CAPE TOWN AREAS SET TO EXPERIENCE 11-HOUR WATER SHUTDOWN

The City of Cape Town said planned maintenance work, including pipe and valve installations, repairs, and replacements, will result in water supply disruption to these areas:

Kramat, Macassar Beach and Sandvlei – The City will shut off the water supply to Kramat, Macassar Beach and Sandvlei on Monday, 27 July, from 08:00 until 18:00 to enable maintenance teams to carry out the emergency replacement of a faulty valve on the water supply line. The affected areas will experience no water supply during this period. 

Blackheath Water Treatment Plant – The Blackheath Water Treatment Plant will be shut down from 06:00 on Tuesday, 28 July, until 06:00 on Wednesday, 29 July. The municipality said the shutdown is required to commission the new compressor and to urgently replace the isolation valve at the cross-connection between the upper-to-lower reservoir pipeline and the Link pipeline.

Notably, during this period, there will be no water supply to the Cape Winelands supplied via the upper-to-lower pipeline. Parts of Kuils River and Zevenwacht, which are supplied via the Link pipeline, may also experience water supply disruptions while the work is underway, the City of Cape Town said.

“This planned shutdown will enable the City’s maintenance team to safely replace an offtake valve on the 1220mm diameter bulk water pipeline in Smart Street, Goodwood. Most affected areas are expected to experience low water pressure or no water during this period,” the City of Cape Town said.
