Introduction

 * "Water does not resist. Water flows. When you plunge your hand into it, all you feel is a caress. Water is not a solid wall, it will not stop you. But water always goes where it wants to go, and nothing in the end can stand against it. Water is patient. Dripping water wears away a stone. Remember that, my child. Remember you are half water. If you can't go through an obstacle, go around it. Water does."

(Margret Atwood) Out of five elements in the earth creation, water holds its most significant place. We human being can make their survival on the earth. In Hindu Mythology water is "varuna". It is the universal solvent which is neither acidic nor basic.Water pollution is caused when we contaminate the water bodies by adding pollutants to it

Water borne diseases spread by contamination of drinking water systems with the urine and faeces of infected animal or people.Waterborne disease in both epidemic and endemic forms continues to occur in both developed and less developed countries. Waterborne diseases are dominated by pathogens which are transmitted by the faecal droplet inhalation (e.g. adenoviruses). It is also interconnected with the consumption of shellfish and other harvest fisheries outputs and through indirect exposure to water in foodstuffs when the water is used in irrigation, in food processing, or as an ingredient. It spread from person to person, consuming contaminated food or beverages, from contact with animals or their environment.

Infectious diseases cause approximately 26% of all deaths worldwide and 31% of all disability. Water plays a role in the transmission of a significant number of these diseases. In the last 20 years, it has been recognized that many diseases are caused by emerging or re-emerging pathogens, 75% of which are zoonotic. Approximately 4 billion cases of diarrhea occur each year, leading worldwide. The percentage of illness caused by pathogens is difficult to determine. Waterborne pathogens cause both gastrointestinal disease such as diarrhea and other illness such as leptospirosis and hepatitis.

Available evidence suggests that emerging waterborne pathogens will continue to be recognized as being of significant and increasing public health concern due to a range of underlying driving forces. This include: •Changing pattern of water use •Increasing travel and recreational activities •Water scarcity, climate change, severe weather events, •Conflicts and disasters •Increasing urbanization and colonization of new habitats •Density of domestic pets •Ecosystem disturbance

Water related diseases are the most common cause of deaths. The paucity of clean water for domestic use has led to the increase in the number of deaths in both the urban and rural parts of developing economies. And India is no different. Deaths due to water related diseases in India are in the range of nearly 80 percent. Here is a list of the 5 most deadly water related diseases that occur in India.

Today, 37.7 million Indians are affected by waterborne diseases annually, 1.5 million children are estimated to die of diarrhoea alone. Until the 10th Five Year Plan, Neither the State itself, nor in partnership with private players has made it a priority to deliver safe drinking water to the country’s 700 million rural population.

If waterborne diseases are eliminated, the sale of antibiotics will come down and pharmaceutical companies will lose revenue. But the flipside, to be ruthlessly businesslike, is that in the long run, a healthier population will fuel economic growth and with it their purchasing power.

Water-borne diseases and water-caused health problems are mostly due to inadequate and incompetent management of water resources. In the urban areas water gets contaminated in many different ways, some of the most common reasons being leaky water pipe joints in areas where the water pipe and sewage line pass close together. Sometimes the water gets polluted at source due to various reasons and mainly due to inflow of sewage into the source.
