Abstract
A drainage system for delivering fluid from a source of fluid for absorption into the ground, comprises a trench, a pair of perforated drainage conduits extending longitudinally in said trench and laterally spaced from each other to define an open chamber therebetween. The conduits are connected at one end to the source for receiving fluid from the source and delivering fluid to the chamber. A longitudinally extending cover overlies said conduits and prevents soil from falling into the chamber. The cover includes side portions which engage the conduits and a center portion connected to the side portions and maintains the conduits in laterally spaced relationship. The cover also includes reinforcing arches extending between the side portions and the center portion to resist downward deflection of the cover under the weight of the top soil. Vent holes in the cover permit the system to breathe.
