The Water Supply Development Revolving Fund (WSDRF) was created to provide low-cost financing, grants, and technical assistance for water supply development projects outside of Arizona’s major urban centers. This fund is specifically designed to meet the unique water supply needs of small, rural communities.  


WIFA can provide up to $2 million in grant funding and up to $3 million in the form of a low-interest loan for a total of $5 million in financial assistance per application.   


Interest rate discounts and grant eligibility will be determined based on the criteria listed in ARS § 49-1274(B)(3), including:

  • Water Demands: existing, near-term and long-term water demands compared to the volume and reliability of existing water supplies
  • Project Benefits: impact on water supply, benefits to multiple jurisdictions, conservation efforts, BMPs being implemented, and long-term reliability of supply being developed
  • Project Feasibility: engineering specs, the cost and effectiveness of the proposal, funding sources, and public comment
  • Financial Need: median household income

Eligible Entities:

Water providers and political subdivisions located outside of the Phoenix, Tucson, or Pinal AMAs.
