Sterkfontein Dam
The Sterkfontein Dam, located just outside the town of Harrismith, in the Free State, province of South Africa, is part of the Tugela-Vaal Water Project and the Drakensberg Pumped Storage Scheme, and located on the Nuwejaarspruit, a tributary of the Wilge River in the upper catchment area of the Vaal River. It is the second highest dam wall in South Africa and its highest earth fill dam. Background History The rapid economic expansion of the greater Johannesburg area in the 1960s and 70s put its water supply under long term threat and it was decided to redirect water from the large Tugela River which was going largely un-used into the sea and store it in large strategic water storage reservoir with very low evaporation. The initial site chosen for this project was in the adjacent valley to the west on the Elands River. This was the preferred option from an engineering aspect because it would involve a smaller dam wall. However shortly before construction was about to start t ...

Drakensberg Pumped Storage Scheme
The Drakensberg Pumped Storage Scheme is an energy storage facility built in the South African provinces of Free State and KwaZulu-Natal starting in 1974 and completed by 1981. Four dams are involved in the scheme; the Driekloof Dam (''joined to the Sterkfontein Dam''), the Kilburn Dam, the Woodstock Dam and the Driel Barrage. Electricity generation equipment is located between Driekloof Dam and Kilburn Dam. Since the Driekloof Dam/Sterkfontein Dam also forms part of the Tugela-Vaal Water Project some of the water pumped to Driekloof Dam might end up flowing to the Vaal Dam and not be available for return to the Kilburn Dam. The Woodstock Dam and Driel Barrage are used to supply this additional water to Kilburn Dam when required. The scheme provides for up to of electricity storage in the form of of water. The water is pumped to Driekloof during times of low national power consumption (generally over weekends) and released back into Kilburn through four turbine generators in ...

Dams Completed In 1979
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
