Vanpile’s scope of work was to provide maintenance dredging at Kinder Morgan’s Vancouver Wharves location, moving approximately 1300m3 of contaminated material.

The maintenance dredging was completed along Berths 1, 4, and 5 at Kinder Morgan’s Vancouver Wharves location.
The contaminated dredged material was placed by clamshell onto a small, plastic lined flat scow. As decant water was not permitted back into Burrard Inlet, a key component was to create a completely sealed holding platform:

  •  A concrete block wall lined with filter fabric contained the dredgeate;
  •  A drain pipe installed within the wall allowed for water to pool into a secondary holding area, also contained by a block wall lined in fabric;
  • The water was then pumped into a tank where it was sorted for pump transfer to Kinder Morgan’s existing filtration system.

After initial drainage of approximately 12 hours, dredged material was transerred by clamshell to haul trucks dockside, where it was to be stockpiled separately from that of Berths 4, and 5. Upon acceptable levels of decant, all materials were then hauled to Sumas Remediation’s Burnaby treatment facility.
