Excavate a hole that will allow for
a minimum 275mm gravel base
beneath the Puraflo modules
(taking note of water table and
other site conditions). Puraflo
modules can be installed above
ground or so that the lids are level
with the ground level but the lids
must never be covered.
The gravel base must extend
minimum 500mm beyond the
footprint of the Puraflo modules
on all sides.
Excavate a hole that will allow for a
minimum 300m gravel base beneath the
Puraflo modules (taking note of water
table and other site conditions). Puraflo
modules can be installed above ground or
so that the lids are level with the ground
level but the lids must never be covered.
The size of the area covered by the gravel
base is determined by the following
formula:
Area = PE * T * 0.125 (EPA CoP)
