City of Grand Rapids Eastside Trunk Sewer Relocation

The City of Grand Rapids engaged our team and another local firm as consulting engineers to complete a design for the City of Grand Rapids Engineering Department in the Spring of 2020 during the start of the COVID-19 pandemic. Though the timing complicated meetings needed to complete this complex project, the parties adapted to the online environment and kept design moving forward.

The project objective was to move a mainline sewer from its current location, bisecting properties fronting the Grand River from Fulton Street to Wealthy Street, into the Market Avenue right-of-way. This undertaking allows for future redevelopment of the burdened parcels and puts the sewer in the city-owned right-of-way. The length of the abandoned sewer totals 2,200 feet and is an 11.25-foot-tall by 12-foot-wide cast-in-place structure built in the 1890s. The sewer constructed in Market Avenue to relocate this main is a 96-inch diameter precast concrete sewer totaling 2,450 feet.
