About 1,750 homes and businesses in Fife have been left without water after an 8in (20cm) water main burst.
Scottish Water said supplies were lost in Leslie from about 06:00.
A spokesperson said a team was on site at Monk’s Walk but the repair was complex due to the proximity of high-voltage power cables in the area.
Scottish Water is liaising with Scottish Power Energy Network (Spen) and a bottled water distribution has been set up at the Greenside Hotel.
Bottled water will also be delivered to vulnerable customers signed up to the Priority Services Register.
Tankers have been brought in to help restore supplies to some customers.
A Scottish Water spokesperson said: “We are tankering water into the network to try to bring some customers back into supply, although this may be intermittent.”
They added: “We are working as quickly as we can to complete the repair, with the assistance of Spen to ensure the work is carried out safely, due to the high voltage cables in the area.”
