Water Source

HOFOR (Greater Copenhagen Utility) extracts water from deep limestone aquifers surrounding the city. The groundwater is naturally filtered through centuries-old geological layers, requiring only minimal aeration and sand filtration before distribution.

Contaminants & Concerns

No significant health concerns. The deep aquifer source is naturally protected from surface contamination, and the water meets all EU standards without chlorination.

Tips

  • Copenhagen tap water is unchlorinated, giving it a clean, neutral taste
  • No need to buy bottled water anywhere in the city
  • The water is hard due to limestone geology — a filter can help with limescale on kettles and appliances
