Grand Green design
A new stormwater management system in Grand Rapids, Mich., is ready to hold as much as 750,000 gallons of water. Completed in September 2015, the $1.5 million underground storage unit was designed by engineering and construction company Black & Veatch, headquartered in Overland Park, Kan. Through the firms Grand Rapids office it provided planning, design, and construction engineering services for the citys $400 million program that eliminates combined sewer overflow (CSO) pipelines.
Located under Mary Waters Park, the storage units will help to control flooding and reduce the amount of total suspended solids (TSS) flowing directly into the Grand River. The work, which is the largest stormwater control project in Grand Rapids history, is part of the citys CSO project that began in 1988 and was completed in July 2015, three years ahead of a state-mandated deadline.
