Recuses would be easier, spectating would provide spectacular views and the neighborhood is stunning:
The project would transform a side canal that has been closed to boat traffic for the last decade. At one end, a natural filter, made of layers of gravel and pollution-eating plants, would purify the river water flowing into the pool. A bypass would send sewer water in another direction, and the top of the structure would turn into a pedestrian and bicycle bridge. The beginning of the canal would be "re-naturalized" into a refuge for urban wildlife and a new park.
