City of Boulder Partners with Tetra Tech and CGRS for Biogas Enhancement Project
Biogas produced from wastewater digesters will be converted into renewable natural gas (RNG) for vehicle fuel, delivered to community partners for use after injection into the Public Service Company of Colorado (PSCo) pipeline. Construction began in January and is scheduled for completion later this summer.
The city has contracted with Tetra Tech and CGRS, Inc. to design and build the biogas-to-renewable-natural-gas (RNG)-conditioning system, which will replace the WRRF’s cogeneration system, which is at the end of its useful service life. The project is one of only a handful of similar projects in Colorado.
