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 encompasses the removal, plugging, abandonment, and site restoration of orphaned or decommissioned wells, along with routine maintenance and repair of active production and municipal water wells. State and local governments procure these services across water utilities managing groundwater assets, environmental cleanup agencies addressing orphaned oil and gas wells, counties and municipalities maintaining water supply infrastructure, and special-purpose districts operating irrigation and potable water systems. Recent activity shows substantial investment in orphan well remediation programs funded through federal infrastructure grants, alongside routine municipal well rehabilitation and emergency repairs.

The Michigan Department of Environment, Great Lakes, and Energy dominates recent activity, posting four simultaneous direct solicitations in July 2026 for plugging and site restoration of 38 orphaned gas storage wells across Gratiot and Montcalm counties (totaling $21 million estimated scope based on scale), with proposals due July 21, 2026, and attendance at mandatory pre-bid meetings on July 9, 2026, required at the New Haven Compressor Station. Bidders must be prequalified through prior RFP processes and submit detailed 68-line-item pricing matrices covering labor (including Davis-Bacon wage classifications), equipment rental (pole rigs, derrick rigs, wireline services), materials, and site restoration. Beyond Michigan, recent solicitations span water well maintenance contracts in California (San Bernardino County, Eastern Municipal Water District), Florida (Seminole County wastewater pump stations, Sarasota County well abandonment, Marion County production wells, Collier County, Hillsborough County), Illinois (Union County SFWA well and pump), Mississippi (seven orphaned well plugging projects through the Oil and Gas Board), Massachusetts (Fairhaven well cleaning, Greenfield well rehabilitation), and Texas (Railroad Commission statewide well plugging RFQ). Geographic concentration is strongest in the Sun Belt and Great Lakes states with active oil and gas legacies or large municipal water systems; federal orphan well remediation funding under the Infrastructure Investment and Jobs Act is driving sustained activity across traditionally oil-and-gas-producing states (Texas, Oklahoma, Mississippi) as well as areas with decommissioned wells.
