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 (Commodity) names equipment that state and local governments purchase primarily for water treatment plant operations—replacement drive shafts, aeration systems, grinder components, and ancillary mechanical and instrumentation parts that support the continuous operation of municipal water and wastewater facilities. Recent solicitations reveal that the code is heavily concentrated in proprietary replacement parts and OEM equipment integration, driven by the specialized nature of existing infrastructure; state and local buyers frequently pursue sole-source procurements when replacement components are engineered to integrate with installed systems from original manufacturers such as WesTech, Xylem, Chemco, and Andritz.

State and local issuing bodies soliciting under this code span cities, counties, and utilities across Florida, Georgia, Texas, and other states. The City of Holly Hill, Florida appears as a repeat buyer, issuing multiple sole-source notices in 2026 for drive shaft replacement (WesTech DS43 Dual Shaft unit, $113,067, IFB SS202001 with September 2020 response date now closed), Flygt OEM parts and pumps (Xylem Water Solutions, sole-source notice 26PWSS09 posted October 19, 2026), lime slaking systems (Chemco Systems LP, sole-source notice 26PWSS10 posted October 19, 2026), and specialized belt press components (Andritz Separation Inc., sole-source notice 26PWSS11 posted October 19, 2026). Collier County (Florida) issued a countywide chemicals ITB (268705, responses due November 13, 2026) covering 29 chemical line items across water and wastewater treatment with approximately $4 million annual county spending, while Gwinnett County (Georgia) and the City of Atlanta (Georgia) solicited wastewater equipment parts including grinders, polymer blending units, and bypass pumping services. Phoenix, Sacramento, Tampa, and other municipalities pursued competitive bidding for instrumentation, diffusers, and pressure-temperature equipment. The code shows broad geographic activity concentrated in Florida, Georgia, and Texas, with less frequent but persistent procurement across the rest of the continental United States.
