As a result of disinfection systems being compromised and reduced levels of Chlorine in some supplies, Boil Water Notices are being imposed on the following schemes with immediate effect as a precautionary measure:

Ballyknock

Kilcooney

Comeragh

Carrigeen

Ballyguiry

Grallagh

Customers supplied by these schemes should boil their water before use for drinking, preparing drinks made with water, preparation of salads and similar foods which are not cooked prior to eating, brushing of teeth and making of ice.

In addition, Irish Water customers in some parts of the county may begin to experience disruptions to their water supply this evening and into tomorrow (Friday).
