Dublin City Council is expected to announce later today if it intends to continue restricting water supplies throughout the weekend.
Overnight restrictions were introduced earlier this week in an effort to conserve supplies.
Supplies ran low after some householders left taps on to prevent their pipes from freezing during the cold spell.
Elsewhere, snow and ice clearing operations will begin on the M9 motorway in Co Kildare this morning, leading to delays for motorists.
The works, which begin at 8am, will affect the northbound and southbound carriageways at various times during the day.
Pedestrians have been warned to take care as footpaths remain dangerous as the ice melts.
Meanwhile, Bus Éireann says that most of its services are operating normally, but there is some disruption in the northeast and east.
