Lead Line Replacement Programs

Burham lslr

PWSA will complete targeted lead service lines replacements with a prioritization model that removes lead in drinking water for our most vulnerable populations. 

Lead Service Line Replacement Approaches

Neighborhood Lead Line Replacement Projects: We target all lead lines in a geographic space, passing over non-lead service lines. When a private service line is made of lead, we will work with the property owner to replace the line at no direct cost.

Water main + lead service line replacement: This annual program targets aging water mains that also show high concentrations of lead lines attached. You can read more about this program on our Water Main Replacement Program page.

We have also replaced lead lines at all daycare facilities within our water service area as part of our Priority Lead Line Replacement program in 2022.

How is a service line replaced?

Crews will start the process by going to each property and inspecting the service line material at every property. This will help determine which sites have lead service lines that need replaced. 

If both a private and public lead service line is found at a property, the PWSA Lead Help Desk will reach out and set a coordination meeting with the property owner to discuss the replacement methods and schedule a replacement date. If a customer has a public lead service line, it will be replaced at no cost and no coordinate meeting is needed.

The next step of the process is to replace the lead service line with a non-lead material. We request that the property owner or a designated representative be present on this day. We will provide a lead pitcher filter and cartridges, as well as flushing instructions, after replacement. 

The final step of the project is restoration of streets and sidewalks. You can expect a delay between the completion of your service line replacement and restoration activities.
