A reduction system using water pressure and vacuum excavation and including a water supply tank, water pump, vacuum pump, slurry collection tank, a system for tilting the collection tank, handheld reduction tool, and a drive system. The reduction tool, or wand, is used to deliver high pressure fluid, such as water, to the ground in order to loosen soil directly in front of the tool. The tool includes diametrically opposed nozzles which are angled with respect to one another such that pressurized water delivered from the nozzles is directed in a fashion to slice the ground in a generally spiral or helical fashion as the tool is pressed downward into the ground. As the soil is loosened by the pressurized water delivered from the nozzles, the loosened soil is sucked away to form a hole in the ground, and such loosened soil (a slurry when mixed with the water) passes upwardly through the tool in a vacuum air-flow created by the vacuum pump and is deposited in the slurry collection tank.

1. A reduction system for moving and collecting material, the reduction system comprising:a collection tank for receipt and accumulation of the material; an elongated reduction toot connected to said collection tank for lifting and removing the material from a location; said elongated reduction tool defining a free end and an elongated transport passage extending therethrough for transporting the material; and said reduction tool having a peripheral wall defining an inlet at said free end; said inlet being in fluid communication with said elongated transport passage; a source of pressurized liquid, said source of pressurized liquid being connected to said reduction tool for delivering a pressurized liquid flow to said reduction tool for direction by said reduction tool against the material for loosening the material; a plurality of nozzles in said transport passage adjacent said inlet for directing the pressurized liquid towards the material, at least one of said nozzles being configured for emitting the pressurized liquid generally parallel to said transport passage towards said inlet, and at least one of said nozzles being angled inwardly and configured for emitting the pressurized liquid towards said transport passage; and a source of vacuum connected to said reduction tool and to said collection tank, said source of vacuum creating and drawing a vacuum flow through said collection tank and said reduction tool for pulling the material through said reduction tool and into said collection tank.
