Lead Service Line Records

Search our records to see if a property has a lead service line. If it does, it will be listed here.

Our records list properties in Milwaukee with Lead Services Lines (LSLs) whether the property includes the utility-owned section from the main to the curb stop, the privately-owned section from the curb stop to the meter, or both. There are 164,000 water service lines in Milwaukee; as of December 31, 2022, there are approximately 66,000 active resdiential service lines. 

We update our database as we replace LSLs and when our meter technicians identify a LSL while replacing a water meter. If your property is listed here but you replaced your section of lead service line with copper, please call Customer Service at (414) 286-2830 or email [email protected] and we will update our records.

A Sept 2017 EPA report quantified and compared contributions of lead from air, soil/dust, water and food to children's blood lead levels.

Children living in older homes with lead-based paint hazards by far have the most exposure to lead. For 1- to 6- year olds in the top 90-100 percentile, more than 70% of the lead in their blood was from soil and dust. The contribution from food was 20% and drinking water was 10%. For infants, soil and dust contribute to 50% of the lead in blood, while 40% was from water and 10% from food. The EPA is now evaluating approaches to setting a health-based benchmark for lead in drinking water.
