UNSPSC 71122700: Well maintenance services

Maintenance, repair and failure analysis performed on the well or equipment on the well which make include refurbishments, repair or modifications.

UNSPSC 71122700 Well maintenance services is a Class code that spans the full range of inspection, repair, rehabilitation, cleaning, plugging, and abandonment work state and local governments purchase for water supply wells, irrigation systems, monitoring wells, and orphan or abandoned oil and gas wells. Recent solicitations show state and local buyers purchasing well video surveys and casing repair, well cleaning and redevelopment, monitoring well installation and exploratory drilling, deep well and pump station construction, stock water well drilling and infrastructure, on-call emergency maintenance contracts, and comprehensive orphan well plugging and site restoration under federally funded programs.

Issuing bodies span state water and environmental agencies (Michigan Department of Environment, Great Lakes and Energy, Mississippi Oil and Gas Board, Illinois Department of Corrections, California Department of Water Resources), county utilities and public works departments (Seminole County, Sarasota County, Escambia County, Gwinnett County, San Bernardino County), municipalities (City of Bend, City of Reynolds, City of Wrens, City of Albany, City of Austin, Town of Ayer, Town of Fairhaven), water districts (Hilldale Water District, Boulder County Parks and Open Space), state parks departments (Oregon Parks and Recreation Department, Texas Parks and Wildlife Department), and single-purpose districts. Michigan EGLE emerges as a major repeat buyer, issuing multiple prequalification and direct solicitations for orphan well plugging across the Lower Peninsula. Recent activity clusters heavily in Florida, Michigan, Mississippi, Georgia, Illinois, Massachusetts, and Oregon, with additional work in Texas, Arizona, California, and Colorado. Representative recent solicitations include the Town of Ayer, Massachusetts RFQ for well cleaning and redevelopment at two municipal wells (quotes due November 13, 2026); the City of Albany, Georgia sealed bid for Well No. 21 rehabilitation (bids due November 16, 2026); the Mississippi Oil and Gas Board IFB for plugging, remediation, and reclamation of nine orphaned oil and gas wells in Jasper and Jones Counties (bids due December 18, 2026); and Michigan EGLE's prequalification RFP for oil and gas well plugging services statewide (proposals due September 22, 2026, with five awardees receiving contracts totaling $800,000 over one year and five months). Orphan well plugging work funded under the Infrastructure Investment and Jobs Act and subject to Davis-Bacon prevailing wage requirements dominates the current pipeline, particularly in Michigan and Mississippi, where state environmental agencies are aggressively addressing legacy wells through federal grant funding.
