Planned water supply maintenance for 12 - 23 February <div><div><strong style="text-decoration:underline;">Zero-pressure tests (ZPT) and conditional assessments</strong> will be done on the water supply network in the following areas:</div><div><br></div><div><strong>Tuesday, 13 February 2024 from 09:00 until 16:00: </strong>Cherrywood Gardens, Roundhay, Lionviham, Kalamunda and Audas Estate in Bizweni (Somerset West).</div><div><br></div><div><strong>Wednesday, 14 February 2024 from 09:00 until 16:00:</strong> Somerset Ridge, Westridge and Audas Estate in Bizweni (Somerset West).</div><div><br></div><div><strong>Thursday, 15 February 2024 from 09:00 until 16:00:</strong> Polkadraai (Blackheath) and Claremont.</div><div><br></div><div><strong>Friday, 23 February 2024 from 10:00 until 16:00:</strong> Westlake Industrial area.</div><div><br></div></div><div style="text-decoration:underline;"><strong>Pressure management installations and operations</strong></div><div>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. </div><div> </div><div>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. </div><div> </div><div>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.</div><div> </div><div>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.</div><div> </div><div><strong style="text-decoration:underline;">Maintenance work, including pipe and valve installations, repairs and replacements </strong>will result in water supply disruption to these areas: </div><div> </div><div><strong>Brackenfell</strong></div><div>The maintenance team will be replacing a 400mm diameter meter insert on the Brackenfell pipeline <strong>from 10:00 until 15:00 on Tuesday, 13 February 2024</strong>. The local reservoirs supplying the area will be filled up in advance and no impact is anticipated for the residents. This notice is merely as a precautionary measure. </div><div><br></div><div><strong></strong><strong>Thornton and Grand West</strong> </div><div>The maintenance team will be doing repairs to the scour valve as well as replacing a meter insert on the 535mm diameter pipeline in Thornton <strong>from 10:00 on Wednesday, 14 February 2024 overnight until 04:00 on Thursday, 15 February 2024</strong>. The water supply will be shut off during this period to enable the work to be done safely. Residents are kindly requested to store sufficient water for domestic use. Water tankers will be made available to supply water for domestic use where required.</div><div><br></div><div>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. </div><div> </div><div>The City sincerely regrets any inconvenience caused.</div><div> </div><div style="text-decoration:underline;"><strong>What residents need to know about larger-scale planned water supply disruptions:</strong></div><div>1.<span style="white-space:pre;"> </span>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 to the water supply</strong>.</div><div>2.<span style="white-space:pre;"> </span><strong>All sites where water and sanitation repairs and upgrades are conducted are deemed to be construction sites</strong> and, as such, <strong>are off-limits to members of the public</strong>.</div><div>3.<span style="white-space:pre;"> </span>Sometimes the maintenance work <strong>can be more complex than anticipated, which means the work could take longer</strong>.</div><div>4.<span style="white-space:pre;"> </span>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. If<strong> left to stand in a glass, the appearance will become clear</strong>, like normal.</div><div><br></div><div>For updates on the maintenance work (and location of tankers where applicable), follow <strong>@CityofCTAlerts </strong>which is a City of Cape Town X account (formerly Twitter).</div><div> </div><div style="text-decoration:underline;"><strong>How residents are advised to prepare for planned water supply disruptions:</strong></div><div>1.<span style="white-space:pre;"> </span><strong>Store enough water</strong> in clean, sealed containers in advance for use during this period.</div><div>2.<span style="white-space:pre;"> </span><strong>Keep your taps closed to prevent any water loss and/or damage </strong>when the water supply is restored. </div><div><br></div><div><br></div><div>End<br><br></div>2024-02-08T22:00:00ZGP0|#1d539e44-7c8c-4646-887d-386dc1d95d70;L0|#01d539e44-7c8c-4646-887d-386dc1d95d70|City news;GTSet|#62efe227-07aa-45e7-944c-ceebacca891dGP0|#42305b06-67ec-4657-9272-641a0ea14201;L0|#042305b06-67ec-4657-9272-641a0ea14201|water supply;GTSet|#2e3de6c1-9951-4747-8f53-470629a399bb1Media Office, City of Cape Town0
