Abstract: An apparatus and a method of extracting buried lead water supply pipe with minimal excavation and which allows removal and containment of the lead pipe. The extraction apparatus includes a frame having an upwardly extending mast, a guide pulley mounted on the frame, and a pulling apparatus. A take-up spool is mounted on the mast between the guide pulley and pulling apparatus and positioned to allow a pipe pulling cable to be wrapped therearound into a non-linear path between the guide pulley and the pulling apparatus. Extracted pipe is pulled into the non-linear path until the pipe is fully extracted from the ground. Multiple spiral loops around the take-up spool by the pulling cable may be necessary to fully contain the extracted pipe. Following extraction, the pipe may be unspooled from the take-up spool, the pulling cable removed for re-use, and the pipe may then be sent for disposal.

Abstract: A method of in-situ pipeline replacement in which valves, fittings, and other obstructions are removed from an existing pipeline, a heat-fusible polymer pipeline having an initially deformed configuration less than the existing pipeline diameter is inserted into the remaining portions of the existing pipeline and reformed to substantially conform to the inside diameter of the existing pipeline, heat-fusible fittings are provided to replace removed portions of the existing pipeline and heat-fused to the polymer liner, and transition fittings provided to operably connect the replacement pipeline to those portions of the existing pipeline not within the replacement scope. The completed replacement polymer pipeline creates an operable wetted pressure boundary within the bounds of the replaced existing pipeline.
