The Lesotho Highlands Water Project is a multi-phase binational project carried out by the Kingdom of Lesotho together with the Republic of South Africa.
This hydraulic dam project, located in the Provence-Alpes-Côte d'Azur region (PACA), included design consideration for the control valve’s rotational axis deformation, maximum stress, and material fatigue behavior.
The sluice gate is based on a pressure segment used to control the water level of the weir. The flap width is 23 ft, the total width of the structure is 34 ft. It is possible to dam water to a maximum height of 18 ft. The structure is made of S 355 steel.
