The City of Toronto has received thousands of complaints as a result of increased rainfall. Although wide-scale retrofits are being conducted throughout the city to mitigate the risk of flooding, homeowners must do their part to flood-proof their homes. As the number of homeowners installing basement flooding prevention devices grows, an increase in pressure is being placed on our sewer system, making homeowners who have not yet installed such devices more susceptible to basement flooding during extreme rainfall. To help ensure your property is flood-proofed, the City of Toronto has set this year’s subsidy funding to $3400 per property. Upgrades include the installation of a backwater valve to prevent the backup of human waste in your basement and sump pumps which help manage water around your foundation. Homeowners are encouraged to contract their insurance broker and to review their insurance policy for information on recent policy changes.

Thousands of homeowners have taken advantage a free Flood Prevention Assessment with Regional Stormwater Management Corporation. An independent Flood Prevention Specialist will assess the characteristics of your home and help you identify whether your home qualifies for the subsidy. Every home is different, and the specialists will help you determine which devices are right for your home. Each property owner will receive on the spot advice, a written estimate, and information on scheduling a Drainage Contractor.
This increased damage resistance is achieved through improvements in codes and standards, designs, methods, and materials used for new construction and post-disaster repair and recovery.
• Surface water flooding which occurs when heavy rainfall overwhelms the drainage capacity of the local area.
• Sewer flooding that occurs when sewers are overwhelmed by heavy rainfall or when they become blocked. The likelihood of flooding depends on the capacity of the local sewerage system. Land and property can be flooded with water contaminated with raw sewage as a result. Rivers can also become polluted by sewer overflows. • Groundwater flooding that occurs when water levels in the ground
• Sewer flooding that occurs when sewers are overwhelmed by heavy rainfall or when they become blocked. The likelihood of flooding depends on the capacity of the local sewerage system. Land and property can be flooded with water contaminated with raw sewage as a result. Rivers can also become polluted by sewer overflows. • Groundwater flooding that occurs when water levels in the ground rise above surface levels. It is most likely to occur in areas underlain by permeable rocks, called aquifers. These can be extensive, regional aquifers, such as chalk or sandstone, or may be more local sand or river gravels in valley bottoms underlain by less permeable rocks.

Floods are part of nature. It is not technically feasible nor economically affordable to prevent all properties from flooding. Therefore a risk-based approach is taken to achieve the best results possible using the budget and resources available. Our aim is to minimize the harm caused by flooding. This involves reducing the likelihood of flooding and reducing the impacts when flooding occurs. At the same time there are underlying pressures that are increasing risk, such as climate change, housing development or changes in land use.
A downspout disconnection simply intersects an existing downspout which currently discharges into the combined sewer and diverts it away from the building to allow the surface water to naturally soak into the ground.
Downspout disconnections are a very simple and cheap way of diverting rainwater out of sewers to a nearby permeable area which should be downhill of the downspout and away from other properties. Rainwater butts and downspout planters or raised rain gardens can add value to a downspout disconnection by storing and reusing water within your garden. This would have the additional benefit of reducing your water use because you would need to water the garden less often.
Your downspout should be disconnected to a permeable area at least 2m away from any building. The infiltration area should be sloping away from properties and roads The slope of the drain should not be greater than 1m vertical for every 50m horizontal (2%) to ensure the run-off has opportunity to soak into the ground. The existing discharge point should be capped to prevent rain water entering the combined sewer.
All gutter downspouts must be disconnected from the combined sewer system at the point of sale of the home. Recently, the city updated the bylaw to ensure that these disconnections are complete by December 3, 2016.
Disconnecting downspouts can greatly reduce the amount of stormwater entering the sewer system. It is also an important step in reducing the risk of basement flooding and releasing polluted rainwater into our local waterways. A downspout is a pipe that carries rainwater/snowmelt from the roof of your home or gutters into the sewer system via a drain pipe connection.
In the wake of disasters, people often wonder whether there is a way to protect both people and property from such devastating losses. Mitigation is the way to provide that protection. Hazard mitigation means taking action to reduce or prevent future damage, preferably before a disaster strikes.
There are three important elements to help reduce the impact of disasters on our nation's citizens and communities:
Disconnecting your downspout is one of the easiest things you can do to help reduce stormwater runoff.
When your gutter downspouts are connected to a pipe, all rain water from your house or building is delivered into the sewer system within minutes. Downspouts that drain on driveways also often drain directly to the stormwater system. The runoff from your house contains pollutants and contaminates that can harm water quality. Disconnecting your downspout will reroute the runoff into rain barrels, cisterns, or permeable areas like your yard or rain garden instead of the sewer. By disconnecting the downspout you are not only helping pollutants to be filtered from the water, but you can also help prevent basement backups and sewer overflows.
By signing up for this incentive offer, your property will be assessed to see if disconnecting your downspouts and installing a rain barrel is possible. You can then use the stormwater that this rain barrel will collect to water your garden or wash your car. Or you can just leave it be and know that it is collecting stormwater that would have normally rushed into our sewer system and overwhelm it. Free disconnections are offered to homeowners who isolate their homes from the of Toronto's sewer systems.
Thank you for your interest in climate change adaptation. We are still accepting applications for the free downspout disconnect/rain barrel incentive from residential property owners in the City of Toronto, You can sign up for the incentive by calling 1-866-392-6097 to have your downspout appointment registered.
Floods are the most frequent natural hazard in Toronto. Just because your home hasn’t flooded yet doesn’t mean it won’t this year. Homes in low-risk areas account for 25% of all flood claims. And in a high-risk area, your chances of flooding during a 30-year mortgage are 1 in 4.
As little as two inches of water can cause devastating damage to your home, and most homeowners insurance won’t cover it.
Here in Toronto, rainstorms, melting snow, and flash floods create the highest flood risk. In addition, new land developments of buildings increase our risks dramatically.
On average, 80% of the cost of eligible flood prevention solutions are reimbursed by City of Toronto up to a maximum of $3,400. Upgrades include the installation of a backwater valve to prevent sewer backup, and the replacement or installation of a sump pump and backup battery to help manage water around your foundation. The City of Toronto is encouraging residents to take appropriate action to reduce the risk of basement flooding.
