oa Civil Engineering = Siviele Ingenieurswese - Water demand and demand management



Using a variety of demand management techniques can lead to a significant delay in the implementation of additional water augmentation measures The success of water resource management, including planning and operational aspects, depends to a large degree on the ability to quantify two variables realistically: the yield capability of the water resource system and the projected future water demand. The estimates of future water demand can be influenced significantly by many factors, including population movements (or growth) and any initiatives of the Department of Water Affairs and Forestry (DWAF) to promote more efficient utilisation of water. Most of the analyses completed to date are based on demand projections that do not include any allowance for lower growth in demand owing to demand management measures that are likely to be implemented in the very near future.
