Water Source

Ljubljana’s water comes from groundwater pumped from the sand and gravel aquifers of Ljubljansko polje and Ljubljansko barje, via five pumping facilities. The naturally filtered source requires minimal treatment.

Contaminants & Concerns

No significant health concerns in current supply. Historical contamination of the Ljubljansko polje aquifer with nitrates and trace industrial solvents has been improving since 2010 and is now within EU limits.

Tips

  • Ljubljana is one of the few EU capitals where tap water needs essentially no chemical treatment — drink with confidence
  • Public drinking fountains throughout the old town and along the Ljubljanica River serve safe water
  • The water’s mineral profile gives it a pleasant, slightly sweet taste that many visitors comment on
