Financing Lead Out of Water Act of 2025

S 2007 (Financing Lead Out of Water Act of 2025) modifies federal tax rules to help communities replace lead pipes in drinking water systems. It clarifies that using tax-exempt bonds to replace privately-owned lead service lines connected to public water systems does not count as "private business use" under tax law, making these bonds eligible for tax exemption. This directly affects public water systems and the communities they serve, particularly those needing to comply with federal lead regulations. The key change allows municipalities to finance lead pipe replacement projects using tax-exempt bonds without violating existing tax code restrictions. The bill applies to bonds issued after December 31, 2025.
