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.
