Comox Valley Sewer Conveyance Project

The Comox Valley Sewer Conveyance Project is an $82 million 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 Curtis Road.

This new system will route sewer pipes further inland where they will no longer be vulnerable to damage by waves, rocks and logs.

The project is the result of the extensive Comox Valley Sewer System Liquid Waste Management Plan (LWMP) which started in 2018, and was developed over three years with the input of a public and technical advisory committee. Construction of the new sewer line will start in Spring 2023.

    Part of a larger plan for sewer services in our community

    The CVRD shared its long term plan for sewer services including the final route for the Sewer Conveyance Project and future upgrades at the Sewage Treatment Plant with the community in April.

  • Project Scope and Route Approved by Sewage Commission

    On Feb. 22, 2022, the Comox Valley Sewage Commission approved the final project scope for the Comox Valley Sewer Conveyance Project. The approved scope will move the project into the final design and tendering stages.

    The scope was confirmed after 6 months of further review/assessment 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 tunnelling. 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 River, 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 community will be invited to updates – both in person and online – in early April to share more information about the final plan forward. Watch here for more information.

  • Video Recording: Comox Valley Sewer Conveyance Project Information Session, February 2, 2022

    Lazo Area residents were invited to join the Comox Valley Regional District last week for two webinar information sessions to update the community about the sewer pipe route and design through Lazo Hill, statutory right-of-way for impacted Lazo area properties, groundwater monitoring and a proposed groundwater protection policy for the Lazo area.

  • Planning underway for Sewer Conveyance Project

    supporting image

    With a conceptual pipe route approved by the Sewage Commission in February 2021 and borrowing approved in July – the project team is working now on the final route and project scope, to be ready this fall/winter.

    Read the press release about the successful Alternate Approval Process here.

    The CVRD remains focused on minimizing costs and impacts on residents and businesses and discussions are underway with the Town of Comox Discussions are underway with the Town of Comox regarding the final route through the Town and mitigating community impacts. The CVRD is also working with the K’ómoks First Nation to protect archaeologically sensitive areas during construction in an effort to preserve cultural heritage sites, ancestral burial places and artifacts.

    Watch this page for updates on time and details of our next public engagement events in fall/winter 2021-22.

  • Update on Sewer Conveyance Planning Shared with Lazo Residents

    Two online sessions were offered in May 2021, to inform local residents about ongoing sewer planning and to address questions about the tunneling feature of the selected pipe route. This update was the third in a series of sessions hosted specifically for Lazo Area residents and build on an 18-month Liquid Waste Management Plan process that included multiple stages of public engagement. This included Area B representation on a public advisory committee (PAC) which reviewed, discussed and provided recommendations at each stage of the planning process.

    Video of the session is posted at the ConnectCVRD LWMP page.

  • Tunneling and Groundwater Information Shared with Lazo Area Residents

    supporting image

    On March 4, the CVRD hosted a webinar for residents within the proposed tunneling area in Area B (Lazo area). The online session provided additional information about the groundwater monitoring and assessment work that has been completed to date, and the further planning that will be done before construction starts on the new sewer conveyance route, selected by the Sewage Commission in February. The project team responded to a number of questions from residents about potential impacts to their property, protection measures that are being planned, and other planning details.

    The information is now posted for anyone who was unable to attend:

    • Video of the session is now posted the at ConnectCVRD LWMP Page - you can find it in the videos section in the righthand menu or by clicking here.
    • While many questions were addressed during the 1.5 hour session, there were a few that required follow up. Those questions, along with the responses, are now posted in the FAQ section of the LWMP Connect CVRD page –in the right-hand menu bar as well or click here.

  • Preferred Conveyance Route Selected for Comox Valley Sewer Service

    On February 23, 2021, the Comox Valley Sewage Commission approved a plan to upgrade the pipes and pump stations that move wastewater from Courtenay, Comox and the K’ómoks First Nation to the sewage treatment plant.

    Key features of the selected option are:

    • A mix of tunneled sections (under Comox Ave. and Lazo hills) with traditional ‘cut-and-cover’ trenched installation. The tunneling will reduce the construction impact and operational pressure on the system.
    • Work to be undertaken as one phase, rather than separated into two phases divided by up to 15-20 years, to reduce risk posed by the estuary’s foreshore forcemain.

    The option is anticipated to cost $73 million, paid for by $21 million in reserves, and $52 million in long-term borrowing. The cost per household is estimated at $150/per year for 30 years. Read the press release here.
