Can water ATMs solve India's water crisis?

In many rural communities in India, access to clean drinking water is still scarce. The cost of bottled water is prohibitive, city pipes are in poor condition, and the municipal tanker trucks that supply some water are haphazard. But a social business called Sarvajal is busy scaling up a solution: a water ATM. These machines allow people to scan a pre-paid card and withdraw purified water from a stable, convenient source within their community when needed.
