In a major step forward for sustainable building innovation, Thomas Dudley has announced a landmark partnership with eco‑cistem™, introducing the world’s first toilet cistern engineered to reuse condensate from air‑conditioning units. This breakthrough technology captures a free, previously wasted water source and repurposes it to flush toilets - dramatically reducing freshwater consumption across commercial and residential environments.
Turning Waste Into a Renewable Resource
Air‑conditioning units naturally produce condensate as they operate. Even a compact 1.75 kW unit can generate over one litre of water per hour - water that traditionally drains away unused. eco‑cistem™ captures this resource and stores it within an 18‑litre cistern, providing a reliable, sustainable supply for toilet flushing.
When condensate levels are low, the system automatically switches to a backup mains water supply, ensuring consistent performance even in high‑usage settings. If the toilet remains unused for extended periods, surplus condensate is safely drained away, maintaining hygiene and system efficiency.
A New Benchmark in Environmental Performance
The eco‑cistem™ system is being hailed as the world’s most environmentally friendly toilet cistern, combining sustainable design with smart, practical functionality. Key environmental benefits include:
- Significant reduction in freshwater demand
- Lower carbon footprint through reduced water processing and supply
- Zero electricity requirement
- Compatibility with grey water inputs for enhanced eco‑efficiency
The system is also the first and only cistern to earn both BREEAM credits and LEED points, making it a powerful asset for architects, developers, and sustainability‑focused organisations.
Designed for Seamless Integration
Engineered with versatility at its core, eco‑cistem™ integrates effortlessly into modern washroom environments. Its compact dimensions—485mm (W) x 476mm (H) x 195mm (D)—allow it to fit within fitted furniture, tiled walls, and a wide range of partitioning systems.
It supports:
- Wall‑mounted, frame‑mounted, and fully concealed installations
- Both wall‑hung and floor‑mounted WCs
- Pneumatic activation with manual or infrared flush plate options
- Adjustable flush volumes between 6L and 3.5/2L
Each unit is supplied with mounting brackets, flush pipes, and air tubes, ensuring straightforward installation. A wide selection of finishing accessories—including push plates, buttons, levers, and touch‑free sensors—allows full customisation to suit any aesthetic or specification.
Ideal for High‑Demand, High‑Impact Spaces
eco‑cistem™ is designed for environments where sustainability and performance must work hand‑in‑hand. Ideal applications include:
- Hotels and hospitality
- Offices and commercial buildings
- Residential developments
- Retail spaces
- Leisure centres
- Any building equipped with air‑conditioning
A Partnership Built on Innovation
The collaboration between eco‑cistem™ and Thomas Dudley brings together two leaders in engineering and water‑saving technology. With decades of manufacturing expertise and a shared commitment to environmental responsibility, the partnership aims to redefine how buildings use and conserve water.
“This partnership represents a major leap forward in sustainable washroom design,” said the Thomas Dudley team. “eco‑cistem™ aligns perfectly with our mission to deliver high‑performance, environmentally responsible solutions for the built environment.”
A Future Where Every Drop Counts
As global water scarcity intensifies, innovations like eco‑cistem™ demonstrate how everyday systems can be reimagined to conserve resources without compromising performance. By capturing water that would otherwise be lost, this partnership sets a new standard for sustainable building technology - one that is practical, scalable, and ready for widespread adoption.
