## Description
NGN has an obligation to frequently survey its LTS pipelines, and a limited number of specific distribution mains, to identify building encroachments, ground movement, activities or potential activities by third parties in close proximity to a pipeline or specific main. A key requirement of the survey is to ensure that third parties do not damage, interfere or cause an escape of pressurised gas from NGN's assets.Aerial surveillance is an established and effective method of surveying long lengths of buried pipelines to identify threats and is deemed as an essential safety related service by the Company.
