Cape Town suburbs face planned water disruptions from 5 October

Cape Town residents in several areas are being urged to prepare for temporary water supply interruptions from next week as the City’s Water and Sanitation Directorate carries out a series of planned maintenance projects and network assessments.

The scheduled work includes a major shutdown at the Faure Water Treatment Plant (WTP), pipe and valve replacements, new connections and zero-pressure testing across parts of the city, with some work continuing into 2027.

The latest maintenance notice from the City of Cape Town outlines disruptions affecting parts of Woodstock, Strand and Grassy Park, as well as several areas where water pressure testing will take place.

Faure Water Treatment Plant

The Faure WTP will be temporarily shut down from 08:00 on Monday, 5 October until 18:00 on Wednesday, 7 October to allow essential maintenance to be carried out safely.

The work will include servicing filter valves, replacing valves and pumps on wash-water recovery tanks, maintaining chlorine pumps and inspecting inlet chambers to the turbines.

During the shutdown, water normally supplied by Faure will be rerouted from the Steenbras and Blackheath bulk water pipelines. Reservoirs supplying the affected areas will also be filled in advance to help maintain supply.

However, the shutdown will place additional pressure on the City’s bulk water storage, and residents and businesses across Cape Town are being urged to reduce their water consumption during this period.

The shutdown was initially scheduled for 28 September to 2 October but was postponed while the City dealt with an investigation and emergency repairs to a leaking 810mm-diameter pipeline in Claremont.

Woodstock

Parts of Woodstock will be affected by a pipe replacement project running from Monday, 5 October 2026 until Friday, 30 April 2027.

Water supply will be interrupted intermittently in Ravenscraig Road, Woodlands Road, Pine Road, Queens Road, Beyers Road, Warwick Street, Salmon Street, Coventry Road, Duke Road, Park Road and High Street, as well as possibly surrounding streets.

The affected areas may have no water between 08:00 and 17:00 daily when work is taking place.

The City will use trenchless technology for the pipe and valve replacements, which is intended to reduce disruption to residents and motorists.

Affected streets will be notified in advance when their water supply is scheduled to be interrupted.

Strand

Meanwhile, parts of Strand will experience a temporary water shutdown on Wednesday, 7 October from 09:00 to 18:00.

The interruption will affect parts of Broadlands Road, from the vicinity of Strandfoam Group (Pty) Ltd towards the N2, Lwandle, Helderberg Industrial and possibly surrounding streets.

The work will allow maintenance teams to connect a new connection to the existing 300mm-diameter water main.

Grassy Park

Residents in Dieman Road, Iris Road and possibly surrounding streets in Grassy Park can expect a temporary water interruption on Wednesday, 7 October from 08:00 to 19:00.

Teams will connect newly installed pipelines to the existing water supply infrastructure.

Leak detection work

Visual leak detection will take place in Melkbosstrand, Thornton and Welgemoed Lower from Monday, 5 October to Friday, 9 October, between 09:30 and 15:00.

The work forms part of the City’s water demand management measures, which aim to identify leaks and reduce water losses.

Teams will walk through the affected streets checking pipe contact points, including valves, water meters and fire hydrants. Any leaks identified will be reported to the relevant depot for repairs.

The City says this work will not result in water supply disruptions.

Zero-pressure testing

Meanwhile, several areas will also be affected by zero-pressure tests and conditional assessments, which may result in low pressure or temporary water interruptions.

The scheduled testing is as follows:

• Martindale – Bizweni: Wednesday, 7 October, from 09:00 to 16:00.
• Helderzicht, Lourensia Park, Paardevlei, Victoria Park, Silvertas, Garden Village and Carey Park: Thursday, 8 October, from 09:00 to 16:00.
• Da Gama Park, Welcome Glen and Scala Road: Thursday, 8 October, from 09:00 to 16:00.

The City says it is not possible to predict exactly which streets will experience disruptions during the testing.

Zero-pressure and step-testing form part of the installation process for zone management infrastructure. The tests help identify unmapped inflows before infrastructure such as pressure-reducing valves is installed.

The work is intended to improve pressure management, reduce the likelihood of pipe bursts and limit water wastage.

Residents in affected areas are advised to store enough water in clean, sealed containers before maintenance begins.

The City has also urged residents to keep their taps closed while the water is off to prevent water loss or possible damage when supply is restored.

Some residents may notice water appearing milky or discoloured for a short period after supply returns. The City says this is generally caused by trapped air in the pipes and should clear when the water is left to stand.

Residents are reminded that all water and sanitation maintenance sites are construction areas and are therefore off-limits to members of the public.

The City has also cautioned that some projects may take longer than expected if maintenance teams encounter unforeseen technical complications.

The municipality has apologised for any inconvenience caused, saying the planned work is necessary to maintain and improve the city’s water supply infrastructure.

Planned water maintenance will take place across parts of Cape Town from 5 to 9 October.

Some areas may experience temporary disruptions or low pressure.
