The Great Underground Water Project

The Metropolitan Area Outer Underground Discharge Channel (首都圏外郭放水路) is the largest underground facility in the world to divert overflowing water from nearby rivers to prevent major flooding around the Kanto region. It is located at Kasukabe, Saitama prefecture, which is close to the border of Tokyo.

The most impressive part of this facility, is the surge tank to divert the floodwater, nicknamed “The Underground Temple”.
