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.
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.
Applicants must submit a W-9 form form for rebates $600 or more, which are subject to tax, and will be issued a 1099-MISC for miscellaneous income. The W-9 form requires submitting your social security number.

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 , visit the Backflow Prevention web page, or call 520-791-2650 .
Rebate funds are limited and will be distributed on a first come, first served basis.
