PWSA is in the process of performing Curb Box Inspections throughout the City of Pittsburgh to determine which water service lines are made of lead pipe. 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.
