UNSPSC 73152001: Liquid filling services

UNSPSC 73152001 Liquid filling services, a Commodity code, encompasses the supply and factory assembly of specialized water treatment equipment — specifically flow controllers, butterfly valves, and related instrumentation designed to regulate and measure potable water flow through municipal water systems. State and local water utilities, particularly municipal water departments and treatment authorities, issue solicitations under this code for replacement and upgrade of flow measurement and control apparatus at potable water treatment plants. The work involves vendor-supplied equipment that meets industry standards (AWWA C504 compliance, ASTM material specifications, NSF 61 approval for potable water contact) and includes factory testing to specified accuracy tolerances, delivery in assembled or pre-assembled form, and supply of operation and maintenance documentation. Vendors typically provide equipment only, with the municipality responsible for installation and integration with existing infrastructure.

Recent activity centers on Texas municipal water systems. The City of Lubbock, Texas, issued Invitation to Bid (ITB) 26-19653-YB in May 2026 for a 16-inch rate of flow controller and butterfly valve assembly for the North Water Treatment Plant, with bids due May 27, 2026, at 3:00 p.m. The specification required a venturi-type flow controller with 0–144 inches water column range, AWWA C504-compliant butterfly valve with cast iron body and Type 316 stainless steel throat liner, and factory assembly and testing to within 0.5 percent flow rate accuracy. The City offered a local vendor preference of five percent for bidders with principal place of business within city limits on contracts under five hundred thousand dollars and extended cooperative purchasing authority to Frenship Independent School District, Lubbock County, Lubbock Independent School District, and Texas Tech University. No specific budget or award value was published. A non-mandatory site visit was scheduled for May 20, 2026, at the treatment plant, with RSVP required by May 19, 2026.
