Lead service lines in Stillwater, OK

What you should know

Stillwater serves about 73,000 people across 11 water systems. The largest is Stillwater Utilities Authority, which serves roughly 53,000 residents, followed by OSU Water Plant (13,000 residents) and several smaller rural water systems.

Currently, no lead service lines have been identified in the water systems serving Stillwater. This is good news—but "unknown" doesn't mean "zero." Older pipes in your neighborhood may not yet have been surveyed, and lead can still enter your water if your home's internal plumbing contains lead solder or brass fittings.

Why this matters

Lead service lines are the pipes that connect the water main under the street to your home. If your line is made of lead, water can pick up lead as it travels to your tap—especially in homes built before 1980, or in areas with naturally soft or acidic water. Even small amounts of lead exposure can affect children's development.

The good news is that lead in water is preventable. Flushing your tap, using cold water for drinking and cooking, and installing a filter can all reduce exposure while you work toward long-term solutions.

Next steps for residents

  • Contact your water utility to ask about their lead service line inventory and whether your property has been surveyed. You can find your system's contact information below.
  • Have your water tested if your home was built before 1980 or if you're concerned about lead. Your utility can direct you to certified labs.
  • Use cold water for drinking and cooking. Hot water dissolves lead more readily than cold.
  • Flush your tap for 30 seconds to several minutes each morning before drinking or cooking, especially if water has sat in pipes overnight.

Common questions

Does Stillwater have lead in the water?

No lead service lines have been confirmed in Stillwater's water systems so far. However, surveys are ongoing, and older homes may still have lead solder or brass fittings in interior plumbing. Testing your water is the most reliable way to know your home's status.

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

Contact your water utility—they maintain records of service lines. You can also dig up the pipe where it enters your home and look for a dull gray metal that's soft enough to scratch with a coin. A certified plumber can also inspect for you.

Is it safe to drink tap water in Stillwater?

Tap water in Stillwater is regularly tested and meets federal safety standards. If you have concerns about lead specifically, flush your tap before drinking, use cold water, and consider having your water tested—especially if your home was built before 1980.

How much does it cost to replace a lead service line?

Replacement typically costs $3,000–$25,000 depending on the length and depth of the line. Some utilities offer cost-share or assistance programs; contact Stillwater Utilities Authority or your local system to ask about rebates or financing options.
