On a small strip of land between the Emscher River and the Rhine Herne Canal in Germany sits a rest stop whose colorful appearance belies its radical purpose. The structure’s artful design consists of pipes leading from two toilets and the Emscher (the most polluted river in Germany) that converge at a small community garden and drinking fountain. The garden is, in fact, a manmade wetland that collects, treats, and cleans the effluence from the toilets and river—making it drinkable.
A new pool has just opened in the heart of London's King's Cross. In the centre of one of the city's largest mixed-use development projects Ooze Architects, in collaboration with artist Marjetica Potrc, have developed and realised "the UK's first man-made fresh water public bathing pond" as a piece of and art. The oblong pool is forty metres long, built two metres above ground level, and is surrounded by "pioneer plants, wild flowers grasses, and bushes so that the environment evolves as the seasons change." It will be purified through "a natural closed-loop process, using wetland and submerged water plants to filter and sustain clean and clear water."
