Linking beauty and functionality, Sherbourne Common is the first park in Canada to incorporate a neighbourhood-wide storm-water management system into its design. The water treatment facility is unassumingly housed in the basement of the park’s pavilion and cleans collected storm and lake water with ultraviolet light. (In the future, as the neighbourhood is built-out, it will treat storm-water.) Treated water travels underground to the north side of the park where it is released through three nine-metre-high art sculptures called Light Showers designed by artist Jill Anholt. The water then follows an urban channel out to Lake Ontario.
