Lead Free DC

Fill Out This Form to Start Your Replacement

Program Overview

Safe drinking water is our top priority and DC Water has taken significant steps to reduce lead in drinking water. Water is essentially lead-free when it leaves the water treatment facility and travels through DC Water’s distribution system and water mains in the street. Clean water can come in contact with lead as it flows through the service lines, pipes and plumbing in and around your home.

DC Water estimates the District of Columbia has more than 42,000 service lines with lead or galvanized-iron pipe. It is our goal to replace all of them with copper pipe.

DC Water launched the Lead Free DC Initiative in 2019 to accelerate lead service line replacement and combine all our lead reduction efforts under one banner.

The Lead Free DC fiscal year 2025 data and program updates report can be found here. If you are looking for service line replacement data, please review our public dashboard and historic service line replacement data.
