Saving City

It is a water cycle installation in the city with a focus on conservation and innovation, including the treatment and reuse of rainwater, graywater and wastewater on a city scale. When the installation is not in use, the circles will stop on the empty path at the bottom, and visitors will use the clues on the graphic to move the circles to their right places. The circles need to be anchored in the spots where they are supposed to sit and can be moved on the hollow when desired.
