Abstract
Abstract A portable sanitary facility is disclosed which, in one embodiment is particularly adapted for use by males needing only to relieve themselves of liquid body wastes. A sanitary unit is carried by a trailer to achieve portability between a use station and a disposal site. The sanitary unit includes a main compartment more or less encompassed by a trough with apertures being provided in the compartment walls to drain liquid introduced into the trough into the compartment interior. The main compartment is divided into a plurality of sub-compartments by transverse vertical baffles which include a series of apertures for establishing liquid communication between the subcompartments. The baffles serve to prevent shifting of the liquid load and thus stabilize the trailer during transport to a disposal site. A valved outlet is provided to permit draining the facility at a disposal site. Removable access covers permit entry into the facility interior during fabrication, maintenance and cleaning. In a second female or all-purpose embodiment a plurality of toilet seats and aperture over each subcompartment are provided in the top of the compartment to receive solid and liquid wastes, and modesty apartment means enclose each seat to give privacy. Means for converting solid waste to liquid waste are provided.
