The City of Calgary has long taken a proactive approach to the management of their feedermain network. This includes an advanced condition assessment strategy that combines an inspection program and risk analyses to better develop an understanding of the safety and reliability of the network. The program began in 2004, after a 1200-mm feedermain catastrophically failed and released 20 ML of water, flooding a roadway and disrupting service to over 100,000 customers. Over the years, successful inspections have allowed the City to proactively repair damaged pipes. In 2018, the City completed multiple inline inspections with the SmartBall® leak and air pocket detection tool, identifying major leaks on two critical Feedermains. The inspections pinpointed the leak locations, allowing the City to repair and potentially prevent a catastrophic failure.

This presentation will provide an overview of Calgary’s long-term strategy in regard to the management of their feedermain network, while highlighting recent success stories, including damaged pipes that were identified and repaired prior to a failure.
