The present invention discloses a sewage slurry separation system adapted to assist in sewer cleaning operations. The sewage slurry separation system is configured for collecting sewage slurry from a sewer line, depositing the sewage slurry in a collection/settling chamber to separate the slurry into water and sludge. The water is then pumped back into the sewer line. The system includes a sewage collection tank with a compacting plate. The compacting plate divides the sewage collection tank into a sewage collection chamber and a water collection chamber. The compacting plate has a passage that allows water from the sewage collection chamber to flow into the water collection chamber. The sewage slurry separation system also includes a submersible pump connected to the sewage collection chamber. The submersible pump pumps sewage slurry into the sewage collection chamber.
