STILLWATER UTILITIES AUTHORITY Lead Service Line Inventory
Stillwater Utilities Authority serves about 53,000 people in Oklahoma. If you're a customer and wondering whether lead could be in your water pipes, this page explains what the utility has reported about lead service lines—and what you can do next.
What is a lead service line?
A lead service line is the pipe that carries water from the public main line under the street into your home. These pipes were commonly installed before the 1980s because lead is easy to work with and was thought to be safe. We now know lead can leach into drinking water, especially in homes with older plumbing.
What does Stillwater Utilities Authority report?
As of now, Stillwater Utilities Authority has not yet inventoried its service lines for lead. This means the utility has not publicly reported how many lead, galvanized, or non-lead pipes serve its customers. This is not unusual—many utilities across the country are still in the early stages of mapping their systems.
Federal law requires all water systems to complete a full lead service line inventory by October 2024. If Stillwater hasn't published its inventory yet, it should be available soon. Check the utility's website or contact them directly for the most up-to-date information.
Why does this matter?
Lead service lines are the most common source of lead in drinking water at home. Even if your utility's water is treated to prevent corrosion, old lead pipes can still pose a risk—especially to young children and pregnant people, whose bodies absorb lead more easily.
How to find out about your home
Your service line may be lead, galvanized (steel coated with zinc, which can also corrode and release metals), or non-lead materials like copper or plastic. The only way to know for certain is to:
- Check your home's documentation or blueprints if available
- Ask your utility whether records show your service line material
- Have a licensed plumber inspect and test the pipe if you can access it
Once you know your service line type, you can decide on next steps—from flushing practices to replacement.

Frequently asked
Does Stillwater have lead in its water?
Stillwater Utilities Authority has not yet published a complete lead service line inventory. Lead in drinking water usually comes from old pipes in individual homes, not from the utility's main system. Contact the utility to ask about your specific service line.
How do I know if my house has a lead service line?
Ask your water utility if it has records of your service line material. You can also have a licensed plumber inspect the pipe where it enters your home. A magnet test can help identify galvanized steel, but the only certain way is visual inspection or lab testing.
Is lead in water dangerous for kids?
Yes. Young children absorb lead more easily than adults, and even small amounts can affect development. If you think you may have a lead service line, contact your pediatrician or the CDC for guidance on testing and next steps.
What should I do if I have a lead service line?
Flush your pipes before drinking, use cold water for cooking and baby formula, and consider replacement. Some utilities offer replacement programs or financial help. Contact Stillwater Utilities Authority to ask about your options.
