Residents on the Black Isle have had their water supplies disrupted after a mains pipe burst.
Scottish Water said repairs were being made to the pipe near the A9's Tore Roundabout north of Inverness.
The company said a water inspector was carrying out emergency adjustments to the network to bring all customers back into supply while repairs are ongoing.
Scottish Water said: "We apologise for any inconvenience this may be causing customers."
The utilities company said customers in several areas of the Black Isle were affected with low pressure or no water in the early hours of Monday.
A spokesman said: "Our local team has re-zoned our network in order to restore water supply to customers as quickly as possible.
"We are using road tankers to supplement storage tanks that serve the area, to restore and maintain supplies until the repair is complete.
"Engineers are currently working on site to make repairs. To allow this to be done safely, traffic management is in place on the A9 north of Tore, reducing the road to a single lane."
