Lead service lines in Waukesha, WI

What we know about lead pipes in Waukesha

Waukesha serves about 83,600 residents across 85 water systems. The largest is Waukesha Water Utility, which supplies roughly 70,700 people.

Currently, no lead service lines have been identified in Waukesha's public records. However, this doesn't mean lead pipes aren't present—it means either they haven't been fully inventoried yet, or none were found during testing.

Lead service lines are pipes that connect your home to the water main buried under the street. They were common in homes built before the 1980s, though they're found in all eras. If your home was built before 2000, there's a higher chance your connection contains lead.

How to find out if you have a lead service line

Start by contacting Waukesha Water Utility (the main system serving most residents). Ask them:

• Does your utility have a lead service line inventory for your address?
• If they do, is your line on it?
• If they don't have complete records, can they test the line at the meter and curb?

You can also hire a licensed plumber to visually inspect the line where it enters your home (in the basement or foundation), though a visual check alone isn't 100% certain.

If you're concerned about lead in your tap water

Testing your tap water is separate from identifying pipes. Even homes with lead lines don't always have elevated lead in water—it depends on water chemistry, pipe age, and how long water sits in the pipes.

The EPA recommends free or low-cost testing through your local health department. Results tell you whether action is needed.

If a child under 6 lives in your home or you're pregnant, talk to your pediatrician or doctor about testing and next steps.

What happens if lead service lines are confirmed

Wisconsin requires utilities to replace known lead service lines over time. The pace and funding depend on state and federal grants. Meanwhile, simple steps—like flushing cold water from your tap for 30 seconds before drinking, using cold water for cooking, and cleaning aerators—can reduce risk.
