Municipal treatment of drinking water is the key to community health, but it can have hidden toxins as well
by Emily Walsh in collaboration with the Alberta WaterPortal
Clean drinking water is something many of us take for granted, while others go to great lengths to protect and restore our natural water resources. The Centers for Disease Control and Prevention (CDC) estimates that 780 million people around the world lack access to a treated water source.1 This does not take into account the treated water billions of people have access to that still contains harmful toxins. Below is a list of toxins sometimes found in tap water and how they get there.
The good, the bad, and the government: political response to the water crisis in Cape Town
This is a summary of the presentation delivered by Kim Sturgess at The Schulich School of Engineering at the University of Calgary on June 4th, 2018.
In early 2018 the world’s interest and anxiety was captured by the announcement of Day Zero and the online clock counting down toward the projected time when the household taps of Cape Town would have to be turned off and water would be delivered by truck to city residents. Media around the world began talking about water scarcity and examining factors threatening the water supply of other cities. There was a general increase in awareness that municipal water supply could run out and what that could mean for a city. This global ‘conversation’ about water scarcity was a good thing, but there have also been negative consequences to the sensational announcement of #dayzero.
Corporate Water Stewardship: a crucial part of global water security

Commercial and Industrial Water Use and Water Related Risks
Companies that make up the industrial sector and commercial sectors play a significant role in water use. In Alberta, approximately 38% of water allocations are for commercial and industrial activities.1 This number excludes companies that receive their water from municipalities and from irrigation districts. Across Canada, industrial activities withdrew 30.2 billion m3 of water in 2013, approximately 85% of this was for thermal electric generation.2 Almost all of the water withdrawn for these industrial activities was returned to the environment, as seen below in Figure 1.
Words of Wisdom from Alberta's Aqua Champion, Kim Sturgess
We are still buzzing with inspiration after Kim Sturgess’s convocation speech yesterday after receiving an Honorary Degree of Law from the University of Calgary. Kim provided the engineering graduates with a few words of wisdom as they start on their career paths, but professionals of all experience levels can benefit from her lessons.
1. Live where your heart is happy – For Kim, this is Alberta. From her first summer in mountains as a young summer student, she knew she was home. Find where your heart is happy and make this your home.
2. Follow your passion – Even when your ideas are met with discouragement or confusion, as many great ideas often are, find your supports and follow what you believe in.
3. Honor your profession – An engineer holds a great deal of responsibility and accountability. Be sure to follow the code of ethics and take all responsibilities seriously.
4. STEM starts at home – In the words of Kim, “when that little one comes home and says “I want to be an engineer”, say "fantastic, what can I do to make that come true for you”. Encourage children to follow their passion in STEM from a young age, and do what you can to support those dreams.
In the words of Aritha Van Herk, “with infectious passion, [Kim] has made water her inspiration and spirit … this woman who resonates water’s bright grace, its flow and murmur, and its wellspring importance.” Congratulations Kim.
The Connected Home and Water: How IoT Technology Helps Conserve and Protect
by Nadine Evans
It is no secret that Canadians aren’t exactly great at water conservation. We are among the world’s largest water wasters, consuming twice as much water as Europeans, which may be in part due to the abundant supply of fresh water in Canada. In fact, nearly 10% of the world’s renewable water is located here, despite us housing less than 1% of the world’s population (Source). Water scarcity isn’t something that Canadians often worry about.
However, with water utility prices continuing to rise and a global water crisis looming, many homeowners have begun to re-examine the practice of water conservation.
First, let’s consider how water is used in a home. There’s obvious water wasting habits, such as running water while brushing your teeth, taking unnecessarily long showers, or watering your lawn when rain is expected. While these habits all add up to significant waste, did you know that one of your biggest water wasters is often hidden? Most homeowners are surprised to learn that 13% of a home’s water usage is lost due to leaks, many of which go undetected for some time, leading up to significant water loss.
