Uisce Éireann have confirmed that water supply is being restored to customers on the stretch between Keshcarrigan and Ballinamore.
Repairs were carried out earlier today.
Customers in Castlefore, Drumlitten, Foxfield, Fenagh, Edentinny, Ardrum were all impacted.
While service has returned to many areas, it may take several hours for normal supply to fully restored to other areas.
Homes on higher ground and at the end of the network could experience longer delays before water pressure returns to normal.
