Downspout disconnection
Downspouts that are connected to the sanitary sewer system are in conflict of Region of Peel Bylaw 53-2010 and should be disconnected.
A downspout is a pipe that carries rainwater from a roof to ground level or into the ground or sewer system.
Not every downspout that goes into the ground is necessarily connected to the sanitary sewer system.
The Region might perform a downspout survey or smoke testing to confirm the connectivity.
The benefits of disconnected downspouts
Disconnecting a downspout that’s connected to the sewer system is an easy way to protect your home.
By disconnecting a downspout you’ll:
- Help keep excess rainwater out of Peel’s sewer system, which reduces the risk of flooding.
- Improve the water quality flowing to local streams and rivers.
- Give your lawn and garden a free source of water.
Disconnecting a downspout lets storm water flow away from your home’s foundation onto gardens, landscaped areas and lawns on your own property. The water then slowly soaks into the ground, where it is naturally filtered and returned to the water table.
Options for disconnecting your downspout
Region of Peel staff will disconnect your downspout free of charge if it is found to be connected to the sanitary sewer system. Or you can disconnect it yourself.
Disconnecting a downspout on your own
As a property owner it’s your right to disconnect your own downspouts if you wish.
Disconnect your downspout on your own if:
- You can disconnect it safely, without causing a hazard for you or your neighbour.
- You can point the downspout away from your home’s foundation.
- You can keep the flow of your disconnected downspout directed away from your neighbor’s property.
Disconnection by the Region
This program is fully operated by the Region. Homeowners do not need to pay for the disconnection or take any other action.
A Regional staff member or contractor will:
- Identify the connected downspouts.
- Determine the most effective way to disconnect.
- Perform the disconnection work.
This work will be performed in close communication with you. Any downspout that is found to be directly connected to the sanitary sewers will be disconnected as per the requirements of the mandatory program.

Capping your standpipe
Capping prevents stormwater from entering the system after downspout disconnection but also is a safety measure to ensure debris and small animals do not enter the opening.
Standpipes can be constructed of plastic or clay and will have different diameters, which will be specific to your property.
Caps and plugs come in a variety of styles and sizes which are available at many hardware stores or plumbing supply stores. Measure the diameter of your standpipes before visiting the store to purchase caps or plugs. Property owners can use:
- A rubber cap secured by a hose clamp or a PVC or nylon cap
