UNSPSC 47101539: Sludge or sewage removal equipment

UNSPSC 47101539 Sludge or sewage removal equipment, a Commodity code, covers replacement drive shafts, pumps, clarifiers, thickener mechanisms, gates, and related mechanical components that state and local governments procure for wastewater and water treatment facility operations. Recent solicitations show municipalities and special districts purchasing replacement mechanisms for clarifiers and thickeners (often as capital projects involving equipment removal, installation, and startup), OEM-branded replacement parts (pumps, valves, mixers, gates, blowers), drive units for treatment processes, and ancillary hardware such as polymeric chains for treatment mechanisms. Issuing bodies span city water departments (Holly Hill and Phoenix, Arizona), county-level water authorities (Macon Water Authority, Gwinnett County Department of Financial Services), state water agencies (California Department of Water Resources), and municipal utilities (Salt Lake City Department of Public Utilities). Utilities and water reclamation facilities are the dominant buyer type, often procuring through IFBs, RFPs, or informal quotes when replacement parts are standardized or sole-source.

Geographic activity concentrates in the Southeast and West, with recent opportunities from Florida, Georgia, Arizona, California, Maryland, and Connecticut. The City of Phoenix issued an IFB for vactor services (vacuum truck, jet rodding, hydro-blasting) across multiple treatment plants with a response date of October 19, 2026 and a DBE-N compliance requirement. The Macon Water Authority posted an IFB for rebuild of three 75-foot thickeners and clarifier #6 with a mandatory pre-bid meeting on October 6, 2026 and bids due October 20, 2026. The City of Holly Hill, Florida executed a sole-source procurement for a WesTech DS43 drive shaft replacement ($113,067.00 total) through its water treatment plant capital project. Salt Lake City requested qualifications for gas purification scrubber equipment installation at its Water Reclamation Facility. The California Department of Water Resources and Maryland Environmental Service both solicit ongoing services for equipment inspection, maintenance, and replacement across multiple facilities. Contract structures vary from fixed-price equipment purchases to time-and-materials service agreements, requirements contracts, and multi-step sealed bids; most include prevailing wage, set-aside, or preference provisions where applicable.
