Sonoma County Water Agency’s River Diversion Structure Modernization Project

Sonoma County Water Agency’s (Sonoma Water) River Diversion Structure (RDS) facility was originally constructed in 1975 to divert water from the Russian River into a series of infiltration ponds that recharge the alluvial aquifer that feeds collectors 3, 4, and 5. The RDS’ primary pumping, electrical, and control equipment has reached the end of its useful life and requires replacement. The Project will install upgrades to the facility such as medium voltage step-down transformer; motor control center; three vertical turbine pumps, facility lighting; heating, ventilation, and air conditioning; and a programmable logic controller that will improve the reliability of the water transmission system by replacing aging infrastructure with resilient and redundant equipment. The controls for the system will be modernized to allow for additional data to be collected that will be used to improve efficiency and operations.
