Donegal County Council says that the demand for water from the supply network today remains above normal.
Some areas, including Lifford and reservoirs at Tievebrack, Ballinacor and Gleneely (Castlefin) will have their outflows turned off tonight, and the council says supply may take some hours to reach all areas when turned on again.
In East Inishowen the situation has continued to improve at the Quigley's Point, Drumhaggart, Redcastle and Iskaheen reservoirs. This now enables general supply availability in these areas.
A burst watermain on the supply line from the Alt (near Castlefin) reservoir is causing further interruption of supply as repair works are ongoing throughout today.
The supply from this reservoir will be made available as soon as the repairs are carried out. This repair work is expected to be completed this evening (Jan 7th).
The council has urged the public to continue efforts to prevent water loss through leakage, running taps, bursts in unattended premises and in pipes to out buildings and fields.
