Abstract: A ruggedized portable water treatment system having a protective exoskeleton that supports and enshrouds the principle operating components of the water treatment system. In one embodiment, the water treatment system includes a water pump and one or more water treatment components that are disposed within the protective confines of the exoskeleton. In one embodiment, the exoskeleton includes top and bottom plates that are joined by a central support and a plurality of external supports. The principle operating components of the water treatment system, such as the water pump and the water treatment components, are mounted to the central support and are fully contained within and protected by the external supports. The external supports are disposed outwardly of the water pump and the water treatment components to form a rigid cage configured to protect the internally positioned components.
