University of Wisconsin Stevens Point is said to have had a secret underground
tunnel system. Some of the tunnels still remain, and some exist as steam supply
and condensate return systems, which heat the campus buildings.
Rasmussen, UWSP Director of Facilities Planning, knows a little bit about this
system is not a “tunnel” in the sense that it can be accessed by anyone to
travel from building to building,” Rasmussen said.
the tunnels are used as steam supply and condensate return systems. The
majority of the piping is located within a concrete box conduit. The space
inside is only about 20 inches high by 28 inches across. In some areas of
campus, there is no box conduit, and the steam lines are directly buried in the
network includes about 2.5 miles of piping in order to supply all the buildings
that are connected to the George Stien central heating plant, located on Maria
Drive, with heat,” Rasmussen said.
the way are a series of “steam pits.” The utility pits are buried belowground
and can be accessed by campus maintenance personnel, but they do not lead
anywhere. The pits serve only as junction points for servicing individual
buildings or as break points for long runs in the supply lines.
similar two-mile long pit and conduit system exists for the buried electrical
system supplying electrical service to the campus buildings.
electrical conduits that run from pit to pit are even smaller than the concrete
box conduit carrying the steam lines. Usually two to eight pipes, about four
to eight inches in diameter, are buried three feet belowground and encased in
concrete to protect them from damage,” Rasmussen said.
pits can also be accessed by campus maintenance personnel, but they do not lead
anywhere. As with steam, the pits serve only as loop points for serving
individual buildings, or as inspection and pull points for long runs in the
electrical supply lines.
is one true tunnel that connects the Park Student Services Center with the
Dreyfus University Center. This tunnel is open to the public and can be used
during the hours that the buildings are open,” Rasmussen said.
tunnel once existed between Old Main and the Student Services Center, but it
was removed in 1979 when former wing additions on the east and west sides of
Old Main were torn down.
small remnant, only a few feet long, was retained as a small storage closet
for the Student Services Center,” Rasmussen said.
interior service tunnels also exist within the Science, Health Enhancement, and
Noel Fine Arts buildings. They are there mainly to route utility pipes and move
air within the buildings that do not include basements in their construction.
coal storage bunker also still remains under the parking lot near Old Main,
from the days when coal was burned at a small central heating plant before it
was relocated north to Maria Drive.
bunker now serves mainly for routing electrical, communications and steam
supply lines and occasional temporary storage,” Rasmussen said.
