Ottawa - Thermal-electric power producers remained the country's dominant user of water in 2011, according to the latest results from Statistics Canada’s Industrial Water Survey, released July 2, 2014.
Data from the Industrial Water Survey show that the three main industry groups covered by this survey had a total water intake of 27.6 billion cubic metres in 2011. Power producers accounted for 85.1% of this total, manufacturers 13.3% and mines 1.6%.
Among manufacturers, five industries accounted for almost 95% of the sector's water intake in 2011: the paper, primary metals, chemicals, food, and petroleum and coal industries.
The vast majority of the intake was returned to the water supply. Total water discharge for the three main industry groups in 2011 was 26.9 billion cubic metres. Thermal-electric power producers accounted for 85.8% of the total, manufacturing industries almost 12% and mining industries 2.2%.
Prior to discharge, these same industries recirculated 6.0 billion cubic metres of water. Thermal-electric power producers accounted for 61.4% of this total, manufacturing industries 30.9% and mining industries 7.7%.
The three groups had water costs totalling $1.4 billion.
