This plan is an update of the plan adopted in 1984, and complies with WAC 248-54-580. The plan is based on current policy, regulations and law adopted by Federal and State government and the Renton City Council. This executive summary is divided into 4 sections: 1. Planning 2. Existing System 3. Future System 4. Improvements PLANNING The City's service area population and land use trends are major elements affecting water system planning. The service area has been established through agreements with adjacent purveyors using the Skyway Coordinated Water System Plan and East King County Coordinated Water System Plan as the planning vehicles. Service area boundaries will not change without annexation. Most of Renton's neighbors are supplied by the City of Seattle,and are experiencing reductions in water resource allocations. • Renton's service area has been included in the East King County Regional Water Supply Plan, and Renton has been asked to participate in developing regional water supply sources. These sources may not benefit Renton's water supply system. Population projections have a large impact on water supply planning; however, planned land use changes within the service area have a small impact. Water quality and supply reliability standards and policies have the largest impact in facility planning and phasing. In fact, water resource planning and water quality (aquifer) protection should be the highest priorities of the Water Department. EXISTING SYSTEM The existing system is well maintained and provides a high level of service. The system is deficient,however,in booster station capacity to the Highlands 435 and 565 pressure zones, and the West Hill pressure zones, and is deficient in storage in all of the pressure zones except the West Hill Zone. Water quality is high; however, the system is vulnerable to groundwater contaminations. The distribution system has been designed to provide maximum day demands and adequate fire flow to all customers. 1 - 1 CHAPTER ONE i FUTURE SYSTEM The City has an adequate source of potable groundwater resources located within the existing service area. Development of additional groundwater supplies should be pursued as soon as possible, since it is assumed that political and/or economic events will make future development impossible. The City should not compromise their quality or quantity standards because of regional supply inadequacies, and therefore should not rely on the development of regional sources for the future needs of the City. The City should supply all customers located within the service area boundaries. Additional wells, pump stations, reservoirs and pipelines will need to be constructed. IMPROVEMENTS The City should prepare for and authorize a 30-year CIP budget of $65,000,000.00. Improvements include: 12,750 gallons per minute (gpm) of additional well capacity 27,000 gpm of additional booster station capacity - 26 million gallons of additional storage capacity • Additional improvements include construction of watermains to serve new customers and provide adequate fire protection to existing customers, replacement of asbestos cement and steel , watermains, and engineering investigations to meet water quality standards and use the _ available water resources most effectively. The improvement plan will raise Renton's water rates by 12%, 12%, 4%, 6%, and 8% over the next 5-year period. 1 2 CERTIFICATION This Comprehensive Water System Plan for the City of Renton, 1990,has been prepared under the direction of the following Registered Professional Engineers: Richard H.

Chapter Two INTRODUCTION INTRODUCTION The 1990 Comprehensive Water Plan is the comprehensive water supply plan for the City of Renton and contains policies and criteria that affect decisions regarding water service for Renton's water customers. This plan is the result of a study which evaluated the existing water system and developed alternatives for operation and accommodating growth. The improvements identified in this plan are based on the requirements of the Washington State Department of Health (DOH) and City of Renton Policy. The City of Renton adopted its last comprehensive water system plan in 1984. That plan anticipated growth in the system and proposed improvements but did not foresee all issues which have arisen since that time: changes in water resource allocation, changes in water quality standards, significant increases in construction cost, land use densities, and population projections. These issues and others are examined in detail in this Comprehensive Plan. The Renton water system is large and, because of the topography, it is difficult to understand and operate. The condition of the current system, as well as the need for improvements in a level of detail that will satisfy most readers, has been documented. However, due to the magnitude of this system and the number of issues that must be addressed, this report is organized so that a reader may review a summary of the plan in Chapter 1,without reading the background or detailed information which led to those results. Readers interested in more details should examine the remainder of the report. The plan provides a recognized framework for making decisions about potable water supply in the City of Renton. It is intended to aid users including the Water Utility, City Council members, the Mayor and staff, builders, developers, community groups, and other government agencies. The plan helps these users in several ways. First, the plan is the framework for improvements and operations that govern water system developments in the City's service area. The plan provides a basis for allocating improvements and costs to new, additional water users in the system, such as home and apartment builders and commercial developers. It thus provides City officials with partial direction for approving building permits and upgrading the system. Second, the plan provides a guideline for improving the existing system to supply each customer with adequate supply and acceptable quality water. It is intended that City officials will be able to use these guidelines as supply and quality standards change, to maintain the highest quality service at the least cost. Finally,the plan provides a basis for accommodating changes that occur butthat cannot be forecast in the plan. To this end, the plan lists policy issues and operational criteria that can be used to develop alternatives and direction for development, improvements, and operations. 2 . 1 CHAPTER TWO Several members of the City staff possess an exceptionally detailed understanding of the City's water system, and have provided valuable input for this plan. Mr. Ron Olsen, Mrs. Arlene Haight, Mr. Ray Sled and Mr. Jack Crumley are thanked for their assistance. HOW TO USE THIS PLAN This plan is arranged in eight major sections. Chapter 3 identifies the existing facilities,and documents the history of the water utility. Chapter 4 documents the condition of the existing facilities, discusses land use and adjacent systems. Chapter 5 examines demands for existing conditions as well as anticipated future conditions. Chapter 6 documents current and planned water supplies to meet the demands listed in Chapter 5. Chapter 7 identifies the policies and design criteria for the water utility. Chapter 8 examines the condition and performance of the existing system in accordance with the accepted policies and criteria through system analysis. Chapter 9 identifies improvements necessary to comply with policy requirements, law, and anticipated future conditions. Chapters 10 and 11 examine the operations, maintenance and financial characteristics of the utility. 2 - 2 Chapter Three EXISTING SYSTEM 1. SYSTEM OVERVIEW The City of Renton's Water System provides service to an area of approximately 16 square miles and more than 11,000 customers. In addition, the City supplies water on a wholesale basis to Lakeridge Bryn-Mawr Water District through a single metered connection. The water service area is shown in FIGURE 1. Water supply sources include six wells and one artesian spring that are used for normal supply, and five metered connections to Seattle's Cedar River and Bow Lake supply pipelines that are used for emergency back-up supply only. All of the wells are located in the area of Cedar River Park and Liberty Park, and pump from a relatively shallow aquifer. These wells provide 96% of the City's supply capacity. The water distribution system serves the valley floors and parts of five surrounding hills: the West Hill, the Highlands, Scenic Hill, Talbot Hill and Rolling Hills. All of the water from the wells and the artesian spring is first pumped into the lowest pressure zone in the valley floor, and then pumped up these four hills for consumption. As a result of this topography, the City has 12 hydraulically-distinct pressure zones. Pumping is accomplished by seven booster pump stations that are located throughout the City. Two additional pump stations supply water to the Rolling Hills service area from the Seattle Cedar River transmission pipeline. All water consumed in Renton's service area must pass through at least one and potentially several pump stations. Because of this, the City's system is maintenance-intensive, with facilities for pumping, water quality control, and emergency power generation. Currently there are six reservoirs in the system, and a seventh reservoir under construction. The reservoirs are strategically located throughout the system to provide adequate equalizing and fireflow reserves. Pressure-reducing valves are used to supply lower pressure zones from higher pressure zones that contain water storage reservoirs. The water system is complicated, and is difficult to understand and operate efficiently. The key in this understanding is appreciating the need for the different pressure zones. The zones are necessary to provide reasonable pressures in the distribution system. The City currently serves customers within an elevation range of 30 feet to 500 feet. This range alone results in at least four separate pressure zones. Physical barriers such as hills and valleys often prevent the extension of a pressure zone from one location to another. As an example, the pressure zones 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. Thus, Maple Valley has provided a physical barrier which has precluded joining of hydraulically-similar pressure zones. As a result of these physical barriers and the elevation range served, the pressure zones are necessary. All of the pressure zones are hydraulically interrelated with the lowest zone in the Valley floor, the 196 Zone. All supply to the system,if not consumed in the downtown 196 zone, is pumped 3 - 1 CHAPTER THREE to a higher zone where it is used primarily to supply residential and commercial demands. In the City's system, water moves up through the pump stations and down through the pressure reducing valves. FIGURE 2 shows a hydraulic profile of the existing system and demonstrates how water moves vertically through the water system. FIGURE 1 shows how water moves horizontally through the system. It is desirable to have two or more connections (or supply points) that will allow water to move upward to a higher pressure zone or downward to a lower pressure zone. This maximizes system reliability by providing multiple paths or routes that the water can take when moving between pressure zones. At first glance,it appears that the Renton system is ideally constructed,since each pressure zone has at least two sources of supply. This is not the case, however. Renton has several problems that are unique because of its geographical characteristics: 1) Some facilities are in poor hydraulic locations, which require the addition of a third or even fourth source of supply, 2) Renton is wholly dependent on supply from a single, shallow aquifer that is vulnerable to contamination, and 3)water which recharges Renton's aquifer may be diverted for use by other water users. The remainder of this chapter is devoted to an examination of the existing water facilities, and the improvements which have been made since the 1983 Comprehensive Plan. 2. IMPROVEMENTS SINCE 1983 The history of the City's System is well documented in the previous Comprehensive Water System Plans prepared for the City by CH2M Hill in 1965 and RH2 Engineering in 1983. That particular information is not repeated in this document. For those interested,the 1965 and 1983 Comprehensive Water System Plans are available from the City. Numerous changes to the water system have occurred since the completion of the 1983 Comprehensive Water System Plan. The major changes are summarized below. Source of Supply Development and construction of Well No. 9. Development and construction of Replacement Wells 1, 2, and 3. Placement of Well No. 3 in a standby status. Redevelopment of Well No. 5. Development of Well Nos. 11 and 17. All of the West Hill and a majority of the Rolling Hills and Talbot Hill areas were converted from Seattle supply to City supply. Performed exploratory drilling in Maplewood area. 3 - 2 • i-_ Existing System Storage Construction of the 1.4 million gallon (MG)West Hill Reservoir. Construction of the 1.5 MG South Talbot Hill Reservoir. Booster Pump Stations Construction of the West Hill Booster Pump Station. Replacement of the motor control center and motor starters for the Mount Olivet and Highlands Booster Pump Stations. Rehabilitation of the Tiffany Park Booster Pump Station. Pressure-Reducing Stations (PRV) Construction of one PRV Station(No.20)to the Renton Scenic Hill 490 Pressure Zone and one PRV Station (No. 22) to the Renton Scenic Hill 370 Pressure Zone. Construction of four PRV stations to the North Rolling Hills 490 Pressure Zone, one PRV station to the Talbot Hill 350 Pressure Zone,and one PRV station to the West Talbot Hill 300 Pressure Zone. Construction for the Marina Landing Apartment Project of one PRV station to the Kennydale-Marina Landing 320 Pressure Zone and one PRV station to the Downtown 196 Pressure Zone. Interties Construction of an intertie with the City of Tukwila. Construction of a new emergency intertie with Seattle near Longacres. Construction of an intertie with the City of Kent. Transmission and Distribution Pipeline Additions Construction of the West Hill Transmission Pipeline from the West Hill Pump Station to the former KCWD No. 63, now Lakeridge Bryn-Mawr Water District. Construction of the Longacres Transmission Pipeline. Construction of the Maple Valley Transmission Pipeline to the Maplewood Golf Course. Construction of the Oaksdale Transmission Pipeline. Construction of the 24" Transmission Pipeline from Wells 1, 2 and 3 to South 4th Street. 3 . 3 CHAPTER THREE Development of a stronger pipeline grid in the southwest industrial area of the Downtown ' 196 Pressure Zone. Developer extensions throughout the system which have improved the grid capacity. Looping of deadend pipelines in order to improve grid capacity and system reliability. Source Treatment New or rebuilt chlorination treatment facilities have been installed at all sources of supply for the City. Fluoridation treatment has been provided for each of the City's supply sources. Telemetry and Supervisory Control A new telemetry and supervisory control system has been installed for the water system. The system uses hard wire and radio transmission for communication between the various components within the water system. Telemetry conduit and wiring was installed which connected City Hall, Well Nos. 1,2, 3, 8, and 9, Mount Olivet and Monroe Street Booster Pump Stations, and the City's Maintenance Shop. 3. PRESSURE ZONES The System is divided into 12 different pressure zones for the purpose of providing reasonable pressures in the distribution system. The City currently serves customers within an elevation range of 30 feet to 500 feet. This range alone results in at least three pressure zone divisions and, therefore, four separate pressure zones. Physical barriers such as hills and valleys often prevent the extension of a pressure zone from one location to another. As an example, the pressure zones 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. Thus, Maple Valley has provided a physical barrier which has precluded joining of hydraulically similar pressure zones. As a result of these physical barriers and the elevation range served, there are 12 pressure zones in the City's System. TABLE 3-1 lists each pressure zone, as it is commonly named, and the nominal hydraulic elevation that each ressureprovides.p zone p ovides. The nominal hydraulic elevation is the overflow elevation of the highest reservoir in the pressure zone or the elevation that a reservoir would have if there was a reservoir in a zone which currently does not have one. Also included in TABLE 3-1 are the lowest and highest ground elevations served in each pressure zone and the corresponding pressure at.those locations. 3 - 4 • Existing System TABLE 3-1 PRESSURE ZONES Maximum Minimum Minimum Maximum Elevation Service Elevation Service Served Pressure Served Pressure Pressure Zone (feet) (psi) (feet) (psi) Kennydale 320 210 48 15 132 Highlands 435 320 50 100 145 Highlands Elevated Tank 565 415 65 300 115 • Downtown 196 100 42 15 78 West Hill 495 350 63 150 149 West Hill 270 190 35 50 95 Scenic Hill 370 200 75 100 117 Scenic Hill 490 380 48 200 126 Talbot Hill 590 455 58 300 126 Talbot Hill 490 400 39 200 126 Talbot Hill 350 250 43 125 97 Talbot Hill 300 175 54 50 108 NOTE: Pressures stated above are static values. FIGURE 2, The System Hydraulic Profile, shows the vertical relationship of the System's pressure zones and demonstrates how water can move up or down through the System. In the Renton System, water moves up through booster pump stations and down through pressure reducing stations. The hydraulic profile illustrates how water can move vertically through the System, while FIGURE 1 illustrates how water can move horizontally through the System. All pressure zones are served directly or indirectly from the City's active wells and Springbrook Springs. All of this supply, if not consumed in the Downtown 196 zone, is pumped to a higher zone where the water is primarily used to supply residential and commercial demands. As an example, water consumed in the Highlands Elevated Tank 565 zone is first pumped from the aquifer at the wells into the Downtown 196 zone,then pumped into the Highlands 435 zone,and then pumped again to the Highlands Elevated Tank 565 zone. Another example is the route that water follows to supply the Kennydale 320 zone. This supply comes from the Downtown 196 zone,is pumped up to the Highlands 435 zone,and pressure-reduced to the Kennydale 320 zone. The remaining routes for supply to each zone can be traced by following the connections shown on FIGURE 2. It is necessary to have two or more connections (or supply points)that will allow water to move to a higher pressure zone, or downward to a lower pressure zone. This procedure maximizes system reliability by providing multiple paths or routes that the water can take when moving between pressure zones. 3 - 5 CHAPTER THREE In the Renton water system, some supply facilities are located in areas that are poor hydraulic locations, and others are located so that a single failure mechanism can take all of the supply sources out of service. In these instances, more than two sources may be necessary. These issues will be addressed in subsequent chapters. Although the system has 12 distinct pressure zones, not all of the zones have separate storage or supply facilities. Some zones are supplied exclusively by pressure-reducing stations from an upper zone that contains storage and pump stations. It is impractical to plan facilities and improvements for all of these zones; therefore, the water system has been divided into five operating areas. Each operating area is a single zone or combination of zones with similar operating characteristics. For example, a lower zone that is supplied exclusively by PRVs from an upper zone would be combined with that upper zone to form an operating area. For the majority of this plan, the following zones are included in each operating area: Operating Area Included Pressure Zones 196 Downtown 196 Zone 435/320 Highlands 435 Zone Kennydale 320 Zone 565 Highlands 565 Zone West Hill West Hill 495 Zone West Hill 270 Zone - - Rolling Hills/Talbot Hill Rolling Hills 590 Zone Rolling Hills 490 Zone Talbot Hill 350 Zone Talbot Hill 300 Zone Renton Hill 370 Zone Renton Hill 490 Zone At saturation it is anticipated that the Kennydale 320, Rolling Hill 490, and Talbot Hill 350 zones will have separate storage and supply facilities, and they will therefore form their own operating areas. In an attempt to minimize confusion, however, they are consistently referred to in the above listed operating areas for this plan. 4. SUPPLY FACILITIES Water supply within the service area is from wells and one artesian spring. This section provides a description of the function of each supply facility. The recommended sizing and location of additional facilities are presented in Chapter 9. 3 - 6 Existing System Well Facility Nos. 1-2-3 (RW1, RW2, RW3) The well facility, constructed in 1988, is an above-grade structure constructed from tilt-up concrete walls and a steel structured roof. The well facility is located in Liberty Park adjacent to Houser Way and the Cedar River. The well building is divided into seven rooms. The main pump room contains the three well pumps,the motor control center,and the flow meters. Other rooms include fluoride feed,fluoride storage, chlorine feed, and chlorine storage. Two rooms are currently vacant. The well facility is in excellent condition. The well provides direct service to the Downtown 196 pressure zone and is automatically controlled by the level in the Talbot Hill reservoir. The well facility has three deep well pumps with electric-powered motors. The capacity of each pump and motor is 2,400 gallons per minute(gpm);however,the wells are throttled to 2,200 gpm by the use of a control valve. Each well has an independent flow meter which is located in the pipe gallery within the pump room. Each well pumps to a common header which connects to the 24" diameter transmission pipeline located south of the well building. Well Facility No. 3 (PW3) The well facility,constructed is 1959,is an underground concrete vault which encloses the pump and motor, flow meter and motor control center. The well is located in Liberty Park on the southwest cornerof the intersection of Houser Way and Bronson Way. Adjacent to the buried vault is an above-grade concrete block (CMU) building which houses the chlorination and fluoridation equipment for the well. The well facility is on standby status and is only used under emergency conditions. The water rights for this well are in the process of being transferred to the City's replacement Well No. 3, located with Well Nos. 1 and 2. If the well was to be used on a regular basis, some modifications and improvements would be necessary. Access to the well is difficult, and the vault can fill with water rapidly if the pump were to fail. The well provides direct service to the Downtown 196 pressure zone and is automatically controlled by the level of the Talbot Hill reservoir. The well facility has one deep well pump with an electric-powered motor. The capacity of the pump and motor is 1,500 gpm. The discharge pipe from the well extends east and connects to the transmission pipeline in Houser Way. Well Facility No. 8 (PW8) The Well facility,constructed in 1967,is an above-grade structure constructed from architectural brick. The well is located in Cedar River Park adjacent to Interstate 405. The well building is divided into two rooms. The chlorination room is located in the north side of the building and the well pump and motor room is located in the south side of the building. The well facility is in good condition and is reliable; however, consideration should be given to replacing the motor control center since this does not comply with current codes. 3 - 7 CHAPTER THREE 1 The Well provides supply to the Downtown 196 Pressure Zone, and is automatically controlled by the level in the Talbot Hill reservoir. The Well facility has one deep well pump with an electric-powered motor. The capacity of the pump and motor is 3,500 gpm. The 12" diameter discharge pipe for the well extends east and connects into the 24" diameter transmission pipeline. The flow meter is located outside the pump facility in a buried, rectangular concrete vault. Well Facility No. 9 (PW9) The well facility,constructed in 1986,is an above-grade structure constructed from architectural brick and a pre-formed metal roof. The well is located in Cedar River Park adjacent to Interstate 405. The well building is divided into three rooms. The chlorination room is located in the north - side, the well pump and motor control center room is located in the middle, and the well field telemetry room is located on the south side of the building. The well facility is in good condition and is reliable; however, during peak summer demands the draw down in the well casing can reach the pump intake, requiring the pump to be throttled to a lower flow rate. The well provides direct service to the Downtown 196 pressure zone and is automatically controlled by the level in the Talbot Hill reservoir. The well facility has one deep well pump with an electric motor. The capacity of the pump and motor is 1,250 gpm. The 12" diameter discharge pipe for the well extends south and connects to a 24" diameter transmission pipeline. The flow meter is located outside the pump facility in a buried concrete vault. Springbrook Springs (Springs) The Springs facility was originally constructed in 1909 and the latest rehabilitation was completed in 1976. The Springs has two infiltration galleries which collect water and channel it into the transmission pipeline. Several drainage bulkheads prevent surface water from entering the infiltration galleries. The City has acquired ownership of a significant amount of property to form a watershed directly surrounding the Springs. A chain-link fence has been erected around the property to restrict access to and activities within the watershed. A chlorination and fluoridation building, constructed in 1987, is located approximately 300 yards from the infiltration galleries adjacent to the transmission pipeline. The Springs provides direct service to the Downtown 196 pressure zone by flowing directly to the Talbot Hill reservoir. The level in the Talbot Hill reservoir provides the only control of the discharge from the Springs. The Springs facility is a free-flowing facility with no control of its discharge rate. In its past,the Springs has had a capacity of near 1,200 gpm; however, the supply rate has recently been reduced to between 300 and 500 gpm. The flow meter is located inside the chemical treatment building. This treatment building also contains the equipment for the fluoridation and chlorination of the water. It is possible that a rehabilitation of the springs will increase the production to the water right capacity. 3 - 8 • Existing System Well Facility No. 4 (Inactive) Well No. 4, formerly Highlands Well No. 1, was originally constructed for the Northwest Water Company before the Highlands area was annexed to the City. The Well has a capacity of 100 gpm,and was used until the early 1960s to introduce chlorine into the then uncovered Highlands Reservoir. When the reservoirs were covered, the need for chlorination was eliminated and the well was abandoned. The building was razed and the well capped. The City has an active water right of 170 gpm at Well No. 4. Well Facility No. 5 (Inactive) Well No. 5 was drilled in 1953, and operated satisfactorily until 1959, at which time the well. developed a sand production problem. In addition, many water quality complaints due to taste and odor were received. The use of this well was discontinued in 1965. The well was redrilled in 1988, and design of a new well pumping and treatment facility is currently under way. The City currently has active water rights of 1,500 gpm at Well No. 5. When this well is completed, it will be referred to as "Well 5A". Well Facility Nos. 11 & 17 Well Nos. 11 and 17 are new wells that were drilled in 1988 and 1989. The City is currently seeking water rights of 2,500 gpm for Well No. 11, and 1,500 gpm for Well No. 17. Design of the well pumping and treatment facilities is currently underway.

WATER TREATMENT FACILITIES Renton chlorinates and fluoridates all of the well and spring water supplied to the water system. Vacuum-type gas chlorinators are installed at each active well and at Springbrook Springs. The gaseous chlorine is combined with the well water on the discharge of each pump based on the actual pump flowrate to maintain 0.8 parts per million (ppm) chlorine residual in the water. Each chlorination facility is contained in a separate room from the well mechanical and electrical equipment to minimize corrosive effects. In addition, at Springbrook Springs and Well Nos. R1, R2, and R3, the chlorine cylinders are stored separately from the gas chlorination injection equipment. This provides a safer and longer lasting installation. Each chlorine facility is equipped with an emergency cylinder repair kit and self-contained breathing apparatus in accordance with Washington State Department of Health (DOH) standards. The chlorine storage and feed rooms at Well Nos. R1, R2 and R3 are also equipped with chlorine gas scrubbing facilities to contain a gas leak and prevent chlorine gas from escaping from the rooms during a chlorine leak. The scrubbing facility complies with the latest NFPA standards for chlorine leak containment. In the event of a leak at any location, the Renton Fire Department is responsible for emergency evacuation and containment. Water Department personnel do not participate in emergency leak repair operations. All sites are equipped with remote gas leak alarms. A chlorine feed station is also located at the Highlands reservoir site and can be used to inject chlorinated water directly into the 435 Zone reservoir when chlorine residuals in this area of the City are low. It is currently difficult to maintain acceptable chlorine residual levels in the West Hill Reservoir and in the distribution system surrounding Valley General Hospital. The Hospital is sensitive to water quality because of the ultra-fine filters used in some of their lab processes. On August 26, 1985, the City Council adopted Ordinance No. 3932 requiring the addition of fluoride to the City's well and spring water. Three facilities are currently in use to provide a 1 ppm fluoride level in the system. A storage and chemical feed building in Cedar River Park supplies both Well No. PW8 and PW9, and is located halfway between the two well buildings. This facility also serves as the terminal storage location for fluoride supplies and chemicals,and can house enough sodium fluoride to supply the water system for six months. A separate building at Springbrook Springs houses both fluoridation and chlorination equipment and is equipped with enough storage space to store sodium fluoride for one month of supply. A storage and separate feed room are located in the well building at Well Nos.R1,R2, and R3 and supplies all three wells at this location. The fluoride injection process uses sodium fluoride crystals that are dissolved in softened water in a small tank called a saturator to produce a 4% fluoride/water solution. The saturated solution is piped to a storage tank(day tank) of sufficient capacity to supply each site with 24 hours of fluoride supply. The fluoride solution is pumped out of the day tanks into an injector in the discharge of each well pump (or spring) based on the pump flowrate to maintain appropriate residuals in the water system. This system is cost-effective, reliable and relatively safe. Each site is equipped with a bag feeding device which allows the operator adding sodium fluoride crystals to the saturator tanks minimal exposure to sodium fluoride dust, a corrosive chemical. 3 - 11 CHAPTER THREE Each site is also equipped with an emergency eyewash and shower in the event of a worker contamination. Spent bags are washed with water to stabilize the remaining sodium fluoride dust and disposed of in a regulated hazardous material disposal site. The fluoride day tanks are alarmed for low level conditions, and a spare chemical metering pump is provided at each site. 6. STORAGE FACILITIES Water storage within the distribution system provides for equalizing storage and standby storage for fire-fighting and emergency reserves. Storage is provided by reservoirs and elevated tanks located within the distribution system. The City currently operates seven storage facilities. This section provides a description of the function and conditions of each of these facilities. The recommended sizing and location of future storage facilities are presented in Chapter 9. Downtown 196 Zone Storage The Downtown 196 Zone has two reservoirs, the Talbot Hill Reservoir and the Mount Olivet Reservoir. Constructed in 1976,the Talbot Hill Reservoir is a cast-in-place concrete,ground-level reservoir with a capacity of five million gallons and an overflow elevation of 196 feet. The Mount Olivet reservoir, constructed in 1967, is an above-grade steel reservoir with a capacity of 3 million gallons and an overflow elevation of 186 feet. Since the overflow elevation is 10 feet lower, the Mount Olivet Reservoir is equipped with an altitude valve to allow the Talbot Hill Reservoir to be filled without overflowing the Mount Olivet tank. Both reservoirs are supplied by water from Wells RW1, RW2, RW3, 3, 8, and 9, and Springbrook Springs. These reservoirs are in good condition, although the interior of Mt. Olivet needs to be recoated. Highlands 435 Zone Storage The Highlands 435 Zone has two cast-in-place concrete,ground-level reservoirs which are located adjacent to each other and act as a single reservoir with a total capacity of 3.5 million gallons (2.0 and 1.5 MG, respectively), and an overflow elevation of 435 feet. These reservoirs provide storage for the Highlands 435 and Kennydale 320 Zones. They are supplied with water from the Mount Olivet and the Windsor Hills Booster Pump Stations. Highlands 565 Zone Storage The Highlands 565 Zone has one reservoir,which is an elevated steel tank and is located on the same site as the Highlands 435 reservoirs. The tank,which has an overflow elevation of 565 feet and a capacity of 0.75 million gallons, provides storage for the Highlands 565 Zone and is supplied water from the Highlands and the Monroe Avenue booster stations. This reservoir was last repainted in 1978 with a graphic design. Rolling Hills 590 Zone Storage The Rolling Hills 590 Zone has one reservoir, an elevated steel tank with an overflow elevation of 590 feet and a capacity of 0.3 million gallons. The reservoir provides storage for the following zones: Rolling Hills 590, Rolling Hills 490, Talbot Hill 350, and Talbot Hill 300. The reservoir is supplied by the North Talbot Hill Pump Station. The tank has inadequate capacity to serve this much area and, in effect, operates only as a hydraulic control surface for the pumps that 3 - 12 Existing System supply the 590 Zone. The tank is supplied by the North Talbot Hill pump station, and also by the Tiffany Park and Fred Nelsen Pump Stations from the Seattle transmission mains. West Hill 495 Zone Storage The West Hill 495 Pressure Zone has one reservoir, a steel standpipe with an overflow elevation of 495 feet and a capacity of 1.4 million gallons. The reservoir was completed in 1985, and provides storage for the West Hill 495 and 270 pressure zones and the Lakeridge Bryn-Mawr Water District. The reservoir is supplied by the West Hill Booster Pump Station, and can be supplied by a 6" metered connection on the Seattle transmission main (with an estimated maximum static head of 460 feet). South Talbot Hill 350 Zone Storage The South Talbot Hill 350 Pressure Zone has one reservoir, which is scheduled to be completed and on-line by March of 1990. The reservoir has a capacity of 1.5 million gallons and is supplied water by the South Talbot Hill Pump Station and various PRVs from the upper 490 and 590 pressure zones. 7. DISTRIBUTION SYSTEM The City's water pipelines are shown in plan view in FIGURE 1. Transmission capability for the System is primarily provided by 12", 16" and 24" diameter pipelines from the well field located in Liberty Park.and Cedar River Park to various points within the service area. Since approximately 95% of the System's supply is provided from this well field, major transmission facilities are required in the 196 Pressure Zone to ensure adequate water distribution throughout the service area. As can be observed in FIGURE 1, the transmission pipelines are located primarily along the major transportation corridors. Some transmission capability is also provided by the looped 8" diameter pipelines in the well developed residential areas of the system. Transmission pipelines in the 196 pressure zone predominantly run north to south, supplying the downtown business zone,the Green River Valley industrial complexes,and the booster pump stations which serve the other areas of the system. Additional transmission capacity is also provided by east-west pipelines that connect to the north-south transmission mains. The pipe loops or grids formed by these connections help to increase System reliability and capacity throughout the system. 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 Pump Station to the reservoir. A separate transmission route connects the reservoir with Lakeridge Bryn-Mawr Water District. A large percentage of the transmission capacity in the West Hill area is provided by looped 8" and 6" distribution mains. The distribution system for the City as shown in FIGURE 1 consists of all the smaller pipelines below 12" in diameter that convey water from the transmission grid to the individual service 3 - 13 CHAPTER THREE connections. A distribution system functions by meeting individual demands in the immediate vicinity via branching and looping pipelines through the service area. TABLE 3-3 summarizes pipe lengths by size in the water system. i TABLE 3-3 PIPE INVENTORY BY PRESSURE ZONE WEST ROLLING/ 435/320 HILL TALBOT PIPE 196 ZONE ZONE 565 ZONE ZONE HILL ZONE TOTAL SIZE (feet) (feet) (feet) (feet) (feet) SIZE (feet) 4" 7,225 27,630 14,130 7,900 19,090 75,975 6" 24,980 54,939 73,099 12,010 42,181 207,209 8" 26,000 44,753 83,846 23,875 62,172 240,646 10" 12,015 8,335 18,635 3,925 6,165 49,075 � 12" 83,884 38,021 30,236 9,335 51,946 213,422 16" 21,470 19,120 2,645 -- 8,585 51,820 20" -- 710 -- -- -- 710 24" 11,615 -- -- -- -- 11,615 TOTAL 187,189 193,508 222,591 57,045 190,139 850,472 Transmission mains generally convey water between the supply sources (reservoirs or wells) to the local distribution grid where it is conveyed to the source of the demand. Ideally, minimal head losses 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. Under normal condition the velocity of water in either transmission and distribution mains should be less than five feet per second(fps) during peak demand periods, and less than 8 feet per second during fire demands periods. Velocities in excess of 8 feet per second may produce unacceptable thrust forces in underground fittings and cause excessive pipe wear or failure; therefore, 8 FPS should be used as a design criteria. The transmission and distribution system is comprised of watermains manufactured of four different materials: Asbestos Cement (AC), Steel, Ductile iron, and cast iron. Current City policy is to replace all AC and steel watermains in the system as the budget permits,since these materials are prone to leak and fail. FIGURE 7 shows the AC and steel pipe in the system. 8. BOOSTER PUMP FACILITIES The City currently owns and operates nine booster pump stations which boost water from the City's lower pressure zones to the upper ones. All supply to the upper pressure zones is provided 3 - 14 Existing System by booster pump stations. Fireflow requirements are met using a combination of supply from booster stations and storage in upper zones, ratherthan providing oversized capacity in the booster pump stations to meet this unusual condition. The Kennydale 320 and Talbot Hill 300 and 490 zones are the only zones in the System that currently have supply which has been pumped to an upper zone and then pressure-reduced from that upper zone. Major improvements since the 1983 Comprehensive Plan include the addition of the West Hill Pump Station, extensive rehabilitation of the Tiffany Park Pump Station, and new telemetry equipment for each of the City's pump stations. In addition, two pump stations, Mt. Olivet and Highlands, have been equipped with new electrical equipment. The functions and conditions of the booster pump stations in the City are described in the following paragraphs. Appendix A provides a functional summary for each pump station. Recommended improvements can be found in the appropriate section of Chapter 9. Mount Olivet Pump Station (250 Bronson Way NE) The Mount Olivet Pump Station is the lead (first operated) supply for the Highlands 435 pressure zone and normally pumps directly from the Mt. Olivet reservoir. (Downtown 196 pressure zone). The pump station is controlled by the levels in the Highlands 435 reservoirs and operates in conjunction with the Windsor Hills Pump Station. In 1988, new motor starters, a new pump and motor, and a new motor control center were installed, as well as new heating and ventilation equipment. The pump station does not have emergency power generation capabilities. At present, the site is not fenced. Windsor Hills Pump Station (581 Sunset Boulevard NE) The Windsor Hills Pump Station is the lag (second operated) supply for the Highlands 435 pressure zone. The station pumps from the Downtown 196 pressure zone and is also controlled by the levels in the Highlands 435 reservoirs. All water which is consumed in the Highlands or Kennydale area must pass through the Windsor Hills or the Mt. Olivet Booster Pump Stations. This station is in poor condition. The ventilation system is inadequate. The pump station does not have a main breaker inside the building. The electrical equipment, including the motor starters and motor control system, need to be replaced. The pump station does not have emergency power generation capabilities. The location of the station on this unfenced site renders it vulnerable to automobile traffic. Monroe Avenue Pump Station (401 Monroe Avenue NE) The Monroe Avenue Pump Station is the lead supply to the Highlands elevated tank in the Highlands 565 zone and operates in conjunction with the Highlands Pump Station. The station pumps from the Highlands 435 zone and is controlled by the level in the Highlands 565 elevated tank. Pump No. 2 was rebuilt in 1989; however, the station also needs a complete electrical system upgrade. This station is in fair condition. The pump station does not have emergency power generation capabilities. 3 -.15 CHAPTER THREE Although the site is not fenced, no vandalism has been noted at this station. Highlands Pump Station (3410 NE 12th Street) The Highlands Pump Station is the lag supply to the Highlands 565 Zone and pumps from the Highlands 435 zone. The pump station is controlled by the level in the Highlands 565 elevated tank and operates in conjunction with the Monroe Avenue Pump Station. All water which is consumed in the Highlands 565 pressure zone must pass through the Highlands or Monroe Avenue Pump Stations. Emergency backup power for the pump station is provided by a portable generator which is garaged at the site. Operation and control of the backup generator is automatic with the loss of power to the site. Recent improvements include the installation of new electrical equipment, new motor starters, and a new motor control center in 1988. Two of the three pumps and motors were replaced in 1988 to increase capacity and the third pump rebuilt. The station is in fair condition. The suction side of the pumps does not have a valve to isolate the pump station from the system for maintenance and repairs. North Talbot Hill Pump Station (730 South 19th Street) The North Talbot Hill Pump Station has three constant-speed pumps which pump from the Downtown 196 pressure zone to the Rolling Hills 590 pressure zone and are controlled by the levels in the Rolling Hills 590 elevated tank. The pump station also has one variable speed pump which pumps from the Downtown 196 pressure zone to the Talbot Hill 350 pressure zone. This pump is controlled by pressure in the 350 zone. This station is the lead pump station to the 350 zone since it has a variable speed pump, while the South Talbot Hill pump station can provide additional supply when needed. The Tiffany Park and Fred Nelsen Pump Stations operate as backup to the North Talbot Hill Pump Station by providing supply from Seattle. This pump station, which was constructed in 1978, is located adjacent to the Talbot Hill Reservoir and is in good condition. The pump station does not have emergency power generation capabilities. The site is fenced, which provides adequate vandalism protection. South Talbot Hill Pump Station (50 South 43rd Street) The South Talbot Hill Booster Pump Station has two domestic and two fireflow pumps. This station pumps to the Talbot Hill 350 zone from the Downtown 196 pressure zone. Until the 350 zone reservoir is complete, the pumps are controlled by the pressure in the zone. The pump station operates in conjunction with the variable speed pump in the North Talbot Hill Pump Station. The South Talbot Hill Booster Pump Station was constructed in 1982, and is in good condition. The pump station does not have emergency power generation capabilities. The site is not fenced and is, therefore, subject to vandalism. Tiffany Park Pump Station (2000 Kirkland Avenue SE) The Tiffany Park Pump Station pumps from the Seattle Cedar River supply pipeline to the Rolling Hills 590 zone and is operated as a backup to the North Talbot Hill Pump Station. It 3 - 16 • Existing System can be manually or automatically controlled. The pump is controlled by the level in the Rolling Hills elevated tank. The Tiffany Park Pump Station was last rehabilitated in 1984 and is in good condition. The pumps were replaced in 1972 and the building and electrical service were rehabilitated in 1984. The building rehabilitation included a new roof, door, flooring and paint. The site was also landscaped but is not fenced,and vandalism problems have occurred. The pump station does not have emergency power generation capabilities. Fred Nelsen Pump Station (2200 Bensen Road South) The Fred Nelsen Pump Station pumps from the Seattle Cedar River supply lines to the Rolling Hills 590 zone and is operated only in emergencies as a backup to the North Talbot Hill Pump Station. The pump station can be manually or automatically controlled. All supply to the Rolling Hills 590 zone must pass through the North Talbot Hill, Tiffany Park, or Fred Nelsen Pump Station. The Fred Nelsen Pump Station is in poor condition and in need of repair. The lack of access and parking facilities poses a potential safety hazard. The pump station does not have emergency power generation capabilities. West Hill Pump Station (615 Perimeter Road, Renton Municipal Airport) The West Hill Pump Station pumps from the Downtown 196 pressure zone to the West Hill 495 pressure zone. The facility has two domestic pumps and one diesel-powered fireflow pump and is controlled by the level in the West Hill 495 reservoir. The fenced pump station was constructed in 1985 and is in good condition. Kent Intertie The Kent Intertie includes a pump station that pumps from the Renton System to the Kent Water System. It can also pressure-reduce from the Kent system to the Renton system,thereby allowing flow in either direction. The station is entirely underground and is located near the intersection of Southwest 43rd and Lind Avenue. The station is owned by the Kent Water Department and operated within the terms and conditions of an agreement with the City of Renton. 9. PRESSURE-REDUCING STATIONS Pressure-reducing 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 pressure- reducing valves(PRV)in the pressure-reducing station 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 grade line). Lead PRVs should be located hydraulically-remote from both upperand lower zone reservoirs to promote good circulation in both zones and maintain water quality. Lag PRVs may be located 3 - 17 CHAPTER THREE •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 Renton System are as follows: 1. To maintain pressures in the lower 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 zone, thereby maintaining water quality. When a PRV malfunctions in an open position and allows downstream pressures to rise above the PRV setpoint, failures can occur due to overpressuring the zone. The probability of overpressuring the lower zone can be greatly reduced by placing a pressure relief valve on the discharge (pressure-reduced)side of the PRV,a procedure recently implemented by the City for pressure-reducing stations. If a pressure sensor is also installed on the PRV discharge and the pressure reading telemetered and alarmed at the central control center, the City will know quickly when the failure is occurring and be able to minimize damages as a result of the PRV failure. • Appendix A details the characteristics of the pressure reducing stations in the Renton Water System. 10. INTERTIES The City maintains several standby interties that function as facilities which are automatically operated. These standby supply facilities consist of Pump Stations and Pressure-Reducing Stations that are supplied by the City of Seattle, and that can be operated automatically. They include the Tiffany Park Pump Station, Fred Nelsen Pump Station, West Hill Supply Stations, Scenic Hill Supply Station/PRV, and the South Talbot Hill PRV. The Tiffany Park and Fred Nelsen Pump stations are located in the Rolling Hills area in Southeast Renton and pump directly to the Rolling Hills 590 pressure zone. They are rated for 1,050 and 925 gallons per minute,respectively. Both stations are normally operated as lag standby supplies;however,they are equipped with automatic control equipment and are automatically started and operated if demands are larger than the remaining supply to the 590 zone. The West Hill supply station is a 6" metered and valved connection to the Cedar River Transmission mains and is normally in the off position. The Station must be manually opened and can supply as much as 1,100 gallons per minute to the West Hill area at a 460 hydraulic elevation. The Scenic Hill supply station consists of one 4" pressure-reducing station and one 6" intertie. The PRV operates automatically; however, the intertie must be manually operated. Together these stations can supply 1,800 gallons per minute. The South Talbot Hill PRV automatically opens to supply the 350 pressure zone in the Talbot Hill area and is rated at 1,500 gallons per minute.

PRV 6 Well 3 Park Nelson Hill Talbot PRV Hill PRV • 3 - 19 CHAPTER THREE The City has several emergency intertie facilities as backup to the standby intertie supply system. Emergency facilities include in-service interties and zone valves from an adjacent water system. Some of these facilities have formal agreements and conditions for operation; others do _ not. In-service interties with agreements are maintained with the Cities of Kent and Tukwila. The Kent intertie is located at the intersection of SW 43rd and Lind Avenue South and is connected to Kent's 220 pressure zone. Flowrates from this intertie are approximately 1,000 gallons per minute. The Tukwila intertie is located at SW 37th and the West Valley Highway and is connected to Tukwila's 360 pressure zone. Because of the large differential in pressure, this intertie has a nominal capacity of 5,000 gallons per minute. Tukwila has recently adopted policies that require intertie users to pay Tukwila's demand metering charge if it is incurred while using an intertie. The Tukwila intertie is indirectly supplied by the City of Seattle. Four additional emergency facilities do not currently have operating agreements,but can be used during extreme emergencies for supply. It is presumed that every attempt will be made to negotiate an operating agreement prior to the use of these facilities. An emergency fireflow PRV is located at the Longacres Race Track adjacent to the new stable building, and connects Renton's 196 zone with the Bow Lake supply lines. This PRV is normally used to supplement fireflow in the paddock area, but can be used to supply the 196 zone with as much as 2,000 gallons per minute. A zone valve between the 196 zone and Boeing's fire system in the Northeast corner of Renton Air Field could be used to supply 1,200 gallons per minute to the 196 zone. The fireflow system is supplied by Seattle. A zone valve between Lakeridge and Bryn Mawr in the West Hill area, adjacent to the West Hill Reservoir, will supply 800 gallons per minute. In addition, portable and temporary interties can be constructed between any of Renton's adjacent water systems by connecting adjacent fire hydrants. Because of the large number of possible connection locations and configurations, specific flow rates for these are not listed. TABLE 3-5 lists supply rates available from emergency facilities. TABLE 3-6 and TABLE 3-7 are summaries of on-line supply, standby supply, and emergency supply for the water system. 3 - 20 1 • Existing System TABLE 3-5 EXISTING EMERGENCY SUPPLY FACILITY SUPPLY RATE SUPPLY RATE (GPM) (MGD) Kent Intertie 1,000 1.44 Tukwila Intertie 5,000 7.20 Longacres Intertie 2,000 2.88 Boeing Interde 1,200 1.73 Lakeridge Interde 800 1.15 TOTAL 10,000 14.40 6,000 5,000 �Nh ud IJ��IINIII ll) lydl OW rN 111,411111111 I'I11,1 1m1111!4H,li',4C!MI'!IIIP i'eg i' "IgeR 4 000 Ih I Ij [,;; lir111114'11,"�Gl hYlydk a.

CHAPTER THREE 11. AUTO CONTROL The City currently owns and operates a digital signal based telemetry and supervisory control system manufactured by Uniface, Inc. The system includes a master control center that is located in the City shops and controls the operation of every well and booster pump in the distribution system. The master console interrogates each well, booster station, and reservoir in the system in a timed polling sequence. Each poll takes approximately 1 second. Data is gathered from the reservoirs in the system, and this information is used with operator-selected setpoints to automatically start and stop the appropriate supply pumps. The operator can override the automatic setpoints at the master console, and manually start or stop each pump from the shop location. In addition to this supervisory control function, each remote site is equipped with distributed automatic control equipment called a remote telemetry unit (RTU) that provides local control capability. Each RTU is programmed to stop a pump under conditions that will damage the pump equipment or create a hazard for personnel. This configuration provides the convenience of central control with the reliability of local control. This control system was installed in 1986, as the first phase of a 5-phase improvement plan for automatic control of the system. The master control console uses a combination of radio telemetry and buried cable to communicate with each remote location in the system. • The radio-controlled sites use the 173.2875 mHz radio band for utility data transmission. Each remote site is equipped with a low-power radio transceiver and uni-directional antenna. The master console uses the same low-power radio with a pole-mounted omni-directional antenna located to the west of the maintenance shop building. Communication with the radio-controlled sites has been reliable, although several startup problems were encountered in the first six months after installation. The radio sites include: Highlands Pump Station, Highlands reservoir,Windsor Hills pump station,North Talbot Hill pump station, South Talbot Hill pump station, West Hill reservoir, Rolling Hills reservoir,Talbot Hill reservoir, Springbrook Springs, Tiffany Park pump station, and the Fred Nelson pump'station. The remaining sites in the system use a City-owned 'and installed buried telemetry cable for communication. The cable is installed in an underground conduit system. Communication with the cable-connected sites has been very reliable. Although a cost comparison between the radio and cable sites has not been performed, the City prefers to use the cable where possible. This approach provides the City with complete and single source control over the automatic control system, since the radio system could be taken out of service by a radio user on the wrong frequency. The City currently is in the process of converting radio sites to cable sites at those locations where they can use existing City-owned traffic conduit,or where conduit extensions are economically feasible. In addition, the City requires the installation of empty conduit along i selected pipeline routes during pipeline construction. These routes can be used in the future to connect, or partially connect, radio telemetry sites. The existing cable connected sites are: Monroe Avenue pump station,Mount Olivet pump station,Well Nos. RW1,RW2,RW3, 3, 8 and 9, Mount Olivet reservoir, and City. Hall. The West Hill pump station is connected to the West Hill reservoir by buried cable;however,both sites use the radio to communicate with the master console. 3 - 24 Existing System Each well in the system is automatically controlled by the master console based on levels in the Talbot Hill reservoir. In addition, each well is locally controlled by discharge pressure, and well level is locally shut down if the pressure or level is outside of the normal operating limits. Well flowrate is displayed and recorded on the master console. Each booster station in the system is automatically controlled by the reservoir which it supplies, through the master console. In addition, each well is locally controlled by suction and discharge pressure. If the pressure is outside the normal operating limits, the booster is shut down. Flowrate is displayed and recorded on the master console. Each reservoir in the system is connected to the master console, and its level is used to control one or more booster pumps or wells. One exception to this is the Mount Olivet reservoir in the 196 pressure zone. This reservoir is not normally used to control the well pumps,but rather the level in the Talbot Hill reservoir. Both reservoirs are in the same pressure zone. Reservoir level is displayed and recorded at the master console. Pressure-reducing valves are not currently equipped with automatic control equipment or telemetry capability. Automatic chlorination and fluoridation equipment located at each well and Springbrook Springs is controlled by equipment located at each remote site based on flowrate. No central or supervisory control exists for this equipment; however, the distributed control layout has provided a high degree of reliability and flexibility. The master control console currently records reservoir level, well flowrate, and booster station flowrate on strip chart recorders. Well levels are recorded on a strip chart recorder in Well No. 9. The City has found it inconvenient to collect the recordings from Well No. 9, and maintenance on this part of the system is not consistent. In addition to the strip chart recordings,the City's maintenance staff manually records the time and type of each alarm at the master console, and the daily flow total at each well and booster station. The total flow readings are taken from the mechanical registers on the flow meters, and are used to double-check the flow totals on the telemetry electronics. Improvements Since 1983 All of the control equipment in the system has been replaced since the 1983 comprehensive plan. The installed equipment represents Phases 1, 2 and 3 of a 5-phase automatic control system addition. As a result of the recommendations in the 1983 Comprehensive Plan, the City authorized a complete replacement of the automatic control system. The complexity of the water system necessitated the use of a comprehensive and extensive control system to maximize efficiency and reliability. The cost of the proposed system necessitated the use of a phased approach for construction. This has the additional advantage of allowing the system operators to become proficient with new technology on a step-by-step basis. The phased plan is as follows: Phase 1 - Install digital automatic control equipment at all critical sites in the system. 3 - 25 CHAPTER THREE Phase 2 - Install digital automatic control equipment at all remaining sites in the system. Phase 3 - Install data logging equipment. Phase 4 - Install computer-based control equipment. Phase 5 - Provide advanced control algorithms for the computer control equipment. Phase 2 and Phase 3 have been completed. Phases 4 and 5 will commence when the City budget permits. * The construction of the new telemetry and supervisory control system has been successful. The system is both reliable and accurate, and enjoys a high degree of confidence by the system operators. Some improvements can be made, however, in the following issues: a. The control equipment is available from a single source. This source has shown poor response to requests for service and system upgrades. b. The City has the need to accumulate additional data in a more efficient format. c. The existing control,although reliable,is rudimentary. Additional,more sophisticated control algorithms are necessary to maximize efficiency and - reliability of the system. i 3 - 26 Chapter Four LAND USE AND ADJACENT SYSTEMS 1. STUDY AND SERVICE AREA The study area for this Comprehensive Water Plan Update is the area currently served by the Renton Water System and the additional area shown in the Skyway and East King County Coordinated Water System Plans. The water service area is shown on FIGURE 32 and includes the Maple and Green River Valley north of the City of Kent, portions of West Hill, Talbot Hill, Rolling Hills, and the Renton Highlands, and the Lakeridge-Bryn Mawr Water and Sewer District. Lakeridge-Bryn Mawr Water and Sewer District is served as a wholesale water customer,and operates a separate distribution system to deliver water to its customers. For this plan, this District is treated as a single demand on the water system and no attempt has been made to study the District system. The future service area of the water system has been established through agreements with all of the adjacent water systems, in conjunction with the East King County Coordinated Water System Plan and the Skyway Coordinated Water System Plan. In most areas, the existing service area and future service area coincide. Some boundary adjustments will be made, however, in the northeast and West Hill areas of the City, and both the existing and future boundaries are shown in FIGURE 3. For all planning purposes, the future service area boundary was used. The term "study area" used in this plan refers to those areas identified as the City's future service area through agreements with adjacent water systems and the members of the East King County Coordinated Water System Plan. The term "service area" used in this plan refers to the area served by the existing water system within the corporate City limits and established franchise areas. It should be noted that the study area included in the 1983 Comprehensive Plan was much larger than the study area in this plan. Several factors have occurred since the adoption of the 1983 Plan to reduce the expected saturation limits of the Renton Water System and service area. The most significant of these is the conclusion of the Skyway Coordinated Water System Plan and the East King County Coordinated Water System Plan, both of which identified ultimate service area boundaries for the utilities involved. Renton has agreed to the water system boundaries presented in each plan,although the existing boundaries will need to be adjusted to accomplish the revised boundaries. Location The City is located at the southern terminus of Lake Washington,which is southeast of the City of Seattle. The location has many unique characteristics such as: • Four hills located approximately at the periphery of the service area. • Three valleys within the service area, each of which has a river flowing through g it. 4 - 1 CHAPTER FOUR • Virtually all of the different types of geological deposits and stratas as a result of glacialrecession and advance, ranging from hard rock outcroppings on the West - Hill to very deep sand deposits below in the Cedar River near City Hall. • A natural location for major transportation corridors such as highways, railways, airports, etc., and regional utilities such as power transmission pipelines, natural gas pipelines, and others. The City of Renton represents a commercial nucleus as well as a corridor through which regional utilities pass. These factors have a significant impact on the existing Water System as well as planning for future conditions. Topography The topography of the study area presents variations,which include the extremes of a flat valley floor in the Green River Valley areas south of downtown to the gradual slopes going up to the Highlands and Talbot Hill areas, as well as the extreme of the steep cliffs along the Maple Valley. Elevations range from 20 feet to 540 feet above sea level (USGS datum). The effect of this topography upon the Water System has been discussed in Chapter 3 under the heading "Pressure Zones." Economy • Business and manufacturing, mining, and recreation all influence portions of the study area. The business and manufacturing community, located primarily in the valley floor, has a large transient population which commutes through the service area from the north and south. The business and manufacturing areas are large enough to influence water demand. Several industrial users have the capability to make large impacts on Renton's water demand patterns. Boeing Commercial Airplane Company and PACCAR are both currently served by the City of Seattle and Renton, although Renton has planned and constructed facilities to accommodate all supply to these users. In addition, several large tracts of undeveloped land in the Valley could be occupied in the future by large water users. The area has a mild climate, excellent transportation access, an airport, and many recreational opportunities including miles of lakefront and river access. All of these factors will contribute to the growth of the area. The area economy has experienced steady growth. Water use projections developed for this report assume that commercial and industrial water use will keep pace with population growth forecasts for the area. Restated,we have assumed that commercial and industrial growth will be proportional to population increases. 2. LAND USE Development in the service area is in accordance with the City's Comprehensive Land Use Plan and policies which represents a long-range plan for growth and physical development of the City. The current character of the City is reflective of the original Comprehensive Land Use Plan, which was adopted in 1965 and revised in 1968. Under this plan, industrial and commercial development was directed toward the Central and Green River Valley Areas to allow for further expansion of the City's business center. Residential growth under the plan was primarily ; • directed toward the eastern areas such as the Highlands and Talbot Hill areas of the City, since 4 - 2 Land Use and Adjacent Systems the West Hill was already developed primarily with residences. A summary of the land use that resulted from this plan is presented in FIGURE 4. Review and updating,of the Comprehensive Land Use Plan was initiated in 1975 to effect changes made in the economic,legislative,and land use philosophy of the City since the adoption of the original plan. To accomplish this updating, the original plan was divided into four planning areas: The Northeast Planning Area, the Southeast Planning Area, the Central Planning Area, and the Green River Valley Planning Area. Existing and proposed land use for each area was examined, revisions were proposed and hearings were held, with final revisions incorporated into the Revised Comprehensive Land Use Plan. Since 1975, all four Planning Areas have been examined and revised, and Land Use Plans adopted for each Planning Area. Planned land use in the service area is based on current City policy. Section 3A of the adopted policies element of the 1968 Land Use Plan recommends maximizing the use of available utility and service resources in existing areas prior to allowing developmentof outlying areas. This policy section provides the framework for current land use development and is stated below. SECTION 3A of the 1968 LAND USE PLAN LAND DEVELOPMENT OBJECTIVE: Growth and development should occur in a timely and logical progression of the existing urban area to maximize the use of existing services. POLICIES: 1. To minimize the necessity for redevelopment,premature development should only be allowed where it can be shown to be compatible with future use in the vicinity. 2. Development beyond the urban fringe should only be allowed where it is a consistent extension of urban services. 3. Vacant land surrounded by developed land should be given priority for development. 4. Land where adequate public utilities are available should be given priority for development. 5. A balance of residential,commercial, and industrial areas should be encouraged. 6. The upgrading and/or redevelopment of marginal areas should be encouraged. 7. The City should identify its sphere of influence. 8. Annexations should have logical boundaries. 9. To reduce processing time and effort and provide for efficient use of existing public facilities, large annexations should be encouraged. 10. Annexations that are economically advantageous should be encouraged. 11. Development requirements should be definite and reasonable. Based on these policy statements, the objectives of the Comprehensive Land Use Plan updates are as follows: 4 - 3 CHAPTER FOUR 1. To manage growth and physical development in the City and surrounding unincorporated areas. 2. To encourage growth in existing areas where the patterns of development are already largely set. 3. To direct expansion of residential,commercial,and industrial developments into areas where land,utilities, access, and community facilities are available with the capacity to accommodate the projected growth. 4. Allow higher dwelling densities in areas capable of supporting a higher level of development and lowering densities in areas where facilities are limited. The City is currently bounded in the south and west by Kent and Tukwila, and to the north by Lake Washington. The Water Utility has adopted service area boundaries to the north,east, and southeast, in conjunction with the East King County Coordinated Water System Plan. As a result,there is limited potential for expansion of the existing water system service area without annexation. Future land use is primarily a function of the location of existing vacant land within the City and the rezoning of existing designations. Water demand in the service area is dependent on the population of water users within the service area. The Renton Comprehensive Plan identifies twelve separate land use categories. For water supply planning purposes,only four categories are necessary. Although two different land use designations may have different community impacts,they also could have similar water use patterns. We have used the following designations: Land Use Category Water Planning Category Single Family Residential Single Family Low Density Multi-Family Residential Multi-Family Medium Density Multi-Family Residential High Density Multi-Family Residential Public/Quasi Public Extractive Industrial Commercial Light Industrial Heavy Industrial Parks and Recreation Public Right-of-Way Greenbelt Saturation land use populations were determined by calculating the areas of each designated land use category. This was accomplished by assigning land use designations to all parcels within a land use boundary on the computer base maps used for producing the figures for this plan. The area was calculated by the computer, using allowances for right-of-way and undeveloped areas because of terrain. 4 - 4 Land Use and Adjacent Systems Existing land use populations were determined by identifying neighborhoods and marking the developed areas on the computer base map. A summary of saturation area development is shown in TABLE 4-1. Unusable acres include areas too steep to develop or areas that are occupied by rivers or wetlands.

ADJACENT SYSTEMS The Renton Water System is surrounded by ten Public Water Systems as shown in FIGURE 3. The following is a brief description of each adjacent water system. Water District No. 107 Water District 107 borders the City in the northeast area adjacent to the Kennydale 320, Highlands 435, and Highlands 565 pressure zones. This District's comprehensive plan was prepared in 1980 by Yoshida, Inc. A 5-million-gallon reservoir was recently constructed near Hazelwood Elementary School, which is east of 116th Avenue and an eastward extension of Southeast 72nd Street. The overflow elevation is 440 feet above sea level, which is close to Renton's 435 overflow elevation in the Highlands reservoirs. An intertie between the two systems could be used to supply the 435 zone and the 320 zone during an emergency. Recent service area discussions with the District have resulted in the re-alignment of some of the future service area boundaries in the May Creek area. The May Creek area has steep topography, and the historical boundaries were not well suited for efficient water service. The future boundaries are shown in FIGURE 3. Water District 107 is supplied by the City of Seattle through the East Side Supply Line (ESSL). Water District 90 The comprehensive plan for this District was prepared in 1984 by Williams and Roth. District No. 90 serves areas east of the Highlands Elevated Tank, north of Maple Valley and south of District No. 107. District No. 90's primary pressure zone east of the City's Highlands elevated — tank pressure zone is served by a 645 pressure zone and also a lower pressure zone near Maple Valley. Neither of these zones is directly compatible with the City's Highlands Elevated Tank pressure zone. There is an abandoned intertie between Water District 90 and Renton, which was located at Southeast 128th Street at Union Avenue(132nd Avenue Southeast). The intertie was abandoned because of incompatibilities between pressure zones in the two systems. This area is experiencing high growth, and it is reasonable to establish negotiations for emergency water service between the two systems. Because of the rapid growth and the need to provide sewer service to this area,it is reasonable to expect some adjustments in the future service area in this section of the City, because Renton has a policy of not providing sewer service without annexation. Cedar River Water and Sewer District The Cedar River Water and Sewer District updated its Comprehensive Water System Plan in August, 1982. The Plan was developed by Mr.Richard C.T. Li,the District's Engineer, who had met with representatives .of the City to discuss system compatibility. The area under consideration for compatibility between the two systems lies within the District's west area, which includes the Maplewood Golf Course and areas east in the Maple Valley. Currently, the District does not provide service in this area at lower elevations in the Valley. However, its Comprehensive Plan does show service to this area by pressure reducing from the upper pressure 4 - 6 • Land Use and Adjacent Systems zones or by a connection to the existing Seattle East Side Supply Line along Maple Valley Highway. Soos Creek Water and Sewer District The Comprehensive Plan for Soos Creek Water District was developed in 1989 by Williams,Roth, and Associates. The District is located south and east of the City's Rolling Hills/Tiffany Park and Talbot Hill service areas. The District currently has an adjacent 598 pressure zone which borders the City's 590 pressure zone in the Rolling Hills area. The District has planned pressure zones at the 440 and 290 level to serve the areas east of the City limits in the Talbot Hill area, although no facilities in these pressure zones have yet been constructed. The City and District have been communicating regarding the transfer of service from the District to the City for the area known as Ponderosa Estates. There are also other areas between these two systems where negotiation of reasonable service limits for each entity should be developed. As an example, it is in the City's interests to serve the areas east of Talbot Road (96th Avenue South)up to the 250 foot elevation,approximately where the property line nearest this elevation occurs. This would establish a service area boundary based on hydraulic and topography considerations. Because the area in the Soos Creek area is largely undeveloped,it is suggested that Soos Creek Water District consider development of future pressure zones in the area adjacent to the City at the same hydraulic elevation as the City's pressure zones, namely 490 instead of 440, and 350 instead of 290. This would provide the opportunity for development of joint use facilities, which would allow each system to take advantage of economies of scale and minimize redundancy at the service area limits. The District is supplied by the City of Seattle from the Cedar River Supply Pipelines. City of Kent The most recent City of Kent Comprehensive Water System Plan is dated October 19, 1979, and was prepared by URS Company. A subsequent Water System Plan Amendment,prepared by the City of Kent, Department of Public Works, was completed in June, 1982. The 1979 Plan identified a shortage of supply in comparison with existing and projected demands within the Kent service area. Numerous recommendations were made in the 1979 Plan, including the recommendation to construct an intertie with the City of Renton. This intertie required pumping from the Renton 196 pressure zone into the Kent 240 pressure zone, and pressure reduction when flow was directed from Kent to Renton. This intertie has been constructed and, to date, Kent has used this pump station during peak use days of the summer for each of the past three years in order to meet its maximum day demands. Currently, a contract exists between the cities of Kent and Renton for Kent to be able to purchase supplies from the City of Renton so long as a surplus exists in the City of Renton. This contract has a clause-which allows the supply to be interrupted by the City of Renton at any time. The 1982 Plan Amendment presented a significantly reduced maximum day demand of 22 million gallons per day (mgd) rather than the 30 mgd presented in the 1979 Plan. A re- evaluation of the sources of supply resulted in the conclusion that groundwater sources or contractual service (from Renton, as an example) were not readily available. The conclusion 4 - 7 CHAPTER FOUR presented in the 1982 Amendment was that the City would have to develop surface water storage in an impoundment. This impoundment would have the capacity of approximately 2,265 acre feet and, in addition to other planned source of supply developments, would have a supply equivalent approaching 29 million gallons per day by the year 2000. It is emphasized that none of this supply capacity is predicated upon use of the Renton/Kent intertie pump station as a supply. In discussions with City of Kent's staff, they indicated that they are not intending to continue to use surplus Renton supply capability based on development of the sources of supply and storage identified in the Plan Amendment. The service area limits in the Green River Valley between Renton and Kent are southeast of 43rd Street(South 180th), west of the East Valley Freeway. The 1979 Comprehensive Plan and the 1982 Plan Amendment show the Kent service area east of the East Valley Freeway at Southeast 200th Street, which is the extension of the City of Renton's Springbrook Springs source of supply. Wasmeta Park Water System Currently, no comprehensive water system plan is available for the Wasmeta Park Water System. This system is operated as a private water user's association and serves an area immediately east of the City limits in the Maple Valley area, south of the existing Golf Course and north of the Cedar River. This system is supplied by two wells located within the development which pump from the Cedar River aquifer underlying the Wasmeta Park Development. It is highly probable that this area could request service from the City should their existing wells fail due to water quality problems,mechanical failures,or any other reason. The City has stubbed a 12-inch transmission line at the City limits which is adjacent to Wasmeta Park, and the pipeline has the capability to meet the system's requirements. City of Tukwila Tukwila's comprehensive plan was developed by Horton Dennis and Associates and was approved in 1985. Tukwila is served by the City of Seattle from the Bow Lake Transmission Pipelines (CRPL #4) and the Cedar River Pipe Lines. They are currently involved in the construction of numerous water system improvements,including a water storage reservoir and pump station in the North Hill area,and a Supervisory Control System. These improvements are physically and hydraulically remote from Renton's Water System. Tukwila operates its valley floor zone at 360 hydraulic elevation, which is significantly higher than Renton's 196 zone. An intertie could therefore be used to provide substantial emergency fire flows. Two interties have been constructed, one at Southwest 37th and the West Valley Highway, and the second at the Longacres Race Track, which is actually supplied directly by Seattle. Because of the large differential in pressure, these interties can produce as much as 5,000 gallons per minute (gpm). Tukwila has recently adopted policies that require Renton to pay Tukwila's demand metering charge if it is incurred while using an intertie. Recent negotiations with Tukwila have resulted in some service area transfers and an agreement for the alignment of future service area boundaries. These are shown in FIGURE 3. 4 - 8 Land Use and Adjacent Systems City of Seattle The City of Seattle serves a number of customers directly from the Cedar River and Bow Lake transmission pipelines. Examples of these include direct service customers in the West Hill, Earlington, and Black River area, as well as individual companies such as Boeing. The City of Renton's staff is currently negotiating with the City of Seattle's staff for transfer of some of these services as part of the Skyway Coordinated Water System Plan. Lakeridge Bryn-Mawr Water District The Lakeridge Bryn-Mawr Water and Sewer District (formerly Water Districts 63 and 14) is supplied in part by Renton on a wholesale rate basis through a single metered connection in the West Hill area. The West Hill reservoir and pump station are joint use facilities constructed under a cooperative agreement between the two systems. Lakeridge Bryn-Mawr also maintains an emergency connection with the City of Seattle in the event of a failure of the Renton transmission main. A copy of the joint use agreement is included in Appendix D. Skyway Water and Sewer District The Skyway Water and Sewer District represents a combination of former Water District Nos. 69, 77, and 88. They were combined in 1982 and are supplied by the City of Seattle from the Cedar River Transmission Pipelines. Water Supply in this area is governed by the Skyway Coordinated Water System Plan prepared in 1989 by Horton Dennis and Associates. 4. EAST KING COUNTY COORDINATED WATER SYSTEM PLAN (EKCCWSP) The East King County Coordinated Water System Plan (EKCCWSP) is the result of a study performed by Economic and Engineering Services (EES) under direction of the King County Council and the East King County Regional Water Association (EKCRWA). The EKCRWA is a group of water purveyors providing service within the Critical Water Supply Service Area (CWSSA)that was designated by the King County Council on December 15, 1985. The purpose of the study and plan is to develop recommendations for supplying water to the study area. Most of the water systems in the study area are supplied by the City of Seattle. Seattle has indicated they do not have sufficient capacity to supply purveyors'demands past the year 1994. The purveyors must therefore.decide whether to allow Seattle to develop the supply facilities necessary,or whether they should,as a group,construct their own regional supply facilities. The EKCCWSP examined these alternatives and concluded that the EKCRWA should develop independent, coordinated water supply facilities separate from the City of Seattle. Further, the plan suggests that the purveyors purchase the existing regional supply facilities from Seattle, and operate them with the proposed facilities. The plan is currently in the review and approval phase, a process which is expected to be completed in 1990. The plan includes several recommendations for constructing water supply 4 - 9 CHAPTER FOUR system improvements, and for the administration of the utilities in the CWSSA. The plan does not present detailed cost estimates of the cost of the proposed facilities and policies, and does not present a procedure for distributing the costs to the participants. It must be remembered that the primary purpose of the plan is to coordinate water supply for those utilities either served by the City of Seattle or experiencingsupply inadequacies. Renton is in a unique position in regard to the development and implementation of this program in that: 1. Renton's water service area has been included in the CWSSA boundary. 2. Renton has its own source of water supply, and does not rely on Seattle or regional transmission facilities for primary supply. 3. Renton is a member of the EKCRWA. Because of these unique characteristics, Renton may or may not decide to participate in implementation of the plan, if the plan is approved by the County and State. The decision on whether or not to participate should be based upon the benefits provided to the City by a regional supply system and the cost of those benefits. The EKCCWSP recommends the following improvements: • Prior to 1997 - Develop well field located near Issaquah as a regional source of water. • Prior to 1997-Construct a filtration plant for the South Fork of the Tolt River to develop additional supply from existing reservoir. • Prior to 2010 - Develop North Fork Tolt system with water filtration. • Prior to 2030 - In cooperation with Puget Sound area utilities, local governments, tribes, and others further study the development of the North Fork Snoqualmie, Skagit, and Cedar Rivers projects to identify the preferred method of meeting the Puget Sound area's municipal and industrial water supply needs. • Support the Seattle Water Department(SWD) in negotiations and plan to fully develop the Cedar River Watershed as a major component of the Puget Sound Regional Supply System. Planning activities for the Cedar River should include a joint federal/state/local study of the Lake Washington drainage basin to evaluate options for improved efficiency for water use at the Chittenden Locks,regulation of the outflow of Lake Sammamish, and other potential basin water management projects. • Support projects that will maximize the use of surface and groundwater development in a conjunctive mode and utilize interbasin transfer to make full utilization of existing systems. • Formally request Ecology to withdraw waters of the North Fork Snoqualmie and the Skagit Rivers from additional appropriations to 5.0 cubic feet per second(cfs)/3.2 mgd or , more in accordance with RCW 90.54.050(2)until July 1, 1994,or until the State reserves 4 - 10 • Land Use and Adjacent Systems municipal water supply, in accordance with RCW 54.54.050(1), for the future municipal needs of the Puget Sound area, whichever occurs first. • Assist the water utilities in immediately evaluating the potential for development of the aquifer located near Issaquah as a regional supply source. • Assist the water utilities in further evaluating the potential developable yields of the aquifers located in the rural area for use as subregional supplies. • Continue to work in cooperation with SKCRWA to maintain a Data Management Center for primary benefit to water utilities. • Support the inclusion of Phase III of Tolt Pipeline No.2 in the SWD capital improvement program for completion by June, 1992. The cost basis for distributing these costs to the individual water utilities has not been identified. It is our understanding that the cost basis will not be developed until after the plan is adopted by the County and the State. None of the projects identified results in increased water supplies to the Renton service area. The emphasis has been to augment supply to those utilities that currently experience supply problems, particularly in the East Lake Sammamish and Issaquah areas. It can be said, however,that increasing supplies to the utilities surrounding Renton has some favorable impacts on supply rate planning for the City. It should also be noted that the plan implies that all of the supplies available within the CWSSA(which includes Renton) will be used for the public good. It is possible, therefore, that supplies developed by the City, within the City, will be used in areas outside the City if those areas are deficient in water supply. We cannot make a recommendation regarding City participation in the Regional Supply Activities proposed by the Plan until the City's costs have been identified. We are, however, suggesting the following criteria be used after the costs are known: 1. The cost basis for allocating participation responsibilities should be based on direct benefit to the City. If the improvements provide no primary supply capability to Renton,the cost to participate should be zero. Renton rate payers should not subsidize other water utilities. 2. Renton must maintain control of the distribution of supply sources developed within the City,to the extent that they are needed to meet Renton's own water demands. Excess capacity may be used by the EKCRWA, but Renton must maintain control of the policies that determine the excess amount. 3. Renton must not compromise quality or reliability standards, even if a reduction in"regional"standards is necessary because of a shortage of regional supply. Renton should maintain a posture of cooperation for meeting the area's long-term water supply needs. However,the Renton rate payers have invested heavily in self-contained 4 - 11 CHAPTER FOUR reliable water supplies that should not be compromised for meeting regional water supply requirements. We recommend that the City maintain a representative on the regional planning committee. 5. SKYWAY COORDINATED WATER SYSTEM PLAN A coordinated water system plan was completed in November 1988 for the Skyway area using approximately the same procedures used for the East King County Coordinated Water System Plan. Renton serves only a small part of the area included in the planning boundaries, and therefore the impacts of implementing the Skyway plan are minimal to Renton. They include: li • Revised service area boundaries. These have been adopted by Renton as the boundaries of the future service area and are shown in FIGURE 3. These adjusted boundaries were used for all planning purposes. • The merger of Water District 14 and Water District 63 into the Lakeridge Bryn-Mawr Water and Sewer District. As a result,Renton now supplies the area occupied by former Water District 14 from the West Hill joint use facilities. This has resulted in the West Hill reservoir being marginally undersized, a condition which can be eliminated with a back-up supply to the West Hill area. • Construction of an emergency intertie with former Water District 14. J In addition,the planners for the Skyway plan have recommended that the Black River reservoir be constructed as a joint use facility at a higher elevation(above the 196 zone)to provide storage for the undeveloped Black River Quarry area. The purpose of this arrangement is to reduce loading on the West Hill reservoir, which may be undersized because of increased demands as a result of supplying Water District 14. Although this alternative should be examined in detail during the pre-design phase of reservoir construction, the West Hill reservoir deficiency can be eliminated by constructing additional supply to the West Hill reservoir. This will allow the Black River Reservoir to be constructed in the 196 zone, where it will operate most efficiently. 6. GROWTH MANAGEMENT ACT The Growth Management Act (GMA) of 1990 and 1991 (RCW 36.70A) establishes extensive requirements for the Water Department to plan under the requirements of the Act. Specifically, the Act requires that the Water Department perform the following: • Coordinate with the City Planning Department to identify Urban Growth Areas. Water service must be provided to the Urban Growth Areas in a quantity and quality to meet the zoning designation of the area. • Provide water supply to the Urban Growth Areas without decreasing the current level of service. 4 - 12 • Land Use and Adjacent Systems • Identify and protect aquifer recharge areas. • Develop a Water Capital Improvement Plan that is consistent with the City's overall Capital Improvement Plan. • Monitor building permit requests, and identify if there is sufficient water supply available to meet the needs of the proposed project without reducing the current level of service. • Coordinate with the City Planning Department to identify potential utility corridors. • Involve the Public in the implementation and adoption of this Comprehensive Water System Plan. • Impose impact fees on new developments to cover the cost of providing fire flows. To date, the Utility has complied with all the GMA requirements except those detailing the adoption of the Water Comprehensive Plan. The public participation requirements will be followed during the plan review phase. Renton has been a leader in the adoption of policies and ordinances to protect its aquifers, and has coordinated closely with the Planning department on the interaction of this plan with the City Comprehensive Plan. Renton will continue to actively participate in regional planning coordination, and will comply with all requirements of the GMA. The GMA compliance requirements are part of an on-going process of City-wide coordination. The Water Department will budget for and participate in future GMA coordination requirements. 4 - 13 Chapter Five DEMANDS 1. WATER USE CLASSIFICATION The City of Renton's waterusers are divided into five customer classifications: 1. Single-Family Residential 2. Multi-family 3. Commercial 4. Public 5. Wholesale Single-family residential customers and multi-family customers are the largest water using group in the City, and will account for approximately 69% of all water use at saturation. Water delivered to these customers is used for domestic purposes and irrigation. The irrigation component during the summer months increases, and is responsible for a majority of the equalizing storage volume necessary in the reservoirs. Each single-family residential meter is equal to one equivalent residential unit (ERU). For saturation planning purposes, each undeveloped acre is assumed to equal 6 ERUs. Multi-family customers consist of low-and high-density apartment and condominium complexes. These customers typically use(per unit)approximately 60%of the water used by a single-family residence, primarily because of reduced irrigation requirements. Each multi-family apartment or condo unit is equal to 0.6 ERUs. For saturation planning, each undeveloped acre is assumed to equal 13 ERUs. Commercial customers consist of retail and wholesale businesses,light and heavy manufacturing and warehouse operations, schools and businesses. The water demand from these customers is more uniform throughout the year, and does not exhibit significant demand peaks during the summer. These users were identified as one ERU, unless their metersize was larger than 1". The larger metered customers were individually evaluated, and their specific water use habits were assigned an appropriate number of ERUs, corresponding to an equal number of single- family residences that would have been required to produce the same demand. For saturation planning, each undeveloped acre was assigned 5.3 ERUs. Public customers include parks and recreation areas and were assigned a demand equivalent of one ERU per acre. This value was identified by evaluating the irrigation requirements of Cedar River and Liberty Park during the summer of 1987. For saturation planning, greenbelt areas were also assigned demands of 1 ERU/acre. i A summary of equivalent development by Planning area is shown in TABLE 5-1. , 'j 5 - 1 CHAPTER FIVE TABLE 5-1 EQUIVALENT DEVELOPMENT BY PLANNING AREA ERU 1987 SATUR- SATUR- PER AREA 1987 ATION ATION ZONE ACRE (acres) ERU's ACRES* ERU's , DOWNTOWN 196 ZONE Single-family 6 266 1,596 275 1,650 Multi-family 13 226 2,938 684 8,892 Commercial 5.3 1,579 8,369 1,947 10,319 Public 1 684 684 799 799 SUBTOTAL 2,755 13,587 3,705 21,660 HIGHLANDS 435/KENNYDALE 320 1 Single-family 6 424 2,544 630 3,780 Multi-family 13 35 455 300 3,900 , Commercial 5.3 26 138 225 1,352 Public 1 221 221 336 336 SUBTOTAL 706 3,358 1,521 9,368 !

This District is composed entirely of single-family residences and is considered to be at saturation development. Demand in this District is included in the West Hill operating area. 2. WATER USE HISTORY For demand development and planning purposes,the water system is divided into five operating areas. The areas are shown in FIGURE 1 and listed below: 1. Downtown 196 pressure zone 2. Highlands 435/Kennydale 320 pressure zone (435/320) 3. Highlands 565 pressure zone 4. Rolling Hills 590, 490, Talbot Hill 350, 300 and Scenic Hill pressure zones (490/350) 5. West Hill 495 and 270 pressure zones (West Hill) For planning purposes, each operating area functions as an independent water use area with its own unique supply and storage facilities. Each operating area has a unique customer class distribution and, therefore, exhibits demand patterns that are not the same as the aggregate demand for the entire service area. Each operating area was examined independently. Accurate water use data was used for planning purposes, since supply and reservoir levels in each operating area are accurately measured and recorded. Reservoir level records were differentiated on an hourly basis to synthesize flow rate values both into and out of each reservoir. These flow rates were appropriately added to or subtracted from the supply flowrates in each operating area to develop true water demand on an hourly basis. In order to develop maximum day demands and demand peaking factors, the five highest water use days in 1987 were used. These days were chosen by evaluating supply pumping records for each summer day of 1985, 1986, 1987 and 1988. The days of June 28,June 29,July 13,August 3, and August 4 of 1987 were the highest use days of this period. Demand was greater in 1987 than in 1988 because of Seattle's water conservation program. Well flow rate charts, booster station flow rate charts, and reservoir level charts were then obtained. The data was reduced to flow rate into and out of each operating area on an hourly basis. Peaking factors and diurnal demand curves were developed on an operating area basis,not a system-wide basis. TABLE 5-2 shows a summary of system demand for the past five year period. 5 - 3 .

POPULATION ESTIMATES AND DEMANDS The basis for water demand in the City's service area is the population of single-family homes, multi-family homes, businesses, industries, schools, and parks within the service area. The necessary capacity of the water system facilities is determined by the water demand that will be encountered from those uses. Facility sizes are, therefore, dependent on the number and distribution of homes,businesses, industries, schools, and parks. Maximum demand will occur when saturation development is served, and saturation development is dependent on land use policy adopted by the City Council. Saturation demand is determined in this report by evaluating the maximum historical demands which occurred in 1987,normalizing these demands with respect to the existing population, and expressing them in terms of demand per equivalent residential unit(ERU). This factor is then applied to the projected population to arrive at a projected demand. An EQUIVALENT RESIDENTIAL UNIT (ERU) is defined as a service connection which consumes the same amount of water as the average single-family residence within the service area. A single-family residence by definition equals 1 ERU. Multi-family dwellings equal 0.6 ERUs per unit. Large and industrial users are converted to ERUs by individually examining water use history. The number of ERUs attributed to large or non-residential demand within the service area is calculated by the ratio of actual or assumed demand to the demand per ERU. Future population and demand projections are based on the same criteria just described, using saturation population and land use densities within the service area shown in FIGURE 3. The population within the service area was evaluated in quarter-quarter(sixteenth) sections to determine the distribution of demand when saturation development within the service area occurs. In comparison, existing development was evaluated. The existing population and land development was determined by using meter records, field counts, and maps to identify the current number and type of water services. The current land use policies were then applied to the undeveloped land to project the saturation levels of development. It should be noted that the existing land use plan does not extend past the year 1995. We have used this as a basis for saturation planning, however, since an alternative and more accurate basis is not available. It is anticipated that this plan will be updated several times before saturation development occurs, and subsequent studies can use more accurate information, when available. After the existing and saturation population projections were developed, a detailed demand analysis was performed. An evaluation of historical demand in the Rolling Hills and Talbot Hill area was used and extrapolated on a City-wide basis for determining typical water use habits. Historical demand was then expressed in demand per ERU and used to predict future demand. The demand per ERU calculated is actually the water supplied to the service area by the supply sources. Actual customer demand is less than supply due to unaccounted-for water, such as leakage and hydrant flushing. This is acceptable since it introduces some conservatism into the demand estimates. Using this procedure, demand per ERU on an average water use day is 300 gallons per ERU per day, and demand per ERU on the peak day in 1987 is 800 gallons per ERU per day. Winter demand is used to maximize turnover in the reservoirs. Maximum day demand is used for 5 - 5 CHAPTER FIVE determining the required capacity of the booster pump stations and the reservoirs in the service area. Future demand is calculated by combining historical demand per ERU in 1987 with population projections. Future demand is calculated at saturation development, although no attempt has been made to identify the year in which saturation development occurs. For planning purposes, it is sufficient to interpolate between present and saturation demand and use the percent growth in the demands to identify necessary facilities and improvements. Using this approach, system facilities are sized by determining the system demand and using TABLE 5-3 to identify recommended facility sizes. For budgeting purposes, it is important to estimate a growth rate so that Capital Improvement planning can be coordinated with utility revenues. TABLE 5-3 is an estimate of system growth using a combination of Gomportz and logistic curve and,observed growth data for the Renton area. The growth rate matches favorably with the annual growth rate of 1.8%identified in the King County Annual Growth Report for the Renton area. The maximum growth rate shown reflects the results of a weak leak-reduction program, no conservation, and hot weather. Theminimum growth rate shown reflects an aggressive leak- reduction program, maximum anticipated conservation impacts, and normal summer weather patterns. - 5 - 6 MGD P !Ji o v, o !-^ o ,VI o !." o 8 8 8 8 8 8 8 8 8 8 8 .. . .... ... .. ... . . . . 1990 -: v - -=� - �� 1 111 1 1111 1,11 1111 1111 ... :;.;{ �ii:;ii:•i$�:$•i:;i;it;:.;i:;�:;:: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 .1.1II1.0 11,1:1.11.111.1111111 111 III I 1111 1111 1111 N N N N N N N N t.)

FACTORS AFFECTING DEMAND Two items have the biggest impact on water system demands: population and weather. Population growth has a tendency to increase the average daily demand on any particular day, whereas high temperatures have a tendency to increase the peak hour demand above the average rate for the day. Water conservation efforts will also impact demands and can be used in some circumstances to accommodate system growth without increasing the City's supply capacity. These issues and impacts are addressed in the City's Water Conservation Plan. 5. DEMAND COMPONENTS Total System demand can be divided into three major components which consist of: • Residential Demands (Single-Family and Multiple-Family Services) • Commercial-Industrial, Public Facilities and Other Use Demands • System Losses (unaccounted-for water) These three components(growth,weather,conservation)are comprised of both peaking and non- peaking demand elements. Peaking demands are those demands that vary with time(seasonally, weekly, daily, or hourly), such as irrigation demands. Peaking demands are the major contributors to the difference between average annual and maximum day demand, and they are also the most difficult and costly to meet. Non-peaking demands are those demands which do not vary seasonally, such as normal household(inside the house) or commercial demands. Residential demand is a major component of the City's total System demand. This can be concluded from the large areas of predominantly residential neighborhoods served by the System and from actual demand records. In 1987,the ratio between maximum to average day demands was 2.56:1. A conclusion reached here is that a major portion of this difference between maximum day demand and average daily demand represents the water used for irrigation and other hot weather-related uses. Commercial and industrial demand also represents a major component of the total System demand. Major industrial users such as the Boeing Company and Pacific Car and Foundry (PACCAR) use significant volumes of water, although their variations in daily demands are minimal. Commercial and other industrial users such as retail stores, businesses, and manufacturing parks typically have steady flow,non-peaking demands,which are fairly constant in aggregate. The remaining demand component, System loss or unaccountable water, is predominantly leakage. Comparison of the 1987 supply data with demand data from actual customer billing records indicates that a significant percent of the water supplied to the System was unaccountable. Older areas of the System generally exhibit greater perservice demands due to increased losses from broken pipes, bad joints, and other exfiltration loss. Losses between 10- 15%of total System supply are generally considered acceptable for a System the size of the City of Renton. The percentage of unaccountable water during 1987 varied from a high of 33% for the period of January through June, 1987, to a low of 12% during the peak two month period of July and August, 1987. Explanations for the wide variation in these values can be attributed 5 - 21 CHAPTER FIVE to either actual System losses (leaks, under registration of meters, etc.)or pump station meter errors. It is recommended that inoperable or suspect meters be replaced or repaired as soon as possible in order to determine accurate water supply values, and that the City continue to evaluate unaccounted for water so that reductions may be made where necessary. In simulating the City System, 800 gallons per service connection per day were used for maximum day demand, plus fireflow conditions. With better metering of the System facilities and leak detection program for the distribution system and service connections, changes may result in water consumption which could influence future demand projections. Therefore,future System demand should be closely monitored to identify change which could alter the design criteria of this Report. 6. FIRE CONDITIONS The capability and reliability of a water system is critical during fireflow periods. During these periods, an adequate combination of supply, storage, and system pipeline capacity must be available to meet the fire fighting requirements. To determine the behavioral characteristics of the City's Water System during a fire, a comprehensive evaluation of the fireflow capability of every fourth hydrant in the City's Water System was performed and a map showing the results of the evaluation is available at City Hall. The Insurance Services Office (ISO) guideline, "Guide for Determination of Required Fireflow," is used to estimate the fireflow demands of buildings located within the City's service area. Averages were developed for multi-family residences, commercial buildings, and industrial complexes within the City for specific fireflow requirements based on experience in the past five years. For this report, fireflows were established by the Fire Marshall and were used for establishing the City's Water System performance criteria. For specific buildings or complexes, the City's Fire Marshall should be consulted to determine actual fireflow requirements. Under the ISO criteria, the primary goal of a water system is to provide water to a fire at a sufficient rate and duration to extinguish -the fire. Adequate storage and supply is useless if the transmission or distribution system cannot deliver water at the required rate necessary to extinguish the fire. To achieve this goal, the ISO recommends that the following standards be met in conjunction with the recommended fireflow demand: 1. It is assumed fireflow demand will be required during a period of maximum day demand. 2. A major component of the water system will be out of service either due to repairs or maintenance. This can either be a major transmission pipeline, storage reservoir, or source of supply for the water system. 3. Maximum transmission main velocities are 8 feet per second (fps). Computer simulations for the comprehensive fireflow capability evaluation were based on ISO criteria, with either the largest source of supply, a reservoir, or a booster pump station out of service or a maximum pipe velocity of 8 fps. Information on a specific fireflow capability for a specific area or a summary of this evaluation can be obtained from the City Fire Marshal's Office or the Public Works Department. 5 - 22 Demands 7. CERTIFICATES OF WATER AVAILABILITY In accordance with the requirements of the Growth Management Act (GMA), the City must identify that water is available prior to approving each building permit. A"Certificate of Water Availability" is issued if there is sufficient water supply to meet maximum day demand conditions and provide supply to the applicant at the same level of service as the remaining customers. In 1987, the City supplied the equivalent of 25,425 equivalent residential units (20.34 mgd). The City has the capability to supply 23.2 mgd with all of its on-line and standby supply sources operating and a failure of Well 8, the largestsupply source. The water system, therefore, has the capability to provide water supply to 29,000 equivalent residential units. The City can therefore add approximately 3,575 equivalent residential units. • 5 - 23 Chapter Six WATER RESOURCES 1. EXISTING SUPPLY Renton is currently using water pumped from six wells and one artesian spring for supply to the water service area. The wells and spring operate as the primary water supply sources. In addition,the City maintains supply interties with the City of Seattle in the Rolling Hills and the West Hill areas as emergency sources if the City's wells are out of service. The Seattle supplies are used for emergencies only. As a third level of supply, Renton has interties with the City's of Kent and Tukwila. It should be noted that most of the water systems adjacent to the Renton Service area are supplied by the City of Seattle on a wholesale-rate basis. Renton is unique in that they have pursued and accomplished development of a City-owned, independent water supply. The Puget Sound Council of Governments has identified water supply as one of the most important regional issues in the Puget Sound area. Recent events have indicated that water is a limited commodity, and the potential for civic development exceeds the capability to supply clean water. Renton's water supply needs alone will increase two times before saturation development is reached using existing zoning. Renton's response to the following key issues may dictate the City's capability to supply a growing population in the years to come: 1. The City must protect the quality of its existing water wells from adverse development impacts in the well recharge area. 2. The capability to obtain water rights and additional supply capacity may be restricted or prohibited. 3. The City of Seattle may not have excess supply capacity to supply water to Renton through interties. 4. The formulation of a regional supply organization may improve or may hinder supply to the Renton service area. 5. Raw water treatment may be required. Water resource policy,and the development of additional supply sources should be the Water Utility's highest municipal priority. These issues will be discussed in this Chapter. 2. AQUIFER PROTECTION The City of Renton relies primarily on groundwater as a supply source for the water system. Ninety-five percent of the City's water supply is pumped from a shallow aquifer in the Cedar River Valley near Liberty and Cedar River parks (downtown aquifer). Development of supply in the downtown aquifer has been successful in that it has provided substantial volumes of very high quality water. It is assumed that the potential for increased withdrawal rates is possible and that the aquifer is, in fact, the City's best source of long-term water supply. 6 - 1 CHAPTER SIX The aquifer is shallow and is covered by permeable material; therefore, several potential contamination problems exist from industry, commercial, and retail development in the aquifer recharge area and from the transportation of contaminants through the aquifer area. j Groundwater contamination would directly and immediately affect all Renton water customers. The Renton City Council has ranked aquifer protection as its number one priority, and it is the single most important issue in providing a reliable water supply to the service area. Aquifer protection can be classified into four areas: 1. Forced reduction or elimination of uses or users of possible contaminants within the aquifer area which have a moderate to high potential for contaminating the groundwater. 2. Physical protection of the groundwater area from surface contaminations (if they exist). 3. Early detection and remedial removal of groundwater contaminants to prevent them from reaching potable water withdrawal points. 4. Public awareness program. The City has adopted policies in all four areas to provide a maximum reasonable level of water quality security. In January of 1984, a study was authorized to investigate alternatives for protecting the aquifer area. In August of the same year, a second study was authorized specifically dealing with the well field area. The results of these studies were adopted by the - City Council in Resolution No.2553,which contained specific recommendations for limiting uses in the aquifer area and for proceeding with additional analytical work. During 1986 and 1987, a groundwater movement study was performed to identify recharge areas and the extent of ground water protection boundaries. This study involved the construction of several monitoring wells. As a result, the Maplewood Golf Course was acquired for use as an alternative well field. In November of 1986, the City applied for sole source aquifer protection from the Federal Government. During the summer of 1987, a high-stress aquifer pumping test was conducted as the first step in developing a groundwater computer model and determining the amount of aquifer recharge from the Cedar River. In the spring of 1988, following a tetrachloroethylene (PCE)contamination and a gasoline station leak,the City adopted an underground storage tank ordinance, Resolution No. 4147. The resolution requires that all tanks in Zone 1 of the aquifer protection area be either removed or provided with secondary containment within a five-year period. In April of 1988, the Council adopted Resolution No. 2715, which adopted the Aquifer Protection Area and set the limits of the recharge area for groundwater supplies. The sole source aquifer designation was received on June 8, 1988. In November, Resolution No. 4186 was passed,which identified zoning requirements for hazardous waste and storage within the aquifer protection area. In the spring of 1989, the City applied for grant funding from the Centennial - Clean Water Fund for sampling and analytical equipment and development of a well head protection program. The results of this funding request are still pending. Due to the extensive amount of analytical work performed and as a result of the development of the groundwater computer model, a great deal is known about the characteristics of the Downtown aquifer. The aquifer is recharged primarily within the area outlined in FIGURE 3. Some recharge is present from the Cedar River,although current data suggests that this amount is less than five percent of the City's well withdrawal rate. Flow rates and flow directions within 6 - 2 Water Resources the aquifer,however,are not yet completely understood,although it is assumed that additional testing and modelling can provide an accurate contaminant transport model. Protective Legislation Groundwater protection must be pursued through the legislative process. The regulations directed at protecting groundwater and the guidelines for responding to groundwater contaminations are established through Federal, State and City legislation. There are several Federal Statutes which effect groundwater contamination. The United States Environmental Protection Agency has primary responsibility, although some other Federal agencies are indirectly involved. In response to the increasing concern regarding the contamination of groundwater, the EPA has established the office of Groundwater Protection within the office of Water Resource Technology. Current Federal Statutes provide substantial protection for groundwater. TABLE 6-1 provides a brief description of the Federal Statutes and the agencies which are associated with groundwater protection.

The Washington Department of Ecology(Ecology)has the primary responsibility for coordinating groundwater protection efforts and overseeing the development of groundwater management plans. Ecology has prepared a groundwater quality management strategy to provide a comprehensive approach to protecting groundwater resources. The State defines the strategy "to maintain high quality for all waters of the State allowing no reduction of water quality except in overriding considerations of public interest". No reduction in quality would be allowed to adversely affect the ability to use water for its intended beneficial use. Similar to EPA groundwater protection strategy, Ecology attempts to bring together numerous statutes which protect groundwater and develop a comprehensive framework for groundwater protection. The strategy outlines several recommendations for improving groundwater protection. The strategies include: . 1) developing and adopting state-wide standards for groundwater quality,2)establishing a means of treatment for potentially polluting activities, 3) establishing rigorous waste discharge requirements, 4) increasing emphasis on groundwater protection hydrology and aquifer hydrology, 5) developing a comprehensive data management and monitoring program, and 6) providing technical training affect groundwater and public education. TABLE 6-2 is a brief description of the most significant State statutes. TABLE 6-2 SUMMARY OF STATE LEGISLATION PERTAINING TO GROUNDWATER Regulatory Agency RCW Title Response WSDOE 18.104 Water Well Regulates the construction of water wells and establishes Construction Act licensing for drilling contractors.

WSDOE 90:48 Water Pollution Maintains highest possible standards for all waters. Control Act Issues waste discharge and disposal permits. Renton has adopted ordinances directed at protecting the Downtown aquifer. The primary means of controlling use within the aquifer recharge area is through the comprehensive land use planning process and land zoning. The groundwater can be protected through implementation of zoning designations,which restrict or prohibit uses that can cause groundwater contamination. In order to apply this approach, existing zoning designations need to be evaluated and their effect on groundwater contamination assessed. Many of the zoning activities are addressed in a pending ordinance regarding development and use within the aquifer protection area. If a change in the existing zoning is considered, the effects of the new zoning on existing activities must be examined to determine if violations will occur. - 6 4 Water Resources Contamination Sources It is important to recognize that groundwater contamination can occur from several sources, many of which already exist within the aquifer area. They include septic systems,underground petroleum storage tanks, sanitary sewer leachate, and contamination of the river and surface sources. The aquifer protection ordinance deals with specific methods for wastewater treatment and disposal, stormwater management, open space requirements, septic system permits and underground storage facility permits. The following is a description of potential causes and possible prevention methods for the existing sources of groundwater contamination within the City. Septic systems pose a high threat to groundwater contamination. This contamination source is difficult to control because it is made up of a large number of small sources. Because of the possibility of volatile organic compounds in household waste, the leachate from septic systems may cause contamination to occur. Groundwater contamination from septic systems can be prevented with varying success by implementing one or more prevention programs,including 1) prohibiting the discharge of hazardous chemicals into the septic system, 2) implementing an aquifer area-wide review and replacement of damaged or failing septic systems,and 3)restricting new septic system construction. State and County standards for septic systems are intended to protect both human health and groundwater; however, in some areas this may not be enough. Construction of new septic systems should be restricted unless it can be shown that the area does not have a high risk of groundwater contamination. In addition, all residents should be required to connect to sanitary sewers if a line is nearby. Leakage of petroleum products from underground storage tanks can be a major source of groundwater contamination. The most significant threat within the aquifer area comes from automobile service stations and other facilities which store either gasoline and diesel fuel in buried tanks. A small scale threat,but more widespread,is the numerous tanks used for storing heating oil for individual home owners. Petroleum products contain aromatic hydrocarbons and lead which can be hazardous to humans if consumed. Contamination of groundwater from underground petroleum storage tanks can be prevented through several techniques: 1) incorporating monitoring devices around underground storage tanks, 2) using state-of-the-art engineering materials and installation techniques, 3) pressure-testing of petroleum pipes and storage tanks,and 4)removal of leaking storage tanks. Monitoring for petroleum products will not protect the groundwater from contamination but will provide early detection of leakage. This will help initiate the necessary mitigating measures to avoid contamination of the groundwater. A secondary containment structure or double-walled storage tank is considered to provide the best protection against groundwater contamination. Leakage of petroleum products from the primary containment tank can be detected through monitoring systems while still contained within the secondary containment structure. These issues are addressed in detail in the City's underground storage tank removal ordinance. Surface source contaminants which originate from the land are primarily associated with surface water contamination;however, these same contaminants can migrate within an aquifer recharge area to the groundwater. Several contaminant sources are common fertilizers, pesticides and herbicides, motor fuel and oil, and heavy metals. Fertilizers, pesticides and herbicides are used for both residential and agricultural applications within the aquifer recharge area. These chemicals provide a variety of both organic and inorganic compounds, and contamination can occur through both application and improper storage. The reaction of 6 - 5 CHAPTER SIX different chemical compounds with the soil varies considerably. Phosphorous and potassium,the primary constituents of fertilizers, are readily absorbed by soil particles. However, nitrate compounds, also found in fertilizers, migrate through the soil quite easily. The organic compounds used in manufacturing the various pesticides and herbicides varies considerably. As can be expected, the absorption, volatilization, biodegradation and solubility of each of these organic compounds also varies. The U.S.Environmental Protection Agency and U.S.Department of Agriculture regulate the testing, manufacturing, marketing and use of most fertilizers, pesticides and herbicides; therefore, proper use of these chemicals is not believed to be a major source of groundwater contamination. The greatest threat will come from the improper storage of large quantities of these chemicals. Most of the roads within the aquifer recharge area are equipped with storm drainage systems. These storm drains provide concentrated aquifer recharge points if they leak. Precipitation run-off from the road to the storm pipelines contains roadway contaminants such as motor fuel and oil. The hydrocarbon contaminants can then migrate along with the precipitation run-off down to the groundwater through leaking pipes. A monitoring program to identify leaking storm sewer pipes and corrective action will reduce groundwater contamination from these sources. Heavy metals such as barium, cadmium,lead and mercury originate from a variety of sources and can find their way to the groundwater. Barium salts are used in the manufacturing of paints and paper, cadmium is used in the manufacturing of batteries, paint and plastics, and lead is found in lead-based paint and leaded gasoline. Mercury can be found in batteries, insecticides and fungicides. Informing customers and users of the proper disposal of these household products is the most effective way to prevent this type of groundwater contamination. Groundwater Monitoring If a contamination occurs, the water supply can be protected by restricting the transport of the contaminant through the zone to the water table or by containing the spread of the contaminants and removing the contaminant within the contained area. Because of the diversity of groundwater contaminants, no one method of prevention can be applied to all situations. Each situation must be examined independently to determine the best method for the prevention of groundwater contamination. Monitoring is an essential activity for a groundwater protection program. A monitoring program can provide information for planning and decision making,evaluate the effectiveness of pollution control programs, and indicate areas of groundwater contamination. Knowing the benefits of groundwater monitoring, the United States Environmental Protection Agency Office of Groundwater Protection has developed groundwater monitoring strategies. The objective of this strategy is to provide a framework for systematically addressing the most critical needs, which include monitoring, data collection, data analysis, and response. The data collection objective of the monitoring program includes three phases. The first phase is ambient monitoring, which will help define background information, baseline groundwater quality,the current status of the groundwater resource and groundwater hydrology. Most of this information has already been developed by CH2M Hill in the groundwater protection monitoring study. The second phase is point of contamination monitoring, which is designed to indicate potential groundwater problems at locations where hazardous products are used or stored. Monitoring of this type should be designed such that the hazardous contaminant is discovered -, 6 - 6 '_i Water Resources before it comes in contact with the groundwater source. This would allow cleanup of the contaminant without groundwater contamination. Much of this work is included in the proposed aquifer protection ordinance. The third phase is point of use monitoring, which includes sampling the water after it is pumped from the aquifer to indicate if groundwater contamination exists. Since many sources of contamination are from non-point sources, it is impossible to monitor all potential groundwater contamination sources. Therefore, point of use monitoring is necessary to protect the water consumer. The City currently samples all of its wells for analysis by independent laboratories. However,the interval between sample analysis and sample results is too long to provide sufficient safety or to establish baseline chemical levels. The data analysis objective is used for two purposes. First, it is used to establish a baseline for existing contamination levels. If contamination levels exceed the baseline levels, then they may indicate a contamination potential and appropriate action can be taken. Second is the use of monitoring data to compare a contamination concentration with drinking water standards. If a specific contaminant concentration exceeds the maximum concentration level set in the standards,then it can be assumed that the public health is at risk and appropriate action taken. The objective of a response plan is to prevent a contaminant from reaching the water user. If a groundwater contamination occurs or the threat of contamination is present, specific steps must be taken to minimize customer impacts. The process for selecting an appropriate response to a groundwater problem involves four steps: 1) preliminary assessment and data gathering, 2)development of response alternatives, 3) analysis of response alternatives, and 4) selection of an appropriate response. The initial response to a contamination is an assessment of the situation and the collection of available data to determine the nature and the extent of the problem. The assessment is based on available information; however, if the information is insufficient, a conservative estimate must be made. If the contamination has created a hazard to public health, all necessary action must be taken to protect the water supply. Determining the best response to a contamination threat involves developing a list of response alternatives. The response alternatives may include source control or point of use remedial actions. Once a comprehensive list of response alternatives has been compiled,each alternative must be analyzed in order to select the most appropriate response. The analysis begins with an initial screening, which is used to eliminate inappropriate alternatives, followed by a detailed analysis of the remaining alternatives. The selection of the appropriate alternative is performed such that it minimizes the threat to short-term and long-term public health effects. The City has adopted a policy of aggressive action to protect its aquifer,and this approach should continue. The following chronological list identifies the efforts in the 1980 decade to protect the City's aquifer: ACTION DATE • Standard DOH required quality information available Prior to 1980 • Comp Plan Recommends Aquifer Protection Program April 1983 • Tanker overturns on I-405 August 1983 • Aquifer Protection Study Authorized January 25, 1984 • Well Field Protection Study Prepared by CH2M Hill August 1984 • Amendment to Well Field Protection Study Adopted May 1985 (In above Prepared by CH2M Hill document) • Aquifer Protection Study Adopted Resolution No. 2553 July 23, 1985 6 7 li CHAPTER SIX • Groundwater Monitoring Movement Study - Data August 8, 1985 gathered 1986-1987 • Golf Course Acquired for Aquifer Protection and Emergency 1985 • Olympic Pipeline Spill in Maple Valley 1986 • Sole Source Aquifer Protection Application November 24, 1986 • PACCAR Monitoring Wells/Contamination January 1987 • Wells 1-2-3 Relocated/Redeveloped Spring 1987 • Aquifer Test June 24-26, 1987 • Data Report for the City of Renton Cedar River Valley June 1987 Aquifer Test - RH2 Engineering/Hydrogroup, Inc. • Analysis Report for the City of Renton June 1987 • Cedar River Valley Aquifer Test RH2 Engineering/Hydrogroup, Inc.

WATER RIGHTS The State Water Code,as outlined under Title 90 of the Revised Code of Washington,states that all surface and ground waters of the State are the property of the public. Furthermore,it is the policy of the State to promote the use of the public waters in a fashion which provides for obtaining 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 instream and natural values and rights (90.03.005 RCW). The right to use public water for a beneficial use must be acquired through the appropriation of water rights through Ecology. Appropriation of such rights is provided in that first in time shall be first in right, subject to the rights of the riparian property owner. When application to obtain water rights is submitted to Ecology, the date of receipt of this application establishes the priority of the water right. Prior to the development of a source of supply,a temporary permit is issued by Ecology to construct,develop,and test the supply source. A water right may then be issued following a thorough review process and a determination of the amount of supply which is put to beneficial use. This water right establishes priority use of the water, and becomes an appurtenance to the property. A summary of the existing water rights for the City of Renton's municipal water supply is presented in TABLE 6-3. The City is currently utilizing its full water right for its production wells RW1,RW2,and RW3,and PW8 and PW9. Production well PW3 currently has an operating capacity of 1,600 GPM. PW3 is currently maintained only as an emergency source of supply. The City's Well Nos. 4 and 5 have active water rights but are not currently operational. 6 - 9 CHAPTER SIX - t TABLE 6-3 SUMMARY OF WATER RIGHTS FOR THE CITY OF RENTON WATER SUPPLY SOURCES Ecology Amount of Current Capacity of Source of Supply Water Right Status File No. Water Right (gpm) Source (gpm) Springbrook Springs Certificate 463 1,032 600 Certificate G1-02605 1,050 Well No. 1 Certificate 886-D 1,040 Certificate 5838-A 960 Well No. 2 Certificate 887-D 1,040 Certificate 5836-A 1,960 Well No. 3 Certificate 5835-A 1,600 1,600 Replacement Well No. 1 Temporary Permit 2,200 Replacement Well No. 2 Temporary Permit 2,200 Replacement Well No. 3 Temporary Permit 2,200 Well No. 4 Certificate 844-D 170 Well No. 5 Certificate 3591-A 1,300 Certificate 5834-A 200 Replacement Well No. 5 Temporary Permit 1,250 Well No. 8 Certificate 6775-A 3,000 3,500 Certificate 6776-A 500 Well No. 9 Certificate G1-24191 1,300 1,300 Well No. 10* Temporary Permit G1-24783 1,600 1,600 I Well No. 11 Temporary Permit G1-24781 1,600 2,500 i Application G1-25396 1,400 Well No. 12* .

Production Well PW-9 was drilled and developed and was granted a water right for 1300 GPM; 2. The water rights of the City's production wells PW1, PW2, and PW3 are in the process of being transferred to the replacement wells RW1, RW2, and RW3. 6 - 10 Water Resources Production wells PW1 and PW2 have been abandoned. However, production well PW3 still remains operational. The City has submitted applications for water rights in the Maplewood area of the Cedar River Valley for Well nos. 10, 11, 12, 14, 15, and 16. These applications were submitted in order to establish the City's priority under the "first in time, first in right" premise. At this time, action has been taken regarding several of these applications. In a letter dated March 14, 1988, Ecology granted temporary permits to drill, develop and test water production wells 10, 11, and 12. After Well No. 10 was unsuccessfully drilled (in its present location), Ecology granted a temporary permit to drill, develop, and test Production Well 17. At this time, the drilling, developing and testing of wells 11 and 17 have been completed, and the City is proceeding with perfecting the water rights for these two wells. It is possible under some situations to reserve water rights for the future. The Water Resource Act of 1971 set forth the procedures relating to the reservation of water for future public water supply. This regulation is covered under Chapter 173-590 WAC, which establishes and sets forth a procedure whereby any person within the State of Washington may petition Ecology to reserve water for future public water supply. The City is working closely with Ecology regarding its present and future water resource needs. Continuation of this relationship is essential to ensure future supply sources for the Renton water system. Several items may impact Ecology's ability to grant water rights or process water right reservations. First, it must be shown that new water wells do not impact stream flows in the Cedar River. The river valley is restricted to groundwater development under the guidelines and procedures identified in the Instream Resources Protection Program. The City has successfully shown that hydraulic continuity between the Cedar River Aquifer and the Cedar River is less than the maximum allowable standard set in the program for several of its wells currently under development. This was accomplished by developing a detailed computer model of the aquifer flow and recharge characteristics. The computer modelling program should continue, to allow future wells to be located in areas that do not impact the surface water flows in the river. Second is the potential passage of legislation which will reauire all water users to coordinate on a regional basis for water supply resources. If this legislation passes, the East King County Water Utility Coordinating Committee (EKC WUCC) could be the organizing body. This association is still in the formulation stage and has not developed specific policies or recommendations for regional water supply. Renton should continue to participate in regional organizations to ensure that Renton's water needs are preserved. Of particular concern is the preservation of Renton's high standards for water quality and reliability. Water Budget The City is preparing to develop a water budget for the Cedar River Basin in order to better manage all of its water resources and to evaluate the impacts that Well Nos. 10 and 12 and the Golf Course Irrigation Wells have on the Cedar River instream flow. The water budget will document the quantity of water entering the basin, including precipitation, snow melt, transfer of water from other basins via either the surface or subsurface, etc.; and the quantity of water leaving the basin,including per capita consumption,irrigation, fisheries enhancement, releases to Puget Sound, and transfers out of the basin via either direct release or subsurface flow. 6 - 11 CHAPTER SIX Consequently,the water budget will determine what flows are available to meet permitted water uses in various parts of the Cedar River Basin during different times of the year, thus creating a real-time management system. The water budget will supplement the lower Cedar River Basin Plan as well as the Cedar River Action Plan, which are intended to document surface water quantity and quality, respectively. The proposed water budget will be accomplished in a series of phases, which will provide increasing levels of accuracy, identification of levels of inaccuracy, and the significance of that inaccuracy on the overall water budget for the Cedar River Basin. 4. CHELAN AGREEMENT The Chelan Agreement is the result of bringing competing interest groups to the same table. In 1990, representatives from local government, tribes, state agencies, business, environmental, fisheries, recreation, and agriculture hammered out an agreement on how to cooperatively plan water resources on a regional level. As part of the agreement,the Water Resources Forum was created. It consists of representatives from the same eight interest groups. The Forum recommended the selection of two pilot projects to Ecology. The pilot projects will test how well the Chelan Agreement's regional planning process works. They are in the Methow Valley on the east side of the mountains and in the Dungeness/Quilcene area on the Olympic Peninsula. The Forum and Ecology will be watching how well the planning process works. After the two plans are developed,they will be implemented through local ordinances and Ecology regulations. Ecology and the Forum will then assess whether the planning process and its subsequent ordinances and regulations can be applied to other regions. The Chelan Agreement does not tell Ecology how to allocate water rights. Instead, it recommends a planning process in which all interest groups within a region have their say. Three groups can initiate the process: local governments, federally-recognized Indian tribes, or state agencies. Those three groups, along with representatives from the five remaining caucuses (and any other interest groups granted caucus status within the region),must reach a consensus about the plan. The plan will go through a SEPA process, including active public involvement and comment, prior to Ecology review. Once approved by Ecology, the plan becomes the new basis for allocating water rights in that region. Ecology may postpone some decisions about future water needs while the Chelan planning process evolves. In fact, many major water suppliers are deferring major basin plans until the regional planning process is in place. Ecology does,however,recognize that some decisions about pressing water needs must be made. If approval of a water right would create significant conflict among the seven interest groups, then a separate conflict resolution process could be initiated by either local governments, tribes, or a stat agency. It is called a Critical Situations Process and is spelled out in the Chelan Agreement, and has now been made an Ecology regulation. Ecology will expedite water rights applications when a local government demonstrates it needs the resources now, and no issues are raised by local governments, tribes, or state agencies. Before the water right is approved, however, the water system must prove that it is meeting conservation criteria, as mandated in the 1989 Water Conservation Act. Ecology believes, and 6 - 12 Water Resources local governments have concurred, that conservation in many areas will provide enough additional supply until the regional planning process works. It is too early to tell if the Chelan Agreement will be used as the vehicle for allocating all future water rights. It is clear that the procedures used in the past will be changed and new procedures adopted. One of the procedures that will be studied is the 'banking"of water rights. Ecology believes that in some areas, the available water has been over-allocated, and in some areas there are water rights that are not being used. Some regional water resource problems may be solved by retrieving the unused rights and distributing them to the over-allocated areas. Ecology is offering payment for the unused rights as an incentive to return them to the "water bank." Renton will actively pursue a cooperative role in the Chelan Agreement process,and will examine all of the water rights that have been allocated and are under City control. Unused and un-needed rights will be returned to the State for regional use. 5. WATER QUALITY The City's existing supply sources have been and are currently of high quality. Recent chemical analyses show that all supply sources are within the standards set by the U.S. Environmental Protection Agency(USEPA), the Department of Health(DOH), and the American Water Works Association (AWWA). All of the City's existing supply sources are currently using chlorination for disinfection. Bacteriological Characteristics TABLE 6-4 summarizes the bacteriological data for several of the most recent samples collected from the City's supply sources. The bacteriological data shows that several samples collected during March of 1988 through November 1988 exceeded the maximum contaminant levels(MCL) as set forth under the DOH rules and regulations. The source of bacteriological contamination was identified as a broken sanitary sewer main located upstream of the City's well field. The broken main was located and repaired. The most recent samples show that the bacteriological results are within the MCL standards.

Inorganic Chemicals and Physical Characteristics TABLE 6-5 summarizes the inorganic chemical and physical characteristics of the City's supply - } sources. At the present time, the USEPA has proposed maximum contaminant levels for eight inorganic chemicals. In addition, the maximum contamination levels have been set for copper, lead and fluoride. These proposed levels sometimes differ from those recognized by the DOH rules and regulations. However, a list of current and proposed inorganic chemicals is presented here. A noted addition under the physical characteristics is the measurement of asbestos fibers -and the measurement of Giardia Lamblia in the supply sources. Both of these physical characteristics are proposed National Primary Drinking Water Regulations.

Recent regulation changes, and the potential for stricter Federal quality standards, may require that __ Renton install additional water treatment equipment. This is particularly true with the new standards proposed for lead removal. The City should participate to the extent possible 6 - 16 Water Resources in the development of reasonable standards, and should respond promptly to treatment requirements. The operating staff currently samples production well water every 3 months for VOCs, or more frequently if quality complaints are.received. The samples are sent to local laboratories for analysis and typical turn-around time for sample results is 6 weeks or more. A comprehensive sampling program will require that sample results be obtained within a one or two day period, to protect the public health from undetected contaminations; therefore, the City should obtain their own water quality laboratory. The sampling locations are shown in FIGURE 1. Lead The presence of lead in drinking water is currently being reviewed by the Environmental Protection Agency, and preliminary indications are that all Municipalities will be required to meet zero tolerance lead standards (undetectable levels). Lead is introduced into the water system through lead joint pipe, lead solder fittings, and galvanized iron pipe. The City has a small amount of lead joint pipe which may need to be removed in the near future. Current city construction standards do not allow the use of galvanized pipe or lead solder in the distribution system; however, many homes are still constructed using these materials. It is unclear where the City's responsibility for removing lead contaminants will end. We recommend that the City pursue the following actions for lead related water quality problems: 1. Begin a program to remove all lead joint pipe and other distribution system items which are potential contributors of lead in the drinking water. 2. Maintain communications with State and Federal regulatory agencies regarding new and pending lead related legislation. Comply with all requirements. 3. Discourage the use of g galvanized pipe and lead solder fittings in residential and commercial plumbing systems. Corrosivity Renton's water is extremely corrosive, having a Langlier Index of-3.3 to -3.5. Corrosive water reduces the service life of plumbing, distribution system mains,pumps, treatment systems, and reservoirs. Several methods exist for controlling the corrosive properties of water, including raising the pH and adding sequestering chemicals to the supply sources to form a protective coating on the interior of pipes, pumps and reservoirs. Corrosion control measures should be examined to determine the most effective way to mitigate Renton's corrosive water. 6. Water Quality Laws The Safe Drinking Water Act (SDWA) was enacted in 1974 as a result of public concern about water quality. However,it did not address all of the public's concern about unregulated organic contaminants. Their concern,along with frequent contamination of groundwater from industrial solvents and pesticides, created the momentum to substantially revise the original act, which 6 . 17 CHAPTER SIX resulted in the SDWA amendments of 1986. Subsequently,many new regulations based on these amendments have been developed by the United States Environmental Protection Agency(EPA). Regulations which will be discussed here include the Surface Water Treatment Rule(SWTR),the Total Coliforms Rule, the Volatile Organic Chemicals (VOCs) and Unregulated Contaminants Rule, the Public Notification Rule, the Lead and Copper Rule, the Radionuclides Rule, and the Wellhead Protection Program. It should be noted that the State is responsible for adopting and implementing the SDWA amendments; hence, the finalized rules may be stricter. The Surface Water Treatment Rule (SWTR) The Surface Water Treatment Rule (SWTR), finalized on June 29, 1989 and made effective on December 30, 1990, covers all public water systems using surface water, which includes groundwater under the direct influence of surface water. Its purpose is to protect the public from waterborne diseases. It stipulates two general rules: First, all surface waters must be disinfected;and second,all surface waters must be filtered unless certain stringent water quality source requirements, disinfection, and site-specific conditions are met. Treatment is required because it is difficult to monitor for particular microorganisms. The State must review groundwater systems to ensure they are not under the influence of surface water. States have until June 29, 1994 to determine which groundwater systems are subject to the SWTR. If a system is designated not under the influence, then it only needs to comply with current State requirements. If a system is designated as under the influence and is unfiltered, then the system has six months to begin fulfilling the SWTR's monitoring and reporting requirements, and if Maximum Contaminant Level(MCL)violations occur, the utility has to install filtration within 18 months. The City will be exempt from the rule if they can prove that their groundwater source is not directly connected to surface water or, as worded in the rule, is not under the direct influence of surface water. The State will develop criteria for determining a direct influence. Groundwater systems likely to be under the influence include springs,infiltration galleries,Ranney wells,and wells less than 50 feet deep. The SWTR went into effect on August 1, 1991, but the State DOH requested an 18-month extension to promulgate its own rules. Basically, to avoid filtration, surface systems must: 1. Comply with turbidity MCLs 2. Comply with coliform MCLs 3. Meet the disinfection requirements for systems that do not filter 4. Maintain a watershed control program 5. Comply with trihalomethane (THAI) requirements For complete details on the regulatory requirements, please see the Surface Water Rule, A Working Explanation of the Surface Water Treatment Rule, published by the American Water Works Association. 6 - 18 Water Resources Total Coliforms Rule Coliforms are one group of microbiological contaminants regulated as part of the SDWA amendments. Total coliforms, which include the fecal coliforms, are usually not pathogenic. However, their presence in drinking water indicates the potential presence of pathogens associated with waterborne disease outbreaks. Presence of fecal coliforms in drinking water indicates the possibility of an urgent public health problem. The Total Coliform Rule may impact the City because it mandates two major changes in current procedures for total coliform testing: 1. The testing must be based on the presence or absence of total coliforms in a given sample, not on an estimate on the specific density of coliforms. 2. All samples testing positive for total coliforms must be followed by repeat sampling to further test whether fecal coliforms are present. The Total Coliform Rule requires considerably more monitoring than under the original law, especially by small systems. In addition, every public water system must develop a monitoring plan, with sampling locations, subject to approval by the State. Sanitary surveys are intended to serve as another line of defense against contamination by alerting water systems and state governments of possible health risks that may not be apparent from routine coliform sampling. The sanitary survey is conducted by the State or an agent of the State. The Total Coliform Rule calls for initial and subsequent sanitary surveys of systems serving 4,100 or fewer persons within a specified number of years. For community water systems,the survey must be completed by June 1994, and a subsequent survey completed in the next five years. The sanitary survey consists of three parts: planning,surveying, and reporting. The SWTR and the Total Coliform Rule are closely related. If the concentration of coliform exceeds the standards in the SWTR, mandatory source water disinfection would be required. If the coliform presence does not exceed the standard in the SWTR, available technologies, other than disinfection, can be used to correct the problem. Examples include: protection of wells by appropriate placement and construction; proper maintenance of the distribution system, including main-flushing programs; revised operation andmaintenance of storage tanks and reservoirs; and continual maintenance of positive water pressure in all parts of the distribution system. Public water systems must develop a monitoring plan and begin monitoring for total coliforms by August 1, 1991. AWWA has published a document entitled Total Coliforms: A Working Explanation of the Total Coliform Rule, which contains a detailed explanation of compliance and violation requirements for the Total Coliform Rule. VOCs and Unregulated Contaminants Rule Volatile (synthetic) organic chemicals (VOCs) are chemicals that evaporate or vaporize easily. Millions of pounds of VOCs are manufactured each year and used as solvents, degreasing compounds, and raw materials for production of other compounds. The VOC Rule,published on July 8,1987 and effective on January 9,1989,includes maximum contaminant levels(MCLs)and monitoring requirementsfor eight VOCs in drinking water. It also establishes monitoring requirements for 51 other unregulated contaminants. 6 - 19 CHAPTER SIX Trihalomethanes (THMs)were the first VOCs regulated by the EPA in 1979. At that time, the EPA was primarily concerned about VOCs in surface water. However,it became apparent that a considerable amount of groundwater is contaminated by organic compounds other than THMs, most of which are VOCs. The VOC monitoring standard requires taking one sample per quarter for each groundwater source. Composite samples of up to five sources are allowed. Implementation of the initial monitoring requirements are phased, based on the size of the population served, with small systems allowed to have the longest time period for implementing them. For example, public water systems with less than 3,300 people must begin monitoring on January 1, 1991 and finish by December 31, 1991. The sampling site and monitoring frequency depend on the source water type. Systems with groundwater sources must sample at points of entry into the system. Repeat monitoring has to take place every five years for systems where no VOCs were detected in the initial sample and the source was not designated as vulnerable. A system is considered vulnerable for a period of three years after any positive sample of one or more VOCs. At this time, the State is informing utilities when to monitor on an individual basis. Violations of VOC levels requires treatment. The utility has 90 days to comply once notified by the State to monitor for VOCs and unregulated contaminants. The VOCs and Unregulated Contaminants: A Working Explanation of the VOC in Unregulated Contaminants Rule, as published by the American Water Works Association, describes the best available technologies for treatment of VOCs, possible variances, and exemptions to the VOCs f rule, and lists the VOCs and unregulated contaminants. Public Notification Rule The American Water Works Association has published a document on public notification, A Working Explanation of the Public Notification Regulation Rule, which describes the procedures for notifying the public when the water system violates any of the standards for contaminants regulated. The revised public notification requirements took effect on April 1989; therefore, utilities should begin outlining a procedure for compliance with this rule. Lead and Copper Rule The EPA has developed a universal corrosion control program for medium- and large-size utilities. Systems with more than 50,000 customers must begin corrosion control treatment. The State will be required to develop acceptable treatment alternatives. The EPA will publish a corrosion control guidance manual to aid states and water utilities in implementing this rule. For both lead and copper, the EPA has defined "action levels." The action level for lead is greater than 0.015 mg/1 in more than 10% of high-risk homes (undefined). The action level for copper is greater than 1.3 mg/1. When these action levels are exceeded, the EPA requires the following steps to be undertaken: extensive additional sampling,treatment systems to minimize concentrations of lead and copper attributable to source water, and public education programs to reduce exposure. Water systems that continue to exceed lead action levels would be required to replace all lead source connections that contribute in excess of 0.015 mg/1 to tap water lead levels. 6 - 20 Water Resources The City will be required to begin monitoring in July of 1992 at approximately 40 sampling sites every 6 months. Radionuclides Rule The EPA is currently developing new regulations for monitoring of radium 226 and 228, uranium, and radon (radionuclides). Proposed MCLs are 300p CO for radon and 20p CO for uranium and radium 226 and 228. The final rule is due March 1992. Monitoring for radionuclides is to be scheduled on a nine-year compliance cycle divided into three-year compliance periods, with the first period beginning January 1, 1993. During each three-year compliance period, systems will monitor radionuclides at the time specified by the State or other primary agency. The number of samples will vary depending on how the distribution system is supplied;i.e.,by several groundwater and/or surface water sources. Water systems should analyze for the radionuclides covered by the rule and determine whether changes in treatment practices will be necessary, and if so, estimate the cost of treatment. An article describing the new radionuclide regulation was published in the AWWA Journal, April 1991. The Wellhead Protection Program The amendments to the SDWA require states to develop a Wellhead Protection Program and submit it to the EPA for review and approval by June 19, 1989. The underlying purpose of the program is to protect public water supply wells from sources of contamination. To date, only six of thirty states that have submitted their Wellhead Protection Programs have had their submittals approved by the EPA. Washington has not submitted a Wellhead Protection Program. SWDA's Impact on the City Since groundwater supplies City customers,Renton will primarily be concerned with compliance with the Total Coliform Rule, the Lead and Copper Rule, and Radionuclides Rule (radon removal). Exotic organic and inorganic contaminants,which require significantly more expensive treatment technologies, rarely occur in public water supplies at levels above proposed MCLs. The City has already developed an aquifer protection plan in an effort to avoid disinfection. A study is currently underway by EES To identify the specific impacts of the new water quality laws. The water quality study should continue as needed until all standards and requirements have been satisfied. It is widely accepted that all municipal water supply systems will eventually need to filter and treat all potable water supplied to the public. If this is true, Renton will eventually need to construct a water treatment plant near the existing Cedar River well field. The Utility Department should pursue the acquisition of a treatment plant site for future use. 6 . 21 Chapter Seven POLICIES AND DESIGN CRITERIA 1. INTRODUCTION The policies,design criteria and standards used in the water system are based on laws and policy which originate from six sources as follows: Federal Regulations 'Jr State Regulations 1 Renton City Council 1 Renton Mayor 1 Public Works Administration 1 Water Utility Staff The laws and policies adopted by these sources are used to operate the water system on a day-to- day basis and to plan for growth and improvements to the system. The objective is to provide high-quality water service at a minimum customer cost. 7 - 1 CHAPTER SEVEN I The highest three levels of establishing policies and laws - 1) Federal Regulations, 2) State Regulations, and 3) Renton City Council - dictate requirements that are set by law. An entity lower on the list may not adopt laws or policies that are less stringent or in conflict with laws or policies adopted by an agency higher on the list. Law is set by the Federal government through Federal regulations, by the State of Washington in the form of Statutes, and by City Council in the form of ordinances. The last three entities - 1) Mayor, 2)Public Works Administration, and 3)Water Utility Staff- dictate requirements that are set as policy. In general,lower entities do not conflict with policy set by a higher entity. The policies are set in the form of Memorandums and Job Descriptions, and are summarized in this Comprehensive Plan. The laws, policies and standards established are used to determine if the existing water system is deficient under various existing and future water demand conditions. The system's ability to meet these demands are detailed in Chapter 8, and recommended improvements are identified in Chapter 9. It is important to understand that if standards are set too low,customers will not be satisfied, and if standards are too high, the cost of installing and operating facilities to meet such standards is too high. All of the policies and standards have the general purpose of providing an acceptable level of service to the water rate payers. "Service" is therefore the single most important aspect of the construction, operation, maintenance and administration of the water system. The following categories combine to meet this service goal: 1. Supply 2. Customer Service 3. Finance 4. Facilities 5. Organization A policy outline is shown in TABLE 7-1. The policies associated with each category are identified in this Chapter. - 7 - 2 TABLE 7-1 WATER POLICY OUTLINE SERVICE V V V V V SUPPLY I I CUSTOMER I FINANCIAL FACILITIES I ORGANIZATIONAL I SERVICE CO POLICYSTATEMFNT POIJCYSTATEMFNF POLICY STATEMEVT POLICY STATEMENT POIJCYSTATEMEIYT Provide the highest quality Provide the customer with Provide water supply at a Maintain all facilities to Provide sufficient staff to water in sufficient quantity adequate or better service reasonable cost to all achieve maximum use achieve all other policy to meet the needs of the customers go 'r.1 City 0 r 2 Aquifer Praion Annexations Cost of Service Design Criteria Structure w tat inseam Resources Service Inside City Zero Based Financing Level of Maintenance Level of Staffing Quality Goals Regional Participation Inside City Rates Level of Reliability Responsibilities Regional Supply Service w/U Annexation Outside City Rates Vulnerability Criteria Other Department, Conservation Temporary Service LID's Joint Use b Water Rights Emegeey Service Latecomer's Czi Chelan Agreement Planning Boundaries Systee Development Charges ' 4 Treatment (r] Corrodon Control 7i O 4 V CHAPTER SEVEN 2. SUPPLY POLICIES Quality Protection (Source: City Policy) • Renton will pursue Aquifer Protection and other methods to meet or exceed all water quality laws and standards. • Renton will take all reasonable measures to protect its supply aquifers. • Aquifer Protection is the Water Utility's highest priority. • The quality goal of the Water Utility is to maintain water quality at a level that meets or exceeds the water quality in its natural state. • Renton will pursue and maintain an active role in protecting the regional environment. • The Water Utility will pursue maximum supply rates without impacting the regional environment. Quantity (Source: City Policy, State Law) • The Water Utility will meet or exceed all laws and regulations. • The Water Utility will observe water rights seniority. • Renton will pursue the acquisition of water rights to meet or exceed saturation development conditions. Conservation (Source: City Policy) • Renton will promote the efficient and responsible use of water and will conserve during a water shortage. Regional Participation (Source: City Policy) • Renton will participate on Regional Supply activities to reduce cost of service and improve reliability, quantity and water quality. • Renton will supply all customers within the City limits. 3. CUSTOMER SERVICE POLICIES Annexations (Source: City Policy, State Law) • Areas annexed without existing municipal supply will be served by Renton. • Areas annexed with existing municipal supply must meet Renton Water Standards. 7 - 4 POLICIES AND DESIGN CRITERIA • Renton will follow state guidelines in the assumption of facilities in annexation I areas. • Service to areas outside of the City limits without annexation will be evaluated on a case-by-case basis by the City Council. • Renton Water will not be mixed with water supplied by other systems. • Areas annexed with existing municipal supply will not be supplied with Renton water. Temporary Services (Source: City Policy) • Compliance with standards may be deferred for temporary water service. Emergency Service (Source: City Policy) • Compliance with standards may be deferred for emergency water service. • Policy criteria may be waived for emergency service. -' Planning Boundaries (Source: City Policy) • For planning purposes, the City will use water service boundaries established by 100 agreement as a result of the regional coordinated water system plans, and agreements with Kent. • Renton will follow state guidelines in assuming portions of adjacent water systems as a result of annexation. 4. FINANCIAL POLICIES • The utilities will use a rate setting process which complies with standards established by the American Water Works Association (AWWA) and the Environmental Protection Agency (EPA). • Rates and additional charges established for the Water Utility should be: Cost-based rates which recover current, historical, and future costs associated with Renton's water system and services. - Equitable charges to recover costs from utility customers commensurate with the benefits they receive. Adequate and stable source of funds to cover the current and future annual cash needs of the Water Utility; and - Easy for the customer to understand and easy for the customer to administer. • The existing customers of the Water Utility will pay the direct and indirect costs of operating and maintaining the facilities through user rates. In addition, the 7 - 5 CHAPTER SEVEN user rates will include debt service incurred to finance the capital assets of the Utility. • • New customers seeldng to connect to the water system will be required to pay a special utility connection fee for an equitable share of the historical cost of the system's capital improvement plan. Connection fee revenue will be used to finance the Capital Improvement Program. • New and existing customers will be charged for extra services through a separate ancillary charge based on the cost to provide the service. Ancillary charges can increase equitability and increase operating efficiency by discouraging unnecessary demand for services by the customers. Revenue from ancillary charges will be used to finance annual operations and maintenance. • The utilities will maintain information systems which provide sufficient financial and statistical information to ensure conformance with rate-setting policies and objectives. • There are two widely-used, generally-accepted methods for determining the total revenue requirements of a water utility-the cash basis and the utility basis. The water rates will be developed using the cash basis, which is a method commonly used by publicly owned utilities. • The user charges must be sufficient g to provide cash for the expenses of operating 11111 and maintaining the utility. To ensure the fiscal and physical integrity of the utility, an amount should be set aside each year for capital expenditures from retained earnings. That is, an amount should be set aside to cover some portion of the depreciation of the physical plant. The amount may be transferred from the Water Fund to the Construction Fund for general purposes or for specific purposes such as to create a reserve for main replacement. • A Working Capital Reserve will be maintained to cover unanticipated emergencies, bad debts, and fluctuations in cash flow. The cash reserve will be equal to $500,000 for both the Operating and the Construction Fund based on the amount used by the Finance Department. • Customers should be classified as single-family, multi-family, commercial, industrial, governmental, senior citizen, hydrant, and fire protection. These are the existing customer classes for the utility. • The criteria used to project demand and size facilities will be based on the "worst case" comparison of: 1) historical or 2) comprehensive planning statistics. This will result in conservative financial planning. • The growth rate and the inflation rate will be based on rates used by the Finance Department. • The large industrial users will be charged for services on the same basis as all other users. - - 7 - 6 • POLICIES AND DESIGN CRITERIA • For customers residing outside the City limits, water rates are 1.5 times the residential City rates. • The utility will use generally accepted cost allocation principles for all cost allocation purposes. • The water rates will be based on either the Base-extra capacity method or the Commodity-demand method. Both methods strive to equitably charge customers with different service requirements based on the cost of providing the water service. Service requirements relate to the total volume of water used,peak rates of use, and other factors. • The water utility provides fire protection services in addition to water services. A separate cost allocation for fire protection services should be established. • The utility's fees and charges should be calculated for the service area as a whole. Rates will be the same regardless of service location (except for the inside city/outside city distinction discussed earlier). •. The utility will charge customers for extra service through a separate ancillary charge based on the cost to provide the service. The charges should be reviewed regularly and updated annually based on increases in the Consumer Price Index for the Renton area. 11110 • Following are the additional charges currently adopted for the utility. Fee ($) Year Adopted Water Meter Installation (3/4") 400 1982 Water Meter Installation (1" and up) Cost + 15% 1982 • Turn off/on 20 1987 Delinquent Charge 10 1974 Violation Charge 20 1982 Meter Testing(for 3/4" increase with size) 5 1974 • The term "connection fees" refers to the one-time fee paid by a property owner when connecting to the water system. The utility will charge,for the actual cost of services and equipment required to make a new connection(hookup fee or meter charge) and will charge a reasonable fee so that new customers will bear an equitable share of the historical cost of the system. • According to Ordinance #4205, the owner of properties which have not been assessed or charged or borne an equitable share of the cost of the water 7 - 7 CHAPTER SEVEN distribution and water plant facilities shall pay prior to connection to a water Ilp main one or more of four special connection charges: • 1. Latecomer Fees. Per Ordinance#4189,latecomers'agreements are granted to developers, owners, and the City for the reimbursement of a pro rata portion of the original costs of water systems. 2. Special Assessment Charge. The special assessment is a charge for the historical costs for the water distribution system, which shall include the water distribution mains that lie adjacent to or near properties that would benefit directly therefrom that were not installed by LIDs or by a private developer under a Latecomers Agreement. The charge will be based on: A. The number of units of property frontage to be serviced by the water system determined in the manner prescribed in RCWs for determining "assessable units of frontage" multiplied by the actual local improvement assessment per unit of frontage for such facility in Renton for the year in which the main was completed. B. In addition,there shall be a charge of 10%per annum added to such cost but not larger than 150% of the original assessment cost. 3. Special Utility Connection Charge. The Special Utility Connection Charge shall be assessed against any property that has not participated in the � development of the water system, induding the wells, pump stations, �, reservoirs, and transmission mains. The charge shall be: A. $300 per single family residence and mobile home; B. $175 per living unit of an apartment,condominium,motel or similar multi-family occupancy residential structure; C. 4¢ per square foot of property connected for all other properties. 4. Inspection and Approval Fees. Inspection and approval fees will be charged flat rate of 2% of the cost of construction. 5. FACILITY POLICIES This section details the planning criteria to be used to establish an optimum behavior level and a standard of quality for the Water system. Pressure (Source: City Policy) • A minimum of 30 pounds per square inch (psi) at customer meters shall be provided during normal demand conditions, not including a fire or emergency. 7 - 8 POLICIES AND DESIGN CRITERIA 111) • A maximum of 130 psi at system meters shall be provided during normal demand conditions, not including pressure surges. Pressure over 80 psi will be reduced with individual PRVs. • Maximum allowable pressure suppression during normal demands is 30 psi. • During fire conditions, the minimum pressure at any major risk and in the remainder of the system is 20 psi in the water main (also ISO criteria). • 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. Velocities (Source: City Policy) • Under normal conditions, the velocity of water in a transmission main should be less than 4 feet per second (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. Source of Supply • It is the City's policy to pursue the elimination of all supply from the Seattle Cedar River Transmission Pipelines and to supply all customers within the Water System's service area from the City's supply sources. However,the Seattle supply meters will remain operational to provide emergency supply if it is necessary. • The City is actively pursuing saturation planning for supply sources so that future water resource limitations can be handled effectively and the impacts of limitations can be minimized. • The capacity of the source of supply, wells,springs,booster stations,and transmission mains, shall be sufficient to meet maximum day demand(including industrial demand) and to replenish storage used during a fire within 72 hours after a fire. The supply system should be capable of meeting this criteria with the largest supply source out of service, or any other combination of failure that is considered reasonably possible which has an effect on supply sizing, locating or , planning. Storage (Source: Washington State Department of Health [DOH], City Policy, Engineering Practice) • Storage within the Distribution System must be of sufficient capacity to supplement transmission supply when peaking demands are greater than the maximum day demand rate (equalizing storage) and still maintain sufficient storage for a fire or other emergency condition. • Equalizing storage must be stored above the elevation which yields a 30 psi service pressure to the highest service in the zone. 7 - 9 CHAPTER SEVEN • Fireflow storage must be stored above the elevation which yields a 20 psi service pressure to the highest service in the zone. • The emergency storage criteria available from the ISO were considered in the study. The quantity of emergency storage provided will approach these requirements as closely as possible,considering economic factors and other design criteria. • Sufficient emergency storage must be provided so that should a fire occur, the supply capacity from the reservoirs would be sufficient to fight the fire while meeting the average rate of the maximum day demand. • Sufficient storage for a fire condition is the product of the fire protection water demand and the required duration. • Location of storage facilities should be in areas where they will satisfy the following requirements: 1. Minimize fluctuations in system pressure during normal demands. 2. Maximize use of the storage facilities during fires and peak demands. 3. Improve the reliability of the supply for the Water System. Transmission and Distribution (Source: American Water Works Association [AWWA], City Policy) • Where practical, transmission and distribution mains shall be looped to increase reliability and decrease head losses. • All mains shall comply with the generally recognized design criteria from the AWWA as follows: 1. In residential areas,the grid of distribution mains should consist of mains at least 6" in diameter arranged so that the lengths on the long sides of block between intersecting mains do not exceed 600'. Where longer lengths of pipe are necessary, 8" or larger mains are required. Where the layout of the streets and the topography are not well adapted to the above arrangements, or where dead ends and poor looping are unavoidable, 8" should be the minimum main size. 2. In high-value districts, the minimum size should be 8", with intersecting mains in each street; 12" or larger mains should be used on the principal streets and for all lines that are not connected to other mains at intervals close enough for proper mutual support. • All new construction shall be in accordance with the Renton Standards for additions to the Water System. 7 - 10 POLICIES AND DESIGN CRITERIA ‘10 • Distribution System design assumes that only adequately-sized service line will be used. All residential service lines will be 3/4"or larger copper,according to City ordinance. Service lines will be the same size as the meter. • Valve installations shall satisfy the following criteria: 1. Zone valves shall be located at all pressure zone interfaces to allow future pressure zone re-alignment without the need for additional pipe construction. 2. Isolation valves shall be located wherever necessary to allow individual pipelines to be shut down for repair or installing services. A minimum of three valves shall be provided per cross, and two valves per tee. 3. Air/vacuum release valves shall be placed at all high points or "crowns" in all pipelines. 4. Individual service pressure reducing or check valves are recommended for all new customer service lines in the City. The pressure reducing valves protect customers from high pressures in case of failure of a pressure reducing station. 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. • Cross Connection Control shall conform to WAC 248-54-235 and accepted procedure and practice in Cross Connection Control by Pacific Northwest AWWA. Booster Pump Stations (Source: DOH Policy, City Policy) • All existing and future booster stations should be modified/constructed to comply with the following minimum standards: 1. All structures should be non-combustible, where practical. 2. All buildings should have adequate heating,cooling,ventilation,insulation, lighting, and work spaces necessary for on-site operation and repair. 3. Underground vaults should be avoided where possible due to the increased potential of flooding, electrocution, and other hazards. 4. Sites should be fenced to reduce vandalism and City liability where appropriate. 5. Each station shall be equipped with a flow meter, and all necessary instrumentation to assist personnel in operating and troubleshooting the facility. 7 - 11 CHAPTER SEVEN 6. Emergency power capability shall be provided to at least one booster pump station supplying each booster zone. • Booster stations should be placed wherever necessary to fulfill the following criteria: 1. Provide supply redundancy to a pressure zone. 2. Improve the hydraulic characteristics of a pressure zone. 3. Reduce the cost of water supply. 4. Improve water quality (i.e., increase circulation). Pressure Reducing Stations (Source: City Policy) • The City has a standard design for pressure reducing stations. The standard design reduces design costs and minimizes confusion. • All pressure reducing valves 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. • Pressure relief valves should be provided on the low pressure side of the PRV to prevent System overpressuring 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. Control (Source: City Policy) • Control 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. Maintenance (Source: City Policy) • Equipment breakdown is given highest maintenance priority, and repairs should be made even if overtime labor is involved. • Equipment should be replaced when it becomes obsolete. • Worn parts should be repaired, replaced, or rebuilt before they represent a high failure probability. • Equipment that is out-of-service should be returned to service as soon as possible. • A preventive maintenance schedule shall be established for all facilities, equipment and processes. 7 - 12 POLICIES AND DESIGN CRITERIA • Spare parts shall be stocked for all equipment items whose failure will impact the ability to meet other policy standards. • Tools shall be obtained and maintained to repair all items whose failure will impact the ability to meet other policy standards. • Dry,heated shop space shall be available to all maintenance personnel to maintain facilities. • All maintenance personnel shall be trained in the procedures and techniques necessary to efficiently perform their job descriptions. • 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. Reliability (Source: DOH Criteria, City Policy) • Supply to the service area will be pursued to meet maximum day demand during a reasonable "worst case" supply system failure. • Supply to each pressure zone will be provided to meet maximum day demand _ - during a reasonable "worst case" supply system failure. • At saturation development,interties with adjacent systems may not be reliable or available. • System demand planning will use historical demand data and assume all available land will be developed at saturation. ' Vulnerability (Source: City Policy) • Supply vulnerability analysis will be performed to determine a reasonable "worst case" failure for each pressure zone. The analysis will consider the following condition: 1. Failure of the largest source of supply. 2. Failure of the largest mechanical component. 3. Power failure to a single power grid. 4. Reservoir out of service. • Storage vulnerability analysis will be performed to determine a "worst case" failure for each pressure zone. The analysis will consider the following conditions: 1. Maximum day demand with simultaneous fire. 2. Maximum day demand with largest supply service out-of-service. 7 - 13 CHAPTER SEVEN 111 Joint Use (Source: City Policy) • All joint use facilities must comply with Renton 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 of Renton. • Joint use facilities will be pursued only in those areas that improve reliability or '. operating costs. 6.

INTRODUCTION This chapter compares the existing facilities in the water system, with those needed to comply with policies and design standards identified in Chapter 7. It is divided into four sections: 1) Supply, 2) Storage, 3) Distribution System, and 4) Water Quality. 2. SUPPLY ANALYSIS The purpose of this section is to determine the number and capacity of supply sources required in the water system during current demand conditions and at saturation development. This information will then be used to identify deficiencies in the existing system, and to direct development of new supply sources so that they are compatible with future developments in each operating area. The supply requirements identified in this section are for the existing service area, including Lakeridge Bryn-Mawr Water and Sewer District, using the best available information in land use classification,both existing and saturation. Calculations are based on existing demand data and saturation demand projections listed in Chapter 5. This chapter will not address supply water quality, water supply options, or regional supply impacts. These issues are discussed in Chapter 6. This section will identify supply rates and volumes only, regardless of the origin of the source. Each operating area was analyzed based on the policy criteria listed in Chapter 7,using the five peak demand days in 1987. A saturation supply requirement was calculated by increasing peak demands for the five peak days by anticipated growth in each area. Four separate analyses were performed for each operating area to determine which demand situation requires the largest supply: 1)maximum day demand alone,2) maximum day demand with fire, 3) maximum day demand plus supply failure, and 4) maximum day demand plus replenish standby storage in 72 hours. In each operating area, Situation 2, maximum day demand with a fire, produced the largest supply requirements. A summary of the supply requirements by operating area is listed in TABLE 8-1.

At saturation, all areas will require additional supply capacity PPY ca P Y i except the Talbot Hill 300 Zone. The following improvements are necessary,and are summarized in TABLE 8-2 (Note: All values have been rounded). 8 - 2 System Analysis 1. 196 ZONE: Increase saturation supply by 12,500 gpm. 2.

STORAGE ANALYSIS The purpose of this section is to determine the volume of storage required in the water system during current demand conditions and at saturation development. This information will then be used to identify deficiencies in the existing system, and to direct development of new storage so that it is compatible with future developments in each operating area. The calculation of storage quantities is based on policy criteria adopted for this purpose. The storage requirements identified in this section are for the existing service area, including Lakeridge Bryn-Mawr Water District, using the best available information on land use classification,both existing and saturation. Calculations are based on existing demand data and saturation demand projections listed in Chapter 5. There are three storage components evaluated in this section: 1. Standby storage available during a supply failure. 2. Equalizing storage available to meet non fire demands that exceed supply capacity. 3. Fire storage available to meet fire flow requirements. The State Department of Health recommends procedures to be used for determining the volume of each storage component as follows: standby storage shall be 800 gallons per ERU less the supply rate with the largest source out-of-service, or 200 gallons per ERU, whichever is greater. Equalizing storage shall be that volume necessary to meet instantaneous demands at peak hour above the average rate of the maximum day. Fire flows shall be determined by the Fire Marshall, but shall not be less than 1,000 gpm for two hours. For large water systems like Renton's, standby storage volumes are calculated based on policy decisions, rather than on industry standard requirements. The purpose of standby storage is to provide supply from the reservoirs when the supply system, or parts of the supply system, are out of service. For large systems with many sources of supply,it may be unreasonable to assume that significant portions of the supply system will fail simultaneously. We have therefore performed an analysis of the standby storage volumes needed under four failure possibilities: 1. A failure of the largest supply source to the operating area. 2. A mechanical failure of the largest supply source to the operating area. 3. A power failure in the operating area which may impact supply sources. 4. A reservoir in the zone being out of service for cleaning or inspection. The storage volumes needed for each of these failure possibilities at saturation and existing demand conditions are listed in TABLE 8-4. The storage volume necessary using standard Department of Health (DOH) criteria is also listed for comparison purposes. The worst-case analysis for each zone is used for the standby storage requirement using the following policy: 8 - 6 System Analysis • Standby storage will be provided to supply the water system at the average rate of the maximum day during a "worst case failure" of the supply system. • Standby storage volumes for an isolated service area may be contained in another service area as long as the necessary flow rates can be provided to the necessary zone during a "worst case failure". • Standby storage volumes will be contained in reservoirs at an elevation necessary to provide the highest elevation service in the zone with a pressure of 30 psi at maximum day. • Equalizing storage will be provided to supply peak demands that exceed the average daily demand. • Equalizing storage volumes will be contained in reservoirs atan elevation necessary to provide the highest elevation service in the zone with a pressure of 40 psi at maximum day. • Fire flow storage volumes will be determined by the City Fire Marshal in accordance with flow rates and duration requirements. • Fire flow storage volumes will be calculated using a "worst case" supply system failure.

A saturation storage requirement was calculated by increasing the hourly 8 - 7 CHAPTER EIGHT demands for the 5 peak days by the anticipated growth in each operating area. This procedure assumes that the "shape" of the diurnal demand curve will be the same at saturation as it was for the 5 peak days in 1987. This is a reasonable assumption if the land use in the zone does not significantly change, and if a single large user(such as a bottling plant) does not constitute more than 5%of the supply to the zone. If either of these occur,the storage requirements should be re-evaluated. It should be noted that two different operating areas with the same number of ERUs may not have the same storage requirements. An operating area with a sharply peaking diurnal demand (which is typical of a residential area) will require a larger equalizing storage component than an area with a relatively flat curve (which is typical of a business area). This is evident in Renton where the 565 Zone has an equalizing storage component that is larger than the 196 Zone when compared on an equal ERU basis. For this reason,storage calculations are analyzed by operating area, not combined on a system-wide basis. The criteria for calculating storage in each operating area is listed below. 196 Zone i Equalizing storage is computed by using a mass curve analysis of the 5 peak days in 1987(6/28, 6/29, 7/13, 8/3, 8/4). 290,000 gallons (1987) 2,250,000 gallons (saturation) Standby storage is computed by assuming that the worst case failure is an extended power failure to the well field area for a duration of 3 days. In addition, it is assumed that at saturation Seattle does not have excess capacity and is unable to supply the City through interties. Springbrook Springs is operating with a capacity of 1,000 gpm (after rehab.). 1987 Saturation Demand Requirement 7,548 gpm Demand Requirement 12,036 gpm Supply to Zone 5,185 gpm Supply to Zone 20,135 gpm Supply Deficit 2,363 gpm Supply Deficit 0 gpm Duration of Failure 3 days . Duration of Failure 3 days Standby Volume 10,200,000 gallons Standby Volume 0 gallons Fire flow is calculated by assuming a fire at the Boeing Plant requiring 6,000 gpm for 6 hours. 1987 Saturation Fire flow 6,000 gpm Fire flow 6,000 gpm Duration 6 hours Duration 6 hours Volume 2,160,000 gallons Volume 2,160,000 gallons 8 - 8 System Analysis Highlands 435/Kennydale 320 Zone Equalizing storage is computed by using a mass curve analysis of the 5 peak days in 1987(6/28, 6/29, 7/13, 8/3, 8/4). 110,000 gallons (1987) 1,420,000 gallons (saturation) 1987 standby storage is calculated by assuming that the Mount Olivet Pump Station is out of service due to a discharge main failure for a period of 3 days. The remaining supply to the zone is from the Windsor Hills Pump Station with a capacity of 2,000 gpm. At saturation, standby storage is calculated by assuming the future booster pump station is out of service due to a transmission main failure for a period of 3 days. The remaining supply to the zone is from the Mount Olivet Pump Station(4,400 gpm),Windsor Hills Pump Station(2,000 gpm)and the future Maplewood Booster Pump Station (5,000 gpm). Due to the high cost of providing standby storage in an elevated tank, the standby storage for the 565 Zone will be provided in the 435 service Zone. This is calculated by combining the demands for both the 435 and 565 Zones. 1987 Saturation Demand Requirement 1,868 gpm Demand Requirement 5,200 gpm (435 Zone) (435 Zone) Demand Requirement 2,188 gpm Demand Requirement 6,370 gpm (565 Zone) (565 Zone) Supply to Zone 2,000 gpm Supply to Zone 11,400 gpm Supply Deficit 1,986 gpm Supply Deficit 170 gpm Duration of Failure 3 days Duration of Failure 3 days Standby Volume 8,600,000 gallons Standby Volume 750,000 gallons Fire flow volume is calculated by assuming a fire at the Baxter plant requiring 6,000 gpm for 6 hours. 1987 Saturation Fire flow 6,000 gpm Fire flow 6,000 gpm Duration 6 hours Duration 6 hours Volume 2,160,000 gallons Volume 2,160,000 gallons Highlands 565 Zone Equalizing storage is computed by using a mass curve analysis of the 5 peak days in 1987(6/28, 6/29, 7/13, 8/3, 8/4). 570,000 gallons (1987) 1,710,000 gallons (saturation) Standby storage will be provided in the 435 Zone reservoir,using existing booster pump facilities to supply the standby storage rate of 6,400 gpm. 8 - 9 CHAPTER EIGHT Fire flow volume is calculated by assuming a fire at the Sunset Safeway requiring 5,000 gpm for 5 hours. 1987 Saturation Fire flow 5,000 gpm Fire flow 5,000 gpm Duration 5 hours Duration 5 hours Volume 1,500,000 gallons Volume 1,500,000 gallons Rolling Hills, Talbot Hill Zones Equalizing storage is computed by using a mass curve analysis of the 5 peak days in 1987(6/28, 6/29, 7/13, 8/3, 8/4). 230,000 gallons (1987) 1,000,000 gallons (saturation) Standby storage is calculated by assuming that the transmission main on the Benson Highway is out of service for 5 days.

At saturation demand conditions, the existing reservoirs in the 196 Zone and the West Hill area provide sufficient capacity to meet equalizing and fire flow volumes. Less standby storage is - needed at saturation because of the assumption of the number and location of supply sources to these zones. During a reasonable worst-case"failure,"the remaining supply is sufficient to meet —' saturation demands. It is important to note two points. First,the three storage components(equalizing,standby,fire) analyzed here are not the only bases for providing storage in the system. Storage may need to be constructed in the hydraulically remote areas of the City to maintain acceptable pressures during fire demand or peak hour conditions. Second,it is unreasonable to construct"temporary" __ storage and use it only for a short period of time until saturation supply facilities are in service. We recommend the storage volumes necessary for existing demand conditions be used for saturation requirements also, even if the saturation standby storage component is less then existing requirements. In addition to the storage identified in TABLE 8-5, the distribution system analysis has indicated that additional fire storage is necessary in the Springbrook Springs area and the Black River area to stabilize system pressures during a fire or peak hour conditions. Using this approach, the following improvements are necessary for existing and saturation storage requirements. They are also shown in Table 8-6. 1. 196 Zone: Increase zone storage by 7.0 million gallons. Provide fire flow storage in Springbrook area (2.0 mg). Provide fire flow storage in Black River area (2.0 mg). Provide fire flow storage in Maplewood area (3.0 mg). 8 - 12 System Analysis 2.

DISTRIBUTION SYSTEM ANALYSIS Transmission mains generally convey water between the supply sources (reservoirs or wells)to the local distribution grid, where it is conveyed to the source of the demand. Ideally, under normal demand conditions,minimal head losses should occur in transmission pipelines,allowing these mains to also convey fire demands to the distribution system and to meet other emergencies without experiencing excessive head losses. Under normal conditions, the velocity of water in either transmission and distribution mains should be less than 4 feet per second(fps) during peak demand periods, and less than 8 fps during fire demand periods, so that frictional losses in the pipe are minimal. Computer simulations of the City's System were performed to determine areas with insufficient transmission or inadequate distribution grids. The following criteria were used for these analyses. An area was considered to be deficient if: • Velocities exceeded 4 fps during normal demand and 8 fps during a fire: • Fireflow capacity was insufficient to meet the fire fighting requirements at a particular location; • Pressure criteria listed in the preceding chapter were not met. As a result of the computer analyses of the system, it was determined that the transmission capacity and distribution grid under normal demand conditions is adequate. However, during fire demands,there is inadequate transmission and distribution capacity in certain areas. These areas are described by operating area below: 1. 196 Zone A. Improve reliability of east-west transmission through north end of zone to a 12" hydraulic equivalent with redundancy. B. Increase capacity of north-south transmission through north City area (north of well field) to a 16" hydraulic equivalent with redundancy. C. Improve reliability of existing 24" hydraulic capacity through north-south central corridor via a parallel 24" transmission pipeline. D. Improve fireflow to Renton Shopping Center, 12" hydraulic equivalent. E. Increase capacity to Earlington area, with the hydraulic equivalent of two 16" pipelines. F. Increase hydraulic capacity to Windsor Hills pump station to 24"hydraulic equivalent. G. Improve fire flows to south-west grid. H. Improve reliability of north-south transmission capacity across Grady Way and Interstate 405, 12" hydraulic capacity at two locations. 2. Kennydale 320/Industrial 320 Zone A. Improve fire flows to Boeing and PACCAR areas(industrial 320 Zone)with hydraulic capacity of 24" main. 8 - 15 CHAPTER EIGHT B. Improve north-south transmission capacity along lakefront, 12" hydraulic capacity. C. Improve north-south transmission capacity in north end of zone, east of Interstate 405, 12" hydraulic capacity. D. Increase east-west hydraulic capacity near PRVs, 12"hydraulic equivalent. 3. Highlands 435 Zone A. Improve east-west transmission reliability in north end of zone. B. Improve north-south transmission reliability to City Shop site. C. Improve east-west transmission capacity for reservoir site, 24" hydraulic equivalent. 4. Highlands 565 Zone A. Improve fireflow capacity to east-central area of zone, 12" hydraulic equivalent. 5. Rolling Hills 590 Zone A. Improve transmission reliability to area east of Tiffany Park Pump Station, 8" hydraulic equivalent. i ! B. Improve fireflow to area east of Eagle Ridge, 12" hydraulic equivalent. 6. Talbot Hill 350 Zone A. Improve reliability of north-south transmission capacity, east of Talbot Road, 12" hydraulic equivalent. 7. West Hill Zone A. Improve east-west transmission reliability between Stevens Avenue and 84th Avenue South, 8" hydraulic equivalent. B. Improve fireflow to undeveloped area, 8" hydraulic equivalent. 5. QUALITY ANALYSIS The following improvements are necessary to comply with accepted policies, to eliminate system and water quality deficiencies. 1. Eliminate all dead-end water mains. 2. Utilize Seattle Supply sources for backup only. 3. Improve water quality sampling turn-around time. 4. Prepare a map of Downtown and Golf Course aquifer flow rates and directions under various demand conditions. 5. Eliminate steel pipe. 6. Eliminate asbestos cement pipe. 7. Eliminate lead joint pipe. 8 - 16 System Analysis 6. CROSS-CONNECTION CONTROL PROGRAM The City has completed a comprehensive Cross-Connection Control Program and the Cross- Connection Control Plan is included in the Comprehensive Water System Plan as a separate document. The purpose of the Cross-Connection Control Program is threefold: 1. Identify potential cross connections 2. Administer the installation of control devices 3. Verify the reliability of control devices. The costs to administer the program are based on the addition of staff in the Plan Review and Utility Engineering divisions and are approximately $38,000 per year. If funded from the operating fund, this represents a per customer cost of$0.14 per month. Readers are referred to the Cross-Connection Control Plan for additional details. 7. WATER CONSERVATION PROGRAM The city has completed a Water Conservation Plan, and it is included in the Water System Plan as a separate document. The purpose of the Conservation Plan is: 1. Comply with Department of Health regulations 2. Meet a 6.5% reduction target by 1995 3. Develop program evaluation data 4. Identify effective and efficient conservation tasks. The costs to administer the plan are difficult to predict, since the effectiveness of the program is unknown at this point; therefore, the revenue impacts are unknown. The average monthly customer cost to implement and administer the plan is as follows: 1991 - $0.00 1992 - $0.33 1993 - $0.27 1994 - $0.26 1995 - $0.22 In addition,each 1%of conservation savings has a rate impact of$0.13 per customer per month. 6.

It is shown in two formats, one showing growth as a function of time (years), and the second showing growth as a function of Equivalent Residential Units(ERU). The ERU chart can be used to plan system supplies sources, even if the actual growth rates are substantially different than actual growth rates. The ERU designation can be used as the triggering criteria • for new source development.

INTRODUCTION This chapter presents the improvements that are necessary in the Renton System to resolve existing deficiencies and accommodate growth. The costs of the improvements and a schedule for improvements implementation are also included. Chapter 7 presented the policies, and performance and design criteria, to be used in identifying existing deficiencies and in planning for system growth. Chapter 8 compared these policies with the existing system and the anticipated saturation demands,then compared the existing facilities with those needed to comply with policy and design standards. System improvements are presented in this chapter in this order: 1. A list of each proposed improvement by pressure zone, with a brief description of the criteria used, the estimated current cost of the improvement, and the recommended year of!construction based on priority. 2. A summary of improvements by CIP project number. 3. A cost summary of the improvements by project number, and a schedule for implementation (TABLE 9-1, found in the back of this chapter). In addition, the recommended improvements are shown in plan view in FIGURE 5, and in hydraulic profile in FIGURE 6. In FIGURE 5,the 5-year CIP projects are identified with a blue legend, and saturation projects are identified with a black legend. While this chapter identifies specific capital improvements necessary to meet policy requirements and accommodate growth,the City does not currently have a sinking fund to replace the existing water system facilities as they reachthe end of their service life. Beginning in 1994, a sinking fund will be established with a contribution of$250,000 per year. 2. DOWNTOWN 196 ZONE Mount Olivet Reservoir No. 2 Construct a second reservoir on the'Mount Olivet Reservoir site with a capacity of 2.0 million gallons, and an overflow elevation of 196 to match the overflow of the Talbot Hill reservoir.

This reservoir will provide 3.0 million gallons of the 4.7 million gallons additional capacity necessary in the 196 Zone. The reservoir will also stabilize pressures in the Maple Valley area during fire flows and peak demand conditions. CIP Project No. 19 Cost: $3,715,000 Completion: 2000 196 Zone Reservoir at the Springbrook Springs site Construct a water storage reservoir in the Springbrook Springs area,with a capacity of 2.0 million gallons and an overflow elevation of 196. This reservoir will be used to provide fire flow storage and to stabilize pressures in the south Renton area during a fire or peak demand conditions. Storage in this area is not hydraulically useable in the downtown area and therefore cannot be used to satisfy the additional 4.7,million gallons of additional saturation storage necessary. The reservoir sizing is based on fire flow requirements in this area.

This reservoir will be used to provide fire flow storage and to stabilize pressures in the west section of the 196 Zone during a fire or peak demand conditions. Storage in this area is not hydraulically useable in the downtown area and therefore cannot be used to satisfy the additional 4.7 million gallons of saturation storage necessary. This reservoir will also provide a hydraulic control surface for the suction of the Black River Pump Station, and is sized based on fire flow requirements in this area of the City. CIP Project No: 55 Cost: $2,750,000 Completion: 2005 Maplewood Golf Course Well Numbers 10, 11, 12, 14, and 17 Construct wells (and booster station facilities) in the Maplewood Golf course area to supply 10,400 gallons per minute(gpm)to the 196 Zone(1,600 gpm of the 12,000 gpm saturation supply deficit in the 196 zone will be supplied by Well Number 5 into the 435 pressure zone,which will reduce the loading on the supply to the 196 zone). Well numbers 11 and 17 are expected to be operational by 1992 and supply 4,000 gpm(1,500 gpm and 2,500 gpm respectively). Well number 14 must be operational by 1996 and is expected to provide 2,500 gpm. Well number 12 must be operational by 2005 and is also expected to produce 2,500 gpm. Well number 10, which is expected to produce 1,400 gpm, must be operational by 2015. If the anticipated yields of these 9 - 2 System Improvements wells is incorrect, additional wells will need to be constructed to match the system growth shown in TABLE 8-6.

KENNYDALE 320 ZONE Kennydale 320 Zone Reservoir Construct a water storage reservoir in the northern-most area of the 320 Zone with a capacity of 3.0 million gallons. This reservoir will provide 3.0 million gallons of the 7.3 million gallons storage deficit in the Highlands 435 and Kennydale 320 zones. Construction in this zone will —� improve operating efficiency, since water used in the 320 Zone would not need to be pumped.to the 435 Zone first. It will also improve supply reliability in the northern area of the City by providing an additional supply source during a transmission main failure. Perform site study and acquisition in 1991.

HIGHLANDS 435 ZONE Highlands 435 Reservoir Site Construct a.second reservoir on the existing Highlands 435 Zone Reservoir site, with a capacity of 4.0 million gallons and an overflow elevation of 435. This reservoir will supply 4.0 million gallons of the 7.3 million gallons storage deficiency in the 435/320 zones at saturation. The remainder of the storage necessary in this zone will be in the Kennydale 320 Zone Reservoir(the actual remaining capacity of 3.3 million gallons has been rounded up to 4.0 mg). This reservoir also contains the standby storage necessary in the Highlands 565 Zone, since construction of a ground-level reservoir is less expensive than an elevated tank in the 565 Zone. CIP Project No: 5 Cost: $3,875,000 Completion: 2020 South Highlands 435 Zone Reservoir (Reservoir Site No. 2) This reservoir site is a preferred alternative to a reservoir at the existing reservoir site and should be constructed in lieu of that reservoir (Project No. 5)if property can be acquired. This location will help to stabilize pressures in the southern portions of the 435 Zone. Although pressures in this area are adequate, the pressure stabilization is still beneficial. Sizing considerations are the same. This cost would be in lieu of Project No. 5. . CIP Project No: 13 Cost: $4,875,000 Completion: 2020 Windsor Hills Pump Station Rehabilitation Rehabilitate the existing Windsor Hills Pump Station to increase pumping capacity by 1,200 gpm. This will provide 1,200 gpm of the 11,200 gpm supply deficiency in the 435 Zone. The remaining 10,000 gpm will be provided by the South Highlands Pump Station and the 9 - 8 System Improvements I Maplewood Pump Station(which will supply the 565 Zone and therefore reduce the loading on the 435 Zone). As an alternative, construct a new pump station at the intersection of the 196/435/320 zones and replace the Windsor Hills and proposed Coulon Park pump stations with a single structure. CIP Project No: 10 Cost: $364,000 Completion: 1990 ' I South Highlands Pump Station Construct,a booster pump station in the Maple Valley area to pump from the Downtown 196 Zone to the Highlands 435 Zone with a capacity of 5,000 gpm: This will provide 5,000 gpm of the 11,200 gpm deficiency in the 435 Zone (the remaining 6,200 gpm will be provided by the Windsor Hill Pump Station rehabilitation [1,200 gpm] and the Maplewood Pump Station [5,000 gpm]).

This reservoir will provide all of the 2.0 million gallon deficit necessary for saturation development. The reservoir should be located on the Hunter property,which has been acquired by the City for this project. CIP Project No: 6 Cost: $3,362,000 Completion: 2000 Maplewood Booster Construct a booster pump station in the Maplewood Golf Course to pump from the 196 Zone to the Highlands 565 Zone with a capacity of 6,000 gpm. The pump station will provide all of the 6,000 gpm supply deficit needed for saturation development. Initially, the pump station should be constructed with a capacity of 5,000 gpm, with the capability to upgrade to 6,000 gpm in the 9 - 10 System Improvements future. The upgrade in booster capacity should coincide with the development of wells in the Golf Course area. The booster pumps must be constructed in conjunction with the well facilities, since they are the only method of pumping water from the wells to the distribution system.

ROLLING HILLS 590 ZONE Maplewood Booster Construct a booster pump station in the Maplewood Golf Course area to pump from the 196 Zone to the Rolling Hills 590 Zone with a capacity of 5,000 gpm. The pump station will provide 5,000 gpm of the 7,300 gpm supply deficit needed for saturation development. The booster must be constructed in conjunction with the well facilities, since they are the only method of pumping water from the wells. The majority of the supply will be used in the 490 Zone, andcan be transferred to the 490 Zone from the 590 zone reservoir by installing a control valve in the proposed 490 Zone Booster Station to route water from the 590 Zone Reservoir to the 490 Zone Reservoir. The details of this procedure can be found in the pre-design report for the Rolling Hill Reservoir(the 490 Zone distribution system is not accessible to the Maplewood Booster without unnecessary transmission main expense). CIP Project No: ' 20 Cost: Included in Wells 11 & 17 costs Completion: 1992 490 Zone Pump Station Construct a booster pump station on the 590 Zone Reservoir site to pump from the 490 Zone to the 590 Zone with a capacity of 6,100 gpm. .The booster station will be used to supply maximum day demands of 1,100 gpm in the 590 Zone, and also provide 5,000 gpm of fire protection to the 590 Zone when the Maplewood Booster Station is out of service. This booster is a redundant supply to the Maplewood Booster Station. The station will also be equipped with a valve to transfer water from the 590 Zone to the 490 Zone Reservoir.

ROLLING HILLS 490 ZONE 490 Zone Reservoir Construct a second reservoir on the existing Rolling Hills Reservoir site with a capacity of 5.0 million gallons and an overflow elevation of 490. This reservoir will provide all of the storage deficit necessary in the 490 Zone for saturation. This reservoir also contains the standby storage necessary in the Rolling Hills 590 Zone, since constructing a ground level reservoir is less expensive than an elevated tank lin the 590 Zone. (It should be noted that this reservoir is smaller than the reservoir recommended in the Rolling Hills Reservoir pre-design report. In the pre-design report,it was assumed that the reservoir construction would precede the construction of the Maplewood Facilities and the additional reservoir capacity was necessary to provide service when one reservoir was out of service for cleaning. We recommend that an amendment be prepared for the Rolling Hills Reservoir pre-design report which determines if this 5.0 million gallons should be constructed in one or more phases.) This project also includes installing a111) fourth pump in the No. Talbot Hill pump Station to raise pumping capacity into the zone by 2,300 gpm to meet saturation demand conditions. The remaining 5,000 gpm deficit will be providedby either the,Maplewood iPump Station or the Scenic Hill Pump Station. CIP Project No: 26 Cost: $3,200,000 Completion: 1995 Scenic Hill Pump Station (located near City Hall) Construct a booster pump station in the Scenic Hill area to pump from the Downtown 196 Zone to the Rolling Hills 490 Zone with a capacity of 5,000 gpm. The station will provide 5,000 gpm of the deficit supply requirement of 7,300 gpm for the 490 Zone. The remaining 2,300 gpm will be provided with the pump addition at the North Talbot Hill Pump Station. This Pump Station is necessary as a backup supply to!the zone in the event that the Maplewood Booster is out of service. This project also includes water transmission lines from the Pump Station to the 490 Zone.

WEST HILL 495/270 ZONES Black River Pump Station Construct a booster pump.station in the Black River area to pump from the Downtown 196 Zone ill to the West Hill 495 Zone with a capacity of 2,400 gpm. The 2,400 gpm will provide more than the 900 gpm deficit at saturation development; however, the Pump Station is necessary as a. backup supply to the zone in the event that the West Hill Booster Station is out of service. This station should therefore duplicate the capacity of the West Hill Station,which is 2,400 gpm. The construction of this station will provide supply redundancy for the West Hill area to reduce the. -- standby storage necessary in the West Hill Reservoir.

Mr. Sled supervises the day-to-qday activities of three divisions. The Technical Division maintains and operates the automatic control system, the water quality and treatment system, and the pump stations and reservoirs. The Maintenance Division installs improvements,meters, main extensions, and other construction-related activities. The Inventory Division maintains tools, consumables and rolling stock. The Mandatory Water Works Operator Certification Law specifies that certain responsible positions be staffed by individuals who hold the appropriate operator certificate. In the case of Renton,the Water Maintenance Supervisor must be certified as a"Water Distribution Manager IIT". Mr. Sled holds a WDM IV certification and therefore exceeds state requirements for certification. The certifications held by the remaining staff are listed in TABLE 10-2. All personnel are also certified as Cross Connection Control specialists and Mr. George Stahl, who is responsible for the automatic control system, is also an electrician. In-service training consists of special courses and seminars specifically designed for the requirements of an employee group. The training is offered through such organizations as the American Water Works Association (AWWA), local section; various trade organizations, local colleges and universities; Seattle-King County health departments by some of the larger water utilities; and by industrial training specialists. Renton's policy of supporting and promoting operator training should be continued. 10 - 1 TABLE 10-1 WATER MAINTENANCE ORGANIZATION 1J PUBLIC WORKS DIRECTOR Lynn Guttmann FIELD MAINT.

New employees need orientation and basic information while more experienced employees can improve by continued training for update and review. The importance of training opportunities and their impact is such that training should be linked in with the overall personnel evaluation program. Of equal importance to the personnel evaluation program and to the goal of maintaining an effective staff is a promotional plan. A definite promotional policy closely linked with an employee training program is of primary importance in developing improved competence and proficiency. An important point regarding training is that mandatory certification is required by the State. Qualifications and training requirements for obtaining and maintaining certification are stipulated by the State Department of Social and Health Services (DSHS). The City Council and Administration have approved expenditures for increased training, with the result that improved proficiency levels have occurred in the last five years. Communication Efficient and economical functioning of a team requires adequate provision for regular, effective communication among its members. The normal channels and equipment available to maintain effective inter-staff communication are: 1. Vehicular two-way radios 2. Regularly-kept work logs 3. Regular inspection reports 4. Daily work assignment meetings 5. Inventory and other recordkeeping practices 6. Emergency phone numbers for "on-call" employees 7. Direct, City-owned telephone connection to City Hall The water utility does not have a comprehensive system operation manual; however, facility operation and maintenance(0 &M)manuals are available for staff reference. The City intends to maintain its policies of requiring complete operation and maintenance manuals for all new equipment. In addition,we recommend that a system-wide 0&M manual be prepared and updated on a regular basis. 10 - 3 CHAPTER TEN Equipment Availability Water Maintenance is equipped primarily with rented equipment. The equipment available-for daily use includes rolling stock, and inventory of shop tools and equipment, as well as other portable equipment for field use. The vehicles and other rolling stock are listed in TABLE 10-3 with a description of their primary use in the department. Subsequently, the other field equipment and the shop equipment are listed in summary form.

The City should examine the backup capabilities of the inventory based on critical equipment failure and make provisions for additional equipment procurement on a short-notice basis where necessary. Routine Operations Routine operations involve the analysis,formulation,and implementation of procedures to ensure that the facilities are functioning efficiently and meeting pressure requirements and other demands of the system. The utility's maintenance procedures are good,with repairs being made promptly so customers receive high quality water service. A detailed description of the existing control capabilities and the proposed control improvements is contained in Chapter 3 of this Plan. The City has adopted an aggressive policy of providing and relying on automatic controls for the routine operation and recordkeeping needs of the Water System. This will allow the existing operations staff to concentrate on preventive maintenance, equipment repair, and the other;specialized needs of the Department, while eliminating the "human factor" from routine tasks and increasing System efficiency and reliability. _ State law and good management require an ongoing water quality monitoring program. The City of Renton follows the testing procedures and recordkeeping requirements of the Washington 10 - 5 CHAPTER TEN State DSHS,WAC 248-54-165. The Department of Health(DOH)has adopted regulations that specify sampling frequencies for physical, bacteriological, and chemical (organic and inorganic) constituents and radionuclides. The sampling requirements depend on the number of customers, source, type, and treatment provided. The specific requirements are contained in WAC 248-54- 740 and are summarized in Table 3(pages 25 and 26)of the "Rules and Regulations of the State Board of Health Regarding Public Water Systems." Renton has developed a water quality sampling and recordkeeping program that ensures compliance with the regulations. Samples are collected from the Distribution System and submitted to a state-certified laboratory for bacteriological analysis in compliance with Table 2 in the above-referenced rules. With the current population served of approximately 37,000, 60 samples per month of finished water and 20 samples per month of raw water are collected. The City uses the following sampling schedule: Inorganic Analysis Every 3 years Volatile Organic Compounds Every 3 months Bacteriological Samples Every week In addition,the State samples for Trihalomethanes once per year. The City uses a combination of State and local laboratories for water quality analysis results. The State lab requires 8-10 weeks to return results, and the local labs return results in 3-5 weeks. This is an unacceptably long time if the public's health is to be protected from groundwater contaminations in the aquifer recharge area. We recommend that the City acquire equipment and maintain a self-contained water quality laboratory at the shop site. Distribution system sampling points are shown in FIGURE 1. Records Providing time for keeping and maintaining accurate records should be an integral consideration in determining the time to be allotted to any departmental task. Adequate records are an essential tool in utility management and operation, and providing the supporting data for operations assessment and long-term planning, while saving time and reducing difficulty when trouble arises. The Water Utility has need for several types of records: operational records (flow and level recordings), chlorination station records,main disinfection records, personnel records, customer • contact records,meter records,inventory records,and mandatory water quality sampling records. These and other appropriate documents should be legible,clear in format,permanent, accurate, and accessible. Their importance to the efficient functioning of the Utility is effectively addressed in the context of the in-service staff training sessions. Up-to-date maps of the water system are important for operation and maintenance. Changes or additions to the water system should be added as they occur. The City maintains an updated 1"= 400' scale map of the water system that is useful to the operations and maintenance staff, and a set of 1"= 100' utility maps. The 1"= 100' utility maps show the water line sizes, the location of valves, the status of the valve(whether open or closed)during normal operation, and an indication of the locations of service connections. This information is useful in helping the 10 - 6 Operation and Maintenance operation and maintenance staff to locate water lines,valves, and service connections from these maps. Plat maps or construction drawings for new water mains or transmission lines within the distribution system should also be filed as backup information for the water system. The City is currently in the process of installing a data-logger recording system on the Telemetry and Supervisory Control System,'which will assist in recordkeeping management. Cross Connection Control The Renton Water Utility has an ongoing cross connection control program and the Utility ensures the program conforms to WAC 248-54-285. The Utility has adopted the "Accepted Procedure and Practice in Cross Connection Control"published by the Pacific Northwest Section of AWWA as its standard of practice. A backflow prevention device or other approved device is required on all cross connections or possible cross connections. Each device is required to be inspected and tested each year. Installation of backflow prevention devices is in conformance with the Uniform Plumbing Code, and is enforced by Renton's Building Inspection Division. Mr Ron Druce is the designated cross connection control specialist for the City's backflow preventors. The City has implemented a Cross Connection Control Program and prepared a Cross Connection Control Plan. The Plan is included in this Comprehensive Water Plan as a separate document. • 2. EMERGENCY OPERATIONS The City of Renton has prepared an Emergency Response Plan that identifies how Renton should react to an emergency, including the functions and responsibilities of personnel, procedures to be followed,maps of each facility, contact lists, and communication procedures. The emergency response procedures are available both in report form and through a computer program prepared specifically for this purpose. The Emergency Response Plan should be updated every two years. The reader is referred to the Emergency Response Plan document for additional details. In addition, the City has prepared a Water Shortage Response Plan that identifies procedures to be used for reacting to a reduction in water supply or a large demand that exceeds the supply system's capacity. The plan lists various conservation and supply augmentation options. It should be updated every two years. 3. PREVENTIVE MAINTENANCE Maintenance schedules that meet or exceed manufacturer's recommendations should be established for all critical components in the Water System. The following schedule should be used as a minimum for preventive j maintenance: Supply Sources Daily: Observe and record motor current draw (three phases); check packing; log and record volume delivered and pump motor hours; check motor pumping water level; check motor noise, temperature, vibration. 10 - 7 CHAPTER TEN Weekly: Check security. Semiannually: Change motor oil. As Needed: Paint structures and piping; maintain electrical and hydraulic controls. Storage Facilities Weekly: Check security. Annually: Check interior condition, vents, hatches, etc. on tanks. As Needed: Repaint interior and exterior as needed on tanks (estimated 10 to 15 year frequency). Distribution System Booster Pump Station - Same as Supply Sources Pressure Reducing Stations Annually: Check all valves; check screens, and pressure settings; rebuild, as necessary. Pipelines Annually: Flush dead-end lines Valves Annually: Operate full open/closed; uncover where buried; clean out valve boxes, etc., repair as necessary. Leak Survey and Isolation Hydrants Semiannually: Operate;check drain rate;lubricate as necessary;measure pressure; paint as necessary. Meters 10 Year Intervals: Replace 3/4" to 2" meters, and inspect all parts, replace worn or defective parts; retest meter for accuracy. Annually: Inspect all 3" and larger meters and test. 10 . 8 Operation and Maintenance Control Equipment Semiannually: Check calibration of transducers and primary sensing units; adjust as necessary. As Needed: Replal a light bulbs. Replace failing equipment. Tools & Equipment Rolling Stock Daily: Check all fluid levels and brakes. As Needed: Replace fluids and filters in accordance with manufacturer's recommendations (or more frequently depending on type of use). Tools As Needed: Clean after each use; lubricate and maintain as necessary. Meter Testing The City currently has a program to periodically test the accuracy of the reading obtained from individual water meters. 4. STAFFING The preventive maintenance procedures, and normal as well as emergency operations of the utility, are described in the previous sections. The hours of labor and supervisory activity required to effectively carry out they work of these on-going maintenance and operations schedules form the basis for determining adequate staffing levels. Current Staff The current staff organization is illustrated in TABLE 10-1. There are at present 18 employees, including supervisory personnel, technicians, maintenance workers and office staff, engaged in operating and maintaining the Water System. The tasks which are performed by water utility staffinclude inspection,testing,installation and repair of system facilities and routine preventive maintenance, recordkeeping, administrative tasks, general clerical work, and corrective or breakdown maintenance required in response to routine emergencies. The hours of work required to adequately maintain the Water System (excluding supervisory time, time associated with the work needed to accommodate expansion or growth [i.e., pipe laying,new service connections,etc.], and time required for clerical tasks)are shown in TABLE 104. For the preventive maintenance alone, the annual hours total 16,920, or 325 crew hours per week. This requires a minimum of 8-plus crew members working full time;i.e.,40 hours per week, excluding vacation, sick leave, and all other tasks not related to preventive maintenance. As indicated in TABLE 10-1, there is presently a total of nine water department maintenance crew members employed by the City. 10 - 9 CHAPTER TEN TABLE 10-4 STAFFING TIME FOR PREVENTIVE MAINTENANCE Minimum Quantity in Time per Time Required Facility or Equipment Frequency of System Unit per Year Maintenance (# of units) (Hours) (Hours) Hydrants Semi-annually 2,000 .25 500 • Large Valves (16" or larger) Annually 215 4 860 Distribution Valves Every 10 years 4,100 1.3 5,330 Meters Every 10 years 11,300 2 2,260 Mains Leak Survey Annually 210 miles 10 2,100 Poly Pigging 10 miles/year 210 miles 100/mile 1,000 Booster Pump Station * 10 120 1,200 Pressure Reducing Station * 33 32 960 Wells/Springs CLz + Fluoride * 5 350 1,750 Reservoirs * 6 120 720 Control System Semi-annually 1 240 - TOTAL 16,920/year * Daily,Weekly, or as needed;varies with component and task. If, in addition, due consideration is given to the hours involved in vacation, holiday, illness, meetings, training, on-the-job travel and startup time, then the total number of hours actually available for performing the work of operation and maintenance diminishes to a level of approximately 1,662 hours per year per crew member. At this rate, a staff of 11 full-time maintenance crew members is adequate to accomplish minimal preventive maintenance with no time available for normal operations activities, emergencies, or new connections. TABLE 10-1 indicates the current size of the maintenance crew. TABLE 10-5 lists the staffing time necessary for work not associated with preventive maintenance (operation). TABLE 10-5 STAFFING TIME FOR OPERATION TASKS Activity Frequency Per Activity Total Time Monitoring System Operation Each Station Daily 1/3 hour 1,806 Hrs/Year Checking on Facilities (false alarm 100 per year 1 hour 100 Hrs/Year response) Meter Reading(Finance Department) 4 per year 1/6 hour 6,933 Hrs/Year , 10 - 10 Operation and Maintenance TABLE 10-5 STAFFING TIME FOR OPERATION TASKS Activity j Frequency Per Activity Total Time Groundskeeping 1 per year per 2 per day 2,000 Hrs/Year Facility (May to October) • Inventory (Shop) 2,076 Hrs/Year Repair & Replacement(of meters) 1 1,300 per year 2 hours 2,600 Hrs/Year Main Breaks 3 per month 40 hours 1,440 Hrs/Year System Failures 4 per year 24 hours 96 Hrs/Year Hydrant Repairs 100 Annually 24 hours 2,400 Hrs/Year New Service Connections 10 per month 16 hours 1,600 Hrs/Year New Main Connections 2 per month 4 hours 96 Hrs/Year Reservoir Sanitary Checks 40 per month 1/3 hour 960 Hrs/Year Water Quality/Water Testing 100 tests/week 6 hours 312 Hrs/Year Administration 3,324 Hrs/Year TOTAL 27,743 Hrs/Year The total operation and preventive maintenance time required is 44,663 hours per year,or more than 27 persons working full-time (40 hours per week). These figures indicate that the Department is not adequately staffed to regularly perform the basic tasks required to provide even minimum recommended maintenance to the system. An expansion of the system necessitating new service connections and/or additional facilities, without enlargement of the staff, will result in increased neglect of necessary maintenance. In view of predicted population growth in the service area over the next several decades and the concomitant growing demand for water supplied by an increasingly complex system, the unavoidable conclusion is an immediate and continuing need for additional staffing. There are many arguments to support the wisdom of adequate staffing in any workplace. One of the most persuasive arguments relevant to a complex Water System concerns the neglect of preventive maintenance schedules which tends to accompany short-staffing. Routine, regular preventive maintenance tasks are,often the first to be dropped from the schedule when the time available is inadequate to do the job properly. The resulting misfortune is usually increased breakdown maintenance and excessive reliance on an expensive abundance of standby equipment required to circumvent service outages during emergency repair. The preventive maintenance tasks listed in TABLE 10-4 account for approximately 40% of the total number of hours required. 10 - 11 CHAPTER TEN Additions Necessary Regular performance of all necessary work in the Department, with the current number of service connections, will require additions to the present maintenance crew. The expected increase in the number of service connections should serve as further impetus to develop a staff of an adequate size to effectively operate and maintain the System. The size of the maintenance crew should be increased from 9 crew members to 11 personnel. The size of the operations crew should be increased to 16 personnel. These additions to the staff will be required before there are adequate crew hours available to carry the full work load of the Utility without neglecting preventive maintenance, emergency preparedness, or safety precautions. Maintenance and technical staff additions should be accompanied by additions to the clerical,secretarial and other support staff needed to assure that recordkeeping,billing, public relations, communications, and other general functions of support staff are performed with the accuracy, timing and regularity required. I 10 - 12 Chapter Eleven FINANCIAL 1. INTRODUCTION This chapter considers the financial impacts of constructing the improvements recommended in Chapter 9. In order to assess the impacts, the estimated current costs of the proposed improvements are compared with the anticipated operating and maintenance costs of the sewer utility to develop income requirements. The income requirements are then compared with anticipated revenues to determine the level of rate increase necessary to support the Capital Improvement Plan recommended. A utility rate study has recently been completed, and the results of the rate study were used for portions of this chapter. The reader is referred to the rate study for additional details. 2. IMPROVEMENT COSTS The estimated costs to construct the improvements identified over the five-year period from 1989 to 1994 are summarized in this section. Although the anticipated costs for all of the improvements have been estimated, it is difficult to develop good financial planning data for more than a five-year period. Changes in system flowrates system growth, financial policies, regulatory requirements, and rate structures all contribute to limit the benefits of long-range planning. It is our recommendation that financial goals be evaluated every five years and that detailed financial planning be limited to this time frame. The five-year Capital Improvement Costs are summarized below: Year Capital Improvement Costs* 1989 $355,000 1990 $1,976,000 1991 $2,060,000 1992 $3,362,000 1993 $3,112,000 1994 $2,410,000 *. These costs are slightly higher than the costs shown in Chapter 9 due to the inclusion of Debt Issuance Costs. 3. OPERATING COSTS The estimated costs to operate the Sewer Utility include salary and METRO costs for both the Operation and Maintenance and Engineering and Administration services,taxes,office supplies, debt service, and consulting fees. Forecasting for operating costs requires assumptions regarding level of service, growth, and inflation. The level of service is expected to increase yearly and approach the recommended staffing levels within a 10-year period. Growth is assumed to occur at 2%per year, as identified in Chapter 5. Inflation for labor is estimated to be 5% annually plus a 5% step increase 11 - 1 CHAPTER ELEVEN applicable to 50%of the work force. Other expenses are anticipated to increase at a rate of 5%. Metro treatment services are forecast to increase at an annual rate of 16%. The estimated operating costs are summarized below: Year Estimated Operating Cost Estimated Operating Costs (City Services) (METRO Treatment Services) 1989 $4,319,000 $2,687,000 1990 $5,195,000 $3,074,000 1991 $5,738,000 $3,655,000 1992 $6,100,000 $4,394,000 1993 $6,525,000 $5,226,000 1994 $7,155,000 $6,222,000 4. REVENUE The estimated revenue for the Sewer Utility includes service charges, connection fees, development fees, investment interest, contributed capital, grants, and revenue bond proceeds. The revenue was forecast using the 1990 budget as a base rather than using actual expenditures. During 1989, the Public Works Department underwent an extensive re-organization, and the 1990 budget reflects the new organization. The estimated revenue is summarized below: Year Estimated Revenue 1989 $ 4,783,000 1990 7,132,000 1991 8,072,000 1992 10,697,000 1993 9,794,000 1994 11,198,000 5. FINANCIAL ANALYSIS TABLE 11-1 summarizes anticipated revenues and expenses for the Sewer Utility. The budget deficit shown in TABLE 11-1 in 1989 and 1990 is funded with cash reserves that are replenished in subsequent years through the recommended rate increase. (Note:Although every attempt has been made to make this Comprehensive Plan compatible with the 1989 Rates Analysis, several Capital Improvement Projects that were identified after the publication of the Rates Analysis have changed the yearly C.I.P. expenditures.) 11 - 2 Financial TABLE 11-1 REVENUE AND OPERATION SUMMARY (1000s of Dollars) 1989 1990 1991 1992 1993 1994 Expenses Capital Improvement Costs 355 1,967 2,060 3,372 3,112 2,410 Operating Costs 4,428 5,165 6,012 7,211 8,492 9,892 SUBTOTAL 4,783 7,132 8,072 10,583 11,604 12,302 Revenue Capital Improvement Source 309 1,967 2,060 3,372 3,112 2,410 Operating Sources 4,050 6,166 6,012 7,211 8,492 9,892 SUBTOTAL 4,359 8,133 8,072 10,583 11,604 12,302 Surplus (or Deficit) (445) 1,001 0 0 0 0 Annual Rate Increase Required (%) 42.17 11.92 19.75 13.89 9.82 The rate increase shown is the amount necessary to support the expenses identified in the Capital Improvement Program and the anticipated operating costs of the sewer utility,using the following sewer rate schedule for 1989.

RATE COMPARISON TABLE 11.2 shows a comparison of sewer rates between the City of Renton and several adjacent sewer systems. The comparison uses the 3/4"residential meter rate,which is the primary source of system revenue. It can be seen that Renton compares favorably to rates charged by other municipalities in this - region. The competitive rates and high service quality are a result of the following: 11 - 3 CHAPTER ELEVEN 1. Efficient operation 2. A revenue basis wherein existing customers are not paying for improvements to accommodate growth. 3. Exhaustive efforts to reduce the sewer utility budget. 4. Successful pursuit of grant funding for eligible items. 11 - 4 Financial TABLE 11-2 1989 WATER RATE COMPARISON AGENCY • WATER SEWER COMBINED RATE RATE RATE Renton $15.00 $4.80 $19.80 Tukwila 17.30 4.50 21.80 Kent 16.80 6.20 23.00 Auburn 10.00 4.50 14.50 Seattle 10.50 .14.00 24.50 Bellevue 9.80 3.50 13.30 Redmond 15.90 5.70 21.60 Kirkland 14.00 5.00 19.00 WD 107 16.40 6.50 22.90 Soos Creek 12.00 6.60 18.60 • $25.00 777 • • • • $20.00 •• ill • ici iiii iiii ii "iii $15.001-iiii-iiii Ilii ii i i "" II' Iiii v 'IIR.4 I, ,iii n P h II��N ,r!I I i. i I !i iii t 0 41 :: pii t l r1 - 'g � J . iii ` ' 1 ih, :iii: iiii iiii- I.f_ ,I.

WATER SYSTEM PLAN FOR THE CITY OF KENT, URS Company, October, 1979 APPENDIX C SEPA CHECKLIST A. BACKGROUND 1. Name of proposed project, if applicable: City of Renton, Comprehensive Water System Plan (1990) 2. Name of applicant: City of Renton 3. Address and phone number of applicant and contact person: Ron Olsen Utility Systems Division City of Renton 200 Mill Avenue Renton, WA 98055. 277-6207 4. Date checklist prepared: February 17, 1992 5. Agency requesting checklist: City of Renton 6. Proposed timing or schedule (including phasing, if applicable): The Comprehensive Water System Plan identifies improvements to the City's Water System for two planning periods. The primary focus of the plan is improvements that are needed over the next five years. These improvements are to be included in the City's five- year Capital Improvement Program. Other improvements are identified for the "saturation" condition, which is projected to be about the year 2040. 7. Do you have any plans for future additions, or further activity related to or connected with this proposal? If yes, explain. The City has completed or is preparing a number of related plans. These include an Emergency Response Plan, which is currently being prepared, and a Water Shortage Response Plan. Copies of the Conservation Plan and a Cross Connection Control Program are attached. In addition, State regulations require that the City update its Comprehensive Water System Plan every five years. The City is also in the process of updating its Comprehensive Land Use Plan. When completed, implementation of the new land use plan will be incorporated into the Water System Comprehensive. Implementation of the Water System Plan will also be C - 1 APPENDIX C coordinated with. the City's .Park & Recreation and Trails Master Plans. An Environmental Impact Statement (EIS) is being prepared for these Master Plans. 8. List any environmental information you know about that has been prepared,or will be prepared, directly related to this proposal. Except for those projects that are categorically exempt, each project listed in the Comprehensive Water System Plan is subject to SEPA review and individual SEPA determinations. For example, the development of Wells 11 and 17, currently underway on the Maplewood Golf Course, were reviewed by the Renton Environmental Review Committee and given a Mitigated Determination of Nonsignificance and a Determination of Nonsignificance, respectively. In 1989, the City issued a Determination of Nonsignificance for the rezoning of 13 parcels owned by the City Utility. In 1987, a special study was done regarding the issue of hydraulic continuity between the City's aquifer and the Cedar River. The report documented that continuity existed. It is minimal(within measurable limits); and within the approved limits of the Washington State Instream Resources Protection Program. A copy of these reports is attached to this SEPA Checklist document. Additional information will be provided based on a final determination of changing requirements imposed by the State as part of the water right acquisition process. 9. - Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. The proposal is not site specific; therefore, this question does not apply. 10. List any government approvals or permits that will be needed for yourproposal, if known. Approval by both the City Council and the Washington State Department of Health (DOH) is required. Approval by the King County Utilities Technical Review Committee and the King County Council is required for service-to the small-unincorporated areas served by Renton. In addition, implementation of the various physical and programmatic changes included in the Comprehensive Water System Plan may require approvals from one or more of the following agencies: • Washington State Department of Health (Plan approvals) • Washington State Department of Ecology (Water Rights) • Washington State Department of Transportation (Right of Way Franchises) • Washington State Department of Fisheries (Hydraulic Project Approval) • King County (Right of Way Construction Permits) 11. Give a brief,complete description of your proposal,including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not C - 2 • SEPA Checklist need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) �, The Comprehensive Water System Plan addresses water supply, transmission, and storage needs for the City's planning Area. The major purpose of the plan is to identify transmission, storage and distribution systems necessary to serve the estimated population at saturation. The plan addresses groundwater, aquifer protection, water quality, operation and maintenance, and financing issues. Future water supply is also discussed. The "No Action Project Alternative" would result in: 1) the inability of the City to obtain State and grant funding by virtue of not having an approved Water Comprehensive Plan, 2) not being in compliance with the State Department of Health regulations which mandate and updated and approved Comprehensive Plan every five years, and 3) the inability for the City to proceed with implementing of projects necessary to continue to provide a safe, adequate, and reliable water system. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposal, 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 id applications related to this checklist. The area covered by the Comprehensive Water system Plan is basically the Renton City limits,with minor deviations for historical service outside the corporate limits(See Figure 3 of the plan). Service by the City beyond these areas is not currently contemplated for two reasons. First, areas outside the City's current service area are currently served by other purveyors. In most cases these purveyors receive their water from the City of Seattle. Seattle surface water is not compatible with Renton's groundwater. Therefore, integrating this water into the Renton system is not proposed. Second, two Coordinated Water System Plans have been prepared that specify the limits of Renton's Water service area. Expanding Renton's water service area would require amendments to those plans under RCW 70.116. If the City were to annex areas outside the current approved service area, in all likelihood water service would continue to be provided by the existing water district under the provisions of RCW 57.16. If the City were to annex a portion of a water district, that district would be required to have its comprehensive plan approved by the City. C - 3 APPENDIX C 1 TO BE COMPLETED BY APPLICANT B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other Topographically,Renton is composed of the relatively flat valleys of the Green and Cedar Rivers bounded by sharply rising hillsides rising to relatively flat plateaus on the west, east and southeast. b. What is the steepest slope on the site (approximate percent slope)? Within the planning area, there are numerous slopes of greater than 40%. 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 prime farmland. According to the Soil Conservation Service, four main soil types predominate in the City of Renton. These include the Alderwood Association, the Beausite- Alderwood Association,the Everett Association,and the Oridia-Seattle-Woodinville Association. Of these associations, the Oridia-Seattle-Woodinville are generally desirable farming soils and are found in the Green River Valley portion of the city. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Many portions of the hillsides bordering the valleys are steeply sloping, unconsolidated glacial deposits that are highly susceptible to sliding. These areas have been mapped by the City of Renton and are subject to regulation under Ordinance 4-31-35 (Green-Belt Regulations). e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Implementation of portions of the Comprehensive Water System Plan may require importing of fill. Fill would be used for two primary purposes: structural fill or aesthetics. In certain areas, the native soils may not be adequate for foundations or loading. In such cases, a limited amount of structural backfill may be imported from local gravel pits. Fill may also be required in some cases to construct berms or visual buffers around certain facilities. This fill would also be locally obtained. As predesign is developed for each project, approximate quantities of filling and grading would be estimated and discussed in separate environmental documents. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. C - 4 SEPA Checklist The majority of the projects included in the comprehensive plan would be constructed in road corridors. However, erosion could occur whenever soils are exposed to rainfall. All construction projects would be supervised by the Utilities Division to assure compliance with City erosion control requirements. Erosion control for each project would be subject to stormwater utility review. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Implementation of the plan would not change the amount of impervious surfaces in the City to a measurable degree. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Any construction would comply with the City's drainage and erosion control requirements. Individual projects would generate specific environmental documents to address earth impacts. 2. Air a. What types of emissions to the air would result from the proposal (i.e., dust, automobile odors,industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities, if known. Implementation of the plan should not result in any significant emissions or dust. Minor amounts of dust may be produced during construction of some of the proposed facilities. b. Are there any off-site sources of emissions or odor that may affect. your proposal? If so, generally describe. None known c. Proposed measures to reduce or control emissions or other impacts to air, if any: If necessary, watering exposed soils to control dust would occur. Individual - projects would generate specific environmental documents to address air impacts, if any. 3. Water a. Surface: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, C - 5 APPENDIX C lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river into which it flows. Yes.- The northwest boundary of the City is the shoreline of Lake Washington. Other rivers and streams include the Cedar River, the Green River, May Creek and Springbrook Creek. The Cedar River is tributary to Lake.Washington. The Green River is tributary to Puget Sound. May Creek flows into Lake Washington and Springbrook Creek into the Green River. 2) Will the project require any work over, in or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. • As shown in Figure 5 of the Comprehensive Plan, some of the proposed improvements would cross or be constructed near waterbodies. Shoreline Management Substantial Development Permits would be obtained when required. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. No filling or dredging of waterbodies or wetlands is anticipated. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities, if known. No surface water withdrawals or diversions are planned. 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. Some of the proposed improvements would occur within the limits of the 100-year floodplain. No change in floodplain capacity is expected. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No waste discharges are proposed in the plan. b. Ground 1) Will groundwater be withdrawn, or will water be discharged to groundwater? Give general description,purpose,and approximate quantities, if known. C - 6 SEPA Checklist The City of Renton is totally dependant on groundwater for its water supply. As the city grows, additional groundwater sources would be developed as described in the plan. Renton currently has water rights for about 14,000 gallons per minute (gpm) of water. Additional rights for about 9,000 gpm are being pursued as part of implementation of the comprehensive plan. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: domestic sewage; industrial, containing the following chemicals ....; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. No discharges are contemplated. c. Water Runoff (including storm water): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (including quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. In some cases, implementation of the plan would create additional impervious a surfaces that would create stormwater runoff. In those cases, the water would be retained and detained consistent with Renton stormwater control requirements. 2) Could waste materials enter ground or surface waters? If so, generally describe. No. d. Proposed measures to reduce or control surface ground,and runoff water impacts, if any. Minimum amounts of new impervious surfaces would be created. Any stormwater would be controlled consistent with City code. 4. Plants a. Check or circle types of vegetation found on the site: X deciduous tree: alder, maple, aspen, other X evergreen tree: fir, cedar, pine, other X shrubs X grass C - 7 APPENDIX C X pasture crop or grain X wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other X water plants: water lily, eelgrass, milfoil, other X other types of vegetation b. What kind and amount of vegetation will be removed or altered? The specific types and amounts of vegetation that may be disturbed cannot be predicted. Since most projects would be within right-of-ways and under streets, minimum amounts of disturbance are expected. c. Proposed landscaping,use of native plants,or other measures to preserve or enhance vegetation on the site, if any: Above-ground structures or facilities would be landscaped to be compatible with the surrounding character. d. List threatened or endangered species known to be on or near the site. None known. 5. Animals a. Circle any birds and animals which have been observed on or near the site or are known to be on or near the site: birds: hawk, heron, eagle, songbirds, other: woodpecker, wren, duck, Canadian goose, owl mammals: deer, bear, elk, beaver, other: raccoon, squirrel, weasel fish: bass, salmon, trout, herring, shellfish, other b. List any threatened or endangered species known to be on or near the site. None known. c. Is the site part of a migration route? If so, explain. Yes. The entire state of Washington is within the Pacific flyway. The Cedar and Green Rivers are also spawning routes for salmon and steelhead trout. C - 8 SEPA Checklist I d. Proposed measures to preserve or enhance wildlife, if any. No specific wildlife enhance measures are proposed, since the plan should not have any measurable impact on wildlife. 6. Energy and Natural Resources a. What kinds of energy (electric, natural gas, oil,wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. Significant amounts of electricity are used by the City to operate the pumps that move water around the water system. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally explain. Solar access would not be affected by the implementation of the plan. c. What kind of energy conservation features are included in the plans of this proposal? List otherproposed measures to reduce or control energy impacts, if any: The Water Shortage Response Plan and the Conservation Plan are specifically designed to conserve water resources and reduce usage during an emergency. —' 7. Environmental Health a. Are there any environmental health hazards,including exposure to toxic chemicals,risk of fire and explosion, spill,or hazardous waste,that could occur as a result of this proposal? If so, describe. The City both chlorinates and fluoridates its water supply. Improper handling of these chemicals could create hazardous situations for utility employees (see b.7.a.2). 1) Describe special emergency services that might be required. No special emergency services would be required as part of this plan. 2) Proposed measures to reduce or control environmental health hazards, if any: As part of the City's safety program and in compliance with OSHA regulations, elaborate procedures and controls are in place to prevent any exposure to potentially hazardous chemicals. C - 9 1 APPENDIX C b) Noise 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other)? Operation of the water system is not affected by noise. 2) What types of levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. Operation of water pumps creates noise. 3) Proposed measures to reduce or control noise impacts, if any: Well pump houses and system pump stations are sited and constructed to prevent noise from affecting people or activities. Individual projects would generate specific environmental documents to address noise impacts, if any. 8. Land and Shoreline Use a. What is the current use of the site and adjacent properties? The predominant land use in the City of Renton is single-family residential, comprising about 24% of the land. About 22% of the City is vacant land. Streets and freeways take up another 20%. The remaining areas are split between commercial, industrial and public facilities. b. Has the site been used for agriculture? If so, describe. Historically, farming had been a small part of the economic base of the City. c. Describe any structures on the.site. Individual structures should not be affected by implementation of the water plan.

SIGNATURE The above answers are true and complete to the best of my knowledge. I understand that the lead agency is relying on them to make its decision. Signature: FWV-V `� Date Submitted: /i 7/' Z— d. . NON-PROJECT SUPPLEMENT 1. How would the proposal be likely to increase discharge to o water: emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise? The proposal is a 50-year plan to provide better water service to the City. Therefore, it would not directly result in any discharge to water, or in the production, storage, or release of toxic or hazardous substances or noise. a. Proposed measures to avoid or reduce such increases are: Does not apply. I 2. How would the proposal be likely to affect plants, animals, fish, or marine life? C - 15 APPENDIX C 110 The Plan would not directly affect plants, animals, fish, or marine life. a. Proposed measures to protect or conserve plants, animals, fish or marine life are: Does not apply. 3. How would the proposal be likely to deplete energy or natural resources? The intent of the proposal is to provide better energy and natural resources use by rationally projecting the City's needs and how those needs will be met. a. Proposed measures to protect or conserve energy and natural resources are: See above. 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, floodplain, or prime farmlands? The City's comprehensive plan and land use plan were each closely reviewed to ensure that this Comprehensive Water System Plan would be compatible with environmentally sensitive areas. See also questions A.7 and B.8.1. above. a. Proposed measures to protect such resources or to avoid or reduce impacts are: See above. 5. How would the proposed likely to affect land and shoreline use, including whether it would allow or encourage land or shoreline uses, incompatible with existing plans? The plans identified in the response to Question #4 were also reviewed for compatibility with land and shoreline existing and proposed use. Please see Exhibit A (attached) which includes Pg. 3-155 to 3-162 of the Draft EIS for the City of Renton Land Use Element. a. Proposed measures to avoid or reduce shoreline and land use impacts are: Please see DEIS mitigation measures. • C - 16 SEPA Checklist 6. How would the proposal be likely to increase demands on transportation or public services and utilities? _. The Comprehensive Water System Plan would help accommodate the increased demand on water service that the City has been and is expecting to continue experiencing. a. Proposed measures to reduce or respond to such demand(s) --. are: See above. 7. Identify, if possible, whether the proposal may conflictwith local, state, or federal laws or requirements for the protection of the environment. This Plan is in accordance with all local, state, and Federal law and requirements for the protection of the environment. The "No Action Project Alternative" would result in: 1) the inability of the City to obtain State and grant funding by virtue of not having an approved Water Comprehensive Plan, 2) not being in compliance with the State Department of Health regulations which mandate and updated and approved Comprehensive Plan every five years, and 3) the inability for the City to proceed with implementing of projects necessary to continue to provide a safe, adequate, and reliable water system.

(Ord. 4184, 11-7-88) FULL WIDTH OF PROPERTY: All persons or local improvement districts desiring to extend water mains in'the City must extend the APPENDIX E DEFINITIONS Consumption The true volume of water used by the water system customers. The volume is measured at each customer's connection to the distribution system. Demand The quantity of water obtained from the water supply source over a period of time to meet the needs of domestic, commercial, industrial and public use, and also fire fighting water, system losses, and miscellaneous other water uses. Demands are normally discussed in terms of flow rate, such as million gallons per day(mgd) or gallons per minute (gpm). The flow rates can be described in terms of a volume of water delivered during a certain time period. Flow rates pertinent to the analysis and design of water systems are: • Average Daily Demand (ADD). The total amount of water delivered to the system in a year divided by the number of days in the year. This is further divided into average residential(ADDR),commercial(ADDC),industrial(ADDI),and unaccounted for(ADDN) demands. • Maximum Month Demand. The total amount of water delivered to the system during the month of maximum water use. • Peak Hour Demand. The amount of water delivered to the system in the hour of maximum use usually occurring during the maximum day. Equalizing Storage Equalizing storage provides the differencebetween the capacity of the sources of supply and the maximum demand rate(generally considered the highest use hour of the hottest day of the year). In water systems which service a large number of residences,the demand for water varies hourly and supply facilities are sized to meet the average rate of the maximum day demand. The maximum hour demand rate is typically about twice the average maximum day rate. If equalizing storage is not available to provide water during peak hours, the supply facilities and major pipelines would have to be sized for the maximum hour demands. However, during non- _ peak hours,much of the supply capacity would not be used. Instead,equalizing storage facilities are used to make up the difference between maximum hour and maximum day demand. The stored water is released when demand exceeds the supply,and replenished when the supply exceeds demand. In this way supply facilities and pipelines can be smaller than if equalizing storage is not available,and,therefore,lower costs for supply and pipeline facilities are obtained. Fire Flow The rate of flow of water required during fire fighting. Fire Storage Reservoir capacity required to meet fire flows. E - 1 APPENDIX E Head A measure of pressure or force by water. Head is measured in feet and can be converted to pounds per square inch (psi) by dividing feet by 2.31. Head Loss Pressure reduction resulting form pipeline wall friction, bends, physical restrictions, or obstructions. Hydraulic Elevation The height of a free water surface above a defined datum; the height above a datum to which water in a pressure pipeline would rise in a vertical open-end pipe. Emergency or Reserve Storage Reservoir capacity provided to meet emergencies such as failure of supply, pipeline, pump station, or power outages. Service (Pressure) Zone A water system subsection operating from one source at a common hydraulic elevation. Turbidity A measure of suspended particles in water. Unaccounted-for Water Water that is measured as going into the distribution system but not metered as going out of the system. Standby Storage Standby storage provides supply during fires, equipment failures, or power failures. Standby storage is seldom used, but obviously essential. The volume required for standby storage is determined based on the amount of water needed for fire-fighting reserves and other emergency conditions in the service area. The volume required for fire-fighting reserves is based on City Ordinance which uses the Insurance Service Office (ISO) fireflow requirements and is equal to the amount of water required to extinguish the largest probable fire in the service area. Standby storage for emergency conditions provides supply during equipment or pipeline failure and is based on the Department of Social and Health Services (DSHS) criteria of 800 gallons per customer, or on failure probability criteria. Since it is probable that a fire and equipment failure could occur simultaneously, the quantity of standby storage should be the sum of the fire-fighting reserves and emergency storage E - 2 Definitions 1 requirements. Furthermore, the fire-fighting reserves must be contained above the elevation that will produce a minimum of 20 psi pressure at the highest service in the zone, to allow the fire department to use the fireflow storage efficiently without cavitation in the distribution system pipelines or contamination in a customer's service.

The purpose of the Renton Comprehensive Water System Plan is to present a list of recommended facility improvements and policy criteria to be used to construct and maintain a potable municipal water supply system that is "adequate, safe and reliable". This plan is an update of the plan adopted in 1984, and complies with WAC 248-54-580. This plan is based on current City policy, regulations and laws adopted by Federal and State government and the Renton City Council.This chapter is a summary of the issues and policies discussed in the remainder of the Plan. PLANNING The City's service area population and land use trends are major factors affecting water system planning.The service area boundaries have been established through agreements with adjacent purveyors using the Skyway Coordinated Water System Plan and The East King County Coordinated Water System Plan as the planning vehicles. Renton is required to use these plans as the basis for service area boundaries by State law. The service area boundaries will not change without annexation. Any areas that are annexed will likely contain water service areas that do not meet Renton's standards for water supply and reliability. In addition Renton may or may not have adequate supplies to service annexed areas, and therefore annexation must be closely coordinated with the water utility. The City is currently in the process of redefining land use and adopting policies that are consistent with the Growth Management Act. The Growth Management Act will impact the Water Utility. It will require closer coordination with the Planning Department, it will require the development of additional water supplies, it will require the addition of pump stations, reservoirs and pipelines, and will make development of these facilities more costly. The Water Utility will require more staff to comply with these additional requirements. Water Rights are becoming more difficult to obtain and are now a major component of water system planning. Because of the length of time required to obtain water rights, water supplies that will not be needed for many years must be pursued now. It is probable that sometime in the future Renton will not be able to obtain additional water rights and must then either limit growth, reduce water supply standards, or purchase water from a regional water supply • organization. Any of these events would require significant changes in Renton's water policies. The lengthy and complicated water rights process will increase facility costs. Renton's service area has been included in the East King County Regional Water Supply Plan, and Renton has been asked to participate in developing regional water supply sources. These sources may not benefit Renton's water supply system, and will be more costly to develop than Renton's own groundwater supply system. Renton has developed a long range water supply plan that compares the cost of various supply alternatives and the feasibility of maintaining cost and quality controls on the alternatives. Renton should continue to pursue their own City located groundwater supplies. Table 8-3 from chapter 8 shows the anticipated growth in the water system over the next 50 year period, and 1 - 1 REN\WCP\WCPCHAPI CHAPTER ONE also shows the supply sources that must be developed to meet the anticipated demand growth. The table is repeated in this executive summary for reference. Most of Renton's neighbors are experiencing reductions in water supply. Conservation is being used aggressively in these areas in an attempt to extend the capabilities of their existing water supply systems. Renton is not experiencing this water supply crisis but will be required to implement the same water conservation activities. Recent water quality legislation may require Renton to construct and operate a water treatment plant or plants, that treats all of the City's water. This may be required even though the water is high quality and meets the regulatory standards. Some treatment is required now to reduce the corrosivity of the water and prevent heavy metals in the water system. Any water treatment is expensive and will raise the cost of water supply. Population projections have a large impact on water supply planning, however, proposed land use changes in the service area have a small impact. Water supply is more directly affected by the number of people served than by the type of land use that is served. Fire flow requirements and landscape irrigation have the largest impact on water system facilities. Renton is a recognized regional leader in water policy and the application of technology to reduce water rates and improve water quality. As a result many new technologies are invented in Renton and many regulatory policies and standards are tested and refined here. Renton is therefore a frequent recipient of grant funding, and a respected participant in State and Federal Government activities. These policies should be continued since they often result in standards and requirements that are favorable for Renton's water customers. Water quality and supply reliability and redundancy standards and policies have the largest impact on water supply costs,and facility planning and phasing. In fact,water resource planning and water quality (aquifer) protection are the utilities highest priorities. EXISTING SYSTEM The existing water system is very well maintained and provides a high level of service. The system is deficient however in booster station capacity to the Highlands 435 and 565 pressure zones, and the West Hill pressure zones, and is deficient in reservoir storage capacity in most pressure zones. These deficiencies have not presented past problems because the system is well maintained and experiences fewer than normal failures. They will be resolved however using a phased construction schedule and capital improvement program.Highest priority has been given to facilities that will accommodate growth and resolve these system deficiencies. Water quality is high, however the system is vulnerable to groundwater contaminations. The City is aggressively pursuing policies and procedures that will maximize the integrity of the water supply system, and provide redundancy in the event of a contamination of any single aquifer. The water distribution system has been designed to provide maximum day demands and simultaneous fire flows to all customers. 1 - 2 REN\WCP\WCPCHAP1 Executive Summary A program is currently underway to replace the City's aging steel and AC watermains using a phased replacement schedule. Facilities are replaced or upgraded as needed to comply with regulatory changes and as components wear out. FUTURE SYSTEM The City has an adequate source of potable groundwater resources located within the existing service area. Competing uses for these supplies has made their development more difficult. Development of additional groundwater supplies should be pursued as aggressively as possible, since it is assumed that political and or economic events will make future development impossible. The City should not compromise their quality or quantity standards because of regional supply inadequacies, and therefore should not depend on the development of regional supply sources for the future needs of the City. Water conservation is currently being used in lieu of developing additional water supplies by Renton's neighbors. Water reuse will inevitably be an attractive alternative to water conservation. The regions largest potential source of reused water(the METRO treatment plant) is located within Renton's service area. Renton will pursue the adoption of reuse standards to capitalize on this potentially valuable resource. Renton will supply all customers located within the service area boundaries and will control and administer all municipal services within the service area, including reused water. IMPROVEMENTS The City will prepare for and authorize a 20 year CIP budget to perform the work listed in the Capital Improvement Plan. The improvements anticipated within the next 20 years include: 12,750 gpm of additional well capacity 27,000 gpm of additional booster station capacity 26 million gallons of additional storage capacity Additional unspecified improvements include studies to assure future water supply, studies to anticipate treatment requirements, studies to minimize operating costs, and the construction of watermains to serve new customers and provide adequate fire protection to existing customers. The capital improvements and stricter regulatory standards will raise Renton's water rates. 1 - 3 REN\WCP\WCPCHAP1 • TABLE 8-3 ANTICIPATED SYSTEM GROWTH BY YEAR . 50 , , • , , . . • , , . --[-L--, LI -----Li---, -- --1_-----H-----1-L---1- -- --i- - - TI -r-17-11--- --'-1 Im -1-- _----,- --,-------1--- -1---- - - --1 r • 45 --7-- 7,--- I j 1 1. 1 , - -----r------r------I- —M T 1_ _i___ ,_. _i + L I I _LLL _LI 1 1 L I __t ____I 1 L._ ' _ ___1__ _---1- -----1---------,- --- -4- 4- 40 t I ,---- 1 1711-:---Hio -- Lg wt . , , .:„:,.,,, 1 L iii_ .

This plan is the result of a study which evaluated the existing water system and developed alternatives for operation and accommodating growth. The improvements identified in this plan are based on the requirements of the Washington State Department of Health (DOH) and City of Renton Policy. The City of Renton adopted its last comprehensive water system plan in 1984. That plan anticipated growth in the system and proposed improvements but did not foresee all issues which have arisen since that time: changes in water resource allocation, changes in water quality standards, significant increases in construction cost, land use densities, and population projections. These issues and others are examined in detail in this Comprehensive Plan. The Renton water system is large and, because of the topography, it is difficult to understand and operate. The condition of the current system, as well as the need for improvements in a level of detail that will satisfy most readers, has been documented. However, due to the magnitude of this system and the number of issues that must be addressed, this report is organized so that a reader may review a summaryof the plan in Chapter 1, without reading the background or detailed information which led to those results. Readers interested in more details should examine the remainder of the report. The plan provides a recognized framework for making decisions about potable water supply in the City of Renton. It is intended to aid users including the Water Utility, City Council members, the Mayor and staff, builders, developers, community groups, and other government agencies. The plan helps these users in several ways. First, the plan is the framework for improvements and operations that govern water system developments in the,City's service area. The plan provides a basis for allocating improvements and costs to new, additional water users in the system, such as home and apartment builders and commercial developers. It thus provides,City officials with partial direction for approving building permits and upgrading the system. Second, the plan provides a guideline for improving the existing system to supply each customer with adequate supply and acceptable quality water. It is intended that City officials will be able to use these guidelines as supply and quality standards change, to maintain the highest quality service at the least cost. Finally, the plan provides a basis for accommodating changes that occur but that cannot be forecast in the plan. To this end, the plan lists policy issues and operational criteria that can be used to develop alternatives and direction for development, improvements, and operations. 2 - 1 REN\WCP\WCPCHAP2 CHAPTER TWO Several members of the City staff possess an exceptionally detailed understanding of the City's water system, and have provided valuable input for this plan. Mr. Ron Olsen, Mrs. Arlene Haight, Mr. Ray Sled and Mr. Jack Crumley are thanked for their assistance. HOW TO USE THIS PLAN This plan is arranged in eight major sections. Chapter 3 identifies the existing facilities, and documents the history of the water utility. Chapter 4 documents the condition of the existing facilities, discusses land use and adjacent systems. Chapter 5 examines demands for existing conditions as well as anticipated future conditions. Chapter 6 documents current and planned water supplies to meet the demands listed in Chapter 5. Chapter 7 identifies the policies and design criteria for the water utility. Chapter 8 examines the condition and performance of the existing system in accordance with the accepted policies and criteria through system analysis. Chapter 9 identifies improvements necessary to comply with policy requirements, law, and anticipated future conditions. Chapters 10 and 11 examine the operations, maintenance and financial characteristics of the utility. • I 2 - 2 REN\WCP\WCPCHAP2 Water Resources The City will be required to begin monitoring in July of 1992 at approximately 40 sampling sites every 6 months. Radionuclides Rule The EPA is currently developing new regulations for monitoring of radium 226 and 228, uranium, and radon (radionuclides). Proposed MCLs are 300p CV! for radon and 20p CO for uranium and radium.226 and 228. The final rule is due March 1992. Monitoring for radionuclides is to be scheduled on a nine-year compliance cycle divided into three-year compliance periods, with the first period beginning January 1, 1993. During each three-year compliance period, systems will monitor radionuclides at the time specified by the State or other primary agency. The number of samples will vary depending on how the distribution system is supplied;i.e.,by several groundwater and/or surface water sources. Water systems should analyze for the radionuclides covered by the rule and determine whether changes in treatment practices will be necessary, and if so, estimate the cost of treatment. An article describing the new radionuclide regulation was published in the AWWA Journal, April 1991. The Wellhead Protection Program The amendments to the SDWA require states to develop a Wellhead Protection Program and submit it to the EPA for review and approval by June 19, 1989. The underlying purpose of the program into protect public water supply wells from sources of contamination. To date, only six of thirty states that have submitted their Wellhead Protection Programs have had their submittals approved by the EPA. Washington has not submitted a Wellhead Protection Program. SWDA's Impact on the City Since groundwater supplies City customers,Renton will primarily be concerned with compliance with the Total Coliform Rule, the Lead and Copper Rule, and Radionuclides Rule (radon removal). Exotic organic and inorganic contaminants,which require significantly more expensive treatment technologies, rarely occur in public water supplies at levels above proposed MCLs. The City has already developed an aquifer protection plan in an effort to avoid disinfection. A study is currently underway by EES To identify the specific impacts of the new water quality laws. The water quality study should continue as needed until all standards and requirements have been satisfied. It is widely accepted that all municipal water supply systems will eventually need to filter and treat all potable water supplied to the public. If this is true, Renton will eventually need to construct a water treatment plant near the existing Cedar River well field. The Utility Department should pursue the acquisition of a treatment plant site for future use. 7. Long Range Water Supply Planning Renton is a leader in water supply planning. To protect the quality of its water,it has developed an extensive wellhead protection program. To assure an adequate supply, it has developed its own groundwater resource and entered into agreements with adjacent purveyors. 6 - 21 REN\WCP\WCPCRAP6 CHAPTER SIX The City's water system now faces the challenge of serving a growing population. The recent rehabilitation of Well 5, and the construction-in-progress of Wells'11 and 17 in the Maplewood Golf Course, will provide adequate supply to meet demands through 1995. Long Range Supply Planning must begin now however, because acquiring additional water supply has become a complex and lengthy process. Continuing regional growth places more demands on a fixed amount of water, which is subject to more stringent regulations and to a more complicated planning process. Federal and State Water Laws Water is increasingly regulated on federal and state levels. These regulations that will have an impact on the City of Renton's water supply planning. Safe Drinking Water Act. Sixty-two of the eighty-two 1986 amendments to the Safe Drinking Water Act have been written. The new rules will require the City to begin a variety of monitoring and treatment programs. Overlapping roles of the Department of Health (DOH) and the Department of Ecology (Ecology). DOH and Ecology share the responsibility for managing water resources. DOH's role of overseeing water utilities, and Ecology's role of overseeing water resource management,often overlap, causing delays in approving water plans and allocating water rights. Growth Management Act (GMA). The GMA required coordination of land use and water supply planning to ensure 1)concurrency,2)that designated urban growth areas were providing urban levels of water service, and 3).critical areas such as aquifers were protected. Chelan Agreement.The Chelan agreement is the consensus reached by eight different interest groups on how to regionally plan for water. Two pilot planning projects are currently underway. Ecology is hoping to draft new water resources policy based on their results. Regional Water Supply Options The City of Renton has examined the options for regional water supplies that have been proposed as a result of regional or local planning. This plan evaluated the most recent feasible proposals of the following utilities or utility groups: the Seattle Water Department (SWD), the East King County Coordinated Water System Plan (EKCCWSP), the East King County Regional Water Association (RWA), and the City of Tacoma Water Division. Seattle Water Department. The SWD is considering four regional water supply projects, which are: • Pumping unused or "dead" storage from Chester Morse Lake, which is one of Seattle's two major surface water sources, providing approximately two-thirds of the total supply. • Diverting flows from the North Fork into the South Fork of the Tolt River, which is Seattle's second major surface water source, providing approximately one-third of the total supply. ' 6 - 22 REN\WcP\WCPCHAP6 Water Resources • Diverting flows from the Skagit River to the Tolt pipeline near Woodinville. • Discharging treated METRO effluent into Lake Washington and diverting additional flows from the Cedar which are normally discharged into Lake Washington. East King County Coordinated Water System Plan. The EKCCWSP regional water supply proposals generally parallel Seattle's proposals. However,it did include a proposal for an intertie between the City of Everett's water system to utilities in East King County: • Additional flows would be released from Spada Lake, a storage Reservoir for the Sultan River, Everett's primary source of supply. The water would be conveyed through a transmission pipeline from South Snohomish to the Tolt pipeline near Woodinville. East King County RWA. Most of the water systems represented by the RWA are supplied by Seattle,which has indicated it will not have sufficient capacity to serve them beyond 1994. The City of North Bend, a member of the RWA,invited other RWA members to explore the possibility of a regional groundwater supply in the Upper Snoqualamie Valley. The valley has the geologic deposits and the hydrologic conditions that are favorable for the groundwater storage. The project would provide water supply by: • Developing 16 groundwater wells and a transmission pipeline to the Tolt Eastside Supply Line. City of Tacoma Water Division. The City of Tacoma currently obtains part of its water from the Green River downstream of the Howard Hansen Reservoir. Pipeline No. 5 would convey more of this water downstream of the reservoir into the City of Tacoma. • Pipeline 5 could supply South King County through a pipeline that would extend north. City of Renton Source of Supply Options Currently,the City's maximum day demand exceeds the supply capacity as shown in Table 8.3, Projected Water System Growth. Water demand will continue to increase as.the City's population grows. In response, the City rehabilitated one well and developed two others on the Maplewood Wellfield. If no other supply sources are developed, the additional supply from the three wells will adequately meet demands until 1995, when demand will equal supply. The Maplewood Booster Station is being designed to handle a supply that is greater than the supply from Wells 11 & 17. Developing the wellfield will provide water supply to accommodate additional growth. The improvements described below are those that are necessary to meet the maximum design capacity of the booster station. The wellfield taps into two aquifers, a middle aquifer and deeper aquifer. The wellfield developments described below.would all tap into the middle aquifer: • • Drill Production Well No. 11 (completed 1988) 6 - 23 REN\WCP\WCPCHAPG CHAPTER SIX • Drill Production Well No. 17 (completed 1989) • Construct Wellheads for PW - 11 and 17 (Completed 1991) • Construct Maplewood Booster Station and Treatment Facility (Scheduled 1992) • Drill Production Well No. 10 (Scheduled 1992) • Drill Production Well No. 12 (Scheduled 1992) • Construct Highlands Water Transmission Pipeline (Scheduled 1992) • Construct Rolling Hills Water Transmission Pipeline (Scheduled 1992) Development of the deep aquifer is still in the exploratory phase. At this time, three production wells are planned for this area. Evaluation of Regional Water Supply Alternatives The City has prepared a separate Long Range Water Supply document that evaluates the costs and impacts of the regional supply options. The results of the analysis are detailed below: • Morse Lake Pumping. The cost per yield is comparatively low,but that does not outweigh the risk for depleting the "dead storage" to a level that could not be replenished during a relatively dry winter, making it impossible to meet the demands the next summer.. In addition, lowering the.lake level may damage the sensitive bottom clay, causing leakage from the lake. Water rights, instream flows, and treaty rights must also be resolved. • Tolt Diversion This project may increase instream flows in the South Fork and improve reliability of Tolt supply system. In addition, Ecology is offering SWD a water right on the South Fork, for which a treatment plant design is currently underway. However, SWD does not have a water right to withdraw from the North Fork. Treaty rights must also be resolved. • Skagit River.Pipeline Diversion. It would provide more supply than other options, but the actual yield is unknown. The size and remote location of this project make it expensive and involve many political issues which will complicate and prolong planning and design efforts. • METRO Effluent. Its comparatively high cost and its impact on Lake Washington's water quality make it an unlikely source of potable water. However, treated effluent could possibly be used for irrigation and industrial uses. • North Bend Groundwater. It would provide the lowest cost per yield of the regional alternatives, would not require treatment, and would serve the Sammamish Plateau, an area not yet served by a regional water system. However, the amount of water is not yet proven and water rights acquisitions and pipeline construction would raise issues that must be resolved. • Sultan River/Everett Intertie. It would serve a broad area and its cost per yield would be average. However, Everett and the Snohomish County PUD are offering it only under the condition that it would be returned when their demand increases. 6 - 24 REN\WCP\WCPCHAPG Water Resources • Tacoma Pipeline 5. The City of Tacoma is aggressively pursuing this project, but a range of issues, including instream flows, wetlands, and Treaty rights, makes this probability of this occurring unknown. Recommendation The Maplewood Wellfield is the clear choice of all the options. The City.of Renton has succeeded in providing an adequate quantity and quality of water to its citizens by developing its own water resources for many years. Developing the Maplewood Wellfield has a lower cost per yield than the regional alternatives, and is the most likely to be implemented for political, environmental, and economic reasons (as discussed below). • Economic Basis. Continuing to develop additional sources of supply in the Maplewood Golf Course area would be substantially less expensive than obtaining water from a regional water supplier. • Environmental Basis. Renton will continue to grow in the 1990s. As its urban density increases it will be imperative to regulate the land uses within the aquifer's recharge area. This can best be accomplished if the City develops its own wells. Coordinating land use and water supply planning will be in compliance with the Growth Management Act. • Political Basis. By maintaining its independence, the City could avoid an overly lengthy planning process. However, properly managing the resource may benefit other water utilities within the region. Specifically, obtaining accurate instream flow and hydraulic continuity data for the Cedar River would allow the City to seasonally manage recharge to the river. By recharging the river, all water users demands would be met, avoiding lengthy water rights conflicts. By planning and managing the water resource with other users in the region, the City would be at the front of a clear trend in state public policy of managing natural resources regionally. 6 - 25 REN\WCP\WCPCHAP6 1 Appendix F WATER MAIN REPLACEMENT PRIORITIZATION APPENDIX F Water Main Replacement Prioritization F - 1 REN\WCP\APP-F.WCP 111 • • APPENDIX F :gM .............F.N.:::.........::•.:9g:::::::::isz::�:;�::;�:;:�;>s::�;:�:�;s:z:::rr:i;:�::�::sR�:;:�;'> ::;::�;:�;s:�;:�iisi::;: ��A�: Uisi.Rlott'pn)fNG'E• LJND, • WA.t>:>:;::: :..:.►..�MR�::;;;.�: Revision Date: 2/24/92 ...�...,: .. :; . �. wA:.. ,; I :.: :: ;;::;ti,; , ;. ,.;;,;,,;,;;.;;.,A3,,,,,,;•,;;,•,,This Consilium listing does not reflect all of the undersized A) Contininuing of project under construction 3 C.I., STL., and A.C. serviced in the City of Renton.
