NIGP 89085: Water Softening Equipment, Ion Exchange Type (Also See 670-92,93)

NIGP 89085 Water Softening Equipment, Ion Exchange Type is an Item code covering ion exchange softening systems, replacement components, and associated installation and maintenance services that state and local water utilities, school districts, and municipalities procure to reduce hardness and improve water quality at treatment plants, wellfields, and facility point-of-use locations. Recent solicitations show governments buying complete softening systems with dual-shaft drives and motor assemblies, ASME-stamped pressure vessels for lead-lag PFAS removal configurations, replacement drive shafts for existing equipment, and monthly water sampling and analysis services to verify system performance. Issuing bodies include municipal water departments (City of Holly Hill, Town of Prescott Valley, City of LaGrange, Tampa Bay Water), county water authorities (Gwinnett County, North Texas Municipal Water District), school districts (Dallas Independent School District, Marion County School Board), and regional water supply authorities. Water treatment represents the dominant category of recent procurement activity, though school food-service operations also appear as a secondary market segment.
