Water and Sewer Services

Water and Sewer operations are financed and operated in a manner similar to private business enterprise where the intent of the governing body is for the costs (including depreciation) of providing water and sewer services to the general public on a continuing basis to be financed or recovered through user charges.

Water: The City owns and operates a public drinking water system consisting of pipelines, wells, pumps and tanks and is regulated by the State Water Resources Control Board Division of Drinking Water.

Sewer: The City owns and operates a public sewer collection system and sends wastewater to the City of Santa Rosa’s Regional Wastewater Treatment Plant for treatment and reuse. Click here for the Water Reuse Tour Program videos: https://srcity.org/1052/Water-Reuse.
