Perforated and slotted HDPE pipe is the best option for applications which require water drainage, leachate systems, cable protection, ducting, and landfill gas dissipation.

Perforated pipe is used to speed up the removal of water from the ground or to let rain water soak into the ground. These perforated pipes are shop-fabricated with holes or slots in them to collect subsurface water and move it to a better place for discharge. Typically holes should be roughly circular and set up in rows that are parallel to the pipe’s axis. There are full, half, and one-third perforations for perforated pipes. The perforations need to be in the valley of the outside surface.
