With the Infrastructure Investment and Jobs Act supplemental five-year water infrastructure funding set to expire Sept. 30, local government and water stakeholders are urging federal lawmakers to reauthorize core water programs and fully fund water infrastructure programs in fiscal year 2027. The 2021 IIJA allocated $50 billion for water infrastructure over five years, divided across five pots under the Clean Water State Revolving Fund and the Drinking Water State Revolving Fund, with specific funding to replace lead pipes and address PFAS and other contaminants. The National League of Cities is asking Congress to maintain the IIJA’s authorization amount — $5.85 billion each to the Clean Water State Revolving Fund and the Drinking Water SRF — and reauthorize grant and technical assistance programs to address PFAS, lead pipes and other water infrastructure projects in FY27. “Reauthorizing those programs is one of our top priorities,” Carolyn Berndt, legislative director, sustainability, told ESG Dive sister publication Smart Cities Dive. “It’s a critical time because we believe the committees are developing this legislation now.” While the House Appropriations Committee has begun advancing FY27 spending bills, including measures addressing transportation infrastructure funding that also expires Sept. 30, Congress has not yet introduced major legislation to reauthorize Environmental Protection Agency programs such as the Clean Water and Drinking Water state revolving funds, PFAS grant programs, lead service line replacement programs and other IIJA-funded water programs that expire Sept. 30, she said. Wastewater and stormwater systems will need $630 billion, and drinking water systems will need $625 billion over the next 20 years to keep up with infrastructure maintenance and comply with federal laws, according to Environmental Protection Agency reports from 2024 and 2023, respectively. But President Donald Trump’s FY27 budget request proposes cutting Clean Water and Drinking Water SRFs from $2.7 billion in FY26 to $305
