Tokyo gets lots of typhoons each year , due to which it’s 12 million inhabitants are continually endangered by flooding. So it’s quite a big problem for the Japanese government. But most surprisingly they have come across with a brilliant idea to address this problem. So look what they have done, they have constructed the most massive pumping system which began in 1992, with the completion scheduled for 2009.This $2 billion system includes a four mile long network of tunnels connected to an 83-foot-tall storage tank and a cathedral -like structure of 59 massive pillars.
The system’s powerful turbines has the ability to pump 200 tons of water into the Edogawa River each second. The system has become a Tokyo tourist attraction, and can be visited for free.The main water tank resembles a temple and has been used in some movies and TV programs to create mystic scenes.
