Lead service lines in Twin Falls, ID

What we know about lead pipes in Twin Falls

Twin Falls serves about 62,000 people across 38 water systems. Based on available inventory data, no confirmed lead service lines have been reported in the area's public water systems.

This is good news—but it comes with an important caveat. Many water systems, including some in Twin Falls, have not yet completed a full inventory of their service lines. "Unknown" doesn't mean "safe"; it means the data isn't finished. Idaho water utilities are required to complete lead service line inventories by October 2024, so more information may become available soon.

The City of Twin Falls serves the majority of the area's population (56,121 people). This is the system most Twin Falls residents rely on. The utility has not yet reported a count of known lead or galvanized service lines in the available data, which suggests their inventory work may still be underway.

You can contact the City of Twin Falls directly to ask whether they've completed their service line inventory and what they've found so far.

What you can do about your own home

Your home's service line—the pipe connecting your house to the public main—is typically owned by you if it's on your property. Even if your water system has no known lead, some older homes have lead or galvanized steel service lines installed decades ago.

If your home was built before 1986, the risk is higher. The best way to know your home's status is to have your water tested for lead and to ask your utility whether they have records of your service line material.

Next steps for residents

  • Contact the City of Twin Falls or your local utility to ask if they've completed a lead service line inventory and share the results with you.
  • Request a water test from your utility or a certified lab if you're concerned about lead in your home's drinking water.
  • Check your home's age and service line — ask neighbors, look at property records, or contact a plumber to inspect the line where it enters your house.
  • Visit the EPA's lead page for more information on testing and treatment options.

Common questions

Does Twin Falls have lead in the water?

No confirmed lead service lines have been reported by Twin Falls water systems based on available inventory data. However, some utilities are still completing their inventories, so check with your local water provider for the most current information.

How do I know if my house has a lead pipe?

Lead pipes are soft and dull gray; you can scratch them with a coin. Check where the service line enters your home, or ask your water utility if they have records of your line's material. Homes built before 1986 are at higher risk.

Should I get my water tested for lead in Twin Falls?

If your home has a lead or galvanized service line, or if it was built before 1986, testing is a good idea. Contact the City of Twin Falls water department or a certified lab to arrange a test.

What should I do if I find lead in my water?

Run water for 30 seconds before drinking or cooking, use cold water for consumption (hot water leaches lead faster), and contact your utility about treatment options. For health concerns, speak with your pediatrician or call the CDC.
