A device for emptying a sewer well that comprises a lower relatively heavy fraction and an upper relatively light fraction, the device comprising a lower suction nozzle with a lower suction opening for removing the lower fraction, said lower suction nozzle being connected to a pump, wherein at a position remote from the lower suction nozzle the device comprises an upper suction nozzle for removing the upper fraction.
A method for emptying a sewer well that comprises a lower relatively heavy fraction and an upper relatively light fraction, comprising sucking at least a part of the lower fraction by means of a pump through a lower suction nozzle with a lower suction opening near a bottom of the sewer well, wherein the method further comprises the step of sucking at least a part of the upper fraction by means of the pump through an upper suction nozzle located at a position remote from the lower suction nozzle.
