What your result means

If your service line is listed as “Lead”

We recommend taking steps to reduce lead exposure in your water.

Some properties are prioritized for replacement in 2026 under the Milwaukee Prioritization Plan (MPP). If your property is prioritized, Milwaukee Water Works will contact you with next steps for replacement.

If your service line is listed as “Unknown”

This means the material has not yet been confirmed in our records. You may have recieved a postcard with instructions on how to help update your information. You can submit photos through the online form to help identify your service line. If you need assistance or cannot submit photos, call (414) 286-8000 to schedule a visual inspection.
