How Should Wastewater Utilities Navigate The Looming Federal Funding Cliff?

Water and wastewater utilities have likely been fretting over a rapidly approaching date: September 30, 2026.

For the past few years, the water sector has been enjoying a wave of federal investment, courtesy of the Infrastructure Investment and Jobs Act (IIJA), also known as the Bipartisan Infrastructure Law. The bill poured $55 billion into the nation’s water systems. But this money is set to expire soon.

Now utilities are staring down what industry advocates call the IIJA funding cliff. Unless Congress passes new legislation, federal supplemental funding for the State Revolving Funds (SRFs) is scheduled to expire, sending available assistance back to pre-2021 levels.

The Drop’s Impacts Are Widespread

To understand what this means for local capital improvement plans, utilities must look at the numbers. While the IIJA felt massive, groups like the National Association of Clean Water Agencies (NACWA) note it actually addressed only about 5% of the estimated $1.2 trillion national water infrastructure gap.

When the clock runs out in September, the drop-off will be sharp. For example, a recent impact report by the Environmental Policy Innovation Center (EPIC) modeled state-level impacts and showed that, without further congressional action, states like Nebraska are bracing for an estimated 77% decline in federal SRF funding. Even worse, if legislative earmarks continue to divert the remaining base funds into non-revolving grants, that drop could deepen to over 90% in some regions. Every single state faces a significant reduction.

This comes at a time when utility cost pressures are already high. Roughly 30% of utility executives surveyed by the AWWA report struggling just to recover basic operating costs due to inflation, energy prices, and supply chain constraints.

Strategic Moves To Make Right Now

While many utilities may want to hold out on planning and scheduling new projects in hopes of a last-minute extension or “soft landing” funding, such delays carry risk. After all, modernization projects doesn’t pause an asset’s aging. Pumping and aeration account for up to 60% of a typical wastewater plant's energy footprint. Running inefficient, decades-old blowers while waiting out a political funding cycle simply burns operational cash that could otherwise offset a tighter capital budget.

As such, utilities should act fast to take advantage of whatever money is left. This means shifting from a reactive posture to an aggressive optimization strategy. Water professionals should be looking at a few key levers to shield their operations:

1. Lock in current-cycle allotments. The remaining FY2026 IIJA funding tranches are moving through state agencies now. Getting applications finalized and projects “shovel-ready” today is the most reliable way to capture the last of the historic federal match.
2. Leverage alternative financing structures. While SRFs are the default path, the Water Infrastructure Finance and Innovation Act (WIFIA) program remains a powerful tool. The EPA has closed more than 150 WIFIA loans, providing billions in long-term, low-interest financing for larger regional projects while saving utilities significant capital over traditional municipal bonds.
3. Prioritize operational efficiency (ROI-driven capital). When capital dollars are scarce, infrastructure investments must pay for themselves. Modernizing a treatment process with high-efficiency equipment—such as smart aeration controls, dissolved oxygen pacing, and advanced positive displacement or turbo blowers—directly slashes the monthly energy bill. That immediate drop in operational expenditure (OpEx) frees up internal cash flow to fund future capital projects (CapEx) when federal grants dry up.

The funding landscape is changing, but the regulatory mandates and infrastructure realities are not. Utilities that act aggressively to lock in the remaining IIJA dollars—and focus their remaining capital on projects that cut long-term operational costs—will be the ones that weather the drop without disrupting their communities.
