A sewer cleaning module for cleaning sewer pipes in preparation for relining. The module is assembled in situ and the relative size of components is selected depending upon the diameter of the pipeline. The module may comprise a front unit and rear unit or a frame assembly and a drive assembly. The modules contain a motor, preferably a hydraulic motor. The motor drives flails, thereby disintegrating solid waste or generating and propelling a sludge slurry. The slurry scours the pipeline walls by cavitation and abrasion action. Also disclosed are systems for cleaning a sewage line section and methods of their use.
