Irish Water says supply has been restored in a County Limerick village, which has seen residents without water for several days.
Irish Water had hoped to restore supply to Ardagh by this Tuesday afternoon after tankers began delivering water to the reservoir.
However, the State-owned utility said a burst water main, this Wednesday, had caused "additional delays".
"Crews were immediately mobilised to repair the water main and a second tanker was brought in to replenish the reservoir. A full water supply has now been restored to all customers in the area," said a spokesperson for Irish Water.
"We will continue to monitor the situation in Ardagh over the coming days and take any action required to prevent any further disruption," he added.
