 Vacuum sewers were first used in Europe in
1882. However, it has been only in the last 30 years that vacuum
transport has been utilized in the United States. During this
time, the use and acceptance of vacuum sewers have expanded greatly.
In the 1970’s, vacuum sewers
were still regarded as new and only to be used as a system
of last resort. Improvements in the technology later led
to acceptance as an alternative to gravity sewers, but still
only to be used when significant savings would result. Now,
vacuum sewers have become a system of choice as they are
providing efficient and reliable sewer service to communities
all around the world. Currently more than 700 AIRVAC vacuum
systems are in operation in the United States and in foreign
countries. |
