Pipeline surveys take place throughout the year with the majority of the surveys taking place from spring through fall each year. Our trained technicians and contractors inspect the full length of our pipelines on a rotating schedule checking more than 21,000 kilometers of pipeline across Alberta to ensure their integrity. Pipelines cross both public and private land, so technicians may occasionally need access to your property or may be seen crossing your property. Surveys require no digging, cause no disturbance, and will not affect your natural gas service.
