Water is a basic and primary need of all vital processes and it is now well established that the life first arose in aquatic environment. Ever since the pre-historic times man has been intimately associated with water and it has been continuously proved by the evidences of past civilization that all historic human settlements were around inland fresh water resources. The Republic of India rightly perceived the conclusions drawn by the International Environmental Conference (1973) and focused the attention of entire scientific community on the non-availability of good quality of water in sufficient quantities and the problems of the management. The fast depleting of water resources are adversely affecting the terrestrial life and pushing posterity towards disaster.
