In this paper we make research on an equitable cost allocation of cooperative sewerage system for regional environmental management. We formulate it to apply a characteristic function form game, i.e., a local government is to be assumed a player in the sewerage system game. This game theoritical research is used two kinds of conceptual solution for equity to resolute conflicts among players. Two solutions are Shapley's “Value” and Schmeidler's “Nucleolus”. The empirical study has been done at Lake Kasumigaura where the eutrophycation has been progressing. In comparison with the practical institution, to conclude an equitable cost allocation of regional public goods such as sewerage system we must take spatial location of each local government into account.
