Brown Deer Road Sanitary Sewer Replacement

Project Update

To reduce the risk of basement backups in homes and businesses, a Milwaukee Metropolitan Sewerage District contractor will be constructing a new sewer and closing Brown Deer Road at Regent Road and at Rexleigh Drive, starting the week of January 30th.  Access to the Bayside Garden Center and the residences along this section of road will be from the east side of Brown Deer Road.  Please view the map of the closure area. 

The marked detour route for those traveling eastbound is Port Washington Road to Green Tree Road to Lake Drive and the reverse for those traveling west bound.  Please view the detour map.

The project includes construction of a 27-inch sewer that will be installed using underground tunneling methods.  Large shafts, which look like big holes, are used to lower tunneling equipment underground (see picture). The project will be under construction through July 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.
