Water rates pay for ongoing operations, maintenance, repair and improvements of the City’s water utility. Costs include the purchase of water plus operation and maintenance of wells, water mains, fire hydrants, valves, meters, pumps and other infrastructure. Rates also pay for capital improvement projects to upgrade water pipes and other infrastructure to ensure the City can continue to serve safe and reliable water into the future. The City purchases about 90% of its water from the Sonoma County Water Agency (SCWA) to serve residential, commercial and irrigation customers.
