Description

The share of domestic water within the global water demand is small, yet as it is a basic requirement for human life, it remains absolutely necessary for the sustainability of society. However, due to population growth, urbanization, and changes in life style, demand for domestic water rises drastically, leading to grave concern over water shortage.<BR>This study utilized panel data analysis aiming to develop a global country-wise domestic water demand estimation model. In addition to the connection between income and water demand, the study strove to develop a distinct model that would separate the effects of income and non-economic factors, such as political/social circumstances, lifestyle including specific cultural backgrounds, which were not considered in prior research. As a result, the study succeeded in formularizing: (1) accessibility to tap water, (2) tap water demand by country, and furthermore (3) the amount of water leakage, which poses a problem for the maintenance of water supply facilities.
