Abstract
1994 drought caused serious shortage of water, which had great influence on social activities as wellas water supply. The objectives of this study are to estimate the influence of the shortage of water onthe safety factor of water utilization using data of supplied water obtained during the drought period in1994, and to clarify the relationship between the consciousness of water consumers about waterutilization and water saving from results of questionnaire surveys. As a result, it was shown that theexperiences of past drought were not reflected in 1994 drought, which caused long-term shortage ofwater. And it was proved that a new appropriate strategy against shortage of water had to beestablished immediately. In addition, it was cleared that a strategy for enlightenment was alsonecessary, because of the insufficient understanding for shortage water which was shown in theinsignificant relationship between the consciousness of water consumers about water utilization andwater saving. In the result, some available knowledge for the safety factor of water utilization againstthe shortage of water were obtained
