A drainage system includes a plurality of water collection pans which may be quickly inserted in the interior cavities of masonry block units over the length of a selected block wall course for collecting the water drained through the interior cavities of the upper courses and directing water to the exterior of the wall. In one embodiment, the collection pans (utilized for units such as bond beam, lintel, or knock-out blocks) includes a collector portion for positioning in the interior cavity of the block and extending across substantially the entire length of the block, the front and rear edges of the collector portion each including a flange extending generally horizontally to contact the top surface of the block, and a drainage channel extending outward from the collector portion past the endwall of the block into the head joint between the block and an adjacent block. Another embodiment of the collection pan designed for use with conventional C.M.U.'s includes a collector portion for positioning in the interior vertical cavity of the block, each of the front and rear edges including a flange extending generally horizontally from the edge to contact the top surface of the block, and a drainage channel extending downward from an opening in the collector portion through the interior vertical cavity toward the front wall of the block and extending below the block so that the end of the drainage channel may be positioned in the bed joint below the block.

[ What is claimed is:] [1.] A water collection pan for use in a masonry block wall having at least one upper block course and a lower block course including a plurality of blocks wherein adjacent blocks are separated by a head joint, wherein the lower block course includes at least one block having at least one interior cavity, and wherein the interior cavity opens to at least the upper portion of at least one of the endwalls of the block, the collection pan comprising:a collector portion for positioning in the interior cavity of the block and for extending across substantially the entire length of the interior cavity, the collector portion including front and rear edges;each of the front and rear edges including a flange extending generally horizontally from the edge for contacting the top surface of the block adjacent the interior cavity, and wherein at least one of the flanges includes a vertical ridge extending from one end thereof to aid in providing a barrier which directs water towards the collector portion of the pan; anda drainage channel extending outwardly at one side of the pan from the collector portion so as to extend past the endwall of the block into the head joint between the block and an adjacent block for draining water to the exterior of the block wall.
