In June 2013, flooding through the Fort McMurray area caused substantial damage to infrastructure and loss of land along the Hangingstone River. With funding from the Province of Alberta emergency relief program, the Regional Municipality of Wood Buffalo retained Urban Systems to evaluate, design, and administer construction to reclaim lost land and replace lost infrastructure. The works involved three different sites and included reconstructing 700 lineal meters of river bank and reclaiming lost land, reconstructing an adjacent road and paved pedestrian trail, reconstructing a 400 mm diameter watermain crossing the river which was completely destroyed by scour during the flood, and replacing a 250 mm sanitary sewer syphon crossing the river that was damaged during the flood. Pipe installations were done with both open trench and directional drilling methods. During the investigative stage of the project it was discovered that the existing sanitary syphon was leaking sewage into the river, therefore urgent actions were required to first isolate and repair the existing pipe until such time that the new syphon was in service. The total value of the works was approximately $7 Million and successfully completed in 2014.
