Shepard Stormwater Diversion Project Implementation
GENERAL CONTRACTOR: Top Notch, Calgary, AB
PROJECT NOTES: The City of Calgary undertook a massive diversion project to provide a route for stormwater to reach the Bow River. As a result of the flow containment, additional development in the drainage area will be possible. The completed project intercepts stormwater from areas of southeast and northeast Calgary and the Elliston Storm Pond, directing it down a 4km channel through a 560 acre constructed wetland, and finally to a 9.5km ditch that flows to the river. The wetland will provide treatment of incoming stormwater, improving the quality of the water that reaches the river.
Construction on the $58 Million Shepard Stormwater Diversion Project began in June 2006 and was completed by the end of 2008. Brock White Geotechnical in Calgary assisted with the construction of the overflow spillways around the perimeter and throughout the project, as well as supplying 7oz non-woven Geotextile, Pyramat and 4" Tri-Lock.
