Water is the soul of all living things it is the most and top of any other needs, Apart from this requirement in this world industrialization going on rapidly such as Pharma, food, textiles, Chemicals, Motor, Vehicle etc when these industries are leaving their effluent untreated directly in to water bodies it is the main root cause of major water pollution Common contaminant of water has been classified into physical, chemical and biological sources. Physical sources are turbidity, color, odour and other floating matter. Chemical sources comprises of Biochemical oxygen demand (BOD), Chemical oxygen demand (COD), chlorides, alkalinity, pH, hardness etc. biological source of contaminants are the coliform bacteria and pathogens causing gastrointestinal disorders in all of these industries water is playing important role no Industries can run without source of water so water consumption from different sources are day by day increasing by the side water exploitation also increasing by so many activities. The main reason that can be mentioned here is water management is not right enough to accept. When the waste water is managed appropriately with the applications of recent technology it is possible to reduce waste water creation also to reuse the waste water produced. Water is the basic thing that must be available for the existence and evolution of all living organism but nowadays the quality as well as the quantity of drinking water is deteriorates to major level of polluting sources due to mismanagement of government in saving water during the rainy season and treating waste water by the industrial activities as well as domestic people activities.
