During heavy rain, the sewers can become overloaded. It is essential that homeowners take appropriate action to reduce the risk of basement flooding.
The City offers owners of single-family, duplex and triplex residential homes a subsidy of up to $3,400 per property to install flood protection devices. Eligible work includes:
Disconnecting the downspouts from your property’s eavestrough system is not eligible for a subsidy.
The City offers a subsidy of up to 80% of the invoiced cost, up to a maximum of $1,250, to help offset the cost of installing a sump pump. This subsidy is regardless of the number of devices installed at the property, including eligible labour, materials and taxes.
A Building Permit is required to install a backwater valve. Before work starts, verify that your plumber has a valid City of Toronto business licence using the Business Licence Lookup tool or by calling 416-392-6700. The valve must pass inspection by the City of Toronto building inspector in order to be eligible for the subsidy.
It is critical that backwater valves are maintained and regularly inspected according to product specifications.
You must also consent at the time of the building inspection or at the request of the City:
Backwater valves are designed to close the sewer line during periods of extreme rain to prevent water from entering your home. When the valve is closed you should not use any plumbing fixtures (i.e. toilets, sinks, dishwasher, washing machine) because water will not drain and will back-up into your home.
The City offers a subsidy of up to 80% of the invoiced cost, up to a maximum of $1,750, to help offset the cost of installing a sump pump. This subsidy is regardless of the number of devices installed at the property, including eligible labour, materials and taxes.
Be sure to maintain basement flooding protection devices according to manufacturer instructions. Keeping these devices in good working order is an important step in protecting your home against basement flooding.
Install a properly-sized sump pump to help pump water collected by the weeping tile system to an area outside. Make sure the sump pump empties onto a permeable surface at least two metres from the foundation wall.
Sump pumps can lose power during severe storms, so you may wish to consider a battery back-up. They also need to be inspected and maintained according to product specifications to ensure optimal performance.

To keep your flood prevention devices in good working order, it is essential to maintain them according to the manufacturer’s directions.
When installing a backwater valve, consider including an alarm, so that you know when the device is activated. When your backwater valve is activated, it works to keep sewer water from backing up into your basement, but it also keeps wastewater from your home from flowing to the sewer. When your backwater valve is activated, any water sent down the drain (through toilets, sinks laundry etc.), may end up in your basement.
As rainstorms and power outages can accompany one another, you may also want to consider battery-power back-up for your sump pump.
