UNSPSC 71131103: Matrix organic cleanup services

Services using organic clay acid stimulation fluid to stimulate the matrix.

UNSPSC 71131103 Matrix organic cleanup services is a Commodity code that encompasses construction and installation of landfill gas collection and control infrastructure, including gas extraction wells, piping systems, condensate handling equipment, and related appurtenances. State and local governments soliciting under this code include solid waste authorities, municipalities, and water reclamation districts managing landfill operations and anaerobic digestion facilities. The work involves surveying extraction well locations, installing HDPE-cased wells with perforated horizontal collectors, laying lateral and conveyance piping in multiple diameters, installing wellheads and condensate sumps with pneumatic equipment, and performing site preparation including slope seeding and erosion control. Bidders must hold state licensure (General Contractor licenses where required), demonstrate minimum five years of direct experience in similar landfill gas or digester gas projects, and complete at least five comparable projects within the preceding five years. Contracts typically require performance and payment bonds equal to a percentage of bid price, compliance with state environmental and security statutes, workers' compensation and general liability insurance, and E-Verify verification for employees.

Recent activity centers in Georgia and California. The Dalton-Whitfield Solid Waste Authority issued an ITB in April 2026 (due May 21, 2026) for landfill gas collection and control system expansion at its Old Dixie Highway Municipal Solid Waste Landfill in Dalton, Georgia, encompassing approximately 4,100 linear feet of perforated collectors, 7,420 linear feet of lateral piping, condensate sumps, wellheads, and side-slope stabilization across a 150-calendar-day completion timeline with liquidated damages of $2,000–$5,000 per day. The Eastern Municipal Water District in Riverside County, California issued an RFP in February 2026 (due April 13, 2026) for a long-term Design-Build-Finance-Own-Operate-Maintain agreement to convert digester gas at three Regional Water Reclamation Facilities into renewable natural gas, requiring proposers to demonstrate five years of direct DBFOOM digester gas experience, post bid bonds estimated at $20 million, and achieve no less than 90 percent gas utilization. Both opportunities require mandatory pre-proposal conferences and site visits, unit-price or performance-based cost evaluation, and compliance with applicable air quality and prevailing wage requirements.
