UPGRADE Act of 2025

This bill amends the Safe Drinking Water Act to extend support for small water systems and underserved communities. It updates technical assistance deadlines for small public water systems from 2026 to 2031 (Section 1442(e)(5)) and expands eligibility for assistance to include "unincorporated communities" identified by states with county coordination (Section 1459A). The changes directly affect small water systems and communities lacking municipal status, particularly in rural or disadvantaged areas. The bill provides longer-term funding certainty and broadens access to federal resources for water infrastructure improvements.
