Joosten and EWB collaborate on sustainable rainwater purification and storage

Collaboration between Joosten and EWB
Challenges with flooding, drought, and drinking water shortages dominate our daily news. With solutions such as infiltration systems and water buffering—sometimes combined with sewer disconnection—Joosten Groep is already at the forefront. But what if we could also purify the captured rainwater?
We are taking the next step together with startup Ecologisch Water Beheer (EWB). EWB’s Rain Shell system enables the storage and purification of runoff rainwater from organic pollutants, heavy metals, mineral oils, and PAHs. This is achieved using natural, circular, and renewable materials: shells and minerals. By not only storing but also purifying rainwater, it becomes suitable for reuse in a variety of household and industrial applications. Additionally, safe infiltration is possible in nature reserves, groundwater protection areas, and for deep infiltration.
The collaboration gives EWB Circular Rain the opportunity for scaling up, further development, and optimization of its systems.
