Basement Flooding Protection Subsidy Program

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:

• Installation of a backwater valve.
• Installation of a sump pump.
• Severance and capping of a home’s storm sewer or external weeping tile connection.

Disconnecting the downspouts from your property’s eavestrough system is not eligible for a subsidy.

Eligible Work

Backwater valve

• Installation or replacement of backwater valve.
• Installation of alarm for backwater valve.

The available subsidy is 80 per cent of the invoiced cost up to a maximum of $1,250 regardless of the number of devices installed at the property, including eligible labour, materials, permit and taxes.

A Building Permit is required to install a backwater valve. The valve must pass inspection by the City of Toronto building inspector, in order to be eligible for the subsidy.

You must also consent at the time of the building inspection or at the request of the City:

• To provide City access to the backwater valve to verify that installation has been completed in accordance with the requirements and conditions of the Program.
• To the City taking photographs, video and digital images of backwater valves.

Selecting a Contractor

Homeowners are strongly encouraged to conduct due diligence before hiring a contractor. It is recommended you obtain a minimum of two quotes as well as references before hiring a City of Toronto licensed contractor.

Before work starts, verify that your contractor has a valid City of Toronto business license using the Business Licence Lookup tool or by phoning 416-392-6700.

If your contractor does not have a valid City of Toronto license, you will be denied funding for the work completed.

Different types of contractors are licensed to perform different types of eligible work:

Protecting Flood Prevention Devices & Your Basement

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.
