Deep Sewer Tunnel Cleaning Project
Metropolitan Council Environmental Services (MCES) will be cleaning six large diameter sanitary sewer interceptors in Minneapolis and St. Paul between in June 2017 and December 2018. (Full map)
Between May and June, MCES will be cleaning the interceptor pipes beneath Washington Avenue between 11th Avenue and 35W. There will be periodic lane closures near the work zone. Work hours on this site will occur during off-peak traffic times. Overnight cleaning work may occur.
Cleaning activities will include inspecting the pipes with CCTV and sonar equipment to confirm quantities and locations where debris will be removed; cleaning the pipes using high velocity water jetting equipment and removing debris with pumps; drying the debris; and hauling it to a licensed landfill. Jetting and debris removal will be conducted through existing access structures with minimal surface disruption and pavement restoration. Work will be conducted in existing rights of way under traffic, or overnights to minimize traffic disruption.
