Restrictions will occur between 10 o'clock tonight and six tomorrow morning.
Irish Water is advising customers in Westmeath of an interruption to their service tonight.
This is due to repair works being carried out on a mechanical issue at the treatment plant.
The restriction will be in place from 10pm, Tuesday 26 October, until 6am tomorrow which will impact customers in Athlone Town, Baylin, Mount Temple, The Ories, Garrycastle, Dublin Road, Ardnaglug, Fardrum, Moydrum, Blyry, Killyon Hill, Bonavalley and surrounding areas.
Typically it takes two to three hours following essential works for normal supply to restore to all customers.
John Gavin, Regional Operations Lead with Irish Water said, “This restriction is necessary to safeguard daytime water supply for all homes and business in Athlone and surrounding areas. Repairs are being conducted as quickly and as efficiently as possible at the water treatment plant. Irish Water understands the inconvenience night-time restrictions can have on customers and it appreciates customers’ patience as we work to complete the repairs and restore normal water supply to all customers.”
