A drainage quilt which operably rests adjacent to a subterranean conduit and facilitates water removal and dispersal from underground drainage sites. The drainage quilt includes a water permeable membrane configured in a generally rectangular container and a plurality of drainage members disposed within the container. The drainage members are composed of recycled or new plastic or chunks of old rubber tires and are positioned in a homogeneous fashion to create drainage channels through the subject quilt. Flexible positioning ties extend perpendicularly through the rectangular container to retain the relative positioning of the drainage members. The ties prevent the drainage members from assembling at any one area of the drainage quilt and thus encourage an equal distribution of fluid flow throughout the quilt.
