Disconnect and Extend Downspouts

Disconnect downspouts from municipal drainage systems and extend downspouts and sump discharge pipes at least 2m from foundation or to the nearest drainage swale.

  • Make sure that the end of your downspouts should drain at least 2m (5-feet) away from your home. 

  • Point the downspout towards a lawn, garden, road, or driveway. 

Do NOT: 

IMPORTANT: If your home was built before 1969, your downspout might run directly into your sanitary sewer system. During a stormwater event, these downspouts could overwhelm the sanitary sewer system and cause a backflow of sewage into your home or a neighbour's home.
