Is Tap Water Safe to Drink in Bosnia and Herzegovina?

Bosnia and Herzegovina is rich in water resources. Sarajevo's supply comes from karst springs at Bacevo and Tilava and the Bosna River headwaters, treated at modern plants. Banja Luka draws from the Vrbas River. The country's mountainous terrain provides abundant spring water, but infrastructure investment varies between the two governing entities (Federation and Republika Srpska).

Municipal water in major cities meets WHO guidelines, but aging pipes in older buildings can leach iron and occasionally lead. Some rural systems lack consistent chlorination. Post-war reconstruction improved urban infrastructure significantly, but smaller communities still have gaps.

Safest in Sarajevo, Banja Luka, Tuzla, and Mostar, where water utilities have been modernized with international assistance. Smaller towns and rural villages, particularly in remote mountain areas, may rely on local springs or wells without regular testing.

Moderate to hard, typically 150–350 mg/L, due to the predominant karst limestone geology that characterizes much of the Dinaric Alps region..

Yes, in Sarajevo and other cities, locals drink tap water regularly and consider the spring-fed supply to be good quality. In rural areas, many households use their own spring sources.

• •In Mostar and Herzegovina, tap water is safe in the town center but consider bottled water in outlying areas
• •When hiking, do not assume mountain streams are safe without local confirmation
• •Bottled water is cheap and available everywhere as a backup

• •Use bottled or filtered water in rural areas and small towns with older infrastructure
• •In older buildings, let the tap run briefly before drinking
