Lead service lines in Gillette, WY

What you need to know

Gillette's water systems serve 49,156 people across the city and surrounding areas. The good news: no lead service lines have been identified in available utility records. However, many water systems in the area—including the City of Gillette (which serves 32,222 residents)—have not yet completed a full inventory of their service lines.

This doesn't mean there are no lead lines. It means the data is incomplete. Lead service lines are pipes that connect your home to the water main. If your home was built before 1950 or you're unsure about your service line material, there's a real possibility it contains lead.

Why this matters

Lead in drinking water comes from corrosion of old pipes and plumbing fixtures, not the water source itself. Even small amounts of lead exposure can affect children's brain development. Older homes and those built between 1950 and 1980 are at higher risk, though lead lines exist in homes of all ages.

What Gillette utilities are doing

The five largest water systems serving Gillette are:

  • City of Gillette (32,222 people)
  • Sleepy Hollow Subdivision (2,400 people)
  • Antelope Valley I&S District (1,280 people)
  • Fox Park Subdivision (843 people)
  • Heritage Village Subdivision (750 people)

These utilities are required by federal law to develop lead service line inventories by October 2024. Most have not yet published complete records, but they are collecting data. Contact your utility directly to ask about your property's service line.

How to find your water provider

If you live within Gillette city limits, contact the City of Gillette's water department. If you're in a subdivision or rural area, identify your provider by checking your water bill or calling 911 and asking which system serves your address.

Next steps for residents

  • Call your water utility and ask if your service line contains lead. Provide your address.
  • Request a water test if you're concerned; most utilities offer free or low-cost testing.
  • Ask about line replacement programs — some utilities offer cost-sharing for removal.
  • Reduce exposure now: Use a certified lead filter or boil water for drinking and cooking while you investigate.

Common questions

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

Contact your water utility with your address. The City of Gillette and other local providers are required to maintain lead service line inventories. You can also hire a plumber to inspect the pipe where it enters your home, or look at your water bill to see if your utility has published an inventory online.

Is Gillette water safe to drink?

Gillette's water source itself is safe. The risk comes from lead pipes and plumbing in older homes. Get a free or low-cost water test from your utility if you're concerned, especially if your home was built before 1980.

What should I do if I think I have lead pipes?

Call your water utility to confirm your service line material. While you wait for results, use a certified lead filter, boil water for drinking and cooking, and flush your cold-water tap for 30 seconds before use. A pediatrician or the CDC can advise on health concerns.

Does Gillette have a program to replace lead service lines?

Contact the City of Gillette or your specific water provider directly to ask about replacement programs and any financial assistance available. Some utilities offer matching funds or low-interest loans.
