Current Projects: West Interceptor Rehab-Segoe Road to Shorewood Boulevard

Home / What We Do / Current Construction Projects / West Interceptor Rehab-Segoe Road to Shorewood Boulevard

Project overview

The District is completing this project to provide safe and reliable wastewater conveyance to residents and businesses while protecting public health and the environment. Rehabilitation of the West Interceptor will provide structural stability, improve flows, prevent infiltration of groundwater and extend the life of the interceptor. An interceptor is the largest component of a sewer network. It receives flow from smaller sewer lines and directs sewage to the wastewater treatment plant. 

The West Interceptor serves the City of Middleton, the City of Madison, the Village of Shorewood Hills, and the Town of Westport. The portion of the West Interceptor to be rehabilitated with this project is among the oldest interceptors in the District’s collection system, dating back to 1932. The existing pipe contains structural defects which warrant rehabilitation. The existing manholes are exhibiting signs of corrosion, general wear and need rehabilitation.

This project will rehabilitate a portion of the existing West Interceptor pipe and manholes. View a map of the project overview. To renew the pipe, this project will utilize a trenchless technology, cured-in-place-pipe (CIPP), to minimize disturbance. The project anticipates needing to bypass flow temporarily though the uses of pumps, hoses and ramps. Due to the location of the existing interceptor, there will be necessary temporary traffic impacts along University Avenue and Shorewood Boulevard for access of the trenchless technology. Manhole renewal will be performed with a general cleaning, prepping, coating and inspection – requiring access through each manhole lid. The District is coordinating with the City of Madison and Shorewood Hills for this work.

Public involvement

The public will be notified in advance of traffic closures. Businesses and residences adjacent to the work will be notified by the contractor in advance to minimize water use.  The contractor will make special arrangements to maintain water flow from high flow properties as needed.
