Around 100,000 people in north Dublin are due to be without water tomorrow morning.
Uisce Éireann is facilitating the connection of a new pipeline between Ballycoolin and Swords.
The works will primarily affect customers living in Swords, Malahide, Portmarnock and Donabate.
The utility says the upgrade will secure water supply for over 350,000 customers in the area for the next 40 years.
