After six years of work, the Deep Lake Water Cooling project in Toronto, will pump water near freezing temperatures from 83 meters below the surface of Lake Ontario for use in cooling up to 100 office buildings or 8,000 homes in downtown Toronto before being treated for use as drinkling water. Enwave, the company responsible for the project is co-owned by the City of Toronto and says the project "reduces electricity use by 75 per cent and will eliminate 40,000 tonnes of carbon dioxide, the equivalent of taking 8,000 cars off of the streets of Toronto."
