The purpose of this practicum is to design a landscape with the ability to purify wastewater from Winnipeg North End Water Pollution Control Centre and to use the purified water for the irrigation of community gardens. Water pollution has been a big issue around the world. Eutrophication refers to the overabundance of nutrients in waterbodies. Lake Winnipeg, in the province of Manitoba, one of the largest freshwater resources in Canada, has a serious eutrophication problem. One of the major nutrient loading sources is the nutrient-rich inflow from the Red River (Water Stewardship Division, n.d.), which consists of agricultural runoff and municipal and industrial wastewater. In the City of Winnipeg, the North End Water Pollution Control Centre releases a large amount of treated wastewater into the Red River. The treated wastewater is rich of phosphorus, nitrogen, and pathogen. The landscape can play a potential role to purify the nutrient-rich wastewater before it reaches the river while providing outdoor spaces for community gardens and leisurely uses. === October 2016
