An automatic tank clean out system provided in the slurry collection tank a soil reduction system. When the slurry collection tank becomes full, the vacuum system is automatically shut down to prevent the slurry mixture from being drawn into the vacuum pump. When it becomes necessary to empty the slurry collection tank, the liquid contents can be drained through a valve in the tank. A series of nozzles, such as fan nozzles, are provided which are connected to a water supply pipe running axially through the tank. These fan nozzles are actuated to deliver high pressure water to automatically clean the tank.
