摘要

The device has a three-dimensional mesh (4) for filtering rain water, and water collectors (2) serving as a buffer zone for collecting and channeling the rain water towards a water tank (1) through gutters. The three-dimensional mesh is filled with a base material (3) for permitting vegetation of plants on a surface of a roof.
