The solution.
As part of a groundbreaking 10-year pilot, the Rotteveels combined a Hydraloop H300 unit with MijnWaterFabriek's SafeWater technology to create a fully circular water system. Rainwater is collected via a coarse filter into a 10 m³ tank and purified for use in showers, baths, sinks, and the garden. Hydraloop treats greywater from the showers and baths, making it safe for a second use in the toilets and washing machine. Only the kitchen relies on mains water.
The result.
This smart, two-stage system cuts drinking water use by over 90% and reduces wastewater output by 40%, while continuously monitoring water quality and performance. Every drop is reused intelligently, transforming the home into a living example of circular water innovation.
"To live as sustainably as possible, save drinking water, capture stormwater, and inspire others to integrate sustainable water solutions in their home or project. We want to be a motor for the water transition we are facing!" — Mark & Elvira Rotteveel
