UNSPSC 47101504: Bacterial removal equipment

UNSPSC 47101504 Bacterial removal equipment (Commodity) encompasses water treatment chemical systems, polymer products, and associated services that state and local water utilities, convention centers, and school districts procure to control biological growth and corrosion in chilled water loops, cooling towers, treatment clarifiers, and distributed potable water systems. Recent solicitations show procurement of chilled water treatment programs combining chemical feed equipment and monitoring technologies; solids dewatering and thickening polymers for belt filter presses and centrifuges; water treatment residuals removal from settling ponds; and grease interceptor maintenance and inspection to prevent biological fouling. Issuing bodies include municipal water departments (Tampa Convention Center, City of LaGrange, City of Cumming), county water utilities (Collier County, Gwinnett County, Clayton County), state water agencies (California Department of Water Resources), and school districts (Seminole County). Several repeat buyers appear across the recent opportunities block—Seminole County School Board and Georgia water systems appear multiple times—suggesting sustained demand for treatment services and chemical inputs.

Recent activity concentrates in the Southeast, particularly Georgia and Florida, with secondary activity in California and Virginia. Representative opportunities include Collier County's invitation to bid for lime softening improvements and blend tank construction at the South County Regional Water Treatment Plant (Bid 26-8683, due July 1, 2026, $3.29 million budget); Gwinnett County's competitive sealed bid for solids dewatering and thickening polymer on a four-year annual contract for three water reclamation facilities (due July 30, 2026); Clayton County's RFP for drinking water treatment residuals removal and disposal at two plants (due July 30, 2026); and the Tampa Convention Center's bid solicitation for comprehensive chilled water and cooling tower treatment services with data-driven monitoring and chemical feed equipment (due July 28, 2026, with SBE participation component). The California Department of Water Resources issued a broader IFB for comprehensive water treatment system services across twelve facilities in Byron, Gustine, Bakersfield, and Pearblossom (due June 9, 2026, with mandatory pre-bid May 26, three-year initial term plus two optional renewal years, requiring Class A General Engineering Contractor license and minimum 3 percent DVBE participation). Municipal and county water systems are the dominant customer class, with treatment chemical procurement, residuals management, and system maintenance representing the core work.
