UNSPSC 71161008: Reservoir models

Creation of models of reservoirs. The model could include any of the geological, fluid or other characteristics of the reservoir.

UNSPSC 71161008 Reservoir models (Commodity) encompasses design, construction, and operational modeling work for water and gas storage systems, though the recent state and local opportunities show the code is being applied primarily to landfill gas extraction system infrastructure and wastewater digester gas utilization projects rather than traditional water reservoir modeling. State and local issuing bodies applying this code include special-purpose districts and municipal authorities — solid waste authorities, water reclamation districts, and city public works departments. The work currently being solicited involves detailed engineering design, installation of collection and conveyance infrastructure (perforated wells, piping networks, monitoring equipment), and long-term operational management contracts for gas extraction, treatment, and energy conversion systems.

Recent activity spans Georgia, Florida, and California. The Dalton-Whitfield Solid Waste Authority issued an ITB on April 17, 2026 (due May 21, 2026) for construction and installation of a landfill gas collection and control system expansion at its Old Dixie Highway Municipal Solid Waste Landfill in Dalton, Georgia, encompassing approximately 7,420 linear feet of lateral piping, 4,100 linear feet of horizontal collectors, 25 wellheads, and associated controls and seeding work. The Eastern Municipal Water District in Riverside County, California issued an RFP on February 24, 2026 (due April 13, 2026) for a long-term Design-Build-Finance-Own-Operate-Maintain agreement to develop and operate a Digester Gas Utilization Project at three Regional Water Reclamation Facilities converting anaerobic sludge digester gas into renewable natural gas or other marketable energy products, with contract terms of either 15 years plus one optional 5-year extension or 20 years with substantial completion by June 2029. A third opportunity, the City of DeBary, Florida irrigation system improvement project, appears unrelated to the code's scope and likely represents a coding error in the source data.
