The Water and Sanitation Department will conduct zero pressure tests on the main water supply to Claremont, Kenilworth, Newlands and Rondebosch from 7pm on Thursday March 4 and Friday March 5.
This will result in the disruption of water supply on both days.
Residents are advised to store water in clean, sealed containers for use during this period and to ensure that their taps are closed to avoid water loss and/or damage when the supply is restored.
