UNSPSC 23152102: Stationary separation equipment or parts or screens

UNSPSC 23152102 Stationary separation equipment or parts or screens, a Commodity code, encompasses water treatment plant equipment including drive shafts for clarifier and softener units, aeration systems, and associated components that state and local governments procure for drinking-water and wastewater treatment operations. The work solicited under this code involves replacement, installation, and maintenance of proprietary mechanical separation and aeration equipment integrated into existing treatment-plant infrastructure. Issuing bodies include municipal water departments (City of Holly Hill, Florida), county utilities departments (Hillsborough County, Clayton County, and Columbia County in Georgia), and regional water authorities. Sole-source procurements dominate the recent activity, reflecting the specialized nature of replacement parts and compatibility requirements with existing installed systems.

Recent solicitations cluster in Florida and Georgia. The City of Holly Hill issued a sole-source Notice of Intended Decision (posted October 19, 2026) for a WesTech DS43 Dual Shaft Drive replacement unit and turnkey installation at its Water Treatment Plant, valued at $113,067.00. Hillsborough County posted a sole-source procurement notice (September 8, 2026, due September 22, 2026) for installation and maintenance of Wet Well Wizard aeration systems across 60 to 80 units annually over five years (2027–2032) at an estimated total contract value of $5.371 million, restricted to Agora Water Solutions LLC as the sole provider and patent owner. Clayton County and Columbia County both issued RFPs (posted July 1, 2026, due July 30, 2026) for drinking-water treatment residuals removal and disposal at two treatment plants each—the Jim Blanchard Water Treatment Plant and the Clarks Hill Water Treatment Plant. These procurements signal ongoing capital renewal and maintenance spending in municipal water systems, with preference for vendors holding exclusive manufacturing or service-provider status for installed equipment.
