Chapter 2 Water Condition
China has still economically developed and the population has grown over
1.3 billion. However, with regard to water, there is only 1/4 water of
According to an estimation, the population in China will grow to 1.6 billion
by 2030. As the result, the water resource for one person decrease to １７６０㎥,
and it will reach to １７００㎥ which is the international indication for lack
of water. In many large cities of China, lack of water has already emerged.
When it sees at the city which has more than one million population, 30
large cities out of 32 large cities suffers from lack of water. Especially,
lack fo water is the most serious in Beijing.
In dry areas located in North, due to evaporation from water surface or overtaking of underground water, lack of water problem becomes more serious issue. On the other hand, South where provide lots of water, water contamination in rivers, lakes, and marshes became serious problem so that there is less water which people can use. Consequently, even rich water area such as delta area where has Chang Jiang and Zhu Jiang has issue of lack of water.

Water issue in China where has been regarded as world industry or kitchen
is the problem for not only China but also the world.
In Japan Water Guard, as the measure toward world water issue, we carried
out water purification project for China contaminated water environment.
