WaterCon - AIRVAC Vacuum Sewerage Systems

Why AirVac Vacuum Sewerage systems?

 

The Company

 

AIRVAC Vacuum Sewerage Systems offer a cost-effective, environmentally sound alternative to traditional gravity sewerage systems.

 

AIRVAC are the world leader in vacuum sewerage system technology for over years. More than 700 systems have been installed worldwide since the early 70's.

 

In Australia, over 100 systems using AIRVAC technology are successfully in operation.

 

The Valve

 

The heart of the system is the DN80 AIRVAC Vacuum Interface Valve.  Proven reliability in Australian conditions based on 30 years of operating experience and continual research and development.

 

Approvals

 

AIRVAC vacuum systems comply fully with the following Australian Standards:

 

• AS4310:2004 - DN80 Piston Type Vacuum Interface Valves for Municipal Sewer Systems
• WSAA Vacuum Sewerage Code of Australia WSA 06-2008

Why WaterCon?

 

WaterCon has been involved with AIRVAC Vacuum Systems in Australia for over 10 years.

 

We have been involved in the design and construction of 90% of the systems in Western Australia, and many systems in the other states of Australia.

Advantage AirVac

Reduced Excavation and Pipelaying Costs

The vacuum mains can be laid with minimum cover, and do not need to be layed on a grade toward the pump station. This makes vacuum sewerage the right system where the following conditions exist.

• Rock
• High Water Table
• Unstable Soils
• Restrictive Construction Conditions

 

Vacuum mains can be common trenched with other utilities and use smaller diameter pipes compared to and equivalent gravity sewers .

 

No manholes or access chambers are required for vacuum mains.

 

High pipeline velocities mean less blockages and better aeration and mixing of wastewater. This pre-treatment reduces treatment at the WWTP, therefore reducing wastewater system operating costs.

 

Leaks cannot go unnoticed, and any leaks do not discharge waste water to the environment.

 

Because the mains are shallow, and operate under vacuum there is little chance of infiltration, and thus permitting the use of smaller treatment plants, or increasing the effective capacity of existing ones.

 

Enhanced Safety for the System Owner and Operators

 

Minimal risk of operator exposure to sewer gases like CH4 and H2S.   Vacuum mains are less likely to suffer blockages and do not require cleaning. There are no deep chambers, and in most cases no confined space entries are required to maintain the system.

 

Customer Benefits

 

Power is only required at the pump station. The collection pits are usually located outside the customers property.

 

There is no noticable difference to the customer, as traditional gravity transports the waste water from the customers sewer to the vacuum collection pits.

Environmental Benefits

 

Minimal impact during construction in ecologically sensitive developments and eco-villages.

 

Lower water consumption when used in conjuntion with vacuum toilets.

 

Virtually impossible for discharge to environment through leakage as the system is operating under vacuum.

 

Two pipe systems  are possible for separate transport of urine and black waste using urine separating toilets, thus allowing greater re-use possibilities.  This also reduces harmful nutrients from entering the environment.

How does the Airvac Vacuum Sewerage System Work?

 

Vacuum Sewerage Systems use air to provide the energy to transport the wastewater from the collection pits to the pump station.

 

Wastewater leaves the customer's property via traditional gravity main to the collection pit. The collection pit contains the AIRVAC Vacuum Interface Valve, which controls the level of wastewater in the pit, as well as admitting the correct amount of air into the vacuum main, critical to the operation of the system.

 

The wastewater is transported to the vacuum pump station, where it is collected in a vacuum vessel. It is then pumped under pressure to the treatment plant. Vacuum pumps maintain the correct vacuum in the vessel and vacuum mains to allow the system to continue operating.
