The 25m-segment of the faulty pipe on Insado Road has been cut and removed across Isando Road.
Excavation works for preparation of bedding to lay the new steel pipe are also completed, said Themba Gadebe, spokesperson for the metro, on Wednesday afternoon.
The connection of the pipe to the existing water network and restoration of water supply will be finalised by Thursday.
Although the metro said the water supply had been shut down to make way for the repairs, ward councillor Jaco Terblanche said most residents had water the past day or so.
However, he warned that a shut down could still occur, which would leave many residents with low water pressure or no water at all.
The metro foresees that all repairs will be finished before sunrise on September 13.
The affected areas, according to the metro, are:
• Allen Grove
• Aston Manor
• Bonaero Park
• Esther Park
• Glen Erasmia
• Glen Marais
• Isando Industrial area
• Kempton CBD
• Nimrod Park
Water tankers have been made available to supply water to the following areas:
• Norkem Park
• Oranjehof on Ascolana street
