1, Rainwater infiltration pipes made of PE solid wall or PE winding structure wall are better options, in order to be welded with inspection wells made of the same material.
2, The diameter of the holes is not less than 150mm, according to drainage flow.
3, Plastic pipe with hole rate of 1% to 3%.

When it rains, the harvested rainwater enters the system and is stored in the gravel layer, and infiltrated through sides and bottom. Rainwater that excess the designed amount flows in the pipeline, into the municipal rainwater pipe network system. When it stops, the water inside pipeline will keep infiltration for a certain period of time.
