UNSPSC 23201004: Wetted wall column

UNSPSC 23201004 Wetted wall column is a Commodity code that encompasses specialized flow measurement and water metering equipment used by state and local water utilities. Recent procurement activity under this code reflects purchasing of precision ultrasonic flow meters and master water meters designed for potable and reclaimed water systems, rather than traditional wetted-wall column apparatus. State and local water utilities — municipal water departments and regional public utilities districts — are the primary issuing bodies, with activity concentrated among water reclamation and utility management functions. The work involves specification and procurement of factory-built, standards-compliant metering equipment with exact technical configurations, delivery to operational facilities, and compliance with American Water Works Association (AWWA) and industry standards.

Recent activity appears concentrated in Florida, where the City of St. Petersburg issued a quote solicitation (QUOTE26188) on August 13, 2026, for five Panametrics AT600 Ultrasonic FlowMeters with a response deadline of April 3, 2026, and an estimated procurement value in the range of $35,772 to $40,000 including freight and delivery; and Collier County Public Utilities Department issued a Notice of Intent to Single Source Master Meter Octave Series Water Meters (PUR18037) on June 12, 2026, for a contract term running October 1, 2026 through September 30, 2029. Both solicitations target reclaimed and non-potable water metering applications. The St. Petersburg solicitation is a competitive quote process open to vendors with two-plus years of flow meter experience and compliance with Florida registration and E-Verify requirements; Collier County's procurement is a sole-source designation requiring responses only to contest the single-source determination. Insurance and small-business participation encouragement appear in the competitive solicitation but are not binding prerequisites.
