Petro-Pipes® are used when a vertical drain is not an option.  Poor draining soil,
high water table, and other reasons might render a vertical drain down into the
ground impossible.  In this situation, discharge of water from a containment area can
still be accomplished through a
Petro-Pipe®.  A berm or curb can be installed to hold
back rainwater that might also contain oil.  Installing several
Petro-Pipes® through
the berm or curb, or through a wall, will allow water to pass through while trapping the
oil.  As with the
Petro-Plug®, oil cannot get through the Petro-Pipe®.

Petro-Pipes® are typically used in spill containment applications where Petro-
Barriers
TM won’t work due to lack of adequate drainage.  Since the driving force
behind water drainage (i.e. gravity) works best up and down, not sideways,
Petro-
Pipes®
are not as efficient at moving water as a similarly sized Petro-BarrierTM.  
Therefore, more surface area is required using
Petro-Pipes® than when using
vertically-draining barriers.  Plan to install the
Petro-Pipes® at a downward angle to
obtain at least some amount of gravity “pressure”.  A 25 degree minimum slope from
inlet to discharge is recommended for flow rates of 2.5 to 3 gls.  per minute.
