Abstract: A technique for aiding an underground communications cable installer in the installation such cable in underground utilities neighborhoods. The technique manages the problem presented by a surface-visible, underground-pathway obstruction such as a sidewalk, which lies across the path of installation. The technique, or method, is useful with any kind of cable, such as fiberoptic cable or copper wire cable. Hydraulic water pressure is applied through a biased, flexible conduit to erode a pathway under the obstruction from ground surface on one side to ground surface on the opposite side of the obstruction, thereby forming a tunnel under the obstruction through which the cable can be easily pulled. In alternative embodiments, the cable can be inserted directly into and through the conduit while it is underground, the conduit then acting as a sleeve for the cable which is subsequently removed prior to burying the cable in a trench dug from street-located handhole to house. Special apparatus connects a water hose to the flexible conduit (PVC plastic) to provide watertight operation while allowing manual flow control.
