A number of areas in the City of Cape Town will be without water from Wednesday, 4 October due to planned maintenance.
The municipality’s Water and Sanitation Directorate will be doing planned work in the identified areas, which will result in water supply disruptions.
PARTS OF CAPE TOWN WILL BE WITHOUT WATER THIS WEEK
The planned maintenance work will result in water supply disruptions to these areas:
ZERO-PRESSURE TESTS AND CONDITIONAL ASSESSMENTS
Claremont, Newlands and Rondebosch
Step-testing will be done on the water supply network in these areas from 21:00 on Wednesday, 4 October 2023, overnight until 04:00 on Thursday, 5 October 2023, and again from 21:00 on Thursday, 5 October 2023, overnight until 04:00 on Friday, 6 October 2023. This will enable the maintenance team to do conditional assessments on the water supply into the area.
PRESSURE MANAGEMENT INSTALLATIONS AND OPERATIONS
Zero-pressure testing and step-testing are part of the installation process for pressure management technology. Tests are done in advance to see if any unmapped inflows need to be considered before installing smart pressure-reducing valves.
The City of Cape Town said in the affected areas, some residents may experience low water pressure, and some may have no water coming out of their taps for some time during this overnight testing period. It is not possible to predict which areas or streets will experience disruptions.
“Conditional testing on the other hand ensures that the pressure-reducing valves (PRVs) in the water supply network are operating effectively and managing the pressures at the determined settings to preserve the lifespan of the pipeline and reduce the occurrence of water wastage resulting from pipe bursts. Pressure fluctuations may be experienced, but will be minimised as far as possible,” the municipality said.

MAINTENANCE WORK – PIPE AND VALVE INSTALLATIONS, REPAIRS AND REPLACEMENTS
This work will result in the water supply disruption to these areas:
Site B – Nonkqubela area (Khayelitsha)
The water supply to this area will be shut-off from 08:00 until 16:00 on Wednesday, 4 October 2023. This will enable the maintenance team to safely install a 450mm diameter valve on the main water supply pipeline. Water tankers will be providing water for domestic consumption where required.
Mowbray and Rondebosch
The water supply main to these area will be shut-off from 09:00 until 19:00 on Thursday, 5 October 2023, to enable the maintenance team to install a 300mm diameter valve on the main water supply pipeline and repair fire hydrants.
