Comox Valley Sewer Conveyance Project

Preparatory Work: Archaeological Investigations Beginning Nov. 28

Starting November 28, and lasting three to four weeks, the CVRD will be completing borehole drilling along the route to confirm the presence or absence of archaeological materials.

WHAT? The archaeological investigations will include drilling of roughly 135 boreholes in eight sections along the conveyance route.

WHERE? Test drilling will be completed along Comox Road (including Comox Hill), Beaufort Avenue and small sections of Stewart Street, Balmoral Avenue and Jane Place.

HOW? Work will be completed section-by-section, so only one area will be disrupted at a time. Single-lane alternating traffic will be required to make room for equipment.

The following schedule approximates the days and sections that will be investigated:

  • Week 1: Tuesday, November 29 to Saturday, December 3 - Beaufort Avenue from Carthew to Stewart Street (Section 5), start on Stewart Street between Beaufort Street and Comox Avenue (Section 6).
  • Week 2: Monday, December 5 to Saturday, December 10 – Complete Stewart Street (Section 6), Balmoral Avenue between Pritchard and Torrence Roads (Section 7), and Jane Place from Comox Pump Station to Beaufort Avenue (Section 8).
  • Week 3: Monday, December 12 to Saturday, December 17 –Comox Road from the Courtenay Pump Station to the Dyke Road Park, near 3035 Comox Road east toward Bayside Road, and near Bayside Road to Glacier View Drive (Sections 1 - 4).
  • Week 4: If necessary to complete all drilling work.

Protecting our ocean with a new route for sewer pipes

The Comox Valley Sewer Conveyance Project is a multi-year construction project that will replace the pipes and upgrade the pump stations that move more than 14,000 cubic metres of raw sewage each day to the sewage treatment plant on Brent Road.

This new system will route sewer pipes further inland where they will no longer be vulnerable to damage by waves, rocks and logs. Watch this video to find out more about the project and how it will protect the beaches and waters throughout the Comox Estuary, Point Holmes, Goose Spit coastline, as well as Baynes Sound.


About the Project

This is a significant and complex Project that starts at the Courtenay Pump Station and moves through K’ómoks land, downtown Comox and the Lazo Road area to the Comox Valley Water Pollution Control Centre (Sewage Treatment Plant) on Brent Road. There are construction impacts, traffic impacts and archaeological considerations. The CVRD is working with many jurisdictions and partners to deliver this project smoothly and efficiently and minimize impacts where we can.

  • Prep Work for Sewer Project Begins

    supporting image

    Starting on November 28 and lasting three to four weeks, there will be borehole drilling along sections of Comox Road and partial sections of roadways in the Town of Comox. This work will reduce roadways to single-lane alternating traffic during the week from Monday to Saturday.

    The project team is completing this preparatory archaeological investigation work to better understand ground conditions, and find out whether there are any culturally sensitive materials within the project footprint.

    To find out more details about traffic impacts and the sections to be investigated, read the backgrounder here.

  • How We Selected the Route For the Sewer Conveyance Project

    In 2018, the CVRD started work on a Liquid Waste Management Plan (LWMP) for the Comox Valley Sewer System to ensure our system will continue to operate safely and grow with our community. The LWMP identified a preferred conveyance route for new/upgraded sewer pipes and pump stations, which was approved by the Comox Valley Sewage Commission in February 2021.

    The final project scope was confirmed after six months of further review/assessment, which was completed after the successful Alternate Approval Process in summer 2021. This additional assessment led to some updates from the original route presented, including:

    • Cut-and-cover (trenching) at Comox Hill: The traditional trenching method has been selected rather than tunneling. This will reduce risk while meeting long-term operational goals.
    • New Courtenay Pump Station: A new pump station would be more cost efficient in the long-term and allow the CVRD to move it away from the K’ómoks Estuary, reducing operational and environmental risk.
    • Gravity line tunneled at Lazo Hill: The pipe route will still be tunneled at Lazo Hill, and the final route selected allows a gravity flow – reducing the already-very low risk of a leak and reducing ongoing operational costs.

    The approved scope allowed the project to move into the final design and tendering stages.

    To learn more about how the chosen route was selected, visit the LWMP website and click the Public Engagement and the Key Milestones Report drop-down menu.

    In November, the CVRD shared a project update with the community – preparing residents for construction starting next summer and providing more detailed information on construction impacts and costs.

  • What We Heard: Planning for Traffic Impacts

    supporting image

    In June/July 2022, we asked stakeholders, community groups and service providers for input on traffic management planning during the Comox Valley Sewer Conveyance Project. The project will provide a critical update to sewer infrastructure that will remove an urgent environmental risk – but we recognize it will also be highly disruptive along an already-busy traffic corridor and are committed to engaging with the community to reduce impacts where possible.

    The feedback provided has helped the project team better understand how the area along Comox Road, Comox Hill and routes in/through downtown Comox are currently used, what management measures would be most helpful and what the biggest concerns are about disruption. Thank you to everyone who took the time to provide input – the feedback will inform the traffic management strategy which will be shared with the community later this fall.

    The summary report about this community engagement is now available here.

    Watch for more information soon about community information sessions in November, that will provide updates about construction planning and the traffic management strategy to be implemented.
