Learning about cool water in T.O.

November 28, 2018

Around 50 members of CIPH’s Industrial PVF Council and Canadian Water Systems Council took in a tour of the Enwave Deep Lake Cooling Pump Station and Toronto Water during November’s networking luncheon.

”We are just using physics,” explained Alex Sotirov (pictured right), Enwave’s vice-president of engineering. ”We’re just moving energy.”

The Deep Lake Cooling system takes water from Toronto’s water supply at 4°C, passes it through a set of heat exchangers, and returns it to the municipal supply at 12°C, using that energy to heat and cool buildings in the city’s downtown.

“We borrow the water through a heat exchanger for a short time,” explained Sotirov. The system, which went online in 2004 and uses the John St. Pumping Station for its supply of energy, continues to expanding its customer base.
