Abstract
A portable toilet comprises a spout via which accumulated waste contents are dumped at a suitable sanitary disposal station.

For dumping the two sections are separated. The spout is rotatably mounted in an aperture in the top wall of the holding tank and is swung from its stored position and a cap at the end of the spout is unscrewed. A vent valve is also provided in the top wall of the holding tank and it is manually operated by the person dumping the holding tank so as to vent the head space during dumping.
