Marsh View Bike Path to remain open, but users encouraged to use caution

MADISON — Madison Metropolitan Sewerage District has started a project to grout the joints in a portion of the Northeast Interceptor conveyance sewer along Marsh View Bike Path between Highway 30 and West Corporate Drive on Madison’s eastside.

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. It serves the City of Madison and the Village of Waunakee.

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

Marsh View Bike Path is anticipated to remain open during this work, but path users are encouraged to use caution in the area. Select, planned tree removals are necessary to complete the work. Additionally, some off-hours work will be needed. Work is anticipated to be complete by mid-May 2022.
