Brown Deer Road Sanitary Sewer Replacement

Project Update

To reduce the risk of basement backups in homes and businesses, MMSD's contractor is constructing a new sewer at Brown Deer Road between Regent Road and Rexleigh Drive. The project is progressing. The main sewer line has been installed.  The contractor is now working on connecting the new sewer to the existing sewers.  The laterals to the homes and businesses will also be connected to the new sewer.  Brown Deer Road will remain closed for this phase of the work.  Construction closures will continue through the project completion in August 2023. 

Project Overview

In 2019, MMSD completed a sanitary sewer evaluation and found that improvements to the existing sewer in East Brown Deer Road would reduce sewer backups.  The existing 15-inch sewer is being upsized to a 27-inch pipe to provide more storage and flow into the MMSD sewer system. Construction is anticipated to begin in winter 2023 and be completed by the end of summer 2023.

IMPORTANT! Water in the Basement can be dangerous

  1. Do not go into a basement with standing water. Electricity + Water = Danger.
  2. Call your municipal public works department to report the problem. If your municipality is unable to help you, call MMSD at (414) 272-5100 or report a wet basement.
  3. Call your homeowners/renters insurance agent.
  4. Wait for the water to drain out of the basement before entering. Or, call a qualified electrician to disconnect the power before you enter a flooded basement.
