A cost-benefit formulation for an existing water supply system is presented. The formulation takes into account the existing seismic risk and investment needed to reduce this risk to an acceptable level. The investment is made to replace the existing weak pipes to other types of pipes which have higher seismic resistance. The losses due to earthquake considered in this paper are restricted to those resulted from the damage to buried pipes (repair cost) and the malfunction of the water supply (emergency supply cost). Indirect losses such as fire, inconvenience and so on are not considered. The total expected cost, which is the sum of the investment and expected losses induced by earthquakes, is calculated for a given seismic environment. Several example calculations are performed by introducing simplifications and assumptions in damage and loss functions, and the sensitivities of the parameters are examined. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
