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.
