摘要：<p>The column has a sump pump (11) for aspirating water in a chute (13) and rising waste water level above the ground for passing the waste water to an evacuation network. A sensor (1) is located in a lower part of a water aspiration zone. A control unit (9) triggers the starting of the pump based on the water level measured by the sensor and prevents the entry of water by acting on a solenoid valve (5) when the water level is very high.</p>
