As an integral part of an ecosystem, water is often present in the various parts of the system’s circulation, connecting various organisms. For a city, the water supply and purification system are hidden in the pipes that connect various buildings. When we think of New York City as a vast ecosystem, the water cycle is a vein hidden behind the grand architectural facade. This design doesn’t water to be internalized but a visible and spatial component of the City. The design introduces ecological thinking to the hidden water purification system of NYC, poetically expressing ecology, and in that process, the project creates a wild urban space. In the design of the ecosystem, I have focused on the circulation and evolution of water, its connection to the urban water supply system with the site, and translate the water tower-water pipe system ecologically, so that it can be perceived and paid attention to by the city in a more intuitive way both above and below the ground. This is visually and spatially expressed by the combination of the following elements: water towers used for storage, expressive piping for distribution, and various landscape features including artificial plants to disperse water or topography to collect the water. By reconfiguring the systems of water purification the project creates a thriving ecosystem that is an educational experience and pleasant place to visit. It not only moves water but also people and provides various levels of vegetated spaces for people to inhabit and by combining natural and synthetic elements a new urban wildness is created.
