The Lead-Free DC Omnibus Amendment Act of 2025 mandates the complete replacement of all lead service lines in the District of Columbia by December 31, 2030, prohibiting partial replacements and the installation of new lead, brass, or galvanized steel service lines. Property owners with lead service lines are required to enroll in the Lead Service Line Replacement Program or replace the lines themselves by October 1, 2024. The bill establishes protocols for testing service lines, public education initiatives, and prioritizes replacements for vulnerable facilities. It also requires the Department of Energy and Environment to engage community organizations for oversight and sets penalties for non-compliance.

Additionally, the bill mandates that the District of Columbia Water and Sewer Authority (DC Water) implement a comprehensive Lead Service Line Replacement Program at no cost to property owners, maintain an inventory of service lines, and provide water filtration devices to affected properties. It emphasizes public education on lead exposure risks, particularly for vulnerable populations, and requires regular reporting on the progress of replacements. The legislation also establishes a nonlapsing Lead Service Line Priority Replacement Assistance Fund and repeals certain sections of existing law to streamline the replacement process.
