Canadian Rainwater Harvesting Rules

At the time of this post there are no across the board rules on Rainwater Harvesting in Canada! The Canadian National Plumbing Code also permits the collection of rainwater for non-potable uses such as toilet flushing and outdoor irrigation throughout Canada. 

However, a few provinces and individual municipalities have implemented their own set of guidelines that locals need to follow. These provinces are British Columbia, Alberta, and Ontario. 

When building a rainwater storage system, it is required that the design follows closely to the provincial codes and municipal bylaws. Again, these vary by province and municipality so be sure to do a little research before starting on your Rainwater journey!
