UNSPSC 71131108: Matrix treatment diversion services

Services to administer matrix stimulation injection treatments to ensure a uniform distribution of treatment fluid across the treatment interval.

UNSPSC 71131108 Matrix treatment diversion services is a Commodity code that state and local governments use to classify landfill gas collection, control, and utilization projects. Recent solicitations show that issuing bodies are procuring comprehensive infrastructure for extracting landfill gas from municipal solid waste facilities, converting digester gas from water reclamation plants into renewable energy, and operating long-term gas management systems. Work includes surveying well locations, installing gas extraction wells with piping and lateral systems, condensate handling equipment, monitoring and control infrastructure, and site restoration. Issuing bodies under this code include special-purpose solid waste authorities and water reclamation districts. The Dalton-Whitfield Solid Waste Authority in Georgia, for example, issued an Invitation to Bid (ITB) on April 17, 2026, for landfill gas collection and control system expansion at its Old Dixie Highway Municipal Solid Waste Landfill, with a bid deadline of May 21, 2026, and mandatory pre-proposal conference on May 1, 2026; the scope included approximately 4,100 linear feet of 6-inch perforated horizontal collectors, 7,420 linear feet of lateral piping, 25 liquefied fossil gas wellheads, condensate sumps, and seeding and erosion control over 46,100 square yards. Qualifying contractors must be Georgia-licensed General Contractors with a minimum of five years' experience in landfill gas collection and control system construction, having completed at least five similar or larger projects within the past five years.

Geographic activity is concentrated in California and Georgia. The Eastern Municipal Water District in Riverside County, California issued a Request for Proposal (RFP) on February 24, 2026, for a Design-Build-Finance-Own-Operate-Maintain agreement to develop and operate a Digester Gas Utilization Project at three Regional Water Reclamation Facilities, converting digester gas into renewable natural gas or other marketable energy with a proposal deadline of April 13, 2026, and anticipated substantial completion by June 2029. The Dalton-Whitfield Solid Waste Authority project in Georgia requires Substantial Completion within 120 calendar days of Notice to Proceed and final completion within 150 calendar days, with liquidated damages of $2,000 per day for the first 90 days following Substantial Completion and $5,000 per day thereafter. Contractors must comply with state-specific regulations, including the Georgia Security and Immigration Compliance Act and California prevailing wage requirements for public works components. The source shows limited recent activity under this code, with only two directly relevant solicitations in the 2026 record and no state or local contract opportunities for matrix treatment diversion services in the traditional sense.
