Water meters will go off in Sandton over night, from 7pm on Thursday, the 02nd January 2025 until Friday, the 3rd January 2025.
Johannesburg Water (JW) said in a notice to residents, this is an intervention, to spread supply to the rest of the network.
Affected areas are Linbro Park, Marlboro, Illovo, Bryanston and Morningside.
JW also said water might return slightly brown, due to calcified mineral deposits caused by older pipes.
Water might also take several hours before the system fully recovers.
