Fukuzato Underground Dam : ウィキペディア英語版 | Fukuzato Underground Dam
Fukuzato Dam is an underground dam constructed in Miyakojima, Okinawa Prefecture. An underground dam is a wall constructed to save underground water from pouring into the sea so that it can be put to human use. ==Generals== Fukuzato Dam adjoins Sunakawa Underground Dam and experimental underground Minafuku Dam. An underground wall, 27 meters in height and 1790 meters in width stops incoming seawater and outgoing water within the island. The saved water is pumped up through 85 wells for use such as irrigation into the sugarcane fields. One of the good points of underground dams is that the areas above the dams are used as fields, sugarcane fields in Miyakojima and there is no sight of dam lakes.
