The Water and Sanitation Department will conduct zero pressure tests on the main water supply in the Claremont, Kenilworth, Newlands and Rondebosch areas on Wednesday February 10.
This will result in the disruption of the water supply to these areas on the day from 7pm until 2am the following morning.
Residents are advised to store water in clean, sealed containers.
Residents are also advised to make sure that their taps are left in the closed position during this period to prevent any water loss and/or damage when the supply is restored.
