In Vancouver, rainwater runs off into our sewer system and can cause:
- Flooding
- Sewer overflows
To help reduce flooding and overflows, we:
- Need to look at ways to manage rainwater
- Are working with Metro Vancouver to improve the public sewer system
Private properties also have a role to play in keeping rainwater out of our sewers.
