About the Challenge

The Mille Îles River, located north of Montreal is 42-kilometers long, extends across 9 distinct urban and agricultural areas, and provides drinking water to over 450,000 citizens. It is home to fragile flora and fauna which are essential to healthy river ecosystems but also faces environmental challenges caused by wastewater and other pollution sources. The developed solutions will meet local needs while having the potential to scale and have global impact.
