Grootdraai Dam
Grootdraai Dam is a combined gravity and earth-fill type dam located on the Vaal River, near Standerton, Mpumalanga, South Africa. It was established in 1981. Background Grootdraai Dam is a composite structure comprising a central concrete gravity section 360 m long and two earthfill flanks giving a total crest length of 2180 m and a maximum wall height of 42 m above lowest foundation level. The dam was completed in 1982 and was built primarily to support the water needs of the SASOL I, II and III coal to petrol plants at Secunda, Eskom's Tutuka Power Station as well as the Matla Power Station, Duvha Power Station, Kendal Power Station and Kriel Power Station located on the coal fields in the adjacent Olifants River basin. The dam also provides some flood attenuation for Standerton and stores up to 100 million m3/annum pumped into the upper reaches of the Vaal River basin from Heyshope Dam in the Usutu River basin.

Vaal River
The Vaal River ( ; Khoemana: ) is the largest tributary of the Orange River in South Africa. The river has its source near Breyten in Mpumalanga province, east of Johannesburg and about north of Ermelo and only about from the Indian Ocean. It then flows westwards to its conjunction with the Orange River southwest of Kimberley in the Northern Cape. It is long, and forms the border between Mpumalanga, Gauteng and North West Province on its north bank, and the Free State on its south. It is the third largest river in South Africa after the Orange River (2200 km long) and the Limpopo River (1750 km long) and was established as the main source of water for the great Witswatersrand area after the gold rush during the 19th century. The Vaal Dam lies on the Vaal River in Deneysville just south of the border between Gauteng and the Free State. It is also important to note that the Vaal River is the longest river wholly within the borders of South Africa. ''Vaal'' is a D ...

Olifants River (Limpopo)
The Olifants River, Lepelle, iBhalule or Obalule ( af, Olifantsrivier; pt, Rio dos Elefantes) is a river in South Africa and Mozambique, a tributary of the Limpopo River. It falls into the Drainage Area B of the Drainage basins of South Africa. The historical area of the Pedi people, Sekhukhuneland, is located between the Olifants River and one of its largest tributaries, the Steelpoort River. Course The Olifants River has its origin between Breyten and Bethal, Mpumalanga Province. It flows north towards Limpopo Province through Witbank Dam and then the Loskop Dam and is forced east by the Transvaal Drakensberg, cutting through at the Abel Erasmus Pass and then flowing east further across the Lowveld to join with the Letaba River. It crosses into Gaza Province, Mozambique, after cutting through the Lebombo Mountains by way of the Olifants Gorge, becoming the ''Rio dos Elefantes'', and finally joining the Limpopo River after 40 km before it enters the Indian Ocean at Xa ...

Dams In South Africa
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] |
Department Of Water Affairs
The Department of Water and Sanitation is one of the departments of the South African government. It is responsible for the state of water and sanitation in South Africa. In May 2009, following the election of Jacob Zuma, the Department of Water Affairs and Forestry was divided, with the forestry responsibility being transferred to the Department of Agriculture, Forestry and Fisheries. The Department of Water and Sanitation was established in May 2014 by President Jacob Zuma with former Gauteng Premier Nomvula Mokonyane becoming the first Minister (26 May 2014 – 28 January 2018). She was replaced by Gugile Nkwinti. Corruption and incapacitation The department has developed a reputation for fraud, corruption and procurement irregularities. The 2019/20 financial year report noted R10-billion had been squandered by the department, and the 2020-21 financial report has found another R10-billion in irregular expenditure. As a result of this widespread, large-scale and persiste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Vaal Dam in South Africa was constructed in 1938 and lies 77 km south of OR Tambo International Airport. The lake behind the dam wall has a surface area of about and is 47 meters deep. The Vaal Dam lies on the Vaal River, which is one of South Africa's strongest-flowing rivers. Other rivers flowing into the dam are the Wilge River, Klip River, Molspruit and Grootspruit. It has over of shoreline and is South Africa's second biggest dam by area and the fourth largest by volume. History The construction of Vaal Dam started during the depression of the early thirties and the dam was completed in 1938 with a wall height of above lowest foundation and a full supply capacity of . The dam is a concrete gravity structure with an earthfill section on the right flank. It was built as a joint venture by Rand Water and the Department of Irrigation (now known as the Department of Water Affairs).

Komati River
The Komati River, also known as the Inkomati River or Incomati River (in Mozambique, from Portuguese Rio Incomati), is a river in South Africa, Eswatini and Mozambique. Originating in north-western Eswatini, it is joined by the Crocodile River in the Lebombo Mountains, enters far south-western Mozambique below the border town of Komatipoort, and enters the Indian Ocean around north-east of Maputo. It is long, with a drainage basin in size. Its mean annual discharge is 111 m3/s (3,920 cfs) at its mouth. The name Komati is derived from ''inkomati'', meaning "cow" in siSwati, as its perennial nature is compared to a cow that always has milk.

Kriel Power Station
Kriel Power Station in Mpumalanga, South Africa, is a coal-fired power plant operated by Eskom. It is located about 4 km from Matla Power Station just outside the town of Kriel (Emalahleni Local Municipality, Mpumalanga). In contrast with most other Eskom power stations, the turbine generators at Kriel are each housed in a separate building rather than the more common single turbine hall. When Kriel was completed in 1979 it was the largest coal-fired power station in the Southern Hemisphere. It was also one of the first stations to be supplied with coal from a fully mechanised coal mine. History On 25 July 2022, the entire power station tripped. Eskom said the first fault caused units 1, 2 and 3 of the power station to trip, while the second fault tripped units 4 and 5. Unit 6 was already offline. Power generation The station has six 500MW units for a total installed capacity of 3,000MW with turbine Maximum Continuous Rating at 36.90%. See also * Fossil-fuel power pl ...
