Rainwater Harvesting Project Financing Options

Everyone should be able to harvest rainwater at home!
We Collaborate with Sonoran Environmental Research Institute to offer Grants and Loans!
Work with WMG’s expert designers and project managers to design and install a rain garden or tanks that work for you, within your budget, through our Co-op program.

Plant the water before you plant your plants. WMG works with Sonoran Environmental Research Institute (SERI) to assist you in receiving a rainwater harvesting rebate from Tucson Water. You can get up to $2,000 rebated through Tucson Water and an additional $500 or $750 grant from SERI. Remaining project expenses can be covered through the up-to $2,000 interest-free water harvesting loan option with SERI. 

For households who qualify, we provide a $50 on-site consultation with our expert designers (normally valued at $375) and discount our rain garden and rain tank installation workshops through the Co-op program.

Please review the household income chart to determine your eligibility for this program
