Challenging storm drainage project

Flat grades, a constrained alignment, deep excavations and viscous native silt material made this a particularly interesting project to design and construct.

This facility would also provide underground storm sewer servicing to existing commercial properties and accommodate future residential development.

After the town was successful in their application for a Building Canada grant, Opus DaytonKnight proceeded with design of the first phase of the South Trunk Storm Sewer project.

Construction of the approximately 640 metres of 1500mm diameter storm sewer was completed over the following two construction seasons. With the exception of approximately 50 metres of steel installed by pipe ramming across a major highway, sheet piled open cut excavation was undertaken to install the new gasketed reinforced concrete storm main.
