Reuse the main structure and the forgotten space beneath the abandoned Water Towers of Ho Chi Minh City, Vietnam in the 1969s. These water towers, in large numbers, are scattered throughout the city, with enormous demolition costs and the risk of pollution and significant energy consumption when dismantling them. “THE FUNNEL COLOUR” creates a solution for reusing these abandoned water towers, forming a series of recirculating water filtration systems along the Saigon River—the main river of the city—while also creating a new community space that connects people with each other and with nature, establishing a symbiotic and sustainable relationship.
