RNG equipment installed at City of Longmont WWTP

Biogas project in final stages

The City of Longmont reached another milestone with its Biogas Treatment and Renewable Natural Gas (RNG) Fueling Station Project in November when general contractor CGRS set the biogas-treatment equipment on the Wastewater Treatment Plant (WWTP) site.

This new equipment will clean the biogas – a byproduct of the wastewater-treatment process – and turn it into RNG before it’s piped to the City’s new RNG Fueling Station. Equipment at that station that will compress the RNG into fuel for use in the City’s trash truck fleet.

After the biogas-treatment equipment was anchored to the concrete pads, mechanical contractors installed stainless steel piping that will carry the biogas from the digester to the new biogas-treatment equipment. Electricians were also onsite to finish the new electrical duct bank and pull wire from the control panel to the biogas-treatment equipment.

At the RNG Fueling Station and administration building, crews worked on paving the site’s drives and parking lot and installed the flooring, landscaping, sprinklers, irrigation, plumbing, fire sprinklers, and electrical service. The roof was installed on the front entrance vestibule, and CNG tubing was run to the fueling bays, which also received their conduit and alarm devices.
