UNSPSC 71161109: Well stimulation services

Evaluation, design or testing of services for treatment performed to restore or enhance the productivity of a well.

UNSPSC 71161109 Well stimulation services is a Commodity code that in recent state and local procurement activity encompasses landfill gas extraction system design, installation, and operation — including well drilling, lateral piping networks, condensate management infrastructure, and long-term energy conversion projects that extract and beneficially use gases from solid waste and wastewater treatment facilities. The code sees activity from special-purpose districts and local authorities managing waste and water infrastructure, with work ranging from capital construction of new extraction systems to long-term design-build-finance-operate contracts for gas-to-energy conversion. Recent solicitations show Georgia waste authorities and California water districts issuing competitive bids and RFPs for projects that integrate gas capture with renewable energy production or off-gas management, requiring contractors with specific multi-year experience in landfill gas and digester gas system construction and operation.

Recent opportunities cluster in Georgia and California. The Dalton-Whitfield Solid Waste Authority issued an ITB (PE75552NONST2026000000061) on April 17, 2026, for construction and installation of a landfill gas collection and control system expansion at its Old Dixie Highway Municipal Solid Waste Landfill in Dalton, Georgia, with bids due May 21, 2026, requiring Georgia-licensed General Contractors with minimum five years' landfill gas system experience and at least five completed similar projects. The Eastern Municipal Water District in Riverside County, California, released an RFP (3900) on February 24, 2026, for a 15- or 20-year Design-Build-Finance-Own-Operate-Maintain agreement to convert digester gas at three Regional Water Reclamation Facilities into renewable natural gas or marketable energy products, with proposals due April 13, 2026, at 4 p.m. Pacific Time; this project carries estimated bonding of $20 million, $2 million, and $2 million and requires proposers to demonstrate minimum five years of direct DBFOOM digester gas experience and audited financials for the past three years. Both opportunities enforce compliance with state regulatory regimes (Georgia Security and Immigration Compliance Act for the Dalton project; California Department of Industrial Relations prevailing wage and South Coast Air Quality Management District rules for the EMWD project) and neither designates set-asides for disadvantaged enterprises.
