Water Quality and Treatment

Drinking water is treated to meet current drinking water quality regulations; a new filtration process will be required in the future to supplement the existing disinfection processes, particularly when water from the Goldstream and Leech water sources are used to supplement supply. The addition of filtration in combination with existing disinfection processes (ultraviolet disinfection followed by the addition of chlorine and ammonia) would provide a robust multi-barrier system able to better mitigate potential adverse raw water quality due to climate change impacts, reduce the vulnerability of the current treatment system, and protect public health.
