Lessees on short or long lets in these localities should first of all make sure all the taps within the leased property are closed. It is not the first time a tap has been forgotten open during the water shortage, resulting in flooding when the service is restored while the lessee is out, even incurring damages to neighbouring properties.
Secondly, most properties have a reserve water tank on the roof. This means that when the supply is interrupted, the water used in most water taps around the residence, with the exception of the kitchen (which by law has to be connected directly to the mains) will be fed by the roof-tank till the reserve supply is exhausted and the tank empty.
When the water supply returns, lessees will immediately regain a water supply in their kitchen sinks, but the rest of the system which is fed through the roof-tanks, will still see no water as these tanks normally will take a few hours to fill up due initial low water pressure, especially if the property is an apartment and the tanks are on a high rise roof.
Patience is of essence.
