Comox Valley Water Treatment Project

The Comox Valley Water System provides drinking water to 45,000 residents but doesn’t comply with current provincial guidelines.

A new system is needed to bring our water treatment in line with other communities across BC, Canada and the developed world.

Project Timeline

Construction of the new water treatment system is scheduled to begin late in 2019 and will be fully operational by 2021.

Project Cost

The cost of the new water treatment system is estimated at $110 million. While at least 74 per cent will be paid by reserves and grant funding, the Comox Valley Regional District (CVRD) must borrow up to $29 million to pay for the remaining share of costs of the project.

Who Pays

Only those connected to the Comox Valley Water System will be responsible for paying for the project, at an average cost estimated at $86 per household per year.

Boil Water Notices

The Comox Valley Regional district has installed temporary UV treatment which is expected to reduce boil water notices by about 80 per cent until construction is complete.

Once the new system is up and running turbidity related boil water notices will be eliminated altogether.

  • Why are motorized boats allowed on our drinking water reserve, Comox Lake?

    Katy asked 22 days ago

    Hi Katy - the CVRD does not own the land around Comox Lake, nor the lake itself - this means we do not have authority over motorized watercraft use. We must work together with all stakeholders in the watershed to balance interests such as recreation, private ownership, traditional use, active logging, and hydroelectric power generation, while providing drinking water and sustaining critical fish and wildlife habitat. 

    The Comox Lake Watershed Protection Plan was developed to guide the management of the Comox Lake Watershed for the long-term protection of drinking water at the highest possible quality. You can learn more on this site's Connected by Water page over at www.connectcvrd.ca/connectedbywater or by visiting www.comoxvalleyrd.ca/watershed.

  • I’ve been reading about a company, Sharc Energy, that has been converting sewage into energy. Has this company been considered as part of the sewage/wastewater for the valley?

    Will asked 5 months ago

    Hello Will - Heat recovery from wastewater has successfully been implemented at several BC locations, and is one of the long listed options for resource recovery in the planning process now underway for the Comox Valley sewer service (we have a ConnectCVRD page for that project too - over at connectcvrd.ca/lwmp). At this stage of the process, the team will look at the size of the available resource (in this case heat) and at where it could feasibly be used.Those resource recovery options that look the most promising will be shortlisted for further study, which includes consideration of various technologies and technology providers. The simplest example of a potential use for recovered heat is for the space heating demands at the treatment plant itself, and this is being looked into.
    We hope you'll share your input over at the Help Shape the Future of our Sewer Service page moving forward, if this remains of interest.
