Project location: Orange County is located in the Los Angeles metropolitan area in Southern California. This area, which has ecological diversity and needs to be examined and protected, is being restored and promoted with a new project. While protecting the environment, it is aimed to ensure the sustainability of the site and to investigate and protect the ecological diversity there. While the research of ecological diversity in the area is being carried out, it is also aimed to design a living machine that cleans the city's sewage from the water released into the ocean through this river and brings it back to nature.
