 9.3.3 Construction Contingency Contingency costs must be reviewed on a case-by-case basis because they will vary considerably with each project. Consequently, the preliminary layout of a project will contain uncertainties such as unexpected construction conditions, the need for unforeseen mechanical items, and variations in final quantities; because all these items increase project costs, allowances should be made for them in preliminary estimates. To assist the City in making financial decisions for these future construction projects, a construction contingency cost of 25 percent is added to the baseline construction cost. 9.3.4 Design/Admin Costs Design and administration costs include expenses associated with project engineering, professional services during the construction phase, and project administration. More specifically, engineering services associated with new facilities include the following tasks: • Conducting preliminary investigations and reports. • Preparing drawings and specifications during construction. • Surveying and staking. • Sampling of testing material. • Providing start-up services. Meanwhile, construction phase professional services cover items such as construction management, engineering services, materials testing, and inspection during construction. Finally, project administration costs cover items such as legal fees, financing expenses, administrative costs, and interest during construction. In general, the City suggested that the projects in this CIP include a design and administration cost of 30 percent of the construction cost with contingency. Per City’s direction, no specific planning contingency was added to the capital costs. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 09 9-8 | MAY 2021 | FINAL 9.3.5 Tot al Capital Improvement Cost The costs presented in this CIP are high-level planning costs that will help the City make financial decisions The sample capital improvement project cost calculation shown below demonstrates how construction contingency as well as design and administrative costs were added to the baseline construction cost to determine the total project cost. The construction contingency plus design and administration costs make up 38.5 percent ($625,000/$1,625,000) of the total project cost estimate. Example: Baseline Construction Cost $1,000,000 Construction Contingency (25%) $250,000 Estimated Construction Cost $1,250,000 Engineering Design Cost + Project Administration (30%) $375,000 Total Capital Improvement Cost $1,625,000 9.4 CIP Development and Implementation The capital improvement implementation was separated into two phases: • Short term: 0 to 10 years. • Long term: 10 to 20 years. The City developed prioritization criteria to prioritize all projects and recommendations from this Plan between Short-term and Long-term. Short-term projects have already started or are committed to starting within a reasonable timeframe and include high-priority projects, such as the following: • High priority multi-feature projects. • Projects improving system reliability. • Maintenance-identified projects. All other CIP projects, including single feature projects are long term. Table 9.7 summarizes the high-level prioritization matrix for different project types and purposes. Table 9.7 Overall Prioritization Criteria Project Types(1) 0-10 years 10-20 years Dead-end pipes in existing non-single-family areas (3,000 gpm): X Dead-end pipes in existing single-family areas (1,000 gpm): X Maintenance projects X Pipe upsize due to excessive velocity (over 8 fps) X R&R pipes only – past RUL Annual replacement $ R&R pipes only – reaching RUL 0-10 years R&R pipes only – reaching RUL 10-20 years Pipe upsize for fire flow only X Pipe upsize for fire flow, maintenance, and past RUL X CHAPTER 09 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 9-9 Project Types(1) 0-10 years 10-20 years Pipe upsize for fire flow, and RUL reached in 0-10 years X Pipe upsize for fire flow, and RUL reached in 10-20 years X Pressure Zone projects (PZ-02) X Pump Station projects (PS-01, PS-02, PS-03) X Note: Abbreviations: gpm – gallons per minute; RUL – remaining useful life; fps – feet per second. A detailed and customized scoring method using weighting factors was developed to help refine rankings and prioritize specific pipeline projects after the general method stated above. Appendix S details this scoring method. This detailed method resulted in the same project allocation between 0-10 years and 10-20 years as the simplified method presented in this section. This is an initial evaluation of the projects; however, it is recommended that the City develop a systematic method to prioritize projects, especially R&R projects The following sections summarize recommended projects identified in previous chapters and incorporated in the summary in Section 9.5. Figures and detailed tables are located at the end of this chapter. 9.4.1 Recommended Distribution Pipeline Projects Distribution pipeline projects (D) were developed using: • The hydraulic model and were identified for areas not meeting velocity and pressure criteria, as detailed in Chapter 7. • City staff input, specifically projects identified by the maintenance staff as areas of improvement. Projects identified under this category will be part of the City’s WM, which consists of the replacement of aging and undersized water mains throughout the water distribution and transmission system. The prioritization and selection of pipes are based on several factors including degree of fire flow deficiencies identified from the hydraulic model, frequency of leaks and breaks, remaining useful life of the pipes, and coordination with other City capital projects. This program reduces the likelihood of system failures, unplanned service interruptions, and claims for damages against the City. Pipelines identified under project P-03 (see section 9.4.3) will also be included in the City’s WM Program for funding purpose. 9.4.1.1 D-1 through D-14: Fire Flow Recommended Pipeline Projects To address fire flow deficiencies identified in Chapter 7, projects and recommendations presented in that chapter should be implemented. Namely, projects will upsize 4-inch and 6-inch pipes and change hydrant lateral connections. Once implemented, these projects will help mitigate the identified deficiencies. Section 9.5 details each fire flow pipeline project and references it according to its project identification. In the CIP, these are projects D-01 through D-14. Given the results of the remaining useful life analysis presented in Chapter 7, some of these projects are also recommended to address the asset condition. In summary, approximately 19,650 LF of piping is recommended to be upsized or built to mitigate fire flow deficiencies. These projects are estimated to total $10.06 million (including design and admin and construction contingency) and are recommended in both short-term and long-term phases, as shown in the Prioritization Criteria in Table 9.7. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 09 9-10 | MAY 2021 | FINAL 9.4.1.2 D-15: Velocity Improvement Projects One 8-inch line located at Maple Valley Highway and Interstate 405 (I-405) was found to exceed maximum velocity during peak hour demand (PHD) in the distribution system. This section of the pipe is surrounded by 12-inch piping and is recommended to also be upsized to 12 inches. This velocity improvement project will upsize 70 feet of 8-inch line to 12 inches and is listed as the Maple Valley Hwy Pipe Upsize at Henry Moses Aquatic Center (D-15) in the CIP. D-13 is estimated at $46,000 and recommended in the long term. It is anticipated that this deficiency will be corrected as part of the water main improvements required for a proposed commercial development of the old Stoneway Concrete site along Maple Valley Highway. 9.4.1.3 D-16 through D-22: Maintenance-Identified Condition Projects The City’s maintenance department identified nine water main replacement projects and prioritized them according to City needs, maintenance history, pipe age, and pipe type. In the CIP, they are projects D-16 through D-22 in detailed Table 9.15. Many of these projects overlap with RUL projects and projects identified by the hydraulic model. Per the City’s policies on new pipe sizes, existing pipes with 4-inch or 6-inch diameters are recommended to be upsized to 8 inches. Through these maintenance-identified condition projects, a total of approximately 21,660 feet of piping is recommended to be replaced for a total of $11.4 million. They are all recommended to be implemented in the short term. 9.4.1.4 Distribution Pipeline Recommendations Summary Table 9.8 summarizes the footage and the cost of different diameter piping that must be replaced in the short and long terms. This table includes all projects recommended in the above sections. Table 9.8 Distribution Pipelines Projects Summary Pipe Diameter 0-10 years 10-20 years Length (LF) Cost(2) Length (LF) Cost(2) 8-inch(1) 30,850 $15,041,000 3,350 $1,634,000 10-inch(1) -- -- 1,800 $1,024,000 12-inch(1) 5,210 $3,387,000 100 $391,000 Hydrant Lateral Connections -- -- 70 $34,000 Total 36,060 $18,428,000 5,320 $3,083,000 Notes: (1) Both 4-inch and 6-inch existing diameters will be replaced with larger-diameter pipes. (2) The cost includes 25 percent construction contingency and 30 percent engineer/legal/admin contingency. 9.4.2 Recommended Pressure Zone Projects This CIP has two pressure zone projects, both of which are summarized in Table 9.9 with their respective priorities and costs. Table 9.9 Pressure Zone Recommendations Project Number Project Name Priority Cost(1) PZ-01 HLD 445/565 Pipe Reconfiguration 10-20 years $325,000 PZ-02 VLY196 Re-zone 0-10 years $100,000 Note: (1) The cost includes 25 percent construction contingency and 30 percent engineer/legal/admin contingency. CHAPTER 09 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 9-11 9.4.2.1 PZ-01: HLD 445/565 Pipe Reconfiguration Several low-pressure nodes (below 30 pounds per square inch [psi]) exist adjacent to the Highlands 565 transmission line. The City has been working to relocate connections currently located on the lower-pressure line to adjacent higher-pressure lines. In addition, as this area gets re-developed, new developments must connect to the neighboring Highland 565 PZ due to fire flow deficiencies on the Highland 445 adjacent pipe. This pipe reconfiguration project is labeled HLD 445/565 Pipe Reconfiguration (PZ-01) in the CIP. PZ-01 is anticipated to be implemented in the long term and estimated at approximately $325,000. 9.4.2.2 PZ-02: VLY196 Re-Zone The storage analysis detailed in Chapter 7 showed that, although this area has sufficient storage at 20 psi, the Valley 196 PZ is deficient in its ability to supply operational and equalizing volumes at 30 psi to the highest customers. To address this issue, the City is connecting high-elevation residents within the Valley 196 PZ to higher-pressure infrastructure, thus providing them adequate operating and fire flow pressures. This project is labeled VLY196 Re-zone (PZ-02) in the CIP and, in addition to the re-zoning, includes improvement of hydrant S-00235 at 401 S 43rd St and Talbot Rd. More specifically, the hydrant needs to be re-zoned, decommissioned, or removed. PZ-02 is estimated at $100,000 and recommended to be implemented in the short term. 9.4.3 Recommended Annual Repair and Replacement Programs Two types of programmatic projects (P) are recommended: annual R&R pipeline projects and dead-end programs. 9.4.3.1 P-01: Dead-End Pipes in Non-Single-Family Areas Program The City has multiple 4-inch, 6-inch, or 8-inch diameter dead-end pipes in non-single family areas that are older and do not have the capacity to provide the City’s fire flow requirements of 3,000 gpm. In some cases, customers are protected by multiple hydrants on different water mains. As long as the total fire flow from the multiple hydrants meets the fire flow requirement, no improvements are necessary. In other cases where only one water main serves customers, looping may be required or the dead-end main may need to be upsized to 12 inches to meet the fire flow requirements. The City is recommended to individually evaluate each case of these dead-end pipes to determine how fire flow s can be provided to customers. These areas should be reviewed when new development takes place and potentially looped or upsized. No cost was developed for the annual Dead-End Pipes in Non-Single-Family Areas Program (P-01). 9.4.3.2 P-02: Dead-End Pipes in Single Family Areas Program The City has multiple 4-inch and 6-inch dead-end pipes in single family areas that are also old and do not have the capacity to provide the City’s fire flow requirements of 1,000 gpm. To address this situation, the City has been programmatically moving hydrants from the dead-end to the closest main with 1,000 gpm. The City is recommended to continue this approach and to also evaluate each case individually to determine how fire flows can best be provided customers. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 09 9-12 | MAY 2021 | FINAL The estimated cost for the Dead-End Pipes in Single Family Areas Program (P-02) is approximately $1.16 million and is recommended in the short term. 9.4.3.3 P-03: Pipeline Repair and Replacement Program As outlined in Chapter 7, the RUL analysis examined the pipes’ material and installation year, as well as their materials’ useful life, to determine the year during which each pipe would reach the end of its useful life. The City is recommended to continue its annual pipe-replacement program and replace approximately 6,000 LF of pipe per year, targeting pipes that have reached the end of their useful life and offsetting the depreciation of this City asset. Table 9.10 summarizes the footage and the cost for each pipe diameter that’s included in the CIP and also presents the total annual LF and cost. Additionally, it is recommended that the City invest in developing an Asset Management Program (AMP) to help prioritize which pipelines need to be replaced each year (see project G-11). Table 9.10 Remaining Useful Life Repair and Replacement Summary Pipe Diameter R&R Annual Program Statistics Total Length (LF) Total Cost(1) 6-inch and less 65,630 $ 26,662,000 8-inch 17,950 $ 8,751,000 10-inch 4,620 $ 2,628,000 12-inch 20,270 $ 13,176,000 14-inch 770 $ 563,000 16-inch 4,410 $ 3,583,000 18-inch 2,360 $ 2,109,000 24-inch 110 $ 125,000 Total 116,120 $ 57,597,000 Annual Length/Cost 5,806 $ 2,879,850 Notes: (1) The cost includes 25 percent construction contingency and 30 percent engineer/legal/admin contingency. (2) Linear feet in this table are different than the ones presented in Chapter 7. Some of the recommended R&R pipelines were also included as part of the specific sited Distribution Pipeline projects. Linear feet from these projects were removed from the Remaining Useful Life R&R in this table. P-03 is estimated to cost approximately $57.6 million or $2.9 million annually over the 20-year period. Note, the total linear feet of pipes in Table 9.10 differ from the analysis performed in Chapter 7. Some of the pipelines identified in the RUL evaluation were also included as part of the specific sited Distribution Pipeline projects (P-16 through P-22) and were therefore not included here. No specific projects were identified as part of the Pipeline R&R Program (P-03). Instead, the City is recommended to decide which pipes to replace every year. It is recommended that the City continues to enhance its asset management program to help prioritize and time the R&R of its aging water infrastructure by weighing the costs of continued maintenance against the costs of R&R. This will help prioritize which pipelines identified under Project P-03 need to be replaced each year and will include additional data than remaining useful analysis only. These plans CHAPTER 09 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 9-13 ultimately reduce operation and maintenance risks, thus resulting in overall lower costs burdened by ratepayers. Currently, the City wishes to focus on the pipelines located in the downtown and Highlands areas and take advantage of opportunities such as implementing projects in conjunction with major roadway improvements as much as possible. Water Main Improvements in conjunction with Major Roadway Improvements This program consists of taking advantage of major roadway improvements planned by the City in areas where pipeline reaching their remaining useful life were identified. This would include the design and construction of new water mains as part of major roadway improvements, including Rainier Avenue Phase 4, Duvall Avenue and water main relocation to accommodate the I-405 corridor improvement project by WSDOT. Water Main Improvements in Redevelopment Areas – Downtown and Highlands Redevelopment activities can have a substantial impact on the ability of the existing distribution system to provide sufficient water to customers for fire protection service and for domestic uses. Significant activities are planned during the S 2nd and S 3rd 2-way conversion anticipated in 2019 - 2022. Typically, detailed hydraulic models are used in conjunction with area water demand forecasts and fire flow requirements to identify potential water main improvements in redevelopment areas. Water main improvements needed for redevelopment projects are typically installed and paid for by the developers. The developers may recoup some of their costs from future benefitting properties by applying to City Council for a latecomer agreement. In some cases, with the approval of funding from the City Council, the City may install the improvements or participate in the cost of the improvements with the developers and the City recovers its costs from benefitting properties through a Special Assessment District. The pipe replacement program for redevelopment projects is designed to balance the City’s investments in pipe replacement projects to reduce risks associated with aging pipe infrastructure with investments in major pipe replacement projects to support growth and development. 9.4.4 Recommended Pump Station Projects Table 9.11 summarizes three pump station projects (PS), all of which are prioritized for the short term. Table 9.11 Pump Station Recommendations Project Number Project Name Priority Cost(1) PS-01 Monroe BPS 0-10 years $ 488,000 PS-02 West Hill BPS 0-10 years $ 1,842,000 PS-03 South Talbot BPS 0-10 years $ 2,175,000 Notes: (1) The cost includes 25 percent construction contingency and 30 percent engineer/legal/admin contingency. Abbreviation: BPS – booster pump station. 9.4.4.1 PS-01: Monroe BPS Project With the existing reliable sources and reservoirs, the Highlands 565 Operational Area does not have enough storage for all planning years until 2039. As described in Chapter 7, the Highlands 565 area will be deficient by 1.26 million gallons (MG) by 2029 and 1.65 MG by 2039. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 09 9-14 | MAY 2021 | FINAL However, excess storage located in the Highlands 445 Operational Area is sufficient to offset Highland 565 deficiencies. For the Monroe BPS Project (PS-01), the City is recommended to install backup power generators at the Monroe Avenue BPS to allow storage to be provided from the Highlands 445 PZ to the Highlands 565 PZ, which will also improve pumping capacity in the long term. The City is planning on adding a generator at Monroe BPS and is phased for the short term in the CIP. The total capital cost is estimated at approximately $488,000. 9.4.4.2 PS-02: West Hill BPS Project The West Hill BPS Project (PS-02) will install a generator at the West Hill BPS, increasing pumping capacity and implementing electrical, structural, and mechanical improvements. PS-02 is currently under design and, therefore, phased for the short term in the CIP. The cost is estimated at $1.8 million based on a 2018 pre-design study. 9.4.4.3 PS-03: South Talbot BPS Project The South Talbot BPS Project (PS-03) will replace fire and duty pumps in the South Talbot BPS and implement electrical, structural, and mechanical improvements. This project is currently under design and, therefore, phased for the short term. The cost is estimated at $2.2 million based on a 2018 pre-design study. 9.4.5 Recommended Storage Projects This section summarizes the recommended storage projects (ST) that were identified through the storage analysis detailed in Chapter 7. Table 9.12 shows the two recommended projects. Table 9.12 Storage Recommendations Project Number Project Name Priority Cost(1) ST-01 Rolling Hill 590 Storage (1.5-MG) 0-20 years $ 17,395,000 ST-02 West Hill 495 Storage 0-10 years N/A Operational change only Note: (1) The cost includes 25 percent construction contingency and 30 percent Engineer/Legal/Admin contingency. 9.4.5.1 ST-01: Rolling Hill 590 Storage Project As identified during the storage analysis, Rolling Hills 590 Operational Area does not have sufficient storage for all planning years until 2039. The analysis in Chapter 7 shows that the operational area will be deficient by 0.95 MG by 2039. The Rolling Hill 590 Storage Project (ST-01) will mitigate this storage deficiency in two phases: • Phase 1: Add backup power to the Maplewood BPS to increase pumping capacity from the Rolling Hills 490 PZ to the Rolling Hills 590 PZ, and add auto-start, auto-transfer, and backup power to the Rolling Hills BPS so that three pumps can be operated at the same time. • Phase 2: Construct a new 1.5-MG standpipe for the Rolling Hills 590 Operational Area. The new standpipe will replace the existing 0.3-MG elevated tank. CHAPTER 09 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 9-15 Phase 1 is recommended to be implemented in the short term and is estimated to cost approximately $2.8 million. Phase 2 is recommended to be implemented in the long term and is estimated to cost approximately $14.6 million. After both phases are implemented, the Rolling Hills 590 Operational Area will have sufficient storage for the future and added redundancy with reliable pumping from the Maplewood BPS and Rolling Hills BPS. Siting studies and property acquisition may be necessary for this project. Hydraulic analysis using the City’s updated hydraulic model is recommended to confirm reservoir sizing and system hydraulics. The new facilities and related pipelines will be designed and constructed in accordance to the latest seismic codes and standards. 9.4.5.2 ST-02: West Hill 495 Storage Even with the existing reliable sources and reservoirs, the West Hill 495 Operational Area does not have sufficient storage through 2039. Excess storage located in the Valley Operational Area is sufficient to offset deficiencies in the West Hill 495. The Valley Operational Area has 1.04 MG of excess storage available by 2039, which can be reliably pumped to the West Hill 495 Operational Area via the new West Hill BPS. The City is currently planning on expanding capacity of the West Hill PS and adding a generator at the West Hill BPS as part of the West Hill BPS Improvement Project. Additionally, the City currently operates the tank with a 16 ft operational band, which equates to a 0.22-MG operational storage volume. It is recommended that the City update operational strategy and reduce the operational band thus decreasing the operational volume and helping to mitigate deficiencies. 9.4.6 Recommended General and on-going Projects and Programs Eleven general projects (G) were recommended for this CIP and are summarized in Table 9.13. Table 9.13 Recommended General Projects Summary Project Number Project Name Priority 20-year Total Cost(1) G-01 Reservoir Repair, Painting, Cathodic Protection Annual $ 3,000,000 G-02 Emergency Response Water Projects Annual $ 2,000,000 G-03 Pump Station Condition Evaluation (mechanical, structural, electrical) 0-10 years $ 300,000 G-04 Storage Condition Evaluation (structural, seismic) 0-10 years $ 400,000 G-05 Security Improvements Annual $ 200,000 G-06 Telemetry System and SCADA Upgrades Annual $ 1,000,000 G-07 PRV Rehabilitation Annual $ 2,000,000 G-08 Improvements to pipelines on bridge Annual $ 4,000,000 Total $ 12,900,000 Notes: (1) The cost includes 25 percent construction contingency and 30 percent engineer/legal/admin contingency. Abbreviation: SCADA - Supervisory Control and Data Acquisition. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 09 9-16 | MAY 2021 | FINAL 9.4.6.1 G-01: Reservoir Repair, Painting, Cathodic Protection The Reservoir Repair, Painting, Cathodic Protection project (G-01) consists of a scheduled recoating of the interior and exterior surfaces of the existing steel standpipe and elevated tanks to extend the useful life of the structures. The project will also install seismic and safety upgrades and a cathodic protection system. The budget for this program is $150,000 per year for an estimated total of $3 million for the 20-year planning period. 9.4.6.2 G-02: Emergency Response Water Projects Under G-02, the City wishes to budget $100,000 per year for an estimated planning total of $2 million for any emergency response water projects that may arise or are currently unknown. 9.4.6.3 G-03: Pump Station Condition Evaluation The City is recommended to perform a condition evaluation of their existing pump stations in the short term. Any pump stations constructed before 1985 are anticipated to require replacement or repair within the planning period. The Pump Station Condition Evaluation (G-03) is estimated to cost $300,000. The outcome of this evaluation will result in pump station rehabilitation projects and recommend emergency power supply for the remaining pump station without emergency supply. This will result in the design and installation of upgrades and/or replacement of mechanical and electrical equipment, correcting deficiencies to pump buildings including the installation of backup power supply with auto-start transfer switches. The goal for these recommendations is to extend the useful life of the pump stations reduces the likelihood of pump failures and unplanned service interruptions for fire protection and for domestic uses. 9.4.6.4 G-04: Storage Condition Evaluation The City is recommended to also perform a condition evaluation of its existing storage reservoirs since those that were constructed before 1975 may need to be replaced, repaired, or recoated within the planning period. G-01 is included as a capital project for potential costs and necessary repairs resulting from this storage evaluation. The Storage Condition Evaluation (G-04) is a study recommended in the short term and $400,000 was allocated to this effort in the CIP. 9.4.6.5 G-05: Security Improvements This project plans, designs, and installs security improvements to the existing water system facilities according to findings and recommendations derived from the security vulnerability assessment. The budget for the Security Improvements program (G-05) is $10,000 per year for a total of $200,000 during the planning period. 9.4.6.6 G-06: Telemetry System and SCADA Upgrades This project systematically replaces the remote telemetry units (RTUs) in the City’s various water facilities. Currently, some replacement parts for the existing RTUs are unavailable and, in any case, the City should be prepared with replacement units should the original system’s manufacturers go out of business. This project also designs, reconfigures, programs, and conducts functional testing on the master telemetry unit (MTU) and the human-machine interface (HMI) in the City’s operation and maintenance headquarters. CHAPTER 09 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 9-17 The Telemetry System and SCADA Upgrades project (G-06) will occur on a 5-year cycle and is estimated to cost $50,000 per year for a total cost of $1 million during the planning period. 9.4.6.7 G-07: PRV Rehabilitation This program consists of the rehabilitation and replacement of 45 existing PRV’s throughout the system. The improvements include the verification of the sizing and set points of the PRV’s based on the hydraulic model analysis of the system, adequacy of pressure relief valves, metering, and integration with the City’s SCADA system. The replacement criteria and schedule will be determined based on a PRV rehabilitation and replacement study that will be completed the City by June 2020. The City is recommended to continue its PRV rehabilitation and maintenance program for its 45 PRVS, which are critical pieces of its distribution system. The PRV Rehabilitation project is budgeted $100,000 per year for an estimated total of $2 million for the planning period. 9.4.6.8 G-08: Improvements to Pipelines on Bridge This program consists of the replacement of existing water mains located under existing bridges that are going to be retrofitted as part of the City’s Transportation Division capital improvement plan. The City owns and maintains the following water mains on bridges: • One 12-inch water main on the Logan Ave N bridge. • One 8-inch water main on the Williams Ave S bridge. • Two 18-inch water mains on the Wells Ave S bridge. • One 8-inch water main on the Bronson Way S bridge. • One 16-inch water main on the Houser Way S bridge. • One 16-inch water main on the SW 43rd St bridge. • One 24-inch water main on the SW 43rd St bridge. The Improvements to Pipelines on Bridge project (G-08) evaluates the condition and seismic resiliency of these locations, as well as makes seismic improvements and repairs as necessary. This project is budgeted $200,000 per year for an estimated total of $4 million for the planning period. 9.4.7 Recommended Regulatory Compliance Projects Three regulatory Compliance projects (R) were recommended for this CIP and are summarized in Table 9.14. Table 9.14 Recommended Regulatory Compliance Projects Summary Project Number Project Name Priority 20-year Total Cost(1) R-01 Water Quality Compliance Projects Annual $ 4,000,000 R-02 Water Conservation Program Implementation Annual $ 4,000,000 R-03 Water System Plan 0-10 years and 10-20 years $ 800,000 9.4.7.1 R-01: Water Quality Compliance Projects A budget of $200,000 per year for regulatory compliance projects (R-01) is recommended to be set aside for an estimated total of $4 million for the 20-year planning period. CITY OF RENTON | WATER SYSTEM PLAN UPDATE | CHAPTER 09 9-18 | MAY 2021 | FINAL 9.4.7.2 R-02: Water Conservation Program Implementation As recommended in Chapter 4, the Water Use Efficiency (WUE) rule, given the number of connections the City has, requires the City to evaluate or implement efforts for nine measures of its choice. These measures support the City’s proposed goals for water use efficiency, in addition to the mandatory measures. The selected measures are as follows: • Water bill consumption history. • School outreach. • Utility bill inserts. • Natural yard care workshops. • Advertising and public outreach. • City demonstration garden. • WashWise washing machine rebates. • Hose gaskets. • Web page. A budget of $200,000 per year was allocated to the Water Conservation Program Implementation project (R-02) in the CIP for a total estimated cost of $4 million for the 20-year planning period. 9.4.7.3 R-03: Water System Plan The Water System Plan project (R-03) includes the development of 10-year and 20-year updates to the City’s Plan. Each plan is estimated to cost $400,000 for a total of $800,000 in the planning period. 9.4.8 Other Projects - Future Reservoirs to Increase Storage and Enhance Operational Flexibility The City can meet its future storage requirements by adding new reservoirs and replacing its existing reservoirs. To improve operational flexibility and redundancy in the distribution system, the City plans to install larger reservoirs in the future by maximizing their footprints within the current City-owned properties. These larger reservoirs will provide added reliability when the City needs to take an existing reservoir out of service for maintenance. These projects will need siting studies and property acquisition if necessary, hydraulic analysis and reservoir sizing, pre-design, final design and construction of storage facilities to increase storage in the water system operational areas to meet growth demand projection and to provide operational reliability and flexibility. The new facilities and related pipelines will be designed and constructed in accordance to the latest seismic codes and standards. The following projects were identified for this effort. Proposed reservoir sizes will be confirmed during pre-design. These projects are planned for the long term (past our planning period of 20 years) and no detailed costs were developed at this time. 9.4.8.1 Blackriver Reservoir – Valley 196 PZ This project acquires property and then plans, designs, constructs a new reservoir in the Valley 196 PZ to provide the City with additional storage along with operational flexibility, reliability, and redundancy of system capacity in case the City needs to take the existing North Talbot Reservoir out of service for maintenance. The new Blackriver Reservoir will supplement the storage that the North Talbot and Mt. Olivet Reservoirs provide to this operational area. The proposed reservoir size will be confirmed during the project’s pre-design. CHAPTER 09 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 9-19 In 2011, the City completed a site assessment and geotechnical investigations of a potential site in the Blackriver Quarry. A pre-design report was completed for a proposed 6.6-MG reservoir and related transmission main. 9.4.8.2 Replacement of Existing Mt. Olivet Reservoir and Pump Station – Valley 196 PZ This project plans, designs, and constructs the replacement of the existing 3-MG Mt. Olivet Reservoir and Pump Station, which were constructed in 1954. This reservoir provides storage to the Valley’s operational area and, once replaced, will supplement the storage that the North Talbot and future Blackriver Reservoirs provide to this operational area. In the past, the City recoated the existing tank’s interior and exterior and installed a cathodic protection system to extend its useful life. The City plans to replace the existing reservoir with a new 7-MG tank. In addition, the booster pump station will be replaced with two 150-hp and two 125-hp pumps, with a total capacity of 9,000-gpm. The reservoir size and pump sizes will be confirmed during the project’s pre-design. 9.5 CIP Program Detailed Summary The summary table in Section 9.1 summarizes the CIP projects and labels them as D, P, PZ, PS, ST, G, or R.

The following sections present the financial status of the City’s Water Utility, the funding required to finance the scheduled improvements, potential funding sources, and the impact that water system improvements will have on user rates. 10.2 Historical Financial Performance The City accounts for its water revenues and other funding sources in two main separate funds: Fund 405 (Operating Fund) and Fund 425 (Construction Fund). The Finance Department maintains the financial records for the Water Utility, and both the Finance Department and the Public Works Department monitor and evaluate the Water Utility’s fiscal performance. 10.2.1 Rates The City serves meter sizes ranging from 3/4 to 12 inches under the following customer classes: • Single family. • Multi-family. • Non-residential. • Private irrigation. • City irrigation. • Hydrant meter. The City offers reduced rates for water, wastewater, surface water, and garbage for low-income senior citizens (61 years of age and over), and low-income disabled citizens.

Other Revenues in Table 10.3 include debt proceeds, reimbursements, transfer-in funds from other departments, and other miscellaneous revenues. A total debt of $8 million was issued in CY 2016 and CY 2017, resulting in higher revenues. CHAPTER 10 | WATER MASTER PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 10-3 Over the last 3 years, the City’s water fund balance, which represents the total unexpended resources carried forward to future years, increased from $28.5 million to $38.0 million. CY 2019’s estimated ending balance of $7.2 million indicates that the City starts using the reserve to fund capital project expenditures in CY 2019.

Due to the debt proceeds, revenues were higher in CY 2016 and CY 2017 than those of later years. As illustrated in the figure, expenditures rose in CY 2019 because of increased capital spending, and not enough revenue is generated to fund upcoming capital project expenditures without a drawdown on reserves. CITY OF RENTON| WATER MASTER PLAN UPDATE | CHAPTER 10 10-4 | MAY 2021 | FINAL Figure 10.1 Historical Revenues vs Expenses 10.2.3 Outstanding Debt In the past, the City’s Water Utility funded a share of capital projects using debt and currently holds the following outstanding bonds: • 2012 Water/Sewer Refunding Revenue Bonds (2004): Principal and interest payments averaging approximately $265,000 per year from CY 2020 to CY 2022 and $853,000 per year from CY 2023 to CY 2027. • 2016 Water/Sewer Refunding Revenue Bonds (2008A): Principal and interest payments averaging approximately $502,000 per year, ending in 2027. • 2017 Water/Sewer Refunding Revenue Bonds (2007 & 2007 [02]): Principal and interest payments averaging approximately $693,000 per year, ending in 2022. The Water Utility’s debt-service coverage ratio (DSCR) is calculated by dividing the net income (revenues less expenses) by the annual debt-service payment. The City’s current bond documents require a DSCR of 1.25, meaning the City is required to have sufficient funds to meet all ongoing O&M expenses, as well as 1.25 times the total annual debt service payment. In practice, the City has maintained a coverage factor well above the requirement due to its relatively small amount of debt. 10.3 Methodology The financial sufficiency evaluation developed for this chapter aims to determine whether existing and adopted rates are sufficient to cover the capital program developed as a part of Master Plan and, if not, the level of rate increases that would be required to do so. The evaluation relies on a revenue requirements analysis, which is used to test revenue sufficiency against expected revenue needs. CHAPTER 10 | WATER MASTER PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 10-5 10.3.1 Financial Sufficiency Tests There are two tests used to define the annual revenues necessary to provide both sufficient (1) cash flow, and (2) debt coverage. These sufficiency tests are commonly used to determine the amount of annual revenue that must be generated from an agency’s rates: • Cash Flow Sufficiency Test defines the amount of annual revenue that a utility must generate in order to meet annual expenditure obligations. In the same lieu, the cash-flow test identifies projected cash requirements in each year. Cash requirements include operations and maintenance (O&M) expenses, debt-service payments, policy-driven additions to working capital, miscellaneous capital outlays, and rate-funded capital expenditures. These expenses are compared to the total annual projected revenues, and shortfalls are used to calculate the needed rate increases. In this analysis, the cash flow test is the driver of the rate increase. • Debt-Coverage Test refers to the collection of revenues to meet all operating expenses, debt service payments, and debt service obligations, such as DSCR. The debt-coverage test measures an agency’s ability to meet policy-driven revenue obligations. Currently, the City holds three outstanding debt obligations and does not have any plans to issue additional debt to fund capital projects in the near future. Typical DSCRs range from 1.10x to 1.35x depending on an agency’s financial situation and the type of debt being issued. For this analysis, the debt coverage test was set to meet a 1.25x DSCR based on the City’s outstanding bond’s requirements, meaning that the City must collect sufficient revenue through user rates to meet all on-going O&M expenses, as well as 1.25 times the total debt-service requirements due each year. The debt coverage test was sufficient in this analysis. 10.3.2 Assumptions and Inputs Financial projections in this analysis relied on the following assumptions and inputs: • Customer, demand, and revenue growth: Based on the Chapter 3, the demand is expected to increase 1.5 percent per year in average from CY 2020 to CY 2029. However, the City requested that revenue growth in the financial model be equal to the expected growth in retail customers, which is conservatively assumed as 0.5 percent per year. • Non-rate revenues: Given general inflation, interest and other revenue sources are anticipated to grow by 3 percent per year from CY 2020 to CY 2029. • O&M cost projection: O&M costs are expected to increase annually by 3 percent from CY 2020 to CY 2029 according to historical trends and projected benefit cost increases in the Seattle Consumer Price Index (CPI-U). • CIP costs: Capital improvement construction costs are escalated annually by 3 percent over the CIP’s 10-year period to account for inflationary increases in construction costs. • Debt-coverage ratio: The debt coverage test was set to meet a 1.25x coverage ratio per the City’s outstanding debt obligations. • Reserve target: Based on the City’s input, the target reserve’s ending balance is estimated at 90 days (24.7 percent) of annual O&M expenses. CY 2019’s ending fund balance of $7.2 million was used in the analysis. • Financing assumptions: The following assumptions were used for possible debt issuances: - Interest rate: 4 percent. CITY OF RENTON| WATER MASTER PLAN UPDATE | CHAPTER 10 10-6 | MAY 2021 | FINAL - Loan period: 20 years. - Issuance costs: 1 percent. • Existing debt: The City provided annual debt-service expenses for current outstanding revenue bond issues. 10.3.3 CIP Funding Strategy Scenarios Three funding strategy scenarios were developed to evaluate the 10-year CIP’s impact on the Water Utility’s financial status. Each scenario assumes a different amount of debt to fund the CIP projects. All scenarios include the expected debt issuance with the financing assumptions mentioned above: • Scenario 1, PAYGO (No Additional Debt): This scenario assumes that all 10-year CIP projects are funded by Pay-As-You-Go (PAYGO), using revenues from user rates and available reserves. The City has indicated that this is the preferred scenario as it hopes to no longer rely on debt as a means of controlling long-term expenses. • Scenario 2, Maximized Additional Debt: This scenario maximizes the use of debt to mitigate rate increases in the short term. The first additional debt issuance would be needed in CY 2022 with debt proceeds needed every 3 years of the analysis. • Scenario 3, Moderate Additional Debt: This scenario assumes that rate increases are front loaded in the first 5 years of the analysis, then additional debt issuances are used to smooth out peaks in CIP spending. The first additional debt issuance would be required in CY 2021 and another in CY 2025. The City has indicated that Scenarios 1 or 3 are the preferred scenarios as they would decrease reliance on debt. All three scenarios are detailed in Section 10.5. 10.4 Financial Projections Financial projections from CY 2020 through CY 2029 were developed using the assumptions and inputs described above, as well as other inputs provided by the City or developed for the project. All three scenarios used the same assumptions for O&M costs, capital expenditures, and most offsetting revenues (all except interest earnings). The financial forecast gives the City a snapshot of its current financial status. As numerous assumptions were made for analysis, projected results can vary from the actual data depending on factors such as actual customer use, demand projection, and growth. Therefore, this high-level projection should be updated and evaluated during future City budget development to confirm the assumptions and adjust as needed. 10.4.1 O&M Cost Projections Common to all scenarios, projected O&M costs are expenditures that the City incurs for day-to-day operations such as employee salaries and benefits, fuel, chemicals, and power. The City’s CY 2020 operating budget served as the basis for forecasting the future operating expenses for each utility. The budget was compared to actual financial information from the previous year to identify any anomalies or one-time expenditures that are not useful to the present projections. Table 10.5 presents the projected O&M costs for the 10-year analysis period. CHAPTER 10 | WATER MASTER PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 | 10-7 10.4.2 CIP Expenditures Table 10.6 presents the expenditures of short-term CIP projects identified in Chapter 9. All listed projects are “replacement and rehabilitation” related to existing infrastructure. This analysis organized projects based on priority and broke them down further into the following seven project types: • Distribution piping. • Pressure zone. • Annual repair and replacement programs. • Pump stations. • Storage. • General. • Regulatory. Each project total is spread out throughout the anticipated project years. Costs are escalated at 3 percent per year from CY 2020. Funding these CIPs is a primary driver for future rate increases and/or debt issuances. 10.4.3 Fund Balance and Reserves The City currently holds reserves that have been generated through user rates and other revenue sources. Based on the data provided by the City, money is held and tracked in the following separate funds: • Fund 405 (Operating Fund). This fund was created in 2006 to identify water utility revenues and expenses. Revenue sources for this fund are generally from water sales and collections but also include plan review and inspection fees, water meter installation fees, utility billing fees, rent and leases, and inter-fund reimbursements from other City’s departments for services provided. Expenses include O&M, debt service payments for Public Works Trust Fund (PWTF) loans, revenue bonds, taxes, and transfers to the Construction Fund. • Fund 425 (Construction Fund) is held for the design, construction, and project management of capital improvement projects. Revenues from this fund include transfers from the Operating Fund, special assessment fees, system development charges, water connection charges, City issued bonds, proceeds from revenue bonds, proceeds from PWTF loans, and from Community, trade, and economic development grants. The starting fund balance included in the analysis is based on each fund’s ending balance in CY 2019: $6 million in the Operating Fund and $1.2 million in the Construction Fund for a total of $7.2 million. Projected reserve balances for each funding strategy scenario vary year-to-year based on fluctuations in capital spending. The total target is typically made up of several components, which may include an operating reserve, capital reserves, rate stabilization reserves, debt service reserves. The City’s reserve target is 60 to 90 days.

O&M expenditures and revenues increase with the escalator factors discussed earlier. With no additional debt issuances, the current debt-service payments will end in CY 2027. If the CIP is implemented as scheduled without any debt issuances or rate increases, reserve levels would begin to drop in CY 2020 and be fully depleted by CY 2023, meaning the City will not be able to fund future capital investments. Figure 10.2 Ten-Year Financial Forecast Without Rate Increases or Additional Debt Issuances The following sections present the three funding scenarios, their results, and the necessary rate increases required to implement them. 10.5.2 Scenario 1- PAYGO (No Additional Debt) Scenario 1 assumes that all 10-year CIP projects are PAYGO-funded, and no additional debt would be issued. Figure 10.3 shows the cash funding required to pay a total of $76.9 million over the 10-year analysis period. Figure 10.4 presents the annual rate increases required to fully implement the CIP. The compounded rate increase over the 10-year projection period would be approximately 32.8 percent. CHAPTER 10 | WATER MASTER PLAN UPDATE | CITY OF RENTON DRAFT | MAY 2021 | 10-11 Figure 10.3 Scenario 1 (PAYGO) Capital Funding Sources Figure 10.4 Scenario 1 (PAYGO) Rate Increases Under Scenario 1, user rates would increase in the initial years to build the financial capacity necessary to fund CIP expenditures in peak years. Once that funding capacity begins to grow with the compounding effects of the rate increases, less severe increases could be implemented. Rate increases could also potentially be smoothed if the City elects to further decrease reserves in years with high levels of capital spending. CITY OF RENTON| WATER MASTER PLAN UPDATE | CHAPTER 10 10-12 | MAY 2021 | DRAFT Figure 10.5 summarizes 10-year financial projection under Scenario 1. With the rate increases noted in Figure 10.4, the City would have sufficient cash available every year to fund capital projects. Figure 10.5 Scenario 1 (PAYGO) Financial Projection If the City ultimately decides to adopt a cash-funding model such as Scenario 1, prudent financial planning will be imperative to ensure that sufficient revenues or reserves are available every year and to avoid delaying projects. Table 10.7 summarizes the revenue requirement, cash flow, and fund balances for the next 10 years if Scenario 1 is implemented.

After CY 2029, no further rate increases would likely be required to keep up with increases in O&M costs and continued capital investments. Figure 10.6 Scenario 1 (PAYGO) Estimated Single Family Residential (SFR) Monthly Bills 10.5.3 Scenario 2 – Maximum Additional Debt Scenario 2 assumes the maximized use of additional debt to fund CIP projects. The first additional debt issuance would need to take place in CY 2022, and debt proceeds for capital funding would be required in every 3 years thereafter. This heavy use of debt would allow the City to spread costs out over time to mitigate rate increases in the short term. Table 10.8 shows the projected required debt issuances, issuance costs associated with each issuance, and the estimated debt service payment. The Annual Debt Service in the table indicates average annual debt service payment during the analysis years (CY 2020 –2029). The actual debt service payment would vary each year.

CHAPTER 10 | WATER MASTER PLAN UPDATE | CITY OF RENTON DRAFT | MAY 2021 | 10-15 Figure 10.7 shows the expected capital funding sources for each year of the analysis under Scenario 2. Approximately, $53.4 million in cash funding and $23.5 million in new bond proceeds would be required to fund the $76.9 million CIP, as summarized in Table 10.9.

Under Scenario 2, rate increases could be held constant at 2 percent per year from CY 2021 to CY 2024, as shown in Figure 10.8. After CY 2024, higher increases at 3.2 percent per year would be required in order to meet debt coverage requirements. The compounded rate increase over the 10-year projection period would be approximately 26.7 percent. CITY OF RENTON| WATER MASTER PLAN UPDATE | CHAPTER 10 10-16 | MAY 2021 | DRAFT Figure 10.8 Scenario 2 (MAX DEBT) Rate Increases Figure 10.9 summarizes 10-year financial projection under Scenario 2. With the increases noted above, the City would have sufficient cash available every year to fund capital projects. The projected working capital balance would exhibit less year-to-year fluctuation as compared to Scenario 1 since the use of debt helps smooth the impact of peaks in CIP expenditures. At the end of the projection period, the City would have approximately $21.9 million in outstanding debt principal.

Figure 10.14 Scenario 3 (MODERATE DEBT) Estimated SFR Monthly Bills 10.6 Conclusion Figure 10.15 compares each scenario’s total capital funding sources from CY 2020 to CY 2029. As shown, Scenario 2 would require substantial use of debt to hold rate increases to 2 percent per year through CY 2025 and still implement the full 10-year CIP. Figure 10.15 Capital Funding Comparison Figure 10.16 compares the outstanding debt principal and projected interest payments that the water funds would hold after CY 2029 for each scenario. Under Scenario 2, the City would still need to pay off approximately $21.9 million in debt principal with almost $11 million in interest CHAPTER 10 | WATER MASTER PLAN UPDATE | CITY OF RENTON DRAFT | MAY 2021 | 10-23 payments. This will lead to higher long-term costs and rate increases beyond CY 2029 as compared to what’s demanded by the other scenarios. Furthermore, the City may not be able to issue debt at the frequency required for Scenario 2. Figure 10.16 Comparison of Outstanding Debt After CY 2029 Figure 10.17 compares estimated single family residential bills from CY 2020 to CY 2029 under each scenario. As shown, the long-term rate outlook for each scenario has the same general magnitude with estimated single family charges ranging from about $61 to $68 per month by CY 2029. Increasing the amount of debt issued allows rate increases to be smoothed over time for a more gradual ramp-up to the ultimate rates. Figure 10.17 Estimated SFR Bill Comparison The projections presented in this chapter are intended to guide the financial planning of the City’s Water Utility, not to serve as the basis for any implemented rate increases. The City will need to confirm the capital projects that could be included within future budget development. This will give the City the opportunity to develop a funding strategy using their rate model and proposed recommended rate modifications.

When using an alternative format, it must describe all of the elements; 1a), b), c), d), and e), when they apply. For water system plans (WSP), a consistency review is required for the service area and any additional areas where a municipal water supplier wants to expand its water right’s place of use. For small water system management programs, a consistency review is only required for areas where a municipal water supplier wants to expand its water right’s place-of-use. If no water right place-of-use expansion is requested, a consistency review is not required. For engineering documents, a consistency review is required for areas where a municipal water supplier wants to expand its water right’s place-of-use (water system plan amendment is required). For noncommunity water systems, a consistency review is required when requesting a place-of-use expansion. All engineering documents must be submitted with a service area map (WAC 246-290- 110(4)(b)(ii)). A) Documenting Consistency: The planning or engineering document must include the following when applicable. a) A copy of the adopted land use/zoning map corresponding to the service area. The uses provided in the WSP should be consistent with the adopted land use/zoning map. Include any other portions of comprehensive plans or development regulations that relate to water supply planning. b) A copy of the growth projections that correspond to the service area. If the local population growth projections are not used, explain in detail why the chosen projections more accurately describe the expected growth rate. Explain how it is consistent with the adopted land use. c) Include water service area policies and show that they are consistent with the utility service extension ordinances within the city or town boundaries. This applies to cities and towns only. d) All service area policies for how new water service will be provided to new customers. e) Other relevant elements the Department of Health determines are related to water supply planning. See Local Government Consistency – Other Relevant Elements, Policy B.07, September 2009. B) Documenting an Inconsistency: Please document the inconsistency, include the citation from the comprehensive plan or development regulation, and explain how to resolve the inconsistency. C) Documenting a Lack of Local Review for Consistency: Where the local government with jurisdiction did not provide a consistency review, document efforts made and the amount of time provided to the local government for review.

February 4, 2021 RE: Local Government Consistency Determination Form – City of Renton Planning Department a) The water system service area is consistent with the adopted land use and zoning within the service area. City of Renton Water Utility Engineering Response: Evaluating land use and zoning within the water service area is an important aspect of planning how the system will address future needs as land use patterns change. During this water system plan update, an existing land use map and a future land use map were prepared to guide water service and long-term planning for system improvements. However, the water service area’s land use maps, as shown in Figures 3.2 and 3.3, were prepared using a modified list of land use designations, different from the City’s adopted land use schema, shown on Figure 3.1. Renton’s adopted land use schema identifies six types of land uses: Residential Low Density, Residential Medium Density, Residential High Density, Commercial Mixed Use, Employment Area, and Commercial Office Residential (Ordinance #5915). Each of these land uses has designated zones that detail the types of land uses allowed in those zones. Overall, there are 19 zoning designations in the Land Use Plan. For water system planning purposes, the adopted land uses and zones were compiled into 11 land- use designations: single-family, multi-family, commercial, industrial, mixed use, vacant, agriculture, open space, park, public/quasi-public, and right-of-way. While land-use designations in this Water System Plan Update are a modified version of the adopted land use schema, the consolidated list maintains consistency with the foundation and rationale of the adopted land use and zoning. DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT 1 ENV ENVIRONMENTAL CHECKLIST Planning Division 1055 South Grady Way-Renton, WA 98057 Phone: 425-430-7200 | www.rentonwa.gov PURPOSE OF CHECKLIST: The State Environmental Policy Act (SEPA), Chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write “do not know“ or “does not apply“. Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. 2 USE OF CHECKLIST FOR NONPROJECT PROPOSALS: Complete this checklist for non-project proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For non-project actions (actions involving decisions on policies, plans and programs), the references in the checklist to the words “project," "applicant,“ and "property or site“ should be read as "proposal," "proposer,“ and "affected geographic area," respectively.

Proposed timing or schedule (including phasing, if applicable): The City of Renton 2019 Water System Plan Update (Plan) is scheduled for adoption in 2020. 7. Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? If yes, explain. No. This Plan lists capital improvement projects planned by the City within the next 10 years and long-term projects over the next 20 years. Proposed locations are shown in the Plan. 8. List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. Depending upon the scope of the projects proposed in the Plan, an individual environmental checklist and threshold determination would be completed as specified projects are proposed for construction. 9. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. At this time, there are no known pending applications for general applicability related to the area covered by the water system. There may be applications pending related to improvements to the water system such as various on-going plats and developer extensions occurring within the water service area. The City plans to adopt the capital improvement plan outlined in this document as part of the City’s 10-year capital improvements plan. 3 10. List any government approvals or permits that will be needed for your proposal, if known. The Plan must be approved by the City of Renton, King County, the Washington State Department of Health, and the Washington State Department of Ecology. 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. The City of Renton proposes the adoption of a new Water System Plan to supersede the existing Water System Plan adopted in 2012. This Plan is an updated version of the City’s 2012 Water System Plan. The purpose of this Plan is to document changes to the City’s water system, to identify required system modifications, and to appropriately outline capital improvement projects proposed to meet future water demands as well as system maintenance and improvement activities. Maintaining a current plan is required to meet regulations of the Washington State Department of Health and the requirements of the Washington State Growth Management Act. The Plan examines the existing water service area, which includes a majority, but not all, of the city limits. The water service area encompasses an area of approximately 17.25 square miles. The City of Renton has no plans to serve beyond the limits of the current water service area. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The policies and guidance of this Plan are applicable throughout the City of Renton’s water service area. The existing water service area includes a large portion, but not all, of the city limits. The water service area encompasses an area of approximately 17.25 square miles and is shown as the Retail Water Service Area on Figure 1.3. 4 B. ENVIRONMENTAL ELEMENTS 1. EARTH a. General description of the site (check or circle one): Flat, rolling, hilly, steep slopes, mountainous, other _____________. The water service area includes steep slopes, several hills, a plateau, and river valley areas. b. What is the steepest slope on the site (approximate percent slope)? The slopes vary from flat (zero percent) to very steep (over 40 percent). Steep slopes exist along the Maple Valley Highway to the north and south of the Cedar River Valley (southern edge of Renton Highlands; northern edge of Scenic Hill and Rolling Hills), along the eastern side of I-405 (eastern edge of the Renton Highlands), along the southern (SR 900) and eastern (Rainier Ave N) edges of Renton West Hill, along the western (SR 167) and northern (I-405) edges of Talbot Hill and the western edge (I-405) of Scenic Hill. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any agricultural land of long-term commercial significance and whether the proposal results in removing any of these soils. According to the USDA’s Web Soil Survey, the main soil types within the water service area include: Alderwood gravelly sandy loam, Alderwood and Kitsap soils, Arents-Alderwood material, and Indianola loamy sand. Alderwood gravelly sandy loam makes up over 30% of the water service area and is considered prime farmland. Using engineering classifications: there is a wide variety of highly variable glacial deposits in the water service area that include clay, silt, sand, gravel, cobbles, and boulders. In the river valley areas, there is a variety of modern alluvium and undifferentiated deltaic deposits. Adoption of the Water System Plan Update will not itself result in the removal of agricultural soil. Specific projects that are subject to environmental review will be evaluated for their impact to agricultural soils prior to implementation. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Within the City, there are areas of unstable soils including steep slopes and historic coal mines. Some alluvial deposits in the Cedar River Valley and old Black River Valley may be subject to liquefaction during seismic events. Sensitive areas are mapped by the City and are subject to regulation under Renton Municipal Code Title IV, Development Regulations. Specific projects that are subject to environmental review will be evaluated for their soil conditions prior to implementation. 5 e. Describe the purpose, type, total area, and approximate quantities and total affected area of any filling, excavation, and grading proposed. Indicate source of fill. N/A, non-project action. However, the water system construction projects identified in the Plan will require excavation and grading of an undetermined quantity of material. Specific projects will be subject to individual environmental review before implementation. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. N/A, non-project action. Adoption of the Water System Plan will not itself result in the clearing, construction, or use of soils, however, the Plan’s programs and projects may result in erosion from construction. Specific projects that are subject to environmental review will be evaluated for erosion potential prior to implementation. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? N/A, non-project action. Specific projects will be subject to individual environmental review before implementation. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: N/A, non-project action. Where applicable, best management practices, along with erosion and sedimentation control measures, will be used in all areas of potential erosion. Specific projects will be subject to individual environmental review before implementation. 2. AIR a. What types of emissions to the air would result from the proposal during construction, operation, and maintenance when the project is completed? If any, generally describe and give approximate quantities if known. N/A, non-project action. Adoption of the Water System Plan will not itself result in air emissions, however, the Plan’s programs and projects may be a source of emissions from construction activity and increased usage of generators during maintenance, testing, and power outages events. Specific projects that are subject to environmental review will be evaluated for air emissions potential prior to implementation. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. N/A, non-project action. Specific projects that are subject to environmental review will be evaluated for off-site sources of emissions prior to implementation. c. Proposed measures to reduce or control emissions or other impacts to air, if any: N/A, non-project action. However, standard emissions controls for construction equipment will be utilized during construction of projects recommended by this Plan. Specific projects that are subject to environmental review will be evaluated for their potential impact and corresponding mitigation measures prior to implementation. 6 3. WATER a. Surface Water: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. There are multiple surface water bodies within the water system area. The northwest boundary of the water service area is the shoreline of Lake Washington. The rivers and streams that run through the water service area include the Cedar River, Green River, May Creek, and Springbrook Creek. The Cedar River is tributary to Lake Washington and the Green River is a tributary to Puget Sound. May Creek flows into Lake Washington and Springbrook Creek flows into the Green River. All water bodies and wetland boundaries are cataloged in the City’s GIS (COR Maps). 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. N/A, non-project action. However, the Plan’s programs and projects may require work within 200 feet of surface water bodies. These projects will be subject to individual review and compliance with the City’s Shoreline Master Program. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. N/A, non-project action. Adoption of the Water System Plan Update will not itself result in the direct alteration of the environment, however, the Plan’s programs and projects may result in the addition or removal of fill and dredge material. The potential impacts of these actions are currently unknown. Projects that are subject to environmental review will be evaluated for potential impacts and corresponding mitigation measures prior to implementation. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. N/A, non-project action. Adoption of the Water System Plan Update will not itself result in the withdrawal or diversion of surface water. Projects that are subject to environmental review will be evaluated for potential impacts and corresponding mitigation measures prior to implementation. 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan: N/A, non-project action. However, some portions of the City are within or adjacent to 100-year floodplains. Projects that are subject to environmental review will identify floodplain boundaries prior to implementation. 7 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. N/A, non-project action. However, no waste material will be discharged into surface waters during construction of projects recommended by this Plan. Projects that are subject to environmental review will identify discharge plans prior to implementation. b. Ground Water: 1) Will groundwater be withdrawn from a well for drinking water or other purposes? If so, give a general description of the well, proposed uses and approximate quantities withdrawn from the well. Will water be discharged to groundwater? Give general description, purpose, and approximate quantities if known. N/A, non-project action. Adoption of the Water System Plan Update will not itself result in the withdrawal of groundwater. A description of the City’s groundwater wells and spring (infiltration gallery) is provided in the Plan and includes detailed information on source locations, water rights, and withdrawal quantities. The City’s current and future groundwater withdrawal is limited by the water rights that have been granted by the Washington State Department of Ecology. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. N/A, non-project action. However, no waste material will be discharged into the ground during projects recommended by this Plan. Projects that are subject to environmental review will identify discharge plans prior to implementation. c. Water runoff (including storm water): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. N/A, non-project action. Adoption of the Water System Plan Update will not itself result in runoff. Projects that are subject to environmental review will be evaluated for potential impacts and corresponding mitigation measures prior to implementation. 2) Could waste materials enter ground or surface waters? If so, generally describe. N/A, non-project action. Adoption of the Water System Plan Update will not itself result in waste materials entering ground or surface waters. Projects that are subject to environmental review will be evaluated for potential impacts and corresponding mitigation measures prior to implementation. 8 3) Proposed measures to reduce or control surface, ground, and runoff water, and drainage pattern impacts, if any: N/A, non-project action. Adoption of the Water System Plan Update will not itself result in any such impacts. Projects that are subject to environmental review will be evaluated for potential impacts and their corresponding reduction and control measures prior to implementation. 4. PLANTS a.

Proponent Signature: Name of Signee (printed): Position and Agency/Organization: Date Submitted: Water Utility Engineering Manager, City of Renton Abdoul Gafour Type text hereAPRIL 3, 2020 20 D. SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (IT IS NOT NECESSARY to use these sheets for project actions.) Because these questions are very general, it may be helpful to read them in conjunction with the list of the elements of the environment. When answering these questions, be aware of the extent the proposal or the types of activities likely to result from the proposal, would affect the item at a greater intensity or at a faster rate than if the proposal were not implemented. Respond briefly and in general terms 1. How would the proposal be likely to increase discharge to water; emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise? The Water System Plan will not itself increase discharge to water, emissions to air, hazardous substances, or production of noise, however, the Plan’s programs and projects have the potential for these effects. For example, projects recommended by the Plan that require construction may result in exhaust emissions, dust, and noise from construction equipment as well as temporary storage of hazardous materials. All hazardous materials storage within the Aquifer Protection Area will be required to comply with the Aquifer Protection Code in order to prevent contamination of the City’s main drinking water source. Specific projects that are subject to environmental review will be evaluated for potential impacts and corresponding mitigation measures prior to implementation. Proposed measures to avoid or reduce such increases are: For the Water System Plan adoption, there are no specific measures planned to reduce these impacts. Best management practices will be used to minimize impacts, in accordance with local, state, and federal laws, during the planning and construction of any applicable projects. Proposed projects will be reviewed and addressed on an individual basis by appropriate agencies prior to implementation. 2. How would the proposal be likely to affect plants, animals, fish, or marine life? Adoption of the Water System Plan will not itself result in direct effects to plants, animals, fish, or marine life. It is not anticipated that any of the proposed projects within the Plan will have an impact upon vegetation or wildlife, however, there is potential for impacts to occur during construction efforts. Specific projects that are subject to environmental review will be evaluated for potential impacts to vegetation and wildlife and corresponding mitigation measures prior to implementation. Proposed measures to protect or conserve plants, animals, fish, or marine life are: Specific projects that are subject to environmental review will be evaluated for their potential impact to plants, animals, fish, and marine life. Potential impacts will be reported with corresponding mitigation measures to protect or conserve vegetation and wildlife. Proposed projects and mitigation measures will be reviewed and addressed on an individual basis by appropriate agencies prior to implementation. 21 3. How would the proposal be likely to deplete energy or natural resources? Adoption of the Water System Plan will not itself result in the direct depletion of energy or natural resources. It is not anticipated that any of the proposed projects within the Plan will have a strong impact on energy or natural resources, however, some projects may require the use of energy resources. For example, the running or testing of water system facilities uses electricity and construction projects require fuel for equipment operation and delivery of materials. Specific projects that are subject to environmental review will be evaluated for potential impacts to energy resources and corresponding mitigation measures prior to implementation. Proposed measures to protect or conserve energy and natural resources are: For the Water System Plan adoption, best management practices will be used to minimize energy usage. For example, the water utility maximizes the potential for gravity flow in the water system whenever possible. Additionally, the Plan includes a water use efficiency program intended to provide water resource savings over time. Programs and projects proposed in the Water System Plan may also result in energy conservation features such as improvements to pump stations and strategies to increase system efficiency. Best management practices will be used in the design, construction and operations of the infrastructure proposed by the Plan, in accordance with local, state, and federal laws, during the planning and construction of any applicable projects. Proposed projects will be reviewed and addressed on an individual basis for energy and natural resources impacts by appropriate agencies prior to implementation. 4. How would the proposal be likely to use or affect environmentally sensitive areas or areas designated (or eligible or under study) for governmental protection; such as parks, wilderness, wild and scenic rivers, threatened or endangered species habitat, historic or cultural sites, wetlands, floodplains, or prime farmlands? Adoption of the Water System Plan will not itself result in direct effects to environmentally sensitive areas or areas designated for governmental protection, however, there is potential for the Plan’s programs and projects to occur in the immediate vicinity of sensitive areas. The potential impacts from these actions are currently unknown. Specific projects that are subject to environmental review will be evaluated for potential impacts and corresponding mitigation measures prior to implementation. Proposed measures to protect such resources or to avoid or reduce impacts are: Specific projects that are subject to environmental review will be evaluated by the appropriate agencies for their potential impact and corresponding mitigation measures prior to implementation. All such projects will be required to comply with applicable local, state, and federal guidelines and regulations regarding environmental protection. 22 5. How would the proposal be likely to affect land and shoreline use, including whether it would allow or encourage land or shoreline uses incompatible with existing plans? Adoption of the Water System Plan will not itself result in direct effects to land and shoreline use and will not allow or encourage land or shoreline uses incompatible with existing plans. Specific projects that are subject to environmental review will be evaluated for land and shoreline use prior to implementation. Proposed measures to avoid or reduce shoreline and land use impacts are: The Water System Plan is designed to support City land use plans, including adhering to the guidelines set by the state Growth Management Act. All such projects will be required to comply with applicable local, state, and federal guidelines and regulations regarding shoreline and land use. Proposed projects will be reviewed and addressed on an individual basis by appropriate agencies prior to implementation. 6. How would the proposal be likely to increase demands on transportation or public services and utilities? Adoption of the Water System Plan will not increase the demand for transportation, public services, or utilities. The Plan itself is partly in response to population growth and increased demands on the water utility. Water demand projections are included in Chapter 3 of the 2019 City of Renton Water System Plan Update. Proposed measures to reduce or respond to such demand(s) are: The proposed Water System Plan was developed, in part, as a response to increased demands on the City’s water utility system. 7. Identify, if possible, whether the proposal may conflict with local, state, or federal laws or requirements for the protection of the environment. The 2019 City of Renton Water System Plan Update does not conflict with any known local, state, or federal environmental laws or requirements. Specific projects that are subject to environmental review will be evaluated for adherence to environmental laws or requirements prior to implementation.

Consistent with the Memorandum of Understanding between the Department of Health (DOH) and Department of Ecology (Ecology), regarding joint review and approval of WSPs, this letter is being sent to your office with Ecology’s comments. Specific elements of the WSP review included the Water Rights Self-Assessment as well as additional water rights documentation, including Ecology’s water right files and previous City of Renton WSPs and project reports, as applicable. My review did not reveal any major issues of concern with the WSP and supplemental documentation. There are however a few lesser issues that should addressed. The terms used to identify the city’s water rights were not the same as those used in Ecology’s database, which made it difficult to access files for review. Since 1971 Ecology has referenced water rights using what are referred to as tracking numbers.

On September 16, 2020, the UTRC held an open public meeting and deliberated the plan content. The Committee agreed that the plan is thorough and very well prepared. The UTRC requests the following changes or clarifications before advancing the plan to the King County Council for approval: • We request city limits to be shown on all maps, to better identify which areas are subject to City jurisdiction, and which are unincorporated county. • Figure ES.1 and 1.3 – Service Area Map – The service area and future service area are shown as overlapping in the southern portion of Skyway-West Hill. Please clarify. • Figure ES.1 and 1.3 – Service Area Map – Areas depicted as “Urban Growth Boundary” should be correctly labeled as “Potential Annexation Areas” or “Unincorporated County.” • Figure ES.2 and 2.1 – Water Facility Locations – There is no pressure zone in the northeast corner, nor infrastructure in much of the western portion of the Earlington 370 pressure zone. • Figures 3.1 and 3.2 – Maps should show zoning and land use of future service areas as well as the current service areas. • Figure 3.2 – Future Land Use Based on Zoning – The map is correct in showing the areas in UKC in the southern end of SWH as SF land use, but many of them can be redeveloped to yield 3-4 units. • Figure 3.8 – Historical Consumption Trends by Customer Category – The bottom grouping shows two customers decreasing by nearly 5% and one increasing by 8% but it is unclear which number goes with which customer, and the 8% number seems like a very large change compared to what the lines are showing. • Table 3.9 – What explains the significant drop in connections from 2009-2010? • Table 3.11 – Portions of the Earlington 370 zone (and adjacent West Hill zone) are currently large- lot single-family zoning or multi-family that may redevelop and quadruple the number of units. Would such growth be supported with minimal impacts to planning forecasts? • Question: Does the City have a program of providing reduced rates for seniors or low-income property owners or renters? • Question: Skyway Water and Sewer is capped at 300,000 gallons. Is there an overage charge to Skyway if they exceed? • Table 3.17 ERU Projections –Why does the medium demand scenarios exceed the high demand scenario? City of Renton Water System Plan – Initial Review Prepared by J. Hill | 9/16/2020 2 • 5.3.1.6 Urban Growth Area – The Urban Growth Area is different from the Potential Annexation Areas. PAAs may be annexed to the City, while the Urban Growth Area is a regional boundary. Please use PAAs instead. • 5.3.1.16 Water Service to Properties in King County – Please clarify this section. We’re unclear by what a “developed area within unincorporated King County that is within the City’s RSA. However, there are three additional areas outside of the RSA served by Renton Water…” • 5.3.1.2 – Service Availability – Is there a definition or decision criteria of “timely and reasonable” used by Renton? • 7.3.3.3 – West Hill 495 Storage Recommendation – Is the only solution to reduce the operating band? Is this suitable for future growth in the associated pressure zones? • 9.4.7.2 – Water Conservation Program Implementation – Given the large non-English-speaking population in the area, are there such materials available in additional languages or simplified English? • Its unclear, given the resolution of maps such as 9.4 (CIP Specific Project Priority) where the current service boundaries and infrastructure are in relationship to properties on S 134th St between S Langston Rd and SW Sunset Blvd. Given King County’s ongoing Skyway-West Hill Subarea Planning process, we request a specific map for this area to aid in discussions about land use planning in the area. The UTRC thanks you for the opportunity to review and comment. We look forward to seeing a completed plan.

From:Steve Osguthorpe To:Katie Nolan Cc:Jeff Brauns; Patrick Subject:RE: City of Renton 2019 Water System Plan Update - Transmittal of Agency Review Draft Date:Saturday, June 27, 2020 7:05:57 AM Dear Ms. Nolan: Thank you for providing notice of Renton’s water system plan. It does not appear that the plan overlaps into the City of Newcastle jurisdictional boundaries (Newcastle’s water is provided by Coal Creek Utility District). I am therefore not sure if the Local Government Consistency Determination Form you are asking me to complete and return to you is relevant to Newcastle. Unless I hear otherwise from you, I will assume that it is not relevant and will not be returning the form. If there are specific issues you would like us to review or respond to, please let me know and I’ll try to coordinate the response you need. Again, thank you for keeping us informed. It is very much appreciated. Steve Osguthorpe, AICP Community Development Director (425) 649.4143 Ext. 112 City of Newcastle | 12835 Newcastle Way, Suite 200, Newcastle, WA 98056-1316 From: Katie Nolan [mailto:KNolan@Rentonwa.gov] Sent: Friday, June 26, 2020 6:56 PM To: Steve Osguthorpe <SteveO@newcastlewa.gov> Subject: City of Renton 2019 Water System Plan Update - Transmittal of Agency Review Draft Hi Mr. Osguthorpe, The City of Renton’s 2019 Water System Plan Update is available for review and comment. This Water System Plan has been transmitted to the Washington State Department of Health, King County, and adjacent water systems for their review in accordance with WAC 246-290. Given the 2019 Novel Coronavirus situation, we are providing an electronic pdf version, which can be downloaded from our website at COR Water Utility Engineering. If you have any comments after your review of the draft Water System Plan, please provide them to me in writing no later than August 31, 2020. Upon receipt of comments from DOH, the City will promptly revise the plan as necessary and resubmit it to DOH for final approval. Comments received after August 31, 2020 may not be addressed in the final version. Additionally, as you may know, we are required to obtain a consistency review for our water service area from local governments with jurisdiction. I have attached the Local Government Consistency Determination Form and we ask that you please return the completed form, which will be included in the final approved plan. If you have any questions, please contact me by email knolan@rentonwa.gov. I will be teleworking throughout the review period and have limited access to my work phone.

UTRCWhy does the medium demand scenarios exceed the high demand scenario?The ERU calculation appears to be affected by the Skyway Wholesale Large Consumer in the WH495 PZ. There is a cap of 300,000 gpd, which is reached in earlier planning years for the medium and high scenarios. Because the ERU projection calculation is dividing the ADD proj by the ADD ERU Value for large consumers (153 for medium and 160 for high), the medium scenario ERU is higher than the high scenario ERU when the ADD proj reaches 300,000 gpd.

A monthly meter charge shall be paid by SEATTLE in accordance with the meter charges as stated in RENTON's City Code at the time the meter is in service. 6) Priority and Continuity of Service. The determination of whether water is available for SEATTLE shall be at the sole discretion of RENTON. In the event of a condition requiring restrictions on the delivery of water, RENTON shall have the right to restrict or interrupt service to SEATTLE. RENTON may voluntarily interrupt or reduce deliveries of water to SEATTLE if RENTON determines that such interruption or reduction is necessary or reasonable. Except in cases of emergency and in order that SEATTLE's operations will not be unreasonably interfered with, RENTON shall give SEATTLE reasonable notice of any such interruption or reduction, the reason therefor, and the probable duration thereof. SEATTLE shall discontinue or reduce service from RENTON upon reasonable notice to RENTON. Service shall be reactivated or increased again subject to the aforementioned conditions. 7) Water Quality. The quality of water delivered under this AGREEMENT shall comply with all applicable provisions of State and Federal law and rules and regulations of the appropriate State agency governing water quality. In addition to the above requirements, RENTON agrees to deliver water which shall be of no less quality than is delivered to its customers throughout the RENTON service area.

It is recognized that runoff into SEATTLE's surface water storage facilities generally exceeds the storage capacity during the winter and spring months. It may be necessary, due to RENTON supplying water to SEATTLE, to allow RENTON's aquifer to recharge during the winter and spring months. Following a water shortage emergency and recovery of SEATTLE's water system impoundments on the Cedar and Tolt Rivers, SEATTLE will sell water to Renton. The water sale will be based on availability at the intertie locations between SEATTLE and RENTON's systems and at such flow rate as is available from the intertie location during the following winter or spring. The quantity of SEATTLE's water, made available for allowing RENTON's Aquifer to recharge, shall not exceed the quantity of water that was supplied by RENTON to SEATTLE during the water shortage emergency. SEATTLE will sell the water to RENTON at $0.77 per 100 cubic-feet which is SEATTLE's non-peak, old water rate charged by SEATTLE to its purveyors in 2002. This rate shall be revised each year during the term of the agreement. This flow rate, quantity and price is an integral part of this AGREEMENT and should not be considered as a precedent in possible future water sales to RENTON or to other existing or future wholesale customers. The determination of whether water is available for RENTON, to allow RENTON's Aquifer to recharge, shall be at the sole discretion of SEATTLE. SEATTLE may voluntarily interrupt or reduce delivery of said water, providing that such interruption or reduction is necessary or reasonable. Except in cases of emergency, and in order that Renton's operations will not be unreasonably interfered with, SEATTLE shall give RENTON reasonable notice of such interruptions or reduction, the reason therefor, and the probable duration thereof. 12) Payment. The party supplying water shall read the meter once each month at approximately thirty (30) day intervals. Payment shall be made by the party receiving water as soon as possible after receipt of statement from the party supplying water, and in any event, not later than the tenth (10) of the second month following the presentation of the bill. In the event a meter shall fail to register or obviously register incorrectly, the amount of water considered delivered through said meter shall be the amount delivered the previous day or the last day that the meter was previously known to be properly functioning and the total amount registered shall be pro-rated based on the number of days multiplied times the reading used. 13) Penalties For Late Payment. The party supplying water may assess a late charge on the party receiving water for failure to comply with the provisions in Section (12). This charge shall be at the rate of twelve percent (12%) per year. In the event that the party receiving water should fail to make any payment for a period of sixty (60) days after the same becomes due, the party supplying water shall have the right to terminate further water service until such delinquency is cured. 14) Procedure for Amending the Contract. Either party can request the other to consider an amendment of the AGREEMENT. Any proposed amendments shall be made in writing. Amendments may be made if they are mutually acceptable to RENTON and SEATTLE and signed by both parties. CAG-02-123 Agreement for the Sale of *ter in an Emergency by the City of Ren0to the City of Seattle Page 5 of 5 15) Access to Facilities and Records. Each party shall be entitled to inspect the facilities of the other at any reasonable time. Both parties agree to make mutually available such information or records as are at their disposal and as may be reasonably necessary to properly implement any section of this AGREEMENT. 16) Non-Assignability. Neither this AGREEMENT nor any interest therein shall be transferred or assigned by SEATTLE without prior written consent of RENTON. 17) Termination. This AGREEMENT may be terminated in whole or in part by either party any time after one year from the date of this AGREEMENT, upon ten (10) days written notice sent by certified mail to the other party.

RENTON shall provide ultimate service for the area north and west of the line shown. THE DISTRICT shall provide ultimate service for the area south and east of the line shown. 11 . Maintenance of Existing Facilities. THE DISTRICT and RENTON will each provide maintenance for its own facilities. If there are any serious problems due to a discharge which can be identified, and for which the source can be identified, the individual or company responsible will be held liable for damage. If a lack of maintenance, or if the type of maintenance by either RENTON or THE DISTRICT is identified as the source of said problem, then the party creating, or allowing, the situation shall be responsible and shall pay the costs of repair. In case of dispute over the source or responsibility of said problems, the Municipality of Metropolitan Seattle (Metro) shall serve as arbitrator in identifying and quantifying said problems provided that said arbitration and/or any reports generated by an investigation by Metro, shall be binding upon both parties in resolution of the dispute. 12. Allowable Capacities in the Lines being Transferred, and at Points Further Downstream. There are no restrictions on the capacity of the sewers from Ponderosa Estates as long as they are consistent with the current use of the properties. There are currently 35 single family residences, and the property is fully developed. If this condition ever changes, a further review of the capacity of the system shall be performed, and an additional agreement shall be developed between the parties. Capacity for the system in the Springbrook drainage basin shall be as follows: AT TIMES OF SIMULTANEOUS PEAK FLOW SOOS CITY OF RESERVED CREEK RENTON FOR CITY OF gpm) gpm) KENT (gpm) S. 192nd Street, at and below 1500 600 0 M H 34-3 4-7.04W400g.001 Page 8 of 11 S. 192nd Street, at and below 1800 1500 0 MH 34-OA S. 192nd Street, at and below 3900 1500 0 MH 80-14 West of MH 80-14 3900 1500 400 No connections, by either party, will be allowed between Manhole 34-OA and Manhole 80-15 except by mutual agreement. Both parties agree that either may exceed this amount at the non- peak times, as long as there are no negative impacts, and the combined capacity of the system is not exceeded, and prior notification is given to the other party. It shall be the responsibility of each part to monitor its flow as and when necessary to determine what the flow rate characteristics of the system are. If the combined capacity of the system is exceeded, the party exceeding its allowable rate shall have the option of making revisions within its own system to bring its flows into compliance with this Section, or of paying for improve- ments to either system which will increase the available capacity of the systems. If both parties exceed their allowable rate, the cost of any new facilities will be divided based upon the ratio of the percentage by which each party is exceeding its allowable rate. If the allowable rate is exceeded at only one location, the ratio at that location will be used. If the rate is exceeded at more than one location, the ratio will be based upon the furthest east point at which the allowable rates are being exceeded. If a regular surcharge condition exists that is not due to a blockage problem, a previously agreed upon temporary situation such as re-routing for construction, or by either party exceeding its capacity, the DISTRICT shall have the option of making revision within its own system to bring its flows into compliance with this section, or of paying for improvements to either system which will resolve the surcharge condition. Both parties acknowledge and agree that the City of Kent is not a party to this agreement, and the amount referenced for the City of Kent is for reference only and could be the basis for a separate agreement in the future involving THE DISTRICT and the City of Kent, and involving RENTON if their rate allowance is at all to be affected. 13. Connection of THE DISTRICT to RENTON Facilities. or RENTON to THE DISTRICT Facilities. Connection of facilities of either RENTON or THE DISTRICT to facilities of the other, or to facilities tributary to facilities of the other, shall be coordinated by both parties to assure: a) Payment of appropriate charges, b) up-to-date accounting of connections, c) potential sources of debris, or construction damage, are identified, and 4-7:04W4Wg.001 Page 9 of 11 d) inspection of connection construction can be scheduled. RENTON and THE DISTRICT shall each be responsible for maintenance of their own facilities, except as described in Section 11 above. Should damage of the facilities of one be traceable to a source within the jurisdiction of the other, RENTON and THE DISTRICT agree to assist each other in whatever action is necessary to identify, prosecute, fine, collect from, or otherwise deal with the responsible party. 14. Future Annexations to RENTON. The service areas listed in sections 1-7 of this AGREEMENT are the only areas of cross-service agreed to at this time. RENTON shall serve all other areas within RENTON without challenge by THE DISTRICT, based upon the City limits at the date of the agreement. THE DISTRICT shall serve all areas within THE DISTRICT's limits at the time of this agreement, except as previously detailed. Future annexation to RENTON shall not limit THE DISTRICT providing water or sewer service to those areas within THE DISTRICT limits to the standards of THE DISTRICT, even if there is conflict with RENTON standards, unless this is altered by future agreements. Future agreements may occur between RENTON and THE DISTRICT transfer- ring additional, or future, services areas and/or facilities by mutual agreement. 15. DISTRICT Comprehensive Water and Sewer Planning. THE DISTRICT will submit the current and all future Comprehensive Water and/or Sewerage Plans and amendments thereto involving area and/or improvements within RENTON City Limits. The Comprehensive Water and/or Sewerage Plans and amend- ments shall be in compliance with RENTON requirements for service within RENTON, except where existing facilities may differ from RENTON require- ments. No replacement or augmenting of the system shall be required at this time. As new facilities are planned and constructed within RENTON, they shall comply with RENTON technical standards then in effect. 16. Extensions of Utilities Across Properties. RENTON and THE DISTRICT agree that they will require property owners who m ust extend facilities to serve their property to extend said facilities to the far side of the property to provide a connection point for the future (or existing) facilities of the next property. 17. Recording of Agreement with King County. THE DISTRICT is hereby authorized to record a copy of a resolution in which a copy of this Agreement is incorporated with the office of the Auditor of King County, Washington, for the purposes of giving notice to all present and future owners of the real property described in Exhibit "E" that their properties are subject to the connection charges specified herein. 4-7:04ON00g.001 Page 10 of 11 18.

Sanctity of Agreement. This agreement constitutes the entire agreement of the parties, and there are no representations or oral agreements other than those listed herein, which vary the terms of this agreement. Future agreements may occur between the parties to transfer additional, or future, service areas and/or facilities by mutual agreement. 20. Obligations Intact.

"Joint Facilities Bonds" shall mean water and sewer revenue bonds issued by the City to pay Joint Facilities Costs of the Joint Facilities or future joint facilities and any future bonds hereafter issued and sold to refund such bonds if such refunding of bonds effects a savings to the City. If only a portion of the proceeds of any issue or series of bonds is devoted to Joint Facilities Costs or to the refunding of Joint Facilities Bonds, the percentage that such portion represents of the entire proceeds shall be applied to each maturity of such bonds and the amount of each redemption of such bonds, and such amounts equal to that percentage shall be Joint Facilities Bonds. g. "Joint Facilities Debt Service Expense" for Joint Facilities shall be as described in Exhibit C, Table 4. For future Joint Facilities, Joint Facilities Debt Service Expense shall include costs of issuance, interest and principal, on the Joint Facilities Bonds as defined above. 3. Construction of the Original Joint Facilities. The City has constructed the Joint Facilities and has advanced all Joint Facilities Costs therefor through the sale of Joint Facilities Bonds. The Joint Facilities constructed shall be owned by the City. 4. Maintenance and Operation of Joint Facilities. The City shall supply the District through the Joint Facilities, and the District shall be entitled and have the enforceable right to receive therefrom, water service in (but not exceeding) the quantities specified in Exhibit B, attached hereto and made a part hereof, subject to (a) the design and actual physical capacity of the Joint Facilities to furnish that water at any one time, (b) act of God, force majeure, or other cause beyond the reasonable control of the City, (c) change in quantities specified in Exhibit B made pursuant to Paragraph 6, and (d) restrictions due to emergency and/or drought, but only to the extent that a percentage reduction in supply rate is uniformly applied to the City and the District. Programmatic water conservation shall be encouraged, but is not the subject of this agreement. The City shall maintain and operate the Joint Facilities in accordance with prevailing engineering standards and in conformity with the then current standards and requirements established by applicable State and Federal law and agencies having jurisdiction over such maintenance and operation. The City shall carry public liability insurance for the Joint Facilities with limits in accordance with standard practice or shall establish and maintain a self-insurance program for the Joint Facilities.

No direct cost of claims F:IDMS\RPK\0030663.01 -2 - or other related Joint Facilities shall be allocated or charged to the District. Pursuant to reasonable notice to the City, the District shall have the right to observe the operation and maintenance of the Joint Facilities at any time. 5. Access to Joint Facilities. Upon reasonable notice to the City, the District shall have access to the Joint Facilities for observation purposes only, unless agreed otherwise in advance by the parties. 6. Future Joint Facilities. Future joint facilities to be constructed shall be agreed upon by the District and the City, but in no event shall be of less capacity and quality than is required by applicable Federal, State, or County laws and regulations. The District and the City shall confer and agree upon a method for financing such facilities. The payment of the cost of such future joint facilities shall be made in accordance with Paragraph 7. If regulatory agencies with jurisdiction over the Joint Facilities validly direct the upgrading of the Joint Facilities by the making of qualitative improvements to such facilities, the City shall immediately commence the planning, design, and construction of the improvements subject to the approval of the City Council and availability of sufficient funds to finance such improvements. 7. Financing Construction and Maintenance of Joint Facilities. In consideration for the City's acquiring, constructing, installing, maintaining, and operating the Joint Facilities, and as a condition for use thereof and service therefrom, the District shall pay to the City the amounts provided for in Paragraph 8. All such payments shall be made at the times and in the manner specified in Paragraph 8. To finance any future joint facilities costs, the City may issue water and sewer revenue bonds (Joint Facilities Bonds) which may have a lien position on the gross revenue of the City's waterworks utility, including the system of sewerage as a part thereof, on a parity with its outstanding water and sewer revenue bonds and any bonds hereafter issued on a parity of lien with those revenue bonds. Such Joint Facilities Bonds may be issued and sold at any time after the effective date of this Contract. If there are any excess proceeds from Joint Facilities Bonds and earnings from the investment thereof after payment of all costs relating to the purposes of such Bonds, the City shall deposit such excess proceeds and earnings into the Bond Redemption Fund for such bonds for the purpose of paying principal and interest as they come due or redeem such Bonds prior to their maturity, at such time such Bonds are subject to prior redemption. The charges for the District's share of the Joint Facilities Costs and the City's Maintenance and Operation Expenses shall be deemed water service charges. F:\DMS\RPK\0030663.01 -3 - 8. Billings and Payments. The District's billings for Joint Facilities shall be determined as follows: a. The District's total share of the Joint Facilities Debt Service Expense for Joint Facilities shall be as shown on Exhibit C, Table 4. The parties have agreed to remove Well No. 9 pump from the calculations. Exhibit C, Table 4 takes into account the sum of $117,075.88 on unpaid interest and debt service through December 31, 1992. The derivation of the figure on unpaid interest and debt service is set forth in Table 3B of Exhibit C. The annual debt service also includes the District's share equal to $15,000.00, for a one time telemetry expense, which item is to be installed on or about the date of signing of this agreement. This $15,000.00 shall not be adjusted. b. The District's share of future joint facilities and manner of payment therefor shall be agreed upon at the time of construction of such facilities. c. The District's share of the City's Maintenance and Operation Expenses for the water supply which supplies water to the Joint Facilities shall be computed annually by dividing the entire City's maintenance and operations cost for production and transmission only by the volume of water sold and then multiplying by the volume of water supplied to the District. The method used to determine the District's share is shown on Exhibit E, attached hereto and made a part hereof. Well No. 9 shall be included in the City's maintenance and operation cost for production and transmission and not in the Joint Facilities Debt Service Expense. City utility taxes and state excise taxes shall not be added to the payment to be made by the District to the City unless and until there is a future change in the law which would permit or require such taxation. d. The City shall bill the District once a year for the annual payments of the Joint Facilities Debt Service Expense. The City shall bill the District for the District's share of the City's Maintenance and Operation Expenses in monthly installments based on volume of water used. The District shall pay any billing within 60 days of receipt. Charges omitted in one month may be billed in the following month. Delinquent charges shall accrue interest on the unpaid balance at the rate of 12 percent per annum from date of delinquency until paid. By October 1 of each year, the City shall notify the District of the proposed budget for the Joint Facilities showing the estimate of the City's Maintenance and Operation Expenses for the ensuing calendar year. The budget amounts will be for informational purposes only to provide advance notice of anticipated changes, if any. The budget shall show an estimated cost per unit of volume, to be applied in determining monthly payments in Subsection d above. F:\DMS\RPK\0030663.01 -4 - By March 1 (or as soon as practical thereafter) of each year following the year for which the budget estimates apply, the City shall determine and notify the District of the actual City's Maintenance and Operation Expenses, and the actual water consumption by the District and the City for the immediately preceding calendar year or part thereof covered by this contract. If the actual requirements and expenses exceed the total payments made by the District, the District within 30 days after such notification shall pay to the City its share of that deficit. If the actual requirements and expenses for the District were less than the total payments made by the District for that preceding calendar year, the City shall retain those excess payments and credit the excess payments against the next payments due from the District. During any year, the City shall operate within the Joint Facilities budget. Should the City's Maintenance and Operation Expenses increase above budget estimates, the City may amend the budget and increase the charges to the District after notifying the District at least 90 days before the increase shall take effect. Such notification shall state the reasons for such increase. 9. Covenants to Make Payments. The District irrevocably covenants, obligates, and binds itself to pay to the City the applicable payments and charges referred to in Paragraph 8 as water service charges out of the gross water revenues, and/or water and sewer revenues of the District or from such other money legally available to the District for such purpose as determined by the District. The water service charges shall, subject to the qualification below, be treated as maintenance and operation expenses and shall expressly be made a part of the maintenance and operation expenses of the District's system in any future bond issue or other financing payable in whole or in part from the revenues of the system. Further, the water service charges shall be payable and constitute a charge prior and superior to any charge or lien of any revenue bonds issued by the District payable from the gross revenues of the system, unless such future bond issue or other financing shall be on a parity of lien on such revenues with presently outstanding revenue bonds and such outstanding bonds do not permit such priority of payment. It is recognized the District may have outstanding revenue bonds payable in whole or in part from the gross revenues of the system. Nothing in this paragraph is intended to violate, nor shall it be construed to violate, any covenants respecting those outstanding bonds, and such covenants, to the extent there is a conflict between them and this section, shall control with respect to such outstanding bonds and bonds issued on a parity therewith. The District irrevocably covenants and agrees to establish rates and collect fees for water service, which will be sufficient to pay the water service charges to the City and to meet the covenants of existing bond issues which constitute a charge upon the gross revenues of the system. The City agrees to establish rates and collect fees for water service which will be at least sufficient to pay the expenses of maintenance and operation of the water utility of the City and meet the principal, interest, and coverage requirements of any and all revenue bonds of the City which constitute a charge upon the gross revenue of such water utility. F:\DMS\RPK\0030663.01 -5 - 10. Furnishing of Books and Records. The District and the City will make available at reasonable times for inspection and copying their books and records relating to this contract and their respective system and utility. At a reasonable time prior to the sale of any Joint Facilities Bonds, the District and the City shall furnish to each other all public information which the City or the District may require having a bearing on the issuance and sale of such bonds. 11. Covenant Against Assignment. Conveyance, Merger. The District shall not assign obligations under this contract or assign or convey local facilities to any person or entity without first receiving the written consent for such action from the City Council. The City shall not assign its obligations under this contract or convey the Joint Facilities to any person or entity without first receiving the written consent for such action from the District Board of Commissioners. The District shall not permit the merger of it or its local facilities into another municipal corporation without the written consent of the City Council, unless the entity resulting from the merger shall assume and agree to perform all obligations of the merging entities under this contract. 12. Holders of Joint Facilities Bonds. The obligations of the District under this contract shall run to the benefit of the holders of the Joint Facilities Bonds and bonds issued on a parity therewith. 13. Effective Date -Term of Contract -Use of Joint Facilities. The effective date of this contract shall be January 1, 1993. This contract shall be effective until terminated by agreement of the parties; provided, that the parties shall not terminate the agreement until December 31, 2012, or such longer period as any Joint Facilities Bonds are outstanding or the payment thereof is not fully provided for, secured, and funded. The District shall have the right to use the Joint Facilities until this contract is terminated by agreement of the parties. 14. Participation by Others. Provision is hereby made for providing service to a third party or parties by the use of the Joint Facilities or supply from the City's or the District's system from the Joint Facilities. Such provision would be based upon: 1) a sufficient amount of unused capacity of the Joint Facilities to provide the service requested, 2) payment amounts that provide compensation to the City and the District that is adequate as determined mutually by the City and District, and 3) a mutually agreed upon distribution of such compensation between the City and the District. 15. Resolution of All Claims. This contract is a resolution of all claims by both parties as of the date of signing of this contract. Both the District and the City release all current or future claims related to past charges, methods of charging, and other monetary and equitable claims that could be raised. The District and the City release these claims on the basis of the accounting information provided in Exhibit C. The District and City agree that the calculations contained in Exhibit C and the methodology used at arriving at those calculations F:\DMS\RPK\0030663.01 - 6 - The Joint Facilities consist of the following components: 1. The West Hill Supply Booster Pump Station which pumps water from the City's 196 pressure zone to the West Hill Reservoir. 2.

Maintenance of Existing Facilities: CRWSD and RENTON will each maintain their own facilities, according to industry standards. 4. DISTRICT Comprehensive Water and Sewer Planning. CRWSD will submit, to RENTON, all future Comprehensive Water and Sewerage Plans and amendments thereto involving area and/or improvements within RENTON City Limits. Said submission of the CRWSD Plan(s) is to assure consistency with adopted city plans, policies, and land use controls, assist in the review of new development proposals and right-of-way construction permits, and to fulfill the responsibilities set forth in RCW 57 and King County Title 13. As new facilities are planned, constructed, maintained, and/or replaced within RENTON, they shall comply with RENTON design and construction standards then in effect, or CRWSD design and construction standards, whichever are the higher design and construction standards. 5.

Franchise Agreement. Upon RENTON annexing property within the CRWSD service area, RENTON shall grant CRWSD, for the purposes of continuing use of rights-of-way, a temporary franchise for utility facilities within the annexed territory. This franchise shall have the same provisions as stated in the franchise between King County and CRWSD and have a term not to exceed 3 (three) years. RENTON and CRWSD will immediately begin negotiations for a new franchise for the purposes of rights-of-way use for CRWSD service area within RENTON. The new franchise shall be negotiated within three years. Upon any subsequent annexations by RENTON within the CRWSD service area, RENTON shall amend the franchise to include the annexed area, in order to maintain one franchise agreement. The franchise shall maintain the remaining balance of the term of the franchise. The franchise should include any updated provisions as approved by RENTON and agreed to by CRWSD. Any franchise agreement issued hereunder shall be consistent with the respective comprehensive plans of the parties and State law. 7. Governmental Approvals. The parties will give notice of the adoption of this Agreement to Metropolitan King County, to the Department of Ecology, to the Department of Health, and to any other agency with jurisdiction, and shall cooperate and assist in any reasonable manner in procuring any necessary approvals hereof by those agencies. 8.

Summary of Action: The City and Cedar River Water and Sewer District (CRWSD) have negotiated an interlocal agreement describing our mutual water and sewer boundaries. STAFF RECOMMENDATION: The Planning/Building/Public Works Department recommends that Council approve the interlocal agreement between the City and CRWSD describing our mutual sewer and water service boundaries and authorize the Mayor and City Clerk to execute the interlocal agreement. CRWSD AB.DOC/ CITY OF RENTON PLANNING/BUILDING/PUBLIC WORKS MEMORANDUM DATE: January 20, 1999 TO: Dan Clawson, Chair Members of the Utilities Committee VIA:Mayor Jesse Tanner FROM: Gregg Zimmerman, Administrator 6- Planning/Building/Public Works Department STAFF CONTACTS: David Christensen(x-7212) Abdoul Gafour (x-7210) SUBJECT: Water and Sewer Boundary Agreement Between Renton and Cedar River Water and Sewer District ISSUE: The City has been negotiating an interlocal agreement with Cedar River Water and Sewer District CRWSD). This agreement describes the mutual boundaries between our water and sewer service areas and lays a foundation for future negotiations of a franchise agreement when properties served by CRWSD are annexed to the City. We have completed these negotiations and are asking for Council's approval of the agreement and adoption of a resolution authorizing the Mayor to execute the agreement. RECOMMENDATION: Staff recommends that Council approve the agreement and that Council authorize the Mayor and City Clerk to execute the interlocal agreement. BACKGROUND.SUMMARY: The City of Renton and CRWSD do not currently have either a water or sewer boundary agreement. CRWSD initiated negotiation of this interlocal agreement when, as part of the review of the CRWSD water plan, the Department of Health (DOH) commented on the need for adjacent districts to have or to be negotiating boundary agreements. DOH made the same comment when Renton's Water System Plan was reviewed and we expect a similar comment from King County during the review of our Long-Range Wastewater Management Plan. CRWSD 1P.DOC/ CITY OF RENTON & CEDAR RIVER WATER AND SEWER DISTRICT FOR THE ESTABLISHMENT OF SERVICE BOUNDARIES THIS AGREEMENT is entered into this day of 19 , by and between CEDAR RIVER WATER AND SEWER DISTRICT, a Washington municipal corporation, hereinafter referred to as "CRWSD", and the CITY OF RENTON, a Washington municipal corporation, hereinafter referred to as RENTON".

We look forward to attending the Utilities Committee meeting. We will have one Commissioner,Kelly Snyder, and myself in attendance. Please notify us of-the time and location of the meeting.

Warren, City Attorney Date: January 7, 1999 Subject: Interlocal Agreement with Cedar River Water and Sewer District By memo dated December 31, 1998, received by my office on January 4, 1999, you ask me to review an agreement establishing service boundaries between the City of Renton and Cedar River Water and Sewer District. I approve that document as to legal form. You ask two questions, the first related to section 5 and the use of the term "when appropriate." You feel that this language would allow the City to change its policies about requiring an extension of water and sewer mains. Your question relates to a possible takings argument by requiring property owners to extend their facilities to the far side of their property. I certainly believe that the language is of assistance. It may not be necessary, however, if a court made a ruling that requiring the extension was a taking. A counter-argument can be made, so I think the language is appropriate in the agreement. The second question relates to section 6 and the granting of an interim franchise for recently annexed properties. The concept is valid and acceptable. If you have any further questions please let me know. Lawrence J. arren LJW:as. cc: Jay Covington A8:153.01.

The City provides water service to an area of approximately 17.25 square miles and maintains more than 300 miles of pipe, 3,800 fire hydrants, and 18,000 water meters. Because of the inherent complexity of a large water system with aging infrastructure, the City has implemented a water loss control program to investigate and reduce the water lost throughout the distribution system. The City has prepared this Water Loss Control Action Plan (WLCAP) in accordance with Washington Administrative Code (WAC) 246-290-820. This Plan supplements the City’s 2019 Water System Plan and updates the 2008 WLCAP. This document summarizes the City’s progress in minimizing distribution system leakage (DSL) and includes planned activities for further reducing water loss. In 2018, the City’s DSL was approximately 10.0 percent with a rolling 3-year average of 10.7 percent. If the 3-year average DSL is greater than 10 percent, the City must have a written water loss control plan. In addition to reducing water loss, the implementation of this plan may help reduce costs to the Water Utility. The City is committed to decreasing water loss and strives to reduce DSL to 10 percent or less (3-year average) by 2022. II.OVERVIEW OF WATER LOSS Water loss in the distribution system can be attributed to a combination of real loss and apparent loss of water, both of which must be carefully assessed in order to create the most effective water loss reduction program. According to the Water Loss Control Manual 1, real loss involves the physical loss of water from the distribution system up to the point of customer metering. This includes leaks, breaks, and overflows which can be caused by a variety of reasons such as: pressure, corrosion, incorrect materials, weather, and poor maintenance. In real loss situations, the amount of leakage can be exacerbated by rate of flow and duration of the leak. Apparent loss consists of unauthorized water use and all inaccuracies associated with customer and production metering. Examples of apparent loss include errors in water flow measurement, errors in water accounting, and unauthorized usage. Problems associated with water loss can be both technical and financial in nature. The technical issue with water loss is that the customer does not receive all of the water supplied by the Utility. Financially, water loss is a problem because not all of the water reaching the end user is properly measured or paid for. There are some water uses that the City does not bill for, such as water used during the draining and cleaning of City-owned water tanks and reservoirs. These unbilled water uses are known as authorized consumption. The combination of real losses, apparent losses, and authorized consumption is called non-revenue water. 1 Sources: Thornton, J. (2002). Water Loss Control Manual. New York: McGraw-Hill. The City’s WLCAP includes measures to reduce both real and apparent water loss, and also describes examples of the City’s authorized consumption. III.ONGOING ACTIVITIES Leak Detection and Water Main Replacement The City began a proactive leak detection program in 1994. In 1999, the Water Maintenance Services Division purchased leak detection equipment, including the Subsurface Leak Correlator, and incorporated leak detection into the routine valve maintenance program. Water maintenance staff are assigned to check all of the valves within the City’s distribution system on a regular schedule and as leaks are discovered they are repaired. The City continues to conduct acoustic leak detection on City water mains and repairs these leaks as needed. In order to provide clear documentation for the Department of Health (DOH) and to facilitate communication with other City departments, the water maintenance staff has integrated specific reporting and evaluation guidelines. Leak detection testing location, date, time, name of personnel performing the test, and results of the test are recorded in the City’s asset management system. Personnel using the leak detection equipment are trained through classes. Leak detection equipment goes in for maintenance services on a yearly basis. Corrosion Control to Reduce Leakage Corrosion control treatment was implemented in 1999 to comply with the Lead and Copper Rule. Water from the Downtown Wells and Springbrook Springs is treated with sodium hydroxide to raise the pH. In addition to complying with water quality regulations, raising the pH of the water also reduces the occurrence of leaks caused by the corrosion of piping. Hydrant Repairs and Replacements The City aims to reduce water loss caused by deteriorating or malfunctioning fire hydrants. Hydrants with damaged rubber seat rings or imbedded rocks are especially at risk of non-revenue water loss. The City repairs or replaces hydrants showing signs of deterioration during routine inspections or in response to calls about visible hydrant leaks. The City will also repair or replace hydrants that are found to be leaking during acoustic testing. Continuous Consumption Customer Notification High rates of water use during “off-hours” may be a sign of unintentional continuous consumption. The City has developed a program to identify and educate customers about this water usage. When a water meter shows signs of excessive continuous consumption, the City is alerted by the Advanced Metering Infrastructure (AMI) system and water maintenance staff will physically check the meter. If the meter is working correctly yet still showing continuous consumption, water maintenance staff will provide the resident with recommendations to fix the issue by using a door hanger or sending an email. Location of Unauthorized Connections The City aims to reduce unauthorized water usage. If a City employee notices suspicious alteration of a water meter during normal Water Utility site visits, the potential unauthorized use will be reported, assessed, and fixed. The City also responds to reports of suspicious connections received from residents. Additionally, each AMI meter contains a tamper detection alarm. If a resident attempts to alter a water meter, an alarm is triggered, sending an alert to the Water Utility. The City can then investigate the cause of the alarm and assess whether any repairs to the water meter are necessary. Storage Facility Overflow Protection By utilizing alarms and overflow pipes, the City protects against water loss caused by the overfilling of water storage facilities. When the water level reaches storage capacity, a sensor is triggered, resulting in the shut off of inflow pumps. The excessive water level also triggers a “high level alarm,” which travels through both radio and fiber systems in order to ensure that the alarm signal is received by Water Maintenance Services. For each alarm triggered, water maintenance staff will respond by conducting a field inspection to locate and fix any issues. If the water rises above the trigger point and the shutoff of the inflow pump fails, an outlet located above the sensor allows for excess water to exit the storage facility through an overflow pipe. Overflow pipes carry extra water into the closest suitable facility. Visible Reported Leakage The City currently records, assesses, and investigates all reports of leaks. During normal business hours, residents can report visual evidence of leaks in the form of a phone call or email sent directly to the Water Maintenance Services. After hours, residents may call the Renton Police Department’s non-emergency number to report leakage. Electronic requests to Water Maintenance Services can be sent through the City website at: https://rentonwa.gov/city_hall/public_works/maintenance/maintenance_service_request_form Production Meters All of the City’s sources of supply are metered via production meters. This includes all of the City-owned production wells, Springbrook Springs, interties with adjacent districts, and water purchased from other water systems. Consumption Meters The City provides water service metering for all customers. Consumption meters are categorized as large water meters (3-inches or larger) and small water meters (2-inches and smaller). All large meters are tested and repaired (as-needed) on an annual basis. Small meters are repaired and replaced on an as-needed basis. Advanced Metering Infrastructure System The City finished the deployment of an AMI system in 2015, which involved installing radio transmitters in all retail water meters within the service area. Before the AMI deployment, the City suspected that much of its non-revenue water resulted from incorrect meter reads, or meters that were stuck or calibrated incorrectly. Having the AMI system improves the accuracy and efficiency of meter reading; improves the comparison of production to consumption; and better detects stuck meters, meter tampering, and water theft. Another benefit of the AMI system is that it provides more time for operations and maintenance staff to perform maintenance on meters on a more regular schedule; thus contributing to the lowering of DSL. Fixing and Replacing Inaccurate Meters As part of the WLCAP implementation, the City has been more aggressive in finding and fixing stuck registers. Registers that have been stuck for an extended period of time can result in the gathering of inaccurate customer water consumption data. Since the deployment of the AMI system, many old positive displacement-type meters with degrading accuracy have been replaced with magnetic meters, which are more accurate across their entire flow range. In the process of AMI system deployment, the City also discovered many large meters that had registers programmed to read at the wrong resolution, therefore under-registering by a factor of 10. These meters were adjusted so that all of the water consumed through them is properly accounted for. Utility Billing The City upgraded to the current billing system in 2018. This system streamlined the process of setting up Water Utility service accounts, allowing for more accurate consumption billing and history records. Interacting programs allow Utility Billing to provide the Water Utility with reports that help to detect meter issues and leaks. Utility Billing also relies on the AMI system and electronically transmitted meter reads to increase meter reading for better billing accuracy. An audit of the utility billing process has been ongoing for several years to verify the accuracy of the system’s information recording and reporting. In the past, this audit has helped to identify stuck meters and registers that are programmed at the wrong resolution. Auditing the system will likely be an ongoing process, coordinated between Utility Billing, Water Utility engineering, and the permitting system. Mapping of Leak Repair Locations The City currently records main breaks and leaks and maps their locations using GIS. This practice aids in prioritization of main replacement projects, thereby contributing to the most efficient allocation of resources for minimizing DSL. IV.ESTIMATED AUTHORIZED USES The following are authorized metered and unmetered water uses that must be subtracted from water produced along with customer consumption to determine the DSL. For each of the estimated authorized uses there is also a description of how the City is currently estimating this usage. Authorized Consumption is defined by WAC 246-290-820 and WAC 246-290-010. Water Main Flushing Water maintenance staff use hydrant meters to measure water discharged during flushing activities. This consumption is documented within the Billing System with other authorized water uses. Intertie Water Usage The water system contains 15 metered interties with neighboring water utility districts, including both one- way and two-way connections. These interties are used to supplement water during emergency situations and need to be flushed periodically to ensure high water quality. Water usage during flushing, or other operational testing events, is accounted for by the individual district and the City is notified of the amount of water used in an annual report. See Table 2.3 in Chapter 2 of the 2019 Water System Plan Update for additional information including location and flow rate for each intertie. Water Quality Analyzer Flow The City continuously measures the pH and free chlorine residual of treated water to ensure high water quality, which requires continually flowing water from a sample tap. The analyzer data is recorded by supervisory control and data acquisition (SCADA) and the results are stored in the SCADA System History database. City Maintenance Trucks There are 10 City-owned vehicles that use water for maintenance purposes: three storm vactor trucks, two sewer vactor trucks, one water vactor truck, two street sweepers, one street maintenance trailer, and one street flusher truck. Each of these maintenance trucks has a permanent, built-in meter. Currently, the water used by these maintenance vehicles is reported monthly and provided to Utility Billing for tracking. Draining and Cleaning of Water Tanks and Reservoirs The City currently records the amount of water used in the draining and cleaning of City-owned water tanks and reservoirs. Regional Firefighting Training Center (Fire Station 14) Fire Station 14, located within Renton’s water service area, is used as a training facility by approximately nine different fire agencies. Significant amounts of water may be used during training activities and is considered an authorized use by the City. In 2018, the City installed a new in-line meter to account for water used during firefighting training activities from four hydrants at the facility. The remaining two unmetered hydrants are tagged to indicate that they may be used for emergency purposes only. For further information on metering water use for non-training firefighting activities, see Planned Activities for Further Reducing Distribution System Losses. King County South Plant In 2019, the City installed two meters at the King County South Plant on the fire loop. There are 26 fire hydrants located around the site’s clarifiers and sedimentation basins, which have the potential to use substantial amounts of water. V.DISTRIBUTION SYSTEM LEAKAGE CALCULATIONS Table 1 presents the calculation for the DSL. Included in the table is the past 3 years (2016 through 2018) of water production, purchased water, customer consumption, and estimated authorized consumption. The City began tracking authorized consumption in 2011. Table 2 displays the City’s annual recorded DSL for the past 10 years. Significant improvement has been achieved since the inception of the WLCAP in 2008. In 2012 and 2013, the City achieved its goal of limiting DSL to under 10 percent, however DSL returned to above 10 percent from 2014 to 2017. The City needs to continue to lower its DSL in order to achieve the DSL standard of a rolling 3-year average of 10 percent or less.

In order to further minimize DSL within the City’s system, several additional actions or areas of focus have been identified. In order of priority, these include: 1. Calculate DSL on a Quarterly Basis 2. Develop Active Pipe and Leakage Testing Program 3. Develop Hydrant Replacement Program 4. Metering for Non-Training Firefighting Activities 5. Develop Meter Repair Program 6. Complete Transition to CityWorks for Recording Main Break and Leak Locations 7. Complete Transition to CityWorks for Recording Water Tank and Reservoir Cleaning 8. Sensus FlexNet Technology Integration Each of these activities is described in greater detail below, including the reason for selecting each activity. 1. Calculate DSL on a Quarterly Basis The City currently calculates DSL on a yearly basis for annual report requirements. It is recommended that the City increase the calculation rate to every 3 months. This increase in reporting will assist the City in understanding water loss trends so that efforts to reduce DSL can be improved. 2. Develop Active Pipe and Leakage Testing Program Leaking pipes within the distribution system can lead to higher DSL. It is recommended that the City identifies and fixes leaking pipes by comparing water use in each zone and performing leakage location testing with a listening device. At least once every 10 years, each pressure zone should be analyzed for extraneous water usage to locate specific areas of pipe leakage. Testing should occur during a time when households are using little water, such as in the middle of the night. Each zone’s usage will be compared to identify which zones need further investigation. After the zones of highest off-peak consumption are reported, it is recommended that a consultant with a listening device investigate the potential sources of leaks along the City’s distribution pipes. The hiring of a leak detection team is recommended, as it is more economically feasible than purchasing the new equipment and providing in-house training on using the new equipment. Pipes found to be leaking during the investigation can be fixed or replaced to prevent further water loss. 3. Develop Hydrant Replacement Program Leaking fire hydrants may be a large contributor to the City’s water loss. Hydrants with aging rubber seal rings or imbedded rocks are particularly at risk of non-revenue water loss through leakage. These leaks can be investigated using a listening device. The hiring of a leak detection team is recommended, as it is more economically feasible than purchasing the listening device and training in-house detectors. Active testing would allow the City to better understand which hydrants are leaking, when visual evidence is lacking. The City could then develop an annual hydrant replacement program. Currently, hydrants are checked for deteriorating or ineffective parts only during routine inspections or when notified of a leak. 4. Metering for Non-Training Firefighting Activities The City does not currently have a way to estimate the amount of water used for non-training firefighting activities. These uses can significantly contribute to DSL and therefore should be recorded. To help with accounting for this water loss, it is recommended that City water maintenance and engineering staff discuss with the fire department about the estimation and reporting of non-training firefighting activities. This would require fire department personnel to record information following each event and submit monthly reports to the City’s water maintenance and engineering staff. Each report would include the duration of firefighting activities and number of hydrants used so that an approximate flow can be calculated. 5. Develop Meter Repair Program As water meters are continually operated over time, usage readings may become less accurate. Unreliable reporting of water usage, especially with meters that analyze large amounts of water, can lead to an incorrect DSL calculation. It is recommended that large water meters be regularly tested for performance to verify that all water passing by the meter is accounted for. Large, heavily-used meters may need to be tested and/or repaired as often as once per year. 6. Complete Transition to CityWorks for Recording Main Break and Leak Locations The City currently records water main break and leak repairs and maps their locations using GIS. It is recommend that the City fully transitions to CityWorks in order to more accurately record these potential sources of DSL. CityWorks is a data management system that can efficiently integrate information about main break and leak locations with GIS for improved utility mapping and reporting. 7. Complete Transition to CityWorks for Recording Water Tank and Reservoir Cleaning Water used during the cleaning of the City’s water storage facilities is currently recorded, however it is recommended that the City fully transitions to using CityWorks for improved documentation and integration with GIS. 8. Sensus FlexNet Technology Integration The City’s AMI system is currently provided by Sensus FlexNet technology. FlexNet systems can give water utilities portable acoustic leak detection capability. For further water loss control, it is recommended that the City integrate FlexNet acoustic leak detection technology into the leak detection program. VII.SCHEDULE AND BUDGET FOR ACHIEVING DSL STANDARD The City’s goal is to maintain DSL at or below 10 percent annually and achieve a rolling 3-year average DSL at or below 10 percent to comply with regulation standards by the end of 2022. Table 3 identifies the planned schedule for implementation of each of the water loss control activities. Implementation of some of the activities, such as mapping of leak repair locations, require less effort and will likely be more easily implemented. Other activities may be more challenging to implement and therefore take longer due to budgetary and/or staff limitations. This is discussed more fully in the last section of this document. Table 4 presents the budget for the planned activities. Most of the activities do not have a budgetary cost associated with them, but in most cases staff time will be required to implement. Table 3. Schedule for Implementation of Planned Water Loss Control Activities Activity Planned Schedule Audit of City’s Utility Billing System Ongoing Calculate DSL on a Quarterly Basis Beginning January 2020 Metering Estimates of Water Use During Firefighting Activities (not at the training facility) Beginning January 2021 Annual Hydrant Replacement Program and Feasibility Study Beginning January 2021 Sensus FlexNet Technology Integration Beginning January 2020 Complete transition to CityWorks for Mapping of Leak and Break Repair Locations By December 2021 Complete transition to CityWorks for Recording Water Tank and Reservoir Cleaning By December 2021 Table 4.

Budget The City will continue to budget the resources necessary for these water loss control projects within the Public Works budget. When additional projects arise that require a large budgeting effort, the City will work to properly address budget planning requirements. Staff Availability The implementation of leak repair location mapping will likely continue to be most strongly impacted by staff availability. Interorganizational and Outside District Coordination The Water Utility will continue to coordinate between City departments and outside districts in order to estimate firefighting activities and conduct the Billing System audit. However, additional coordination efforts often result in a longer implementation schedule and other issues. Additionally, the City will continue to provide and exchange clear documentation between Water Utility Engineering, Water Maintenance Services, and Utility Billing in order to reliably estimate water losses. The importance of clear documentation is essential for calculating authorized uses that can be subtracted from the total distribution system losses.

Information presented in this report supports an update of the City’s Water System Plan currently being prepared by Carollo Engineers. This report is an update to the City’s prior Wellhead Protection Plan (WHPP) and its purpose is to document known or sus- pected contaminant sites or sources within the City’s Wellhead Protection Areas (WHPAs), and to help the City understand the risks posed by these sources. Elements of this report were developed following the Washington State Department of Health (DOH) guidelines for Wellhead Protection Programs (DOH, 2010). This report documents the results of the Contaminant Source Inventory (CSI) update per- formed. This includes updates to the City’s WHPAs, results from a “windshield survey” performed by the City and PGG, and example letters to be sent to businesses and property owners within the City’s WHPAs. This work was performed, and this report prepared, in accordance with generally accept- ed hydrogeologic practices at this time and in this area for the exclusive use of the City of Renton for specific application to the study area. No other warranty, express or implied, is made. 2.0 BACKGROUND The City of Renton is located in King County, Washington, and has four distinct water sources which include: the Downtown wellfield, the Maplewood wellfield, Springbrook Springs, and Well PW-5A (Figure 1). Each water source comes from separate aquifers that are summarized below. The Downtown wellfield draws its water from the deltaic portion of the Cedar Valley Al- luvial Aquifer (from herein referred to as the deltaic aquifer), which has been designated as a Sole Source Aquifer (SSA) by the EPA since 1988. A SSA designation indicates that an aquifer supplies at least 50 percent of the water for its service area and there is no rea- sonable alternative drinking water source that exists should the aquifer become contami- nated1. The deltaic aquifer near the Downtown wellfield is composed of course-grained sands and gravels and has an average aquifer thickness of approximately 70 feet. The av- erage depth to groundwater is roughly 23 feet below ground surface (bgs) at the Down- town wellfield. Fine-grained sediments (silts and clays) or local bedrock were observed beneath the aquifer at the City production wells. Deposits overlying the deltaic aquifer are composed of silt, sand, and gravel; however, no confining layer exists above the aqui- fer and it is therefore more vulnerable to contamination than other water supply aquifers in the Renton area. Confining layers can retard the downward flow of contaminants, and thus act as protective layer overlying an aquifer. The Maplewood wellfield draws its water from the Maplewood Production Aquifer, which is a deep sand and gravel aquifer separated from the surficial aquifer by a leaky 1 With a SSA designation, the EPA reviews projects located in the SSA area that will receive federal funding to en- sure that projects do not contaminate the SSA. RENTON WHPP UPDATE FEBRUARY 2019 aquitard. The production wells at Maplewood are screened at depths between 284 and 344 feet bgs. Water discharged at Springbrook Springs is sourced from a sand and gravel aquifer un- derlying a thick sequence of glacial till. Water from the springs is collected in two infil- tration galleries, which convey the water into transmission lines. The springs exhibit a de- layed response to seasonal precipitation (City of Renton and Carrollo Engineers, 2012), which suggests that the overlying till acts as a protective fine-grained unit above the aqui- fer. Well PW-5A is completed in a deep sand and gravel aquifer zone located approximately 280 to 390 feet bgs. Stratified glacial deposits of fine-to-coarse sand and gravel layered with silt and clay exist above this aquifer. Few other wells are completed to this depth in the Well PW-5A area, and therefore the local extent and thickness of the aquifer is poorly characterized. The Well PW-5A aquifer potentially is connected to the Maplewood Pro- duction Aquifer (PGG, 1994a), but an in-depth evaluation of this connection has not been performed. 2.1 AQUIFER PROTECTION AREA BACKGROUND In 1988, the City created an Aquifer Protection Program with the intent of safeguarding the groundwater supply sources within the City. Because the City developed this program prior to DOH’s Wellhead Protection Program, the City defined its program around “Aq- uifer Protection Areas” (APAs) rather than WHPAs. Different APA zones were delineat- ed relative to the amount of contamination risk associated with an aquifer, with Zone 1 having the highest level of associated risk, followed by Zone 1 Modified and then Zone 2. In 1992, the City passed an Aquifer Protection Ordinance to limit the storage and han- dling of hazardous material in the APAs. As part of the Aquifer Protection Program, a significant amount of public outreach and education occurred to familiarize elected offi- cials and citizens with the APA concept, where they exist, and land use restrictions asso- ciated with them. In 1994 the Renton Groundwater Model was created (PGG, 1994a; 1994b), which deline- ated the Downtown and Maplewood wellfield capture zones based on the best available hydrogeologic data at the time. During the last planning period, the City redefined the extent of the APAs to be con- sistent with the delineated capture zones in the most current water system plan. The cur- rent APAs are defined as follows: APA Zone 1: Downtown wellfield 1-year WHPA APA Zone 1 Modified: 1-year WHPA for all other sources APA Zone 2: 5-year and 10-year WHPAs for all water sources Based on the historical education and outreach efforts previously performed, the City continues to refer to the Aquifer Protection Program in its outreach materials, rather than a Wellhead Protection Program (as termed by the DOH). Because this report is intended to meet DOH criteria for a Wellhead Protection Plan update, the term Wellhead Protec- RENTON WHPP UPDATE FEBRUARY 2019 tion Area (or WHPA) will be used to describe time of travel capture zones (rather than APA zones). 3.0 WELLHEAD PROTECTION AREA DELINEATION UPDATES City WHPAs were previously updated in 1998 by PGG (1998) and have not been revised since. In 1998, each of the City’s four water sources had WHPAs delineated for their 1-, 5-, and 10-year time of travel capture zones. As part of the 2018 WHPP update, the City requested that 6-month capture zones be delineated, and that updated Maplewood pump- ing rates be applied based on treatment limitations at the Maplewood Treatment Plant. The following table lists the pumping rates used for the 2018 capture zone delineation update, while Figure 1 shows the extent of the updated capture zones. Details regarding the updated pumping rates used and the method of delineation are listed below: Downtown WHPA: Pumping rates for the Downtown wellfield wells were updated from their annualized annual water right quantity (Qa) to their instantaneous water right quantity (Qi) for delineation of the 6-month capture zone. The new 6-month cap- ture zone was delineated using the Renton Groundwater Model (PGG, 1994a; 1994b). The 1-, 5-, and 10-year capture zones for the Downtown wellfield were not updated, however it should be noted that greater uncertainty exists where the capture zones ex- tend under the uplands because the Renton Groundwater Model was calibrated only to water levels in the deltaic and Maplewood Production aquifers. Maplewood WHPA: Pumping from the Maplewood wellfield was updated to reflect current usage, and therefore in addition to delineating a 6-month capture zone, the 1-, 5-, and 10-year capture zones were re-delineated. The Maplewood wellfield pumping rates were adjusted to account for the limiting water treatment capacity of 3,000 gpm at the Maplewood Treatment Plant. Typically, only one Maplewood well is actively pumping at a time, but as a conservative approach the 2018 capture zones were delin- eated using the Qi available at PW-12 and PW-17 for a total wellfield pumping rate of Source WHPA 2018 Well RW‐1 Downtown 2,200 Well RW‐2 Downtown 2,200 Well RW‐3 Downtown 2,200 Well PW‐8 Downtown 3,500 Well PW‐12 Maplewood 1,600 Well PW‐11 Maplewood 0 Well PW‐17 Maplewood 1,500 Springbrook Springs Springbrook Springs 1,050 Well PW‐5A Well PW‐5A 1,438 RENTON WHPP UPDATE FEBRUARY 2019 3,100 gpm. Capture zones were delineated using the Renton Groundwater Model (PGG, 1994a; 1994b). It should be noted that greater uncertainty exists where the cap- ture zones extend under the uplands because the Renton Groundwater Model was cal- ibrated only to water levels in the deltaic and Maplewood Production aquifers. Addi- tionally, the southernmost fingers of the Maplewood 5- and 10-year capture zones ex- tended up to 0.8 miles outside of the model domain. In this area, the capture zones were approximated based on modeled groundwater flow velocities (from the Renton Groundwater Model immediately adjacent to the area) and oriented similar to the known extent of a subsurface bedrock valley. Springbrook Springs WHPA: The Springbrook Springs 6-month capture zone was de- lineated based on the Qi of the springs. The new capture zone was defined in same manner as the previous 1-, 5-, and 10-year capture zone, which used the Darcy equa- tion with local values for aquifer thickness (50 ft), hydraulic conductivity (75 ft/day), the hydraulic gradient (0.028 ft/ft)2, and an assumed aquifer porosity of 0.25 (PGG, 1998). The 1-, 5-, and 10-year capture zones for Springbrook Springs were not updat- ed as part of this work. Well PW-5A WHPA: The 6-month capture zone delineated for Well PW-5A is based on its annualized Qa quantity and defined using the calculated fixed radius method. This is the same way in which the 1-, 5-, and 10-year capture zones were previously delineated (PGG, 1998). For this calculation, the observed screen length (105.5 ft) and an assumed aquifer porosity (0.22) were used. Capture zones presented in Figure 1 are plotted in two dimensions, while in reality they occur in the subsurface in three dimensions. The two-dimensional delineation of the Downtown WHPA is likely representative of what is occurring in three dimensions be- cause the deltaic aquifer is not overlain by a shallower aquifer. For the Maplewood WHPA, the 6-month and 1-year capture zones predominately capture water from the deep Maplewood Production aquifer, while the 5-and 10-year capture zones capture sig- nificant quantities of water from both the deep and shallow aquifers. Compared to the deltaic aquifer, this suggests that the Maplewood Production aquifer will be less sensitive to land use immediately above its 6-month and 1-year capture zones because the water captured by the production wells is mostly from the deep Maplewood Production aquifer rather than from the shallow water table aquifer (as occurs at the Downtown wellfield). The capture zone delineation methods for Well PW-5A and Springbrook Springs are two- dimensional, and therefore the occurrence of capture in three dimensions from multiple aquifers at these sources has not been further evaluated. 4.0 CONTAMINANT SOURCE INVENTORY & RISK ASSESSMENT The following sections present an inventory of confirmed and potential sources of con- tamination located within the updated WHPAs and an evaluation of risks associated with these sources. 2 The hydraulic gradient used by PGG (1998) for areas one mile or greater from Springbrook Springs was 0.01 ft/ft, and therefore the 5- and 10-year capture zones were delineated slightly differently from the existing 1-year and new- ly defined 6-month capture zones. RENTON WHPP UPDATE FEBRUARY 2019 4.1 DATA SOURCES Potential contaminant risks that lie within the vicinity of the City’s WHPAs were investi- gated and mapped primarily using data from two sources. The first source is a parcel da- tabase created by King County that contains information regarding land use, zoning, sew- age handling, and the home heating source for parcels in the county. The second source is data obtained from the Washington State Department of Ecology’s Facility / Site Identifi- cation (FSID) database, which includes state cleanup sites, federal superfund sites, haz- ardous waste generators, solid waste facilities and underground storage tanks (USTs). Supplemental information was also obtained from Ecology’s Confirmed and Suspected Contaminated Sites database, their UST database, their Toxics Cleanup Program data- base, and data regarding dry cleaners from Puget Sound Clean Air Agency. Information from these sources was classified and plotted on GIS coverages to assess whether exist- ing and potential contaminant sources were located within the vicinity of Renton’s WHPAs3. 4.2 CURRENT LAND USE AND ZONING King County’s database contains a description of the land use within each parcel in the study area. A GIS analysis and database query were used to identify land uses present in the City WHPAs that are thought to pose elevated risk to groundwater. Parcels where such land uses were identified were designated “parcels of possible elevated risk.” Table 1 summarizes County land use categories that are considered to be of concern (primarily based on potential contaminant sources identified by DOH (2010)) and Table 2 summa- rizes the individual parcels with those categories within the WHPA. Figure 2 shows the distribution of zoning throughout the study area, and Figure 3 pro- vides a close-up of zoning in the Downtown WHPA. It also shows the parcels of possible elevated risk that occur within the City’s capture zones as green cross-hatched areas. A summary of the distribution of parcels of possible elevated risk is presented in the table below. In total, 96 parcels of possible elevated risk were identified based on County land use screening codes. Parcels of possible elevated risk that fall within the various capture zones should be considered possible contaminant source locations, with parcels in shorter time of travel zones being more pressing to evaluate for risk management. However, giv- en that some County land-use categories are quite broad, many of these parcels are likely not of significant hazard, and in general these parcels of possible elevated risk are of low- er risk than sites with known or potential contaminant sources onsite as identified in Sec- tion 4.3. 3 Some locations from Ecology’s FSID database were adjusted based on facility address, parcel information, and Google Earth imagery. RENTON WHPP UPDATE FEBRUARY 2019 Travel Time (years) Number of Parcels of Concern within WHPA DT MPW SBS 5A 0.5 9 4 2 0 1 7 5 1 0 5 31 17 0 3 10 13 3 1 0 Current zoning information from the County’s GIS was also used to evaluate current and future land use in the study area. The following zoning categories are mapped on Figures 2 and 3: Industrial Commercial Residential Open Space The Downtown WHPA is primarily zoned commercial, though residential and industrial are also major land use types. The most commonly zoned land use within the Maplewood WHPA is residential, followed by open space. In the Springbrook Springs WHPA, the predominant zoning type is residential, followed by commercial and open space. In the Well PW-5A WHPA, the predominant zoning type is residential, followed by open space. Areas zoned as commercial and industrial are the most likely to comprise threats to groundwater quality. 4.3 CONTAMINANT SOURCES Table 3 summarizes known environmental sites of potential concern within the Renton WHPAs. As mentioned in the previous section, these sites of potential concern are con- sidered of higher risk than the parcels of possible elevated risk listed in Table 2. In total, 85 active contaminant sources of potential concern to the water supply were identified within Renton’s WHPAs. These sites were identified using Ecology’s FSID database. The FSID entries for the Renton area were sorted based on their interaction type, and sites with relevant interaction types were flagged and mapped. Appendix A lists the FSID interaction types that may pose risks to groundwater. Mapped site locations were then verified (and in some cases updated) using a Google Maps address search. Figures 4 and 5 display the location of each of these sites and indicates through the location symbols which types of activities or risk are associated with each site. Each site marker has three pie slices which indicate the type of activities actively associated with the site as follows: RENTON WHPP UPDATE FEBRUARY 2019 Underground Storage Tank (UST) or Leaky Underground Storage Tank (LUST) Cleanup Site (State Cleanup or Voluntary Cleanup) Hazardous Material Generator or Handler Any combination of the three indicators is possible. Sites with ongoing cleanup actions have a red circle surrounding the pie to emphasize the risk associated with these facilities. Site markers without any pie slices filled in indicate the facility is tracked in Ecology’s facilities database, and the facility type is considered to have risk to groundwater, but the facility is not a cleanup site, a hazardous materials handler, nor does it have registered underground storage tanks. Numerous sites in the Renton area previously were tracked as cleanup sites but have re- ceived a No-Further-Action (NFA) determination from Ecology. A NFA letter signifies the site cleanup efforts have met standards in WAC 173-340 and the site does not pose a threat to human health of the environment. Though effective remedial actions have oc- curred at these sites, residual contaminants that may be present could be mobilized if re- medial controls (such as impermeable coverings) are disrupted due to neglect or redevel- opment. Therefore, the City should consider continued tracking of NFA sites so that when there is a proposed development on a NFA site, additional review occurs (in the form of reviewing environmental covenants and/or final closure documents for the site) as part of granting a building permit to ensure that the new land use does not inadvertent- ly mobilize residual contaminants. In total, 79 NFA sites are present in the Renton WHPAs and are listed in Appendix B. 4.3.1 Contaminant Sources with Known Releases Table 3 includes 30 confirmed sites with known active contaminant releases occur in Renton’s WHPAs. Active contaminant release sites are shown on Figures 4 and 5 with a red circle surrounding their respective contaminant pie. Because the majority of these sites have confirmed groundwater contamination, they pose a higher level of risk to Ren- ton groundwater quality than any other sites identified in this report. Additional infor- mation from the Department of Ecology for each active cleanup site tracked by Ecology is provided in Appendix C. Some sites listed on Table 3 currently handle hazardous materials or have UST, but pre- viously were cleanup sites and have now received NFA letters from Ecology indicating that the site has been remediated. Where this has occurred, “No Further Action” will be listed under the “Cleanup Status” column on Table 3. 4.3.2 Potential Sources Potential contamination sources within the WHPAs and discussed in this section are based on Ecology’s FSID database, Ecology’s Underground Injection Control (UIC) da- tabase, and King County’s parcel database (which includes septic data and home heating oil tank data). The following potential contamination sources have been identified within capture zones for the Renton wells: RENTON WHPP UPDATE FEBRUARY 2019 Hazardous materials Underground storage tanks On-site septic systems Home heating oil tanks Stormwater Agriculture, golf courses, and parks Unused and improperly constructed wells Transportation corridors Pipeline spills 4.3.2.1 Hazardous Materials The commercial use of chemicals poses a threat to groundwater quality, since chemicals can accidentally spill or be disposed of improperly. The likelihood of such releases from spills can be reduced by proper methods of handling, spill prevention measures, and emergency response strategies. Risk reduction strategies should target on-site handling and waste management practices. Improper disposal is likely the most common pathway for chemicals to be released into the environment. The following facility activity classifi- cations were used to identify sites with hazardous material for this assessment: RENTON WHPP UPDATE FEBRUARY 2019 FSID Activity Code Definition HWG Facilities that generate any quantity of a dangerous waste. They may be classified as small, medium or large quantity generators (SQG, MQG, or LQG) depending on hazardous waste generated for a given month. HWP Under Chapter 173-307 WAC, facilities that report under Section 313 of the Emergency Planning/Community Right-To-Know Act (EPCRA), or that generate more than 2,640 pounds of hazardous waste per year, must prepare Pollution Prevention Plans. HWOTHER Facilities that are required to have a RCRA Site ID# but who do not generate and/or manage hazardous waste (XQG generator status). This includes transporters, used oil recycler's, and dangerous waste fuel marketers and burners. HWTRNSFR Transfer facility is a site, owned, leased or operated by a transporter of regulated hazardous waste shipments where any of the following oc- curs: 1) receives wastes from another transporter, 2) transfers wastes from one transport vehicle to another, 3) transfers waste from one con- tainer to another, and 4) stores waste within a vehicle or on property for 10 days or less. Examples of transfer facilities include a parking lot, warehouse, truck terminal, barge or steamship loading and unloading facility, or railroad spur loading or unloading facility. HWTSDF Facilities that treat store or dispose hazardous waste. RSVP The Hazardous Waste and Toxics Reduction Program engages in a variety of field work, site visits, and contacts with sites. While most compliance related activity is recorded into the EPA's RCRAInfo sys- tem, the other types of activities are recorded into the Revised Site Visit Program (RSVP). TIER2 Businesses that store 10,000 pounds or more of a hazardous chemical or 500 pounds or less, depending on the chemical, of an extremely hazardous chemical on site at any one time must report annually. Re- ports are sent to the State Emergency Response Commission [repre- sented by Ecology], Local Emergency Planning Committees, and local fire departments for emergency planning. [product, not waste] TRI Facilities in specific industries that manufacture, process or use more than the threshold amount of one or more of 600 listed toxic chemi- cals. Most threshold amounts are 10,000 or 25,000 pounds per year. Some chemicals have much lower thresholds. The most significant threats to groundwater are related to the use and storage of solvents. Solvents are persistent and relatively mobile. A large plume of contamination can be cre- ated with a small quantity of solvent. The FSID database indicates that there are 43 sites within the Renton WHPAs that are ac- tive and fall into one of the above hazardous material classifications. These are included in Tables 3 and 4, with Table 4 further identifying the hazardous material classification for each site and whether the site has more than one hazardous material activity occurring RENTON WHPP UPDATE FEBRUARY 2019 on it. The facility site index database does not indicate whether sites listed are large, me- dium, or small hazardous waste generators. One site presumably handling hazardous ma- terials but not identified in Ecology database is the Puhich Dry Cleaner Site. This site was observed during the Windshield Survey (described below in Section 4.4) as having sever- al new monitoring wells which suggests possible monitoring for PCE (the most common contaminant associated with dry cleaners). The site was therefore added to Tables 3 and 4. The City should contact the owners of Puhich Dry Cleaners to confirm this assump- tion. 4.3.2.2 Underground Storage Tanks Contamination in soil and groundwater caused by leaking USTs (“LUSTs”) is a major environmental, legal, and regulatory issue. Common causes of leaks are structural failure, corrosion, improper fittings, improper installation, damage, and natural phenomena. Alt- hough USTs are typically used to store flammable motor fuels or heating oils, they may be used for other compounds used by industry, government, or business. Leakage from USTs and associated piping can often occur without detection. Even rela- tively small amounts of certain compounds can adversely impact groundwater quality. Once released from an UST, some petroleum products and volatile organic compounds can rapidly migrate to groundwater, a problem that is especially serious in areas with permeable soils or that directly overlie a water supply aquifer. Of the many materials stored in USTs, solvents are considered the most toxic. However, petroleum products may pose a greater total risk because their use is far more prevalent. In addition, petroleum products contain many potential contaminants, including three EPA priority pollutants: benzene, toluene, and ethylbenzene. Benzene is a known human carcinogen. Figures 4 and 5 show the locations of USTs in the WHPAs. These sites were identified from Ecology’s UST site data and Toxics Cleanup Program database. Most of these sites exist in areas zoned industrial and commercial. Currently, 34 active USTs facilities locat- ed within the wellhead protection capture zones. Of the 34 active UST sites, there are 11 large facilities (>15,000 gallons total volume) in operations (Table 3). The tanks at these large facilities have been upgraded to standards developed in the mid-1990’s and include double-walled tanks and leak detection systems. In total, sixteen active LUST sites from the Ecology database are located within the WHPAs. 4.3.2.3 On-Site Septic Systems On-site septic systems pose a risk to groundwater where they are relatively high in densi- ty and/or where hazardous wastes are discharged to them. Potential contaminants from septic systems include pathogenic organisms (bacteria and parasites), toxic substances, contaminants of emerging concern (CECs), and nitrogen compounds. The extent to which pathogens are transported in the subsurface away from a septic drain field depends on the type of pathogen and the chemical and physical conditions in the subsurface. In general, if a septic system is properly sited, constructed, and maintained, the transport of microorganisms will be limited. Household hazardous chemicals such as cleaners, polishes, waxes, and paints can be transported to groundwater via a septic sys- RENTON WHPP UPDATE FEBRUARY 2019 tem. Some products contain toxic and persistent chemicals that can cause low-level con- tamination when coupled with a high density of septic systems. Homeowners may im- properly apply or dispose of chemicals because they do not understand the threat they pose to groundwater quality. In some areas, business and commercial facilities use on-site septic systems for sewage disposal. Business, commercial, and industrial operations that utilize on-site systems need to take special precautions to avoid contamination of their wastewater. Septic systems can also be sources of CECs, which generally are not hazardous chemi- cals, but can present in wastewater at low concentrations. CECs include pharmaceuticals, personal care products, food additives, cooking products, flame retardants, and various commercially and industrially used compounds. These compounds are not always re- moved by wastewater treatment plants or septic tanks, and therefore are often detectable in groundwater and surface water. Research into CECs and their potential impact to hu- mans and the environment is ongoing and Ecology, DOH and EPA may periodically ad- just their requirements as more becomes known about the risks posed by these contami- nants. Ammonia and nitrate are highly soluble in water and can be expected in detectable quan- tities wherever portions of an aquifer are affected by septic system discharges. Septic sys- tems are a source of nitrate in groundwater throughout King County. Nitrate is regulated, since ingestion can result in methemoglobinemia, or “blue baby” syndrome. Other sources of nitrate include fertilizers, feedlots, and natural mineral deposits. Background concentrations of nitrate in groundwater are typically less than 1 milligram of nitrogen per liter (mg-N/L). Shallow wells typically are more susceptible to nitrate contamination since they are closer to surficial sources and less aquifer dilution occurs near the water table. The maximum contaminant level (MCL) for nitrate is 10 mg-N/L. Most of the Renton area is served by sewer systems, however, residents in some local neighborhoods and streets within the WHPAs still rely on septic systems. The King County Assessor’s database indicates if a given property is served by a septic system. Properties with septic systems are plotted on Figures 2 and 3. Table 5 summarizes the distribution of septic systems with the City’s WHPAs and indicates that a total of 1,075 properties within the City WHPAs are on septic systems. The greatest number of septics occurs in the Springbrook Springs WHPA, followed by the Maplewood WHPA and the Well PW-5A WHPA. Virtually no septic systems exist in the Downtown WHPA. A comparison of mapped septic parcels to land use zoning areas (Figures 2 and 3) suggests that no septic systems are located on properties zoned for commercial or industrial uses. 4.3.2.4 Home Heating Oil Tanks Data from the King County assessor’s office was obtained regarding the heat source of the primary building located on each parcel. Properties using heating oil were mapped as locations that most likely have home heating oil tanks on site and are shown in Figures 2 and 3. In total, 892 parcels with home heating oil tanks are located with the City WHPAs. Most of these parcels (333) are located in the Downtown WHPA, followed by Well PW-5A (275), Springbrook Springs (180), and Maplewood (104) WHPAs. Home heating oil is a heavier mixture of hydrocarbons and is generally less soluble in water than gasoline. Home heating oil tank leaks are typically more localized than gaso- RENTON WHPP UPDATE FEBRUARY 2019 line or diesel leaks from service stations since the tanks are significantly smaller and the hydrocarbon mixture is less mobile. Historically, no documented groundwater contami- nation has occurred in Renton due to home heating oil tank leaks (PGG, 2012). There- fore, based on the smaller quantities and lower mobility of home heating oil in the envi- ronment, the risk of contamination to production wells caused by home heating oil tank leaks is considered low, though future leaks causing contamination remain possible. Be- cause the deltaic aquifer is relatively shallow, unconfined, and overlain by a dense distri- bution of home heating oil tanks, educational outreach to homeowners regarding home heating oil tank maintenance and spill cleanup procedures is recommended within the Downtown wellfield 1-year WHPA. 4.3.2.5 Stormwater Stormwater (i.e., urban runoff) is produced when rainfall or other precipitation accumu- lates faster than it can evaporate, be used by plants, or infiltrate to the subsurface. Urban areas produce more runoff than rural areas because they have more impermeable surfac- es, such as rooftops, driveways, streets, and highways. Even grass lawns can produce more runoff than forests and pasture. Stormwater typically contains pollutants, such as sediment, nutrients, bacteria, oils and grease, metals, and other toxics. Many of these contaminants come from air pollution, motor vehicles, application of pesticides and fertilizers, soil erosion, and animal feces. Roofing materials have also been identified as a diffuse source of metals in runoff, par- ticularly zinc (Good, 1993). In general, contaminant concentrations in urban stormwater are similar for all land uses, though slightly higher nitrate concentrations occur in resi- dential areas and higher heavy metals concentrations occur in commercial areas. Concen- trated sources of stormwater contamination may also occur if undiluted pollutants (e.g., fertilizer, gasoline, etc) are accidentally spilled or intentionally released and enter storm drains. Stormwater contamination typically is of concern for surface water pollution because most urban runoff is directed to streams, lakes, and other water bodies with fish and other aquatic life that are highly sensitive to common stormwater contaminants. Infiltration of stormwater generally results in some contaminant treatment, but could still pose risks to groundwater quality depending on the types and concentrations of contaminants present in the stormwater. Potential Risk from Stormwater Concern over potential groundwater contamination from stormwater has been recognized by several governmental agencies in western Washington. Stormwater-related impacts to water quality are of particular concern in industrial, commercial, and high-density resi- dential development areas, where runoff volumes can be large. Consequently, stormwater runoff from highways and roads can introduce contaminants such as EPA-priority pollu- tants (heavy metals and numerous organic compounds), pesticides/herbicides, and coli- form bacteria into the groundwater system. Stormwater runoff from lawns and agricultur- al areas may also introduce nitrate, herbicides, pesticides, and bacterial contaminants. RENTON WHPP UPDATE FEBRUARY 2019 Stormwater Management in the Renton Area Stormwater infiltration is prohibited in APA zone 1 and restricted in APA zone 2, and therefore much of the stormwater in Renton is routed to the Cedar River via dedicated a stormwater system. Surface water will generally convey stormwater contaminants outside of City WHPAs, though sediment deposition or local surface water-groundwater interac- tions may cause stormwater contaminants to locally remain within the WHPAs and/or en- ter groundwater. Given that the Cedar River is losing adjacent to the Downtown well- field, it is possible that dissolved contaminants within stormwater runoff could enter the City’s water supply. Though stormwater contaminants would be greatly diluted in the Cedar River and further diluted in the deltaic aquifer, additional study of this potential contaminant pathway should be considered. Historically, no groundwater contamination attributed to stormwater has been identified at City water supply sources. Drywells are stormwater handling facilities intended to infiltrate captured stormwater di- rectly into the ground in a shallow well (as compared to a stormwater basin which allows infiltration and evaporation in a shallow depression). Ecology’s UIC database was re- viewed to identify the location of drywells within the City’s WHPAs. Within the UIC da- tabase, 12 active drywells were identified. UIC drywell locations are shown in Figures 2 and 3. Drywells can provide a shortened pathway for contaminants present in stormwater to reach the uppermost aquifer. Stormwater that is infiltrated through drywells may re- ceive less treatment and filtration than stormwater infiltrating through soils because of this. However, in some cases varying degrees of stormwater treatment may occur via bi- oswales or through engineered treatment vaults prior to infiltration through a drywell. In addition to UICs identified by Ecology, 17 additional stormwater infiltration structure locations (provided by the City and King County) within the WHPAs are mapped in Fig- ures 2 and 3. Infiltration basins can pose less of a threat to groundwater quality than dry wells since a greater thickness of sediments usually exist between the basin bottom and the water table. However, infiltration basins may infiltrate a larger quantity of water than dry wells, and therefore the relative risk of a dry well versus an infiltration basin should be evaluated on a case-by-case basis. Lastly, Ecology’s FSID database lists sites having general stormwater discharge permits, with categories that include large construction sites, industrial sites, municipal storm- water systems, and WSDOT facilities (listed in Appendix A). General stormwater dis- charge permits were not included with potential hazards sites based on the reasoning that all sites within a WHPA have stormwater draining to state waters, and therefore storm- water pollution risks are not limited to only large permitted sites. 4.3.2.6 Agriculture, Golf Courses, Parks, and Lawns Fertilizers, pesticides, and herbicides are applied to residential lawns, commercial land- scaping, agricultural lands, and landscaped areas adjacent to roads. If optimally applied, these chemicals pose little threat to groundwater, however, applications are commonly made incorrectly and groundwater contamination can result if agricultural chemicals are applied in exceedance of the agronomic rate. Excess nitrate from fertilizer will be carried in water infiltrating to the underlying groundwater system. Frimpter and others (1990) es- timated that an average of 9 pounds of nitrate-N leached annually to groundwater from RENTON WHPP UPDATE FEBRUARY 2019 each 5,000-square-foot lawn. Landscaping activities can also be the source of pesticides and herbicides. Residential lawns and other landscaping occur throughout the Renton WHPAs. These are potential sources of nitrogen, pesticides and herbicides to the groundwater. The risk of groundwater contamination by these contaminants is moderate because much of the City’s water supply aquifer is overlain by glacial till or confining layers, except for with- in the Downtown Wellfield WHPA. Agricultural activities in the Renton WHPAs are limited, though some small farms are located in the Springbrook Springs WHPA in the vicinity of SE 196th St. The application of fertilizer and pesticides/herbicides in agriculture can potentially pose threats to groundwater quality. Public parks, schools, and sports complexes were all identified within Renton WHPAs, and the application of fertilizers and pesticides/herbicides at these sites can negatively impact groundwater quality. Some of these parks are within wellfield 6-month time of travel zones (such as Liberty Park and Cedar River Park), and therefore the City should coordinate with the parks department on the use of chemicals at facilities in close proxim- ity to wellfields. The Maplewood Golf Course is located within the Maplewood wellfield 6-month WHPA, and is likely receiving fertilizer, pesticide, and/or herbicide applications. However, the Maplewood wellfield wells are deep (approximately 284 feet bgs to the top of the screened interval) and separated from the surficial aquifer by an aquitard. Historically, the wells have not had a nitrate-N concentration exceeding 0.5 mg/L. Therefore, the risk of nitrate or pesticide/herbicide contamination to the Maplewood wellfield wells is con- sidered low. 4.3.2.7 Unused, and Improperly Constructed Wells Improperly constructed or abandoned wells pose several potential problems. Unused wells that have not been properly decommissioned can provide a conduit between the ground surface and underlying aquifers. In wells with no surface seal, contaminants in- troduced near the wellhead can move downward outside the casing to underlying aqui- fers. Many older wells that were constructed before the implementation of the State’s minimum well standards in WAC 173-160 in 1971 have no surface seal. Abandoned wells pose a special risk if they are left without a sealed cap because contaminants can be introduced directly into the aquifer. Unused wells also pose a risk when they are damaged during site redevelopment. Any of these situations can provide a conduit for contaminant movement. An inventory of abandoned wells in the study area is beyond the scope of this project. 4.3.2.8 Transportation Spills Vehicles transporting hazardous material can be a source of groundwater contamination through accidents and resultant chemical spills. Hazardous materials are transported through Renton on a daily basis. The major transportation routes in the City WHPAs in- clude: RENTON WHPP UPDATE FEBRUARY 2019 Interstate 405 State Route 167/Valley Freeway State Route 169 State Route 900 State Route 515 Rainier Avenue Grady Way Bronson Way/2nd Avenue Rail lines (primarily serving the Boeing facility) All of these transportation corridors go through at least one of the City’s WHPAs, with I- 405 (the most heavily used route) present in both the Downtown and Well PW-5A WHPAs and is in very close proximity to those supply wells. Historically, a tanker truck overturn on I-405 in 1983 resulted in a relatively small spill (500 gallons) of petroleum product, some of which entered the Cedar River via storm sewer in the vicinity of the Downtown wellfield (PGG, 2012). A major spill along any of these routes could adverse- ly impact groundwater pumped from these supply wells, particularly at the Downtown wellfield since it is shallow and lacks overlying aquitards. Spill response plans are of critical importance in protecting the City’s sources. Response planning should be coordinated between the City, first-responder emergency services (fire, police and state patrol), Ecology and DOH. A formal spill response plan should be regularly updated, and first-responder units should be provided with maps showing the City’s APA and WHPA areas to help ensure proper coordination that will protect the wa- ter resources in the event of a spill. 4.3.2.9 Pipeline Spills Several large pipelines exist in the City’s WHPAs and have historically had spills associ- ated with them. Pipelines are also at risk to earthquake damage. Figures 2 and 3 show the locations of the Olympic Pipeline and King County Sewer mainlines. The Olympic Pipeline (OPL) crosses through the 1 year Maplewood wellfield WHPA and through a small portion of the Downtown wellfield 5 and 10 year WHPAs. In 1986 a failed block valve on the OPL caused approximately 80,000 gallons of petroleum product to leak from the pipeline, which was eventually discovered due to seepage into the Cedar River. Following the installation of over 50 monitoring wells and remediation using nu- merous air sparge and soil vapor extraction wells (PGG, 2012), the spill site was granted a NFA from Ecology in 2015. In 2002, a large (42-inch diameter) sanitary sewer trunk line was punctured by a drill rig during construction along the Maple Valley Highway. Approximately 50,000 gallons of sewage and landfill leachate was spilled just north of Cedar River Park in the area be- tween PW-9 and the Henry Moses Aquatic Center, which is within the 6-month WHPA for the Downtown wellfield. However, contaminant migration from this spill was limited RENTON WHPP UPDATE FEBRUARY 2019 and was only detected in groundwater a few feet from the break and only for a few days following the break (PGG, 2012). Smaller side sewer pipelines can also pose a potential contamination risk. In 1988 a side sewer line in Cedar River Park near PW-8 was unknowingly broken during the construc- tion of the Renton Community Center, and for several months intermittent coliform hits were detected in nearby PW-8 (PGG, 2012). Though pipeline spills are relatively rare and historically have resulted from malfunctioning equipment or construction damage, if a leak is not identified quickly, the risk of aquifer contamination is greatly increased. 4.4 WINDSHIELD SURVEY FINDINGS On November 28, 2018 City and PGG personnel performed a windshield survey of sites of interest identified by the City during review of the initial inventory results and those recommended by PGG as a result of our analysis. The sites fell into the following catego- ries: High priority sites identified by the City Sites with ongoing contaminant cleanups Dry cleaners In total, 30 sites meeting one of the above criteria were visited. Several additional lower priority sites in close proximity to these were also visited. Site names and addresses were confirmed or updated during this process, and general observations and the presence of observed monitoring wells were noted as part of the survey. Cleanup sites and dry clean- ers visited during the windshield survey along with associated field notes are listed in Table 7. Based on the windshield survey, one additional site (Puhich Dry Cleaners, with map ID 70) was added to the list of sites of potential concern. 4.5 WHPA NOTIFICATION LETTERS In an effort to protect and coordinate spill response planning within the City’s WHPA, notification letters (which presents a WHPA map and describes appropriate procedures in the event of a spill) should be sent to the following entities: Parcels of Possible Elevated Risk within WHPAs (Table 2) Owners of Active Environmental Sites of Potential Concern within WHPAs (Table D-1). It should be noted that some overlap exists between Table 2 and Table D-1 sites for sites that were identified both as a possible hazard based on land use and a potential hazard based on Ecology data. Local Fire and Police Department Washington Department of Ecology Copies of potential notification letters are provided in Appendix D.

Lawn & garden supplies such as fertilizer bags also may be stored outside and could result in high nutrient concentrations in runoff. Several general categories (including warehouse, industrial park, service building, mini warehouse, and historic warehouses) were included they may use or store hazardous chemicals. Table 1.

The 5 and 10 year WHPAs for the Downtown and Maplewood well fields overlap; if a hazardous site is located where the WHPAs overlap, the WHPA is denoted as DT/MPW. TIER 2 = facility stores 10,000 pounds or more of a hazardous chemical, or 500 pounds or less (depending on the chemical) of an extremely hazardous chemical on site at any one time. TRI = facility manufactures, processes or uses more than the threshold amount of one or more of 600 listed toxic chemicals. Most threshold amounts are 10,000 or 25,000 pounds per year. Some chemicals have much lower thresholds. Facility names in parentheses indicates that a site was visited during the windshield survey and it has a different name from the FSID facility name (which is in parentheses).

Table A‐1. Ecology Facility Site Database Interaction Types and Potential Hazards Posed to Groundwater Renton WHPP Update ACRONYM INTERACTON TYPE DEFINITION WHPA Risk? Hazardous Materials? Cleanup Site?UST/LUST? DAM Dam Site Under state law, the Department of Ecology is responsible for regulating dams that capture and store at least 10 acre‐feet of water or watery materials such as mine tailings, sewage and manure waste. Ecology's Dam Safety Office currently oversees about 870 dams across the state through plan reviews and construction inspections of new dams as well as conducting inspections of existing dams to assure proper operation and maintenance. Note: Professional judgement was applied in creating this list of potential groundwater hazards. It assumes that groundwater and surface water are in direct continuity, and therefore applications of pesticides or herbicides to surface waters could impact groundwater. General stormwater discharge permits were not included as potential hazards since stormwater from all sites within WHPAs potentially drain to state waters, and therefore stormwater pollution risks are not limitted to only permitted sites .

The Plan is based on Washington Department of Health WAC 246-290-135(3) regulations. As part of the Plan, maps were prepared that show the areas around each city drinking water source where a chemical spill on the ground may cause contamination of the aquifer. These areas are Aquifer Protection Areas (APAs). The Plan also requires an inventory of potential sources of groundwater contamination within these APAs. The primary purpose of this letter is to notify you that your facility is located within one of our APAs. Since your business or the activities conducted at your facility may involve the use of chemicals (e.g., gasoline, underground storage tanks, hazardous materials, etc.), and the potential exists that a chemical spill from your facility may adversely impact the City drinking water supply, please notify the City of Renton immediately if a chemical spill occurs at your facility. All spills should be reported by dialing 911 and requesting that the City of Renton Fire Department and that Public Health Department for Seattle & King County be contacted. Thank you for assisting us in protecting our water supply and groundwater resources. If you have any questions, please contact me at (425) 430-7335.

The Plan is based on Washington Department of Health WAC 246-290-135(3) regulations. As part of the Plan, maps were prepared that show the areas around each city drinking water source where a chemical spill on the ground may cause contamination of the aquifer. These areas are Wellhead Protection Areas (WHPAs). The enclosed map depicts the WHPA boundary, source wells, and identified potential contaminant sources. Also enclosed is a table (Table D-1) providing the facility ID, name and location for each potential contaminant source. Please review the map and use it as a reference when inspecting and permitting the storage, use, and disposal of hazardous material within our WHPAs. Please note that the City of Renton has sent notices to each of these properties informing them of their location within the WHPA boundary. The City has also sent similar letters to businesses with land uses that could potentially contaminate groundwater quality. Thank you for your attention in this matter.

Introduction Providing safe, clean drinking water is one of Renton’s highest priorities. Our municipal water system produces an average of 7.3 million gallons of water each day and serves over 68,000 customers. A cross connection is created when municipal drinking water supply piping connects to various plumbing fixtures or equipment. If improperly protected, contamination of the water supply can result when a backflow event occurs. To ensure public health protection, the City of Renton (City) requires backflow prevention and has established a Cross Connection Control Program. The City has a certified Cross Connection Specialist that administers the program and manages compliance for over 4,000 backflow assemblies. The City has prepared this Cross Connection Control Plan in accordance with Washington Administrative Code (WAC) 246‐290‐490. This document summarizes the planning, implementation, codes, and policies of the City’s Cross Connection Control Program. II. Program Elements The City’s program follows and complies with the minimum elements of a Cross Connection Control Program as identified in WAC 246‐290‐490(3). All definitions are detailed in WAC 246‐290‐010. Element 1: The purveyor shall adopt a local ordinance, resolution, code, bylaw, or other written legal instrument… Ordinance 4312 was adopted by City Council on May 13, 1991, amending City codes on “Water, Health and Sanitation” by adding a Cross Connection Control section. The ordinance established the City’s legal authority for implementing the Cross Connection Control Program. The following summarizes Renton Municipal Code (RMC) regarding the City’s Cross Connection Control Program. RMC 4‐6‐020 CROSS CONNECTION CONTROL STANDARDS: A. Purpose 1. National standards of safe drinking water have been established. The City, as a water purveyor, has the primary responsibility for preventing water from unapproved sources, or any other substances, from entering the public potable water system. (Ord. 4312, 5‐13‐1991) 2. This Section is to protect the health of the water customers and the water quality in the distribution system. This shall be accomplished by a Cross Connection Control Program that relies on premise isolation. The water purveyor will be responsible for eliminating or controlling all actual (direct) and potential (indirect) cross connections. The water purveyor shall ensure these cross connections will be eliminated or controlled by installing Washington State approved backflow assemblies commensurate with the degree of hazard. B. Applicability This Chapter applies throughout the water service area of the City. It applies to all systems installed prior to or after its enactment. Therefore, anyone wanting or using water from the City is responsible for compliance with these regulations and shall be strictly liable for all damage incurred as a result of failure to comply with the express terms and provisions contained herein. C. Authority The Administrator of the Department of Public Works will administer the provisions of the Chapter. He/she will designate Cross Connection Specialists and propound all needful rules and regulations to implement these provisions. The Water Utility Section of the Utility Systems Division will be responsible for monitoring and inspecting all existing backflow assemblies and for keeping all records generated by the Cross Connection Control Program. The Plan Review Section of the Development Services Division of the Department of Community and Economic Development will be responsible for reviewing all new and revised plans for cross connections. (Ord. 5450, 3‐2‐2009) D. Installation of Backflow Assemblies Backflow assemblies required by this Chapter must be installed and be readily accessible for maintenance and testing. All backflow assemblies shall be connected at the water meter or the property line. When water meters are not used, or within any premises where, in the judgment of the City Cross Connection Specialist, the nature and extent of activity on the premises or the materials used or stored on the premises could present a health hazard should a cross connection occur. This includes: 1. Premises having an auxiliary water supply. 2. Premises having internal cross connections that are not correctable, or complex plumbing arrangements which make it impractical to ascertain whether or not cross connections exist. 3. Premises where entry is restricted so that inspections for cross connections cannot be made with sufficient frequency or at sufficient short notice to assure that cross connections do not exist. 4. Premises having a repeated history of cross connections being established or re‐established. 5. Premises on which any substance is handled under pressure so as to permit entry into the public water system, or where a cross connection could reasonably be expected to occur. This includes the handling of process waters and cooling waters. 6. Premises where materials of a toxic or hazardous nature are handled such that if backpressure or backsiphonage should occur, a health hazard may result. 7. Hospitals, mortuaries, clinics. 8. Laboratories. 9. Piers and docks. 10. Sewage treatment plants. 11. Food or beverage processing plants. 12. Chemical plants using a water process. 13. Metal plating industries. 14. Petroleum processing or storage plants. 15. Radioactive material processing plants or nuclear reactors. 16. Car washes. 17. Process waters or cooling towers. 18. Fire sprinkler systems. 19. Irrigation systems. 20. Solar hot water systems. 21. Others specified by the Administrator of the Department of Planning/Building/Public Works. E. Specific Types of Backflow Assemblies Required in the Following Conditions 1. An Air Gap separation or Reduced Pressure Backflow Assembly (RPBA) shall be installed where the water supply may be contaminated by industrial waste of a toxic nature or any other contaminant which would cause a health or system hazard. All of these premises are detailed in Table 9 of WAC 246‐290‐490 as severe or high‐hazard facilities and will have premise isolation at the water service connection. 2. An Air Gap must be used between a potable water supply and sewer connected wastes. 3. Lawn sprinkler or irrigation systems, which are supplied by City water only, shall be required to have a Pressure Vacuum Breaker Assembly (PVBA) or a Double Check Valve Assembly (DCVA). If such system contains an auxiliary pump or is subject to chemical additives an, Air Gap separation or a RPBA will be required. F. Responsibilities of Owner and Utility 1. Water Utilities Section: a. The Water Utilities Section will perform evaluations and inspections of plans/or premises of all existing facilities. The water purveyor will inform the owner, by letter, of any corrective action deemed necessary, the method of achieving the correction and the time allowed for the correction to be made. b. The Water Utilities Section shall insure that all backflow assemblies are tested annually to insure satisfactory operation. c. The Water Utilities Section shall inform the owner, by letter, of any failure to comply by the time of the first inspection. An additional 15 days will be allowed for the correction. In the event the owner fails to comply with the necessary correction by the time of the second inspection, the Water Utilities Section will inform the owner, by letter, that the water service to the owner’s premises will be terminated within a period not to exceed 5 days. d. If the Water Utilities Section determines at any time that a serious threat to the public health exists, the water service will be terminated immediately and without notice. 2. Plan Review Section: On new installations the Plan Review Section will provide on‐site evaluation and/or inspection of plans in order to determine if cross connections exist and what type of backflow assembly, if any, will be required before a water meter permit can be issued. 3. Owner: a. The owner shall be responsible for the elimination or protection of all cross connections on his/her property. b. The owner, whether notified by the City or not, shall at his/her expense install, maintain and have tested by a Washington State certified Backflow Assembly Tester any and all backflow assemblies on his/her premises. c. The owner shall return to the City the backflow assembly test reports within 30 days after receipt of the annual test notification. d. The owner shall inform the Water Utility of any proposed or modified cross connections. e. Owners who cannot shut down operation for testing of assemblies must provide bypass piping with an additional backflow assembly at their expense. f. The owner shall only install backflow assemblies which are approved by the Washington State Department of Health. g. The owner shall install backflow assemblies only in a manner approved by the Washington State Department of Health. h. The owner may be required to install a backflow assembly at the service entrance if a private water source is maintained on his premises, even if it is not cross connected to the City’s system. i. Failure of the owner to cooperate in the installation, maintenance, repair, inspection and testing of backflow assemblies required by this Section shall be grounds for the termination of water service or the requirements of an Air Gap separation. G. Annual Inspection and Testing Requirements All RPBA, DCVA, PVBA, and Air Gaps shall be inspected and tested annually or more often when successive inspections indicate failure. All inspections and testing will be performed by a Washington State certified Backflow Assembly Tester. The backflow assembly test reports shall be returned to the City within 30 days after receipt of the annual test notification. (Ord. 4312, 5‐13‐1991) Element 2: The purveyor shall develop and implement procedures and schedules for evaluating new and existing service connections to assess the degree of hazard posed by the customer’s premises to the purveyor's distribution system and notifying the customer within a reasonable time frame of the hazard evaluation results... New Installations: As part of the City’s review of an application for water service and for the issuance of a water meter permit for domestic, landscape irrigation, fire sprinkler system, or for other water uses: 1. The Water Utility section reviews all plans for development and redevelopement projects including plans for tenant improvements of existing and new buildings and evaluates the cross connection hazards. All new multi‐family, commercial, and industrial development and redevelopment projects are required to have premise isolation by having an approved RPBA installed behind the domestic meter and as close as possible to the water meter, conforming to the City’s Water Utility Standards Details. The Water Utility may allow the installation of an approved DCVA for premise isolation, after the review of the building plumbing plans and after verification that the use of the building is not considered as severe or high‐hazard facilities per Table 9 of WAC 246‐290‐490. A DCVA is required on a landscape irrigation meter and a Double Check Detector Assembly (DCDA) is required for a fire protection service. 2. The City’s Building/Plumbing inspector evaluates the cross connection hazards from the building internal plumbing and requires the installation of proper backflow assemblies for in‐premise isolation. The Water Utility coordinates its review of the plans with the Building/Plumbing inspector when the backflow assemblies are used both for premise and for in‐premise isolation. 3. The Public Works Utility Inspector inspects the installation of all backflow assemblies installed outside of the buildings. The Building/Plumbing Inspector inspects all backflow assemblies installed inside the buildings. 4. Satisfactory backflow assembly test reports must be submitted to the Water Utility for review prior to the final occupancy of the building. Periodic reevaluations: The Water Utility Cross Connection Control Program Manager periodically reevaluates connections and assess hazards as part of the preparation and submittal of the Annual Summary Report to the Washington State Department of Health. Connections are also evaluated and hazards assessed when they are brought to the attention of the Cross Connection Control Program Manager, for example during a tenant improvement project or when a Building/Plumbing Inspector notices something of concern. Element 3: The purveyor shall develop and implement procedures and schedules for ensuring that: i. Cross connections are eliminated whenever possible; ii. When cross connections cannot be eliminated, they are controlled by installation of approved backflow assembly commensurate with the degree of hazard; and iii. Approved backflow assemblies are installed in accordance with the requirements of [WAC 246‐290‐490(6)]. The City’s Cross Connection Control Program endeavors to eliminate all actual or potential physical cross connections where possible. An approved Air Gap is required for a severe hazard facility such as the King County Wastewater Treatment Plant. RPBA are required for premise isolation on all high‐hazard facilities and on all facilities listed in Table 9 of WAC 246‐290‐490. The City has adopted codes and published standards details and procedures for the installation and testing of backflow assemblies consistent with the latest edition of the “Cross‐Connection Control Manual Accepted Procedure and Practice.” Element 4: The purveyor shall ensure that personnel, including at least one person certified as a Cross Connection Specialist, are provided to develop and implement the Cross Connection Control Program. The City’s Cross Connection Control Program Manager is a Washington State certified Cross Connection Specialist. Several staff in the Water Maintenance Services section are also Washington State certified Cross Connection Specialists and Washington State certified Backflow Assembly Testers. Element 5: The purveyor shall develop and implement procedures to ensure Washington State approved backflow assemblies relied upon to protect the public water system are inspected and/or tested (as applicable) under [WAC 246‐290‐490(7)]. The Cross Connection Control Program Manager maintains a current database of backflow assemblies installed within the water customers’ premises and at the water meters. The Cross Connection Control Program Manager sends an annual Backflow Assembly Test Notice to owners of backflow assemblies and reviews the backflow assembly test reports submitted by a Washington State certified Backflow Assembly Tester. The Cross Connection Control Program Manager notifies the owners, by letter, when a backflow assembly fails the test and requires the backflow assembly be repaired or replaced. A satisfactory backflow assembly test report must be submitted to the City. The Cross Connection Control Program Manager inspects all new installation of backflow assemblies for premise isolation. The Building/Plumbing Inspector inspects the installation of backflow assemblies inside the buildings. A hazard assessment is conducted as part of the inspection to ensure that protection is provided commensurate with the degree of hazard. A Washington State certified Backflow Assembly Tester inspects Air Gaps, RPBAs, DCVAs, DCDAs, and all other approved backflow assemblies and sends the backflow assembly test reports to the City. Element 6: The purveyor shall develop and implement a backflow assembly testing quality control assurance program, including, but not limited to, documentation of a Washington State certified Backflow Assembly Tester certification and test kit calibration, backflow assembly test report contents, and time frames for submitting completed backflow assembly test reports. The Cross Connection Control Program Manager reviews the backflow assembly test reports for completeness and accuracies. Backflow assembly test reports must be submitted within 30 days of completing the test. If information is missing on the backflow assembly test report, or errors are found, the Cross Connection Control Program Manager notifies the Washington State certified Backflow Assembly Tester to resubmit a revised backflow assembly test report. The Cross Connection Control Program Manager may also inspect the backflow assembly in question. The Cross Connection Control Program Manager requires the Washington State certified Backflow Assembly Tester submit copies of their current Washington State certification and their current test kit calibration reports. This information in entered into the City database. A partial list of Washington State certified Backflow Assembly Testers in Western Washington is kept in the Cross Connection Control Program files. Copies of this partial list are available to the public. A current list of backflow assemblies approved for installation in Washington State is also kept in the program's files. Both of these lists are updated on a regular basis. Element 7: The purveyor shall develop and implement (when appropriate) procedures for responding to backflow incidents. This element is covered in the City of Renton Water System Emergency Response Plan and also in the Security‐ Terrorism Appendix. Each backflow incident is investigated by the City upon its discovery or knowledge. Reports of investigations and findings are sent to the Washington State Department of Health for each actual backflow incident. The City Public Works staff has been trained on response to various emergencies including a contamination of the water distribution system through cross connections. Element 8: The purveyor shall include information on Cross Connection Control in the purveyor's existing program for educating customers about water distribution system operation. The public education program may include periodic bill inserts, public service announcements, pamphlet distribution, notification of new consumers, and consumer confidence reports. The City provides information on cross connection through its website and the annual Water Quality Report (also known as the Consumer Confidence Report). Public outreach and education are conducted through special events, such as Renton River Days and through regional participation with other water purveyors. Element 9: The purveyor shall develop and maintain Cross Connection Control records including, but not limited to, the following: i. A master list of service connections and/or customer’s premises where the purveyor relies upon Washington State approved backflow assemblies to protect the public water distribution system from contamination, the assessed hazard level of each, and the required backflow assembly/assemblies; ii. Inventory information on backflow assemblies that protect the public water system including: A. Approved Air Gaps installed in lieu of approved backflow assemblies including exact Air Gap location, assessed degree of hazard, installation date, history of inspections, inspection results, and person conducting inspections; B. Approved backflow assemblies including exact assembly location, assembly description (type, manufacturer, model, size, and serial number), assessed degree of hazard, installation date, history of inspections, tests and repairs, test results, and person performing tests; and C. Approved Atmospheric Vacuum Breakers (AVB) used for irrigation system applications including location, description (manufacturer, model, and size), installation date, history of inspection(s), and person performing inspection(s). iii. Cross Connection Control Program summary reports and backflow incident reports required under [WAC 246‐290‐490(8)]. The City’s Cross Connection Control Program currently uses XC2 software and track the following information on each backflow assembly and facility served with City water: level of hazard, type of backflow assembly used, premise or in‐premise use, location of assembly or Air Gap, installation date, inspection history, test and repair history, test results, tester’s information, and inspection of assembly. The City keeps records of all backflow incident investigations and Annual Summary Reports. Element 10: Purveyors who distribute and/or have facilities that receive reclaimed water within their water service area shall meet any additional Cross Connection Control requirements imposed by the department in a permit issued under chapter 90.46 RCW. The King County Wastewater Treatment Plant uses reclaimed water produced by the plant. There is an approved Air Gap between the City’s water supply and the domestic water tank owned by King County. The Boeing Customer Training Center has a support facility that uses reclaimed water for its cooling system, and there is an approved DCVA at the City’s domestic meter to the facility and a RPBA at the service branch to the cooling system.

INTRODUCTION Providing safe, clean drinking water is one of Renton’s highest priorities. Our municipal water system produces an average of 7.3 million gallons of water each day and serves over 98,000 customers. To ensure public health protection, the City of Renton (City) has established a monitoring program that covers operational parameters, regulatory requirements, and aquifer protection. This Plan supplements the City’s 2019 Water System Plan and updates the 2012 Drinking Water Quality Monitoring Plan. The document is divided into five sections. The first section describes the water system and treatment process for each source. The second section describes water quality monitoring for operations. The third section describes water quality compliance monitoring per state and federal regulations, such as Chapter 246-290 of the Washington Administrative Code (WAC) and the Safe Drinking Water Act. The fourth section describes aquifer management monitoring, which is part of the City’s Aquifer Protection Program. The fifth section discusses current drinking water regulations that have a significant impact on water utility operations. The City’s Coliform Monitoring Manual and Stage 2 Disinfectants and Disinfection Byproducts Monitoring Plan are presented in Appendix A and B, respectively. II. WATER SYSTEM OVERVIEW The City’s water system provides service to an area of approximately 17.25 square miles that is largely coincident with the city limits. The water distribution system serves the valley floor and parts of five surrounding hills: West Hill, the Highlands, Scenic Hill (also known as Renton Hill), Talbot Hill, and Rolling Hills. The City currently serves 17,830 customers (service connections) within an elevation range of 11 to 475 feet. The City supplies wholesale water to Skyway Water and Sewer District through a single-metered connection. The City owns and operates a multi-source municipal water system including supply, treatment, storage, and distribution of potable water to residential, commercial, industrial, and wholesale customers. The City’s water distribution system consists of more than 300 miles of pipeline. Water supply sources include five downtown wells (RW-1, RW-2, RW-3, PW-8, and PW-9) and one artesian spring (Springbrook Springs) that are used for normal supply. The production wells draw from a relatively shallow aquifer (Cedar Valley Aquifer), which is an underground layer of sand and gravel that runs 3 1/2 miles long and at some points is only 23 feet below ground surface. The aquifer is fed by rain and snow falling on the aquifer and higher adjacent ground, as well as by groundwater flow from the Cedar Valley. As the City's primary water source, the Cedar Valley Aquifer has been designated a "sole source" by the U.S. Environmental Protection Agency. There are also three production wells (PW-11, PW-12, and PW-17) located east of the downtown area at the Maplewood Golf Course that provide an alternate source of supply in the event of the contamination of the Downtown Wellfield. A secondary purpose of the Maplewood Wellfield is to provide supplementary (non-additive) supply during high demand periods. In addition, the City is a wholesale customer of SPU, which gets its supply from the Cedar and Tolt Rivers. The City currently only buys wholesale water from SPU to sell directly to Boeing, but the City has a long-term supply contract for backup supply during summer peak use periods and for future water demands. As a result of the City’s topography and geography, the City has 16 hydraulically distinct pressure zones. Pumping throughout the water system is accomplished by 12 booster pump stations (BPS) that are located throughout the City. Currently there are 10 reservoirs in the system, strategically located to provide adequate equalizing and fire flow reserves for all pressure zones. Pressure reducing valves (PRVs) are used to supply lower pressure zones from higher pressure zones that contain water storage reservoirs. The City has seven metered interties with the SPU transmission mains and three additional emergency supply interties with other neighboring water systems. Each source is currently designed with primary disinfection using chlorine (gaseous chlorine or sodium hypochlorite). Sodium fluoride is also added at each source to prevent dental caries. The City treats the water from the Downtown Wells and Springbrook Springs with sodium hydroxide (NaOH) to raise the pH of the water, which decreases the corrosivity of the water. The Maplewood Treatment Plant treats water by: (1) removes hydrogen sulfide by converting it to sulfate by adding oxygen (granular activated carbon is used as a catalyst), (2) removes manganese using green sand filters, and (3) converts ammonia in the water to nitrogen gas by reacting it with sodium hypochlorite in a contact basin. A corrosion inhibitor and sequestering agent is used in Well PW-5A to treat for naturally-occurring iron and manganese. Since there is also naturally-occurring ammonia in the water, the chlorine dosage is set to create monochloramines for disinfection. With existing treatment, aesthetic-related problems (taste, odor, and staining) still remain; therefore this source is only used as a back-up source of supply at this time. The City also adds Aqua Mag® blended phosphates to the water in areas of the distribution system that contain a high number of unlined cast iron water mains. It acts to control the corrosion of the interior surfaces of water mains. Ortho-polyphosphates are added at the Mt. Olivet BPS and West Hill BPS. III. MONITORING FOR OPERATIONS Operational monitoring is used to check that treatment plants and other water facilities are operating effectively to deliver water that meets standards and to provide early warning that source water quality may be deteriorating or a treatment process may be failing. Operational monitoring samples are analyzed in laboratories located in the City’s treatment plants, as approved by WAC 246-290-300(1)(c). A. Chlorine Parameters: Free chlorine residuals are measured in milligrams per liter (mg/L). Chlorine demand is calculated in mg/L. The City maintains a free chlorine residual between 0.6 and 1 mg/L throughout the distribution system. Sampling and Analysis Methods: The City continuously measures the free chlorine residual in the treated water from each source using fixed in-line Hach CL17 analyzers (colorimetric DPD analysis, EPA Method 334.0). The analyzer data is recorded by supervisory control and data acquisition (SCADA) and the results are stored in the SCADA System History database. Water quality maintenance staff also measure for free chlorine residuals on a daily basis from each source that is operating when staff is present and at nine sampling stations located throughout the distribution system. Each grab sample is manually collected in a glass bottle and analyzed using a Chlorine Reagent with a portable Hach Pocket Colorimeter II (Hach Method 8021). Per regulatory requirements, water quality maintenance staff measure for free chlorine residuals during compliance total coliform bacteria (Bac-T) sampling (see the Coliform Monitoring Plan in Appendix A for the locations of the coliform sampling sites).

Data from this field form is used to complete the forms sent to DOH. Chlorine demand is calculated based on volume of water produced and pounds of chlorine consumed. The combined chlorine demand is calculated daily for all the chlorine gas supplied sources (Springbrook Springs; RW-1, 2 & 3; PW-8 & 9; and EW-3R) and for the sodium hypochlorite supplied sources (PW-11, 12 & 17). Each calculated value is recorded on the DOH form, Chlorination Plant & Turbidity Report, which is sent to DOH on a monthly basis. The number of samples, the highest concentration, the lowest concentration, and the average concentration of free chlorine are also recorded daily on the DOH form per each chlorine type (combined chlorine gas supplied sources and combined sodium hypochlorite supplied sources). The chlorine residual concentration at each operating source is recorded daily on the DOH form, Ground Water Treatment Plant Report, which is sent to DOH on a monthly basis. Copies of these DOH reports are provided to water utility engineering staff. The free chlorine residual concentrations, which are measured during Bac-T sample collection, are recorded on the coliform sample report forms that are submitted to the commercial laboratory for compliance purposes 1. 1 Sources: WAC 246-290-300(3)(a)(ii) B. Fluoride Parameters: Fluoride is measured in mg/L. Fluoride demand is calculated in mg/L. The City maintains a fluoride concentration of 0.7 mg/L with an operating tolerance of 0.5 and 0.9 mg/L. Sampling and Analysis Methods: Water quality maintenance staff measure for fluoride on a daily basis from each source that is operating when staff is present and at three sampling stations located throughout the distribution system. Each grab sample is manually collected in a plastic bottle and analyzed at the City Shops laboratory by the SPADNS 2 colorimetric method (Hach Method 10225) using a Fluoride Reagent with a Hach DR2700 Spectrophotometer. Once a month, the water quality maintenance staff collect two fluoride grab samples at every source that was operational during that month. One sample is tested at the City Shops laboratory using the City- owned testing equipment (see above). The result of the test along with the second sample are sent to a commercial laboratory for analyses (see Inorganic Chemical and Physical for fluoride compliance monitoring). Both results are submitted to the DOH for comparison to ensure proper calibration of the City’s testing equipment.

Data from this field form is used to complete the forms sent to DOH. Fluoride demand is calculated based on volume of water produced and pounds of sodium fluoride consumed. Daily fluoride concentrations and fluoride demand for each operational source are recorded on the DOH form, Fluoridation Monthly Operations Report, which is sent to DOH on a monthly basis. The fluoride concentrations that are measured daily at each operational source are also reported on the DOH form, Ground Water Treatment Plant Report, which is sent to DOH on a monthly basis. Copies of the DOH reports are provided to water utility engineering staff. C. Turbidity Parameters: Turbidity is measured in Nephelometric Turbidity Units (NTUs). Sampling and Analysis Method: Water quality maintenance staff measure for turbidity on a daily basis from each source that is operating when staff is present. Turbidity is measured at the source, before treatment (raw sample). Each grab sample is manually collected in a plastic bottle and analyzed at the Corrosion Control Treatment Facility laboratory using a Hach 2100N Turbidimeter (EPA Method 180.1).

Data from this field form is used to complete the forms sent to DOH. The daily high value and low value for turbidity are recorded on the DOH form, Chlorination Plant & Turbidity Report, per each chlorine type (combined chlorine gas supplied sources and combined sodium hypochlorite supplied sources). These reports are sent to DOH on a monthly basis, and copies are provided to water utility engineering staff. D. Temperature Parameters: Temperature is measured in degrees Celsius. Sampling and Analysis Method: Water quality maintenance staff measure for temperature on a daily basis from each source that is operating when staff is present. Temperature is measured at the source, before treatment with chlorine and fluoride (raw water sample). Grab Sample Locations: See Turbidity Grab Sample Locations. Recording and Reporting: Water quality maintenance staff record the temperature measurements on the field form, City of Renton Pump/Chemical Feed/Sampling Stations. Data from this field form is used to complete the forms sent to DOH. The daily temperature for each operational source is transferred onto the DOH form, Ground Water Treatment Plant Report, which is sent to DOH on a monthly basis. Copies of the DOH reports are provided to water utility engineering staff. E. Phosphate Parameters: Phosphate (PO43-) is measured in mg/L. The City monitors for phosphate because ortho- polyphosphates are added into the distribution system where there is a potential for corrosion of iron pipes. The optimal range for ortho-polyphosphates is between 1.0 to 2.0 mg/L. Sampling and Analysis Method: Water quality maintenance staff measure for phosphate on a daily basis at two sampling stations located in areas of the distribution system that contain a high concentration of unlined cast iron water mains. Each grab sample is manually collected in a plastic bottle and analyzed at the City Shops laboratory by the colorimetric method (Hach Method 8048) using a Phosphate Reagent with a Hach DR2700 Spectrophotometer. Grab Sample Locations: Sampling Station Name Water Quality Database ID 2510 Meadow Av N Sampling Station MS033 Lind NW & Taylor Pl NW Sampling Station MS032 Recording and Reporting: Water quality maintenance staff record the phosphate concentrations on the field form, City of Renton Pump/Chemical Feed/Sampling Stations. The results are transferred onto the City form, Iron and Phosphate, which is provided to water utility engineering staff. F. Iron Parameters: Iron (Fe) is measured in mg/L. The City monitors for iron in areas of the distribution system where there is a potential for corrosion of iron pipes and at the Maplewood sources containing naturally- occurring iron. Iron concentrations of 0.3 mg/L or greater can cause a metallic taste in the water and reddish brown staining of laundry and plumbing fixtures for customers. To eliminate staining problems, the City has a treatment goal of 0.05 mg/L or less for iron concentrations in the treated water. Sampling and Analysis Method: Water quality maintenance staff measure for iron on a daily basis at two sampling stations located in areas of the distribution system that contain a high concentration of unlined cast iron water mains. Grab samples are manually collected in a plastic bottle and analyzed at the City Shops laboratory by the colorimetric method (Hach Method 8008) using an Iron Reagent with a Hach DR2700 Spectrophotometer. When the Maplewood sources are operational (and if time allows), water quality maintenance staff also measure for iron at the Maplewood Treatment Plant. Iron is measured at the raw water intake, mid- point of the Chlorine Contact Chamber, and at the low-lift pump discharge pipe (when running). Each grab sample is manually collected in a plastic bottle and analyzed at the Maplewood Treatment Plant by the colorimetric method (Hach Method 8146) using an Iron Reagent with a Hach DR3900 Spectrophotometer.

The results are transferred onto the City form, Iron and Phosphate, which is provided to water utility engineering staff. Results from the Maplewood Treatment Plant are recorded on the City form, Maplewood Treatment Plant Operations Log. G. Manganese Parameters: Manganese (Mn) is measured in mg/L. The City monitors for manganese, which occurs naturally in the deep Maplewood Aquifer. Manganese concentrations of 0.05 mg/L or greater can cause a metallic taste in the water and brownish black staining of laundry and plumbing fixtures for customers. To eliminate staining problems, the City has a treatment goal of 0.01 mg/L or less for manganese concentrations in the treated water at the Maplewood Treatment Plant. Sampling and Analysis Method: When the Maplewood sources are operational (and if time allows), water quality maintenance staff measure for manganese at the Maplewood Treatment Plant. Manganese is measured at the raw water intake, mid-point of the Chlorine Contact Chamber, and at the low-lift pump discharge pipe (when running). Each grab sample is manually collected in a plastic bottle and analyzed at the Maplewood Treatment Plant by the PAN colorimetric method (Hach Method 8149) using a Manganese Reagent Set with a Hach DR3900 Spectrophotometer.

H. Ammonia Parameters: Ammonia (NH3-N) is measured in mg/L. At the Maplewood Treatment Plant, breakpoint chlorination is used to remove naturally-occurring ammonia. Sampling and Analysis Method: When the Maplewood sources are operational (and if time allows), water quality maintenance staff measure for ammonia at the Maplewood Treatment Plant. Ammonia is measured at the raw water intake and at the mid-point of the Chlorine Contact Chamber. Each grab sample is manually collected in a plastic bottle and analyzed at the Maplewood Treatment Plant by the Salicylate colorimetric method (Hach Method 10023) using an Ammonia Salicylate Reagent with a Hach DR3900 Spectrophotometer. Grab Sample Locations: Sampling Station Name Water Quality Database ID Wells PW-11-12-17 Raw Water SA#4 PS016 Maplewood Chlorine Contact Chamber SA#11 PS023 Recording and Reporting: Results are recorded on the City form, Maplewood Treatment Plant Operations Log. I. Hydrogen Sulfide Parameters: Hydrogen Sulfide (H2S) is measured in mg/L. At the Maplewood Treatment Plant, granular activated carbon is used to convert naturally-occurring hydrogen sulfide to sulfate. To improve taste and odor, the City has a treatment goal of 0.001 mg/L or less for hydrogen sulfide concentrations in the treated water. Sampling and Analysis Method: When the Maplewood sources are operational (and if time allows), water quality maintenance staff measure for hydrogen sulfide at the Maplewood Treatment Plant. Hydrogen sulfide is measured at the raw water intake and at the mid-point of the Chlorine Contact Chamber. Each grab sample is manually collected in a plastic bottle and analyzed at the Maplewood Treatment Plant by the Methylene Blue colorimetric method (Hach Method 8131) using Sulfide Reagents with a Hach DR3900 Spectrophotometer.

J. pH Parameters: pH is measured on a scale of 0 to 14, with 7 being neutral. pH values less than 7 indicate acidic conditions, which can lead to corrosion and the leaching of metals. As recommended by the DOH, the optimal pH range for the City’s treated water is between 7.2 and 10. Sampling and Analysis Method: The City measures the pH of treated water continuously by analyzer at all sources. The analyzer data is recorded by SCADA and the results are stored in the SCADA System History database. Water quality maintenance staff also measure for pH on a daily basis at sources operating when they are present (both before and after NaOH injection) and at two sampling stations located throughout the distribution system. Samples are manually collected in a plastic bottle and analyzed at the Corrosion Control Treatment Facility laboratory using a Thermo Electron Corp pH meter.

The measurements are transferred to the City form, pH, which is provided to water utility engineering staff. Data from this field form is also used to complete the forms sent to DOH. Pre- and post-treatment pH values for each operational source are transferred onto the DOH form, Ground Water Treatment Plant Report, which is sent to DOH on a monthly basis. Copies of the DOH reports are provided to water utility engineering staff. K. Well Water Levels Parameters: Water levels are measured in feet, from the top of the well casing (TOC). Sampling and Analysis Method: Well transducers measure the water level continuously in each production well. The transducer data is recorded by SCADA and the results are stored in the SCADA System History database. Water quality maintenance staff also manually measure the water level at each production well with the exception of Well PW-12. Well PW-12 requires confined space entry. Manual measurements are performed on a monthly basis, whether the well is in operation or not. Locations: Wells RW-1, RW-2, RW-3, PW-8, PW-9, EW-3R, PW-11, and PW-17. Recording and Reporting: Water quality maintenance staff record the water levels on the field form, City of Renton Pump/Chemical Feed/Sampling Stations. The measurements are transferred to the City form, Well Level Measurements YYYY, which is provided to water utility engineering staff. Water utility engineering staff enter the measurements into the City’s Water Level database, which stores historical data for the City’s production wells and groundwater monitoring (non-pumping) wells. L. Production Volumes and Flow Rates Parameters: The volume of water produced is measured in gallons, and the flow rate is calculated in gallons per day. Sampling and Analysis Method: Flow meters measure the flow rate continuously at each metered location. The flow data is recorded by SCADA and the results are stored in the SCADA System History database. Water quality maintenance staff also manually record flow meter readings on a daily basis for each source. Locations: Each source and each BPS with the exception of Tiffany Park and Fred Nelson. Recording and Reporting: Water quality maintenance staff record the flow meter readings on the field form, City of Renton Pump/Chemical Feed/Sampling Stations. The total monthly production volume and average daily flow rate at each location are calculated and recorded on the City form, Renton Water Utility Monthly Report, which is provided to water utility engineering staff. IV. COMPLIANCE MONITORING Compliance monitoring is used to determine whether water supplies comply with standards and indicator parameters in state and federal regulations. This monitoring is mandatory and compliance monitoring samples are analyzed using EPA-approved methods at State-certified laboratories, with the exception of residual disinfectant concentration. The State of Washington has primacy over the regulation of public drinking water. This means the DOH has full authority and responsibility for implementing and enforcing both state and federal drinking water laws. Under primacy, the DOH must adopt state rules that are at least as stringent as the rules promulgated by the EPA. Regulatory requirements in this section are referenced to WAC 246-290, unless the WAC directly references the Code of Federal Regulations (CFR) or a federal drinking water law has yet to be included in the WAC. Adjustments to the monitoring frequency may be granted by the DOH if there is low vulnerability to contamination from a certain chemical or group of chemicals. The DOH has the authority to grant waivers for certain parameters, depending on vulnerability and previous sampling results. The DOH has issued state-wide waivers for insecticides, dioxin, diquat, endothall, glyphosate, polychlorinated biphenyls (PCBs), ethylene dibromide (EDB), and dibromochloropropane (DBCP). The City also has a permanent waiver for asbestos; temporary waivers for inorganic contaminants (IOCs), volatile organic chemicals (VOCs), and synthetic organic chemicals (SOCs); and a reduced monitoring schedule for total trihalomethane (TTHM) and haloacetic acids (HAA5). A. Bacteriological Regulatory Requirement: Monitoring for total coliforms and Escherichia coli (E.coli) is required per state and federal regulations 2. Systems need only determine the presence or absence of total coliforms and E.coli 3. Coliform treatment technique triggers, assessment requirements, and violations are specified in WAC 246-290-320(2) and described in the Coliform Monitoring Plan in Appendix A. Sampling Locations and Frequency: 100 routine samples are required each month. See coliform sampling site locations in the Coliform Monitoring Plan in Appendix A. Sampling and Analysis Method: Water samples for bacteriological analysis are collected in plastic bottles provided by the commercial laboratory and placed in a chilled cooler. The samples are tested by a State- accredited laboratory using EPA Methods specified in 40 CFR 124.21(f). Recording and Reporting: The commercial laboratory reports results directly to DOH. A copy of the sample report form is returned to water quality maintenance staff with a “present” or “absent” indication for coliform bacteria. 2 Sources: WAC 246-290-300(3), 40 CFR 141.21 & Subpart Y 3 Sources: WAC 246-290-310(2), 40 CFR 141.852(a)(2) B.

The samples are tested by a State-accredited laboratory using EPA Methods specified in 40 CFR 124.23(k). Sampling Frequency: Nitrate must be sampled annually (there is no waiver for nitrate). Other IOCs are sampled once per every 3 years, unless waived by DOH7. The City currently has waivers to reduce monitoring for IOC to once per every 9 years. Recording and Reporting: The commercial laboratory reports results directly to DOH and sends a copy to the water quality maintenance staff. A copy of the laboratory report is also provided to water utility engineering staff, who enters the analytical results into the City’s Water Quality database. C. Residential Tap Sampling for Lead and Copper Regulatory Requirement: Monitoring at residential taps for lead and copper is required per state and federal regulations 8. The action levels for lead and copper are 0.015 and 1.3 mg/L, respectively 9. As part of the lead and copper tap sampling program, the City also collects pH samples within the distribution system. The optimal water quality parameter requirement is pH greater than or equal to 7.2 in the distribution system. Sampling Locations: The City is required to sample 30 sites (single-family homes)10 for lead and copper. There are 159 qualified sites in the City’s Water Quality database (identified by the designation “LS***”). The City is also required to sample for pH at seven locations within the distribution system. The pH levels are collected from dedicated sampling stations used for routine coliform samples. 6 Sources: WAC 246-290-300 (Table 4), 40 CFR 124.23(a)(1) 7 Sources: WAC 246-290-300(4), 40 CFR 141.23(b-e) 8 Sources: WAC 246-290-300(5), 40 CFR 141.86-88 9 Sources: WAC 246-290-310(Table 5), 40 CFR 141.80(c) 10 Sources: WAC 246-290-300(5), 40 CFR 141.86(c)&(d)(4)(v) Sampling and Analysis Method: Lead and copper samples are collected by residents from the cold water side of their kitchen or bathroom faucets. The samples are collected in plastic bottles provided by the commercial laboratory. Residents are instructed not to run the water for 6 hours prior to taking the sample. Water utility engineering staff collect the filled bottles and deliver the samples to the commercial laboratory for analysis. The pH levels are field measured using a Hach Pocket Pro+ pH meter. Sampling Frequency: Once per every 3 years11 for lead and copper. Lead and copper samples must be collected between June 1 and September 30. The pH samples must be collected twice every 3 years. Recording and Reporting: The commercial laboratory reports lead and copper compliance results directly to DOH and sends a copy to the water quality engineering staff who manage the lead and copper tap sampling program. The analytical results are entered into the City’s Water Quality database and letters are distributed to participants with the results. D. Disinfectant Residuals and Disinfection Byproducts Regulatory Requirement: Monitoring for disinfectant residuals (chlorine) and disinfection byproducts (TTHM and HAA5) is required per state and federal regulations 12. The MCLs for TTHM and HAA5 are 0.080 and 0.060 mg/L, respectively13. The maximum residual disinfectant level (MRDL) for chlorine is 4 mg/L (as Cl2)14. As of January 2017, the DOH requires a detectable residual disinfectant concentration of at least 0.2 mg/L in all active parts of the distribution system 15. In order to maintain the chlorination requirements of 4-log virus treatment (CT=6), the City has minimum chlorine residuals required at the end of each CT pipeline: • Springbrook Springs = 0.80 mg/L • Wells RW-1, RW-2, and RW-3 = 0.62 mg/L • Wells PW-8 and PW-9 = 0.70 mg/L • Well EW-3R = 0.85 mg/L At the Maplewood Treatment Plant, water in the Chlorine Contact Basin and Clearwell have a contact time of at least 4 hours before the treated water enters the distribution system. The City maintains a chlorine residual of 1.0 mg/L for the Maplewood Wellfield. Distribution monitoring for TTHM and HAA5 are covered by DOH TEST PANELS: TTHM and HAA5. Source water monitoring for TTHM is covered by DOH TEST PANEL: VOC1. Sampling Locations and Frequency: Water quality maintenance staff measure for chlorine residuals on a daily basis from each source that is operating when staff is present and at nine sampling stations located throughout the distribution system (see chlorine sampling locations in Section III - Monitoring for Operations). Water quality maintenance staff also measure for chlorine residuals at coliform sampling stations during compliance Bac-T sampling (see the Coliform Monitoring Plan in Appendix A). 11 Sources: WAC 246-290-300(5), 40 CFR 141.86(d)(4)(v) 12 Sources: WAC 246-290-300(2),(3)&(6), 246-290-451, 40 CFR 141 Subpart V 13 Sources: WAC 246-290-310(4)(b), 40 CFR 141.64 14 Sources: WAC 246-290-310(5)(b), 40 CFR 141.65 15 Sources: WAC 246-290-010(80), 246-290-451(7)(b) The City is currently on a reduced monitoring schedule for TTHM and HAA5.

Aquifer Management Monitoring Groundwater systems undergo short-term and long-term changes in climate, withdrawal, and land use that can affect groundwater recharge and storage. Water level measurements from monitoring (non-pumping) wells allow the City to study how these stresses affect the supplying aquifers 28. Water quality monitoring provides an early warning that contaminants may be near the City’s production wells. A long-term record of water levels and water quality data allows the City to refine its groundwater model, forecast trends, track climate events, and assist future planning decisions. A. Aquifer Water Quality Monitoring Goal: To provide an early warning of contaminants present in the capture zones of the City’s production wells. Program Status: Water utility engineering staff conduct semi-annual groundwater sampling using a network of monitoring wells (different from the City’s production wells). In March and September, six monitoring wells are sampled for VOCs. If contaminants are detected, water utility engineering will immediately notify the water quality maintenance supervisor and follow-up sampling will occur. The groundwater samples are analyzed by a commercial laboratory. A copy of the laboratory report is provided to water utility engineering staff, who enters the analytical results into the City’s Water Quality database. Sampling Locations: March Sampling Event September Sampling Event MW-31S, 31D, 25S, 25D, 4, 34S MW-42, 26R, 3, 5, 33, OBW-1S B. Downtown Aquifer Water Levels Goal: To track short-term (seasonal) and long-term changes in the water table elevation of the downtown aquifer (Cedar Valley Aquifer). Program Status: Water utility engineering staff measure water levels from 18 monitoring wells located throughout downtown Renton on a monthly basis. Measurements are taken from a marked and surveyed measuring point on each well, with a precision of 0.01 foot. Water utility engineering staff enter the water level measurements into the City’s Water Level database, which stores historical data for the City’s production wells and groundwater monitoring wells. Monitoring Locations: Monitoring Wells MW-1, MW-5, MW-10, MW-11, MW-18, MW-20, MW-21, MW- 25S & D, MW-26R, MW-27, MW-30S & D, MW-31S & D, MW-33, and MW-34S & D. 28 Sources: Taylor, C. J. and Alley, W. M. (2001). Ground-water-level monitoring and the importance of long-term water-level data. US Geological Survey Circular, 1217. C. Maplewood Aquifer Water Levels Goal: To track short-term (seasonal) and long-term changes in the water table elevation of the Maplewood Aquifer and to analyze the effects of production well pumping. Program Status: Water utility engineering staff maintain data recorders (Solinst Leveloggers) in six groundwater monitoring wells located at the Maplewood Golf Course. A barometric data recorder (Solinst Barologger) is also kept at the golf course so that the recorded barometric information can be used to remove the effects of barometric pressure. The data recorders measure pressure and temperature and are programmed to take measurements every 15 minutes. The data is periodically downloaded from the transducers. Monitoring Locations: MW-36S & D, MW-37S & D, and OBW-1S & D. VI. WATER QUALITY REGULATIONS OF CURRENT SIGNIFICANCE The City complies with state and federal regulations to ensure the system’s drinking water is safe and reliable. Since the previous Water System Plan Update, the EPA issued one new drinking water rule and revised one existing drinking water rule. The City’s monitoring requirements also changed for two existing drinking water rules. The water quality regulations of current significance to the City are summarized below. A. Revised Total Coliform Rule (RTCR) The RTCR is the revision to the 1989 Total Coliform Rule (TCR) and is intended to improve public health protection through the reduction of potential pathways of entry for fecal contamination into the distribution system. EPA published the RTCR in the Federal Register in 2013 (minor corrections in 2014), and the rule became effective on April 1, 2016. The RTCR applies to all public water systems (PWSs). The RTCR establishes a MCL for E.coli and requires each total coliform-positive routine sample to be tested for the presence of E.coli. The system must also collect three repeat samples for every unsatisfactory routine sample. See the Coliform Monitoring Plan in Appendix A for a detailed description of MCL and treatment technique violations. Public notification is required after drinking water violations. The public notices are issued depending on the tier to which the violation is assigned (Tier 1 - Immediate Notice, Tier 2 - Within 30 days, and Tier 3 - Annual Notice). The RTCR also requires the system to conduct an assessment to find and correct any sanitary defects after a treatment technique trigger occurs. There are two levels of assessment (Level 1 and Level 2) based on the severity or frequency of the problem. The assessment must be completed within 30 days after the trigger occurs. City of Renton Action: Historical bacteriological water quality violations led the City to take steps to greatly improve its response to bacterial contamination in its water supply, and improve its communications with the DOH and analytical laboratory. The City developed a comprehensive Coliform Monitoring Manual (Appendix A) which includes the required Coliform Monitoring Plan; an additional 1-page Reference Guide that concisely summarizes how water quality maintenance staff should respond when a sample tests positive for coliform bacteria; an Emergency Phone List with contact information for water quality maintenance staff, analytical laboratories, and regulatory agencies; and a Self-Assessment Guidance Document that would be completed by water quality maintenance staff during coliform detections to help identify and correct any sanitary defects. The City also upgraded its infrastructure to provide primary disinfection (4-log virus treatment) at every source. The Downtown Wells are equipped with chlorine contact systems (CT=6 pipelines) installed in Liberty Park and Cedar River Park. At Maplewood, water in the Chlorine Contact Basin and Clearwell has a contact time of at least 4 hours before entering the distribution system. Each source is also equipped with monitoring equipment that measures the chlorine concentration continuously and automatic shut- off if the required minimum chlorine residual is not maintained. Water quality maintenance staff perform coliform monitoring weekly at 27 sampling sites. The Coliform Monitoring Plan in Appendix A identifies the routine sampling sites. The City has been well within the regulatory requirement of less than 5 percent of samples with detectable total coliform for its distribution system. Over the past 6 years, the City has collected approximately 7,000 coliform samples and only 2 have been positive for total coliform (both in 2019) and no samples have been positive for E.coli. Follow-up sampling in 2019 showed no indication of contamination, and public notification was not required. B. The Ground Water Rule (GWR) The GWR builds on the Total Coliform Rule by addressing the health risks of fecal contamination in community PWSs that use groundwater sources. The EPA published the rule in the Federal Register in 2007, and the DOH adopted the rule in 2010. The GWR applies to all Group A community PWSs that: • Rely entirely on one or more groundwater sources; • Receive finished groundwater from another PWS; or • Operate a mixed system (surface water and groundwater). The rule’s targeted, risk-based approach relies on four major components: • Periodic sanitary surveys of systems that require the evaluation of eight critical elements of a PWS and the identification of significant deficiencies (e.g., improperly constructed well, unprotected cross-connections, or improper recordkeeping); • Triggered source water monitoring when a system identifies a positive sample during its routine coliform monitoring or assessment monitoring targeted at high-risk systems; • Corrective action is required for any system with a significant deficiency or source water fecal contamination; and • Compliance monitoring to ensure that treatment technology installed to treat drinking water reliably achieves 99.99 percent inactivation of viruses (4-log treatment). City of Renton Action: The City continuously monitors the chlorine concentration at each source and also maintains DOH- specified minimum chlorine residual concentrations (see disinfectant residuals and disinfectant byproducts in Section IV – Compliance Monitoring). The City also conducts sanitary surveys once every 5 years to identify any significant deficiencies. The last sanitary survey was completed on March 31, 2017. Water quality maintenance staff collect source water (raw) samples at the same time they collect routine coliform samples (RTCR compliance monitoring). This allows the City to immediately determine if E.coli is present. These source water samples count as triggered source water samples. If an E.coli-positive sample is detected in a source water sample, the DOH will direct the City to either take corrective action or take five additional source samples within 24 hours. If E. coli continues to be present in source water samples, the DOH will direct the City to take corrective action and issue public notification. The Coliform Monitoring Manual in Appendix A identifies public notification requirements. C. Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts Rules (D/DBPR) The purpose of the Stage 1 and Stage 2 D/DBPR is to improve public health protection by reducing the potential risk of adverse health effects associated with disinfectants and disinfection byproducts in the distribution system. The Stage 1 D/DBPR regulates MCL compliance for disinfectants and disinfection byproducts. Stage 2 builds upon Stage 1 by focusing on monitoring and reducing concentrations of two classes of disinfection byproducts (TTHM and HAA5)29. EPA published the Stage 1 and Stage 2 D/DBPR in the Federal Register in 1998 and 2006, respectively, and DOH adopted the rules in 2003 and 2010. Note that the Stage 2 D/DBPR is an extension of the Stage 1 D/DBPR so systems must continue to comply with the requirements of the Stage 1 D/DBPR in addition to meeting the requirements of the Stage 2 D/DBPR. Overview of Current Monitoring Requirements • Each water system must conduct an initial system evaluation or qualify for an evaluation waiver. • Community PWSs must monitor if any water they provide is treated with chlorine disinfection. • The number of samples served is based on population served and source water type. • Sample locations are based on locations of highest TTHM and HAA5 averages. • Use a locational running annual average (LRAA) calculation to determine MCL compliance for TTHM and HAA5 (Note: the MCL values are the same as the Stage 1 MCLs; only the calculation method changed for Stage 2). • Continue to comply with MRDLs for chlorine or chloramine. Initial Distribution System Evaluation (IDSE) The Stage 2 D/DBPR requires PWSs to complete an initial evaluation to characterize disinfection byproduct concentrations in their distribution systems and identify locations to monitor for TTHM and HAA5 compliance30. The Stage 2 D/DBPR requires TTHM and HAA5 compliance on the LRAA calculated at each monitoring location. The IDSE options for the City are: Standard Monitoring, System Specific Study, and 40/30 Certification (no IDSE monitoring requirements). To be eligible for a 40/30 Certification, the PWS must meet all of the following requirements for eight consecutive quarters of monitoring: • Collected all required Stage 1 D/DBPR samples; • No individual TTHM samples exceeded 0.040 mg/L and HAA5 samples exceeded 0.030 mg/L; and • The system has not had any TTHM or HAA5 monitoring violations 31. City of Renton Action: The City chlorinates its drinking water to kill or inactivate harmful microorganisms. The City received a 40/30 Certification in 2007 and therefore was not required to complete an IDSE. Based on the current TTHM and HAA5 concentrations in the distribution system, the City is eligible for reduced monitoring. Water quality engineering staff perform TTHM and HAA5 compliance monitoring once a year at two sampling sites in the distribution system. See the Stage 2 Disinfectants and Disinfection Byproducts Monitoring Plan in Appendix B for more information. 29 Sources: WAC 246-290-300(6)(b)(i)(A), 40 CFR 141 Subpart V 30 Sources: WAC 246-290-300(6)(b)(i)(F), 40 CFR 141 Subpart U 31 Sources: 40 CFR 141.603 D. Unregulated Contaminants Monitoring Rule 4 (UCMR4) The SDWA establishes periodic monitoring of chemicals and microbes that are suspected to be in drinking water, but not currently subject to drinking water regulations 32. The unregulated contaminants are selected from the contaminant candidate list for potential regulatory consideration. The EPA published UCMR4 in the Federal Register in 2016, and it is the fourth cycle of UCMR monitoring. Under UCMR4, large water systems conduct sampling for Assessment Monitoring "List 1" contaminants: 10 cyanotoxins (surface-water systems only) and 20 additional contaminants (2 metals, 8 pesticides plus 1 pesticide manufacturing byproduct, 3 brominated HAA groups, 3 alcohols, and 3 other semivolatiles). The monitoring period for UCMR4 is 2018 through 2020. For groundwater systems, sampling is conducted twice in a continuous 12-month period with the sampling events to occur five to seven months apart. Sample collection takes place at every entry point to the distribution system or at representative sampling locations with approval from the EPA. If any unregulated contaminants are detected, the results are required to be reported in the Consumer Confidence Report 33 (CCR). City of Renton Action: In 2017, the Water Utility submitted a Proposed UCMR4 Groundwater Representative Monitoring Plan (GWRMP) to the EPA. The Water Utility proposed three representative groundwater sample locations for UCMR4 sampling. The EPA approved the GWRMP on January 11, 2018. The City performed UMCR4 sampling in October 2018 and April 2019. The City was required to sample for the following contaminants: • Two metals: germanium and manganese. • Eight pesticides and one pesticide manufacturing byproduct: alpha-hexachlorocyclohexane, profenofos, chlorpyrifos, tebuconazole, dimethipin, total permethrin (cis- & trans-), ethoprop, tribufos, oxyfluorfen. • Three brominated HAA groups: HAA5 (dibromoacetic acid, dichloroacetic acid, monobromoacetic acid, monochloroacetic acid, and trichloroacetic acid) HAA6Br (bromochloroacetic acid, bromodichloroacetic acid, dibromoacetic acid, chlorodibromoacetic acid, monobromoacetic acid, and tribromoacetic acid) HAA9 (bromochloroacetic acid, bromodichloroacetic acid, chlorodibromoacetic acid, dibromoacetic acid, dichloroacetic acid, monobromoacetic acid, monochloroacetic acid, tribromoacetic acid, and trichloroacetic acid) • Three alcohols: 1-butanol, 2-propen-1-ol, and 2-methoxyethanol. • Three semivolatile organic chemicals: butylated hydroxyanisole, o-toluidine, and quinoline. Manganese and HAAs were detected during the UCMR4 sampling events. The results will be reported in the 2019 & 2020 Water Quality Reports (CCRs). While these contaminants do not have established drinking water standards, the data collected during UCRM4 provides a basis for potential future regulatory actions by EPA to protect public health. 32 Sources: WAC 246-290-300(10), 40 CFR 141.40 33 Sources: WAC 246-290-72005, 40 CFR 141.153(d) Appendix A COLIFORM MONITORING MANUAL Coliform Monitoring Manual Table of Contents 1) Reference Guide Responding to Bacteria Presence discovered during Routine Water Distribution System Sampling 2) Coliform Monitoring Plan 3) Maps showing Coliform Sampling Site Locations 4) Self‐Assessment Guideline for Coliform Detection Reference Guide Responding to Bacteria Presence discovered during Routine Water Distribution System Sampling Response to a Total Coliform-Positive Sample taken during Routine Distribution System Coliform Bacteria Sampling 1.

After Hours: 253-312-1651 or 253-841-0732 The City has prepared this Coliform Monitoring Plan in accordance with Washington Administrative Code (WAC) 246-290 Part 4 and 40 CFR 141 Subpart Y. The Plan supplements the City’s 2019 Water System Plan and updates the 2012 Coliform Monitoring Plan. The purpose of this plan is to ensure the City’s water quality monitoring program meets the regulatory requirements of the Revised Total Coliform Rule (RTCR) and the Ground Water Rule (GWR). The plan identifies coliform sampling sites and provides a schedule for coliform sample collection. Total coliforms are used as an indicator of possible bacterial contamination in the water system. Total coliform bacteria are usually not harmful themselves, but their presence indicates the possible presence of disease-causing organisms. Routine coliform testing is required on a monthly basis with the number of samples based on the population served. All samples are tested for total coliform. If total coliforms are present, the sample is also tested for E.coli and repeat samples are collected from designated sampling locations. In addition, chlorine residual must be measured and reported with each routine coliform sample. The City provides primary disinfection (4-log virus treatment) at each source. Even though the City is not subject to triggered source water monitoring per the GWR, the City voluntary collects source water (untreated) samples during the routine coliform monitoring of the distribution system. This allows the City to know immediately if the presence of total coliform in the distribution system is due to fecal contamination in a source of supply. The source water monitoring also provides water quality information that can be used in future planning decisions. I.

SAMPLING INFORMATION The City is responsible for collecting coliform samples from the sources of supply and representative points throughout the distribution system. Samples are collected at regular time intervals each month and during normal system operating conditions. Chlorine residuals within the distribution system are measured at the same time and location as routine and repeat coliform samples. Routine Samples: Routine samples are used to confirm the effectiveness of treatment and ensure public health protection throughout the distribution system from bacterial contamination. Per WAC 246-290-300(3), the minimum number of monthly routine samples required by the DOH is 100. On a weekly schedule, the water utility collects 27 samples from the designated routine sampling sites identified in the table below. Routine samples are collected on a Tuesday or Wednesday so that the results will be received by Thursday. This provides time during the work week to respond to positive samples. If a routine sample is total coliform-positive (and not invalidated): 1) the sample must also be analyzed for E.coli; 2) three repeat samples must be collected within 24 hours of being notified of the positive result; 3) verify raw source samples were taken or collect triggered source water samples within 24 hours from each source that was in operation on the day the positive sample was taken; and 4) notify the DOH within 10 days of being notified of the positive result. This must be done for each unsatisfactory routine sample. If E.coli are present upon further analysis, the City must notify the DOH immediately. The laboratory is not required to notify DOH. Additional treatment must not be started prior to the collection of repeat samples. The DOH may provide guidance on interim treatment options. Repeat Samples: Repeat samples are used to confirm the original sample results and to help determine the cause of the coliform presence. If a routine sample is total coliform-positive, at least one repeat sample must be collected from: • sample tap where the original positive sample was taken; • sample tap within five active connections upstream of the original sample site; and • sample tap within five active connections downstream of the original sample site. Designated upstream and downstream repeat sampling sites are identified in the table below. When a repeat sample is positive, the DOH should be notified as soon as possible and the City may ask for instructions on repeat sampling. If the DOH cannot be contacted, the same steps should be taken as a positive routine sample. A total coliform-positive repeat sample must also be analyzed for E.coli and an additional set of repeats is required. Additional sets of repeat samples should continue to be collected until total coliforms are not detected in one complete set of repeat samples or as directed by DOH. If a repeat sample is positive for E.coli, the City must immediately contact the DOH. Routine and Repeat Sampling Site Locations: Routine and repeat sampling sites are also shown on the site maps.

Per WAC 246-290-300(3)(h), triggered source water samples are taken from each groundwater source in use when an unsatisfactory routine sample is collected. As a proactive approach, the water utility collects raw source water samples during all routine coliform monitoring of the distribution system. The source samples are analyzed for E.coli presence. If a source water sample is E.coli-positive (and not invalidated), the City must: 1) immediately notify the DOH; 2) collect five additional raw water source samples from the same source within 24 hours of being notified of the positive result; 3) provide Tier 1 public notice; and 4) take corrective action, if directed by the DOH.

DOH Contacts – Coliform Water Quality Monitoring Program Carol Stuckey carol.stuckey@doh.wa.gov 253-395-6775 Ingrid Salmon ingrid.salmon@doh.wa.gov 253-395-6775 After-Hours Emergency Hotline: 1-877-481-4901 City of Renton Public notification messages should be approved by the Public Information Officer, City of Renton Executive Department, and Communications Division (unless urgency is immediate and coordination with the Communications Division is not possible). The Public Information Officer will assist with message delivery. Renton Public Information Officer: 425-430-7573 After hours contact for the Mayor, Chief Administrative Officer, Public Works Administrator, Utility Systems Director, and other public officials can be obtained from Emergency Management. Renton Emergency Management: 425-430-7723 Renton EOC Duty Officer: 425-766-2720 (answered 24/7) Notification Delivery: There are a variety of methods that can be used for the public notification efforts. Methods to convey public notification include: • City of Renton website at www.rentonwa.gov • Renton Current Emergency Information website at www.rentonwa.gov/emergencies • CodeRED Emergency Notification System • Social media posting (Facebook, Twitter, etc.) • Posting information at neighborhood information centers • Posting information at City facilities • Government Access Channel (Channel 21) • Broadcast media (television and radio) • Newspapers and other print media • Electronic media • Community meetings and other outreach activities • Recording for on-hold callers to utility customer service phone number Notification Responsibility: It is exclusively the responsibility of the City to comply with the public notification requirements of WAC 246-290 Part 7, Subpart A and 40 CFR 141 Subpart Q. The DOH is not required to issue public notification. The DOH and the City of Renton Public Information Officers are available to assist with public notification. VI. FOLLOW-UP ACTION Treatment Technique Triggers: The City must conduct an assessment after exceeding a “treatment technique trigger.” The assessment is used to determine the cause of the coliform bacteria contamination and identify corrective actions for any detected sanitary defects. There are two levels of assessment (Level 1 and Level 2) based on the severity or frequency of the problem. Requirements for the assessments are described in WAC 246-290-320(2)(b). Level 1 Treatment Technique triggers: • exceeds 5.0 percent total coliform-positive samples for the month; or • failure to collect three repeat samples after every total coliform-positive sample. Level 1 assessments are considered “self-assessments” and will be conducted by the water utility. The water utility has prepared the guidance document “Self-Assessment Guidelines for Coliform Detection” to use during a system evaluation. The guidance document is included in the Coliform Monitoring Manual. Level 2 Treatment Technique triggers: • an E.coli MCL violation; or • a second treatment technique trigger within a rolling 12-month period. Level 2 assessments must be conducted by a state-qualified person or the DOH. An assessment must be completed within 30 days after the trigger occurs. If corrective actions are not completed by the time of submission of the assessment, the City must consult with the DOH to develop an approved timetable for the corrective actions. The City shall maintain documentation of any Level 1 or Level 2 assessment, documentation of corrective actions completed as a result of the assessments, or any other summary documentation of the sanitary defects and corrective actions. ** Make sure to take photos and detailed notes for each corrective action** VII.

Use of this language does not relieve you of your obligation to take steps reasonably calculated to notify all persons served: Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail. RTCR Public Notification Templates 5 Instructions for Revised Total Coliform Rule (RTCR) E. coli MCL Violation Notice – Template 1-2 Template Follows Instruction Pages Description of Violation or Situation Beginning April 1, 2016, an E. coli maximum contaminant level (MCL) violation requires Tier 1 public notification. This violation occurs when any public water system has: • A total coliform-positive routine sample result followed by an E. coli-positive repeat sample result; • An E. coli-positive routine sample result followed by a total coliform-positive repeat sample result; • An E. coli-positive routine sample result and fails to take all required repeat samples; or • A total coliform-positive repeat sample result and fails to test for E. coli. You must provide public notice to persons served as soon as practical but no more than 24 hours after learning of the MCL violation [40 CFR 141.202(b)]. During this time, you must also contact your state. You should also coordinate with your local health department. You must use one or more of the following methods to deliver the notice to consumers [40 CFR 141.202(c)]: • Radio • Television • Hand or direct delivery • Posting in conspicuous locations • Another method approved in writing by the state You may need to use additional methods (e.g., newspaper or delivery of multiple copies to hospitals, clinics, or apartment buildings) since notice must be provided in a manner reasonably calculated to reach all persons served. If you post or hand deliver, EPA recommends printing your notice on your system’s letterhead, if you have it. The notice on the reverse is appropriate for hand delivery or for publication in a newspaper. However, you may wish to modify it before using it for a radio or television broadcast. If you do modify the notice on the reverse, you must still include all required public notice elements from 40 CFR 141.205(a) and leave the mandatory language unchanged (see below). Mandatory Language Mandatory language on health effects (from Appendix B to 40 CFR 141 Subpart Q) must be included as written and is presented in this notice in italics with an asterisk on each end. You will need to update the information presented in brackets with the appropriate information. You must also include standard language to encourage the distribution of the public notice to all persons served, where applicable [40 CFR 141.205(d)]. This language is also presented in this notice in italics with an asterisk on each end. Alternative Sources of Water If you are selling or providing bottled water, your notice should say where it can be obtained. Remember that bottled water can also be contaminated. If you are providing bottled water, make sure it meets U.S. Food and Drug Administration (FDA) and/or state bottled water safety standards. Corrective Action In your notice, you must describe corrective actions you are taking [40 CFR 141.205(a)(7)] and when you expect to return to compliance or resolve the situation [40 CFR 141.205(a)(8)]. Listed below are some steps commonly taken by water systems with the presence of E. coli. Depending on the corrective action you are taking, you can use one or more of the following statements, if appropriate, or develop your own text: • We are completing a comprehensive assessment of our water system and of our monitoring and operational practices to identify and correct any causes of the contamination. • We are chlorinating and flushing the water system. • We are switching to an alternate drinking water source. • We are increasing sampling for coliform bacteria to determine the source of the contamination. • We are repairing the wellhead seal. RTCR Public Notification Templates 6 • We are repairing, cleaning, and disinfecting the storage tank. • We are restricting water intake from the river/lake/reservoir to prevent additional bacteria from entering the water system and restricting water use to emergencies. After Issuing the Notice Make sure to send a copy of each type of notice and a certification that you have met all the public notification requirements to your state within 10 days after the original or any repeat notice(s) [40 CFR 141.31(d)]. It is recommended that you notify health professionals in the area of the violation. People may call their doctors with questions about how the violation may affect their health, and the doctors should have the information they need to respond appropriately. In addition, health professionals, including dentists, use tap water during their procedures and need to know about the potential contamination so they can use bottled water. It is a good idea to inform your consumers when the violation has been resolved. See Template 1-6 of the Revised Public Notification Handbook (2nd Revision of Document: EPA 816-R-09-013, March 2010) for a “problem corrected” notice template and Template NC-7 of the Public Notification Handbook for Transient Non-community Water Systems, EPA 816-R- 09-009, March 2010. RTCR Public Notification Templates 7 Revised Total Coliform Rule (RTCR) E. coli MCL Violation Notice – Template 1-2 DRINKING WATER WARNING E. coli is present in [Water System Name]’s water BOIL YOUR WATER BEFORE USING [Briefly describe the situation, such as: “E. coli bacteria were found in the water supply on [give date]” or “We did not perform required testing of the water system and must assume that E. coli bacteria are in the water as of [give date]]. These bacteria can make you sick, and are especially a concern for people with weakened immune systems. Bacterial contamination can occur when increased run-off enters the drinking water source (for example, following heavy rains). It can also happen due to a break in the distribution system (pipes) or a failure in the water treatment process. What should I do? What does this mean? • DO NOT DRINK THE WATER WITHOUT BOILING IT FIRST. Bring all water to a boil, let it boil for one minute and let it cool before using, or use bottled water. Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation until further notice. Boiling kills bacteria and other organisms in the water. • *E. coli are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Human pathogens in these wastes can cause short-term effects, such as diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a greater health risk for infants, young children, the elderly, and people with severely compromised immune systems.* • The symptoms above are not caused only by organisms in drinking water. If you experience any of these symptoms and they persist, you may want to seek medical advice. People at increased risk should seek advice from their healthcare providers about drinking this water. What is being done? [Describe corrective action]. We will inform you when tests show no bacteria are present and you no longer need to boil your water. We anticipate resolving the problem within [estimated timeframe]. For more information, please contact [name of contact] at [phone number] or [mailing address]. General guidelines on ways to lessen the risk of infection by bacteria and other disease-causing organisms are available from the EPA Safe Drinking Water Hotline at 1-800-426-4791. *Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses).

RTCR Public Notification Templates 17 Instructions for Revised Total Coliform Rule (RTCR) Failure to Perform any Level 1 Assessment or a Level 2 Assessment that is Not Triggered by E. coli MCL Violations or the Related Corrective Actions – Template 2-21 Template Follows Instruction Pages Description of Violation or Situation Beginning April 1, 2016, a public water system triggers a Level 1 assessment when: • For systems taking 40 or more samples (including routine and repeat samples) per month, the public water system exceeds 5.0 percent total coliform-positive samples for the month; • For systems taking fewer than 40 samples (including routine and repeat samples) per month, the public water system has two or more total coliform-positive samples in the same month; or • The public water system fails to take every required repeat sample after any single routine total coliform-positive sample. Also beginning April 1, 2016, a public water system triggers a Level 2 assessment when: • The public water system has a second Level 1 assessment treatment technique (TT) trigger within a rolling 12-month period unless the state has determined a likely reason for the total coliform-positive samples that caused the initial Level 1 assessment TT trigger, and the state establishes that the system has fully corrected the problem; or, • For public water systems with approved reduced annual monitoring, the system has a Level 1 assessment TT trigger in two consecutive years. Treatment technique (TT) violations related to triggered assessments occur when any public water system has: • Failed to conduct the triggered Level 1 or Level 2 assessment within 30 days after learning that it has exceeded the trigger; or • Failed to correct any sanitary defect found through a Level 1 or Level 2 assessment within 30 days or in accordance with a schedule acceptable to the state. TT violations related to any Level 1 assessment or to a Level 2 assessment that is not triggered by an E. coli MCL violation require similar Tier 2 public notice. TT violations for Level 2 assessments that are triggered by E. coli MCL violations require different mandatory health effects language and are addressed in Template 2-22. You must provide public notice to persons served as soon as practical but no later than 30 days after you learn of the violation [40 CFR 141.203(b)]. You must issue a repeat notice every three months for as long as the violation persists. Check with your state to make sure you meet all its requirements. Community water systems (CWSs) must use one of the following methods to deliver the notice to consumers [40 CFR 141.203(c)]: • Hand or direct delivery • Mail, as a separate notice or included with the bill (if delivered within 30 days of the violation) • Another method approved in writing by the state Non-community water systems (NCWSs) must use one of the following methods to deliver the notice to consumers [40 CFR 141.203(c)]: • Posting in conspicuous locations • Hand delivery • Mail • Another method approved in writing by the state In addition, both CWSs and NCWSs must use another method reasonably calculated to reach others if they would not be reached by the first method [40 CFR 141.203(c)]. Such methods could include newspapers, e-mail, or delivery to community organizations. If you mail, post, or hand deliver, EPA recommends printing your notice on your system’s letterhead, if available. RTCR Public Notification Templates 18 The notice on the reverse is appropriate for mailing, posting, or hand delivery.

One of the significant requirements of the rule is that utilities must attempt to find and fix the source of coliform bacteria contamination by performing a “self-assessment” whenever treatment technique trigger occurs. The self-assessment is designed to identify whether any sanitary defects are present and correct the defects. The guideline below is designed to assist City staff with performing the self-assessment. Office Level Review The following questionnaire is designed to provide an office level review for possible sources of contamination that led to the positive coliform bacteria water sample. This questionnaire is not designed to replace field level investigation. A YES answer to any of the questions below indicates further investigation is warranted. Question: Y or N Sampler, Sample Site, Laboratory Contamination: ---------- - When coliform bacteria is found in a water quality sample, the first area of scrutiny should be the possibility of the sample becoming contaminated by a source outside of the distribution system. These outside sources of contamination include the sampler, the sample site, and the testing laboratory. ---------- 1 Were procedures properly followed when the sample was collected? 2 Is the sampler experienced in collecting coliform bacteria samples? 3 Was the sample collected at a designated coliform bacteria sample sampling station? 4 Has the sampling station been properly maintained? 5 Did the sampler notice anything unusual about the sample station, the water flushed prior to collecting the sample or the surrounding environment when the sample was collected? 6 Was the sample transported to the laboratory using proper procedures? 7 Is the laboratory up to date on its sterility procedures and all other laboratory quality control & quality assurance procedures? 8 Taking into consideration all of its clients, has the laboratory been seeing an increase in the number of positive coliform bacteria samples recently, which may indicate laboratory contamination of these samples? Page 2 of 7 Review of Existing Water Quality Data: ---------- Recent water quality data may help expose problems within the distribution system which could have led to a coliform bacteria positive sample. A change in water quality parameters can also lead to a release of coliform bacteria from biofilms and sediments. ---------- 9 In general has recent water quality data been consistent with past data? 10 Are the chlorine residual levels that where measured when collecting the most recent round of bacteriological samples reflective of past chlorine residual levels? 11 Has anything unusual been noticed or detected when collecting water quality samples for other parameters recently, for example during VOC, Inorganics, Nitrate or Disinfection By-products sampling? 12 Is there any reason to believe the water temperature in the distribution system has increased or fluctuated? 13 Does the SCADA data for the chlorine analyzers on the primary disinfection systems at the sources show any lapse in the chlorine injection to the raw water supply? 14 Does the SCADA data for the pH adjustment systems located at the Downtown Wells and Springbrook Springs show any recent periods of high or low pH readings? Water Main Repairs: ---------- Coliform bacteria contamination of the distribution system via a water main break or main break repair is possible considering the sub-surface environment in which water mains are located. ---------- 15 Have there been any water main repairs in the last few months? a. If so were proper main repair procedures followed, including maintenance of positive water pressure at the break until the break was excavated and cleaned? b. Was the repaired area of the damaged main disinfected and the main flushed prior to returning the main to service? c. Does the AMI system show reverse flow through any meters at or near the time of the main break? Page 3 of 7 New Main Construction: ---------- The connection of a newly constructed water main provides a conduit for contamination of the water system if the new water main has not been properly cleaned and disinfected. ---------- 16 Have new water mains been connected to the water distribution system recently? a. Is there documentation that shows that all procedures for the new main construction and tie-in procedure were properly followed? b. Was there anything unusual noticed by the utility inspector who inspected the main construction or the maintenance crew who connected the main to the system? Reservoirs: ---------- Water storage tanks have multiple openings to the environment including air vents, overflow pipes, and access hatches which can provide conduits for contamination to enter the water distribution system. ---------- 17 Has anything unusual been noticed at any of the reservoirs during routine station checks, for example unlocked gates, ladders or hatches? 18 Were any screens (air vent and overflow) or hatches found damaged during the latest round of reservoir inspections? 19 Is the reservoir cleaning program on schedule? Distribution System Maintenance and Operation: ---------- Coliform bacteria may be found in biofilms and sediment located in the water distribution system. Operations which disrupt biofilms and sediments may release large amounts of coliform bacteria into the free flowing water. ---------- 20 Have any water mains been flushed lately? 21 Have any valves been exercised recently or changed operational status (open to closed)? 22 Have there been any operational changes that may have changed the typical flow path or velocity of water in the distribution system? 23 Has there been a recent fire or fire training exercise which consumed large amounts of water? 24 Have any control alarms been disabled that may have provided a warning of an event that can affect water system quality? 25 Has there been any maintenance lately of systems that come into contact with the water supply? For example chemical dosing systems. Page 4 of 7 Sanitary Survey: ---------- Sanitary Surveys are designed to locate and correct possible sources of contamination of the drinking water supply system. ---------- 26 Have all issues discovered in the latest sanitary survey been addressed? Cross Connection Control: ---------- The City’s Cross Connection Control Specialist (CCS) may be able to provide information that is relevant to bacteria contamination found in the distribution system. ---------- 27 Is the CCS aware of any recently discovered cross connections or backflow incidents that may have led to bacteria contamination of the water distribution system? Other: 28 Is there maintenance activity underway or recently completed which may have led to a positive bacteria sample? Consider all activity at all sites and all locations within the distribution system. 29 Have any sources exceeded the allowable flow rate recently? 30 Has there been a power outage or other disruption to the normal operation of the water supply system recently? 31 Is it possible that the contamination is related to the time of year? For example irrigation system winterizing activities. Page 5 of 7 Field Level Investigation Maintenance Services field crews, operators and technicians repair, operate, and maintain the water system on a daily basis and as such may observe unusual events, activities, trends etc. These observations may provide a lead to investigators looking for the source of coliform bacteria contamination of the water system. Field level staff should be encouraged to report anything unusual they find as they perform their daily functions. The following list is intended as a guide for performing field level investigation to locate the source of the bacteria contamination of the distribution system. The list is not presented in order of importance. Maintenance Services managers can schedule the field inspections based on staff availability and on the details of the bacteria contamination event, for example location of the positive sample.

Appendix B STAGE 2 DISINFECTANTS AND DISINFECTION BYPRODUCTS MONITORING PLAN The City has prepared this Stage 2 Disinfectants and Disinfection Byproducts Monitoring Plan in accordance with Washington Administrative Code (WAC) 246-290 Part 4 and 40 CFR 141 Subpart V. The Plan supplements the City’s 2019 Water System Plan and updates the 2012 Stage 2 Disinfectants and Disinfection Byproducts Monitoring Plan. The purpose of this plan is to ensure the City’s water quality monitoring program meets the regulatory requirements of the Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts Rules (D/DBPR). This plan identifies D/DBPR sampling sites and provides a schedule for sample collection. The City provides disinfection treatment to protect public health from possible harmful bacterial contamination. The City adds chlorine at each source and maintains a detectable chlorine residual throughout the distribution system. While chlorination is a proven method for ensuring safe drinking water, there is a possibility for disinfection byproducts to form when the chlorine reacts with naturally-occurring organic matter present in the water. The most common disinfection byproducts are Trihalomethanes (TTHM) and Haloacetic acids (HAA5). Because there is some concern that high concentrations of disinfectants and disinfection byproducts may cause adverse health effects, the City performs distribution system monitoring. I.

SAMPLING INFORMATION The City is responsible for collecting samples for disinfection byproducts and disinfectant residuals in the distribution system. Samples are collected during normal system operating conditions. Disinfection Byproducts D/DBPR samples are required from locations where the highest levels of TTHM and HAA5 have been measured in the distribution system. The City has a 40/30 certification and is currently on a reduced monitoring schedule. Maximum Contaminant Levels: 80 µg/L for TTHM and 60 µg/L for HAA5 Compliance Calculation Procedures: Compliance is based on the locational running annual average (LRAA) for TTHM and HAA5 Reduced Monitoring Frequency: Once per year, typically in August Number of Samples Required for Reduced Monitoring: 2 dual sample sets: one at the location with the highest TTHM single measurement, one at the location with the highest HAA5 single measurement Distribution System Sampling Locations for Reduced Monitoring: Sampling Station Name Water Quality Database ID 1622 Hoquiam PL NE Sampling Station MS034 3000 Royal Hills Dr. Sampling Station MS041 Reporting: The City reports the range of detected concentrations of TTHM and HAA5 in the annual Consumer Confidence Report (water quality report). Disinfectant Residuals Chlorine residuals are required to be measured at the same times and same locations as routine and repeat coliform samples. Maximum Residual Disinfectant Level: 4.0 mg/L as Cl2 Compliance Calculation Procedures: Compliance is based on the running annual average (RRA) of residual measurements for 12 consecutive months. The RAA is calculated by finding the average of all residual measurements for each month, adding 12 consecutive monthly averages together, and then dividing the sum by 12. The RAA must be calculated at the end of each calendar quarter. Daily residual measurements are included in the compliance calculations. Monitoring Frequency and Sampling Locations: The City collects chlorine residual samples from 27 representative points throughout the distribution system on a weekly basis during RTCR compliance monitoring (see Appendix A for the designated routine sampling sites) Reporting: The City reports the chlorine residual on each routine coliform sample form. In addition, the City reports the range of detected chlorine residuals in the annual water quality report. III.

PUBLIC NOTIFICATION The DOH must be notified within 48 hours of a MCL (TTHM or HAA5) or MRDL (chlorine) violation. In addition, a Tier 2 public notification must be issued to customers within 30 days of the violation. Failure to collect required chlorine residual samples is a monitoring violation that triggers a Tier 3 public notification, which must be issued within 1 year. Public notice templates are provided in the Coliform Monitoring Manual. V. LRAA Calculations The locational running annual averages (LRAA) for TTHM and HAA5 were calculated at eight monitoring locations with the most recent quarterly data collected for Stage 2 D/DBPR compliance using: LRAA = (Q1+Q2+Q3+Q4)/4 for each monitoring location Sampling Station Name Water Quality Database ID TTHM LRAA HAA5 LRAA 1622 Hoquiam PL NE Sampling Station MS034 9.9 µg/L 4.2 µg/L 3000 Royal Hills Dr. Sampling Station MS041 7.4 µg/L 1.2 µg/L 601 Monster Rd SW Sampling Station MS042 5.6 µg/L 0.3 µg/L Fire Hydrant NW040 DBP_Smpl_Site_7 4.7 µg/L 1.0 µg/L Fire Hydrant SW541 DBP_Smpl_Site_8 4.3 µg/L 0.7 µg/L Fire Hydrant NW065 DBP_Stage2_8 4.2 µg/L 1.0 µg/L Jones Ave NE & NE 43rd St Sampling Station MS027 2.9 µg/L 0.5 µg/L S 180th & West Valley Sampling Station MS028 2.6 µg/L 0 µg/L In accordance with WAC 246-290-300(6), a reduced monitoring schedule is allowed when the LRAA for TTHM is less than 40 µg/L and HAA5 is less than 30 µg/L at all monitoring locations. Based on the LRAA calculations above, the City is eligible for a reduced monitoring schedule. The City may remain on reduced monitoring as long as each TTHM sample is less than 60 µg/L and each HAA5 sample is less than 45 µg/L. If either criteria is exceeded, the City must resume routine monitoring.

Purpose The City of Renton (City) has prepared this Water Shortage Response Plan (WSRP) to present viable options for reacting to a water supply shortage. The WSRP enables the City to maintain essential public health and safety while minimizing adverse impacts on economic activity, environmental resources, and the region’s water use preferences. Water shortages could result from forecasted, progressive events such as droughts, as well as immediate crises such as water system failures. This Plan supplements the City’s 2019 Water System Plan and updates the 1989 WSRP. This document builds upon information provided in the 2019 Water Shortage Contingency Plan prepared by Seattle Public Utilities (SPU). Renton purchases a portion of its water from SPU and thus might need to implement a shortage response in concert with SPU if an SPU source is compromised. Water system planning is required by WAC 246-290-100. The use and success of this Plan depends upon the accuracy of its contents. It is a working tool that needs to be maintained and updated on a regular basis. We recommend that this Plan be kept in the Operations Control Center at the City Shops, and in the Water Utility department in City Hall for easy reference. We also recommend that this Plan be incorporated into the Emergency Response Plan. B. Water System Overview The City’s water system provides service to an area of approximately 17.25 square miles that is largely coincident with the city limits. The water distribution system serves the valley floor and parts of five surrounding hills: West Hill, the Highlands, Scenic Hill (also known as Renton Hill), Talbot Hill, and Rolling Hills. The City currently serves 17,830 customers (service connections) within an elevation range of 11 to 475 feet. Additionally, the city supplies wholesale water to Skyway Water and Sewer District (Skyway) through a single- metered connection. The City owns and operates a multi-source municipal water system including supply, treatment, storage, and distribution of potable water to residential, commercial, industrial, and wholesale customers. The City’s water distribution system consists of more than 300 miles of pipeline. Water supply sources include the Downtown Wellfield, encompassing wells RW-1, RW-2, RW-3, PW-8, and PW-9. These production wells draw from a relatively shallow aquifer (Cedar Valley Aquifer), which is an underground layer of sand and gravel that runs 3 1/2 miles long and at some points is only 23 feet below ground surface. The aquifer is fed by rain and snow falling on the aquifer and higher adjacent ground, as well as by groundwater flow from the Cedar Valley. As the City's primary water source, the Cedar Valley Aquifer has been designated a "sole source" by the U.S. Environmental Protection Agency. On average, water sourced from the Downtown Wellfield provides 60 to 65 percent of the City’s total water supply. Springbrook Springs, an artesian spring located at the south end of the City’s water service area, is used for normal supply as well. On average, water sourced from Springbrook Springs provides 15 to 20 percent of the City’s total water supply. The Maplewood Wells provides an alternate source of supply in the event of the contamination of the Downtown Wellfield as well as supplementary (non-additive) supply during high demand periods. The three production wells (PW-11, PW-12, and PW-17) are located east of the downtown area, within the Maplewood Golf Course. On average, water sourced from the Maplewood Wells provides 15 to 20 percent of the City’s total water supply. 4 In addition, the City is a wholesale customer of SPU, which gets its supply from the Cedar and Tolt Rivers. The City currently only buys wholesale water from SPU to sell directly to the Boeing Renton Plant, but the City has a long-term supply contract for backup supply during summer peak use periods and for future water demands. On average, water sourced from SPU provides 1 to 2 percent of the City’s total water supply. As a result of the City’s topography and geography, the City has 16 hydraulically distinct pressure zones. Pumping throughout the water system is accomplished by 12 booster pump stations (BPS) that are located throughout the City. Currently there are 10 reservoirs in the system, strategically located to provide adequate equalizing and fire flow reserves for all pressure zones. Pressure reducing valves (PRVs) are used to supply lower pressure zones from higher pressure zones that contain water storage reservoirs. The City has seven metered interties with the SPU transmission mains and three additional emergency supply interties with other neighboring water systems. The City’s retail service area (RSA) is bordered by nine adjacent water systems. It is unlikely that the City’s RSA will change much in the future due to the geography of the surrounding areas and the fact that all of the surrounding areas are currently served by other water purveyors. Copies of current service agreements between the City and the adjacent water purveyors are included in Appendix D of the Water System Plan. C. Relationship to Seattle Public Utilities This Plan covers both City and SPU strategies in the case of a water shortage. While most of the City’s water is produced by its own wells and spring, the City supplies its Boeing Plant through SPU interties, purchasing approximately 43 million gallons of water in 2018. These interties also allow SPU to provide the City water in the event of a shortage. The main concern for the City is a shortage caused by limited water production from the Cedar Valley Aquifer. This report focuses on what to do during a shortage of City-supplied water, however, it can also be used in the event of SPU implementing its own shortage response plan. This is because a water shortage affecting SPU’s water supply not only affects their retail customers, but could affect SPU’s wholesale customers and their respective retail customers. SPU’s wholesale water contracts include a provision that wholesale customers will assist and support actions required to manage demand during a shortage or an emergency. When SPU activates its shortage response plan, it will request that each wholesale customer also activate their own shortage response plan at the same stage currently being implemented by SPU. Appendix A contains a list of customer outreach actions proposed by SPU, which can be applied during an SPU shortage event as well as a Renton-only shortage event. SPU developed their shortage response plan in consultation with its wholesale customers and other participants, based on the premise that an effective demand management strategy must be regionally consistent. This is based on several considerations: • Shortage Should Be Shared: Shortage and risk must be shared among all beneficiaries of the water resource, including all water utilities obtaining water from the Seattle regional water supply system. • Unified Message: A unified/regional message and approach is easier to understand and distribute through the media, which is key in communicating information to the public. • Consistency Aids Forecasting: Consistency makes it easier for SPU to forecast demand reductions, which is essential to effectively manage the system during a water shortage. 5 D. Overview of Water Shortage Response Stages This Plan has four water shortage response stages – Advisory, Voluntary, Mandatory, and Emergency – which are typically implemented progressively depending on the magnitude of the water shortage. In the event of an immediate crisis, the WSRP may be activated at one of the more aggressive stages. Each stage contains a variety of strategies for managing aspects such as supply, utility operations, customer actions, and communications. The four stages of the WSRP are described below. The key aspects of each stage are provided in Table 1. • Advisory Stage: The WSRP typically begins in the Advisory Stage when the City recognizes there is a serious potential for a water shortage. At this stage, the City implements supply management actions, planning activities, and coordination with other City departments, State agencies, and wholesale customers. No customer action is requested at this stage. However, customers and the media may start to inquire about the potential for a water shortage and the City should be ready to answer questions. The authority to enter the Advisory Stage, which in most cases will activate the WSRP, lies with the City’s Public Works Administrator. • Voluntary Stage: If supply conditions worsen, the WSRP moves to the Voluntary Stage. This stage relies on the voluntary cooperation and support of customers to meet target reduction goals. During the Voluntary Stage, specific voluntary actions are suggested for residential and commercial customers. The suggested customer actions are a combination of standard conservation practices (e.g., avoid watering mid-day) and curtailments that require customers to reduce their water use, which may result in sacrifice (e.g., take a shorter shower). The level of that sacrifice will depend on the severity of the water shortage. The authority to enter the Voluntary Stage lies with the City’s Public Works Administrator. • Mandatory Stage: If the Voluntary Stage does not produce needed water use reductions, or if supply conditions worsen, the Mandatory Stage would be implemented. This stage prohibits or limits certain actions, which may be accompanied by an enforcement plan, which could include fines for repeated violation, as well as exemptions. The customer actions in this stage reflect a more aggressive approach that requires deeper levels of customer sacrifice (e.g., restricting irrigation). This stage may also include rate surcharges, although careful consideration would be required of the impacts of those charges. The authority to enter the Mandatory Stage lies with the Renton City Council (Council). • Emergency Stage: This stage addresses the most severe need for demand reduction and includes a combination of mandatory actions and rate surcharges. This would be the last stage used to address a progressive situation, such as a drought of increasing severity, or to respond to an immediate crisis, such as a major facility failure or contamination of the Cedar Valley Aquifer. The authority to enter the Emergency Stage lies with the Council, unless there is an immediate emergency, in which the City’s Mayor may authorize these actions. 6 Table 1.

Stages may be different for an immediate crisis. 8 II.IMPLEMENTATION CONSIDERATIONS A. WSRP Principles The City has learned how to operate effectively during water shortage events, while minimizing impacts to customers and water resources. This knowledge is reflected in this WSRP, and articulated in the following principles: • Plan Should Be Flexible: Each water shortage situation has enough unique characteristics that a plan cannot specifically define all the scenarios and specific supply and demand management actions. The usefulness of a Water Shortage Response Plan lies in planning the range of supply and demand management actions in advance of the situation, and in defining the communication mechanisms by which decisions will be made during the event. • Shortage Should Be Shared: A key assumption of this Plan is that abundance, shortage, and risk must be shared among all beneficiaries of the water resource. Since the City purchases water from SPU, the City will also participate in management of their water shortage. Similarly, all customer sectors of the City’s water should participate. • Conservation versus Curtailment: It is important to distinguish between the short-term curtailment actions necessitated by a water shortage event, and the conservation actions the City regularly promotes to its customers. Conservation focuses on long-term efficiencies which do not adversely affect customers’ accustomed use of water, whereas curtailment actions involve short-term water use reductions or restrictions that can create customer hardships. • Voluntary Preferred over Mandatory: Customers prefer the opportunity to meet targeted demand reduction levels through voluntary compliance actions. The decision to move to mandatory restrictions is more acceptable if the voluntary approach has been tried first, but has not resulted in sufficient demand reduction. • Safeguard Water Quality: It is essential to closely monitor water quality during water shortages. The City water distribution system is designed to carry a large capacity of water during summer peak months and for fire-fighting. If demand is substantially lowered, water quality can significantly degrade. Additionally, the water quality of surface water can be affected by warmer air temperatures. The City does not rely on surface water as a drinking water source, however, there is cause for concern about water quality during warm weather events because the City shares several supply interties with SPU, which sources its drinking water from the Tolt and Cedar Rivers. Therefore, water quality during water shortages, particularly during warm weather drought, should be monitored and managed more carefully than normal. B. Causes of Water Shortage The City relies on the Cedar Valley Aquifer to provide the majority of Renton’s drinking water, therefore it is the main source of concern during a water shortage. The amount of water available in the Cedar Valley Aquifer is contingent upon the amount of withdrawal versus replenishment. In the case of a drought, less water will infiltrate via precipitation into the City’s aquifer, potentially putting Renton’s water availability at risk. If the water provided by the Cedar Valley Aquifer is limited or unavailable, suggestions for next steps are available in this Plan. 9 Droughts are the most common reason a WSRP would be implemented. Droughts are naturally occurring, unpredictable weather events of varying frequency, duration, and severity. Renton’s water service area has experienced several short-term droughts, however, available data indicates a very low probability of a multi- year drought. Details on the three main types of droughts are provided below. Due to interties with SPU, some conditions that affect the Tolt and Cedar Rivers streamflow, such as low snowpack, are also addressed. Since the nature of these droughts varies, the City’s responses will also vary. Types of Droughts by Season Summer/Fall Drought: Droughts in the summer and fall are characterized by drier conditions and hotter temperatures. This typically results in both decreased supply and increased demand. Supply is decreased because less rain results in less infiltration of water into the aquifer. Demand is increased because outdoor water use (mostly irrigation) is higher at this time of year. The City attempts to manage for these types of droughts by carefully monitoring summer demands and water supply. Unfortunately, it is not possible to accurately predict in advance the timing and amount of the fall rains. A key management tool for this type of drought is helping customers to reduce irrigation use. Fall/Early Winter Drought: Droughts in the fall and early winter are characterized by the fall rainy season developing later than normal. Fall droughts are particularly challenging because that is when water demands for fish habitat needs are especially high and when the ability for people to reduce water is limited since the irrigation season is ending. Winter/Spring Drought: Droughts in the winter and spring are characterized by low snowpack. While low snowpack may not lead to poor water supply conditions if ample spring rains occur, caution is used in managing the water supply in these situations because rainfall is inherently difficult to forecast. Low snowpack can occur when mountain temperatures are warm, when precipitation is below average, when intense rainfall events melt low to mid-elevation snow, or through a combination of these factors. These types of droughts can be managed in several ways. Tracking El Niño events, which are typified in the Pacific Northwest by warmer and drier than average winter conditions, can alert water managers to the increased potential of a winter/spring drought. When winter/spring drought conditions result in low water supply availability, implementation of the WSRP may be necessary because the potential for water use reductions by customers is greater in the spring and summer, there is much uncertainty about impending summer weather which is so influential on demand, and weather forecasts of when the fall rains will begin are not reliable. These conditions generate uncertainty about whether water stored in the aquifer will be sufficient to meet demands until supplies are replenished in the fall. This can make implementation of the WSRP in the spring and summer necessary, despite the fact that in some of these years no water shortfall actually develops. 10 C. Demand Reduction A key strategy to managing a water shortage event is having customers reduce their water use. The WSRP does not pre-identify specific demand reduction actions for each stage. Rather, a comprehensive list of potential actions customers can take to reduce water use is provided at the end of each section in Section III, Implementation for a Progressive Event. The actual actions requested or required for each stage will depend on the severity, likely duration, and timing of the shortage, as well as the demand reduction needed. There are several criteria for deciding which demand reduction actions are appropriate during a water shortage. • Magnitude of Savings: Will the action result in enough savings to make a meaningful difference? • Timing: Can the action produce results in the necessary timeframe? • Duration of Event: What is the anticipated duration of the event (e.g. customers may tolerate certain mandatory curtailments if the event is expected to last a few weeks rather than months)? • Season: Is the action relevant to the time of year (e.g. banning lawn watering during summer irrigation season vs. during non-irrigation season)? • Costs: How severe are the cost implications of the action to the customer relative to the need for action? • Enforcement: For mandatory curtailment actions, is it desirable and practical to enforce the action? • Equity: Do the suite of actions cover all customer sectors and types of uses? D. Exemptions Appendix B provides background and a framework for developing and implementing exemptions to customer water use restrictions that are part of the Mandatory and Emergency stages of the WSRP. E. Financial Considerations Reducing water demand as needed to address a water shortage event can reduce revenues at a time when there is an increased need for these funds to cover costs associated with implementing the WSRP. The following issues should be considered: • Reprioritize Current Revenue: This consists of reducing revenue contributions to the capital program and lowering the year end operating cash target. These are the most flexible resources to offset revenue and expenditure problems. • Reprioritize Expenses: Reducing planned operations and maintenance expenditures can ease the demand on revenues or free up money to meet unexpected needs. • Rate Surcharge: In the mandatory and emergency stage, rate surcharges can be used to send a strong signal to customers to reduce water use. Rate surcharges can also help to make up revenues lost due to decreased demand. • State Drought Relief Funds: In a Washington State emergency drought declaration, funds in the form of grants or loans may be available to the City to mitigate the impacts of a water shortage. 11 III.IMPLEMENTATION FOR A PROGRESSIVE EVENT For each stage, the following information is provided.

Stages of a Water Shortage In order to reduce water demand throughout the city, demand reduction options have been developed for each of the four water shortage stages (Voluntary, Mandatory, Emergency), with an initial Advisory stage to notify residents that reductions may be occurring in the near future. These options have been adapted from SPU’s 2019 Water Shortage Contingency Plan. After determining that a serious potential for a water shortage exists, implementation of the WSRP begins with the activation of the WSRP. Plan initiation consists of two steps: 1. The City’s Public Works Administrator identifies a City staff member to lead the water shortage response effort; and 2. The City’s Public Works Administrator communicates the nature and scope of the WSRP stage actions and strategies to the Council (prior to activating the WSRP) and receives their input. Once the WSRP is activated, a two-prong effort ensues. The first effort is focused on implementing the initial stage (typically the Advisory Stage). The following effort is to begin planning for possible implementation of a subsequent stage. Typically, a minimum of two weeks is recommended before moving to a new stage, although four weeks may be more realistic to allow for carefully considered decision-making and appropriate planning time. When considering moving from one stage to another, the decision inputs are the same as for initiating the WSRP. A key aspect of implementing the WSRP is determining how and when to ramp down the stages and/or exit the WSRP. As soon as actual and forecasted supply conditions substantially improve, the City will either inform the public of the return to normal use of water, or inform them that the utility is moving to a lesser 12 stage of this Plan. This latter process would occur until there was a return to normal operations. Stages could be skipped in this process as conditions and forecasts warrant. B. Stage 1 – Advisory The WSRP typically begins in the Advisory Stage when the City recognizes there is a serious potential for a water shortage. At this stage, the City implements supply management actions, as well as formal planning activities and coordination with other City departments and State agencies. No customer action is requested at this stage. However, customers and the media may start to inquire about the potential for a water shortage and the City should be ready to answer questions. Triggers The City will enter the “Advisory Stage” if supply conditions and supply forecasts raise significant concerns about the utility’s ability to meet demand later in the year. Objectives • To prepare the Water Utility department, City, and relevant agencies for a potential water shortage, thereby allowing all parties adequate planning and coordination time in the event there is a need to move to the Voluntary Stage. • Stretch available supply through supply management actions. Stage Activation The authority to enter the Advisory Stage, which in most cases is effectively activating the WSRP, lies with the City’s Public Works Administrator. Demand Reduction Goal There is no demand reduction goal for the Advisory Stage because this stage is an internally focused stage that does not include outreach to customers. Key Public Messages Although the Advisory Stage is not intended to be a public stage, the City should be prepared to answer inquiries from the public and media as follows: • Planning: Due to the potential for a water shortage, the City has entered the planning phase of the WSRP to coordinate actions in the event we need to move to the Voluntary Stage. • Supply Conditions: Report on supply conditions and forecasts. • No Customer Action: At this time, customers are not being asked to take special action. If pressed: the City, in partnership with SPU, has an ongoing conservation program and always encourages customers to use water wisely. See www.savingwater.org for ways to use water wisely, indoors as well as outdoors, especially during the summer irrigation season. • Future Customer Action May Be Needed: Customers may be asked to reduce their water use if conditions worsen and we move to the next stage, the Voluntary Stage. Coordination and Communication Actions • General Customer Actions: 13 o No demand reduction actions will be requested of general customers for the Advisory Stage. Some proactive outreach to customers may occur reminding them to use water wisely. o Determine the list of customer demand reduction actions that would be requested if the WSRP advances to the Voluntary Stage. A list of potential actions customers can take to reduce water use is provided in Table 2. The actual actions selected for use will depend on the severity, likely duration, and timing of the shortage, as well as the demand reduction needed. • Wholesale Customers: Inform wholesale customers about the current water supply conditions that the Advisory Stage has been triggered, and that planning is underway in the event that elevation to the Voluntary Stage is needed. Request their cooperation. • Seattle Public Utilities: Implement coordination with SPU on goals and outreach for Voluntary Stage, if shortage is related to SPU water. • Outreach: Develop the initial communication and outreach plan, focusing primarily on the Voluntary Stage, including overall purpose, goals, audiences, and tools (e.g. FAQs, press releases, tips flyers). Include: We are experiencing a drought/shortage. We are asking everyone to help by… We have suggestions/requirements on how to reduce water use. Also see “Key Public Messages”. City Department Actions Develop potential demand reduction actions for City departments, including Parks department. Water Quality and Supply Management Actions • Data Collection: Increase data collection actions and monitoring of weather forecasts. • Modeling: Increase computer modeling runs of projected supply, storage, demand, and revenue scenarios. • Water Quality: Assess water quality in reservoirs and in distribution system to identify areas that may experience degradation with reduced consumption. Increase monitoring if appropriate. Additionally, assess current water main flushing and reservoir cleaning activities to determine whether they should be accelerated to be completed prior to the peak season or reduced to conserve supply. • Optimize Supplies: Identify and implement supply side management techniques to optimize existing sources. • Emergency Supplies: Ready emergency water supplies for use and activate if appropriate. Retail Customer Demand Actions • Current Demand Reduction Actions: No demand reduction actions will be requested of general customers for the Advisory Stage. Some proactive outreach to customers may occur reminding them to use water wisely. • Potential Demand Reduction Actions: Determine the list of customer demand reduction actions that would be requested if the WSRP advances to the Voluntary Stage. A list of potential actions 14 customers can take to reduce water use is provided in Table 2. The actual actions selected for use will depend on the severity, likely duration, and timing of the shortage, as well as the demand reduction needed. Wholesale Customers (Skyway) • Plan for Voluntary: Plan for the potential move to the Voluntary Stage. • Alternative Sources: Determine feasibility of activating independent or emergency supply sources, as appropriate. • Flushing: Assess current water main flushing and reservoir cleaning activities to determine whether they should be accelerated to be completed prior to the peak season or reduced to conserve supply. 15 Table 2. Potential Customer Demand Reduction Actions WSRP Stage Demand Reduction Action Communications Message Indoor Residential N/A Conservation Message Low-Flow Toilets If buying a new toilet, consider purchasing a low- consumption model. Look for a “WaterSense” or “Premium WaterSense” label, which uses far less water than older models. According to the Saving Water Partnership, 70 percent of residential water is used indoors, with toilets being the largest home water user. N/A Conservation Message Efficient Clotheswashers and Dishwashers If buying a new clotheswasher or dishwasher, consider buying a high-efficiency model that saves water and energy. Look for an “Energy Star” certified model. N/A Conservation Message Wash Full Loads Wash only full loads of laundry and dishes. N/A Conservation Message Don’t Hand-Wash or Pre-Rinse Dishes Dishwashers save more water than washing dishes by hand. Don’t pre-rinse dishes unless heavily soiled. Most new dishwashers don’t require pre-rinsing. Scrape plates instead. N/A Conservation Message Turn Off Tap Turn off the tap while brushing your teeth or shaving. N/A Conservation Message Minimize Garbage Disposal Put food waste in your compost bin, rather than using your garbage disposal. N/A Conservation Message Thaw in Fridge Thaw frozen food in the refrigerator, rather than under running water. N/A Conservation Message Efficient Fixtures Replace older bathroom faucets and showerheads with WaterSense models, which use far less water, or add a water-saving aerator or flow-restrictor to the existing plumbing fixture. Using low-flow showerheads will also save you money on your energy bills, by reducing the demand on your water heater. N/A Conservation Message Fix Leaks (Indoor) Check for and fix indoor leaks, such as faucets. Also, check your toilets for silent leaks. Put several drops of food coloring in your toilet tank. After 10 minutes, if you have color in the toilet bowl, you have a flapper leak. N/A Conservation Message Equipment Not in Use Turn off water-using equipment when not in use, including dishwashers, garbage disposals, and food troughs. N/A Conservation Message Efficient Showerheads Replace older showerheads with WaterSense models, which use far less water. N/A Conservation Message Other Water-Using Equipment Consider upgrading any other water-using equipment to models that are more efficient. Voluntary Shorter Showers (a) Reduce your showering time. Voluntary Shorter Showers (b) Reduce your showering time by one minute. Voluntary Shorter Showers (c) Reduce your showering time by two minutes. Voluntary Shower Showers (d) Limit shower to five minutes or less. Mandatory Less Toilet Flushing Flush your toilet less often. As the saying goes, “If it’s yellow, let it mellow.” Toilet flushing is the largest water use inside the home. Outdoor Residential N/A Conservation Message Use a Broom Not Hose Use a broom, rather than a hose, to clean sidewalks, driveways, and patios. Reducing water runoff also helps 16 to protect contaminants from entering storm drains, lakes, and rivers. N/A Conservation Message Hose Shut-Offs Never leave a hose running; always use an automatic shut-off nozzle. N/A Conservation Message Water Deeply, but Infrequently It’s better to have one or two deep waterings, rather than several shallow waterings. N/A Conservation Message Tune Up Automatic Systems Do an efficiency tune up of your automatic irrigation system such as fixing overspray onto sidewalks and ensuring sprinkler heads reach adjacent sprinkler heads. N/A Conservation Message Get Water to the Roots Use soaker hoses, drip irrigation, or watering wands to deliver water where it’s needed. N/A Conservation Message Water Young Trees Efficiently Water young trees efficiently using a water bag. Trees planted five or fewer years ago need 15 to 20 gallons of water twice a week to thrive. N/A Conservation Message Upgrade Automatic Systems Consider efficiency upgrades to your automatic irrigation system such as weather-based or soil-based controllers. N/A Conservation Message Two Inches of Mulch Put two inches of mulch on planting beds and around trees, which reduces evaporation. Keep the mulch a hands-width away from the trunk. N/A Conservation Message Mow High Set your lawn mower blade to cut grass two inches high, which reduces evaporation. N/A Conservation Message Water Early or Late Water before 8am or after 7pm, which reduces evaporation. N/A Conservation Message Pool and Hot Tub Covers Use covers on swimming pools and hot tubs when not in use to reduce evaporation. N/A Conservation Message Wash Vehicles Wisely Wash your vehicle(s) at locations that recycle the water. This saves water and avoids washing contaminants, such as soap, into storm drains and surface water. N/A Conservation Message Fix Leaks (Outdoor) Check for and fix outdoor leaks, such as hose bibs, spray heads, valves, and broken pipes. N/A Conservation Message Rain Barrels Consider using rainwater collection barrels. These can be used for watering gardens. Voluntary Eliminate One Watering Day Cut one day from your typical weekly watering schedule (except for young trees as noted elsewhere). Voluntary Eliminate Two Watering Days Cut two days from your typical weekly watering schedule (except for young trees as noted elsewhere). Voluntary Eliminate Three Watering Days Cut three days from your typical weekly watering schedule (except for young trees as noted elsewhere). Voluntary Water Twice a Week Maximum Limit plant watering to twice a week (except for young trees as noted elsewhere). Voluntary Water Once a Week Maximum Limit plant watering to once a week (except for young trees as noted elsewhere). Voluntary Water Young Trees Efficiently Water young trees efficiently using a water bag. Trees planted five years or fewer years ago need 15-20 gallons of water once a week to survive. (Note: this is only appropriate if the maximum temperatures are in the low 70’s with occasional showers and not peak daylight hours.) 17 Voluntary Let Lawn Go Dormant If your lawn isn’t already dormant (brown), let it go dormant until the fall rains return. Just water deeply once each month to keep roots alive. Voluntary Plant in Fall Consider delaying new plantings. Fall is the best time for planting new trees, shrubs and perennials, since rain provides natural irrigation. Voluntary Minimize Filling Pools and Hot Tubs Minimize refilling swimming pools and hot tubs. Voluntary Minimize Pressure Washing Do only essential pressure washing. Voluntary Minimize Vehicle Washing Reduce the frequency of, or eliminate, washing vehicles. Voluntary Turn off Water Features (a) Turn off non-recirculating water features such as certain fountains. Voluntary Turn off Water Features (b) Turn off all water features. Mandatory No Hose Washing Using a hose to clean sidewalks, driveways, and patios is prohibited. Must use a broom instead. Mandatory Water Twice a Week Maximum Plant watering is only allowed twice a week, in accordance with a schedule. The schedule will be developed, dividing watering days by address. Mandatory Water Once a Week Maximum Plant watering is only allowed once a week, in accordance with a schedule. The schedule will be developed, dividing watering days by address. Mandatory No Automatic Irrigation Use of automatic irrigation systems is prohibited. Watering by hand, soaker, and/or drip irrigation is allowed. Mandatory No Irrigation Irrigation is prohibited. Mandatory No Lawn Watering Watering of lawns is prohibited. Mandatory Water Early or Late Watering between 8am and 7pm is prohibited, due to high evaporation. Mandatory No Pools and Hot Tubs Filling swimming pools and hot tubs is prohibited (include information about safety around empty pools/tubs). Mandatory No Pressure Washing Pressure washing is prohibited. Mandatory No Vehicle Washing Washing of vehicles is prohibited, unless at a location that recycles the water. Mandatory No Water Features (a) Use of non-recirculating decorative water features such as fountains is prohibited. Mandatory No Water Features (b) Use of decorative water features, including those that recirculate, is prohibited. Non-Residential N/A Conservation Message Employee Awareness Increase employee awareness about using water wisely and encourage their suggestions. N/A Conservation Message Efficient Fixtures Replace older toilet, faucets, and other plumbing fixtures with newer, more efficient models. N/A Conservation Message Towels on Request Ask hotels to provide new towels only on request. N/A Conservation Message Check Cooling Towers Check cooling towers for overflow and excessive blowdown. N/A Conservation Message Commercial Kitchen Equipment If buying new food steamers, dishwashers, or ice machines, select water-efficient models. 18 Voluntary Water on Request Serve water only on request, and then ask before refilling. Mandatory No Fire Line Testing Fire line testing within buildings is prohibited. C. Stage 2 – Voluntary If supply conditions worsen, the WSRP moves to the Voluntary Stage. This stage relies on the voluntary cooperation and support of customers to meet target consumption goals. During the Voluntary Stage, specific voluntary actions are suggested for residential and commercial customers. The suggested customer actions are a combination of standard conservation practices (e.g. avoid watering mid-day) and curtailments that require customers to reduce their water use, which may result in sacrifice (e.g. take a shorter shower). The level of that sacrifice will depend on the severity of the water shortage. Triggers The “Voluntary Stage” will be implemented when one or both of the following factors applies: 1. Supply conditions have not improved, or have worsened. 2. Demand levels need to be reduced. Objectives • Achieve the demand reduction goal by voluntary customer action, as well as by utility actions. • Stretch available supply through supply management actions. • Prepare for potentially moving to the Mandatory Stage. Stage Activation The authority to enter the Voluntary lies with the City’s Public Works Administrator. This is the case whether entering the Voluntary Stage is done as the initial activation of the WSRP or as a progressive step if the WSRP is activated at a lower stage. Demand Reduction Goal Set Demand Reduction Goal based on supply conditions and demand reduction potential and, if appropriate, consistent with neighboring utilities and SPU. Key Public Messages • Moving to Voluntary: We are moving to the second stage of our WSRP, the Voluntary Stage, because our supply conditions have worsened. • Meet Demand Reduction Goal: We are asking customers to voluntarily reduce their water use to meet the demand reduction goal. • Customers Choose Methods: How customers achieve reduction is up to them. A full list of options will be available on the Water Utility’s website, with links to additional information from SPU at www.savingwater.org. • Top Suggestions: Top suggestions include: (to be determined in the previous stage; e.g. let your lawn go dormant and limit plant watering to twice a week, assuming shortage is during irrigation season). 19 • Cooperation Lessens Possibility of Mandatory Restrictions: If everyone cooperates, we may avoid moving to the Mandatory Stage where specific water use restrictions are mandated. Coordination and Communication Actions • Wholesale Customers: Update wholesale customers about current water supply conditions and that the Voluntary Stage has been formally triggered. Note that in the Advisory Stage, wholesale customers would have been involved in planning for the potential of moving to the Voluntary Stage. The City will give wholesale customers advance notice of the intent to formally move to the Voluntary Stage, so wholesale customers can do final preparations (e.g. get their website ready). The advance notice will likely be short in order to reduce the risk of unintended leaks to the press, which would complicate the process. Request continued cooperation, as identified under the Wholesale Customer Actions section. • Customer Inquiries: Establish a regular communication mechanism to keep department employees up to date on goals, conditions, and actions. • Revenue: Assess revenue implications and potential remedies, including reprioritizing expenses. • City Legislation: Request Council to adopt legislation on water use restrictions, enforcement, and any surcharges, if anticipate needing for Mandatory Stage and not already in place. • Seattle Public Utilities: Implement coordination with SPU on goals and outreach for Voluntary Stage if shortage is related to SPU water. • Outreach: Implement communication and outreach plan elements developed for Voluntary Stage. Also, develop the elements (including any exemptions enforcement) for the Mandatory Stage. o Provide recommendations for customer actions to reduce consumption. Encourage customers to visit the Water Utility website for more details on reducing water use. If the shortage is SPU-related, publicize the SPU water supply conditions webpage, which is updated regularly. o Develop and initiate a strategic public information, media, and advertising campaign appropriate to the severity of the problem and the goal for demand reductions. This could include publishing consumption information in daily newspapers to communicate the goal and ways to reduce consumption. o Establish routine timing for press releases that provide current status and outlook; present information in standardized format that becomes familiar to media and public. o Include drinking water quality information in public information so that if flushing is necessary, the public understands that it is essential for drinking water quality maintenance. o Establish regular communication mechanism to keep City employees up to date on goals, conditions, and actions, especially utility account representatives that are tracking costs associated with the water shortage. o Respond to customer correspondence regarding the shortage as quickly as possible and acknowledge receipt of correspondence if information is not readily available. 20 City Department Actions Require that City departments reduce their water use. The specific actions requested for this stage will be determined during implementation of the WSRP, however likely actions include the following (if not already implemented under the Voluntary Stage): • All Departments: o Establish a regular communication mechanism to keep department employees up to date on goals, conditions, and actions. o Let City-owned lawns go dormant and limit plant watering to twice a week. Avoid mid-day watering. Post explanatory signage if these recommendations cannot be implemented. Certain exemptions will apply. o Wash fleet vehicles only if using facilities that recycle the water. o Do not wash plazas, foyers, sidewalks, etc. with a hose. Use a broom instead. Certain exemptions will apply where necessary for health and safety. o Any applicable actions requested of general retail customers. o Turn off decorative fountains. o Post signage throughout buildings to encourage City employees (and the public where applicable) to reduce their water use. • Water Utility Department o Suspend meter testing. o Accelerate schedule to fix distribution system leaks. o Eliminate all operating system water uses determined to be non-essential to maintain drinking water quality such as pipeline flushing and reservoir overflows. Complete cleaning of any reservoirs only as needed. • Parks: Work directly with Parks department to implement feasible demand reduction actions. • Transportation: Suspend street washing. • Hydrant Permits: Restrict new hydrant permits for temporary water service to essential purposes. Water Quality and Supply Management Actions • Data Collection: Continue increasing data collection and monitoring of weather forecasts. • Modeling: Continue increased computer modeling runs of projected supply, storage, demand, and revenue scenarios. • Flushing: If necessary, implement flushing to maintain water quality. Include flushing information in public communication and outreach so the public understands it is essential for drinking water quality. • Emergency Supplies: Ready emergency supplies for use and activate if appropriate. • Interties: Investigate using existing interties to increase supply availability and activate if appropriate. Retail Customer Demand Actions • Implement the Voluntary Stage customer demand reduction actions (that were determined in the Advisory Stage). 21 • Determine the list of customer demand reduction actions that would be requested if the WSRP advances to the Mandatory Stage. A list of potential actions customers can take to reduce water use is provided in Table 2. The actual actions selected for use will depend on the severity, likely duration, and timing of the shortage, as well as the demand reduction needed. Appendix B includes possible exemptions to water use restrictions for the City to consider in creating actual exemptions at the time of the event. Finally, determine appropriate enforcement strategies. Wholesale Customer Actions (Skyway): • Move to Next Stage: Implement the Voluntary Stage of their WSRP, consistent with City and, potentially, SPU. • Plan for Mandatory: Plan for the potential move to the Mandatory Stage. • Flushing: Assess current water main flushing and reservoir cleaning activities to determine whether they should be accelerated to be completed prior to the peak season or reduced to conserve supply. • Alternative Sources: Activate alternative supply sources, if appropriate. D. Stage 3 – Mandatory If the Voluntary Stage does not produce needed water use reductions, or if supply conditions worsen, the Mandatory Stage would be implemented. This stage prohibits or limits certain actions, which may be accompanied by an enforcement plan, which could include fines for repeated violations, as well as exemptions. The customer actions in this stage reflect a more aggressive approach that requires deeper levels of customer sacrifice (e.g. restricting irrigation). This stage may also include rate surcharges, although careful consideration would be required of the impacts of those charges. Triggers The “Mandatory Stage” will be implemented when one or both of the following factors applies: 1. Supply conditions have not improved, or have worsened. 2. Demand levels need to be further reduced. Objectives • Achieve the demand reduction goals by restricting specific water uses. • Further stretch available supply through additional supply management actions. • Prepare for potentially moving into the Emergency Stage. Stage Activation The authority to enter the Mandatory Stage lies with the Council. This is the case whether entering the Mandatory Stage is done at the initial activation of the WSRP or as a progressive step if the WSRP is activated at a lower stage. Demand Reduction Goal Set Demand Reduction Goal based on supply conditions and demand reduction potential consistent with water use restrictions and, if appropriate, adjust with neighboring utilities and SPU. Key Public Messages 22 • Moving to Mandatory: We are moving to the third stage of our WSRP, the Mandatory Stage, because our supply situation has worsened and/or the voluntary approach in the previous stage has not resulted in the necessary demand reduction. • Mandatory Water Restrictions: It is necessary to impose mandatory restrictions on certain water uses. Those restrictions are as follows: (to be determined in the previous stage). There are exemptions for the following: (to be determined in the previous stage). • Rate Surcharge: If applicable, the rate surcharge is as follows: (to be determined in the previous stage). Coordination and Communication Actions • Wholesale Customers: Update wholesale customers about current water supply conditions and that the Mandatory Stage has been formally triggered. Note that in the Voluntary Stage, wholesale customers would have been involved in planning for the potential of moving to the Mandatory Stage. The City will give wholesale customers advance notice of the intent to formally move to the Mandatory Stage, so wholesale customers can do final preparations (e.g. get their website ready). The advance notice will likely be short in order to reduce the risk of unintended leaks to the press, which would complicate the process. Request continued cooperation, as identified under the Wholesale Customer Actions section. • City Employees: Continue regular communication with department employees to keep them up to date on goals, conditions, and actions. • Customer Inquiries: Continue responding to customer inquiries, using the strategy established in the Voluntary Stage. Note that customer inquiries could show up in various ways, including social media, which may require a different strategic communication approach. • Revenue: Continue assessing revenue implications and potential remedies, including reprioritizing expenses. • City Legislation: Request Council to adopt legislation on water use restrictions, enforcement and any surcharges, if anticipate needing for the Emergency Stage and not already in place. • Seattle Public Utilities: Implement coordination with SPU on goals and outreach for Mandatory Stage, if shortage is related to SPU water. • Renton Regional Fire Authority: Request that the Renton Regional Fire Authority limits training exercises that use water. • Outreach: Implement communication and outreach plan elements developed for Mandatory Stage. Also, develop the elements for the Emergency Stage, if likely needed. We are experiencing a drought/shortage. We are asking everyone to help by… We have suggestions/requirements on how to reduce water use. Also see “Key Public Messages”. o Urge customers who irrigate with private wells, reclaimed, or recycled water to install signs to let the public know the type of water being used. 23 o Prohibit water waste including untended hoses without shut-off nozzles, obvious leaks, and water running to waste such as gutter flooding and sprinklers/irrigation whose spray pattern unnecessarily and significantly hits paved areas. o In communicating mandatory restrictions to the public, distinguish clearly between lawn/turf watering and watering gardens since lawns and turf can go dormant in the summer. The type and amount of watering allowed will need to be clearly defined. City Departments Actions: Require that City departments reduce their water use. The specific actions requested for this stage will be determined during implementation of the WSRP, however likely actions include the following (if not already implemented under the Voluntary Stage): • All Departments o Let lawns go dormant and limit plant watering to twice a week. Avoid mid-day watering. Post explanatory signage if these recommendations cannot be implemented. Certain exemptions will apply. o Wash fleet vehicles only if using facilities that recycle the water. o Do not wash plazas, foyers, sidewalks, etc. with a hose. Use a broom instead. Certain exemptions will apply where necessary for health and safety. o Any applicable actions required of general retail customers. o Turn off decorative fountains. o Post signage throughout buildings to encourage City employees (and the public where applicable) to reduce their water use. • Water Utility Department o Suspend meter testing. o Accelerate schedule to fix distribution system leaks. o Increase drinking water quality monitoring as necessary to ensure the water supply and demand management strategies will not result in unacceptable drinking water quality. • Parks: Work directly with Parks department to implement feasible demand reduction actions. • Transportation: Suspend street washing. • Hydrant Permits: Restrict new hydrant permits for temporary water service to essential purposes. Exemptions from Water Use Restrictions: Implement the exemptions for the Mandatory Stage water use restrictions. Determine appropriate exemptions for the Emergency Stage water use restrictions. Appendix B includes possible exemptions to water use restrictions for the City to consider in creating actual exemptions at the time of the event. Rate Surcharges: Consider implementing rate surcharges to accelerate customer compliance with the restrictions and/or recover lost revenue. Water Quality and Supply Management Actions • Data Collection: Continue increased data collection actions and monitoring of weather forecasts. 24 • Modeling: Continue increased City’s computer modeling runs of projected supply, storage, demand, and revenue scenarios. • Emergency Supplies: Activate emergency supplies, as appropriate. • Interties: Activate interties, if not already implemented. Retail Customer Demand Actions • Implement the Mandatory Stage customer demand reduction actions (that were determined in the Voluntary Stage). • Determine the list of customer demand reduction actions that would be requested if the WSRP advances to the Emergency Stage. A list of potential actions customers can take to reduce water use is provided in Table 2. The actual actions selected for use will depend on the severity, likely duration, and timing of the shortage, as well as the demand reduction needed. Wholesale Customer Actions (Skyway): • Move to Next Stage: Implement the Mandatory Stage of their WSRP, consistent with City and, potentially, SPU. • Plan for Emergency: Plan for the potential move to the Emergency Stage. • Enforcement: Enforce water use restrictions within their own service areas. • Flushing: Assess current water main flushing and reservoir cleaning activities to determine whether they should be accelerated to be completed prior to the peak season or reduced to conserve supply. • Alternative Sources: Activate alternative supply sources, if appropriate. E. Stage 4 – Emergency Curtailment At this stage, the City recognizes that a critical water situation exists and that, without additional significant curtailment actions, a shortage of water for public health and safety is imminent. This type of situation has never occurred in the City water system’s history. The stage is characterized by two basic approaches. First, increasingly stringent water use restrictions are established. Second, significant rate surcharges are used to increase customer compliance. A surcharge is a key component to the success of this stage. This would be the last stage used to address a progressive situation, such as a drought of increasing severity, or to respond to an immediate crisis, such as a major facility failure. Triggers The “Emergency Curtailment” stage will be implemented when any of the following factors apply: • Supply conditions have worsened. • Demand levels need to be further reduced. • The prospects of a water shortage are imminent if immediate action is not taken. Objectives • Achieve the demand reduction goals by additional restrictions on water use, recognizing that for this stage, customers’ lives and businesses may be significantly impacted. 25 • Stretch available supply through supply management actions. Stage Activation The authority to enter the Emergency Curtailment Stage lies with the Council, unless there is an immediate emergency, in which the City’s Mayor has the authority to enter this stage. Demand Reduction Goal Set Demand Reduction Goal based on supply conditions and demand reduction potential consistent with water use restrictions and, if appropriate, adjust with neighboring utilities and SPU. Key Public Messages • Moving to Emergency: We are moving to the final stage of our WSRP, the Emergency Stage, because our supply situation has worsened and/or the approach in the previous stage has not resulted in the necessary demand reduction. • Additional Water Restrictions: There are additional water restrictions as follows: (to be determined in the previous stage). There are exemptions for the following: (to be determined in the previous stage). • Rate Surcharge: If applicable, the rate surcharge is as follows: (to be determined in the previous stage). • Taste and Odor: If applicable, taste and odor water quality problems may occur with system-wide reduced water consumption. • Pressure Reduction: If applicable, pressure reduction problems may occur with system-wide reduced water consumption. Coordination and Communication Actions: • Formal Declaration of Emergency: The Council or Mayor declare a water supply emergency including instituting formal procedures for declaration. • Wholesale Customers: Update wholesale customers about current water supply conditions and that the Emergency Stage has been formally triggered. Note that in the Mandatory Stage, wholesale customers would have been involved in planning for the potential of moving to the Emergency Stage. The City will give wholesale customers advance notice of the intent to formally move to the Emergency Stage, so wholesale customers can do final preparations (e.g. get their website ready). The advance notice will likely be short in order to reduce the risk of unintended leaks to the press, which would complicate the process. • City Employees: Continue regular communication with department employees to keep them up to date on goals, conditions, and actions. • Customer Inquiries: Continue responding to customer inquiries, using the strategy established in the Voluntary Stage. Note that customer inquiries show up in various ways, including social media, which may require a different strategic communication approach. • Revenue: Continue assessing revenue implications and potential remedies, including reprioritizing expenses. 26 • Police and Fire Enforcement: Coordinate with police and Renton Regional Fire Authority requesting their assistance in promoting and enforcing emergency water restrictions. • Seattle Public Utilities: Implement coordination with SPU on goals and outreach for Emergency Stage, if shortage is related to SPU water. • Outreach: Implement communication and outreach plan elements developed for Emergency Stage. Include: We are experiencing a drought/shortage. We are asking everyone to help by… We have suggestions/requirements on how to reduce water use. Also see “Key Public Messages”. City Department Actions: Require that City departments reduce their water use. The specific actions requested for this stage will be determined during implementation of the WSRP, however likely actions include the following (if not already implemented under the Voluntary Stage): o Continue letting lawns go dormant and limit plant watering to twice a week. Continue avoiding mid-day watering. Post explanatory signage if these recommendations cannot be implemented. Certain exemptions will apply. o Suspend all washing of fleet vehicles. o Continue not washing plazas, foyers, sidewalks, etc. with a hose. Use a broom instead. Certain exemptions will apply where necessary for health and safety. o Continue keeping decorative fountains off. o Continue using signage throughout buildings to encourage City employees (and the public where applicable) to reduce their water use. • Water Utility Department o Continue to suspend meter testing. o Continue to accelerate schedule to fix distribution system leaks. • Parks: Prohibit all lawn and sport field watering. • Transportation: Continue suspension of street washing. • Exemptions from Water Use Restrictions: Implement the exemptions for the Emergency Stage water use restrictions. Appendix B includes possible exemptions to water use restrictions for the City to consider in creating actual exemptions at the time of the event. • Rate Surcharges: Consider implementing rate surcharges to accelerate customer compliance with the restrictions and/or recover lost revenue, as authorized by the Public Works Administrator. • Hydrant Permits: Restrict all hydrant permits to essential purposes. Water Quality and Supply Management Actions • Data Collection: Continue increased data collection actions and monitoring of weather forecasts. • Modeling: Continue increased City’s computer modeling runs of projected supply, storage, demand, and revenue scenarios. • Emergency Supplies: Activate emergency supplies, as appropriate. 27 • Interties: Activate interties, if not already implemented. Retail Customer Demand Actions • Implement the Emergency Stage customer demand reduction actions (that were determined in the Mandatory Stage). Wholesale Customer Actions (Skyway): • Move to Next Stage: Implement the Emergency Stage of their WSRP, consistent with City and, potentially, SPU. • Enforcement: Continue to enforce water use restrictions within their own service areas. • Flushing: Assess current water main flushing and reservoir cleaning activities to determine whether they should be accelerated to be completed prior to the peak season or reduced to conserve supply. • Alternative Sources: Activate supply sources, if appropriate. 28 IV.IMPLEMENTATION FOR AN IMMEDIATE CRISIS A. Background This section focuses on implementing the WSRP when an event, such as a system failure, hinders the City’s ability to supply enough water to meet customer demands, and requires immediate action. Implementing the WSRP under these circumstances has both differences and similarities from implementation for a progressive event such as a drought. Implementation of the WSRP for an immediate crisis is different in the following ways: • Lack of Preparation Time: In a typical progressive event, the City has weeks or months to prepare for action. In an immediate crisis, there is typically little to no preparation time and the City takes action within minutes, hours, and/or days. • Initial Stage: In a typical progressive event, the WSRP is activated at the Advisory Stage and progresses sequentially through stages as necessary. In an immediate crisis, the WSRP is activated at one of the more aggressive stages, likely either the mandatory or emergency stage. • Larger Volume: The volume of the water shortage for an immediate crisis could be more significant, thereby requiring larger-scale demand reductions. • Localized: The immediate crisis could be localized, thereby requiring demand reduction for only a limited geographic area. • Heightened Public Health and Safety: The need to protect water quality and availability to support public health and safety are heightened, including issues such as minimizing any outages and having sufficient water and pressure for firefighting. • City Emergency Response Plans: Implementation of the WSRP would likely join with implementation of other higher-level and/or more specific City emergency response plans. The City has broader, all- hazards plans that describe how their emergency management system is organized and managed in order to prepare for, prevent, mitigate, respond to, and recover from emergencies. The City has hazard-specific (e.g., earthquake) emergency response plans that might be applicable. • Incident Command System: The response would most likely be implemented under an Incident Command System (ICS), which is a nationally-sanctioned, standardized approach to the command, control, and coordination of emergency response. ICS is integral to the City emergency response plans. Implementation of the WSRP for an immediate crisis is similar to that of a progressive event in many considerations and principles including flexibility, sharing the burden of the shortage, and the importance of addressing financial implications. There are numerous crisis situations that could necessitate implementing the WSRP. Several examples are described below. The need to activate the WSRP would depend on the amount of the supply impacted, the amount of time needed to restore the system to normal functions, how easily water could be rerouted to customers in the affected area, and the amount of water being used by customers given the season. 29 • Cedar Valley Aquifer: Most of Renton’s drinking water is pumped from five wells that draw from a shallow aquifer, only 23 feet below land surface in some areas. o Contamination: Chemicals that spill on the ground travel through the soil, sand, and gravel and can pollute the aquifer. Because Renton’s aquifer is so shallow, it is particularly susceptible to pollution. With such a heavy reliance on the water produced by the Cedar Valley Aquifer, contamination of this resource would require activation of the WSRP in an immediate crisis mode. o Loss of Access to Aquifer: In the event of a natural disaster, infrastructure malfunction, or other incident leading to failure of the City’s main drinking water wells, access to the aquifer may be cut off. With such a heavy reliance on the water produced by the Cedar Valley Aquifer, loss of this resource would require activation of the WSRP in an immediate crisis mode. • Major Transmission Pipeline Break: A major transmission pipeline break, in the Renton or SPU system, could require activation of the WSRP in an immediate crisis mode. • Temporary Treatment Plant Shut Down: A temporary unplanned shut down of a major water treatment plant, in the Renton or SPU system, could require activation of the WSRP in an immediate crisis mode. B. Components The following nine components are discussed below. These are the same components as Section 3, Implementation for a Progressive Event, and the content is a hybrid of information from all four stages in Section 3. Therefore, while a stage is declared when implementing the WSRP for an immediate crisis, that stage may look slightly different than under a progressive event. 1. Triggers – Describes the general, qualitative conditions that would trigger the stage. 2. Objectives – Describes the overall objective of the stage. 3. Stage Activation – Describes who has the authority to enter the stage. 4. Demand Reduction Goal – Discusses the general, qualitative nature of the goal for the stage. 5. Key Public Messages – Describes the key public messages for the stage. 6. Coordination and Communication Actions – Describes a variety of work necessary to coordinate and communicate with key stakeholders such as: wholesale customers, SPU, Ecology, DOH, natural resource agencies, tribes, City employees, the general public, etc. The overall work will likely be led by the ICS Incident Commander, who makes assignments as appropriate. 7. Water Quality and Supply Management Actions – Describes work necessary to safeguard water quality and to maximize supply. 8. Retail Customer Demand Actions – Describes work necessary to reduce customer demand. 9. Wholesale Customer Actions (Skyway) - Describes actions required by each wholesale customer. 30 Triggers The appropriate stage (Voluntary, Mandatory, or Emergency) will be implemented when an event occurs that would prevent the City from supplying enough water to meet customer demands and requires immediate action. The selection of the appropriate stage will be based on the severity of the shortage. Objectives • Maximize the amount of water delivered to customers and restore full supply capabilities as soon as possible. • Achieve the demand reduction goals by voluntary or mandatory customer action. If activated at the Emergency Stage, restrictions may significantly impact customers’ lives and businesses. • Prepare for potentially moving to the next aggressive stage, if not already in the Emergency Stage. Stage Activation The authority to declare a water supply emergency and activate the WSRP for an immediate crisis lies with the Mayor. Demand Reduction Goal Set demand reduction goal based on supply conditions and demand reduction potential consistent with any water use restrictions. Key Public Messages • Activated WSRP: We have activated the WSRP due to an immediate crisis. The details of the crisis are as follows (to be developed at the time of the crisis). • Meet Demand Reduction Goal: We are asking customers to reduce their water use to meet the demand reduction goal. • Mandatory Water Restrictions (if activating at the Mandatory or Emergency Stage): It is necessary to impose mandatory restrictions on certain water uses. Those restrictions are as follows: (to be determined at the time of the crisis). There are exemptions for the following: (to be determined at the time of the crisis). • Rate Surcharge: If applicable, the rate surcharge is as follows: (to be determined at the time of the crisis). • Water Quality: If applicable, customers may find taste, odor or discolored water issues with their water due to changes in water supply operations (be more specific if appropriate). While the water may not be pleasing, it is safe to drink. • Pressure Reduction: If applicable, customers may experience a loss of pressure due to system operations. Customers with no water should call the City at: (contact to be determined at time of the crisis). 31 Coordination and Communication Actions • Formal Declaration of Water Supply Emergency: Depending on the event, the City’s Public Works Administrator, City Council, or Mayor make formal declarations of emergencies and activation of the WSRP. • Incident Commander and Team: Identify the Incident Commander and the team members. • Wholesale Customers: Inform wholesale customers about the crisis and that the WSRP has been activated. Request their cooperation, as identified under the Wholesale Customer Actions section. • DOH: Inform the DOH about the crisis and the activation of the WSRP. • Public Agencies: Coordinate with other City departments and public agencies (e.g., county, state and federal resource agencies, tribes, and other regional water suppliers) as appropriate. • Seattle Public Utilities: Implement coordination with SPU on goals and outreach for Emergency Stage, if shortage is related to SPU water. • Outreach: Develop and implement the initial communication and outreach plan. As described in the Communication and Outreach Framework in Appendix C, the WSRP should include the overall purpose, goals, audiences, and tools (e.g., FAQs, press releases, tips flyers). Additional outreach tools such as highway message boards, social media, or dial out phone systems might be used in an immediate crisis. • City Employees: Establish a regular communication mechanism to keep Water Utility employees up to date on goals, conditions, and actions. • Customer Inquiries: Establish one point of contact for responding to customer inquiries. • Revenue: Assess revenue implications and potential remedies, including reprioritizing expenses. • City Legislation: Request Council to adopt legislation on water use restrictions, enforcement and any surcharges, if anticipate needing and not already in place. • Renton Regional Fire Authority: Request that the Renton Regional Fire Authority either limit or suspend training exercises that use water, depending on the severity of the crisis. City Departments Actions Request that City departments reduce their water use in affected areas. The specific actions requested will be determined during implementation of the WSRP, however likely actions include the following: • All Departments: o Post signage throughout buildings to encourage City employees (and the public where applicable) to reduce their water use. o Let lawns go dormant and limit plant watering to twice a week. Avoid mid-day watering. Post explanatory signage if these recommendations cannot be implemented. Certain exemptions will apply. o Either wash fleet vehicles only if using facilities that recycle the water or suspend all washing of fleet vehicles, depending on the severity of the crisis. 32 o Do not wash plazas, foyers, sidewalks, etc. with a hose. Use a broom instead. Certain exemptions will apply where necessary for health and safety. o Turn off decorative fountains. o Any applicable actions requested of general retail customers. • Water Utility: o Suspend water main flushing and reservoir cleaning unless needed to support restoration to normal operations. o Suspend meter testing. • Police: Coordinate with police department requesting their assistance in promoting and enforcing any water restrictions, if entering the Emergency Stage. • Parks: Request that the Parks and Recreation Department reduce water usage. • Transportation: Suspend street washing. • Hydrant Permits: New hydrant permits for temporary water service will be either restricted to essential services or rescinded (unless necessary for public health), depending on the severity of the crisis. • Rate Surcharges: Consider implementing rate surcharges to accelerate customer compliance with the restrictions and/or recover lost revenue. Water Quality and Supply Management Actions • Maximize Supplies: Make system operational changes as needed to maximize the amount of water delivered to customers and restore system to normal operations. • Additional Wells: Ready the alternative supply (Maplewood Wellfield) and emergency production wells (Wells EW-3R and PW-5A), if available, and commence pumping when current well production is no longer sufficient. • Interties: The City has seven supply interties with SPU and three emergency interties with other neighboring water systems. Investigate using existing interties to increase supply availability and activate if appropriate. • Water Quality: Assess water quality in the distribution system to identify areas that may experience degradation with reduced consumption or changes to system operations. Increase monitoring if appropriate. Retail Customer Demand Actions Determine and implement the list of customer demand reduction actions requested/required. A list of potential actions customers can take to reduce water use are provided in Table 2. The actual actions selected will depend on the severity, likely duration, and timing of the shortage, as well as the demand reduction needed. Additionally, establish and implement appropriate exemptions. Appendix B includes possible exemptions to water use restrictions for the City to consider. Finally, determine appropriate enforcement strategies, if appropriate. 33 Wholesale Customer Actions (Skyway) • Activate Plans: Activate their own WSRPs, in a manner consistent with the City and, potentially, SPU. • Alternative Sources: Activate alternative supply sources, if appropriate and necessary. • Flushing: Assess current water main flushing and reservoir cleaning activities to determine whether they should be suspended. • Enforcement: Enforce any water use restrictions within their own service areas. 34 35 Appendix A of Appendix O UTILITY CUSTOMER OUTREACH CHECKLIST 36 37 Utility Customer Outreach Checklist This checklist is intended to be used by every utility that is a wholesale customer of Seattle Public Utilities (SPU) during implementation of SPU’s Water Shortage Contingency Plan. The checklist differentiates between actions that SPU will perform on behalf of its wholesale customers and actions that each individual utility is responsible for. If the water shortage is only related to Renton’s water supply, it would be expected that wholesale customers, such as Skyway, follow the suggestions under “Expected by Each Utility” and “Suggested for Each Utility”. Check Box Customer Outreach Action SPU Does for the Region Statewide Actions and Messaging: Coordinate with Ecology, DOH, and the Governor’s Office. Tri-County Actions and Messaging: Coordinate with Tacoma and Everett, as needed. Seattle Water Supply System Actions and Messaging: Lead coordination of the Operating Board and the Conservation Technical Forum. Regional Press Release: Issue regional press releases to major media outlets (and conduct subsequent media interviews). Regional Traditional Media: Purchase regional traditional media ads such as TV, radio, print, as appropriate. Regional Drought Website: Host a website to serve as the main drought website. This would likely be www.savingwater.org with a link to the SPU Water Supply page. Tips Flyer – Create: Create a flyer that helps customers: 1) understand there is a shortage situation and 2) understand ways to reduce their water use. Landscaping Community: Outreach to key landscaping community contacts including nurseries, industry organizations (WALP, WSNLA), the Garden Hotline, and parks/recreation departments. For contacts that are in wholesale customers’ service areas, SPU will coordinate the outreach with the appropriate wholesale customer. Expected by Each Utility Utility Websites: Post drought information prominently on the utility’s homepage and link to the regional drought website. Tips Flyer – Utilize: Make the tips flyer readily available (e.g. on utility website, in utility lobby, distribute in public areas such as community centers, libraries, etc.). Utility Bill/Insert/Newsletter: Include drought messages in existing utility “publications” such as bills, bill inserts, newsletter, etc. Social Media: Include drought messages in any social media vehicles used by the utility. Signage: Post signage in appropriate locations (e.g. at utility buildings, on utility vehicles, in key locations in service area). Brief Staff: Brief utility staff regarding the drought, using the SPU-produced FAQ as one tool. Events: Highlight the drought message at any community events the utility is participating in. Suggested for Each Utility Key Customers: Contact key customers directly (e.g. large water users, significant irrigators, highest billing tier, etc.). Local Press Release: Issue press releases to local media outlets (and conduct subsequent media interviews). On-Hold Message: Put a drought message on the telephone “on hold” messages for customers. Email Signature Line: Add a drought message in the email signature for utility staff. 38 39 Appendix B of Appendix O POTENTIAL EXEMPTIONS FOR WATER USE RESTRICTIONS 40 41 Potential Exemptions for Water Use Restrictions This document provides a framework for developing and implementing exemptions to customer water use restrictions that are part of the Mandatory and Emergency stages of the WSRP. Background Water use restrictions are key components of the Mandatory and Emergency Stages of the WSRP. For some water use restrictions, exemptions for continued water use may be appropriate. Exemptions can be useful in balancing the need to reduce overall water demand with minimizing hardships imposed on customers and certain industries, as well as protecting health and safety. For example, in the Mandatory stage, the City may prohibit irrigation for established plants, while allowing irrigation for newly planted landscapes because of their need for water to survive their establishment period. As described previously, the WSRP does not pre-identify specific demand reduction actions for each stage. Rather a list of potential actions customers can take to reduce water use is provided at the end of each stage description. The actual actions requested or required for each stage will depend on the severity, likely duration, and timing of the shortage, as well as the demand reduction needed. Similarly, the exact exemptions for the water use restrictions eventually selected for implementation in the Mandatory and Emergency Stages are not pre-identified. Rather this document provides a framework to be used during each implementation of the WSRP for how to develop and implement the restrictions. Potential Exemptions: Potential exemptions that should be considered include, but are not limited to, the following: • Irrigation: o Newly planted landscapes. Plantings completed after restrictions are announced are not eligible unless done as part of a capital project and necessary for a functional purpose such as slope stabilization. o Sports fields. These areas contribute to physical and psychological benefits of children and adults, and can be dangerous if not kept watered. o Golf course tees and green. Restrictions may apply to the fairways. o High traffic turf in City parks. o Trees. They cannot be quickly or inexpensively replaced. o Plant nurseries and garden centers. o Food crops. o Disabled gardeners who cannot hand water. Applicable to prohibition of automatic systems. Likely do not publicize. • Vehicle Washing: o Vehicle washing at commercial car washing facilities. • Pressure Washing o Pressure washing necessary to protect public health and safety such as washing downtown parks/sidewalks to clear trash, food, and human waste. Not exempt for aesthetic purposes. o Pressure washing that is part of scheduled building rehabilitations, such as preparing a surface for painting. 42 • Hose Washing o Hose washing necessary to protect public health and safety such as washing downtown parks/sidewalks to clear trash, food, and human waste. Not exempt for aesthetic purposes. • Swimming Pools and Hot Tubs o Health care facilities such as hospital physical therapy pools. o Commercial businesses where swimming pools or hot tubs are central to their business and shutting them down would have a significant negative financial impact. • Construction o Use of water for dust control in construction areas when necessary for compliance with air quality requirements. • Fire Line Testing o Testing necessary to protect public health and safety. • Private Wells/Reclaimed Water o Any use of water that is not from the public water system but is from private wells or reclaimed water. The City does not have the authority to restrict use of these sources, but could encourage users to post signs to indicate that alternative sources of water are being used. Development Process: The recommended process to develop and implement the exemptions is as follows: • Once the water use restrictions have been determined, develop any associated exemptions. The development of the exemptions should include input from the impacted parties. • Decide whether each exemption will require pre-approval by the City Council. • Develop the process and system necessary for processing exemption requests. o Customer contacts the City Need to determine City contact. Need to determine submission method (e.g. email, phone, or website). Need to determine submission contents (e.g. name, address of water use, water account number, description of how they fit the exemption, any required proof). o Enter request into tracking system Need to develop tracking system (e.g. Excel spreadsheet). o Determine whether request qualifies or not Need to set criteria to be considered for qualifying exemptions, with some discretion on behalf of the City (e.g. undue financial hardship, public health and safety, etc.). Need to determine who can authorize exemptions. o Notify customer of result Need to determine notification method (e.g. email, phone, or website). Need to determine whether customer will be required to post notice of exemption from the City. • Publicize the exemptions and the process to request an exemption when the restrictions are announced, including noting that exemptions may be revoked if the water supply situation worsens. 43 Appendix C COMMUNICATION AND OUTREACH PLAN FRAMEWORK 44 45 Communication and Outreach Plan Framework This document is intended to provide a framework for communication and outreach efforts during implementation of the WSRP. The actual Communication and Outreach Plan (COP) will be developed during implementation of the WSRP. The initial COP will be developed in the Advisory Stage, during which the City plans for the potential of moving into the Voluntary Stage. The COP will be modified as implementation of the WSRP continues, especially if the City moves into the Mandatory and/or Emergency Stage. The COP should include the following elements: overall purpose, goals, audience, and tools. More information on each of these elements is provided further below. The following steps should be used to develop the COP: 1. Confirm/modify the overall purpose. 2. Confirm/modify the goals. 3. Identify which audiences to target and/or to prioritize. 4. Identify which tools to develop. 5. Match the audiences and the tools. 6. Identify staff responsible for developing the tools. 7. Identify staff responsible for implementing the communication/outreach. 8. Track the implementation. 9. Modify as necessary. Overall Purpose The overall purpose of the COP is to make sure everyone is aware of the "drought/shortage message", which consists of the following components: 1. We are experiencing a drought/shortage. 2. We are asking everyone to help by…….(to be determined for appropriate WSRP stage). 3. We have suggestions/requirements on how to reduce water use. o Also see the “Key Public Messages” under each WSRP stage. Goals There are three goals of the COP, as follows: 1. Build awareness 2. Create a community presence 3. Targeted messaging Audiences There are a variety of audiences for the COP. Some audiences are broad in nature, while others are very specific. The seven main audiences, including locations/organizations/other subcategories, are as follows: 1. General Public • City of Renton community centers 46 • City of Renton library • Community events • Farmers markets • Multifamily property management associations • Churches 2. Irrigation Community • Area parks and recreation departments • Schools (if shortage occurs during the school year when irrigation of ballfields is most likely) • Local plant nurseries • Professional landscape/nursery organizations • Garden Hotline • Customers with particularly high use of irrigation water 3. Large Users (other than irrigation community) • Large consumers such as: i. King County South Plant ii. Skyway Wholesale iii. Boeing iv. Valley Medical Center v. G&K Services vi. Service Linen Supply 4. Business Community • Chambers of commerce • Business improvement districts • Commercial building operator associations • Hotel and restaurant association(s) 5. Environmental Community 6. Non-English Speakers 7. City of Renton Employees Tools There are a variety of tools that can be used for the COP. Tools considered for WSRP implementation are show below. The list includes both paid and “earned” media. Note that tools may change over time, especially as changes occur in technology and customers’ preferences. 1. 4-Stages infographic 2. City websites 47 3. Tips/restrictions flyer 4. Regular utility publication (bills, bill inserts, newsletters, etc) 5. Press release 6. FAQ 7. Advertisements (newspaper, television, radio, etc) 8.

Table 2.1 presents a preliminary schedule for the data gathering and field testing, detailing the activities within each day. This will allow our team to start the model calibration as soon as possible following the calibration data gathering. The remainder of this plan details the data required for calibration and testing procedures for each portion of the calibration tests. 2.2 Model Update and Check 2.2.1 Model Update Carollo Engineers, Inc. (Carollo) will perform an overall check of the hydraulic model to verify that it is running correctly. Carollo assumes the model received from the City is up-to-date, matches the City’s geographic information system (GIS) data, and that no updates to pipes or other system geometric features are required. If nodes or pipes require a change in the hydraulic model, City staff will make the changes and provide Carollo with an updated model. Projected demands will be applied in the model based on meter locations and demand factors for each customer class. Projected demands for the largest customers will be applied directly to each customer location. The demands will include the current year for model calibration, as well as the projected 10-year and 20-year average day demand (ADD) and maximum day demand (MDD) for planning. Carollo will verify that the model is set up to be able to perform water age analysis in the future. 2.2.2 Model Check The model check process will involve several steps to ensure that the model is producing reasonable results. Carollo will run the model with existing demand conditions and check system stability. Possible adjustments include modifications to pipeline connectivity, operational controls, ground elevations, facility characteristics, and pump curves.

It is assumed that the operational strategy is replicated in the hydraulic model. It is assumed that the system controls provided in the latest hydraulic model correspond to the latest data. However, the operations of each pump station, reservoir, pressure reducing station and other valve structures will be checked as needed; for instance, if the model is unable to meet field results. 2.2.4 Transmission Main Connectivity Check Carollo will use the connectivity features of InfoWater to verify the connectivity of the transmission mains within the distribution system. Any problems found using the connectivity locators will be reviewed on a case-by-case basis by the hydraulic modeler to determine whether adjustments need to be made to the connectivity of the model. Output reports of pipe flow characteristics, such as headloss (feet per kilofeet (ft/kft)) and velocity (feet per second (ft/s)) will also be used to locate problem areas to be further reviewed by the hydraulic modeler to determine whether additional adjustments need to be made to the connectivity of the model. 2.2.5 System Pressures Check The model check will compare the model output to the typical pressures expected throughout the distribution system. This process will allow Carollo to locate major errors in model creation, elevations, or GIS connectivity, as well as changes that need to be made in how operational controls of the system should be implemented in the model. 2.3 Fire Flow Testing 2.3.1 Overview of Fire Flow Calibration Process Model calibration using fire flow tests is intended to develop a steady state calibrated hydraulic model by closely matching modeled water pressures to field pressures under similar demand and system operating conditions. The primary varied parameter for this calibration will be pipeline roughness coefficients and facility minor loss coefficients, although other parameters may be adjusted as calibration results are generated. The scope of work for the City’s Water System Plan Update includes fire flow tests at up to twenty (20) locations over a two week period. The fire flow tests will consist of one or two flowing hydrants and two pressure hydrants. These field tests will be simulated in the model to calibrate the model under steady state conditions. Pressure loggers will be used to measure static and residual pressure at the pressure hydrants and also deployed throughout the system during hydrant tests to better measure the system’s reaction to each fire flow. The fire flow tests will each stress the City’s distribution system by creating a differential between the hydraulic grade line (HGL) at the points of hydrant flow and the system HGL at neighboring hydrants. This HGL differential will increase the effect of the roughness coefficients on system losses. The model roughness coefficients will be adjusted to match model pressures to field pressures within an acceptable tolerance. As the model is adjusted to match system pressures, roughness and loss coefficients will be adjusted only within a tolerance of industry accepted roughness coefficient ranges. If the model is unable to match the calibration results without leaving the acceptable range of roughness coefficient values for a given pipeline CITY OF RENTON | WATER SYSTEM PLAN | TECHNICAL MEMORANDUM 2 2-6 | JUNE 2018 | DRAFT material and age, there may be cause for further investigation of a previously unknown field condition. Examples of such conditions, which typically arise during hydraulic model calibration, include closed pipelines, partially closed or malfunctioning valves, extreme corrosion within pipelines, connectivity and diameter errors in GIS/as-builts, and diurnal patterns of large water users. 2.3.2 Fire Flow Test Locations Carollo has selected 20 preliminary testing sites, which are shown on Figure 2.1. Each of the testing sites is shown in detail on an individual detail map (Appendix 2A and Appendix 2B). Pressure loggers will also be installed in the system during the fire hydrant tests. The system was divided into three (3) sections, as shown on Figure 1. Each section is anticipated to have approximately 15 pressure loggers installed to help understand system’s response to hydrant tests. The test sites have been selected for accessibility and also such that they create a good geographical coverage of the City’s entire distribution system. All tests involve 6-inch and 8-inch diameter pipelines and are located away from major transmission lines to increase the chance that a substantial pressure drop (> 10 pounds per square inch (psi)) is observed during the tests. The fire test sites were selected using the City’s updated hydraulic model water main database, however, the City should confirm the pipeline and fire hydrant information in the vicinity of each test site (e.g., alignment, diameter, age, and material of the pipelines and location of fire hydrants).

TECHNICAL MEMORANDUM 2 | WATER SYSTEM PLAN |CITY OF RENTON DRAFT | JUNE 2018 | 2-11 2.3.4 Standard Fire Flow Test Protocol 2.3.4.1 Required Equipment / Staff Required Staff A minimum of 5 people should be available during the hydrant flow testing for the following tasks: • Three (3) City staff members at the flowing hydrant(s). • Two (2) Carollo staff members at pressure hydrants. City staff shall be responsible for installation/removal of data loggers on hydrants, operation of valves, driving City vehicles or any other function involving City property. Required Equipment (City) • 3 pressure gauges (1 primary, 1 secondary, 1 spare). • 3 flow gauges and diffusers (1 primary, 1 secondary, 1 spare). • Dechlorinating equipment for the discharged water. • Signage and cones for traffic safety. • Sand bags as needed for control of discharged water. • 6 hand-held radios or push-to-talk type cell phones (1 per person and 1 spare). • Wrenches and equipment to open/flow each hydrant and necessary valves. • 5 Dickson pressure loggers. Required Equipment (Carollo) • Maps and field testing forms (including routing and order of testing). • Data collection sheets. • Means to pull data from pressure loggers. • 15 Dickson pressure loggers. 2.3.4.2 Fire Flow Testing Procedure 1. Calibrate Meters. On the day of fire flow testing, all the pressure and flow meters should be calibrated by comparing readings when attached to the same hydrant. 2. Take Positions. Position everyone at their respective locations with their clipboard and field-testing forms and confirm that everyone is at their place via radio/cell phone/hand signals. 3. Install Pressure Loggers. Attach the pressure loggers to the pressure hydrants (P-1 and P-2) and Flow hydrant (F-1). 4. Record Pre-flow Conditions: a. Carollo coordinator will log the time, date and location in the testing form. b. Carollo coordinator will record the static pressure reading from each hydrant, one-by-one (before opening the flowing hydrant), and record in the field testing form. 5. Install Flow Gauge. Attach the flow gauge to the flow hydrant (F-1). 6. Start Hydrant Flow. Carollo coordinator will have a City staff member open the flowing hydrant (F-1) until a steady stream is flowing (divert into gutters). 7. Confirm Pressure Drop Target is Met and Record Flow Conditions: a. Carollo coordinator will ask for the flow from the flowing hydrant (F-1) and record in the field testing form. CITY OF RENTON | WATER SYSTEM PLAN | TECHNICAL MEMORANDUM 2 2-12 | JUNE 2018 | DRAFT b. Carollo coordinator will obtain pressure drop from person at pressure hydrants (P-1 and P-2). c. Carollo coordinator will confirm that pressure is stabilized and at least 10 psi less than static pressure: i. If ΔP≥10 psi: go to next step. ii. If ΔP<10 psi: Carollo coordinator will ask person at flowing hydrant (F-1) to close the hydrant, repeat steps above with both flowing hydrants (F-1 and F-2). iii. If ΔP≥5 psi: go to next step (10 psi is preferred, but 5 psi is still acceptable). iv. If ΔP<5 psi: move to next site (test failed). 8. Close Flowing Hydrant. Carefully and slowly close the flowing hydrant. If two hydrants are flowing, close one at a time. 9. Check Results. Carollo coordinator will check for any anomalies (such as a gauge stuck on a high pressure or consistently showing significantly higher pressure than the rest of the readings). If results are irregular, repeat the test one more time. 10. Move to Next Site. If all looks good, Carollo coordinator will notify all field personnel to move on to the next hydrant flow test site. 2.3.5 Extended Period Calibration The extended period calibration (EPS) improves the model’s ability to simulate long-period operation of the system. The calibration is done by closely matching the model pressures, flows, and tank levels to field conditions over a 24-hour period of similar demand and system boundary conditions. Pressure data, tank levels, and flows from the water supplies, booster stations, and the pressure reducing stations will be recorded for several days in order to obtain EPS calibration data. The primary varied parameters for this calibration will be operational controls and pipeline roughness coefficients; although other parameters may also be adjusted as calibration results are generated. 2.3.5.1 Data Required for Extended Period Calibration The calibration data required for the extended period calibration consists of records of system pressures, tank levels, and flows from groundwater wells, interconnections, pump stations, and the pressure reducing stations throughout the distribution system. These system pressures will be gathered both by the City’s existing sensor network and by temporary pressure loggers, which will be attached to hydrants throughout the distribution system. Additional data, including system controls and operational details, will be required to establish boundary conditions for the model. This data will be gathered over the course of twenty-one (21) days between June 29, 2018 and July 20, 2018 (See Table 2.1 for the complete calibration schedule). A target system interval of 15 minutes will be used for data gathering. If any facilities listed lack the capabilities for 15 minute interval data gathering (e.g., they use circular charts or flow totalizers), assumptions will be necessary to interpolate data for the calibration. The calibration data required for EPS calibration is listed by site in Table 2.2. The location of the temporary pressure loggers are shown on Figure 2.2, and the respective hydrant number is listed on Table 2.3. See Appendix 2C for detailed temporary pressure logger site information.

Table 2.4 presents a sample format for the SCADA data. Depending on the interval of data available and record keeping capabilities of the SCADA system, modifications may need to be made to the SCADA system prior to the calibration week (and impacting the schedule). It would be preferable to our team to obtain SCADA data on 15-minute intervals. If the SCADA data is queried from each facility independently, the time of each data point should be included in the output report.

Manual Facilities For any manually operated facilities listed in Table 2.2 operated during the EPS data gathering period, an operational log should be substituted for the requested facility parameters. It is assumed that flow totalizers are used to take daily readings of the amount of water pumped during each 24-hour period. For any manually operated pump used during the extended period calibration week, the hours that the pump is on or off, along with the flow rate during each operation period will be needed. Photocopies of the log sheets for these pumps would be sufficient. If the City finds it more convenient, a handwritten or electronic log of all sites would also be sufficient. Temporary Pressure Loggers Carollo will provide 15 temporary pressure loggers to be attached to hydrants within the City’s distribution system. The City has 5 pressure loggers that can also be used for this field test. Our team has indicated hydrant locations for the 20 pressure loggers on Figure 2.2. City staff will install near these locations as local meters and appurtenances allow, tentatively between June 29, and July 20, 2018. 2.3.5.3 Required Equipment / Staff Required Staff (City) City employees will place all of the pressure loggers in the field one day prior the testing (tentatively June 29, 2018). City staff shall be responsible for installation/removal of data loggers on hydrants, driving City vehicles, or any other function involving City property. At the end of the testing (tentatively July 20, 2018), the City staff shall remove the loggers and Carollo will have a courier pick up the pressure loggers at Renton Shop. TECHNICAL MEMORANDUM 2 | WATER SYSTEM PLAN |CITY OF RENTON DRAFT | JUNE 2018 | 2-21 Required Equipment (City) • Appropriate wrenches and equipment to place loggers at each location. • 5 pressure loggers. Required Equipment (Carollo) • 15 pressure loggers – (C-30 through C-46). 2.3.5.4 Models and Intermediate Readings The sampling interval for all pressure loggers should be set to 5 minutes. Each pressure logger will require approximately 6,048 data points (12 data points per hour over 21 days). The internal capacity of the Dickson PR125 pressure loggers is limited to 60,000 data points, and the internal capacity of Track-IT 150 pressure loggers is limited to 64,000 data points, all of which are sufficient to record twenty-one days of data in 5-minute intervals.

Section 2 HYDRAULIC MODEL DEVELOPMENT The City provided its existing hydraulic computer model of the water distribution system to Carollo for use as part of the Water System Plan Update (Plan). The existing hydraulic model uses the InfoWater modeling software platform, developed by Innovyze. This section summarizes the procedures used to update the existing hydraulic model per the Plan Scope of Services. 2.1 Model Demands Water demands in the City’s existing hydraulic model were geocoded by the City based on customer AMI records for the year 2018. As part of the model update process, these demands were reviewed by pressure zone to verify the demand estimates provided in Chapter 3 of the Plan. 2.2 Operational Area Diurnal Patterns Custom diurnal patterns for both winter and summer demands were developed for each of the City’s five operational areas. The custom diurnal patterns are based on AMI data provided by the City for winter and summer periods in 2018 for each customer category and normalized so that the average of the hourly multipliers is equal to one. The diurnal patterns are then multiplied by the 24-hour average demands input at the model nodes for the planning scenario to simulate the normal daily demand variations that occur during a typical winter or summer demand condition. This provides operating data on how the tanks and pumps move water through the system. The diurnal patterns were developed using the hourly AMI data provided by the City in SQL format. The AMI usage data was analyzed using a combination of SQL Server, R, and Tableau. Figure 1 is a screenshot from R Studio illustrating examples of patterns developed by customer category. The rest of the patterns for each operational area and each customer category can be found in Attachment A of this Appendix document. CITY OF RENTON | APPENDIX Q – HYDRAULIC MODEL DEVELOPMENT AND CALIBRATION FEBRUARY 2020 | DRAFT Figure 1 Patterns Example Section 3 HYDRAULIC MODEL CALIBRATION The purpose of the water system hydraulic model is to estimate, or predict, how the water system will respond under a given set of demand conditions. One way to test the accuracy of the hydraulic model is to create a set of known conditions in the water system and then compare the results observed in the field against the results of the hydraulic model simulation using the same conditions. Two types of calibration were performed under this effort: • Extended Period Simulation (EPS) calibration. • Steady-state calibration. The EPS calibration uses the SCADA and pressure loggers data and compares pressure, flow, and tank levels at all of the City’s facilities during a representative 24-hour period. Flow tests conducted in the field on the water system are a standard method to verify the models accuracy and confirm the accuracy of the data used in the hydraulic model construction. Analysis of the flow test data also provides a greater understanding of how the water system operates. Field testing can indicate errors in the data used to develop the hydraulic model, or show that a condition might exist in the field not otherwise known. For example, valves, which are reported as being open, might actually be closed (or vice versa), an obstruction could exist in a pipeline, or pressure settings for a PRV may be slightly different than noted. APPENDIX Q – HYDRAULIC MODEL DEVELOPMENT AND CALIBRATION| CITY OF RENTON DRAFT | FEBRUARY 2020 Field testing can also correct erroneous model data such as incorrect pipe diameters or connections. Data obtained from the field tests can be used to determine appropriate roughness coefficients for mains, as roughness coefficients can vary with age and pipe material. 3.1 Model Calibration Overview and Methodology The model calibration consisted of two parts, a EPS calibration and a fire flow (hydrant) test calibration. This section describes both of the calibration steps. 3.1.1 EPS Calibration The initial calibration process consisted of a macro ou EPS calibration. Carollo ran the model under existing demand conditions in order to verify that the model forecasted pressures are reasonable and to make sure that the reservoirs were replenishing following peak hour demands. The macro calibration process included executing the following steps to ensure that the model produces reasonable results. • Transmission Main Connectivity. Carollo used the connectivity features of the hydraulic modeling software to verify the connectivity of the transmission and distribution mains within the distribution system. Proper connectivity verifies that there are no interruptions in the pipe connections. Possible issues found using the connectivity locators are reviewed on a case-by-case basis to determine whether adjustments needed to be made to the connectivity of the model. The model output reports on headloss (ft/kft) and velocity (ft/s) were also used to locate possible connectivity issues that required adjustment. • System Pressures. The macro calibration compared the model output to typical pressures of each pressure zone. This process allowed Carollo to verify that model facility size (pipe diameters and pump capacity), ground elevations, connectivity, and operational controls were reasonable. • Facility Characteristics. Hydraulic model results for the City’s wells, booster pump stations, and tanks were reviewed and compared to the City’s available SCADA data to verify that data input into the hydraulic model (e.g., pump curves, operational controls, PRV settings, etc.) produced results comparable to what the system experiences. The hydraulic model was run under existing conditions and results were compared to the SCADA data at all wells, booster pump stations, tanks, and pressure loggers. 3.1.2 Fire Flow Test Calibration The second step in model calibration after macro calibration is to compare model results to field pressures measured during a series of fire flow tests. This process is used to develop a calibrated hydraulic model by closely matching model simulated pressures to field pressures under similar demand and system boundary conditions. The model parameters that are adjusted during this process are primarily the pipeline roughness coefficients, although other parameters can also be adjusted as calibration results are generated. CITY OF RENTON | APPENDIX Q – HYDRAULIC MODEL DEVELOPMENT AND CALIBRATION FEBRUARY 2020 | DRAFT Hazen-Williams roughness coefficients, or C-factors, have industry accepted value ranges based on pipeline material, diameter, and age. Characteristics specific to the City’s water distribution system such as water quality, temperature, construction methodologies, material suppliers, and other factors may result in roughness coefficients that differ from the average of the industry accepted ranges. Fire flow calibration refines the value of roughness coefficients that best indicate the conditions of the City’s distribution system. During average day flows, roughness coefficients have a relatively small effect on the operation of the distribution system. However, as the flows increase in the system on higher demand days or during fire flows, velocity within pipelines increase and roughness coefficients contribute more to overall system headloss. Fire flow tests artificially create high demand events to generate more headloss, allowing a better estimation of the pipeline roughness coefficients. Fire flow tests stress the distribution system by creating a differential between the hydraulic grade line (HGL) at the point of hydrant flow and the system HGL at neighboring hydrants. This HGL differential increases the effect of the roughness coefficients on system losses and allows adjustments to the model to match model pressures to field pressures within an acceptable tolerance. As the model is adjusted to match system pressures, roughness coefficients should be adjusted only within a tolerance of industry accepted roughness coefficient ranges. If a model is unable to match the calibration results without leaving the acceptable range of roughness coefficient values for a given pipeline material and age, there may be cause for further investigation of a previously unknown field condition. Examples of such conditions, which typically arise during hydraulic model calibration, include closed valves, partially closed or malfunctioning valves, extreme corrosion within pipelines, connectivity and diameter errors, and diurnal patterns of large water users. The City performed hydrant flow tests as part of this project so that the most current data available could be utilized to update the model. The sites were selected so that each of the City’s pressure zones had at least one fire flow test and so that the locations were not near pump stations, valves, or storage facilities, if possible. Calibration Plans and testing locations are located in Appendix P Each fire test was conducted by first measuring static pressures at two “pressure” hydrants. Next, two “flowing” hydrants were opened to release a large amount of flow and to cause a significant headloss and pressure drop. With the flowing hydrants open, measurements were recorded to quantify the flow rate from each hydrant, and to determine the residual pressure of the two pressure hydrants. The City also provided SCADA data for the majority of major system facilities, including supply sources (i.e., wells, Springbrook Springs), tanks, and booster pump stations. SCADA data were not available for the City’s PRVs. Two model simulations, or scenarios, were created in the hydraulic model for each fire flow test. The first scenario was called the "static" run, which simulated the water system just prior to each test. The second scenario, referred to as the "residual" run, simulated the system during the test while the hydrants were flowing. A total of 20 tests were performed on the system and therefore a total of 40 computer simulations were created to calibrate the model. APPENDIX Q – HYDRAULIC MODEL DEVELOPMENT AND CALIBRATION| CITY OF RENTON DRAFT | FEBRUARY 2020 In both static and residual model scenarios, model demands were scaled up or down to represent the model demand during the fire flow test as reasonably as possible. Tank levels were also adjusted in each fire test scenario to match the actual tank levels recorded during the tests. In addition, the initial status of the City’s wells and booster pumps were modified so that they matched actual conditions (i.e., open or closed) recorded during the tests. The residual model scenarios are identical to the appropriate static model scenarios, except that fire flow demands were added to the appropriate nodes. 3.2 Model Calibration Results Numerous simulations were performed during the calibration phase. The model was run for a 24-hour representative period from the field testing period and modeled results were compared to field recorded data from SCADA and pressure loggers. For each facility, pressure, flow, and levels were compared. A total of 12 tanks, seven booster pump stations (BPS), eight wells and sources, and 20 loggers were used during calibration. Figure 2 shows an example of calibration results for the Highlands BPS; the rest of the calibration graphs can be found in Attachment B. Figure 2 EPS Calibration Example CITY OF RENTON | APPENDIX Q – HYDRAULIC MODEL DEVELOPMENT AND CALIBRATION FEBRUARY 2020 | DRAFT For several test locations, the hydrant tests were re-run to check system changes and verify test results. Adjustments were made to the model between runs to minimize the differences between the model and field results. A detailed summary of the calibration results is shown in Table 1. The table lists the results of each field test conducted and corresponding hydraulic model results. For the pressure hydrant tests, the results are considered acceptable if the model simulated pressures are within 10 ft (4.3 psi) difference to the field data. As shown in Figures 3 and 4, 90 percent of all static pressure are within the +/-4.3 psi, while 80 percent of the residual pressure are within +/-4.3 psi. Figure 3 Steady-State Static Pressure Calibration Results Summary APPENDIX Q – HYDRAULIC MODEL DEVELOPMENT AND CALIBRATION| CITY OF RENTON DRAFT | FEBRUARY 2020 Figure 4 Steady-State Residual Pressure Calibration Results Summary Section 4 SUMMARY For all of the facilities SCADA data and all fire flow tests performed by City staff, the model- simulated pressures, flows, and levels as compared to the corresponding field-measured metrics are in the good or very good range. The model is calibrated for the system as it is configured and operated in 2018. Therefore, the model is an appropriate tool for projecting future conditions.

It is recommended that the City install back‐up power generators at the Monroe Avenue BPS to allow storage to be provided from the Highlands 445 pressure zone to the Highlands 465 pressure zone (which will also improve pumping capacity for long‐term).

A few options are available to the City to mitigate the deficiency.• Construct a new 1.5 MG tank for the Rolling Hills 590 Operational Area. The new tank will replace the existing 0.3 MG tank.• Add back‐up power to the Maplewood BPS to increase pumping capacity from the Rolling Hills 490 Zone to the Rolling Hills 590 Zone, and add auto‐start, auto‐transfer, and back‐up power to the Rolling Hills BPS such that three pumps can be operated at the same time.7,700,000$ 10,700,000$ 3,210,000.00$ 3,477,500$ 17,395,000$ Construct a new 1.5 MG tank for the Rolling Hills 590 Operational Area.

The West Hill 495 storage deficiency is minimal (0.02 MG). The City currently operates the tank with a 16 feet operational band, which equates to a 0.22 MG operational storage volume (as shown on Table 7.10). It is recommended that the City slightly update operational strategy and tighten the operational band from 16 feet to 14 feet. This will allow to decrease operational volume and mitigate deficiency.0‐10 years‐$ ‐$ ‐$ ‐$ ‐$ $150,000 per yearAnnual150,000$ 3,000,000$ 3,000,000$ $100,000 per yearAnnual100,000$ 2,000,000$ 2,000,000$ 0‐10 years300,000$ 300,000$ 0‐10 years400,000$ 400,000$ Annual10,000$ 200,000$ 200,000$ $50,000 per yearAnnual50,000$ 1,000,000$ 1,000,000$ $100,000 per yearAnnual100,000$ 2,000,000$ 2,000,000$ Annual200,000$ 4,000,000$ 4,000,000$ $200,000 per yearAnnual200,000$ 4,000,000$ 4,000,000$ $200,000 a yearAnnual200,000$ 4,000,000$ 4,000,000$ $400,000 in 10 year and in 20 yearAnnual400,000$ 800,000$ 800,000$ APPENDICES | WATER SYSTEM PLAN UPDATE | CITY OF RENTON FINAL | MAY 2021 Appendix S CIP PRIORITIZATION Appendix S – Detailed Ranking Methodology As part of this Water System Plan (Plan), a high-level prioritization matrix was developed to help with prioritization and ranking of the projects identified in the Capital Improvement plan (CIP). The capital improvement implementation was separated into two phases: Short term: 0 to 10 years. Long term: 10 to 20 years. The City developed prioritization criteria to prioritize all projects and recommendations from this Plan between Short-term and Long-term. Short-term projects have already started or are committed to starting within a reasonable timeframe and include high-priority projects, such as the following: High priority multi-feature projects. Projects improving system reliability. Maintenance-identified projects. All other CIP projects, such as dead-end programs or single feature projects are long term. Table 1 summarizes the high-level prioritization matrix for different project types and purposes. Table ͭ Overall Prioritization Criteria Project Types(ͭ) ͬ‐ͭͬ years ͭͬ‐ͮͬ years Dead‐end pipes in existing non‐single family areas (ͯ,ͬͬͬ gpm): X Dead‐end pipes in existing single family areas (ͭ,ͬͬͬ gpm): X Maintenance projects X Pipe upsize due to excessive velocity (over ʹ ft/sec) X R&R pipes only – past RUL Annual replacement ͈ R&R pipes only – reaching RUL ͬ‐ͭͬ years R&R pipes only – reaching RUL ͭͬ‐ͮͬ years Pipe upsize for fire flow only X Pipe upsize for fire flow, maintenance, and past RUL X Pipe upsize for fire flow, and RUL reached in ͬ‐ͭͬ years X Pipe upsize for fire flow, and RUL reached in ͭͬ‐ͮͬ years X Pressure Zone projects (PZ‐ͬͮ) X Pump Station projects (PS‐ͬͭ, PS‐ͬͮ, PS‐ͬͯ) X Note: (ͭ) gpm – gallons per minute; RUL – remaining useful life. A detailed and customized scoring method using weighting factors was developed to help refine ranking and prioritizing specific pipeline projects from the general method above. Note, general repair and replacement program from the Remaining useful Life (RUL) analysis are done evaluated against the method below. The City identified five categories with different weighting factors each: 1. Pipe age 2. Pipe material 3. Pipe size 4. Pipe type 5. Project location The total score obtained by each pipeline once evaluated with the scores below is an indication of the priority to implement the project identified. Only specific projects developed during the system analysis using the hydraulic model and the specific projects identified by the City’s maintenance Shops were run through this prioritization and ranking methodology. Results are presented in Table 2.
