Managing stormwater is a priority for the City. There is also a lot you can do to help manage rain and melting snow, reduce the risk of basement flooding, and support better water quality in our local waterways. By keeping rain and snow out of the sewers, and using it as a resource on your own property, you can also reduce your water bill. There are several ways you can help manage rain and melted snow:

Snow Melt & Flood Prevention

  • During snow melt and freeze–thaw cycles, early action helps reduce the risk of localized flooding and slippery conditions.
  • Clear snow and ice from nearby roadside catch basins when safe to do so, to allow melting snow to enter the storm sewer.
  • Remove slush and standing water from sidewalks and driveways before temperatures drop to reduce the creation of slippery conditions.
  • Ensure eavestroughs and downspouts are clear of snow, ice and other debris and are working properly and downspouts are directed away from foundations and walkways.
  • Shovel snow away from building foundations and paved areas and onto a lawn (not the road), if you are able to do so, to improve drainage, and ensure melting water is directed toward nearby catch basins so it can flow properly — rather than pooling along sidewalks, driveways or low-lying areas where it can create hazardous conditions.
  • Report blocked catch basins or ponding on roads or sidewalks to 311.

    Create a Natural Garden

    Build a healthy, vibrant green space that promotes infiltration of rain and melting snow on your property.

    Landscape to Allow Water Infiltration

    Increase your amount of soft surface landscaping, such as a garden, wood chips or gravel. Where you require a hard surface, consider using pervious asphalt, pervious concrete or interlocking pavers to allow water to seep through the surface down to underlying layers of soil and gravel.

    Disconnect Your Downspouts

    By disconnecting downspouts from the sewer system and directing stormwater onto your property instead, you can minimize the risk of sewer overloads and use the water for your lawn or garden.

    Wash Your Car Responsibly

    The dirt on cars can contain toxic chemicals, heavy metals, oil and grease. Don't let this dirty water run into the storm sewer system and wash your car wisely.

    Learn How the Sewers on Your Street Work

    Catch basins are for rain and melted snow only. Stormwater is collected through catch basins (the square grates on the side of the road). Catch basins lead to storm sewers which release this water – untreated – through outfalls directly into nearby waterways. There are two types of sewer systems in Toronto.

    Know What Not to Flush or Pour Down Your Drain

    Many items we use on a daily basis cannot go down our toilets or drains. If they do get into the sewer system, they can cause basement flooding, damage to the City’s sewer pipes and other City infrastructure, and impact the water quality in Lake Ontario, local streams and rivers.

    The Sewers Bylaw sets strict limits on what can be released into sanitary sewers, storm sewers and our local waterways.
