Many private houses are not connected to the central sewerage system. Their owners are getting out of this situation different ways. Long used cesspool as one of possible options arrangement autonomous sewerage, but this is not very convenient and practical.
This technology is being replaced by more modern methods. Nowadays, various septic tanks are widely used. These devices allow you to create excellent sewage systems, while wastewater are cleaned to such a level that they are suitable for watering and irrigation.
A septic tank made from Eurocubes is one of the most simple options autonomous sewerage. Eurocube is a container that is designed to transport impressive volumes of water or other liquid.
Sewage from Eurocubes will be for a long time serve faithfully to your master.
How to make a septic tank from Eurocubes with your own hands
First, you need to carefully prepare, namely, make calculations that will help determine what volume the Eurocube should have. To do this, you need to calculate the approximate volume of wastewater that will pass through it per day. In any case, you need to buy Eurocubes with a reserve. This nuance should not be forgotten.
Now you can start digging a pit. The Eurocube itself is a sealed element. An additional drainage system will be used to drain wastewater, so Eurocubes can be placed anywhere on the site.
We proceed directly to the process of installing a septic tank from Eurocubes with our own hands. At the bottom of the pit, a cushion of sand and crushed stone is made. In the event that there is a possibility that the soil will float, it is better to make a concrete screed.
After everything connecting elements prepared and tested, the Eurocubes can take their rightful place. They are placed in a pit. In it, the septic tank is thoroughly fixed with pipes that have passed the leak test by this time.
If the groundwater level is high...
At high level groundwater The septic tank is installed using the same method, but it must be firmly fixed to the bottom of the pit. Eurocube for a septic tank is a fairly heavy material, but the groundwater level can directly affect its position. In this case, Eurocubes can float and damage sealed connections. If there is high water in the ground, it is necessary to do embankment field filtration.
Here it is worth making another container in which the pump is installed. It will pump wastewater into the filter field that was made earlier. It will be very beautiful if you make it in the form of an alpine slide.
Now you can finally fill the Eurocubes with sand. If necessary, such a septic tank must be insulated. In most of the territory of our state, such a procedure is a necessity, since cold period time prevails on it. Can be used for insulation mineral wool, as the cheapest insulation.
At this point, the process of installing an autonomous sewage system from Eurocubes can be considered complete.
The process of filtration and sewerage of such a septic tank is quite simple and primitive. Through the pipes, all wastewater enters the first section of the septic tank. Heavy particles settle in this compartment. They simply remain at the bottom of the first chamber. When the level of waste becomes high enough, the wastewater flows into an adjacent chamber. You can use a height difference for this, or make a drain pipe at a certain height.
The second chamber contains a special drainage pipe. It should be at a distance of 15–20 centimeters from the bottom of the cube. To improve drainage capacity, you can build a filtration field or drainage well.
Both chambers of the septic tank must be equipped with ventilation pipes. These pipes should protrude approximately two meters above the ground level. In this case, in the first chamber the pipe is located approximately 15–20 centimeters above the connecting pipe. It serves to eliminate harmful fumes. In the second chamber, the ventilation pipe is also located at a distance of 15–20 centimeters, but this time from the drainage pipes.
Thus, the design of a septic tank made from Eurocubes is quite simple. It should be understandable not only to professionals, but also to all those who decide to arrange a autonomous system sewerage.
Whenever possible, it is recommended to use additional funds. These include specially created biological mixtures or a filter-type well.
Plastic is a very sensitive material. He is influenced low temperature. IN winter period You should not fill the septic tank entirely from Eurocubes. This can lead to cracks and system failure. To prevent this from happening, you can place the septic tank below the freezing level of the soil or use insulation. As mentioned earlier, ordinary mineral wool is ideal.
To make the septic tank more stable, its outer sheathing can be made using steel wire.
As you can see, such a septic tank is installed quite simply. In order to make it, you do not need any supernatural knowledge or skills. In addition, all the materials that will be needed to install a sewer system are widely available. You don't have to run to different stores. Everything can be purchased in one place.
Video: septic tank from Eurocubes
To build a septic tank, it is not at all necessary to build bulk concrete containers. Local treatment plant with low productivity you can make it yourself from Eurocubes or nylon containers. This article will discuss the design and installation stages of such a septic tank.
Homemade septic tanks inherit the operating principle ready-made solutions, such as “TOPAS” or “TANK”, but structurally they are very different. It is almost impossible to divide the container into chambers: polyethylene is difficult to glue in artisanal conditions, and the narrow neck makes work difficult. Therefore, several adjacent containers connected to each other are used.
What containers can be used
For a septic tank, it is advisable to use used containers without damage to the body with the shape of a vertical cylinder or parallelepiped. The thickness of the walls of the container must be at least 3.5 mm, and the thickness of the Eurocube - at least 2 mm.
Due to their small capacity (1000-1050 liters), Eurocubes are used in septic tanks with a daily capacity of up to 1 m 3 per day; in other cases, nylon containers are used. Their volume is not difficult to calculate - the total capacity of the septic tank is chosen equal to three times the daily drainage value. And when the number of discharges exceeds 5 m 3 per day, the total volume of the septic tank chambers should be 2.5 times higher.
The dimensions of the aeration tank and the primary settling tank are in a ratio of 1.5:1, the second and third chambers are equal in volume. For example, a septic tank with a volume of 6 m3 has the following chamber capacity:
- Primary settling tank 1500 liters.
- Aerotank - 2250 liters.
- Deep cleaning chamber - 2250 liters.
In treatment plants with a volume of more than 10 m3, all chambers have the same volume.
Features of installation at high groundwater level
Homemade septic tanks from plastic containers It is reasonable to install with low waste loads - up to 6-8 m 3 per day. Unlike treatment facilities with concrete tanks, they have a number of disadvantages.
When the groundwater level (GWL) is below 1.5-2 meters, the septic tank is installed according to the standard scheme. But if the groundwater is higher, there is a real threat of liquid backflow and flooding. In this case, a buffer tank with a higher level is required, into which purified water is supplied via an airlift or drainage pump.
Option for installing a septic tank at a high groundwater level: 1 - wastewater inlet; 2 - first container; 3 - second container; 4 - drainage pump; 5 - ventilation; 6 - buffer capacity; 7 - drainage field
If the groundwater level is too high (less than 50 cm), there is a possibility of flooding of the septic tank through the caisson or gaps in the drainage channel. These problems are solved in the following ways:
- Introductory gasket drainage pipe above ground level with subsequent insulation.
- Construction of a sealed sewer channel.
- Sealing the caisson, using containers with elongated necks.
- Installation of a septic tank close to the soil surface and its insulation.
The last point implies a minimum distance of the septic tank from the riser, but no closer than three meters from the foundation of the building.
Excavation and installation of tanks
The installation of a septic tank begins after laying the sewer channel. For homemade septic tank, unlike factory VOCs, the height of the insertion of the inlet pipe matters - optimally 20-25 cm from the top. Taking this into account, the depth of the pit is determined. The containers are placed in the required order on the leveled soil, then the contours of the future pit are marked, retreating 25-30 centimeters from the walls of the chambers for backfilling.
The bottom of the pit is filled with concrete, reinforcing metal mesh with 4 mm rods and 60x60 mm mesh. The concrete hardens in 2-3 days, after which you can install the first and third tanks, cut in the inlet and outlet pipes, respectively. Convenient to use for pipe insertion wooden block with two self-tapping screws screwed into it, the distance between the tips of which is 1-2 mm less than the radius of the pipe. Using this “compass”, a perfectly round hole is scratched out at the insertion site and the pipe is inserted. It takes some effort, but this method makes the walls fit more tightly.
At the places where the pipes are inserted, the connection is treated with hot-melt adhesive: first with a white transparent rod, and then with a translucent black one. Direct outlet tees are put on the ends of the pipes and placed vertically, the lower end is extended to the middle of the chamber height.
Backfilling and caisson installation
After installing all the containers, prepare a mixture of five parts sand and one part cement, and fill the gaps between the walls of the tanks and the pit with it. This is done in several stages. First, fill and compact the bottom layer to 1/4 of the height, filling the septic tank by a third with water. Subsequently, backfill is carried out to half, and then to 2/3 of the height.
When installing at shallow depths, it is reasonable to cover the septic tank with expanded polystyrene slabs before backfilling. When the backfill covers the inlet pipe, the EPS slabs are cut and laid horizontally, then the septic tank continues to be filled to the level of the upper wall of the tanks.
A caisson is a technical chamber designed to accommodate equipment. The walls of the caisson are laid out in half a brick so that they protrude 10-15 cm above the ground level, the bottom is poured after inserting the passage sleeves into the upper wall of the chamber. When pouring the screed, the neck of the septic tank is protected with ring formwork, for example, made of plastic. The caisson can be common or individual for each chamber. In the latter case, pass-through sleeves for pipes and hoses are placed in the partitions.
Internal filling of the septic tank
The only electrical equipment used in a septic tank is a compressor, such as Pondtech A-85. An airlift system is used to pump the mass. The airlift for pumping liquid from the primary settling tank is placed at the level of the inlet pipe, and in the aeration tank it is located 10-15 cm from the top of the chamber. The discharge outlets are lowered to the middle height of the container. To pump activated sludge from the aeration tank and deep cleaning chamber into the primary settling tank, two separate airlifts with common point discharge 70-100 cm from the bottom. The airlift suction pipes are located 10-15 cm from the bottom, and the pump itself is placed at a third of the height of the chamber.
Corrugated spiral hoses of 32 mm are excellent as transfer channels; they can be easily laid without sharp turns. The connection to the airlifts is sealed with screw clamps or nylon ties.
1 - inlet pipe; 2 — membrane diffuser (aerator); 3 — concrete pouring; 4 - airlift for pumping into water; 5 - compressor; 6 - cement-sand backfill; 7 - caissons; 8 - air lift for pumping sludge; 9 - outlet pipe
Airlifts can be made with your own hands. To do this, take a segment PVC pipes 32 mm 15-20 cm long, drill two 15 mm holes in it in the middle and screw fittings into them for a 12 mm hose with a 1/2 thread. The connection turns out to be quite tight, if desired, it can be treated with hot glue. Two pieces of hose are put on the fittings and connect them with a tee.
From the compressor, air is supplied to membrane diffusers located 40 cm from the bottom of the first and 25-30 cm from the bottom of the second chamber. To power airlifts, tee branches are made, and air is passed through flow regulators. Airlifts for pumping sludge are additionally equipped with taps or electric valves for automatic control.
Completion of installation and start-up
IN highest points For each container, usually in lids, it is necessary to install exhaust ducts to remove ventilation gases. After this, the septic tank is filled with water and its operation is tested in “clean” mode: the air supply to the airlifts is adjusted and the pumping speed is checked. If the operating mode suits you, the septic tank can be started.
Eurocube What it is?
A Eurocube is a special container that has a cubic shape. It belongs to the class of so-called “medium-tonnage containers”. It has a rigid outer packaging with steel lathing and an inner tray that can be made of metal, wood or plastic. The container itself is made of special polyethylene.
The sizes of the Eurocube may vary. There are various specifications of Eurocubes, which differ primarily in the thickness of their walls (from 1.5 to 2.0 mm). On top of the flask there is a special hole in the form of a neck with a diameter of 150 mm. A polyethylene cover is installed on it, which may have ventilation (valve).
A tap is installed at the bottom of the container to drain the liquid. It may have a ball or plunger valve type. Usually the faucet also has a rubber nozzle.
What types of Eurocubes are there?
The Eurocube is used for a wide variety of needs that may arise not only in a specific area, but also in everyday life. Depending on what specific goals you set for yourself, you may need different types similar containers. To date Eurocubes are divided into :
- Containers with a plastic tray.
- Containers with a metal tray.
- Containers with a wooden pallet.
- Containers lined with metal rods.
As you can see, the main distinctive feature each type is the material that is used to make their pallets, as well as the presence of metal sheathing.
In addition, there is the following division of Eurocubes:
- Food containers . Designed to store food (oil, vinegar).
- Technical containers . Used for transportation and storage of alkaline and chemical substances.
What are Eurocubes used for?
Another name for such containers is IBC container. Such containers can be used in various fields, but most often they are used to transport liquids. To date, no more convenient and effective analogues have been invented. Many people use Eurocubes for personal purposes.
How to use and apply the Eurocube at the dacha?
The main purpose of manufacturing such containers is the ability to transport large volumes of various liquids without any problems. That is why Eurocubes are primarily used in production. But, since these containers are characterized by a long service life, excellent characteristics, high reliability and quality, the use of Eurocubes in the country has become a fairly common practice. You can use the container for quite a wide range of purposes.
Always rinse the container under water before use. running water. This is especially true for used Eurocubes. If you want to use a container for storing water (for drinking purposes or for watering plants), then pay attention to what exactly was transported in it before. It is not recommended to use containers that have previously contained chemicals or other similar substances.
Let's take a closer look at which areas you can use Eurocube :
- To collect water. Watering the garden
- For a font or yard shower.
- For a septic tank.
- To store animal feed or as a water trough for livestock.
- For aquaponics.
Today many owners country houses Eurocubes are used so that you can quickly and easily collect rainwater . When it rains, drops of water will flow freely down the lid of the containers directly inside. The Eurocube for collecting water is quite simple and simple device. Moreover, you can use two containers at once, which can be placed on top of each other and placed under the roof of the house.
Undoubtedly, rainwater not suitable for food or drink. Even a special mesh that will protect the liquid from dust and dirt will not help you here. But a similar tank of water is suitable for household use: water the garden, wash the car or dishes, flush the toilet.
Please note that you will be able to collect about a liter of water from one square meter roofs. A water collection container made from a Eurocube is also convenient because it has a special tap, which greatly simplifies the use of the water inside.
Summer shower or font from a Eurocube They will definitely come in handy at your dacha. After all, how you want, after a hot summer day spent in the garden, to plunge into cool water and wash off all the dirt before entering the house. This design will also be useful for those who are just building a summer house on the site and cannot pamper themselves tap water. To create Summer shower, you need to build a metal frame and place a Eurocube on top of it, into which water will be supplied. Typically a 1000 liter container lasts for one month.
Do you like saunas? Then you definitely need to build from European cups font . Even though it's enough cheap option, but it will perform its functions 100%. To make such a structure, you need to cut off the top of the container and line it with clapboard.
Don't forget to think about how the water will be supplied and drained.
Septic tank from Eurocube has become a fairly popular option among modern summer residents. This can be explained by the fact that this type of sewerage is cheaper and more accessible. To create a septic tank, you need to purchase two or three containers with pipes and taps already provided for water drainage.
Please note that everything must be completely sealed. Install the Eurocubes in a pre-prepared concrete pit.
Don't forget: one of them must be lower than the second. Weld the Eurocubes together. Insulate all sides with polystyrene foam and fill with additional concrete. Before pouring concrete, fill the containers with water. This way they don't become deformed.
Container for storing feed, fertilizer or water for animals can be created without any problems using Eurocubes. What is very important here is the fact that such containers are created from special type polyethylene, which does not enter into any reaction with chemicals. The Eurocube will be no less convenient for garbage disposal .
Today it is very fashionable to become aquaponics method . It involves growing plants in water where fish live. This method prevents the accumulation of pesticides and other harmful substances in products.
As you can see, using a Eurocube at the dacha is a fairly effective practice.
Typical Eurocube sizes
The dimensions of the Eurocube, as well as other similar containers, are standard. If you purchase a container for yourself, you can see all the information about its dimensions at the top. The most common are 1000-liter Eurocubes, so we will present them standard size below:
- Length: about 1200mm (+/- 10mm)
- Width: about 1000mm (+/- 10mm)
- Height: approx. 1160mm (+/- 10mm)
- Volume: 1000 l (but can be 50 l more)
- Weight: approx. 53 kg (+/- 10 kg)
Manufacturers who produce Eurocubes try to strictly monitor the dimensions of the containers. Therefore, during the purchasing process, it will be quite easy for you to decide which one is best for you.
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 effectively clean drains and long years work smoothly. 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 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 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 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 soil purification takes place. As a result of fermentation in the first and second chambers, a certain amount of methane is released, carbon dioxide and hydrogen sulfide, 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 metal sheathing 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 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 relevant 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 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
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 starting installation work, they think through 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. They also take into account the height of the concrete base for 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 step earthworks There will be digging of 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.
- Fields of underground or above-ground filtration represent 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 they output ventilation riser 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 a pipe that will connect the treatment facility 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.
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 a cesspool made of 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. Most profitable solution in this situation, the use of plastic containers will be used, 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 have recently been using Eurocubes 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 from steel mesh, providing 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;
- ability to perform installation work on one's own;
- 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. Before installing it, you do not have to carry out complex preparatory work. 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 that should be calculated for 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 the external pipeline of an autonomous sewage system for a cottage or house, 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 connected to each other with polypropylene. The device is 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 prevent cracks, it is necessary to construct a drain tank that will be located below the freezing point. Alternative solution there will 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 in order to sewer pipe there was no rarefied air remaining, 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 final stage. The design of the drainage system can only be constructed if the soil on the site is 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. For this metal frames containers are welded together. For this you need to use a metal rod.
