UNSPSC 71161405: Well site pit lining services

Services to design monitor and dispose of linings used in the pit area during drilling.

UNSPSC 71161405 Well site pit lining services is a Commodity code that appears in recent state and local solicitations primarily for landfill gas extraction system infrastructure and digester gas utilization projects, though the code's nominal scope does not align tightly with the work actually being procured. The Dalton-Whitfield Solid Waste Authority's ITB for landfill gas collection and control system expansion (posted April 17, 2026, due May 21, 2026) represents the most concrete recent opportunity tagged to this code and encompasses surveying, installation of gas extraction wells with HDPE casing, approximately 4,100 linear feet of perforated horizontal collectors, lateral and air supply piping, wellheads, condensate sumps, isolation valves, controls, monitoring equipment, and side slope seeding and erosion control work. The Eastern Municipal Water District's RFP for a Design-Build-Finance-Own-Operate-Maintain digester gas utilization project at three regional water reclamation facilities in Riverside County, California (posted February 24, 2026, due April 13, 2026) involves conversion of digester gas to renewable natural gas or other energy products, with the selected proposer bearing design, construction, financing, operations, and maintenance responsibilities over a 15- to 20-year term. Both opportunities require substantial contractor experience in similar projects and compliance with applicable air quality and permitting regulations. A third opportunity, the City of DeBary's irrigation system upgrade for Rob Sullivan Park (posted April 13, 2026), involves Hunter controller and piping installation and shows minimal relevance to the well site pit lining code classification.

The issuing-body mix includes special-purpose solid waste and water authorities in Georgia and California, supplemented by a city government (DeBary, Florida), indicating activity concentrated in the Southeast and West rather than nationally distributed. The Dalton-Whitfield Solid Waste Authority's procurement requires Georgia-licensed general contractors with a minimum five years' experience in landfill gas collection systems and completion of at least five similar or larger projects within the past five years, with mandatory pre-proposal conference on May 1, 2026, and liquidated damages up to $5,000 per day for delays beyond final completion. The Eastern Municipal Water District's RFP mandates five years of direct DBFOOM digester gas experience, audited financial statements, and estimated bid, payment, and performance bonds of $20 million, $2 million, and $2 million respectively, with a mandatory pre-proposal meeting on March 9, 2026, mandatory site tours March 18–19, 2026, and interviews anticipated May–June 2026. Neither the Solid Waste Authority nor the Water District imposed set-aside designations for disadvantaged enterprises or minority-owned businesses. Recent activity under this code is sparse and concentrated in specialized infrastructure projects for municipal waste and water treatment facilities.
