Canada has one-fifth of the world’s fresh water, points out World Wildlife Fund Canada—and the third largest supply after Brazil and Russia, notes the United Nations’ Food and Agriculture Organization. Yet that is only 7 percent of the world’s renewable fresh water supply, and “the perception that Canada is blessed with an abundance of freshwater has led to misuse and abuse of the resource,” says Environment Canada (EC).
In fact, such bounty has led to a problematic system of water use in Canada. The Conference Board of Canada finds that out of 16 peer countries, Canada ranks 15th in water withdrawals and earns a “C” grade for usage that is nearly double the average of all of these countries. Only the U.S. fares worse, earning last place and a “D.”
…Canadians pay much less for their water compared with their peers…
Part of the problem is that Canadians pay much less for their water compared with their peers, according to EC figures, averaging 31 cents per cubic metre while many others pay two-to-five times that rate. Germans pay the most at $2.16, notes EC. However, in general, a review of water use in Canada highlights some difficult realities, points out EC. These include:
- 84 percent of the population lives in a narrow southern band, while 60 percent of the water supply flows north to the Arctic Circle;
- Most Canadians live in rapidly growing metropolitan areas, a lifestyle which further stretches limited water supplies; and
- Increasing surface and groundwater pollution is further reducing readily available clean water supplies.
Unless Canadians start consuming less, we may face a water shortage. Yet by global standards, Canada remains lucky.
Water Scarcity Is Widespread
At least 2.5 billion people—more than a third of the world’s population—live in water-stressed areas and lack access to clean water or live without adequate sanitation, according to water-based charity WaterAid. Further, water demand is expected to exceed supply by 40 percent by 2030, predicts Alan Hinchman, chief operating officer at Watercura and a former global market director of infrastructure at GE Intelligent Platforms, one of the world’s leading suppliers of sustainable water and process systems solutions.
For every 1000 gallons of water we use, somewhere between 250 to 1000 more [gallons] were lost by leaking pipes
Municipal water loss in North America ranges between 20 percent to 50 percent, notes Hinchman. “For every 1000 gallons of water we use, somewhere between 250 to 1000 more [gallons] were lost by leaking pipes,” he points out. This helps explain why North Americans have one of the largest water footprints in the world, almost 8000 litres per day. Not surprisingly, Hinchman also predicts “North America has a huge water infrastructure bill coming due.”
Because industrial applications account for most of Canada’s water use, per the Conference Board, food and beverage companies can do their part by minimizing the use of this natural resource.
Tetra Pak’s environment team suggests three strategies:
1) Carefully manage supply chains. Most companies’ direct water use pales in comparison to their virtual water use—the water required to produce every aspect of a product from start to finish. For example, it takes 112, 300 and 400 litres of water, respectively, to produce just 2 slices of toast, 2 strips of bacon and 2 eggs, notes Stephen Leahy, award-winning Canadian author of “Your Water Footprint” and sustainable-business writer for The Guardian. In truth, the supply chain is a primary focus of water stewardship activity for companies.
BlackBerry took steps toward measuring the environmental impact of its supply chain by surveying suppliers to determine their use of energy and water resources. The survey found that more than 41 percent of suppliers already had a water strategy in place, boding well for BlackBerry’s efforts to advance the environmental profile of its products.
2) Increase water recycling and reuse. Manage water quality through responsible wastewater collection, treatment, recycling and disposal. Innovators such as Vancouver-based start-up Axine Technologies, recently profiled in Forbes, are already finding ways to recycle industrial wastewater by removing embedded pollutants. This reduces their likelihood of entering water sources and minimizes the demand on potable water supplies.
3) Identify and eliminate sources of waste. In 2009, Toronto-based Sanofi Pasteur, Canada’s largest producer of vaccines, formed an Energy Task Force to identify water and energy consumption draws on its sprawling Connaught Campus, according to the Ontario Water Works Association (OWWA). The company set an ambitious goal of reducing water usage by 25 percent before 2020 and quickly implemented techniques to reuse and recycle water—and succeeded in reducing consumption by 150,000 cubic metres, or 11 percent, in just two years. Sanofi’s efforts won it the 2013 Award of Excellence for Water Efficiency from OWWA.
Tetra Pak’s new Environmental Benchmarking Service also identifies sources of waste by assessing every aspect of product design, production and operation to help customers improve water usage as well as all aspects of their environmental performance.
By taking these steps to assess water use and encourage businesses to reduce consumption, the current generation of Canadians will ensure future generations will still be able to go kayaking in the nation’s rivers, catch their breath in wonder at the sight of Niagara Falls and skate and play hockey across the lakes in the winter.
