Abstract
The purpose of this study is to develop an evaluation method on the fire protection capacity of water distribution system from the viewpoint of business continuity. In this study, an evaluation model based on disaster resilience curve, which could describe disaster mitigation and resilience in water service, was developed. The distribution network analysis including emergence of the fire extinguishing quantity of water was carried out, the number of node availableas as fire hydrant was calculated in accordance with the requirements of hydraulic pressure at nodes. The fire protection capacity of the water distribution system in the emergency restoration period for the actual distribution network of the Kobe City was evaluated with the numerical evaluation model. Then, an evaluation procedure on the fire protection capacity of water supply distribution system based on disaster resilience curve was proposed. As a result, it was pointed out that disaster prevention for reliable water supply system would require not only mitigation but also resilience.
