Project Overview

Metropolitan Council Environmental Services (MCES) cleaned a regional sanitary sewer interceptor located on the west side of Saint Paul from March 2019 through August 2019.  The regional sanitary sewer interceptor consists of a tunnel partially lined with clay tile.  The upper portion of the tunnels are exposed sandstone. Inspections of the sandstone tunnel indicated that debris removal is needed to maintain sewer operations and improved access was needed for debris removal and future maintenance activities.

The following work was completed:

  • Removal of debris from the sandstone tunnel.
  • Installation of new maintenance hole and shaft on George Street between Livingston Avenue and Robert Street.
  • Installation of a city-owned maintenance hole at the intersection of State Street and Stevens Street. This site was also used for access to the sandstone tunnel during cleaning.
