Low-Income Household Water Assistance Program Establishment Act

This bill establishes a federal program to help low-income households pay for drinking water and wastewater services. It provides $500 million annually (2026-2030) in grants to states and tribes that already administer energy assistance programs, allowing them to cover past-due bills or other costs for households meeting specific income criteria (e.g., receiving certain federal benefits or earning ≤150% of the poverty level). The program prohibits using these funds to replace existing assistance and requires technical help to streamline eligibility. It directly affects low-income households in participating states and tribes, particularly those facing water affordability challenges.
