From about 1am tomorrow morning (Sunday) around 100,000 Uisce Éireann customers in North Dublin will be without water.
It's due to the utility facilitating a new pipeline connection, between Ballycoolin and Swords.
Customers in Swords, Malahide, Portmarnock and Donabate, will primarily be affected.
#ICYMI: A significant water outage is planned for Sunday, 26 February in order to progress a crucial project to upgrade and secure the water supply for over 350,000 customers across North County Dublin.

Works are scheduled to be completed by about 11am, with water supply in most areas returning to normal at about 12pm.
Uisce Éireann says the new pipeline - a €28 million investment - will secure water supply to customers in the area for the next 40 years.
Head of Asset Operations, Tom Cuddy, noted 350,000 people were due to be without water originally, but network rezoning reduced the number to 100,000.
The body says currently "water supply network serving the North County Dublin Region depends on a single large-diameter, concrete water pipeline that was built in the 1960s, connecting Ballycoolin Reservoir to Swords."
