BioCNG LLC says it has been selected to design and build its BioCNG biogas conditioning system and gas pipeline for the Persigo wastewater treatment plant (WWTP) in Grand Junction, Colo.
The BioCNG will be used as fuel for a fleet of buses owned by Grand Valley Transit (GVT) and fueled at the City of Grand Junction facility, as well as city refuse trucks, street sweepers and general utility pickups. The City of Grand Junction and GVT will continue to purchase additional CNG vehicles to increase the overall CNG fleet.
The WWTP, which is jointly owned by the City of Grand Junction and Mesa County, will produce about 500 gallons of gasoline equivalent (GGE) per day from the WWTP digester gas, which will be piped about six miles to Grand Junction's existing CNG fueling station.
‘We are excited about being able to produce our own fuel so we can have a better handle on what our fuel costs will be in the future,’ says Rich Englehart, Grand Junction's city manager. ‘This project will help control the city's potential fuel price escalation.’
BioCNG LLC will engineer the system, obtain all necessary permits, manage the construction, and commission and start up the system. Future work may include investigation of an option to modify BioCNG system tail gas for use in the WWTP digester boiler, thereby saving on treatment plant operating costs.
