▪ 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

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

Background

Commercial SystemsInternational Construction Firm, Montreal, Canada

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.

▪ Solution

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.

How it Works

Industrial Market 2/8/2016

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

PacVac

• Airvac has several PacVac

models that will fit to projects

until 550 connections.

Cost Savings + Environmental Impacts


˃ Septic tank replacement projects

˃ Private development projects

˃ Failing gravity system replacement (CSO)

Who Is A Candidate?

˃ Flat terrain

˃ High groundwater table

˃ Unstable and unsuitable soil

˃ Rolling hills

˃ Rocky terrain

˃ Sensitive eco-system

Where Does It Apply?

Shallow, narrow trenches =

Less excavation

Dewatering minimized

Smaller equipment

Smaller diameter pipes

1 vacuum station can

replace 6 or 7 lift stations

(some that are deep)

Deep gravity lines = deep lift stations (can be 30+ ft deep)

Cost Savings

Reduced Impacts From Construction

˃ Less surface disruption

˃ Less restoration

˃ Less property disruption

˃ Vertical & horizontal

routing flexibility

1 vacuum station typically

replaces 6 or 7 gravity lift

stations eliminating the need

to pump & re-pump

Energy Conservation

Completely sealed system = no operator contact with raw sewage

No confined space issues (no exposure to H2S)

Operator Friendly

Standby generator =

uninterrupted service to the

customer

Fewer lift stations = Fewer instances of “not in my

backyard”

Customer Acceptance

Vacuum stations are typically designed to take

on the character of the neighborhood

The vacuum station on the left is in the same neighborhood as the house on the right

Aesthetics

Bio bed for vacuum exhaust

Air Terminal

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

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. “

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


What are some other benefits of installing vacuum sewer systems?

–Minimal impact on local traffic and businesses

–Best system in areas prone to flooding

–Excellent solution for seasonal flow variation

–Immediate leak detection and quick location avoids environmental problems

–No line blockages

–Ease of line repair

–All mains are PVC or PE which can flex in shifting ground

–Only 1 source of power (no electrical homeowner service upgrade)

–Safety during construction

–Odor and corrosion minimized

–Minimal exposure of employees to sewage
