Verification, Replacement & Funding

One of the main goals with our What’s Your Pipe Type? Program is to help customers verify their water service line pipe material. A water service line is the pipe that carries water from WSSC Water’s water main to your property. We have developed a user-friendly inventory map where you can type in your address to see your pipe material and complete a survey that will assist in our pipe verification efforts. If we verify that your water service line material contains lead, WSSC Water strongly recommends replacing this line. We plan to begin replacing lead service lines in 2025, ahead of the EPA requirement of 2027. Our goal is to complete all lead service line replacements by the EPA requirement date of 2037.  

We will prioritize verification and replacement efforts based on several criteria, including: schools/daycare facilities, properties with children/pregnant women, and properties in disadvantaged communities. If your water service line is verified as lead and you plan to replace the portion that you own (customer side), please notify us as the EPA requires that we replace the utility-owned water service line.  

We are also developing a financial assistance program to aid in the cost of replacing the customer-owned portion of the water service line and will post more information on this page once plans are finalized.
