Proposed New System and Location

Planned improvements to the Comox Valley Water Treatment System include:

  1. Deep-water intake to access cooler, cleaner water found deeper in the lake.
  2. Raw water pump station near the intake.
  3. Raw water pipeline from pump station to the treatment plant.
  4. Water Treatment Plant including filtration and disinfection.
  5. Treated water pipeline from the pant to the water distribution system.Water Treatment Plant  System Map


The new water treatment plant will use filtration, ultra-violet treatment and chlorination to remove bacteria, parasites and viruses from the water and eliminate the need for turbidity-related boil water notices.

As an interim measure to reduce the number of boil water notices until the treatment plant is built, the CVRD will install UV treatment at the existing chlorination facility which will be moved to the new plant once construction is complete.

These renderings demonstrate how the water treatment plant could look post construction.

Public Consultation

 Between November 2015 and fall 2016, three public workshops were held with community stakeholders to review options to provide improved water intake, compliant treatment and delivery of treated drinking water. Feedback received during the workshops has been incorporated into the current project parameters. For more information on the Comox Lake Water Treatment Options Study please click here.


The CVRD will once again be meeting with the community prior to the public assent in March 2018.  A series of public Information Sessions will be held in January and February 2018. Dates will be announced in early January.
