Mandatory Downspout Disconnection

Benefits

Everyone benefits from downspout disconnection

Rainwater runs off a roof, flows through the eavestroughs and discharges either onto the property (if the downspout is already disconnected) or into a downspout that carries it directly into the sewer system. During heavy rainfall, if the downspout is connected, the sewers become overloaded, increasing the risk of basement flooding and releasing polluted rainwater into our local waterways.

To help deal with the problem, the City has made downspout disconnection mandatory, city-wide. It is being introduced in three phases, beginning with the central area of the city, where stormwater and sanitary drainage are combined into a single pipe.

Disconnecting your downspouts will help reduce the amount of stormwater sent through the sewer system. Less stormwater can help prevent wastewater from backing up and thus reduce your risk of basement flooding.

Rain garden

Using less water, keeping rainwater on your property and managing what and how much goes into our storm sewer system means you are protecting your home and the environment at the same time. One way to do this is to plant a water-efficient, natural garden. For tips to get started, consult the City's water-efficient landscaping information.
