The objectives of the study is to add the disaster prevention function to the present sewage systems. It was proved from the late Hanshin Great Earthquake that all kinds of water, i.e., drinking water, toilet flushing water, and fire extinguishing water, was depleted in the disaster. Sewage systems are networks of pipelines and treatment facilities in the middle of urban area. It can work as a source of water and provide a refuge to the urban population. A simulation study on water management in an earthquake was carried out in Adachi word of Tokyo using GIS systems. The result of the simulation showed that some parts in this word may lack sufficient water to distinguish fires and later sanitary use. These waters may be supplemented by wastewater treated by appropriate methods. Experimental studies on wastewater treatment with immobilized bacteria showed that it can be used a s a rapid treatment methods to create non-contact water, while membrane treatment can provide high quality water which can be used for sanitary and any other purposes except for drinking water.

这项研究的目的是在现有的污水系统中增加防灾功能。阪神大地震后期的事实证明，在这场灾难中，饮用水、冲厕水和灭火水等各种用水都被耗尽了。污水处理系统是城市中心区的管网和污水处理设施。它可以作为水源，为城市人口提供避难所。利用地理信息系统对东京Adachi Word地震中的水资源管理进行了模拟研究。模拟的结果表明，这个世界上的一些地方可能缺乏足够的水来区分火灾和后来的卫生使用。这些水可以用经过适当方法处理的废水补充。用固定化细菌处理废水的实验研究表明，它可以用一种S式的快速处理方法产生非接触水，而膜法可以提供优质的水，可以用于卫生和除饮用水外的任何其他用途。
