MoundBuster is an innovative wastewater disposal field uniquely designed
to lower the mounding profile and footprint of conventional
disposal field systems. The MoundBuster System has the smallest
footprint in standard configuration of any system approved
in Maine. MoundBuster is provisionally approved for use in
the State of Maine and it is approved to be used only with
the OxyPro advanced treatment unit (ATU).
The MoundBuster size is minimized because the OxyPro ATU provides
a high degree of wastewater treatment. Conventional systems
send organic-rich, oxygen-poor water to the disposal field.
Anaerobic bacteria consume the organic material and cause
clogging in the disposal field. Since conventional disposal
field sizing is based to a great extent on that clogging,
disposal fields need to be large to take into account the
slow permeability of the clogging zone surrounding the disposal
field. The OxyPro ATU produces effluent with very little organic
material and a high oxygen content. This helps to prevent
anaerobic bacteria from becoming a problem in the disposal
field. Since the MoundBuster receives relatively clean wastewater
from the OxyPro ATU unit, the MoundBuster disposal field can
be sized based primarily on the permeability of the natural
soil.
An additional feature of the MoundBuster disposal field that
is different than most conventional systems is its flexibility
on difficult sites in areas where the disposal field needs
to curve around shallow bedrock or water table features requiring
non-rectangular shapes. Since the MoundBuster pipe is flexible,
many disposal field shapes are possible. Another feature of
flexibility for the MoundBuster system is the ability to design
the system around small areas of non-permitted soils or shallow
bedrock by substituting non-perforated pipe where a non-permitted
feature underlies a portion of the system.
