From the MMSD and City of Wauwatosa:

YOU’RE INVITED! OPEN HOUSE for MMSD’s Martha Washington/ Highlands Sewer Improvement Project

Thursday, April 30, 2026

6:30-8:00 PM

WASHINGTON ELEMENTARY SCHOOL

2166 N. 68TH STREET, WAUWATOSA

This summer, MMSD will begin construction on a major sewer improvement project that will:

• rehabilitate 12,000 feet of
  MMSD’s sewers,
• increase capacity, and
• reduce the risk of overflows.

The improvements will extend the life of the MMSD’s sewer by 50 years.

The rehabilitation work will take place in sewers along North Avenue between 69th and 67t and through the following neighborhoods:

• Washington Highlands
• Tosa East Towne
• Olde Hillcrest
• Inglewood
• Pabst Park

A sewer will be excavated and replaced on Garfield Avenue between 67th and 66th Street to increase sewer capacity.

At the open house, you will:

• Meet the project team.
• Learn about the process used to rehabilitate sewers.
• Find out about the project timeline.
• See the traffic plan that will be in place during construction.

The project will address the need for increased capacity and the reduction of sewer overflows. The improvements will extend the life of the current MIS by 50 years. Approximately 12,000 feet of MIS will be rehabilitated by lining segments to create a pipe within a pipe. This process is called cured-in-place-pipelining or CIPPL. This trenchless approach is cost-effective and reduces impacts on the businesses and residents during construction.

Work will progress segment by segment (manhole to manhole). There will be traffic impacts along the work areas. During construction, travel lanes will be reduced. Parking lanes and bike lanes will be closed in some areas. Traffic maps and travel impacts will be posted to this webpage before construction begins. They will be found in the project documents/resources section below.

The capacity improvement portion of the work will take place along Garfield Avenue between 67th St and 66th Street. The carrying capacity of the MIS sewer will be increased by increasing the size of the local sanitary sewer in this area, decreasing demand on the MIS. This sewer installation will involve digging the trench for the new pipe, connecting the sewer laterals, burying the new pipe, and restoring the roadway. Garfield Avenue will be closed to through traffic during the sewer construction and restoration work. Access to driveways will be provided.
