Water Main Replacement Projects
Milwaukee Water Works (MWW) is investing in the future of your public drinking water system.
Each year, as required by the Public Service Commission, MWW replaces approximately 14 miles of water mains. This represents a $25 million annual investment to ensure continuous access to safe, clean drinking water.
Why are water mains replaced?
MWW uses an index that ranks water mains by their condition and likelihood of failure. Some projects are also scheduled early to coordinate with street paving or major development projects.
How are these projects funded?
They are funded in part by the Wisconsin Safe Drinking Water Loan Program (administered by the DNR) and by revenue from ratepayers.
How long does a replacement take?
Most projects take about 6–12 weeks to complete during the construction season (April–December, weather permitting).
Will this affect my water service line?
If a main replacement project requires replacing your lead service line, you will be notified. You can search your address to see service line is made of lead and learn more about the Lead Service Line Replacement Program.
