Toronto's sewer system is designed to handle most storms, but not severe storms. However, due to recent climate change, storms are getting more intense and frequent. As a result, the system can become overloaded, flooding streets and creating ponds in low-lying areas. The City is working continually to improve the sewer system in chronic basement flooding areas. Homeowners can also take steps to help prevent their basements from flooding:

  • Ensure the ground is sloping away from your home's foundation
  • Fix leaks in your basement and around windows
  • Seal window wells
  • Clear eavestroughs and downspouts of debris
  • Disconnect downspouts that empty into the sewer system, making sure they drain at last 18 metres/6 feet from your basement walls
  • Install soft-surface landscaping (shrubs, porous paving)
  • Insert sewer connection backwater valves
  • Install a basement sump pump
  • Avoid pouring grease into your drains
