The AcornVac
® system uses differential air pressure to
transport waste from plumbing fixtures, such as toilets,
urinals, sinks, and showers, through a piping network to a
central point from which waste is discharged into the
facility's sewer or waste treatment plant. The vacuum center
is the heart of the system. It controls the vacuum pumps to
create vacuum pressure in the waste piping, allows incoming
air to assist in drainage from the toilet when it is
flushed, and empties accumulator tanks that collect
wastewater from other sources. For more on how vacuum
plumbing works, visit the
