Retention sedimentation basin is for drainage system and has at least one overflow device connected to retention sedimentation basin in water course and entirely under water surface
The retention sedimentation basin is for a drainage system and has at least one overflow device (1) connected to a retention sedimentation basin in a water source (3) and entirely under the water surface. The sedimentation basin (5) on the upper side is connected to the water course. One of the inlets (14) is provided with a deflector on the inside of the basin for deflection of the fluid flow along the bottom of the basin. The basin has at least one inlet connected with the overflow device which issues in the bottom of the basin. A membrane separates a part of the basin connected to an overflow at least partly from the water course. The membrane is balloon-shaped.
