EPA Mandated Service Line Inventory

City of Brewer Water Department

Water Service Lines

You may have had, or will have, a Brewer Water Department technician knock on your door to inspect the service line in your basement or leave a red or orange door hanger at your home just recently.


We are in the process of updating our Service Line Inventory and have launched a community-wide project to identify what every service line (pipe that brings water to your home) in our system is made of.


Although the State of Maine falls in the low end range of lead service lines in the USA, we are required by federal law to maintain a service line inventory that identifies any potential lead service lines in our system.

The EPA has determined that lead service line inventories under the Lead and Copper Rule Revisions are necessary to achieve 100% removal of lead service lines. Lead and Copper Rule Revision Fact Sheet

We are asking that you provide us with the following information:

  • Date- When we received this information
  • Service Location- your physical address
  • The Year your House was Built- this helps us rule out lead service lines that the Safe Drinking Water Act (SDWA) prohibits the “use of any pipe, any pipe or plumbing fitting or fixture, any solder, or any flux, after June 1986, in the installation or repair of (i) any public water system; or (ii) any plumbing in a residential or non-residential facility providing water for human consumption, that is not lead free.” EPA Regulation of Use of Lead Free Pipes
  • Material- There are Four Options Lead, Copper, Plastic, & Galvanized Steel. You can find instructions on identifying the service line material Here.
  • Size of pipe- “Generally speaking, the main pipeline from the street to your home is either ¾ or 1 inch in diameter. Supply pipes are ¾ inch in diameter and individual components are ½ inch in diameter.”- American Home Water and Air
