It's in relation to upgrade works which started yesterday.
Water outages can be expected in parts of Westmeath today.
Old, cast-irons mains are being replaced in the Ballinea area of Mullingar, to strengthen the local water network.
Irish Water is advising customers that low supply and outages are possible, as a result, between 9am and 4pm.
