CenTrio delivered a first-of-its-kind project at Denver’s National Western Center, the largest sewer heat recovery system in the U.S. This bold solution transforms waste into energy, providing over 12MW of heating and cooling capacity. We specialize in bringing creative, class-leading technologies to market, proving that complex designs can become award-winning realities.
This innovative campus environment sets a global benchmark for sustainability. By utilizing an ambient loop to draw energy from sewer lines, the system reduces carbon footprints by 70% and water consumption by 80%. Awarded the P3 "Best Constructed Project of the Year," it serves as a model for how academic and municipal facilities can achieve aggressive decarbonization goals.
As the 90% equity provider and operator under a 40-year agreement, CenTrio ensures long-term alignment with our partners. Our U.S. Private Placement financing structure provided an attractive cost of capital, allowing for a secure, transparent build-up of costs. All construction and operations were delivered on time and on budget, ensuring project success and reliability.
“Knowing we’ll have to heat and cool our buildings one way or another, we chose an innovative, clean-energy system that virtually makes something from nothing.”
Our Sustainability & Impact Annual Report tracks progress while our Sustainable Infrastructure Plan maps out a comprehensive decarbonization roadmap to guide our activities.
We recognize the power of community connection. We build positive relationships through economic organization alliances, local event sponsorship and service, and educational workshops.
We operate the largest ice battery system in North America, maintaining comfortable building temperatures year-round and reducing electricity costs for thousands of end-users.
We displace fossil fuels by harvesting heat energy from wastewater. Our ambient loop captures thermal sewer flows, transforming the NWC into a bold, low-impact sustainable landmark.
