Overnight water restrictions are to be implemented on Inis Oirr from late tonight.
The restrictions will be in place each night from 11pm until 7am, to ensure a continued supply of water.
Uisce Eireann says simple conservation efforts can have a big impact on reducing supply, and is urging residents to be mindful.
These could include turning off the tap while brushing teeth, showering rather than bathing, and using a watering can instead of a hose.
