A method of moving an underground pipeline including the steps of: driving a casing into a soil proximate to the pipeline; deploying a pivoting wand from the casing about a pivoting axis, the pivoting wand having a plurality of cutting nozzles that are coupled to a fluid conduit having a longitudinal extent in the casing relative to a longitudinal axis; pressurizing the fluid conduit to thereby send fluid through the cutting nozzle to soften the soil in a direction in which the wand deploys; rotating the pivoting wand; conducting the softened soil up through the casing to form a cavity in the soil proximate the pipeline, the cavity in the soil having a shape reflective of the movement of the pivoting wand in the rotating step; positioning a lifting device beneath the pipeline. And, lifting the pipeline with the lifting device thereby drawing the pipeline toward or into the cavity.
