Water outages are expected in Craughwell, Loughrea, Clostoken, Cloonoo and surrounding areas tomorrow due to works being carried out on the network.
Irish Water said that people living in those areas may experience water outages during the day due to new connections works.
The works are scheduled to take place from 8am until 5pm on Thursday, March 19.
A traffic management plan will be in place where work is occurring for their duration.
It may take two to three hours after they are completed before affected customers have their full water supply restored.
