<p>An apparatus and method for removing sediment from a waterway using a high pressure water spray and a suction line is disclosed. The high pressure water is directed through a pressure line. The high pressure water helps to suspend sediment that has settled in the waterway. Water and suspended sediment is then vacuumed up by the suction line and deposited outside the water for further treatment or disposal. The apparatus is designed to be hand-held by an individual situated in the waterway, such that great control over which specific locations within the waterway are being treated. An outlet from the pressure line is selectively moved between a first position to direct pressurized fluid against the waterway surface to be treated and a second position that enhances removal of the water with suspended sediment.</p> |
