Water Authority staff is using the age of the house along with a visual inspection of the service lines connected to the water meter to determine what type of pipe is present at each property.  This process started in 2019 and will continue until the inventory is complete. 

You can search by address on the GIS Water Service Line Inventory Map to see what type of pipe, if any, is listed for your property.  If the pipe material is listed as unknown, please visually check the water line coming into your house and let us know what you find.  You will find tips on identifying pipe material and a form where you can report your results on the pipe material page.

Pipe material is defined as:

Lead:  Pipe that contains lead.
Non-Lead:  Pipe that does not contain lead.  This may include cast iron, PVC, copper or galvanized metal that is not downstream of lead pipe.
Galvanized Requiring Replacement:  Galvanized iron pipe that is downstream of pipe containing lead.
Unknown:  Material not yet identified.  Please inspect your pipe and let us know what type of material you find.

Locate where your water service line enters your house.

Your drinking water enters your home through a pipe the connects the water meter to your home's plumbing in your basement (if you have one) or a utility closet where your water heater and/or washing machine are located.

If you don't' know where your water enters your house, find the water meter located in your property next to the road.  The meter is covered by a metal or plastic cover. Typically the water line will follow a straight line from that meter to your house.  If you have a basement, look for the water line where it comes through the exterior wall closest to the location of your meter.  If you don't have a basement, your water line will enter your house where your water heater and/or washing machine are located.
