Installation of a septic tank of concrete rings with your own hands: scheme

To a country site was suitable for a full-fledged residence, it is necessary not only to conduct to it all appropriate communications (light and water). It is also necessary to install a septic tank, which will ensure a normal discharge of waste water.

Types of septic tanks on the site

There are several varieties of such structures that are used on the site:

• Simple drainage pit;
• Plastic septic tank with a certain number of chambers;
• Septic tank of concrete rings.

The last species is considered the most popular and simple in the construction.

Selecting a location for a septic tank on the site

It is worth noting: in order to perform a quality installation of a septic that will be used for a long time, it is necessary to choose the right place for it.

First, the sink pit should be kept as far as possible from the dwelling house and any outbuildings. This will save buildings from flooding. Secondly, there should not be plantations on a plot of several meters around the septic tank. Especially it refers to the garden.

Council. Installation of a septic tank should be done closer to the entrance to the yard, so that it is possible to clean it normally with the help of special equipment.

Plan of works for the installation of a septic tank in a suburban area

It should be noted that the installation of the septic tank is carried out in stages. First, you need to choose the right place for him. Secondly, draw a drawing of the future design.

Important. This stage is the most important, since on the basis of its data it is possible to calculate correctly the necessary amount of materials for the installation of sink wells.

Then you need to do the following:

• Excavate the excavation;
• Install concrete rings;
• Lay and connect all necessary pipes;
• Seal the joints of the material;
• Installation of floors;
• Pouring the septic tank.

This is a peculiar scheme of installing a septic tank, which allows all the works to be performed correctly and qualitatively. At the same time they use special equipment and improvised tools.

Note. You can easily perform the installation of the septic s yourself, for this you do not need to have special knowledge in this area. It will be sufficient simply to know the principle of the operation of such a construction.

Excavation excavation

Once the site for the installation of the sewage pit is chosen, it is possible to start digging out the pit. It is worth considering that the size and diameter of such a structure depends on the daily water consumption for each member of the family. In order to be able to live on a countryside site, it is enough to make a hole up to 3 m deep. At the same time, its width (or diameter) will be:

• 70 cm;
• 80 cm;
• 90 cm and so on.

This parameter is based on the diameter of the selected concrete rings.

If the pit is digging by hand, then you will need:

• A manual drill or a simple drilling rig;
• shovel;
• bucket.

Initially, along the perimeter of the future septic tank, with the help of a shovel and another garden tool, all vegetation is removed from the soil surface, a depression is dug in 20-30 cm. Then the drill is set and starts to work to a depth of 50 cm. Then dig a pit of the necessary depth and diameter with a shovel. Excess ground is raised to the surface with a bucket. It is also necessary to use a ladder for easier descent and ascent.

If the septic is excavated with the help of equipment, then a minimum amount of a tool is required: a shovel. Specialized machine bucket will make the necessary deepening.

Important. Dig carefully. Especially if a person does not know at what level there are groundwaters. They should be as far from the septic tank as possible so that the contaminated run-off does not clog them.

There is one recommendation for the construction of a sewage well: do not continue the digger if water has already appeared on the bottom of the pit. This design is best to fall asleep and not use in the future.

Installation of concrete rings

Since such products have a large mass, they must be installed only with a special tripod, which is built independently, or a crane.

Council. It is better to install the septic tank from concrete rings with special equipment. This will greatly facilitate the work and reduce the time and effort spent.

The first ring is mounted on a special substrate. It is made of sand, gravel and gravel. This is a kind of natural filter that can detain harmful substances in the pit. It is necessary to ensure that the ring after installation is in a flat plane. For this reason, further installation will be simple and fast.

The second ring is mounted on the first, and so on. Thus, an even structure is obtained, which requires additional finishing.

Piping

Originally from the house there are pipes. They are laid at a depth below the freezing level of the soil. Otherwise, it is necessary to insulate them with the help of special materials or to apply the technology of milling. It has been used for a long time and is a "pipe in a pipe" construction, that is, the waste pipe is insulated with mineral wool and inserted into a pipe with a large diameter. Because of this, the entire structure will not only be insulated, but also protected from exposure to moisture and pressure of the soil.

Lead the pipes almost to the center of the septic tank. In some cases, they can be placed below. Only it is worth considering that quite often due to the receipt of a large number of sewage pipes are clogged and cleaned by themselves will not be possible.

Sealing of the structure

First, the rings installed in the septic tank must be fastened together. To do this, use a concrete solution made with the use of sand, concrete and water and with the addition of special substances to give such a means of moisture resistance and strength. It is applied to the joints and slits of the material.

Secondly, the outer diameter of the septic tank should be covered with a roofing material or other material to protect it from flooding with rain or melt water.

Then they proceed to the upgrading of the structure and install slabs on the surface of the ground, which are the basis for mounting the septic lid.

Bedding of a sewage pit

Installation of the septic tank from the rings can be considered complete only if all the work on the installation of the material and the protection of the entire structure will be carried out.

The final stage will be the implementation of the undercoat around the septic tank to a depth of 50 cm. Use gravel or crushed stone for small fractions. They are covered by the outer diameter of the structure and covered with a layer of peeled sand from above. You can pour concrete solution.

Once all the work is done, you can use the septic tank.
