Conditional assessments are presently being done on the water supply network in these areas until Thursday, 30 November 2023. This will result in the possibility of lower than usual pressures experienced for up to four hours during the day in some parts as the assessments progress. The period has been increased from 1,5 hours to allow for adequate time to do the assessments.

Zero-pressure testing will be done on the water supply network in this area from 21:00 on Tuesday, 7 November 2023, overnight until 04:00 on Wednesday, 8 November 2023.

Zero-pressure testing will be done on the water supply network in these areas from 21:00 on Thursday, 9 November 2023, overnight until 04:00 on Friday, 10 November 2023.

Zero-pressure testing will be done on the water supply network in these areas from 21:00 on Thursday, 16 November 2023, overnight until 04:00 on Friday, 17 November 2023.

 

Zero-pressure testing and step-testing are part of the installation process for pressure management technology. Tests are done in advance to see if any unmapped inflows need to be considered before installing smart pressure-reducing valves. 

 

In these affected areas, some residents may experience low water pressure, and some may have no water coming out of their taps for some time during this overnight testing period. It is not possible to predict which areas or streets will experience disruptions. 

 

Conditional testing on the other hand ensures that the pressure-reducing valves (PRVs) in the water supply network are operating effectively and managing the pressures at the determined settings to preserve the lifespan of the pipeline and reduce the occurrence of water wastage resulting from pipe bursts. Pressure fluctuations may be experienced, but will be minimised 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.

 

This work will result in the water supply disruption to these areas: 

The Water and Sanitation Directorate will be repairing a faulty valve on the water supply main to this area from 08:00 and 15:00 on Sunday, 5 November 2023. Alternate water supply will be rerouted to this area during this period. No water supply disruption is anticipated other than a slight pressure fluctuation. 

The water supply to Suikerbossie bounded by Victoria Road and Bisschop Road, will be shut off from 10:00 until 17:00 on Tuesday, 7 November 2023. This will enable the maintenance team to do a tie-in on the main water supply to the area. Residents are requested to store enough water in advance for domestic consumption.

The water supply to this area will be shut off temporarily from 09:00 and 16:00 on Wednesday, 8 November 2023. This will enable the maintenance team to do planning for the replacement of a defective 200mm diameter water meter. It will result in the disruption of the water supply for the duration of the exercise. Water tankers will provide water for domestic consumption where required.

The main water supply to this area will be shut off temporarily from 09:00 and 18:00 on Thursday, 9 November 2023. This will enable the maintenance team to do the replacement of defective isolation valves on the water supply main. It will result in the disruption of the water supply for the duration of the work. 

 

The water supply to this area will be shut off temporarily from 10:00 and 18:00 on Tuesday, 14 November 2023. This will enable the maintenance team to safely do the replacement of the defective 200mm diameter water meter. It will result in the disruption of the water supply for the duration of the work. Water tankers will provide water for domestic consumption where required.   

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. 

 

The City sincerely regrets any inconvenience caused.

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 n

ormal.

For updates on the maintenance work (and location of tankers where applicable),

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.
