Milwaukee Waterworks Lead Service Line Inventory

What You Need to Know

Milwaukee Waterworks serves approximately 626,000 people across the city and surrounding areas. Like many older water systems in the US, Milwaukee may have lead service lines—the pipes that connect the public water main to individual homes. Lead service lines are a known source of lead in drinking water, especially in homes built before the 1980s.

The current status: Milwaukee Waterworks has not yet completed a full inventory of lead service lines in its system. This means the utility does not yet have a documented count of how many service lines contain lead, are galvanized steel, or are confirmed lead-free.

Why This Matters

Lead exposure, even at low levels, can affect children's brain development and learning. There is no safe level of lead in drinking water for children. If your home was built before 1990—particularly before 1950—there is a higher chance your service line contains lead.

A service line is the pipe running from the street water main directly to your home. Even if your home's interior plumbing is new, the service line may still be lead.

What Milwaukee Waterworks Is Required to Do

Under federal law, water utilities must create and maintain an inventory of all lead and galvanized service lines. Milwaukee Waterworks is working toward this requirement, though the inventory remains incomplete.

You can check the utility's progress and find more details by contacting them directly or visiting their water quality information pages.

What You Can Do Now

Test your water. If you suspect lead in your service line, a simple water test can measure lead levels in your tap water. The EPA provides free or low-cost testing resources.

Know your home's age. Homes built before 1950 are at highest risk; those built 1950–1990 have moderate risk.

Reduce exposure while you wait. Run cold water for 30 seconds before drinking or cooking if the water has sat in pipes overnight. Use cold water only for cooking and drinking (hot water leaches more lead).

Next Steps for Residents

• Contact Milwaukee Waterworks to ask about the lead service line status of your specific address and when the full inventory will be completed.
• Request a free water test through your utility or a certified lab to know your current lead levels.
• Check your home's age (deed, property records, or realtor estimate) to gauge risk.
• Visit the EPA's lead and copper rule page for more information on service lines and health protection steps.

You can also have a plumber inspect the visible portion of your service line in the basement or yard, though the entire line may be buried. A water test will tell you if lead is actually in your tap water." }, { "q": "Is Milwaukee water safe to drink?", "a": "Milwaukee Waterworks tests drinking water and reports results publicly. Lead in drinking water comes primarily from service lines and indoor plumbing, not the treated water supply itself. If you have an older home with a likely lead service line, a water test and precautions like flushing can help reduce exposure." }, { "q": "How much does it cost to replace a lead service line?", "a": "Replacement costs vary widely depending on line length, depth, and soil conditions—typically $3,000 to $25,000 per line. Many states and utilities now offer rebates or cost-sharing programs. Contact Milwaukee Waterworks about current assistance options." }, { "q": "What should I do if my water tests high for lead?", "a": "Use bottled water for drinking and cooking until you can address the source. Contact your utility to discuss next steps and ask about replacement funding. For health concerns, especially with
