Insights Diagram
of typical Septic System
 Leach
Lines:
This system consists of one or more trenches, 18 to 36 inches in
width, a maximum of 100 feet in length, and containing 12 to 36 inches of gravel
beneath a single perforated pipe through which sewage effluent seeps into the
surrounding soil.
Seepage Pits:
This system consists of one
or more covered circular excavations, four to six feet in diameter with an interior
lining of six inches of gravel and brick or concrete liners allowing effluent
to seep into the surrounding soil. 
Infiltrative
Chambers:
This system consists of semi-circular chambers installed contiguously
with the open portions on the ground. The design infiltrative surface area of
this system is reduced to seventy percent (70%) of the area required for a conventional
leach line.
Leach
Beds:
This system consists of multiple perforated lines installed in an
excavation with a minimum 36 inches in width, maximum of 100 feet in length and
containing 12 to 36 inches of gravel beneath a system of perforated pipes through
which sewage effluent seeps into the surrounding soil. The size for a leach bed
is fifty percent (50%) greater than the area required for a conventional leach
line.
Enhanced system:
A non-conventional Onsite Wastewater Treatment
System (NOWTS) that utilizes a supplemental treatment technology in conjunction
with a conventional dispersal system of leach lines or seepage pits or a combination
of both to allow effluent to seep into the surrounding soil.
Alternative
System:
A non-conventional Onsite Wastewater Treatment System that utilizes
a supplemental treatment technology in conjunction with pressurized drip tubing
or other approved sub-surface, non-conventional means to allow effluent to seep
into the surrounding soil.
