Is chlorine added to tap water in Denmark?
Simple treatment without chlorine
Short answer
No, Danish tap water is normally not disinfected with chlorine, which many other countries have to do. Because the water is groundwater, it usually needs only aeration and filtration. In Copenhagen the water is aerated and run through sand filters that remove hydrogen sulphide, methane, iron and manganese. Some waterworks, for example in Brøndby, also use UV light as an extra safety step.
Why
- Groundwater is cleaner than surface water from the start.
- Aeration and sand filters do most of the work.
- UV light is an extra step at some plants, not chlorine.
Details
Waterworks that soften the water remove lime with small pellets before aeration.
Tip
If you want water without added substances, the tap is the simple choice in Denmark.
What may differ
Treatment steps can differ between waterworks and change when plants are upgraded.
Common misconception
Many visitors assume all tap water in Europe is chlorinated.
What actually happens
Danish groundwater normally reaches the tap without chlorine.
