Milwaukee Lead Service Lines: What to Ask Before Anyone Digs

Updated 2026-10 · Milwaukee, WI

The short version

Milwaukee Water Works plans to replace about 65,000 lead service lines by 2037 and is aiming for roughly 3,800 in 2026, through what it calls the Milwaukee Prioritization Program. If your home has one to four units and no commercial use, and the replacement is required, the city has charged owners nothing since January 2024. That rests on federal funding, and the city has said a cost share would return if that funding ends.

When replacement is required

City ordinance requires full replacement of a lead service line, both the public and the private section, in several situations. The ones a homeowner is most likely to meet:

• A leak or failure on either the city side or your side of the line.
• The city replacing its own section during a planned water main or street project.
• Your property being in a neighbourhood the city has prioritised for replacement.
• Licensed child-care facilities, which the city treats as a priority.

The ordinance generally does not allow a private lead line to be patched after a leak. That is why a leak on a lead service is a call to Milwaukee Water Works first, before a private plumber is booked for a repair.

If your neighbourhood is chosen

The city sends notice and asks the owner to sign a consent form so its contractor can enter the property. Owners can meet the contractor before work starts. The replacement itself typically takes four to six hours, with water off for an hour or two at the end. Because the work is required by ordinance, owners who do not sign may be referred to the Department of Neighborhood Services and can face inspection fees. The city reported in 2026 that about 70% of eligible owners in the programme had taken part.

If you want it done sooner

The Owner Request Program is for owners of one to four unit residential properties who want replacement before the city reaches them. From 2026 the city selects 200 properties a year. Owners pay for the private side, estimated by the city at $3,454 based on a five-year average, either within 45 days of the invoice or as a special assessment on the property tax bill over 15 years. Local reporting in 2026 put the backlog into 2029, so apply early if you want this route.

Questions worth asking

Ask Milwaukee Water Works

Is my address on the lead service line map, and is it in a prioritised area this year or next? If my side leaks, what happens and what does it cost me? Does the work include restoring the lawn and the basement wall where the new line enters?

Ask a plumber

Is the pipe after my meter lead or galvanised as well? Galvanised pipe that was connected to a lead service can hold lead in its scale. Will the new service need changes at the meter or the main shutoff? Is my main valve worth replacing at the same time? Those are the parts of the job the city programme does not touch inside your house.

Ask yourself

Who lives here? The Milwaukee Health Department recommends an NSF/ANSI Standard 53 certified lead filter, especially for pregnant people and children under six, and running the cold tap for about three minutes after water has been sitting.

Outside the city line

The programme above covers properties on Milwaukee’s system inside the city. Wauwatosa and West Allis run their own utilities with their own rules; West Allis has its own lead lateral ordinance. Check with your own utility.
