Social system and production system in the modem society are closely related to the wide field, and it becomes a complicated thing. Various environmental problems exist in the social structure. It is necessary to analyze the effect from various sides for the solution of such problems. Especially, the load to the environment may be made to increase in the integrated network infrastructure, if the consideration from the stage of plan and design to environmental harmony-ness is not sufficiently carried out. In this study, it stood at the viewpoint of life cycle of facilities until the disposal from the design, and environmental effect of disposal, operation and construction in the social foundation facility was determined quantitatively. Considering this background, as one step in solving these environmental problems the Life Cycle Assessment (LCA) technique for environmental impact assessment will be examined in this research. As the result, the LCA technique can be called that the application to social foundation facilities represented for the waste water treatment system is also sufficiently possible and that to also make in addition, the wide-area environmental problem to be an object is possible, and that it is a point the quantitative evaluation, and that it is the very effective environmental impact assessment technique.
