Abstract

 The results of forecasting domestic water demand in the long term are important for planning wa-ter supply facilities and operation and management systems. In Japan, recently, domestic water de-mand has been decreasing because of the progress of a water saving society such as spread of water-saving equipment. With the spread of various types of water use equipment and the diversification of lifestyles, it is required to forecast the future water demand at the household level when forecasting water demand. In this study, WEB questionnaire survey was conducted to grasp the latest water usage. And, long time changes of water demand structure was analyzed by questionnaire surveys which were conducted over three periods.  As a result, the unit water consumption decreased over time. In addition, water use behaviors such as the frequency of laundry and water saving behavior directly affected the unit water consumption, but the magnitude of the effect changed over time.
