Lead Service Lines in Post Falls, ID

What you need to know

Post Falls has 22 water systems serving approximately 42,807 people. Currently, no known lead service lines have been reported across the city's water utilities. However, "unknown" doesn't mean "safe"—many water systems haven't completed full inventories of their service lines yet. Idaho utilities are still working through state and federal requirements to identify which pipes are lead, galvanized steel (which can corrode and leach lead), or other materials.

Why this matters

Lead service lines are pipes that carry water from the main water line in the street to your home. If your service line is lead, water can pick up lead as it travels through the pipe, especially if the water is acidic or sits in the pipes for hours. Even small amounts of lead exposure can affect children's development and learning. The good news: lead in water is preventable through simple steps like running your tap and using filters.

Your water systems

The five largest utilities serving Post Falls are:

  • Post Falls City of (20,285 people)
  • East Greenacres Irrigation District (11,165 people)
  • Ross Point Water District (8,965 people)
  • Pine Villa Park and Water Association (500 people)
  • Royal Highland Water System (275 people)

None have reported known lead service lines yet. That said, many utilities across Idaho are still collecting inventory data. Your utility may not have complete information on all service lines in your neighborhood.

What to do now

The most reliable way to know if your home has a lead service line is to contact your water utility directly. They can tell you what material your service line is made of. If you don't know which utility serves you, search your water bill or call Post Falls City Hall.

If you're concerned about lead in your drinking water while you investigate, the EPA recommends running your tap for 30 seconds before drinking or cooking, and using a pitcher filter certified to remove lead.

Next steps for residents

  • Find your water utility. Check your water bill or call Post Falls City Hall at (208) 773-7543.
  • Ask about your service line. Contact your utility and ask what material your service line is made of. They may have records or can arrange an inspection.
  • Check the CDC's guidance on lead and children's health if you have young children at home.
  • Use a filter if you want extra assurance while waiting for answers—look for NSF/ANSI 53 certification for lead removal.

Common questions

Does Post Falls have lead in the water?

No known lead service lines have been reported across Post Falls' water systems. However, many utilities haven't finished inventorying all service lines yet. Contact your water utility to find out if your specific home's service line is lead.

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

Call your water utility and ask. They can look up your address and tell you what material your service line is made of. You can also check your water bill to find your utility's name and number.

Is it safe to drink water from a lead service line?

Lead can leach into water through lead pipes, but the risk varies based on water chemistry, pipe age, and how long water sits in the pipe. Running your tap for 30 seconds and using a certified pitcher filter (NSF/ANSI 53) can reduce exposure.

What should I do if my service line is lead?

Contact your water utility about replacement options and costs—some offer financial assistance. In the meantime, use the tap-running and filtering methods above. If you have children under 6, talk to your pediatrician about lead testing.
