Repairs to a burst water main may cause supply disruptions to Bundoran and surrounding areas Uisce Eireann (UE) have said.
It comes as the town hosts the biggest festival of the year in the town - Sea Sessions, which attracts thousands of extra visitors to the south Donegal venue this coming weekend.
A traffic management plan will be in place for the duration of the works.
Works are scheduled to take place until 11pm on 15 June.
UE recommend that you allow 2-3 hours after the estimated restoration time for your supply to fully return.
Customers are asked to note the following reference number and enter it into the search bar on the Uisce Eireann website should you wish to return for an update: DON00064190.
