In 2006, the City of Lethbridge partnered with the Oldman Watershed Council to develop ten interpretive signs along the path around the constructed wetland in Lethbridge's first sustainable community of Sun Ridge in southwest Lethbridge. The signs point out features of the wetland and explain the many important functions the wetland performs for the community. In 2010 the same signs will be adapted for the wetlands at the Birds of Prey Centre in Coaldale.
The function of these constructed wetlands is to collect and filter storm water from yards and roads before the water is piped directly into the Oldman River. By doing this wetlands protect the Oldman River from pollutants such as dirt, herbicides, fertilizers, oil, gas and pet waste. They also offer recreational opportunities and beautify our urban spaces.
