The City of Cape Town’s Water and Sanitation Directorate has announced a series of maintenance works on the water supply infrastructure. These necessary upgrades and repairs are integral for the long-term benefit of customers. However, residents in the affected areas may experience disruptions in their water supply during the maintenance period, which will take place from June 21st to June 23rd.
Zero-Pressure Tests
The maintenance works will include zero-pressure tests for several areas, including Glencairn and Glencairn Heights, Mowbray, Salt River, Woodstock, Claremont, Rondebosch, and Kenilworth. These tests will take place overnight from 21:00 to 04:00, from June 21st to June 22nd. The tests are crucial in determining unmapped inflows before installing smart pressure-reducing valves. Residents in these areas may experience low water pressure or no water supply during the testing period.
Conditional Testing
The City will also conduct conditional testing to ensure the pressure reducing valves (PRVs) in the water supply network are functioning effectively. This process helps manage pressures at determined settings, preserving the pipeline’s lifespan and minimizing water wastage due to pipe bursts. While pressure fluctuations may occur during the testing, the impact will be minimized as much as possible. Both zero-pressure and conditional testing are part of the City’s Water Demand Management Strategy, aiming to reduce pipe bursts and water wastage by effectively managing water pressure.
Maintenance Work
Maintenance work involving pipe and valve installations, repairs, and replacements will be carried out in several locations. Extension 12 and Kanonkop in Atlantis will experience a water supply disruption from 08:00 to 17:00 on June 22nd due to valve replacements. Water tankers will be provided for domestic consumption during this period. The main water supply pipeline in Hanover Park will also be shut off from 09:00 to 13:00 on June 22nd, allowing for water meter installation. The water supply may be intermittently disrupted in this area during the alternate water supply rerouting process.
Furthermore, the main water supply of Bofors Circle from Tripper Way to Carrier Way in Epping will be shut off overnight from 19:00 on June 22nd to 02:30 on June 23rd. This disruption is necessary for the safe replacement of a bulk water meter. A water tanker will be provided for consumption if needed.
Mitigating Disruptions
During these planned water supply disruptions, the City ensures minimal disruption to the water supply through careful planning and site management. However, maintenance work can sometimes be more complex than anticipated, possibly resulting in extended work duration. Residents may experience discolored or milky water after the supply is restored due to trapped air in the pipes, but this issue resolves itself quickly when the water rests.
Preparing for Disruptions
To prepare for planned water supply disruptions, residents are advised to store sufficient water in clean, sealed containers and keep taps closed to prevent water loss or damage when the supply is restored. Residents can stay updated on maintenance work and locations of water tankers by following the City of Cape Town’s Twitter account, @CityofCTAlerts.
This planned maintenance not only reflects the City’s commitment to proactive infrastructure management but also ensures a sustainable water supply for its residents. The City regrets any inconvenience caused by the maintenance works but emphasizes the importance of these upgrades for the long-term benefit of customers. It is key for residents in the affected areas to be aware of the upcoming changes and make necessary arrangements.
