Airvac’s vacuum sewer collection system is sealed from valve pit to vacuum station.
Airvac’s completely sealed vacuum sewer collection system prevents infiltration and inflow of groundwater from the valve pit to the vacuum station, protecting the environment from exfiltrating wastewater. It is one of the most environmentally sound solutions available.For vacuum sewer collection systems, if leaks were to occur, they would not result in sewage spills. Instead, air would enter the pipe and be immediately detected. Standard equipment in a vacuum station automatically notifies operating personnel if this occurs.
​
Energy conservation
Airvac vacuum sewer collection systems only require one power source, located at the vacuum station. Because vacuum valves are pneumatically operated, no power source is required by the homeowners.A single vacuum station can often serve the same area that would traditionally require 6-7 lift stations, minimizing the building footprint and reducing energy use.Because the vacuum system is closed from
the valve pit to the vacuum station, inflow and infiltration are eliminated. Energy is not expended transporting or treating excess water from storm events and treatment plant demand is eased.

Vacuum Pump Modulation
Modulation is a patent pending program logic that improves the manner in which your vacuum system functions. Previous designs required vacuum pumps to turn on at 16”Hg and off at 20” Hg in response to vacuum levels within the vacuum system.
The modulation sequence controls the speed of the vacuum pumps to maintain a tighter vacuum range and speeds up and slows down depending on the demand of the vacuum system. It is unusual for the pumps to ever operate at full speed.
Since the pumps are not turning on and off as frequently and are running at lower speeds, modulation also significantly reduces the overall power consumption and creates less heat and noise.
Modulation has proven so effective that capital outlay can be paid back in as little as eighteen months through energy savings alone.
Vacuum Pump Modulation Benefits
-
Reduction of up to 35% of current power usage.
-
Noise and heat reduction provide safety and comfort to operators.
-
More consistent vacuum pressure throughout the system results in a more reliable system.
-
Improved end-of-line vacuum levels.
-
Potential for energy grants.

Wireless Monitoring
Airvac’s wireless monitoring system tracks trends, providing operators the ability to proactively operate and maintain your vacuum sewer collection system.
Features
-
Airvac’s Wireless Monitoring System allows operating personnel to monitor each valve pit in real time
-
A trend feature tracks the operation of each valve pit and notifies the operator of system imbalances
-
The exact location of a problem can be identified
-
Pertinent data can be collected and saved to allow for analysis and adjustment if necessary
Airvac’s wireless LoRaWAN monitoring system provides operators the ability to proactively operate and maintain your vacuum sewer system. Airvac’s technology tracks trends and fine-tunes the operation of the vacuum system, improving its efficiency. The monitoring system notifies operators of active alarm conditions and identifies abnormal conditions as soon as they occur.
By including Airvac’s optional S.M.A.R.T. (Strategic Monitoring for Advanced Remote Transfer) system, the artificial intelligence automatically adjusts the vacuum system to prevent abnormalities. More clearly, Airvac’s patented SMART system provides your vacuum system with intellectual capabilities.
Vacuum Station
The vacuum station is the heart of an Airvac Vacuum System.
Airvac Vacuum Station considerations:
​
-
Where protection against flooding is a concern, the Airvac skid(s) can be housed in a two story structure with the vacuum pumps and the control panel located on the top floor and the collection tank and sewage pumps on the lower floor.
-
For customers who need a small vacuum station for an initial phase of a larger system, Airvac can house the vacuum station in a shipping container and make it available on a short-term lease basis.
-
Prefabricated options are also available.
​
Engineered Custom Vacuum Stations
​
Engineered custom vacuum stations are ideally suited for larger systems with more than 550 connections and peak flows greater than 350 gpm. With an engineered custom vacuum station, Airvac provides all the internal components on a skid(s) which are housed in a building or other structure that is custom designed by an engineering firm.
​
PacVac Vacuum Stations
PacVac vacuum station models are ideally suited for small to medium-sized projects serving less than 550 connections and/or peak flows less than 350 gpm. Generally, the mechanical and electrical components are located on skids including the vacuum pumps, sewage pumps, collection tank and control panel. The skids are housed in a prefabricated building that can be supplied by Airvac depending on which model PacVac is used. The prefabricated building can either be installed on-grade or on a contractor-built basement vault.
Solar Light Monitor
Easily identify the affected valve pit if an issue should occur.
Solar Light Monitor Benefits
​
-
Activates if high sewage sump levels occur.
-
Flashes if the valve remains open longer than 15 seconds.
-
Allows operators to easily identify which valve pit is affected.
-
Is easily visible from a long distance.
​
A solar light monitor is mounted on the air terminal and connects to the sump breather and the vacuum valve. The solar light monitor can signal a high sewage sump level via the breather or a valve failure via the vacuum valve. The light is easily visible from a long distance, avoiding the need for operators to physically check every vacuum valve in the system.
S.M.A.R.T system
Strategic Monitoring for Advanced Remote Transfer.
System Benefits
​
-
Automatically monitor and control your entire vacuum system.
-
Perform automatic real-time system adjustments that previously required human interaction.
-
Activate vacuum valves remotely.
-
Control vacuum pump modulation.
-
Wirelessly monitor valve pits.
-
Access controls on a mobile device.
​
Controlling a vacuum system’s behavior typically has been a reactive process where operators analyze system data and make adjustments accordingly. Or a problem may occur requiring an operator’s attention prior to any adjustment being made.
With Airvac’s S.M.A.R.T. System, operation of the vacuum sewage system is taken to the next level. S.M.A.R.T. not only monitors the sewage system, but automatically makes real-time adjustments to optimize system hydraulics. This proactive approach of controlling the vacuum sewage system’s behavior results in increased system efficiency, prevents problems from occurring, increases end of line vacuum levels and reduces operation & maintenance costs.
Proactive not reactive
Potential problems are not only identified but adjustments are made automatically to correct them.
A More Efficient System
System imbalances can be quickly overcome, resulting in a more efficient system, fewer callouts, and lower power bills.
Built in Purge Cycle
A “purge” cycle can be programmed into the logic controller that will automatically clear the vacuum mains at predetermined times to ensure that waterlogging of the system during critical times will not occur.
Airvac is Connected 24/7
Airvac specialists can monitor your system in real-time providing another set of eyes for the system operator.
System Updates are Pushed Automatically
Airvac automatically pushes new programming updates remotely to keep the S.M.A.R.T. System current.
