Technicians worked throughout the night into Sunday on repairs to a major pipe that burst, leaving several areas without water in Johannesburg.

“The solution requires a number of valves to be closed to allow the pipe to drain faster and ensure safe working conditions. A preliminary assessment has indicated that a number of areas will be affected,” Rand Water told customers in a series of tweets on Saturday.

The list of potentially affected areas included: Bedfordview, Wychwood, Primrose Hill, Dinwiddie, Northridge, Sunnyridge, Fishershill, Primrose, Isando, Glen Marais, Klopperpark, Kempton Park, Van Riebeeck Park, Spartan, Medley (Boksburg) Germiston Station, Spoornet East Industrial, Wadeville, Tembisa, President Park, Halfway House Diepsloot, Rooihuiskraal, and Linmeyer.

Technicians diverted the supply of water to a different pipeline to ensure the stability of the network.
