A septic tank without pumping for a dacha. Septic tanks for sewerage

Many owners of suburban areas think about the question of how to create a septic tank without pumping out for a holiday with their own hands. It is necessary to recognize that such a system acts as the most inexpensive, and it can be used constantly.

Preparatory work

Initially, it is necessary to engage in excavation, which requires the excavation of the pit, because the construction will be underground. The volume of the excavation will depend on several factors, among which we can distinguish the daily water consumption for the family, as well as the intensity of use. If the average family lives in the house, then the water flow will be approximately equal to 1.5 m ³ , while the capacity of the purification system should be equivalent to 8 m ³ . You can use a more impressive volume, but if you properly organize the system, then the above will be enough.

The device of the septic tank assumes the preparation of a pit, which is made in the form of a parallelepiped with a facet length of 2 m. It should be noted that it will be difficult to carry out such works without the use of equipment, which in particular refers to the territory on which heavy soil is. But if you want to save, you can do with a shovel. You can dig a foundation pit in a day or two. It is not necessary to hurry, because the walls need to be given a flat surface, which is why you need to do the work carefully. On how equal the walls of the excavation are, the evenness of the filling of the mortar and the uniform strength depend.

Nuances of bookmarking septic

Installation of the septic tank should be carried out depending on the location of the freezing line. This is especially true in the regions of the central Russia. Pipes in such areas should be laid below the freezing line, if you do not want to go deep enough, then it is desirable to use a heater. Planning such procedures is necessary during the preparatory work.

Features of a monolithic septic tank

The septic tank, without pumping for dacha, works on the same principle as the traditional system, which has two wells in the structure. The structure without pumping has one pit, but after it is divided in half. Thus, each compartment acts as a cleaning stage. Despite the fact that such a treatment plant is economical, it meets all environmental standards.

Installation of formwork elements

Installation of a septic tank involves the installation of a formwork. But if you pursue the goal of making a low-budget design, it is recommended to use a sliding type of enclosing elements. This will eliminate the expenditure on a large number of formwork. In this case, the masters make shields exclusively for part of the system, and then move to the rest of the space. However, you will have to wait for the concrete to solidify in the first part of the system. Sliding formwork is also convenient because using such technology it is possible to easily compact the filled concrete.

In the role of the material for the enclosing elements, a chip or chipboard can be oriented. The material must be waterproof, and the price should not be worried - it is not high.

In addition to the above, you should prepare:

• Plastic pipe;
• Wooden bar, which will be needed to ensure the rigidity of the shields;
• Armature.

Installation of septic tanks at the dacha requires the presence of reinforcement, but if this could not be found, then it can be replaced by long steel items that have a circular cross-section. This can be, for example, a pipe diameter of 0.5 inches. Instead of reinforcing traditional rods in general, you can use any steel corners or rods, the main requirement, which is presented to them, is the bending strength. If necessary, to get a sealed septic tank, its bottom is poured with concrete at this stage and left for several days.

Technology of concrete bottoming

In the inner space of the pit, a formwork system should be installed, the elements of which must be fixed with each other according to the technology of wedging, using a wooden beam. At the same stage, it is necessary to equip the holes designed for water drainage. They need to be removed from each other by 30 cm and give a diameter corresponding to the pipe work that is supposed to be used for this. The pipes coming from the house, afterwards, must be put into the formwork.

Construction of a septic tank

By equipping the septic tank without pumping out for self-catering, the next step is to start the concrete work. To do this, initially it is necessary to close the mortar, which should contain Portland cement in an amount of 400 kg; Liquid plasticizer grade C-3 in a volume of 5 liters, 600 kg of sand and 200 liters of water. Before installing the mortar, it is necessary to install the reinforcement in the inner space of the formwork. This will ensure the strength and durability of the structure.

Making a septic tank without pumping for a dacha with your own hands, the concrete is initially poured into the first side of the pit, where the formwork is mounted. After that, you can leave everything until hardening, which will take about 2 days. But even after this the frozen solution must be checked for strength, only after it is possible to start dismantling the elements of the formwork. The next step will be the work on pouring the second part of the foundation pit.

Separation Separation Process

After you completely complete the work on the arrangement of the structural body, you can proceed to its division into separate parts, each of which will be equal in volume to another. This will ensure the following principle of the septic's operation. The first treatment stage will collect solid waste that is contained in the sewage, and also sludge. While the second will concentrate liquid waste that will have to overcome the filter, and then go down into the soil.

Septic tanks for cottages, the prices of which will be limited only by the cost of cement and sand, can be made from improvised materials. At the very beginning of construction, the task was to obtain the most cost-effective construction in terms of costs, and at the stage of erecting the separation wall, the same principle should be followed. This indicates the need to build a partition of existing building materials on the site. It can be stones, brick bricks, as well as concrete blocks. The main condition is the observance of the height of the hole through which the overflow will be made. According to the rules, it should be located 0.5 m lower relative to the entrance.

Before making a septic tank, it is necessary to prepare a pipe-tee, which is now actively used in the arrangement of sewerage wiring. With its application, water will come from below, which will help ensure that the heaviest particles do not overcome gravitational force and do not leave the first chamber of the treatment plant, which to a large extent will increase the efficiency of its operation.

Work on system shutdown

In order for the filled solution to become reliable and strong, and the septic tank is able to undergo the load of overlapping, it is necessary to wait a certain time, which is limited to approximately 14 days. During this time, concrete will significantly gain strength. There is a certain probability that during this period small cracks form in the walls, if such phenomena occur, then the errors must be eliminated by applying a traditional solution, which must be prepared in order to calculate the content of a third of the cement from the total amount of the mixture. Now you can proceed to shut off the septic tank, for this purpose, the channels are mounted, on which the overlap will rest, a board made of boards is covered with them. In this case, it is necessary to ensure the presence of lateral low sides, which will serve as a fencing hatch hole, located above the separation wall. In addition, it is possible to apply flat slate. On this we can assume that the septic tank for the house and the dacha is ready. It is quite convenient to use, but it costs very little.

Preparing before installing the septic tank "Topas"

Before proceeding to the construction of the septic tank "Tapas", it is necessary to choose a place for it, it must be removed from the house by 5 m or more. These rules are regulated by the SES. After you can prepare a foundation pit, the dimensions of which will depend on the model of the septic tank. If you prefer the "Topas 5" model, you will need to prepare a pit, considering the dimensions equal to 1000х1200х1400 mm. This indicates that the foundation ditch for it should have dimensions equivalent to 1800x1800x2400 mm. The next step is to prepare and install the formwork according to the principle described above.

The "Topas" septic tank assumes a sand cushion at the bottom of the pit, the thickness of which should be 15 cm. After the installation is finished, the septic tank will be 15 cm above the ground. This is necessary to make it more comfortable to operate the system during the snow melting season. In addition, this eliminates the possibility of damage to the structure.

Bookmark the station

It is important for the correct functioning of the system to make the correct choice of the station model. So, if underground waters are close to the surface of the earth, experts recommend choosing designs with the PR marking. In such systems, there is a forced drainage of sewage, which is done with the help of a built-in pump. Described septic tanks for sewage grades 5 and 8 are laid without the use of special equipment. With less impressive labor, the holes on the structural ribs will be able to handle the work, through them the rope must be passed and the system dropped into the pit.

Arrangement of the station

When installing the plant, it is necessary to use HDPE pipes Ø110 mm. They have to be cut into the septic tank at 70 cm from the top level of the soil. If in the work it is supposed to use the Long model, then this indicator will be slightly different - 120-140 cm. Besides this, it is important to observe also the slope of the pipes, which is affected by their diameter. So, if the material is Ø100 mm, then the slope should be 1-2 cm per 1 m; While for pipes Ø50 mm the slope level will be 3 cm.

Features of the connection process

The described septic tanks for sewerage after installation still have to be connected. It is necessary to observe the following rule. When the inlet pipe is positioned in relation to the ground surface at 70 cm, in a step from the foundation at 10 m, the outlet pipe should be located 50 cm from the surface.

Carrying out the sealing

In the outer shell of the system, it is necessary to make a hole for the pipe. Why it is convenient to use an adjustable crown Ø103-100 mm. A polypropylene cord can be found in the set of the station, which will allow soldering the branch pipe with the edge of the hole. For which it is recommended to use a construction hair dryer, which has a suitable attachment. As soon as the nozzle is firmly fixed, it can be strengthened with a pipe. The septic tank "Topas" must be leveled horizontally through the level.

In view of the fact that the system operates on electricity, the installation must be accompanied by a power supply. For what it is customary to use a PVS cable. It is recommended to take one that has a section of 3x1.5 mm. It must first be enclosed in a corrugated pipe, which is used for excavation, after the described preparation, the cable can be placed near the sewer pipe.

The plastic septic tank is connected by cable entry through the input, only afterwards it is possible to interface with the terminals. In the house, it must be connected to the switchboard using a separate automatic machine 6-16 A. As the final stage, adjusting the pressure when performing the dusting acts. This is required to compensate for pressure on the housing. It must be remembered that the stages of sprinkling and filling with water can not be separated. Thus, the system should be filled in 1/3, as well as fall asleep. The process should be repeated until the station is underground.

Septic tanks for cottages, prices for which can be equal to 85,000 rubles, can be installed independently, which saves.
