UNSPSC 71122306: Subsea well equipment maintenance services

Maintenance and repair of subsea well equipment.

UNSPSC 71122306 Subsea well equipment maintenance services is a Commodity-tier code that encompasses plugging, remediation, and reclamation of orphaned and abandoned oil and gas wells, as well as maintenance and repair of municipal water supply wells and associated infrastructure. State and local governments buying under this code procure drilling services, well abandonment and plugging operations, pump and motor replacement, well rehabilitation, equipment removal, site restoration, and emergency response services for both onshore wells and groundwater systems. The code also captures design and engineering services for well improvements, monitoring well construction, and hydrogeological consulting.

The recent activity shows substantial work across state environmental agencies, county water utilities, municipalities, and regional water districts. The Michigan Department of Environment, Great Lakes, and Energy dominates the current activity, with four separate direct solicitations posted in mid-July 2026 (all due July 21, 2026) for orphan gas storage well plugging and site restoration across Gratiot and Montcalm counties—spanning 38 total wells under prequalified contractor lists and Davis-Bacon prevailing wage requirements. Additional representative opportunities include Hillsborough County Board of County Commissioners (Florida) issuing an ITB for water well maintenance and repair services estimated at $688,073 over two years (June 2026), the Eastern Municipal Water District in California issuing an RFP for on-call well maintenance with a maximum contract value of $2.8 million over five years (July 2026), and the Mississippi Oil and Gas Board conducting multiple IFBs for orphan well plugging under Infrastructure Investment and Jobs Act funding (March–May 2026). Geographic concentration is heaviest in Michigan (orphan well remediation), California (water utility wells), Mississippi (oil and gas well abandonment), Florida (municipal water wells and wastewater pump stations), and Texas (well services). The code shows sustained activity across Midwestern, Southern, and Western states, with federal infrastructure grant funding increasingly driving orphan well plugging procurement at state and regional levels.
