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. Visit the Backflow Prevention web page or call (520) 791-2650 for more information on backflow installation requirements for the use of Alternative Water Sources; Rainwater Harvesters and gray water systems equipped with pumps.
