Johannesburg Water says water supply from the Zuikerbosch system is gradually being restored following a 48-hour outage linked to planned maintenance by bulk supplier Rand Water.
The utility has urged residents across the city to remain patient, warning that reduced water pressure and intermittent supply are expected as the system stabilises. High-lying areas, in particular, may experience full outages and slower restoration times.
The maintenance work is being carried out in three phases and is scheduled to continue until 8 January 2026. The first phase took place from 13 to 15 December, with the second phase set for 19 to 21 December, and the final phase planned for 6 to 8 January.
Johannesburg Water managing director Ntshavheni Mukwevho said the ongoing work will have a citywide impact, depending on which systems are affected during each phase.
“Residents across the metro should expect reduced water pressure and intermittent supply. High-lying areas may experience complete outages and slower restoration,” Mukwevho said.
By Monday morning, areas including Lenasia, Randburg and parts of Johannesburg were already feeling the effects of the outage.
Mukwevho confirmed that the second phase of maintenance will begin later this week and will last longer than the first.
“From 19 December at 18:00 to 21 December at midnight, this phase will run for 54 hours. It will affect areas supplied by the Eikenhof system, including Power Park, Doornkop, Zondie, Braamfischer and Lenasia,” he said.
Johannesburg Water said it will deploy water tankers to affected communities during the maintenance period to provide relief where supply is disrupted.
Residents are encouraged to use water sparingly and to stay informed through official Johannesburg Water communication channels for updates on restoration progress and tanker deployment schedules.
