What We Know About Lead Service Lines Here

Lewiston has 22 water systems serving about 39,182 people. Based on publicly available inventory data, no known lead service lines have been reported in the city's systems to date.

  • Clearwater Paper Corporation (1,550 people)
  • Federal Cartridge Company (765 people)

Why This Matters

A lead service line is the pipe that connects your home to the city's water main. If yours is made of lead, water can pick up lead as it travels into your house. Lead exposure is a serious public health concern, especially for young children and pregnant people. Even low levels can affect child development.

The EPA requires water systems to test for lead at the tap and maintain inventories of service line materials. However, many older systems don't yet have complete records of what their pipes are made of.

How to Find Out About Your Home

Start by contacting your local water utility directly. Ask them:

  • Do you have a lead service line inventory?
  • What material is the service line to my address?
  • If unknown, what's your plan to find out?

The three main utilities serving Lewiston are listed above. Your water bill should tell you which system serves your property. If you're unsure, call your city's water department.

If your utility doesn't have definitive information, you can hire a licensed plumber to check the service line at your property line. You can also have your water tested for lead; some utilities offer free testing.

Next Steps for Residents

  • Contact your water utility (use the system names above) and ask about your service line material.
  • Check your water bill for the utility name and contact information.
  • Request a lead test if your utility offers one, or hire a certified lab to test your tap water.
  • Visit the EPA's lead page for guidance on reducing exposure while you investigate.

Common questions

Does Lewiston have lead pipes in the water system?

No known lead service lines have been reported in Lewiston's 22 water systems to date. However, many utilities are still completing their inventories, so records may be incomplete. Contact your local utility to ask about the service line at your home specifically.

How do I know if my house has a lead service line?

Call your water utility and ask them directly—they should have or be building an inventory of service line materials. If they don't have records for your address, a licensed plumber can inspect the service line at your property line.

Is the water in Lewiston safe to drink?

Water systems are required to test for lead at the tap and report results. Your utility should have a Consumer Confidence Report available; ask them for it. If you're concerned, you can have your tap water tested for lead by a certified lab.

What should I do if my home has a lead service line?

Contact your utility about their replacement or mitigation programs—some offer financial assistance. In the meantime, run cold water for 30 seconds before drinking, use cold water for cooking and baby formula, and consider a certified lead-reducing filter while you plan replacement.
