The United Nation’s world water development report, Water for a Sustainable World (2015), illustrated the 55% increase of global water demand by 2050. Without effective countermeasures, the word will encounter a 40 percent shortage of water within two decades.
In Canada, water waste is the potential trigger of water shortage.
Despite the great abundance of reserved water, Canada has a fixed average precipitation around 537 millimeter per year, less than 1/3 of Japan and 1/2 of the Great Britain (Average Precipitation, n.d.). Four years ago, Canada’s water consumption is approximately 1,130 cubic meters per capita, which is 2 times of Japan, 3 times of Germany and 9.5 times of the Great Britain; four decades later, there will be a one-million-increase of Canadian population (Water Consumption, 2016). As water reserve decreases due to the continuously increasing population, water waste remains the trigger of potential hazard for water shortage.

While about one tenth of all water withdrawn served municipal purpose, Canadian families on average consume twice the water as families in other industrialized nations. An average Canadian household uses about 26,000 liters water per month and…
