WHY SEWER HEAT RECOVERY?

Reduce energy costs and carbon emissions and increase energy efficiencies

The wastewater from a sewer system is a relatively stable and moderate temperature making it a reliable thermal heat source and sink that can be coupled with heat pumps to provide both heating and cooling to buildings.

TECHNOLOGY IN ACTION

National Western Center in Denver, CO.

The Sewer Heat Recovery System that CenTrio operates is the Largest in North America with a total capacity of 12MW+ including supplemental heating and cooling. The Campus is a 250-acre urban hub and is a destination for agriculture, education, and entertainment.

Greenfield Development Project

The system is designed to provide a foundation for future system expansion of the campus and neighboring developments.

Ambient Loop Design
