Metropolitan Council Environmental Services (MCES), operator of the metro-area wastewater collection and treatment system, is making improvements to aging and deteriorating regional sanitary sewer facilities that serve homes and businesses near MSP International Airport in the cities of Richfield and Minneapolis.
Most of the work required includes rehabilitating maintenance holes and inserting a liner into an existing sanitary sewer pipe to form a new pipe. This process is called Cured-in-Place Pipe (CIPP). One of the sites near the intersection of Diagonal Blvd. and Cedar Ave. requires open excavation to install the new pipe. The project is anticipated to be completed in three stages between March and December 2017 (see map below). Restoration work will continue through summer of 2018.
