For the manufacture of homemade septic tanks they use various materials. One of the best in many respects is Eurocubes. These are sealed plastic containers designed for transporting or storing liquids. Buying them is not a problem; used ones are also sold, which, after a little modification, do an excellent job of cleaning drains.

To manufacture, you do not need to be a specialist or have professional tools. Every man can make a septic tank from Eurocubes. Any options are available: from two, three containers, with or without pumping. After reading the article, you will be confident that such a system is reliable, inexpensive, and easy to maintain.

It was no coincidence that those who wanted to build a septic tank on their own paid attention to Eurocubes: very convenient for installation rectangular shape, good capacity. The small thickness of the walls is compensated by steel sheathing that can withstand loads. A used technical Eurocube can be purchased for 3.5 thousand rubles (this is in Moscow), in other regions it is even less or several times more expensive

In many respects, Eurocubes are ahead of other materials that are traditionally used for homemade septic tanks:

The advantages of Eurocubes also relate to operational properties and ease of installation:

Products	Difficulty of installation	Possibility of installation at high groundwater level	The need for protection from aggressive environments and sealing
Eurocube	Deformed in the absence of a frame	Can be installed by one person	Install	Not required, seal the pipe entry points
Plastic barrel	Frozen soil can squeeze out of the ground	Manually	Maybe	Not necessary, seal joints with pipes
Metal barrel	Quite stable, but minor deformation is possible from excessive loads	Without special equipment	Acceptable	Sealed, requires treatment with anti-corrosion substances inside and outside
Concrete rings	Withstands ground pressure	Requires winch or lifting equipment	If deeper than 2 m	Seams are sealed, treated with bitumen or other means on both sides

In front of everyone positive qualities Eurocubes have disadvantages when used as a septic tank. High groundwater can push the structure to the surface. To prevent this from happening, they do concrete foundation, the structure is attached to it.

Preparing to install a septic tank

Eurocubes are available in volumes of 640–1250 liters. You should calculate which tank is suitable for your family. It is not advisable to take the norm of 200 liters per day for calculation - often much more is actually used less water. Complete filtration occurs in 3 days. The most common version of the Eurocube is 1000 liters. To prevent the liquid from overfilling the containers, install 2 or more reservoirs.

Scheme of a septic tank from Eurocubes

Choose an installation location, trying to ensure that the pipes are located without turns, otherwise the risk of clogging increases. First, they dig a trench under the pipeline, from which the waste flows into the receiving chamber. Depth below freezing point. Then they make a pit for the septic tank, adding about 20 cm to its dimensions on all sides. This is necessary for insulation and backfilling.

If there are no turns and the correct slope of the pipes is 2 cm per linear meter The trench depth is allowed above the freezing point. Water and heavy fractions will not be retained, and the threat of freezing is eliminated. If it is necessary to make a turn, it is performed at an angle of 45°, but not 90°.

Eremtsov A.V., engineer at Septic-Stroy company

A trench is dug from the first reservoir to the second. The wastewater in such a septic tank is purified by a maximum of 60%, which is not enough to pump out without causing harm to the soil or reservoir where the discharge will be made. Additional purification of the liquid is required, which is carried out in one of the following ways:

• arrange a filter well;
• construct a drainage field;
• make filter mounds.

When choosing an option, it is important to find a free site for the structure.

In the pit for the septic tank, an additional 0.2 m is provided for the device concrete platform. When pouring, metal hooks are installed. The Eurocube is then secured to them with straps and cables. This is necessary to prevent groundwater from squeezing out the tank.

Refinement of Eurocubes

To install the system you will need:

• Eurocubes – 2 or 3 as desired;
• tees - 3 or 5 depending on the number of tanks;
• pipes for sewerage and ventilation;
• sealant, polystyrene foam;
• tools: welding machine and Bulgarian.

The conversion of Eurocubes for septic tanks is carried out in the following sequence:

1. Unscrew the drain plug from the bottom of the container, apply sealant to the threads of the pipe and tighten it. This will prevent possible leakage.
2. Make a hole in the first tank at a distance of 20 cm from the top for the input pipe. A hole is cut in the opposite wall for the outlet, which is 5–10 cm lower than the input one. A similar operation is done with the second container, placing each hole lower.
3. The cubes are connected with a short pipe and tees are installed at the ends. So that they pass through the neck, they make an incision with a grinder and wrap the plastic.

Andrey from Yaroslavl region says that in the second European Cup he made holes at the same level as in the first. I installed the second tank 10 cm lower than the first - the useful volume in both tanks is the same.

The frames of the Eurocubes are tied together with steel rods, reinforcement, strip iron, and corners to give the structure greater strength.

The modification is completed by cutting out a hole for ventilation. They are made exactly opposite the tees to be used for cleaning if necessary.

Installation

The structure is lowered into the pit and anchored on reinforcement protruding from the concrete. The underwater and outlet pipes are inserted, a tee is mounted on the first, but it is not needed for the latter. Instead they install check valve so that groundwater and melt water do not enter the chamber.

The pipe entry points are sealed, and plumbing tape is additionally used. Waterproofing is installed on the upper part of the structure. Special attention pay attention to the slots made to install the tees. It is advisable to melt their edges along the cuts with a soldering iron and connect them or use suitable glue.

The sides and top are insulated with foam plastic, the required thickness is 10 cm.

Fill the tanks with water so that they do not become deformed during subsequent work. The remaining space is filled with clay mixed with dry cement. Boards are laid on top and covered with earth. Instead, profiled sheets and flat slate work well.

Features of the device at high groundwater level

If the water comes close to the surface, some changes are made to the usual installation scheme. First, determine the depth of the groundwater. To do this, drill a hole 2 m deep in the ground and leave it for a day. If the walls are dry, the water lies deeper.

Advice. When there is a well nearby, it is not necessary to drill a well. The water level in the well corresponds to the depth of groundwater.

If groundwater is located closer than two meters to the surface, additional measures are required. The site must be concreted. In other cases, you can do without this - just compact the soil well, add sand, and drive pins into the soil for anchoring.

Concreting, when groundwater is very high, is also necessary on the sides of Eurocubes. The solution is poured in small portions, wait until the previous layer has set, and only then continue working. This is required so that the mass liquid solution did not push through the thin walls of the tank.

Important. Replace concrete with corrugated sheets, flat slate, even with boards it’s risky. They may not withstand the pressure, the thin plastic will crack.

At high groundwater level the device drainage well impossible. There are 2 options for solving the problem: forced pumping of liquid with a pump or drainage system on a hill. The first method is inconvenient: you need to constantly monitor the level, the liquid is poorly purified, and can only be discharged into a ditch, but not into a reservoir or for watering the area.

Drainage field

These are perforated pipes with a diameter of 110–160 mm, communicating with each other and arranged in parallel. From them, water goes into the soil. The installation depth is above ground level.

Drainage field on the site: pipes above the level groundwater

They make an additional tank. You can use another Eurocube so as not to seal a structure made, for example, of concrete rings. It is installed drain pump, are equipped with a float switch so that the unit operates in automatic mode.

A pipe with a diameter of 25 or 32 mm is laid underground at a shallow depth to the drainage field. To prevent liquid flow, a check valve is installed at the outlet.

Filtration cassette

This is a plastic or reinforced concrete container without a bottom, which is also called an infiltrator. Installed on the surface, the wastewater, after treatment, goes into the soil without polluting nearby groundwater. One medium-sized cassette replaces 0.8 tons of crushed stone or more than 30 m of perforated pipe.

Fertile soil is removed from an area that exceeds the dimensions of the cassette by 0.5 m on all sides. A pit is required to be no more than 0.5 m deep. A continuous reinforced concrete fence is made along its perimeter, equal in height to the trench. The bottom is covered with fine crushed stone, and a cassette is installed on top. Connect a hose or drain pipe.

Non-standard solution– used instead of a purchased cassette old bath. Under it is crushed stone 40–70 mm in a layer of 20 cm.

Covered with earth. The design looks beautiful alpine slide. In this design, the liquid will not freeze.

Answers to frequently asked questions

Question No. 1. How to pump out from a septic tank - through a ventilation pipe?

Yes, because the manhole cover is underground and accessing it is a hassle. They just take into account that the diameter of the hose of a sewage disposal machine is 110 mm, so the ventilation is made of 160 mm pipes. You can install the same pipe on the hatch (its diameter is 150 mm), but ventilation is still necessary.

Question No. 2. Fixing the pipes with sealant seems somehow unreliable, is there another way?

Stores sell special cuffs for sewer pipes; in this case, sealant is used for sealing.

A septic tank made from Eurocubes is a sealed structure for cleaning used dirty water. It is installed on personal plots where there is no centralized sewage system. It is more convenient and more efficient than a cesspool. IN lately Many people are interested in the device and how it works.

Why is a septic tank made from Eurocubes popular?

Human life is associated with observing the rules of hygiene: washing clothes, washing dishes and food, cleaning premises, bathing, visiting the restroom. This necessary activity leads to the formation of wastewater. A septic tank made from Eurocubes helps to arrange conditions at a modern level. It has a number of advantages:

1. Made from thick plastic.
2. It has a simple and compact design.
3. Prevents the appearance of unpleasant odors.
4. Filters wastewater.

What is a Eurocube

This is a container with rectangular edges made of white, blue or black plastic. Each has holes that are used in the system for collecting and draining liquids. The Eurocube under the septic tank is buried in the ground, where it is subjected to pressure, but the reinforced plastic does not lose its tightness during prolonged use. Its strength is enhanced by rigid ribs and metal frame, which increases the reliability of products.

The walls of the cube are able to withstand the load and not deform, even if sewage is fed under pressure. The cube material does not interact with aggressive substances and does not change properties due to changes in temperature and humidity. Cracks do not appear in the housing due to mechanical stress. You don’t have to worry that harmful waste will end up in the environment.

Main parts of the Eurocube:

• 1) Plastic walls.
• 2) Filling pipe with a cover, its diameter is 150 mm.
• 3) Ventilation valve, it is next to the filler neck.
• 4) Drain tap, located at the bottom.
• 5) Metal sheathing, which contains a plastic container (flask).
• 6) Pallet made of metal or wood.

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

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

1. The wastewater enters the first chamber, where large debris is screened out.
2. After rough cleaning, the sewage enters the chamber with biological products. Here organic matter is processed by microorganisms.
3. The liquid enters the filtration field for finer purification.
4. Purified water is released into the soil on the plot.

There is no need to create a filtration field for thorough cleaning. After passing the main stages, the effluents lose bad smell and become safe for nature.

Important Calculations

It’s easy to build a septic tank from a Eurocube at your dacha with your own hands. Before starting work you need preliminary calculations and preparatory work.

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 to the nearest whole number. The table shows the standards and calculation results for cubes with a volume of 1 m3.

№	Water consumption per day per person, l	Number of people in the family	Volume of water consumed per day, l	Volume of water consumed in 72 hours, l	Number of eurocubes for a septic tank based on volume, pcs.	Number of eurocubes for a septic tank, taking into account the biochamber, pcs.

8	300	2	600	1800	2	3
9	300	3	900	2700	3	4

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

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

Design

You cannot arbitrarily build a septic tank even on own plot. It must comply with sanitary and building regulations. The distances from the designed treatment facility to the nearest site facilities are taken into account:

• 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 capacity, freezing depth, and relief features 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 at turns they make inspection wells. Free access for sewer trucks is also provided, who will periodically inspect and clean the septic tank of sludge.

Marking, excavation and foundation

You can learn the technology of how to make a septic tank from Eurocubes with your own hands, then complete the work processes, but first you will have to perform several simple and important steps.

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 greater than the height of the cube by 0.5 m, excluding the top embankment. If possible, the first container is placed below the freezing depth of the soil.

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

Soft soil can sag under the weight of full flasks, which will result in the seal being broken at the joints. Do the backfilling, compaction and concrete pad more carefully.

Connecting Eurocubes into a system

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

The cubes are placed at a distance of 20 centimeters, connected with metal parts or welded. There should be a single rigid structure. Treat the connections between the pipes and the walls silicone sealant and liquid waterproofing.

Insulate the outer surface of the cubes and the pipeline mineral wool or polystyrene foam. Connect the sections of the system so that the liquid flows freely. Fill the system with water to check for leaks 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.

Backfill

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

1. Prepare a mixture of sand and dry cement 5:1, then pour it in layers into the grooves between the walls of the pit and cubes. Water each layer with water.
2. Pour liquid concrete using the sheathing of Eurocubes as reinforcement.
3. Insert sheets of corrugated sheets or slate around the cube along the perimeter of the pit.
4. Connect the concrete pad reinforcement to the system frame.

Choose the method that is optimal in terms of price and soil and climate characteristics. Cover the system with insulation made of polystyrene foam and penoizol on top, fill and level the soil.

Bacteria

Waste creates an environment for rotting and unpleasant odors. 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 fertilizer. The septic tank works more efficiently with microorganisms, less cleaning is required, and there is no smell. Stores sell formulations suitable for processing contaminants that differ in composition and conditions.

Perfect cleaning

It is possible to improve the purification of water after it passes through the septic tank. Dig a filtration well and fill its bottom with sand and gravel. This way the water will undergo natural purification and gradually seep into the soil. Or make a filtration field, it resembles an irrigation system. The wastewater will circulate through pipes with holes, gradually seeping out and at the same time irrigating the soil.

To construct 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 with a diameter of 100 mm. At the end of each water pipe, make a riser for ventilation.

Design solutions

Use plastic containers to enhance an existing system or in conjunction with concrete rings. You can make a septic tank with your own hands from one Eurocube, but in design 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 a Eurocube and place it on a bed of sand, crushed stone and geotextile, you will 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.

With independent sewerage, life in the country or in own home will not be intimidated by the lack of basic amenities. If you don’t have extra funds to purchase a ready-made sewer point, you can build a septic tank from Eurocubes with your own hands. It will not require special investments. Agree, this is a solid plus.

The information presented to you is based on personal experience independent builders of their own sewerage structures from European packaging. Requirements taken into account regulatory documentation. In order to facilitate the perception of information, attached step by step photos and helpful video tutorials.

Arrangement sewer system using Eurocubes is considered one of the most economical options among summer residents.

Moreover, correctly manufactured and of high quality installed septic tank able to effectively cope with the functions assigned to him.

All that remains is to rigidly connect all the containers together by welding them to the frame metal rods. It is important that the structure does not fall apart, otherwise all the pipes connecting the compartments to each other will break

Step #2 – installation and installation

When all work on installing pipes and sealing joints is completed, you can proceed to the next stage - installation.

The type of soil matters here - with clayey, mobile soils, it is important to compact the bottom as efficiently as possible by constructing a cushion of sand and gravel. A concrete screed should be made on top of it to ensure that the bottom does not deform under the weight of the filled flasks.

Must be taken into account when pouring concrete screed that the pit should have a stepped bottom, because each subsequent container is shifted 20 cm lower than the previous one

Then you have to lower the septic tank into the pit. It is advisable to anchor it to further secure it in place and protect it from floating. Now you need to connect the incoming and outgoing pipelines to the septic equipment.

The pipes are laid with a slope towards the septic tank of 2 cm per 1 m of length. Moreover, the outlet pipe with the purified liquid is laid at an angle to the filtration field. It is advisable to insulate a section of the pipeline laid above the depth of soil freezing in the region

The walls of the septic tank and the pipeline will need to be insulated. To do this, you can take polystyrene foam or other material. All that remains is to fill the cleaning equipment, assembled with your own hands, with water and cover everything with sand.

Between the walls of the pit and the septic tank, as well as on top, foam or other insulation must be carefully laid

At high level groundwater, the walls of the Eurocubes will have to be additionally protected by pouring concrete. To do this, reinforcement or boards are placed in the gap between the container and the pit wall and the concrete is carefully distributed. If you do everything consistently, not forgetting to fill the septic tank with water, then the walls will not deform.

To prevent squeezing out by heaving soils and damage to the hull, backfilling of the walls can only be done with sand, carefully compacting

Concrete top part pit or not depends on the area. Pipes protruding above the surface must be protected so that nothing unnecessary gets into the septic tank through them.

To perform ground-based post-treatment of wastewater treated in a septic tank, it is necessary to construct one of the following structures:

When arriving at a country house or dacha, you want to be in comfortable conditions. Modern life It is already very difficult to imagine without sewerage and water supply, so these communications are among the first to be carried into the house. A septic tank made from Eurocubes is a simple and affordable way How to arrange a sewage drainage system with your own hands on a private plot.

Design features

This septic tank design resembles a classic cesspool or drain hole, except that the effluent has the ability to penetrate into the ground. Ready-made containers for human waste are reliable and durable, they are easy to install and can last for a long time without cleaning. If you can't buy ready-made system, can be done homemade septic tank this type. For example, use several PVC barrels located on the same level, but then you will have to independently calculate the size and location of the ventilation hole.

Photo - principle of operation

Advantages use of septic tanks made of plastic eurocubes:

1. There is no possibility of contamination of groundwater with fecal residues;
2. The system also performs surface drainage, there is no need to additionally equip the drainage system for the yard;
3. This is a septic tank closed type, i.e., unpleasant odors will not penetrate outside;
4. You can install as many outlets as you like, their number may depend on the number of sanitary facilities in the house or other individual characteristics buildings;
5. There are no problems with pumping water. The process is quick and does not require the services of professional companies. This is an excellent option for a summer residence, because septic tanks made from Eurocubes require virtually no maintenance.

But the system has certain flaws:

1. The cleaning process is completed in 3 days - this is much longer than automated system. But on the other hand, cleaning is carried out by bacteria, which increases the safety of using the system;
2. Plastic is a very malleable and fragile material that quickly responds to pressure. If the size of the cup pit is incorrectly calculated or the soil is floating, the septic tank may become deformed, shift, or even crack.

Such septic tanks are classified by size (volume), number of outlets and the material from which they are made. PVC, rubber and other types of plastic can be used as raw materials. With the choice of the required volume and number of bends, everything is a little more complicated. Specialists calculate the amount of water consumption.

Photo - barrel as a cube

On average, one adult consumes up to 180 liters per day. Water is purified in 3 days, therefore:

180 * 3 = 540 liters requires cleaning within 3 days, if more than 1 person lives in a family, then 540 must be multiplied by the number of residents. For example, suppose there are two adults and one child in the house:

540 * 2 = 1080 liters and a child half the size - 540. In general, the septic tank should, by minimum standards, hold more than 1500 liters. Eurocubes are made with a volume of 1000 liters, therefore, for such a sewerage system you will need two cubes. The same applies to the number of taps. It is necessary to calculate how much sanitary equipment is used and, based on the number of pipes, cut the required number of holes for them in the cube. It is worth noting that initially the container is supplied with only one hole, which is necessary for proper operation - pumping out wastewater and sludge.

Video on the topic:

Installation

Initially, the site is marked out and a layout diagram of the septic tank is prepared. There are a number of requirements for choosing the location for its installation:

1. The minimum distance from the facade of the house is 6 meters, and if there is a basement, then the calculation starts from the basement. In this case, the device must be located at least 50 meters from a lake or other water source;
2. The ditch that is being prepared for installing a septic tank must mandatory be concreted. This will protect the entire system from earth pressure;
3. A crushed stone or sand cushion is laid at the bottom of the trench, which will protect the septic tank from being pushed to the surface of the earth during the spring thaw or rising groundwater. Its minimum size is 10 centimeters and another 10 cm of solution on top;
4. In cold areas, additional insulation is used. Most often, in addition to cement, the ditch is covered with clay.

The size of the trench should be 10 centimeters larger than the size of the cube, since the frame will still be poured and a small amount of earth will be filled in for shrinkage. The pit for Eurocubes is dug along with trenches for sewer pipes that will enter the septic tank. These actions must be carried out simultaneously, since the septic tank is installed in the ground with side inlet holes.

Photo – calculation

Owners of septic tanks made from Eurocubes should also have a diagram of the location of incoming sewer pipes ready. The installation rules for such systems indicate that the minimum distance between pipes is at least 30 centimeters. After preparing the installation site, the cubes for the well are processed.

Instructions and diagram on how to set up a septic tank from Eurocubes with your own hands without pumping out wastewater:

If you need to build a septic tank without concreting the pit ( budget option), then to install cubes it is recommended to use metal mesh or frame. It can be easily done at home by welding reinforcement rods together with small increments.

Photo – Eurocubes in a grid

This completes the production of the septic tank. The system is covered and masked. Periodically it is necessary to check the amount of sludge and remove it. You need to clean the septic tank at least once a year for irregular use and 2 times for constant use. In the first year, after 12 months, it is necessary to supplement the bacteriological filter with new aerobic microorganisms; subsequently, this is done once every 2 years.

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

Sewer structure made of Eurocubes

The cubes that we will use to make a septic tank are made in the form of containers made of polyethylene that is resistant to chemical compounds. Such material in contact with aggressive environment completely retains its mechanical and physical properties. The containers are placed in a welded frame made of metal profiles. The volume of Eurocubes varies - 640–1250 liters. The inside of the described containers is 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, thanks to the presence of steel profiles and an ergonomic cubic configuration, serious loads; resist environmental influences. Such containers are initially manufactured for long-term storage and transportation of aggressive substances. Therefore, they can be called ideal for the construction of autonomous ones.

A septic tank made from Eurocubes has a number of advantages:

• high speed of building the 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 work to prepare plastic containers for 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 ground. This can be avoided by attaching containers to concrete base tie straps and cables. Also, Eurocubes with thin walls can become deformed under the influence of increased loads. It is not recommended to use such containers for arranging a septic tank.

• perform thorough waterproofing of containers;
• wisely choose the location 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 containers together with steel rods;
• protect the cubes from strong compression (completely concrete the ditch for the country sewer system or make container lining from boards).

Such measures significantly increase the efficiency of operation and reduce all its “cons” to a minimum.

Country sewerage without pumping out wastewater - device diagram

By making a septic tank from Eurocubes with your own hands, you will have at your disposal a reliable and fairly environmentally friendly “mini-sewage system”. Its operation is based on the separation (mechanical) of large waste particles found in waste water Oh. This becomes possible thanks to the two-level design of the septic tank, which provides the so-called “overflow phenomenon.”

The operating diagram of the system looks like this:

1. From the plumbing equipment, wastewater flows through pipes into the first container. It separates heavy fractions, which sink to the bottom of a plastic container.
2. 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 flow of large particles is ensured by the fact that a certain height difference is provided between the containers.
3. By drainage pipe waste from the second container is discharged into the ground. The pipe, note, is mounted approximately 20 centimeters higher from the bottom of the container. A check valve must be installed at its end. It prevents the possibility of wastewater flowing back into the pipe.

Often special biological activators are added to Eurocubes. They form a special environment in containers 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 total number drains). Due to this, wastewater enters the ground, which environment does not cause any damage.

You can improve a cleaning system for your dacha that does not require waste pumping by constructing filtration fields in your suburban area or a drainage well. As we can see, to make a truly effective “ private sewer“It’s quite possible for a dacha.

Preparatory stage - taking into account all the little things

You will be able to build a high-quality sewer system 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. It is selected 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 a slope of the sewer pipe for each meter of at least 2 centimeters;
• it was possible to easily approach the containers to service them;
• the pipeline had no bends (if it is not possible to do without them, it is necessary to install intermediate wells).

In addition, it is worth understanding that excessive removal of the septic tank from a residential building will require you to spend considerable money on the construction of an extended pipeline. And the long length of the pipes contributes to the formation of blockages in them, which you will have to clear. Therefore, there is no need to build a septic tank without pumping 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 at the dacha 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 permanently, it is better to install larger containers. According to existing standards, one person consumes about 200 liters of water per day. It is recommended to install a septic tank three times larger in volume.

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

Let's get started - prepare the pit and containers

We will install plastic Eurocubes in the pit. It must have certain geometric dimensions. It’s easy to decide on them - add 15 cm in length to each side of the containers used. And you dig a pit for the obtained parameters. A gravel cushion should be made at its bottom. Then pour concrete mortar onto it (up to 0.3 m thick) and immediately install metal hinges into it. They will be needed to secure the containers.

At the stage earthworks trenches also need to be dug. You will lay sewer pipes in them. Please note that it is necessary to provide a slight slope of the trenches towards the installed wastewater collection and treatment system. Now you can start preparing the containers. We will need to make several holes in them for ventilation and pipes (inlet and outlet), and drains in 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 sections of pipes 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 a tee.

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

On the other side of the cube there is another hole - the exit hole. It should be somewhere 0.2 m below the first one. Make the same hole in the second container. Then connect them with a pipe - use tees. Ventilation outlets also need to be provided above them. After this, you need to weld the Eurocube bodies together (you can additionally use reinforcing bars). Due to this, the containers will not move in relation to one another. And then you need to seal the necks of the cubes, fasten them (as firmly as possible) with rivets and coat them with sealant.

Installing a septic tank - sequential assembly

After the concrete in the pit has dried, we lower the Eurocubes into it (don’t 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 in the area is unstable and there is a possibility of flooding, line the containers with boards or sheet metal. Filling is also allowed concrete mortar gap between the ground and the walls of the cubes to increase their stability.

But concrete should only be poured after you have filled the containers with water. Next important stage works – insulation of Eurocubes. This operation must be carried out necessarily, otherwise aerobic bacteria will not be able to decompose wastewater when low temperatures. Insulation of containers is most often carried out with polystyrene foam boards or pieces of polystyrene foam.

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