Rainwater management on private property

What's happeningWhat's new: January 1, 2024

Simplified rainwater management requirements are in effect for new Part 3 (complex) buildings in Vancouver. Review the requirements for new development applications

In-stream development applications may be eligible to transition to the simplified requirements. Review information on transitioning in-stream applications.

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.
