People in developed countries usually get their drinking water from a faucet(水龙头) or a bottle. But finding safe drinking water can be rather d     in developing countries. People in India, for example, often drink polluted water, which can lead to illness or even d     . But one Indian company, Sarvajal, has i     a great machine: the “water ATM”. Sarvajal’s water filtering(水过滤) network has already p   clean water in more than 130 places. Many of these places are small v    . The water ATM is new and important part of Sarvajal’s business.
How do these water ATMs w     ? First, local workers filter water using Sarvajal’s equipment(设备). Then workers s      the clean water to the ATMS and sell prepaid(预付款) cards to local people. Then they can e     get water form the ATMs with the cards.
Thanks to Sarvajal’s network and water ATMs, clean water is now a     to over 70,000 people in India. It makes sense that in one of the local l      Sarvajal means “water for all”.
