Siphon rainwater drainage system is a new technology which is developed very fast in Europe, American, Japan, South-American, Asia and Africa countries. It is a more scientific and advanced technology, can be used on big construction building like factory, workshop, warehouse and public building. The inner drainage system has obviously advantages comparing with the traditional gravity current drainage system.

System Composition
The siphon drainage system is mainly composed of rainwater head, fastening systems,HDPE pipe and the corresponding design
software.
Tengyuan can supply municipal engineering pipe, dredging engineering pipe, HDPE Gas Pipe, Power Engineering Pipe, Mining Pipe and agriculture irrigation pipe, etc. Integrity is the foundation of us, as well as the guarantee for enterprise's sustainable development.
System Advantages
Compared with the traditional gravity drainage system, the siphon drainage system has advantages as follows:
Features:
level is0 (the lowest)and no mildew material. Compared with some other commonly used plastic material, PE is much mildew resistance and it could be used for a long time without fouling.
