The excavation system is comprised of a jetting system and a dredge pump combined into a manipulator-held nozzle assembly (Figure 20.15). The system provides sufficient power to break large solids and excavate any solid up to 3 inches (76 mm) in diameter. Dredging and jetting opera- tions can be used alternately or simultaneously.
