Water researchers probe for answers

Kabwe is a transport hub and old mining town in central Zambia. One resident, Joseph, recounted how when he was growing up in the town in the 1970s, most houses had a tap and a reliable water supply from the municipal system. Few children in the town now have this luxury; in the 1980s the world price of copper collapsed and the mines closed.

Many of the townspeople could no longer afford their water bills, and the lack of investment led the municipal water system into a spiral of decline.
