UNSPSC 25101609: Sludge or sewage handling trucks

UNSPSC 25101609 Sludge or sewage handling trucks, a Commodity code, represents specialized equipment for transporting and managing liquid waste from wastewater treatment facilities. State and local governments procure these vehicles to support routine maintenance, emergency response, and regulatory compliance at treatment plants, with recent solicitations emphasizing tanker configurations, vacuum and pumping systems, and closed-system construction to meet environmental standards. The buying mix spans state environmental agencies, county utilities, and municipal water districts, with repeat activity from Maryland Environmental Service and regional water authorities managing multiple treatment facilities. The work being solicited encompasses both purchase of new equipment and retrofitting of existing chassis with specialized hauling systems, though recent opportunities show greater concentration in contracted hauling services rather than vehicle procurement.

Geographic activity centers on Maryland, California, and Florida, with representative recent opportunities including Maryland Environmental Service's multiple liquid sludge hauling procurements (sealed bid solicitations posted May through August 2026 for transport of wastewater byproducts from treatment plants in Washington, Frederick, and Carroll Counties), Sacramento County Water Agency's RFB for a self-contained, skid-mounted valve exerciser equipped with hydro-excavation and vacuum systems (due October 30, 2026), and California State Parks' IFB for sewer tank and sand trap pumping services at San Onofre State Beach (due August 31, 2026). These solicitations typically specify closed tanker trucks, vacuum-capable equipment meeting state and federal environmental regulations (COMAR, 40 CFR Parts 257, 258, 503), per-gallon or unit-price compensation structures, and contractor responsibility for regulatory compliance and spill liability. The code shows steady regional demand but limited national concentration; activity remains episodic rather than continuous, with opportunities driven by facility maintenance cycles and multi-year contract renewals tied to wastewater operational budgets.
