Local Authorities are again calling on people to check office blocks and schools for pipe breakages and leaks before they re-open following the Christmas and New Year holidays.
A spokesman for the Department of the Environment has said the water supply situation has stabilised across most of the country and has improved in Dublin.
Principal Engineering adviser to the Department of the Environment Gerry Galvin has said that Dublin had had a very good water supply for the past 24 hours.
Supply has exceeded demand for the past three days mainly due to the restrictions that have been in place.
Mr Galvin said that there were still problems in some areas caused by burst pipes rather than a lack of supply and he said that there were two critical periods ahead now: tomorrow when most businesses and industry return to to normal and next week when the schools are back.
In Dublin, restrictions are expected to continue for at least another 12 days.
Dublin City Council has said that water in many areas will be shut off from 6pm until 7am tomorrow.
A spokesperson for Dublin City Council has said that he expects restrictions of some form to remain in place until the middle of this month.
Households and businesses nationwide are still subject to restrictions.
Consumers who have water are being asked to make every effort to conserve supplies.
Work to repair burst pipes is continuing with night-time restrictions still in operation in many counties.
Due to the progress that has been made, night time restrictions will be lifted this evening in the following areas of Cork city: Harbour View Road, Cathedral Road, Churchfield Avenue, Rathmore Park, Audley Place, Old blackrock Road, Rockboro Avenue
Night time restrictions will however continue to apply for the time being in other affected areas.
Due to the improvement in supply the use of standpipes will be discontinued from today.
In Co Cork, repair crews will be working in the Mallow area over the coming week which may lead to short term disruptions to supplies.
Repair work is being carried out in other areas around the country including Athlone in Co Westmeath.
Improvements in supply have also been reported in Laois and Mayo.
In Leitrim, water levels in reservoirs continue to improve. But it remains necessary to turn off water supplies at night-time in all areas with the exception of the main towns and villages.
A water tanker continues to be available to supply water from 11am to 2pm each day in Ballinaglera at Rynn's Pub.
However, parts of Galway and Clare are still experiencing significant disruption to water supplies.
In Sligo, night time restrictions will apply in the following areas: Ballymote, Coolaney, Ballinacarrow, Monasteraden, Gurteeen and Ballintogher.
The emergency water tanks and stand-pipes are currently being removed, but this facility will be kept under review over the coming days.
Limerick County Council is to shut off water supplies overnight at the following locations: Devon Rd to Tournafulla including Tournafulla Village; Devon Rd to Mountmahon; Rathcahill; Meenoline South, Caher Res including Killarney Road Abbeyfeale and Knocknasna Booster; Athea Area; Templeglantine Area; Ballagh Area; Hospital, Herbertstown, Galbally and Kilfinane may experience reduced water pressure and have water shut off this evening.
Meanwhile, Chief Executive of the Restaurants Association of Ireland Adrian Cummins is calling for a reduction in rates for its members.
Speaking on RTÉ's Morning Ireland, Mr Cummins said the water restrictions have meant that businesses that had already seen a cut in diners during the cold snap struggled to stay open due to the water restrictions.
The organisation is now seeking to hold an emergency meeting with Minister for Tourism Mary Hanafin.
The number of households in the Northern Ireland now without a water supply has fallen to less than 300, down from 1,000 last night.
Northern Ireland Water say under 10,000 properties will suffer a constrained supply this evening and overnight.
This represents a quarter of the supply restrictions imposed last night.
Demand for water is expected to peak tomorrow when shops offices and schools re-open after the long Christmas break.
