1.
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%.
2.
Gross water use = Intake + Recirculation.
3.
Excluding sand, gravel, clay, and ceramic and refractory minerals mining and quarrying (North American Industry Classification System, code 21232).
4.
Atlantic provinces include: Newfoundland and Labrador, Prince Edward Island, Nova Scotia and New Brunswick.
5.
Prairie provinces include: Manitoba, Saskatchewan and Alberta.
6.
British Columbia and territories include: British Columbia, Yukon, Northwest Territories and Nunavut.
