The relationship between per capita municipal water use (PCMWU) and gross domestic product (PCGDP) (purchasing power parity, constant 2011 US$) is statistically analysed for each country in the world. results indicate that PCMWU will increase with rising PCGDP at beginning, which then decrease when reaches a certain level. This trend follows rules of Water Use Kuznets Curve, an inverted U-shape curve describes (GDP). unbalanced panel data analysis world 183 countries 22 developed revealed peak point Municipal Curve (MWUKC) approximately US$33,000. specific reason MWUKC saturation demand. At same time, driving forces include technological advancements, growth prices, effective environmental regulations policies, water-saving consciousness. Most these mechanisms benefit from economic development. experiences provide guidance positive indicators developing or increasing PCMWU. Due to accelerated countries, could reach turning more rapidly.
