Projection of domestic water use influenced by the water related appliances in Tokyo
In this study, the amount of the domestic water use was quantified by estimating the usage rates of the water related appliances. Tokyo was selected as a case study. From a result, the calculated amount of domestic water use corresponded to the actual amount of that from 1998 to 2006 and the reduction rate is assumed to be 8% until 2025 and 10% until 2050 when the 1997 was set to be a base year according to the newly proposed model. In addition, it was considered that the water use for bath and toilet is expected to be large even in the future in Japan according to the present trend of the usage rate.
