Water & 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. View the Water Reuse Tour Program videos.

The following options are to make it as convenient as possible to manage your utility account during this time.
