FOR HOME FOR COMMERCIAL

Sourcing equipment for federal, state, and defence infrastructure requires strict adherence to Australian Industry Capability policy frameworks. Decisions across public sector assets should prioritise supply chain resilience, transparent quality management, and guaranteed access to long-term technical support. Imported appliances introduce vulnerability to global shipping disruptions, prolonged lead times for spare parts, and inconsistent manufacturing standards.

Specifying Australian-made commercial water dispensers designed and manufactured in Melbourne ensures alignment with sovereign procurement objectives. Operating under ISO 9001 Quality Management certification under Certificate QEC11627, Billi Australia maintains strict control over every stage of production, engineering, and testing. Our manufacturing capability ensures short lead times, reliable project delivery schedules, and direct access to local engineering support for government fitouts, civic facilities, and defence base upgrades.

Meeting Environmental Ratings with GreenTag Gold and Energy Reclaim Engineering

Government buildings and defence infrastructure are subject to environmental performance mandates, including Green Star, NABERS, and WELL Building Standard performance targets. Procurement officers seeking a WELL building compliant water dispenser require verifiable third-party environmental credentials to satisfy institutional sustainability reporting frameworks (International WELL Building Institute).

To support these sustainability frameworks, our commercial underbench systems feature comprehensive environmental accreditation. Importantly, the Billi Quadra range holds Global GreenTag Gold Level Certification under LCARate standard 4.0, providing independent verification of low embodied impact and sustainable lifecycle performance. 

Furthermore, as an International WELL Building Institute Cornerstone Member, we design systems that align with indoor environmental quality criteria. These environmental ratings are driven by our patented thermodynamic heat exchange technology, which captures waste heat energy generated during the water chilling process and repurposes it to preheat incoming water for the boiling tank. This innovative energy-reclaim process significantly lowers building energy consumption, supporting public sector net-zero goals.

Maximising Floor Space Without Disruptive Cabinet Modifications

Commercial office space within government and defence departments demands maximum efficiency and clean architectural integration. Traditional underbench drinking water systems often require extensive cabinet ventilation grilles or door cutouts to disperse heat, compromising joinery aesthetics, increasing installation costs, and creating potential acoustic distractions in secure meeting areas.

We address these design constraints through advanced water-cooled technology that eliminates the need for cupboard ventilation cutouts or door grilles. With a compact underbench footprint requiring minimal cabinet space, our underbench systems allow facility planners to optimise storage and joinery design across administrative offices, briefing rooms, and secure zones. Operating quietly without cabinet fan noise, our systems maintain a quiet indoor environment essential for high-security government facilities.

Matching Specific System Capabilities to Facility Requirements

Public sector facilities encompass a wide array of operational zones, ranging from high-traffic staff cafeterias and public amenities to executive suites and secure meeting rooms. Selecting the appropriate government procurement drinking water systems requires matching specific system capacities to local usage patterns.

For high-volume staff breakout spaces, our high-capacity Billi Quadra and Billi OmniOne Pro deliver continuous boiling, chilled, and sparkling water from a single underbench unit. 

In executive suites and boardroom facilities, specifying a Multifunction Mixer Tap provides an all-in-one fixture delivering boiling, chilled, sparkling, plus domestic hot and cold water from a single spout. 

For public amenities and shared facilities, our sensor-operated touchless XT motion range ensures hygiene, reducing physical contact points while delivering reliable water filtration.

Operational Integrity and Security Compliance with BilliCare

Long-term asset management in public sector buildings requires dependable maintenance schedules that guarantee water quality, equipment reliability, and regulatory compliance. All our commercial water dispensers hold full WaterMark licensing under WM-21525 and WM-21882, alongside HACCP International Food Safety Certification under PE-972-WAT-1-02, verifying that water contact components meet stringent public health standards.

To ensure ongoing compliance in restricted-access or high-security facilities, we provide structured BilliCare service plans. Through our BilliCare plans, facilities receive automated, scheduled preventative maintenance from security-checked, accredited technicians. This all-inclusive service covers regular filter replacements to reduce sediment, chlorine, taste, and odour, as well as system flushes and performance checks. Establishing a fixed-rate maintenance framework ensures continuous operational integrity for secure facility underbench water systems without creating administrative burdens for facility managers.

To discuss specification requirements for your next project, you can contact our commercial procurement team or explore commercial solutions for government facilities. 

Specifiers, architects, and hydraulic engineers can also download BIM files or technical specifications to streamline tender documentation.

Managing water infrastructure across primary, secondary, and tertiary campuses requires balancing high peak demand with strict health, safety, and operational standards. During short recess and lunch breaks, hundreds of students gather at hydration points simultaneously, placing strain on conventional drinking fountains. In staff rooms, lecture halls, and administrative hubs, staff and visitor facilities often require continuous access to boiling and chilled drinking water without compromising safety or building energy efficiency.

To maintain water quality and operational hygiene across campus facilities, modern hydration points should adhere to food safety and public health frameworks, under certification PE-972-WAT-1-02. 

For over 30 years, Billi Australia has specified systems designed and manufactured in Melbourne, supporting compliance with Australian national plumbing codes through WaterMark licences WM-21525 and WM-21882.

Upgrading aging school infrastructure with modern commercial water dispensers resolves traditional bottlenecks while promoting student health and hydration.

Safety Engineering for Staff Rooms and Student Hubs

In educational environments, installing boiling water appliances introduces potential safety concerns regarding scalding or accidental discharge. Conventional urns and uninsulated taps carry inherent risks, particularly in busy staff kitchens, food technology classrooms, or university breakout spaces where staff and students interact.

Modern underbench tapware addresses these concerns through integrated electronic safety engineering. Billi commercial dispensers feature a safety switch that requires an intentional double-touch or hold command to activate boiling water, automatically locking after a period of non-use. To eliminate splashing and thermal shock, patented electronic flow controls ensure a smooth, splash-free stream of boiling water. 

Additionally, the tap body is constructed with cool-to-touch housing, ensuring the exterior surface remains safe to handle even during extended usage cycles. For student-accessible areas, systems can also be configured to isolate boiling functions entirely, delivering chilled and filtered ambient water.

Inclusive Access Across Campuses

Creating an inclusive educational environment requires specifying fixtures that cater to students and staff with diverse physical abilities. Under accessibility regulations and the Australian Standard for Design for Access and Mobility (Standards Australia), public and educational facilities must provide accessible drinking water facilities.

We address these requirements with specialised dispenser options designed for universal access. The Billi Quadra with XL Levered Dispenser incorporates extended, ergonomically designed levers that require minimal operating force, making them easy to operate for individuals with limited hand dexterity or mobility. 

When paired with appropriate fonts or risers and installed at wheelchair-accessible mounting heights, these fixtures ensure full compliance with AS1428 design standards, allowing all members of the school community to access fresh drinking water independently.

Hydration for Playgrounds and Sports Grounds

Hydration stations in school grounds, sports ovals, and university quadrangles face intense physical wear and heavy usage. Standard dispensers are unsuitable for these high-traffic zones, which demand heavy-duty fixtures capable of delivering high-volumes of filtered water.

The Billi RM33 Bubbler is made to meet the demands of educational environments. Constructed from heavy-duty, UV-stabilised rotomoulded polyethylene, the outer casing is impact-resistant and rustproof, making it ideal for Australian schools. Featuring a high-capacity chilling mechanism capable of delivering up to 30 litres of chilled water per hour, the RM33 ensures that large groups of students remain hydrated during sports and lunchtimes. Its smooth, rounded design eliminates sharp edges, while splash-resistant drainage bowls maintain hygiene in high-use settings.

Energy Savings During Nights, Weekends, and School Holidays

Educational facilities also face unique energy management challenges due to fluctuating occupancy schedules. Standard commercial appliances that run continuously during overnight periods, weekends, and extended school holidays waste substantial amounts of electricity, driving up operating costs.

To minimise energy waste, our underbench systems incorporate self-learning Eco Intelligence technology. This software monitors daily usage patterns across the campus week and automatically adjusts heating and cooling cycles. During predictable periods of non-use, such as overnight or over the weekend, the system enters a low-power standby mode or shuts down. When student or staff activity resumes, the unit automatically restores water to the desired temperature. 

Furthermore, high-capacity commercial units like the Billi Quadra and Billi OmniOne Pro feature patented heat exchange technology, capturing waste heat generated during the chilling process to preheat incoming water for the boiling tank. This thermodynamic recovery process dramatically reduces overall power consumption, helping educational institutions meet ambitious sustainability and carbon reduction targets.

Hassle-Free Maintenance for Busy Facility Teams

Maintaining water quality and operational reliability across dozens of campus hydration points can place a heavy burden on facility management teams. Filter cartridges must be replaced semi-regularly to prevent sediment accumulation, maintain flow rates, and reduce chlorine, taste, and odour.

To simplify campus asset management, we offer structured BilliCare service plans. Through these service agreements, education facilities receive automated, scheduled servicing from a national network of accredited, security-checked technicians. Regular maintenance includes filter cartridge replacements, system flushes, and performance checks, ensuring uninterrupted operation without consuming internal maintenance resources.

To explore how advanced tapware can transform your campus facilities, you can consult with a Billi commercial specialist and request a commercial quote for your campus. 

Architects, engineers, and specifiers can also download BIM files and technical drawings to integrate Billi systems directly into upcoming refurbishment or new-build plans.

With the Green Building Council of Australia (GBCA) launching its new Green Star Fitouts framework, the priority for architects, interior designers, and commercial specifiers has shifted toward creating lower-carbon, sustainable building design and healthier workplace interiors.

To help architecture and design (A&D) teams navigate these rigorous benchmarks effortlessly, Billi’s flagship under-bench drinking water system, the Quadra, has achieved an elevated Responsible Product Value (RPV) score of 19, backed by Global GreenTag LCARate™ Gold certification and third-party verified Environmental Product Declarations (EPDs).

From AI-curated compliance packages and embedded BIM/CAD file libraries to early schematic design support, discover how Billi eliminates specification friction so you can focus on sustainable interior architecture and high-performance commercial spaces.Integrated filtered water systems are now a common feature in kitchens and workplace amenities.

Their specification is typically guided by visual integration, spatial efficiency and perceived sustainability outcomes. Convenience also shapes selection, as users increasingly prefer immediate access to filtered tap water over relying on packaged plastic bottles. While these drivers are valid at the design stage, they tend to offer limited insight into how systems will perform under sustained use.

Empower sustainable specification with Billi’s Quadra and Quadra Plus.
Featuring high RPV scores and robust Green Star Fitouts compatibility, these systems simplify achieving credits across key categories – helping specifiers meet targets and advance Australia’s transition to a greener built environment.

 

The pursuit of a sustainable built environment is a journey driven by uncompromising vision, unwavering commitment and bold action. Yet, the milestones along the way are not marked by lofty ideals alone – they’re punctuated by the tangible reality of numbers, documents and meticulously measured metrics. This is especially true when navigating the complexities of sustainability certifications and ratings – but the sheer volume of data associated with specified materials and products can feel particularly overwhelming.
And so, with the new Green Star Fitouts rating tool’s launch as a backdrop, we explore how specifiers can strategically consider product selection to achieve tangible results within the established frameworks used today and – through the lens of Billi’s Quadra and Quadra Plus systems – answer a fundamental question: why are product sustainability metrics essential in facilitating this process?

ACHIEVING CREDITS THROUGH SUSTAINABLE SPECIFICATION

Industry professionals will be familiar with the Green Star Buildings rating tool, a fundamental device on the path to Green Star certification. And now, sharing the same methodology, the Green Star Fitouts rating tool is set to roll out, evolving its Green Star Interiors counterpart and raising the bar on carbon, well-being and circularity.
The tool is set to provide a framework to achieve a rating by accumulating credits across five different categories: Circular, Responsible, Healthy, Positive and People. It will set out specific criteria to assess whether – and how well – a project is meeting the credit outcome, falling into one of the performance levels: Minimum Expectation, Credit Achievement and Exceptional Performance.

THE VALUE OF THE RESPONSIBLE PRODUCT VALUE (RPV)

Architects, designers and specifiers will need to demonstrate that the products they specify meet outlined sustainability benchmarks, and a crucial mechanism that will help them assess a product’s contribution to the credits will be the Responsible Product Value (RPV).
An RPV is calculated based on an initiative’s ability to meet criteria that sit across the Responsible, Positive, Healthy and Circular categories. Each of these carries a fixed-point value, and their sum amounts to the product’s total RPV.

HIGHER RPV, HIGHER POTENTIAL: THE QUADRA EXAMPLE

Specifying products with an RPV may contribute towards achieving the Responsible products credits, and Billi’s Quadra and Quadra Plus systems – with an RPV of 19 – are an excellent showcase of that methodology. Their RPV score is based on their Global GreenTag product-specific EPDs – worth 7 points – and their Global GreenTag LCARate Gold certification – which is worth 12 points.

THE GREEN STAR RESPONSIBLE PRODUCTS FRAMEWORK

While the Fitouts tool is yet to be rolled out, the mechanism for assessing products against these categories is already well-established in the Green Star Buildings tool, providing a framework outlining how a product’s metrics can translate into tangible outcomes and ratings.
Quadra and Quadra Plus can contribute to achieving the Responsible Products credits in Green Star. In the Green Star Buildings rating tool, the RPV of 19 allows them to contribute to achieving credits in the Responsible Systems category, placing them in the Exceptional Performance tier with a required minimum RPV of 11 at a product level.

THE ALL-ELECTRIC BENEFITS

As all-electric units, the Quadra and Quadra Plus systems can also help pursue goals related to fully electric and fossil-fuel-free outcomes, which might require the project to use electricity to power heating and cooling, domestic hot water and cooking.

HEALTHY, LOW-TOXIN MATERIALS

Both systems contain no VOCs or BPA and are Watermark and WELL-certified. In addition, the Gold Level certification under Global GreenTag standards, along with the maximum score for Health & Toxicity the products achieve, further highlights the system’s potential to help support obtaining relevant outcomes within existing frameworks.

WATER EFFICIENCY
In addition, Quadra and Quadra Plus systems’ WELs ratings and flow rates – ranging from 5 stars and 5 litres per minute to 6 stars and 4.5 litres per minute, depending on the chosen dispenser option – can help industry professionals meet relevant criteria for water efficiency.

SUPPORTING OCCUPANT WELLNESS
Beyond direct credit contributions, the Quadra and Quadra Plus support the goals of a healthy indoor environment. Their ergonomic design enhances usability, while the silent, water-cooled operation contributes positively to acoustic comfort. And by not requiring cabinet ventilation, they also prevent unwanted heat from impacting thermal comfort in occupied spaces.

EPD AND THE UPFRONT CARBON REDUCTION

Plus, Quadra and Quadra Plus’ product-specific EPDs equip architects, designers and specifiers with a crucial metric they require to meet the upfront carbon reduction criteria – the Upfront Reduced Carbon unit, which is 167kgC02e/Unit for Modules A1-A3 (cradle to gate).
To achieve the credit under Minimum Expectations, the upfront carbon emissions will have to be at least 10% less than those of a reference fitout, for Credit Achievement – 20%, and for Exceptional Performance, the fitout’s upfront carbon emissions will have to be at least 40% less than those of a reference fitout.
Any project seeking a rating under the Green Star Buildings framework will have to reduce its upfront carbon by a minimum of 10% for Minimum Expectation, while any project seeking higher ratings will require a reduction of 30% to achieve the Credit Achievement. Billi’s product-specific EPD provides the exact third-party verified data required to make this calculation.
“It’s essential for industry professionals to collaborate with suppliers to identify opportunities to reduce the project’s carbon footprint throughout the entire supply chain,” says Fergus Tough, Billi’s Director of Manufacturing Operations.

THE COLLECTIVE NEED FOR A SUSTAINABILITY STEP-UP

There is no doubt that architects, designers and specifiers can leverage the potential of sustainable products with robust sustainability metrics – like Quadra and Quadra Plus – to unlock an effective pathway to relevant ratings and a greener built environment overall. And with the new Green Star Fitouts rating tool being rolled out, the navigational toolbox industry professionals have at their disposal is getting increasingly more nuanced and demanding.
“Based on the Green Star Building system rollout in 2022, and the Green Star Fitouts in 2025, with planned stricter requirements in the coming years, we see that the supplier side of the equation will be called to accountability as well,” says Fergus. “This system calls for prior consideration of the end-user’s well-being and better monitoring from cradle to grave of our product lifecycle. This changes the perspective to a much more holistic one and will drive faster improvement in fitout design for the industry.”
Based on the fact that the Quadra system’s cradle-to-grave number is 175.98 kg CO2 Eq (Carbon Dioxide Equivalent) – about 35% lower than the industry average for worst case product (271.7 kg CO2 Eq) – Billi is certainly well equipped to lead the way.

STRENGTHENING “AHEAD OF THE MARKET” COMPLIANCE

Sitting in the top 35% of Global GreenTag internal rankings with “ahead of the market” compliance, both Quadra and Quadra Plus set an example for highly considered product development. But how is Billi planning to strengthen its leadership position in metric-driven sustainable hydration solutions and in Green Star Fitout compliance?
“We have recently launched with BIMSTORE to keep our digital drawing and 3D files accessible and up to date, and we provide ongoing information to third-party industry websites like Architecture & Design to improve product navigation and search,” says Christy Minutoli, Billi’s Marketing Manager ANZ. “We’re also about to release Billi’s first sustainability report and are ramping up our ongoing collaboration with Global GreenTag and the broader architecture and design industry, with a few exciting initiatives currently underway.”
Billi is also transitioning older units to R290 gas. “That means we’ll be adding a few more options to our sustainable products range – and expanding options for Green Star applicants in buildings or specification design.”
Ultimately, the journey towards achieving Green Star certifications and fostering a more sustainable built environment is intrinsically linked to robust sustainability metrics. And as Green Star tools continue to evolve and demand more from manufacturers, products like Quadra and Quadra Plus – with their independently verified metrics, impressive RPV and the company’s plans to expand their sustainable product range – serve as prime examples of how manufacturers can empower architects, designers, and specifiers to make sustainable product choices and confidently navigate the path to achieving their Green Star aspirations.

Launched in 2006, Billi’s Quadra system revolutionised underbench drinking water systems with energy reclaim technology and user-first design. Nearly two decades on, Quadra continues to set the benchmark for efficiency, sustainability and design innovation in residential and commercial water systems.in residential and commercial water systems.

 

 

When Billi launched in 1989, the small, Aussie-grown company was bursting into an establishing water filtration market with some pretty groundbreaking ideas on how to galvanise the industry. And they accomplished this ambitious vision by introducing Australia to the first underbench boiling and chilled drinking water system only a few years later. This pioneering launch laid the groundwork for Billi’s future prominence in the market, setting in motion years of innovation and exciting technological and product releases.

One of them was the landmark launch of Billi’s signature Quadra underbench water system in 2006. Pioneering a unique heat energy reclaim system that significantly enhances energy efficiency, at the time of launch, the Quadra range solidified Billi’s reputation as an innovative, environmentally-driven disruptor in the water systems space. And now, almost 20 years on, we take a closer look at the Quadra range to uncover the innovation behind this revolutionary system, understand how it’s maintained its unwavering relevance over the years, and explore the design philosophy that brought it to life in the first place.

THE END USER
“The end user has always been at the heart of our design philosophy,” says David Craggs, Billi’s Head of Research & Development.
“From the meticulous design of our hot water safety labels and the addition of a digital user interface to expanding user controls for temperature settings, perfecting the spout splash dynamics and dispenser design – we’re constantly improving our product design to enhance user experience.”

It’s evident that the very same, user-driven ethos informed Quadra’s mid-2000s launch. While there was quite a lot of innovation happening in the water system space at the time, Quadra introduced some particularly inventive features that directly addressed shifting consumer needs and evolving requirements of the built environment.
In essence, Quadra’s innovative heat energy reclaim system captures and reuses the energy produced during the chilling cycle to preheat the boiling water, leading to significant energy savings and improved efficiency. In addition, Quadra introduced water-cooled technology, which is generally considered more energy-efficient and does not require cupboard ventilation or a cooling fan, making installation easier, preventing the release of exhaust heat into surrounding cabinetry and ensuring much quieter operation.

This noise-reduced, efficient and space-saving underbench design made it easier to integrate into various residential and commercial environments, offering architects and designers at the time a unique opportunity to specify water systems in applications that weren’t an option before.
With such an outstanding fusion of performance, convenience, improved efficiency and energy savings, no wonder that the ripples of Quadra’s momentous launch still influence the water systems landscape to this day.

QUADRA’S ENDURING RELEVANCE

Since the launch, the range has expanded its product family, and now comprises Quadra, Quadra Plus and Quadra Twin Plus. The Quadra provides instant boiling and chilled filtered water, while the Quadra Plus adds a separate sink mixer tap with its own hot and cold-water supply. The Quadra Twin Plus provides boiling and chilled water and features two separate sink mixer taps with hot and cold water.
Designed to work in commercial and residential spaces, the systems boast a selection of refined dispenser options, including XT Touch, XR Remote, XL Levered and the award-winning Multifunction Mixer Tap, launched in 2024 and recognised with a Good Design Award, complemented by a range of versatile contemporary finishes from classic matte white to urban brass and gunmetal grey. In addition, the XL Levered option is available with red and blue coloured levers and braille pads to support vision-impaired users.

This design versatility is also reflected in the varying capacity of each system, showcasing Billi’s commitment to meeting customer needs and ensuring the best possible experience. Specifiers can select an appropriate system depending on the number of users it’s meant to cater to, hourly delivery of boiling or chilled water cups, and a total current draw needed to accommodate the desired operation. Even the temperature of the chilled water can be adjusted between 6°C and 15°C to accommodate individual user preferences. Billi also offers custom service plan options to ensure continuous safe drinking water onsite – with periodic plans available for locations with multiple units, the company provides a bespoke management system for every customer’s needs.

Alongside versatile choice, outstanding quality and excellent functionality – backed by a two-year warranty – Quadra’s environmental profile continues to be the cornerstone of its unwavering relevance. And essential to its sustainability performance is the natural gas refrigerant (R290) – with a negligible global warming potential (GWP), it plays a critical role in the system’s efficiency.
“R290 exhibits exceptional thermodynamic characteristics, enhancing heat transfer efficiency and expediting cooling processes,” explains Fergus Tough, Billi’s Director of Manufacturing Operations. “As a result, R290-powered systems generally demand less energy for temperature control, reducing both energy usage and utility expenses.”
From a health, safety and well-being perspective, the products contain no VOCs or BPAs and Quadra filters are manufactured with bacteria- and biofilm-resistant materials for improved water safety and quality. Plus, both the “red for no, green for go” smart locking technology with visual safety and fault indicators and the clever Splash Free™ technology underscore the systems’ user-centric character.

A WATER-TIGHT SHIP: RELIABILITY, CERTIFIED

It’s very clear that this holistic design continues to be as relevant as when Quadra first launched, and an array of essential sustainability certifications underscores this enduring character.
Billi is a cornerstone member of the International WELL Building Institute (IWBI), and both Quadra and Quadra Plus are Watermark-certified, have Environmental Product Declarations (EPDs) and are certified Gold Level under Global GreenTag standards. This certification not only reflects their commitment to sustainability across the full lifecycle of the product – including energy and water efficiency, reduced environmental impact, low-VOC emissions, healthy indoor environments, ethical manufacturing practices, and responsible sourcing of materials – but also recognises the maximum score the products achieve for Health & Toxicity, further highlighting their potential to support relevant outcomes within existing frameworks.
For architects and designers striving for sustainable building certifications like Green Star, specifying products with recognised ecolabels provides valuable documentation and contributes towards achieving their project goals. For instance, specifying Quadra and Quadra Plus can contribute to achieving the Responsible Products credits in Green Star. In the Green Star Buildings rating tool, the RPV of 16 allows them to contribute to achieving credits in the Responsible Systems category, placing them in the Exceptional Performance tier with a required minimum RPV of 11 at the product level.

This potential to help architects and designers achieve their sustainability aspirations is underscored by Global GreenTag’s assessment of Quadra ranges’ compliance as “ahead of the market,” positioning them in the top 35% of Global GreenTag’s internal ranking.

STAYING AHEAD OF THE MARKET, LOCALLY AND GLOBALLY

With the “ahead of the market” Global GreenTag compliance under Quadra and Quadra Plus’ belt, Billi, which has just started its global expansion, is looking at a much more complex market of international regulations to adhere to.

“It adds another layer of complexity when we look at sustainability as a manufacturer,” says Royce Tan, the company’s Brand Marketing Coordinator. “It highlights the ‘duty of care’ and our own global impact as an international conglomerate.” With such a strong commitment to industry-wide collaboration, a data-driven approach to innovation and a constant push to advance sustainability ambitions locally and abroad, what’s next for Billi and for the Quadra systems?
“The latest units are based on the consistent success of an all-in-one underbench water filtration solution, like our flagship model, the Quadra,” David says, explaining that the last iteration of the Quadra range, Quadra Sparkling, has now evolved into the OmniOne. “We’ve improved the touchscreen interface in OmniOne, introducing better customisation controls and even safety mitigations in the unit,” he continues. “Now, the new XT Motion will combine the convenience of buttons with motion-sensor controls for all functions on the sides, back and top to enable more convenient, inclusive and hands-free operation, supporting disability access and helping ensure infection control.”

As Billi’s intuitive refinements continue to improve the user experience over the coming years, another challenge lies ahead, and the company is facing it with readiness, curiosity and optimism. “We are approaching the energy efficiency limit of unit design,” explains David. “That’s because it’s impossible to increase the capacity without increasing energy use
or altering the size of the system. So, for us, this will be the most exciting challenge, once we’ve exhausted the limits of conventional appliance design
Based on the Quadra system’s trajectory to date, it’s safe to assume that Billi is most certainly going to rise to the challenge, and we can expect continued market-defying innovations.

We have been working diligently to stay ahead of these regulations. Our Supply Chain Manager Karol Recki recently shared an update on the tangible changes we’ve implemented:

“We changed our polystyrene (EPS) spacers to honeycomb—a biodegradable material made from recycled paper—late last year. While we may still have a small quantity of units at Billi HQ produced prior to the break point, every step we take is designed to eliminate waste. Furthermore, Billi does not use EPE nor EPP for packaging.”

 

Innovation Beyond the Box Our commitment doesn’t stop at the spacers. We are constantly investing in new ways to reduce our footprint. Our team has already commenced investigating the option to move towards plant fibre pallet strapping, ensuring that even the smallest components of our delivery process align with our “Green” philosophy.

 

What This Means for You When you choose a Billi system, you are investing in a brand that values the planet as much as you do.

 

 

We invite you to join us in celebrating this step forward. By choosing Billi, you aren’t just choosing world-class design—you’re choosing a cleaner, greener Australia.

When you are renovating a kitchen, upgrading an apartment, or planning an office fit-out, every inclusion must justify its footprint. Cabinetry is measured to the millimetre, power points are mapped, and joinery is finalised often before appliances are specified.

That is why many designers, homeowners and facilities managers are turning to a compact underbench water systems that deliver filtered boiling and chilled water, and in selected models sparkling and ambient, from a single integrated tap.

Choosing the right system involves more than selecting a finish. Installation considerations, capacity requirements, energy performance and long-term servicing all influence whether a solution is suitable for your space. As an Australian manufacturer with more than 30 years of experience designing and producing underbench boiling and chilled systems in Melbourne, Billi approaches hydration as built-in infrastructure rather than an afterthought. Learn how to assess your options properly and specify with confidence.

 

Why Underbench Systems Are Replacing Traditional Taps

An integrated boiling and chilled tap consolidates the functions of kettles, bottled water, carbonation appliances, and more, into one streamlined solution. The unit sits beneath the bench, freeing surface area while delivering filtered water on demand.

Billi systems are engineered with a compact underbench footprint and incorporate technologies such as heat exchange and energy reclaim, where waste heat from the chilling process assists boiling. Eco and Sahara systems also feature Eco-Intelligence, a self-learning timer that adapts to usage patterns to reduce unnecessary energy consumption.

For renovation projects focused on clarity and performance, and for offices requiring reliable hydration without clutter, underbench systems provide structural efficiency rather than cosmetic change.

 

Confirm Space and Installation Requirements Early

Before comparing models, confirm feasibility. A well-specified retrofit filtered water tap should integrate with existing cabinetry rather than require it to be rebuilt.

However, many of our water-cooled systems do not require cupboard ventilation cut-outs or grilles, which simplifies installation and preserves joinery aesthetics. This is particularly relevant in apartment renovations and commercial retrofits where alterations can be disruptive and costly.

Typical installation considerations include:

 

Planning for these requirements from the outset avoids late-stage compromises. If you are uncertain about suitability for your space, contact our team to confirm installation requirements before finalising specification.

 

Align Capacity With Real-World Usage

Once installation is viable, performance becomes the defining factor. Capacity must reflect genuine demand.

In a residential setting, usage peaks tend to occur during mornings and evenings. Systems within the Billi Home range are designed for domestic environments, incorporating energy-saving modes and select models include boiling safety features suited to family use.

Commercial environments require a more deliberate calculation. A 50-person office can generate concentrated demand during breaks and meetings. The OmniOne, for example, is capable of delivering up to 180 cups of boiling water and 220 cups of chilled or sparkling water per hour, based on one cup drawn every ten seconds, and is suggested for up to 60 people.

Undersizing can lead to recovery delays and strain. Oversizing may increase costs without measurable benefit. Matching the system to the scale of your site ensures consistent delivery and long-term reliability.

For larger workplaces, review our commercial range to compare models against staffing levels and expected usage patterns.

 

 

Integrate Design and Function Seamlessly

Once performance criteria are met, attention turns to interface and aesthetics. A compact system should complement the architectural language of the space.

Billi offers a selection of dispenser styles including XL, XT and XR options, allowing flexibility in form and activation style. For projects seeking a single-fixture solution, the Multifunction Mixer Tap integrates filtered boiling, sparkling and chilled water alongside mains-fed hot and cold water within one streamlined tap body. The ergonomic touch interface is positioned to reduce the risk of accidental activation, and the tap complies with Australian standards including Watermark certification and a 5-Star WELS rating.

Consider Energy Performance and Sustainability Credentials

Sustainable specification now forms part of both residential and commercial decision-making.

Our water-cooled systems utilise heat exchange technology to improve energy performance, and Quadra units have been certified and re-certified by Global GreenTag at Gold Level. An Environmental Product Declaration under EN 15804 further supports transparency in life cycle analysis. We also participate in the International WELL Building Institute’s Works with WELL program, aligning with broader health and wellbeing considerations in building design.

For sparkling systems, the Refillable CO? Plan (within BilliCare) offers a lower-waste alternative to disposable cylinders, with scheduled refilling provided to site.

 

Plan for Servicing From the Outset

A compact filtered water system should be viewed as a long-term asset. Therefore maintenance is important, and should be structured and predictable.

Filters must be replaced at least every 12 months, and commercial sites may require more frequent changes depending on usage and water conditions. Even where usage is light, filters can accumulate organic matter over time, which is why scheduled replacement is recommended.

BilliCare Service Plans provide ongoing support. The Gold Plan includes comprehensive maintenance with filter replacements performed by accredited technicians. The Silver Plan focuses on scheduled filter changes at a fixed rate. For sparkling systems, the Refillable CO? Plan ensures cylinders are replaced and refilled on a planned schedule.

This structured approach reduces downtime, ensures genuine parts are used and provides access to an Australia-wide network of trained service technicians.

 

Choosing With Confidence

Selecting a compact underbench water system is about determining how your kitchen or workplace will function every day.

By evaluating space constraints, confirming installation feasibility, aligning capacity with genuine demand, considering energy performance and planning for servicing, you move from preference to informed specification. The result is a system that integrates neatly beneath the bench, delivers filtered boiling and chilled water reliably and supports long-term performance through structured maintenance.

The right system supports the rhythm of daily use, consistently and quietly. View our full range to compare models or contact our experts to discuss your project.
