Every day hundreds of millions of people scavenge to meet their daily water needs. While the iconic image of this hardship are women carrying jerry cans in Africa, there's a side of the water crisis you don't often see unless you visit both urban and rural regions around the world.

In many places, including India and Haiti, public and private services deliver water through a patchwork network of trucks - or water lorries as they are known in south Asia. This is done for a variety of reasons most notably lack of urban piped infrastructure but also include low water tables or natural disasters like drought or earthquakes like we saw in Haiti.

On a visit a few weeks ago we had the opportunity to quickly interview one of the drivers of a water lorry from India. What he told us will show you a side of the water crisis you've never seen.
