Wastewater heats KLO campus

by okanagancollegesustainability

In 2004, Okanagan College’s Facilities Management ran clear water lines from the City of Kelowna Waste Water Treatment Facility to the KLO campus boiler house. Now our college extracts the heat from the clear water to contribute heat to the surrounding buildings. This is achieved by using heat recovery chillers and “harvesting” heat from the clear water.

In addition, we replaced old boilers with high efficiency boilers and replaced old cooling units containing environmentally hazardous refrigerant with new high efficiency, environmentally friendly cooling units. These steps, along with many others to come, greatly reduce energy consumption and pollutant discharge equivalent to 819 tonnes of carbon dioxide annually.
