The Highlands hydraulic project, in Lesotho

The concrete structures of French companies allow water to be brought to South Africa and electricity to Lesotho. In South Africa, French companies have built a dam and tunnels to take water to South Africa, which is severely lacking in the resource, and to produce electricity, mainly for Lesotho.

Project Management: Lesotho Highlands Development Authority
Construction: Spie (pilot), Campenon Bernard-SGE (Vinci), LTA ltd, Balfour Beatty, Züblin
In the great spaces of Lesotho, a dam, tunnels and an underground plant appear to have fallen from the sky.

•The project is designed to increase the water reserves of the dam on the River Vaal to contribute to the development of the Guateng region in South Africa and to produce electricity for Lesotho.
•For this, two main tunnels of 45 and 13 kilometres in length, and of 5 metres in diameter have been excavated.
•A double curvature arch dam has been built.
•A massive underground plant has been constructed.
