Water Supply Development Revolving Fund

The Water Supply Development Fund (WSDF) was established in 2007 with HB 2692 and aimed to help areas of Arizona lacking access to sufficient water supplies and in need of financial assistance to construct projects necessary to obtain additional water supplies.

In 2021, through SB1823, the Arizona Legislature allocated $40 million to the WSDRF (press release), opening more financial opportunities for Arizona’s rural water providers to improve their water infrastructure projects.
