Uisce Éireann says customers in the Athlone area will be without water early next week.
It's due to essential works being carried out on the water network there on Monday and Tuesday.
The works will take place between 9am and 5pm and may result in disruptions for those on Cartrontroy Road, Killyon Hill and Retreat Heights.
Uisce Éireann says crews will complete the works as quickly as possible to restore normal supply.
It typically takes two to three hours following repairs for normal supply to be restored to all customers.
