A burst main has left several areas in the Cahir-Clonmel and Fethard areas without water for over 24 hours.
The problem covers a vast area with supplies out in parts of Clonmel, Kilsheelan, Powerstown, Lisronagh and stretching as far as Killusty and Kiltinan.
Irish Water say it could be as late as 11 o'clock tonight before supply is restored in some areas.
