Tokyo emergency flood system

.
Wow. Just wow.



The system drains water from several small rivers into a huge underground tunnel and pumps it into Edo river at the flood-safe point.

Thus saving Tokyo metropolitan area from flooding when these rivers become overfilled during the rain seasons or in case of typhoons.
