Hdpe siphon pipe
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.
