UNSPSC 23201004: Wetted wall column

UNSPSC 23201004 Wetted wall column (Commodity) represents water measurement and treatment equipment that state and local water utilities procure to monitor and control reclaimed and potable water flow and consumption. Recent state and local solicitations show purchasing spanning ultrasonic flow meters, particle counters for filter plants, water meters for reclaimed water service, and fire hydrant backflow prevention devices—a broader equipment category than the nominal code name suggests. Water utilities departments and water resources divisions are the primary issuing bodies, typically within county and municipal governments, with water system capital and maintenance activities driving procurement frequency and scale.

Geographic activity concentrates in Florida and Georgia, with recent opportunities from Collier County Public Utilities Department (Master Meter Octave Series water meters, sole-source procurement PUR18037, notice of intent posted June 12, 2026, response deadline June 12, 2026); City of St. Petersburg (five Panametrics AT600 Ultrasonic FlowMeters for the Southwest Water Reclamation Facility, RFQ QUOTE26188, posted April 16, 2026 with response due April 3, 2026, estimated value $35,772 to $40,000); Gwinnett County Board of Commissioners in Georgia (13 Chemtrac PC3400 particle counters at Lanier Filter Plant plus 6 units at Shoal Creek Filter Plant, sealed bid BL046-26, due May 8, 2026 with mandatory pre-bid April 16, 2026); and City of Dallas (three-year ID/IQ master agreement for fire hydrant backflow preventers, RFB BC2600029678, due March 27, 2026). Suppliers bidding this code compete on equipment specifications, delivery timelines, compliance with AWWA and NSF standards, insurance requirements, and maintenance documentation—with award often to the lowest responsive and responsible bidder.
