Project Overview
Phases 5 & 6 of the Lower Badger Mill Creek Interceptor will complete a regional sanitary sewer interceptor that was more than 20 years in the making. Representatives from the District, Town of Verona, City of Verona, and City of Madison met in 2001 to discuss planning for sewerage service in the Lower Badger Mill Creek drainage basin. This basin includes parts of the far west side of Madison, the town of Middleton, the town of Verona, and the City of Verona. It was determined that the best way to serve the basin was with 30,000 feet of sanitary sewer interceptor pipe.
The initial design of the entire 30,000 feet of interceptor pipe was started in 2004 and completed in 2006. The upper 12,000 feet of the regional interceptor was constructed by the City of Madison in 2015 and 2016. The lower 9,500 feet was constructed by the District in phases 1 through 4 from 2006 to 2018. Phases 5 and 6 will complete the final middle 8,500 feet of the interceptor pipe. When complete, the new interceptor pipe will convey an average sewage flow of approximately 3 million gallons per day and enable the decommissioning of a temporary City of Madison sanitary sewage pump station (also called a lift station) at Midtown Road. Phases 5 and 6 will use the initial 2006 design as a starting point and will incorporate minor deviations from the initial design as appropriate.
What are interceptors and pump stations?
An interceptor is a sewer pipe that receives wastewater from smaller local sewer pipes that serve neighborhoods or municipalities. Interceptors are the largest pipes in the sewage system and convey wastewater by gravity to pump stations or treatment facilities.
A pump station sits at a low point within a sewer service area basin (or drainage basin). Wastewater flows by gravity to the pump station and from there it is pumped through a pressurized pipe called a force main over hills and ridges to a higher elevation where it can again flow by gravity on its way toward the regional treatment plant.
General Route and Anticipated Schedule
The Phase 5 project will run from County Highway PD to Shady Oak Lane and includes approximately 3,200 feet of interceptor pipe. Construction of Phase 5 will take place in spring/summer 2023. Phase 6 will include 5,300 feet of interceptor pipe from Shady Oak Lane to Midtown Road. Construction of Phase 6 will take place in 2024.
