Overnight water restrictions are in place until further notice in parts of south Leitrim after the impact of Storm Darragh.
Uisce Eireann says this is to allow reservoir levels to recover.
It says some pumping stations across Co Leitrim, which fill these reservoirs, remain without power.
A spokesperson added: "Overnight restrictions help us to fill reservoirs and improve supply and pressure for customers.
"As some reservoirs remain low, restrictions are scheduled to take place nightly from 9pm to 7am until further notice in the following areas:
Carrick-on-Shannon area: Hartley, Attirory
Drumshanbo/Leitrim Village: Drumshanbo town, Leitrim Village, Ballinaboy, Mullaghboy/Drumbrand, Lisdrumrea/Lisdrumfarna, Disternan, Drumcong
