The invention relates to a street grid (1) for surface drainage. Said grid consists of a frame (10) and a grating (11), which are adapted to the contours of a paved gully in order to be integrated into the latter, for draining water that flows towards the street grid in a pre-defined direction. The aim of the invention is to ensure permanent drainage. To achieve this, recessed inlet openings (13) are provided in the upper edge of at least one lateral wall of the frame that guides the water in the flow direction. |
