WATER SUPPLY ENGINEERING



The five most essential elements for the existence of human life are air, water,food, heat and light, of which next to air, water is the most important requirement for the human life to exist. In fact water is essential not only for human life but also for animals, plants and all other living beings. The importance of water for the living beings may be judged from the fact that it is a part of life itself, since the protoplasm of most living cells contains about 80 per cent water, and any substantial reduction in this percentage of water is disastrous. 

Most of the biochemical reactions that occur in the metabolism and growth of living cells involve water, and all take place in water, which has often been referred to as the universal solvent. Further it has been estimated that almost two-thirds of the human body is constituted of water which is required for the satisfactory performance of physiological organisms,as a circulatory fluid, as a carrier of nourishing food and for removal of the waste products from the body.

However, man uses water not only for drinking and culinary (i.e., pertaining to kitchen or cooking) purposes but also for bathing, washing, laundering, heating and air conditioning; for agriculture, stock raising (i.e., cattle breeding) and gardens; for industrial processes and cooling; for water power and steam power generation; for fire protection; for disposal of wastes; for fishing, swimming, boating, and other recreational purposes; for fish and wild life propagation; and for navigation.

It is thus evident that every activity of man involves some use of water. Moreover,the importance of water in human life is so much that the development of any city of the world has practically taken place near some source of water supply.
