India has sufficient water storage and drinking and domestic water's crisis in never going to happen. I just visited, Narmada dam and I had a special privilege to go to under ground tunnel to see electricity plant and drive car over the dam. Dam is full of water with just 1 meter bellow overflow. They told me that even if a single drop of rain doesn't come, the water is sufficient to last for 3 years. Sardar sarovar has a huge catchment area stretching over 200 km from dam location. So water crisis is a past in most of the are of India. Extraordinary steps are being taken by Modi government to eradicate flood and water crisi for ever in the country.
Inspite of 3 to 4 bad monsoon , I get 24X7 water in my house.
