underground pipelines
Subterranean utility channels
Underground pipelines are pipes buried beneath the surface to transport liquids or gases over distances—oil, natural gas, water, or sewage.
The term emphasizes their hidden infrastructure: The explosion was traced to aging underground pipelines.
Pipeline networks crisscross continents, often becoming visible only when they fail or when new construction sparks controversy.
