Competing with nine other contractors, Mosites Construction Company won the competitive bid award for construction of a new water treatment plant in McKeesport, PA

The plant's location adjacent to the Youghiogheny River presented numerous challenges, since much of the construction had to be done below river level with excavations made down to 15 feet below the river pool.

Mosites first constructed cofferdams driven sheet piling then dewatering. Next, Mosites built massive concrete foundations that included concrete tanks and channels. Then Mosites utilized various concrete forming systems to construct walls, piers, elevated slabs, beams, columns and weirs to finish complete cast-in-place structure.

Mosites also coordinated the intricate instrumentation and mechanical systems to bring the McKeesport Plant on line.

With a system capacity of 10 million gallons per day, the plant now operates on a completely automated and computerized processing system, supplying water to the McKeesport area.
