WCW24

During a heavy rainfall in early June 2023 a sinkhole developed over a large diameter storm outfall that threatened nearby homes and the Albert Memorial Bridge. In response, the City activated the Emergency Operations Centre which undertook an emergency project to restore critical storm water service to protect public health and safety. The project presented many challenges including tight timelines and working conditions, working on private property and managing public expectations, the application of innovative construction techniques, and coordinating the efforts of numerous City departments, various levels of government, and public sector partners. This presentation details the efforts taken to stabilize and eventually decommission the outfall while at the same time maintaining storm water service.
