Johannesburg Water Sources: The Evolution of Urban Water Supply
The growth of Johannesburg from a mining camp to a major metropolis necessitated a dramatic evolution in how the city sourced and managed its water. In its earliest days, the town relied on small, localized natural sources, but as the population and mining operations expanded, the need for a sophisticated, large-scale infrastructure became critical for survival and economic growth.
Early Water Sources and Private Concessions
Initially, Johannesburg obtained its water from three primary sources: a spruit (a small stream) in Fordsburg at the western end of Commissioner Street, the Natalspruit at the eastern end of Commissioner Street near Jeppestown, and a natural spring on the Parktown ridge, where the Johannesburg General Hospital is currently located.
As demand surged, private organizations stepped in to fill the gap. The Braamfontein Water Company operated two wells in the Parktown region, while the Vierfontein Syndicate provided water for both drinking and mining purposes. A pivotal moment occurred in 1887 with the Sivewright Concession, granted by the South African Republic (ZAR). This established the Johannesburg Waterworks and Exploration Company. Although James Sivewright held the concession, he was not obligated to supply the water himself; by 1889, he sold the rights to the Johannesburg Waterworks, Estate and Exploration Company Limited, owned by Barney Barnato.

The company developed a dam in what is now Doornfontein (the current site of Ellis Park Stadium) and pumped water to a reservoir on the ridge above Saratoga Avenue. This gravity-fed system provided 3,409,569 liters during the rainy season. However, the system was insufficient and expensive. By 1892, residents petitioned the Sanitary Board regarding the lack of supply and high costs, which reached 15s per gallon and a monthly metering fee of 5s.
By 1895, while the company supplied 4,091,400 liters daily, a severe drought forced the use of mules and carts to transport water to higher elevations. Furthermore, water quality remained a concern, as all water had to be boiled before it was safe for consumption.
The Shift Toward Public Management
In 1895, the ZAR government appointed a commission of enquiry to investigate water quality and future supply. The commission recommended that water management be transferred to a public authority, though this transition was delayed by the outbreak of the Second Boer War in 1899.
Despite the political instability, infrastructure continued to expand. In 1898, the Johannesburg Waterworks Company sank boreholes on the farm Zuurbekom. This site tapped into a natural aquifer (an underground layer of water-bearing permeable rock) spanning 466 km, eventually producing 34,095,000 liters per day. The Zuurbekom Pumphouse, built in 1899 to extract water from dolomite rocks beneath the wetlands for the Central Witwatersrand, remains operational today. It was declared a National Monument in 1975 and a Provincial Heritage Site in 2000.

Following the British takeover of Johannesburg in 1901, the push for public control was renewed. The Witwatersrand Water Supply Commission was formed on November 4, 1901. Within three months, it recommended the creation of the Rand Water Board, a public entity designed to supply water to the mines and towns of the Witwatersrand, stretching from Springs in the east to Randfontein in the west.
The Board initially utilized boreholes in the Klip River bed. However, by 1914, the need for a more sustainable source led to the construction of a barrage on the Vaal River, located 64 km south of Johannesburg. The Vereeniging Pumping Station opened on July 27, 1923, pumping water through 137 cm pipes from an elevation of 1,432m up to 1,828m on the Witwatersrand.
Large-Scale Modern Projects
To meet ever-increasing demand, the Vaal Dam was completed in 1937, situated 80 km south-east of the city. The most recent major expansion was the Lesotho Highlands Water Project, initiated in 1998. This massive undertaking involved constructing several large dams and pipelines to transport water from Lesotho into the Vaal Dam in South Africa.

Frequently Asked Questions
What were the first water sources used in Johannesburg?
The town initially relied on three sources: a spruit in Fordsburg, the Natalspruit near Jeppestown, and a spring on the Parktown ridge.
Who was Barney Barnato in the context of Johannesburg's water?
Barney Barnato owned the Johannesburg Waterworks, Estate and Exploration Company Limited, which purchased the water supply concession from James Sivewright in 1889.
What is the significance of the Zuurbekom Pumphouse?
The Zuurbekom Pumphouse was built in 1899 to extract water from a vast 466 km natural aquifer in dolomite rocks. It is still operational and is recognized as a Provincial Heritage Site.
How did the Rand Water Board change water management?
The Rand Water Board shifted water supply from private, profit-driven companies to a public authority, ensuring a more coordinated supply for the towns and mines across the Witwatersrand.
Where does Johannesburg get its water from today?
Modern supply relies on large-scale infrastructure including the Vaal Dam and the Lesotho Highlands Water Project, which transports water from Lesotho to South Africa.
