A border area of the Irish Republic has come to the aid of water-depleted neighbours in Northern Ireland.
Louth Council is to deliver at least 100,000 litres of drinking water per day by tanker to the Newry area on the northern side of the Irish border.
It comes as Scotland promised to send further supplies of bottled water while the region's water crisis is dealt with.
Drogheda Mayor Paul Bell welcomed the decision by Louth County Council to assist its neighbouring local authority.
"I am delighted that Louth County Council has been able to respond to my call for treated water to be sent to the Newry & Mourne administrative area as a matter of urgency", Mr Bell said.
"This should have happened when the crisis first broke out and hopefully we will now have in place procedures to deal with similar situations in future.
"Such arrangements can only help communities on both sides of the border, especially given the extremes of weather that we are now told we must expect in future."
Initially, 10 tanker-loads of water will be transported by Northern Ireland Water from Dundalk each day with the emergency supply arrangement subject to review.
Meanwhile, the Scottish Government has arranged for a further delivery of bottled water to help authorities in Northern Ireland meet the needs of households cut off from mains supplies.
Scottish Water has organised for five more lorry loads, approximately 120,000 litres of bottled water to be sent across to Northern Ireland.
