Who should take action

What it is

A catch basin or storm drain is a drain, often located adjacent to a road. They direct water from the street to the municipal stormwater system.

Catch basins can become clogged with snow, ice, leaves or debris. Plugged drains cause water to build up on streets and sidewalks during heavy rainstorms or when overland flooding is occurring. This can increase flood risk to nearby properties.

Your local government may not be able to regularly monitor all catch basins in your area. Take initiative by sharing the responsibility for this low effort, inexpensive, and rewarding activity.

Benefits

When you monitor and keep a catch basin clear in your neighbourhood, you're helping to prevent flooding on your street, in your home and community. You can encourage others to do the same. Strike up a conversation with a neighbour or promote the activity at a community event such as a neighbourhood cleanup day.
