Residents in northern suburbs of Cape Town have been advised that water in the distribution system may be discoloured over parts of the northern suburbs. 

This is due to the water quality of the Wemmershoek Dam having been impacted by the severe stormy weather over the long weekend. 

DISCOLOURED WATER IN PARTS OF CAPE TOWN 

The City of Cape Town said it is conducting ongoing investigations and tests to monitor the water quality, which remains safe to drink and use.

The municipality advised residents that water in the distribution system coming from the Wemmershoek Water Treatment Plant (WTP) over parts of the city could be discoloured.

“This is due to the water quality of the Wemmershoek Dam having been impacted by the severe stormy weather this past weekend. The turbulence in the dam affected the quality of the inflow to the Wemmershoek WTP. 

“Even though treated, the water still had a turbidity count higher than the aesthetic standard limit as published in the South African National Standard for drinking water (SANS 241:2015),” the City of Cape Town said.

The affected areas are primarily the northern suburbs such as:

  • Kraaifontein
  • Joostenbergvlakte
  • Wallacedene
  • Scottsdene
  • Bracken Heights
  • Bonnie Brae
  • Vredekloof
  • North Pine 
  • Morgenster Hoogte

The City of Cape Town said the possible impact to the affected areas are being mitigated by blending with water from other parts of the bulk water network. Intensive water sampling and ongoing testing are being conducted even though it is anticipated that the turbidity value will be within the SANS (241:2015) limit as a result of the blending
