Irish Water says it has now completed repairs to a section of a burst watermain in Bundoran.
A large number of households and businesses in the West end of Bundoran had been left without water over the course of the weekend.
Irish Water, working in partnership with Donegal County Council, says it has completed repairs to a section of water main that burst in Bundoran on Sunday night.
The repairs were finished at about 12.30pm today.
However, Irish Water says it may take several hours for full water supply to return to customers in higher lying areas.
This is the second time a burst has occurred on this pipe in a number of days.
A previous burst occurred on Friday and repairs were completed by Saturday morning.
About 500 customers were affected by the outage and Irish Water has apologised to all businesses and residents affected.
Irish Water says its Customer Care team is available 24/7 on 1850 278 278 or customers can visit its Supply and Service section on water.ie for updates.
Irish Water also says that due to the frequency of bursts on this pipe, it will be replacing approximately 1.4 kilometres of water main in Bundoran.
These works are due to commence in September, once the busy tourist season is over and are due to take eight weeks to complete.
These works are part of the Donegal Countywide Water Main Rehabilitation Project which sees Irish Water, in partnership with Donegal County Council, investing €12 million in the replacement and rehabilitation of approximately 40 kilometres of old water mains across the county.
