A family in India needs fresh water. But this family can’t just turn on a tap. Instead, the women in the household must walk to fetch it, sometimes travelling miles carrying plastic or earthenware pots, possibly with a child or two in tow, to the nearest safe source – regularly repeating the journey up to three times a day. In the scorching summer months of April and May, when temperatures regularly exceed 40C, it is a particularly gruelling daily ritual – and when they get home they must complete their other household chores: cooking, washing, bringing up the children, even helping on the family farm.
