  • septic tanks-septic tanks, in which an additional soil cleanup, in fact are multi-chamber structures. All the cameras buried in the ground and connected with each other playing walls or pipes. The latter capacity will not be sealed. In each tank the water settles, and the last goes to the ground in a more or less free from contamination;
  • sewage treatment plants can produce a very deep cleaning of wastewater. They are usually installed in areas where it is forbidden to dump into the environment of poorly treated water.

The device is homemade septic tank

The scheme of installation of a septic tank for a private home requires a completely correct definition of the installation site. It necessarily takes into account the location of water underground.

A useful tip! The septic tank must dig in “downstream” than the house itself, and outbuildings to the well. In accordance with accepted sanitary standards, it is not allowed to be put closer than 15 m from any open water, from water well and not closer than 50 m Distance between septic tank and the neighbour’s fence is defined more than 2 meters.

The order of execution of works

With the installation of the treatment plant is required to perform a specific procedure:

  • First, for the above rules determine the location for the installation of a septic tank.
  • In the second phase, dig pit of required size.
  • Prepare the formwork.
  • Carry out concrete solution (or constructed septic tank of concrete rings).
  • Produce internal partitions.
  • Installed on the septic tank cover.
  • Consider all this in stages.

    Step 1: site selection and preparation of pits, supply of sewer pipes

    Works with ground

    Excavation is the initial stage of the construction of any septic tank. If organized and designed everything right, then its volume can be very minimal. Most importantly, there is adequate space around the walls for ease of installation capacity. Optimal for a private home is the volume formed vosmikova pit 2х2х2 m. a Slight increase will not impair the effectiveness if there is the possibility of hiring earth moving equipment.

    Step 2: reinforcement

    Placing formwork

    After the desired depth of the hole was completely dug out, you need to install the formwork, which becomes necessary in the presence of a certain number of sheets of osb, lumber, scraps and sewage pipe made of PVC. In the mold you want to make holes that will provide excellent water drainage into the ground. That’s what is required and the plastic pieces of pipe.

    Sheets of osb make round holes at a distance from each other in 30 cm as osb — too flexible material having low rigidity, it is necessary to strengthen a bit. In order around the perimeter of the sheet attached to the bars 20×30 or 30x40mm using conventional screws. Vertical ribs are fixed every 50 cm. of Such sheets will need to do at least half of the pit.

    Step 3: installation of the formwork

    In order to prepared formwork has not collapsed under the heavy concrete and mortar, need some lumber riving her right in the pit. Plastic liner from a piece of pipe inserted into the prepared holes so that they land zaglublenie approximately 5 cm Otherwise the concrete can squeeze and spill out through the holes.

    A useful tip! Formwork is better and cheaper to make collapsible, so that the shields can be moved from wall to wall. To play everything have separately, as adjacent wall, and the wall should be divided into two independent parts.

    Step 4: concreting

    Concrete tanks septic tank

    When preliminary preparations for the construction with his own hands of a septic tank for a private home is completed, you can begin adding the concrete mix. It is better to rent or buy a cement mixer. For the preparation of liquid concrete will require:

    • the sand is fine (2 parts);
    • fine clastic gravel (2 parts);
    • cement in bags (1 part).

    Step 5: installation of metal parts

    All this must add water and mix thoroughly. Among other things and will need reinforcement. Through these rods, the cement becomes a solid reinforced concrete. If there are no bars, you can use any other available metal, but not the pipe. After the first half of the pit is flooded, you need to wait about 2 days until the entire mixture is dry. Then rearranging the formwork on the other two sides and repeat the whole procedure again.

    Step 6: laying flat slate, fixing vent pipe

    The construction of baffles in the tank

    After the construction of the walls begin to split the total volume of the septic tank into two parts. It is important that in the first compartment of the holes in the walls should not be, they all have to be in the second container. This point needs to be taken into account at the stage of mounting boards for formwork.

    The wall can be poured concrete or brick to do. She needs to share all the pit into two about the same pit. The first will be to settle the sludge and particulate impurities, which can very quickly clog the pores in the soil. The other part of the container is filled relative to liquid water, which enters through the top of the wall and goes through the holes into the soil where it is filtered.

    Step 7: design of manholes for maintenance of the septic tank

    A useful tip! It is very important that the height of the overflow through the wall was correct. Namely, it needs to be 40 cm below the level of the pipe coming out of the house. Here there is a minimal amount of silt.

    How to increase the current efficiency and the standard lifetime of a septic tank

    When will be installed DIY septic tank for a private home, it is not necessary to start its operation immediately. To the bottom of the second division did not silt up quickly, there with sharpened pieces of pipe called jelonki, punch the holes to a depth of 2 m. They can also drill to drill. Openings closed mesh, which is then poured gravel. The drainage is very good drains water and prevents the blurring of soil, which significantly increases the service life of the septic tank.

    Step 8: concrete septic tank with cement mortar

    An important factor influencing the overall health of the septic tank, is the presence of ventilation. Make it not difficult. After all, it is sufficient to use the sewer pipe, which is simply displayed on the surface. Close the septic tank top can be anything: sheet iron, concrete slab, or you can pour concrete yourself.

    This makes a beam from the channel, which laid the planks treated with tar. Leave a small hatch to sometimes scrape solid waste. The rest of the area, previously covered with tar paper, fill with concrete, not forgetting to arrange the reinforcement.

    Step 9: the arrangement of audit of the mine

    The basic rules for using homemade septic tank

    • can not be discharged into or in the sewer debris;
