Key Statistics
Water Infrastructure & Supply
Denmark has one of the most advanced and well-maintained water supply systems in Europe. The country relies almost exclusively on groundwater extracted from aquifers, which is naturally filtered through layers of sand and limestone. This approach has been in place for over a century, and the Danish model is distinctive because the water requires very little chemical treatment , most Danish tap water is not chlorinated, unlike in many other developed countries.
The water supply is managed by approximately 2,600 waterworks, ranging from large municipal utilities like HOFOR (Greater Copenhagen Utility) to small local cooperatives. Water undergoes simple aeration and sand filtration to remove iron and manganese before distribution. Denmark has invested heavily in protecting groundwater catchment areas, and since 1987 the government has designated drinking water protection zones around wells to prevent contamination from agriculture and industry.
Ongoing challenges include dealing with pesticide residues and PFAS (per- and polyfluoroalkyl substances) detected in some groundwater sources. The Danish government has committed billions of Danish kroner to remediation and monitoring programs. A national action plan launched in the early 2020s focuses on closing contaminated wells, finding new clean sources, and upgrading distribution networks. Denmark also leads Europe in reducing water loss from pipes, with leakage rates below 8%.
Contamination & Health Risks
Tap water in Denmark poses virtually no health risk to travelers. The water consistently meets or exceeds all EU Drinking Water Directive standards and Danish national quality requirements. Microbiological contamination events are extremely rare and are dealt with swiftly through boil-water advisories when they do occur, typically affecting only small local waterworks.
The primary long-term concerns in Denmark relate to agricultural chemicals. Residues of pesticides, including some that were banned decades ago, have been detected in certain groundwater sources, though almost always at levels well below health thresholds. PFAS contamination from firefighting foam and industrial sites has also been identified at some locations, prompting closures of affected wells. For short-term visitors, these trace contaminants pose no meaningful risk.
Travelers with compromised immune systems or very young children can drink Danish tap water with full confidence. There is no need for boiling, filtering, or purchasing bottled water for health reasons. In the rare event of a contamination incident, local authorities communicate advisories quickly through media and apps. Denmark's water quality monitoring is among the most rigorous in the world, with thousands of samples tested annually.
Regional Water Quality Breakdown
Copenhagen
safeCopenhagen's water is supplied by HOFOR and sourced from well-protected groundwater. The water is unchlorinated, soft to moderately hard, and consistently ranks among the best in Europe. Tap water throughout the capital is excellent for drinking.
Aarhus
safeAarhus Vand supplies high-quality groundwater-based tap water to Denmark's second-largest city. The water meets all EU and national standards with no chlorination required. Visitors can drink tap water from any source in the city with complete confidence.
Odense
safeOdense's tap water, managed by VandCenter Syd, is sourced from local groundwater aquifers. The water is clean and safe, though slightly harder in mineral content than in some other Danish cities. It is perfectly safe for all uses.
Aalborg
safeAalborg Forsyning delivers safe, clean tap water throughout northern Jutland's largest city. The groundwater-based supply meets all quality standards. Some areas have relatively hard water, which is harmless but can leave mineral deposits on fixtures.
Bornholm
safeThis popular island destination has its own local waterworks supplying groundwater-based tap water. Water quality is consistently good, though the island's smaller waterworks are occasionally subject to more frequent testing due to their size. Tap water is safe to drink across the island.
Rural Jutland
safeEven small towns and rural areas across Jutland have safe drinking water, supplied by local cooperative waterworks. Some agricultural areas have seen elevated nitrate levels in groundwater, but affected sources are monitored and taken offline when necessary. Tap water remains safe throughout the region.
Practical Tips for Travelers
- Carry a reusable water bottle , Danish tap water is excellent everywhere, and many cities have public refill stations and drinking fountains.
- At restaurants, ask for 'postevand' (tap water) which is usually served free of charge, saving you the cost of bottled water.
- Danish tap water is not chlorinated in most areas, so it may taste noticeably cleaner and softer than what you're used to at home.
- If your accommodation has very old plumbing, let the cold water run for 10, 15 seconds before drinking to flush any standing water from pipes.
- Don't waste money on bottled water for health reasons , there is absolutely no safety advantage to bottled water over tap water in Denmark.
- Take advantage of Denmark's bottle deposit system ('pant') , return empty bottles and cans to supermarket machines to reclaim your deposit.
- In Danish, you can say 'Kan jeg f et glas vand?' (Can I have a glass of water?) at any caf or restaurant to request free tap water.
- Check the local utility's website or app for real-time water quality data , major suppliers like HOFOR and Aarhus Vand publish detailed reports online.
Bottled Water Availability & Cost
Bottled water is widely available in Denmark at supermarkets, convenience stores, and restaurants, though it is relatively expensive compared to many countries. A 0.5-liter bottle typically costs 15, 25 DKK (approximately 2, 3.50 or $2.20, 3.80 USD) in a shop, while a 1.5-liter bottle runs about 10, 20 DKK in supermarkets. In restaurants and cafs, a bottle of water can cost 30, 60 DKK. Popular brands include Aqua d'Or, Kildevld, and the Danish sparkling water brand Egekilde.
Given the exceptional quality of Danish tap water, buying bottled water is largely unnecessary and not environmentally recommended. Many restaurants will happily serve free tap water if you ask, and refilling a reusable bottle at any tap is perfectly safe. Denmark has an efficient bottle deposit system (pant) that encourages recycling , you pay a small deposit on bottles which is refunded when returned to machines at supermarkets. For budget-conscious and eco-minded travelers, carrying a reusable bottle is the smartest choice.
Frequently Asked Questions
Can I brush my teeth with tap water in Denmark?

Why is Danish tap water not chlorinated?
Denmark relies on deep groundwater that is naturally filtered through geological layers, making it very clean. Simple aeration and sand filtration are sufficient to make it drinkable, so chlorine disinfection is generally not needed. This gives Danish water a notably fresh, clean taste.
Is tap water on the Danish islands (Bornholm, Funen) safe?
Yes, tap water on all Danish islands is safe to drink. Each island has its own local waterworks that draw from groundwater and meet the same strict national quality standards as mainland Denmark.
