Garbage Collection Engineering!

When the first Disneyland was opened much credit was given to the engineering that went into handling and collecting waste. Extensive use of underground tunnels were used to keep the park above clean and waste free.
It appears that waste will now be on the move underground using giant vacuum conveying. Who knows we may even have a GIGO (Garbage In Garbage Out) B Tech degree course!
