1. A drainage system, comprising:
a geographical area including a drainage area from which drainage water is to be drained and a flowing water body having flowing water flowing in a flowing water direction;
a drain inlet opening in the ground at the drainage area;
a drain conduit having a longitudinal drain conduit axis disposed at an acute drain conduit angle with respect to the flowing water direction as measured on an upstream side of the drain conduit, the drain conduit comprising:
a tapered drain conduit inlet end having a conduit inlet opening disposed in fluid communication with the drain inlet opening, the conduit inlet opening of the drain conduit inlet end having a lower edge portion, an upper edge portion and an inlet opening plane disposed at an acute inlet plane angle with respect to the longitudinal drain conduit axis of the drain conduit at the lower edge portion;
a conduit bore disposed in fluid communication with the conduit inlet opening; and
a tapered drain conduit discharge end having a conduit discharge opening disposed in fluid communication with the conduit bore, the conduit discharge opening having an upstream edge portion, a downstream edge portion and a discharge opening plane disposed at an acute discharge plane angle with respect to the longitudinal drain conduit axis of the drain conduit at the upstream edge portion and oriented parallel to the flowing water direction of the flowing water in the flowing water body; and
whereby as the flowing water in the flowing water body adjacently traverses the conduit discharge opening, the flowing water induces negative fluid pressure through the conduit discharge opening, the conduit bore and the conduit inlet opening of the drain conduit and in the drain inlet opening, respectively, and the negative fluid pressure draws drainage water from the ground at the drainage area through the drain inlet opening and the conduit inlet opening, the conduit bore and the conduit discharge opening, respectively, of the drain conduit into the flowing water body.
