Can you drink the tap water in Ireland?

The US Center for Disease Control’s travel advisory confirms the safety of the tap water in Ireland (source). However, it would be best if you take special precautions toward the unregulated water sources in some areas. Like all countries though, water accessibility, sanitation, and treatment vary widely from location to location, so we encourage looking for specific city information.

What do people in Ireland think about the tap water?

The Irish have traditionally always drunk tap water, but in recent years have introduced filter systems to combat the presence of potentially toxic chemicals called trihalomethanes (THMs) in the water supply, which have exceeded EU-sanctioned levels in various parts of the country, including Kerry, Cork, Kilkenny City, Waterford, Wicklow, Meath, Mayo, Roscommon, Donegal and Galway. Although the potential issues are only associated with long-term exposures to THMs, you should make sure to drink only filtered or bottled water while in Ireland, and never drink from the bathroom tap.

What Do People In Ireland Think About The Tap Water?

Travelers and residents of Ireland have rated the water quality and pollution as follows, according to subjective survey data. A score of 100% is considered very high, and a score of 0% is very low. Please be cautious that "moderate to very high" water pollution is bad and the higher the rate of water quality the better.


Always take extra precautions, the water may be safe to drink when it leaves the sewage treatment plant but it may pick up pollutants during its way to your tap. We advise that you ask locals or hotel staff about the water quality. Also, note that different cities have different water mineral contents.
