Project by Marjetica Potrc and Ooze (Eva Pfannes & Sylvain Hartenberg)
'Between the Waters: The Emscher Community Garden' is a water-supply infrastructure line between the Emscher River and the Rhine-Herne Canal. The project is a complete and sustainable water-supply system. It uses only water from the immediate area: the Emscher River, the Rhine-Herne Canal, rainwater and waste water. By putting the treatment process on display, it shows it is possible to reclaim and restore the natural habitat by using low-tech processes to construct a high-tech system. The main elements of the water supply and treatment installation are two toilets located above the Emscher River (the most polluted river in Germany), a pump that draws water from the river into a septic tank, a constructed wetland, a rainwater-harvesting roof, water storage bags, and a fountain located above the Rhine-Herne Canal that offers visitors water of drinkable quality. In addition, the system provides water for irrigating the Community Garden.
