UNSPSC 72154007: Dewatering service

The dewatering of property owned by others

UNSPSC 72154007 Dewatering service, a Commodity code, covers the removal and management of water from sludge, biosolids, and construction sites — work that state and local water utilities, wastewater treatment plants, and public works departments procure to meet environmental compliance, operational efficiency, and site-restoration standards. Recent solicitations show municipalities buying centrifuge and rotary-press systems for biosolids dewatering at treatment plants, sludge removal and dewatering from treatment-plant lagoons, construction dewatering during water-main replacement and retaining-wall projects, and maintenance and repair services for existing dewatering equipment at pump stations. Issuing bodies span municipal utilities departments, county wastewater authorities, and cities with their own water-reclamation facilities; the City of Ocala Water Resources Department, City of Hartwell Georgia, Seminole County Utilities Department, and the City of Casselberry each appear as repeat or multi-project buyers. Vendor qualification thresholds are steep: many solicitations require ten years of documented experience designing and installing centrifuges or rotary presses, completion of at least three similar projects with evidence of work scope, OSHA 10/30 or equivalent safety training, and responsibility for all permitting. Mandatory pre-bid meetings or site visits are standard, and turnkey installation with performance bonding (often 100 percent of contract value plus separate three-year maintenance bonds) is the norm for equipment procurement.

Recent activity concentrates in Florida, where the City of Ocala (ITB WRS/260503 for centrifuge installation at WRF #3 with mandatory pre-bid March 19, 2026, and bid due April 7, 2026; ITB WRS/260536 for rotary-press installation at WRF #2 with mandatory pre-bid March 19, 2026 at 11:00 a.m. and bid due April 8, 2026), the City of Casselberry (IFB for water-main replacement involving dewatering and erosion control, $9.36 million engineer's estimate, bid due August 6, 2026), Seminole County (CC-7100-26 wastewater pump-station repair and refurbishment, bid due June 17, 2026, renewed as CC-7100-26/HSM with August 5, 2026 deadline), and the City of DeBary (irrigation system replacement at Rob Sullivan Park, $90,000 engineer's estimate) demonstrate sustained municipal capital and maintenance spending. Georgia buyers include the City of Hartwell (alum-sludge removal and disposal, 3,315 cubic yards, bid due July 28, 2026). Maryland, Connecticut, and California jurisdictions also posted dewatering-adjacent work — Worcester County, Maryland (Ocean Pines biosolids dewatering, bid due September 10, 2026), Town of Groton, Connecticut (community-center irrigation installation, bid due July 9, 2026), and the City of Long Beach, California (retaining-wall repair involving site dewatering, bid due October 13, 2026) — indicating regional diversity. The code sees consistent activity across municipal water infrastructure modernization, biosolids management, and construction-support services, with bid cycles and performance requirements that favor established firms with capital equipment, bonding capacity, and a track record in municipal utility work.
