North River Wastewater Treatment Plant

The North River Centrifuge project includes building a new centrifuge facility at the North River Wastewater Treatment Plant in Manhattan. The project scope includes the installation of several pumps and piping systems, sewage grinders, chemical feed systems, tank farms, motor control center, bridge crane and a 54,000 lb centrifuge.

The North River plant is the latest of the 14 wastewater treatment plants throughout New York City and was built in the 1980s over the Hudson River. The City built one of the largest parks in Manhattan on top of the plant, which treats about 125 million gallons of wastewater every day and about three times as much whenever it rains. Of the city’s 14 wastewater treatment facilities, only eight have dewatering capabilities. At North River the sludge is currently loaded onto barges and sent to the Ward's Island plant for dewatering. This new centrifuge facility will improve the efficiency of the treatment process and reduce the number of barges required to transfer sludge to Ward's Island.
