Drinking Water: Joint Assessment

OBJECTIVE: Achieving economies of scale through inter-municipality collaboration, while developing a deeper understanding of the threats to a shared water source.


ACTIONS: Development and coordination of a vulnerability analysis for six drinking water intakes from 11 municipalities collecting their water in the Rivière des Mille Îles, on the North Shore of Montreal. This entailed careful consultation and meetings with elected officials and water stakeholders in a highly urbanized area with multiple challenges. 400,000 people drink water from the Rivière des Mille-Îles.
