Sand Filter
Sand filter systems are one of
the most common types of septic systems in greater than 35% clay areas
that have limited permeability. This system uses 3 different types of
material over the depth of 50 inches to achieve its 98% clean water
discharge. Followed by a chlorine contact tank before finally
discharging to the surface.
Trench System
A trench is defined as a soil
treatment and dispersal system, the absorption width of which is 36
inches or less. Trenches are narrower than they are wide, no wider than
three feet, and are laid out along the contours of the soil. The method
of distributing the septic tank effluent can be either pressure or
gravity.
Seepage Bed
A seepage bed system is a wide
area prepared to accept septic tank effluent. It is created below the
surface of the soil and built the same way as a trench system. Seepage
beds treat the effluent effectively as long as they are located in
appropriate soils. They can use either gravity or pressure distribution.
The construction of a seepage bed is essentially the same as that for a
trench, except the bed is wider.
Aerobic System (Aereation System)
One of the more unconventional
types of septic systems is the aerobic design. The system is equipped
with a watertight tank that has an aeration chamber. Waste is broken
down by bacteria in the aeration chamber. These systems are capable of
producing cleaner waste water, so they are commonly used in sensitive
environments. Click Here for More Information...
