UNSPSC 71131309: Well profile modification services

Services to stimulate a well to change the profile.

UNSPSC 71131309 Well profile modification services is a Commodity code that spans landfill gas extraction well installation, digester gas system development, and related subsurface infrastructure modification work being solicited by special-purpose districts and municipal authorities. Recent state and local solicitations under this code reflect capital projects to expand or establish gas collection and utilization systems at solid waste and wastewater treatment facilities. The Dalton-Whitfield Solid Waste Authority's ITB for landfill gas collection and control system expansion (PE75552NONST2026000000061, due May 21, 2026) exemplifies the scope: surveying and installation of landfill gas extraction wells with HDPE casing, perforated horizontal collectors, lateral and conveyance piping, wellheads, condensate sumps, and associated controls and monitoring equipment, requiring Georgia-licensed general contractors with minimum five years' experience in landfill gas system construction and successful completion of at least five similar projects. Similarly, the Eastern Municipal Water District's RFP 3900 for a Digester Gas Utilization Project (due April 14, 2026) seeks a Design-Build-Finance-Own-Operate-Maintain partner to convert digester gas at three regional water reclamation facilities into renewable natural gas or energy products across a 15- or 20-year term, requiring proposers with minimum five years of direct DBFOOM digester gas experience and substantial bonding capacity. Issuing bodies include special-purpose solid waste authorities and regional water districts rather than general municipal procurement offices or state departments.

Geographic activity concentrates in Georgia and California based on the recent opportunities. The Dalton-Whitfield Solid Waste Authority project is in Georgia; the Eastern Municipal Water District Digester Gas Utilization Project spans three facilities in Riverside County, California. The code shows limited recent activity overall—only two core gas system opportunities appear in the recent block, alongside unrelated records (a city manager executive search and an irrigation system retrofit that do not align with the code's profile modification scope). Contractors pursuing work here face substantial qualification thresholds: specialized experience in landfill or digester gas infrastructure, performance bonding in the millions, and multi-year project delivery timelines with significant liquidated damages (the Dalton-Whitfield project assesses $2,000–$5,000 per day). Pre-bid and pre-proposal conferences are mandatory, and compliance with state environmental and labor regulations is required. The market for this commodity appears narrow and specialized, concentrated among regional water and solid waste authorities undertaking renewable energy and gas management capital projects.
