eco-cistem™ in partnership with Thomas Dudley.
Introducing the world’s most environmentally friendly toilet cistern – eco-cistem™, a breakthrough in sustainable water management. Developed in partnership with Thomas Dudley, this concealed cistern is the first of its kind to harness condensate from air-conditioning units, transforming what was once wasted into a free, renewable source of water for flushing toilets.
By reusing air-con condensation, eco-cistem™ reduces reliance on mains water, lowers utility costs, and supports smarter building design. It’s a simple yet powerful innovation that combines sustainable engineering with smart functionality—ideal for commercial spaces, hospitality venues, and eco-forward developments.
Until now, this free source of water has gone to waste. With eco-cistem™, it’s finally put to work-quietly, efficiently, and sustainably.
