Releasing chlorinated water into the natural environment

This information is for businesses and municipalities that as a planned activity or in an emergency, need to release chlorinated potable water into the natural environment.

The level of chlorine contained in tap water is harmless to humans. However, chlorine can impair the ability of fish and other aquatic organisms to breathe, making it toxic even at extremely low levels.

To address this environmental risk, Metro Vancouver has developed guidelines for managing releases of chlorinated tap water for various types of activities. 

If you are municipal staff or a contractor working on a municipal project, please contact Metro Vancouver at 604-432-6200.
