Tarlton Diverts 96-inch Pipe in St. Louis Wastewater Project
MSD tapped Tarlton in 2007 as general contractor for the $87 million, 30-month Lemay project, which will increase the peak wet-weather treatment capacity of the plant. Tarlton’s work includes tunneling, 12-foot-diameter sewer piping, construction of four primary clarifiers, two grit basins, a primary sludge pump station, grit handling building and numerous cast-in-place vaults, the deepest being 74 feet underground. Completion is scheduled for early 2010.
