Supplies in Laois, Offaly and Westmeath have been restored but customers may experience low pressure.
Uisce Éireann crews have been working tirelessly to restore water supply to homes, farms and businesses across the Midlands.
Following the recent impact of Storm Éowyn the majority of water supplies in Offaly and Laois have been restored.
Some customers may experience low pressure or disruptions as the networks begin to recharge.
Meanwhile power has been restored at most Westmeath locations with Uisce Éireann running the remaining sites on generators, as many rural reservoirs and pumping stations across the Mullingar Regional Supply were impacted.
