Water and Sewer Bill Calculator
This calculator is a guideline. For more information on current water and sewer rates, visit Water and Sewer Rate Information. For more information on how to read your bill, visit Reading Your Bill.
Before you use the calculator tool:
- Have a recent water and sewer bill nearby to reference while using the calculator
- Look up your property’s measured permeable and impermeable areas on the Stormwater Charge Lookup website.*
*In San Francisco, the typical non-residential property is 95% impermeable. If you are a residential customer, please note that most residential properties fall within the 1,701 - 3,300 square feet range and will not need to provide impermeable and permeable areas.
