Downspout Disconnection Subsidy

Page Summary

In the event of heavy rainfall, downspouts that are connected to the Region's sanitary sewer system (in the ground) can increase the risk of basement flooding.

What are downspouts?

Downspouts are the pipes connected to your eavestroughs that collect water from your roof and directs it to the ground or to a drain below ground.

Difference between a connected and disconnect downspout

Connected downspout

A downspout that is attached to your house and enters into the ground.

Disconnected downspout

A downspout that is attached to your house and discharges to the lawn or other permeable surfaces at a suitable distance away from the outside wall.


Why should I disconnect my downspouts?

Disconnecting downspouts can significantly reduce the amount of rainwater that gets into the sewer system, which will reduce the risk of sewer backup and basement flooding.
