Metro Vancouver | Second Narrows Water Supply Tunnel – Cathodic Protection
On December 2, 2022, a project permit was issued to Metro Vancouver to develop Second Narrows Water Supply Tunnel – Cathodic Protection located approximately 450 metres east of Second Narrows Bridge on the North Shore of Burrard Inlet, British Columbia on federal lands and waters managed by the Vancouver Fraser Port Authority.
The project was approved subject to 28 permit conditions the applicant must meet to ensure the project does not result in significant adverse environmental effects.
About the project
Metro Vancouver will install a cathodic protection system for the protection of Second Narrows Water Supply Pipelines. The project includes the installation of the cathodic system, which requires:
- Trenching a teck cable upland (outside port authority jurisdiction) and laying approximately ten metres of teck cable on the sea floor (within port authority jurisdiction)
- Installing an anode bed array, consisting of four tubular mixed metal oxide anode assemblies.
- Connecting the teck cable to the anode array bed
- Installing anchor chains to secure the anode array bed
The project is anticipated to be completed by January 2023.
