Individual Sewage Disposal System: An individual sewage disposal system is a
subsurface sewage disposal system designed and constructed to treat sewage in a manner
that will retain most of the solid waste in a water-tight tank and to discharge the liquid
portions to an adequate disposal area.
Septic Tank: A septic tank is a water-tight receptacle which receives the discharge of
sewage from a building sewer or part thereof, and is designed and constructed so as to
permit settling of solids from the liquid, digestion of organic matter by detention, and
discharge of the liquid portion into a disposal area.. The tank is generally designed to
provide a 2-day retention time for wastewater  settling to occur. Heavy solids sink to the
bottom forming a layer of “sludge” while light solids and fats/grease form a floating “scum
layer”.
Disposal Trench: Disposal trenches are shallow ditches with vertical sides and flat
bottoms partially filled with a satisfactory filtering material in which a single distribution line
has been laid, covered with top soil and a suitable vegetative cover.
Disposal Bed: A disposal bed consists of an area from which the entire earth contents
have been removed and the excavation filled with a satisfactory drainage & treatment
material in which distribution lines have been laid and the entire area covered in topsoil and
a suitable vegetative growth.. The size of the disposal bed will depend on the anticipated
volume of water to be produced from the home and the soil conditions at the site.
Seepage Pit: A seepage pit is a covered pit with open jointed lining through which septic
effluent or laundry waste may seep or leach into the surrounding soil.
Distribution Box: The distribution box lies between the septic tank and disposal area.
And serves to evenly distribute the wastewater evenly amongst the drain lines. Ensuring
even distribution of the wastewater is crucial in maintaining the longevity of the disposal area.
Conventional Treatment Systems: Refers to the standard gravity flow design, which
consists of a septic tank, a distribution box and a drainfield (disposal bed).
Mounded and Filled Systems:  These systems are common solutions to overcoming
shallow depth to ground water table or other restrictive features, where site conditions allow
for the use of conventional treatment systems. The onsite treatment components are
installed within the mound of fill. Some systems require an effluent pump & pump tank be
installed.
Advanced (Alternative) Treatment Systems: Advanced treatment systems differ from
conventional systems in a number of ways.  The primary difference being that they further
treat the wastewater before it is dispersed to the soil environment. Reducing the “strength” of
the wastewater or solids, fats and greases that are suspended in the effluent.
