PWSA Lead Service Line Map

PWSA is in the process of performing Curb Box Inspections throughout the City of Pittsburgh and Millvale to determine which water service lines are made of lead pipe. We are also digitizing our historical paper service line records. The map below shows the results of curb box inspections as well as available paper records for properties within our water service area.

Please note many of the historical records are from when the property was originally constructed and are no longer accurate. The map will be updated as more data is available.

The portion of the water service line that is public and owned by PWSA runs from the water main in the street to the “curb stop” (water service shutoff valves, usually located in the sidewalk between the water main and the building). The remainder of the line that connects from the curb stop to the building is considered private property.

This searchable interactive map indicates the results where inspections have already occurred around the city and where PWSA plans to replace lead service lines in 2018:
