To amend the Federal Water Pollution Control Act to reauthorize sewer overflow and stormwater reuse municipal grants.

HR 5730 reauthorizes federal grants for municipalities to address sewer overflows and implement stormwater reuse projects. It allocates $350 million annually from fiscal years 2026 through 2031 to fund these infrastructure improvements. The bill directly affects cities and towns managing wastewater systems by providing dedicated funding for modernizing stormwater management and reducing pollution. This is a funding authorization, not a new program, focusing on concrete financial support for municipal environmental infrastructure projects.
