Need of the project

water consumption rate is doubling every 20 years, out spacing two times the rate of population growth.Out of the total water resources, 97% remains in oceans as salty water, 3% remains as ice and rest 0.6 to 1.0% remains as fresh water either on surface or as ground water. That is, the available fresh water resources are very limited. Majority of the fresh water is frozen in Antarctic and Greenland icecaps. Most of the remaining fresh water lies too deep underground to be accessible.

Existing water resources are diminishing due to following reasons1 Due to unequal distribution of rain water and alsopoor storage facility and careless attitude, carries a lot of rain water to oceans and seas.

2 Excessive exploitation of ground water sources and inefficient recharge. The ground water resources are declining due to overgrazing and deforestation which cause soil erosion and make the soil unable topermit water infiltration.

3Various industrial and development activities in recent times have resulted in increasing pollution level and deteriorating water quality. Many pollutants threaten water supplies, but the most widespread,especially in developing countries, is the discharge of raw sewage into natural waters; this method of sewage disposal is the most common method in underdeveloped countries. In addition to sewage, nonpoint source pollution such as agricultural runoff is a significant source of pollution in some parts of the world, along with urban stormwater runoff and chemical wastes dumped by industries and governments. Thus improper management of water and ignorance a lot of water is lost.

4 The degradation of vegetational cover in the hills and catchment areas, there is siltation of water bodies.

5The impact of increased use of water for irrigation is a decrease in the quality and quantity of downstream water, with implications on both ecosystem functioning and on downstream use for agriculture, industry and municipal supplies.

80 countries and almost 40% of worlds population face scarcity of water. 25% have inadequate supply ,both for quality and quantity. Use of unhealthy water causes 80% of diseases and 30% deaths in developing countries.
