Residents of St Francis Bay and Cape St Francis are asked to use water very sparingly.
The water supply to the towns’ reservoirs has been interrupted following the collapse of a suspension bridge carrying a section of the main line earlier yesterday.
A damage assessment has been done and a contractor will start repairs on Monday.
The reservoirs are being monitored and levels are currently stable.
It is, however, uncertain how long repairs will take and there is a risk that the reservoirs could dry up.
Everyone is, therefore, urged to use as little water as possible to make the available supply last as long as is possible.
