Community Assistance Program (CAP)

Our Community Assistance Program (CAP) service discount offers qualifying residential single-family customers a 15% discount on water and a 35% discount on sewer charges.

CAP applicants and re-enrollments will now be required to participate in a free water conservation home evaluation. Our Water-Wise Evaluation program is facilitated by a trained water conservation specialist and can lower your bill even more! Each ‘site-specific’ visit will provide free showerheads and faucet aerators, if needed, help detect costly plumbing leaks and show you ways to conserve our great Hetch Hetchy drinking water.


  • The water and sewer bill must be in your name.
  • You must be a full time resident at the address where the discount will be received.
  • You must only have one water service account with the SFPUC.
  • You may not be claimed as a dependent on another person’s tax return.
  • You must pay your bills by the due date.
  • Your total combined household gross income must not exceed the CAP Income Guidelines.
  • Your total annual bills must not exceed 5% of your total combined gross income.
  • You must participate in a Water-Wise Evaluation to be enrolled in the program.
  • Your water use should not exceed the acceptable range of daily water use per household occupant as determined by the SFPUC.
  • You must provide access to all water-using areas/fixtures on the property including any basement areas, in-law units, and landscaped areas at the time of Water-Wise Evaluation.
  • You agree that if a water leak occurs at your residence, you will make timely repairs.
  • You must notify the SFPUC immediately if your household no longer qualifies for the discount.
  • You must renew your complete eligibility application every two years.

Water-Wise evaluations are available for existing CAP customers upon request. However, new CAP applicants should not schedule the home evaluation prior to receiving a letter stating your household meets the program requirements. To schedule the evaluation, please call (415) 551-4790.

Helping Families in Need Save Water and Money!

With California facing tough economic times and another year of drought, you can help a family in need and help conserve our precious drinking water by making a contribution to CAP today. Your contribution to CAP will help provide less fortunate San Francisco families with a short-term discount on their water/wastewater bills. Once enrolled, CAP families will then receive free, direct installation of low-flow fixtures and water-efficient toilets in their homes that will dramatically reduce their water use, replacing the need for a direct subsidy with lower water/wastewater bills for the long-term. Look for the line on the detachable portion of your water bill to make a donation.
