Six-year Silverthorn storm trunk sewer build at halfway point

A severe storm which hit Toronto almost 20 years ago causing major property damage is the driver of a massive infrastructure project. Designed by CH2M Hill Canada Ltd (now Jacobs), the $400-million Fairbank Silverthorn Storm Trunk Sewer project is an undertaking which took years of planning and design, required shipping a tunnel boring machine from France, and is only about the half-way point of approximately six years of construction.
