What residents need to know about planned larger-scale water supply disruptions:
What to expect
The City advises that maintenance work can sometiemes be more complex than anticipated, resulting in longer-than-expected periods of water supply disruptions.
For a short period after water supply is restored, the water may be discoloured or milky in appearance due to the presence of trapped are in the pipes. If left to stand, the water will become clear in colour again.
How to prepare
Residents are encouraged to keep taps closed to prevent any water loss and/or damage, as well as store enough water in clean, sealed containers to last during this period.
Pressure management installations and operations
Zero-pressure testing and step testing form part of the installation process for the City’s pressure management technology. Tests are done in advance to determine if any unmapped inflows need to be considered before the instalment of smart pressure-reducing valves (PRV).
Residents in affected areas may experience low water pressure or no water supply during this overnight testing period.
Conditional testing ensures that the PRVs in the water supply network are operating effectively and managing the pressure at the detemined settings to preserve the pipeline’s lifespan and reduce the occurence of pipe bursts and water wastages.
Residents in affected areas may experience fluctuations in water pressure during this period.
This work forms part of the Water and Sanitation Directorate’s infrastructure maintenance programme to ensure the future continuity of the City’s water supply.
