If your project has any of the following conditions, then vacuum sewers are the solution for you:

• At Least 75 Connections
• Rolling Hills with Small Elevation Changes
• High Groundwater Table
• Restricted Construction Conditions

• Unstable Soils
• Flat Terrain
• Rock
• Sensitive Eco-system

AIRVAC’s typical project has one or more of the above difficulties, most likely has experienced failing septic tanks, and is in a suburb of a city. However, having completed projects in every imaginable environment, AIRVAC has been able to customize its product to fit virtually any customer need.

There are construction advantages as well as operation advantages to using vacuum sewers. These advantages include substantial reductions in water use, material costs, excavation costs and treatment expenses. In short, there is a potential for overall cost-effectiveness.

 

"AIRVAC is an excellent system if you have flat ground, high groundwater, or rock." - Skip Grodt

"Our AIRVAC system was only one-third the cost of a gravity system and O&M is less." - Miles Beach

Construction Advantages

Smaller pipe: Small PVC pipe sizes (3", 4", 6", 8" and 10”) are usually used.

No manholes: Manholes are not used in vacuum sewers.

Field change ease: Field changes can easily be made as unforeseen underground obstacles can be avoided by going over, under or around them.

Less excavation: Installation of smaller diameter pipes at shallow depths eliminates the need for wide, deep trenches reducing excavation costs and the duration and severity of community/environmental impacts.

Only one source of power: Power is only required at the vacuum station. No on-lot power demands exist at valves.

Operation Advantages

No blockages: High scouring velocities are attained, reducing the risk of blockages and keeping wastewater aerated and mixed.

Operator friendly: Elimination of the exposure of maintenance personnel to the risk of H2S gas hazards.

Environmentally friendly: The system will not allow major leaks to go unnoticed, resulting in reduced environmental damage from exfiltration of wastewater.

Smaller treatment plants: The elimination of infiltration permits a reduction of size and cost of the treatment plant.

Pretreatment: The air/sewage mixture enters sewers at high velocity, and the air provides some pretreatment to the sewage inside the vacuum sewers.
