Pre-feasibility studies have shown that various transfer schemes are economically viable and technically feasible for supplying water to the Vaal River System. Orvaal Consult (a consortium consisting of Africon, V3 Consulting Engineers, Chunnett Fourie & Partners, Urban-Econ, Van Riet and Louw Landscape Architects and various other specialists such as the CSIR and HSRC) was appointed to evaluate options and to recommend the least-cost solution for the transfer of water from the Orange River in the vicinity of the Gariep Dam to the Vaal River System. This study, called the Orange-Vaal Transfer Scheme (OVTS), was one of the studies in the Vaal Augmentation Planning Study (VAPS). A complication was added to the study in that it also had to take cognizance of the fact that up to 40 m3/s of additional water could possibly be obtained from the Mzimvubu River.
