Can I Drink Tap Water in Dublin?

Dublin tap water is generally safe for drinking, brushing teeth, and ice, and Ireland publishes water quality oversight and utility information. Travelers usually do not need bottled water for health reasons, but checking local advisories is sensible because occasional boil-water notices can occur in specific supply zones. Older property plumbing is the main practical caveat.

Dublin is served by Uisce Eireann (Irish Water), which provides consumer information about water quality and local water notices, while EPA Ireland provides national drinking-water compliance oversight. This supports a generally safe rating for travelers under normal conditions. In most hotels and restaurants in Dublin, tap water is suitable for drinking, brushing teeth, and ice. The main traveler caveats are local and building-specific: temporary boil-water notices in particular zones, maintenance-related water quality changes, and older internal plumbing that may affect taste or increase lead risk. For most short stays, simply checking utility notices and flushing cold water in older properties is enough. A filter is optional and mostly useful for taste or extra reassurance.

Dublin is generally a low-risk tap-water city for travelers, and most visitors can use tap water for drinking, ice, and brushing teeth. The best precaution is practical: check local utility notices and be a little more careful in older buildings by flushing the tap and using a filter if you want extra reassurance.
