Scottish Water has been working to restore supplies to 6,000 homes in the Cumbernauld area, following a burst water main.
The areas affected are in East Carbrain, West Carbrain, Town Centre, Seafar and Kildrum.
Scottish Water set up a bottled water distribution site at the council offices at Bron Way, Cumbernauld, for those affected.
Staff from the public utility were on site to offer advice to customers.
In a statement, Scottish Water said repairs to the burst main would be completed “as quickly as possible”.
It also apologised for any inconvenience caused to customers.
