UNSPSC 73151709, Gas treatment service excluding chemical supply, is a Commodity code. State and local governments use this code to classify well and water system maintenance, repair, and abandonment services—including well video surveys, casing repair, pump maintenance, and orphan well plugging and site restoration. The code encompasses a mix of issuing bodies: state departments of environment and natural resources, county utilities and public works departments, municipal water and parks authorities, state parks systems, and special-purpose water and wastewater districts. Work solicited under the code ranges from routine maintenance contracts covering multiple wells across a jurisdiction to single-project plugging, rehabilitation, or abandonment at specific sites.

Recent activity shows heavy concentration in orphan well plugging across Michigan, Mississippi, and Florida, funded through the Infrastructure Investment and Jobs Act. Michigan's Department of Environment, Great Lakes, and Energy has posted the most volume: prequalification RFPs (e.g., RFP7612600000025221, due September 22, 2026) for oil and gas well plugging, drilling, and site restoration services statewide, followed by multiple direct solicitations for specific well clusters in Gratiot, Montcalm, and Kent Counties (DS7612600000000321 through DS7612600000000352, July proposals due July 21, 2026, all restricted to prequalified vendors and subject to Davis-Bacon prevailing wage requirements). The Mississippi Oil and Gas Board has issued IFB 3160008162 for plugging of nine orphaned wells in Jasper and Jones Counties (bids due December 18, 2026, mandatory pre-bid October 22, 2026). Beyond orphan wells, municipalities are soliciting well maintenance and repair: Hillsborough County (ITB-26-00234, water well maintenance and repair, $688,073 estimated two-year value, bids closed June 12, 2026); the City of Austin (IFB 8600-DCG1032REBID, well maintenance for swimming pools, bids due October 1, 2026, local business preference); the Illinois Department of Corrections (multiple quotes for color video survey and well casing repair at Sheridan Correctional Center, with set-aside and non-set-aside versions); and Sarasota County (well abandonment, ITQ 2026QQ759, $50,000 ceiling). New well construction and rehabilitation projects appear in City of DeBary (irrigation system replacement, Bid 03-15, $90,000 estimated cost, April 10, 2015 bid date); City of Albany (Well No. 21 rehabilitation, Bid Ref. 27-032, bids due November 16, 2026); City of Reynolds, Georgia (New Deep Well & Chemical Feed Building, bids due August 14, 2026, BABAA-compliant); and Boulder County (stock water well installation, RFP-300-26, $350,000 contract value, proposals due September 4, 2026). Michigan and Florida show the highest recent posting frequency, followed by Georgia and Mississippi. Orphan well work is federally funded and subject to prevailing wage and Buy America requirements; municipal water projects typically draw on state revolving funds or USDA Rural Development. Prequalification mechanisms are standard in Michigan's orphan well program; competitive low-bid award is typical elsewhere. This code remains active and accessible to contractors with well licensing, environmental compliance capability, and prevailing wage readiness.
