Elegant HDPE Perforated Pipe is used to accelerate the removal of subsurface water in soils or to allow storm water to percolate into the soil. HDPE pipes are produced with slots or perforations to collect and convey subsurface water to a more favorable location for discharge. The perforations shall be approximately circular and arranged in rows parallel to the axis of the pipe. Elegant HDPE perforated Pipes are available in Full / Half / 1/3rd perforation. The locations of the perforations shall be in the valley of the outside surface.
HDPE perforated and slotted pipe is the preferred material for water drainage, leachate systems, cable protection, ducting, and landfill gas dissipation.
Perforated pipe systems can be thought of as long infiltration trenches or linear soakaways designed for both stormwater conveyance and infiltration. They are underground stormwater conveyance systems designed to reduce contaminant loads to receiving waters by attenuating runoff volume.
The trench should be about 2 feet deep and sloped downward in the direction you want the water to flow. Cut any roots that are growing in your French drain.
Perforated pipe, on the other hand, is identical in shape to solid pipe, but has holes or slots cut into it along its entire length, allowing water to enter and exit freely.
A perforated pipe has small slots or holes that allow water to easily exit or enter. Because of its ability to absorb and drain water, this type of pipe is commonly used for underground drainage systems and other outdoor applications.
