UNSPSC 47101556: Water trough

A type of channel-type water holder that releases the upper water with the sedimentation of suspended solid from the settling pond or releases the washing water with the backwashing of filter layer from the filter paper.

UNSPSC 47101556 Water trough is a Commodity code that state and local governments interpret narrowly in practice — the recent opportunities show water and wastewater treatment authorities procuring chemical treatment systems, membrane filtration equipment, polymer feed systems, piping infrastructure, and control electronics for water production and reclamation facilities, not physical troughs themselves. The issuing bodies span state universities (Texas State University), county water utilities (Gwinnett County, Collier County), municipal water departments (City of Tampa, City of Phoenix, City of Waxahachie), transit and facility authorities (School Board of Seminole County, Eastern Municipal Water District), and regional water reclamation districts (Collin College, City of Calhoun). Repeat activity concentrates among Florida municipalities and counties (Tampa Convention Center, Collier County, Orange County, Palm Bay, Holly Hill, Winter Park, Sanford, Cumming, Flowery Branch) and Georgia counties and cities (Gwinnett County, Paulding County, Athens-Clarke County, LaGrange, Calhoun, Rome, Columbia County, Gray), with scattered activity across Texas, California, and Oregon. The work solicited is not troughs at all but rather treatment-plant upgrades, water-loop extensions, polymer blending units, reverse osmosis systems, SCADA modernization, compliance-driven PFAS removal, dissolved-solids management, bypass pumping services, and replacement parts for existing water-treatment infrastructure.

Recent opportunities reflect three dominant activity streams. First, municipalities and counties are procuring turnkey chemical and physical treatment system upgrades — Collier County's $3.29 million blend-tank improvement (IFB, bid due July 1, 2026), Orange County's $11.008 million ground-storage-tank and VFD replacement (IFB, due June 9, 2026), and the City of Calhoun's CMAR-delivered PFAS treatment plant upgrade (RFP, due July 30, 2026). Second, ongoing maintenance and parts supply contracts are steady across Gwinnett County (dewatering polymer, RFQ, due July 30, 2026), Collin College (water-loop extension design-build, due July 28, 2026), Tampa Convention Center (chilled-water treatment, ITB, due July 28, 2026), and Atlanta's Department of Watershed Management (hose pump parts and polymer blending units, pre-advertisement notice phase May 2026). Third, specialized technical services dominate: City of Phoenix's Sanitaire membrane diffusers contract (five-year term, IFB due July 2, 2026), Columbia County's pump maintenance RFP (due May 7, 2026), and City of Waxahachie's full-service chlorine dioxide generation program (RFP, due May 28, 2026, zero-CAPEX model). No recent opportunities match the code's literal name; the code's assignment to these solicitations appears to reflect a broad administrative categorization of water-system goods and is not predictive of what vendors will actually be asked to supply.
