The Onsite Water Reuse Grant Program helps support customer efforts to implement sustainable water practices in San Francisco and offset SFPUC water use. The collection, treatment and use of alternate water sources for onsite applications helps diversify our water supply, making us more resilient for the future.
Our Onsite Water Reuse Grant Program provides grant funding to encourage retail water users to reduce SFPUC water supply usage by collecting, treating, and using alternate water sources including rainwater, stormwater, graywater, foundation drainage, air conditioning condensate, and blackwater for non-potable uses such as toilet flushing, irrigation, and cooling tower makeup. Grant funding is available for three types of projects:
- Projects that are installing Onsite Water Systems on a voluntary basis (Voluntary Projects);
- Projects that are installing Onsite Water Systems on a mandatory basis in compliance with the Nonpotable Water Ordinance that go above and beyond Baseline NPO Compliance (Above and Beyond Projects); and
- Projects that are installing onsite treatment and reuse of brewery process water.
The SFPUC is seeking proposals for projects that meet one of the following criteria:1
- Projects that replace at least 450,000 gallons of SFPUC water per year are eligible for grant funding up to $200,000; or
- Projects that replace at least 1,000,000 gallons of SFPUC water per year are eligible for grant funding up to $500,000; or
- Projects that replace at least 3,000,000 gallons of SFPUC water per year are eligible for grant funding up to $1,000,000.
1For Above and Beyond Projects, the estimated SFPUC Water Offset must be achieved above and beyond Baseline NPO Compliance to be eligible for grant funding.
Note: Onsite Water Reuse Grant rules are currently being revised and will be posted here when they become available.
Grant applications are accepted on a rolling basis.
We anticipate funding multiple projects during this solicitation round. Provision of grant funding is based on the eligibility of the proposed project and availability of funds. Each application will be reviewed and evaluated on a case-by-case basis. Grant funding is available on a first come, first served basis. With the exception of Above and Beyond Projects, grant funding will not be provided to projects that are undertaken to comply with a City and County of San Francisco ordinance, including but not limited to the Non-potable Water Ordinance, codified in the San Francisco Health Code at Article 12C.
