In watershed areas of Meguro River flowing through Tokyo, urbanization has been promoted since the Meiji Period, and the water quality was extremely deteriorated in the high-growth period. Then, bubbles of detergent floated on the water surface and unpleasant odors were produced over a long period. Later, the water quality and scenery were dramatically improved through the introduction of sewage systems and local citizens’ efforts.
However, there are many combined sewer systems in the watershed area of Meguro River even today, and there are some problems such as the river giving off a bad odor at times of flooding. Currently, various approaches aiming at water environment improvement such as releasing reclaimed sewage water and water purification experiments by using highly concentrated oxygen dissolution water are being conducted to restore the watershed areas where people can enjoy cherry-blossom viewing.
