Cavan County Council has issued a boil water notice for the Corlough Group Water Scheme after samples taken on 14 October 2026 revealed the presence of coliform and E.coli bacteria. Acting on advice from the Health Service Executive, this precautionary measure aims to protect consumers from the risk of waterborne illness.
Residents are instructed to boil water vigorously for at least 10 minutes before using it for drinking, preparing salads or uncooked foods, brushing teeth, or making ice. Boiled water should be cooled, covered, and stored in a refrigerator or cold place. Special care is advised when preparing infant feeds: tap water must be boiled once and cooled, and bottled water used should have sodium content below 200mg/l to avoid health complications.
Unboiled water may still be used for personal hygiene, bathing, and flushing toilets, but not for brushing teeth or gargling. The council warns that domestic water filters and hot tap water do not make water safe to consume. Ice cubes and filtered water in fridges should be discarded, and children should be supervised to prevent swallowing bath water. Those most vulnerable include young children, elderly people, and individuals with weakened immune systems. The council will continue working with the HSE and keep residents informed by letter and email regarding the lifting of the notice. Queries can be directed to [email protected].
