A New Way to Manage Stormwater

We're engaged in a ground-breaking research study in an effort to improve stormwater management, introduce savings, and address the impacts of urbanization, degraded water quality and climate change.

The project, “Stormwater Economic Optimization Study” began in 2018 and is scheduled for completion in 2020.

Background

Stormwater management is primarily the responsibility of municipalities. Unfortunately, most municipalities have not been able to allocate the necessary funds to manage stormwater because of competition with other priorities.

This inadequate funding has led to a $6.8 billion stormwater infrastructure deficit​ in Ontario alone.

What Do We Hope to Accomplish?

Because we know that stormwater does not follow municipal boundaries, we believe that using a cost-benefit approach on a watershed scale may offer opportunities to find efficiencies to address the gap in funding.

This particular project looks at the East Holland subwatershed, which includes the Towns of Aurora, Newmarket, Whitchurch-Stouffville, East Gwillimbury as well as the Region of York.

What’s the timeline?

​Project Stages

  1. Stage 1 (2018)
    • Secure funds, project team and advisory committee
    • Model data compilation and initiate build
    • Initiate life cycle costing
  2. Stage 2 (2019)
    • Complete model build and life cycle costing
    • Optimization modeling and scenarios - preferred management strategies
  3. ​Stage 3 (2020)
    • ​​​​Reporting, outreach and engagement
    • Policy implications and implementation plan
