In 1957, in response to a request from the Northern Cape Regional Development Association, Mr Shand proposed a revolutionary concept to put the hitherto little used water of the Orange River to beneficial use. Because the Orange River runs in a deeply incised valley, the Department of Water Affairs had concentrated on the idea of tunnelling through to the Fish River, to enable Orange River water to be supplied to the Eastern Cape. Mr Shand's idea was to lift the water out of the valley by means of a very high dam at Vanderkloof, and, there being no national electricity grid at that time, to use the energy of water released down the river channel for irrigators along the Lower Orange to pump the remaining water to levels high enough to command the surrounding plateaux.
