Residents are encouraged to start storing water, ahead of an urgent maintenance of Rand Water’s Palmiet Pump Station.
Maintenance will kick off as early as the 02nd of next month.
Areas affected are those served by the Sandton Systems, Alexander Park Reservoir, South Hills Tower, Randjieslaagte Reservoir, Linksfield Reservoirs and Midrand Systems.
Johannesburg Water said there may be poor pressure or no water at all, during the maintenance period.
Full recovery of the systems is also expected to take several days after the completion of maintenance.
Areas supplied by the Sandton and Midrand reservoirs and towers may take longer to recover because the reservoirs need to first build capacity after being empty.
Johannesburg Water committed to arrange for alternative water supply at strategic points in residential areas.
