A type approval for an on-board sewage treatment plant type which, based on design and configurations criteria, covers on-board sewage treatment plants of different dimensions (in particular as concerns the maximum daily volumetric flow rate of sewage Qj and the daily pollutant load DBO5) and configurations (in particular as concerns the location of the component parts and their sizes), but not plants using different treatment procedures; appendix 1 “Main characteristics of the on-board sewage treatment plant type” needs to be added to the information document referred to in Annex 7, Section II, both for the plant earmarked for testing in accordance with Annex 7, Section IX and for each of the other plants. The respective serial numbers need to be indicated (referred to in no. 1.2) and the various values for the daily volumetric flow rate of sewage Qj and for the daily pollutant load DBO5 (referred to in no.3) Alternatively, appendix 1 can be presented in tabular form. If necessary, appendices 5, 7 and 9 are also to be appended for each configuration that differs from that of the test installation.
