Abstract: A rain collecting wall system comprising a plurality of interlocking wall components each with a chamber for storing water; sets of teeth disposed on either side of the wall components, the sets of teeth allow the wall components to be arranged to form a structure wherein the first set of teeth of a first wall component engages the second set of teeth of a second wall component; an aperture disposed in each set of teeth adapted to receive an anchor for supporting the wall component in an upright position; structural supports for helping the wall components resist bowing; at least one water access point disposed; and a mounting system for attaching building materials or shelving systems to the wall components.
