The Water Infrastructure Modernization Act of 2025 updates federal water pollution control law to support modernization of aging water infrastructure through grants for alternative water sources and smart water technology. The bill expands eligible uses of grant funding to include "intelligent water infrastructure technology"—such as real-time monitoring systems, artificial intelligence tools, leak detection technology, and advanced metering systems—that help water utilities operate more efficiently and reliably. Specifically, the legislation allows grant money to be used for implementing these smart technologies alongside traditional engineering and construction work, while explicitly prohibiting their use for routine operation and maintenance costs. The bill increases annual grant program funding from $25 million to $50 million and extends the program's authorization through 2028, and it requires the Environmental Protection Agency to report to Congress within 180 days and annually thereafter on funded projects, their outcomes, and recommendations for improvement.
