Irish Water says it is working to repair a burst watermain in Grange in north Sligo.
Homes and businesses in Newtown, Ardnaglass Lower, Grogagh, Pine Grove area, and parts of Aghagad South of Pine Grove estate are affected.
Some customers may be experiencing low water pressure and water outages.
It is expected that repairs will be completed by 4.30pm this afternoon but it may take 2-3 hours for normal supply to return as the network re-fills.
