5 Year Cost Analysis for Instant Filtered Water vs Bottled Water Coolers

Choosing the right water solution for your workplace can appear straightforward, until the long-term costs, operational efficiencies, and environmental trade-offs become evident.

For many New Zealand businesses, bottled water coolers are a familiar fixture. They seem convenient, require no installation, and the upfront cost is minimal. However, this perceived simplicity can obscure years of unnecessary expense, logistical complexity, and avoidable waste.

We’ve examined the five-year cost of bottled water coolers compared to Billi’s instant filtered water systems. It provides the facts needed by facilities managers, architects, and procurement leads to make future-focused decisions.

 

Why Bottled Water Coolers Are Still Commonplace

Bottled water coolers are widely used because they appear to offer flexibility and ease:

  • No plumbing required
  • Straightforward rental plans
  • Basic maintenance handled by suppliers
  • Costs are incremental and seem manageable

 

This simplicity, however, comes at a cost that accumulates.

 

Hidden Cost of Bottled Water Coolers

Behind the convenience of bottled water coolers are a series of operational and financial costs:

  • Recurring rental or lease fees
  • Per-litre charges for delivered bottles
  • Storage space required for both full and empty containers
  • Manual handling risks and health & safety considerations
  • Service interruptions due to delivery delays or stock shortages
  • Significant environmental impact from single-use plastics and transport

 

Take a typical 30-person workplace. If it consumes three 15-litre bottles per week, that’s approximately 2,340 litres annually. At an average cost of $1.20 per litre (factoring in delivery and service fees), the business is spending about $2,800 each year. Over five years, this adds up to more than $14,000, not including the indirect costs (such as rental fees or environmental waste).

 

How Instant Filtered Systems from Billi Work

Our systems provide instant filtered chilled, boiling, and sparkling water directly from the mains supply, eliminating the need for plastic bottles or frequent deliveries.

Key features include:

  • Underbench installation with minimal spatial footprint
  • No joinery or ventilation modifications required
  • Energy-saving technologies, including standby modes and heat exchange systems
  • High-capacity output (e.g. Quadra 440 can deliver dozens of filtered boiling & chilled litres per hour)
  • Digital safety and hygiene controls, including lockouts and filter alerts
  • Predictable servicing through BilliCare service plans*

 

*BilliCare maintenance is handled by accredited technicians, ensuring hygiene, performance, and peace of mind without involving your internal staff.

 

Five-Year Cost Comparison

Cost Category Bottled Water Cooler Billi Instant Filtered System
Equipment Purchase + Installation Included in rental ~$5,000 to purchase a Billi + <$500 installation
Annual Water Supply >$2,800 (including delivery and service fees) N/A (connected to mains water)
Servicing & Maintenance Included in rental <$1,000 per year (the Billi Blue Bi-Annual Service Plan)
CO2 & Filter Replacement N/A ~$160 per CO2 Replacement Cylinder (if applicable)
Energy Consumption Moderate to high Low (standby and reclaim tech)
Plastic Waste High (hundreds of bottles annually) None
Emissions Impact High (transport reliant) Low (no delivery, efficient tech)

Total Estimated Cost Over 5 Years

  • Bottled Water Cooler: >$14,000
  • Billi System: >$10,500*

 

*price varies depending on the chosen Billi system, exclusion of CO2 replacement cylinders, and the exclusion of mains water supply costs.

 

Responding to Common Concerns

 

The upfront cost is hard to justify.

True, the initial cost for a Billi system is higher. But most organisations reach break-even within a few years (certainly within five years) and savings increase annually thereafter.

We don’t want to manage another appliance.

BilliCare exists to prevent that. Filter changes, hygiene maintenance, and system optimisation are all handled by trained technicians.

What if we move premises or restructure?

Billi systems are relocatable and modular. They can adapt as your workspace does, and installation requires no permanent alterations.

 

Sustainability Case Is Stronger Than Ever

Environmental responsibility is now expected from New Zealand businesses, and is not an optional extra. Billi systems are designed to support:

  • Global GreenTag certification
  • WELL Building Standard compliance
  • Reduced energy use through standby and heat recovery
  • Zero single-use plastic
  • Low transport emissions due to onsite generation

 

Organisations serious about their ESG targets are increasingly viewing hydration as part of their overall footprint, just like lighting, energy, and waste. Learn more about our sustainability commitments.

 

Make the Smarter Long-Term Investment

Bottled water coolers may feel familiar, but they don’t stand up to Billi systems over five years. The hidden expenses, operational hassles, and environmental costs are substantial.

Billi systems provide a cleaner, more efficient, and future-proof alternative. They can reduce costs, simplify operations, and demonstrate a clear commitment to sustainability, all while providing a better user experience. Your next step is to:
