Stormwater Siphon Cube

1) A stormwater syphon cube which comprises:

• an elongated cube shaped device installed in a river bed or water channel through which stormwater flows into the entrance of said cube device with a rock screening grate and with a series of internal valves that act to channel water either straight through said cube and back to the stream or to divert water out through a side port extraction pipe which carries said water diagonally at a shallow angle and out of the water channel or river bed via gravity;
• a plurality of valves and plates within said cube in which an exit valve located at the back end of said cube comprised of a plate with an axel attached to the interior of said cube is acted upon by a retractable cable which can either close the plate valve against the top edge of said cube by a cable pull or release said plate to drop via gravity and water pressure and lay flat against the bottom of said cube thus allowing water to pass through said cube unhindered;
• and a second valve comprised of a series of plates on hinges where one hinge is attached on the side and at the upper portion of said cube so that when acted on by a cable retraction said plates will lift and fold up against the top inside surface of said cube and thus allow water within said cube to leave via a side extraction pipe and when said cable is released said plates will unfold and drop via gravity to form a flat barrier hanging against the side wall of said cube and thus act to close off water flow out of the side port extraction pipe;
• and where said side hanging plates have a leading edge bevel that acts to keep the valve closed as water presses against said bevel in the closed position and keeps valve plates from moving into the center stream of water moving through said cube.
