Current Projects: Northeast Interceptor Joint Grouting

Home / What We Do / Current Construction Projects / Northeast Interceptor Joint Grouting

Project overview

Madison Metropolitan Sewerage District is joint grouting the conveyance sewer along the Marsh View Bike Path between Highway 30 and West Corporate Drive. This project rehabilitates existing sewer infrastructure between manholes 10-106 and 10-101 to continue to serve the needs of the community.

An interceptor is the largest component of a sewer network. It receives flow from small sewer lines and directs sewage to the wastewater treatment plant. The portion of the interceptor that will be rehabilitated in this project was built in 1964 and serves the City of Madison and the Village of Waunakee.

Routine interceptor inspection revealed numerous joints are suffering from inflow/infiltration, which means groundwater is getting into the sewer system. This project will grout the joints to prevent further inflow/infiltration from occurring. This will help preserve the integrity of this conveyance sewer for use today and in the future.

Marsh View Bike Path is anticipated to remain open during this work. Path users are encouraged to use caution in the area. There will be select planned tree removals necessary to complete the work. Additionally, some off-hours work will be needed. Work is anticipated to start mid-November 2021 and be complete mid-May 2022.

Public involvement

Due to the nature of the project, no public information meetings are required for this project.

Businesses within 100 feet of the project area were provided notification of tree removals. The District has also communicated bike path and project impacts to the City of Madison, the Madison biking community, and the Friends of Starkweather Park group.
