Rain to Runoff: A Stormwater Story

Rain to Runoff: A Stormwater Story is a program from Toronto and Region Conservation Authority (TRCA) that helps students and community groups learn about the impacts of stormwater in a changing climate.

About The Rain to Runoff Program

Where does the rain go?

When it rains, approximately half of the water soaks into the ground — except in urban areas, where there are more hard, paved surfaces and less natural ground to absorb it.

In these areas, the water becomes stormwater runoff, and collects in our storm sewers and waterways.

As stormwater runoff makes its journey, it picks up litter, road salt, car fluids, and other pollutants. During intense rain events, it can also cause flooding and erosion in both natural and human-built environments.

The following video, designed for children and families, provides a great introduction to Rain to Runoff. Get the accompanying e-learning worksheet (for ages 8+).

In-School Rain to Runoff Program:
Peel Region

Rain to Runoff: A Stormwater Story helps students in grades 4-12 understand the impacts of stormwater in a changing climate, and discover how to take action to protect drinking water, wildlife habitat, and more.

The program consists of an in-class presentation, followed by a hands-on activity such as a litter clean-up, microplastics exploration, stream study, or road salt impact assessment.

This free program is currently offered to schools in the Region of Peel only. The program can also be booked in addition to a Watershed on Wheels program.

Please contact peel.education@trca.ca for more information. If you do not see a date on the registration calendar that works for your group, please email to inquire about additional dates or to be put on a waitlist.
