Claim 4:
5. A system for removing groundwater from an interior space of a building structure; the system comprising:
a foundation wall that extends beneath the surface of the ground, the foundation wall comprising an interior surface; an exterior surface and a lower surface;
a footing upon which the lower surface of the foundation wall is disposed, the footing comprising an interior horizontal surface and an interior vertical surface;
a plurality of interconnected panels, the interconnected panels comprising;
(i) a first horizontal panel disposed atop at least a portion of the interior horizontal surface of the footing, the first horizontal panel comprising an upper surface and a lower surface;
(ii) a second panel with an inner surface and an outer surface, the second panel connected to the first panel at a first flex segment, the second panel substantially vertically disposed with intermittent perforations therein and disposed in at least one of (a) contact with the interior vertical surface of the footing, or (b) proximate the interior vertical surface of the footing;
(iii) a third panel with an inner and an outer surface and intermittent perforations therein, the third panel connected to the second panel at a second flex segment and extending diagonally upward;
(iv) a fourth panel with an upper and a lower surface, the fourth panel connected to the third panel at third flex segment, at least a portion of the lower surface of the fourth panel laid atop the upper surface of the first horizontal panel; and
(v) a fifth panel with an inner surface, an outer surface and a top edge, the fifth panel vertically oriented with the outer surface in contact with the foundation wall;
wherein groundwater flows through the intermittent perforations into a channel formed by the second and third panels, the groundwater moving to a point of ejection from the system.
