Limited-Income Gray Water Loan & Grant Program

Interested in collecting wastewater from your hand-washing sinks, showers, bathtubs and clothes washing machines to water your backyard plants and trees? Our Limited-Income Gray Water Program seeks to increase the participation of limited-income households in Tucson Water’s Gray Water Rebate Program. Many limited-income households cannot afford the upfront costs to install gray water irrigation systems. With funding from Tucson Water, our program provides a grant of up to $200 and a 0-interest loan of up to $1,000 for your household to pay for the systems over time and qualify for Tucson Water’s rebate. If you obtain a loan, you must make a deposit of $20.00 or 10% of its value (the higher amount will be applied). Most loans are for 12 months. A permit will be required to modify drainage plumbing/piping from any fixture. A permit will not be required to use a pre-existing gravity stub-out from the washing machine.
