UNSPSC 41104201: Water purification reagents

UNSPSC 41104201 Water purification reagents is a Commodity code covering chemical treatment products and services for municipal and institutional water systems, including polymers for solids dewatering, activated carbon, treatment chemicals for cooling loops and recirculating systems, and lime slaking systems. State and local buyers under this code span water utilities, wastewater treatment agencies, municipalities, school districts, and special-purpose facilities; issuing bodies include city water departments, county boards of commissioners, school boards, and universities. Work is predominantly reactive or scheduled maintenance and replacement—municipalities procure annual supplies of standardized treatment chemicals (aluminum sulfate, sodium chlorite, liquid chlorine, caustic soda, ferric chloride), while larger facilities bid treatment services contracts with performance requirements tied to system-specific applications. Solids-handling polymers dominate the wastewater utility segment, with specification requirements for bench-scale and full-scale testing before approval. Recent opportunities show issuing bodies contracting both product supply and professional service delivery; the School Board of Seminole County, for example, sought licensed water treatment contractors across 50 school locations on a multi-year services basis, while cities and counties separately procure discrete chemical commodities on annual or multi-year cycles. Sole-source notices appear when customers integrate proprietary equipment (Xylem Flygt pumps, Chemco lime slaking systems) that lock procurement to OEM parts and authorized service providers.

Geographic activity concentrates in Georgia and Florida, with recent postings from the City of LaGrange, City of Griffin, Gwinnett County Board of Commissioners, School Board of Seminole County, the Cities of North Las Vegas and Holly Hill, and the City of Dallas. The Tampa Convention Center and University of Connecticut also posted recently. Representative recent opportunities include the Gwinnett County Board of Commissioners' ITB for solids dewatering and thickening polymer (due July 30, 2026) specifying pre-approved product Polydyne Clarifloc SE-1748 with four-year contract and four one-year renewal options at multiple water reclamation facilities; the City of LaGrange's sealed-bid solicitation for eight chemical items including powdered activated carbon, liquid aluminum sulfate, and sodium bisulfite (due June 8, 2026) with firm pricing for twelve months and two-day delivery windows; the Tampa Convention Center's bid for comprehensive chilled water and cooling tower treatment services (due July 28, 2026) with data-driven programs and performance efficiency targets; and the School Board of Seminole County's ITB for licensed contractor services on 50 school campuses (closed March 31, 2026) with monthly fixed rates and hourly emergency service pricing, where the Notice of Intended Decision named Premier Water & Energy Technology, Southern Waters Company Incorporated, and SWE, Inc. as responsive vendors under consideration.
