Rand Water has announced major planned maintenance at its Palmiet and Zuikerbosch systems, which will lead to water supply interruptions between 29 May and 17 July 2026.
Rand Water said the maintenance will focus on critical electrical and pumping infrastructure aimed at improving system reliability, operational flexibility and long-term water supply stability.
According to Rand Water, some pumps will need to be temporarily shut down during the maintenance period, which may affect water supply to several municipalities, industries and direct customers.
“The planned maintenance activities are necessary to improve pump availability and standby capacity. They also enhance operational flexibility across key Rand Water systems, reduce the risk of plant trips and equipment failures,” the utility said in a statement.
Rand Water said the work had been coordinated with Eskom and deliberately scheduled during the winter season, which is traditionally a low-water-demand period.
Key maintenance activities will include Eskom-related electrical maintenance at the Zuikerbosch and Palmiet systems; the installation and upgrading of motors at Zuikerbosch Raw Water Engine Room 4; replacement of critical valves and thrust bearings at Palmiet, Vereeniging and Foresthill systems; and M11 pipeline cross-connections within the Mapleton system.
The planned maintenance will affect parts of Gauteng, the North West, Free State and Mpumalanga.
Municipalities expected to be affected include the Metros of Johannesburg, Tshwane and Ekurhuleni, as well as local municipalities such as Mogale City, West Rand, Merafong, Rustenburg, Madibeng, Lesedi, Victor Khanye, Govan Mbeki, Thembisile Hani, Midvaal, Emfuleni, Metsimaholo, Ngwathe and the Royal Bafokeng Administration.
Rand Water said various industries, mines and direct customers, including Airports Company South Africa (ACSA), may also be affected.
In line with its commitment to operational transparency and excellence, Rand Water has issued a 21-day notice to all affected municipalities, industries and direct customers.
“The notification is intended to provide all customers with sufficient time to implement contingency measures and minimise potential water supply disruptions to consumers,” Rand Water said.
The utility added that regular updates on the maintenance programme would be communicated through its official channels, including social media platforms. – SAnews.gov.za
