Lead service lines in Billings, MT

Billings and the surrounding area are served by 113 water systems, with the City of Billings providing water to approximately 114,000 residents. If you're concerned about lead in your home's water pipes, here's what you need to know.

What we know about lead pipes in Billings

As of the most recent data available, there are no confirmed lead service lines documented in Billings' water system inventory. However, "no data" doesn't mean "no pipes"—it means your utility hasn't yet completed a full survey of all connections. The EPA requires utilities to identify and replace lead service lines by 2027, which means many systems are still in the process of mapping their infrastructure.

Who provides your water?

The largest utilities serving the Billings area are:

  • City of Billings (114,000 people)
  • Billings Heights County Water District (12,000 people)
  • Lockwood Water and Sewer District (5,900 people)
  • Rocky Mountain College and Montana State University Billings also operate their own water systems

How to find out if you have a lead service line

Your water utility maintains records about the pipes connecting your home to the main water line. This is the only definitive source.

Contact your water provider directly and ask:

  • "Do I have a lead service line?"
  • "What records do you have about my service line material?"
  • "When will your lead inventory be complete?"

If your utility hasn't finished surveying all connections, ask when they expect to complete that work.

What if your utility doesn't know?

If your home was built before 1986, or if records are unclear, there's a higher statistical chance your service line contains lead—but it's not guaranteed. You can:

  • Have a licensed plumber inspect the visible portion of your service line
  • Request a water test from your utility (often free or low-cost)
  • Install a water filter certified for lead reduction if you're concerned

Next steps for residents

  • Contact your water utility using the utility name and contact info above—ask specifically about lead service lines at your address
  • Request a water test if you're concerned; most utilities offer this at no charge
  • Learn more from the EPA's lead and copper rule page for details on testing and treatment options
  • Talk to a pediatrician if you have young children; they can discuss whether additional precautions make sense for your household

Common questions

Does Billings have lead pipes in the water system?

There are no confirmed lead service lines documented in current Billings water system data. However, utilities are still completing full inventories—the EPA deadline for identification is 2027. Contact your water provider to ask about your specific address.

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

Call your water utility and ask directly about the service line material at your address. If records are unclear or your home was built before 1986, a plumber can inspect the visible portion of your line, or your utility can test your water.

Is Billings water safe to drink?

Your water utility regularly tests for contaminants including lead and publishes results in an annual Consumer Confidence Report. You can request this report from your utility or find it online—it's the best source for current safety data specific to your system.

What should I do if I'm worried about lead in my water?

Request a free water test from your utility, have your service line inspected by a plumber, or install a certified lead-reducing filter. For health concerns, speak with your pediatrician or contact the CDC.
