One park in Toronto is doing more than its share in recycling natural resources. Michael Van Valkenburgh Associates Inc. designed the Corktown Common park, which takes water recycling to the next level. As Emily Mueller De Celis, project manager of Corktown Common park, told Popular Science: "Every drop of water hitting the park is reused at least two or three times before it's absorbed or evaporated away." For example, rainwater that drains from the playground flows through an ultraviolet filter as well as a constructed marsh before feeding into the park's irrigation storage. According to the design firm, the park saves about 550,000 liters of rainwater per day in the peak season. This system also prevents flooding of the surrounding residences during heavy storms.
