What are steam tunnels for?

Answer 1

Utility tunnels (Steam Tunnels)

Universities and other large institutions, such as hospitals, often distribute steam for heating buildings from a central heating plant. These steam ducts are generally run through utility tunnels, which are often accessible solely for the purposes of maintenance. Many of these steam tunnels, such as those on college campuses, often also have a tradition of exploration by students.

Steam tunnels in general have been getting more secure in recent years, due to their use for carrying network backbones and perceived risk of their use in terrorist activities, safety and liability.

Some steam tunnels have dirt floors, no lighting and can have temperatures upwards of 115 degrees Fahrenheit (46° C). Others have concrete floors, bright light, and can even be quite nice and feature a cool temperature. Most steam tunnels have large intake fans to bring in fresh air, and push all of the hot air out the back.

Answer 2

They are used to get steam, water, gas, and electrical power from one point to another underground. Every building with a steam boiler must have someone in attendance 24 hrs a day, 7 days a week. For multi-building campuses, it is therefore more economical to have a central "power plant" to service the other buildings.
