Up to 20,000 properties in Stirlingshire and around Glasgow are being affected by a burst water main, Scottish Water has said.
The utility firm confirmed on Friday that emergency repairs were being carried out on a water main that burst in Carbeth, Stirlingshire.
Homes in Bearsden, Milngavie and Clydebank have been affected. Scottish Water warned that customers could experience no water, low pressure or discoloured water.
An on-site team located the burst on a 21-inch main in a field at Edenmill on Stockiemuir Road.
Up to 20,000 properties are being affected by the damaged main, and investigations to establish the full extent of the burst are still ongoing.
Properties affected are in the G61 Bearsden, G62 Milngavie, G63 Carbeth, and G81 Faifley areas.
Scottish Water said it was trying to find ways to get clean water to those affected and that bottled water will be provided to vulnerable customers.
A company spokesperson said: “Our teams are working to get this burst repaired as soon as possible.
“We apologise for any inconvenience to our customers and thank them for their patience and understanding while this repair is completed.”
