Abstract
Abstract A portable building is formed of plastic and the walls have vertical ribs for rigidity. A plastic waste tank within the building is in juxtaposition with three walls of the building and has grooves which mate with the wall ribs to lock the tank in place. A weir in the tank divides the tank into two compartments. The toilet seat is over the larger of these compartments. A urinal on the building wall has a drain leading into that larger compartment.
