Rand Water has urged water consumers within its area of supply to use water sparingly.
Rand Water Media Relations Manager, Justice Mohale, said due to technical challenges, the capacity at one of the main engine rooms has been reduced by 20%.
With temperatures expected to increase from [Thursday] throughout our area of supply, we appeal to consumers to use water wisely, as doing so will assist in alleviating pressure on the reduced capacity, Mohale said.
He said the engine room is estimated to be restored to its normal operating capacity within the next few days.
