Planned water supply maintenance: 20 - 26 November 2023<p>​<br></p><p>This work will result in water supply disruptions in these areas:</p><p><strong> </strong></p><p><span style="text-decoration:underline;"><strong>Zero-pressure tests (ZPT) and conditional assessments</strong></span></p><p> <br></p><ol><li><strong>Plumstead and Wynberg</strong><br> Conditional assessments are presently being done on the water supply network in these areas <strong>until Thursday, 30 November 2023.</strong> 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 an hour and a half to allow for adequate time to do the assessments.<br><br><strong>Bellville South, Beroma, Glenhaven, Labiance and Kasselsvlei</strong><br><strong> </strong>Zero pressure testing will be done on the water supply network in these areas <strong>from 21:00 on Tuesday, 21 November 2023, overnight until 04:00 on Wednesday, 22 November 2023.</strong><br><strong> </strong><br><span style="text-decoration:underline;"><strong>Pressure management installations and operations</strong></span><br><br>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. <br><br>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. <br><br>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.<br> <br>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.<br><strong> </strong><br><span style="text-decoration:underline;"><strong>Maintenance work – Pipe and valve installations, repairs and replacements</strong></span><br> <br>This work will result in the water supply disruption to these areas: <br><strong> </strong><br><strong>Parklands</strong><br><strong> </strong>The 400mm diameter water supply main to this area will be shut off <strong>from 20:30 on Tuesday, 21 November 2023, overnight until 04:30 on Wednesday, 22 November 2023.</strong> This will enable the maintenance team to do urgent repairs to a leaking connection and replace a faulty valve. Alternate water supply will be rerouted to the area albeit at low pressure.<br><br><strong>Colorado Park and a portion of Woodlands  (Mitchells Plain)</strong><br><strong> </strong>The water supply to this area will be shut off <strong>from 09:00 until 18:00 on Thursday, 23 November 2023.</strong> This will enable the maintenance team to do a tie-in for a new development on the 200mm diameter and 300mm diameter water supply mains to the area. Residents are requested to store enough water in advance for domestic consumption.<br> <br><strong>Paarden Eiland, Lower Woodstock (Beach Road to Porter Road), Transnet, Waterfront and Foreshore</strong> <br>The test water shut-off done on the water supply to these areas from <strong>22:00 until 23:00 on Wednesday, 15 November 2023 </strong>confirmed the areas that will be impacted, but additional time is required for the preparations hence the postponement by a week. The water supply to these areas will now be shut off <strong>from 10:00 on Saturday, 25 November 2023 overnight until 24:00 on Sunday, 26 November 2023. </strong>This will enable maintenance team to do urgent repairs to a severe leak on the 915mm diameter bulk water pipeline in Paarden Eiland. Even though urgent, this work has been scheduled for a period that's least disruptive to industry. Alternate water supply will be rerouted to minimise the extent of the impact.<br> <br><strong>Constantia Shut-off 1</strong><br><strong> </strong>The water supply to, Alphen Drive, Hohenhort Avenue, Willowbrooke Lane, Brommaert Avenue, Midhurst Way and the Valley Walk will be shut off intermittently <strong>from 09:00 until 17:00 on Tuesday, 21 November 2023.</strong> This will enable the maintenance team to repair and replace valves and fire hydrants on the water supply to the area. Adjacent roads may also be affected. Residents are kindly requested to store enough water in advance for domestic consumption. <br><br><strong>Constantia Shut-off 2</strong><br><strong> </strong>The water supply to Sohland Avenue, Constantia Main Road, Pagasvlei Road, Jacaranda Way and Bellair Drive will be shut off intermittently <strong>from 09:00 until 17:00 on Thursday, 23 November 2023.</strong> This will enable the maintenance team to repair and replace valves and fire hydrants on the water supply to the area. Adjacent roads may also be affected. Residents are kindly requested to store enough water in advance for domestic consumption. <br> <br>The City sincerely regrets any inconvenience caused.<br></li></ol><table cellspacing="0" width="100%" class="ms-rteTable-default"><tbody><tr><td class="ms-rteTable-default" style="width:100%;"><p><span style="text-decoration:underline;"><strong>What residents need to know about larger-scale planned water supply disruptions:</strong></span></p><ol style="list-style-type:decimal;"><li>Careful consideration has been given to the planning of this work to ensure it is <strong>being done at a time that is least disruptive</strong> to the water supply.</li><li><strong>All sites where water and sanitation repairs and upgrades are conducted</strong> are deemed to be construction sites and, as such, <strong>are off-limits to members of the public.</strong></li><li>Sometimes the <strong>maintenance work can be more complex than anticipated, which means the work could take longer.</strong></li><li>For a short period <strong>after the supply has been restored, the water may be discoloured or look milky.</strong> This is because of trapped air in the pipes.
