Arizona Water Rebates
Tucson, Arizona Water Rebates
Tucson Water offers a rebate for residential customers who install rainwater harvesting systems - cisterns and tanks that collect and store roof runoff for landscape irrigation. The rebate is $0.25 per gallon of storage capacity for systems between 50 and 799 gallons, and $1.00 per gallon for systems of 800 gallons or more, up to a maximum of $2,000 per property. You must attend a class and submit an application before purchasing or installing the system.
Common steps for every program in this guide
- Attend a required Tucson Water rainwater harvesting class. Complete a qualifying class through Tucson Water or the Watershed Management Group before applying. Classes cover system sizing, design, first-flush diverters, and code requirements. Check watershedmg.org/rebate-classes for the current schedule.
- Submit your online application and project plan to Tucson Water. After completing the class, submit the online rebate application and a project plan at the Tucson Water rebate page. Do not purchase equipment or begin installation until Tucson Water reviews your application. Your property must have active Tucson Water service.
- Purchase and install the rainwater harvesting system. After receiving application approval, purchase and install the cistern or tank as described in your approved project plan. Systems must be 50 gallons or larger. First-flush diverters are recommended and may be required by local code for in-ground tanks.
- Submit completion documentation and receive your rebate. After installation, submit proof of purchase (receipts) and photographs of the completed system to Tucson Water. The rebate is calculated at $0.25/gallon for 50–799 gallon systems or $1.00/gallon for 800+ gallon systems, with a $2,000 maximum.
