Subterranean Lines

Definition - What does Subterranean Lines mean?

Subterranean lines are defined as any public service utility infrastructure installed beneath the earth’s surface. Subterranean lines include, but are not limited to telecommunication, electrical, water, wastewater, cable, or internet lines. Subterranean lines are maintained by the relevant public utility companies responsible for their installation.

Subterranean lines are also known as underground utilities, underground lines, or subsurface utilities.

Trenchlesspedia explains Subterranean Lines

Subterranean lines are typically installed underground for aesthetic, convenience, or functional purposes. Accurate location of these lines is essential prior to subsequent construction activities since they are hidden from view. Inadvertent contact with subterranean lines can result in several hazardous situations as well as lengthy and expensive downtime of the specific utility.

As such, minimal impact techniques, such as hydro excavation, are used in areas where existing subterranean lines may be present. Slot trenching via hydro excavations are also commonly used to install new subterranean lines due to their increased efficiency, faster installation times, and naturally safe operation.
