Description

VACUUM DRAINAGE SYSTEM WITH GERMAN TECHNOLOGY OF AQSEPTENCE GROUP

WHAT IS VACUUM DRAINAGE?
+ Is the domestic collection system – replaced solution for common drainage system in special conditions.
+ Vacuum drainage is the difference between air pressure and gravity, is the thrust force to quickly transport wastewater in the network from the collection pits/sumpits  to the central collection tank and then to the discharged point.

Characteristic of Vacuum drainage:
+ Domestic wastewater collection system;
+ Install easily in small, medium residential area, industrial one, commercial one or mixed one;
+ Advanced technology, environment-friendly system, safe and friendly with operator;
+ Can replace to the traditional gravity drainage system in difficult conditions;

Application of vacuum drainage: 
+ Vacuum cleaning equipment system in the building;
+ There is the high groundwater in the building at plain;
+ Rural area / low population area;
+ Water protection;
+ Nature conservation;
+ Areas affected by tides and floods;
+ Coast / Island;
+ Marina / wharves;
+ Villa / Beach resort;
+ Obstacles in the ground;
+ Poor soil conditions (rocky / sandy soil, avoid digging deep, swamp)
+ Minimal construction impact (traffic, buildings, narrow roads)
Advantages of vacuum drainage: 
- Completely closed system: no leakage, no odor, no intrusion of rainwater, groundwater as well as wastewater will not seep into the ground and groundwater, no need to rinse the pipeline.

- There are no manholes on the network, each building does not need a septic tank, so there is no smell;
- Do not flood the drainage system;
- High flow velocity (> 5m/s); no settling, self-cleaning, no water stagnation, no dredging of sewers and tunnels periodically;
- Suffer fluctuation of flow;
- Need one central vacuum station, no need lift pump station;
- Small pipe diameter (D90 – D250); HDPE (SDR11) or PVC (PN10), not occupy much area, can be placed together with other technical pipes in the same digging;
- Save cost and build fast and easily because the ditch is shallow and small);
- The system is flexible because the installed wastewater pipeline does not depend and  influenced by the topography, can change depending on the conditions of the construction site;
- Decrease operation & maintenance cost
- Decrease the wastewater treatment cost because rainwater can not flow into the piping network
