Shallowly Buried. Gas lines can be as shallow as 12 inches below the surface. Plastic lines need to be at least 18 inches in some areas and require a metal wire to be wrapped around them. This allows a pipe finder to locate the pipe if necessary. The gas lines run to a meter that is normally located on the side of the house.
This depth allows for the required minimum of 30 to 36 inches of cover. Additional cover for the pipeline is provided at road and waterbody crossings, while less cover (a minimum of 18 inches) is required in rock. The trenching crew uses a wheel trencher or backhoe to dig the pipe trench (Figure 2.1-2).
