Landscapes can soak up more than 50% of the water used at a typical San Diego home. Capturing rain from your roof is a quick way to conserve water and help prevent pollution by reducing the amount of runoff entering our storm drain system. Then, use your catch to help irrigate your landscape.

City of San Diego Public Utilities residential customers can receive a cash-back rebate when purchasing and installing a rain barrel and connecting it to the home's rain gutter downspout. Read the guidelines below to understand the program requirements and application process. Rebates will be distributed on a first-come, first served basis and funding is limited.

Additionally, information on and a link to SoCal Water$mart's separate rain barrel rebate program is included below. City of San Diego water customers may qualify for both rebates.

General Information About Rain Barrels

What are Rain Barrels and how do they work?

Rain barrels are used to collect rainwater from hard surfaces such as rooftops. When you install a rain barrel at your home you are helping to maintain a healthy urban watershed by reducing the demand on the potable water system to irrigate your garden, and by reducing the amount of wet weather runoff that is collected and sent into the public storm water system, which goes untreated into our bays and estuaries.

How much water do Rain Barrels save?

The amount of water that can be collected from a rooftop depends on several variables, including the dimensions of the rooftop, the collection capacity, and the amount and timing of the rain received. Be sure to do some calculations to determine how much rain barrel storage capacity you need. Remember, San Diego typically receives around ten inches of rain annually.

Rainwater catchment rule of thumb:

1,000 square feet of roof surface captures
625 gallons of water for every
1 inch of rain that falls.
