Holidays at the dacha are pleasant only if all the benefits of civilization are present there. For modern man The presence of water supply and sewerage is one of the criteria for comfort. And if in apartment buildings There are no problems with this, but in the private sector residents have to look for a way out of this situation. Sometimes, wanting to save money, people equip an ordinary drain hole. In this case, in addition to the low cost of building other positive points No. It is much better to build a septic tank from Eurocubes with your own hands, which will serve you for more than a year. Moreover, this is one of the most simple ways arrangement of sewerage in a country house.
What are the advantages of a septic tank over other structures?
- preventing the spread of unpleasant odors;
- absence of soil contamination by human waste products;
- there is no need for the services of vacuum cleaners; cleaning a septic tank is done quite rarely and can be done independently;
- A septic tank will last much longer than a cesspool.
Choosing the right container volume
The size of the septic tank is selected depending on the number of drains. Their volume is determined depending on the period of operation and the number of residents in the house. For temporary use in summer period a small-volume design is suitable, and year-round use of a septic tank requires daily discharge of wastewater.
Their volume is determined by the number of people living in the house. It is assumed that the daily water consumption per person is 200 liters. Based on this value, the daily water consumption for all residents is determined. The volume of the septic tank chamber should be three times larger than this figure. It is advisable to choose a septic tank with a slightly larger volume, taking into account the unexpected increase in wastewater.
Where on the property should the septic tank be located?
The sewerage structure must be located away from the water intake site. Minimum distance is 50 meters. When installing a septic tank, you must move at least 6 meters away from the foundation of the building, but you should not build it too far from the building either.
Since the sewerage system must have a sufficient slope, every extra meter leads to a decrease in the installation level of the septic tank. In addition, in a long pipeline there is a high probability of blockages. To eliminate them you will have to build inspection wells. Also, the septic tank should not be located closer than 3 meters to the neighboring area.
Preparing the pit and base for installation
To build a septic tank from Eurocubes, the first step is to prepare a pit for containers and a trench for sewer pipes. The size of the pit for the septic tank is taken based on the volume of the installed chambers plus 15 centimeters on each side. The depth of the pit depends on the size of the Eurocubes and the slope of the sewer line, which must be at least 2 centimeters per meter of pipeline.
The bottom of the pit is filled about fifteen centimeters with concrete. During this process, you need to make loops to “anchor” the cubes so that they do not squeeze out groundwater. A trench is dug from the house to the septic tank installation site. The trench should slope towards the septic tank.
Preparation of Eurocubes for further installation
Before starting work, containers must be prepared. At this stage, the drain in the lower part of the container is sealed, and holes are made in the Eurocubes themselves for inlet and outlet pipes and ventilation.
The drain at the bottom of the Eurocube must be sealed to prevent leakage
To prepare 2 Eurocubes for use as a sewer, you will need four tees and pipe sections (d=10-15 cm). To insert the tee, a cut is made around the neck in the shape of the letter P and the edge is bent.
In order to insert the tee into the container, you need to make a cut. Its size must be sufficient for the passage of the tee
In the first cube you need to make a hole for the pipe coming from the house. A piece of pipe of the required length is cut, inserted into the resulting hole and connected to the tee.
The sewer pipe from the house is brought into this hole. When connecting pipes, do not forget to check the presence of rubber bands
The tee is inserted into the container and connected to the inlet pipe
For ventilation, a hole is cut above the tee and a piece of pipe (d=5 cm) is inserted. On the other side of the container, an outlet hole is made, which should be located below the inlet. The same hole is made in another Eurocube, but taking into account that the cube will be located 20 cm lower than the first. This is necessary for full use of the volume of the second container. Tees must be connected to the pipe connecting both tanks, with ventilation outlets installed on top of them.
On both sides of the pipe connecting the tanks, it is necessary to connect tees and install ventilation outlets
A hole is also made for a drainage pipe leading to the aeration field. After all pipes have been installed, the joints should be treated with sealant.
All connections must be carefully treated with sealant
The seam around the neck is fastened with rivets and also treated with sealant. A waterproofing layer is fused on top.
A waterproofing layer is fused to the cutout around the neck
To ensure that the containers do not move relative to each other, they must be securely fastened to each other. To do this, the frames of the Eurocubes are welded together. For more durable fastening, reinforcement is used.
After the Eurocubes are firmly fastened together they are ready for installation
Installation of Eurocubes in the pit
The prepared Eurocubes are installed in the pit and attached to the prepared loops with a cable. Where soils tend to swell, it is necessary to protect containers. To do this, you can lay corrugated sheets or antiseptic-treated boards on all sides, or fill the distance between the soil and the walls of the cubes with concrete. In this case, the frame of the containers will serve as additional reinforcement. Before pouring concrete, the containers must be filled with water, and the process itself must be carried out gradually and very carefully.
Note! The walls of the Eurocube are very thin, so the process of pouring concrete requires extreme caution.
Using polystyrene foam, the walls of the containers and the top are insulated. The entire structure is covered with wood or concrete.
The walls and top of the Eurocubes are insulated with foam plastic. This will help prevent the septic tank from freezing in cold weather.
In any case, like this homemade septic tank from Eurocubes does not completely clean waste water. Therefore, for complete cleaning, it is best to equip a drainage field. Only in this case will the sewer system be complete.
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.
For manufacturing you do not need to be a specialist, 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: their rectangular shape is very convenient for installation, and they have 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 concern 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 | The 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 a rate of 200 liters per day for calculation - often much less water is actually used. 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 EurocubesChoose 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:
- 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.
- 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.
- 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 the 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, required thickness– 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, the usual scheme Some changes are made during installation. 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 of the liquid solution does 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 be able to withstand the pressure thin plastic will crack.
At high groundwater levels, constructing a drainage well is impossible. There are 2 options for solving the problem: forced pumping of liquid with a pump or a 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 groundwater level They make an additional tank. You can use another Eurocube so as not to seal a structure made, for example, from concrete rings. It is installed drainage 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, sealant in this case is used for sealing.
Among large quantity construction options engineering communications for the dacha and country houses A septic tank is most suitable. In the process of its equipment, the installation of storage containers is required, for which various containers are used. Eurocubes are suitable products for creating a septic tank.
What it is?
A septic tank made from Eurocubes is a structure consisting of containers made of plastic and arranged in a welded frame made of steel profiles. Polyethylene is used to produce septic tank containers. This material has increased resistance to chemicals and does not lose its properties if the device interacts with an aggressive environment.
In order to further protect the septic tank from Eurocubes, the polyethylene container is strengthened with inside special corner shields. Eurocubes have the following advantages:
- Tightness of the septic tank. Such a septic tank element will not allow liquid to pass through.
- Eurocube can withstand significant loads. This is achieved thanks to the steel structure and ergonomic design in the form of a cube.
- High resistance of the septic tank to negative external influences. For this purpose, galvanized steel is used in the manufacture of the septic tank. High Quality and the welding technology is followed.
To create a septic tank without pumping at the dacha, Eurocubes are ideal, since they have suitable device and are specially designed for storing and moving aggressive environments, and are not subject to destruction under their influence.
Advantages and disadvantages
Device sewer system at the dacha using a septic tank without pumping has pros and cons. The advantages of a septic tank of this type can be attributed:
- Installing a septic tank from Eurocubes takes a minimum of time.
- Containers have reasonable prices.
- The containers have good waterproofing and a long service life.
- The septic tank requires minimal additional preparation.
- Ease of operation of the septic tank.
Septic tanks made from Eurocubes also have disadvantages:
- If the area is flooded by flood waters, the container will be pushed out of the pit due to its low weight. To avoid unpleasant situation possible by fixing Eurocubes to a concrete base. To do this, use cables or special tightening belts.
- The septic tank is thin and can be damaged when exposed to increased loads.
Device and circuit
The layout of a septic tank made from Eurocubes is as follows:
- Wastewater flows from plumbing fixtures and other sources through pipes into one of the septic tank tanks, where the particles will separate and settle to the bottom.
- When the wastewater reaches the designated level, it will flow through the connecting pipe into the next chamber. The septic tank design implies the presence of a height difference between the tanks.
- From the second device, wastewater enters the ground through a drainage pipe, which, according to the septic tank diagram, should be located at a height of approximately 20 cm above the bottom of the Eurocube.
To improve the cleaning system Wastewater a drainage well should be provided. To find out what kind of functioning scheme a septic tank made from Eurocubes has, you should look at the proposed photos and videos.
It is worth noting that according to the septic tank design, both containers in the septic tank must be equipped with a ventilation system. It consists of pipes that should protrude about two meters above the ground level.
When setting up a septic tank with your own hands, you should place the ventilation pipe inside the first container at a height of about 15 cm from the level of the connection of the Eurocubes. It is designed to remove harmful fumes, and will also allow you to pump out wastewater using special equipment. In the second container, the pipes are located at a similar distance.
A septic tank made from Eurocubes functions by mechanically separating large fractions found in wastewater. This procedure is carried out due to the design of the sewer system with two levels, which allows you to create an overflow effect. To better understand how this happens, it’s worth looking best photos and a video on this topic. Also, when installing a septic tank from Eurocubes with your own hands, you can read reviews from those who have done this before and are familiar with its structure.
Under the influence of bacteria in a septic tank without pumping, anaerobic decomposition of waste occurs. You should initially add special bioactivators to the container in order to achieve better conditions to break down the aggressive environment.
Thanks to a similar septic tank design without pumping and use this method treatment, the amount of insoluble waste will not exceed one percent of the total volume of wastewater. For this reason, when setting up a pit for a septic tank at your dacha, you don’t have to worry that if they get into the ground, they will cause significant harm to the environment.
To prevent wastewater from flowing back into the sewer from the septic tank, you should install a special device at the end of the pipe with your own hands - a check valve.
Preparatory activities
When learning how to make a septic tank from Eurocubes with your own hands, you should not miss this important point, as preparation for this procedure. Preliminary activities include the following:
- Choosing a place to dig a pit and then install a septic tank.
- Calculate the volume of septic tank tanks sufficient to dispose of all wastewater in the country.
- Acquisition and preparation the best tools and materials for the construction of a septic tank.
You can learn how to correctly perform these procedures with your own hands from the presented photos and videos. Feedback from those who installed a septic tank at their dacha without pumping will be no less useful.
First stage preparatory work consists of planning a site for the construction of a sewage septic tank on a country site or country house. To achieve the best result, you should adhere to the following recommendations:
- The distance between residential buildings and a septic tank made of Eurocubes without pumping should exceed five meters, and to roads and parking lots - at least two meters.
- The containers must be located in such a way that pumping can be ensured without obstruction. However, most dacha owners prefer to install a septic tank from Eurocubes with their own hands without pumping.
- Sewer pipes should not have bends. If they do exist, you should install additional wells in these places yourself.
- The septic tank pipes should also not have a slope of at least two centimeters per meter of length.
These conditions in some cases make it difficult to install a sewerage system and a septic tank from Eurocubes at the dacha. However, by adhering to them you can get better results in pumping wastewater and prevent the occurrence of unpleasant consequences. Photos presented by experts will help you understand the issue of installing a septic tank.
It is also worth noting that for long pipes you will need independent arrangement a deeper pit in which Eurocubes of the septic tank will be installed. However, when long length sewer pipes may become clogged. For this reason, it is recommended to install an inspection well.
The second stage of preparatory work when installing a septic tank at the dacha is no less important. In the process of calculating the appropriate volume of septic tank containers from Eurocubes without pumping, you should take into account the amount of wastewater that will be generated as a result of the operation of plumbing fixtures in the house. This parameter will depend on the number of people living or visiting the dacha, the number of plumbing fixtures, as well as the intensity of sewerage operation.
Eurocubes can have a minimum volume if suburban area is visited seasonally or the house is inhabited by a small number of people. To equip a dacha with a septic tank of the type in question is the best option. It is also worth noting that installing large containers for a septic tank is a rather labor-intensive process, which can be understood by looking at the photo.
To build a septic tank from Eurocubes with your own hands, you need to prepare following materials and tools:
- Eurocubes;
- Wooden boards with dimensions 10 x 2.5 cm;
- Polystyrene foam as insulation for a septic tank;
- Pipes for providing drainage and ventilation;
- Sealant;
- Drainage pipes, crushed stone and gravel for backfilling the pit;
- Pipes, cuffs and tees.
The number of these elements depends on the design of the septic tank from Eurocubes, as well as the selected installation technology. To do the work yourself, you also need to prepare special equipment or shovels for the work. earthworks. Also, to create the best concrete solution with your own hands, you need to take a mixer. To create holes in the bodies of the Eurocubes of the septic tank and trim the pipes, prepare an angle grinder.
Basic installation steps
To find out how to properly install septic tanks from Eurocubes at your dacha, you should view the proposed photos and videos. It is also worth reading the reviews of those who have already done this. It is worth remembering that in the process of constructing a septic tank from Eurocubes without pumping, you should adhere to technology and consistency.
The first stage of work on equipping a septic tank consists of performing excavation work at the dacha or personal plot. Trenches should be made in which the sewerage pipes will be placed, as well as a pit for installing Eurocubes. Its size should be equal to the volume of the containers with an additional 15 cm for each side. The depth of the pit depends on their height. Gravel is poured onto its bottom and concrete mixture, installing loops for fixing cameras. Step-by-step execution works can be seen in the photo.
The second stage of work consists of assembling the septic tank with your own hands, which will require two Eurocubes. They are first prepared: tees are installed in the neck of the container, a hole is made in the first for supplying a sewer pipe, a connection is provided between the chambers of the septic tank, and the resulting connections are treated with sealant. To reliably connect frames, you can use reinforcement and welding.
After the bottom of the pit has dried and the Eurocubes have been connected to each other, you can begin installation yourself. To do this, containers are placed in the pit and connected via a cable to pre-equipped loops. The containers should be lined with boards if the septic tank is being built on heaving soil. You can also fill the space between the soil and the Eurocubes with a concrete solution.
Insulation of a septic tank is one of important procedures, as the reviews of experts say. To carry it out, you should use polystyrene foam or polystyrene foam. They are installed on top of the work and covered with soil.
The last stage of constructing a septic tank consists of laying drainage pipes. The wiring must be done from the pipe of the second Eurocube. To achieve better distribution of wastewater, it should be backfilled with gravel. On this self installation The septic tank at the dacha is completed.
Maintenance and care
A septic tank that is used in a country house for a long period requires appropriate care. It is necessary to ensure that large fractions, waste and chemical substances. If a septic tank was not installed without pumping, this procedure and cleaning of debris should be additionally ensured. When using a septic tank seasonally, you need to prevent it
In order to prevent damage to the septic tank from the Eurocube at the dacha, you should adhere to the following recommendations:
- When installing a septic tank from a Eurocube at your dacha with your own hands, you should wisely choose its location, taking into account the features of the topography. Thus, the influence of groundwater on the sewerage system will be reduced.
- The object must be thoroughly waterproofed.
- The pit for the septic tank should be lined with boards or concreted to protect it from compression.
- It is also recommended to connect the containers to each other using steel elements, for example, fittings.
When installing a septic tank from Eurocubes yourself, it is worth carrying out the listed measures, which will allow you to minimize all the disadvantages of this type of sewage system.
Every resident of a private house is faced with the issue of sewerage. An absolutely normal desire to find inexpensive option, which is easy to install. As practice shows, special structures are quite expensive, including cesspools. In addition, such structures are quite expensive to maintain.
The optimal solution to this problem would be to create a septic tank from Eurocubes yourself. What is a Eurocube, and how to make a septic tank out of it?
Eurocube is a container made of dense polyethylene with additional support. The support is a steel grating located on the outside.
Making a septic tank from Eurocubes has a number of advantages:
- cope well with heavy loads;
- sufficiently sealed;
- resistant to chemicals;
- quick and easy installation;
- relatively low cost;
- do not require special care.
Along with the advantages, there are also some disadvantages:
- under prolonged heavy loads, the walls may become slightly deformed;
- if the area is prone to flooding, then the small weight of the container will not be able to keep it in the ground. In other words, he will be pushed to the surface.
The process of constructing a septic tank is not very complicated and it can be made without outside help.
First you need to calculate the required number of cubes. One septic tank must contain the volume of wastewater for 72 hours. The calculation can be made according to the following scheme: 1 person uses approximately 180-200 liters. during the day. Accordingly, there is the same amount of waste. We multiply the resulting result by the number of people. So, the volume has been calculated.
The next stage is preparing the installation site. You need to dig a hole that is slightly larger than the container. It should be placed at such a depth as not to freeze during the cold season. After this, it is necessary to prepare the soil for the container. Since the weight of a filled container is quite large, it can easily lead to pipes not being able to withstand the load and bursting. To avoid this, you need to make a substrate of sand and gravel. It won't be superfluous cement strainer above. Using the same principle, the next container is installed, but without a substrate.
Scheme of a septic tank from Eurocubes
- Eurocube into which water flows from the house.
- Additional Eurocube.
- The drain valves are closed and a plastic cap is placed over the sealant.
- The 1st Eurocube should be located 15-20 cm above the 2nd Eurocube.
- Plastic pipes (usually used 110mm thick)
Further, in the walls, which are located vertically and oppositely, two holes are cut out, intended for short pipes, each of them ends with a tee. You can make such holes using a grinder or manually with a hacksaw.
You need to prepare three pieces of pipe, the length of which is about 30 cm. They are needed for the inlet and outlet of wastewater, as well as for fastening between the departments of septic tanks. Usually this simple pipes for sewerage with 11 cm diameter. Pipe cuts can be processed using cleaning discs. The cut and stripped pipes are inserted into the holes made.
The sections of pipes that extend outward from adjacent walls are connected to each other by a small insert.
After this, two tees are placed in each container. This can be done through the neck or using a slot near it.
In the upper part of the Eurocubes, holes are made for the outlet of ventilation pipes, which are inserted into a tee inside the container. Ventilation pipes must be installed, because it is through them that the septic tank receives Fresh air. In addition, such ventilation helps to destroy the organic film that will certainly form.
For greater stability of individual containers, their frames are welded together. This is done using metal fittings or other strips of metal. All connecting seams are treated with silicone, and the joints are reinforced with linings and rivets.
In order to be able to control the pollution process, an inspection grid or pipe is placed in the neck of the largest cube (which always stands first).
After all the tees and pipes are installed, the frames are connected, and the seams are sealed, the septic tank is immersed in the pit. To prevent soil pressure from damaging the walls of the container, they are reinforced with sheets of corrugated sheets or slate. Where the weather conditions are cold, they are additionally insulated with polystyrene foam. In some cases, it makes sense to fill the space between the walls and the ground with concrete mortar.
After all the preparatory work, the outlet pipe located on the second cube is connected to the filters and drainage pipe. Then the septic tank is filled with soil and only the pipe remains on the surface. Provided that the required volumes are correctly calculated, high-quality assembly and installation are carried out, such a homemade septic tank will serve you for many decades.
There is one more little secret. Making a septic tank from Eurocubes is not particularly expensive, but you can save even more. To do this, you need to purchase Eurocubes that have already been used somewhere. They are sold at affordable price, because washing is very expensive. In your case, you don’t need to wash them.
A septic tank made from Eurocubes is the most affordable and suitable option, which can be used in any climatic conditions.
One of the simplest and most economical available options treatment facility for a home or cottage - a septic tank made of Eurocubes. Combined with good drainage, it will clean your drains effectively and run smoothly for years to come. Let's look at how to make a septic tank with your own hands from Eurocubes, in detail with calculations and step-by-step instructions.
Those who are faced with the problem of choosing a treatment facility often have a question: is it worth spending money on a septic tank when you can get by with a regular one? cesspool. It is possible, but it may not withstand large volumes of water from all sanitary facilities, and the aromas hovering around it are not always acceptable in a private area, especially in a small one. In addition, untreated household wastewater can pollute groundwater, then you can smell it or even have a slight taste at the nearest well, and this will not please the workers of the sanitary and epidemiological station.
With a septic tank, these problems can be avoided, but since the cost of industrial structures is quite high, homeowners have to look for an alternative. And the most acceptable option in terms of cost and ease of installation was a septic tank made from a Eurocube.
Construction and
A septic tank made from Eurocubes is a single sealed system, which 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 operating principle of a septic tank made from Eurocubes
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 keep them in 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. Then the water goes into drainage system where it takes place 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 polyethylene high density, the thickness of its wall 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, it can additionally be equipped with ventilation valve. There is a drain valve at the bottom of the container.
The operating principle of a septic tank made from Eurocubes
Each Eurocube is enclosed in a metal frame and mounted on a wooden, steel or plastic pallet. Like many others 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 installing a septic tank are documented in the construction, sanitary standards and rules, these are the main documents defining the design 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.
Norms and rules for the location of the septic tank
- 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 case of clay soil Construction of cesspools and 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 total capacity add 200 liters.
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
Drainage and drainage system
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, protecting 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.
Excavation and concreting of the base for a septic tank
Anchoring will protect the structure from displacement in the event of a groundwater breakthrough.
An important point: to prevent the septic tank from being squeezed out by groundwater in the spring, it must be secured to concrete base belts.
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 systems for septic tanks
- 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 external system sewerage. 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 ventilation tube should not be placed in a container below the overflow pipe.
Assembly and installation of a septic tank from Eurocubes
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.
