Chapter One EXECUTIVE SUMMARY 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. 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 vehicle. Servic.a 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. 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 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 C/P budget of$65,000,000.00. Improvements include: 12,750 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 Chapter Two INTRODUCTION :.- . 1-4-,-,,,,- „•-.-, 104i1 . 1..' , $ Litt PIN .. ,., ,......_....„ . . .'",' ...5°'''' .. ........ 200 I. i ,,.. vaMillIOP , ' •Ii..,....-;,,..-... •: : 1 : '.,;...

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 and City 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 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 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 . �Milli' . .„i.; + , . �. X11111111 .

SYSTEM OVERVIEW The City of Renton's Water System provides service to an area of approximately 60 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 6 wells and one artesian spring that are used for normal supply, and 5 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 boostor 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 fire flow 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 to a higher zone where it is used primarily to 3-1 supply residential and commercial demands. In the City's system, water moves up through the pump station 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 isvulnerable 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. STORAGE Construction of the 1.4 million gallon (MG) West Hill Reservoir. Construction of the 1.5 million gallon (MG) South Talbot Hill Reservoir. 3-2 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 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 Goff Course. Construction of the Oaksdale Transmission Pipeline. Construction of the 24-inch Transmission Pipeline from Wells 1, 2 and 3 to South 4th Street. 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. 3-3 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 pressure zone provides. 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. 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. Itis 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. 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 PRV's from an upper zone, would be 3-4 TABLE 3-1 PRESSURE ZONES Maximum Minimum Minimum Maximum Elevation Service Elevation Service Served Pressure Served Pressure Pressure Zone (feet) fail (feet) 1.012 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. cominbed 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/Talbot Hill Rolling Hills 590 Zone Rolling Hills 490 Zone k Talbot Hill 350 Zone Talbot Hill 300 Zone Renton Hill 370 Zone Renton Hill 490 Zone 3-5 At saturation ft 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. • 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 2400 gpm, however, the wells are throttled to 2200 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 inch 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 corner of 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 1500 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. 3-6 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-inch diameter discharge pipe for the well extends east and connects into the 24-inch diameter transmission pipeline. The flow meter is located outside the pump facility in a buried, rectangular concrete vault. • Well Facility No. 9 (P W9) The well facility,constructed in 1986, is an above grade structure constructed from architectural brick and a preformed 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, therefore, 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 1250 gpm. The 12 inch diameter discharge pipe for the well extends south and connects to a 24-inch diameter transmission pipeline. The flow meter is located outside the pump facility in a buried concrete vault. • Springbrook Springs The Spring facility was originally constructed in 1909 and the latest rehabilitation was completed in 1976. The Spring 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 Spring. 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 ;n 1987, is located approximately 300 yards from the infiltration galleries adjacent to the transmission pipeline. The Spring 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 Spring. The Spring facility is a free flowing facility with no control of its discharge rate. In its past, the Spring has had a capacity of near 1200 gpm;however,recently the supply rate has 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. Itis possible that a rehabilitation of the springs will increase the production to the water right capacity. • 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 1960's 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 raised, 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 3-7 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. • 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 1500 gpm for Well No. 17. Design of the well pumping and treatment facilities is currently underway. TABLE 3-4 is a summary of existing supply from the wells and Springbrook Springs. 5. 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 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 No's. 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 DOH standards. The chlorine storage and feed rooms at Well No's Ri,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 part par million 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 6 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 1 month of supply. A storage and separate feed room are located in the well building at Well No's. 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. 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 hazard material disposal site. The fluoride day tanks are alarmed for a low level conditions, and a spare chemical metering pump is provided at each site. 3-8 i r EXISTING ON-LINE SUPPLY TABLE 3-4 3500--V _ ` •?><=t Nig o:aC /4•1•'.$‘6'•-•...,'c'','7--- ..-'::`:‘•':.K.''''. -A''':-z• Y,.ZU:.*C:t:tiY;r+' • i:F:`vi.?i ''ti�!

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, 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 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 H111495 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-inch 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 PRV's from the upper 490 and 590 pressure zones. 3-10 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-inch 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-inch 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 inches in diameter that convey water from the transmission grid to the individual service connections. A distribution system functions by meeting individual demands in the immediate vicinity via branching and looping pipelines through the service area. TABLE 3-2 and TABLE 3-3 summarizes pipe lengths by size in the water system. 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 TABLE 3-2 PIPE INVENTORY BY PRESSURE ZONE ROLLING 435/ WEST /TALBOT 196 320 565 HiLL HILL PiPE ZONE ZONE ZONE ZONE ZONE TOTAL SIZE (FEET) (FEET) (FEET) (FEET) (FEET) (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 3-11 / WATER MAIN DISTRIBUTION BY PIPE SIZE TABLE 3-3 250-7 ,,:>,:.•y :::4 t iii.:*, : 't—I.. .ls�,i 0: E 150f 1 r Z r , J C ;gy., ,..

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 4 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 to upper pressure zones. All supply to the upper pressure zones is provided by booster pump stations. Fire flow requirements are met using a combination of supply from booster stations and storage in upper zones rather than 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 N.E.) 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 Blvd N.E.) 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 N.E.) 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 3-13 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. Although the site is not fenced, no vandalism has been noted at this station. Highlands Pump Station(3410 N.E. 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 fire flow 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 S.E.) 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 and 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. 3-14 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 fire flow 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 PRV's should be located hydraulically remote from both upper and lower zone reservoirs to promote good circulation in both zones and maintain water quality. Lag PRV's may be located hydraulically closer to storage to minimize System head losses during high flow rate conditions when the lag valves need to operate. The primary purposes of the PRV's 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. 3-15 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 1050 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-inch 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-inch pressure reducing station,and one 6-inch 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. TABLE 3-5 lists supply rates available from the standby facilities. 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, and others do not. In-service interties with agreements are maintained with the City's 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 fire flow 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 3-6 lists supply rates available from emergency facilities. TABLE 3-7 and TABLE 3-8 are summaries of on-line supply,standby supply, and emergency supply for the water system. 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. 3-16 _ / / .

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.i 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 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. 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. 3-21 Improvements Since 1983 All of the control equipment in the system-has beenreplaced 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 system proposed,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. 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. Phase Nos. 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. 3-22 Chapter Four LAND USE AND ADJACENT SYSTEMS It wrqi it! , stif...iiididiiiiki .....iiii,...., _ ,- _ --',"-gar .. .11100....-- �. .- , ."" ,t 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 3 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 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 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 it. • Virtually all of the different types of geological deposits and stratas, as a result of glacial recession 4-1 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 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. 4-2 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 Land Use Plans adopted for each Planning Area Planned land use in the service area is based on current City policy. Section 3 A 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 development of outlying areas. This policy section provides the framework for current land use development and is stated below. 3A LAND DEVELOPMENT OBJECflVE: 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 l 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. 4-3 Based on these policy statements, the objectives of the Comprehensive Land Use Plan updates are as follows: 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 pcpulation 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 4-4 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. 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 isi shown in TABLE 4-1. Unusable acres include areas too steep to develop, or areas that are occupied by rivers or wetlands. 3. ADJACENT SYSTEMS The Renton Water System is surrounded by tent 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 futuIre 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. 4-5 • TABLE 4-1 SATURATION LAND USE PROJECTIONS TOTAL EXIST UN- UN- AREA AREA DEVEL USEABLE DEVEL AVAIL (ACRES) (ACRES) (ACRES) (ACRES) (ACRES) DOWNTOWN 196 ZONE SINGLE FAMILY 280 266 5 14 9 MULTI-FAMILY 696 226 12 470 458 COMMERCIAL 1,947 1,579 0 368 368 PUBLIC 799 684 0 115 115 SUBTOTAL 3,722 2,755 17 967 950 HIGHLANDS 435/KENNYDALE 320 SINGLE FAMILY 813 424 183 389 206 MULTI-FAMILY 304 35 4 269 265 COMMERCIAL 255 26 0 229 229 PUBLIC 361 221 25 140 115 SUBTOTAL 1,733 706 212 1,027 815 HIGHLANDS 565 ZONE SINGLE FAMILY 1,480 482 371 998 627 .

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 Goff 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 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 servo 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 they 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 ofd 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 Renton and Kent, 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. • 4-7 The 1982 Plan Amendment presented a significantly reduced maximum day demand of 22 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 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. ft 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 fireflows. 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 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 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, Eariington, 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 District's 63 and 14)is suppled 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 they Skyway Coordinated Water System Plan prepared in 1989 by Horton Dennis 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 East King County Coordinated Water System Plan 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 approv,al phase,a process which is expected to be completed in 1990. The plan includes several recommendations for constructing water supply system improvements, andfor the administration of 4-9 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 served by the City of Seattle, or experiencing supply inadequacies. Renton is in a unique position in regard to the development and implementation of this program. 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 East King County Coordinated Water System Plan 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 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 plans 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 cfs/3.2 MGD or more in accordance with RCW 90.54.050(2)until July 1, 1994, or until the State reserves 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 Ill of Tolt Pipeline No.2 in the SWD capital improvement program for completion by June, 1992. 4-10 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 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: • 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 4-11 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. 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(than 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. • 4-12 Chapter Five DEMANDS • 4ae . F • B , •. [9 906 Chapter Five DEMANDS 1. WATER USE CLASSIFICATION The City of Renton's water users 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 ERU's. 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 ERU's. For saturation planning,each undeveloped acre is assumed to equal 13 ERU's. 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 meter size was larger than 1". The larger,metered customers were individually evaluated,and their specific water use habits were assigned an appropriate number of ERU's, 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 ERU's. 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. A summary of equivalent development by Planning area is shown in TABLE 5-1. Currently,Renton sells water to Lakeridge Bryn-Mawr Water and Sewer District on a wholesale rate basis. 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) 5-1 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 5-15 shows a summary of system demand for the past five year period. 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 which 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 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 ERU's per unit. Large and industrial users are converted to ERU's by individually examining water use history. The number of ERU's 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 5-2 TABLE 5-1 EQUIVALENT DEVELOPMENT BY PLANNING AREA ERU PER 1987 AREA 1987 SATURATION SATURATION 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 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 HIGHLANDS 565 SINGLE-FAMILY 6 482 2,892 1,109 6,654 MULTI-FAMILY 13 21 273 211 2,743 COMMERCIAL 5.3 49 260 229 1,214 PUBLIC 1 387 387 845 845 SUBTOTAL 939 3,812 2,394 11,456 ROLLING/TALBOT HILLS ZONE SINGLE-FAMILY 6 264 1,584 654 3,924 MULTI-FAMILY 13 36 468 182 2,366 COMMERCIAL 5.3 1 5 3 16 PUBLIC 1 250 250 424 424 SUBTOTAL 551 2,307 1,263 6,730 WESTHILL ZONES SINGLE-FAMILY 6 336 2,016 336 2,016 MULTI-FAMILY 13 15 195 33 429 COMMERCIAL 5.3 23 ' 122 31 164 PUBLIC 1 34 34 57 57 SUBTOTAL 408 2,367 457 2,666 TOTAL 5,359 25,430 9,340 51,880 *FROM TABLE 4-1 (TOTAL AREA-UNUSABLE AREA) 5-3 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 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%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 5-2 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 5-2 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. TABLE 5-3 shows the ratio of maximum day and peak hour demands to average day demand. TABLE 5-4 is a summary of minimum and maximum day demand both at existing and saturation conditions,by pressure zone. TABLE 5-5 shows the distribution of demand between the various customer classes within each pressure zone. TABLE 5-6 shows the distribution of developable area in the water system by Equivalent Residential Unit for current and saturation demand conditions. The distribution by pressure zone is shown as a percentage of the total system demand. TABLE 5-7 shows the same information, but uses developable acreage instead of ERU. TABLES 5-8 through 5-12 shows the distribution of water demand by customer classification for each operating area both at current demand and saturation demand condition. The demand is distributed as a percentage of the demand for each operating area. TABLE 5-13 shows the relationship between average day, maximum day, and maximum hour demands by operating area, at current demand conditions. TABLE 5-14 shows the same information at saturation development. On a system-wide basis, the ratio of demand to average annual daily demand is as follows: TABLE 5-3 DEMAND RATIOS Average daily demand 1.0: 1.0 Maximum day demand 1.0: 2.54 Peak hour demand 1.0: 3.63 TABLE 5-15 shows average day demand for the past 5 years. 4. 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. 5-4 PROJECTED WATER SYSTEM GROWTH TABLE 5-2 30— 28— 28— 24— F-. g � 22-- O i 20- 18- 18- 14 1*:71J89I 11911 113' 1995 1997 1J991 20011 26'2h05t 261 2 91 ZO1 i 12b13'2b15I 2117 2b19'20211 2b23I 265'2J271 269'2&311233312351 2037 An"1 I 1988 1990 1992 1994 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 2016 2018 2020 2022 2024 2026 2028 2030 2032 2034 2036 2038 2040 YEAR TABLE 5-4 DEMAND SUMMARY 1987 MIN 1987 MAX SAT.

DEMAND COMPONENTS Total System demand can be divided into three major components which consist of: • Residential Demands(Single and Multiple Family Services) • Commercial-Industrial, Public Facilities and Other Use Demands • System Losses (unaccounted for water) TABLE 5-5 DEMANDS BY PLANNING AREA 1987 MAX DAY SATURATION DEMAND MAX DAY DEMAND (GPM) (GPM) Downtown 196 Zone Single family 886 917 Multi-family 1,634 4,942 Commercial 4,648 5,733 Public 380 444 SUBTOTAL 7,548 12,036 Highlands 435/Kennydale 320 Single family 1,412 2,099 Mulct-family 257 2,164 Commercial 76 750 Public 123 187 SUBTOTAL 1,868 5,200 Highlands 565 Zone Single family 1,605 3,698 Multi-family 155 1,527 Commercial 143 675 Public 215 470 SUBTOTAL 2,118 6,370 Rolling/Talbot Hill Zones Single family 880 2,180 Multi-family 260 1,314 Commercial 2 8 Public 139 236 SUBTOTAL 1,281 3,738 West Hill Zones Single family 1,121 1,012 Multi-family 111 241 5-7 These three components (growth, weather, conservation) are comprised of both peaking or 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 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 per service 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 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 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 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 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, ISO recommends that the following standards be met in conjunction with the recommended fireflow demand: 5-8 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. 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. r _ 5-9 SYSTEM DEVELOPMENT DISTRIBUTION BY EQUIVALENT RESIDENTIAL UNIT TABLE 5-6 WEST HILL ZONES(236 A N ROLLING/TALBOT HILL ZONES(2307) \ Y : , HIGHLANDS 565(3812 ,•^::.*::v:rnv=.:rv.,f� , ,� DOWNTOWN 196 ZONE 1358 4r• f] t•. ,c} ,• ys f; xG..c2r b•♦ g i HIGHLANDS 435/14ENNYDALE 320(3358 ...,...,...„:4:::;:::::k..4: .., wfi K y Y} :.,' :. 1987 WEST HILL ZONES(2666.

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 area and the West Hill area 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 addittional 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. 5-1 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. Groundwater contamination would directly and immediately effect 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 from a gasoline station leak, the City adopted an underground storage tank ordinance, Resolution No. 414Z 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 the aquifer, however, are not yet completely understood, although it is assumed that additional testing and modelling can provide an accurate contaminant transport model. 6-2 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. in recent years, the State of Washington has enacted several statutes which were directed toward the protection of groundwater. The Washington Department of Ecology has the primary responsibility for coordinating groundwater protection efforts and overseeing the development of groundwater management plans. The Washington Department of 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,the Department of 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 eduction. Several State statutes and its protection from contamination. TABLE 6-2 is a brief description of the most significant State statutes. 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 which 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. Contamination Sources It is important to recognize that ground water contamination can occur from several sources,several 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, storm water 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. .. 6-3 TABLE 6-1: SUMMARY OF FEDERAL LEGISLATION PERTAINING TO GROUNDWATER REGULATORY ACT APPLICABILITY TO GROUNDWATER AND SURFACE AGENCY WATER EPA Resource Conservation Monitoring and cleanup requirements at disposal facilities. and Recovery Act(RCRA) Protects against leaching of waste into surface and ground waters.

Provides for alternative water INTERIOR supply when mining disrupts groundwater supply of and adjacent landowner; 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. 6-4 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 Construction and establishes licensing for drilling contractors Act WSDOE - 90.44 Regulation of Determines groundwater rights, establishes a Public procedure for appropriating groundwater rights, Groundwaters Issues permits for well construction, and issues certificates for groundwater withdrawal.

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 are 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 different chemical compounds with the soil varies considerably. Phosphorous and potassium, the primary constituents of fertilizers are readily absorbed by soil particles. However, 6-5 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 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 6-6 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 alternativesmay 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 altemative 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 1-405 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 document) Prepared by CH2M Hill Aquifer Protection Study Adopted Resolution No.2553 July 23, 1985 Groundwater Monitoring Movement Study-Data gathered August 8, 1985 986-1987 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 6-7 Aquifer Test June 24-26, 1987 Data Report for the City of Renton Cedar River Valley June, 1987 Aquifer Test RH2 Engineering/Hydrogroup, Inc.

Pursue the repair and/or replacement of all storm and sanitary sewer pipelines in the well field protection area. 8. Continue to install monitoring wells in zone 1 and 2 of the Aquifer Protection area. 9. Continue an active Aquifer Awareness Program. 3. 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 the Department of 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 the Department of 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 the Department of 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 RW1,2,and 3,and PW8 and 9. 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 TABLE 6-3 SUMMARY OF WATER RIGHTS FOR THE CITY OF RENTON WATER SUPPLY SOURCES Water Dept.of Amount of Current Capacity Right Ecology Water Right of Source Source of Supply Status File No. (GPM) (GPM) Springbrook Springs Certificate 463 1,032 600 Certificate G1-02605 1,050 Well No. 1 Certificate 886-0 1,040 Certificate 5838-A 960 Well No.2 Certificate 887-0 1,040 Certificate 5836A 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 844-0 170 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 Well No. 11 Temporary Permit G1-24781 1,600 2,500 Application G1-25396 1,400 Well No. 12' Temporary Permit G1-24782 1,600 1,600 Well No. 14' Temporary Permit G1-25069 1,600 1,600 Well No. 15' Temporary Permit G1-25070 1,600 1,600 Well No. 16' Temporary Permit G1-25071 1,600 1,600 Well No. 17 Application G1-25397 3,000 1,500 •Proposed wells currently in the planning phase Two significant changes have occurred with the status of the City's water rights since the publication of the 1983 Water Comprehensive Plan: 1. 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 PW 1,2,and 3 are in the process of being transferred to the replacement wells RW1, 2, and 3. Production wells PW1 and 2 have been abandoned. However,production well PW3 still remains operational. 6-10 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, the Department of 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), the Department 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 the Department to reserve water for future public water supply. The City is working closely with the Department of 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.the Department of 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 lnstream 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 require 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. 4. WATER QUALITY The City's existing supply sources have been in the past 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 6-11 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 levelsfor eight (8) 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. Pesticides, Trihalomethanes, Volatile and Synthetic Organic Chemicals TABLE 6-6 summarizes the organic chemical data for the City's supply sources. The USEPA has established National Primary Drinking Water Regulations for volatile organic chemicals (VOC). Under these standards, maximum contamination levels have been set for eight(8)regulated VOC's. in addition,51 other VOC have been recommended for monitoring which include the four organic chemicals known as the Trihalomethanes. Chemical analyses of the City's supply sources show no contamination from volatile organic chemical or pesticides. Renton should continue to promote production of the highest quality water possible. 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 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 V.O.C.'s, 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 Ciry 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: 6-12 TABLE 6-4 SUMMARY OF RAW GROUNDWATER BACTERIOLOGICAL ANALYSES RENTON GROUNDWATER WELLS DATE March September Sept Nov.

Begin a program to remove all lead joint pipe and other distribution system items which are potential contributors of lead in the drinking water. Maintain communications with State and Federal regulatory agencies regarding new and pending lead related legislation. Comply with all requirements. Discourage the use of 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. 6-13 TABLE 6-5 SUMMARY OF INORGANIC AND PHYSICAL CHEMICAL ANALYSES RENTON WATER SUPPLY SOURCES PROPOSED RENTON WELL SUPPLIES SPRINGBROOK CITY WATER QUALITY PARAMETER LEVEL(MCL) RW-1,2&3 PW-3 PW-8 PW-9 SPRINGS HALL _________=====================___ gra.mar____--_---_- .r--r.--. _____._r.i...r--------a-S .. ...----- INORGANIC CHEMICALS (mg/I) (mg/I) (mg/I) (mg/Q (mgM) (mg/I) (mg/I) Barium 5.000 < 0.25 < 0.25 < 0.25 < 0.25 < 0.25 Cadmium 0.005 < 0.002 < 0.002 < 0.002 < 0.002 < 0.002 <0.002 Chromium 0.100 < 0.01 < 0.01 < 0.01 < 0.01 < 0.01 Copper 1.300 0.018 Fluoride 2.000 < 0.2 < 0.2 < 0.2 < 0.2 < 0.2 Lead 0.005 < 0.01 < 0.01 < 0.01 < 0.01 < 0.01 < 0.01 Mercury 0.002 < 0.001 < 0.001 < 0.001 < 0.001 < 0.001 Nitrate (as N) 10.000 0.52 0.76 0.42 0.43 2.7 Nitrate (as N) 1.000 Selenium 0.050 < 0.005 < 0.005 < 0.005 < 0.005 < 0.005 UNREGULATED INORGANICS Arsenic 0.050 < 0.01 < 0.01 < 0.01 < 0.01 < 0.01 Chloride 250.000 < 10 13 < 10 < 10 < 10 Iron 0.300 0.06 0.08 0.05 0.06 0.07 0.03 Manganese 0.050 < 0.01 < 0.01 < 0.01 < 0.01 < 0.01 Sodium < 10 < 10 < 10 < 10 < 10 Silver 0.050 < 0.01 < 0.01 < 0.01 < 0.01 < 0.01 Sulfate 250.000 Zinc 5.000 0.077 PHYSICAL CHARACTERISTICS Asbestos (mil fibers/1) 7.000 0 Color (color units) 15 < 5.0 < 5.0 < 5.0 < 5.0 < 5.0 Conductivity (mhos/cm) 700 86 220 81 160 210 Giardia Lamblia 0 Hardness 48 110 38 72 94 Total Dissolved Solids 500 98 Turbidity 0.1 NTU 0.06 0.07 0.05 0.05 0.08 PH 5.5 Langlier Index @ 45° F -3.5 @ 50° F -3.3 8 55° F -3.3 6-14 TABLE 64 SUMMARY OF ORGANIC CHEMICAL ANALYSES RENTON WATER SUPPLY SOURCES MAXIMUM RENTON WELL SUPPLIES SPAINGBROOK CITY WATER QUALITY PARAMETER LEVEL(MCL) RW-1,2&3 PW-3 PW-8 PW-9 SPRINGS HALL SYNTHETIC ORGANIC CHEMICALS UG/1 (ugh) (ugh) (ugh) (ugh) (ugh) (ugh) Endrin 0.2 < 0.02 < 0.02 < 0.02 < 0.02 < 0.02 Lindane 4.0 < 0.02 < 0.02 < 0.02 < 0.02 < 0.02 Methoxychlor 100.0 < 0.1 < 0.1 < 0.1 < 0.1 < 0.1 Toxaphene 5.0 < 5 < 5 < 5 < 5 < 5 2, 4-D 100.0 < 2 < 2 < 2 < 2 < 2 2,4,5-TP (Silvex) 10.0 < 1 < 1 < 1 < 1 < 1 VOLATILE ORGANIC CHEMICALS Benzene 5.0 0.5 < 0.5 < 0.5 < 0.5 < 0.5 Vinyl Chloride 2.0 .5 < 0.5 < 0.5 < 0.5 < 0.5 Carbon Tetrachloride 5.0 < 0.5 < 0.5 <. 0.5 < 0.5 < 0.5 1,2-Dichloroethane 5.0 < 0.5 < 0.5 < 0.5 < 0.5 < 0.5 Trichloroethylene 5.0 < 0.5 < 0.5 < 0.5 < 0.5 < 0.5 1,1-Dichloroethane 7.0 < 0.5 < 0.5 < 0.5 < 0.5 < 0.5 1,1,1-Trichloroethylene 200.0 < 0.5 < 0.5 < 0.5 < 0.5 < 0.5 P-Dichlorobenzene 75.0 < 0.5 < 0.5 < 0.5 < 0.5 < 0.5 Tetrachloroethylene < 0.5 < 0.5 < 0.5 < 0.5 < 0.5 TOTAL TRIHALOMETHANES 100.0 30.5 21.8 28.4 26.1 Chloroform 25.0 19.2 18.3 14.5 Bromodichloromethane 2.7 2.1 8.9 8.2 Bromoform < 0.5 < 0.5 < 0.5 < 0.5 Chlorodibromomethane 2.8 0.5 1.2 3.4 6-15 Chapter Seven POLICIES AND DESIGN CRITERIA 0 12 , _______r_ 9 3 4,11 _.8 4 \\ i`, /V 7 6 5 -lir '''=-..: - \ / �` :\ Mar —9 . 61333 is C= o a c U Lq ; // 4. _ '''' / ---.-- ••••,..._ 7 II 7\ _ 3w;;;;;mii,,,,' ' ''' .a .... .....„ .,.„,,........... _ ,___ __ N._•, .__ _____7. ilk<„:„. .,____:,......_------- , de -- ,-, .1, =____„ , _. #,, .._., _ . , , ____ ,. / , ___, 0 . ______ _„;_,.. -,-,. ..... ________ ,. iiii• \ 11111.1_ Chapter Seven POLICIES AND DESIGN CRITERIA I. INTRODUC77ON 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 State Regulations 1 Renton City Council Renton Mayor 7-1 Public Works Administration i}rl 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. The highest three levels of establishing policies and laws, 1)Federal Regulations,2)State Regulations,and 3)Renton City Council, dictate requirements that are sat 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. ft 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 will be identified in this Chapter. 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. 7-2 TABLE 7-1 CITY OF RENTON WATER UTILITY POLICY OUTLINE SERVICE li. v• v 1r i ..

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. • Renton will follow state guidelines in the assumption of facilities in annexation areas. • Service to areas outside of the City limits without annexation will be evaluated on a case by case basis by the City Council. • Do not mix Renton Water with water supplied by other systems. 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 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 and the Environmental Protection Agency. • 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. 7-4 - 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 user rates will include debt service incurred to finance the capital assets of the utility. • New customers seeking 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 determination of 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 to provide cash for the expenses of operating 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 growth rate used to project customers and demand will be based on historical experience, not on statistics used for comprehensive planning or facility design. This is a financially conservative approach. • 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. • For customers residing outside the City limits, water rates are 1.5 times the residential City rates. • The utilities 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. 7-5 • The water utility provides fire protection services in addition to water services. A separate cost allocation for fire protection services should be established. • The utilities'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 utilities 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. • 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, owner of properties which have not been assessed or charged or borne an equitable share of the cost of the water distribution and water plant facilities shall pay prior to connection to a water main one or more of four special connection charges: 1. Latecomer Fees. PerOrdinance#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 including the wells, pump stations, reservoirs, and transmission mains. The charge shall be: 7-6 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 cents 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. • 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 PRV's. • Maximum allowable pressure suppression during normal demands is 30 psi. • During fire conditions, theminimum 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 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. The Seattle supply meters will remain operational, however, 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, including 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. 7-7 Storage(source: 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. • Fire flow 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. • Provide sufficient emergency storage 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, 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 American Water Works Association as follows: 1. In residential areas, the grid of distribution mains should consist of mains at least 6-inches in diameter arranged so that the lengths on the long sides of block between intersecting mains do not exceed 600 feet. Where longer lengths of pipe are necessary,8-inch 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-inches should be the minimum main size. 2. In high-value districts,the minimum size should be 8-inches with intersecting mains in each street;12-inches 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. • Distribution System design assumes that only adequately sized service line will be used. All residential service lines will be 3/4-inch or larger copper, according to City ordinance. Service lines will be the same size as the meter. 7-8 • 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 of installing services. A minimum of 3 valves shall be provided per cross, and 2 valves per tee. 3. AirNacuum 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. 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. 7-9 • 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.

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 fisted 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. As can be seen,only the.196 zone and Talbot Hill 350 zone have adequate supply to comply with the policy and design standards. At saturation,all areas will require additional supply capacity except the Talbot Hill 300 zone. The following improvements are necessary, and are summarized in TABLE 8-2.

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 1000 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 needod under 4 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 8-3. The storage volume necessary using standard 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: • 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 at an elevation necessary to provide the highest elevation service in the zone with a pressure of 40 psi at maximum day. 8-4 Table 8-3 Standby Storage Requirements Based On Failure Probability Analysis Largest MDD" Largest Source Reservoir No Source Mechanical Power Out of DOH Failure Failure Failure Failure Service Failure 1987 (MG) (MG) (MG) (MG) (MG) (MG) Operating Area Downtown 196 Zone 0.00 0.00 0.00 10.20 0.00 1.50 Highland 435/Kennydale 320 0.00 8.60 0.00 8.60 N/A 0.40 Highlands 565 0.00 0.00 0.00 0.00 N/A 0.43 West Hill 490/270 0.00 0.94 0.00 0.00 N/A 0.27 Rolling Hill 590/490/350/300 0.00 0.00 0.00 0.00 N/A 0.26 Largest MDD" Largest Source Reservoir No Source Mechanical Power Out of DOH Failure Failure Failure Failure Service Failure Saturation (MG) (MG) (MG) (MG) (MG) (MG) Operating Area Downtown 196 Zone 0.00 0.00 0.00 0.00 0.00 2.40 Highland 435/Kennydale 320 0.00 7.40 0.00 0.00 N/A 1.00 Highlands 565 0.00 0.00 0.00 0.00 N/A 1.30 West Hill 490/270 0.00 0.00 0.00 0.00 N/A 0.28 Rolling Hill 590/490/350/300 0.00 3.50 0.00 0.00 N/A 0.75 "MDD-Maximum Day Demand • 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. Each operating area was analyzed based on the policy criteria listed above, using the 5 peak demand days in 1987. A saturation storage requirement was calculated by increasing the hourly 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. 8-5 It should be noted that two different operating areas with the same number of ERU's 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 in a system wide basis. The criteria for calculating storage in each operating area is listed below: 196 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). 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.).

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). 8-6 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.

The remaining supply to the zone is from the Fred Nelson Pump Station(925 gpm), Tiffany Park Pump Station(1,050 8-7 gpm), PRV No. 28(1365 gpm), and the Scenic Hill PRV's (110 gpm). At saturation, an additional 5,000 gpm will be available from the Maplewood pump station.

At saturation an additional 1,400 gpm of supply will be available from the Black River pump station.

Fire Flow 2,000 gpm Duration 5 hours Volume 600,000 gallons (1987) Fire Flow 2,000 gpm Duration 5 hours Volume 600,000 gallons (saturation) 8-8 The following TABLE 8-4 summarizes the storage requirements for the City's service area: As can be seen, each operating area is deficient in storage for current demand conditions. 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 basis 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 8-4 the distribution system analysis has indicated that additional fire storage is necessary in the Springbrook Springs area,and 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 8-5. 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). 2.. Highlands 435 Kennydale 320: Increase zone storage by 7.4 million gallons. 3. Highlands 565: Increase zone storage by 2.0 million gallons. 4. Rolling Hills 590/590/350: Increase zone storage by 5.0 million gallons. 5. West Hill: Increase zone storage by 0.3 million gallons. 4. 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 four feet per second(fps)during peak demand periods, and less than eight feet per second 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 four fps during normal demand and eight fps during a fire: • Fireflow capacity was insufficient to meet the fire fighting requirements at a particular location. • Pressure criteria fisted in the preceding chapter were not met. 8-9 Table 8.4 Storage Summary Equalizing Storage 1987 Saturation Downtown 196 290,000 2,250,000 Highlands 435/Kennydale 320 110,000 1,420,000 Highlands 565 570,000 1,170,000 Rolling Hills/Talbot Hill 230,000 1,000,000 West Hill 130,000 340,000 Fire Flow Storage 1987 Saturation Downtown 196 2,160,000 2,160,000 Highlands 435/Kennydale 320 2,160,000 2,160,000 Highlands 565 1,500,000 1,500,000 Rolling Hills/Talbot Hill 2,160,000 2,160,000 West Hill 600,000 600,000 Standby Storage 1987 Saturation Downtown 196 10,200,000 0 Highlands 435/Kennydale 320 8,600,000 800,000 Highlands 560 0 0 Rolling Hills/Talbot Hill 0 3,500,000 West Hill 940,000 0 Total 1987 Saturation Existing — Downtown 196 12,650,000 4,410,000 8,000,000 Highlands 435/Kennydale 320 10,870,000 4,380,000 3,500,000 Highlands 565 2,070,000 2,670,000 750,000 Rolling HiIls/Talbot Hill 2,390,000 6,660,000 1,800,000 West Hill 1,670,000 940,000 1,400,000 Deficit 1987 Saturation Downtown 196 4,650,000 0 Highlands 435/Kennydale 320 7,370,000 880,000 Highlands 565 1,320,000 1,920,000 Rolling Hills/Talbot Hill 590,000 4,860,000 West Hill 270,000 0 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.

This reservoir will be used to provide fire flow storage and to stabilize pressures 9-1 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. C/P Project No: 32 Cost: $3,500,000 Completion: 2020 Black River 196 Zone Reservoir Construct a water storage reservoir in the Black River 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 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. C/P Project No: 55 Cost: $2,750,000 Completion: 2005 Maplewood Goff Course Well Numbers 10, 11, 12, 14, and 17 Construct wells (and booster station facilities) in the Maplewood Golf course area to provide as much as 10,400 GPM of additional supply capacity 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 reducing loading on the supply to the 196 zone). CIP Project No: 20 Cost: $3,527,000 Completion: 1992 Springbrook Springs Reclamation Engineering investigation of reclamation alternatives and construction of facilities to restore the output from Springbrook Springs.

This reservoir will provide 3.0 million gallons of the 7.3 million gallons storage deficit in the Highlands 435 and Kennydale 320 zone. 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. C/P Project No: 1 Cost: $3,150,000 Completion: 2015 Coulon Park Pump Station Construct a booster pump station in the Coulon Park area to pump from the Downtown 196 Zone to the Kennydale 320 zone with a capacity of 5,000 gallons per minute. The 5,000 GPM will reduce the additional saturation supply requirement of 11,200 GPM to the Highlands 435 zone by reducing the loading on the existing pump stations that supply the 435 zone(the current supply to the 320 zone).

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. C/P 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 5. C1P 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 9-6 be provided by the South Highlands Pump Station and the Maplewood Pump Station(which will supply the 565 zone and therefore reduce the loading on the 435 zone). CIP Project No: 10 Cost: $364,000 Completion: 1990 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 gallons per minute 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: $3,714,000 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 gallons per minute. 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 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.

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,and can 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.

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 in 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 a 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 provided by either the Maplewood Pump Station or the Scenic Hill Pump Station. CIP Project No: 26 Cost: $2,365,000 Completion: 1993 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 gallons per minute 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 No. 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.

The 2,400 gallons per minute will provide more than the 900 gallons per minute 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.

The water utility maintenance section is supervised by Mr. Ray Sled who reports to the Field Maintenance Supervisor Mr. Jack Crumley, who in turn reports to the Public Works Director. Mr. Sled, supervises the day to day 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 Ill". 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 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. As the complexity of the system increases and as the service area expands, the need for trained,efficient staff to keep pace with public demand and advances in technology will become imperative. 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. 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. 70-1 TABLE 10-1 PUBLIC WORKS DEPARTMENT MAINTENANCE DIVISION WATER MAINTENANCE SECTION PUBLIC WORKS DIRECTOR Lynn Butt:a ne FIELD MAWT.SUPERJNTEM ENT .lack Crumlay WATER MANY.SUPERVISOR Ray Sled WATER MMMT.

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 record keeping 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 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. 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 10-3 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. MAINTENANCE EQUIPMENT The existing inventory appears adequate at current staffing levels but should increase in proportion to customer increases. 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 record keeping 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 record keeping requirements of the Washington State Department of Social and Health Services, WAC 248-54-165. DOH has adopted regulations that specify sampling frequencies for physical, bacteriological, and chemical(organic and inorganic)constituents and radionucleides. 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 record keeping 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, providing the supporting data for operations assessment and long-term planning, while saving time and reducing difficulty when trouble arises. 10-4 TABLE 10-3 WATER DEPARTMENT EQUIPMENT(1989) ROLLING STOCK Vehicle# Year Vehicle Description Prime Operator 1989 1 ton utility truck with Cliff Nelson 2-1/2 ton boom 1989 1 ton utility van Jim Koshak B 44 1988 Chevy Astor van Ron Druce C 142 1987 1/2 ton Toyota pickup Ray Sled B 36 1987 Chevy step van Charlie Ruffin C 134 1986 Chevy S-10 van George Stahl D 49 1986 1 ton Chevy utility truck John Jury C 122 1985 Chevy S-10 pickup Bernie Hiatt C 113 1983 1 ton Chevy utility truck C 107 1982 3/4 ton Dodge pickup C 106 1982 3/4 ton Dodge utility truck C 101 1981 1/2 ton Dodge utility truck C 100 1981 1 ton Dodge utility truck C 95 1980 1 ton Dodge utility truck HEAVY EQUIPMENT Vehicle# Year Vehicle Description Prime Operator 1989 Back hoe John Jury S 121 1985 Sullivan air compressor E 63 1982 Ford back hoe D 43 1981 Ford 5 ton flatbed truck D 42 1980 GMC 5 yard dump truck D 35 1977 Ford 5 yard dump truck S 84 1965 Trailer with welder E 68 1981 Hyster fork lift OTHER EQUIPMENT Amount Vehicle Description 4 Wacker compactors 1 3-Inch trash pump 4 Trash diaphragm pumps 1 4-inch to 10-inch tap machine 2 1-1/2"to 2-inch tap machine 2 3/4"to 1-inch tap machine 1 Chainsaw 6 Air pack 4 CL2 repair kits 1 Set of emergency lighting 1 Emergency generator 10-5 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 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 record keeping 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, enforced by Renton's Building Inspection Division. Mr Ron Druce is the designated cross connection control specialist for the City's back flow preventors. The City has implemented the cross-connection program by compiling a list of cross-connection control devices in the system,checking the devices, and reviewing any proposed new development to identify the need for cross-connection control devices. The current edition of"The Accepted Procedure and Practice in Cross-Connection Control"published by the Pacific Northwest Section of the American Water Works Association,is used as a resource on cross-connection control operating policies. The City should survey customers that could potentially cause pollution through backflow. These should include industries, the hospital,and the Metro sewage treatment plant. These facilities may require the installation of backflow prevention devices if a hazard is identified as a result of the cross-connection control survey. The DOH District Engineer may be helpful in assisting the City's forces in determining the risks which exist at these facilities. New commercial and residential facilities are inspected by the Renton Building Department to ensure that no cross- connections exist. Existing residences and commercial buildings,especially those which may have a higher than normal risk, should be inspected to determine that no cross-connections exist. If cross-connections are found, the building owner should be notified,ordered to eliminate the cross-connection and the premises should be inspected again when the required corrections are made. 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. 10-6 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 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. 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-inch to 2-inch meters, and inspect all parts, replace worn or defective parts;retest meter for accuracy. 10-7 Annually: Inspect all 3-inch and larger meters and test. Control Equipment Semiannually: Check calibration of transducers and primary sensing units;adjust as necessary. As Needed: Replace 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 the 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 staff include inspection,testing,installation and repair of system facilities and routine preventive maintenance, record keeping, 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 10-4. For the preventive maintenance alone, the annual hours total 16,920,or325 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. 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 10-3 lists the staffing time necessary for work not associated with preventive maintenance (operation). 10-8 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. 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 record keeping,billing,public relations, communications and other general functions of support staff are performed with the accuracy, timing and regularity required. 10-9 TABLE 10-4 STAFFING TIME FOR PREVENTIVE MAINTENANCE MINIMUM QUANTITY FACILITY OR FREQUENCY OF IN SYSTEM TIME PER TIME REQUIRED EQUIPMENT MAINTENANCE (NO.

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 water 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 5 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 demand, 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 5 year Capital Improvement Costs are summarized below: Year Capital Improvement Costs 1989 $2,524,000 1990 $3,230,000 1991 $3,442,000 1992 $2,597,000 1993 $3,269,000 1994 $4,043,000 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 Water Utility include salary and supply 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 applicable to 50%of the work force. Other expenses are anticipated to increase at a rate of 5%. 11-1 The estimated operating costs are summarized below: Year Estimated Operating Cost 1989 $4,319,000 1990 $5,195,000 1991 $5,738,000 1992 $6,100,000 1993 $6,525,000 1994 $7,155,000 4. REVENUE The estimated revenue for the Water Utility includes sales of water, 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 $6,398,000 1990 $8,408,000 1991 $9,180,000 1992 $8,697,000 1993 $9,794,000 1994 $11,198,000 5. FINANCIAL ANALYSIS TABLE 11-1 summarizes anticipated revenues and expenses for the Water 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.) 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 water utility, using the following water rate schedule for 1989.

The structure allocates costs for providing average annual customer demands(base), maximum day and hour demands(extra capacity), and costs for meters, services, billing and collection. The details of this structure are contained in the Rate Analysis, and can be summarized as recovering the costs for Meters,billing and service in the base rate monthly meter charge, and then allocating a uniform rate for all water consumption. 6. RATE COMPARISON TABLE 11-2 shows a comparison of water rates between the City of Renton and several adjacent water 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: 1. Efficient operation 2. A revenue basis wherein existing customers are not paying for improvements to accommodate growth. 3. Exhaustive efforts to reduce the water utility budget. 4. Successful pursuit of grant funding for eligible items. 11-3 / / TABLE 11-2:1990 WATER RATE COMPARISON MONTHLY CHARGE PER 900 C.F. 2 i ;; • I: • l ; ` j 1 j: ,:$ I"IL!.11 % ` %cl \ :, . s %- -- • --- ; -- \ \ \ 0 i , \ \ y \ itii ::.;:.� % • %-� is--- — - i\ ` � � Vii: Vii‘: ; : Vii: Vii: Vii ' Vii' Vii: - Vii; RENTON TUKWILA KENT AUBURN SEATTLE BELLEVUE REDMOND KIRKLAND W.D.107 SOOS CREEK MUNICIPALITY ED WATER RATES ED SEWER RATES ®COMBINED RATES , / APPENDIX A WELL, BOOSTER, PRV DATA SHEETS APPENDIX A BOOSTER PUMP STATIONS DESCRIPTION SUMMARY Booster Pump Station No.of Total Pressure Zone Facility Comm.

SUPPLEMENTAL SHEET FOR NON-PROJECT ACTIONS (do not use this sheet for project actions) Because these questions are very general,it maybe helpful to read them in conjunction with the list of the elements of the environment. When answering these questions,be aware of the extent the proposal,or the types of activities likely to result from the proposal,would affect the item at a greater intensity or at a faster rate than if the proposal were not implemented. Respond briefly and in general terms. 1. How would the proposal be likely to increase discharge to water: emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise? The 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. Proposed measures to avoid or reduce such increases are: Does not apply. 2. How would the proposal be likely to affect plants, animals, fish, or marine life? The Plan would not directly affect plants, animals, fish, or marine life. 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. 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, floodplains, 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. Proposed measures to protect such resources or to avoid or reduce impacts are: See above. 5.

(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 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(ADDI. 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(ADD!), 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 difference between 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. 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) fire flow 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 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 fire flow storage efficiently without cavitation in the distribution system pipelines or contamination in a customer's service.

The purpose of this Cross Connection Control Plan is to document the planning,implementation, and policies of the City of Renton's Cross Connection Control Program,and to comply with Department of Health requirements for a Cross Connection Control Program. PURPOSE OF PROGRAM: The production and preservation of a public potable water supply is one of the greatest priorities of a water purveyor. Once drinking water has been produced,provisions must be made to ensure that it will not be contaminated with tainted water or substances from other sources. Every person or institute that consumes City water poses a potential hazard to the public water distribution system, and therefore,must be examined for connections between the City's water system and any other water or chemical system. These connections are known as "cross connections" and where they cannot be eliminated,they should be controlled by approved backflow prevention assemblies. The purpose of the Renton Cross Connection Control Program is to establish recommended procedures to be used to protect the public potable water supply from the possibility of contamination or pollution due to existing or potential cross connections. This protection of the water consumers' health is maintained by ensuring the proper installation and surveillance of backflow prevention assemblies when actual or potential cross connections exist and cannot be eliminated. This manual is intended to aid users in implementing an effective Cross Connection Control Program. Using it in conjunction with the "Accepted Procedure and Practice in Cross Connection Control Manual", published by the American Water Works Association (Pacific Northwest Section) will provide the information necessary to ensure that the proper steps are taken towards reviewing existing and new facilities and that proper procedures are followed in the installation and inspection of backflow prevention assemblies HOW TO USE THIS MANUAL: This manual is arranged in five major sections. Chapter 2 documents the City's policies which govern this program and outlines the organization and responsibilities of the involved sections of the Department of Planning/Building/Public Works. Chapters 3 and 4 outline the design criteria and standards implemented by the City. Chapters 6 and 7 document the approved assemblies and certified testers which must be used to conform to State and City regulations Chapters 9 and 10 provide reference material which should be made available to the public to aid in understanding and conforming to Cross Connection Control Requirements. , 1 Chapter Two CITY POLICIES , , CHAPTER II CITY POLICIES INTRODUCTION This chapter identifies those policies associated with the "Cross Connection Control Manual" and Program. Table 2-1 show the relationship of Federal, State, and City regulatory requirements, while Table 2-2 shows the relationship of the Utility Systems Division, and the Development Services Division in the administration of the Cross Connection Control Program. A flow chart of the plan review process is shown in Table 2-3. This identifies the area in each approval process where cross connection control issues are important. Exhibits 2-1 through 2-3 are City standard forms for,Notice of Test,Test Report,and Notice of Test Requirement. These forms are used and administered by the Water Utility Staff to assure testing requirements are met, and to maintain an accurate data base of Cross Connection Control Assemblies. A list of City personnel that are qualified as Cross Control Connection Specialists are included at the end of this chapter. This list should be revised as necessary and maintained in a current edition of the Cross Connection Control Manual. The following is a list of Cross Connection Control Policies: SUPPLY POLICY: In accordance with the policies adopted in the Comprehensive Plan, the Utility Staff will operate to: "Provide the highest quality water in sufficient quantity to meet the needs of the City" The City of Renton Water Utility has accepted the responsibility of supplying safe drinking water throughout the City. Part of this responsibility includes ensuring that the water is not contaminated before it reaches the consumer, due to backflow of contaminated water into the distribution system. To maintain a high quality water supply the city shall enforce the following policies: Policy: - Ensure that existing backflow prevention assemblies are maintained in an operating condition in compliance with the Cross Connection Control Manual. Action: - Maintain a testing program wherein the City informs all backflow prevention assembly . owners of their responsibility to have their assembly tested annually by a certified tester. Keep records on all existing assemblies and verify that each passes an annual test. - Provide random spot inspections of existing assemblies to verify that they are properly installed and in working order. Replace existing assemblies which were previously listed as approved but are no longer on the most current Approved Cross Connection Control Assemblies list. These assemblies may remain in service until maintenance is required Policy: - Minimize the potential hazards of new cross connections Action: - Review plans for new construction to identify potential cross connections. - Instigate procedures which will route all requests for new service or enlargement of existing services to the Plan Review Section for identification of any cross connections. Establish a program that would require that plumbing plans be submitted along with construction plans for approval before a building permit is issued. Policy: - Minimize the potential hazards of existing cross connections Action: - Update and maintain a list of all existing cross connections and backflow prevention assemblies throughout the city. • Establish a reconnaissance program which inspects existing facilities for actual or potential cross connections.This should be an on-going endeavor which concentrates on high risk facilities (see WAC 248-54-185 (2)(a)(iv) for list). • - Inform all owners of heat exchangers and solar domestic hot water systems of the inherent health hazards of their systems, and make available to them the AWWA literature pertaining to such systems. Inform all owners of hot water heaters of the potential hazards of their system. Inform all owners of fire sprinkler systems,both commercial and residential,of the new state requirements regarding these systems,and require all owners to upgrade to current standards. Policy: - Ensure that any cross connection which can not be eliminated is protected with an approved backflow prevention assembly. • Policy: - Ensure that all Cross Connection Assemblies are in compliance with the City's program, Action: - Terminate water service to any premise where the customer fails to cooperate in the installation,maintenance,testing,inspection,or replacement of any backflow prevention assembly. - Make available to the public all information necessary to be in compliance with the City's Cross Connection Control Program ORGANIZATIONAL POLICY j "Provide sufficient staff to achieve all policy goals" Two sections within the Department of Planning/Building/Public Works will be responsible for administration of the Cross Connection Control Program. The Water Utilities Section within the Utility Systems Division and the Plan Review Section within the Development Services Division. To maintain an efficient and effective program the City has adopted the following policies: _ Policy: - The Water Utilities Section will be responsible for implementing Renton's Cross Connection Control Program. Action: - This section shall ensure that annual testings are performed,that records of all actions for each assembly are kept on file, and that an on-going search for existing uncontrolled or unmonitored cross connections are performed. Policy: - The Plan Review Section will be responsible for reviewing all in-coming plans and 1- requests for new construction,and will be responsible for identifyingnew potential cross connections,and assuring that development plans meet the cross connection standards and criteria of the City. Action: - All requests for new service, repair or enlargement of existing services shall be routed through this Department. - All new construction plans shall be reviewed and assessed for cross connections and that any backflow preventer is installed correctly and concurrent with that facility. FINANCIAL IMPACTS The costs to administer this Cross Connection Control Program consists of the personnel costs to review and identify cross connection hazards in the Plan Review Section,and to administer device testing and inspection in the Utility Division.Funding for the program will be provided from the Utility Operating Fund. } I , iY FEDERAL REGULATIONS Environmental Protection Agency Safe Water Drinking Act 1 1 STATE REGULATIONS Department of Health WAC 248-54-285 CITY OF RENTON Department of Planning/Building/Public Works City Ordinance STANDARDS • Accepted Procedures and Practice Uniform Plumbing Code Manual of Cross Connection Control in Cross Connection Control Manual Chapter 10 (Foundation for Cross Connection (American Water Works Association) (International Association of Control and Hydraulic Research) (Pacific Northwest Section) Plumbing and Mechanical Officials) (University of Southern California) REGULATORY STANDARDS FOR CROSS CONNECTION CONTROL Table 2-1 DEPARTMENT OF PLANNING/BUILDING/PUBLIC WORKS V • I ► I UTILITY SYSTEMS DIVISION DEVELOPMENT SERVICES DIVISION WATER UTILITIES SECTION PLAN REVIEW SECTION Overall Program Managment New Construction — Identify Annual Inspections potential cross connections Reconnaissance Work Plan Review — Verify Existing Facilities plan compliance Record Keeping Water Meter Permits DEPARTMENTAL RESPONSIBILITIES FOR CROSS CONNECTION CONTROL Table 2-2 l PLAN REVIEW PROCESS C v I I SEPA/SITE PLAN REVIEW BUILDING PERMIT REVIEW SHORT & LONG PLAT APPROVAL ENERGY I NO RELATED I/ NggL , --{ PLANNING I REQUIREMENTS - POLICE •-• L CIVIL UTILITY . -•-[ STRUCTURES . ` IMPROVEMENTS F__....- REVIEW _ t FIRE PLAN UTILITY COTENTIALDREVIEW REVIEW S CONNECNTIFIED H CITY OF RENTON - PLAN REVIEW PROCESS FOR CROSS CONNECTION CONTROL Table 2-3 CERTIFIED CITY PERSONNEL The following is a list of City of Renton Personnel, who are certified to test cross connection control assemblies.

Installation practices for specific situations are accepted from this chapter without change. They are as follows: - Premise Isolation i - In-Plant Isolation - Extreme Health Hazard 1 - Installations Requiring Continuous Service - Dockside Watering Points and Marine Facilities Heat Exchangers and Solar Domestic Hot Water Systems - Portable Spray and Cleaning Equipment - Miscellaneous Uses of Water from Fire Hydrants Standard Safety Electrical Bonding Wire for Devices it In other situations Renton has adopted more stringent and updated requirements. These cases and their accepted installation practices are as follows: Fire Systems: Due to the quality of water found in private fire protection systems they are to be considered non-potable water systems and treated as such. Since the hazard in these systems vary from a non-health to a health hazard, the backflow protection required by the City shall be commensurate with the degree of hazard of each individual condition. Listed below are those situations which determine the different fire system hazards and the minimum type of backflow protection required for each: A. High Hazard Fire System 11 Situations: 1. All systems which have fire fighting foam connected or the potential for foam to be connected. } 2. Systems where an unapproved water supply is connected to the fire system. 3. Systems in which chemicals or antifreeze has been added. Protection Required: Reduced Pressure Backflow Assemblies or Reduced Pressure Detector Assembly. B. Low Hazard Fire System Situations: All other systems without chemicals, foams, or other water supplies ( added. Protection Required: Double Check Valve Assembly. These fire installation criteria apply to both commercial and residential fire systems. The only systems exempt from backflow protection are residential"flow through" sprinkler systems. These systems are ones in which one portable outlet(ie. toilet or sink) is connected to the end of the sprinkler line, thus preventing water to stagnate inside the lines. Irrigation Systems A. High Hazard Irrigation Systems Situations: 1. Systems where compressed air is used to winterize the lines. 2. Systems that may be subject to flooding. 3. Systems containing an auxiliary pump 4. Systems connected to an unapproved water supply Protection Required: Double Check Valve Assembly Situation: 1. Systems where chemicals or herbicides are injected into the sprinkler lines. - Protection Required: Reduced Pressure Backflow Assembly or Air Gap B. Low Hazard Irrigation Systems Situations: 1. All other, non-hazardous systems. Protection Required: Pressure Vacuum Breaker. OTHER RECOMMENDED PRACTICES The City of Renton requires that all new retrofit installations of reduced pressure principle assemblies and double check valve backflow preventers include the installation of strainers located immediately upstream of the backflow assembly. The strainers are necessary due to both foreseen and unforeseen circumstances occurring in the water supply system such as; water main repairs, water main breaks, fires,periodic cleaning and flushing of mains, etc. These occurrences may "stir up" debris within the water main that may cause fouling of backflow assemblies installed without the benefit of strainers. i , • Chapter Four STANDARD DETAILS CHAPTER IV STANDARD DETAILS INTRODUCTION There are currently five (5) basic types of assemblies which are accepted by the City of Renton to control cross connections. This chapter presents the minimum installation practices and gives a brief overview of each assembly. A more detailed review of these assemblies and the testing procedures for them can be found in the "Accepted Procedure and Practice in Cross Connection Control Manual" r ' AIR GAP 1. Air Gap(AG) must be: a physical separation through the free atmosphere - at least 2 times the diameter of the inlet pipe - in no case less than 1-inch - used either in cases of back pressure and backsiphonage flow - inspected annually .

The purpose of this Cross Connection Control-Plan is to document the planning,implementation, and policies of the City of Renton's Cross Connection Control Program,and to comply with Department of Health requirements for a Cross Connection Control Program. PURPOSE OF PROGRAM: The production and preservation of a public potable water supply is one of the greatest priorities of a water purveyor. Once drinking water has been produced,provisions must be made to ensure that it will not be contaminated with tainted water or substances from other sources. Every person or institute that consumes City water poses a potential hazard to the public water distribution system, and therefore,must be examined for connections between the City's water system and any other water or chemical system. These connections are known as "cross connections"and where they cannot be eliminated,they should be controlled cassemblies. The purpose by of the Rentonapprovedbakflow Cross Connectionprevention Control Program is to establish recommended procedures to be used to protect the public potable water supply from the possibility of contamination or pollution due to existing or potential cross connections. This protection of the water consumers' health is maintained by ensuring the proper installation and surveillance of backflow prevention assemblies when actual or potential cross connections exist and cannot be eliminated. This manual is intended to aid users in implementing an effective Cross Connection Control Program. Using it in conjunction with the "Accepted Procedure and Practice in Cross Connection Control Manual", published by the American Water Works Association (Pacific Northwest Section) will provide the information necessary to ensure that the proper steps are taken towards reviewing existing and new facilities and that proper procedures are followed in the installation and inspection of backflow prevention assemblies HOW TO USE THIS MANUAL: This manual is arranged in five major sections. Chapter 2 documents the City's policies which govern this program and outlines the organization and responsibilities of the involved sections of the Department of Planning/Building/Public Works. Chapters 3 and 4 outline the design criteria and standards implemented by the City. Chapter 5 includes the City Ordinance used to enforce this program. Chapters 6 and 7 document the approved assemblies and certified testers which must be used to conform to State and City regulations Chapters 9 and 10 provide reference material which should be made available to the public to aid in understanding and conforming to Cross Connection Control Requirements. • Chapter Two CITY POLICIES II , , It CHAPTER II CITY POLICIES INTRODUCTION This chapter identifies those policies associated with the "Cross Connection Control Manual" and Program. Table 2-1 show the relationship of Federal, State, and City regulatory requirements, while Table 2-2 shows the relationship of the Utility Systems Division, and the Development Services Division in the administration of the Cross Connection Control Program. A flow chart of the plan review process is shown in Table 2-3. This identifies the area in each approval process where cross connection control issues are important. Exhibits 2-1 through 2-3 are City standard forms for;Notice of Test,Test Report,and Notice of Test Requirement. These forms are used and administered by the Water Utility Staff to assure testing requirements are met, and to maintain an accurate data base of Cross Connection Control Assemblies. • A list of City personnel that are qualified as Cross Control Connection Specialists are included at the end of this chapter. This list should be revised as necessary and maintained in a current edition of the Cross Connection Control Manual. The following is a list of Cross Connection Control Policies: SUPPLY POLICY: In accordance with the policies adopted in the Comprehensive Plan, the Utility Staff will operate to: "Provide the highest quality water in sufficient quantity to meet the needs of the City" The City of Renton Water Utility has accepted the responsibility of supplying safe drinking water throughout the City. Part of this responsibility includes ensuring that the water is not contaminated before it reaches the consumer, due to backflow of contaminated water into the distribution system. To maintain a high quality water supply the city shall enforce the following policies: Policy: - Ensure that existing backflow prevention assemblies are maintained in an operating condition in compliance with the Cross Connection Control Manual. Action: - Maintain a testing program wherein the City informs all backflow prevention assembly owners of their responsibility to have their assembly tested annually by a certified tester. Keep records on all existing assemblies and verify that each passes an annual test. Provide random spot inspections of existing assemblies to verify that they are properly installed and in working order. Replace existing assemblies which were previously listed as approved but are no longer on the most current Approved Cross Connection Control Assemblies list. These assemblies may remain in service until maintenance is required Policy: - Minimize the potential hazards of new cross connections Action: - Review plans for new construction to identify potential cross connections. Instigate procedures which will route all requests for new service or enlargement of existing services to the Plan Review Section for identification of any cross connections. Establish a program that would require that plumbing plans be submitted along with construction plans for approval before a building permit is issued. Policy: - Minimize the potential hazards of existing cross connections Action: - Update and maintain a list of all existing cross connections and backflow prevention assemblies throughout the city. Establish a reconnaissance program which inspects existing facilities for actual or potential cross connections.This should be an on-going endeavor which concentrates on high risk facilities (see WAC 248-54-185 (2)(a)(iv) for list). - Inform all owners of heat exchangers and solar domestic hot water systems of the inherent health hazards of their systems, and make available to them the AWWA literature pertaining to such systems. - Inform all owners of hot water heaters of the potential hazards of their system. Inform all owners of fire sprinkler systems,both commercial and residential,of the new state requirements regarding these systems, and require all owners to upgrade to current standards. Policy: - Ensure that any cross connection which can not be eliminated is protected with an approved backflow prevention assembly. Policy: - Ensure that all Cross Connection Assemblies are in compliance with the City's program, Action: - Terminate water service to any premise where the customer fails to cooperate in the installation, maintenance,testing,inspection,or replacement of any backflow prevention assembly. Make available to the public all information necessary to be in compliance with the City's Cross Connection Control Program ORGANIZATIONAL POLICY "Provide sufficient staff to achieve all policy goals" Two sections within the Department of Planning/Building/Public Works will be responsible for administration of the Cross Connection Control Program. The Water Utilities Section within the Utility Systems Division and the Plan Review Section within the Development Services Division. To maintain an efficient and effective program the City has adopted the following policies: Policy: - The Water Utilities Section will be responsible for implementing Renton's Cross Connection Control Program. Action: - This section shall ensure that annual testings are performed,that records of all actions for each assembly are kept on file, and that an on-going search for existing uncontrolled or unmonitored cross connections are performed. Policy: - The Plan Review Section will be responsible for reviewing all in-coming plans and requests for new construction,and will be responsible for identifying new potential cross connections,and assuring that development plans meet the cross connection standards and criteria of the City. Action: - All requests for new service, repair or enlargement of existing services shall be routed through this Department. All new construction plans shall be reviewed and assessed for cross connections and that any backflow preventer is installed correctly and concurrent with that facility. FINANCIAL IMPACTS The costs to administer this Cross Connection Control Program consists of the personnel costs to review and identify cross connection hazards in the Plan Review Section,and to administer device testing and inspection in the Utility Division.Funding for the program will be provided from the Utility Operating Fund. i 1 FEDERAL REGULATIONS Environmental Protection Agency Safe Water Drinking Act r STATE REGULATIONS Department of Health WAC 248-54-285 1 CITY OF RENTON Department of Planning/Building/Public Works City Ordinance r STANDARDS T • Accepted Procedures and Practice { Uniform Plumbing Code Manual of Cross Connection Control in Cross Connection Control Manual Chapter 10 (Foundation for Cross Connection (American Water Works Association) (International Association of Control and Hydraulic Research) (Pacific Northwest Section) Plumbing and Mechanical Officials) (University of Southern California) REGULATORY STANDARDS FOR CROSS CONNECTION CONTROL Table 2-1 1 -- DEPARTMENT OF PLANNING/BUILDING/PUBLIC WORKS r I UTILITY SYSTEMS DIVISION DEVELOPMENT SERVICES DIVISION WATER UTILITIES SECTION I PLAN REVIEW SECTION Overall Program Managment New Construction — Identify Annual Inspections potential cross connections Reconnaissance Work Plan Review — Verify Existing Facilities plan compliance Record Keeping Water Meter Permits DEPARTMENTAL RESPONSIBILITIES FOR CROSS CONNECTION CONTROL Table 2-2 - - - I- • 1 PLAN REVIEW PROCESS SEPA/SITE PLAN REVIEW BUILDING PERMIT REVIEW SHORT & LONG PLAT APPROVAL ENERGY NO RELATE/ NDCgL PLANNING REQUIREMENTS POUCE • t CIVIL UTILITY STRUCTURES IMPROVEMENTS�- REVIEW FIRE PLAN UTILITY POTENTIAL REVIEW REVIEW CROSS CONNECTIONS • IDENTIFIED HERE CITY OF RENTON PLAN REVIEW PROCESS FOR CROSS CONNECTION CONTROL Table 2-3 • CERTIFIED CITY PERSONNEL The following is a list of City of Renton Personnel,who are certified to test cross connection control assemblies.

Installation practices for specific situations are accepted from this chapter without change. They are as follows: - Premise Isolation - In-Plant Isolation Extreme Health Hazard Installations Requiring Continuous Service j - Dockside Watering Points and Marine Facilities Heat Exchangers and Solar Domestic Hot Water Systems Portable Spray and Cleaning Equipment Miscellaneous Uses of Water from Fire Hydrants Standard Safety Electrical Bonding Wire for Devices In other situations Renton has adopted more stringent and updated requirements. These cases and their accepted installation practices are as follows: Fire Systems: Due to the quality of water found in private fire protection systems they are to be considered non-potable water systems and treated as such. Since the hazard in these systems vary from a non-health to a health hazard, the backflow protection required by the City shall be commensurate with the degree of hazard of each individual condition. Listed below are those situations which determine the different fire system hazards and the minimum type of backflow protection required for each: A. High Hazard Fire System Situations: 1. All systems which have fire fighting foam connected or the potential for foam to be connected. 2. Systems where an unapproved water supply is connected to the fire system. 3. Systems in which chemicals or antifreeze has been added. Protection Required: Reduced Pressure Backflow Assemblies or Reduced Pressure Detector Assembly. B. Low Hazard Fire System Situations: All other systems without chemicals, foams, or other water supplies added. Protection Required: Double Check Valve Assembly. These fire installation criteria apply to both commercial and residential fire systems. The only systems exempt from _ backflow protection are residential"flow through" sprinkler systems. These systems are ones in which one portable 1 outlet(ie. toilet or sink) is connected to the end of the sprinkler line, thus preventing water to stagnate inside the lines. Irrigation Systems A. High Hazard Irrigation Systems Situations: 1. Systems where compressed air is used to winterize the lines. 2. Systems that may be subject to flooding. 3. Systems containing an auxiliary pump 4. Systems connected to an unapproved water supply �_. Protection Required: Double Check Valve Assembly Situation: 1. Systems where chemicals or herbicides are injected into the sprinkler lines. Protection Required: Reduced Pressure Backflow Assembly or Air Gap B. Low Hazard Irrigation Systems Situations: 1. All other, non-hazardous systems. Protection Required: Pressure Vacuum Breaker. �r- OTHER RECOMMENDED PRACTICES The City of Renton requires that all new retrofit installations of reduced pressure principle assemblies and double check valve backflow preventers include the installation of strainers located immediately upstream of the backflow assembly. The strainers are necessary due to both foreseen and unforeseen circumstances occurring in the water supply system such as; water main repairs, water main breaks, fires,periodic cleaning and flushing of mains,etc. These occurrences may "stir up" debris within the water main that may cause fouling of backflow assemblies, installed without the benefit of strainers. I ' Chapter Four STANDARD DETAILS CHAPTER IV STANDARD DETAILS INTRODUCTION There are currently five (5) basic types of assemblies which are accepted by the City of Renton to control cross connections. This chapter presents the minimum installation practices and gives a brief overview of each assembly. A more detailed review of these assemblies and the testing procedures for them can be found in the "Accepted, Procedure and Practice in Cross Connection Control Manual" • AIR GAP 1.

Chapter Five CITY ORDINANCE CITY OF RENTON CROSS CONNECTION CONTROL ORDINANCE TECHNICAL REQUIREMENTS PURPOSE: Under the provisions of the Safe Drinking Water Act of 1974,the Federal Government has established through the EPA,national standards of safe drinking water. These standards,as they apply,to cross connections,are enforced by the State of Washington through the Department of Health. The City of Renton as the water purveyor,has the primary responsibility for preventing water from unapproved sources, or any other substances, from entering the public potable water system. This ordinance, in conjunction with Chapter 10,of the Uniform Plumbing Code, the State of Washington Administrative Code (WAC 248-54-285), and the current edition of Accepted Procedure and Practice in Cross Connection Control Manual,AWWA-Pacific Northwest Section,is to protect the health of the water consumer and the potability of the water in the distribution system. This is accomplished by eliminating or controlling all actual (direct) and potential (indirect) cross connections between potable and non-potable systems through the use of approved backflow prevention assemblies. The City of Renton is required to ensure that such assemblies are properly installed and periodically inspected,and that all new and existing plumbing systems are reviewed for identification of cross connections. APPLICATION: This Chapter applies throughout the water service area of the City of Renton. It applies to all systems installed prior to or after its enactment. Therefore, anyone wanting, or using water from, the City of Renton is responsible for compliance with these regulations and shall be strictly liable for all damage incurred as a result of failure to comply with the express terms and provisions contained herein. ENFORCEMENT: The Director of the Department of Planning/Building/Public Works will administer the provisions of this Chapter. He will designate cross connection specialists and propound all needful rules and regulations to carry these provisions into effect. The Water Utility Section of the Utility Systems Division will be responsible for monitoring and inspecting all existing cross connection assemblies and for keeping all records generated by the Cross Connection Control Program. The Plan Review Section of the Development Services Division will be responsible for reviewing all new and improvement plans for cross connections. DEFINITIONS: AIR GAP: A physical vertical separation through the free atmosphere sufficient to prevent backflow between the free flowing discharge end of the potable water system and the overflow level of the receiving vessel,tank,plumbing fixture or any other system. Physically defined as a distance greater than or equal to twice the diameter of the supply pipe diameter but in no case less than one inch. APPROVED: Approved in writing by the Department of Health or other agency having jurisdiction. ATMOSPHERIC VACUUM BREAKER: An assembly which prevents backsiphonage by creating an atmospheric vent when there is either a negative pressure or sub-atmospheric pressure in the water system. It is designed to protect against backsiphonage only. AUXILIARY SUPPLY: Any water source or system on, or available to, the premises other than the purveyor approved potable water supply. BACKFLOW: The flow of water or any other liquid, gas or substance from any source back into the distribution pipes of the potable water supply system. BACKPRESSURE: Backflow caused by a pump, elevated tank,boiler, or other means that could create pressure within the system greater than the potable water supply system. BACKSIPHONAGE: The flow of water or any other liquid, gases or substances from any source back into the distribution pipes of the potable water supply system caused by the reduction of pressure in the potable water supply • system. BACKFLOW PREVENTER: An approved assembly which prevents the backflow of water or any other liquid,gas, or substance from any source back into the distribution pipes of the potable water supply system. BAROMETRIC LOOP: A fabricated piping arrangement rising at least thirty- five (35) feet at its topmost point above the highest fixture it supplies. It is used in water supply systems to protect against backsiphonage only. CONTAMINANT: A substance that will impair the quality of the water to a degree that it creates a serious health hazard. CROSS CONNECTION: Any physical or potential arrangement whereby a public water system is connected, directly or indirectly, with any other non-potable water system, drain, sewer, conduit, pool, storage reservoir, plumbing fixture,or other device which contains,or may contain,contaminated water, sewer,or other waste liquid of unknown or unsafe quality which may be capable of imparting contamination to the public water system as a result of backflow. Bypass arrangements,jumper connections,removable sections, swivel or change-over devices, or other temporary or permanent devices through which backflow may occur are considered to be cross connections. DOUBLE CHECK VALVE ASSEMBLY: An approved assembly composed of two single, independently acting check valves, either spring loaded or internally weighted, installed as a unit between two tightly closing shutoff valves and having suitable connections for testing. HEALTH HAZARD: A physical or toxic hazard which could be dangerous to health. REDUCED PRESSURE PRINCIPLE BACKFLOW PREVENTER: An assembly consisting of two independently acting spring operated check valves,separated by a spring loaded differential pressure relief valve,which is installed as a unit between two tightly closing shutoff valves and having suitable connections for testing. POLLUTION: A hazard which could cause aesthetic problems or have a detrimental effect on the quality of water in the potable system. POTABLE WATER: Water which is safe for human consumption,as described by the public health authority having jurisdiction. PRESSURE VACUUM BREAKER: An assembly consisting of a spring loaded check valve, and independently operating air inlet valve, inlet and discharge shutoff valve and properly installed test cocks. The air inlet valve is internally loaded to the open position,normally by means of a spring. This internal loading allows the assembly to be installed on the pressure side of a shutoff valve. It is designed to protect against backsiphonage only. INSTALLATION OF BACKFLOW PREVENTION ASSEMBLIES: Backflow prevention assemblies required by this chapter must be installed so as to be readily accessible for maintenance and testing. All assemblies shall be connected at the meter,the property line when meters are not used, or within any premise wherein the judgement of the City of Renton Cross Connection Control Specialist the nature and extent of activity on the premises,or the materials used or stored on the premises could present a health hazard __ should a cross connection occur. This includes: (1) Premises having an auxiliary water supply. (2) Premises having internal cross connections that are not correctable, or intricate plumbing arrangements which make it impractical to ascertain whether or not cross connection exist. (3) Premises where entry is restricted so that inspections for cross connections cannot be made with sufficient frequency or at sufficient short notice to assure that cross connections do not exist. (4) Premises having a repeated history of cross connections being established or re-established. (5) Premises on which any substance is handled under pressure so as to permit entry into the public water system,or where a cross-connecting could reasonably be expected to occur. This includes the handling of process waters and cooling waters. (6) Premises where materials of a toxic or hazardous nature are handled such that if backsiphonage should occur,a health hazard may result. (7) Hospitals,mortuaries, clinics; (8) Laboratories; (9) Piers and docks; (10) Sewage treatment plants; (11) Food or beverage processing plants; (12) Chemical plants using a water process; (13) Metal plating industries; (14) Petroleum processing or storage plants; (15) Radioactive material processing plants or nuclear reactors; (16) Car Washes; (17) Process waters or cooling towers; (18) Fire sprinkler systems; (19) Irrigation systems; (20) Solar hot water systems; (21) Others specified by the Director of the Department of Planning/Building/Public Works Administrator. TYPES OF BACKFLOW PREVENTION ASSEMBLIES REQUIRED: Specific types of backflow prevention assemblies are required in the following conditions: (1) An air-gap separation or reduced principle backflow prevention assembly shall be installed where the water supply may be contaminated by industrial waste of a toxic nature or any other contaminant which would cause a health or system hazard. (2) An air gap must be used between a potable water supply and sewer connected wastes. (3) Lawn sprinkler or irrigation systems,which are supplied by Citywater only,shall be required to have a pressure vacuum breaker. If such system contains an auxiliary pump or is subject to chemical additives a double-check valve ti assembly, air-gap separation or a reduced pressure principle backflow prevention assembly will be required. REQUIREMENTS: A. Water Utilities Section: 1. The Water Utilities Section will perform evaluations and inspections of plans/or premises of all existing facilities and inform the owner by letter of any corrective action deemed necessary, the method of achieving the correction,and the time allowed for the correction to be made. 2.

The purpose of this conservation plan is to present a list of recommended procedures and projects to reduce per capita water consumption by 6 112 percent over a five year period. BACKGROUND The concept for the City of Renton's Water Conservation Program was developed after State approval of the East King County Coordinated Water System Plan(EKCCWSP). That plan requires that each water supply municipality within the study area reduce its five (5) year per capita demand by 6 1/2 percent. Prior to the adoption of the EKCCWSP, Renton's Water Conservation Plan consisted of a series of steps to be taken in the event of a water shortage. However, long term conservation effects were indirectly realized as a result of Seattle's Water Conservation Program. As the primary purveyor,Seattle's conservation plan was directed regionally and positively effected Renton,producing substantial water savings at a minimal cost. Renton's water supply is unique among the members of the Regional Water Association (RWA)--the group of municipalities that completed the EKCCWSP--in that it originates in wells located entirely within the city limits. The aquifers supporting these wells are believed to have sufficient capacity to supply the current and short-term saturation needs of the city,but an additional source is needed for long-term needs. This situation creates a paradox for responsible, system supply planning. Renton must develop and implement a conservation program to comply with the Department of Health requirements following adoption of the EKCCWSP. Renton supports water conservation as a wise and efficient use of natural resources;however,at this time,water conservation works against Renton's simultaneous need to acquire additional water rights to secure its future water supply. To obtain those rights, Renton must demonstrate an increasing demand for water,a requirement in opposition to a water conservation program. In the interests of responsible water-supply management, Renton will comply with the Department of Health procedures outlined in the EKCCWSP. A long-term water conservation program will be a new direction for Renton. Consequently, the program presented in this report will include projects that reduce water consumption as well as projects that help define the need,rationale and cost effectiveness of a water conservation program. OBJECTIVE OF CONSERVATION PROGRAM The objective of the conservation program outlined in this plan is to reduce per capita water use by 6 1/2 percent by 1995, and to compile and evaluate the effects and costs of various water conservation programs. Yearly demand for 1987 will be used as the basis for determining per capita water demand,since this is the year that Seattle began conservation efforts. Because the plan will be completed before the end of the 1990 demand season,it will use the demands in 1989 as a basis for the analytical and technical work and projections. The conclusions in the plan can be modified in later years by using actual data from 1990. 1 REGIONAL IMPACT • The approved conservation plan will be implemented in a phased program throughout the City of Renton's water service area. The water service area is shown in the Comprehensive Plan in Figure 1. The improvements and program outlined in this plan are consistent with the program recommended by the EKCCWSP and with the plan currently adopted by the City of Seattle: This will result in complementary efforts by Renton, Seattle and adjacent water users. IMPLEMENTATION SCHEDULE Although this plan recommends immediate adoption and commencement of conservation efforts, it must be recognized that this program has not been funded for the 1991 fiscal year. Full scale employment of the plan, therefore,may not begin until fiscal 1992. • • i 2 TABLE OF CONTENTS CHAPTER ONE INTRODUCTION 1 BACKGROUND 1 OBJECTIVE OF CONSERVATION PROGRAM 1 REGIONAL IMPACT 2 IMPLEMENTATION SCHEDULE 2 CHAPTER TWO WATER SUPPLY AND DEMAND 1 INTRODUCTION 1 SERVICE AREA 1 SUPPLY SYSTEM 2 SYSTEM DEMAND 3 WATER USE PATTERNS 3 PROJECTED DEMAND 4 TABLE 2-1 5 TABLE 2-2 6 TABLE 2-3 8 TABLE 2-4 9 TABLE 2-5 10 CHAPTER THREE EXISTING & PROPOSED WATER CONSERVATION PROGRAMS 1 EXISTING PROGRAM 1 RELATIONSHIP TO WATER SHORTAGE RESPONSE PLAN 1 BUDGET AND STAFFING 2 PROPOSED WATER CONSERVATION PLAN 3 INTRODUCTION 3 CONSERVATION PROGRAM ELEMENTS 5 PUBLIC EDUCATION 5 School Outreach 5 Speakers Bureau 5 Program Promotion 7 Theme Shows and Fairs 9 TECHNICAL ASSISTANCE 10 Single-Family/Multi-Family Kits 10 Purveyor Assistance/Customer Assistance 11 Technical Studies 11 Unaccounted Water/Leak Detection 12 Nurseries/Agriculture 12 Bill Showing Consumption History 14 High Technology Meters 14 POLICY 17 Require Meters 17 Plumbing Code 17 Landscape Management/Playfields 17 Seasonal Pricing/Inverted Rates 18 Irrigation/Private Wells 19 Utility Financed Retrofit 19 Master Source Meters 20 CHAPTER FOUR PROGRAM EVALUATION AND IMPLEMENTATION 1 PROGRAM IMPLEMENTATION 1 PROGRAM EVALUATION OF PHASED PROJECTS 2 CHAPTER FIVE PROGRAM COSTS 1 PROGRAM COSTS 1 COST BENEFIT ANALYSIS 1 RATE IMPACTS 3 TABLE 5-1 4 APPENDIX A Chapter Two WATER SUPPLY AND DEMAND INTRODUCTION This chapter describes the city's water service area,the existing supply system,and historical and projected system demand. This information will be used to establish base-line demands in the water system and to predict future demands without water conservation. The water conservation reduction estimates can then be used to estimate future demands that would result from the various water conservation projects. SERVICE AREA The study area for this conservation plan is the area currently served by the Renton Water System and the additional areas shown in the Skyway and EKCCWSP Plans. The water service area is shown on FIGURE 3 of the Comprehensive Plan 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 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 will be made to develop a conservation plan for the District's 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 EKCCWSP Plan and Skyway Coordinated Water System Plans. 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 of the Comprehensive Plan. 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 EKCCWSP. 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 conclusions of the Skyway Coordinated Water System Plan and the EKCCWSP 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. Development in the service area is in accordance with the city's Comprehensive Land Use Plan and policies that represent 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 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 in the Comprehensive Plan. 1 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,factors that 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. In other words, we have assumed that commercial and industrial growth will be proportional to population growth. SUPPLY SYSTEM 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 of the Comprehensive Plan. Water supply sources include 6 wells and one artesian spring that are used for normal supply, and 5 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 are pumped from a relatively shallow aquifer. These wells provide 96 precent of the city's supply capacity. The water distribution system serves the valley floors and parts of three surrounding hills: the West Hill, the Highlands,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 the three 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. 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 fire flow reserves. The City of Renton is a unique member of the Regional Water Association--the group that completed the EKCCWSP--in that it has a sufficient water supply consisting entirely of groundwater sources. The EKCCWSP was developed for the majority of the water users within the EKCCWSP boundaries that are experiencing pending,critical water shortages. Renton's aquifers are believed to have sufficient capacity to supply the saturation needs of the city. However,Renton must deal with its long-term,rather than short-term, needs by acquiring additional water rights. This situation presents a paradox for responsible system supply planning and conservation program implementation. To avoid future water shortages and to maintain control over water rates and water quality, Renton must continue to develop its autonomous water supply. The ability to obtain additional groundwater rights decreases every year; in fact, it is widely believed that water rights will be severely restricted, or unavailable in the near future. Water rights cannot be obtained without a demonstrated need for the resource. Developing and implementing a water conservation program as required by the EKCCWSP may affect the City's ability to secure additional water rights. 2 In order to comply with RCW 90.03 and 90.54,Renton will design and implement a water conservation plan with targets that are consistent with Department of Health requirements. Renton will also continue to pursue development of additional water supply sources, and water rights, to meet the future needs and interests of the city's water customers. SYSTEM DEMAND The City of Renton's water users are divided into five customer classifications. 1. Single-Family Residential 2. Multi-family 3. Commercial 4. Public 5. Wholesale Single-family residential customers and multifamily customers are the largest,water-using group in Renton and will account for approximately 69 percent 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. Irrigation demands are the easiest to reduce with conservation practices. 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 ERU's Multi-family customers consist of low-and high-density apartment and condominium complexes. These customers typically use (per unit)approximately 60 percent 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 ERU's. For saturation planning,each undeveloped acre is assumed to equal 13 ERU's. Commercial customers consist of retail and wholesale businesses, light and heavy manufacturing and warehouse operation, schools and businesses. The water demand from these customers is more uniform all year, without significant peaks during the summer. These users were identified as one ERU, unless their meter size was larger than 1". The larger, metered customers were individually evaluated; their specific water use habits were assigned an appropriate number of ERU's 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 ERU's. Demands from commercial customers are difficult to reduce since it is assumed that they operate,out of necessity, at an optimum level of efficiency. Public customers include parks and recreation areas whose demand results largely from irrigation-type uses. They 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. WATER USE PATTERNS Water use data is obtained by analyzing well,pump station and reservoir level records that are recorded by the Telemetry system. Reservoir level records were differentiated on an hourly basis to synthesize flowrate values both into and out of each reservoir. These flowrates were appropriately added to or subtracted from the supply flowrates to develop true water demand on an hourly basis. Accurate records have been available only since 1978: making it impossible to compile system demands for earlier years. Table 2-1 shows an average daily demand for the past 12-year period. 3 Two factors have a large impact on water system demands: population and weather. Table 2-1 shows the combined effect of both of these factors. The effects of population can be eliminated by plotting the demand per water system connection,as shown in Table 2-2. It should be noted that although the average daily demand increased between 1988 and 1989 (Table 2-1), the demand per customer was actually reduced (Table 2-2). It is the purpose of this plan to introduce a third factor to water use patterns: conservation. Since Seattle began its conservation program in 1987,demand per connection per day has reduced from 211 gallons per connection to 196 gallons per connection. Total system demand can be divided into three major components: • Residential Demands (Single- and Multi-Family Services) • Commercial-Industrial,Public Facilities and Other Use Demands • System Losses (unaccounted for water) The three factors(growth,weather,conservation)that affect demand 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 daily 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 daily demands was 2.56:1. Therefore, a major portion of the difference between maximum daily 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 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. k System loss or unaccounted for water, the remaining demand component, is predominantly caused by 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 unaccounted for. Older areas of the system generally exhibit greater per service demand due to increased losses from broken pipes,bad joints,and other exfiltration loss. Losses between 10-15 percent of the total system supply are generally considered acceptable for a system the size of the City of Renton's. The percentage of unaccounted for water during 1987 varied from a high of 33 percent for the period of January through June 1987,to a low of 12 percent during the peak two-month period of July and August 1987. Explanations for the wide variation in these values can be attributed to either actual system losses (leaks,under registration of meters,etc.) or pump station meter errors. PROJECTED DEMAND The basis for water demand in the city's service area is the use of it in 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 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; saturation development is dependent on land use policy adopted by the City Council. 4 CITY OF RENTON HISTORICAL WATER DEMAND / TABLE 2-1 SEATTLE CONSERVATION PROGRAM II I .1111104115 / 0 ❑ 4 Z Q W M 3 w F-- 2 1 0 1 1 1 1 1 1 1 1 - 1 1 1 1978 1979 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 YEAR ® EVJ AVERAGE DAY DEMAND CITY OF RENTON DEMAND PER CONNECTION Z TABLE 2-2 SEATTLE CONSERVATION PROGRAM 4.5 / ....m.

This factor is then applied to the projected population to arrive at a projected demand. An EQUIVALENT RESIDENTIAL UNIT is defined as a service connection that consumes the same amount of water as the average,single-family residence within the service area. A single-family residence by defmition equals 1 ERU. Multi-family dwellings equal 0.6 ERU's per unit. Large and industrial users are converted to ERU's by individually examining water use history. The number of ERU's 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. 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, however, as a basis for saturation planning 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 calculated demand per ERU 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. Future demand is calculated by combining historical demand per ERU in 1987 with population projections. Table 2-3 is an estimate of system growth,using a combination of Gomportz and logistic curves,and observed growth for the Renton area. Table 2-3 shows both system growth without the conservation target and with the conservation target of 6 1/2 percent by 1995. Table 2-4 is a comparison of projected system demand and the supply source development necessary to meet system demands. The phasing of the supply sources is consistent with the capital improvement program shown in the Comprehensive Plan. Table 2-5 shows the affects of a successful conservation program on the phasing of the supply sources. As can be seen, it delays the development of a total supply capacity of 21,000 gpm from 1995 to 1998. In accordance with previous discussions of water rights availability,and the possibility that the conservation program is less effective than planned,Renton will pursue the development of supply sources on the schedule shown in the Comprehensive Plan. Successful conservation efforts can be used to introduce conservatism or safety factors into the supply system. It should be noted that a 6 1/2 percent reduction of 1987 demands results in a 1995 average daily demand per connection of 197 gallons. Actual demand in 1989 was 196.6 gallons per connection per day,which indicates that the 61/2 percent target has already been achieved. In order to comply with Department of Health requirements,the conservation plan must prevent an increase in consumption,but need not reduce it further. Renton will,however, continue to promote water conservation and attempt to reduce the per connection consumption. 7 CITY OF RENTON PROJECTED WATER SYSTEM GROWTH TABLE 2-3 30 28 26 24 22 C7 20 0 18 CCa W 16 CC W o Za 14 CC • o O 12 W >- • 10 0 X Q 8 6 4 2 0 1990 1995 2000 2005 2010 2015 2020 2025 2030 2035 2040 YEAR 0 CONSERVATION TARGET 0 W/0 CONSERVATION 8 CITY OF RENTON SOURCE DEVELOPMENT REQUIRED W/O CONSERVATION TABLE 2-4 30 FUTURE 28 FUTURE 26 FUTURE 24 Cal 22 4 WELL NO. 18 W z a cn CC 2 20 0 v WELL NOS. 11 & 17 U. 18 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 WELL 5 EXISTING SUPPLY 14 12 1990 1995 2000 2005 2010 2015 2020 2025 2030 2035 2040 YEAR PROJECTED DEMAND ORIGINAL SOURCES 9 CITY OF RENTON SOURCE DEVELOPMENT REQUIRED WITH CONSERVATION TABLE 2-5 30 28 • 26 24 S 22 O ii w o I- Z < Qo 20 O g J U. 18 . 16 4 14 it. 12 I I I I I I I I I I I 1990 1995 2000 2005 2010 2015 2020 2025 2030 2035 2040 YEAR PROJECTED DEMAND ORIGINAL SOURCES W/0 CONSERVATION CONSERVATION DEMAND SUPPLY SOURCES W/ CONSERVATION 10 Chapter Three EXISTING & PROPOSED WATER CONSERVATION PROGRAMS This chapter describes the City of Renton's conservation program to date, its relationship to the Water Shortage Response Plan and its budget and staffing. The second half of the chapter presents a general description of the proposed Water Conservation Program and a detailed description of each of its elements. EXISTING PROGRAM Renton approved and implemented a Water Conservation Plan in March 1987. Its purpose was to identify procedures to reduce water consumption within the city in the event of a water shortage. This plan did not identify an on-going, long-term conservation program as a goal because the Seattle Water Department's Conservation Plan had already had a positive effect on the water conservation practices of Renton's customers. Although the city does not have a long-term Water Conservation Program,it has participated in various conservation efforts. When requested to do so by water customers, Renton has participated in public outreach programs which distributed water conservation devices and informational materials. Presentations about water conservation have been given to a variety of service, community and other groups, including the Renton Rotary, Chamber of Commerce, senior groups,professional organizations,and some schools. Since 1981 various water conservation kits have been available to customers and lawn watering gauges have been distributed to them. In addition to these conservation measures, the City is pursuing an aggressive leak detection and repair program. In 1989 the City purchased a sophisticated leak detection device and has located and repaired a significant number of water system leaks. A leak detection survey will be performed in the winter of 1991 when demands are low. The effects of participating in Seattle's Water Conservation Program have been significant as shown in Table 2-1, Demand Per Connection. Table 3-1 shows that although the number of water accounts has increased steadily, overall demand per connection in the system was reduced consistently in 1988 and 1989. Further details of this table are discussed in Chapter 4. RELATIONSHIP TO WATER SHORTAGE RESPONSE PLAN Renton's Water Shortage Response Plan,adopted in 1990,will remain in effect and will be used to react to a short- term water shortage caused by planning inaccuracies or system failures. Some of the procedures and tasks outlined in the Water Shortage Response Plan for reacting to a long-term water shortage are the same as the conservation elements proposed in this plan. The Water Shortage Response Plan did not anticipate a long-term Water Conservation Plan,and therefore some of its tasks are redundant;since they will be put into effect as a result of this Water Conservation Program,they will no longer be effective during a water shortage. The Conservation Plan will be used on an on-going basis to reduce long-term consumption during normal, non-emergency conditions; the elements of the Water Shortage Response Plan that are not redundant will be used during short-term emergencies. The Water Shortage Response Plan should be revised to reflect this situation when it is updated in 1995. BUDGET AND STAFFING Since Renton does not currently have a separate Water Conservation Program, it does not have a separate budget allocation for water conservation procedures. The current work is funded by the general fund and performed by existing staff when time permits. This new conservation plan will require additional staff time for preparing plan elements, as well as for administering and monitoring the program. 1 PROPOSED WATER CONSERVATION PLAN INTRODUCTION The recommended program is comprised of four elements that are designed to meet the conservation target of a 6 1/2 percent reduction. Each element is composed of tasks that are implemented in whole or in part depending upon the size of the water utility. This chapter describes the following conservation program elements that Renton will implement in order to comply with the Department of Health requirements and be consistent with the EKCCWSP Plan: 1. PUBLIC EDUCATION • speakers bureau • program promotion • trade shows and fairs 2. TECHNICAL ASSISTANCE • single-family/multi-family kits • customer assistance • technical studies • leak detection and repair • nurseries/agriculture • bill showing consumption summary • high technology meters 3. POLICY • require meters • landscape management • seasonal pricing/inverted rates • irrigation/private wells • utility financed retrofit The EKCCWSP also recommends that a fourth conservation element be considered by each municipality on an optional basis. These optional tasks include: 4. MERITING CONSIDERATION • mandatory seasonal restrictions • recycling/reuse • no water for golf courses • reduce pressure to 45 psi Within the next five-year planning period it will not be necessary for Renton to implement this fourth, optional conservation task,since the city has already achieved the 61/2 percent reduction target,an accomplishment achieved without full implementation of its own mandatory,three-element,conservation program. In the future,if it becomes necessary to increase the conservation savings,these optional tasks may not be the most efficient or cost effective for Renton. Our research with other westcoast water suppliers indicates alternative procedures may provide greater water savings. We recommend that these alternative procedures be studied if the conservation target is not met byimplementing the first three tasks. 2 In order to evaluate the proposed Water Conservation Plan,its different program elements should be implemented in different parts of the city. At the end of an allotted time period,water consumption in the different areas should be measured and compared. This evaluation process is described in greater detail in Chapter Four. The City's Water Department staff will administer and staff the program elements that are described below;however, outside consultants will prepare educational and promotional materials,and will be used for other technical services, which are identified in the program descriptions that follow. 3 CONSERVATION PROGRAM ELEMENTS PUBLIC EDUCATION School Outreach A water resources awareness and conservation program will be integrated into the science curriculum of local elementary schools for all children in grades 4 through 6. It will teach students in a general way about systems for acquiring, containing and distributing water--the three components of the water utility system. Field trips to wells,pumping stations and reservoirs will further acquaint the students with the water system's components. Films and exercises about a diminished water supply will explain the reasons for the water conservation program. Standard conservation techniques should be discussed to teach the students how to participate in their communities during the summer dry months. The educational program should begin in the spring to prepare children for the conservation activities in the summer months. Beginning the program in 1992 will help us reach our water conservation goals for 1995. Continuing the program into the twenty-first century will help us in developing a water- resource minded community. Educational programs for children will continue into summer by integrating water conservation programs into the park system's programs. They will learn about the water conservation practices necessary to maintain the public pool and grass fields that they use. Schedule: Start - 1992(spring of school year) Completion - Ongoing The largest costs will result from the preparation of curriculum material and the field tours coordinated by the water utilities and school districts. Cost: = $5,000/year Speakers Bureau Local politicians, water utility officials and volunteers will speak to a wide cross-section of community, service, business,private and other groups about the importance of water conservation. They will teach the public about the limits of the water resources available to them and neighboring communities. Audio and visual aids that incorporate statistical data showing the relationships between seasonal water usage and actual size of the water supply will emphasize the necessity for water conservation. Results of past conservation programs in the region, if available, will show the significant effects conservation has had on our limited water resources. The following methods of water conservation will also be discussed:voluntary reductions,flow restriction kits,lawn &garden watering calendars,graduated fee schedules,use permits and other mandatory measures such as rationing. Setting priorities for methods of water conservation will teach the public about complexities of water conservation. The majority of speaking engagements should be scheduled in the spring to prepare the public to conserve water during the seasonally dry period. Several presentations should occur throughout the dry months. If there is a severe 4 water resource problem,several speaking engagements should be scheduled. One should also be scheduled for the winter months when flooding may contaminate water resources. Schedule: Start - 1992(emphasis on summer months) Completion - Ongoing The largest cost will result from advertising and preparation of program materials. Some costs may be incurred from reserving adequate space for the speaking engagements. It is assumed that the speakers presenting this information will volunteer their services to the community. Costs: = $5,000/year Program Promotion A promotional program will advertise the needs and methods for achieving water conservation in the community. Television, radio, newspaper and other publications will increase the public's awareness of water conservation techniques. The degree to which each media is used will depend on the necessity for water conservation. Television and,radio news, newspaper articles and advertisements can effectively educate the general public about common water conservation techniques and quickly inform a wide audience--including those who work outside of the local community--of impending or current water-resource shortages, or system failures. Increased regional cooperation will be one result of such extensive advertising. If long-term decline in water reserves occurs, public awareness and participation will be required in a much more comprehensive water conservation program. Voluntary methods of use reduction such as calendar schedules for lawn & garden watering, installation of flow-restriction devices and reduced personal use of showers will need to be implemented initially. If mandatory measures are required,the news media should be heavily relied upon to notify the public of the implications of not complying with regulations. Publications such as inserts in utility bill mailings, displays at local public facilities (i.e. libraries, schools, post offices,etc.),educational programs implemented in public schools,community speaking engagements and reminder items(i.e.posters,bumper stickers,hose tags,etc.)will also encourage water conservation throughout the community. By including water conservation kits with each new meter installation, the public will become involved with the community's water conservation program. Public information should occur throughout the year about the conservation measures to take during the seasonally dry period. Schedule: Start - 1993 Completion - Ongoing All components of this program will require significant costs. The largest cost will be from the preparation of publications and television and radio public service announcements and buying advertising time and space. The news media should be used whenever possible. Regional cooperation in presenting public service announcements, acquiring advertising space and preparing brochures will help reduce costs. Costs: = $2,500/year 5 Theme Shows and Fairs Booths that are staffed by Water Department personnel and volunteers will be set-up at local fairs and theme shows to promote water conservation techniques and distribute water conservation devices to the public. Demonstrating water conservation techniques will be the cornerstone of the presentation. Pertinent topics for display will include common household water conservation practices and graphs showing impacts of conservation programs and the benefits of drought-resistant plants in drought-stricken regions. Common water conservation devices that will be available at the booth,including flow restriction devices in showers, plastic bottles in the toilet tanks,calendar schedules for lawn and garden watering,and lawn watering gauges. Informational literature will also be available that describes conservation techniques,summarizes the impacts of water conservation efforts on system demands, illustrates drought-resistant landscaping and answers questions about voluntary and mandatory restrictions. Schedule: Start - 1992(emphasis during summer months) Completion - Ongoing A majority of the costs will result from the preparation of the portable displays used for presentation. Devices and publications handed out during the event will increase costs but are essential in helping the public conserve water and retain reference information. These publications can be the same ones used in other program elements. Some additional costs may be incurred for transportation and for personnel to staff the display. The display will be exhibited at community events in the spring and summer months in preparation for the seasonally dry periods. Renton River Days, Aquifer Awareness Day and theme shows at shopping malls will be the most effective events and places. Costs: = $8,800 for 1st year $5,000/year after 1st year 6 TECHNICAL ASSISTANCE Single-Family/Multi-Family Kits The Ci rywill provide inexpensive kits of easily installed water-saving devices to single-family fanly homes and to the owners and managers of apartment buildings and condominiums. These inexpensive devices will include shower flow restrictors,toilet tank water displacement containers,lawn and garden watering gauges and reminder items(i.e.bumper stickers,hose tags,buttons,etc.). Their operation and use will be encouraged through a variety of publications included in the kits, which will also illustrate the importance of water conservation and how the devices can help achieve it. Three methods,and their respective advantages,that can be used to distribute the kits are described below. The first method should be implemented and its results monitored. If better results are required, the next method of distribution should be implemented. 1. Make the kits available at public facilities(i.e.libraries,post offices,schools,etc.),public speaking engagements,fairs and theme shows. Lowest distribution cost. Does not assure that all customers will receive and use the devices. 2. Deliver the kits to each residence. - Meter readers can deliver them during their normal rounds. - Does not assure that all customers will install or use all devices. The increased burden on the meter readers will increase personnel costs. 3. Deliver and install kits at each residence. Meter readers can install them during their normal rounds. They can be installed during an intensive,promotional campaign about water conservation. Will reach the largest portion of the customers. Assumes high liability from complications of installation. Schedule: Start - 1992 Completion - Ongoing The distribution of water-saving device kits should begin as quickly as possible to let the public begin conserving water. The distribution of kits should be continuous in order to remind individuals to use them and to give those individuals who have recently moved into the area an opportunity to participate. i The cost of the water conservation kits and the publications enclosed with them will amount to a significant portion of the overall costs. If regional cooperation is attained,costs will be reduced because a larger number of kits and publications will be purchased. Additional costs will vary depending on the method of distribution. The more intensive distribution programs will increase costs accordingly. Costs: = $6,000/year 7 Purveyor Assistance/Customer Assistance Information explaining the methods and results of the water conservation program implemented in our community will be made available to other purveyors. f} Neighboring purveyors can use the information--the publications and water-saving devices--we will develop to create their own programs. Our offered assistance could allow water utilities to work together in regional programs. Once the results of the initial water conservation program are determined and evaluated,neighboring purveyors and local customers should be notified. Feedback from other purveyors could aid us in further improving our methods of water conservation and marketing strategies for community involvement. Status of the community's water supply should be of utmost concern to the public. Daily reports and weekly reviews will be publicized about what they can expect to achieve. Publicizing the program successes could teach customers how their contributions affected the community and the region's water supply. A customer assistance hotline could be installed for the public to request assistance on water conservation practices. Schedule: Start - 1992 Completion - Ongoing Publication and distribution costs will be the largest percentage of the expenses of this element of the program. Costs: = $2,500 - 1992 $1,000 - 1993 and after Technical Studies Intensive research will be conducted on water use, conservation techniques and the effects of water conservation methods. Research on new methods of water conservation is essential to provide the community with the best possible means of contributing to the program. Everyone involved,including the public,should be continually looking for ways to improve water conservation techniques. Questionnaires could be distributed to the entire community or to a specific area for a given time period to better evaluate the attitudes and practices of the public. A comparative analyses of water conservation methods will be devised that will require dividing the district into study areas. Each area will use a different method, allowing evaluation of its effectiveness on water reduction, changing public attitudes, and its costs. For example,water conservation kits could be distributed differently in each area. In one area, devices would be distributed to local public facilities (i.e.post offices,libraries, schools,etc.) for the public to pick up. In a second area,meter readers would distribute the devices with brochures encouraging their use. In a third area,these devices would be distributed and installed, if the customer allows,by the meter reader or a specified technician. Analyzing water conservation methods used by the public is essential to evaluating their effects. A five-year study period will determine which methods of water conservation promotion, distribution and feasibility will attain the highest level of public participation in this district. Research for new methods of water conservation should be an ongoing effort in order to take advantage of technologies being developed. 8 Schedule: Start - 1992 Completion - 5 years (research on public participation) - Ongoing (research for new methods) The majority of the costs for studies of water conservation methods are the same as those for data collection and evaluation by outside consultants. Most of the materials and personnel used to implement water conservation tasks are the same as other elements of the program. Costs: = $2,500 -1992 $ 500/year -after 1992 Unaccounted Water/Leak Detection Regular and systematic surveys will be conducted of the water distribution system in order to locate leaks,potential problem areas and defective equipment. The city currently has a leak-detection program within the Department of Operations and Maintenance. A sophisticated leak-detection instrument enables personnel to maintain the system at a high level of operational performance. The Department of Operations and Maintenance surveys 52 miles of transmission lines every year, enabling the city to survey the entire system once every four years. There is no reason to incorporate any additional program tasks into the water conservation program at this time. Schedule: Existing and ongoing The Department of Operations and Maintenance is currently responsible for all costs associated with the leak detection program . Costs: = $21,000/year Nurseries/Agriculture Water conservation practices will be applied to agricultural projects,plant selection and maintenance of landscaping and plant nurseries. Agriculture, landscaping and other plant nurseries can more efficiently use water if they are encouraged to use moisture sensors, flow timers,low-volume sprinklers,drip irrigation and other current technologies. They should also be encouraged to distribute information to the public about products for reducing irrigation consumption. The informational campaign about water conservation can inform the public about reducing water for irrigation. Nurseries should be contacted and informed about water conservation methods that apply to them. A list of drought-resistant plants suitable to this climate should be developed. Local businesses should be encouraged to stock a variety of these plants and recommend their use and maintenance requirements to customers. A designated part of a city park or other public area possibly at city hall,should be made into a garden that publicly displays these plans, their names,watering methods and general characteristics. In addition to Water Department staff, landscape architects, horticulturists and other outside consultants would be used to develop program materials and garden concepts. 9 1 The formation of the list and subsequent information on drought-resistant plants should begin long before the regular planting season. Development of the garden should take place early in the planting season and be publicized. Schedule: Start - 1994 Completion - Ongoing (Publication distribution) - 1994 (Garden development) Developing a drought-resistant plant list and publishing information about each of them will comprise a large majority of the costs. Developing a display garden will be a significant portion of the initial costs, depending on the number of plants and size of area developed. Costs: = $12,500 - 1994 $ 2,500 -Each year subsequent to 1994 Bill Showing Consumption History A more detailed billing statement will be designed that teaches customers about their water consumption. The best format would be a bar graph that shows water usage volume as a vertical bar for each month of a thirteen- month period. The customer would be able to quickly compare the previous month's consumption to that of the same month for the previous year, as well as any trends in consumption throughout the previous twelve-month period. A superimposed line showing average water usage volume for each month in the district would allow the customers to compare their rate of consumption to that of the community. Tabular data showing the percentage increase or decrease in consumption from the previous month, difference between consumption volume from the previous month,yearly average consumption,monthly volume deviation from the yearly average and a variety of other statistical data could be presented on the billing statement. In addition to Water Department staff,an outside computer programmer will prepare and incorporate the computer program into the current billing system The development of the computer program should begin immediately in order to be able to incorporate this information into the customer's billing statement as soon as possible. Development time is currently unknown and will depend on the scope of the presentation desired. Schedule: Start - 1995 Completion - Ongoing A one-time cost for development of the computer program to generate and present the billing history data would occur in 1995. Additional costs for providing this information are not expected but may occur depending on the scope of the presentation developed. Cost: = $8,500.00 -1995 only High Technology Meters The latest technological advance in telemetry and metering will be used to distinguish water use patterns. 10 The city has implemented these technologies by metering all customers and installing a sophisticated telemetry and supervisory control system to tie together the operation of all major facilities. A data logger is used at each facility to record flow rates. This information is utilized for system demand analyses. No additional cost is anticipated for this element of the water conservation program. Cost: = $0.00 Continue the operation of the telemetry and supervisory control system. Continue installation of meters for each customer. Schedule: Ongoing 11 POLICY Require Meters The City will require the installation of individual service or master source meters for all water uses, including public facilities. The city has implemented this policy by metering all customers and installing a data logger at each water facility to record flow rates. The Department of Operations and Maintenance currently tests and repairs these meters periodically. Continue requiring the installation of meters for all customers. Schedule: Ongoing No additional costs associated with this element of the water conservation program are anticipated. Costs: = $0.00 Plumbing Code The City will recommend revisions to the plumbing code that will be based on technologically advanced equipment and facilities that efficiently use water. The most significant plumbing code revisions will require water-efficient fixtures to be installed in all newly constructed or extensively remodeled buildings. Improved technologies that minimize leakage should be required as soon as economical and reliable equipment is developed. Cooperation with county and state officials will be instrumental in developing and adopting revisions to the code. The prompt recommendation for revision of the plumbing code should be pursued when the application of a new water conservation technology merits use. Schedule: Ongoing Costs associated with this element of the water conservation program would primarily be associated with administrative functions required to pursue revisions to the plumbing code. Costs: = $1,500/year Landscape Management/Playfields Policies will be developed that promote the application, development and management of low-water-demand • landscaping. 12 Regulation of landscaping based on water demand may become necessary to better manage the available water resources; however, strict control over landscaping of private, commercial, industrial and public land may not be necessary. Milder policies restricting water use for landscaping and limiting the water district's liability from plant loss due to dehydration should be enacted. Encouraging the use of low-demand landscaping features can be easily promoted by comparing costs of yard maintenance during a hypothetically dry year. — Cooperation with local nurseries is essential to ensure drought-resistant landscaping products are available for purchase by the public. Technical assistance provided to nurseries through other parts of this program will help strengthen this cooperation. The water demand created by grassy areas of public parks should be offset by the appropriate selection and efficient use of space for non-grassy areas. The benefits of rich,green grass in non-activity areas needs to be weighed against community's needs for an adequate water supply, especially during the summer dry period. Policies should be enacted as early as possible in order to cultivate public awareness of the water conservation efforts being implemented in the community. Schedule: Start - 1991 Completion - Ongoing Enactment of policies that regulate water demand for landscaped areas should not result in additional costs. Liability will be minimized if the policy also emphasizes the consequences of noncompliance. Costs: = $0.00 Seasonal Pricing/Inverted Rates Policies will be designed to provide incentives to conserve water based on the price of water. Seasonal pricing means that the unit price of water varies depending on the time of year: Higher rates would be charged during high-demand periods such as the summer months. Lower rates would be charged during low-demand periods. Inverted pricing means a customer is charged a specific price for an initial quantity of water. A higher price is charged for additional quantities of water, increasing as the quantities increase. Price variations can be developed that take into account the minimum requirements for a specified customer's demand,and increase the price dramatically for use above that minimum demand. Market pricing would vary the rate based on the demands on the system. If the availability of water was low, a considerably higher price would be charged for quantities over a minimum amount. High availability would result in lower rates. During the summer dry periods,the customer may see a reduction in rates as a result of significant water conservation. Obviously several pricing structures are possible. The effectiveness of each would require a further study in which the rate structure changes every year or two to survey the effectiveness of each policy. Prudence must be exercised in order to keep customer relations good. Costs and benefits must be emphasized to the customer throughout the program. The City should determine the effectiveness of varying rates for water use. A five-year survey period is recommended in order to have sufficient time to research the differences and take into account seasonal, water demand variations. At least two separate policies should be examined during this period. Further study may be desired if anticipated results are not achieved. 13 Schedule: Start - 1991 Completion - 1995 The direct cost for enacting any of these policies is difficult to quantify. Consequently,it is assumed that enacting policies to promote water conservation won't cost money. However, reductions in revenue may result from an effective conservation policy, or increases in revenue may result from an incentive policy that does not motivate conservation. Costs: = $0.00 Irrigation/Private Wells To better understand the availability of water resources within the city,private wells need to be identified. The location,aquifer source,average annual and peak month usage should be analyzed to evaluate the impact these wells have on the water resources available to the city. Policies must be developed to protect the interests of the community served by the district. Significant impacts may result from the operation of these private wells. A policy of limiting the caPaci tyof the wells would protect the community while allowing the private well owner to operate the well. Metering private wells would allow for better resource management and also promote efficient use of water. Changes in land use may make a private well available for city use. Significant legal implications may be involved with any policy that addresses this situation. Legal council should be advised prior to taking any action. Research on the implicationsof restrictive policies on private wells should also begin in order to be prepared for possible legal complications in the future. Schedule: Start - 1992 Completion - Ongoing after 1992 Costs for researching and identifying private wells may be small because it is assumed that much of the necessary information is a part of the City's current land use records. Costs:= $2,500/year I '. Utility Financed Retrofit The City will provide water-efficient fixtures for customers' residences, commercial and industrial facilities. This program element is similar to those that provide water conservation kits (Technical Assistance and Public Education sections). The decision to retrofit existing customers has the obvious advantage of assuring that reasonable efforts are being taken to reduce excessive use. Benefits include customer awareness and support. Several options for distributing these water-efficient fixtures are possible. Fixtures can be provided at no cost at the water utility's office,local hardware stores or other public facilities(i.e.schools,libraries,post offices,etc.). Rebates for customer purchases of water-efficient products that are approved but not provided by the utility would allow customers to choose the style of fixture. 14 The degree to which this program should be implemented is more a question of cost than necessity. An analysis of the cost savings as compared with the investment would have to be made. Cost: = $27,500/year • The majority of the costs associated with this element of the program will arise from the actual purchase and/or rebate for the water-efficient fixtures. The cost of each fixture depends on the quality and quantity provided. Rebates for selected items will also increase the overall costs. Some distribution costs can be expected,but they should not represent a large percentage of the total cost for this element. The financial analysis should occur before beginning this element of the water conservation program. If the analysis determines it is cost effective, water efficient fixtures should be provided as soon as possible to develop customer support and to receive water conservation benefits. Schedule: Start - 1992 Completion - Ongoing Master Source Meters A master source meter should be required,at a minimum,for Base Program utilities and would not apply to the city because of the size of the water utility. No action needs to be taken on this subject because it does not concern the city. Schedule: Start - 1991 Completion - Ongoing No cost is associated with this element of the water conservation program. Costs: = $0.00 15 ' Chapter Four PROGRAM EVALUATION AND IMPLEMENTATION Since this will be Renton's first direct involvement in a water conservation program, the program is modeled on conservation efforts in other areas in King County. In order to maximize the return on the invested conservation dollar, this program should be closely monitored and evaluated at the end of its first year of use. The goal of the evaluation will be twofold: first, to find out which projects and programs are effective, and second, to use that information in revising future efforts and planning for future conservation programs. Program evaluation will involve collecting data from objective and subjective measures of the program's effectiveness, analyzing it, monitoring 1 performance against projection,and measuring water savings. Evaluation using objective measures involves a variety of data collection activities. Project activity levels should be monitored and device-installation rates should be established through follow-up surveys of customers who receive kits. Data should be gathered to show actual,project-activity levels compared with projections made during the first year of the program. Subjective measures of program effectiveness will be important in evaluating the public cooperation program. The important factors to be considered include the audience reaction to programs, services and materials,and the staff's assessment of the effectiveness of various projects in changing customer attitudes and behaviors. By using both objective and subjective evaluation measures, the staff will be able to guide the evolution of the program during its first five years. The Water Conservation Program must be dynamic to further reduce water consumption,requiring frequent evaluation in an on-going process of program planning and development. 1 The most effective way to evaluate the different procedures would be to conduct different conservation campaigns in the three major hills,in the city,West Hill,Highlands,and Rolling Hills,and the Downtown area. The demands in these areas could be calculated independently,and their reduction in water consumption compared at the end of the program's first year. Assuming the reduction in demand in the different areas varies,the information could be used to emphasize the use of either device-oriented or education-oriented conservation procedures. PROGRAM IMPLEMENTATION The implementation plan for the 1991 to 1995 planning period divides the conservation tasks into three groups. 1. Continuous projects beginning in 1991 2. Phased projects 3. Continuous projects beginning after 1991. As discussed previously and in greater detail in Chapter 5, we recommend the isolated implementation of some of the conservation tasks in order to develop realistic data about the effectiveness of each program. The continuous projects remain in effect after they are started,but are not started simultaneously in all areas of the city. Projects that cannot be isolated geographically would start in later years to allow time to develop data on the other projects. In some circumstances, program tasks are similar and could be grouped together on the implementation schedule. Breaking these tasks into separate schedules would not provide additional meaningful data, since the target group and/or methods are similar. The following is a list of tasks that have common characteristics and should be included together for implementation purposes. GROUP 1 School outreach Speakers bureau Theme shows and fairs 1 GROUP 2 Program promotion GROUP 3 Single-family/Multi-family kits Plumbing code Utility financed retrofit GROUP 4 Purveyor assistance Technical studies Irrigation/private wells GROUP 5 Leak detection High technology meters Require meters Master source meters GROUP 6 Nurseries/Agriculture Landscape management GROUP 7 Seasonal pricing Bill showing consumption summary In general those tasks that generate immediate results should be implemented first. Consequently,the results of the tasks whose impact takes several years to measure are not attributed to other tasks that may have started in those subsequent years. In addition, the least expensive tasks should be implemented first to minimize the short-term, financial impacts on the city during a period when its Capital Improvement Program is aggressive. Groups 6 and 7 cannot be isolated and implemented on a geographical basis; they must be used system wide. It is recommended that they be implemented in later years to prevent them from masking the data collected from the other tasks. Some of the projects are not continuous,but involve research,study or one-time efforts that could be implemented throughout the planning period. Under some circumstances, such as a water shortage, implementation of this plan should be interrupted so that staff can react to the emergency. Using this criteria, the implementation schedule shown in Table 4-1 should be used. PROGRAM EVALUATION OF PHASED PROJECTS The different conservation campaigns should be evaluated using a three-phase plan. Phase one consists of developing demand data for each of the implementation areas of the city: West Hill, Highlands,Rolling Hills and Downtown 196 Zone. This should be performed in 1991 in order to identify demand per customer per month in each area. This data will be used in subsequent years to evaluate the conservation savings in each zone. Demand is calculated using records compiled by the Water System Data Logger. Each operating area includes the following zones and supply sources: Operating Area Zones Supply Sources West Hill West Hill 495 zone West Hill Pump Station West Hill 270 zone 2 Highlands Highlands 565 zone Mount Olivet Pump Station Highlands 435 zone Windsor Hills Pump Station Kennydale 320 zone Well 5 Rolling Hills Rolling Hills 590 zone North Talbot Pump Station Rolling Hills 490 zone South Talbot Pump Station Talbot Hill 350 zone Tiffany Park Pump Station Fred Nelson Pump Station Downtown 196 Downtown 196 zone Wells Nos. 1,2, 3, 8,9 Springbrook Springs The water pumped from each supply source should be recorded each month and tabulated. The number of customers in each operating area should be compiled from the billing department each month. The average demand per customer in each operating area is then calculated by dividing the supply to the operating area by the number of customers. Average demand is computed at the end of 1991 and used as the base line data for future observations and comparisons. { Phase two consists of implementing Group 3 tasks in the West Hill operating area,Group 1 tasks in the Highlands operating area,and Group 4 tasks in the Rolling Hills operating area. Demand data should continue to be compiled for each operating area. The costs to administer and implement each task should be recorded and compiled as detailed in Chapter 4. Phase three consists of comparing demand per area in 1991 with demand per area in 1992. The Downtown 196 zone can be used as a control set to cancel the possible effects of weather or other non-conservation influences,since there would be no conservation programs scheduled for this area in 1991 or 1992. Demand reductions in each area would then be combined with program costs to identify which program tasks are the most cost-effective. Future conservation tasks, programs, and program emphasis are then modified to reflect the most efficient conservation methods. 3 IMPLEMENTATION SCHEDULE TABLE 4-1 1991 1992 1993 1994 1995 1996 1997 GROUP 1 School Outreach Speakers Bureau Theme Shows and Fairs GROUP 2 - Program Promotion GROUP 3 - -- Family Kits Plumbing Code Utility Financed Retrofit GROUP 4 - Purveyor Assistance Technical Studies Irrigation/Private Wells GROUP 5 Leak Detection x High Technology meters Is.�:a�z..��s:...�,.0:,,:....�. .::>.,,.,...�w. � -<>:><<<:< ;;: <:<..,.,.,>:,>:g:.,.:::;.0_. ..>....... :....

The costs can be divided into two categories: personnel and equipment. The personnel costs will include the following additional staff hours to implement and monitor the conservation program: four hours per day in 1991 and eight hours per day in following years of a staff engineer; approximately two hours per week of the customer service or engineering manager's time for coordination and administration; periodic professional engineering services to update the plan,monitor the progress and effectiveness of the program elements and prepare community literature;maintenance personnel time to operate the leak-detection equipment;and. programming time to add consumption history to the billing program. A summary of these costs is shown in Table 5-1. The conservation program is an unbudgeted task in the city's 1991 budget; therefore, full deployment of the plan will not begin until fiscal 1992. Personnel costs have been assumed to inflate approximately 5 percent per year. Professional services costs are primarily for the creation of conservation literature and program materials. Equipment costs include a display board and project literature for the theme shows, water saving devices, leak detection equipment, and rebates for water-saving plumbing fixtures. Leak detection costs have been established by the maintenance department;they are estimated costs for checking 52 miles of pipe per year. At this inspection rate, each pipe in the system is checked every four years for leaks. The equipment costs for fixture rebates represent the approximate costs to retrofit 25 houses per year with water- saving toilets. Although the details for administering this program should be developed by the Water Department staff,it is assumed that households would apply for a rebate and the city would select approximately 25 houses per year for the rebate program. Houses would be chosen in the areas of Renton where water savings would provide the greatest benefit, such as the Highlands 565, West Hill 495, or Rolling Hills 590 zones. These zones are the highest in the city,and therefore are the most costly to supply with pumped water. Savings under this program could produce as much as .15 million gallons per day of water savings. In 1992 the program costs are expected to be 3.1 percent of the operating costs of the water utility and 1.99 percent of the total water department budget. COST BENEFIT ANALYSIS The success of this program can be measured in two ways. First,does the program maintain or improve the current 6 1/2 percent per capita reduction in 1987 demands, and second, are the reductions cost effective. Since the conservation program is mandatory,the cost effectiveness of the overall program is not as important as identifying which tasks or elements of the program are the most efficient. This will allow the program elements to be tailored to Renton customers and allow the targets to be realized at a minimum cost. The highest priority of the program's first five years should be evaluating the costs effectiveness of the tasks identified by the Department of Health. Currently,there is insufficient data to perform a cost-benefit analysis of each program element or task;however,it should be the highest priority of the conservation program to develop the data base necessary to do so. The data would be used in subsequent years to identify which tasks should be deleted,modified,or emphasized. 1 The necessary data base consists of two components: 1. Cost of each conservation task 2. Percent reduction in per capita use of each task A portion of a staff person's time should be dedicated to documenting how much time and how many resources are expended on each task. This information should be compiled every six months,at a minimum,to determine the cost of each conservation task. The six-month time frame is convenient to use since the city's budget and budget adjustment occur at six-month intervals. The six-month summaries will be easy to compile if staff people account for the time they work for the conservation program on separate time sheets. On the time sheets each conservation task should be divided into two categories,"Time"and"Materials," which should also include an estimate of the resources used for each task. The time sheet should also include a general administrative category for non-task specific activities, and later it should be divided equally into the cost of each conservation task. These time sheets would not be used by the personnel or accounting departments,but by the engineering staff who would use them to identify the cost of each conservation task and to perform a cost/benefit analysis. The second set of data needed to determine cost/benefit ratios is the effectiveness,or percent demand reduction of each conservation element. Three procedures can be used to determine task effectiveness: 1. Estimating 2. Isolated task application 3. Phased task implementation The first procedure consists of beginning all conservation tasks simultaneously in the entire service area. The effectiveness of each task is estimated by customer surveys and interviews,which would determine which tasks they believe benefitted them the most and which ones they remembered. This procedure results in the least reliable data, but is easy to administer and results in maximum conservation savings early in the program. The second procedure consists of applying selected tasks to each hydraulically independent section of the city. Because of Renton's comprehensive data logging system,it is possible to isolate demand in each of three hills of the water system (West Hill, Highlands, Rolling Hills). The city could, therefore, distribute devices on one hill, perform public education on another, and perform utility retrofits on the third. Each hill could be monitored independently the first year and an estimate made of the reduction potential of each program. This procedure is more difficult to administer,but results in more accurate data for the cost/benefit analysis. An inverted or seasonal pricing structure cannot use this procedure,since the entire service area must be billed uniformly. Some program tasks are not suited for this type of isolated application since the effects may inadvertently apply city-wide: seasonal pricing, modified bills,and nursery participation are examples of this situation. Other tasks, however,can be implemented on a geographical basis. The third procedure consists of applying a new task each year to the service area, and monitoring its effectiveness on a yearly basis. As an example, in 1991 only home kits would be distributed, in 1992 home kits and speakers would be used,and in 1993 home kits,speakers and seasonal pricing would be distributed. A potential disadvantage of this procedure is the difficulty in assigning cause and effect relationships in demand estimates. Are changes caused only by conservation,or by weather,new development character,etc.? Another potential disadvantage is the implied consent to delay some conservation tasks,rather than beginning a comprehensive and complete program immediately. It should be remembered,however,that Renton has achieved the 6 1/2 percent target,and,therefore, has the luxury of using 1991 through 1995 for task and program evaluation, an easy procedure to administer. We recommend the second procedure,Isolated Task Application,if Renton is able to devote considerable staff time to the Conservation Program. This task usefully combines responsible and timely implementation with accurate 2 data,but requires intensive time to administer. If Renton is unable to allocate the necessary hours,we recommend the first procedure,Estimating. This program complies with the intent of the Department of Health regulation and is easy to administer. Final analysis of the Cost/Benefit ratio should include all of the costs necessary to administer and implement each task of the conservation program and compare that cost with the estimated water savings produced by the task and expressed as: * Cost per gallon per connection per day. * RATE IMPACTS Table 5-1 is a summary of the program's projected costs for 1991 and 1992 and their impact on water system rates necessary to support this program. The total budgets shown in Table 5-1 are estimates based on the CIP program identified in the Comprehensive Water System Plan and based on the assumption that operation and maintenance costs will increase approximately 5 percent per year. Since these are estimates, actual rate impacts will differ, slightly. The average monthly customer cost to implement this Water Conservation Plan is as follows: 1992 - $ 0.33 1993 - $ 0.27 1994 - $ 0.26 1995 - $ 0.22 The effects of revenue reduction from the conservation plan are not included in these rate impacts, since there is no data to support the effect of each conservation task. For comparison purposes,the approximate yearly commodity cost to produce 1 percent of the city's water supply(not including fixed overhead and maintenance costs)is$4,400. The billing income for 1 percent of the supply is approximately$22,000 per year,resulting in a$ 1,466 per month loss for the Utility, or a rate impact of$0.13 per customer per 1 percent conservation savings. 3 TABLE 5-1 5-YEAR CONSERVATION COSTS 1991 1992 1993 1994 1995 1996 PERSONNEL COSTS School Outreach $0 $5,000 $5,250 $5,513 $5,788 $6,078 Speakers Bureau $0 $5,000 $5,250 $5,513 $5,788 $6,078 Program Promotion $0 0 $2,500 $2,625 $2,756 $2,894 Theme Shows/Fairs $0 $5,000 $5,250 $5,513 $5,788 $6,078 Family Kits $0 $1,500 $1,575 $1,654 $1,736 $1,823 Customer Assistance $0 $1000 $1 050 $1 103 $1 158 $1 216 Technical studies $0 $500 $525 $551 $579 $608 Leak Detection $0 $21,000 $22,050 $23,153 $24,310 $25,526 Nursuries/Agriculture $0 $0 $0 $2,500 $2,625 $2,756 Bill Showing History $0 $0 $0 $0 $8,500 $0 High Tech Meters $0 $0 $0 $0 $0 $0 Require Meters $0 $0 $0 $0 $0 $0 Plumbing Code $0 $1,500 $1,575 $1,654 $1,736 $1,823 Landscape Management $0 $0 $0 $0 $0 $0 Seasonal Pricing/Rates $0 $0 $0 $0 $0 $0 j Private Wells $0 $1,000 $1,050 $1,103 $1,158 $1,216 Utility Financed Retrofit $0 $2,500 $2,625 $2,756 $2,894 $3,039 Master Source Meters $0 $0 $0 $0 $0 $0 SUBTOTAL $0 $44,000 $48,700 $53,635 $64,817 $59,133 ' EQUIPMENT COSTS School Outreach $0 $0 $0 $0 $0 $0 Speakers Bureau $0 $0 $0 $0 $0 $0 Program Promotion $0 $0 $2,500 $2,500 $0 $2,500 Theme Shows/Fairs $0 $3,800 $0 $0 $2,500 $0 Family Kits $0 $4,500 $4,725 $4,961 $5,209 $5,470 Customer Assistance $0 $1,500 $0 $0 $0 $0 Technical studies $0 $2,000 $0 $0 $0 $0 Leak Detection $0 $0 $0 $0 • $0 $0 Nursuries/Agriculture $0 $0 $0 $10,000 $2,500 $2,625 Bill Showing History $0 $0 $0 $0 $0 $0 High Tech Meters $0 $0 $0 $0 0 $0 Require Meters $0 $0 $0 $0 $0 $0 Plumbing Code $0 $0 $0 $0 $0 $0 Landscape Management $0 $0 $0 $0 $0 ' $0 Seasonal Pricing/Rates $0 $0 $0 $0 $1,000 $0 Private Wells $0 $0 $0 $0 $0 $0 Utility Financed Retrofit $0 $25,000 $26,250 $27,563 $28,941 $30,388 Master Source Meters $0 $0 $0 $0 $Q $0 SUBTOTAL $0 $36,800 $33,475 $45,024 $40,150 $40,982 TOTAL $0 $80,800 $82,175 $98,659 $104,967 $100,115 ' • RATE IMPACTS Anticipated Utility&O&M Costs $2,608,000 $2,738,400 $2,875,320 $3,019,086 $3,170,040 Anticipated CIP Program Costs $2,035,000 $2,487,000 $3,134,000 $3,898,000 $4,849,500 Total Anticipated Costs $4,070,000 $4,974,000 $6,268,000 $7,796,000 $9,699,000 - Percentage of City Budget 0.00 1.99 1.65 1.57 1.35 - Average Cost Per Customer Per Month $0.00 $0.33 $0.27 $0.26 $0.22 - WATER CONSERVATION PLAN Appendix A Program Elements & Tasks From East King County Coordinated Water System Plan . h DEFINITION OF CONSERVATION ELEMENTS FOR PUBLIC WATER SYSTEMS For purposes of the recommended plan,program elements are defined as follows: A.

Technical Studies - Studies would be designed and conducted by the public water system and/or regional organization. Study objectives would be to collect data and research new technology to develop programs which would produce measurable water savings. Study areas might include residential flow metering, lawn watering practices, and commer- cial/industrial water use patterns. 4. Unaccounted Water/Leak Detection - Conduct a regular and systematic program of finding and repairing leaks in system mains and laterals. This includes on-site tests using computer-assisted leak detection equipment on water distribution mains,valves, services, and meters. 5. Nurseries/Agriculture - Apply current technology to water use practices of large agriculture/irrigation operations. Examples are nurseries and park department facilities. Moisture sensors, flow timers, low volume sprinklers, drip irrigation, and other practices to increase irrigation effi- ciency would be implemented. 6. Bill Showing Consumption History - An extension of the electric energy conservation program. Billings would show percentage increase/decrease in water use over the same period in the previous year. 7. High Technology Meters - Utilize concepts of telemetry and exception reporting to detect and investigate instances of abnormal water usage. C. POLICY 1. Require Meters - Require the installation of individual service and master source meters for all water use, including public facilities. Maintain periodic meter testing and repair program. 2. Plumbing Code - Develop recommendations for Code revisions to require water efficient fixtures for new construction and extensively remodelled buildings. Work with State officials for adoption. 3. Landscape Management/Playfields - Promote low water demand land- scaping in all retail customer classes (private, public, commercial, indus- trial, etc.). Work with local nurseries to ensure the availability of plants that achieve this objective. 4. Seasonal Pricing- Implement rate design techniques to provide economic incentives to conserve water. Under seasonal pricing, the unit price of water would be increased during a high seasonal use period. Rate setting is the responsibility of the public water system. -16- • 5. Irrigation/Private Wells - Identification of location, aquifer source, aver- age annual, and peak month usage to analyze impact on supply and eval- uate availability for public water system use where land use changes occur. General purpose government would be encouraged to monitor use and consider land use and building code conditions that would promote efficient use of water from these sources. All wells above a specified capacity should be required to be metered with use records available for resource management. 6. System Financed Retrofit - Under a program similar to that used in the electrical energy program, installation of water efficient fixtures in exist- ing residences and commercial/industrial facilities would be promoted by the system by: (a) providing fixtures at no cost, (b) giving a rebate for consumer purchased fixtures, and (c) arranging for suppliers to provide fixtures at the systems' cost. 7. Master Source Meters - Require a master source meter, at a minimum, for Base Program systems. D. MERITING CONSIDERATION 1. Mandatory Seasonal Restriction - Implement and enforce restrictions in water use during peak demand periods in all categories of consumers under an adopted strategy/plan. 2. Recycling/Reuse - Examine opportunities for water reuse and recycling as an approach to reducing water demands. Potential program areas include: o Reuse of reclaimed public water systems wastewater for the irriga- tion of public green space, industrial cooling, and power plant cooling. o On-site wastewater treatment and recycling of effluent for non- potable uses in commercial buildings. o Utilization of gray water (bath, lavatory, and clothes washing water) for non-potable uses. 3. No Water For Golf Courses/Major Use - In future siting of golf courses and other large water consuming facilities, or where the location of such existing facilities warrants, allow only the use of reclaimed wastewater. -17- f . 4. Conservation Program Performance Audit - To evaluate the efficiency and effectiveness of a system conservation program, an entity such as the Regional Water Association or the County shall routinely conduct a program performance audit and report its findings to the system. 5. Reduce Pressure to 45 psi - In service areas with excessive pressure (as determined by the system) require pressure reducing valves on service connections. -18- • CITY RENT..I • 4Y :.s ' 19, { I-11 CLERK'S OFFS • AFFIDAVIT OF PUBLICATION L e An n e Hutton ,being first duly sworn on oath states 5 0 6 4 0 that he/she is the Chief Clerk of the VALLEY DAILY NEWS • Kent Edition • Renton Edition • Auburn Edition Daily newspapers published six (6) times a week.

ORDINANCES OF THE CITY OF RENTON, WASHINGTON". BY ADDING A NEW SECTION RELATING TO CROSS CONNECTION CONTROL.. THE CITY COUNCIL OF THE CITY OF RENTON, WASHINGTON, DO ORDAIN AS FOLLOWS : SECTION I . Chapter 4, Water, of Title VIII (Health & Sanitation) , of Ordinance No. 4260 entitled "Code of General Ordinances of the City of Renton, Washington" is hereby amended by adding the following section: Section 8-4-45: CROSS CONNECTION CONTROL: A. . Purpose. National standards of safe drinking water have been established. The City of Renton, as a water purveyor, has the primary responsibility for preventing water from unapproved sources, or any other substances, from entering the public potable water system. This ordinance is to protect the health of the water consumer and the potability of the water in the distribution system. This is accomplished by eliminating or controlling all actual (direct) and potential (indirect) cross connections between potable and non-potable systems through the use of approved backflow prevention assemblies . ' B. Definitions . AIR GAP: A physical vertical separation through the free atmosphere sufficient to prevent backflow between the free flowing discharge end of the potable water system and the overflow 1 ORDINANCE NO. 4312 level of the receiving vessel, tank, plumbing fixture or any other system. Physically defined as a distance greater than or equal to twice the diameter of the supply pipe diameter, but in no case less than one inch. APPROVED: Approved in writing by the Department of Health or other agency having jurisdiction. ATMOSPHERIC VACUUM BREAKER: An assembly which prevents backsiphonage by creating an atmospheric vent when there is either a negative pressure or subatmospheric pressure in the water system. It is designed to protect against backsiphonage only. AUXILIARY SUPPLY: Any water source or system on or available to the ' premises other than the purveyor approved potable water supply. BACKFLOW: The flow of water or any other liquid, gas or substance from any source back into the distribution pipes of the potable water supply system. BACKPRESSURE: Backflow caused by a pump, elevated tank, boiler, or other means that could create pressure within the system greater than the potable water supply system. BACKSIPHONAGE : The flow of water or any other liquid, gases or substances from any source back into the distribution pipes of the potable water supply system caused by the reduction of pressure in the potable water supply system. BACKFLOW PREVENTER:. An approved assembly which prevents the backflow of water or any other liquid, gas , or 2 ORDINANCE NO. 4312 substance from any source back into the distribution pipes of the potable water supply system. BAROMETRIC LOOP : A fabricated piping arrangement rising at least thirty-five ( 35) feet at its topmost point above the highest fixture it supplies . It is used in water supply systems to protect against backsiphonage only. CONTAMINANT: A substance that will impair the quality of the water to a degree that it creates a serious health hazard. CROSS CONNECTION: Any physical or potential arrangement whereby a public water system is connected, directly or indirectly, with any other non-potable water system, drain, sewer, conduit, pool, storage reservoir, plumbing fixture, or other device which contains, or may contain, contaminated water, sewer, or other waste liquid of unknown or unsafe quality which may be capable of imparting contamination to the public water system as a result of backflow. Bypass arrangements, jumper connections, removable sections, swivel or change-over devices , ' or other temporary or permanent devices through which backflow may occur are considered to be cross connections . DOUBLE CHECK VALVE ASSEMBLY: An approved assembly composed of two single, independently acting check valves , either spring loaded or internally weighted, installed as a unit between two tightly closing shutoff valves and having suitable connections for testing. HEALTH HAZARD: A physical or toxic hazard which could be dangerous to health. 3 ORDINANCE NO. 4312 REDUCED PRESSURE PRINCIPLE BACKFLOW PREVENTER: An assembly consisting of two independently acting spring operated check valves , separated by a spring loaded differential piessure relief valve, which is installed as a unit between two tightly closing shutoff valves and having suitable connections for testing. POLLUTION: A hazard which could cause aesthetic problems or have a detrimental effect on the quality of water in the potable system. POTABLE WATER: Water which is safe for human consumption, as described by the public health authority having jurisdiction. PRESSURE VACUUM BREAKER: An assembly consisting of a spring loaded check valve and independently operating air inlet valve, inlet and discharge shutoff valve, and properly installed test cocks . The air inlet valve is internally loaded to the open position, normally by means of a spring. This internal loading allows the assembly to be installed on the pressure side of a shutoff valve. It is designed to protect against backsiphonage only. C. Application. This chapter applies throughout the water service area of the City of Renton. It applies to all systems installed prior to or after its enactment.

Item.6 a Councilman Stredicke requested that he be excused from Council Chambers Planning: Downtown during discussion of this matter due to a possible conflict of interest. Renton Association (DRA) Study Community Services Department and Planning/Building/Public Works Department submitted a request on behalf of the Downtown Renton Association (DRA) for a grant application in the amount of $25,000 in Washington State Local Development Matching Funds (LDMF) for a planning study of the City's downtown area. The City and the DRA will share the responsibility for the matching funds in the amount of $12,500 each. The City's match may be in the form of cash or staff support. Councilwoman Zimmerman disagreed with language in the draft which stated that the North Renton neighborhood is in transition and requested deletion of the comments. Community Services Administrator John Webley explained that the grant application and resolution must be submitted by October 5, 1990. The document will be finalized and distributed to Council by Friady, September 28. In response to Councilman Tanner's inquiry, Mr. Webley said that the City became the grant applicant because it was anticipated that the DRA would not complete incorporation by October 5; and since the City is acting as an agent, it will have more input in the development of plans for this project. Mr. Tanner said that Kirkland rejuvenated its downtown area as part of its comprehensive plan. The project was implemented by zoning ordinances and the capital improvement program, and was supported by a financial plan. Kirkland also incorporated a local downtown benefit district, and a tax was levied on businesses to ensure contribution by the recipients of the improvements. He noted that Auburn, Kent, and Burien have been through similar processes and suggested Renton consider this course of action.

Anderson, Utility Systems Division Manager SUBJECT: City of Renton, Comprehensive Water System Plan- 1990 ISSUE: The Water Utility has received the proposed Comprehensive Water System Plan from the consultant. We are submitting the Plan for review by the Council and to initiate the Council approval process. SUMMARY: 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. The plan is based on current policy, regulations and law adopted by Federal and State government, and the Renton City Council. The plan is divided into 4 sections: 1. Planning 2. Existing System 3• Future System 4. Improvements Comprehensive Water Plan September 13, 1990 Page 2 PLANNING: The City's service area population, amount of storage and land use trends are elements affecting water system planning. Population projections have a large impact on water supply planning, however, planned land use changes within the service area have a small impact. 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 vehicle. Service area boundaries will not change without annexation and amendment of the service area agreements with adjacent purveyors. 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. Most of Renton's northern neighbors are supplied by the City of Seattle, and are experiencing reductions in water resource allocations. On our eastern and southern boundaries, the populations are served, at least in part, from groundwater sources. It is not known if these sources will supplement Renton's water supply system, but the coordination of the development and protection of regional water resources will benefit Renton. A key to our planning is securing water rights to our aquifer. Water quality is high, however, our system is vulnerable to groundwater contamination. Water quality and supply reliability standards and policies have the largest impact in facility planning and phasing. In fact, water resource planning, acquisition, 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 distribution system has been designed to provide maximum day demands and adequate fire flow to all customers. However, by State Department of Health Standards, City. Policy, and engineering practice, the system is deficient in booster station capacity to the Highlands 435 and 565 pressure zones, and West Hill pressure zones, and is deficient in storage in all of the pressure zones except the West Hill. Therefore, the proposed CIP contains projects to meet these needs. FUTURE SYSTEM It appears that the City has an adequate source of supply from groundwater resources located within the existing service area. However, development of facilities to withdraw groundwater and applications for water rights should be pursued as soon as possible, since political and/or economic events may 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. It should be noted that the US Environmental Protection Agency (USEPA) is proposing numerous changes to water quality regulations that may impact the City of Renton Water Utility. Since these regulations have not been finalized, it is difficult to determine costs that may be associated with required improvements such as water treatment and operational changes. Therefore, the system improvements and budget outlined in the _ . .r Comprehensive Water Plan September 13, 1990 Page 3 Comprehensive Plan do not include provisions to accommodate improvements necessary to meet these proposed regulations. IMPROVEMENTS Future improvements identified in the Comprehensive Plan to meet reserve requirements and projected growth include: 12,750 gpm of additional well capacity 27,000 gpm of additional booster station capacity 26 million gallons of additional storage capacity New wells, pump stations, reservoirs and pipelines will need to be constructed to provide additional reserve, adequate fire protection, to replace asbestos cement and steel watermains, and to serve new customers It should be noted that service to new developments will be partially funded by the new fee structure being implemented by the City. Engineering investigations and groundwater management programs are necessary to assure compliance with Federal and State water quality standards and to use available water resources most effectively. The improvement plan is expected to require increases in Renton's water rates during the next 5 year period, as was previously reviewed and adopted by City Council action during the 1990 budget review process. The rate increases summarized in the Comprehensive Plan do not take into account possible improvements and operational modifications required by proposed additions to USEPA water quality regulations. SUMMARY The Comprehensive Plan is complete except for two sections that are currently being prepared: the Conservation Plan and the Cross Connection Control Program. These documents will be available for review and approval at a later date.
