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 Northeast Interceptor will provide structural stability, 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 Northeast Interceptor serves the Village of Waunakee, Village of Deforest, Village of Windsor, Town of Burke and City of Madison. This project will rehabilitate a portion of the existing Northeast Interceptor pipe and manholes. The portion of the Northeast Interceptor to be rehabilitated was constructed in 1969. The existing pipe contains surface and joint defects which warrant rehabilitation. The existing manholes have high levels of microbial induced corrosion and need rehabilitation.
For rehabilitation, this project will utilize cured-in-place-pipe (CIPP) to minimize disturbance where possible. Due to the large size of the existing interceptor, the manhole top decks will need to be removed in certain locations to facilitate the CIPP install. Around the clock work, including night work, will be necessary to cure the large diameter CIPP. The project anticipates needing to bypass flow temporarily though the uses of pumps, piping and ramps. Manhole renewal will be performed with a general cleaning, prepping, coating and inspection – requiring access through each manhole lid at the surface.
This project will be located along seven portions of the existing Northeast Interceptor:
- North of Rieder Road
- Southeast end of Dane County Regional Airport
- East of Bowman Street
- East of Wright Street
- Along Kinsman Boulevard to U.S. Highway 51
- S. Highway 51 from Kinsman Boulevard to Lien Road
- Lien Road from U.S. Highway 51 to Thierer Road
Due to the location of the existing interceptor and the scope of work, there will be necessary temporary traffic impacts along Kinsman Boulevard, N. Stoughton Road (U.S. Highway 51) and Lien Road. Off-street work, including work in the Dane County Regional Airport, is required as well. The District will be coordinating with the City of Madison, WisDOT, Dane County Regional Airport and the Town of Burke for this project.
Construction impacts
To be determined.
Public involvement
- Adjacent property owners will be contacted directly to schedule a 1:1 meeting in the future with the design team to provide input. These meetings will help the design team minimize traffic and/or sewer interruptions to the adjacent property.
- A public information meeting (date TBD) will be held to present the anticipated traffic impacts, construction sequence and schedule (subject to change). This meeting will provide information and resources for the public during construction.
