This study aims to verify the effects of water quality trading to preserve sustainable water quality in closed water bodies such as Tokyo Bay. To verify mainly economic efficiency of water quality trading, the authors have created the water quality trading model to preserve sustainable water quality in Tokyo Bay by advanced wastewater treatment, where all costs of sewerage works have been grasped and pollution ratio with wastewater from households is relatively high. As a result of comparison of total costs to reduce amount of pollutant (nitrogen, phosphate, etc.) and preserve water quality in Tokyo Bay between pre- trading and post-trading with the model, it has been appeared that totally about 10 % cost reduction is possible by introduction of water quality trading, and water quality trading can be an effective policy to strive to make the total cost as small as possible and to meet environmental quality standards for water pollution with the minimum total burden in a basin.
