Abstract
In this paper a method to install dedicated water supply system for firefighting is proposed in order to maintain firefighting water in an emergency like earthquakes. At first, the method to determine the fire hazard area and to estimate water volume required for fire extinguishing is proposed. Analyses on fire damage during the Kobe earthquake are used in this method. Furthermore, the water supply system is designed using water flow analysis considering hydraulic reliability and cost. An application to Kobe City is shown as an example at last.
