Centrisys Corporation, a leading North American manufacturer of decanter and thickening centrifuges and dewatering systems, announced in February that it has secured a contract with the New York City (NYC) Department of Environmental Protection to provide maintenance and repairs for eighty-three existing decanter centrifuges located in eight New York City wastewater treatment facility locations. Centrisys’s contract was bid in partnership with Jett Industries, Inc.; a leading general contractor focused on constructing and modifying water and wastewater treatment facilities.


“Aligning with Centrisys in the contract bidding process to support New York City’s wastewater treatment facilities allowed us to bring all of our collaborative strengths to the table to ensure we provided recommendations that offer facility efficiencies and an innovative problem-solving approach,” says Kevin Miedreich, project manager with Jett Industries, Inc. “The cooperative arrangement allows our team to lean on our in-depth knowledge of facility processes and expedite lead times.”

The NYC wastewater treatment facility locations included in Centrisys’s maintenance and repair contract are as follows:

  • Bowery Bay, Upper East River, Queens: four CP4-1 centrifuges
  • Newton Creek, East River, Brooklyn: twenty-four BSC3114 thickeners
  • Oakwood Beach, NYC Bay, Staten Island: four CP4-1.1 centrifuges
  • Red Hook, East River, Brooklyn: two SC3-3 centrifuges
  • North River, Hudson, New York: one BSC5-2 centrifuge
  • 26th Ward, Jamaica Bay, Brooklyn: sixteen CP4-1 centrifuges
  • Wards Island, Upper East River, New York: sixteen CS26-4 2PH centrifuges
  • Hunts Point, Upper East River, Bronx: sixteen CS26-4 2PH centrifuges


New York City manages fourteen wastewater resource recovery facilities that treat 1.3 billion gallons of wastewater daily. The treatment system consists of over 6,000 miles of sewer pipes, 135,000 sewer catch basins, over 495 permitted outfalls for the discharge of combined sewer overflows, and ninety-five wastewater pumping stations that transport to the wastewater resource recovery facilities located throughout the five boroughs. New York City’s sludge is digested and transformed to biogas. After digestion, the leftover solids are then dewatered.


Centrisys has built a remarkable relationship with the New York City Department of Environmental Protection as we have collaborated on significant projects together in recent years. In 2020, we announced the installation of thirty-two American-made CS26-4 Centrisys decanter centrifuges at New York City’s largest wastewater treatment plants. We appreciate their trust in our team and look forward to further supporting New York City with our maintenance and repair expertise in the years ahead.
