Irish Water & Mayo County Council

Date: Tuesday 04th of December 2018

Irish Water and Mayo County Council wishes to notify all customers on the Ballycastle Public Water Supply and consumers on the Corrower/Sea Road and Lisbrin group water schemes which are served from the Ballycastle supply, that after consultation with the Health Service Executive, that the boil water notice imposed on the supply on the 12th of October 2018, is now lifted with immediate effect.

A map of the Ballycastle scheme, detailing the areas where this BWN lift notice applies, is available on and

Lift Areas: All persons served by the Ballycastle Public Water Scheme and the following Group Water Schemes: Corrower/Sea Road GWS and Lisbrin GWS.

The level of treatment provided at the Ballycastle Water Treatment Plant does not provide adequate protection against Cryptosporidium. Irish Water and Mayo County Council are advising customers that in the absence of a validated cryptosporidium barrier that there is a risk of further Cryptosporidium detections in the supply. If this scenario occurs, it is possible that the boil water notice may be re-imposed and remain in place until the scheme is connected to the Ballina-Lisglennon public water supply. Irish Water will continue to monitor this supply closely for the presence of Cryptosporidium in the interest of public health and will liaise with the HSE on a regular basis.

Irish Water and Mayo County Council confirm that customers can now resume normal use of the water supply for drinking, food preparation and brushing teeth.

The Irish Water Customer Contact Centre (1850 278 278) is available to answer customer queries in relation to this water notice. Further information is available on the Irish Water website at

Irish Water and Mayo County Council acknowledge the patience, cooperation and assistance of the general public during the period of the boil water notice and greatly regrets any inconvenience caused to householders, the farming and business community.
