Recirculation rate = Amount of recirculated
water as a percent of intake. The same water can leave a sub-system and re-enter
it or is used in another sub-system many times, resulting in a recirculation
rate > 100%.
Gross water use = Intake + Recirculation.
Consumption = Intake - Discharge.
Consumption rate = Consumption as a percentage
of Intake.
Atlantic provinces include: Newfoundland and
Labrador, Prince Edward Island, Nova Scotia and New Brunswick.
Prairie provinces include: Manitoba, Saskatchewan
and Alberta.
British Columbia and territories include: British
Columbia, Yukon, Northwest Territories and Nunavut.
Note(s):
Thermal-electric power generation is defined as fossil-fuel electric
power generation (North American Industry Classification System, code 221112)
and nuclear electric power generation (North American Industry Classification
System, code 221113). Figures may not add up to totals due to rounding.
