UNSPSC 76121700: Liquid waste treatment

UNSPSC 76121700 Liquid waste treatment is a Class code covering chemical treatment, chemical supply, removal, and disposal services for wastewater and water treatment operations. State and local governments procure under this code a mix of consumable treatment chemicals (sodium bisulfite, silicon dioxide defoamer, liquid polymer, chlorine dioxide), specialty equipment and parts (membrane diffusers, polymer blending units, SCADA and PLC systems), labor-intensive services (septic tank inspection and pumping, bypass pumping, centrifuge parts and repair), and capital projects including facility rehabilitation and sludge disposal. Recent opportunities show active procurement across municipal water pollution control facilities, wastewater treatment plants, water reclamation facilities, and regional treatment complexes.

The issuing bodies span cities (Phoenix, Atlanta, Meriden, Bradenton, Waxahachie, Shelton, Salem, Santa Cruz, Calhoun, Cairo, Flowery Branch), counties (Collier, Beaufort, Gwinnett, Pasco, Orange, Pinal, DeKalb, Athens-Clarke, Clackamas, Clayton, Seminole, Hillsborough), state agencies (Oregon, California Department of Fish and Wildlife, Maryland Environmental Service, Florida), transit or special-purpose districts (Eastern Municipal Water District, Tampa Convention Center), and regional authorities.
