Single Family Residential Gray Water Rebate Program

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 receiving rebates for $600 or more will be issued a 1099-MISC exiting Tucson Water website for miscellaneous income.
