Limited-Income Rainwater Harvesting Loan & Grant Program

Interested in collecting rainwater on your property to help water your plants, shade your home, cool urban temperatures, grow your garden, and increase biodiversity in Tucson? If so, rainwater harvesting would be a great option for you to look into. These systems, although very beneficial and cost-saving over time, can have an expensive upfront cost that isn’t realistic for limited-income families. However, with Tucson Water’s rebate program and additional funding, rainwater harvesting is an attainable possibility for limited-income households. Our program provides access to grants and zero-interest loans that help participating families qualify for the Tucson Water rebate, as well as providing households with the option to pay for these systems over time.

Qualifying participants can receive a passive system and/or an active system. The full rebate amount that can be received if the system is sized to capture at least one inch of rainwater from the drainage area will receive $1/gallon for active systems and $1.50/gallon for passive. If a system is not sized large enough to capture the full one inch of rainfall, the customer will receive $0.50/gal for all system features.

Tucson Water is enacting a new rebate process and rebate amounts beginning on July 1, 2023. With this new rebate process, Tucson Water has an increased involvement; SERI’s program process can be seen below.

Trees and Shrubs for Participants

Participants in our Limited-Income Rainwater Harvesting Loan & Grant Program as of February 1st, 2022 can order up to two trees and two shrubs to help increase tree canopy at their home and in their neighborhood. With funding from Tucson Water and City of Tucson we are able to provide participants with trees and shrubs for free.

We partner with nurseries in Tucson to provide participants with a selection of trees and shrubs that are drought tolerant desert adaptive. When participants order their trees and shrubs through our program, they will receive educational material on planting and maintenance.
