This project was to construct a new intake structure for St. Louis County Water Company's, Central Plant No. 3, in St. Louis County, Missouri. The project included piledriving, concrete forming, underwater excavation and placement of riprap.
This water intake structure was initially constructed inside a temporary cofferdam until the top lift of wall pours and concrete cap rose above the sheetpile. Massman Construction Co. installed two 54 inch water pipes.
To allow the St. Louis County Water Company to supply additional water to the St. Louis Area in their high peak late summer season, Massman installed and provided temporary power to two of the five new pumps. Later in the year Massman completed the installation of the remaining pumps and the permanent control house with its electrical systems.
