So according to Zhao, Liu, and Deng (2005), agriculture exploits almost 70 percent of freshwater available in China, and there is an expectation that this quantity will grow because of the increase of world food production. Chinese people need a comprehensive scientific approach with long-term, coordinated efforts to solve this serious problem. So the first possible solution is recycling water in order to meet environmental needs, provide an additional source of water and have sustainable development and a viable economy. For this approach the Chinese Government needs advanced technologies that clean the water properly and also huge investment, so this would lead to having a big impact on economic development of the country. However, according to Chang (2009), the water which has been recycled is an essential resource of water for “non-potable”(not for drinking) uses in China and this water can be used for flushing toilets, car washing, agricultural irrigation, fire fighting, landscape irrigation, industrial processes and street washing. But one major disadvantage of this approach is that after water recycling there is no proof of that this water is clean enough for reusing it. For example, there might be quite an amount of pollutants, such as some chemicals, bacteria, even heavy metals and organic compounds (Wang, 1989). So as consequences, there
Synopsis: Water is an essential ingredient of all kind of life. Earth is a unique living planet because eat has water. There is water and water and yet not enough to drink and May towns, cities and villages often face acute shortage of water. To alleviate the drinking water situation a mission was started in 1986 but man of the schemes under the project remain non-functional and thousands of localities use contaminated water. Maintenance and operation of water mission is a main problem to be solved. Another major problem to be tackled is water harvesting. India is one of the wettest counties of the world but the water harvesting is very poor. Experts say that traditional and local water harvesting is very purr. Experts say that traditional and local water harvesting system should be revived and encouraged as in that lays the water wisdom.
Water is one of the essential ingredients of life.

There is often scarcity of drinking water. There are droughts and famines causing untold misery, death and destruction. Today there are thousands of villages and towns acing an acute drinking water-shortage. Even in cities item huge water-supply plants there is not sufficient water and their supply is often limited to a very short period of the day… With the rapidly increasing pressure of population on our water resources, more and more villages, towns and cities are facing the problem. The then Prime Minister Rajiv Gandhi had to launch a dirking water mission and programmed in 1986 to meet the drinking water requirements. Then drinking water was available to only 30 per cent of the country’s population and today theoretically it is available to 91 per cent.

On the other hand, Jaywalker in Rajasthan has just about 100 mm of annual rainfall and yet this desert town was able to collect enough water for its use. But it too has started facing the drinking water shortages of late since government water supply system has begun bass on tapping of limited ground water neglecting traditional wisdom of water.
