WEF Project Excellence Award

Tuesday, October 19

Carollo and the City of Longmont will be honored with the 2021 Project Excellence Award for the design of the Longmont Biogas Treatment and RNG Fueling Station Project.

The project was part of a proactive pursuit of city-wide sustainability objectives by maximizing the use of energy-laden biogas. This biogas-to-renewable natural gas (RNG) project equipped the city’s wastewater treatment plant with a biogas upgrading system that conditions and converts the biogas into RNG, which is then transferred to a newly constructed vehicle-fueling station that serves the City waste services department’s new natural-gas-fueled trash and recycling trucks.

As a result, the City continues to proactively meet the promises of their sustainability plan and tangibly benefit local communities, all while recovering and reusing valuable resources.
