ABSTRACT
Ecological design includes specifications that foster the desired vegetation, and optimize the value of the system to wildlife and humans. Physical design encompasses all the choices of how the wetland basin is built, and how the water is conveyed to and through the system. From a water quality standpoint, the goal of interior design is to maximize the efficiency of the system footprint. General conditions of the potential site will have been considered during the establishment of the basis of design. In general, there will remain a number of possibilities for the location of the system within the overall site confines. The designer has wide latitude in the selection of plant species and mixtures thereof. Vegetative diversity is only partially controllable in design and operation of a treatment marsh. Wetland treatment system construction can be broken into two topics: site civil construction and vegetation establishment.
