Method and apparatus are described for removing material from a sump. The sump has substantially parallel and elongated sidewalls and has a longitudinal axis. The sump is enclosed with ends and a bottom and is adapted for filling with a water-solid mixture to form a slurry. A suction pump is mounted above the sump and extends into the sump for removal of the water and solid material. Apparatus is attached to the suction pump for moving the suction pump along the longitudinal axis of the sump. When the suction pump reaches the end of the sump, apparatus rotates the suction pump through 180 degrees and then the moving apparatus again moves the sump along the longitudinal axis to the other end where it is again rotated in the opposite direction through 180 degrees to the original point for repeating the process. |
