Enwave Deep Lake Water Cooling

Enwave's Deep Lake Water Cooling (DLWC) system is the world's largest lake-source cooling system, and an alternative to conventional, energy-intensive air conditioning. Customers include Toronto's major downtown hospitals, multi-residential and commercial office towers, entertainment facilities and government buildings.

Three high-density polyethylene (HDPE) pipes along the bottom of Lake Ontario bring raw water from 5 km offshore and a depth of 83 metres into the Toronto Island Water Treatment Plant where it is processed into potable drinking water and then directed to Enwave's DLWC Energy Transfer Station located at the City's John Street Pumping Station. Heat exchangers then facilitate an energy transfer between the cold City drinking water and Enwave's closed chilled water supply loop.

Tour both the City's John Street Pumping Station and Enwave's DLWC Energy Transfer Station and learn more about how the system provides year-round cooling needs to over 100 buildings in Toronto's downtown core while also supplying drinking water to the City through this unique partnership between Toronto Water and the Enwave Corporation.
