Water Service Lines

Service Line Inventory

The Village of Granville has determined that the probability of any lead services serving its customers is unlikely.

Nonetheless as part of the EPA’s newly Revised Lead and Copper Rule, EVERY water utility across the country is required to inventory all of its water service lines both on the public side and the private side.  WE NEED YOUR HELP complying with this mandate. 

Determining the Material of your Water Service Line

You will need a:
• Key or Coin
• Strong Refrigerator Magnet

Step by Step Instructions

1. Find the water service line in your basement. Look at the pipe that comes through the outside wall of your home.

2.  Carefully scratch the pipe (like you would a lottery ticket) with a key or coin.  Do not use a knife or other sharp tool.  If the pipe is painted, use sandpaper to expose the metal first.

3.  Place the magnet on the pipe.

4. Take a photo of the scratched pipe and submit your results by email with this form.

Types of Pipes

Lead Pipe:  A magnet will not stick to a lead pipe. Scratch the pipe with a coin.  If the scraped area is shiny silver and flakes off, the service line is lead.

Copper Pipe: A magnet will not stick to a copper pipe.  Scratch the pipe with a penny.  If the scratched area is copper in color, like the penny, your service line is copper.

Galvanized Steel Pipe:  If a magnet sticks to the surface, your service line is galvanized steel.  A scratch test is not needed, if you scratch it, it will remain a dull gray.
