UNSPSC 71131405: Flow line hydrate formation control services

Control formation of hydrates in production flowlines and equipment

UNSPSC 71131405 Flow line hydrate formation control services is a Commodity code that captures water infrastructure rehabilitation and replacement work—specifically trenchless pipe lining, water main replacement, and sewer/stormwater system cleaning and inspection services—as state and local water utilities, municipalities, and special districts modernize aging distribution networks and treatment facilities. The code shows activity across municipal water and wastewater departments, county utility commissions, and city public works agencies, with issuers ranging from small towns to mid-sized cities. Recent solicitations include the City of Alpharetta's RFP 26-115 for on-call trenchless pipe lining (cured-in-place pipe and spincast methods) for stormwater pipes 12 to 120 inches in diameter, posted April 30, 2026 with proposals due May 28, 2026; the City of Atlanta Department of Watershed Management's IFB for color video pipeline inspection systems and sewer cleaning equipment, due June 23, 2026; and the Town of Waterford Utility Commission's IFB 26-007 for plastic-to-copper water service line replacement on paving program roads, due May 21, 2026.

Activity concentrates in the Southeast and South—Georgia (Jones County, City of Atlanta, Paulding County, City of Albany), Florida (City of DeBary, Orange County), Connecticut (Town of Waterford), and Texas (City of Lubbock, City of Fort Worth, Texas Water Development Board)—with secondary solicitations for water treatment plant design services and program management. The geographic spread reflects ongoing investment in aging water infrastructure across suburban and rural systems. The mix of recent opportunities spans routine replacement work (copper service lines in Connecticut, water mains in Georgia), specialized equipment and services (vacuum truck and jet rodding for Phoenix; video pipeline inspection systems for Atlanta), and design-phase procurements (qualifications-based selections for treatment plant upgrades in Lubbock). Most opportunities are competitively bid IFBs or RFPs with firm timelines; Connecticut contracts carry 25 percent subcontractor set-asides for DAS-certified small and minority-owned businesses, while Phoenix work requires DBE-N compliance. No recent opportunities show this code tagged to projects outside water or wastewater scope—the alignment between code name and actual solicitation activity is consistent.
