UNSPSC 12165200: Water treatment

Water treatment including potable water, desalinization water, and deionized water.

UNSPSC 12165200 Water treatment (Class) encompasses the supply of treatment chemicals, equipment maintenance, and specialized services that state and local water and wastewater utilities deploy at treatment plants and distribution facilities. Recent state and local solicitations show municipalities and regional water districts buying aluminum chlorohydrate sulfate coagulants, sodium hypochlorite, sulfuric acid, ferric sulfate, polymer blends, and lime softening system components; contracting for membrane diffuser replacement, traveling screen repairs, centrifuge parts and service, polymer blending unit maintenance, and byproduct residuals removal and disposal; and procuring laboratory testing, SCADA upgrades, cooling tower treatment, diving services for submerged infrastructure inspection, and full-service facility operations contracts. The issuing bodies span city water and wastewater departments (Scottsdale, Phoenix, Bradenton, Atlanta, Santa Cruz, St. Marys, Calhoun, Meriden), county water resources and environmental services offices (Beaufort, Collier, Clackamas, Clayton, DeKalb, Gwinnett, Hillsborough, Orange County Florida, Seminole, Pinal), state environmental and water agencies (Maryland Environmental Service, Oregon, Massachusetts Department of Environmental Protection, New Mexico Water Systems), and special-purpose water districts (Eastern Municipal Water District, Central Florida Tourism Oversight District, Tampa Bay Water).

Activity concentrates in Florida, Georgia, and California, with secondary representation in Arizona, Oregon, North Carolina, Texas, Massachusetts, and Connecticut. Representative recent solicitations include the City of Scottsdale's RFP 27RFP092 for aluminum chlorohydrate sulfate coagulant supply due August 5, 2026; the City of Phoenix's IFB 27-FMD-013 for three-year cooling tower water treatment services with contract start October 1, 2026; the City of Bradenton's IFB 26039NT for sedimentation basin and flocculator rehabilitation with bids due August 7, 2026 and a $300,000 owner's allowance for unforeseen conditions; Collier County's bid 26-8683 for $3.29 million SCRWTP lime softening improvements with bids due July 1, 2026 (note: one source entry shows past due date; bid status requires verification); and Orange County Florida's sealed bid Y26-748 for $14,314,240.85 SCADA upgrades and PLC replacements at East Water Reclamation Facility with bids due July 28, 2026. Pricing structures vary from unit-cost chemical supply contracts to fixed-price multi-year service and equipment agreements. Many opportunities target professional qualifications including NSF/ANSI 60 certification for chemical suppliers, manufacturer authorization for equipment service (SNF Polydyne, Heartland, Parkson, Sanitaire), and specialized certifications such as ISO 9001 for laboratory operations and ACS certification for analytical chemistry.
