To increase the level of comfort during the operation of a private house or summer cottage, it is required to engage in fencing arrangement of the sewage system. Such tasks should be solved without fail, and for this there are several ways, one of which was the installation of a plastic septic tank.

Due to the rapid development of modern technologies, it can solve any everyday issues with the help of simple, but nevertheless effective measures. Not so long ago, to equip a septic tank, it was necessary to create heavy concrete or brick structures.

But at the moment, a high-quality sewage treatment plant can even be made of plastic, and when compared with more massive structures, such containers perfectly fulfill their task and at the same time much easier.


The question of where and how to dispose of waste products has always been exciting and relevant in private homes. To solve such problems, they began to use volatile septic tanks, which differ from the usual ones in that they do not harm the environment, are quite economical, do not need frequent maintenance and recharge from a source of electrical energy.

Important! Tanks for septic tanks are made of high-strength plastic, while the material is 100% environmentally friendly, has a high level of resistance to any type of chemical attack.

Such raw materials will not decay, and besides this, the material will not crack and rust.

It is simple and convenient to use, and cleaning and pumping is done using a sewer truck. Plastic tanks for underground disposal can be used for the disposal of waste, as well as diesel fuel and water, as indicated by the relevant certificates.

Due to the fact that only welding technology without a seam is used in the manufacture of a plastic septic tank for sewage, the device is sealed. Typically, products have a body reinforced with ribs, which will perform a protective function, and in this case the material will be protected from overload. The temperature range at which plastic equipment can be used is from -30 to +65 degrees.

It is important to note the main advantages and characteristics of the products:

  • specifications, installation + Photo and Video Due to the tightness of the septic tank, it can be installed even near the house and at the same time without the risk that an unpleasant odor is formed around the structure.
  • The transportation and installation of plastic products does not require the use of specialized equipment.
  • The plastic tank has a long service life, which is approximately 50 years.
  • The products are relatively inexpensive.
  • To use a septic tank, you do not need to provide the device with electrical energy.

In addition to the advantages that have already been listed, we note some disadvantages of the devices. Due to the relatively low weight, there is still a risk that during floods in the spring, groundwater will begin to push light plastic to the ground. But this situation can be easily prevented if you secure the structure during installation, and this implies an additional front of work during the arrangement.


Plastic septic tanks for sewage are containers that have divisions inside in the form of several partitions that form several storage compartments.

  • Wastewater and sewage from a residential building first enter the first chamber, while they drain freely and solid inclusions begin to settle to the bottom.

    Due to fatty deposits, a film forms on the surface of the liquid, and gradually it develops into a crust.

  • The second compartment in the septic tank was designed to cleanse the water anaerobically.
  • The third chamber has a removable filter, which also serves for cleaning.
  • But the last compartment often plays the role of a pump-type well with drainage, through which the liquid passes the last stage of filtration and goes into the soil.

In certain models in the first compartment, special preparations can be additionally used, which will also clear the liquid from worms.

In the basic configuration, it is assumed that there are nozzles made of polypropylene for the arrangement, which allow the waters to be purified naturally. Septic tanks can be of several types - polypropylene, polyethylene and fiberglass.

Installation rules

For the installation work of a plastic septic tank, the use of heavy equipment is not required. After the project for the future construction is created, you can begin to install the tank. Design work must necessarily be performed in accordance with SNiP and SanPiN, which have established certain requirements for the placement of the septic tank, namely, the distance of the device from the house.

Please note, that an important nuance that should be taken into account when creating a project is the minimum number of pipe turns. With a competent pipe laying scheme, you can reduce the cost of purchasing material, as well as facilitate installation work.

The work should be performed according to the following scheme:

  • The foundation pit should be larger in size than the containers that are inside.
  • To prevent the septic tank from floating up, it is sometimes possible to use a concrete sarcophagus.
  • After that, fasten the anchor belts, for this you can use nylon products with a tightening mechanism.

  • When the concrete has hardened, a sand cushion can be placed at the bottom of the excavation.
  • When the preparatory work is completed, you should start laying the pipeline, and the best option would be to use corrugated polyethylene pipes.
  • The final will be the installation of the structure, in which the tank will be placed in the pit at a depth of 150 cm.

When burying the container, gradually add water to it so that the walls do not deform due to for the external pressure of the earth layer.

  • If the design requires the installation of a compressor, take care of laying the electrical cable.

  • Based on the characteristics of the climate in which the septic tank will be used, additional insulation can be performed.
