Specifying Water Systems for Multi-Residential Developments
Multi-residential developments are expected to deliver more functionality, convenience and value than ever before.
As kitchens become more compact and resident expectations continue to evolve, architects, developers and specifiers are increasingly challenged to maximise every square metre without compromising design quality, sustainability objectives or the resident experience. Decisions that were once viewed as simple product selections now play a broader role in shaping how apartments function and how developments are perceived.
Water systems have become part of that conversation. Once considered a basic utility, integrated filtered water systems can contribute to kitchen design, appliance consolidation, sustainability goals and premium resident amenities when specified appropriately.
With more than 30 years of experience designing and manufacturing instant filtered water systems, Billi understands the practical considerations that influence specification decisions across residential and commercial projects. From compact underbench footprints and water-cooled technology to sustainability initiatives and WELL-focused design principles, modern water systems offer opportunities that extend beyond drinking water.
Why Water Systems Belong in Residential Specification Discussions
Specification decisions are increasingly being evaluated through a wider lens than cost and compliance alone.
Developers want apartments that appeal to modern buyers and residents. Architects are tasked with balancing aesthetics, functionality and spatial efficiency. Interior designers seek solutions that integrate seamlessly into contemporary kitchens. At the same time, sustainability targets and wellbeing considerations continue to influence project requirements.
Against this backdrop, water systems are not always a plumbing fixture. They have become part of the broader discussion around resident experience, kitchen functionality and building performance. The questions have refocused on how water access can be delivered in a way that supports the goals of the development.
The Space Challenge in Residential Kitchen Design
Few areas of a residential development face greater pressure than the kitchen.
People expect generous storage, quality appliances and practical preparation space, yet kitchen footprints often require designers to achieve these outcomes within increasingly efficient layouts. Every specification decision therefore competes for valuable space. This is where integrated underbench water systems can provide a practical advantage.
Billi systems are designed with compact underbench footprints, helping preserve storage capacity while supporting a more integrated kitchen layout. Our water-cooled systems also do not require cupboard ventilation cut-outs or cooling fans, which can simplify cabinet design and installation planning.
For architects and specifiers, this means:
- More efficient use of underbench cabinetry.
- Reduced benchtop clutter.
- Greater design flexibility.
- Cleaner joinery outcomes.
- Improved integration with contemporary residential kitchens.
This shift towards appliance consolidation aligns with broader residential design trends where functionality, simplicity and efficient use of space are increasingly valued.
How Integrated Water Systems Support Premium Resident Amenities
Premium developments are often distinguished by a collection of thoughtful decisions rather than a single standout feature.
Residents tend to place value on amenities that improve everyday life. Features that are used regularly often contribute more to the perception of quality than features that are impressive on inspection but rarely used afterwards.
Filtered water access, instant boiling water for hot beverages and cooking, chilled water for hydration, and sparkling water for entertaining all support daily routines. These functions are woven into how residents use their kitchens throughout the day.
For developers, this creates an opportunity to view water systems as part of a broader amenity strategy rather than simply a utility. They become one of many decisions that contribute to convenience, functionality and the overall living experience.
However, the suitability of any specification should be assessed against the project’s target market, positioning and objectives.
For developments seeking to deliver a more premium resident experience, integrated water systems deserve consideration alongside other kitchen and lifestyle inclusions.
Sustainability Considerations for Multi-Residential Water Filtration
Sustainability objectives increasingly influence product selection throughout the specification process.
Architects and developers are often required to consider not only how a product performs today, but how it contributes to broader environmental and wellbeing goals throughout the life of the building.
For water systems, this means evaluating more than the availability of filtered water. Energy use, installation requirements, certifications and sustainability credentials all become relevant considerations.
Our water-cooled systems incorporate heat exchange and energy reclaim technology, recovering waste heat generated during the chilling process and using it to assist the production of boiling water.
Furthermore, our sustainability and wellbeing commitments include:
- Global GreenTag certification (for Quadra units only).
- Cornerstone Membership with the International WELL Building Institute.
- ISO-9001-14001-45001 certification.
- Alignment with United Nations Sustainable Development Goals.
These credentials provide specifiers with tangible information that can be assessed alongside project sustainability objectives rather than relying on broad environmental claims.
What Architects and Specifiers Should Assess Before Selection
Selecting a water system should begin with project requirements rather than product features.
The most successful specifications are those that align with the intended resident experience, available space, operational requirements and long-term objectives of the development.
Before selecting a system, architects and specifiers should consider:
- Required Water Functions: Does the project require boiling, chilled, sparkling or still filtered water, or a combination of these functions?
- Available Underbench Space: How much space is available within the kitchen cabinetry, and how will the selected system affect storage capacity?
- Installation Requirements: Are there ventilation requirements, additional services or design constraints that need to be accommodated?
- Design Integration: Will the dispenser design and finish complement the wider kitchen specification?
- Sustainability Objectives: Does the system align with the project’s environmental, wellbeing or certification goals?
- Maintenance Requirements: How will filters be replaced, and what servicing support will be available after handover?
- Resident Profile: What level of functionality and convenience is appropriate for the target resident demographic?
Approaching specification through this framework helps ensure the selected solution supports the wider goals of the project rather than simply meeting a minimum functional requirement.
Long-Term Maintenance and Resident Satisfaction
The specification process should extend beyond installation day.
Water systems require periodic maintenance and filter replacement (at least every 12 months) to maintain water quality and performance. While this is a normal aspect of ownership, it should be considered during project planning rather than after residents move in.
Developers, building managers and body corporates benefit from understanding maintenance requirements early, particularly in larger multi-residential developments where long-term management strategies are important.
Key considerations include:
- Filter replacement schedules.
- Service access requirements.
- Responsibility for ongoing maintenance.
- Availability of genuine replacement filters and parts.
- Access to qualified service support.
For this reason, we offer service plans, genuine replacement filters and support from trained technicians and service agents. Considering these factors during specification can help support a positive resident experience throughout the life of the development.
