When choosing a septic tank, try to calculate how much water you will spend on a daily basis: at a rate of more than 5 cubic meters of a septic tank must total at least 15 cubic meters of volume. Thus the septic tank into a first chamber should account for about 75% of the wastewater.

In theory it is possible to arrange a septic tank made of brick, concrete, reinforced concrete or precast concrete. Often still use concrete.

Dirty waste water sewers for 1 enters the chamber septic tank. Here begins just two cleaning process. Origin -separated sewage fractionation (working force of gravity).
The second - the process of anaerobic fermentation involving bacteria from the wastewater.

Due allocated fermentation gases. Formation of gas bubbles accompanied by the release, which results in water movement (water in the chamber begins to move in a circle), causing drains further separated into fractions (separation occurs drains).

Primarily purified water is collected in the center of the first chamber, from where it proceeds to the next compartment, where the biofilter. When passing through the biofilters, the water is filtered and subjected to bioprocessing. In the second compartment is located tail pipes through which drains go to the Infiltrator.
