The extraction of waste heat from treated municipal wastewater is a promising technology that has seen only limited application in Canada. A District Energy System for the Whistler Athletes' Village was developed that utilizes waste heat available in the treated municipal wastewater
effluent to provide more than 95% of the annual heating requirement for the Village. The system is unique in that it extracts lowtemperature ambient heat from wastewater, making it flexible enough to provide both heating and cooling in what is now a District Energy-Sharing System (DESS). The
installed DESS is one of the first closed-looped heating and cooling district energy systems in the world. What is abundantly clear from the Whistler Athletes Village Waste Water Heat recovery project is that wastewater heat recovery is a viable source of renewable energy.
