Capture Rain to Save Water

Did you know that one inch of rain falling on a 1,000 square foot roof could result in 600 gallons of water stored for future use? Collecting and reusing rainwater is a great way to water trees and shrubs during dry spells. Rainwater harvesting also reduces stormwater runoff which can help reduce flooding during rainstorm events.

Rebates are available to Sonoma County residents for a limited-time, on a first-come, first-served basis through a simple application process and proof of installation. Learn more

Rainwater harvesting rebates are also available in Marin County. If you live in Novato or West Marin, learn more from North Marin Water District. If you live in Central or South Marin, learn more from Marin Water.


The Partnership was formed to identify and recommend implementation of water use efficiency projects, and maximize the cost effectiveness of water-use efficiency programs in our region.
