Abstract:
Construction on what may be the largest concrete caisson in the United States will soon be completed in Detroit, Michigan. The self-sinking, 140 ft diameter, 82 ft tall circular caisson will house seven pumps, each capable of moving 107 million gal per day of raw sewage. Walbridge Aldinger is the general contractor constructing the caisson as part of an expansion of the Detroit Water and Sewerage Department's (DWSD) Wastewater Treatment Plant.
