With a current rate of Rupee 5 for 20 litres of water, you can simply purchase a week's quota of clean drinking water for his family. All you needs is prepaid smart card, which works almost similar to a debit card, to obtain clean drinkable water out of 'water ATMs'.
Bangalore city has been struggling to cope up with depleting groundwater levels and additionally has also been trying to control water contamination of water coming directly out of the public bore wells. To take care of the issue and provide access to clean and affordable drinking water, water ATMs are being set up. These ATMs have been directly connected to public bore wells, which so far were not supply clean drinking water. By fitting water ATMs to these bore wells and connecting them all to a decentralised treatment plant, clean and drinkable water after reverse osmosis (ultra-filtration, nano-filtration and ozonisation) is being provided to local communities, villages and even hundreds of slums at a nominal cost of 5 rupees for 20 litres.
Users make use of a pre-paid smart card that has direct access to the water ATMs. With a single swipe of their card, they have a 24/7 access to this very essential commodity. Currently, setting up one water ATM costs around Rs. 5-12 lakh (10,000-20,000 USD) and these ATMs are being set up by private investors with partial support being provided from a city development fund alloted by local legislators.
