n Civil Engineering = Siviele Ingenieurswese - Water resource development in the Koonap River Valley, Eastern Cape : water engineering




Consideration of the feasibility of developing the water resource within the Koonap River Valley is not new. Records of investigations into development of the water resource within this area date back to the 1960s, driven by demands from farmers within the valley for greater reliability of irrigation water to develop agriculture. Boreholes located on the proposed Foxwood Dam site outside Adelaide date back to 1962, and a comprehensive agro-economic study was carried out in 1988. However, the proposed scheme never materialised due to insufficient commitment from farmers to develop the required land to make the scheme viable. Further studies of a large-scale dam development were carried out in the 1990s, prompted by renewed farmer interest in reliable irrigation water supply and concern over domestic water supply vulnerability during extended drought periods. However, no significant scheme has yet been developed.
