Castletown/Ballyagran Water Supply Judged 'Potentially Unsafe'

The Castletown/Ballyagran Public Water Supply in County Limerick has been placed on a Boil Water Notice with immediate effect after it was judged potentially unsafe to drink.

This decision was made by Irish Water and Limerick City and County Council following consultation with the Health Service Executive (HSE). The water was called potentially unsafe to drink due to inadequate disinfection because of UV treatment breakdown, affecting a population of 1,204.

Customers can also check if they are impacted by this Boil Water Notice by visiting the Water Quality section of the Irish Water website and entering their property's Eircode in the search bar. 


Drinking water experts from Irish Water and Limerick City and County Council are working to implement solutions to lift the notice as quickly and as safely as possible in consultation with the HSE. In the meantime, all customers on this supply are advised to boil and cool their water before use until further notice. 

Irish Water's Duane O'Brien said: "Public health is Irish Water's number one priority and we are working closely with Limerick City and County Council to restore drinking water quality for all impacted customers and to lift the Boil Water Notice as quickly as it is safe to do so, and in consultation with the HSE. We regret the impact that this BWN will have on the local community and would like to assure them that we are prioritising works to restore a safe water supply with a view of lifting the notice as soon as it is safe to do so."

Vulnerable customers who have registered with Irish Water will receive direct communication on this Boil Water Notice and are reminded that the water is safe to consume once boiled and cooled. In line with HSE advice on hand washing, Irish Water advises that the water remains suitable for this purpose and boiling the water is not required.
