The invention relates to an arrangement in a vacuum sewer system, which comprises a sewer network having a sewage source and sewer piping adapted for receiving sewage from the sewage source. A liquid driven ejector device functions as a source of vacuum for the vacuum sewer system. In order to improve the efficiency of and to ensure the function of the ejector device, the ejector device forms a primary circuit, which is separated from a secondary circuit formed by the sewage collecting process.
