oa Civil Engineering = Siviele Ingenieurswese - Aqueduct to link Central Africa with Southern Africa? A brief outline
it is generally accepted that at some time in the comparatively near future - say between 2025 and 2055 - it will be necessary to supplement the water supplies of the Republic of South Africa, as well as those of some other water-scarce countries in the SADC region. As it would typically take 30 to 40 years to bring a major international water transfer scheme to fruition, it is not too early to start looking at various possibilities. The authors suggest that the rivers of Central Africa could possibly serve as one of the future sources for water supplies for the dryer south. If a scheme to transfer water from the water-rich rivers of Central Africa southwards to Botswana, Namibia, Zambia, Angola, Zimbabwe and South Africa were to be tackled on a sufficiently large scale, considerable royalties could be generated for the benefit of the northern-lying countries.
