UNSPSC 40141763: Water hammer arrester

A type of device that is installed to prevent high noise and vibration due to the impact wave generated by the fluid inside the pipeline that moves the fluid.

UNSPSC 40141763 Water hammer arrester is a Commodity code that encompasses pipe and fitting supply across water and wastewater infrastructure maintenance; state and local governments procure water hammer arresters as part of broader industrial pipe and fitting inventories rather than as standalone products. The solicitations tagged to this code reveal that purchasing agents are actually buying comprehensive pipe, fitting, valve, and related appurtenance packages to support ongoing water system maintenance and emergency repairs. The issuing bodies include city public works departments (Phoenix), county water and sewer authorities (Douglasville-Douglas County), county sanitation districts (Santa Clara County), and municipal utilities (Calhoun, Lavonia, Palm Bay). The scope of actual work spans HDPE and PVC pipe in multiple diameters, mechanical joint fittings, gate valves, tapping sleeves, quick-insert valves, resilient wedge insert valves, fire hydrants, curb stops, meter setters, and accessory kits—with water hammer arresters appearing as line items within larger material take-offs for water main relocation, sewer infrastructure rehabilitation, and as-needed inventory supply contracts.

Recent activity concentrates in Georgia, Florida, Arizona, and California. Representative opportunities include the City of Phoenix Public Works Department issuing IFB 27-SW-0447 (due September 30, 2026) for a three-year as-needed supply of industrial pipe, HDPE/PVC fittings, and equipment to support Phoenix Sky Harbor International Airport and other aviation facilities, with 24–48-hour delivery and local inventory maintenance required; the City of Augusta, Georgia soliciting ITB 27-116 (due September 29, 2026) for HDPE pipe, couplings, and end sections for down-drain installation with a Minority and Women Owned Business Enterprise Program requirement and local-bidder preference for projects under $100,000; and the Douglasville-Douglas County Water and Sewer Authority requesting sealed bids under IFB 327 (due October 7, 2026) for annual pipe fittings, concrete materials, valves, manhole products, and sewer couplings on an as-needed basis. Santa Clara County's Sanitation District No. 2-3 issued ITB on the Structural Defect Repair Project Phase 2 (due September 17, 2026) encompassing 1,080 linear feet of 6-inch HDPE pipe for sewer main replacement using pipe-burst technology alongside PVC and service-line wye fittings.
