UNSPSC 31311106: Non metallic solvent welded pipe assemblies

UNSPSC 31311106 Non metallic solvent welded pipe assemblies, a Commodity code, covers plastic water and sewer piping systems—primarily HDPE, PVC, and specialty polymeric pipes—that state and local water authorities and public works departments procure for infrastructure replacement, system upgrades, and new construction. Recent solicitations show this code captures supply contracts for bulk pipe inventory, materials for waterline replacements, and integrated pipe-system projects that bundle piping with fittings, valves, and ancillary components. Issuing bodies span municipal water utilities, county water authorities, municipal public works departments, and regional water-sewer authorities across the Southeast and Southwest. The City of Phoenix Public Works Department, Orange County Florida, Gwinnett County Georgia, and the Beaufort-Jasper Water and Sewer Authority are among repeat or recent buyers. Solicitation types are predominantly IFB and sealed competitive bid formats, reflecting the commodity and infrastructure nature of the work. The City of Phoenix issued IFB 26-SW-0379 (due August 12, 2026) for a three-year as-needed supply contract covering HDPE pipe from 1.5 to 24 inches diameter and PVC pipe from 0.75 to 4 inches, requiring 24- to 48-hour delivery and local inventory maintenance. Gwinnett County Board of Commissioners solicited stormwater pipe including HDPE 12- to 24-inch diameter sections under ITB BL079-26 (due May 19, 2026) on an annual contract with four-year initial term and optional renewals. Orange County Florida's Y26-126 sewer pipes and fittings procurement (bid opening January 22, 2026, updated from an earlier deadline) carries an estimated five-year spending total of approximately $28.7 million and spans 56 line items of PVC and ductile iron systems.

Recent activity concentrates in Florida, Georgia, and South Carolina, with secondary activity in Arizona, Connecticut, Massachusetts, and California. Water main replacement projects dominate the pipeline-construction segment: Barnwell County South Carolina (CIP-2257 Heyward Street waterline, due August 4, 2026) encompasses 1,950 linear feet of eight-inch and four-inch water mains; Beaufort-Jasper Water and Sewer Authority (CIP-2411 Penn Center waterline, due May 27, 2026) specifies 1,950 linear feet of eight-inch and four-inch mains with jack-and-bore installation; Bryan County Georgia (PE77523NONST2026000000069 water main extension, due March 31, 2026) called for approximately 14,350 linear feet of 30-inch PVC water main with HDD and jack-and-bore operations. Sewer and stormwater projects layer in: Barnwell County (2026IFB030 Mason Street grinder station conversion, due July 7, 2026) specified 8-inch PVC collection main replacement with new 6-inch and 4-inch laterals; Palm Bay Florida (41ITB26 I-95 outfall pipe replacement, due July 14, 2026) involved outfall piping replacement under state environmental permits. Notla Water Authority Georgia (PE33821NONST2026000000002 water system improvements, due June 18, 2026) solicited approximately 2,400 linear feet of 6-inch water line under ARPA federal funding. Scope overlap between supply contracts and construction projects suggests active replacement cycles in municipal water systems across the target geographies, with federal stimulus and state revolving fund backing supporting large-scale infrastructure modernization through 2026 and into 2027.
