UNSPSC 47101504: Bacterial removal equipment

UNSPSC 47101504 Bacterial removal equipment, a Commodity code, encompasses water treatment chemicals, systems, and services that state and local water utilities, municipal treatment plants, school districts, and transit authorities procure to manage bacterial contamination, corrosion, scale, and biological growth in potable water, chilled water, and cooling tower systems. Recent solicitations show state and local buyers purchasing chemical treatment programs (chlorine, caustic soda, sodium hypochlorite, polymers, and specialty feed systems), maintenance and monitoring services, equipment replacement and installation, system inspections and commissioning, and residuals removal and disposal across treatment plants, distribution infrastructure, and facility cooling systems. The issuing bodies include county water departments, city utilities, water reclamation facilities, state agencies overseeing regional water projects, school districts, and independent special-purpose districts operating water or cooling infrastructure. Representative recent solicitations include Dallas Independent School District's RFP for district-wide water treatment services (due October 15, 2026) with a three-year base term and two optional one-year renewals, carrying a Small Business Enterprise participation goal of 30 percent; DeKalb County School District's RFP 27-812 for HVAC water treatment services across 98 facilities (due October 22, 2026); and the California Department of Water Resources' IFB 10214188 for comprehensive water treatment system services across four field divisions (bids due June 9, 2026).

Recent activity concentrates in Florida, Georgia, California, and Texas. Collier County, Florida has posted multiple opportunities including a Notice of Intent to single-source chilled water treatment services from Nalco/Ecolab (challenge period September 11, 2026) and a sealed-bid construction project for lime softening improvements and a blend tank at the South County Regional Water Treatment Plant (bids due September 21, 2026, estimated value $4.27 million). Clayton County and Columbia County in Georgia are each seeking proposals for drinking water treatment residuals removal and disposal at two treatment plants (both due July 30, 2026). The City of Tallahassee issued RFP for power plant chemical treatment programs at two generating stations (due August 31, 2026), and the City of LaGrange, Georgia solicited sealed bids for eight water treatment chemicals including powdered activated carbon, aluminum sulfate, sodium chlorite, and caustic soda for fiscal 2026–2027 (bids due June 8, 2026). The Tampa Convention Center solicited bids for comprehensive chilled water and cooling tower treatment services emphasizing data-driven programs and measurable efficiency gains. Bell County, Texas issued bids for conventional water treatment plant filter gallery modifications including sandblasting, recoating, and chemical injection point reconfiguration (due August 25, 2026, engineer's estimate $2.25 million). Riverside County, California requested quotes for iron and manganese filter media replacement (due July 31, 2026). SBE and DVBE set-asides appear in school district and state procurements; sole-source and manufacturer-exclusive procurements are common when existing infrastructure dictates vendor continuity.
