Abstract: A water collection and drainage system is described for a masonry block wall having bond beam block courses and intervening standard block courses. A system of upper water collection pans is supported along each upper bond beam course. Downspouts leading from drain openings in the upper collection pans drain collected water from the pans through the vertical block cavities in lower block courses to the next lower series of collection pans. The lowermost bond beam course supports a series of base collection pans which collect water drained through the vertical block cavities from the upper collection pans. Weeping spouts lead laterally from the base collection pans to the exterior of the wall to continuously drain collected water from the interior wall cavities.
