UNSPSC 71112031: Well tubular services

Includes repair of tubular services.

UNSPSC 71112031 Well tubular services is a Commodity code. State and local governments procure under this code materials and installation labor for subsurface well construction and casing systems, particularly for landfill gas extraction wells. The Dalton-Whitfield Solid Waste Authority's April 2026 ITB for its Old Dixie Highway Municipal Solid Waste Landfill demonstrates the scope: surveying of gas extraction well locations, installation of landfill gas extraction wells with HDPE casing, approximately 4,100 linear feet of perforated horizontal collectors, 7,420 linear feet of lateral piping in multiple diameters, liquefied fossil gas wellheads, condensate sumps, isolation valves, and controls. Issuing bodies under this code include solid waste authorities and regional water reclamation districts. Georgia-licensed general contractors with a minimum of five years' experience in landfill gas collection and control system construction and a track record of at least five similar or larger projects within the past five years compete for these contracts. On-site labor requirements typically mandate a minimum of 50 percent of work performed directly by the contractor's forces.

Recent activity concentrates in Georgia and California. The Dalton-Whitfield Solid Waste Authority's Landfill Gas Collection and Control System expansion (ITB PE75552NONST2026000000061, due May 21, 2026) represents a single large project with a 120-calendar-day Substantial Completion deadline and liquidated damages of $2,000 per day for the first 90 days following Substantial Completion and $5,000 per day thereafter. The Eastern Municipal Water District's Digester Gas Utilization Project (RFP 3900, due April 14, 2026) in Riverside County, California involves a Design-Build-Finance-Own-Operate-Maintain agreement to convert digester gas from three Regional Water Reclamation Facilities into renewable natural gas or other marketable energy products, with a contract term of 15 or 20 years plus optional extensions and substantial completion with facility commissioning targeted for June 2029. The UNSPSC code also captures portions of the EMWD's work scope involving subsurface gas extraction and transfer piping infrastructure, though the full procurement spans multiple commodity families. No other recent opportunities in the source material align with the well tubular services code scope.
