The Berg River Dam is a 68 m high dam on the Berg river in South Africa. It is the centerpiece of the Berg Water Project (BWP) which is designed to capture the winter rainfall and store it for supply to Cape Town during the dry summer months.
The dam will increase the water storage capacity to supply Cape Town, South Africa's second largest metropolitan area, from 768 to 898 million cubic metres. The scheme will also improve the reliability of water supplies in the drought-prone river basin. It is also expected that it will contribute to improve the naturally poor water quality in the lower reaches of the river.
The Berg River Dam was the first dam in South Africa to be designed, constructed and operated in accordance with the guidelines of the World Commission on Dams.
The Concrete-faced rockfill dam is 62m high and 929m long. Its gross storage capacity is 130 million m³ and the surface area of the reservoir is 488ha.
