In partnership with Gold Ridge Resource Conservation District (GRRCD), Sonoma Resource Conservation District (Sonoma RCD), Daily Acts, County of Sonoma and the California Department of Water Resources, rebates are available for rainwater harvesting systems installed anywhere in Sonoma County. Rebates will be provided for both small and large rainwater capture systems, based on a limited-time, first-come, first-served basis. This program is designed to reduce the barriers to installation by increasing the affordability of these systems and providing technical assistance for system design, installation, and troubleshooting.

1 – Rebate Varies by Location:

City of Healdsburg

Up to $0.50 per gallon of storage, not to exceed actual cost. Total rebates for rain barrels and cisterns may not exceed $500 per site.

City of Santa Rosa

Up to $0.50/gallon of storage, not to exceed the cost of materials.

Bodega/Salmon Creek Watershed

The Department of Fish and Wildlife has provided limited funding specific to residents in the Salmon Creek watershed whose water use has impacts on streamflow in the Salmon Creek mainstem and its tributaries, including those using riparian pumps, near-channel shallow wells, or members of the Bodega Water Company system. 

The program will offer free design assistance and a rebate of $0.50/gallon up to $5,000 towards the cost of materials for rainwater catchment installation, and also provide up to two 5,000-gallon HDPE tanks to design recipients who are moving forward with system construction.  Program participants will be required to sign an agreement with DFW and GRRCD, stating that they recognize the water stored by the system is meant to offset summer water uses that may impact streamflow. 

Potential applicants not willing to sign an agreement are still welcome to apply to the county-wide program, which still provides design assistance and rebate funding but does not include tanks.

If you have any questions please reach out to Noelle with Gold Ridge Resource Conservation District, noelle@goldridgercd.org

All other areas of Sonoma County – Systems under 5,000 gallons

Small rainwater storage capacity less than 5,000 gallons will receive $0.50 per gallon.

Rebate funding remains for systems under 5,000 gallons but is being quickly allocated, and cannot be guaranteed.  If you haven’t started construction of your system, please contact moreinfo@dailyacts.org to see if adequate funding remains.

Note that small systems are meant to be Do-It-Yourself. Please review the rainwater rebate kick-off webinar, along with the posted FAQ and other resources before filling out the application for technical assistance below.

If you have any questions please reach out to Daily Acts, moreinfo@dailyacts.org

All other areas of Sonoma County – Systems 5,000 gallons or more

Large storage capacity, 5,000 gallons or more may receive $.50 per gallon up to $5,000. 

Designs must be developed or approved by program staff before construction to ensure they comply with necessary specifications.  Once designs are approved, rebate funding is earmarked to allow the applicant six months to complete construction before submitting their documentation.

Due to the popularity of the program, many landowners have completed designs and all current funding has been earmarked.  As not all program applicants will move forward with construction, we anticipate rebate funding will still be available for new applicants, but can no longer guarantee a rebate to new applicants.  However, we encourage everyone interested in a system to move forward with the design process, as we are actively seeking more grant funding to continue the rebate program.
