Planned water supply maintenance for 7 to 10 October 2025
03 October 2025
The City’s Water and Sanitation Directorate will be doing planned work in the identified areas, which will result in water supply disruption. This critical maintenance work is done on our water supply infrastructure to benefit customers. Residents in the affected areas are encouraged to take note of the work that will take place and prepare accordingly.
Maintenance work, including pipe and valve installations, repairs and replacements
Residents are advised to store enough water in advance as a precautionary measure. Water should be stored in clean, sealed containers. This precaution does not guarantee all residents will have water disruption, but aims to ensure they are able to prepare in the event it does occur.
Planned maintenance work will result in water supply disruption to these areas:
Diep River and surrounding areas
The City’s Water and Sanitation Department will be conducting a pressure investigation on the main water supply to Diep River and surrounding areas on Tuesday, 7 October 2025, from 10:00 to 15:00. Residents may experience brief periods of no water or very low water pressure during this time. The affected areas include Diep River, Constantia, Plumstead, and Meadowridge.
Forbes Avenue and Middel Road, Rylands
The City has appointed a contractor to rehabilitate water mains in the area. Work will include installing a bypass in Middel Road (from Forbes Avenue to Duine Road) and valves at the intersections of Forbes Avenue with Middel Road and Mabel Road. This will result in the water supply being shut off on Tuesday, 7 October 2025, from 09:00 to 18:00 affecting Forbes Avenue (Flat Road to Jane Avenue) and Middel Road (between Forbes Avenue and Duine Street) as well as surrounding areas in Rylands.
Mount View and Penlyn Estate
As part of the construction of the MyCiTi bus route in Turfhall Road, the City’s appointed contractor will be installing a new 535mm water main in Turfhall Road, Lansdowne, on Wednesday, 8 October 2025, from 09:00 to 18:00. This work may result in intermittent periods of low water pressure or no water supply.
Hanover Park
The City’s Water and Sanitation Department will temporarily shut off the water supply in parts of Hanover Park on Thursday, 9 October 2025, from 09:00 to 18:00, to complete the installation of a new water main at various intersections along Downberg Road and Greenturf Road (between Lonedown Road and Hanover Park Road). The affected roads include: Downberg Road, Greenturf Road, Groenall Walk, Turfburg Walk, Hope Crescent, Ryburg Road and Lonedown Road.
This work forms part of the Water and Sanitation Directorate’s proactive infrastructure maintenance and upgrade programme, which ensures the future continuity of water supply by addressing the issue of unaccounted for water.
Zero-pressure tests (ZPT) and conditional assessments will be done on the water supply network resulting in water supply disruptions in the following areas:
Friday, 10 October 2025, from 10:00 until 17:00: Steenberg, Retreat and Retreat Industrial
Zero-pressure testing and step-testing are part of the installation process for zone management infrastructure. Tests are done in advance to see if any unmapped inflows need to be considered before installing new infrastructure (such as pressure reducing valves for pressure management).
In these affected areas, some residents may experience low water pressure while some may have no water during the testing period. Unfortunately, it is not possible to predict which exact areas or streets will experience disruptions.
Additional zone management investigations will be carried out to ensure that the existing infrastructure is operating effectively. Pressure fluctuations may be experienced, but every effort will be made to minimise the impact as far as possible.
This work forms part of the City’s Water Demand Management Strategy. Managing water pressure more effectively reduces the possibility of pipe bursts and water wastage.
The City sincerely regrets any inconvenience.
What residents need to know about larger-scale planned water supply disruptions:
1. Careful consideration has been given to the planning of this work to ensure it is being done at a time that is least disruptive to the water supply.
2. All sites where water and sanitation repairs and upgrades are conducted are deemed to be construction sites and, as such, are off-limits to members of the public.
3. Sometimes the maintenance work can be more complex than anticipated, which means the work could take longer.
4. For a short period after the supply has been restored, the water may be discoloured or look milky. This is because of trapped air in the pipes. If left to stand in a glass, the appearance will become clear, like normal.
For updates on the maintenance work (and location of tankers where applicable), follow @CityofCTAlerts which is a City of Cape Town X account.
How residents are advised to prepare for planned water supply disruptions:
1. Store enough water in clean, sealed containers in advance for use during this period.
2. Keep your taps closed to prevent any water loss and/or damage when the water supply is restored.
