The Water and Sanitation Department will replace a 225mm diameter non-return valve and a 250mm diameter control valve at the Perlemoen pump station in Bloubergstrand on Thursday December 17.
This will lead to water supply disruptions Blouberg Ridge, Bloubergstrand and West Beach.
The work will start at 9am and is expected to be completed by 5pm. The affected areas can expect low pressure, or possible total loss of supply during this period.
Residents and businesses in these areas are advised to store water upfront in clean sealed containers for use during this period.
A water tanker will be stationed at the bottom end of Gull Street near the Perlemoen pump station to provide water for domestic consumption where required.
