On June 29, 2026, EPA announced it will waive the $25,000 WIFIA application fee and the credit processing fee — averaging roughly $156,000 per loan — for communities of 25,000 or fewer residents in fiscal years 2026 and 2027. Combined, that removes nearly $200,000 in upfront cost from the single most affordable federal water-infrastructure financing program, which carries roughly $11 billion in available capacity and can cover up to 80% of eligible project costs at Treasury-rate pricing. For small towns, rural utilities, and the nonprofits and districts that serve them, this is a rare instance of the federal government lowering the barrier to a program that has historically been out of reach for exactly the communities that need it most. Here is what changed, who qualifies, and how to move on a letter of interest before the window closes.
Read articleFor FY2026 and FY2027, EPA is waiving the $25,000 WIFIA application fee and the ~$156,000 credit-processing fee for water systems serving 25,000 or fewer people — a near-$200,000 discount on access to an $11 billion pool of low-cost federal financing. The waiver removes the single barrier that kept small and rural utilities out of WIFIA for a decade. Here is how WIFIA actually works, who qualifies, why the letter of interest is the real gate, and how a town of 8,000 should think about a program built for billion-dollar projects.
Read articleFor FY2026 and FY2027, EPA is waiving the WIFIA application and credit-processing fees for communities of 25,000 or fewer — saving nearly $200,000 per loan — against roughly $11 billion in flexible financing that covers up to 80 percent of project costs. Here is why WIFIA has been underused by small systems, how the loan actually works, and how a rural utility should build a WIFIA strategy in 2026.
