UNSPSC 71141100: Well plugging and abandonment services

Services to prepare a well to be closed permanently.

UNSPSC 71141100 Well plugging and abandonment services is a Class code covering groundwater well installation, maintenance, repair, and gas extraction infrastructure — work driven by municipal water systems, solid waste authorities, and state environmental agencies managing subsurface infrastructure. State and local governments are soliciting under this code for irrigation well drilling and construction, landfill gas collection system installation, oil and gas well maintenance addressing methane leaks, and digester gas utilization projects converting biosolids-treatment byproducts into renewable energy. Issuing bodies include county public works departments (Orange County, California), solid waste authorities (Dalton-Whitfield, Georgia), municipal water districts (Eastern Municipal Water District, Riverside County, California), state conservation agencies (California Department of Conservation), and city engineering departments (DeBary, Florida). Work typically requires state-licensed general or drilling contractors with specialized experience in well construction, gas extraction systems, or both; prevailing wage compliance and comprehensive bonding (bid security ranging from 5–10 percent, performance and payment bonds at 100 percent of contract value) are standard.

Recent activity concentrates in California and Georgia, with additional solicitations in Florida. Orange County Public Works posted an IFB on April 22, 2026, for the Mile Square Regional Park Phase 1 Groundwater Well Project (estimated $1,827,631, response due January 4, 2024), restricted to five pre-qualified contractors, calling for conductor borehole installation, pilot drilling, casing, mechanical development, and pumping tests at a depth of 300 feet with 800 gallons-per-minute capacity. The Dalton-Whitfield Solid Waste Authority issued an ITB on April 17, 2026, for a landfill gas collection and control system expansion (response due May 21, 2026), requiring surveying, well installation with HDPE casing, approximately 4,100 linear feet of perforated collectors, condensate management, and slope seeding; Georgia-licensed general contractors must demonstrate five years' experience and completion of five similar projects in the past five years. The California State Department of Conservation posted an indefinite-quantity IFB on March 20, 2026 (due April 3, 2026), for well maintenance and removal of associated facilities addressing methane leaks from oil and gas operations on an as-needed basis. The Eastern Municipal Water District (Riverside County) issued an RFP on February 24, 2026 (due April 13, 2026), for a 15–20 year Design-Build-Finance-Own-Operate-Maintain agreement to develop digester gas utilization facilities at three regional water reclamation facilities, converting 50–61% methane digester gas into renewable natural gas or other marketable products, with technical proposals scored to 70 points and cost to 30 points, and contract execution anticipated October 2026 with substantial completion by June 2029.
