Irish Water is currently investigating reports of supply disruptions in West Tipperary.
The affected areas include Currana, Grange North, Golden and surrounding areas.
The company says more information is to follow.
Separately repairs to a burst water main may cause supply disruptions to Loughloher, Ardfinnan Road, Cahir and surrounding areas.
The works are scheduled to take place from until 12:30pm on 12 March.
Irish Water recommends that customers should allow 2-3 hours after the estimated restoration time for their supply to fully return.
