Abstract

In the emergency response to the lifeline damage in 1995 Kobe Earthquake Disaster and restoration works of these damage to lifeline facilities after the earthquake, the interconnection problems of lifelines were reported. Even now, almost 30 years after the Kobe earthquake case, similar problems will occur in case of an earthquake. However, the details of the interconnection problems may be different from the past cases. From this viewpoint, the member of Lifeline Network, Kansai (LiNK) examined the past damage and the current status of countermeasures. In this paper, the results of the study on the past damage and possible interconnection problems in future on sewers and waste disposal operations are summarized.
