<p>The trough has a water flow surface (2) extending inclinedly from a water flow delivering upper zone toward a water flow recovery lower zone, where the upper zone comprises a delivery nozzle (3). A chute (4) comprises a water evacuation core that is connected with a pumping circuit (5) to draw water in the chute and to supply the water to the nozzle when the pumping circuit is active. The nozzle is oriented toward a deflecting wall (7) placed in an upper part next to the flow surface.</p> |
