Traditional device for damping water flow energy includes a toe basin enlarging in its plane, with 2 vertical walls, and a crest located between the water supply duct with vertical walls and the water discharge duct. In the new design, the toe basin is rectangular-shaped and is equipped with inlet vertical side walls and longitudinal walls which are the continuation of the water supply duct walls. The crest in the plane is designed as a symmetric (about the basin longitudinal axis) curve, formed by 2 bends, with the convex facing the discharge duct. A ceiling is installed over the curved line of the crest upper part.
