ABSTRACT:
A ground drainage system includes a relatively narrow, elongated trench disposed along a roadway (or agricultural field); and a drainage tube construction disposed in the trench. The tube construction including a plurality of longitudinally extending, substantially tangential and generally parallel corrugated tubes oriented with respect to one another in a linear fashion. In transverse cross-section the portions attaching the tubes to another define a generally straight line perpendicular to the longitudinal dimension of the tubes. The tubes are generally vertically stacked with respect to one another. The corrugations are defined by alternating ribs and valleys. Each tube has perforations in the valleys to allow fluid to enter therein and be drained away.
