The reliability of water supplies, electrical, gas and other infrastructure in event of an earthquake is critical to the prevention of post-earthquake fires.
Vancouver has a secondary salt water supply system covering priority areas of Vancouver for contingency purposes in the event that the primary potable/fire supply is damaged by a seismic event.
The California Building Code requires secondary water supply systems in high buildings; however, there is no provision in Canadian codes- even for seismically active zones.
