A better future starts with water

Imagine a world where the single biggest barrier to a child’s health, education, and future is not money or politics. It is water.

For more than 2 billion people, that is reality.

Safe drinking water is the starting line for opportunity. Without it, children struggle to stay in school, families lose income to preventable illness, and entire communities are held back from reaching their potential.

Learn About Our Impact

Our model is highly cost-effective

For less than $0.38, we can help improve a person’s water, sanitation, or hygiene,
creating healthier families and stronger communities.

Because when knowledge is shared, it multiplies.

CAWST delivers the knowledge that makes it possible

From our headquarters in Calgary, we equip organizations and communities around the world with the training, tools, and expertise to keep water safe for life.

As a licensed professional engineering firm and Canadian charity, we combine technical expertise with open-access knowledge to help communities solve water challenges themselves.
