UNSPSC 47101525: Dewatering equipment

UNSPSC 47101525 Dewatering equipment, a Commodity code, encompasses consumable chemicals, treatment polymers, specialized parts, and maintenance services that state and local water utilities deploy to reduce solids in wastewater and drinking water treatment. Recent solicitations show purchasing activity focused on polymer application for belt filter presses and centrifuges, reverse osmosis and deionized water system maintenance, chilled water loop chemical treatment, lime softening systems, and wastewater bar screen and grit removal installations. Water districts, municipal water departments, counties, college utilities, and special-purpose authorities issue the bulk of RFP, RFQ, and IFB notices under this code, with repeat activity from Gwinnett County (Georgia), Collier County (Florida), Collin College and Texas State University (Texas), the City of Tampa (Florida), and the City of Phoenix (Arizona). Geographic concentration appears strongest in Florida, Georgia, and Texas, though recent opportunities also surface in California, Maryland, and the Pacific Northwest.

Representative recent activity includes Gwinnett County's July 2026 solicitation for solids dewatering and thickening polymer (IFB due July 30, 2026) for three wastewater facilities with a four-year initial term and four optional one-year renewals; Tampa Convention Center's July 2026 RFQ for comprehensive chilled water and cooling tower treatment services (due July 28, 2026) emphasizing data-driven chemical feeds and water savings; the City of Waxahachie's May 2026 RFP for a full-service chlorine dioxide generation program at two water treatment plants (due May 28, 2026) with zero-CAPEX equipment ownership model and a two-year initial term plus up to eight annual renewals; and Collier County's April 2026 sealed bid for SCRWTP Lime Softening Improvements—Blend Tank (estimated $3.29 million, due July 15, 2026) covering chemical systems installation in an operating drinking water plant. Purchasing activity is consistent and wide-ranging across treatment modalities and facility types, with strong incumbent-protection dynamics in sole source and notice-of-intent-to-award procurements that dominate the competitive landscape.
