Lead Service Lines in West Allis, WI

What you need to know

West Allis serves about 63,400 people through five water systems. The largest is West Allis Waterworks, which supplies water to roughly 63,240 residents.

Lead service lines—the pipes that connect your home to the water main—are a real concern in many older US cities. They can leach lead into drinking water, especially in homes built before the 1980s. Wisconsin requires water utilities to maintain inventories of these lines and share that information with the public.

Lead service line data for West Allis

The data we have does not yet show a specific count of known lead service lines in West Allis Waterworks or the smaller systems serving the area. This does not mean there are no lead lines—it means the utility's full inventory is not yet public in this directory, or they are still completing their survey.

What this means for you: You should contact your water utility directly to ask:

• Does your property have a lead service line?
• What year was your home built?
• What testing results are available for your water?

West Allis Waterworks maintains this inventory and is required to provide it to residents upon request.

Steps to protect your household

Even if you don't know your service line material, you can reduce lead exposure:

• Run cold water first. If your tap has not been used for several hours, flush it for 30 seconds to 2 minutes before drinking or cooking.
• Use cold water for drinking and cooking. Hot water leaches more lead from pipes.
• Get your water tested. Contact your utility to request a free or low-cost test, or use a certified lab.
• Consider a filter. If you have a lead service line, point-of-use filters certified for lead removal can help (look for NSF 53 certification).

If you have young children or are pregnant, talk to your pediatrician or doctor about your household water—they can assess your individual risk.

Next steps for residents

• Call West Allis Waterworks (or your smaller system if applicable) and ask about your service line material and any lead test results on file.
• Check your property deed or home inspection report for clues about when your home was built; homes pre-1980 are higher risk.
• Request a water test through your utility or a certified private lab.
• Visit the CDC's lead and water page for science-backed guidance on reducing exposure.
