Single Family Residential Gray Water Rebate Program

Fact: 1/3 of typical household wastewater can be re-used as gray water for landscape plants.

Tucson Water's Single Family Residential Gray Water Rebate Program will reimburse you up to $1,000 when a permanent gray water irrigation system is installed in your home.

Gray water is wastewater collected from the drains of hand-washing sinks, showers, bathtubs and clothes washing machines. This water can be used to irrigate fruit trees, landscapes and lawns.

Alternative Water Source Irrigation System & Backflow Prevention Requirements

Use of an irrigation system that is pressurized with any kind of pump must have a reduced pressure principle assembly (RPA) installed at the service connection to protect the public water system from potential contamination. For more information on backflow assembly requirements for alternative water sources (rainwater and gray water irrigation systems), download the "Rainwater and Gray Water Irrigation Systems" brochure pdf, visit the Backflow Prevention web page, or call (520) 791-2650.

Gray Water Rebate Seminars are held at the Pima County Cooperative Extension, 4210 N. Campbell Ave., Tucson. Call (520) 626-5161 for information.
