How to make a septic tank of their own hands of cubic - detailed instruction

«Facilities" in the courtyard of the 21st century - it is an anachronism.But, unfortunately, for one reason or another, not all owners of private buildings, even within the boundaries of settlements are able to connect their drains to a central sewage system.But for many owners of suburban real estate is even more problematic.

solved this question is quite simple - mounted standalone sewer system.Its "central" part of a septic tank - the construction, which is a collection of all waste in the area.The most expedient in practical terms, make it the cleaning (how to choose such here), as cumulative model requires periodic emptying, and it is connected with some difficulties.

First , will have to pay (calculated and the distance of the object) for coming and work assenizatorskaya machine.By the way, not so little, in the case of a country house.Call 1 "barrel" on average from 700 to 900 rubles (plus travel expenses).

Second , you must ensure that it is free entrance to the sleeve length.Hence, it is necessary to sacrifice some "economic considerations", because in this way does not make sense to equip the territory (to break the beds, planted shrubs).And when you consider that there are certain restrictions on the installation of septic tanks (they can not be placed anywhere), the problem of resettlement area is further complicated.

to be understood especially the installation of such "cleaner" because of cubic need to know what constitutes these products.In the classic version of a container of thick plastic which is placed in a metal frame enclosing the.Special pallet is provided for its safe implementation, which can also be plastic, wood or metal.Standard volume of one tank - 1000 l (although there are articles and 800 and 1050 liters).Weight - from 45 to 65 kg (depending on the material pallet and a wall thickness which lies in the range 1.5 - 2 mm).

meaning of article - to explain the method of installation of a septic tank, so to dwell on the calculations of necessary volumes and the number of products will not.We note only that for a family of 3 people enough to take two 1000-liter capacity.

Preparation excavation

Its dimensions are determined by the dimensions of septic tanks.It should take into account that capacity on all sides then will be warmed and concrete.Therefore, you need to dig a trench width of about half a meter longer (margin of 25 cm on each side).As for length, it is also considered necessary to connect overflow cubes, so they are somewhat spaced from each other (15 - 20 cm).Depth is recommended at least 0.5 m, but here you need to focus on the features of the climate, or rather by the amount of soil freezing.

Preparation

platform Consider one option - to drain into the soil.Features of the second method will only negotiate.Thus, the most common method of removing waste from the territory - into the ground, and this is done directly through the bottom of the 2nd cube.In this case, the 1st concreted platform on which it will be mounted.

For 2nd cube in the bottom of the pit is arranged a recess (about 35 - 40 cm).There asleep coarse sand and gravel fractions medium (thickness of the order of 25 - 30 cm).Thus, it turns out that the difference between the containers in height -. About 0.2 m

But if drainage will be installed aeration field, both cubes are placed on a common concrete base.

Preparation tanks

The 1st must enter the sewage pipe system.Between the cubes need to arrange overflow (also through the pipe section).If provided "territorial" drainage system (the field), then in the 2nd tank is another hole - drain.

The walls of containers holes cut out simply enough, by the diameter of the pipes used.As the cubes of plastic, and the need to use tubes of the same material.If use of metal, cast iron, the difference of thermal expansion coefficients lead to the formation of cracks and subsequent leakage.

Log in 1st container - at the top.overflow hole on the opposite wall - 15-20 cm below.

For compounds are used, including, and a variety of tees, reducers.It all depends on the characteristics of the track assembly, as it comes to containers, a drop height (if available).Any landlord realized that he needed.

In addition, each cube in the upper part, cut out holes for ventilation ducts, otherwise avoid gassed containers with all the consequences (for more details about the septic tank ventilation here).

should not forget about the drainage.Therefore, in the bottom of the 2nd container and around the bottom portion (at a height of about 15 cm) is drilled "mesh" of openings through which fluid will leave.

Some sites say that this is done through a hole under the vent stack (after it is removed).But the question arises - and what must be its diameter, to be able to qualitatively clean septic tank?

Installation cubes

explain nothing here, except for one.They should be fixed, to be able to produce a high quality finish insulation and subsequent concreting.This is done differently.Given that Cuba "dressed" in a metal frame to make it easy.For example, to weld them into a specially built-in concrete loops, hooks using strips, rods.

Connecting pipes (fittings)

must be carefully repaired all joints.To do this you will need a silicone sealant.Use the solution should not be, because this sealing lasts a long time.

external finish

as insulation, given the correct form of cubes, you can use foam (and sides and top).If you put mineral wool, how then concrete?And it needs to be done to prevent deformation of the containers due to seasonal ground displacements.

application layer of the solution on the entire surface of the septic tank.Depending on local conditions, it can be done and additional reinforcement plates on top of the foam.

All that remains - to fill the pit land and its good ram.

Useful tips

• Since during installation, an additional "strengthening" the cubes, it is advisable to buy used products / y.They are much cheaper - from 1 500 to 2 500 rubles / pcs.
• In determining the depth of placement of the septic tank is necessary to take into account the characteristics of routing sewage from the house.In order to ensure a reliable flow it should have a bias towards the containers about 1.5 cm per linear meter.
• If groundwater is quite "high", the autonomous system is mounted under option "drain field".
• To reduce the intensity of the formation at the bottom of the 2nd tank solids and thereby increase the period until the next cleaning it, it is advisable to fill in this cube special supplements.On sale they are.This will increase the degree of splitting of the solids and reduce siltation of the bottom of the septic tank.
