UNSPSC 47101570: Oxidation ditch

A bio-chemical reactor that disassembles the polluted substance by supplying the oxygen with the mechanical aerator to the elliptical reaction vessel.

UNSPSC 47101570 Oxidation ditch is a Commodity code that names a single treatment technology within wastewater and water infrastructure work. The recent opportunities tagged with this code do not reflect oxidation ditch procurement; instead they span water and wastewater treatment operations, chemical supply, parts procurement, and system upgrades across municipal and county utilities. State and local governments buying under this code in practice are securing reverse osmosis and deionized water system maintenance (Texas State University), chilled water loop extensions and treatment services (Collin College, Frisco ISD, Seminole County schools), lime softening improvements and blend tank construction (Collier County, Florida), solids dewatering polymers (Gwinnett County, Georgia), wastewater bar screens and screening systems (Paulding County, Georgia; multiple Florida counties), membrane diffusers and fine bubble aeration equipment (Phoenix, Tampa), treatment plant upgrades and SCADA modernization (multiple Georgia and Florida municipalities), and specialized parts for Flygt pumps, Bredel hose pumps, SNF Polydyne polymer blending units, and JWCE grinders across water reclamation facilities.

Issuing bodies include state university systems, independent school districts, county water utilities and departments of water resources, municipal water departments, and regional water reclamation facilities in Texas, Georgia, Florida, Arizona, and California. Gwinnett County (Georgia) appears repeatedly as a buyer of polymer products, bypass pumping services, and water system components on annual contracts with renewal options. Representative recent opportunities include Gwinnett County's competitive sealed bid for solids dewatering and thickening polymer (due July 30, 2026, with mandatory bench-scale testing by July 22); the City of Tampa's RFQ for chilled water loop treatment services at the convention center (due July 28, 2026); Collier County's IFB for lime softening improvements with a 3.29 million dollar budget (due July 15, 2026, with pre-bid June 9); and the City of Waxahachie's RFP for a full-service chlorine dioxide generation program covering two treatment plants at 9 and 10 MGD capacity (due May 28, 2026). Activity clusters in Florida (Collier, Hillsborough, Seminole, Orange, Volusia counties and multiple municipalities), Georgia (Gwinnett, Columbia, Athens-Clarke, Calhoun, Cumming, Rome, Effingham), and Texas (Waxahachie, Huntsville, Tucson Arizona); smaller numbers of procurements appear in California (Eastern Municipal Water District) and across the Southeast through water reclamation and treatment facility upgrades. The code's nominal focus on a single treatment device masks the actual purchasing pattern: state and local water utilities are routinely procuring integrated systems, maintenance contracts, replacement parts, and service expertise for the full spectrum of potable and wastewater treatment infrastructure rather than oxidation ditches specifically.
