Project Overview

Metropolitan Council Environmental Services (MCES), operator of the metro-area wastewater collection and treatment system, inspected the regional sanitary sewer pipes between Chaska and Shakopee. The pipes were originally constructed in the 1990s and have a variation of elevation changes and curves, lending to potential build-up of gases and deterioration.  The project also included sewer pipe cleaning and restoration of a service road in the area.

How the Inspection Was Done

The project used SmartBall technology to inspect approximately 15,000 feet of pipes. Crews inserted a golf ball-sized sphere into the sewer pipes that flowed downstream and analyzed the pipes with the use of an acoustic sensor to detect potential pipe deterioration. The ball was inserted near lift station (L71) near 2nd St. and Beech St. in Chaska and flowed downstream to its retrieval point by Marystown Rd. and Hwy. 169 in Shakopee.
