Almost 2,000 homes in Fife have been left without water for more than nine hours after a main burst on Sunday morning.
Scottish Water has warned a repair of the eight inch main in Leslie was being “complicated” due to its proximity to high voltage electrical cables.
The supplier said it was liaising with Scottish Power Energy Network (SPEN) to rectify the issue, but warned it may take some time.
Bottled water points are being set up, while vulnerable residents will have containers sent to them based on their listing on the Priority Services Register.
It is thought as many as 1,750 homes and businesses could be affected by the stoppage.
We are working as quickly as we can to get water supplies restored,” a spokesperson for Scottish Water said.
“However, we must work closely with SPEN to ensure the repair can be carried out safely, due to the presence of the high voltage cables.
“This may mean that the repair will take a little longer than normal and we apologise to all our customers affected by this issue.”
