The three industry groups covered by this survey had a total water intake in 2007 of nearly 32.9 billion cubic metres, enough to fill more than 13 million Olympic-sized swimming pools.
Thermal-electric power producers accounted for 84.5% of this intake, while manufacturers withdrew 13.9%, and mines took 1.6%.
Among manufacturers, five industries accounted for almost 93% of the water intake in 2007: paper, primary metal, chemical, petroleum and coal and food.
The three main industry groups discharged 32.2 billion cubic metres in wastewater in 2007. Thermal-electric power producers accounted for 84.9% of the total, manufacturing industries 12.8%, and the mining industries 2.3%.
These industries recycled about 9.2 billion cubic metres of water. The thermal-electric power producers accounted for 47.7% of this total. Manufacturing industries recycled 29.1% and mining industries the remaining 23.2%.
The three groups had total water costs amounting to $1.57 billion.
Note: The 2007 Industrial Water Survey was conducted under the umbrella of the Canadian Environmental Sustainability Indicators project, a joint initiative of Statistics Canada, Environment Canada and Health Canada. The survey gathered information on the intake and discharge of water by three groups of industries: manufacturing, mining and thermal-electric generating industries. It collected information on sources of water, purposes for which the water was used, whether water was re-circulated or re-used, where the water was discharged and what treatments were used. It also collected information on water acquisition costs, treatment costs and operating and maintenance expenses related to water intake and discharge.
Definitions, data sources and methods: survey number 5120.
