City of Sonoma Water Supply and Distribution System
Sonoma’s primary source of water is from the Russian River, supplied by the Sonoma County Water Agency (Water Agency). The Water Agency pumps water that is naturally filtered through rock, sand and gravel from wells about 100 feet below the river bed and transports that water down Sonoma Valley in an underground aqueduct. The City has seven deep wells that supplement the purchased water supply. These wells are an important source of local water supply that would be vital in an emergency that disrupts the flow of water from the aqueduct. Water distribution facilities owned by the City include four storage tanks, two booster stations, and the necessary water mains and appurtenances for purveying water within the service area. The City is also connected to two storage tanks owned by the Water Agency. The City of Sonoma Water Division strives to provide the following services for the community and its citizens:
- To supply safe and reliable drinking water in accordance with California and Federal Regulations.
- To supply water at reasonable rates consistent with cost-effective conservation.
- To maintain sufficient water pressure in the drinking water system to ensure successful fire protection.
- To provide water to critical facilities.
