|County Service Area 41 Water Systems (CSA)
The County of Sonoma Board of Supervisors governs four water systems referred to as Zone of Benefit. These four zones consist of Fitch Mountain, Freestone, Jenner and Salmon Creek. The water systems are supervised by the Department of Transportation and Public Works, with billing services provided by the County Auditor. Operation, maintenance, engineering, management, meter reading and emergency repairs are the responsibility of RRU. Remote radio telemetry system monitors both the Fitch Mountain and Jenner systems, which provide 24-hour alarm reporting systems.
Fitch Mountain Water System
This system serves 346 customers. The water supply is purchased from the City of Healdsburg. This water is pumped into three 100,000-gallon storage tanks for distribution to three pressure zones. A pneumatic pressure system provides water to the highest zone on McDonough Heights Road. Russian River Utility monitors and controls this system with a remote radio telemetry system.
Freestone Water System
This system consists of 28 services. The water supply consists of a surface water spring and three ground water wells. All water is oxidized to remove dissolved iron and filtered in a multimedia pressure filter.
Jenner Water System
This system serves 123 customers. The water supply consists of surface water pumped from Jenner Creek. This raw water is treated in a multimedia gravity filter treatment plant. This plant is monitored by a remote telemetry system which transmits turbidity, disinfectant residual, and tank level to the RRU office in Forestville. Treated and disinfected water is stored in a 100,000-gallon tank. Russian River Utility monitors and controls this system with a remote radio telemetry system.
Salmon Creek Water System
This system serves 99 customers. The water supply consists of two separate sources: a shallow ground water well with an elevated specific conductivity, and a spring galley source under the influence of ground water. Both sources are disinfected with liquid chlorine.
Two booster pumps supply the distribution system and a high volume pump is available for fire flows. A generator is available to insure water delivery in the event of a power failure.
