Water Use

Water Use Water is a basic need for human society being required for drinking, bathing, washing, irrigation, industry, cooling, construction work, disposal of sewage and industrial effeuents. Agriculture consumes the maximum amount of water, some 70% of total. Industry requires 26% of water. Domestic and municipal consumption of water accounts for only 1.1%. Because of rising population, increasing urbanization, growing industrialization, rising standards of living, the demand for water is increasing day by day.
Water Availabilty : The basic source of water availability is rainfall. It occurs in India mostly during monsoon period which lasts for 3-5 months. For the rest of the year, there is no rain. The source of water availability shifts to ground and surface waters.
