IIJA's extra water funding has run out, and contractors want Congress to replace it

The supplemental water funding created by the Infrastructure Investment and Jobs Act (IIJA) has come to an end. The law's five-year authorisation and its extra money for the State Revolving Funds (SRFs) expired on 30 September 2026, and the National Utility Contractors Association (NUCA) is now lobbying Congress to reauthorise the programmes, Water Finance & Management reported on 12 October.

What has lapsed

Over its five years the IIJA added more than $43 billion to the SRFs, split between general capitalisation, lead service line replacement and emerging contaminants. In FY26 alone, the supplemental tranche included $2.603 billion each for the Clean Water and Drinking Water SRFs, $3 billion for lead line replacement, and $800 million (drinking water) plus $225 million (clean water) for emerging contaminants.

By comparison, regular FY26 appropriations put roughly $746 million into Clean Water SRF capitalisation grants and $411 million into the Drinking Water SRF. Without a replacement for the IIJA money, analysts cited by the publication warn that total federal water funding could drop by about 60% between FY26 and FY27. Congressionally directed spending of $1.6 billion does not refill the revolving funds, so it does not fill the gap.

What contractors are asking for

NUCA wants a multi-year reauthorisation of the Clean Water SRF, the Drinking Water SRF and the WIFIA loan programme at levels that keep up the IIJA's investment, backed by appropriations. It is also pushing for highway programmes that expired on the same date, a deadline the National Association of Counties had flagged in August as a funding cliff for FY27.

"Utility contractors can only bid what owners are able to fund," Zack Perconti, Chief Advocacy Officer, NUCA

What still flows

This is not an immediate stop. IIJA money already awarded keeps moving through project pipelines, and EPA has around $6.5 billion available in its current WIFIA financing round. What shrinks is new supplemental capacity. The longer-term need has not changed: EPA puts water and wastewater capital needs at more than $1.25 trillion over 20 years.

Why it matters for pipe

The SRFs have supported 76,000 projects since they were created, according to EPA, and municipal water and sewer work is a core market for HDPE pressure pipe, fabrication and fusion services. In our reading, a smaller federal pot from FY27 would show up first as thinner bid lists for 2027. NUCA's point is a simple one: contractors, and the suppliers behind them, can only chase the work that utilities can pay for.
