The Detroit Water and Sewerage Department (DWSD) estimates there are more than 80,000 lead service lines delivering water to homes in Detroit. In the city of Detroit, lead service lines are most likely to be found in single-family homes built before 1945.
The water leaving the treatment plants that serve the city of Detroit does not contain lead, but lead can be released into drinking water from corrosion in lead service lines and household plumbing that contains lead. The water provided to DWSD customers contains a corrosion inhibitor to reduce corrosion of lead and other pipe materials into drinking water. If present, elevated levels of lead can cause serious health and developmental problems, especially for pregnant women and young children. Since 2018, DWSD has been working to verify lead service lines and replace them as part of the Asset Management Program.
As the Detroit Water & Sewerage Department (DWSD) continues to update our Verified Service Line Inventory records for the City of Detroit, we are also seeking grant funding for additional lead service line replacements, and your assistance in the verification process can be helpful to both you and your neighbors. DWSD continues to replace the existing lead service lines – the pipe providing water to a home from the water main – while on the same block as the water main replacement project. When your block comes up on the schedule, or if a grant funding is awarded to DWSD to perform individual lead service line replacement, we will notify you. Please note that completing this verification form does not guarantee DWSD will be able to replace your lead service line in the near future as that is dependent upon funding resources.
Before you complete the verification form, follow this online tool created by NPR to determine if you have a lead service line. During these steps, please take a photo of your service line taken near your basement wall or floor where the pipe enters your home to then upload when you submit the DWSD verification form.
