Rates & Regulations
San Jose Water's rates are set by an independent third party, the California Public Utilities Commission (CPUC). The CPUC's mission is to protect utility customers and ensure the rates charged by all utilities are fair and reasonable. The water rates charged by San Jose Water are based on "cost of service," which means we pass through our operating costs without a markup.
