Water Use

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.
