A sanitation system, particularly for use in vehicles such as marine vessels (boats), trains, planes, etc. Into a holding tank with a sloping bottom containing sewage from a toilet system, such as a vacuum toilet system, about eight ounces of deodorant chemical is automatically injected into the tank approximately every 48 hours. This effectively controls odors while minimizing chemical consumption. A gas vent from the tank passes through a vent filter having a first type of activated charcoal effective against H2S, and a minor amount of activated charcoal effective against amino acid gaseous compounds, the vent filter removing odors. A tank cap in the top of the cap supports "high" and "full" level indicator switches and allows for the injection of the chemical and the gas vent. A tank cleaning device comprising a piece of surgical tubing with a nozzle at its free end and connected to a source of liquid under pressure can also be utilized. In use, the nozzle impacts the tank walls while spraying liquid in it to effect cleaning. A control module and control panel provide for an indication of the tank liquid level, control of the injector pump, and control of the discharge pump which discharges sewage from the holding tank.
