UNSPSC 23152111: Woven wire vibratory separation screen

Separation equipment screen made of woven wire

UNSPSC 23152111 Woven wire vibratory separation screen is a Commodity code under which state and local governments procure mechanically cleaned wastewater and water treatment screens, drive systems, and ancillary equipment for removal and separation of solids from influent streams at municipal water and wastewater treatment plants. Recent solicitations show water and wastewater utilities buying complete screen assemblies with specified aperture sizes (such as 6-millimeter openings), mechanical cleaning mechanisms, drive units with dual-motor systems and torque control, spray-wash components, and replacement parts for existing treatment infrastructure. Issuing bodies include county water authorities, municipal water departments, and state environmental services agencies responsible for operating public water and wastewater treatment facilities. Georgia counties (Clayton County and Columbia County) and the Maryland Environmental Service have solicited under or near this code for drinking water residuals removal services and mechanically cleaned wastewater screens; Florida municipalities also appear in the recent activity, though one sourcing was a sole-source replacement procurement outside standard competitive procurement.

Geographic activity concentrates in Georgia and Maryland, with recent solicitations posted in June and July 2026. Clayton County, Georgia issued RFP 2026025-RFP5105 for drinking water treatment residuals removal and disposal at two treatment plants (Jim Blanchard Water Treatment Plant in Martinez and Clarks Hill Water Treatment Plant in Appling), with proposals due July 30, 2026. The Maryland Environmental Service solicited competitive sealed bids (IFB 1262595) for supply and delivery of a mechanically cleaned wastewater screen with a 6-millimeter opening at the Dorsey Run Wastewater Treatment Plant in Jessup, Anne Arundel County, Maryland, due May 28, 2026, requiring mandatory site visits in early May and a pre-bid conference. Both opportunities demand detailed technical specifications, equipment certifications, references from operating facilities, and compliance with state procurement and nondiscrimination requirements. Bidders typically face lead times of 12–14 weeks for equipment manufacturing and must provide installation support, operator training, operation and maintenance manuals, and warranty coverage.
