As a result of this development, water closets in larger towns were to a larger extent connected to storm sewers. On the other hand, the handling of one problem led to the introduction of another one: surface water pollution. A receiving water body will up to a certain level be able to render harmless the contaminants of discharged wastewater through dilution. Nevertheless, when the quantities of pollutants exceed the recipients critical level, they will possibly do harm to the surroundings. In densely populated areas this is much likely to happen. The solution to this problem is through treatment of the raw wastewater. During the late 19th and the early 20th century, there was an awakening in the development of centralized wastewater treatment systems, mainly in the United Kingdom and the United 4 States. As an addition to collection and discharge of wastewater, physical, biological and chemical processes for the wastewater treatment were introduced, for the removal of pollutants.

The rapid growth of industries has not only enhanced the productivity but this also resulted in the production and release of toxic substances into the atmosphere, creating health hazards and effected normal operations, flora and fauna. Dairy industries are of critical importance to India. India is “The Oyster” of the global dairy industry. It offers opportunities galore to entrepreneurs worldwide, who wish to capitalize on one of the world’s largest and fastest growing markets for milk and milk products. This country is the world’s largest milk producer, accounting for more than 13% of world’s total milk, consuming it’s almost 100% of its own milk production. Dairies are centres where raw milk is processed either for immediate consumption or converted into other dairy products such as cheese, butter, whey etc. India’s dairy sector is expected to triple its production in the next 10 years in view of expanding potential for export to Europe and the west. Moreover with WTO regulations expected to come into force in coming years all the developed countries which are among big exporters today would have to withdraw the support and subsidy to their domestic milk products
