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.

该研究的目标是将预防灾难的功能添加到当前的污水处理系统中。从已故的汉辛（Hanshin）大地震中证明，各种水，即饮用水，厕所冲水和灭火水，在灾难中耗尽。污水系统是市区中部的管道和治疗设施网络。它可以用作水源，并为城市人口提供避难所。使用GIS系统在东京的Adachi词中进行了关于地震中水管理的模拟研究。模拟的结果表明，这个词中的某些部分可能缺乏足够的水来区分火灾和后来的卫生用途。这些水可以用适当方法处理的废水补充。对用固定细菌进行废水处理的实验研究表明，它可以采用一种快速的治疗方法来产生非接触水，而膜处理可以提供高质量的水，可用于卫生和除饮用水以外的任何其他目的。
