The ever-increasing demand for water to satisfy both urban and agricultural needs in the Western Cape was forecast to exceed available supplies within the foreseeable future. A comprehensive study was required to plan the development of schemes to meet this need in a structured fashion. The prior development of systems modelling techniques for the Vaal River System provided an opportunity to apply this methodology also to the complex water supply system of the Western Cape. This would permit the four main water supply nodes to be evaluated in a single system, rather than separately, and advantage to be taken of the different rainfall characteristics of the catchment areas draining to the main dams.
