Homemade septic tank of eurocubes

The construction of a septic tank from eurocubes is a simple and fairly cheap way to install a sewage treatment plant in the country

Budget type of sewage treatment plant

For the construction of a septic tank will require a minimum of funds. The system does not need electrical power; from the extreme chamber it is necessary only 1 - 2 times a year to pump the sediment.

Step type layout

In an improvised septic tank, drains are separated into water and insoluble sediment in the process of settling under the action of gravity.

Availability of components

Plastic packaging for the construction of such a septic tank to find and purchase is not difficult

Accessories for the manufacture of septic tank

For the installation of a two- or three-chamber septic tank, eurocubes will be required, the number of which is equal to the number of chambers, sewer pipes, sealant, sealing rings, tees, corner fittings

Durability of polymeric camera bodies

Chambers of a septic tank settled from eurocubes are not afraid of exposure to water, as well as chemical and biological environment aggressive

Septic construction process

Flowing from one chamber to another, the wastewater is clarified and disinfected by the action of anaerobic bacteria. The degree of its cleaning reaches 60%

The system of underground wastewater treatment

It should be remembered that after treatment in a septic tank, waste water cannot be directly discharged into the ground. Before disposal, it must pass through an after-treatment system.

The system of underground wastewater treatment

Before you decide on this option, you have to learn about some of its features. First, the self-made design and its further installation will require huge labor costs. You may have to resort to the help of 1-2 friends, acquaintances, 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 excavated pit, third-party assistance will be needed. Despite the small weight of the structure, do not forget about the dimensions. Alone with such a hulk will be hard to handle.

Installing a homemade septic tank

To install an improvised septic tank, you can't do without helpers - the design is voluminous, although not heavy. One such cube weighs an average of 60 kg.

Secondly, this solution to the local sewage issue will be successful only if it is properly installed. Otherwise, the septic tank may be wrinkled after a couple of months-year under the influence of environmental factors. All efforts and funds spent on the project will be in vain.

Thirdly, it should be borne in mind that additional cleaning will definitely be needed - after all, a septic tank from eurocubes is capable of 50-60% cleaning of drains. The water leaving it must necessarily pass through another filter.

This should be considered at the design stage in order to calculate everything correctly. For example, for the arrangement of filtration fields, a decent area will be required.

Eurocub septic tank scheme

It is important to immediately decide which post-treatment option will be equipped - filtration fields, an absorption well or an infiltrator

Assembly technology and installation

Often, homeowners, wanting to save as much as possible on the arrangement of sewage, think about how you can make a homemade septic tank of eurocubes.

This option looks very attractive financially, which allows it to look favorably against the background of expensive factory settings. And if you do everything yourself, without ordering the project "turnkey", the savings will be substantial.

Step # 1 - Design and Calculations

The decision to equip a local sewage system using so-called “flasks” or eurocubes is quite common. Some gardeners are enthusiastic about this option, calling it successful, profitable and effective.

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

Eurocubes for non-food products

Under the septic tank use eurocubes for non-food products. Moreover, you can buy a used container that has not been cleaned - it will not be displayed on the wastewater treatment in any way.

Both supporters and their opponents are right in this dispute. In fact, these containers can successfully perform the role of a septic tank only if properly installed. It is important to consider the type of soil in a particular area. If you ignore this point, then the capacity just squeezes and you have to start all over again.

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

It’s 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 is to be multiplied by 3. It is this volume that will have a septic tank - it should contain drains within 3 days.

Having decided on the volume of the tank, you have to choose the optimal place for its placement. Here it is necessary to take into account that the pipes to the septic tank and from it go in a straight line, without bends. Otherwise, clogging will often occur, which will have to be fixed.

Septic tank placement scheme

It is important to adhere to generally accepted standards for the removal of septic tanks from drinking water wells, the foundation of a house and water bodies.

First you have to dig a trench for laying the supply pipeline, through which sewage will flow into the first tank - the receiving tank. Then you need to dig a pit under the septic tank, given its size and adding to them an additional 15-20 cm on the sides for proper installation.

The depth of laying the pipes connected to the sewage 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 cleaning of effluent from the septic tank. After all, they will be cleaned by 50-60%, which is extremely small for safe diversion to the nearest reservoir or to the relief.

Fluid to undergo additional treatment:

  • in the filtering well;
  • on the fields of filtration;
  • on filter barrows (embankments).

One of these options is most often used. Therefore, it is important to immediately provide a place for the equipment of the additional filtration zone.

The next stage is the conversion of the Eurocup into a septic tank. For these purposes, it is necessary to modify it a little, using pipes, tees and consumables. Capacity itself is sealed, wall thickness from 1.5 to 2 mm. It is made of polyethylene, capable of withstanding caustic substances and acids, without reacting with them and without being destroyed.

Eurocube is a flask

The Eurocube is a flask encased in a rigid metal frame. On top of her hole for filling with the substance, and below - a valve for the extraction of this substance.

When converting a flask to a septic tank, it is necessary to hermetically seal the discharge point to avoid leakage of sewage into the soil. The same should be done with the second, third cube, if the future septic tank will consist of more than one chamber. Most often, home craftsmen use 2 or 3 Euro cups. Variants with 1st and more than 3 are rare.

For septic tanks buy containers designed for non-food products. And you can save a lot by opting for a used unwashed flask. It is easy to clean it with water, and complex contamination will not affect the efficiency of the future septic tank.

It is necessary to consider the norms for connecting the sewer pipe. This is 20 cm below the top of the tank. Next to be placed inside the tank 2 tee, cutting for this hole of sufficient size. Subsequently, the holes will have to be carefully welded and covered with a layer of waterproofing.

You can cut holes in the Euro tube with a grinder

When making cuts in the Euro Cup, you can use a grinder or other tool - the material is well cut

To the first tee the inlet pipe and the pipe going upwards are horizontally connected. It will be used for cleaning and revision. A pipe will be attached to the second tee to connect the 1st tank to the second and a smaller diameter pipe for ventilation.

All pipes are securely interconnected.

All pipes are securely interconnected and their sealing is performed. Moreover, it is better to use plastic pipes, they are durable

Moreover, the outlet from the first flask, through which it will connect to the 2nd, must be lower than the inlet. All joints and openings are sealed to prevent leakage.

Silicone sealant can be used for sealing.

Silicone sealant, epoxy resin can be used for sealing.

As for the second tank and the subsequent ones, if they are provided for by the project, each of them should be located 20 cm below the previous one. Based on this, it is necessary to cut all the holes.

Their number is the same as for the first flask. Only the outlet in the last European cup will be connected to the pipe that leads the cleaned drains to the filtration fields. It is advisable to provide it check valve.

Eurocubes welded to each other

It will be necessary only to rigidly connect all containers with each other, by welding metal rods to the frame. It is important that the construction does not collapse, otherwise all the pipes connecting the compartments to each other will tear.

Step # 2 - Installation and Installation

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

Here, the type of soil matters - in case of clayey, mobile soils, it is important to compact the bottom as best as possible by constructing a sand and gravel pad. A concrete screed should be made on top of it, so that the bottom probably would not deform under the weight of filled flasks.

2nd container is shifted 20 cm below the first

It is necessary to take into account when pouring a concrete screed that the pit should have a stepped bottom, because each subsequent container is shifted 20 cm below the previous one.

Then it is necessary to lower a septic tank in a ditch. It is advisable to make its anchoring, to further fix in place and protect against ascent. Now it is necessary to connect the incoming and outgoing pipelines to the septic equipment.

Pipes are laid with a slope

The pipes are laid with a slope in the direction of the septic tank 2 cm per 1 m length. Moreover, the outgoing pipe with the purified liquid is placed under an inclination to the filtration field. The pipeline section laid above the depth of soil freezing in the region is desirable to warm.

The walls of the septic tank and the pipeline will need to be warmed. To do this, you can take the foam or other material. It remains to fill the cleaning equipment, collected with his own hands, with water and cover it with sand.

Foam insulation

Between the walls of the pit and the septic tank, as well as the top to carefully lay the foam or other insulation

With a high level of groundwater, Eurocube walls will have to be further protected by pouring concrete. To do this, in the gap between the tank and the wall of the pit excavate reinforcement or boards and carefully distribute the concrete. If everything is done consistently, not forgetting to fill the septic tank with water, then the walls are not deformed.

Digging a pit with a septic tank

To prevent extrusion of heaving soils and damage to the hull, backfilling of walls can only be done with sand, carefully tamping

Concreting the upper part of the pit or not depends on the terrain. Pipes protruding above the surface must be protected so that nothing extra can fall through the septic tank.

To perform the ground treatment of effluents that have been treated in a septic tank, it is necessary to make one of the following structures:

Absorption well after septic tank

In smaller areas, it is better to arrange the ground treatment system in the form of an absorbing well. It should be remembered that its construction is possible only in sandy soils, the second condition is that the distance between the bottom of the well and the groundwater table is at least one meter.

Group of infiltrators for purification

If the free space on the site allows, you can install a group of infiltrators - plastic cassettes that carry out the ground after-treatment of wastewater treated in a septic tank

Construction of a filtration field

Similar conditions are required for the device filtration fields constructed from perforated pipes - drains laid on the filter bed.

Construction of a drainage ditch

One of the horizontal variants of the after-cleaning system is a drainage ditch. In all cases, between the lower edge of the device and the groundwater there should be a soil thickness of at least 1 meter

Step # 3 - further maintenance

In a private household each cog requires periodic attention of the owner. Local sewage also no exception.

A self-mounted septic tank will last for a long time only subject to periodic inspections and maintenance. To this end, special large-diameter pipes were installed at the installation stage.

Large diameter pipes

The large diameter of the pipes, mounted in a homemade septic tank, is useful for visual inspection, removal of insoluble substances and pumping sediment

On the surface of the effluent in the first chamber in 2, 3 or more chamber septic tanks fatty substances, pieces of polyethylene and other light substances that have fallen into the sewage float.

Periodically, the layer that does not give in to decomposition is to be removed mechanically. The frequency of such manipulations depends on the intensity of use of a septic tank and its careful attitude to it.

Also in the autumn should check the amount of solid deposits at the bottom of each tank. If there is a large enough cluster, they will have to call the aspensor machine or independently pump it out with a fecal pump. Such a sediment can be dumped into a compost pit for further use as an organic fertilizer.

Every spring it is necessary to check how the septic tank survived the winter. Especially if no one lived at the dacha during this period. In the event of damage to the container, it is necessary to immediately repair or replace it.

Do not allow sewage to start with a faulty septic tank - sewage can get into the groundwater, which will harm the environment.

Eurocubes can crumple

If the loess and peat were not selected on the site before the tanks were installed, and the septic tank was not concreted, then in the spring the Eurocubes can crush and it is necessary to dig it out urgently

To speed up the decomposition of organic waste, you can fill in special bacteria for septic tanks. But with regular filling of the tank with drains, there is no special need for this. Microorganisms that feed on organic matter multiply massively and process everything that comes in without external intervention.

Pluses and minuses of a septic tank from eurocubes

The self-made septic tank made of one or several eurocubs has a number of positive and negative sides. It can be a convenient and economical option for private home ownership, deciding the issue of arrangement autonomous sewage for bath or all objects on the site.

Disadvantages of a cleaning system

It should be noted that the independent assembly and installation of cleaning equipment from Eurocubes will take more than one day. But, if all the work will be carried out correctly and in full, the result will please every zealous owner.

The following most significant disadvantages of this treatment plant can be identified:

  • large front of heavy work;
  • strict installation rules;
  • the need for periodic maintenance;
  • short term operation.

If earthworks are not frightening and there is no desire to invite assistants, then you can cope with digging the pit and trenches alone in a week or two. Everything will depend on the duration of the work day of the home master - the work is simple, but hard in the physical plane.

Installation of a septic tank and laying of the pipeline

In addition to mounting the septic tank and laying the pipeline, there is still a need to equip the filtration fields. And this is additional work and investment.

As for the rigid rules, their non-observance will lead to the fact that the septic tank will somnet and all the work will have to be carried out anew, except for digging trenches for pipelines. And about this scenario, you can read a lot of reviews on the network.

In an effort to quickly equip the sewers in private ownership and sacrificing the quality of work, the owners got a very unsatisfactory result.

If you want to do everything quickly with a minimum investment of time and effort, it is easier to buy ready-made biological treatment equipment with installation specialists. It will be cheaper than two or three times to spend money on the construction of a septic tank from scrap materials.

Self-made construction, like many other types of arrangement of sewage, will require periodic maintenance. Indeed, in the container in the upper layer will accumulate insoluble substances in the form of fat, randomly washed plastic bags and other items.

Such waste will have to be caught from the surface, and solid silt deposits will need to be removed from the bottom.

The wastewater treatment plant, assembled from eurocubes, is able to process wastewater for at least 10 years. Moreover, its service life will directly depend on the type of material used in the installation of containers.

Broken faucet is not a hindrance to the septic tank

A small defect in the form of a broken crane will make it cheaper to buy a used container. This breakdown does not interfere with the device of the septic tank - it is still necessary to seal the drain hole

If a frame was made around of boards not pre-saturated with special protective composition, then such a structure would rot very quickly. In the future, it is necessary to dig everything out and carry out additional work - after all, the Eurocup, simply buried in the area, cannot serve as a septic tank.

In order not to crush it, you need to perform a number of activities, depending on the type of soil and its mobility.

The merits of a homemade septic tank

The self-made equipment made of eurocubes, is capable to become a reliable part of sewer system in the conditions of a country house / cottage.

It has a number of positive qualities:

  • simple and inexpensive components;
  • ease of preparation of the tank;
  • reliable sewage treatment;
  • the ability to install additional sections;
  • system assembly does not require special knowledge and skills;
  • full energy independence.

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

Euro tube flasks are sealed

Eurocube flasks are absolutely sealed - they, despite the thin walls, do not let the fluid in both outside and inside. This gives them an additional advantage for use in areas with high GWL.

Relatively low price of containers, especially if they are used, plastic pipes, cuffs, tees, other components and consumables allow you to build an inexpensive septic tank. It attracts hardworking homeowners with skillful and hands.

The undoubted advantage is the possibility at any time to add one or two additional sections, i.e. increase total volume. To do this, at the design stage, it is necessary to install a spare pipe, closing the hole tightly. You should also choose the place of installation so that additional sections, if such a need arises, fit on the site.

If these conditions are met, then when we are going to connect additional capacity, we will only have to dig a pit for it and prepare it accordingly. Further it will be necessary only to connect the new Eurocube with the already installed in a single system, using for this purpose the previously installed and suspended pipe exits.

Connection of two tanks

The connection of two containers is quite simple - the outgoing branch pipe is first connected to the incoming second flask. The joint is hermetically sealed.

Plastic container, made of dense material, can last for a long time. But due to the absence of stiffeners and the presence of an external metal grill protecting it from being squeezed, various scenarios are possible. Such a septic tank will be afraid of corrosion - if the frame collapses, the plastic container will quickly hesitate.

Instead of Eurocubs, you can use ready-made plastic containerHowever, its purchase will increase the costs allocated for the construction of the system.

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

The very same polyethylene capacity can last more than a decade, if you do not drain into the sewer substances that can destroy plastic - chlorine, fluorine, 50% solution of nitric acid.
