Natural spring water
Identified groundwater, collected at the spring, without chemical disinfection. Bottled at the source. Stable mineral composition. Regulated under Directive 2009/54/EC.
Spring Water vs. Tap Water: A Comprehensive Comparison to Help You Make the Right Choice
Our Water
There are two approaches: natural spring water (in bottles) and filtered tap water (from a connected water dispenser). Both are safe, comply with European standards, and are suitable for different uses. This unbiased, fact-based page will help you make a choice, whether it leads you to one or the other.
What exactly are we talking about?
Definitions
-
-
Natural mineral water
A subcategory of spring water, with a mineral composition whose beneficial properties have been recognized by experts. Évian, Vittel, and Spa are examples of this type.
-
Tap water
Supplied through the public water system. In Luxembourg, it comes from groundwater and surface water and is treated by chlorination. Complies with EU Directive 2020/2184.
-
Filtered tap water
Municipal water that has undergone multi-stage filtration (activated carbon, microfiltration) at the point of use. Removes chlorine and particles without substantially altering the mineral content.
The 8 Criteria That Matter
Comparison
| Criterion | Spring water (bottled) | Filtered tap water |
|---|---|---|
| Origin | Underground spring identified | A mix of groundwater and surface water |
| Treatment | None (except for possible microfiltration) | Chlorination + point-of-use filtration |
| Mineral Composition | Stable, identifiable, guaranteed | Varies by municipality |
| Taste | Described by the source as “more natural” | Neutral after filtration, chlorine-free |
| Logistics | Regular deliveries of gas cylinders | None (continuously connected) |
| Monthly cost (20 people) | ~80–150 € | ~70–120 € |
| Carbon Footprint | Moderate (transport of gas cylinders) | Low (no logistics) |
| Ideal for | Premium image, home page, no plumbing required | Campsites > 20 people, heavy use |
Estimates based on the Luxembourg B2B market; adjust according to the actual configuration.
Good Use Cases for the Gas Cylinder
Choosing Spring Water
✓ You’re setting up a premium reception or lobby area
✓ You don’t have access to a water supply (isolated floor, mezzanine)
✓ You’re setting up a medical waiting room or office
✓ You’re setting up a temporary space (event, construction site, trade show)
✓ You want to get started quickly without a technical visit
Good Use Cases for the Network Fountain
Select the filtered network
✓ You’re equipping a site with more than 20 people
✓ You have an ambitious CSR initiative (reduced carbon footprint)
✓ You’re equipping an environment with high energy consumption (workshop, school, sports facility)
✓ You have access to a water supply (kitchen, water source)
✓ You’re looking for the most cost-effective monthly rate over the long term
What if we combined the two?
Mixed Option
Many of our customers use both solutions at the same time:
✓ Mains-connected water cooler in the break room/cafeteria (capacity, cost savings)
✓ Spring water cooler with a water bottle at the reception desk or in the client meeting room (image, taste)
This is often what our site selection study recommends for medium- or large-sized sites.
Three Common Myths to Dispel
Common Misconceptions
-
"Spring water is healthier"
Not necessarily. The microbiological safety of both is guaranteed by standards. The difference lies in taste, traceability, and stable mineral composition—not in overall “health.”
-
"Tap water contains hormones"
Media fears are greatly exaggerated. EU regulations are strict. Filtration provides additional safety, not a “purification” of massive pollution.
-
"Filtered water no longer contains any minerals."
False. Standard filtration removes chlorine and particles without substantially altering the mineral content. The result is water with a neutral taste, which is viewed positively.
Your Questions About Choosing
Frequently Asked Questions
-
Does spring water contain more minerals than filtered water?
Not necessarily; it depends on the source. Some spring waters are low in minerals. Filtered tap water retains the mineral content of the local water supply. For daily consumption, low-mineral-content waters are generally recommended.
-
Which one is more environmentally friendly?
A mains-connected water dispenser generally has a lower carbon footprint (no logistics involved with water bottles). But our water bottles can be reused for 70 cycles, which significantly narrows the gap. For a large facility: mains-connected. For a small space without plumbing: water bottles—no guilt—it’s better than buying packs at the supermarket.
-
Can we try it out before we decide?
Yes. Upon request, we offer a trial period for certain configurations. You can also organize a taste test during a meeting (spring water vs. filtered water vs. tap water) to get a group opinion.
-
How is it different from bottled water from the supermarket?
Quality (our water comes from an identified, monitored source), cost (€0.50 to €1 per liter at the supermarket vs. less than €0.15 per jug), and plastic footprint (single-use vs. jugs that can be reused 70 times).
We'll help you choose—without any bias.
