UNSPSC 31311306: Non metallic bolted pipe assemblies

UNSPSC 31311306 Non metallic bolted pipe assemblies (Commodity) covers the supply of plastic, composite, and metal-coated pipe systems and fittings that state and local water, wastewater, and stormwater utilities procure for infrastructure repair, replacement, and new construction. Recent activity shows state and local governments buying PVC sewer pipe, HDPE and PVC water distribution pipe, corrugated polypropylene drainage pipe, and associated fittings (couplings, elbows, tees, bends) on firm-fixed pricing, typically as multi-year requirements contracts with as-needed delivery or as project-specific installations embedded in larger civil works bids. The issuing bodies span city water utilities (Phoenix, Arlington, Grovetown, Cairo, Lavonia), county water and wastewater authorities (DeKalb County, Beaufort-Jasper Water & Sewer Authority, Gwinnett County), town utility commissions (Waterford, Connecticut), state departments (Kentucky Transportation Cabinet for drainage pipe), and special-purpose authorities (Notla Water Authority, Palm Beach Solid Waste Authority). Water distribution and stormwater pipe products dominate the procurement mix, with suppliers required to meet ANSI/AWWA standards for potable water applications and state-specific material specifications.

Geographic activity concentrates in the Southeast and Southwest, particularly Georgia (multiple city and county utilities), Connecticut (Waterford town utility), Florida (Palm Bay, Palm Beach County), and South Carolina (Beaufort-Jasper, Barnwell County), with additional federal-funded procurements in Kentucky. Recent representative opportunities include DeKalb County's October 7, 2026 ITB for PVC sewer pipes, fittings, and couplings under a three-year multiyear contract for wastewater and storm drainage maintenance; the City of Phoenix's September 30, 2026 IFB for industrial pipe and fittings (HDPE 1.5" to 24", PVC 0.75" to 4") on a three-year term with delivery within 24–48 hours and DBE participation requirements; the City of Arlington's May 21, 2026 contract for HDPE water pipe (PE4710, ANSI/AWWA C906) in five diameter and design-rating specifications; and the Kentucky Transportation Cabinet's October 2, 2026 federally funded RFB for corrugated polypropylene pipe (12"–60" diameter) subject to Buy America/BABA manufacturing compliance. Waterline replacement work is also being solicited as prime construction contracts (Barnwell County, Grovetown, Waterford utility commission) where pipe assemblies are embedded in broader installation scopes with multiple deliverables; in these cases, the UNSPSC code may flag the material component rather than the full construction service. Many utilities require local inventory, 24–48 hour delivery windows, firm pricing for multi-year terms, and compliance with regional set-asides (Connecticut DAS small and minority-owned business 25% set-aside, Georgia DBE participation goals, Phoenix DBE-N program). Bidders should monitor ongoing Georgia county utilities (Gwinnett, DeKalb, Augusta, Grovetown, Cairo) and South Carolina water authorities for recurring multi-year pipe supply agreements.
