Analysis of domestic water consumption in typical countries and its enlightenment to China

With the development of the country and the improvement of the level of science and technology, the use of water resources in China is on the rise. Among them, the domestic water consumption is increasing rapidly, and it is predicted that the domestic water consumption in China will reach two to three times that in the early 21st century in the middle of the 21st century. Based on the data of domestic water consumption in ten typical countries in the world, such as the United States, Germany and Japan, this paper studies the variation of per capita domestic water consumption in these countries with per capita GDP, urbanization rate and other factors. Taking these data as samples, the domestic water consumption in China is predicted. The prediction results can further help relevant departments to formulate reasonable policies in water resources planning
