To save yourself from the need to inhale smells from cesspools, it makes sense to buy a septic tank for a private house, having previously studied its features and giving preference to a specific variety.

With the constant residence of a large number of people in the territory of a private house, the sewage pit simply can not cope with the task and it will require an assistant, whom the septic tank can become.

What is a septic tank

Private houses or country cottages differ from ordinary apartments in that there is no central sewage system and the use of a special device will be required to remove household water. A septic tank is a sealed container in which liquid waste accumulates. The biological treatment function is available for some models, but they cannot be ranked as full treatment plants.

What is it needed for

The owners of country houses in the arrangement of the sewage system must ensure the treatment of wastewater, taking into account sanitary standards and soil characteristics. A reliable option will be a septic tank, also called a sump, whose function is the accumulation and purification of waste leaving the room. He passes impurities through himself, not allowing him to penetrate the soil. Before you make a septic tank in a private house, you should understand its structure and work.

Device

During the construction of the cottage, special attention should be paid to the arrangement of autonomous sewage, since there is no central project. The device of a septic tank in a private house allows you to solve problems with the removal of household waste and its treatment. The work is carried out in three stages:

  • Sewer drains leaving a private house are collected in sealed plastic containers at a local sewage treatment plant.
  • Inside the septic tank, particles are divided into heavy and light. The former settle at the bottom of the well, while the latter enter the next compartment.
  • Aerobic cleaning is not always possible, so often anaerobic. Sewage is filtered, and the resulting methane is discharged using the exhaust pipe..
