VİAVAC vacuum sewers are sanitary sewers that use a mechanized method of collecting wastewater at high velocity using negative pressure (vacuum). VİAVAC sewers are cost-effective alternatives that provide permanent sanitary sewer systems to communities that do not have or have a collapsed gravity or combined (sewerage and storm water) sanitary system. VİAVAC vacuum sewers are environmentally friendly and easy to install. VİAVAC vacuum sewer systems are designed, built and installed by Viatek using Vacuflow®technology which ensures the highest level of vacuum sewer system performance.
HOW DOES IT WORK?
VACUUM SEWER SYSTEM TECHNOLOGY
AVİAVAC vacuum sewer system works like any other sewer system. Houses drain their wastewater into the VİAVAC valve pit via traditional gravity pipe. Up to 4 houses are connected to the valve pit installed in the street.
When approximately 10-12 gallons of wastewater accumulates in the VİAVAC valve pit, the VİAVAC Vacuflow valve opens and pushes the water and solids into the vacuum main. Wastewater travels at approximately 18 feet per second in the PVC vacuum main until it is reaches the vacuum tank in the VİAVAC vacuum station. The high speed flows within the PVC pipes eliminate the possibility of clogs and sedimentation.
A VİAVAC vacuum sewer system consists of a VİAVAC vacuum station, a PVC piping network that is buried in shallow trenches under the streets and VİAVAC valve pits.
The VİAVAC valve pit package consists of a 63 or 90 mm Vacuflowinterface valve assembly with by-pass, heavy duty polyethylene plastic pit and HS-25 plastic cover with frame. The valve pit is HS-25 traffic-rated and can serve up to four properties Learn More
A typical VİAVAC vacuum station consist of vacuum pumps, sewage pumps, a collection tank and a control panel. Learn More
If your project has any of the following conditions, then vacuum sewers are the solution for you:
• At Least 60 Connections
• Densely populated communities
• High groundwater table
• Flat terrain
• Restricted construction conditions
• Unstable soils or rock
• Very cold, humid and dry climates
• Sensitive eco-system
• Failing septic tanks or gravity sewer system
At the vacuum station, vacuum pumps operate in short intervals to maintain a constant level of vacuum in the entire system. When wastewater in the collection tank reaches a predetermined level, sewage pumps transfer the contents via a force main to the wastewater treatment plant or to an existing gravity manhole.
