UNSPSC 71141002: Well capping services

To regain control of a blowout well by installing and closing a valve on the wellhead.

UNSPSC 71141002 Well capping services is a Commodity code that state and local governments use to procure landfill gas extraction system infrastructure, including well installation, capping equipment, collection piping, and related control systems. The code shows activity from solid waste authorities and environmental utilities undertaking landfill gas remediation and energy recovery projects. Issuing bodies include dedicated solid waste authorities (such as the Dalton-Whitfield Solid Waste Authority in Georgia) and regional water reclamation districts that manage digester gas utilization from wastewater treatment. The work typically involves designing and installing gas extraction wells with HDPE casing, perforated horizontal collectors, laterals, wellheads, condensate management, monitoring equipment, and compliance with air quality regulations; contractors must demonstrate five or more years of direct experience in similar gas collection systems and maintain Georgia licensing or equivalent state registration where applicable.

Recent activity concentrates in the Southeast and California. The Dalton-Whitfield Solid Waste Authority issued an ITB on April 17, 2026, for a landfill gas collection and control system expansion at its Old Dixie Highway Municipal Solid Waste Landfill in Dalton, Georgia (solicitation PE75552NONST2026000000061), due May 21, 2026, calling for Georgia-licensed general contractors with five years' minimum experience and 50 percent on-site labor commitment, with a 120-day substantial completion deadline and liquidated damages of $2,000 to $5,000 per day. The Eastern Municipal Water District in Riverside County, California issued an RFP on February 24, 2026, for a Design-Build-Finance-Own-Operate-Maintain digester gas utilization project at three regional reclamation facilities (solicitation 3900), due April 13, 2026, structured as a long-term agreement (15 to 20 years) with bond requirements estimated at $20 million and revenue sharing tied to renewable natural gas sales, mandatory pre-proposal meeting March 9, 2026, and site tours March 18–19, 2026. Neither opportunity specifies set-aside designations for disadvantaged or minority-owned enterprises.
