Septic Systems Work and The Process for Septic Installation
Septic System is composed of only two basic components:
a septic tank which allows the settling of solids and the
retention of floating material (scum) and a disposal trench or
field, which allows the wastewater to infiltrate into the soil.
septic tank receives sewage from the house. The tank is typically
constructed of concrete, however older systems may have a steel
tank. The septic tank has an inlet opening and outlet opening
near the top of the tank. As sewage enters the tank an inlet baffle
directs the inflow towards the bottom of the tank. Solids settle
to the bottom of the tank and form the sludge layer. An outlet
baffle extends down into the clear liquid between the sludge and
sewage enters the tank, an equal volume of water is displaced.
This water (septic tank effluent) flows up through the outlet
baffle and out of the tank to a disposal system. If the property
calls for a Pressure Dose System, a dosing tank will be added.
A dosing tank is a concrete tank with a pump that receives septic
tank effluent and pumps it to the disposal field.
The disposal system may include a gravity bed, pressure dose or
disposal trenches. Disposal beds and trenches use a distribution
box or distribution manifold to evenly proportion the effluent
amongst perforated laterals that allow effluent to flow out of
the system and into the surrounding soil. A typical disposal bed
consists of 96" of suitable select fill meeting the state standards,
17" of cleaned crushed stone, distribution laterals, distribution
box or distribution manifold, filter fabric and a 9" minimum of

Of A Septic System
to pump out the septic tank when it is needed is the most frequently
documented cause of septic system failure.
Standards for individual Subsurface Sewage Disposal Systems require
that any septic system, which was approved for construction, and
any existing system which was altered or repaired after January
1, 1990, must be inspected annually if the septic tank has not been
pumped out within the previous three years.
failure to pump out a septic tank when it has reached its capacity
to retain scum and sludge will result in the scum and solids being
carried out of the septic tank and into the disposal field. If this
condition is allowed to continue, the scum and solids will soon
clog the disposal field. If this happens, sinks and showers may
not drain, toilets may overflow and the homeowner's lifestyle will
be seriously disrupted. Costly and time-consuming reconstruction
of the disposal field is usually the only solution when this happens.

is a septic system? A septic system is a subsurface wastewater
treatment and disposal system. In most circumstances a septic system
will serve only one individual house or building. The sewage from
the house enters the system through a building sewer and is treated
before being discharged into the ground. Modern systems include
a septic tank to retain solids, greases and fats and a disposal
field to allow the liquid (effluent) to flow into the ground.
is a sand mound? A sand mound is a system in which the disposal
field has been elevated above the original ground surface to account
for a high water table, shallow bedrock, or other type of site constraint.
A mounded system will normally include a pump tank and pump to lift
the effluent up to the raised disposal field.
a sand mound more prone to failure than an in-ground system?
No. Although a sand mound does include the pump and its associated
electrical connections, a properly designed and installed sand mound
is no more prone to failure than a conventional septic system.
is a cesspool? This is the simplest type of subsurface wastewater
treatment disposal system. A cesspool is common for homes built
prior to 1930. The system consists of a pit that has been constructed
out of field stone or concrete block. Sewage enters the pit through
the building sewer. The liquid in the pit rises while water is added.
The water level drops as water flows out of the cesspool and into
the surrounding soil. Cesspool are normally quite deep, and the
pressure from the water column within the pit forces water through
the opening into the soil.
often should I pump my septic tank? You should pump your septic
tank every 2-3 years under normal circumstances. If you have a large
family you should pump the septic tank more often to prevent solids
from flowing out of the tank and fouling the disposal field.
is a baffle? A baffle is an internal component of the septic
tank. An inlet baffle directs all sewage towards the bottom of the
tank. An outlet baffle prevents floating scum and grease from escaping
the septic tank and accumulating in the disposal field.
are septic systems in New Jersey so expensive? A combination
of factors including design requirements and standards (NJAC 7:9a),
subsurface soil conditions, materials costs, and market influences
causes the price for a new septic system in New Jersey to approach
$ 30,000 - $ 40,000.
