Persigo Wastewater Treatment Plant (WWTP) Gas System Upgrade

Did you know, Symbiont’s Construction Group has constructed more than 70 biogas facilities in 29 states?  To date we have completed over $360 million in renewable energy work.

Persigo Wastewater Treatment Plant (WWTP) Gas System Upgrade

Symbiont provided a biogas upgrading system for the Persigo wastewater treatment plant (WWTP).  The project consisted of upgrading the biogas system and dedicated RNG pipeline that crossed through a developed part of Grand Junction.  Symbiont provided permitting, contract administration, and construction management services, as well as directed system commissioning and start up.  Additional work included an option to preferentially use BioCNG™ in the WWTP digester boiler instead of natural gas, thereby saving on treatment plant operating costs.

The BioCNG™ system produces about 500 GGE per day from WWTP digester gas, which is piped about 6 miles to Grand Junction’s existing CNG fueling station.  The BioCNG™ is used as fuel for a fleet of buses owned by Grand Valley Transit (GVT) and for City refuse trucks, street sweepers, and general utility pickups.  These vehicles are fueled at the Grand Junction facility.  Grand Junction and GVT continue to purchase additional CNG vehicles to increase the overall CNG fleet.

“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,” said Rich Englehart, Grand Junction’s City Manager.  “This project will help control the City’s potential fuel price escalation.”
