Repairs to a burst water main may cause supply disruptions to Burt, Fahan, Newtowncunningham, Manorcunningham, Bridge End, Burnfoot and surrounding areas.
A traffic management plan will be in place for the duration of the works.
Works are scheduled to take place until 2am tomorrow.
It is recommended that those affected allow 3-4 hours after the estimated restoration time for supply to fully return.
