To amend the Federal Water Pollution Control Act to make certain technology investments eligible for additional subsidization, and for other purposes.

HR 5513 amends the Federal Water Pollution Control Act to expand eligibility for federal subsidies to include specific technology investments by water infrastructure projects. It directly affects water treatment facilities and municipal water systems seeking funding for upgrades. The bill adds software for asset management, operational analysis, and digital construction systems to qualify for subsidies when used to achieve water-efficiency, energy-efficiency, stormwater runoff mitigation, or cost-effective sustainable projects. This change modifies existing subsidy rules to include these digital tools as eligible for funding under the Act.
