The land filtration treatment process is shown to be competitive with advanced treatment plant alternatives from the standpoint of cost and performance. Supporting material for the studies includes a review of current literature, two intensive studies of the land treatment process, and engineering experience. The approach taken by the Corps assumed that: (1) pollutants are resources (or assets) in the wrong place that should be used; (2) the water carrying these resources should also be used; (3) effluents from treatment systems should contain only background levels of these pollutants; and (4) the benefits generated by achieving high levels of water quality on a regional basis should offset the economic costs. The Chicago study investigated three alternative treatment methods: an advanced biological plant system, a physical-chemical plant system, and a land filtration system. The land treatment system eliminated treatment plants altogether and utilizes aeration lagoons and spray irrigation methods to remove waste constituents from the water.
