Is Dublin Tap Water Safe To Drink?
Yes! The tap water is safe to drink.
Yes, tap water in Dublin is generally safe to drink. It is treated and monitored under Ireland’s drinking water standards, with Dublin’s public supply typically meeting health requirements.
The main local concern is lead from older household plumbing, not the treated water itself. If a property has old pipes, run the cold tap briefly before drinking, especially after water has stood overnight.
