Is this idea impossible to implement, as claimed by successive Egyptian governments, whether during the era of Mubarak or after the Jan. 25 revolution? Egyptian Minister of Water Resources and Irrigation Mohammed Abdel Matlab answered this question. He told Al-Monitor that linking the Congo River to the Nile is difficult to implement because it requires a canal that goes through southern Sudan, which is riddled with ponds and swamps. Thus, the project would threaten to inundate its territories. What's more, there are some legal problems relating to the prohibition of transferring river waters outside their basins, which is an international principle that Egypt cannot risk violating, not to mention the very high cost of such a project.
