Each flush should be an isolated batch of sewage that is subject to automated analysis to insure that it is not contaminated with chemicals or solid foreign objects that would interfere with the recycling process that will be vital to the colony. Pressing the flush button should cause the cause the toilet lid to fasten securely isolating the batch. Scanners would check for the presence of RFID tags which will be incorporated into towelettes that people will use to clean themselves. The towelettes should be disposed of in a separate recycling system specialized for washing them. The presence of a towelette in the toilet bowl will activate an out-of-order signal for maintenance service to unfasten the toilet lid, fix the problem, and return the toilet to service.

Each flush should be an isolated batch of sewage that is subject to automated analysis to insure that it is not contaminated with chemicals or solid foreign objects that would interfere with the recycling process that will be vital to the colony. Pressing the flush button should cause the cause the toilet lid to fasten securely isolating the batch. Scanners will check for the presence of RFID tags which will be incorporated into towelettes that people will use to clean themselves. The towelettes should be disposed of in a separate recycling system specialized for washing them. The presence of a towelette in the toilet bowl will activate an out-of-order signal for maintenance service to unfasten the toilet lid, fix the problem, and return the toilet to service. In case there are no RFID tags in the bowl, automatic machinery will stir the contents and force it through a screen using added water as necessary. Solid objects that do not go through the screen will also activate an out-of-order signal. Automatic chemical analysis will be the last step before packing the batch into a barrel for shipment to the central sewage treatment facility. Sewer pipelines connecting each toilet with the sewage treatment facility would be convenient but there needs to be allowance for the air tight emergency isolation doors which will close automatically in case there is a breach in the integrity of the pressure vessel that forms the compartment in which the toilet is located. Fresh air and stale air ducts will need to have their separate air tight isolation doors in case of emergency, but isolation doors for hot and cold water pipes and sewage pipes would be an excessive complication. In case of a breach, affected compartments will need to function on canned oxygen generators, canned CO2 scrubbing units, and emergency sanitary procedures which might, depending upon the nature of the emergency, result in some stored sewage to be processed later. </ins></div></td></tr>
