As part of the Trans Mountain Expansion Project, we’re adding 12 new pump stations to the pipeline system, 11 for the new pipeline and one for the existing pipeline. Pump stations are a critical component of the operations of our pipeline system. They contain electric motors to drive the pumps that maintain the pressure and flow rate in the pipeline. 

Ten of the new pump stations will be added at existing facilities, with the final two being added at a new site in BC. The Engineering, Procurement and Construction Contractor responsible for the work on the pump stations is CORD.

There are a number of steps involved in preparing the pump station sites for the arrival of construction crews and equipment, including:

  • Placing a One Call, locating and marking of all buried facilities
  • Surveying
  • Flagging and staking the work-site and any temporary workspace required for construction
  • Installing signage
  • Clearing trees and vegetation from pre-approved areas essential for construction
  • Disposing of unsalvageable timber, like branches, tree limbs or shrubs left behind from clearing.

After site preparation, construction takes place within the footprint of the existing pump station and includes:

  • Installing piles and pouring concrete
  • Installing mechanical equipment
  • Piping and tie-ins (welding) 
  • Construction of structural steel and buildings
  • Electrical installation and instrumentation
  • Insulation and pre-commissioning
  • Clean up and restoration activities  

During construction our crews follow all applicable noise bylaws and the Trans Mountain Noise Management Plan, including the installation of a sound barrier to reduce construction related noise for our neighbours.

Strategies for avoiding or reducing potential environmental impacts will be employed at all stages of construction by following our Environmental Protection Plans. Our goal is to protect the environment, have as little impact as possible and, where we do have an impact, ensure we return the land to a similar function. Throughout construction, work will be monitored by Environmental Inspectors and Indigenous Monitors.
