Lead Service Lines in Milwaukee, WI

Milwaukee's water system serves about 684,400 people through 71 separate water systems. The largest is Milwaukee Waterworks, which supplies roughly 626,000 residents across the city and some suburbs.

What we know about lead service lines here

Lead service lines—pipes that connect the water main to homes—are a concern in older cities. Milwaukee's infrastructure includes many older neighborhoods where these pipes are more common. However, current public inventory data does not yet show confirmed counts of lead service lines in Milwaukee's systems. This doesn't mean they aren't there; it means the utilities are still assessing their distribution networks or haven't published detailed counts.

Lead can leach into drinking water when water sits in these pipes, especially if the water is corrosive or hasn't been treated to prevent leaching. The risk is highest in homes built before 1986, when lead service lines were still legal.

What Milwaukee utilities should be doing

All water systems are required by the EPA to inventory their service lines and report findings. Milwaukee Waterworks and the smaller systems serving the area must:

• Identify which customers have lead service lines
• Notify affected residents
• Develop plans to replace lead lines (ideally starting with the most vulnerable populations—young children and pregnant people)
• Treat water to reduce corrosion and lead leaching

What you can do now

If you live in Milwaukee and don't know what material your service line is made of, contact your water utility directly. Milwaukee Waterworks maintains records of service line materials, and they can tell you what's serving your home.

If your service line is lead and you're concerned about water quality, you can:

• Use a water filter certified for lead removal (NSF/ANSI 53 rated)
• Have your water tested by a certified lab
• Flush your pipes before drinking if water has sat still overnight

For health concerns—especially if you have young children—talk to your pediatrician or contact the CDC's lead information line.

Next steps for residents

• Contact your utility: Call Milwaukee Waterworks at their customer service line or visit their website to ask about your service line material.
• Request testing: Ask if the utility offers free or low-cost water testing for lead.
• Check your home: If you live in a pre-1986 home and don't know your service line material, prioritize finding out.
• Learn about replacement: Ask your utility about lead line replacement programs and potential financial assistance.
