摘要

The apparatus (1) has a temporary water settling and storage container integrated with a reservoir (3) and around which a draining material (9) is distributed. The container has a connecting unit (39) that is arranged on an inlet zone (23) to channel water directly in the container and to temporarily store the water in the container. Diffusion units (29, 33) are arranged to filter water stored in the container and to diffuse the water in the material. The container has inspection units arranged between the reservoir and ground level to permit cleaning.
