Water Resource of India Sr.no. Source km3 /mm3 1 Annual precipitation including snowfall. 4000 Km3 2 Runoff/ surface water 1869km3 3 Utilizable surface water 690.4 km3 4 Ground water 431.4 Km3 5 Total utilizable ( surface & ground water) 1121.7km3

Some facts about India 1.India roughly accounts for about 2.5 per cent of landmass. 2.16 per cent of world population. 3. 4.5 per cent fresh water resources. 4.Due to increase in population, the total annual renewable fresh water available is being reduced from 5,177 cum(1951) to 1,342 9(2000) cum per person.

Causes of drinking water problem in India Major causes; 1.Population explosion 2.Pollution 3. Migration 4. Climate change

Provision of Drinking Water in Constitution of India Sr.No. Article provision 1. 21 Protection of life.. 2. 47 Duty of the state to raise the level of nutrition and standard of living and to improve public health 3. 243 G(11) Drinking water 4. 243 W(5) Water supply for domestic ; industrial & Commercial purpose

National water policy of India (1987, 2002 & 2012) Water allocation priorities to be broadly as below; 1. Drinking water 2. Irrigation 3. Hydropower 4. Navigation 5. Industrial & other uses
