Water resources are critical for economic growth, and essential for ecology. In India, water resources are under tremendous pressure. Water demand is continuously rising, and with high population growth, the per capita water availability is decreasing over time. It is likely to touch the water scarce situation (about 1000 cubic meter per capita) in the coming years. The total water demand in India is projected to increase from 813 BCM (Billion Cubic Meters) in 2010 to 1093 BCM in 2025, and further to 1447 BCM in 2050 (TERI, Sept 2024).

By 2050, the expected water demand is likely to exceed the water availability. Of these demands, industry water demand is estimated as 17 BCM in 2010, 38 BCM in 2025........
