Residents in the southern end of Foula are facing the possibility of a Christmas without water.
Local resident Martin Smith said that the problem first arose on Monday evening and that there are now four occupied households on the isle affected by the issue.
Mr Smith said: “One of the households is owned by a family who have young children. Another of the affected households has an elderly resident.”
Scottish Water have been alerted to the fault but due to weather they have been unable to fly staff out to fix the problem.
Foula residents will be hoping that the weather abates and Scottish Water are able to attend to the fault soon or else they may have to spend Christmas without a water mains supply.
Mr Smith noted that as residents in the north of the isle were unaffected it has been possible to top up water bottles with their assistance.
However he said that there was no hope of being able to shower, or wash clothes and dishes due to the limitations caused by the fault.
