Can You Drink Tap Water in the Czech Republic?

Tap water in the Czech Republic is safe to drink in Prague, Brno, Ostrava, and throughout the country, meeting European Union water quality standards. Czech tap water is treated to EU requirements and is safe for consumption in cities, towns, and most rural areas. Many Czechs drink tap water regularly and visitors can do the same confidently. Prague's tap water comes from several sources including Želivka reservoir and Káraný waterworks, undergoes comprehensive treatment, and meets all safety standards. Prague's water is considered good quality despite some older buildings having aging pipes that may affect taste.

Infrastructure has improved significantly since EU accession. Brno, the second city, has safe tap water from protected reservoir sources with good treatment. Ostrava and Moravia region have tap water meeting EU standards. Throughout the Czech Republic including spa towns like Karlovy Vary (Carlsbad), Mariánské Lázně, and tourist areas, tap water is safe.

These spa towns are famous for mineral water springs which are separate from tap water but tap water is also safe. The Bohemian countryside, castles, and rural areas generally have safe tap water though some small villages rely on well water that should be verified. Throughout the Czech Republic, tap water can be used for drinking, brushing teeth, making ice, and cooking. Czech restaurants do not typically serve free tap water as cultural practice involves ordering beverages, but tap water is safe if requested. Many Czechs prefer bottled water or beer (pivo) with meals.

Despite safe tap water, bottled water remains popular for cultural reasons.
