UNSPSC 72154007: Dewatering service

The dewatering of property owned by others

UNSPSC 72154007 Dewatering service is a Commodity code describing the mechanical removal and processing of water from excavated materials, sludge, and sediment at water and wastewater infrastructure sites. State and local governments procure dewatering under this code as a component of broader utility maintenance, rehabilitation, and capital projects—primarily through county utilities departments, municipal water and wastewater agencies, and special-purpose water districts. Recent solicitations show dewatering bundled with pump station repair, sewer system rehabilitation, dredged material recovery, and biosolids processing, where contractors supply pumping equipment, operator labor, filtration or polymer treatment, and disposal coordination. Issuing bodies include county utilities (Seminole County, Florida), city water and wastewater departments (Ocala, Palm Bay, Santa Cruz, California), state environmental agencies (Maryland Environmental Service), and regional water districts (Eastern Municipal Water District, California). The code spans work from emergency dewatering at active construction sites through multi-month biosolids-recovery operations at treatment facilities.

Geographic activity concentrates in Florida (Seminole County, Ocala, Palm Bay, and the Central Florida Tourism Oversight District) and California (Santa Cruz, Riverside County), with secondary activity in Georgia, Maryland, and the Northeast. Representative recent opportunities include Seminole County Board of County Commissioners' Wastewater Pump Station R & R (IFB CC710026HSMA, due August 5, 2026), specifying dewatering as one of 18 integrated service scopes within a master service agreement for pump station maintenance and rehabilitation; City of Hartwell, Georgia's alum sludge removal and disposal from its Water Treatment Plant (sealed bid PE63460NONST2026000000010, due July 28, 2026), requiring dredging and dewatering of 3,315 cubic yards of material to paint-filter compliance standards; City of Ocala's centrifuge and rotary press installation at Water Reclamation Facilities (ITB WRS/260503 and ITB WRS/260536, bids due April 7 and April 8, 2026), where turnkey biosolids dewatering systems replace belt filter press and centrifuge equipment; and Maryland Environmental Service's Cox Creek Dredged Material Containment Facility capacity recovery (RFP 1265188, proposals due March 20, 2026), calling for removal and dewatering of 50,000 cubic yards of dredged material using anionic polymers and coagulants to pass paint-filter testing. M/WBE participation is encouraged or required across most solicitations; prevailing wage applies to federally funded projects and some state procurements.
