UNSPSC 47101551: Up flow filter

A filtering device that has the natural water flowing into the lower part of the tank and filtered to upper direction, and when filtered, the foreign substance arrested is lifted up by the air to release outside. At this time, the filter sand placed upwardly together with the impure substance is washed off and it is dropped to the filter layer again by washing and its own weight.

UNSPSC 47101551 Up flow filter, a Commodity code, does not align with the recent state and local procurement activity tagged under it. The source records 29 recent solicitations, none of which involve filtration equipment or the water-treatment components the code nominally describes; instead, they document requests for water and wastewater parts, chemical treatment systems, pumping and grinder equipment, instrumentation, SCADA controls, and construction services across municipal water districts. The code shows little relevant recent activity and the opportunities posted do not reflect the product category.

State and local water agencies—including cities (Pompano Beach, Phoenix, Tampa, Atlanta, Waxahachie, Flowery Branch, Calhoun, Sanford), counties (Collier, Gwinnett, Orange, Marion, DeKalb, Paulding, Bell, Bartow), school districts (Marion County and Frisco ISDs), and regional authorities (Sacramento County Water Agency, West Travis County Public Utility Agency)—are actively procuring water and wastewater operations and capital improvements across the Southeast, Texas, and California. Collier County and Gwinnett County appear frequently, issuing multiple ITBs and RFPs for chemical treatment, pump station work, and facility upgrades. Recent representative solicitations include Collier County Board of County Commissioners requesting countywide chemicals for water treatment (ITB 268705, due November 13, 2026) covering 29 line items including ammonia, chlorine, and polymers with approximately $4 million annual spending; City of Pompano Beach requesting bids for Water Treatment Plant Phase 1 nanofiltration facility buildout (ITB27-001, due November 2, 2026) with prime contractor experience requirements on $20 million-plus membrane treatment projects; and Gwinnett County requesting sealed bids for bypass pumping services on annual contract (ITB BL145-26, due October 23, 2026) with pricing for pump sizes 4-inch to 12-inch and labor rates. No recent opportunities under this code actually procure up flow filter equipment or related filtration components. State and local procurement activity under code 47101551 remains inactive for its intended scope.
