The Bill Calculator provides a bill estimate based on your assumed household water usage and property characteristics. Bill amounts are reported for the current rates (effective July 1, 2025) and for the proposed rate adjustments for the next two fiscal years (effective July 1, 2026, and July 1, 2027). The proposed rates are to be considered by the SFPUC Commission in a rate hearing on April 28, 2026. Learn more about the proposed rates and the upcoming rate hearing.
