| All septic systems are either anaerobic or aerobic type
systems. Most homes built prior to the early 90’s have a conventional (anaerobic)
system. In recent years many homeowners are spending the extra money to install an aerobic
system. There are advantages and disadvantages to both systems. |

Conventional septic systems are the least expensive type of
system to install and maintain. They are designed to settle waste in the bottom of a tank
that is buried in the ground. Bacteria then processes the waste. Effluent (liquid waste)
is drained out into lateral lines that are buried in crushed rock below the ground. The
earth cleanses the contaminated effluent. One major problem with this
type of system is that clay soils are dense and will not absorb the effluent.
It is recommended that the tanks be pumped and inspected approximately every 2-3 years. |
| An aerobic system has the ability to process waste
within the system at a very high rate. Once the effluent has been cleansed
and chlorinated it can then be
used to water the yard. These systems are popular in areas that have heavy amounts of clay
in the soil or on small lots that cannot support enough lateral line to effectively
operate a conventional system. In order to have an aerobic system installed, most areas
require that you maintain a quarterly maintenance schedule with a licensed professional. |
