UNSPSC 76121700: Liquid waste treatment

UNSPSC 76121700 Liquid waste treatment is a Class code covering the removal, treatment, and disposal of liquid waste streams from municipal water and wastewater systems. State and local governments procure under this code a mix of chemical treatment services, biosolids and sludge handling, equipment replacement for treatment processes, facility upgrades, and specialized labor for operations and maintenance at water reclamation and treatment plants. Recent solicitations span chemical supply contracts for polymer and supplemental carbon products; sludge removal and land application; membrane diffuser replacement; aeration basin and process control upgrades; SCADA and instrumentation work; and on-call repair services at pump stations and treatment facilities.

The issuing body mix is broad and includes regional water authorities, county utilities departments, municipal water and sewer divisions, city departments of public works, and special-purpose authorities managing reclamation and resource recovery. Water and wastewater utilities in Florida, Arizona, Georgia, Texas, California, Massachusetts, New Jersey, Oregon, and Maryland have posted activity in the past sixty days.
