The tank has a lateral surface (1) including an inner side, which is provided with horizontally extending reinforcing ribs (2) i.e. planar plastic strip. The ribs are combined in pairs to form a profile with a V-shaped cross-sectional surface, and are connected each other by a weld seam (3). Free ends of a side of the V-shaped cross-sectional surface lie at an enclosed wall of the tank and connected with the enclosed wall. A surface of the reinforcement ribs is provided with openings, which are provided for passage of tank contents. |
