Is it possible to use the eurocube under a septic tank. How to make a septic tank from eurocubes with your own hands: step-by-step assembly instructions

03.03.2020

A Eurocube septic tank is a hermetic structure for cleaning used dirty water. It is installed in household plots where there is no centralized sewage system. It's more convenient and efficient cesspool. Recently, many are interested in the device and the principle of its operation.

Why is a septic tank from eurocubes popular

Human life is associated with the observance of hygiene rules: washing clothes, washing dishes and food, cleaning rooms, bathing, visiting the restroom. This necessary activity leads to the formation of effluents. A septic tank from eurocubes helps to equip the conditions at the modern level. It has a number of advantages:

Made from thick plastic.
It has a simple and compact design.
Prevents the appearance of unpleasant odors.
Filters waste water.

What is eurocube

This is a container with rectangular edges made of white, blue or black plastic. Each has openings that are used in the system to draw in and drain liquids. The eurocube under the septic tank is buried in the ground, where it is subjected to pressure, but the plastic with reinforcement does not lose its tightness during prolonged operation. Its strength is enhanced by rigid ribs and metal frame which improves product reliability.

The walls of the cube are able to withstand the load and not deform, even if sewage is supplied under pressure. The material of the cube does not interact with aggressive substances and does not change its properties due to changes in temperature and humidity. Cracks do not appear in the body under mechanical stress. You don't have to worry about harmful effluents getting into the environment.

The main parts of the eurocube:

1) Plastic walls.
2) Filling pipe with a cap, its diameter is 150 mm.
3) The vent valve, it is next to the filler neck.
4) Drain cock located at the bottom.
5) A metal crate that encloses a plastic container (flask).
6) Pallet made of metal or wood.

The principle of operation of a septic tank from Eurocubes and the stages of filtration

After cleaning, the contaminated liquid becomes safe for release into the environment, as it first passes through several stages of filtration:

Drains enter the first chamber, where large debris is screened out.
After rough cleaning, sewage enters the chamber with biological products. Here, organic matter is processed by microorganisms.
The liquid enters the filtration field for finer cleaning.
Purified water is thrown into the soil on the plot.

The filtration field for thorough cleaning can be omitted. After passing the main stages, stocks lose bad smell and become safe for nature.

Important Calculations

It is easy to build a septic tank from a Eurocube in the country with your own hands. Before starting work, preliminary calculations and preparatory work are necessary.

Official consumption standards cold water per day per person: 200 liters of cold and 100 liters of hot. Multiply the standard by the number of people in the family and by 3 days required for settling and cleaning. Divide the resulting volume by the volume of one cube and round up to a whole number. The table shows the standards and calculation results for cubes with a volume of 1 m3.

It is cheaper and easier to get a septic tank from one Eurocube, but when calculating it is better to take into account not only personal needs, but also the possibility of visiting guests. Calculate the volume for a septic tank with a margin. Add another cube for incremental filtering.

Actual water consumption usually does not meet the standards, so take into account your individual needs when calculating. Use water meters for calculations.

Design

You can not arbitrarily build a septic tank even on your own site. It must comply with sanitary and building codes. The distances from the designed treatment plant to the nearest objects of the site are taken into account:

A source drinking water, well - 50 m.
Medium-sized fruit trees ─ 3 m.
Shrubs ─ 1 m.
Reservoir, lake ─ 30 m.
Road with active traffic ─ 5 m.
Streams and rivers ─ 10 m.
House ─ 4-5 m.
Outbuildings─ 1m.
Neighbor's plot ─ 3 m.
Gas pipeline 5 m.

When designing, the composition of the soil, its filtering ability, the depth of freezing, and the features of the relief are taken into account. On sloping terrain, the septic tank is located below the drinking well.

In order for the supply pipeline to function successfully, an artificial slope is created, and revision wells are made at the corners. There is also a free access for sewers, who will periodically inspect and clean the septic tank from silt.

Marking, earthworks and foundation

You can learn the technology of how to make a septic tank from eurocubes with your own hands, then follow the workflows, but first you have to perform a few simple and important activities.

Specify the location of the boundary and the coordinates of your personal plot, and then proceed to the internal layout of the future object. Transfer the main points from the project to nature, mark them on the site with pegs and stretch a string between them.

Now, in the area marked with pegs and twine, dig a pit. The levels for the compartments are made different so that the liquid flows freely from one cube to another. Make the perimeter of the pit wider than each cube by 0.3 m, and the depth of the trench more height cube by 0.5 m without taking into account the upper embankment. If possible, the first tank is placed below the freezing depth of the soil.

Add sand to the bottom of the pit, then gravel and tamp. The height of each bedding is approximately 30 cm. Install a removable formwork from boards and pour concrete 0.2 m high. Cover the surface with polyethylene and wait for complete drying. The drying period depends on the environmental conditions, its duration is approximately 1 month.

Soft soil under the weight of full flasks can sag, then the tightness will be broken at the joints. Do the backfilling, tamping and concrete pad more carefully.

Connecting eurocubes to the system

For installation you will need: sealant, liquid waterproofing, insulation, steel elements, tees and plastic pipes(d= 150 mm). Start with the first cube, make a hole in it with a grinder at a distance of 0.2 m from the top and connect it to the sewer pipe. Then, on the opposite side, measure 0.3 m from the top surface for the second hole. Connect the first and second cubes.

On the second and subsequent flasks, also make two holes at a lower distance from the top edge. Connect a pipe to the outer cube to drain to the filtration field (well). Leave holes on top of each tank for ventilation pipes and periodic cleaning. Insert a control pipe into the neck of the first cube. Secure it with a rubber sleeve and hot glue.

Cubes are placed at a distance of 20 centimeters, connect metal parts or weld. You should get a single rigid structure. Treat the joints of pipes with walls with silicone sealant and liquid waterproofing.

Insulate the outer surface of the cubes and the pipeline with mineral wool or foam plastic. Connect the sections of the system so that the liquid overflows freely. Fill the system with water to check the tightness and prevent soil pressure on the walls during backfilling.

Is it possible to make a septic tank from one eurocube? The system must have at least two chambers that perform settling functions. You can divide one container with an internal partition.

backfilling

The system must be covered with earth. Masters offer several options for finishing work:

Prepare a mixture of sand and dry cement 5: 1, then pour it in layers into the sinuses between the walls of the pit and cubes. Water each layer.
Pour liquid concrete, using the crate of eurocubes as reinforcement.
Insert sheets of corrugated board or slate around the cube around the perimeter of the pit.
Connect the reinforcement of the concrete pad to the frame of the system.

Choose the method that will be optimal in terms of price and features of the soil and climate. From above, cover the system with foam insulation and penoizol, backfill and level the soil.

bacteria

Waste creates an environment for decay and bad smell. Add bacteria to the second chamber to speed up the breakdown of wastewater into simple substances (gas, water, nitrates). The use of anaerobic bacteria together with aerobic bacteria is effective.

Under their action, solid waste first breaks down, then it is converted into fertilizers. With microorganisms, the septic tank works more efficiently, cleaning is less often required, there is no smell. Stores sell formulations suitable for the processing of contaminants that differ in composition and conditions.

Perfect cleaning

You can improve the purification of water after it passes through the septic tank. Dig a filtration well, and fill its bottom with sand and gravel. So the water will undergo natural purification and gradually seep into the soil. Or make a filtration field, it resembles an irrigation system. Effluent will circulate through pipes with holes, gradually seeping through and at the same time irrigating the soil.

For the device of the field, use a central pipe with a diameter of 150 mm or more, lay it at a slope of 2 cm per 1 linear meter. Irrigation pipes up to 20 m long and 100 mm in diameter. At the end of each water pipe, make a riser for ventilation.

Constructive decisions

Use plastic containers for reinforcement existing system or together with concrete rings. You can make a septic tank with your own hands from one Eurocube, but according to the device, it will resemble an ordinary cesspool for a village restroom. Plastic reliably protects the soil from impurities, but the flask will have to be cleaned regularly. If you cut off the bottom of the eurocube and put it on a pillow of sand, gravel and geotextile, you get a pit with filter layers.

The Eurocube is universal, it is convenient for various household needs: rainwater collection, a small pool, a shower, food storage, a greenhouse and aquaponics, a cesspool and a septic tank.

One of the simplest and most affordable options for a treatment plant for a house or a summer residence is a septic tank from eurocubes. In combination with good drainage it will effectively clean drains and work smoothly for many years. Let's look at how to make a septic tank with your own hands from Eurocubes, in detail with calculations and step-by-step instructions.

For those who are faced with the problem of choosing a treatment plant, the question often arises: is it worth spending money on a septic tank when you can get by with an ordinary cesspool. It is possible, but it may not withstand large volumes of water from all sanitary facilities, and the aromas hovering around it are not always acceptable in a private area, especially in a small one. In addition, untreated domestic sewage can contaminate The groundwater, then you can feel their smell or even a slight taste at the nearest well, and this will not please the workers of the sanitary and epidemiological station.

With a septic tank, these problems can be avoided, but since the cost of industrial facilities is quite high, homeowners have to look for an alternative. And the most acceptable option in terms of cost and ease of installation was a Eurocube septic tank.

Construction and

A Eurocube septic tank is a single hermetic system that consists of one or more tanks. The sewer is connected to the first tank, and the effluents enter the tank, where they are rough cleaned.

The principle of operation of a septic tank from eurocubes

Sewage is settled and divided into several fractions with different specific gravity, namely, sediment, gases and clarified water, which is in the middle layers. Also, water purification is facilitated by microorganisms that feed on organic waste. To maintain them in the required quantity, special mixtures of bacteria for septic tanks and cesspools are added to the container. Through the overflow pipe, water from the first tank passes into the second, where it also settles and ferments.

The effluent clarified in the second tank is approximately 60% free of impurities. Next, the water goes to drainage system where the soil treatment takes place. As a result of fermentation, a certain amount of methane, carbon dioxide and hydrogen sulfide is released in the first and second chambers, they are removed through ventilation pipe. Fluid is being pumped out cesspool machine through the cleaning pipe.

The main element of the treatment plant is the eurocube

Eurocube is a plastic container made of high-density polyethylene, its wall thickness varies between 1.5-2 mm. In the upper part of the cube there is a filler neck with a diameter of 150 mm, a polyethylene cap is installed on it, in addition it can be equipped with a ventilation valve. A drain cock is located at the bottom of the tank.

The principle of operation of a septic tank from eurocubes

Each eurocube is enclosed in a metal crate and installed on a wooden, steel or plastic pallet. Like many other plastic containers, eurocubes have their own sizes, so the question: which one to buy rarely arises. The standard container is 1000 liters, its length is 1.2 m, width is 1 m, height is 1.16 m, weight is about 50 kg. The Eurocube is an almost ready-made tank and requires only minimal installation work, which is why sewerage with a septic tank made of polyethylene tanks is becoming more and more popular.

Norms and rules for the location of a septic tank on the site

The basic requirements for a septic tank are drawn up in construction, sanitary standards and rules, these are the main documents that determine the design of the treatment plant, taking into account the adjacent buildings and the characteristics of the territory. Before installing treatment facilities in a private house or country house, it is necessary to prepare and approve the project in the relevant organization.

During the construction of septic tanks, it is important to pay attention to some features of its installation in certain conditions.

Norms and rules for the location of a septic tank

The installation depth of the septic tank, no matter what design it will be, should not be less than the soil freezing limit, if the requirement is not feasible, the septic tank must be insulated.
The soil must have high permeability, sandy and
gravel soils. In the case of clay soil, the construction of cesspools and the installation of a pump will be required.
If there is not enough territory on a private plot
for ground filtration, the construction of an aeration well will be required.
When placing a septic tank on the site, it is worth considering that, like for cesspools, it will need to be pumped out and you need to take care of the possibility
equipment entrance.

Calculation of the capacity of the septic tank

In order for the sewerage system to be functional, and the installation of a new septic tank in a private house is not in vain, it is necessary to calculate in advance the estimated volume of drains, and, accordingly, the volume and number of containers.

According to SNiP 2.04.03-85 “Sewerage. External networks and structures” per person, the volume of water consumed is about 150-200 liters per day.

The standard rate of water consumption per person per day is 200 liters, even if, in fact, they take this number into account less and multiply it by the number of people living in the house. The resulting figure is multiplied by 3. 3 days is the standard time for which the water in the septic tank is cleared and partially drained. Now, to determine the volume of the tank in m3, the resulting amount is divided by 1000. Thus, for a family of 3 people, the volume of the septic tank should be 1.8-2 m3, that is, 2 eurocubes will be needed. If there are guests in the house, it is recommended to add 200 liters to the total capacity.

Stages of installation of a septic tank from eurocubes

Sewerage with a septic tank from eurocubes differs from other treatment facilities in that additional arrangement will be required

Drainage and drain system

s, but with correct installation such a design will be a reliable and durable solution in a private house or in the country.

Before proceeding to installation work, think over the design and location of the septic tank on the site, decide which one is better to install so that the sewerage in a private house is functional and coordinate the plan in the SES.

Preparing a pit for a septic tank.

The length and width of the pit should correspond to the size of the septic tank assembly with a small margin of 15-20 cm around the entire perimeter. Thermal insulation and durable material that protects the septic tank from squeezing will fit into this gap.

The required depth is determined taking into account the size of the Eurocube and the slope of the common pipeline. They also take into account the height of the concrete base under the septic tank and the moment that each next container is installed 20-30 cm lower than the previous one, respectively, and the bottom screed is made with a step, and fastening loops for the eurocube are installed in the fresh solution.

Earthworks and concreting of the base for a septic tank

Anchoring will protect the structure from displacement in the event of a breakthrough ground water.

An important point: so that the septic tank does not squeeze out in the spring with groundwater, it must be fixed to concrete base belts.

The next stage of earthworks will be digging cesspool trenches for filtration field or a well. Work may vary depending on the chosen method of soil post-treatment.

Septic tank drainage system

Soil treatment can be organized in several ways.

Filtration wells - a simple and inexpensive construction, is a well, the bottom of which is made in the form of a filtration cushion of sand and gravel. But it is forbidden to install it on many types of soil: sandy loam, sand, fractured soils and loams. The productivity of the wells is small, and the installation must be coordinated with the sanitary and epidemic service.
Underground or ground filtration fields are a kind of irrigation system through which wastewater processed by a septic tank passes and enters the soil. Arrange a system of ceramic or plastic perforated pipes laid on the filtrate. At the end of each channel, a ventilation riser is brought to a height of up to 0.5 m.

Filtration systems for a septic tank

Filtration trenches are pits up to 1 meter deep, in which pipes more than 30 meters long are laid, through which water flows by gravity into the existing network or storm sewer.

Assembly and installation of a septic tank

The septic tank is assembled according to a pre-designed scheme, adhering to the basic rule - all connections must be absolutely tight, builders have no consensus on which sealant is best to use.

The assembly begins with the preparation of the first container. From the upper edge of the eurocube, 20 cm recede down and make a hole for the branch pipe, which will connect the treatment plant with outdoor system sewerage. On the opposite side of the cube, at a distance of 30 cm from the top, a second overflow hole is made, through which the drains will pass into the second container.

Several holes are also made on the second Eurocube. The first is cut out for an overflow pipe that will connect the tank to the first tank. The height of the slot is calculated taking into account that the second tank will be located 20 cm below the first. On its opposite side, 15-20 cm lower, a hole is made for the second overflow pipe, it will divert pre-treated effluents to the filtration field.

On top of each tank, it is necessary to organize a hole for cleaning and ventilation duct. As a rule, only one hole is made from above, and a pipe is fixed in it for cleaning, and the ventilation riser is brought out using a ready-made filler hole. The pipe is selected with the appropriate diameter and raised to a height of up to 2 meters. Be sure to take into account the fact that the ventilation pipe should not be lowered into the tank below the overflow pipe.

Assembly and installation of a septic tank from eurocubes

Advice! If the ventilation riser is made collapsible, then in the future, liquid can be pumped out of the septic tank through it and an additional hole and pipe outlet for cleaning will not be required

Septic tanks are connected to each other with steel elements at a distance of 15-20 cm. The structure can be insulated with mineral, basalt wool or foam, do not forget about the insulation of pipes that are located above the freezing level of the soil.

Rest in country house, away from a noisy and dusty city, it's good when all the appropriate conditions are created for this. V modern world it is impossible to do without the arrangement of water and sewer systems.

Some inhabitants of dachas and private buildings, due to the lack of nearby centralized engineering and technical communication networks, find a way out in the construction for the sewer needs of ordinary drain pits. It will not cost too much, but there are many problems in the process of further operation.

Many of these problems can be avoided by building a septic tank using eurocubes. It is not difficult, and the service life of such a sewer structure is quite long.

Why eurocube?

A Eurocube is a polyethylene container with a wall thickness of about two millimeters. From above, the cube is equipped with a filler neck (diameter 15 centimeters), closed plastic lid with valve for ventilation. At the bottom make a tap for draining.

What is the benefit of using this type of septic tank:

Its installation requires a minimum of costs, since the eurocube is a ready-made tank.
The spread of unpleasant odors is excluded.
The soil is not infected from the decomposition of human waste.
There is no need to often use the services of a sewer, since such a septic tank is not cleaned very often, and besides, it is easy to do it yourself.
The service life is much longer than that of a cesspool.
Service time for this sewer device practically not required, so it cannot break from.

The principle of operation of a septic tank from eurocubes

Such a septic tank is a single geometric system, which usually includes several containers, although for a small building with a small number of residents and seasonal use, one is enough.

Through the sewer drain pipe leaving the house, dirty water with waste enters the first tank. There it is subjected to rough purification, stratification of sewage, dividing them into fractions with different specific gravity.

Waste water is purified by special microorganisms that use organic waste for nutrition.

In order to have enough of them, a special bacterial mixture is used, which is added to the septic tank.

Through the overflow pipe, the liquid moves to another container, continuing to settle and ferment.

The clarified sewage, cleared of impurities by 60 percent, then flows into the drainage, where it is further cleaned with soil.

How to make a septic tank yourself from eurocubes

When constructing a septic tank, one should be guided by construction, as well as sanitary norms and rules, in order to competently take into account the adjacent buildings and the features of the adjacent territories.

The following are points to consider during installation:

The septic tank should be installed at a depth below the freezing level of the soil. If this is not possible, it must be insulated.
The soil around the septic tank must have high permeability. Well suited sandy and gravel soil. If clay inclusions predominate, it is necessary to build a cesspool and install a pump.
If the soil has poor filtration, an aeration well is built.
The septic tank should be located so that it has access to pumping equipment.

Capacity calculation

Prior to the start of all work, it is necessary to calculate the magnitude of the expected effluents in order to select the appropriate number of containers.

The SNiPs regulating the construction of sewer facilities indicate that one person consumes from 150 to 200 liters per day. This figure is multiplied by the number of family members, then by 3. It is for a three-day period that the water purification cycle in the septic tank is calculated.

Installation of a septic tank

First, they dig a pit corresponding to the size of the eurocubes, making a margin of about 20 centimeters along the entire perimeter where it will be laid thermal insulation material. You can also install something strong here to counteract the squeezing force.

The depth is made based on the height of the tank and the main slope. The installation of each subsequent eurocube is carried out below the previous one by 25 - 30 centimeters. The height of the concrete cushion under each container is also taken into account.

drainage system

Soil post-treatment of water can be arranged in different ways.

First way. Construction of filtration wells. This is done simply and inexpensively. The bottom of the dug well is made as a filtration sand or gravel cushion. This method is not suitable for soil such as sand, sandy loam, loam. Such an installation must be coordinated with the SES, it is difficult to achieve high performance from it.
The second way. Construction of fields that carry out underground and ground filtration. This is a kind of irrigation system that passes wastewater processed by a septic tank before it goes into the soil. For the system, perforated ceramic or plastic pipes are used, which are laid on the filtrate. Ventilation risers about half a meter high are brought to the ends of the channels.
The third way. The construction of filtration trenches, that is, meter pits up to thirty meters long, where pipes are laid. Drainage water flows by gravity into the storm drain.

Assembly, installation of a septic tank

The assembly of the septic tank is done focusing on a pre-designed scheme. Each connection must be carefully sealed.

On the first Eurocube, twenty centimeters below the upper limit, a round entrance is made, into which a pipe is stuck, connecting the container with an external sewage system. A round exit is made from the opposite end ten centimeters below the entrance, for pouring drains into the next Eurocube.

At the second eurocube, an entrance is made from the first, not forgetting about the difference in tank levels. From the other end of the cube do round exit, where the second overflow pipe is inserted to divert treated effluents to the filtration fields.

The upper surfaces of the tanks are equipped with openings for ventilation and cleaning. It is possible to perform both functions through one channel. The ventilation pipe is made two meters. Its lower edge is located above the level of the overflow pipe.

Eurocubes are connected with steel elements at a twenty-centimeter distance. For insulation, mineral wool, polystyrene are used.

Norms and rules for installing a septic tank on the site

A septic tank can create serious problems with errors during its installation, if untreated drains end up in ground aquifers.

When installing a septic tank, SNiP standards should be strictly followed:

It is more expedient to use small hills to install a septic tank, in order to avoid flooding and overflow of eurocubes with melt and rainwater.
It is necessary to take into account the level of groundwater in the area in order to minimize the risk of flooding and floating of tanks during floods.

It is necessary to adhere to certain standards for distances on the territory of the site:

the septic tank is installed further than a five-meter boundary from the main building,
to the nearest standing reservoir - a thirty-meter zone,
to the riverbed - ten meters,
to the drinking well - fifty meters.

Septic tank maintenance

For effective uninterrupted operation of the sewer, it is necessary to ensure that the containers do not overflow, and also to carry out the following measures:

If it is necessary to pump out liquid from containers for prevention, do this in the autumn, when microorganisms are less biologically active. This reduces the causticity of the unpleasant odor.
When cleaning containers, do not forget to leave a little silty substance in them to accelerate the further activation of bacteria.
The entrance to the septic tank must not be littered so that it is possible to use the sewer machine.
When using the sewer system in your home, do not throw anything down the toilet that could clog the pipes in the sewage system.

Do-it-yourself septic tank from eurocubes

It is good to relax in a country house, away from a noisy and dusty city, when all the appropriate conditions are created for this.

Eurocube is a durable plastic container for sealed and reliable transportation or storage of liquids. It is equipped with a mesh-shirt made of galvanized steel, resistant to stress. Most of the autonomous waste treatment plants have the form of several tanks designed for settling processes. Owners country houses we offer information on how to make a septic tank with your own hands from eurocubes.

The advantage of using eurocubes for receiving sewerage

Private households most often have to independently deal with the treatment and disposal of domestic wastewater. The article will answer your question of how to inexpensively, effectively build a septic tank for your home and create a modern, environmentally friendly, efficient option instead of a classic cesspool.

A septic tank is a well designed to receive and treat wastewater. Until recently, concrete rings served as a popular material for manufacturing. This option does not satisfy many owners for a number of objective reasons:

building cost,
low environmental friendliness,
service complexity.

Installation of modern treatment systems, for example, Topaz, is also not a cheap pleasure. A septic tank made of eurocubes, which has efficient performance and is easy to maintain, will serve as a budget option for each option. For the construction of a modern cesspool, used containers are suitable, the cost of such containers is 2-3 orders of magnitude lower than new products, and a large volume of 800 to 1000 liters is ideal for the planned construction.

Calculation of the capacity of the septic tank

It is necessary to start building your own septic tank with an individual determination of the capacity of the containers. The average daily water consumption by one person living in the house is taken as the calculation point.

An example of a calculation for a family of 4 people:

The average water consumption per person is 200 liters. A family of four will consume 800 liters per day.
The average duration of the wastewater settling period is three days.
Therefore, the total volume of the receiving containers is 2400 liters.
Taking into account unforeseen water inflows, add a supply and choose at your discretion 3 containers of 1 m3 or 2 containers of 1.25 m3.

Sewer pit preparation

The first step is to select a place for a sewer facility. It is planned at some distance from the water intake and the foundation of the house. The recommended minimum is 50 m from the water intake, 6 m from the base of the building and 3 m from the adjacent plot. Excessive remoteness from buildings will lead to an undesirable deepening of the septic tank: extra meters affect losses in gravity pressure, the construction of manholes, and clogging in long pipes.
Next, prepare the base of the pit. The length and width are taken according to the dimensions of the selected eurocubes with a margin of 15-20 cm around the entire perimeter for laying thermal insulation. The depth of the sewer pit is selected taking into account the height of the eurocubes and the slope of the common highway. The slope is taken in the ratio of 0.2 m per 1 m of the pipeline. 0.2 cm is added to the calculated value for concreting the bottom. fill concrete mix performed immediately after digging the pit. Fasteners for "anchors" are driven into a fresh solution. The eurocube must be held in the finished bunker and not squeezed out by groundwater.

The final stage is digging trenches. It is carried out in individual accessible ways. The focus is on laying the drainage system. Eurocube acts as an intermediate, preliminary treatment plant. The final treatment of wastewater takes place in soils, in pre-selected filtration areas. For these areas, a branched drainage system is withdrawn with a depth of at least 0.5 m. The length of each branch is up to 20 m. The optimal number of branches on loam for a waste volume of 800 liters is 2-3 channels.

Manufacturing. Assembly. Installation of a septic tank

A rational option for assembling a septic tank from eurocubes is the connection of 2 units of containers. Advantages of this choice:

Optimal number of connections between cameras.
Easy installation.
Small pit.
Easy choice of location for the pit.

It is necessary to prepare the following parts, equipment and accessories in advance:

4 pieces of tees with a pipe diameter of 100-150mm.
Pieces of pipes of the appropriate diameter.
Tool for cutting thick plastic.
Apparatus for metal welding.
Silicone or other sealant.
Drainage pipes, perforated, with a diameter of 50 mm. Quantity is determined individually for the project.
A prepared platform, flat, rising 20 cm above the horizontal.
Ropes or cables for lowering the septic tank into the pit.
Compass, caliper, chalk, centimeter, work gloves.

Work begins with sealing drains. For the narrow neck of the eurocube, which does not allow a tee to be placed inside the container, an incision is made along the diameter of the hole. In the future, the technological section is closed.

A hole is cut for the inlet pipe:

A distance of 20-30 cm is marked on the side of each container.
The center of the circle is marked.
A contour is outlined along the diameter of the tee.
Cutting is in progress.
A piece of pipe of the required size is cut off.
A tee is inserted into the hole and a pipe is attached to it.

The holes for connecting the Eurocubes to each other are cut out. Cut out a piece of pipe right size and with the help of tees, a connection is made.

A hole for ventilation is cut out on the horizontal surface of each eurocube; later on, a ventilation pipe connected to a tee will be placed in this “window”. Each of the pipe inlet/outlet units is equipped with a tee and a pipe for ventilation. The result is a eurocube with a branch pipe connected inside each container with a cleaning ventilation pipe by means of a tee.

The assembly of the septic tank is carried out according to the following principle:

The first container is placed on a pedestal or mound so that it becomes 20 cm higher than the second one. A hole is cut on the sidewall below the hole for the sewer by 20 cm. This operation is done to rationally use the volume of the second Eurocube.
Both eurocubes are connected by a pipe. Upon completion of the installation of pipes, the joints are carefully sealed. The use of sealant, preparation of the application site is carried out according to the instructions on the adhesive preparation.
The upper seam along the neck is fastened with special rivets, treated with sealant, and a waterproofing layer is welded to guarantee.
The structure is rigidly fixed with reinforcement and welded to the metal frame of the containers, the possibility of displacement of eurocubes relative to each other is eliminated.
On the surface of the second eurocube, a distance of 30 cm from the top point is marked and a hole for the drainage pipe is cut out.

Pipe joints are sealed with silicone or other special sealant.

The prepared septic tank is insulated. Styrofoam is used as an insulating material. The container is covered on the sides with pieces of PP and placed in a pit on the concrete bottom of the pit. Secure the septic tank with a cable threaded into loops.

The containers are filled with water to create the proper rigidity. Eurocubes are poured with concrete to provide protection against crushing by soil. Filling is done in portions, carefully so as not to damage the thin walls of the eurocubes.

Instead of a concrete solution, boards treated with an antiseptic composition can be used, or overlaid with profiled sheets.

In the end, the surface of the septic tank is covered with foam sheets or wooden flooring, covered with soil, only ventilation and cleaning pipes remain on the surface.

Drainage system laying

A do-it-yourself septic tank does not completely clean the drains without a drainage system. For it, perforated pipes with a diameter of 5 cm are purchased. The drainage system is routed from the outlet pipe of the eurocube and distributed over the entire aeration area. Pipes are covered with soil or gravel with a layer of 20 cm to ensure efficient distribution of water flow.

Installation of a septic tank at a high level of groundwater

For soils with a high groundwater level, the installation of a septic tank is carried out as described above. The difference is in the reinforced "anchoring" of the structure in the pit. The cable is selected strong, resistant to mechanical stress, having a high bending characteristic, resistant to corrosion and decay.

The aeration field is made bulk, in the form of a hill. The mound is decorated with a rock garden, to make it look like an alpine hill.

A third container is attached to the septic tank to create an additional filter block, or a small well breaks out next to the septic tank. In an additional compartment, a pump with a float-type switch is installed for pumping wastewater into an aeration field located above the rise of groundwater.

Turnkey septic tank

To hand over a turnkey septic tank to yourself is to check the pipe connections, their sealing. Ensure proper tamping or pouring of concrete. The concrete surface is smooth, without deep crevices. Perform a test run of a septic tank clean water. Check the efficiency of the filtration field and drainage system.

Several practical advice for the arrangement of a septic tank from eurocubes

Use perforated pipes of medium diameter for the drainage system. Make sure that the surface of the new pipes does not have defects, sags or incomprehensible inclusions.
Backfilling of drainage pipes is carried out with any soil, sand or a mixture of soils. But to protect pipes from silting, it is preferable to use crushed stone. It has high throughput and antiseptic properties.

On loamy soils, with a high level of groundwater, use an additional septic tank protector. Filtration well, specialized biologically active mixture, extended drainage system.
Closely monitor the septic tank and drainage system during a sharp drop in temperatures. Plastic at low temperatures becomes brittle, loses most of its thermal insulation properties, water will begin to stagnate and freeze. The septic system will fail. For prevention, use mineral or basalt insulation, wrap pipes close to the surface. Do not overfill the septic tank, drain the drain once a day.
Conduct sanitary cleaning and disinfection of the septic tank annually. Remove sludge from eurocubes, wash pipes, tees. The cleaning procedure is recommended to be carried out in the autumn. At this time, biological activity inside the containers begins to decrease, the release of microorganisms slows down or completely stops, and the unpleasant odor decreases.
It is worth starting cleaning with the release of the area under the ventilation and cleaning pipe from the soil. Handy equipment through the pipe opening removes liquid, silty, solid waste. Use them as organic fertilizer.
Flush the septic tank with water from a watering hose, pour boiling water over the joints, tees.
Assemble the structure. Seal the joints that are visible. Sprinkle with soil, tamp.

A self-made septic tank made of eurocubes will cost much less than a septic tank made of concrete rings. concrete rings less durable when used in aggressive environments. Eurocube plastic withstands the destructive activity of detergents. Acids and alkalis dissolved in drains do not corrode the surface.

Eurocubes are easier to maintain. They are washed, less lime inside. Severe frost with proper thermal insulation of containers will not lead to the destruction of the material of eurocubes.

Do-it-yourself septic tank from eurocubes

One of the simplest and most affordable options for a treatment plant for a house or a summer residence is a septic tank from eurocubes. Combined with good drainage, it will effectively clean drains and run smoothly for many years. Let's look at how to make a septic tank with your own hands from Eurocubes, in detail with calculations and step-by-step instructions.

For those who are faced with the problem of choosing a treatment plant, the question often arises: is it worth spending money on a septic tank when you can get by with an ordinary cesspool. It is possible, but it may not withstand large volumes of water from all sanitary facilities, and the aromas hovering around it are not always acceptable in a private area, especially in a small one. In addition, untreated domestic wastewater can pollute groundwater, then you can feel their smell or even a slight taste at the nearest well, and this will not please the workers of the sanitary and epidemiological station.

The design and principle of operation of a septic tank from eurocubes

A Eurocube septic tank is a single hermetic system that consists of one or more tanks. The sewer is connected to the first tank, and the effluents enter the tank, where they are rough cleaned.

The effluent clarified in the second tank is approximately 60% free of impurities. Further, the water goes into the drainage system, where it undergoes soil post-treatment. As a result of fermentation, a certain amount of methane, carbon dioxide and hydrogen sulfide is released in the first and second chambers, they are removed through the ventilation pipe. Fluid is pumped out by a cesspool machine through a cleaning pipe.

The main element of the treatment plant is the eurocube

Norms and rules for the location of a septic tank on the site

The basic requirements for the installation of a septic tank are formalized in building, sanitary norms and rules, these are the main documents that determine the installation of a treatment plant, taking into account adjacent buildings and the characteristics of the territory. Before installing treatment facilities in a private house or country house, it is necessary to prepare and approve the project in the relevant organization.

During the construction of septic tanks, it is important to pay attention to some features of its installation in certain conditions.

The installation depth of the septic tank, no matter what design it will be, should not be less than the soil freezing limit, if the requirement is not feasible, the septic tank must be insulated.
The soil must have high permeability, sandy and

gravel soils. In the case of clay soil, the construction of cesspools and the installation of a pump will be required.

If there is not enough territory on a private plot

for ground filtration, the construction of an aeration well will be required.

When placing a septic tank on the site, it is worth considering that, like for cesspools, it will need to be pumped out and you need to take care of the possibility

Calculation of the capacity of the septic tank

According to SNiP 2.04.03-85 “Sewerage. External networks and structures” per person, the volume of water consumed is about 150-200 liters per day.

Stages of installation of a septic tank from eurocubes

Sewerage with a septic tank from eurocubes differs from other treatment facilities in that additional arrangement will be required

s, but with proper installation, such a design will be a reliable and durable solution in a private house or in the country.

Before proceeding with the installation work, they think over the design and location of the septic tank on the site, decide which one is better to install so that the sewerage system in a private house is functional and coordinate the plan in the SES.

Preparing a pit for a septic tank.

Anchoring will protect the structure from displacement in the event of a groundwater breakthrough.

The next stage of earthworks will be the digging of cesspool trenches for a filtration field or well. Work may vary depending on the chosen method of soil post-treatment.

Septic tank drainage system

Soil treatment can be organized in several ways.

Filtration wells - a simple and inexpensive construction, is a well, the bottom of which is made in the form of a filtration cushion of sand and gravel. But it is forbidden to install it on many types of soil: sandy loam, sand, fractured soils and loams. The productivity of the wells is small, and the installation must be coordinated with the sanitary and epidemic service.
Underground or ground filtration fields are a kind of irrigation system through which wastewater processed by a septic tank passes and enters the soil. Arrange a system of ceramic or plastic perforated pipes laid on the filtrate. At the end of each channel, a ventilation riser is brought to a height of up to 0.5 m.

Filtration trenches are pits up to 1 meter deep, in which pipes more than 30 meters long are laid, through which water flows by gravity into the existing network or storm sewer.

Assembly and installation of a septic tank

The septic tank is assembled according to a pre-designed scheme, adhering to the basic rule - all connections must be absolutely tight, builders have no consensus on which sealant is best to use.

The assembly begins with the preparation of the first container. From the upper edge of the eurocube, 20 cm recede down and make a hole for the pipe, which will connect the treatment plant to the external sewerage system. On the opposite side of the cube, at a distance of 30 cm from the top, a second overflow hole is made, through which the drains will pass into the second container.

On top of each tank, it is necessary to organize a cleaning hole and a ventilation duct. As a rule, only one hole is made from above, and a pipe is fixed in it for cleaning, and the ventilation riser is brought out using a ready-made filler hole. The pipe is selected with the appropriate diameter and raised to a height of up to 2 meters. Be sure to take into account the fact that the ventilation pipe should not be lowered into the tank below the overflow pipe.

Advice! If the ventilation riser is made collapsible, then in the future, liquid can be pumped out of the septic tank through it and an additional hole and pipe outlet for cleaning will not be required

Besides homemade septic tank must be protected from crushing. To do this, it is filled with water and the gap between the system and the wall of the pit is concreted. They also practice simpler and cheap option protection, along the perimeter of the structure, a box is made of boards impregnated with an antiseptic, and the earth covered between the septic tank and the walls of the pit is carefully tamped.

Maintenance of septic tanks

In order for the septic tank, and, accordingly, the sewerage in the house to work smoothly, it is important not to overfill the tanks and follow some simple rules.

If you need to pump out the content in

for preventive purposes, it is better to do this in the fall, at this time the biological activity of microorganisms is lower and the unpleasant odor is not so pungent.

When evacuating the contents of the septic tank, some of the accumulated sludge is left at the bottom,

to ensure further normal filling of the chambers with active bacteria.

The contents of the septic tank are being pumped out

sewage equipment, so you should take care of the entrance in advance.

If you additionally make special mixtures of bacteria for septic tanks and cesspools, pumping

needed less frequently.

After installing a septic tank into the sewer, it is categorically not recommended to lower rags, matches, napkins, hygiene products and even toilet paper.

How to make a septic tank from eurocubes with your own hands - detailed photo-installation instructions

Rest in the country is pleasant only if all the benefits of civilization are present there. For modern man the presence of running water and sewerage is one of the criteria for comfort. And if there are no problems with this in apartment buildings, then in the private sector, residents have to look for a way out of this situation. Sometimes, wanting to save money, people equip an ordinary drain pit. In this case, apart from the cheapness of construction, there are no other positive aspects. It is much better to build a septic tank from European cubes with your own hands, which will serve you for a single year. Moreover, it is one of the most simple ways arrangement of sewerage in a country house.

What are the advantages of a septic tank over other designs?

preventing the spread of an unpleasant odor;
lack of soil contamination with human waste products;
uselessness in the services of sewers, cleaning the septic tank is carried out quite rarely and can be done independently;
A septic tank will last much longer than a cesspool.

Choosing the right container size

The size of the septic tank is selected depending on the number of drains. Their volume is determined depending on the period of operation and the number of inhabitants in the house. For temporary use in the summer, a small-volume design is suitable, and year-round use of a septic tank involves daily discharge of effluents.

Their volume is determined by the number of people living in the house. It is assumed that the daily consumption of water per person is 200 liters. Focusing on this value, determine the daily water consumption for all residents. The volume of the septic tank chamber should be three times larger than this figure. It is advisable to choose a slightly larger septic tank, taking into account the unforeseen increase in drains.

Where is the septic tank located on the property?

It is necessary to locate the sewer facility away from the place of water intake. The minimum distance is 50 meters. When installing a septic tank, it is necessary to move at least 6 meters from the foundation of the building, but it should not be built too far from the building either.

The layout of the septic tank in relation to other objects

Since the sewer must have a sufficient slope, each extra meter leads to a decrease in the installation level of the septic tank. In addition, in a long pipeline, there is a high probability of blockages. To eliminate them, you have to build manholes. Also, you should not place the septic tank closer than 3 meters to the neighboring area.

Preparing the pit and base for installation

To build a septic tank from eurocubes, the first step is to prepare a pit for containers and a trench for sewer pipes. The size of the pit for the septic tank is taken from the calculation of the volume of the installed cameras plus 15 centimeters on each side. The depth of the pit depends on the size of the eurocubes and the slope of the sewer line, which must be at least 2 centimeters per meter of pipeline.

The bottom of the pit is fifteen centimeters poured with concrete. During this process, you need to make loops to "anchor" the cubes so that they are not squeezed out by groundwater. A trench is being dug from the house to the installation site of the septic tank. The trench should slope towards the septic tank.

Preparation of eurocubes for further installation

Before starting work, the containers must be prepared. At this stage, the drain is sealed at the bottom of the tank, and holes are made in the eurocubes themselves for inlet and outlet pipes and ventilation.

The drain at the bottom of the Eurocube must be sealed to prevent seepage of drains

To prepare 2 eurocubes for use as a sewer, you will need four tees and pipe sections (d = 10-15 cm). To insert a tee, an incision is made around the neck in the shape of the letter P and the edge is bent.

In order to insert a tee into the container, you need to make a cut. Its size must be sufficient for the passage of the tee

In the first cube, you need to make a hole for the pipe coming from the house. A piece of pipe of the required length is cut off, inserted into the resulting hole and connected to the tee.

A sewer pipe from the house is fed into this hole. When connecting pipes, do not forget to check the presence of rubber bands

The tee is inserted into the tank and connected to the inlet pipe

For ventilation, a hole is cut above the tee and a piece of pipe (d = 5 cm) is inserted. On the other side of the container, an outlet is made, which should be located below the inlet. In another European cube, the same hole is made, but taking into account the fact that the cube will be located 20 cm below the first one. This is necessary for the full use of the volume of the second container. Tees must be connected to the pipe connecting both tanks, on top of which ventilation outlets are installed.

On both sides of the pipe connecting the tanks, it is necessary to connect tees and install ventilation outlets

A hole is also made for the drainage pipe leading to the aeration field. After all pipes are installed, the joints should be treated with a sealant.

All connections must be carefully treated with sealant

The seam around the neck is fastened with rivets and also treated with sealant. A waterproofing layer is welded on top.

A waterproofing layer is welded onto the cutout around the neck

To prevent the containers from shifting relative to each other, they must be securely fastened to each other. For this, the frames of the Eurocubes are welded together. For more durable fastening, reinforcement is used.

After the eurocubes are firmly fastened together, they are ready for installation.

Installation of eurocubes in the pit

Prepared eurocubes are installed in the pit and attached to the prepared loops with a cable. Where soils tend to swell, containers must be protected. To do this, you can lay a professional sheet or boards treated with an antiseptic on all sides, or fill the distance between the soil and the walls of the cubes with concrete. In this case, the frame of the tanks will serve as additional reinforcement. Before pouring concrete, the containers must be filled with water, and the process itself must be carried out gradually and very carefully.

Note! The walls of the eurocube are very thin, so the process of pouring concrete requires extreme caution.

Using foam, the walls of the containers and the top are insulated. The entire structure is covered with wooden rolling or concreted.

The walls and top of the eurocubes are insulated with foam. This will help prevent freezing of the septic tank in cold weather.

In any case, such a home-made septic tank from Eurocubes does not completely clean the drains. Therefore, for complete cleaning it is best to equip the drainage field. Only in this case the sewer system will be complete.

How to make a septic tank from eurocubes with your own hands - installation rules

We make a septic tank from European cubes with our own hands. Sequential description of the process. We install a homemade septic tank from eurocubes.

Independently made and efficiently operating LOS (local treatment facilities) are of great interest to the users of our portal. For example, with a low GWL, it is often used.

An attempt to implement this scheme on poorly draining, heaving soils, with a high level of groundwater, can end in failure. The rings can move during the seasonal movement of the soil, and the tightness of the septic tank will be broken, and the drainage well (which is placed without a bottom) or filtration fields will constantly flood. The use of purchased plastic treatment plants in a water-saturated “problem” area can also lead to the fact that, when the soil is heaving, the buried system is pushed out or squeezed by the walls.

In this regard, an interesting scheme for the implementation of a surface septic tank from eurocubes on the "swamp" of the FORUMHOUSE user with the nickname Globi.

Globi Member FORUMHOUSE

I have in the area high level ground water. Do not make a conventional septic tank. Having looked at the ordeal of a neighbor (for the second season after the winter he is trying to “drown” the floating VOC all the time), I decided to make a surface treatment system based on 2 eurocubes.

The system attracted close attention of users who faced a similar problem of high GWL. But, having decided to build this scheme, you should immediately think about where to divert the drain after the septic tank. Often the problem of post-treatment and further disposal of "black" waters in a wetland, with insufficient soil absorption capacity, turns into a real "headache".

How I solved this problem globe, we will tell a little later, but now we will describe the design of a surface septic tank. To assemble it, we need:

Eurocubes - 2 pcs.
Material for the construction of an extension to the house in which a septic tank is mounted: boards - 10 pcs. section 100x25 mm, sheets of flat slate 1 cm thick.
Material for insulation of the box - expanded polystyrene (polystyrene) - 10 sheets.
Decking for the roof of the "house" under the septic tank.
Small things - sewer pipes, special sealing cuffs for a septic tank, tees, hardware.

Globi

Eurocubes cost me 3,500 rubles per 1 piece. (at 2012 prices). For the material for the "sarcophagus" I gave another 4100 rubles. Pipes and bends cost 3500 rubles. + any small things and building materials in the form of hollow concrete blocks, cement, metal mesh to reinforce the base for a septic tank. I spent about 17 thousand rubles on everything about everything.

The design of the annex can be changed in accordance with the size of the septic tank and the availability of certain building materials.

The main thing - when mounting a surface septic tank, remember that all connection points for plumbing equipment - a toilet bowl, sinks, a bathtub - must be higher than the entry point into the tank.

It is necessary to observe the required slope of sewer pipes (2 cm per 1 linear meter, with a diameter of 110 mm). If the height of the floor of the first floor (from ground level to the floor) does not allow to withstand the slope of the route, then you will have to think about how to “throw” waste into the septic tank, for example, using a fecal pump.

The installation process of the septic tank is clearly visible in the following photographs.

We pour the base from concrete, and then we install the system, not forgetting to check it for leaks at the end of the assembly to make sure that after launching the septic tank will not “smell” being near the house. For this Globi used car compressor, having previously muffled the outlet with a standard plug, and put a plug with a fitting from the accumulator at the inlet.

Globi

He rocked for a long time until one of the plugs flew out with a loud pop. The system is sealed, there should be no foreign unpleasant odor. Next, I will mount the ventilation pipe and think about how to ventilate the box itself so that bacteria do not die in the septic tank due to overheating in the summer.

When checking containers for leaks under excessive pressure, the main thing is not to get carried away with the process, otherwise the plastic cube may break.

To build a system, you need to understand the principle of its operation. According to the user, he thoroughly rummaged through the Internet to find out about the main nuances of the functioning of the septic tank. The basis of the whole system is correct overflow, from one eurocube to another, and further discharge of runoff into drainage.

When waste enters the septic tank, it is separated. Part of the solid waste immediately goes to the bottom or settles after some time, having passed through settling. Then the liquid is poured into the next container. In this case, the liquid in the next tank from the previous cube must be taken so that the overflow is one third below the level of the water surface in the tank. This will cut off solid inclusions floating on the surface.

Globi

I deviated from the classic overflow scheme. This allowed us to save on cleaning. In principle, they are not needed. Because the septic tank is not buried, at any time you can disassemble everything and clean the pipes.

For example, in this design, the entrance to the septic tank is cleaned directly from the house. For this, there is an inspection hatch. An overflow between the first and second containers is also available, it is enough to remove the wall (slate sheet screwed onto the screws) and disconnect the adapter to the ventilation pipe.

The exit from the septic tank is cleaned from the outside - plumbing cable through a tee.

You also need to ensure proper ventilation of the septic tank. For this (it is brought out as high as possible, for example, to the ridge) and a supply pipe that ensures the flow of air into the system. Such a pipe is usually placed at the end of the filtration / aeration field, on drain pipe.

The fan pipe provides communication between the sewer system and the atmosphere, and also prevents the appearance of an unpleasant odor in the house and the disruption of water seals.

One of the main elements of the system is a drainage tunnel. The user made it from an old bathtub buried at a depth of 0.5 meters. He put it on concrete blocks (around the entire perimeter) to increase the volume of a home-made infiltrator - an inverted container without a bottom. From above, the bathtub is insulated with foam plastic and sprinkled with earth. The input of the drain is carried out through the hole in the bath.

The infiltrator is needed for post-treatment of the drain.

Globi

Operation has shown that the drainage does not freeze through.

Another question that worried many who decided to repeat this septic tank was whether it would freeze in winter.

Practice has shown that the insulation of the box with foam plastic 100 mm thick is sufficient for normal operation under negative temperatures. It should be borne in mind that the wall of the house, to which the containers are facing, is warm. During the activity of bacteria (fermentation process), heat is released. Additionally (just in case), the user placed an electric heater with a power of 0.5 kW from below, on the right side of the tank. During operation, even at -18 ° C, the septic tank did not freeze, but A heater is really needed only in severe frosts..

To increase the efficiency of the cleaning system, Globi launches a purchased bioactivator into it - microorganisms, flushing them down the toilet once a month.

Another question is whether the volume of 2 eurocubes is enough or is it better to put 3 pcs.

Globi

The volume of the septic tank depends on the number of people living in the house. In addition, eurocubes come in different sizes. Mine are 700 liters. Effective volume - 550 liters each. Total - 1100 liters. This, of course, falls short of the recommended norms for 2 people, especially if there is a volley discharge, but I have 2 bathrooms in my house - with compost and dry closets, and a shower with its own drainage. If necessary, then over time it will be possible to supply 2 more Eurocubes. It's easy, because you don't have to dig anything.

A septic tank from eurocubes is an effective autonomous system for removing waste and sewage. It provides a comfortable life of a person in a country house, where there is no central sewerage.

Sewer construction from eurocubes

The cubes that we will use to make a septic tank are made in the form of containers made of polyethylene resistant to chemical compounds. Such material in contact with an aggressive environment completely retains its mechanical and physical properties. Containers are placed in a welded frame made of metal profiles. The volume of eurocubes is different - 640-1250 liters. From the inside, the described containers are additionally reinforced with special shields (they are placed in the corners).

Due to this, polyethylene containers resist operational abrasion well. Eurocubes have other advantages. They are: completely sealed; can withstand due to the presence steel profiles and ergonomic cubic configuration, serious load; resist the influences of the external environment. Such containers are originally made for long-term storage and transportation of aggressive substances. Therefore, they can be called ideal for the construction of an autonomous.

A septic tank from eurocubes is characterized by a number of advantages:

high speed of building a system with your own hands;
the opportunity to purchase used containers at a minimal cost;
ease of operation and maintenance;
excellent waterproofing of containers and their durability;
a small amount of preparation work plastic containers under the cleaning system.

The disadvantage of Eurocubes is their relative lightness. If flood waters flood your suburban area, they may well “float” to the surface of the soil. This can be avoided by attaching the tanks to the concrete base with tie-down straps and cables. Also, Eurocubes with thin walls can be deformed under the influence of increased loads. Such containers are not recommended for arranging a septic tank.

perform thorough waterproofing of containers;
correctly choose the place of their installation, taking into account the terrain in order to reduce the influence of heaving soils on the stability of the septic tank;
tie the containers to each other with steel bars;
protect the cubes from strong squeezing (completely concrete the moat for the country sewerage or make the lining of containers out of boards).

Such events significantly increase the efficiency of functioning and reduce all its "minuses" to a minimum.

Country sewerage without pumping out effluents - device diagram

Having made a septic tank from Eurocubes with your own hands, you will have at your disposal a reliable and fairly environmentally friendly “mini-sewerage”. Its work is based on the separation (mechanical) of large waste particles present in wastewater. It becomes possible thanks to the two-level design of the septic tank, which provides the so-called "overflow phenomenon".

The scheme of the system functioning looks like this:

From the plumbing equipment, wastewater goes through pipes to the first container. It separates heavy fractions, which sink to the bottom of the plastic container.
When the level of waste reaches a certain level (its value depends on the volume of eurocubes used), they are moved to an adjacent container. The overflow of large particles is ensured by the fact that a certain height difference is provided between the tanks.
The waste from the second container is discharged into the ground through the drainage pipe. The pipe, note, is mounted about 20 centimeters higher from the bottom of the tank. At its end must be mounted check valve. It prevents the possibility of backflow into the sewage pipe.

Often, special biological activators are added to eurocubes. They form a special environment in the tanks that effectively breaks down wastewater. The use of activators ensures the production of waste with a minimum volume of undissolved fractions (no more than 0.5% of the total amount of wastewater). Due to this, waste water enters the ground, which environment does not cause any damage.

It is possible to improve the cleaning system for summer cottages that does not require waste pumping by building filtration fields in your suburban area or a drainage well. As you can see, to make a truly effective " private sewerage» for giving it is quite real.

Preparatory stage - we take into account all the little things

You will be able to build high-quality sewage without pumping if you correctly select the volume of containers and choose a place to install the system, as well as purchase all the necessary tools and materials. First you need to decide on the place where you will build a septic tank from Eurocubes with your own hands. Choose it so that:

the septic tank was located at a distance of more than 5 meters from the house, and 2 meters from other buildings;
it was possible to ensure that the slope of the sewer pipe per meter was at least 2 centimeters;
it was possible to freely approach the containers for their maintenance;
the pipeline did not have bends (if it is impossible to do without them, it is necessary to install intermediate wells).

In addition, it should be understood that the excessive removal of the septic tank from a residential building will require you to spend a lot of money on the construction of an extended pipeline. And the large length of the pipes contributes to the formation of blockages in them, which you will have to clear. Therefore, it is not necessary to build a septic tank without pumping out at a distance of more than 15 meters from the house, even when the area of your suburban area allows you to do this.

The volume of containers is selected according to the number of sanitary equipment installed in the house and the number of permanent residents, as well as the activity of using sanitary equipment. If you are in the country only in the warm season, it is enough to take Eurocubes with a volume of 650–800 liters. But when people live in the house all the time, it is better to install more capacious containers. According to existing standards, one person consumes about 200 liters of water per day. A septic tank is recommended to be installed three times larger in volume.

So, if 3 people live in the house, you will need to make a septic tank of two cubes with a total volume of 1800 liters. This is quite enough for a comfortable life in private housing construction.

Getting to work - preparing a pit and containers

We will install plastic eurocubes in the pit. It must have certain geometric dimensions. Determining them is simple - add 15 cm in length to each side of the containers used. And dig a pit for the received parameters. A gravel cushion should be made at its bottom. Then pour a concrete solution on it (up to 0.3 m thick) and immediately mount metal loops into it. They will be needed to secure containers.

At the stage of excavation, it is also necessary to dig trenches. In them you will lay sewer pipes. Please note - it is necessary to provide for a slight slope of the trenches towards the installed wastewater collection and treatment system. Now you can start preparing the containers. In them, we need to make several holes for ventilation and pipes (inlet and outlet), and the drains in the lower parts must be carefully sealed. If you are installing a system with two cubes, you need to stock up on four 10-15 cm pieces of pipe and tees. The latter are inserted into containers as follows:

make a cut around the necks of the containers (it should look like the letter P);
bend the edge;
install tee.

Next, make holes on the sides of the containers. Pipes will be connected to them. In the first eurocube, a sewer pipe will be connected to the hole. It will tie together the internal system and the septic tank. The connection is made quickly and without difficulty - cut the tubular product of the desired length, feed it into the hole and attach it to the tee. Be sure to seal the joints of the individual elements of the system! An air vent must be provided above the tee. A pipe with a cross section of 5 cm is usually inserted into it, no less.

On the other side of the cube, another hole is made - the outlet. It should be somewhere 0.2 m below the first. Make the same hole in the second container. Then connect them with a pipe - use tees. Above them, you also need to equip exits for ventilation. After that, you need to weld the cases of eurocubes together (it is allowed to additionally use reinforcing bars). Due to this, the containers will not move relative to one another. And then you need to close up the necks of the cubes, fasten them (as firmly as possible) with rivets and coat them with sealant.

We install a septic tank - sequential assembly

After the concrete has dried in the pit, we lower the eurocubes into it (do not forget that they should already be fastened together) and fix them with a cable to the loops mounted at the bottom of the pit. If the soil on the site is unstable, and there is a possibility of flooding, sheathe the containers with boards or a sheet profile. It is also allowed to fill the gap between the ground and the walls of the cubes with a concrete solution to increase their stability.

But concrete should only be poured after you fill the containers with water. The next important stage of work is the insulation of eurocubes. Such an operation must be carried out without fail, otherwise aerobic bacteria will not be able to decompose effluents at low temperatures. Insulation of containers is most often carried out with polystyrene foam plates or pieces of foam.

You just have to lay a layer of insulation on the surface of the septic tank and cover it with earth, leaving only the outlets of the pipes (cleaning and ventilation) on the surface, and lay perforated pipe products for drainage. Their recommended diameter is 5 cm. Drainage is connected through a tee to the outlet pipe of the second Eurocube, and then it is covered with gravel (a layer of about 20 cm) to eliminate the risk of system silting. Your country septic tank ready!
