17 Jul 2023 in Where We Govern

The City’s Water and Sanitation Directorate will be doing planned work in the identified areas, which will result in water supply disruptions. The City sincerely regrets any inconvenience caused. This critical 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. Read more below:

Maintenance work – Pipe and valve installations, repairs and replacements


  • Blackheath Water Treatment Plant maintenance shutdown

    The Blackheath Water Treatment Plant will be shut down for urgent maintenance from 06:00 on Tuesday, 18 July 2023 until 06:00 on Saturday, 22 July 2023. Although water supply is being rerouted to take over the Blackheath Water Treatment Plant supply areas, residents across the city are kindly requested to reduce their water consumption during this period to eliminate unnecessary strain on the water supply. The Stellenbosch municipality has also been informed to take the necessary measures on their side.

  • Bellville CBD, Triangle Farm, Bellville South, Labiance, Greenlands, Glenhaven and Stikland

    The main water supply to these areas will be shut off from 18:00 on Wednesday, 19 July 2023 overnight until 04:30 on Thursday, 20 July 2023.This will enable the maintenance team to repair and replace control valves on the pipeline safely and will require that the water supply be shut off for the duration.


The City sincerely regrets any inconvenience caused.


What residents need to know about larger-scale planned water supply disruptions:

  • 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.
  • 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.
  • Sometimes the maintenance work can be more complex than anticipated, which means the work could take longer.
  • 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 Twitter account.


How residents are advised to prepare for planned water supply disruptions:

  • Store enough water in clean, sealed containers for use during this period.
  • Keep your taps closed to prevent any water loss and/or damage when the water supply is restored.
