Source of Water in Prague, Czechia

Prague’s tap water comes mainly from the Želivka and Káraný water sources. Želivka supplies treated surface water from the Švihov Reservoir, while Káraný provides groundwater and naturally filtered water from the Jizera River area.

The Podolí Water Treatment Plant can also treat water from the Vltava River. It serves as a supplementary and reserve source for Prague’s water supply.

Prague Drinking Fountains

Public drinking fountains in Prague are generally safe to use when they are clearly marked as drinking-water fountains and are operating normally. The water comes from the public supply, which is regulated under Czech and European Union drinking-water standards.

Do not drink from decorative fountains, and follow any signs stating that water is not intended for consumption. During hot weather, let the water run briefly before drinking, especially if the fountain has not been used recently.
