UNSPSC 31311606: Non metallic sonic welded pipe assemblies

UNSPSC 31311606 Non metallic sonic welded pipe assemblies (Commodity) covers the supply of plastic and composite water, sewer, and drainage pipe systems that state and local governments procure for infrastructure replacement and new construction. The recent opportunities show state and local buyers sourcing High-Density Polyethylene (HDPE) pipe, Polyvinyl Chloride (PVC) pipe, and corrugated polypropylene pipe in diameters ranging from 0.75 inches to 60 inches, along with associated fittings, couplings, and specialty components such as elbows, tees, and conduit assemblies. Work spans water main replacement, sewer collection system upgrades, stormwater drainage rehabilitation, and airport utility distribution; the code captures both firm-fixed supply contracts and integrated design-build projects involving pipe system installation and long-term operation.

Issuing bodies include municipal utilities commissions (Town of Waterford, Connecticut), county utilities departments (DeKalb County, Georgia; Gwinnett County, Georgia; Barnwell County, South Carolina), city public works and water authorities (City of Phoenix, City of Arlington, City of Lavonia, Notla Water Authority), and special-purpose water and sewer authorities (Beaufort-Jasper Water & Sewer Authority, Solid Waste Authority of Palm Beach County). Recent activity concentrates in Georgia, South Carolina, Connecticut, Arizona, and Florida, with secondary opportunities in Kentucky and Texas.
