NIGP 89007: Centrifuges, Water Treatment

NIGP 89007 Centrifuges, Water Treatment is an Item code encompassing equipment rental, service, repair, and parts supply for centrifuge systems deployed across municipal and county water and wastewater treatment infrastructure. State and local governments are procuring centrifuge mobile sludge dewatering units for rental across multiple treatment facilities, annual service and repair contracts for OEM-brand centrifuges (Andritz, Alfa Laval, Flottweg), and comprehensive parts-supply and maintenance programs structured as multiyear agreements. The buyer mix spans city water departments, county wastewater authorities, and municipal treatment utilities; issuing bodies include the City of Waxahachie (Texas), Hillsborough County Board of County Commissioners (Florida), the City of Salem (Oregon), and the City of Atlanta Department of Watershed Management (Georgia). The code also captures ancillary water-treatment services bundled with centrifuge operations, such as chlorine dioxide generation programs that combine equipment, chemical supply, installation, and ongoing technical support at municipal treatment plants.
