Need Landfill Gas, Bio-Gas Or

Other Renewable Natural Gas (RNG) Pipeline Services?

USDI supports many owners and producers of RNG through successful design and operation of their RNG pipelines, from the plant to the end user.  Whether the end user be another pipeline, local gas distribution system, or a private customer, USDI can provide a tailored solution to fit your budget.

USDI is the leading provider of jurisdictional RNG pipeline design, operation and maintenance services across much of the United States.  We currently work with nearly thirty (30) RNG pipeline facilities across Illinois, Nebraska, Wisconsin, Missouri, Michigan, Ohio, Pennsylvania, Kentucky, Virginia, Tennessee, North Carolina, Arizona, Texas and Indiana.  Many of these pipelines carry unprocessed landfill gas, however, there are several that process, clean, and compress the gas to pipeline quality.  USDI also works with pipelines that move RNG created from sources other than landfills, such as methane from animal waste and anaerobic digestion of grass or other stock.  USDI is your full service RNG resource.  Our teams of registered professional engineers and technicians can provide design, inspection, construction, and complete operation of your pipeline(s).  If you need assistance on the production side of the pipeline, USDI has successfully partnered with several experts in the production field and can work with you to find an appropriate solution.
