Lead Service Lines in Rock Springs, WY

What you need to know

Lead service lines are pipes that connect your home to the water main under the street. They were commonly installed before the 1970s, when lead was widely used in plumbing. Water traveling through a lead pipe can pick up lead, which poses health risks—especially to young children and pregnant people.

Wyoming doesn't have a statewide requirement to replace lead service lines, and most water systems here haven't identified widespread lead problems. However, if your home was built before the 1980s, there's a possibility your service line contains lead or galvanized steel (which can also leach metals over time).

How to find out if your home is affected

Your water utility can tell you what material your service line is made of. Contact the City of Rock Springs or your local water provider (listed below) and ask about your service line. They may have records, or they can arrange for someone to check. In most cases, the utility owns the line from the main to your property line, and you own the rest.

If you can't determine the material, the simplest approach is to have your water tested. Many health departments and private labs can test for lead at a reasonable cost.

What to do if you find lead

If your service line is confirmed to be lead, reduce exposure by running cold water for 30 seconds before drinking or cooking, and use cold water for baby formula. Talk to your pediatrician or contact the CDC for health guidance. Your utility can discuss replacement options; some water systems offer assistance programs.

Next steps for residents

  • Contact your water utility to ask about your service line material (start with the City of Rock Springs at the number on your water bill)
  • Request a water test if you're unsure about your pipes
  • Call your pediatrician if you have health concerns about lead exposure
  • Check the EPA's Lead and Copper Rule for your rights and your utility's responsibilities
