ORANGE–SENQU RIVER BASIN, South Africa
Of all water demand on the Orange–Senqu system in 2010, about 93% came from South Africa, of which 70% was from the irrigation sector. Historically and currently, the Orange–Senqu and its tributary Vaal system has provided the source of water, minerals and energy on which economic development has been based.
Water supply required to meet demands of the Witwatersrand economic hub and those of large-scale irrigation schemes further downstream has been assured through the construction of numerous dams and a series of transfer schemes, mostly on the upper Orange–Senqu and Vaal river systems. It is consequently regarded as the most developed river system in southern Africa.
