Ever wondered how a pipeline goes under a river? In recent years, the development of new technologies mean pipelines can be safely installed, well below the river bed, leaving the environment above intact and undisturbed.
How do we do this?
One of the technologies we use is called horizontal directional drilling or HDD. It allows us to drill beneath the river bed and install the pipeline without disrupting the river flow, surrounding environment, the fish habitat or the riverbank.
This technology also allows us to bury the pipe deeper on both sides of the river bank, offering protection from floods or high river levels.
Several layers of safety
Our teams have been planning the proposed Energy East Pipeline route by taking into consideration a number of factors:
- Avoiding protected areas and known areas of cultural importance to Indigenous groups
- Field studies findings including fisheries, vegetation, traditional land use
- Width and depth of water bodies at the proposed crossing location
- Bed and river bank composition analyses
