Zambia and Zimbabwe will give French engineering firm Razel-Bec the task of repairing Kariba Dam. The dam's walls are swelling, raising the risk of cracks in the structure that holds back up to 180 billion cubic metres of water. A collapse of the dam wall could pose a risk to millions of people in Zambia and Zimbabwe -- as well as Malawi and Mozambique further downstream. The dam was built in the 1950s. According to its safety manager, the expansion should be completed by the end of 2020, while work on the spillway to contain the swelling is expected to be done by 2022.
