Lead Service Line Inventory

Interstate Engineering has been appointed to conduct the inventory for some communities.

Materials Verification Test

A service line is a portion of pipe that connects the water main to the building. To find out if you have copper, lead, galvanized steel, or plastic service on your property, you can perform a material verification test on the water service line where it connects to the water meter to determine of the service line.

You will need a house key or coin and a magnet

Find the water meter on your property, typically in the basement, mechanical room, or in a wall panel.

Look for the pipe that comes through the outside wall and into the meter.

Use a key or coin to gently scratch the pipe to expose the color of the metal. Be careful not to puncture the pipe. If the pipe is painted, use sandpaper to expose the metal first.
