Water Cooler Rental vs. Buying Bottled Water: Business ROI

Modern organisations face a dual challenge: reducing operational costs while lowering their environmental footprint. The way drinking water is provided in the workplace plays an important role in achieving both goals.

Using bottled water and outdated bottled water coolers leads to unnecessary costs, additional logistics and avoidable waste. A modern, mains-fed water cooler offers a sustainable and efficient alternative that quickly pays for itself.

Renting a Water Cooler vs. Buying Bottled Water: A Direct Comparison

When businesses choose traditional bottled water, they often focus solely on the purchase price. However, that only tells part of the story.

Behind every delivery lies a range of hidden operational costs that continue to add up. By switching to a mains-fed drinking water system, you eliminate this entire supply chain and opt for a solution that is more efficient, sustainable and cost-effective.

The Hidden Costs of Traditional Bottled Water

When a business purchases bottled water, it often unknowingly incurs a range of indirect costs:

The logistics chain: Delivery costs from the supplier to your locations, including the CO₂ emissions generated by transportation.
The storage burden: Valuable warehouse or break room space permanently occupied by full and empty crates.
Lost productivity & hygiene: Employees and facility teams spend valuable time moving heavy crates and continuously restocking refrigerators, while open bottle systems also pose additional hygiene risks.

A centralised mains-fed drinking water solution filters and chills tap water on-site. This transforms an unpredictable stream of invoices and manual tasks into a fixed, transparent and predictable operating model.

The ROI of a Water Cooler in the Workplace

Choosing a mains-fed water cooler is about more than sustainability. It is also a smart investment that reduces your operating costs. While bottled water comes with recurring expenses for purchasing, transportation, storage and waste disposal, a fixed drinking water system provides a transparent and predictable solution.

You also save time and reduce the logistical workload in your office. Employees no longer need to move bottles or replenish supplies, while packaging waste is significantly reduced. The result is a more efficient workplace, a smaller environmental footprint and an investment that pays for itself over time.

Sustainability and Employer Branding in Practice: Two Case Studies

The benefits extend far beyond financial savings. Organisations that have implemented this transition on a large scale demonstrate that eliminating bottled water solves both logistical and environmental challenges.

Case Study 1: Randstad Achieves a 65% Reduction in Plastic Packaging Waste

At HR services provider Randstad, bottled water coolers and bottled water created unnecessary waste and added logistical complexity. By choosing AQUALEX's sustainable drinking water solutions, the company adopted a more efficient alternative that perfectly meets the mobility and flexibility needs of its extensive office network.

Christelle Mertz, Facilities Coordinator at Randstad, shares the results:

"The results at Randstad were almost immediate. We now reduce our plastic packaging waste by 65% each year, the equivalent of 600,000 plastic 500 ml bottles. That's not even mentioning the cost savings and the online access to service reports, which enable optimal facilities management. In addition to the technical and practical advantages, Randstad was also won over by the design of the drinking water systems, which integrate perfectly into the office environment."

Following a successful pilot in 2019, the systems have now been rolled out across more than 90 offices.

Case Study 2: Delen Private Bank Combines Logistical Efficiency with a Premium Brand Experience

In the world of private banking, brand image and quality go hand in hand. At Delen Private Bank, sustainability is also a core priority, reflected consistently in both renovation and new-build projects.

To structurally reduce waste and simplify logistics, the bank chose centralised mains-fed drinking water systems.

Evert Saladin, Logistics Facility Manager at Delen Private Bank, explains the operational rationale:

"To reduce our waste, we wanted to eliminate the use of PET and glass bottles, which created unnecessary waste and transport. We installed several taps providing still and sparkling water in the staff restaurant as well as in all kitchenettes serving our meeting rooms. From now on, every new office will be equipped with AQUALEX systems. From a logistical perspective, a mains-fed drinking water system is far more efficient than bottled water."

In addition to reducing the logistical burden, the solution reinforces the family-owned bank's visual identity. Anne-Sophie Delen, Head of Marketing, adds:

"We have always considered it important to create a pleasant working environment. Our clients truly appreciate the result. And the personalised Delen Private Bank bottles complete the brand experience."

TIP

Run a One-Week Bottled Water Audit in Your Organisation

Want to understand the real, often hidden cost of your current drinking water policy? During one representative working week, count how many bottles and pieces of packaging actually pass through your workplace, break areas and waste bins. Then multiply that weekly consumption by the number of weeks your organisation operates each year. You'll gain an immediate, clear picture of your annual waste volume and the number of hours your team spends on low-value logistical tasks.

Conclusion: Making the Right Choice for Your Organisation

Continuing to purchase bottled water or manually restock refrigerators is an outdated approach from both an operational and environmental perspective.

Switching to a modern drinking water system delivers clear value in three key areas:

Financial: Variable and unpredictable costs are replaced by a fixed, transparent and cost-effective rental model with a fast and measurable return on investment.
Logistics: Immediate time savings for your facilities team, online access to service reports, and additional storage space made available.
Employer Branding & Well-being: A healthy, hygienic and sustainable workplace that enhances employee satisfaction while strengthening your organisation’s reputation with clients.
