Septic tank from Eurocubes with high groundwater. DIY septic tank from Eurocube

If you are just starting to live in a private house, then you will probably be faced with the question of which sewer system to use in a particular case. The best option There will be a system that will be inexpensive and will allow the work to be completed fairly quickly. Special designs - septic tanks - are quite expensive and require careful maintenance. A rather labor-intensive and expensive option is cesspool from concrete rings. In addition, the system will require pumping as well as twice a year.

Pumping involves calling a vacuum cleaner and costs money. One of the main disadvantages here is the unpleasant smell. The most profitable solution in this situation would be to use plastic containers, which will form the basis of the septic tank. You can use used containers to construct the system, because they are cheaper. At the first stage, the master will have to calculate the volume of the system, and then correctly install the structure. Only then will the septic tank work without interruption. Private homeowners in Lately Eurocubes are used for this. And you too can follow their example.

What are Eurocubes?

These are containers made of thick polyethylene, the outside of which is protected by steel mesh, ensuring reliability and durability. You can hold about 1000 liters of liquid inside. The cube can be used for reusable storage and transportation of various substances, among which food and water should be highlighted.

Containers are often purchased to store water so that you can later use it to irrigate your planted crops. This cube is perfect for sewer construction. Its advantages are:

maximum tightness;
quick installation;
the ability to carry out installation work independently;
construction speed;
easy container care.

A septic tank made from Eurocubes can withstand heavy loads, it is resistant to aggressive substances and has a low cost. If you want to save even more, you should purchase a used Eurocube. There is no need to carry out complex preparatory work before installing it. In addition, the system itself is quite easy to operate.

Why some consumers refuse Eurocubes: reviews

Such containers, according to consumers, also have their drawbacks; they are expressed in the lightness of the material. This factor ensures that if the area is flooded, the container is pushed out. In addition, the products, according to buyers, have rather thin walls, which sometimes cannot cope with the load, so they become deformed.

Preparation

Before leaving the European Cup, you must make preparations. To do this, select a location for installation, which can be located anywhere on the site, because a sewer truck is not needed. There is no need to empty the system. It is important to determine the type of soil before starting work. This is done because some soils are not suitable for installing such structures. If the soil is just like this, then the bottom will need to be further strengthened, as well as the walls of the recess for installing the system.

The initial stage of work should be accompanied by determination of the groundwater level. To do this, in the spring, using a drill, a well is dug to a depth of 2 m. After a day, its walls should be checked. If the groundwater is deep enough, the walls will remain dry. Their humidity indicates a high groundwater level. The level can be measured at the nearest well.

A septic tank made from Eurocubes must have a volume, which should be calculated at the initial stage. For this, the following formula is used: V = (N x 180 × 3) : 1000. In it, V is the volume of the installation, and the number of people is indicated by the letter N. Due to the fact that the consumption rate per person reaches 180 liters per day, liters should be multiplied by the number of residents and by three days. During this time, the system will purify the water.

The resulting number should be divided by 1000 to obtain the volume of the container in cubic meters. It is necessary to purchase a cube of a larger volume than required, because installing a septic tank with insufficient volume is prohibited. As practice shows, for a family of 3 people, 2 containers, each with a volume of 800 liters, will be sufficient.

When excavating, it is better to use special equipment. However, if this is not possible, you can get by with a shovel. During the work, a trench is prepared that will go from the sewer outlet to the septic tank itself. The external pipeline pipe must be located with a certain slope, which will allow the drains to move under the influence of gravity.

The slope must be correct, otherwise blockages may form in the pipe. The slope of the pipe will depend on its diameter. For external pipeline autonomous sewerage for a dacha or at home, you should use a pipe with a diameter of 110 mm. In this case, the slope reaches 2 cm per meter. If the septic tank is 7 m away from the house, then the difference in level from the beginning to the end of the pipeline is 14 cm.

When making a pit for a septic tank from Eurocubes, it is recommended to first consider the photo. Perhaps they will allow you to avoid mistakes. The size of the pit should be such that after installation is completed, the gap between the container and the walls is 20 cm or more. This is necessary for easier installation of the system. It is also important to take care of strengthening and protecting the outer walls, because plastic can become deformed under the influence of soil.

Sand or soil can be poured into the bottom of the pit. Given the depth of the hole, the height of the cushion must be taken into account. After this, a screed of concrete mortar is poured onto the bottom, and metal embedded parts are installed. The latter are necessary for attaching Eurocubes.

The internal walls of a pit for a septic tank made from Eurocubes, reviews of which will allow you to make right choice, are also strengthening. This is done by installing sheets of metal, but it is better to build formwork and pour the walls concrete mortar. If you neglect these recommendations, the septic tank may be moved from its place during the process of soil movement, which will cause destruction of the entire system.

Price issue

For a septic tank made from Eurocubes, you can take two plastic containers, the volume of each of which will be equal to 800 liters. The cost of the products is 2000 rubles. If required, the volume of the Eurocube can be increased to 1000 liters. If everything is done correctly, the system will work properly both in summer and winter, without causing problems with operation.

However, it will be necessary to regularly add bacteria to prevent the occurrence of unpleasant odors. Many users today purchase Doctor Robik, which is an American drug. You may prefer "Tamir".

Installation steps

Excavation work involves preparing a ditch. Once the volume of the system has been calculated and you know the size of the septic tank, you can start digging. Concrete is poured at the bottom or a cushion of crushed stone and sand is laid. This is necessary so that light cubes do not get pushed to the surface in the spring when the time comes for flooding and floods.

The walls of the septic tank are also strengthened; slate should be used for this. You can simply fill the perimeter with sand. The bottom layer of concrete or sand should be 20 cm or more thick. On the sides, space should be left for a layer of sand and laying a thermal insulation layer.

If you are faced with the question of how to do it, then you must seal the drain hole. On the sides of each container it is necessary to do round holes for installing pipes. The diameter of the holes can vary from 20 to 30 cm. A hole should be made in the upper part of the container for a pipe that will act as ventilation.

The pipe is connected to a tee, which, in turn, must be connected to each inlet and outlet. This will allow you to get a container with a pipe, which is connected inside each of the tanks with a tee.

Work methodology

The craftsman will have to make holes for connection. In the first container, the hole is located 15 cm below the sewer hole. The difference in height should be used. The next container is installed 15 or 25 cm lower than the first. These containers are interconnected polypropylene device fixed with reinforcement or wire. In the second container, 30 cm from the top side, you need to make a hole for the drainage pipe. The seams are well sealed with sealant.

Thermal insulation and fastening

Before you make a septic tank from Eurocubes with your own hands, you should think about the need to insulate the system. The device itself is installed on a concrete pad, and it should be covered with foam on all sides. If it is not available, then you can use foamed polystyrene.

Afterwards the container is filled with water and poured concrete on the sides. Instead of the latter, you can use sand. The top of the structure is covered with polystyrene foam and sprinkled with soil. Only ventilation cleaning pipes are left on the surface.

When making a septic tank from Eurocubes with your own hands, it is recommended to first examine the photo. During operation, it is important to prevent the system from being completely filled with waste, because the container may burst from internal pressure. In order to eliminate cracks, it is necessary to perform drain tank, which will be located below the freezing point. An alternative solution would be high-quality aseptic thermal insulation.

The tanks must be connected to ventilation pipes that are located nearby. If this solution does not suit you, then the system can be equipped with self-ventilation. When installing a septic tank from a Eurocube for a private house, you will need to additionally install a valve, which is necessary for air suction. This is required to ensure that rarefied air does not remain in the sewer pipe, which could interfere with the drainage of wastewater into the tanks. Fecal wastewater is separated using the same solution, which increases the residence time of the wastewater in the tank. In addition, this helps to eliminate the influence of household antiseptics on the first tank where fecal waste ends up.

System with pumping

A septic tank made from Eurocubes with pumping assumes a system that does not have drainage fields. The latter are required for wastewater treatment at the final stage. The design of the drainage system can only be constructed if the site has soil with suitable characteristics. The soil must have the ability to treat runoff through a sand and gravel filter. The purified liquid will go into the ground, and then undergo additional soil purification.

Septic tank maintenance

Even if you do not clean the containers of sewage from Eurocubes with your own hands without pumping, once a year they will still have to be freed from accumulated sludge. This is best done in the fall, when bacterial activity is reduced. To do this, you should clear the area in which the cleaning ventilation pipe is located, using available means. Through this pipe you should get unprocessed products that can be used as fertilizer.

For reference

When installing a septic tank, it is especially important to ensure complete tightness of the drainage point from the tank. To do this, unscrew the cap and lubricate the threads with sealant, and then replace the cap. When installing a septic tank from a Eurocube at your dacha with your own hands, you must take into account that the size of the neck of the container does not allow you to insert a tee inside.

Conclusion

In order to widen the holes, you should use a grinder, with which a hole is temporarily cut in place of the neck. After the tees are installed, the holes are sealed with rivets and sealed well. A septic tank for a dacha made from Eurocubes must be installed in such a way as to eliminate the possibility of the containers moving relative to each other. To do this, the metal frames of the container are welded together. For this you need to use a metal rod.

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. The requirements of regulatory documentation are taken into account. To make the information easier to understand, step-by-step photos and useful video tutorials are included.

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

Moreover, a properly manufactured and high-quality installed septic tank is able to effectively cope with the functions assigned to it.

All that remains is to firmly connect all the containers to each other by welding metal rods to the frame. 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 begin 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

If the groundwater level is high, the walls of the Eurocubes will have to be further 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:

How to properly and effectively organize sewerage on summer cottage do it yourself, a question that often arises among people who are deprived of the opportunity to use the centralized option. And really the need for autonomous, and most importantly effective system drainage of sewage and waste is simply necessary for the comfortable existence of a modern person in a private wooden house.

And although the idea is firmly ingrained in our minds that only a cesspool is the way out of the current situation, this is far from the case. Nowadays, septic tanks (a cesspool with several chambers for cleaning, see do-it-yourself septic tank) are becoming more and more widespread, due to a more sophisticated sewage filtration system and excellent productive capacity.

As a basis for wastewater, there are many various materials. Let's consider one of the simplest and most effective of them - a do-it-yourself septic tank made from Eurocubes.

Memo: Eurocube is a container for transporting large volumes of liquid.

It turns out that we remove the pipe from the house at a depth of 50 cm, until sewer pipes will reach the septic tank, the depth will be approximately 56-62 cm, we will insulate the pipes (with foam plastic or mineral wool— somehow I don’t feel like digging into the frozen soil in winter), then the septic tank itself and the absorption field/drainage well. We anchor the septic tank itself so that it does not float up in the spring with the rise of groundwater, we strengthen/insulate the walls so that the soil does not squeeze the septic tank. It turns out that from the surface to the top of the septic tank is about a meter. We insulate the septic tank from above and fill it with crushed stone/earth.

drawing/diagram of a septic tank made from Eurocubes

Even a person with little knowledge of construction will be able to make a septic tank from a Eurocube with his own hands; it is enough to know a few basic rules.

The advantages of the Eurocube compared to other options for constructing a septic tank are undeniable:

Its price is quite low compared to similar designs (plastic septic tanks).
The time required to install such a septic tank will not exceed 2-3 days, provided that you perform all the main work alone.
The plastic from which the Eurocube is made is durable and has excellent waterproofing.
Such a septic tank requires a minimum of additional work; there is no need to cover it and additional finishing, unlike a septic tank made of concrete rings.

Let's get started

As in any other business, from the beginning we need to decide what goals and results we set for ourselves. Having made the necessary calculations about the average daily volume of wastewater that the septic tank has to cope with, proceed to search for the necessary cubes. Remember, the total volume of septic tank tanks must be at least three times the daily waste.

Tip: it is preferable to have no more than two drainage containers, this will reduce the total number of connections between the chambers, but will not affect the efficiency at all.

Next, armed with a shovel (or hiring the necessary equipment) let's start digging a pit with our own hands. Due to the fact that the Eurocube is sealed and additional drainage system, the location of such a septic tank can be in any convenient place.

From excavator to designer.

Having prepared the pit for the future sewerage system, we proceed to the actual installation DIY septic tank from Eurocubes. To do this, you should make a cushion of sand or crushed stone at the bottom of the pit. Well, if there is a risk of soil subsidence under the weight of the filled cube (and, accordingly, the risk of damage to the connecting pipes), it is worth making a concrete screed.

Note: upon completion of installation, you need to make sure that all pipe connections are tight. As additional insulation, it is worth using a special sealant or liquid rubber.

This is what an almost finished septic tank looks like

The sewerage and filtration scheme of such a septic tank itself comes down to the following. Through the pipes, the wastewater enters the first section of the septic tank, where heavy particles are separated and settle to the bottom of the tank. Then, when a certain level of waste is reached (approximately 50 cm), sewage through the connecting pipe enters the second chamber of the septic tank. As an option, you can use a height difference (the second Eurocube is installed lower by 20-30cm).

The second camera is equipped with a special drainage pipe(it is possible to use several pipes), which is located at a level of 15-20 cm from the bottom of the cube. To improve drainage capacity, it is advisable to additionally build a drainage well or filtration field.

Both chambers are required to be equipped with a ventilation pipe protruding a couple of meters above the ground. In the interior of the first chamber, the ventilation pipe should be located 10-15 cm above the connecting pipe, and not only serves as a removal of harmful fumes, but also serves to pump out sewage with a sewage machine.

Advice: do better ventilation pipe of several elements so that, if necessary, the upper part can be detached and used for pumping out waste.

In the second chamber, the ventilation pipe should also be located at a level of 10-15 cm, but already from the drainage pipes.

After preparing and checking all connecting elements, the Eurocubes take their designated place in the pit and are again, this time, thoroughly fixed with pipes.

At high groundwater levels

Alpine slide - filtration field

If the level groundwater is high, then you have to do it embankment field filtration - it can be designed in the form of an alpine slide :).

So, if the ground level is high, the septic tank is installed as usual, but here you will have to carefully secure the Eurocubes to the bottom of the pit, as if the ground level is high, they can float up and damage the tightness of the connections. Then you will need another container (you can install a third Eurocube as an additional filter block or well). A pump with a float switch is installed in the third compartment, which will pump water into the filter field that we made above groundwater.

Completion of work on installing a septic tank from Eurocubes.

A septic tank made from Eurocubes crushed the soil

The final stage is the formation around external wall concrete screed to protect the cube from soil pressure on it. If the soil is quite loose, you can get by by simply compacting sand around the cubes or installing OSP panels/slate/corrugated sheets.

At this point, the process of creating an autonomous sewer system can be considered complete.

For drainage, you should use special perforated pipes sprinkled with coarse crushed stone. Crushed stone will prevent pipes from silting and at the same time has excellent throughput.

If possible, try to use additional funds wastewater disposal, for example: a filter well or special biological mixtures.

Plastic is very sensitive to low temperatures, therefore you should not allow it to be completely filled in the winter; in severe frost it can simply crack from internal pressure. One way to avoid this problem is to build a septic tank below the freezing level of the soil or by additionally insulating it.

To make the Eurocube more stable from the impact of soil, you can make its outer sheathing with rocky wire.

For those who live in the private sector, one way or another the question will arise: how to install a local sewer system and what to make a storage tank for wastewater from. There are many septic tanks on the construction market.

However, they do not always have the required dimensions. The construction of a septic tank with reinforced concrete rings requires large material costs during the period of purchase and installation, as well as long-term service - pumping out wastewater, cleaning the well. One of economical options treatment plant is the installation of a septic tank from European Cups.

What are the European Cups?

Eurocube, like a septic tank made from Eurocubes, as such is not intended for sewerage purposes. This sealed plastic tank and its purpose is to store liquids, as well as transport technical liquids, with a volume of 800 to 1000 liters.

Thanks to the reinforcing belt made of metal mesh welded from galvanized steel, in which the Eurocube is placed, it has high mechanical resistance to various loads. Used containers are quite cheap. The price of one cylinder, depending on the offer, can be from 1 to 3 thousand rubles.

If you install Eurocubes according to the instructions and provide normal care, then such a local sewage system will last quite a long time.

Helpful information! But before you start installing a septic tank with your own hands, you need to determine its required volume. If we take into account the average statistical data that per person the rate of water consumption per day is equal to two hundred liters of water, and it will take 3 days to process wastewater, then the capacity for a family of 3 people should be approximately 2 cubic meters. If you have a significant water consumption or many people live in the house, it is recommended to use 3 - 4 containers.

Preparing European cups for assembly

In order for a homemade septic tank made from Eurocubes to be a full-fledged sewer drainage device, it is necessary to install pipes on it - inlet and outlet. After this, the Eurocubes are installed in the prepared pit. Since the Eurocube is very light and thin-walled, the structure will need to be reinforced with concrete to protect it from soil pressure. The hole will need to be dug wider than eurocube 25 cm from all sides.

First, the concrete solution is poured into the bottom of the well,
Next, install the cubes
Pour the solution on the sides.

Helpful information! It is recommended to cover the side parts of the Eurocubes with foam plastic before pouring for additional thermal insulation. In addition, it is necessary to fill the container completely with water to avoid breaking the walls of the material while working with the concrete solution.

A septic tank made from Eurocubes is a preliminary stage in the construction of a sewer system. According to the technology for treating wastewater and further discharging it into aeration fields, it will be necessary to lay trench for the drainage system. The length of the ditch from the septic tank should be about 20 m, and the depth - depending on the type of soil, but not less than half a meter.

Assembly of the drain structure

First of all, the cylinder drains are sealed.
If the neck of the container is small to accommodate the tee, then it is cut.
On the sides of both Eurocubes, holes are made for the incoming pipe, at a distance of 20-30 cm from the top.
Holes are cut out on the horizontal plane of the Eurocubes to install ventilation.
All pipe connections are made using tees.

Helpful information! To connect the drain cylinders to each other, a circle is cut out in one of them 20 cm below the hole for installing the sewer pipe.

Each subsequent container should be located 20cm lower than the previous one. Eurocubes are connected with a pipe and the entire structure is firmly mounted with a metal clamp, welding it to the reinforcing mesh of the cubes. A hole is made in the second cube to install a pipe under the drainage system at a distance of 30 cm from the top. All connections are sealed or sealed with silicone.

After the installation is completed, the septic tank made from Eurocubes is lined with foam plastic and covered with earth on top.
Pipes adapted for ventilation remain outside.
After this, it is necessary to remove the drainage pipe from the septic tank. For drainage purposes, it is best to purchase a perforated pipe with a diameter of 50 mm. It is connected to the second tank of the septic tank and is led along an aeration trench.
For proper aeration, gravel is first poured into the trench in a layer of 20 cm.
The top of the pipe is filled with gravel and then with soil.

If the groundwater level is significant, a bulk drainage field is installed . In this case, drain containers are installed following the instructions given above. But here you will have to put another container. It can be installed as an additional well. A pump equipped with float switch. With its help, treated wastewater will be pumped into a drainage field that was filled above the groundwater surface.

You should not allow the septic tank to completely fill with wastewater in the winter, taking into account in this case that the plastic has the ability to explode due to internal pressure. The best way to avoid an accident is to mount the drain tank below the freezing point of the soil or to insulate it well.

Helpful information! When installing a sewer flushing system, a fan extractor or a valve that facilitates the suction of atmosphere should be installed. This is necessary to ensure that rarefied air does not form in the sewer pipe, which can interfere with the drainage of wastewater into drain tanks.

It is more advisable to break up fecal and clean wastewater - using this method, it is possible to continue the period of residence of sewage water in the cube to eliminate the impact of household antiseptics on the first tank (into which fecal waste is drained).

The principle of sewer cleaning

The operating principle of a septic tank made from Eurocubes is carried out according to the rule of mechanical separation of large fractions that enter the wastewater and further disposal by anaerobic digestion. The first stage of purification is provided through a two-level drain tank device, when wastewater flows from one tank to another. Anaerobic digestion occurs with the help of bacteria that create a bacterial environment in the septic tank. To begin this process, bioactivators will have to be added to the septic tank.

Insoluble particles and suspensions settling to the bottom of the container will amount to about 0.5% of the total volume of sewage. The purified water that enters the soil will not be suitable for consumption, but it will no longer cause any harm to the environment. The containers will need to be cleaned of accumulated sludge in about a year.

It is recommended to do it in the fall, when the activity of microbes inside the treatment plant weakens. To do this, a hole (hatch) must be provided through which waste that is not processed by microorganisms, which zealous owners use as fertilizer, is removed using improvised means.

A very visual video illustrating the entire process of preparing Eurocubes and constructing a septic tank from them:

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, when 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 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 steel profiles and 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 construction autonomous septic tank for the dacha.

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 securing the containers to the concrete base with 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 for 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 under country sewerage or make container lining from boards).

Such measures significantly increase the efficiency of the sewerage system for country house 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 present in wastewater. 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:

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.
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.
The drainage pipe carries waste from the second container 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 the total amount of waste). Due to this, wastewater enters the ground, which does not cause any damage to the environment.

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 you can see, it is quite possible to make a truly effective “private sewerage system” 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, and also purchase all 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 excavation stage it is also necessary to dig trenches. 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 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 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, a sewer pipe will be connected to the hole. It will connect the internal system and the septic tank together. 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 between individual elements of the system! Above the tee it is necessary to provide vent. 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. It is also allowed to fill the gap between the ground and the walls of the cubes with concrete mortar 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 at low temperatures. Insulation of containers is most often carried out polystyrene foam boards or pieces of foam plastic.

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 is ready!

What are Eurocubes?

Eurocubes are cubic containers made of plastic and placed in a frame in the form metal mesh made of galvanized steel. The most common volume of such containers is 1 m3.

The primary purpose of these tanks is to transport various liquids, including technical purpose: sodium hypochlorite, acids, alkalis, water, etc. In addition, such plastic containers are used again for various purposes, for example, for constructing septic tanks. It's connected with positive properties ecrocubes.

Advantages and disadvantages

Cubic plastic tanks – An excellent option for arranging local sewerage due to a number of characteristics:

light weight, which facilitates simple installation without the use of special equipment;
low price;
the possibility of using used products, which further reduces the cost of the finished structure;
resistance of the walls of the Eurocube to the effects of aggressive environments, which is especially important when arranging sewage systems;
speed of preparation of the tank for installation;
the presence of a metal frame, which reduces soil pressure and is durable, as it is made of galvanized steel;
the tightness of the container;
ease of operation and maintenance.

But when choosing such tanks for constructing a septic tank, it is necessary to take into account their disadvantages.

Due to the lightness of plastic, the container can float under the influence of groundwater. To avoid this, you need to prepare a concrete base to which to attach the Eurocube.
The metal frame does not always cope with soil pressure, which ultimately leads to deformation of the container. To prevent this, fill the space between the containers and the walls of the pit with concrete.

Otherwise the septic tank is simple device and the principle of operation copes with its task quite effectively.

How does a septic tank made from Eurocubes work and work?

To set up a wastewater treatment system, 2 containers are used, connected to each other by an overflow system.

What should you consider during installation?

Both during preparatory activities and during the actual installation of such cleaning device Several general and specific rules must be followed.

Any local waste disposal station must be located on site in accordance with regulations. The distance from the house to the septic tank must be at least 5 m, from drinking underground sources - 50 m, from surface waters– 30 m, from trees and bushes – 3 m.
In addition to sanitary standards, it is also necessary to take into account the possibility of a sewage truck approaching the station to pump out the resulting sludge.
When building a cesspool, care must be taken to install a ventilation riser.
It is better to install containers on a concrete base, which has metal eyes for securing the containers with cables. This will save the septic tank from floating.
When preparing a pit and trenches for pipes, the freezing point of the soil must be taken into account. Pipelines and their inlets must pass below this mark.
It is recommended to additionally insulate the containers.
When choosing tanks, you need to take into account that the tanks should not be as full as possible, otherwise cracks may appear in the walls under pressure.

In connection with the last factor, it is important to correctly calculate the volume of the septic tank.

Calculation of the volume of tanks for a cesspool

Eurocubes are standardly produced in a volume of 1000 liters, but there are containers of 800 and 1200 liters.

To decide which tanks are right for you, you need to make standard calculations.

The required daily capacity can be determined by multiplying 200 liters by the number of residents.
To calculate the required volume of chambers, the resulting productivity value must be multiplied by 3, because on average the wastewater is in the septic tank for three days.
It is recommended to increase the volume by 10-20% to take into account the possible arrival of guests.

This is what calculations of the size of a septic tank look like for a house that does not have sanitary equipment that produces large volumes of wastewater: bathtubs, dishwashers, etc. washing machine. But in practice, for a family of three people, two tanks of 0.8 m3 each are usually sufficient.

After making the calculations, you can begin purchasing materials and equipment.

What will be needed to install a sewer system?

In addition to Eurocubes, to install the system you need to buy other material, as well as prepare tools.

Plastic sewer pipes with a diameter of 100-110 mm for supplying wastewater to the septic tank and connecting the treatment stages, as well as the ventilation riser.
Fittings for plastic pipes.
Cement, sand, gravel for preparing concrete.
Sand for filling the bottom of trenches
Tools for cutting pipes.
Sealant for processing joints.
Insulation for wells, and, if necessary, for pipes.
Fittings for connecting cubes.
Waterproofing.

You will also need materials for soil treatment equipment. The set will depend on which filtration stage option you choose.

How to make a septic tank from Eurocubes with your own hands: step-by-step installation instructions

Having chosen a place to install a septic tank and purchased materials and tools, you can begin the installation process.

Excavation

First you need to prepare trenches for pipes and a pit for Eurocubes. The pit should be approximately 30-40 cm larger in width and length than the dimensions of the tanks. When deepening, it is necessary to take into account the concrete base and insulation layer, as well as the zero temperature point.

After digging the pit, the bottom is leveled and filled with concrete. The concrete layer must also be smooth. At the same stage, it is necessary to install metal loops for attaching containers.

While the concrete base is drying, you can start preparing the Eurocubes for installation.

Modification of tanks

Before installation, the tanks are connected together using fittings welded to metal frames. But first they prepare the cubes differently.

Additionally, the factory drain holes of the tanks are covered with sealant.
Holes for inlet and outlet pipes are made in the side walls of each container, maintaining a slope. This means that each subsequent hole along the drainage path must be lower than the previous one. Here you need to take into account that the second container will be installed 0.2 m deeper than the first, which will allow for better use of its volume.
A tee must be placed in each tank. If the fitting does not fit into the factory neck of the cube, then it must be temporarily enlarged. As a result, an inlet pipe will need to be connected to one hole of the tee. From the opposite opening of the fitting, the drains will drain into the compartment, and the third should be directed to the upper edge of the container to connect to the ventilation riser.
The pipes are connected to the tee and to the Eurocubes, and a pipe is installed for the outlet pipe going to the soil treatment.
Treat the joints with sealant.
The upper hole, which was used to insert the tee, is restored and sealed with sealant.

Now you can strengthen the connection of the tanks to each other using reinforcement. The containers are ready for installation.

Direct installation

After graduation preparatory work begin installing tanks and laying pipes.

The septic tank is carefully lowered to the bottom of the pit.
The tanks are secured to the concrete base using slings.
Place pipes in trenches, checking the slope.
The pipelines are connected to the septic tank and a ventilation riser is installed.
Cover the containers on all sides with insulation, for example, sheets of polystyrene foam.
Fill the compartments with water.
Gradually and carefully fill the space between the septic tank and the walls of the pit with concrete.
The pipes and septic tank are covered from above.

It will also be necessary to equip a soil filtration stage at the installation stage, and add biological products to the septic tank. The wastewater disposal system is ready for operation.

Tank Maintenance

The wastewater treatment station does not require frequent calls to the sewer truck, but once a year it is necessary to pump out sediment from the tanks, the level of which can be checked using a wooden stick.

It is also necessary to periodically add microorganism preparations. Especially if there is a smell around the septic tank.

Otherwise, this inexpensive design does not require any care.

Characteristics of Eurocubes

Eurocube is a convenient container for transporting and storing various liquids. It is made from plastic, which is chemical resistant, non-toxic and durable. The surface of the cubes is covered with a grid of steel pipes, and in the lower part there is a metal or wooden pallet. At the top of the container there is a 15 cm neck, screwed on with a polyethylene lid. A ventilation valve is installed on the lid. The cost of used containers is low (on average 1-3 thousand rubles).

Due to the thickness of the walls, the Eurocube is resistant to high loads (depending on its capacity). Additional strength of the tank is provided by the outer frame made of steel wire. The liquid is drained into a hole with a neck, which is closed with a lid.

To protect against abrasion, corner shields are placed in polyethylene tanks. The volume of the containers is 640-1250 l, weight up to 67 kg.

As a material for the production of treatment plants, Eurocube has the following advantages:

tightness, protection against wastewater entering the soil;
resistance to high loads, ensured by steel construction and ergonomic shape;
efficiency of construction of treatment plants;
ease of installation and maintenance;
low cost of tanks;
minimal preparatory work;
efficient operation, easy care and use.

The disadvantages of a septic tank made from Eurocubes are:

containers with thin walls can be deformed under high loads;
Due to the light weight of the material, flood waters can push out the treatment plant, so it must be secured to the concrete base with tie-down belts or cables.

To prevent damage to the Eurocube, you should correctly place it on the site in accordance with the topography, carry out waterproofing work, concrete the pit or make wooden cladding (from compression), connect the tanks with reinforcement. Carrying out such activities will minimize the existing disadvantages of a septic tank made from Eurocubes.

The principle of operation of the installation and the rules for its placement

Sewage tanks are installed at a distance of at least 2 m from the building. Access should be provided for cleaning tanks. The depth of placement of the cubes depends on the size of the sewer pipe, because for each meter a slope of 1 cm deep is required (so that feces do not move in the opposite direction).

The operation of the treatment plant is based on the principle of mechanical rejection of large-sized fractions from wastewater. After this, they are decomposed by bacteria. The volume of insoluble fraction is about 0.5% of the wastewater volume.

The design of a septic tank made from Eurocubes often includes two tanks connected in series. To fully utilize the volume of the second tank, it should be placed below the first.

The procedure for filtering and draining a septic tank is simple. Through pipelines, wastewater enters the first section of the installation. Heavy particles settle in the compartment and remain at the bottom. When the waste reaches a certain volume, the waste slowly flows from one container to another. To do this, they often use a height difference or install a drain pipe at a certain height. In the second compartment of the septic tank there is a drainage pipe located at a distance of 15-20 cm from the bottom of the tank. In the second container, the liquid is purified using bacteria, which are added in concentrated form. Microorganisms carry out additional purification of water, which is directed into the soil through a drainage pipeline located 15-20 cm from the bottom of the installation.

To improve the purification system, you can additionally build a well or filtration field. All septic tanks must be equipped with ventilation pipes. They are located above the soil surface at a height of 2 m. In the first tank, the ventilation pipe is placed 10-15 cm from the installation plane of the containers and is designed to remove fumes.

To install a septic tank from Eurocubes with your own hands without pumping, you should familiarize yourself with the sanitary and building regulations its location on the site.

Rules and regulations for the placement of a treatment plant:

Regardless of the chosen design, the installation depth of the device should not be below ground freezing. Otherwise, the septic tank needs to be insulated;
if the area is small, an aeration well should be installed for ground filtration;
The soil should be highly permeable (gravel or sand). On clay soils, only a pump and cesspools can be installed.

In order for the sewer system to function, it is necessary to calculate the approximate volume of wastewater. In accordance with SNiP 2.04.03-85, the daily norm of liquids consumed for one resident is 150-200 liters. This indicator is multiplied by the number of people living in the house, again by 3 (in approximately these days the water in the septic tank is purified). High-quality cleaning carried out within 72 hours. To calculate the volume of the container, the resulting amount is divided by 1000.

For example, 3 people permanently live in a house, which means the daily volume of wastewater will be 600 liters. In this case, a septic tank with a total volume of about 1800 liters is built.

The septic tank scheme is available to both professionals and ordinary people who wanted to create an autonomous sewer system in their home.

Carrying out preparatory work

First you need to decide on your goals and results. Having made the necessary calculations on the average daily volume of wastewater that the septic tank will process, you should select the optimal capacity. It should be remembered that the total volume of the tanks should be 3 times the daily flow.

To assemble a septic tank from Eurocubes, you need to prepare certain tools and materials. The materials you will need are insulation, sealant, a couple of Eurocubes, boards, waste and overflow pipes for supply, cuffs, several pipes, tees, cement (for concrete screed), sand, gravel and pipelines for drainage.

You should also prepare a shovel or special equipment for digging a pit, an angle grinder for cutting holes and trimming pipelines.

Basic work on the manufacture and installation of a septic tank

During installation work for sewage systems made from Eurocubes, compliance with standards and phased implementation of measures is required.

Work with the earth. Before the construction of the treatment plant, trenches are prepared for laying pipelines, as well as a pit for the location of tanks. The parameters of the pit must correspond to the volume of the chambers with 15 cm added on each side. Depending on the height of the containers and the slope from the sewer system, the depth is selected. The bottom of the pit is covered with a gravel cushion, a concrete solution is poured in a layer of 20-30 cm, where fastening loops for containers are mounted.
Assembly of the structure. The septic tank is connected from two Eurocubes. Tees are installed in the necks of each container or a technological cut is made around them, which is then sealed. On the sides of the tanks, openings are made for the outlet pipeline, and a ventilation and cleaning pipe is cut in. A hole is made in the first container for supplying a sewer pipe connecting the installation with internal system. When connecting elements, the sealing of the joints should be checked. An outlet ventilation hole is made in the container above the tee, into which a 50 mm pipe is inserted. An outlet hole is made from another part of the container at a level below the first. You also need to make a hole in the other tank, taking into account that both containers will move between each other by 20 cm. Tees are attached to the pipeline connecting both cubes, and ventilation outlets are attached to the upper part. All connections are sealed, the technological cut is sealed, it is fastened with rivets and treated with a sealing compound. Waterproofing material is laid on top. To prevent the containers from moving, the frames should be welded. Strong fixation of the cubes is ensured by reinforcement.
Installation of a septic tank. Such work may vary. If the groundwater is high, a reinforced concrete slab or concrete pad is placed on the excavated bottom. When the water level is low, a sand cushion is poured, leveled and compacted. Assembled structure lowered into the finished pit, connect the pipeline from internal sewerage buildings and a pipe from a well (or drainage field). The check valve is installed on the outlet pipe. The cubes are attached to the hinges with a cable. On heaving soils, plastic containers are protected from deformation by lining them with boards or sheet materials. When installing a septic tank made from Eurocubes, made by yourself (its design can be seen in the photo), you can fill it with concrete mortar between the walls of the containers. In this case, water is poured into the cube tank and it is gradually smoothly concreted.
Insulation work... To ensure effective decomposition of wastewater aerobic bacteria, containers must be kept at high temperatures. The connected containers are insulated with sheet plastic (expanded polystyrene or foam). After completion of the insulation and installation work, sheet insulation is laid on the septic tank and soil is poured. Only pipelines for ventilation and cleaning should remain on top. The septic tank needs periodic cleaning of the sewerage using waste recycling. A compressor must be installed that is connected to the electrical network. Wastewater is processed by aerobic bacteria, after which the water can be used for irrigation.
Laying drainage pipelines. Drainage pipelines are perforated pipes with a diameter of 50 mm. They can be routed from the outlet pipe of the second tank along the filtration field. To better distribute water through the pipes, they are sprinkled with a gravel layer of no more than 20 cm.

Septic tank maintenance without pumping

To keep the septic tank system in operation long time, she needs to be looked after. Oil decay products, cigarette butts, construction garbage, medicines and solvents. Overfilling and accumulation of large volumes of waste should be avoided.

When using the sewer system seasonally, it is better to preserve it. This will protect the septic tank and pipes from rupture and freezing.

The second tank should be regularly filled with biological products. Do not overuse detergents, as they have a detrimental effect on microorganisms.

Once a year, the septic tank should be cleaned of accumulated sludge. It is better to carry out such work in the autumn when bacterial activity is reduced. Next, the area where the cleaning and ventilation pipe is located is cleared and unprocessed products are removed through it using improvised means. They can be used as fertilizer.

If the pipes have longer length, that is, the likelihood of blockages. Then you need to create inspection wells.

The use of an autonomous sewer system will reduce construction costs and ensure comfortable living in the house.

Features of arranging a homemade septic tank

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

Moreover, a properly manufactured and high-quality installed septic tank is able to effectively cope with the functions assigned to it.

Before deciding on this option, you need to learn about some of its features. Firstly, homemade design and its further installation will require enormous labor costs. You may have to resort to the help of 1-2 friends, acquaintances, or hired workers.

This is due to the large volume of excavation work - you will have to dig a lot. Also, in order to lower the already prepared container into the dug pit, you will need outside help. Despite the light weight of the structure, do not forget about the dimensions. It will be difficult to cope with such a giant alone.

Secondly, this option for solving the issue of local sewerage will only be successful if it is installed correctly. Otherwise, the septic tank may collapse in a couple of months or a year under the influence of environmental factors. All efforts and funds spent on the project will be in vain.

Thirdly, it should be taken into account that additional cleaning will definitely be required - after all, a septic tank made from Eurocubes is capable of purifying wastewater by 50-60%. The water coming out of it must necessarily pass through some kind of filter. You should think about this at the design stage in order to calculate everything correctly. For example, to arrange filtration fields you will need a decent area.

Assembly and installation technology

Often homeowners, wanting to save as much as possible on sewerage installations, think about how they can make a homemade septic tank from a Eurocube.

This option looks very attractive financially, which allows it to look advantageous against the backdrop of expensive factory installations. Moreover, if you do everything yourself, without ordering a turnkey project, the savings will be significant.

Step #1 - design and calculations

The decision to equip a local sewage system using so-called “flasks” or Eurocubes occurs quite often. Some summer residents speak enthusiastically about this option, calling it successful, profitable and effective.

Others, on the contrary, say that having once spared money for high-quality factory equipment, they had to pay twice - such a septic tank was crushed by soil in a matter of days.

Both supporters and opponents are right in this dispute. In fact, these containers can successfully serve as a septic tank only if they are installed correctly. It is important to consider the type of soil in a particular area. If you ignore this point, the container will simply compress and you will have to start all over again.

Before you start assembling a septic tank with your own hands, you need to calculate the water consumption consumed per day for household needs and discharged into the sewer. This is convenient to do if a counter is installed. Otherwise, you will have to calculate the value yourself.

It is not advisable to take the recommended rate of 200 liters per person per day, because often a family of 5 people uses only 400-500 liters. The real value will have to be multiplied by 3. This is exactly the volume of the septic tank - it should contain wastewater for 3 days.

Having decided on the volume of the container, you have to choose optimal place to place it. Here it is worth considering that the pipes to and from the septic tank go in a straight line, without bends. Otherwise, blockages will often occur that will have to be eliminated.

First, you have to dig a trench to lay the supply pipeline, through which the sewage will flow into the first container - the receiving tank. Then you need to dig a pit for the septic tank, taking into account its dimensions and adding an additional 15-20 cm on the sides for proper installation.

The depth of laying pipes connected to the treatment plant must be below the freezing level, but not deeper than 3 meters from the surface.

Next, you need to dig a trench for the outgoing pipeline and choose the option of additional treatment of the wastewater leaving the septic tank. After all, they will be purified by 50-60%, which is extremely low for safe disposal into the nearest body of water or onto the terrain. The liquids must undergo further purification:

in the filter well;
on filtration fields;
on filter mounds (embankments).

It is one of these options that is most often used. Therefore, it is important to immediately provide space for the installation of an additional filtration zone.

The next stage is the transformation of the Eurocube into a septic tank. For these purposes, it will have to be slightly modified using pipes, tees and consumables. The container itself is sealed, the wall thickness is from 1.5 to 2 mm. It is made of polyethylene, which can withstand caustic substances and acids without reacting with them or being destroyed.

When converting the flask into a septic tank, the drainage area must be hermetically sealed to avoid wastewater leaking into the ground. The same should be done with the second and third cube, if the future septic tank will consist of more than one chamber. Most often, home craftsmen use 2 or 3 eurocubes. Options with 1 or more than 3 are rare.

For a septic tank, you buy containers intended for non-food products. Moreover, you can save significantly by choosing an unwashed used flask. It is easy to wash it with water, and complex contaminants will not in any way affect the effectiveness of the future septic tank.

The standards for connecting the sewer pipe should be taken into account. This is 20 cm below the top edge of the container. Next, you need to place 2 tees inside the container, cutting a hole of sufficient size for this. Subsequently, the holes must be carefully welded and covered with a layer of waterproofing.

The inlet pipe and the pipe going up are horizontally connected to the first tee. It will be used for cleaning and inspection. A pipe will be attached to the second tee to connect the 1st container with the second and a pipe of smaller diameter for ventilation.

Moreover, the outlet from the first flask, through which it will be connected to the 2nd, should be lower than the inlet. All joints and openings are carefully sealed to avoid leaks.

As for the second container and subsequent ones, if they are provided for in the project, then each of them should be located 20 cm lower than the previous one. Based on this, all the holes have to be cut. Their number is the same as for the first flask. Only the outlet in the last Eurocube will be connected to the pipe leading the treated wastewater to the filtration fields. It is advisable to equip it with a check valve.

Step #2 - installation and installation

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

Whether or not to concrete the top of the pit depends on the terrain. 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:

Step #3 - further maintenance

In a private household, every screw requires periodic attention from the owner. Local sewerage is also no exception.

A do-it-yourself septic tank will last a long time only subject to periodic inspections and maintenance. For this purpose, special large-diameter pipes were installed at the installation stage.

On the surface of the drains in the first chamber of 2, 3 or more chamber septic tanks, fatty substances, pieces of polyethylene and other light substances that have entered the sewer float up. Periodically, the layer that cannot be decomposed must be removed mechanically. The frequency of such manipulations depends on the intensity of use of the septic tank and careful treatment of it.

You should also check the amount of solid deposits at the bottom of each container in the fall. If their accumulation is large enough, you will have to call a sewer truck or pump it out yourself. fecal pump. This sludge can be disposed of compost pit for further use as organic fertilizer.

Every spring you need to check how the septic tank survived the winter. Especially if no one lived at the dacha during this period. If damage to the container is detected, work must be carried out immediately to repair or replace it. You should not allow the sewer system to start running with a faulty septic tank - the wastewater can get into groundwater, which will harm the environment.

To speed up the decomposition of organic waste, you can add special bacteria for septic tanks. But if the container is regularly filled with waste water, there is no particular need for this. Microorganisms that feed on organic matter multiply massively and process everything that comes in without outside intervention.

Pros and cons of a septic tank made from Eurocubes

A homemade septic tank made from one or more Eurocubes has a number of positive and negative aspects. It can become convenient and economical option for a private household, solving the issue of installing a local sewer system.

Disadvantages of the cleaning system

It is worth noting that self-assembly and installation of cleaning equipment from Eurocubes will take more than one day. But, if all the work is carried out correctly and in full, the result will please every zealous owner. The following are the most significant disadvantages of this treatment plant:

a large front of heavy work;
strict installation rules;
need for periodic maintenance;
short service life.

If excavation work is not scary and there is no desire to invite help, then digging a pit and trenches can be done alone in a week or two. Everything will depend on the duration working day home handyman - the work is not difficult, but physically difficult.

As for the strict rules, failure to comply with them will lead to the fact that the septic tank will collapse and all work will have to be carried out anew, except for digging trenches for pipelines. Moreover, you can read many reviews on the Internet about this scenario.

In an effort to quickly install a sewer system on private property and sacrificing the quality of work, the owners received an extremely unsatisfactory result. If you want to do everything quickly with a minimal investment of effort and time, then it is easier to buy ready-made biological treatment equipment with installation by specialists. This will turn out to be cheaper than spending two or three times on building a septic tank from scrap materials.

A homemade structure, like many other types of sewerage installations, will require periodic maintenance. Indeed, in the container itself, insoluble substances in the form of fat, accidentally washed away plastic bags and other items will accumulate in the top layer. Such waste will have to be caught from the surface, and solid silt deposits will need to be removed from the bottom.

A treatment facility constructed from Eurocubes is capable of processing wastewater for at least 10 years. Moreover, its service life will directly depend on the type of material used when installing the containers.

If a frame was made around it from boards that were not pre-impregnated with a special protective composition, then such a structure will rot very quickly. In the future, everything will have to be excavated and additional work carried out - after all, a Eurocube simply buried on the site cannot serve as a septic tank. To prevent it from being crushed, you need to perform a number of measures depending on the type of soil and its mobility.

Advantages of a homemade septic tank

Homemade equipment made from Eurocubes can become a reliable part of the sewer system in a country house/cottage. It has a number of positive qualities:

simple and inexpensive components;
ease of container preparation;
reliable wastewater treatment;
possibility to install additional sections;
assembly of the system does not require special knowledge and skills;
complete energy independence.

The system does not require electricity to operate, which is the most significant advantage for many summer residents. Sometimes this factor is decisive when choosing the type of local sewerage system.

The price of containers is relatively low, especially if they are used, plastic pipes, cuffs, tees, other components and Supplies allow you to build an inexpensive septic tank. This attracts hardworking home owners with skillful hands.

An undoubted advantage is the ability to add one or two additional sections at any time, i.e. increase the total volume. To do this, even at the design stage, it is necessary to install a spare pipe by sealing the hole. You should also choose the installation location so that additional sections, if necessary, will fit on the site.

If these conditions are met, then when you are planning to connect an additional container, all that remains is to dig a pit for it and prepare it accordingly. Next, all that remains is to connect the new Eurocube with the already installed one into a single system, using previously supplied and preserved pipe outlets.

A plastic container made of dense material can last a long time. But due to the absence of stiffeners and the presence of an external metal grid that protects it from compression, various scenarios for the development of events are possible. Such a septic tank will be afraid of corrosion - if the frame collapses, plastic container will quickly crumble.

Therefore, it is possible to talk about a service life exceeding 10 years, but with a reservation regarding the materials used during installation. The more durable and reliable they are, the longer the homemade septic tank will work.

The polyethylene container itself can last for decades if substances that can destroy plastic - chlorine, fluorine, 50% nitric acid solution - are not poured down the drain.

Design and operating principle of a septic tank made from Eurocubes

A septic tank made from Eurocubes is a single sealed system that consists of one or more containers. The sewage system is connected to the first tank, and the wastewater enters the tank, where it is roughly cleaned.

The sewage settles and is divided into several fractions with different specific gravity, namely, sediment, gases and clarified water, which is located 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 an overflow pipe, water from the first container passes into the second, where it also settles and fermentes.

The wastewater clarified in the second tank is approximately 60% cleared of impurities. Next, the water goes into the drainage system, where it undergoes soil purification. 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. The liquid is pumped out using a sewer truck through a 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. There is a drain valve at the bottom of the container.

Each Eurocube is enclosed in a metal frame and mounted on a wooden, steel or plastic pallet. Like many other plastic containers, Eurocubes have their own standard sizes, so the question: which one to buy rarely arises. A container with a volume of 1000 liters is considered standard, its length is 1.2 m, width – 1 m, height 1.16 m, weight about 50 kg. The Eurocube is a practically ready-made tank and requires only minimal installation work, which is why sewage systems with a septic tank made of polyethylene tanks are becoming increasingly popular.

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 construction and sanitary norms and rules; these are the main documents that determine the construction 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 appropriate organization.

When building a septic tank, it is important to pay attention to some features of its installation in certain conditions.

The installation depth of the septic tank, regardless of its design, should not be less than the freezing limit of the soil; if the requirement is not feasible, the septic tank must be insulated.
The soil must have high permeability; sandy and sandy soils are considered optimal.
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 cesspools, it will require pumping and you need to take care of the possibility
equipment entrance.

Calculation of septic tank capacity

In order for the sewage system to be functional, and the installation of a new septic tank in a private house not to be in vain, you should calculate in advance the expected volume of wastewater, 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 it is less, they take this number into account 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 during which the water in the septic tank is purified 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, you will need 2 eurocubes. 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 made from Eurocubes differs from other treatment facilities in that additional equipment will be required

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

Before you start installation work, think over the design and location of the septic tank on the site, decide which one is best to install so that the sewage system in a private house is functional and coordinate the plan with 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 will be placed in this gap to protect the septic tank from compression.

The required depth is determined taking into account the size of the Eurocube and the slope of the common pipeline. Height is also taken into account concrete base under the septic tank and the fact that each subsequent container is installed 20-30 cm lower than the previous one, respectively, the bottom is screeded with a step, and fastening loops for the Eurocube are installed in the fresh solution.

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

The next stage of excavation work will be digging cesspool trenches for a filtration field or well. The work may vary depending on the selected method of soil purification.

Septic tank drainage system

Soil purification can be organized in several ways.

Filtration wells are a simple and inexpensive structure; they are a well, the bottom of which is made in the form of a filtration pad made of sand and gravel. But it is prohibited to install it on many types of soil: sandy loam, sand, cracked soil and loam. The productivity of the wells is small, and the installation must be coordinated with the sanitary and epidemiological service.
Underground or above-ground filtration fields are a kind of irrigation system through which wastewater processed by a septic tank passes and enters the soil. Set up a system of ceramic or plastic perforated pipes laid on the filtrate. At the end of each channel, a ventilation riser is installed to a height of up to 0.5 m.

Filtration trenches are pits up to 1 meter deep, into 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-developed scheme, adhering to the basic rule - all connections must be absolutely sealed; builders do not have a consensus on which sealant is best to use.

Assembly begins by preparing the first container. From the top edge of the Eurocube, step 20 cm down and make a hole for the pipe that will connect treatment plant with an external sewerage system. On the opposite side of the cube, at a distance of 30 cm from the top, a second hole is made for overflow, through which the waste will flow into the second container.

Several holes are also made on the second Eurocube. The first is cut out for the overflow pipe, which will connect the container to the first tank. The height of the cut is calculated taking into account that the second tank will be located 20 cm below the first. On its opposite side, 15-20 cm below, a hole is made for the second overflow pipe; it will drain pre-purified wastewater to the filtration field.

On top of each tank it is necessary to arrange a hole for cleaning and ventilation duct. As a rule, only one hole is made at the top, and a pipe is fixed in it for cleaning, and the ventilation riser is brought out, using a ready-made hole in the filler neck. The pipe is selected of 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 container below the overflow pipe.

Advice! If the ventilation riser is made collapsible, then liquid can be pumped out of the septic tank through it in the future and no additional hole or pipe outlet will be required for cleaning

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 polystyrene foam, do not forget about insulating pipes that are located above the freezing level of the soil.

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

Septic tank maintenance

In order for the septic tank, and therefore the sewage system in the house, to work smoothly, it is important to prevent the containers from overflowing and to follow some simple rules.

If you need to download contents to
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 a 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 disposal equipment, so you should take care of the entrance in advance.
If you additionally introduce special mixtures of bacteria for septic tanks and cesspools, pumping
will be needed less often.
After installing a septic tank, it is strictly not recommended to flush rags, matches, napkins, hygiene products and even toilet paper into the sewer.

How to properly and effectively organize sewerage in a summer cottage with your own hands is a question that often arises among people who are deprived of the opportunity to use a centralized option. And indeed, the need for an autonomous, and most importantly effective, sewage and waste disposal system is simply necessary for the comfortable existence of a modern person in a private wooden house.

There are many different materials available as a base for wastewater. Let's consider one of the simplest and most effective of them - a do-it-yourself septic tank made from Eurocubes.

Memo: Eurocube is a container for transporting large volumes of liquid.

It turns out that we remove the pipe from the house at a depth of 50 cm, until the sewer pipes reach the septic tank, the depth will be approximately 56-62 cm, we insulate the pipes (with foam plastic or mineral wool - somehow we don’t want to drill frozen soil in winter), then the septic tank itself and the absorbent field/drainage well. We anchor the septic tank itself so that it does not float up in the spring with the rise of groundwater, we strengthen/insulate the walls so that the soil does not squeeze the septic tank. It turns out that from the surface to the top of the septic tank is about a meter. We insulate the septic tank from above and fill it with crushed stone/earth.

Even a person with little knowledge of construction will be able to make a septic tank from a Eurocube with his own hands; it is enough to know a few basic rules.

The advantages of the Eurocube compared to other options for constructing a septic tank are undeniable:

Its price is quite low compared to similar designs (plastic septic tanks).
The time required to install such a septic tank will not exceed 2-3 days, provided that you perform all the main work alone.
The plastic from which the Eurocube is made is durable and has excellent waterproofing.
Such a septic tank requires a minimum of additional work; there is no need to cover it and additional finishing, unlike a septic tank made of concrete rings.

Tip: it is preferable to have no more than two drainage containers, this will reduce the total number of connections between the chambers, but will not affect the efficiency at all.

Next, armed with a shovel (or hiring the necessary equipment), we begin to dig a pit with our own hands. Due to the fact that the Eurocube is sealed and an additional drainage system will be used to drain sewage, the location of such a septic tank can be in any convenient place.

Note: upon completion of installation, you need to make sure that all pipe connections are tight. As additional insulation, it is worth using a special sealant or liquid rubber.

This is what an almost finished septic tank looks like

The second chamber is equipped with a special drainage pipe (several pipes can be used), which is located at a level of 15-20 cm from the bottom of the cube. To improve drainage capacity, it is advisable to additionally build a drainage well or filtration field.

Advice: it is better to make a ventilation pipe from several elements, so that if necessary, you can disconnect the upper part and use it to pump out waste.

In the second chamber, the ventilation pipe should also be located at a level of 10-15 cm, but already from the drainage pipes.

After preparing and checking all the connecting elements, the Eurocubes take their designated place in the pit and are re-fixed, this time, with the pipes.

Alpine slide - filtration field

If the level groundwater is high, then you have to make a bulk filtration field - it can be designed in the form of an alpine slide :).

A septic tank made from Eurocubes crushed the soil

The final stage is the formation of a concrete screed around the outer wall to protect the cube from soil pressure on it. If the soil is quite loose, you can get by by simply compacting sand around the cubes or installing OSP panels/slate/corrugated sheets.

At this point, the process of creating an autonomous sewer system can be considered complete.

For drainage, you should use special perforated pipes sprinkled with coarse crushed stone. Crushed stone will prevent pipes from silting and at the same time has excellent throughput.

If possible, try to use additional means of wastewater disposal, for example: a filter well or special biological mixtures.

Plastic is very sensitive to low temperatures, so you should not allow it to be completely filled in winter; in severe frost it can simply crack from internal pressure. One way to avoid this problem is to build a septic tank below the freezing level of the soil or by additionally insulating it.

To make the Eurocube more stable from the impact of soil, you can make its outer sheathing with rocky wire.
