In a time of rapidly escalating climate change and increasing urbanization, cities are becoming a microcosm of climate change effects that require a response through the built environment to mitigate these issues. In Winnipeg, this will mean more intense storm events year-round and a variation between droughts and floods yearly, among other problems such as prolonged heat waves in the summer months. With more precipitation predicted for Winnipeg and the continued use of the combined sewer system causing sewage overflows into Winnipeg’s rivers, there is a need to look to green infrastructure to assist or replace Winnipeg’s grey infrastructure for water management. Green infrastructure in the form of constructed wetlands can be strategically incorporated along many of Winnipeg’s creeks to help manage higher volumes of water and purify it before it is released into the rivers. Constructed wetlands can help clean the Red, Assiniboine, and Seine Rivers, positively affecting the endangered Lake Winnipeg downstream, and double as park spaces to add to Winnipeg’s park system. This practicum investigates sites around Winnipeg that provide the potential for implementing constructed wetlands. It also contains a site design concept to show the possibilities of constructed wetlands and how they could be used in Winnipeg to improve the city’s water management system through green infrastructure.
