UNSPSC 47101500: Water treatment and supply equipment

UNSPSC 47101500 Water treatment and supply equipment is a Class code covering the supply and installation of water treatment chemicals, systems, and equipment that state and local water and wastewater utilities procure to operate drinking water and treatment plants. Recent state and local solicitations show active procurement of water softener systems and controls, treatment chemicals (aluminum sulfate, chlorine, sodium hypochlorite, ferric sulfate, quicklime, citric acid, sodium bisulfite, magnesium hydroxide), polymer products for solids dewatering, specialized chemical feed and monitoring systems, and SCADA upgrades to water treatment facilities. Issuing bodies span water departments in cities and counties (Salt Lake County, North Texas Municipal Water District, Sarasota County, Tampa Bay Water, Collier County, Gwinnett County, the City of Santa Cruz, Caltrans, the City of Dallas, the California Department of Fish and Wildlife), towns (Stamford, Pepperell, Wareham, Edgartown), school districts (St. Mary's County Public Schools, Florida School for the Deaf and the Blind), state agencies (Massachusetts Water Department, California Department of Water Resources), and special-purpose authorities (MWRA, Great Lakes Water Authority, Central Florida Tourism Oversight District).

Recent opportunities cluster in California, Florida, Georgia, Texas, Massachusetts, Connecticut, Michigan, and Utah. Representative recent solicitations include Salt Lake County's RFB for water softener removal and replacement at Mountain America Exposition Center (due August 5, 2026); Collier County's IFB for lime softening improvements and blend tank construction with a $3.29 million budget (due July 1, 2026); Gwinnett County's competitive bid for solids dewatering and thickening polymer on a four-year contract beginning October 2026 with bench and full-scale testing required by July 22; the City of Santa Cruz Water Department's IFB for liquid aluminum sulfate with estimated annual expenditure of $130,000 and orders every 1–2 weeks; Caltrans' IFB for HVAC hydronic water testing across nine California counties with mandatory 3% DVBE and 25% small-business participation goals (due June 30, 2026); Tampa Bay Water's three separate ITBs for liquid ammonium sulfate, sodium hypochlorite, ferric sulfate, and quicklime (all due June 30, 2026); and the Massachusetts Water Resources Authority's construction contract for sodium hypochlorite chemical feed system upgrades at Brutsch Water Treatment Facility with an estimated cost of $983,000 (due June 23, 2026). Most competitive procurements run one to four years with renewal options, emphasize NSF 60 or AWWA certification compliance, require delivery within 48 to 72 hours of order, and award to lowest responsive and responsible bidders. Set-asides and preferences appear in some jurisdictions (DVBE participation, small-business goals, local vendor preferences) but vary by issuing body and procurement.
