S. 5577 — A bill to amend the Federal Water Pollution Control Act to provide grants to upgrade or convert small-capacity cesspools for households in the State of Hawaii.

This section authorizes grants to the State of Hawaii or responsible management entities to cover 75 percent of the cost of converting small-capacity cesspools serving single-family residences to individual wastewater systems, connecting them to treatment works, or converting communities of such cesspools to cluster or decentralized systems, as well as related workforce development and technical assistance. It authorizes $20 million annually for fiscal years 2028 through 2032, with up to 2 percent available for administrative expenses, and directs the Administrator to prioritize projects posing the greatest risk to human and environmental health.
