Second Narrows Water Supply Tunnel - Cathodic Protection

The proposed project 

Metro Vancouver is planning to 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.
