WATER SYSTEM MASTER PLAN 2. DESCRIPTION OF EXISTING WATER SYSTEM

This chapter describes the District’s system. It contains a description of the service area and its climate, and the water supply facilities, including the groundwater wells, surface water supply facilities, booster pumping stations, reservoirs, and the piping system.

2.1 Description of Service Area The District serves a population of approximately 160,000 in Sacramento County. Within the District are four service areas: the North Service Area (NSA), the Arbors at Antelope, McClellan Business Park, and the South Service Area (SSA). The term NSA is also used to describe a larger area consisting of the Arbors at Antelope housing area, McClellan Business Park, and the previously mentioned NSA. The SSA includes the Town and Country service area of the former Arcade Water District. Figure 2-1 illustrates the location of the District and the neighboring water agencies. The service areas within the District are shown on Figure 2-2. Subareas within the service areas were created in this plan to further analyze the distribution system. The subareas within the District are shown on Figure 2-3.

2.2 Water Supply Facilities Water supply for the District is currently derived from active groundwater wells and surface water from Placer County Water Agency (PCWA) via Folsom Reservoir and San Juan Water District’s (SJWD) Peterson Water Treatment Plant (WTP) and from the American River via the City of Sacramento’s Fairbairn WTP. This section describes the District’s wells and surface water facilities. Figure 2-4 depicts the locations of the water system facilities. The Area D place of use boundary (for the City of Sacramento supply) and the PCWA Water Rights place of use are also shown on this figure. The McClellan Business Park water system facilities are also described in Appendix A. The water system is monitored and operated automatically using a Wonderware/Tesco Controls SCADA system. Almost two-thirds of active wells are connected to the SCADA system, as well as most of the reservoirs and booster pump stations. The District’s SCADA system consists of three major components: remote site controls, radio communications, and the SCADA master station. A more detailed description and evaluation of the SCADA system is presented in Appendix B.

2.2.1 Groundwater Facilities Groundwater has been the primary source of water for both the NSA and SSA. The District’s groundwater supply infrastructure has a total groundwater pumping capacity of 98,390 gallons per minute (gpm) from 89 active wells. This includes new well N36 Verner (1,500 gpm) which is scheduled to be placed into operation in 2009. All of the wells pump directly into the distribution system. The larger NSA contains 42 active wells with a combined capacity of 49,195 gpm. Within the SSA there are 47 active wells with a combined capacity of 49,195 gpm. Figure 2-5 provides an illustration of the well capacities.

2: Description of Existing Water System

Water System Master Plan

Tables 2-1 and 2-2 summarize the capacity and characteristics of the active and inactive wells in the District. The term “active” is used to refer to wells that are fully operational and used for water supply within the District. Wells throughout the District are generally between 200 and 1,300 feet deep and draw water primarily from the Mehrten formation. The older, shallower wells typically produce up to 1,000 gpm. Some of the newer wells produce over 2,500 gpm. Table 2-1. North Service Area Wells Well no. 15 16 27

2.2.2 Surface Water Facilities The District imports surface water from three supply sources. The District’s current surface water agreements are with PCWA, City of Sacramento, and the United States Bureau of Reclamation (USBR) (Section 215 Central Valley Project (CVP) water). Surface water from PCWA and the USBR is diverted from Folsom Lake and treatment is provided by the Sydney N. Peterson WTP. The Peterson WTP is owned and operated by SJWD. SJWD also supplies treated surface water from Folsom Reservoir for a family of water entities (SJWD Retail Service Area, Orange Vale Water Company, Citrus Heights Water District, City of Folsom-Ashland Area, and Fair Oaks Water District [FOWD]). The Peterson WTP has a nominal capacity of 120 million gallons per day (MGD). Treated water is pumped to the Hinkle Reservoir, which has 62 million gallons (MG) of storage capacity. From the Hinkle Reservoir, the potable surface water supply for the District is delivered by gravity flow through the San Juan Cooperative Transmission Pipeline (CTP) followed by the Antelope Conveyance Pipeline (ACP) (formerly referred to as the Northridge Conveyance Pipeline). The 48-inch diameter, gravity flow ACP is constructed from the terminus of the San Juan Cooperative Transmission Pipeline at C-Bar-C Park, which is located on Oak Avenue, east of Sunrise Boulevard within the Citrus Heights Water District service area. The District owns the total pipeline capacity of 59.2 MGD in the ACP and that same quantity of flow in the larger capacity CTP. The surface water facilities are illustrated on Figure 2-4.

2: Description of Existing Water System

Water System Master Plan

The District has a surface water supply from the American River through a contract with the City of Sacramento, dating to 1964. Historically, only a portion of this amount has been diverted through the American River Well Field located in the SSA. The American River Well Field is not currently being used because it does not meet the requirements of the Surface Water Treatment Rule. In 2006, the District began receiving surface water from the City of Sacramento. This water is treated at the City’s Fairbairn WTP and delivered to the District via the City’s Howe Avenue transmission main to an existing interconnection located near Enterprise Drive and Northrop Avenue in the SSA.

2.3 Distribution System This section discusses the District’s distribution system, including storage, pump stations, and interconnections. The District has four service areas: NSA, SSA, McClellan Business Park, and Arbors at Antelope. Frequently in this plan the McClellan Business Park and Arbors at Antelope service areas are included as part of the larger NSA. Within the larger NSA there are two pressure zones: larger NSA (includes McClellan Business Park and Arbors at Antelope) and the North Highlands subzone. The North Highlands subzone is hydraulically separated from the rest of the NSA by a pressure reducing valve (PRV) located at Bainbridge Drive and Walerga Road. While McClellan Business Park and Arbors at Antelope are separate service areas, they are not hydraulically separated pressure zones. There is no PRV between Arbors at Antelope and the NSA. Water from the NSA to McClellan Business Park flows directly into the McClellan Business Park service area (boosters from the NSA to McClellan Business Park are rarely used). Water is served to McClellan Business Park but prevented from flowing back into the NSA. Because of fluoridation and surface water place of use restrictions in the SSA, the SSA is hydraulically separated from the NSA (by closing main line valves) and is its own pressure zone. A hydraulic schematic of the distribution system is shown on Figure 2-6.

2.3.1 Pipelines The distribution system ranges in size from 48-inch mains down to 4-inch laterals. Table 2-3 provides a breakdown of the linear feet of each pipe diameter in the system. Pipeline material consists predominantly of asbestos cement, polyvinyl chloride (PVC), ductile iron, mortar lined coated steel, and cast iron pipe. Table 2-4 provides a breakdown in linear feet of the pipe materials in the system. The District’s standards include the requirement for gridding cross connecting mains at intervals of approximately 1,300 feet with a minimum size of 12-inch. Exceptions have been made where 10-inch mains and larger exist in the grid pattern.

2.3.2 Storage Facilities The NSA has four active storage tanks. A five MG storage tank and booster pumping station, located at the Antelope reservoir site, stores both groundwater from nearby wells and treated water from the Peterson WTP to meet peak hour demands and fire flows. The maximum pumping capacity from the Antelope reservoir is approximately 10,000 gpm. Another five MG capacity groundwater storage reservoir and 10,000 gpm booster pump station is located near the intersection of Watt Avenue and Elkhorn Boulevard in the North Highlands service area. There is a 150,000 gallon elevated storage tank located in the Arbors at Antelope area and a 125,000 gallon elevated storage tank located at the District’s Walnut Corporation Yard. There are two active elevated storage tanks in the McClellan Business Park service area. The SSA has one active storage tank which was recently constructed in 2006. It is a five MG storage tank and booster pumping station located at Enterprise Drive and Northrop Avenue. The reservoir storage and pump stations are summarized in Table 2-5 and depicted on Figure 2-4. The reservoir storage and pump station capacity is summarized in Table 2-5 and depicted on Figure 2-4. Detailed descriptions of each storage and booster facility are provided below. Table 2-5. Storage and Pump Stations Name

2: Description of Existing Water System

Water System Master Plan

Antelope ground reservoir and BPS – The Antelope ground reservoir was constructed in 1997 and is

located in the northeast corner of the NSA. The NSA surface water supply from the Peterson WTP is delivered via the CTP to the Antelope facility. Capehart elevated reservoir – The Capehart elevated reservoir is located in the Arbors at Antelope service area, previously owned by the federal government. This tank was constructed in the 1950’s. The District has operational issues with utilizing this storage tank because the height of the tank is lower than the HGL of the service area. The current service area pressures range from high 70s psi to low 80s psi. Watt/Elkhorn ground reservoir and BPS – The Watt/Elkhorn ground reservoir and booster pump station

(BPS) is located in the North Highlands sub zone of the NSA. It was constructed in 2001. During peak demand periods the District has difficulties filling this tank and providing supply to meet demands. Well 31A is located near the reservoir and is plumbed to pump to the distribution system or the reservoir. McClellan Business Park elevated tank #769 – The McClellan Business Park elevated tank #769 is located

on the west side of the McClellan Business Park service area. It was constructed in 1952. The elevation of this tank is lower than the current HGL of the service area and the District has difficulty emptying this tank. McClellan Business Park elevated tank #216 – The McClellan Business Park elevated tank #216 is located

at Peacekeeper Way and Dudley Blvd. It was constructed in 1953. The elevation of this tank is lower than the current HGL of the service area and the District has difficulty emptying this tank. Walnut Yard elevated tank – The Walnut Yard elevated tank is located in the NSA near Walnut Avenue and

Auburn Blvd. It was constructed in 1958. Because the elevation of this tank is higher than the HGL of the NSA, the District utilizes a booster pump to boost water back into the tank from the system. As pressure drops in the system an operational control valve will slowly open to allow the tank to provide supply to the system. Enterprise/Northrop reservoir and BPS – The Enterprise/Northrop reservoir and BPS was constructed in

2006 and is located in the southwest corner of the SSA on Enterprise Drive (near the intersection with Northrop Avenue) at the City of Sacramento intertie.

2.3.3 Booster Pump Stations There are two booster pump stations that are designed to boost water from the District’s NSA into the McClellan Business Park service area. These booster pump stations are identical in configuration. The design flows for each booster pump station is shown in Table 2-6. The location of these booster pump stations are shown on Figure 2-4. These BPSs were constructed in 1988. Backflow prevention valves are located at both BPSs to prevent flow within the McClellan Business Park service area from re-entering the NSA. As demand increases and the pressure decreases, the booster pumps start and maintain the elevation at the set point. Because the pressure gradient for the McClellan Business Park service area does not differ significantly from the NSA, the booster pump stations rarely are required to operate, and sufficient flow is usually delivered by gravity.
