Homes and businesses in Chorley have been left without water this afternoon.
Properties in the PR7 area have been affected after a mains network on Chancery Road, in Astley Village, was damaged.
It means they have had either no water coming from their taps or just a trickle since 1.10pm.
A United Utilties spokesman said: “A third party carrying out work on Chancery Lane has unfortunately damaged a water pipe.
“We have a team on site completing the necessary repairs to help get water flowing again.”
