Water ATMs bring clean water to Delhi
The authorities in the Indian city of Delhi are piloting a scheme to bring clean drinking water to the city's residents.
Known locally as water ATMs, the water dispensers use pre-paid smart cards and allow people to fill containers with water for a small fee.
The pilot has proved so successful that the city government is now looking to expand it.
