Vacuum Sewer System
Features
This unmanned automatic system detects water level with no power supply, and collects sewage and
wastewater to the vacuum pump station using vacuum valve pike and vacuum line which are automatically
operated and then transfer them to the intercepting sewer or wastewater treatment plant.
Features System
Economy
- The construction period is shortened and cost saved due to narrow and low excavation.
- Vacuum valve operates without power supply and maintenance costs are low.

Eco-friendly
- Pollution groundwater and land is prevented due to improved water tightness.
- Leakage of odor from manholes and vacuum line prevented.
- No need to clean the pipe due to fast flow
Applicable Area
- A wide and flat area where the depth between the ground and the site where the pipe is located is deep
- A soft ground area where the pipe is likely to ve sunk
- A bedrock area where the building construction is hardly made
- An area where lost of object are laid underground
- An area where it is hard to maintain the minimum flow rate and the dredging operation is frequently made
- An area where the wastewater source is located lower than theroad
System Process
While it is maintained vacuum inside the pipes, when the vacuum valve is opened and air flows in, sewage is collected using the pressure difference with the atmosphere.
