We undertake a preventative maintenance dig when our ongoing monitoring and inspection program alerts us to a pipeline feature that may require a closer look.
Pipeline construction: Safety and the environment
With proper design, construction, operation and maintenance, pipelines have a very long life. The safety of people, and protection of the environment, is our top priority throughout the entire pipeline lifecycle.
Safety goes beyond preventing incidents on our systems. We also devote our energy and resources to keeping our neighbors and communities safe.
After construction of energy infrastructure, Enbridge's goal is to restore the affected area (including pipeline rights-of-way) to as close to pre-construction condition as possible, and minimize our long-term impact to the land.
Hydrostatic testing is a carefully planned and controlled process that confirms a threshold measurement for a pipeline's safe operations.
