For five years, federal infrastructure money roughly quadrupled what states could lend and grant for water and sewer projects. That era ended quietly on September 30, when the 2021 infrastructure law’s supplemental funding for the State Revolving Funds expired, and the numbers behind what comes next deserve every watershed group’s attention.
The Infrastructure Investment and Jobs Act put $43.4 billion of supplemental money into the Clean Water and Drinking Water State Revolving Funds from 2022 through 2026. That authorization lapsed September 30, 2026. A new Pew Charitable Trusts analysis warns that grants and principal forgiveness for disadvantaged communities will shrink first, and industry analysts project total federal water funding could fall about 60 percent from fiscal 2026 to fiscal 2027. Utility and contractor groups are pressing Congress to reauthorize the funds.
What just expired
The State Revolving Funds are the quiet workhorses of American water finance. Federal capitalization grants flow to the states, which lend the money at low or no interest to water and sewer systems, and repayments revolve back out to the next project. In Pennsylvania that machinery runs through PENNVEST; West Virginia and Ohio have their own versions. The infrastructure law supercharged it: in fiscal 2026 alone, the supplemental funding added $2.6 billion each to the clean water and drinking water funds, plus $3 billion for lead service line replacement and more than $1 billion for emerging contaminants like PFAS. The regular appropriations underneath were modest by comparison, about $746 million and $411 million.
Who feels it first
Pew’s October 14 analysis points out that federal dollars were only about 4 percent of total public water spending even at the peak, but they were the 4 percent that reached the places private capital will not go. The infrastructure law required states to push extra grants and principal forgiveness to disadvantaged communities, which is how a lot of small systems in coal country ever got to the front of the line. With the supplement gone, states fall back on standard loans, which are exactly what struggling systems cannot repay. The National Utility Contractors Association warns that when the support drops off, existing water and sewer work stalls, and groups like the National Association of Clean Water Agencies are urging Congress toward full reauthorization.
The projected drop in total federal water infrastructure funding from fiscal 2026 to fiscal 2027, according to industry analysts cited by Water Finance and Management.
The gap underneath
The hard part is that the five-year surge covered about 5 percent of the documented need. EPA’s own surveys put drinking water and wastewater needs around $1.2 trillion over 20 years, and utility association estimates run higher still. Pew projects that if systems lean on rates alone, more than a fifth of American households could be paying over 2.5 percent of their income for water by 2050. Readers who saw our piece last week on Pennsylvania water bills rising 62 percent in a decade already know which direction that pressure pushes.
Why it matters for the rest of us
Most H2O partner communities are small systems in a basin with old pipes, legacy pollution, and thin rate bases. The SRF supplement was the rare program that reached them on terms they could survive, and its expiration is a policy choice Congress can still revisit. This is a good season to tell your representatives, your county commissioners, and your utility boards what that money built here, while the examples are still fresh enough to point at.
