Since 1903, Rand Water has been a bulk water supplier to the Gauteng area. Rand Water purifies raw water from the Vaal Dam at its two treatment plants situated at Vereeniging and Zuikerbosch before pumping it to Local Authorities reservoirs and Rand Water reservoirs for domestic, industrial and public use by about 10 million people.
Rand Water came into being in 1903 using surface run-off and boreholes as its water source. In 1923, the Vaal Development Scheme was completed which included the impoundment of water in the Vaal River Barrage and the purification and pumping of water from Vereeniging to Johannesburg. Rand Water is the only water supply utility in the world that has to provide water to a major industrial and urban complex that is not situated on a major river or waterway. Rand Water’s supply system runs from Vereeniging to Pretoria and from Krugersdorp to Springs. Water is lifted about 380m from the Vaal River to the higher areas of the Witwatersrand.
