Project Description

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.

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.
