How to independently make a septic tank for draining waste from a bath? A septic tank for a bath (the situation is non-standard, experienced minds are urgently needed) How to correctly calculate the volume of a septic tank

A competent sewerage device is the key to convenient and comfortable operation of the bath. After all, you can truly enjoy the cleansing of the soul and body only if the process of washing is not overshadowed by extraneous irritants - unpleasant odors, water collecting on the floor and dirt in the room. How to equip the sewer for a bath, read in our material. In this article, we will talk in detail about common device sewerage in the bath, organization of water drainage, drainage, installation of a septic tank and other options.

Bath sewerage device

It is important to think about the arrangement of the sewer system of the bath even at the stage of laying the foundation, then the type of sewerage will be selected correctly, and all work will be performed with the highest quality and in a timely manner. Before arranging a sewer for a bath, you need to carefully study some points in order to choose the right type of sewage system:


  • the maximum number of visitors (it depends on what type of sewerage is suitable for a particular bath and what volume of the tank to choose);
  • seasonality of use of the bath - winter, summer or all year round;
  • joint sewerage for the entire site or arrangement of a separate sewage system for a bath;
  • the presence of a toilet in the bath building;
  • soil type;
  • soil freezing;
  • groundwater level.

After studying all the features of the site and implementing necessary calculations, you can consider what type of sewer system is suitable for your bath - a simple drain design, a sewage (drain) pit, drainage system or a large and complex septic tank.

Important. Regardless of which type of sewer system you choose, a well-thought-out scheme for the disposal of used water helps to solve most of the problems. Make sure everyone sewer pipes leading from the steam room and shower room were installed before the floors were laid.

How to make a drain in the bath

If you plan to build a seasonal bath without a toilet, then the best option is the simplest drain system (drain), which provides for the laying of sewers with a slope towards the storage tank. To do this, at some distance from the bath building (optimally - 2-3 m), put a storage tank and bring a sewer to it. As storage tank any reliable reservoir can serve - a can, a bath, a barrel made of plastic or metal, the main thing is that it has a suitable volume. After settling in a container, water can be used for watering flower beds and garden beds or for household work.

Important: you can calculate the volume of the storage tank, given that about 30 liters of water is required to wash two people. Thus, if the bath is designed for 4-6 visitors, you need to select a tank with a volume of at least 100 liters.

drain hole

Another option is an ordinary drain pit, however, such sewage can be arranged in those areas where ground water on the site lie quite deep. Otherwise, the drain pit will be filled with underground water and there will be little room for water from the bath.

How to make a drain hole

Calculate the volume of water that will be consumed in one wash, and dig a pit at a distance of three to four meters from the building, the dimensions of which will correspond to the approximate volume of wastewater. Drain hole for big bath usually made with a height, width and depth of 1 meter.

If the soil is sandy, then the sides of the pit must be strengthened, otherwise the earth will settle, crumble and disrupt the structure. The walls are reinforced with boards or slate, lined with bricks or concrete rings are installed, and in some cases tires are used. You can even pour cement, after making the formwork. Loam and sandstone can not be strengthened - water will quietly seep into the soil through the walls and bottom of the pit.

Drainage sewer system

Usually a bath personal plot is built for a limited number of people, not exceeding 6-8 people. Therefore, the most suitable option for your own bath will be the simplest drainage system.

To start on the site, select comfortable spot near the bathhouse for a drainage well. The depth of the well is calculated depending on the freezing of the soil in winter period. If the ground freezes up to 70 cm, then the well must have a depth of at least 1.5 m.

A drainage well is made according to the principle of the device drain pit- dig a hole of the required size and lay sewers to it. The main difference is the filling of the well with drainage, which is used as gravel, expanded clay, crushed stone or broken brick. So, the order of work on the device of a drainage well:

  • Put a 10-centimeter layer of clay on the bottom of the pit.
  • With the same 10 cm layer of clay, cover the trench that will be used as a drain, and give it the shape of a gutter. If, when digging a trench, a slight slope towards the sewer pit is provided, the water will flow down the gutter without lingering and not accumulating in one place.
  • 0.5 m of drainage is laid out on a carefully processed clay pillow (expanded clay, crushed stone or gravel mixed with sand), then carefully sprinkled with a layer of earth and carefully tamped.
  • It is advisable to insulate the sewer pipe laid from the bathhouse to the pit so that the water does not freeze in winter.

If a mixture of gravel and sand was used as drainage, then you need to remember that it quickly becomes dirty, and it will need to be cleaned periodically.

Bath septic tank

For a large bath with a toilet and a rest room, a simple drain pit will obviously not be enough, so a good owner needs to arrange a reliable sewer system - a complex and solid septic tank for a bath. If funds allow, then a septic tank can be bought - there are modern installations any size and difficulty level. But even the most complex treatment plant can be built with my own hands, therefore, usually site owners prefer to deal with the installation of septic tanks on their own.

Eurocubes for a septic tank

For the device of home-made septic tanks, Eurocubes are often used - plastic containers with a volume of a thousand liters.

Eurocube is a tank with a rigid steel crate designed for the transportation and storage of bulk and liquid cargo. Eurocubes are made from polyurethane, plastic, wood, high carbon steel and aluminum. In the upper part, the container is equipped with a neck with a polyethylene lid and a sealing ring, and in the lower part there is a drain cock with a valve and a seal.

In order for the eurocube to perform its functions qualitatively, it must be prepared:

  1. A tee is installed in the neck located in the upper part of the cube.
  2. At the end of the tank, at a distance of 25 cm from the top of the tank, make a hole for the inlet supply pipe.
  3. A hole is cut out in the upper horizontal part for the ventilation pipe, which is then connected to the tee.
  4. If two tanks are installed, they must be connected. To do this, make a hole for the connecting pipes. In the first container, a hole is cut 20 cm below the supply pipe. The second tank is located below the first.
  5. After preparation, the containers are connected to each other with pipes and fixed with fittings.
  6. In the second tank, 30 cm below the upper edge, a hole is made for the outlet pipe.

Important: if the neck is too narrow and it is not possible to insert a tee into it, an incision can be made around it. After installing the tee, seal it securely.

Carefully lubricate all joints of the structure with sealant, and then proceed to prepare the pit.

First of all, you need to correctly calculate the size of the pit. The pit should be such that about 15 cm remains between its walls and the walls of the container. free space, and a concrete slab 15 cm high fit at the bottom. Eurocubes will stand firmly and reliably if the walls and bottom of the pit are concreted.

Installation of tanks

After the concrete in the pit has dried, tanks are installed and filled with water. The gap between the tanks is concreted so that when the soil moves, there is no destruction of the structure. top the septic tank must be insulated by laying foam sheets on top. Then fill the tanks with earth, leaving only the ventilation pipes on the surface.

The arrangement of a septic tank has its advantages and disadvantages. Among the main advantages are the ability to collect a large amount of water in a storage tank, the absence of unpleasant odors and cleanliness of the area. The disadvantages of a septic tank include:

The need to equip the installation at the lowest site of the cottage in order to ensure the natural flow of water into the tanks;

Organization of free passage of the sewage truck to the site and directly to the sump;

The need to regularly order the services of vacuum cleaners, which creates an additional expense item in the family budget.

How to connect a bath to a central sewer line

Efforts to arrange sewerage can be facilitated by the presence of an autonomous or centralized sewerage. By connecting the drain pipes directly to the finished system, the owner gets rid of the problem of arranging the sewage system.


If the site is located next to the highway central sewerage, it is quite possible to connect to it. To do this, you need to write an application to the appropriate department, issue a package of permits and take some actions:

  1. Draw up a contract for installation and land works with a design organization that operates in full compliance with the law and has all the necessary certificates.
  2. If the work will be carried out near residential buildings, obtain the written consent of the neighbors to carry out the event.
  3. Install a special inspection well designed to control the sewer system and to check sewers.

Only after the implementation of all measures can a permit be obtained to connect the sewer system of the bath to the central highway.

Usually the owners small baths they try to equip the sewage system on their own, since the small amount of wastewater from the bath makes it inappropriate to spend all the time and effort on visiting institutions and drawing up contracts. The construction of a solid sewer system with your own hands will cost an order of magnitude cheaper and will not require much time.


We also recommend you: A septic tank for a bath can be done by hand.

The bath wastewater treatment device is sold in all construction stores. But their price starts from 6,000 rubles. The first appeared on sale at the end of 1980. Why are the baths built by our grandfathers still standing, and the drain system works perfectly? Just any design can be assembled with your own hands, a little skill and knowledge is enough. How to make a septic tank for a bath with your own hands, we will tell our readers about the design and installation in this article.

Features of the drain device in the bath

Scheme of the design of a septic tank for a bath of two wells.

Before planning the design of the drain in the bath, it is necessary to consider whether water will drain there or a toilet is provided in the design. It’s just that the drain from the bath, where there is no bathroom, is usually liquid and almost clean, so there is no need to make a complex structure. The main differences in the design of septic tanks with and without a bathroom.

  1. In a bath without a bathroom, there is no need to make a special filtration system in a septic tank. In the bath, only natural or soapy compositions are used, and their volume is several times less than that of plain water. You can simply install a well from rings without a bottom and the water itself will gradually go into the soil.
  2. For a bath with a toilet, you need to make a septic tank of two or more chambers. The first chamber is made under the accumulation of feces, it must be airtight, then filters are placed.

Thus, according to their design, do-it-yourself septic tanks for a bath are made into single-chamber and multi-chamber (more often than two). The size of a septic tank with a filter system must take into account the level of groundwater. If it is high, then it is necessary that the septic tank contains as much water from the drain as possible, otherwise in spring and autumn there will be problems with the system during the rains.

Given the GWL (groundwater level), with or without a bath toilet, choose the material for the septic tank:

  1. Barrels made of metal with a carved bottom.
  2. PVC barrels with drilled holes for water filtration.
  3. concrete rings.
  4. Monolithic concrete well from a single pipe.
  5. Well from old car tires.
  6. Septic tank made of large PVC containers.

The first two options are not suitable for soil with high level GW, since water will not leave them. It is advisable to install small PVC or metal barrels on sandstone.

The size and depth of the septic tank is selected individually. If the depth is large, then take a smaller diameter of the materials, and vice versa. The place under the septic tank must be available for pumping out the AC by a machine or a drainage pump with access to the public sewer.

How to make a septic tank from reinforced concrete rings

A septic tank for a bath made of reinforced concrete rings is not much different from a regular household one. Since the water from the bath is mostly clean, it is not necessary to make a large depth of the well. Before work, you need to decide on the place and purchase ready-made reinforced concrete rings from 2 pcs. Do-it-yourself work is carried out in the following stages:

  1. It digs two holes side by side in depth under 1-2 rings, the diameter is 20 cm larger than the rings.
  2. The first ring is installed. The bottom is filled with a concrete cushion by 10-15 cm.
  3. The second is mounted on it.
  4. Install pipes and cover for the well. If the cover is made of concrete, then it is necessary to leave a hatch in it. The first two rings will serve as a sump.
  5. In order for the seams between the rings to be airtight, they are coated with bitumen or mastic based on it.
  6. The first ring is mounted in the second well.
  7. The bottom is covered with a 15 cm gravel pillow.
  8. The second ring is installed, the seams do not need to be waterproofed.
  9. Between themselves, septic tanks are connected by a sewer PVC pipe, at an angle to the second well.

If the bath does not provide for the installation of a toilet, then only one well can be made from reinforced concrete rings with a bottom covered with gravel.

A system of reinforced concrete rings will last for many years, but there are disadvantages:

  1. It is difficult to carry out installation without the involvement of special equipment, since the rings are heavy.
  2. Price for rings from 2000 rubles. country bath with such a system is considered a luxury.

Summer residents and gardeners solved the problem with the price and heavy weight using improvised material, such as old tires.

How to make a septic tank from tires

Tires from a tractor or a large car economical option making a septic tank.

Old tires are taken from Kamaz or any other large car. You can find them for free at

The design of a septic tank made of tires is also made of two or one chamber, depending on whether there is a toilet in the bath or not. Installation is carried out in the following steps:

  1. They dig two or one hole with a depth below the freezing of the soil, at least 2 m. The diameter depends on the size of the tire (more than 15 cm of the wheel).
  2. Tires with inside pruned so that the well is less clogged. The cut is easier to make with a jigsaw or chainsaw.
  3. A well of tires is laid out on top of each other.
  4. A pipe with a diameter of 10 cm is brought to the well, they should be below the freezing of the soil, at an angle from the bath. A pipe is also mounted between the wells, at an angle from the first well to the second. The pipe is inserted into the slots on the side of the tires.
  5. The first well must be either concreted from below or laid a dense clay pillow. Gravel is poured at the bottom of the second.
  6. The space between the pit and the tires is covered with sand and gravel, carefully tamping.

For wells made of tires, it is necessary to come up with covers, and they will not only prevent the spread of odor, but also protect children and animals from falling inside.

Septic tank made of prefabricated iron or PVC cubes

Ready-made euro-cubes for the design of a septic tank for a bath.

PVC or iron cubes are sold in construction and gardening large shopping centers. They are expensive but easy to work with. The sewer well will be sealed. The volume can be any up to 10,000 cubic meters. PVC cubes are also called euro-containers, they are often used in large transport companies for the transport of various liquids. You can try to buy them there, used cheaper.

Euro-cubes are mounted in the following steps:

  1. The neck is cut and tees are mounted in it, all joints must be sealed with special plastic sealants.
  2. From the end of the container, stepping back from the top 250 mm, a cutout is made under plastic pipe required diameter.
  3. Another hole is made on top for mounting the ventilation pipe. It is connected to a tee.
  4. Further, if the design is two-chamber, connecting holes are made. In the first container, it should be 15-20 cm below the hole for the underwater pipe, in the second container, 20-25 cm below this hole.
  5. A wide hole is dug so that the entire structure fits (from 2 or 1 container).
  6. Cubes with pipes are installed at the bottom of the pit and reinforced with iron fittings or any old ones. metal pipes. If the septic tank is completely metal, then the fittings are welded by welding.
  7. The structure must be filled concrete mortar up the neck of wells.
  8. It is good to pre-insulate the system with foam plastic on the upper horizontal surfaces and only then concrete.

The design is eternal, but very expensive.

Septic tank for a garden or country bath

For small bath in the garden or in the country, you can make a single-chamber septic tank from a plastic or iron barrel without a bottom. To do this, holes are cut out in a plastic barrel along the entire perimeter of the walls and bottom, and the bottom is completely removed from the iron barrel. Further work is carried out as follows:

  1. A hole is dug in depth along the height of the barrel, the width is 10-15 cm larger than the diameter.
  2. Gravel 10 cm is poured into the pit, it is rammed.
  3. A hole is made on the side of the barrel, retreating 20 cm from above under the drain pipe.
  4. The barrel is installed in a pit, in order to avoid distortion, it is necessary to strengthen the structure with reinforcement from 4 sides simply by sticking it inside the pit.
  5. The distance between the walls and the pit is covered with gravel and rammed.
  6. From above, the well will protrude by 10 cm, you need to come up with a cover.

Water will gradually dissolve itself from the well into the ground, once a season it must be cleaned of debris.

More information about the septic tank for a bath can be viewed on the video:

It is not difficult to make a septic tank for a bath with your own hands, using any of the proposed methods. The most budgetary and affordable of car tires and old barrels, the material is light and installation can be done alone. Which option is more suitable for your bath should be chosen taking into account such factors as: the bath is used all year round or seasonally, is there a toilet in the bath or not, the groundwater level on the site and even landscape features. The above instructions will help you understand and perform the work correctly.

Bath septic tank: installation basics

In this article we will look at how to make a septic tank for a bath with your own hands.

Such a device will allow you to forget about overflow for a long time, and this will significantly save time and money. This design consists of two chambers with biological wastewater treatment. By installing it on the site, the owner will get rid of the pumping procedure for a long time.

How does a septic tank work without pumping

The choice of a septic tank for a bath is determined by the following conditions:

  1. The composition of the soil in the bath area.
  2. Terrain relief.
  3. Location from neighboring sites and water sources.
  4. Individual possibilities of the bath owner.


Such an installation consists of two tanks interconnected at the required level. In the main tank complex organic matter processed by microorganisms into non-hazardous waste for humans. In addition, heavy and solid particles of biological waste settle to the bottom.

Then the already purified water is poured into another container, after which it enters the soil through an additional filter from a layer of gravel and sand. In this way, the process of cleaning the sewage drain waters of the bath takes place, and the remaining liquid is removed from the structure through the second chamber. Such a septic tank without additional maintenance costs can work for a long time.



Pit for sewerage

The depth of the pit depends on the water level in the area. It will not work to build a deep structure with a close location of groundwater.

It's important to know!
The normal distance from a septic tank to a residential building should be from 5 to 10 meters to avoid washing away the foundation with sewage.

Before digging a pit, you need to find out what the composition of the soil is on the site. The average size of a septic tank should be about three meters deep and with the same diameter. But, as is known from practice, the larger the septic tank, the longer it takes to fill.

formwork

  • When the pit for the septic tank is dug, it is necessary to install the formwork for pouring the solution. To do this, you can use old wooden shields or boards.
  • It needs to be divided into two sections - one container can be made larger, and the other slightly smaller. A pipe for overflowing water must be inserted between them.
  • It is more convenient to make formwork directly in the pit. So that it does not fall apart under the huge weight of concrete, it needs to be strengthened. Spacers should be made of thicker beams to increase the rigidity of the structure.

It is advisable to install reinforcement or any other steel structures in the formwork to increase the reliability of the future septic tank. Sometimes old metal beds that have become unusable are used for this.

Filling formwork with concrete

Concrete is kneaded at the rate of:

  • 1 part cement;
  • 2 parts sand;
  • 2 parts gravel.

This solution must be filled with water and constantly stirred until a homogeneous mass is obtained. The solution must be not very thick and moderately liquid.

Tools and materials that we need:

  1. Concrete mixer.
  2. Shovel.
  3. Level.
  4. Brick.
  5. Wooden boards.
  6. Fittings.
  7. Metal hatches (2 pcs.).

An important point on how to build a septic tank for a bathhouse with your own hands is to fill it. The durability and strength of the entire structure depends on the quality of concrete. Pouring can be done immediately, or it can be done in stages, gradually raising the formwork higher along the solidification of the concrete mass.

If the concrete work is done with high quality, then in the near future the septic tank will not need to be repaired. And if you save on cement or do not carry out reinforcement, then in the near future you cannot avoid the repair procedure.

After the concrete hardens and dries, the construction of a partition between the chambers of the septic tank begins, which can be laid out from used bricks in order to save money.

Overlapping a septic tank

The final stage of work is the construction of the septic tank ceiling.

If there is a small finished slab or concrete cover, then it must be installed on the walls of the device. If the necessary materials are not at hand, then the floor slab can be made independently.

For this we will need:

  1. Make formwork from boards or other auxiliary materials.
  2. Install in it metal mesh from thick wire or fittings.
  3. Pour all this with a solution of concrete.

In this case, it will be necessary to build a hole for the ventilation pipe for the septic tank of the bath and create an inspection hatch to control the level of drains. Within 15 centimeters should be the thickness of the overlap. On this, the construction for a septic bath without pumping is completed.

Can be poured fertile land and plant flowers or shrubs that will close the sewer device and create an attractive view around your bath. And the price of such a device will cost you cheap.



What is our conclusion

From everything that we have considered above, a simple truth follows - a biological installation without pumping out can be built on their own. This small instruction help you without financial costs and the use of expensive building materials to build a septic tank on your site.

High-quality work on the installation of this device is the key to a long service life of the structure. The video in this article has prepared some more information for you, look!

How to make a septic tank for a bath or choose a ready one

The construction of a bathhouse in a summer cottage is simply impossible without organizing all the necessary communications, including sewerage. We will talk about how to build a septic tank for a bath in the country with our own hands in this article.


To make the operation of the bath as comfortable and long-term as possible, you need to take care of the outflow in advance. a large number dirty water. The construction of a cesspool is the most acceptable way out, since it will allow you to actively use the bathhouse without causing harm. environment without violating hygiene standards. In addition, a septic tank for a bath with a toilet is simply mandatory, because you can’t get by with a simple trench.

Choice principle

At the stage of planning the construction of a septic tank with your own hands, or the installation of factory fixtures, you should decide for what purposes it will be used, that is, what kind of drains will fall into it.

In most cases, when it comes to effluents from the bath, they mean "gray water", which contains soap suds, fatty acids, surfactants, as well as skin and hair particles.

But in cases where the bath is equipped with a toilet, the waste will be of a completely different nature. To dispose of such “black” sewage, a septic tank of a special design will be required, in which there are special filters and several settling chambers.

According to their structure, septic tanks can be both single-chamber and two-chamber. The simplest single-chamber septic tank is a design in which there is a large tank without a bottom, as well as drainage, that is, it works like a filter well. Can be used as a container metal barrels with a knocked out bottom, reinforced concrete rings, car tires in which small holes are made. The filter is a crushed stone pillow laid on the bottom of the pit.


It is worth noting that when placing a cesspool on the site, you should consider how high the groundwater lies on your site. If the water layer runs high enough, when calculating the size of the septic tank, it must be provided that as much water can fit in it at the same time as is usually obtained with the active use of the bath, otherwise it will quickly become overflowing.

If a toilet is provided during the construction of the bath, then the septic tank in this case must include at least two cameras. In addition, a similar option is relevant if regular and intensive use baths. A septic tank of this design is on sale in specialized stores.

And if you wish, you can build it yourself from well rings made of reinforced concrete, concrete mortar, car tires or eurocubes, that is, plastic tanks. When building a septic tank from well rings on your own, you will need to take into account a number of individual conditions and parameters of your site and bath.

In the first chamber, a rough mechanical treatment of wastewater is carried out. It is covered with a layer of fine-grained gravel or gravel, passing through which dirty water filtered out from large particles. And already in the next chamber there is a settling of water, which was subjected to primary rough cleaning.

The next container is a well through which water is gradually sucked into the ground. This design is provided for cases where you need a septic tank for a bath without pumping. In other cases general principle the operation of the septic tank will be similar, only the second chamber will serve and drainage well equipped with bottom filter.

We draw your attention to the fact that as the operation progresses, the gravel and crushed stone cushion in the first chamber gradually becomes clogged, as a result of which the speed of the primary mechanical cleaning. Therefore, this layer periodically needs to be completely replaced.

Types of septic tanks

Buy factory finished septic tank for sewage disposal - the simplest solution for suburban area. However, often a self-made cesspool copes with the task of cleaning and accumulating wastewater much better and more efficiently, and the construction of such a design will be much cheaper.


Cesspool with filter

A similar design consists of one chamber, the bottom of which is filled with 40-50 cm of a pillow, which includes sand, small pebbles and gravel.

The walls of such a well are laid out with bricks or rubble stone.

Design advantages:

  • requires little financial outlay;
  • produces high-quality wastewater treatment even with regular use;
  • is not difficult to build.


Flaws:

  • this type of drain pit is unacceptable for a bath with a toilet;
  • Drainage backfill silts up quite quickly, so it needs to be changed periodically.

Drainage pit made from car tires

Before you make a septic tank for a bath from car tires, they should be cut along the sides.

Chambers for a future septic tank should be dug about 2-3 meters from the bath. The recommended depth of the excavations is approximately 2-3 m, although the calculation is based on the expected amount of water used. The diameter of the pit should be 15 cm larger than the size of the tires so that they can be fixed.

In the first chamber of the septic tank, it is necessary to seal the bottom. For this, concrete mortar or clay is used. In the second chamber, a filtration cushion of gravel and sand is poured onto the bottom.

Car tires are laid on top of each other in prepared pits. Between themselves, they need to be fastened with wire, staples or plastic clamps.

In order to be able to bring a pipeline for wastewater and channels for transfusing them between the chambers, holes are cut in the tires.

For draining, a 110 mm pipe is used, which is connected to the first tank at a level below the soil freezing line.

The tanks are connected to each other by an overflow pipe.


The remaining gaps between the tires and the walls of the pits must be covered with previously excavated soil or clay.

From above, both chambers of the septic tank are covered with iron sheets or wooden shields. To disguise them, a layer of earth is poured on top.

The advantages of this type of septic tank:

  • using tires of various diameters, you can choose the diameter for a septic tank for a bath, which will be optimal in each individual case;
  • such a design does not require large expenses for materials and their delivery, and it is very simple to build it;
  • A tire septic tank is very convenient to use.

Flaws:

  • such structures do not provide a high level of tightness;
  • as a result, before the final suction, the wastewater is not subjected to sufficient quality cleaning.

Please note that the construction of a septic tank from car tires with one chamber equipped with a filtration cushion does not in any case involve placing a toilet in the bath.

Septic tank from eurocubes

The sequence of actions in the construction of a septic tank from eurocubes is as follows:

  1. In the purchased plastic eurocubes, with a capacity of about 1 m3, tees are installed in the neck part, and holes are also cut for communications.
  2. A pit is dug on the site, 15 cm wider than the Eurocube on each side, after which the containers are immersed in pits. By the way, septic tanks can be made from Eurocubes, which do not require sewage pumping.
  3. In the process of creating a septic tank, consisting of two chambers, the walls, as well as the bottom of the pit, must be concreted. To prevent fragile plastic containers from floating up, they are attached to concrete screed using special clamps.
  4. In the prepared pits, you need to install Eurocubes, which were previously filled with water. It will be possible to drain it only after the pit is completely backfilled. A concrete solution should be poured between the walls of the tanks and the pit, which will give the structure additional strength.
  5. So that the water inside the septic tank does not freeze, it is covered on top with a layer of foam and covered with earth. But the ventilation pipes must be on the surface.
  6. A sand-gravel mixture is poured into the previously dug trenches, in which drainage perforated pipes with a cross section of 50 mm are laid.


The advantages of the building:

  • due to this design, a very effective wastewater treatment is obtained;
  • Eurocubes provide long-term and reliable operation of the septic tank.

Flaws:

  • due to the need for preliminary concreting of the walls and the bottom of the pit, such a septic tank is quite laborious in execution.

Septic tank made of concrete rings

A cesspool made of reinforced concrete rings is very similar in design to a shallow well.

For its construction, as a rule, two pits are prepared.

At the same time, the depth of the septic tank and the number of required rings will be influenced by the level of the groundwater layer, as well as the estimated volume of the drained liquid.


In the first tank, the bottom is concreted to obtain an airtight chamber. The second tank at the bottom is covered with a sand and gravel layer, 20-30 cm thick.

At the final stage, communication pipes are brought into the wells and covers with hatches are mounted.

For a small volume of drains, you can build a single-chamber septic tank from concrete rings. In this case, its bottom is covered with gravel. A cesspool of plastic barrels will be built in the same way.

Industrial septic tanks

Those who do not want to bother with arranging a septic tank on their own prefer to purchase factory models of such products.

The following models are considered the most popular:

  • The septic tank "Triton" is presented in two versions - micro for 450 liters and mini for 750 liters. It is produced in single and double chamber, with a weight of 40 and 70 kg, respectively. The design is able to withstand up to -30 ºС. The kit comes with a cleaning system. The entire set, which also includes a lid with a neck, will cost consumers 12 and 21 thousand rubles, respectively.
  • Septic tanks of models DKS 15 and 15M are capable of processing up to 0.45 m3 of liquid per day. They are convenient to operate and maintain. Such products cost about 29-35 thousand rubles.

For deeper cleaning on the market, you can find stations of the Topas, Unilos and similar models. Such filtration systems already require more significant costs.


However, we note that for installation in the country, simple designs are best suited, in which sedimentation tanks and filters for coarse cleaning are equipped. If necessary, they can be supplemented with soil aftertreatment.

A septic tank for a bath can be done by hand.

A wastewater treatment device for a bath is sold in all hardware stores. But their price starts from 6,000 rubles. The first appeared on sale at the end of 1980. Why are the baths built by our grandfathers still standing, and the drain system works perfectly? Just any design can be assembled with your own hands, a little skill and knowledge is enough. How to make a septic tank for a bath with your own hands, we will tell our readers about the design and installation in this article.

Scheme of the design of a septic tank for a bath of two wells.

Before planning the design of the drain in the bath, it is necessary to consider whether water will drain there or a toilet is provided in the design. It’s just that the drain from the bath, where there is no bathroom, is usually liquid and almost clean, so there is no need to make a complex structure. The main differences in the design of septic tanks with and without a bathroom.

  1. In a bath without a bathroom, there is no need to make a special filtration system in a septic tank. In the bath, only natural or soapy compositions are used, and their volume is several times less than that of plain water. You can simply install a well from rings without a bottom and the water itself will gradually go into the soil.
  2. For a bath with a toilet, you need to make a septic tank of two or more chambers. The first chamber is made under the accumulation of feces, it must be airtight, then filters are placed.

Thus, according to their design, do-it-yourself septic tanks for a bath are made into single-chamber and multi-chamber (more often than two). The size of a septic tank with a filter system must take into account the level of groundwater. If it is high, then it is necessary that the septic tank contains as much water from the drain as possible, otherwise in spring and autumn there will be problems with the system during the rains.

Given the GWL (groundwater level), with or without a bath toilet, choose the material for the septic tank:

  1. Barrels made of metal with a carved bottom.
  2. PVC barrels with drilled holes for water filtration.
  3. concrete rings.
  4. Monolithic concrete well from a single pipe.
  5. Well from old car tires.
  6. Septic tank made of large PVC containers.

The first two options are not suitable for soil with a high level of HW, since water will not leave them. It is advisable to install small PVC or metal barrels on sandstone.

The size and depth of the septic tank is selected individually. If the depth is large, then take a smaller diameter of the materials, and vice versa. The place under the septic tank must be available for pumping out the AC by a machine or a drainage pump with access to the public sewer.

How to make a septic tank from reinforced concrete rings

A septic tank for a bath made of reinforced concrete rings is not much different from a regular household one. Since the water from the bath is mostly clean, it is not necessary to make a large depth of the well. Before work, you need to decide on the place and purchase ready-made reinforced concrete rings from 2 pcs. Do-it-yourself work is carried out in the following stages:

  1. It digs two holes side by side in depth under 1-2 rings, the diameter is 20 cm larger than the rings.
  2. The first ring is installed. The bottom is filled with a concrete cushion by 10-15 cm.
  3. The second is mounted on it.
  4. Install pipes and cover for the well. If the cover is made of concrete, then it is necessary to leave a hatch in it. The first two rings will serve as a sump.
  5. In order for the seams between the rings to be airtight, they are coated with bitumen or mastic based on it.
  6. The first ring is mounted in the second well.
  7. The bottom is covered with a 15 cm gravel pillow.
  8. The second ring is installed, the seams do not need to be waterproofed.
  9. Between themselves, septic tanks are connected by a PVC sewer pipe, at an angle to the second well.

If the bath does not provide for the installation of a toilet, then only one well can be made from reinforced concrete rings with a bottom covered with gravel.

A system of reinforced concrete rings will last for many years, but there are disadvantages:

  1. It is difficult to carry out installation without the involvement of special equipment, since the rings are heavy.
  2. Price for rings from 2000 rubles. A country bath with a similar system is considered a luxury.

Summer residents and gardeners solved the problem with the price and heavy weight using improvised material, such as old tires.

How to make a septic tank from tires

Tires from a tractor or a large car are the most economical option for making a septic tank.

Old tires are taken from Kamaz or any other large car. You can find them for free at

The design of a septic tank made of tires is also made of two or one chamber, depending on whether there is a toilet in the bath or not. Installation is carried out in the following steps:

  1. They dig two or one hole with a depth below the freezing of the soil, at least 2 m. The diameter depends on the size of the tire (more than 15 cm of the wheel).
  2. Tires on the inside are cut so that the well becomes less clogged. The cut is easier to make with a jigsaw or chainsaw.
  3. A well of tires is laid out on top of each other.
  4. A pipe with a diameter of 10 cm is brought to the well, they should be below the freezing of the soil, at an angle from the bath. A pipe is also mounted between the wells, at an angle from the first well to the second. The pipe is inserted into the slots on the side of the tires.
  5. The first well must be either concreted from below or laid a dense clay pillow. Gravel is poured at the bottom of the second.
  6. The space between the pit and the tires is covered with sand and gravel, carefully tamping.

For wells made of tires, it is necessary to come up with covers, and they will not only prevent the spread of odor, but also protect children and animals from falling inside.

Septic tank made of prefabricated iron or PVC cubes

Ready-made euro-cubes for the design of a septic tank for a bath.

PVC or iron cubes are sold in construction and gardening large shopping centers. They are expensive but easy to work with. The sewer well will be sealed. The volume can be any up to 10,000 cubic meters. PVC cubes are also called euro-containers, they are often used in large transport companies to transport various liquids. You can try to buy them there, used cheaper.

Euro-cubes are mounted in the following steps:

  1. The neck is cut and tees are mounted in it, all joints must be sealed with special plastic sealants.
  2. From the end of the container, stepping back from the top 250 mm, a cutout is made for a plastic pipe of the required diameter.
  3. Another hole is made on top for mounting the ventilation pipe. It is connected to a tee.
  4. Further, if the design is two-chamber, connecting holes are made. In the first container, it should be 15-20 cm below the hole for the underwater pipe, in the second container, 20-25 cm below this hole.
  5. A wide hole is dug so that the entire structure fits (from 2 or 1 container).
  6. Cubes with pipes are installed at the bottom of the pit and reinforced with iron fittings or any old metal pipes. If the septic tank is completely metal, then the fittings are welded by welding.
  7. The structure must be filled with concrete mortar along the neck of the wells.
  8. It is good to pre-insulate the system with foam plastic on the upper horizontal surfaces and only then concrete.

The design is eternal, but very expensive.

Septic tank for a garden or country bath

For a small bath in the garden or in the country, you can make a single-chamber septic tank from a plastic or iron barrel without a bottom. To do this, holes are cut out in a plastic barrel along the entire perimeter of the walls and bottom, and the bottom is completely removed from the iron barrel. Further work is carried out as follows:

  1. A hole is dug in depth along the height of the barrel, the width is 10-15 cm larger than the diameter.
  2. Gravel 10 cm is poured into the pit, it is rammed.
  3. A hole is made on the side of the barrel, retreating 20 cm from above under the drain pipe.
  4. The barrel is installed in a pit, in order to avoid distortion, it is necessary to strengthen the structure with reinforcement from 4 sides simply by sticking it inside the pit.
  5. The distance between the walls and the pit is covered with gravel and rammed.
  6. From above, the well will protrude by 10 cm, you need to come up with a cover.

Water will gradually dissolve itself from the well into the ground, once a season it must be cleaned of debris.

More information about the septic tank for a bath can be viewed on the video:

It is not difficult to make a septic tank for a bath with your own hands, using any of the proposed methods. The most budgetary and affordable of car tires and old barrels, the material is light and installation can be done alone. Which option is more suitable for your bath should be chosen taking into account such factors as: the bath is used all year round or seasonally, is there a toilet in the bath or not, the groundwater level on the site and even landscape features. The above instructions will help you understand and perform the work correctly.

If on suburban area available separately standing bath, then it is imperative to take care of the removal and disposal of the resulting effluents. An ordinary cesspool is not quite suitable for these purposes, especially if there is also a toilet in such a structure. High-quality cleaning of liquid waste can only be provided by septic tanks for a bath.

The choice of a septic tank for a bath

When buying an autonomous sewer system for bath and laundry complexes, showers or saunas, the following factors must be considered:

  1. The volume of wastewater sent to the treatment device. The septic tank must have sufficient capacity to process all incoming liquid waste. For these purposes, mini septic tanks with a small capacity are well suited.
  2. The presence or absence of a toilet in the bath. If there is no toilet, then only gray wastewater will come from the bath. Then you can install a simple treatment device, after passing through which, the effluents will be sent to additional soil treatment. Sometimes a septic tank is installed for a bath with a toilet; such equipment can perform deep biological treatment. Topas brand equipment is suitable for these purposes.
  3. Distance from the main residential building. If the bathhouse is located near housing, then you can install a single septic tank for the bathhouse and the house.
  4. Soil quality and groundwater level. The ability to create a filter field depends on these indicators. If the site is located on clay soil or a quicksand, it may be cheaper to buy and install a deep cleaning septic tank.

In most cases, to dispose of wastewater from a bath, it is enough to purchase a simple two-chamber septic tank without pumping. Thanks to a multi-level filtration system, high-quality cleaning of liquid waste is carried out.

Such devices are non-volatile and very easy to maintain. The price of a septic tank for a bath is usually below average. The best option is to buy a septic tank with a solid plastic container. Such products have sufficient strength and durability.

How to buy a septic tank for a bath

To buy a septic tank for a bath that performs high-quality wastewater treatment, it is better to contact specialists who have been selling and installing such equipment for a long time. There are many nuances that only professionals can know about. For example, it is imperative to carry out soil surveys to find out the possibility of creating a filtration field or a well for additional cleaning.

The company "Septic Topas Plus" provides an opportunity to profitably buy a durable and reliable cleaning device. Call or leave a request on the website to get detailed information about available models, terms of purchase, delivery and installation. Our specialist will come to the site free of charge to inspect and sign the contract, after which the installation will be completed within one day and a guarantee will be provided.

Local sewerage with its own treatment plant will allow you not to break away from civilization in settlements without basic infrastructure. If you make a septic tank with your own hands from barrels as an object of cleaning, the cost of improvement will be minimal. But for successful result technological subtleties are needed. Is it true?

To everyone who wants to acquire an autonomous sewage system on their own site, we offer useful information that thoroughly covers all aspects of its construction. The practical application of the information provided by us is a guarantee of a long service life and flawless operation of the system.

Presented to your attention interesting article introduces various constructive types of home-made septic tanks. It describes in detail the technology for constructing a wastewater treatment plant from waste barrels. Construction methods are illustrated with simplified graphics, photo and video applications.

Despite the fact that manufacturers offer enough a wide range, design and construction of home-made septic tanks (for example, from barrels), is quite relevant.

The option of a hand-held device is in demand for the following reasons:

  • the ability to reduce costs to a minimum by purchasing components, as they say, out of order - where it is cheaper, secondly, using the available improvised means;
  • installation of equipment can be carried out according to the so-called modular scheme, having previously calculated options for adding and complicating the system.

Let's say you equip the toilet first. In the future, connect a bathhouse, a sink in the kitchen, even a sink in the garage to the cleaning system. Of course, this will be easily feasible only if the "tie-in" points are prepared in advance - pipe outlets brought to the surface or close to it, reserved for a while.

The construction of a septic tank from barrels will allow minimal cost organize an autonomous sewage system with the disposal of neutralized and clarified effluents

Nobody better than the master who built the septic tank, does not know weak spots cleaning system and its capabilities. Although you should not make shortcomings, but only he will take them into account during operation.

It is no secret that manufacturers and sellers of any equipment, as a rule, do not inform buyers about the shortcomings, “sticking out” only the merits Self builder will know what can bring him down.

Knowing the approximate norms of water consumption by the family, taking into account the frequency of residence and the characteristics of the site around the house as a whole (type of soil and groundwater level), you can avoid both unnecessary effort and money, and “accidents” caused by poor cleaning system throughput.

A septic tank from barrels works on the principle of multi-section settling tanks, which, as a result of overflow and settling, ensure the separation of wastewater into water and sludge. After leaving the septic tank, clarified and purified up to 65% water is discharged into the ground, and sludge accumulates at the bottom of the septic tank until it is pumped out by sewers

You will learn the subtleties of the construction of a septic tank that works without odor emission and does not require pumping out from our other site.

Varieties of designs and schemes

A home-made septic tank constructed from barrels consists of several containers (chambers) installed in a given order. They are connected in series with each other by branch pipes so that the filling of the sections is carried out in a strictly defined order. This is achieved by installing cameras at different height levels.

The principle of operation of a multi-chamber septic tank is similar to the principle of operation. The entrance and exit of pipes into the chambers is done in such a way that water begins to flow into the next tank before the water level rises to the inlet pipe.

Gradually accumulating in the chamber, the water settles. The heaviest particles of pollution settle at the bottom of the tank, smaller and lighter ones continue their way through the system.

For free flow of sewage to the septic tank and from chamber to chamber, the sewer line is arranged with a slope. The slope must be observed at each site, including the sections between sections of the septic tank

In order for the methane formed during the processing of wastewater to be freely removed from the system, it is necessary to arrange ventilation. It is installed vertically at the exit from the house or at the exit of their last section of a homemade septic tank.

In addition, on the drain of water from plumbing fixtures, sinks, toilets, showers, etc., it is necessary to provide a siphon - at least made in the form of a “knee” - so that an unpleasant smell does not poison the existence.

The principle of operation of the septic tank is based on the gradual separation of solid insoluble components and the liquid component of wastewater. The more sections the sewer passes through, the higher the final degree of cleaning.

The most common is a three-section septic tank scheme used for processing gray and brown waste streams. However, if it is necessary to purify the contaminated water coming from the bath or kitchen, the use of one or two barrel sections will be enough.

Purified and clarified effluents from the septic tank flow into the soil post-treatment system, for example, it is disposed of through the filtration field

From the last barrel, they arrange an exit to the filtration field, which completes the cleaning process. This post-treatment system is an underground structure assembled from perforated pipes - drains.

The drainage pipeline is laid in trenches specially selected for them, lined with geotextile, on top of which pipes are laid and backfilled. Sand and gravel.

The function of ground aftertreatment of gray drains supplied by bathhouses, washing machines, kitchen drains, etc., can be safely entrusted to an absorption well built in the last barrel of the sewer system. In this case, the bottom is cut out from the tank, and it is filled with gravel and sand so that the layer of this backfill is at least 1 meter.


If the amount of runoff does not exceed 5–8 m³ / day, then a third section without a bottom, filled with a layer of 1 m of sand and gravel, can be used as a soil post-treatment system. Absorption (filtering) wells are arranged using this method.

As you can see, the scheme is quite simple, but its implementation in practice will require a lot of physical effort. Particularly time-consuming work is associated with the development of a pit for sections of a septic tank and trenches for a sewer pipeline.


The calculation of the volume of wastewater is based on the rate of wastewater discharge per person in l / day. A single-chamber septic tank is built with a sewage volume of up to 1 m³ / day, a two-chamber septic tank is built for 5 - 8 m³ / day

Construction of a septic tank from plastic barrels

Home-made treatment structures can be divided into groups according to the material from which the chambers are made, these are septic tanks:

The metal tank is more rigid. In addition, it is easier to fix it from floating up. But the main disadvantage of iron barrels is their poor ability to resist corrosion.

A septic tank made of concrete rings requires the use of special equipment during construction sewer wells. It is difficult to ensure the proper degree of tightness for a tire cleaning station if there is no experience with similar materials.

The use of plastic barrels in a septic tank allows you to do without lifting equipment and without welding

A homemade septic tank made of plastic barrels has more advantages:

  • light weight, which facilitates transportation, installation in the pit and assembly;
  • corrosion resistance. This moment is important not only in terms of reducing the hassle associated with replacing tanks, but also as an additional guarantee of cleanliness on the site;
  • the optimal way of construction, because installation of the system does not require electric welding;
  • tightness of tanks, due to which there is no need to carry out work on waterproofing the sewer facility;
  • manufacturability of the source material. Polymer containers are much easier to process with a cutting tool.

If necessary, slight cutting flaws can be easily corrected using cold welding tools.

Plastic barrels - the easiest to work, technologically advanced raw material for the construction of a homemade septic tank

Basic accommodation requirements

In the event that you have to obtain permission to install a septic tank in the regulatory authorities (SES, etc.), then carefully study SNiP No. 2.04.03-85. SNiP - "Building Norms and Rules" - a document similar to the standard (GOST), and it is this one that establishes the basic rules for the construction of external sewerage networks and treatment facilities.

Sanitary requirements regulates SanPiN - Sanitary Rules and Norma.

In any case, adhere to the following requirements for distances from the septic tank to the following objects:

  • the foundation of the house is 4-5 meters;
  • well, well - 30-50 m;
  • lake, pond - 30 m;
  • bushes, trees - 2-4 m;
  • road - 5 m.

Before device autonomous septic tank or its location must be discussed with the owners of neighboring plots. Although the standards provide for a distance from their fence to a septic tank of 2 m, the owners of a nearby estate may not be satisfied with the proximity of the sewer structure.

When deepening the bottom of the structure below 5 m, it will be necessary to obtain building permits from the local administration.

The greater the volume of wastewater processed in the septic tank, the farther it must be removed from the foundation

But even if permission is not required, consider the features of the site. It is pointless to arrange sewerage with systems of soil post-treatment in clay soils that do not have the necessary filtration properties.

The lack of ability to pass water will be “telled” by the stagnation of flood waters during the melting of snow and during periods of heavy rainfall. This means that clayey soils predominate in the section, which do not allow water to pass through and into itself.

On clay soils, sandy loams, clays, loams, storage tanks are installed. Make them plastic containers or groups of barrels. Accumulators only accumulate waste masses for pumping out by vacuum trucks, and do not process them.

A similar decision should be made if the groundwater level is close to the surface. Soils saturated with water will also prevent the disposal of the purified and clarified liquid component of wastewater.

If the section of the site is composed of clay soils that are unable to absorb purified water, the idea of ​​\u200b\u200bconstructing a septic tank will have to be abandoned

Instead of storage capacity station can be installed biological treatment. It purifies effluents by 98%, which allows them to be dumped onto the terrain.

Features and design standards

Having solid experience in the construction of such systems, all the required calculations can be made "by eye". But making up detailed plan and the development of a project, even in the form of a sketch, can be of great benefit.

Firstly, having determined the installation locations of the cameras and laying the highway, you will accurately calculate how much and what materials you need to purchase. If time endures, then before you start work, part of the necessary, it is quite possible, can be obtained for free.

And legally - people, as a rule, easily part with things that they consider trash. It has been proven more than once in practice that even a car can be assembled by spending money comparable to the price of, say, a new bicycle.

Secondly, the careful execution of the sketch contributes to the adoption of new decisions, as well as discipline. In addition, a well-drawn to scale drawing can reveal flaws in the original design and save you from unnecessary expense. It may well turn out that the scheme can be simplified by discarding the excess.

As you plan, keep the following in mind:

  • even if you do not need official permission to install a septic tank, try not to disturb the ecology of the site;
  • the sections of the septic tank should be located so that there is at least 5 m between them and the foundation - a distance that excludes soil erosion in case of emergency flooding of the septic tank and the occurrence of leaks;
  • the route of sewer pipes must be designed so that it is, if possible, without turns that contribute to clogging of the pipeline;
  • the external line of an autonomous sewer must be provided with a manhole for inspection and cleaning.
  • for every 25 m of the sewer line, an additional manhole should be built.

If the site is not happy with the dimensions, and the choice of location is a decided matter, then, if necessary, strengthen the walls of the pit.

To the level of seasonal freezing of soils, a septic tank and sewer pipeline it must be insulated so that ice plugs do not form in it

If it is planned to erect buildings in the future, the operation of which will require the use of water (a bathhouse, a sink, some kind of handicraft), provide for places for “tie-in” of water effluents from them into the treatment system. Moreover, the discharge of water from the bath can be taken immediately to the last chamber of the septic tank, since in waste water there will be no large particles of dirt.

If you do not intend to use the services of a vacuum truck, do not make the first chamber too voluminous - so that it can be easily cleaned manually. In addition, consider either the possibility of easy dismantling of the camera, or access to its contents for quick cleaning.

For maintenance, control of work and periodic extraction of sludge, the septic tank must be equipped with a hatch. It must rise above ground level by at least 18 cm.

If, in accordance with the clay type of soil on the site, only the installation of a storage tank is possible, then the design should be carried out taking into account the provision of unhindered passage of sewage equipment.

Preparation of building materials for work

The main materials necessary for making a septic tank from barrels with your own hands include:

  • pipes for the highway with a diameter of 110 mm;
  • fittings, angles, etc., in the quantity corresponding to your project.
  • the barrels themselves, designed for septic tank chambers. Select their sizes with the calculation of the approximate water consumption in the house, based on direct observations.

It is advisable to use barrels with sufficiently thick walls so that the joints of the pipes with them are as rigid as possible - otherwise the seam may lose its tightness from mechanical stress.

To connect polymer parts, it is more convenient to use adhesives that must be compatible with the materials of barrels and pipes.

Work out in advance the issue related to the freezing of cameras at low temperatures. You can use the old village way - put wooden sticks in containers.

At the very least, the ice that expands when it freezes will squeeze the tree, which has “taken” part of the impact. Also help plastic bottles filled with sand.

But in any case, the thermal insulation of the barrels will not be superfluous - take care of purchasing available materials in the required quantity.

Also required auxiliary materials. You need to buy a sealant to seal the seams. For this purpose, do not use silicone, it will not last long, and even cover it with some kind of protective layer fail - no coating will hold on silicone.

The best option would be to use a car body sealant - it has good adhesion (sticking ability), mechanical strength, and it can be top-coated with paint, mastic, etc. Best Features has a polyurethane sealant, but it is quite expensive;

It is necessary to purchase cement, sand, rebar - for pouring bases for barrels. Sand should not be subject to any special requirements in terms of quality. Let it be with pebbles, it's not scary, the main thing is that it does not include lumps of loam and organic pollution.

As reinforcement, any steel bars are suitable. cook reinforcing mesh to nothing - just fasten the bars with wire.

If, during the development of the pit, soil with biological inclusions, lenses and layers of clay soil was extracted, then quarry or river sand will be required to fill the pit with a septic tank installed

It will require crushed stone, gravel, granulated slag or similar materials to backfill the bottom of the pit (pit) before pouring cement;

The plastic barrel is lightweight, and therefore, when the container is not filled, it can be “pushed” to the surface by groundwater. To avoid this, prepare metal hooks, threaded studs - something for which you can “anchor” the barrel.

It is appropriate to use commercially available threaded studs - it is convenient to make hooks from them, on the straight ends of which you can fix iron plates with two nuts that need to be “drowned” in cement.

Construction of a pit with a concrete slab

How you decide to make the main pit - manually or with the help of an excavator - decide for yourself. Calculate its area so that after installing the barrel in place it is convenient to ram the earth, which is filled into the gap between it and the wall of the pit. It is also possible to provide for the thermal insulation of the container - slag, foam, - in general, with what will be more accessible.

Before pouring a concrete slab at the bottom of the excavation, it is necessary to check whether its depth is sufficient. To do this, you can install one of the barrels in the pit and see if there is enough depth for a concrete base. If everything is in order, you can start filling the bottom of the pit with cement. It is not necessary at the same time to make formwork, but it is advisable to fill it with sand and tamp the bottom before that.

If there is any doubt about the strength of the walls of the pit, then they must be strengthened with a board before pouring. Then it is enough to fill the bottom with a thin layer of liquid cement. After it dries, you can lay the reinforcement and fill it “cleanly” - with the alignment of the horizon. Do not forget about the embedded parts for anchoring barrels!

Mix cement with sand - 3 parts of sand to 1 part of cement. It is very convenient to use an electric concrete mixer, but acquiring one just for this job (unless there are plans to build something else) does not seem appropriate. It is enough to choose a suitable trough, convenient for working with a shovel.

Mix sand with cement first without water - on the contrary, avoiding its premature ingress, and then gradually adding liquid, bring the solution to the desired consistency. To prepare small portions of cement, you can also work on a sheet of iron or plywood - if there is no trough. Before directly filling the foundation, moisten the compacting backfill with water.

In order to anchor light plastic flooded septic tank concrete slab need to lay metal brackets

To level the fill, use a tool similar to a flat mop. While pressing the sole to the surface, level the solution with light translational movements. So, by the way, you will achieve a better filling of the future site with a solution.

To prevent cracking of the mortar when it dries, especially in hot weather, cover the flooded area thick cloth, after the cement "seizes", and pour water. For such a purpose better fit tarpaulin or similar synthetic fabric- here it is important not to wet the surface of the site, but to slow down the evaporation process.

Proceed with the installation of pipes when the barrels are installed, but not completely fixed. Only when the entire structure is assembled can its elements be fixed. It is advisable to fill the barrels with water - for stability.

All these points are important to take into account due to the fact that the final stage of the assembly will be the processing of the joints of pipes and barrels with sealant - while it dries, it is necessary to ensure the immobility of the structure.

Before applying the sealant, treat the places of its contact with plastic with coarse sandpaper (No. 80-100) - for better adhesion and durability of the seam. By the way, triangular scarves for rigidity can also be installed on the same sealant, 3-4 pieces per joint, between the barrel wall and the pipe. While the sealant is drying, wrap the scarves with wire, masking tape, etc. - so that they do not "slide".

After testing the system for water permeability, proceed to the final backfilling of trenches and pits. Compact the soil gradually, filling the ground in layers. You can throw stones, bricks, etc. into the gap for rigidity.

In those places where it is possible that equipment will run into the filled pipes and pits, before filling the surface layer of soil, make a protective flooring at least from boards.

Assembly and connection of the structure

So, all materials are ready. The next step is to cut holes in the barrels for pipes. There is no point in describing this procedure. The only thing that can be advised - do not immediately make holes in size - let the pipes be inserted with effort, cut off the excess if necessary.

Next, you should take care of fixing the pipes in advance, otherwise, when backfilling and tamping trenches and pits, the integrity of the seams can be violated. Pipes can be fixed using all the means at hand - wire, cutting boards, bricks, - whatever you like.

Before digging trenches and pits, it would be useful to assemble the entire structure, without fixing the details, to place everything on the ground. Pipes can simply be placed on the ground next to the barrels. This will help to more accurately make markings on the ground. Having marked the contours of the highway and pits with stakes and twine, you can start digging.

Visual step by step guide

The process of building a septic tank with overflow from used barrels will present a visual step-by-step instruction:

Image gallery

Before the construction of a home-made septic tank, a pit is being developed, the dimensions of which will ensure convenience in the performance of work

In the lids of both barrels, planned for the installation of a septic tank with an absorbing well, we cut a hole for the flange of the sewer pipe

We apply flanges to the holes cut in the barrels. Refine cuts if necessary.

We are still finalizing the barrel intended for the device of the absorbing well - in its upper part we cut out two holes for the introduction of drainage pipes

In the upper barrel, which will be used as a receiving chamber, we cut out only one hole. It should be directly opposite the one cut into the lid.

We install the first barrel on the compacted and leveled bottom of the pit. We connect the flange to the hole cut in the cover

To install a second barrel in front of the already installed first swarm, a recess

We fill the recess with gravel, which will perform the function of ground purification of the clarified water that has come out of the septic tank
