UNSPSC 71122716 Subsea maintenance service is a Commodity code representing well abandonment, plugging, and related subsurface remediation services that state and local governments purchase to decommission orphaned, end-of-life, and surplus wells across water utilities, oil and gas regulatory agencies, and environmental remediation programs. Recent state and local solicitations under this code focus heavily on plugging and site restoration of orphaned gas storage wells, municipal water well rehabilitation, exploratory and monitoring well construction, and associated drilling and pump services. The Michigan Department of Environment, Great Lakes, and Energy has issued four concurrent direct solicitations in July 2026 for plugging and site restoration of 38 orphan gas storage wells across Gratiot and Montcalm counties under prequalified vendor lists, each requiring unit pricing across 68 line items covering labor, equipment, materials, wireline services, waste disposal, and site restoration, with Davis-Bacon prevailing wage requirements and firm pricing for project duration. Issuing bodies conducting recent procurement under this code span state environmental and natural resources agencies (Michigan EGLE, Texas General Land Office, Railroad Commission of Texas, Illinois Department of Natural Resources, Mississippi Oil and Gas Board), county governments and special districts (Seminole County, Sarasota County, Collier County, Marion County in Florida; San Bernardino County in California; Gratiot and Montcalm counties in Michigan), and municipalities and water utilities (City of Lubbock, City of Watertown, City of Palm Bay, Eastern Municipal Water District in California). Repeat buyers include the Michigan Department of Environment, Great Lakes, and Energy and the Mississippi Oil and Gas Board, both actively managing portfolios of orphaned well abandonments funded through federal Infrastructure Investment and Jobs Act dollars.

Geographic concentration is heaviest in Michigan, Mississippi, Texas, and Florida, with secondary activity in California, Illinois, Georgia, and other states managing legacy oil and gas or municipal water infrastructure. The Michigan Department of Environment, Great Lakes, and Energy's Gratiot County orphan well portfolio represents the most recent and concentrated activity, with four separate solicitations posted in late June and early July 2026 for 38 total wells across New Haven Energy LLC facilities, all due July 21, 2026, at 3:00 p.m. Eastern, with mandatory pre-proposal meetings on July 9, 2026. The Mississippi Oil and Gas Board has issued three separate Invitations for Bids in March and April 2026 for plugging and reclamation of 17 orphaned oil and gas wells across multiple counties, funded through federal Infrastructure Investment and Jobs Act Formula grants with responses due in April 2026. Sarasota County, Florida issued a Request for Quotes in early July 2026 for single-well abandonment at a residential property (response deadline July 10, 2026, $50,000 ceiling) and a bid in June 2026 for exploratory and monitor well construction at the Dona Bay Surface Water Storage Facility (response deadline July 29, 2026). Hillsborough County, Florida solicited a two-year water well maintenance and repair contract estimated at $688,073 for 67 irrigation and potable wells across multiple parks (response deadline June 12, 2026). San Bernardino County Department of Public Works issued an RFQ in July 2026 for on-call well and pump maintenance and repair services across 32 water wells and 28 booster stations, with a maximum contract amount of $2.8 million over five years (September 2026 through June 2031). Eastern Municipal Water District in California issued an RFP in April 2026 for well maintenance and rehabilitation services with a minimum two-award structure and five-year contract term beginning July 2026. The code shows active, distributed procurement across multiple states and issuing bodies, with a notable concentration of federal-dollar-funded orphaned well work in oil and gas states and routine municipal water well maintenance work in water utilities nationwide.
