What are septic tanks and what is the principle of their work

A septic tank is a local device that is connected to the local household sewer system. A septic tank is necessary in order to collect, settle and purify waste water that is discharged from the house through this sewer. These devices are installed in places where there is no centralized sewage infrastructure. In most cases, these are country houses or summer cottages and a huge number of entire settlements in the rural outback, where there is no sewage system.

The choice of the right septic tank depends not only on the volume of effluent, but also to a greater extent on the local natural conditions. Therefore, for a competent assessment of a future purchase, you need to understand a little about the device and the principles of operation of various types of installations. Any septic tank existing today is a reservoir that can be divided into two or more departments. The general principle of the installation is as follows:

• through sewage pipes, sewage with sewage enters the first tank, which acts as a sump. In it, heavy components sink and accumulate at the bottom. Light fractions and fats accumulate on the surface of the water;
• with the help of an overflow, this liquid enters the second compartment, where their further settling and decomposition of organic matter occurs when bacteria act on it;
• the last section allows you to purify the water so that after passing through the filtration fields it can be safely poured into the ground, infiltrating through which it is completely cleansed of all harmful substances and odors.

What is the best septic tank for a summer residence: the principles of choice

Before choosing a septic tank for your summer cottage, you need to draw up a small technical task that would give answers to the following questions:

• how much liquid is discharged from the house per day. To do this, you need to know the number of family members living in the household and possible guests. Household appliances that use water installed in the house and their average daily productivity are taken into account. This includes a washing machine and dishwasher, as well as showers and taps;

Choosing the required septic tank performance

Before buying or an independent device of any septic tank, it is necessary to determine the required performance. This indicator determines the amount of waste liquid that the installation is able to process per day. The number of compartments and their volume depends on it.

Useful advice! According to building codes and regulations, the septic tank should hold as much water as it can be discharged by households in three days. It is not rational to use a smaller volume of a septic tank, since the water simply will not have time to be filtered and it will have to be constantly pumped out.

The optimal depth of placing a septic tank in the ground

It is generally accepted that if less than 1 m³ of wastewater is generated per day, there is no need for multi-chamber septic tanks. Two-chamber models are installed when this indicator is reached from 1 to 10 m³ / day. If the indicator is even higher, then there is a need for a three-chamber installation.

How soil properties affect the choice of a septic tank

Modern treatment devices operate in conjunction with effluent filtration fields.However, their construction is not always possible due to the fact that the soil is not suitable for this. Clay soils cannot pass water through themselves, and, therefore, are not able to filter it. The high occurrence of groundwater (closer than 150 cm from the surface) makes it impossible in principle to arrange filtration fields.

It is a ready-made purification unit, when passing through which water becomes completely safe for the environment and can even be used for watering plants.
