Abstract: A modular drain for receiving drainage liquid with a polygonal upper portion and a lower portion. The upper portion has a substantially lateral surface, a first vertical surface and a second vertical surface that define an upper cavity, the substantially lateral surface having a plurality of openings thereon. The lower portion is joined to the upper portion, the lower portion including a substantially semi-circular surface sized to receive a tube section of a connector therein. In one embodiment, at least one of the first vertical surface and the second vertical surface includes a retention mechanism that is sized and positioned to retain the tube section in the lower portion. In another embodiment, the vertical surfaces are provided with interlocking interfaces.

Abstract: A modular trench drainage system for placement in a trench of a natural surface or pavement. The system includes a base conduit, a grate cover pivotably secured to the base conduit for covering the base member, a coupling mechanism for pivotably securing the grate cover to the base conduit, an alignment mechanism for aligning the grate cover with respect to the base conduit when the grate cover is placed in a closed position over the base conduit, and a locking mechanism for locking the grate cover to the base conduit.
