Lead Service Lines in Casper, WY

What you need to know

Casper's water systems serve about 75,300 people across 45 different utilities. The good news: no confirmed lead service lines have been reported in the city's inventory data. However, this doesn't mean lead pipes don't exist—it means either they haven't been found yet, or records are incomplete.

Lead service lines are pipes that connect your home to the water main buried under the street. They're only a concern if water sits in them for hours (like overnight) before you use it. If you have a lead service line, simple steps like flushing your pipes can reduce exposure.

Which utilities serve Casper?

The largest provider is City of Casper (59,000 people), followed by smaller systems like Evansville, rest areas, and Vista West Water Company. Each utility maintains its own records and may have different information about their service lines.

How do you know if you have a lead service line?

Start by contacting your water utility directly. Most utilities now keep inventories of service line materials, though records from older installations can be spotty.

Quick ways to check:

  • Call your water utility and ask about your service line material
  • Ask if they have a map or inventory you can access
  • If your home was built before 1986, lead lines are more likely (though not guaranteed)
  • Your utility can also do a simple inspection if you're unsure

What should you do right now?

You don't need to panic, but it's worth getting clarity. If your utility can't confirm your service line material, or if you do have lead, there are proven ways to minimize risk.

Next steps for residents

  • Contact your water utility (City of Casper or your local provider) and ask about your service line material
  • Ask if they offer free testing for lead in your tap water—many utilities do
  • If you have concerns, the CDC website has straightforward guidance on reducing lead exposure
  • Keep records of any information your utility provides about your address and service line

Common questions

Is there lead in Casper's tap water?

No lead service lines have been reported in Casper's inventory data. However, the safest way to know if lead is present in your home's water is to ask your utility for a free test or get your water tested by a certified lab.

How do I find out what water system serves my address?

Call the City of Casper Water Department or your local utility directly with your address. They can tell you the material of your service line and whether they've tested your water.

When were lead service lines used in Wyoming?

Lead pipes were commonly installed in homes and buildings built before the 1980s, though some existed in earlier decades. Homes built after 1986 are unlikely to have lead service lines.

What do I do if my service line is made of lead?

Flushing your pipes (running cold water for 30 seconds to 2 minutes before drinking) significantly reduces lead exposure. Talk to your utility about long-term options like replacement—many areas now offer assistance programs.
