The 'water ATM' can process 1,000 litres in an hour

As dawn breaks, two queues start forming at the only petrol pump in Lakshmangarh, a small town in Rajasthan’s Alwar district. One, obviously, is of people waiting to get their vehicles’ fuel tanks refilled. The other is in front of a simple metal box mounted on the petrol pump’s boundary wall. People like to call it an ATM machine. But, instead of dispensing cash, it gives them clean drinking water.
