UNSPSC 47101572: Disc screen

A type of device that releases the sold matter to be screened while the flowing water passes to the rotating and empty disc-type of screen to purify.

UNSPSC 47101572 Disc screen (Commodity) covers replacement parts and equipment for water treatment and wastewater system applications—specifically drive shafts, grinders, polymers, sensors, instrumentation, and chemical feed system components—that state and local governments procure to maintain operational continuity of municipal water and wastewater treatment facilities. State and local buyers under this code span water utilities (city water departments, county water resources divisions, regional water authorities), wastewater treatment operators, school districts managing food service water quality, and convention centers requiring chilled water treatment. Within the recent solicitation record, the City of Holly Hill, Florida, has issued multiple sole-source notices for proprietary equipment replacement (WesTech drive shafts, Xylem Flygt pump parts, Chemco lime slaking systems, and Andritz belt press components), establishing a pattern of repeat buying driven by installed-base lock-in. Collier County, Florida has procured countywide chemicals and lime softening improvements across multiple treatment plants. Gwinnett County, Georgia; Atlanta; and Phoenix have solicited polymer, grinder parts, membrane diffusers, and instrumentation in competitive and sole-source formats. Geographic activity concentrates in Florida (Holly Hill, Collier, Winter Park, Tampa, Pompano Beach), Georgia (Gwinnett, Atlanta, Calhoun, Athens-Clarke, Paulding), and Arizona (Phoenix), with secondary activity in Texas (Waxahachie, McKinney, Austin, Bell County, Calhoun) and scattered regional demand.

Recent representative opportunities illustrate the code's scope: the City of Holly Hill issued Solicitation SS202001 (sole source, September 22, 2020 adoption, later reopened) for a WesTech DS43 Dual Shaft Drive unit and turnkey installation for softener #2 replacement at a water treatment plant, valued at $113,067.00; Collier County issued ITB 268705 (due November 13, 2026) for countywide water treatment, wastewater, and parks chemicals across 29 line items (ammonia, chlorine, sodium hydroxide, polymers) with approximately $4 million in historical annual spending and a local-vendor preference; the City of Phoenix issued IFB 260382 (due July 2, 2026) for Sanitaire membrane diffusers and replacement parts for two wastewater treatment plants on a five-year term; Gwinnett County issued BL145-26 (due October 23, 2026) for annual bypass pumping services with equipment and labor rates; and Collin County issued 268705 (due July 9, 2026) for water and wastewater parts and supplies. Sole-source procurement appears in approximately 40 percent of recent activity, driven by proprietary equipment compatibility and manufacturer-exclusive OEM parts availability. Competitive bids and RFQs are common where off-the-shelf chemicals, standard instrumentation, or multi-vendor alternatives exist. No set-asides for disadvantaged enterprises dominate; a few jurisdictions (City of Phoenix, Collier County) apply local-vendor or SBE preferences. Contract terms typically run one to five years with renewal options. Activity intensity suggests sustained demand for replacement parts, chemical supply, and system upgrades to support aging water and wastewater treatment infrastructure, with municipal PFAS compliance and system modernization driving capital and operational spending.
