UNSPSC 31311606: Non metallic sonic welded pipe assemblies

UNSPSC 31311606 Non metallic sonic welded pipe assemblies is a Commodity code that spans plastic water and sewer infrastructure procurement across state and local water utilities, municipalities, and special-purpose water authorities. State and local governments buy under this code primarily High-Density Polyethylene (HDPE) water pipe, PVC sewer and water pipe, reinforced concrete pipe (RCP), corrugated metal pipe, and associated fittings—elbows, couplings, isolation valves, fire hydrants, and service line components—supplied both as direct material purchases and as integrated elements within water main replacement, booster station construction, and water/sewer system upgrade projects. Recent solicitations show mixed scope: some are stand-alone supply contracts for pipe inventory (City of Arlington Water Utilities' annual HDPE water pipe requirements contract; Gwinnett County's stormwater pipe purchase agreement), while others embed pipe procurement within full-scale infrastructure work (Barnwell County waterline replacement, Bryan County water main extension and booster pump station, City of Lavonia water treatment plant upgrades). The issuing-body mix includes municipal water utilities (Arlington, Phoenix, Palm Bay), county water authorities (Beaufort-Jasper Water & Sewer Authority, Gwinnett County, Bryan County, Barnwell County), city public works departments (Phoenix, Swainsboro, Hogansville, Cairo), and special-purpose districts (Notla Water Authority in Georgia, Solid Waste Authority of Palm Beach County for landfill closure drainage). Repeat buyers in the dataset include Barnwell County (two waterline/sewer projects), Bryan County (booster station and water main), and several Florida municipalities.

Geographic activity concentrates in Georgia, Florida, South Carolina, and other Southeastern states, with notable recent solicitations in Arizona (Phoenix), Texas (Arlington), Connecticut (Waterford), California (Santa Clara County), and Massachusetts (Berkshire Regional Group Purchasing Program). Representative recent opportunities include the City of Phoenix Public Works Department's IFB 26-SW-0379 for HDPE and PVC pipe, fittings, and supplies on an as-needed three-year contract with two one-year extensions, due August 12, 2026, requiring 24- to 48-hour delivery and DBE-N compliance; Barnwell County's CIP-2257 Heyward Street Waterline Replacement IFB (2027IFB001), due August 4, 2026, calling for approximately 1,950 linear feet of eight-inch and four-inch water mains with isolation valves and fire hydrants; Bryan County's PE77523NONST2026000000069 water main extension project (March 31, 2026 deadline) for approximately 14,350 linear feet of 30-inch water main along Interstate 16; and the City of Arlington Water Utilities' annual requirements contract (260226) for HDPE pipe in multiple diameters and flow ratings, due May 21, 2026. Build America, Buy America Act compliance, prevailing wage standards under Davis-Bacon, and Section 3 HUD preference designations appear in federally or state-funded projects; SBE, MBE, and WBE participation goals are common. Delivery-speed expectations are aggressive—Phoenix requires 24- to 48-hour turnaround, Orange County's sewer pipes IFB calls for two-calendar-day standard delivery and four-hour emergency service, and Gwinnett County specifies fourteen-day delivery from order placement. Material standards frequently cite AWWA, ASTM, PE4710, and state DOT specifications, with F.O.B. destination pricing and firm quotes typical across multi-year contracts.
