▪ First used in Europe in 1870. Patented in US in 1888
▪ Technology introduced to the U.S. by the Electrolux Company
▪ First US indoor/industrial system was installed in the late 1960’s. First US Municipal system was installed in the early 1970’s
▪ Several vacuum manufacturers have been involved in the indoor US systems since the 60’s but now only 2 are active (Airvac and Acorn). Same story in the Municipal market where only 2 are presently active (Airvac and Flovac)
▪ Several other vacuum manufacturers are active globally, primarily in Asia and Europe

General HistoryHistory of Vacuum Technology
Page 6
Vacuum technology uses a pressure differential between
atmospheric pressure and negative pressure (vacuum) as
the propelling force to move liquid in a sealed piping
system
The vacuum is created by vacuum pumps.
Vacuum technology is used a many markets. The 2
primary ones are
▪ Indoor vacuum systems used in a variety of
applications
▪ Outdoor/buried systems used in the municipal market
This presentation will cover both indoor systems as well
as municipal systems

A major jet engine manufacturer operates a catastrophic test burn facility in
Montreal Canada for determining integrity duration of jet engines, should
they catch on fire during flight operations. Once test burning is complete,
the jet engines are extinguished with combination of fire retardants and
water.
Situation
An international construction firm was selected for construction of
wastewater collection area to protect sensitive environmental areas, that
will segregate the liquids contaminated with jet fuel, water and fire
retardants, which could exceed 26K gallons over 5-10 minutes. The site is
located a short distance from a large river and area aquifer.

The vacuum system replaces the existing gravity system. The vacuum wastewater system will be able to safely segregate contaminated fluids and send them for specialized pre-treatment, protecting area aquifers in a closed system.

Vacuum Station SummaryComponents of a Vacuum Station
As valves open and admit atmospheric air, vacuum levels will drop to 16” Hg.
This is sensed at the vacuum station & the vacuum pumps come on to restore
vacuum to 20” Hg.
3) A normally closed interface valve in the valve pit keeps vacuum on the main
4) Interface valve opens, contents sucked out, followed by atmospheric air and differential pressure propels sewage toward vacuum station
1) Vacuum
pumps create a
vacuum on the
collection tank &
then shut off
2) Vacuum mains connected to the tank
extend the vacuum to each valve pit

Completely sealed system
(no spillage = no permit violations)
Self scouring
(unlike gravity where period cleaning is req’d)
Infiltration & Inflow eliminated
A leak in a gravity sewer can go undetected/uncorrected and
allowed to continue to pollute for a long period of time
A leak in a vacuum system is automatically detected and MUST
be corrected for the system to continue to function economically
Protects Ecosystem
Page 43
ADVANTAGE WHY?
Treatment plant not
affected
Vacuum systems are sealed, so massive amounts of I&I cannot enter
the system and overwhelm the treatment plant.
Uninterrupted service All vacuum stations have either a fixed or portable standby generator,
which ensures uninterrupted service to customers.
Less hurricane
preparation required
Vacuum systems eliminate the threat of massive I&I and sewage spills.
In coastal areas one vacuum station typically replaces 7-8 lift stations –
less storm prep work for staff.
Safer working conditions
for maintenance staff
Fixed generators at the vacuum station automatically start during a
power outage. A vital safety feature – no need to expose your
maintenance staff to severe weather.
As a last resort, a vacuum
system can be shut-off
If water levels rise to the point where the air intakes are in danger of
flooding, the entire vacuum system can easily be turned off preventing
damage to the system.
Advantages in hurricane prone areas

Case StudySMART Sewer Solution-Northeast Blizzard is no Match for Smart Sewer
“Relationships with personnel from AIRVAC are of the upmost importance. Clint Hawn (VP Operations) of AIRVAC and I talk monthly. He calls regularly and to check in on how the system is operating, and to ask if there was anything I needed, which is unheard of in this day and age. This is a reason why AIRVAC is successful. Clint and I forme a tight bond during the winter of 2015 where we encountered over 9 feet of snow in addition to an intense onshore northeast coastal ocean flow (flooding) in a four week period. Clint provided additional resources and personnel necessary to assist and fine tune our system. “

Review: WHY VACUUM SEWERS
What are the three main components of a vacuum sewer system?
Valve pits, vacuum mains and vacuum station
How can vacuum sewer systems save money?
Vacuum sewers save money where excavation costs of gravity sewers is high (50+ homes,
flat terrain or rolling hills, high water table, rock or unstable ground, etc.)
What are some environmental benefits of using vacuum sewer systems?
Elimination of I/I is possible
No leaks to the environment even if a sewer pipe breaks
Routing flexibility saves trees & shrubs
Minimal operator contact with sewage
Potential lower energy consumption
