The City of Santa Rosa provides water to over 161,000 individuals in our service area and another 15,000 in the unincorporated areas of Sonoma County adjacent to the City. The City’s water distribution system includes 630 miles of pipe, 25 enclosed reservoirs (water tanks) which store 27.5 million gallons of water, 20 pump stations and a system of pressure regulation valves to provide a constant supply of water to our 53,747 connections. The water delivered from the Sonoma County Water Agency (SCWA) aqueduct provides pressure to the lower elevations of the City. Storage reservoirs in elevated locations, primarily on Santa Rosa’s east side, are filled by the pump stations, allowing gravity to provide water pressure to the rest of the City service area.
