Water use measures the average amount of water used per person on a daily basis.
Why This Matters
The world is facing a significant water crisis as a result of over-consumption, pollution, climate change and population growth in water-stressed regions (Barlow, 2007; Brown, 2011). In Canada, water scarcity is not as imminent as in some other countries; however, proper stewardship and care remains important (Zubrycki, Roy, Venema, & Brooks, 2011).
If water quantity or quality within waterways is too low, the well-being of organisms and ecosystems can be affected. Instream flow needs, the amount of water required to support aquatic organisms and their habitats (e.g., wetlands), can be threatened by large-scale human consumption (Morris et al., 2007; UNESCO, 2009). For the City of Winnipeg, water flows through a 136-kilometre aqueduct from Shoal Lake 40 First Nation, Ontario, to Deacon Reservoir, on the east side of the Winnipeg floodway. Water is then pumped into the city (City of Winnipeg, 2010).
Water use also has implications for city infrastructure. Cities across Canada have aging water delivery systems, which results in losses during distribution. In 2010, 15.4 per cent of Winnipeg water was unaccounted for, much of this due to leaks (City of Winnipeg, 2010). Homes and businesses are also part of the built environment, and can contribute to reduced water consumption by installing water-efficient appliances and fixtures.
Water consumption is also a basic need. Humans need roughly 50 litres per person per day to meet their basic needs (i.e., drinking water, bathing, sanitation and food preparation) (Gleick, 1996). Winnipeg uses far above that; in 2009, the average water use was 301 litres per capita per day (City of Winnipeg, 2010). This number is slightly lower than the Canadian average. However, Canadian per capita usage is higher than every other country in the world except the United States (Environment Canada, 2011).

Measurement and Limitations
The water consumption rate is calculated as the average number of litres used per capita per day in the City of Winnipeg. These data have been available for each year since 1921 (City of Winnipeg, 2010).
The data presented here include all metered water use in the City of Winnipeg, including business, industry, etc.

6. Ensure access to water and sanitation for all
Clean, accessible water for all is an essential part of the world we want to live in. There is sufficient fresh water on the planet to achieve this. But due to bad economics or poor infrastructure, every year millions of people, most of them children, die from diseases associated with inadequate water supply, sanitation and hygiene.
Water scarcity, poor water quality and inadequate sanitation negatively impact food security, livelihood choices and educational opportunities for poor families across the world. Drought afflicts some of the world’s poorest countries, worsening hunger and malnutrition.
By 2050, at least one in four people is likely to live in a country affected by chronic or recurring shortages of fresh water.
Related Water Use Targets
By 2030, substantially increase water-use efficiency across all sectors and ensure sustainable withdrawals and supply of freshwater to address water scarcity and substantially reduce the number of people suffering from water scarcity
