What is the Water Infrastructure Finance Authority?

WIFA is Arizona's Cleanwater and Drinking Water SRF administrator

Arizona's State Revolving Funds (SRFs) are the best choice for financing the design and construction of water and wastewater infrastructure projects. 

We operate as a "bond bank" and can issue water quality bonds for water infrastructure. Our diverse borrower portfolio and AAA credit rating allow us to pass the savings to our borrowers. WIFA never charges application fees, closing costs, or origination fees. All loans receive a discounted interest rate, lowering the borrower's interest costs to between 70 and 95% of WIFA's tax-exempt cost of borrowing.

We also manage a Technical Assistance Program (TAP), offering additional funding for eligible wastewater and drinking water systems as part of a loan application. TAP funds received by the borrower don't require repayment. They are there to help the borrower during project design, construction, or assist with compliance requirements.
