A utility tunnel, utility corridor, or utilidor is a passage built underground or above ground to carry utility lines such as electricity, steam, water supply pipes, and sewer pipes.
The most famous of which are located beneath Walt Disney World in Florida where, among other things, the utilidors are used for waste removal. The Magic Kingdom uses an automated vacuum collection (AVAC) system for waste removal. Custodians remove trash from the park twenty-four hours a day, then dump it into AVAC system processors throughout the park. The trash then travels through pneumatic tubes to a central location where it is processed and compressed for transfer to a landfill or recycling plant. (Wikipedia)
