The Mogalakwena mine is a large open pit mine located in the north-western part of South Africa in Mokopane, Limpopo. Mogalakwena represents one of the largest platinum reserves in South Africa having estimated reserves of 264.9 million oz of platinum. The mine produces around 310,000 oz of platinum/year.

Since opening their doors in 1979 and rapidly becoming South Africa’s largest waste management company, they have been first to market with many waste management solutions. Some are still recognised as best practice.
They remain pioneers today because the drive to look for better ways of doing things is deeply embedded in our culture.

The eMalahleni Water Reclamation Plant was commissioned in 2007, the plant was upgraded to treat an average of 30,000 m3l/day for Anglo American Thermal Coal/BHP Billiton
Aveng Water was also awarded the contract to increase the plant’s capacity further, to treat up to 50,000 m3l/ day.
This flagship plant is the first largest water treatment plant to successfully treat Acid Mine Drainage (AMD).
It is a recipient of several industry awards and demonstrating Aveng Water’s expertise in treating mine water at affordable rates to generate new water resources.
In line with Aveng Water’s focus on zero waste, pure gypsum sludge, which is a by-product of AMD treatment, is sold to the manufacturing industry for use as gypsum board and building materials.

Reinforced concrete reservoirs are used to store clean water for release on demand. They are usually made of concrete reinforced with steel bars or steel mesh. Chemical additives are often mixed with the concrete to make it more impermeable to water. Reinforced concrete reservoirs are built at the site on a solid foundation. If the base is not solid enough, another site should be chosen, or arrangements made to stabilize the construction.
To protect the water from contamination, the reservoir is covered with a roof, usually made of reinforced concrete, but other materials can be used. In the top of the tank an aeration pipe with a screen allows fresh air to circulate in the tank, but keeps rodents and insects out. A manhole in the roof allows access to the tank for cleaning and repairs. Water flows into the reservoir through an inlet pipe above the water level in the reservoir. This prevents back-flow and allows the water to be heard entering the tank. At this point, a chlorine solution is often added for disinfection. Outlets are built a little above the floor of the reservoir, which has a slope pitched down towards one point with a washout pipe for flushing.

Mohale Dam is a concrete faced rock-fill dam in Lesotho. It is the second dam, under Phase 1B of the series of dams of the proposed Lesotho Highlands Development Authority (LHDA), which will eventually include five large dams in remote rural areas of Lesotho and South Africa.The Mohale Dam was awarded the 2005 Fulton Awards by the Concrete Society of South Africa as having the “Best Construction Engineering Project and Best Construction Technique.”
