ES EXECUTIVE SUMMARY
ES.1 Introduction
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 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.

EXECUTIVE SUMMARY | WATER SYSTEM PLAN UPDATE | CITY OF RENTON
FINAL | MAY 2021 | ES-7
Mt. 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.

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.

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).

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.

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.

Rolling Hills 590 Recommendation
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 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.

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.

EXECUTIVE SUMMARY | WATER SYSTEM PLAN UPDATE | CITY OF RENTON
FINAL | MAY 2021 | ES-39
ES.10 Financial Program
The Water Utility’s financial status was evaluated as part of the Plan, which provides a cursory evaluation of its ability to finance the necessary capital improvements identified in the CIP. 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.

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 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.

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

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.

1.7 Existing Service Area Characteristics
The City’s service area boundaries are shown on Figure 1.3. 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.

2.2 Water System Description
Several changes to the City’s water system have occurred since the completion of the
2012 Water System Plan Update. 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.

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.

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

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.

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.

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).

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

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.

2.2.4 Booster Pump Stations
The City maintains and operates 12 pump stations that provide regular and emergency supply from lower pressure zones to the higher pressure zones. 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. The pressure in the Kennydale 320 PZ measured at the station.

(2) The current maximum capacity of the wellfield is 3,000-gpm and is limited by current installed treatment. Two of the 1,550-gpm pumps or one of the 2,400-gpm pumps may be operated at
one time based upon treatment limitations.
(3) Only one of the 3,500-gpm fire pumps can be run at one time. Preliminary (30 percent) design in 2018 for installing emergency generator and auto transfer switches and replacing the existing
fire pumps (two 3,500-gpm). Construction by ~ 2021.
(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.

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.

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.

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.

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.

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.

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.

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 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.

3.3.1 Historical Water Production
The City has a variety of supply sources, including Springbrook Springs, 10 production wells, and interties with SPU. 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.

3.3.1.2 Maximum Day Demand
Historical MDD values represent the largest amount of water produced in a single day in a given
year, usually during the summer when irrigation use is highest. 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.

3.3.2 Historical Customer Connections
From 2008 to 2017, the total number of the City’s retail water service connections increased
by 5.6 percent. 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).

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.

3.3.3.1 Largest Consumers
To more accurately predict the magnitude and location of future demands, the City’s six Largest Consumers' consumption was evaluated separately from other customer categories. 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.

3.3.3.2 Distribution System Leakage and Non-Revenue Water
DSL is water not authorized for consumption, and equals the total water produced/purchased minus the total authorized consumption. 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.

3.3.4 Seasonal Variations in Water Consumption
To better assess the City’s water use, Carollo also analyzed seasonal water use. 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.

3.3.5.1 Equivalent Residential Units
An ERU is the amount of water consumed by a typical full-time Single-Family Residence. 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.

3.4 Demographic Trends
To determine future demand for the City's retail water service area (RWSA), current and
projected demographic trends were developed using data provided by the PSRC. 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.

Using PSRC’s household and employment projections for each pressure zone, annual growth rates were calculated to forecast future City water connections for each customer category.
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.

Water connections were projected by raising the City’s existing number of water connections in each pressure zone by the growth rates in Table 3.13 and Table 3.14. Table 3.15 shows the
number of connection projections for the planning years, which will be then used to estimate the
City’s future water demand.

3.5 Water Demand Projections
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.
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.

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.

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.

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

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.

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.

3.5.3 ERU Projections
When converting projected number of accounts to ADD, the first step is to convert these number
of accounts into a number of ERUs. 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.

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.

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.

3.5.5 Summary
The City’s WUE program will 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 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.

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.

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.

Figure 4.3 presents monthly water production in 2017. 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.

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.

4.4.2 Current Conservation Program
4.4.2.1 Municipal Water Law
The MWL governs water conservation planning. 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.

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.”

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.

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.

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.

Chapter 5 POLICIES, CRITERIA AND STANDARDS
5.1 Introduction
The City of Renton (City) Water System Plan (Plan) is based upon the following mission statement for all City utilities, including the City water system:
“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 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.

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

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.

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

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.

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.

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

5.3.3.11 Water Main Extension by Developers
All water main extensions including fire hydrants, valves, water services stubs, meters, and
related appurtenances, with the exception of private fire sprinkler lines and systems, shall be
conveyed, at no cost, to the City for ownership, maintenance and operations, after the City’s
acceptance of the water main extensions. 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.

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.

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.

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.

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.

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.

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

established for all facilities, equipment, and processes. Spare parts shall be stocked for all equipment items whose failure will impact the ability to meet other policy standards.
All maintenance personnel shall be trained in the procedures and techniques necessary to efficiently perform their job descriptions. 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.

staff reviews and approves projects for the maintenance and repair of water treatment facilities,
booster pump stations, and reservoirs (except for the recoating of the interior of reservoirs). 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.

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.

6.5 Water Supply Interties
In the coming years, as the limits of water rights are encountered, the City plans to purchase more water from SPU to meet its needs. 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.

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.

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.

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 supply and pumping analyses only account for non-emergency supply sources. 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.

6.13.3 System Recommendations
This 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.
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.

7.3 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. 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.

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.

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.

7.3.1.3 Standby Storage and Fire-Suppression Storage
Standby Storage volumes are required to supply reasonable system demands during a system emergency, such as the disruption of the water supply caused by a transmission pipeline or
equipment failure, power outage, valve failure, or other system interruptions (as discussed in Chapter 5). Table 7.5 shows the required standby storage for each operational area.
The Washington State Department of Health (DOH) Water System Design Manual recommends a
minimum standby storage of no less than 200 gallons per Equivalent Residential Unit (gal/ERU).

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.

7.3.1.4 Dead Storage
Dead storage volume is the volume at the bottom of the storage tank that cannot be used
because it’s physically too low to be withdrawn from the tank or, if withdrawn from the tank, would result in water pressures in the distribution system that are below the acceptable criteria
of 20 psi during a fire or emergency situation. 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.

Note, there are two customers in the North Talbot/Mt Olivet area with higher service elevations
than the one noted in Table 7.8. One property is a vacant lot (4521 Talbot Rd S) with a service
elevation of 159 ft (the nearest model junction is J4367), while the other property is a single-family home located at 5218 Talbot Rd S with a service elevation of 140 ft (the nearest
model junction is J6057). The City is in the process of moving these customers to the
Talbot Hill 350 PZ; therefore, they are not included in the group of customers with the highest
elevations in that service area.

7.3.2 Storage Analysis by Operational Area
The seven operational areas were evaluated as separate systems to ensure that each has the
required usable operational, equalizing, fire, and standby storage volume, as summarized below.
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.

7.3.2.2 West Hill 495 Operational Area
Storage for the West Hill 495 Operational Area is contained within the West Hill Reservoir, which has a total storage volume of 1.39 MG. 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).

7.3.2.3 Highlands 445 Operational Area
Storage for the Highlands 445 Operational Area is contained within the two new reservoirs the City is currently building: Highlands 445 Reservoir and Kennydale 308 Reservoir. 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.

7.3.2.4 Highlands 565 Operational Area
Storage for the Highlands 565 Operational Area is contained within the Hazen and Highlands 565
Reservoirs, which together have a total storage volume of 4.95 MG. 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.

Storage for the Rolling Hills 590 Operational Area is contained within the Rolling Hills 590 Reservoir, which has an available storage volume of 0.3 MG. 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.

7.3.3 Storage Recommendations
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 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.

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.

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. During any fire event, the minimum pressure should be greater than 20 psi at the end of the fire
in the entire distribution system. Figure 7.5 additionally shows the fire flow required at nodes throughout the system according to land use. Only junctions near hydrants were assigned a fire flow.

7.4.2 Pressure Results
The model was run in extended period simulation (EPS) for 1 week at average day demand (ADD) and MDD to evaluate general pressure-system conditions for the near-term and long-term planning years. 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.

7.4.3 Velocity Results
The City's goal is to maintain velocities under 8 feet per second (fps) in distribution pipes during
PHD. 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.

7.4.5 Distribution System Recommendations
This section offers recommendations to meet the deficiencies identified in the previous section.
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.

7.4.5.4 Dead-end Pipes in Non-Single Family Areas
The City has multiple older 4-inch, 6-inch, or 8-inch diameter 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.
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.

7.5 Limiting Capacity Analysis
The limiting capacity of the City’s physical water system was determined for the 2039 planning
year with the assumption that all recommended improvement projects will be online. 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.

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

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.

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.

7.6.3 Remaining Useful Life Evaluation
As part of the pipeline replacement program, the City’s existing pipes were assessed for their conditions through a RUL analysis.
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.

CHAPTER 08 | WATER SYSTEM PLAN UPDATE | CITY OF RENTON
FINAL | MAY 2021 | 8-1
Chapter 8 OPERATIONS AND MAINTENANCE
8.1 Water System Management
This section describes the tasks and responsibilities of the operations and maintenance (O&M) staff that serve the City of Renton’s (City) water system. Each member functions under the City’s Maintenance Services Division.
Chapter 1 – Introduction (specifically, Figure 1.2, City of Renton Drinking Water Organization) explains how the water system is organized.
8.1.1 Normal Day-to-Day Operations
Normal, day-to-day operations of the Water Utility fall under the responsibility of the Water Maintenance Services Section directed by Water Maintenance Manager, George Stahl.
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.

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:

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.

9.3 Cost Estimating Assumptions
9.3.1 Cost Estimate Level
The CIP cost estimates in this chapter are Class 5 estimates (budget-level estimates). 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.

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

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.

(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

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

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

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

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

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. As mentioned before, each project is assigned a CIP Identification. Table 9.15 details
all projects identified and defined in this chapter and identifies the planning period (short-term,
long-term, or annual) determined for each project and project type.
Figure 9.3 illustrates the locations of the specific projects identified, while Figure 9.4 illustrates
these projects phased between short and long terms. Distribution system improvements
highlighted on Figure 9.3 includes both fire flow and velocity recommendations.
Figure 9.5 and Figure 9.6 illustrate the location of projects included in the programmatic CIP,
which are not included in any of the specific projects. Figure 9.5 presents City’s recommended
program P-01, while Figure 9.6 presents City’s recommended program P-03.
An individual project sheet was generated for each CIP project and includes project identifier,
description, costs, project type, timeline, and comments to help with future implementation. To
help the City identify individual projects, project sheets are separated by project category. Appendix T includes all the project sheets.

FINANCIAL PROGRAM
10.1 Introduction
This chapter summarizes the City of Renton’s (City) financial status and provides a cursory
evaluation of its ability to finance the necessary capital improvements identified in the capital
improvement plan (CIP). 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. Additional

10.2.2 Financial Operations
Based on the information provided, the Water Utility’s revenues and expenditures in the period
from CY 2016 to CY 2019 are summarized in Tables 10.3 and 10.4. 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.

Figure 10.1 shows a graphical representation of the Water Utility’s historical financial
performance. 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.

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.

10.5 Findings and Results
This section summarizes the results of the financial sufficiency evaluation according to the
three funding strategy scenarios introduced in Section 10.3.3.
10.5.1 Projection Results without Rate Increases
Figure 10.2 summarizes the Water Utility’s overall financial forecast, assuming that no further
rate increases (beyond the CY 2020) are implemented. 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.

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.

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.

Given the rate increases discussed for Scenario 1, Figure 10.6 estimates the monthly bills
for 3/4-inch meter single family residential customers with monthly use of 7 CCF for each year of
the analysis: bills would increase from $48.65 in CY 2020 to $64.61 by CY 2029. 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.

Total $23.50 $0.256
Notes:
(1) Totals may not sum due to rounding.
(2) Issuance amount includes 1 percent issuance costs and a debt-service reserve requirement equal to 1 year of debt-service
payments.

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.

10-Year Sum (Millions)
Cash Funded Capital (PAYGO and Reserves) $53.4
Additional Debt $23.5
Total CIP Funding $76.9
Note:
(1) Totals may not sum due to rounding.
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.

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. Table 10.10 summarizes the revenue requirement, cash flow, and
fund balances for the next 10 years if Scenario 2 is implemented

Given the rate increases discussed for Scenario 3, Figure 10.14 estimates the monthly bills
of 3/4-inch meter single family residential customers with monthly use of 7-CCF for each year of
the analysis: bills will increase from $48.65 in CY 2020 to $67.27 by CY 2029, the lowest overall
increase seen among the scenarios tested.
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

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.

For Use by Local Governments and Municipal Water Suppliers
This checklist may be used to meet the requirements of WAC 246-290-108. 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. Please include: name of contact, date, and efforts made (letters, phone calls,
and emails). To self-certify, please contact the DOH Planner.

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.

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.

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.

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

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.

I’m the new UTRC chair (aka the new Steve Hirschey), so please send it to me. We’re only accepting

Submitting your plan within the next week or two should get you on September’s UTRC agenda. All

I’m reaching out because the City of Renton is prepared to submit our draft 2019 Water System Plan
Update to the King County UTRC for review. To date, our correspondence has been with Steve
Hirschey, but I received a message that my recent email attempts to Steve have failed. The emails
keep bouncing back. Because of the 2019 coronavirus situation, City of Renton staff are working
remotely and we are only able to provide an electronic pdf version of the draft plan at this time.
Could you please confirm whom I should send the electronic submittal to?

Hi Kelly,
Just wanted to touch base again about SPU comments for Renton’s 2019 Water System Plan Update.
We are in the process of finalizing our comments log because we recently received comments back
from DOH. The comments from DOH and others appear to be pretty minor so we anticipate a quick
turnaround. There is still some time to prepare your comments, but I think we will be trying to
present the plan to our city council directly after the holidays.

I’m afraid I let this slip thru the cracks with all the chaos this summer.
I am heading out tomorrow on vacation and will return on Tuesday Oct 6. I will make this a priority

Hi Kelly,
I’m checking back to see if SPU has had a chance to review our draft 2019 Water System Plan
Update. This summer has been crazy especially given that we recently experienced some major
computer/email issues here at Renton so just wanted to follow-up to make sure I hadn’t missed
anything from you guys during our cyber incident.
We have received comments back from several other adjacent systems and anticipate hearing back
from DOH soon so we’ll be moving forward on finalizing the plan.
Hope you're doing well. Thanks!

RE: Water System Plan Comment Letter
City of Renton – 2019 Water System Plan (DOH Submittal #20-0803)
Dear Mr. Gafour:
Thank you for the opportunity to review the City of Renton 2019 Water System Plan (WSP), dated March 2020
and received by Ecology on August 10, 2020. 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. This system
removes issues with duplication of certificate numbers for surface and groundwater rights issued prior to 1971
and with 1945 groundwater claims/declarations. The table below provides a list of Renton’s thirteen (13)
certificates and four (4) permits, including the tracking numbers, as found in Ecology’s databases.

Hi Katie,
There were no additional comments from the UTRC added to the 9/16 draft letter, so it can be
considered the final comments of the UTRC.
We request that, when you resubmit, you include a letter that addresses these points (even though
some were explained on the record at UTRC) and as applicable where the information can be found
in the revised plan. We also ask that, if you’ve made significant or important changes based on
review from other organizations, that you identify those and direct us to them in the new version as
well.

Included are a combination of comments, questions, and requests based on my review and analysis.
Please note that you don’t need to have materials prepared or submitted before the meeting. You’ll

On June 30, 2020, the King County Utilities Technical Review Committee (UTRC) received a water system
plan for review from the City of Renton. 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

• 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.

Local Government with Jurisdiction Conducting Review:At
Before the Department of Health (DOH) approves a planning or engineering submittal under Section 100
or Section LLO, the local government must review the documentation the municipal water supplier
provides to prove the submittal is consistent with local comprehensive plans, land use plans and
development regulations (WAC 246-290-108). Submittals under Section L05 require a local consistency
determination if the municipal water supplier requests a water right place-of-use expansion. The review
must address the elements identified below as they relate to water service.
By signing this form, the local government reviewer confirms the document under review is consistent
with applicable local plans and regulations. If the local government reviewer identifies an inconsistency,
he or she should include the citation from the applicable comprehensive plan or development regulation

Consistency Review Guidance
For Use by Local Governments ond Municipal Water Suppliers
This checklist may be used to meet the requirements of WAC 246-290-108. When using an alternative
format, it must describe all of the elements; 1-a), 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(4XbXii)).
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 fo cifies 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 8.07,
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. Please include: name of contact, date, and efforts made (letters, phone calls,
and emails). To self-certify, please contact the DOH Planner.
The Department of Health is an equal opportunity agency. For persons with disabilities, this document is available on request in other

Hi Cynthia,
My apologies for not getting back to you yesterday. Through the end of July, I am out Mondays on
furlough to help respond to the economic challenges the City is facing from COVID-19. Our
maintenance crews are working normal schedules, but taking similar safety precautions such as self-
screenings and face coverings.
I really appreciate your response and question - a spreadsheet format would work great for us
because we will compile all comments into a spreadsheet for the final plan, similar to the 2012 WSP
comment log shown below. Noting the page or section for each comment would be very helpful for
our reference.
Feel free to reach out with any other questions!
Thank you so much! I hope all is well.

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

Again, thank you for keeping us informed. It is very much appreciated.

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. The ERU values were not used to develop the projections for the large Note will be added to the table.Renton Initial Comments 2020-0916.pdfNatalie Completed

CAG-02-123
AGREEMENT FOR THE SALE OF WATER
IN AN EMERGENCY BY
THE CITY OF RENTON TO THE CITY OF SEATTLE
This AGREEMENT made and entered into this 30th. day of November , 2002, by
the CITY OF RENTON, a municipal corporation of the State of Washington, hereinafter
called "RENTON" and the CITY OF SEATTLE, a municipal corporation of the State of
Washington, acting through Seattle Public Utilities, hereinafter called "SEATTLE".
WHEREAS, SEATTLE and RENTON have existing interties between their water
systems;
WHEREAS, SEATTLE sometimes experiences a Spring water supply shortage due
to low snowpack, precipitation and inflows in the Cedar and Tolt River watersheds, or, a hot
Summer with high water consumption coupled with a delay in usual Fall rains;
WHEREAS, SEATTLE may also experience other types of emergency situations
that call for an augmentation of its water supply, such as a transmission pipeline break or an
episode of high turbidity in one of its reservoirs;
WHEREAS, RENTON, in the spirit of intergovernmental cooperation during such
water supply emergencies, is willing to sell an increment of water to SEATTLE when
available during non-peak periods;
WHEREAS, SEATTLE is willing to sell water to RENTON to allow RENTON's
ground water aquifer to recharge, when water is available following a water shortage
emergency; and,
WHEREAS, the parties desire to enter into an AGREEMENT providing for the sale
of water in an emergency from RENTON to SEATTLE, and for the subsequent sale of an
equivalent amount of water from SEATTLE to RENTON, if necessary, to allow recharge of
RENTON's Aquifer.
NOW THEREFORE, IT IS AGREED AS FOLLOWS:
1) Term of AGREEMENT. The effective date of this AGREEMENT shall be
November 30 2002. The AGREEMENT shall be in effect until
December 31, 2011, unless terminated by either party in accordance with Section
17 of this AGREEMENT. The rates and quantities of water sold are set forth in
Sections (2), (8), and (11).

2) Sale Price of Renton Water. SEATTLE shall pay to RENTON for all water delivered
1.30 per 100 cubic feet, which is a special wholesale rate for 2002; and revised
each year during the term of the agreement. The rates charged by RENTON are
based on RENTON's analysis of cost of providing non-peaking service to Seattle
under the conditions stated herein. This rate was calculated using the American
Water Works Association (AWWA) "Base Extra Capacity" method of rate analysis.
The rate charged to SEATTLE shall be adjusted each year using the AWWA "Base
Extra Capacity" method and RENTON's retail water rate for each year.

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. Prior to
any delivery of water, information on current water quality will be provided to the
receiving party so that blending, compatibility and other water quality issues can be
evaluated and addressed.
8) Quantity of Water. Depending upon water availability in the RENTON system,
RENTON shall make available for purchase by SEATTLE up to the approximate
amount of two million (2,000,000) gallons per day from the existing emergency
intertie located at the Tiffany Park Pump Station. The rate of delivery of water from
Tiffany Park Pump Station system to SEATTLE's system shall vary between zero
and approximately 1,400 gallons per minute. Also in the fall and winter RENTON
may make available an additional amount up to approximately three and one-half
million (3,500,000) gallons per day from the intertie at Union Avenue SE and SE 2nd

9) Miscellaneous Control Devices. RENTON reserves the right to require SEATTLE to
install, as a condition of water service, pressure reducing valves, backflow
preventative devices, pressure relief valves, back-pressure sustaining valves,
pipeline flow limiting devices or similar devices at locations where RENTON
determines a need to protect its facilities.
10) Coordination and Project Management.
A) Operations:
For the purpose of operating the interties between RENTON and SEATTLE,
coordination shall occur between representatives of the systems, who are:
Ms. Lys Hornsby, City of Renton

11) RENTON's Aquifer Recharge. 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.

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.
IN WITNESS WHEREOF, the parties have hereunto set their hands this day and year

a comprehensive fashion up to and including extending said facilities to the far
side of the property, when appropriate, to provide a connection point for the
future (or existing) facilities of the next property.
14. Franchise Agreement. Upon RENTON annexing property within the SWSD
service area, RENTON shall grant SWSD, 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 SWSD and have a term not to exceed 3
(three) years.
RENTON and SWSD will immediately begin negotiations for a new franchise for
the purposes of rights-of-way use for SWSD service area within RENTON. The
new franchise shall be negotiated within three years.
Upon any subsequent annexations by RENTON within the SWSD 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 SWSD.

reasonable expert witness fees and reasonable attorney's fees and the reasonable costs of the
City, including reasonable attorney's fees for recovery under this indemnification clause.

rights -of -way and the establishment and improvement thereof, freeway construction, change or
establishment of street grade, or the construction of any public improvement or structure by any
governmental agency acting in a governmental capacity, provided that the District shall in all
such cases have the privilege to temporarily bypass, in the authorized portion of the same street
upon approval by the City, any water or sanitary sewer line or portion thereof required to be
5
temporarily disconnected or removed; and provided further, that this provision will not apply to
District installations located within easements owned by the District.
The City shall consult all as -built maps and plans filed by the District pursuant to
this Agreement or any permits authorized under this agreement, in order to determine whether
the District has placed pipe or facilities in any area affected by a proposed City project. The City
will make its best effort and attempt to design or redesign streets, avenues, alleys or public places
or ways, and other City utilities to minimize the impact thereof on the District's existing sanitary
sewer systems, including the need to require the District's facilities to be relocated and shall
coordinate with the District in accordance with RCW 35.21.905. PROVIDED HOWEVER, that
the City shall make the final determination on the need for relocation of the District's facilities.
Whenever the City determines that any of the above circumstances necessitate
the relocation of the District's then existing facilities, the City shall notify the District in writing,
And provide the District with copies of pertinent portions of the plans and specifications for such
project so that the District is able to relocate its facilities to accommodate the City's project.

time that is reasonable given the circumstances surrounding the project. The City understands
that pursuant to RCW 57.08.050, the District is required to comply with certain notice and bid
procedures prior to commencement of any construction project. Whenever practical, given the
circumstances surrounding the City's project, the City shall provide the District with sufficient
notice to enable the District to comply fully with RCW 57.08.050 without resorting to
emergency powers granted therein. Upon the District's failure to complete relocation of its

expense. The District shall complete the relocation work at least ten (10), days prior to the
project's commencement unless the parties agree on a different schedule.
If, after reviewing the as -built maps and plans submitted by the District, the City
determines that the District's pipe or facilities will not be affected by a proposed City project, no
notice shall be given to the District. The City may then commence construction and if the City
finds that the District's as -built maps and plans are inaccurate through the actual discovery of
pipe and facilities in the construction area, the City shall notify the District and allow the District
twenty -four (24) hours, when reasonable, to remove and/or relocate its pipe and facilities.
However, should the District be unable to remove and/or relocate its pipe and facilities within

the City, which application shall detail, to the City's satisfaction, the location of all pipe or
facilities to be abandoned by providing to the City with the abandonment application current as-
built drawings showing the exact location of all pipes or facilities to be abandoned, and the
procedures the District plans to implement in order to comply with all local, state, and federal
regulations pertaining to abandonment of water and sanitary sewer pipe and facilities constructed
of asbestos cement or other materials containing asbestos, The District shall, at its sole cost and
expense, and pursuant to all local, state, and federal regulations, remove and properly dispose of
all abandoned pipes and facilities when so directed by the City for any reason, with cause.
PROVIDED, that in no event shall the City direct or require the District to remove abandoned
pipes or facilities on the basis of standards not equally applied by the City to require the removal
of pipes or facilities abandoned by the City in similar circumstances. The District will commence
the removal and disposal of the abandoned facilities within thirty (30) calendar days, and will
fully complete the removal within one hundred eighty (18 0) calendar days from the date the City
directs the removal, unless the City agrees, in writing, to extend the time for removal. In addition
to and in clarification of the indemnity provisions in Section 8, the District specifically shall
defend, indemnify and hold the City, its officers, officials, employees, agents and volunteers
harmless from any and all claims, injuries, damages, losses or suits, including all legal costs and
attorney fees arising out of or in connection with the abandonment and /or removal of pipe and
facilities constructed of asbestos cement or other material containing asbestos. In the case of
street vacations, the City shall, to the extent possible, retain and grant an easement to the District
for any pipe and facilities then in use by the District. The City shall give notice to the District of
any proposed project or street vacation requiring removal of abandoned pipe and facilities as set

maintenance, or repair of the District's facilities and installations located within the City's rights
of way and property, all surface structures, if any, shall be erected and used in such places and
positions within said public rights -of -way and other public properties so as to interfere as little as
possible with the free passage of traffic and the free use of adjoining property, and the District
shall at all times post and maintain proper barricades during such period of construction as
required by state law or city ordinance.

purpose of installation, repair, maintenance, or relocation of its facilities, it shall apply to the
City for a permit to do so and except in the case of an emergency, shall give the City at least
three (3) working days notice thereof. In the event that emergency work is required, the District
may, without prior written notice to the City, request permits by telephone. The Director shall
grant or deny such permits by telephone, but the District shall follow -up all phone emergency
permit requests with a written application within three (3) working days of the telephone
notification to the Director In all other cases, the City shall approve the District's applications for
permits as soon as reasonably possible. During the progress of the work, the District shall not
unnecessarily obstruct the passage or proper use of the right -or -way, and shall file maps or plans

area covered by this Agreement and as described in this section, the party planning such
excavation shall afford the other, upon receipt of a written request to do so, an opportunity to
share such excavation, PROVIDED THAT: (1) such joint use shall not unreasonably delay the
7
work of the party causing the excavation to be made; (2) such joint use shall be arranged and
accomplished on terms and conditions satisfactory to both parties; and (3) either party may deny
such request for safety reasons.
Prior to commencement of any construction authorized by this agreement, the
District shall reference all monuments and markers of every nature relating to subdivision plats,
highways and all other surveys for review and inspection by the City. The reference points shall
be so located that they will not be disturbed during the District's operations under this
Agreement. The method of referencing these monuments or other points to be referenced shall be
approved by the Director before placement. The replacement of all such monuments or markers

by the Director. The costs of monuments or other markers lost, destroyed, or disturbed and the
expense of replacement by approved monuments shall be borne by the District.

10. Sewer Service Area Boundary Between RENTON and THE DISTRICT. With the
above transfer (sale) of existing facilities and service area, and reasonable
service area limits corresponding to this action, the line separating the RENTON
service area from THE DISTRICT service area for sanitary sewers is described
in attached Exhibit "F", and is shown in attached Figure 11 . 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:

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.

operating and maintaining jointly used storage and transmission facilities, and to ensure that the
District will receive the water supply and jointly used facilities capacity stated in this contract

also is to supersede and replace the prior agreement between the City and King County Water
District No. 63, the predecessor to the District, dated March 4, 1983, as amended by Agreement
Amendment No. 1 dated December 30, 1985.

the right to amend Exhibit D annually by letter signed by the authorized
representatives of the parties.
"District" shall mean Bryn Mawr-Lakeridge Water and Sewer District,
King County, Washington and its successors in interest.

hereof.
"Joint Facilities Costs", for Joint Facilities, shall be as described in
Exhibit C, attached hereto and made a part hereof. For future joint
facilities, Joint Facilities Costs shall include all costs and expenses

f. "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.

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

shall be included in the City's Maintenance and Operation Expenses. 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 -

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.

MEMORANDUM JAN - 1999
CITY OF ,=tt-NTON
Engineer rig Dept,
To: Mike Benoit
From:Lawrence J. 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.

Appendix G WATER LOSS CONTROL ACTION PLAN (WLCAP)
City of Renton
Water System Plan Update
APPENDIX G
WATER LOSS CONTROL ACTION PLAN
I.INTRODUCTION
The City of Renton (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 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.

VI.PLANNED ACTIVITIES FOR FURTHER REDUCING DISTRIBUTION SYSTEM LOSS
The City will continue to implement its Ongoing Activities, stated above, as part of the WLCAP. 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.

VIII.POTENTIAL ISSUES IN IMPLEMENTATION OF WATER LOSS CONTROL
Issues may arise that could delay implementation of the activities identified in this WLCAP.
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.

Water Reclamation Evaluation Checklist
For Systems with 1,000 or more Connections
The County and State recognize that changing conditions could initiate a need to
respond in new ways to future water quality standards, wastewater discharge
requirements, take advantage of advances in treatment technologies and/or allow
our region to be positioned to respond to changes associated with climate change
and population growth.
In 2003, Chapter 90.46 of the Revised Code of Washington (RCW) was amended
to require public water systems serving 1,000 or more connections to evaluate
opportunities for reclaimed water when completing their water system plans.
Please use this checklist to meet King County consistency requirements in
responding to this legislation.

RENTON WHPP UPDATE
FEBRUARY 2019
1.0 INTRODUCTION
This report summarizes contaminant risks to groundwater supplies for the City of Renton
(City). 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.

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-

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

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.

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:

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

HWG
Facilities that generate any quantity of a dangerous waste. They may
be classified as small, medium or large quantity generators (SQG,

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.

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.

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.

Notes:
DT = Downtown; MPW = Maplewood; SBS = Springbrook Springs; 5A = Well PW‐5A
HWG = facility generates hazardous waste.
HWP = facility generates over 2640 lbs hazardous waste per year.
HWOTHER = Facility does not generate or manage hazardous waste, but includes transporters of hazardous waste, used oil
recyclers, and dangerous waste fuel marketers & burners.
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). Facility names with no parentheses in their entry use the FSID facility name.

Home heating oil counts presented in this table are approximate because large parcels overlapping two time‐of‐
travel zones are counted in both.
The 5 year DT WHPA overlaps the 1 and 5 year MPW WHPAs. Because the time of travel to the MPW wellfield is
less than or equal to the time of travel to the DT wellfield, home heating oil tanks in this overlapping region
were counted only as part of the MPW WHPAs.

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 .

Re: City of Renton Aquifer Protection Program
To Whom It May Concern:
The City of Renton has developed an updated Aquifer Protection Program Plan to help
maintain drinking water quality for our city residents. 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.
Sincerely,
Katie Nolan

Re: City of Renton Wellhead Protection Plan
Dear Department of Ecology:
The City of Renton has developed a Wellhead Protection Plan (which is referred to as the
Aquifer Protection Program Plan in City materials) to help maintain the drinking water
quality for our city residents. 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. If you have any questions or would like a
copy of the wellhead protection plan, please contact me at (425) 430-7335.
Sincerely,
Katie Nolan

where potential contaminant releases could adversely impact the quality of our
community’s drinking water supply.
A map of the APAs and adjacent transportation routes is enclosed for your review. An
acknowledgement of receipt of this information or a response from your office as part of
our aquifer protection plan documentation would be appreciated.
We ask that you review the enclosed copy of the City’s current spill response plan so
appropriate procedures are followed and necessary coordination occurs in the event of a
spill or contaminant release.

hydrostatic test shall be re-run at the Contractor’s expense until a satisfactory test is
obtained.
5-20.5 HYDROSTATIC TESTING FIRE SERVICES
A. When hydrants are included with the section of main pipe to be tested, the testing shall be
conducted in three separate tests as follows.
1. Test No. 1 – Water main gate valves and hydrant auxiliary gate valves closed, with
the hydrant operating stem valves and hose ports wide open.
2. Test No. 2 – Water main gate valves and the hydrant operating the stem valves
tightly closed but the hydrant auxiliary gate valves and hose ports wide open.
3. Test No. 3 – Each hydrant shall be tested to the pressure indicated in Section 7-
09.3(23) of the WSDOT Standard Specifications with the hydrant auxiliary gate valve
and hose ports closed and the hydrant operating stem valve wide open.

Association (NFPA) Standards 13 and 25, with no loss for two hours.
5-20.6 TESTING EXTENSIONS FROM EXISTING MAINS
A. When an existing water main is extended with new pipe to a new valve and the distance
from the existing pipe to the new valve is 18 feet (18') or less, the section of new pipe
installed between the new valve and the end of the existing main shall be made with pre-
tested, pre-chlorinated pipe, and no hydrostatic test will be required. When the required
hydrostatic tests are conducted in the new main section beyond the installed new valve in
the closed position, the normal pressure of the existing main may be present against the
other side of the new valve.
B. Where the distance between the end of an existing water main pipe extension to the new
valve is more than 18 feet (18'), the connection of the new pipe to existing pipe shall not be
made until after hydrostatic tests have been made to the required pressure in both
directions against the new valve. This shall be accomplished by a temporary cap or plug
installed on the end of the new pipe, beyond the new valve, as close as possible to the
existing pipe for testing purposes.
C. The short length of pipe between the temporary cap or plug end with the new valve in the
closed position, with no hydrostatic pressure active on the opposite side of the valve, shall
be subjected to the required test pressure. The same test shall be made against the other
side short section of pipe toward the existing main. The final connection to the existing main
shall be made with pre-tested pre-chlorinated pipe.

APPENDICES | WATER SYSTEM PLAN UPDATE | CITY OF RENTON
FINAL | MAY 2021
Appendix L CROSS CONNECTION CONTROL PLAN
City of Renton
Water System Plan Update
APPENDIX L
CROSS CONNECTION CONTROL PLAN
I. 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.

I. 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).

Recording and Reporting: Water quality maintenance staff record raw data 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.
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.

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.

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.

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,

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.

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

not been established. The regulated and unregulated SOC analytes are covered by DOH TEST PANELS:
PEST1, HERB1, INSECT1, and FUMIGANT. Direct the laboratory to analyze for SOCs for drinking water
compliance monitoring. DOH may require any or all of the test panels; however, the City currently has
state waivers for insecticides, pesticides, and soil fumigants.

V. 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.

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.

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.

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.

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.

The water distribution system serves the valley floor and five surrounding hills: West Hill, Highlands, Renton
Hill, Talbot Hill, and Rolling Hills. There are 16 hydraulically distinct pressure zones, and moving water
between pressure zones is accomplished by 12 booster pump stations (BPS) and 45 pressure-reducing valve
(PRV) stations located throughout the City. There are approximately 308 miles of water main in service.

II. 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.

Triggered Source Water Samples: Triggered source water samples are used to help determine whether the
coliform presence in the distribution system is due to fecal contamination in a groundwater source.
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.
Triggered Source Water Sampling Site Locations: Source sampling sites are also shown on the site maps.

Invalid Samples: The DOH or laboratory may determine that a sample is invalid, based on the conditions
specified in WAC 246-290-300(3)(d). Follow-up sampling is required within 24 hours of invalidation of the
sample. Contact the DOH for guidance.
III. WHOLESALE CUSTOMER NOTIFICATION
Consecutive systems must contact the wholesaler within 24 hours whenever they receive an unsatisfactory
routine coliform sample result.
The City currently provides wholesale water to Skyway Water & Sewer District through a single connection
located in the West Hill 495 pressure zone. If Skyway notifies the City of an unsatisfactory routine distribution
sample, triggered source water samples must be collected immediately from the sources in use. If triggered
source monitoring indicates that E.coli are present, the City must contact Skyway within 24 hours of being
notified of the positive result.

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. TEMPLATES FOR PUBLIC NOTIFICATIONS
The following pages contain instructions and templates for issuing Tier 1, Tier 2, and Tier 3 public
notifications.
RTCR Public Notification Templates 3

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

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.

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. If you modify this notice, you must still include
all required public notice elements from 40 CFR 141.205(a) and leave the mandatory language unchanged (see below). All
posted notices must remain in place for as long as the violation or situation persists but in no case for less than seven days,
even if the violation or situation is resolved.
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.
*Coliforms are bacteria that are naturally present in the environment and are used as an indicator that
other, potentially harmful, waterborne pathogens may be present or that a potential pathway exists
through which contamination may enter the drinking water distribution system. We found coliforms
indicating the need to look for potential problems in water treatment or distribution. When this occurs, we
are required to conduct assessments to identify problems and to correct any problems that are found.*
You are also required to include one or both of the following statements, also presented in this notice in italics with an
asterisk on each end, as appropriate for the violation:
*We failed to conduct the required assessment.*
*We failed to correct all identified sanitary defects that were found during the assessment that we
conducted.*
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 provided below and presented in this notice in italics with an asterisk on
each end.
*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.*
Corrective Action
The specific cause(s) of total coliforms in the distribution system that triggered the assessment will likely differ from system
to system. Your notice must describe the corrective action(s) you are taking [40 CFR 141.205(a)(7)] to address the TT violation
and when you expect to return to compliance or resolve the situation [40 CFR 141.205(a)(8)]. You can use one or more of the
following statements, if appropriate, or develop your own text.
• We have begun to correct the sanitary defect(s) identified during an assessment of our water system by taking the
following corrective actions: [Describe corrective actions].
• To ensure that our water system is protected against contamination, we are working with the state to implement the
following corrective actions: [Describe corrective actions].
• We completed the required assessment and identified the cause of the sanitary defect to be addressed [describe the
issue or problem found, for example, damage to the storage tank, a missing vent screen, etc.] We are currently
correcting the problem on a schedule approved by [State Department of Public Health].
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 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) and Template NC-7 of the Public

IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER
[Water System Name] Failed to Perform Activities Required to Address Coliform
Bacteria Contamination of the Water System
During recent routine monitoring, our water system tested positive for total coliforms. *Coliforms are bacteria that are
naturally present in the environment and are used as an indicator that other, potentially harmful, waterborne pathogens may
be present or that a potential pathway exists through which contamination may enter the drinking water distribution system.
We found coliforms indicating the need to look for potential problems in water treatment or distribution.
When this occurs, we are required to conduct assessments to identify problems and to correct any problems that are found.*
[Describe the TT violation, using the mandatory language of *We failed to conduct the required assessment* by [Enter date
the assessment was due] and/or *We failed to correct all identified sanitary defects that were found during the
assessment(s)* by [Enter date correction was due].]
As our customers, you have a right to know what happened and what we are doing to correct this situation.
What should I do?
• You do not need to boil your water or take other corrective actions. However, if you have specific health concerns,
consult your doctor.
• If you have a severely compromised immune system, are pregnant, or are elderly, you may be at increased risk and
should seek advice from your healthcare provider about drinking this water. You should also seek advice from your
healthcare provider about using the water if you have an infant. General guidelines on ways to lessen the risk of
infection by bacteria and other disease-causing organisms are available from EPA’s Safe Drinking Water Hotline at 1-
800-426-4791.
What does this mean?
Since total coliform bacteria are generally not harmful themselves, this is not an emergency. If it had been you would have
been notified within 24 hours.
Failure to identify and correct the defects has the potential to cause continued distribution system contamination.
Inadequately treated or inadequately protected water may contain disease-causing organisms. These organisms can cause
symptoms such as diarrhea, nausea, cramps, and associated headaches.

IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER
Monitoring Requirements Not Met for [System]
Our water system violated drinking water requirements over the past year. Even though these were not
emergencies, as our customers, you have a right to know what happened and what we are doing (did)
to correct these situations.
*We are required to monitor your drinking water for specific contaminants on a regular basis. Results
of regular monitoring are an indicator of whether or not our drinking water meets health standards.
During [compliance period] we [‘did not monitor or test’ or ‘did not complete all monitoring or testing’] for
[contaminant(s)] and therefore cannot be sure of the quality of your drinking water during that time.*
What should I do?
There is nothing you need to do at this time.
The table below lists the contaminant(s) we did not properly test for during the last year, how often
we are supposed to sample for [this contaminant/these contaminants], how many samples we are

Self-Assessment Guideline for Coliform Detection
The Revised Total Coliform Rule became effective on April 1, 2016. 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.

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.

II. 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.

IV. 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

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.

I.INTRODUCTION
A. 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.

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.

A. 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.

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.

• 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.

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”.

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

MODEL CALIBRATION PLAN
2.1 Overview
This calibration plan covers each of the calibration processes, specifically focusing on data
gathering needs for an accurate and complete calibration of the City of Renton’s (City’s) water
system hydraulic model.
2.1.1 Schedule
Field testing and data gathering for the model calibration will tentatively take place from
June 18th through July 20th. 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.

DRAFT | JUNE 2018 | 2-5
2.2.3 Water System Controls Review
It is important to understand the overall operational objectives regarding prioritization of various
water supply sources and key system facilities, prior to input of model controls. 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

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).

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.

2.3.5.2 Format of Data
SCADA Data
All SCADA data needs to be provided in Microsoft (MS) Excel or a MS compatible database
format. 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.

Note:
(1) This sample was taken from a different SCADA system and thus may not represent the exact format of the City’s SCADA
output.
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.

Appendix Q HYDRAULIC MODEL DEVELOPMENT AND CALIBRATION
APPENDIX Q – HYDRAULIC MODEL DEVELOPMENT AND CALIBRATION| CITY OF RENTON
DRAFT | FEBRUARY 2020
Section 1
INTRODUCTION
This appendix provides an overview of the procedures used in the development and calibration
of the City of Renton’s (City’s) water system hydraulic model, as part the City’s Water System
Plan Update.
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.

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

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.

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

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.

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.

VLY196 Re‐zone
Intersection of SE Carr Rd and Talbot Rd S.
Re‐zone area to address low pressure and fire flow deficiencies and in VLY196 on transmission main north of Springbrook Springs. Hydrant S‐
00235 at 401 S 43rd St & Talbot Rd will need to be re‐zoned, decommissioned, or removed.
From Ch 7: " Storage analysis showed that the Valley area is deficient for all planning years till 2039 to supply operational and equalizing
volumes at 30 psi to the highest customers. The area has sufficient storage at 20 psi. To address this issue, the City is in the process of
connecting high elevation residents within the Valley 196 zone to higher pressure zone infrastructure. These improvements will provide
adequate operating pressures and fire flow pressures to these high elevation residents as well."

Monroe Ave BPS Generator
Monroe Ave BPS
With the existing reliable sources and reservoirs, the Highlands 565 Operational Area does not have sufficient storage for all planning years till
2039. The Highlands 565 area is deficient by 1.26 MG by 2029 and 1.65 MG by 2039.
Excess storage located in the Highlands 445 Operational Area is sufficient to offset deficiency in Highlands 565. 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). The City is already planning on adding a generator at
Monroe BPS as part of the construction of the new 6.3 MG reservoir in Highlands 445 pressure zone.

As shown in the storage analysis, with the existing reliable sources and reservoirs, the Rolling Hills 590 Operational Area does not have sufficient
storage for all planning years till 2039. Analysis shows that the operational area is deficient by 0.95 MG by 2039. 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.

West Hill 495 Storage
West Hill 495 PZ
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. It is recommended that the City update operational strategy and reduce the operational band thus decreasing the
operational volume and mitigating deficiencies.
