Prefab drainage system used on new Canada Line

As Vancouver prepares for the 2010 Winter Olympics, work continues on the supporting infrastructure including upgrading and expanding the region’s transit system.

The new Canada Line is an automated light metro system running 19 kilometres from downtown Vancouver to Richmond Centre and the Vancouver International Airport. Approximately half of the new line runs underground.

On one of the underground sections, known as the “Cambie Street Cut and Cover”, limited space meant that relieving hydrostatic pressure would be a challenge using conventional techniques. Nilex Nudrain WD15 was used to provide the necessary drainage in a fraction of the space normally required.

Nilex Nudrain WD15 prefabricated drain combines high-flow drainage capabilities with very good compressive strength and is typically used in vertical applications as was the case on the Canada Line.
