A levee and barrier module for fluid control and containment is provided including an outer module shell and a module-to-module connection system to attach adjacent outer shells. The outer module shell, being in the general shape of a prism or prism with curvilinear section, is formed by opposing side walls and two opposing end walls, and is configured to enclose or support filler material. The two opposing end walls are configured with end apertures. The outer module shell defines a top aperture and a bottom aperture. When modules are placed end to end in a levee structure the end apertures allow filler material communication horizontally between adjacent modules. The bottom aperture allows filler material communication with the earth below the module. The top aperture allows filler material to be added to the module, as well as visual observation of, and maintenance of, the amount of contained filler material.
