Trucking water to Uganda's refugee camps

Hundreds of thousands of South Sudanese refugees have fled violence and hunger in their home country for the safety of camps in northern Uganda. More than 50,000 of them now live in Rhino camp, a sprawling expanse of huts and tents scattered across dusty scrubland near the town of Arua.

Life in the camp is tough, but everyone seems to agree that one of the main challenges is water. There are no boreholes, and the few streams that flow through the area are often completely dry. When they're not, the water runs a deep chocolate brown.
