Why It Matters
A new CRS report on federal water infrastructure programs examines the Trump administration's proposed fiscal year 2027 budget cuts and their collision with decades of unmet infrastructure needs, proposing steep reductions to programs that have long underpinned American water systems.
The nation faces a combined 20-year need for wastewater and drinking water infrastructure exceeding $1.2 trillion, yet the budget would slash core funding mechanisms by roughly 79 percent for the Clean Water State Revolving Fund and 63 percent for the Drinking Water State Revolving Fund, calculated against the elevated Infrastructure Investment and Jobs Act (IIJA) funding levels of $2.603 billion annually through 2026 for each revolving fund.
These cuts threaten to reverse gains made by the 2021 Infrastructure Investment and Jobs Act, which supplied those baseline amounts, plus targeted one-time investments, including $3.0 billion for lead service line replacement and $800 million for emerging contaminants.
Congress rejected similar proposals last year, but the administration's renewed assault on these programs signals a fundamental shift in federal responsibility away from Washington and toward states and localities already stretched thin.
The Big Picture
The Trump administration's fiscal year 2027 budget proposal aims to return funding for the State Revolving Fund to levels before the Bipartisan Infrastructure Law was enacted in 2021, explicitly encouraging states to assume greater responsibility for financing their own water infrastructure needs.
Beyond the revolving funds, the budget eliminates or drastically curtails dozens of programs. For example, the Water Infrastructure Finance and Innovation Act (WIFIA) program would receive only $7.8 million for administrative expenses with no new credit assistance, a sharp reduction from the current $72 million in subsidy costs that enables approximately $6.5 billion in credit assistance. The HUD Community Development Block Grant program would be eliminated entirely, and the Economic Development Administration would be shut down with just $20 million for orderly closeout. The administration would also eliminate discretionary funding for the USDA Watershed and Flood Prevention Operations, though $150 million in mandatory funding would remain.
The scope extends to specialized initiatives. The administration's fiscal year 2027 budget request proposes eliminating funding for Water Infrastructure Improvements for the Nation (WIIN) Act Water Storage Projects (fiscal year 2026: $62.5 million); Title XVI water reuse projects (fiscal year 2026: $13 million); and desalination research and development (fiscal year 2026: $6.7 million).
Western water projects face particular pressure from the administration's fiscal year 2027 budget proposals, with threats to slow water recycling in California; to reduce rural water support in Wyoming, New Mexico, and Utah; and to limit desalination expansion in Arizona and California.
Most programs would see reductions, though EPA's Small Water System Resilience grants would rise from $6.5 million to $16.5 million, a modest increase that does not offset the broader retrenchment across the federal water infrastructure portfolio.
The Bottom Line
EPA's 2022 Clean Watersheds Needs Survey estimates an additional $630.1 billion is needed over the next 20 years for projects eligible for the Clean Water State Revolving Fund (CWSRF).
Congress enacted fiscal year 2026 appropriations that rejected many of the administration's proposed cuts, funding the Clean Water State Revolving Fund at $746 million and the Community Development Block Grant at $3.3 billion.
The administration's fiscal year 2027 budget proposal represents a significant departure from this bipartisan consensus.
