Do-it-yourself septic tank for a bathhouse. How to make a septic tank for a bath: from concrete rings, tires, barrels and Eurocubes. This design has such disadvantages as

Good day. Thank you for visiting the created topic. I hope you can advise.
SITUATION:
1. The goal is to make a sewer system for a bathhouse under construction.
2. The bathhouse will have the following sewerage points: a shower in the washroom, a toilet (toilet) in the washroom, a floor drain in the washroom (there will be a small barrel-font), a floor drain in the steam room (the steam room will have a washing function with basins) .
3. The bathhouse is one-story, small (40 sq. m.), frequency of use is once every 1-2 weeks. 1-3 people will go to the bathhouse, no more.
4. The site is extreme in the SNT; a small shallow (depth less than 1 m) river runs relatively close to the edge of the site (8-10 m).
5. GWL is high (when they dug holes for the piles for the foundation of the bathhouse, there was already water at a depth of 1 m). The soil is water-saturated sand and loam, gravel.
6. The foundation strip (and the floor of the bathhouse, respectively) are raised above the ground by 45 cm.
7. Sometimes it floods a little (the river doesn’t seem to overflow its banks, it’s just melting snow, the area is at the bottom of the slope).
8. The site is located on a sharp slope; no car will ever approach the bathhouse or the planned location for installing the septic tank. I plan to clean it once a year and invite a Tajik.
Attached is a proposed bathhouse sewer system with a 1-chamber septic tank consisting of 2 concrete rings without a bottom, with further discharge of liquid into a small filtration field.
QUESTIONS:
1. CRITICISM OF THE PROPOSED SCHEME IS VERY NEEDED. PLEASE REPLY WITHIN 1-2 DAYS, BECAUSE I AM LEAVING AND I NEED TO URGENTLY APPROVAL THE SCHEME FOR THE FOREIGNER SO THAT HE FURTHER LOOKS FOR A CONTRACTOR.
2. WHAT I ASK YOU TO PAY ATTENTION TO IN YOUR COMMENTS:
2.1. For the outlet from the washing room (toilet, shower, floor drain) I plan to use a pipe with a diameter of 110, for the outlet from the steam room a pipe with a diameter of 40, and the main pipe to the septic tank with a diameter of 110. Is that normal?
2.2. Which pipe would be optimal to choose (material, if possible, manufacturer)? I read that polypropylene seems to be better than PVC. Optimal in my understanding - it will work for a long time, without hemorrhoids, and you won’t overpay for unnecessary qualities.
2.3. The pipe will exit the bathhouse at a depth of 0.5 m, the pipe will enter the septic tank at a depth of 0.7 m, and in the filtration field it will arrive at a depth of 0.8 m. Is this normal?
2.4. Is it necessary to insulate the pipe? What is the best way to do this if necessary?
2.5. Should the pipes be laid and buried simply in the ground or should they be surrounded with crushed stone?
2.6. The septic tank ring will be 15 cm above ground level. Is it normal or higher?
2.7. I have provided ventilation pipes - one into the septic tank itself and the second I want to cut into a leaky pipe in the filtration field. Normal? Shouldn't the nearby gazebo stink?
2.8. Dimensions of the filtration field are 2 m by 1 m. Before the filtration field the pipe is coming without holes, there will be a gift in the filtering field. Normal?
2.9. What should be the design (layering of materials with thicknesses) in the filtration field? To prevent the holes from being clogged with high water, use geotextiles on top of the pipe.
2.10. It is normal to seal the joints of the rings with the following composition: 1 part cement, 1 part sand, 0.7 parts water, 0.7 parts liquid glass, then how will the mastic dry?
2.11. Rings better with mastic pass or stick waterproofing with a blowtorch? Is it better from inside or outside?
I WOULD BE VERY GRATEFUL IF YOU HELP WITH ADVICE AND EXPERIENCE. THANK YOU TO EVERYONE WHO CARE. THE WORLD IS NOT WITHOUT GOOD PEOPLE.

Many owners country houses Are you wondering if it is necessary to install a septic tank under the bathhouse? The answer is definitely necessary. This facility will allow for recycling and cleaning Wastewater. A septic tank is especially needed for a bathhouse with a toilet, because such wastewater requires high-quality, effective cleaning and recycling. Without this treatment plant the bathhouse will not be able to function properly. If you are not using a septic tank, but sewer well, then you will have to pump it out too often. In our article we will tell you how to properly install a septic tank under a bathhouse. And the video at the end of the article will help you understand the process more clearly.

Before thinking through the design of the future septic tank, you need to decide whether there will be a toilet in the bathhouse or not. The thing is that the wastewater from an ordinary bathhouse without a bathroom is liquid and almost pure, so in this case there is no need to make a complex structure.

The design of septic tanks for a bathhouse with and without a toilet is somewhat different:

In a garbage disposal facility without a toilet does not need to be provided in a septic tank special system filtration. In this case, it is enough to equip a well of concrete rings without a bottom on a layer of gravel and crushed stone, and the wastewater will filter into the soil itself.
Septic tank under a bathhouse with a toilet must be made in the form of a multi-chamber structure. The first sealed settling chamber is needed to collect feces, and the following compartments perform filtering functions.

The advantages of constructing septic tanks for homes and bathhouses from rings without a bottom include simplicity of design and speed of installation, the ability to save on materials, and the absence of the need for frequent cleaning. However, such a septic tank under the bathhouse does not guarantee High Quality wastewater treatment.

It’s worth knowing: septic tanks for homes and baths can be single-chamber or multi-chamber.

If you decide to make a septic tank for a bathhouse, then the choice of material for it depends on the standing level groundwater. A septic tank can be installed using the following types of materials:

Metal barrels without a bottom cannot be used in areas of high groundwater. It is better to choose this septic tank material for sandy soils.
Plastic barrels with holes for filtration. This option is also not suitable for high groundwater level(groundwater level). They can only be installed on sandstone.
You can make a simple septic tank from concrete rings.
Some types of septic tanks are made of monolithic reinforced concrete.
A small sump can be constructed from car tires.
Sometimes one or more PVC cubes are used to equip a treatment plant.

Important: the dimensions and depth of the septic tank for a house or bathhouse are selected individually. If the septic tank is not intended for use drain pump for pumping wastewater into general sewerage, then it is necessary to provide a place for the access of a sewage disposal truck.

Choosing a site for construction

If you decide to build a septic tank for a bathhouse with your own hands, then you should pay attention Special attention choosing a place for its installation. When choosing it, adhere to the following rules:

To facilitate connection to the sewer system, it is better to locate the septic tank close to the house.
From water sources located on the site, the treatment plant should be located at a distance of 20-25 m.
The septic tank should be located at a distance of 10-15 m from the residential building.
If the groundwater level on the site is high, then the choice of location should be approached with special care.
The septic tank under the bathhouse must be located in such a place that it can be easily accessed by vacuum cleaners.
The pipe leading from the bathhouse to the septic tank should not be connected to it at an angle of more than 120 degrees. Otherwise, problems may arise with connecting and laying the pipeline.

On clay soils and in areas with high level When groundwater is standing, filtration of wastewater from the bathhouse into the soil is impossible. In this case, other types of lead must be used. Suitable for these purposes storm drain or a body of water. You can also build a drainage ditch in the form of a tray with a concrete bottom. On sandy soils, it is advisable to install a filtration absorption well, because this type of soil quickly absorbs large volumes of water.

Treatment plant without pumping

A septic tank for a bathhouse without pumping can be used if you regularly use this structure (without a toilet), but you do not want to pump out wastewater frequently. In this case, water from the disposal facility will be drained into reservoirs, drains or other suitable places. It can also be collected in filtration wells, from where it will be filtered into the soil.

There are many options independent device such a treatment plant. In addition to them, you can use ready-made treatment plants. However, their price is rather high. Such designs are designed for different volumes of wastewater.

Principle of operation

As you already understand, to get more high-quality cleaning It is better to make drainage from a bathhouse with a toilet not one settling tank, but several filtration compartments. In each of them, the wastewater undergoes multi-stage purification, and at the output you will receive completely harmless purified water, which can be used for technical needs and watering the garden.

As a rule, to install a septic tank under a bathhouse with a toilet, a two-chamber design is required. In this case, both chambers are connected to each other by an overflow. The operating principle of such a structure is as follows:

The drainage from the bathhouse enters the first compartment of the structure through a pipeline. Here, the heavier and denser components of the wastewater settle to the bottom.
In addition, wastewater in the first chamber, where there is no oxygen, undergoes primary purification by anaerobic bacteria. These microorganisms live in conditions without access to oxygen, so such a chamber is suitable for them. favorable environment a habitat.
When the level of liquid waste in the first compartment reaches the overflow location mark, the water flows by gravity into the second compartment.
If the design of the second chamber does not provide a bottom, then the treated wastewater is filtered through a layer of gravel and crushed stone into the soil. If the septic tank under the bathhouse has a bottom in the second chamber, then the wastewater is discharged through special pipe into a filtration well or ditch.

It is worth noting that during the life of bacteria, wastewater decomposes into gas and water. As a result of the activity of anaerobic organisms, methane gas is formed, the removal of which requires ventilation duct. To populate a septic tank with special microorganisms, ready-made biological products are used.

Treatment facility made of reinforced concrete rings

To properly make a septic tank for a bathhouse from concrete rings, you do not need to dig too deep a pit. When performing work, adhere to the following sequence of actions:

Two holes are dug nearby to the size of the concrete rings. For such a small structure, 1-2 products are enough. In this case, the diameter of the pit should be 20 cm larger than the diameter of the ring.
After installing the first concrete product the bottom of the pit is filled with concrete to a height of 100-150 mm.
After this, the second ring is installed. To seal the seams between the rings, bitumen or bitumen mastic is used.
Now the sewer pipeline is being laid and the structure cover is being installed. In this case, a hole for a hatch must be provided in the lid. The first structure will serve as a settling tank.
Now we install the rings in the second pit.
We fill its bottom with a layer of crushed stone 150 mm thick.
There is no need to waterproof the seams in the second chamber.
The chambers are connected to each other via an overflow pipe. It should go at an angle from the first to the second chamber.
The second compartment is covered with a lid without a hatch.

Important: a septic tank under a bathhouse without a toilet can be made from one chamber, consisting of two concrete rings and a bottom covered with crushed stone.

Tire construction

It is very simple and inexpensive to make a septic tank for a bathhouse with your own hands from car tires. It can also be single-chamber or double-chamber, depending on the presence or absence of a toilet in the bathhouse. Installation is carried out in the following sequence:

They dig a pit at least 2 meters deep. Its diameter depends on the dimensions of the tire. It should be 15 cm larger.
Tires with inside cut a little so that after laying several elements on the inside there will be no such relief protrusions.
The tires are stacked on top of each other, forming a vertical well.
A pipeline with a cross-section of at least 100 mm is laid to the well. At the same time, it must pass below the soil freezing mark and go at a slope from the disposal facility to the well. If a two-chamber design is used, then an overflow pipe is installed between the two wells, running at an angle from the first to the second structure. To install the pipes, holes are cut in the side surface of the tires.
The bottom of the first well is concreted. And the bottom of the second structure is covered with rubble.
The gaps between the wells and the walls of the pit are filled with a mixture of crushed stone and sand, and then carefully compacted.
Wells must be covered with lids made of suitable material.

Septic tank made of PVC cubes

Quite quickly and cheaply you can make a septic tank under a bathhouse from Eurocubes. They are made of iron or PVC. The second option will be cheaper. Installation of cubes is carried out as follows:

The neck of the cube is cut to install a tee there. All joints are carefully sealed.
A hole is made on one side surface of the cube with a diameter equal to the cross-section of the supply pipe. This hole should be 25 cm from the top of the container.
On the top surface there is a hole for installing a ventilation pipe. It is attached to the tee.
After this, holes are made in the two-chamber septic tank for overflow. In the first cube it should be 150-200 mm below the hole through which wastewater enters the septic tank. And the hole for the overflow in the second cube should be 200-250 mm below this hole.
One pit is being dug for two cubes at once.
The bottom of the pit is concreted. Reinforcement outlets are made in it to fix the cubes.
To protect plastic containers from floating during floods, they are placed in reinforcement strapping and fixed to outlets at the bottom of the pit.
After insulation with polystyrene foam, the entire structure is filled with concrete up to the level of the neck of the cube.

These days, at the dacha, or personal plot there is a bathhouse. This is a health-improving and beneficial miracle for the body that has come down to us from the depths of centuries and is the inheritance of our ancestors. No other bathhouse or sauna can compare with the Russian bathhouse. The Russian bathhouse has many advantages, but there are also disadvantages, not in the bathhouse itself, of course, but in its operation, more precisely in the use of sewage systems. Often in old bathhouses there was simply no sewage system and the water went into the cracks between the boards in the floor and then into the soil.

Of course, the whole thing then exuded moisture and dampness for a long time. It was not uncommon for bathhouse owners to have to dismantle the floor in the steam room and subsequently dry the boards, or simply keep the door open until the next time to ventilate and dry out. In the bathhouse anyway high humidity, and if there is dampness coming from under the floor, the structure will quickly become unusable.

Also, during the operation of bathhouses without sewerage, the owners change them once every 10 years, for example. lower crown log house Some bathhouse attendants use a trick and make the lower crown from hard wood, such as oak.

In order for the bathhouse to serve the owners for a long time, it is necessary to install a sewer system. There's a huge selection these days sewer systems, septic tanks of all designs and sizes for houses and baths. But these septic tanks sometimes cost a lot of money and are beyond the means of a simple summer resident. What to do to the common man and how to protect the bathhouse from dampness and moisture? As always, you need to look for a solution and think with your head. So the author thought about it and came to the decision to make a sewer system with my own hands and save money family budget.

He took the principle of operation of a conventional septic tank as the idea. The septic tank is designed as follows - two tanks connected to each other in the upper part, when the first tank is filled, it begins to flow into another tank which performs the function of drainage. The author took the information and drawings from the Internet, thought it out and completed it to his own liking. So, what will the author need to fulfill his idea?

Materials: two plastic barrels, cement mortar, boards, gravel, polystyrene foam, sewer pipes.
Tools: shovel, hammer, axe, hacksaw.

Then he dug a hole for a homemade septic tank and took him out of the bathhouse sewer pipe and connected it to the tank. I made a lid on top.

That's all and covered the top with a lid.

If you decide to build a bathhouse, then it is important to think about making a septic tank - it is a necessity, because there will be a lot of wastewater in the bathhouse. In this article we will learn how to make a septic tank for a bathhouse with your own hands.

For proper arrangement A septic tank in a bathhouse, taking into account the type of soil and the location of groundwater, you can use two methods:

Storage drive installation. With this option, a large container is installed that will collect all the drainage from the bathhouse. As soon as the container is filled, it must be cleaned by calling a sewer truck. The advantage of such a septic tank is the simplicity of its design. You need to purchase a ready-made plastic container the right size and install it in the pit. As for the disadvantages, it is problematic in maintenance. If you use the bathhouse regularly, you will have to call a sewer truck regularly, which is not a cheap pleasure. Moreover, the installation of a septic tank in this case must be carried out in such a way that there is free access to it, which can be problematic.
Another method of arranging a septic tank for a bathhouse is to make a structure from which there will be no need to pump out wastewater. For this purpose, filtration wells are made or ground filtration is organized.

At the very beginning, all the dirty work needs to be done. It is important to consider the following nuances:

The depth of the septic tank must be sufficient so that when it is used in winter time he didn't freeze.

Cover the bottom of the first chamber with sand and place a layer of clay up to 200 mm. Then it can be concreted.

The second chamber is constructed with a drainage pad. To do this, pour a layer of 400 mm of crushed stone onto the bottom.

In order to slightly, but reduce the amount of land work, it is possible to provide insulation of the septic tank chambers and pipes. As a result, the depth of the hole will be slightly reduced.

If you purchased ready-made concrete rings, the work process is significantly accelerated:

Lifting equipment is usually used to install reinforced concrete rings. It will be very difficult to install them yourself, although in some cases this is only the only option, for example, when special equipment cannot drive up to the construction site of the septic tank.

It is recommended to connect each ring to each other. The joints are sealed with mortar, which increases the tightness of the structure.

An important and difficult step will be the installation of a pipe that will connect several chambers into one. It is important here to implement correct connection. So, the pipe with incoming waste should be as high as possible. The next pipe with an overflow into the next chamber below and so on.

You can buy reinforced concrete rings with ready-made holes. Designs with a finished bottom are also available for sale. This will save you from having to fill concrete platform in the hole. Rings with holes are sold for the drainage chamber.

Backfilling the septic tank

When all the rings are installed, all that remains is to make the final touch. To fill the rings with outside It is recommended to use clay. In case of leakage, the clay will serve as an additional sealing layer. Although some are covered with earth raised from the pit. It is important to compact the soil or clay thoroughly. This will create good strength of the entire structure, and the earth will not settle much after a while.

Following these simple tips, you can make a septic tank for a bathhouse with your own hands. Now let's look at another technology that involves the use of tires.

Septic tank made from tires

One of the economical methods of arranging a septic tank for a bathhouse is the use of car tires. To do this, you need to use the tires of a large car or even a tractor. The design of a septic tank made from car tires can also have two or three chambers. The number of cameras depends on the availability of a toilet in the bathhouse. So, the process of manufacturing such a structure is carried out in the following sequence:

First of all, pits are dug. The width depends on the diameter of the tires used. In this case, the width of the pit should be 150 mm wider so that you do not have any problems during installation. As for the depth, it should be below the freezing level of the soil.

Next, trim the edges from the inside of the tires. This is important so that during operation of the septic tank it does not become clogged. The cut will be easy to make using a chainsaw or jigsaw.

When all the tires are trimmed on the inside, they need to be laid out on top of each other in the pit.

Now it’s time to install a pipe to drain the wastewater from the bathhouse, as well as to overflow into the second chamber. It should be installed at the appropriate angle. To insert the pipe into the tire, you must also make an additional cut.

In the first chamber, the bottom is constructed using concreting or clay. The bottom of the second chamber is filled with coarse crushed stone.

When the tires are installed, the space between the pit is filled with sand or fine crushed stone. You can also use clay, as in the case of reinforced concrete rings.

When making a well from car tires, it is important to build a reliable lid that will prevent it from falling inside.

This method is quite simple. The hardest thing to do is earthworks, having dug two holes. Such a septic tank can be made in a few days.

PVC cubes for septic tank

Another simple option for arranging a well for a bathhouse is use of PVC cubes (also called Euro-containers). Although they are very expensive, their installation is very simple and quick.

To save money, you can buy used containers from transport companies who use them to transport various liquids.
Installation of PVC cubes is carried out as follows:

Cut off the neck of the container and install a tee in this place. The joint is treated with a special sealant for plastic.

You also make a second hole at the end of the container, 25 cm away from the top. The installation will be installed in this hole. plastic pipe, coming from the bathhouse. The same holes are made to connect the containers to each other if you are making a two-chamber septic tank. It is important to take into account the height difference at which the pipes will be installed.

Plus, you make another hole on top of the container to organize ventilation.

This entire structure can be made on the surface, and then, after digging a hole, carefully lower it.

It is recommended to reinforce the bottom of the pit with a screed using iron reinforcement. This also applies to external walls. A frame is also made and everything is filled with concrete right up to the neck.

Although the resulting design of a septic tank for a bathhouse turns out to be very expensive, it will serve you for decades.

If you have relatively small sauna on summer cottage or in the garden, then it makes no sense to equip the above-described septic tanks. You can use metal barrels. In this case, the work will look like this:

As in all cases, you dig a hole, with a margin of 150 mm in width. At the bottom you also make a cushion of crushed stone, 100 mm thick.

Stepping back 200 mm from the top of the barrel, make a hole for the drain pipe.

To prevent the barrel from warping during operation, stick reinforcement into the ground on four sides. They will hold the barrel during its installation.

As in other cases, fill the gap between the barrel and the pit and prime it with sand, clay or earth.

Make a cover with a protrusion 100 mm from the ground.

When installing such a septic tank, cut out the bottom of the barrel. The water will gradually be absorbed into the ground itself.

This method is only valid for small bathhouse where a bathroom will not be installed.

So, in this article we looked at options on how to make a septic tank for a bathhouse with your own hands. Some methods are very simple, so even without experience in this field big problems you won't have it. We will be interested to know about your experience in arranging a septic tank for a bathhouse. Leave feedback and comments at the end of this article.

This video shows how to design and install three-chamber septic tank with your own hands:

For the most part, owners suburban areas they set up a bathhouse on the territory, it doesn’t matter if the house is with permanent residence or dacha. Traditional construction requires wastewater disposal. Of course you can buy ready system, but the designs are expensive.

There is always a solution - to make a septic tank for a bathhouse with your own hands.

The first thing to decide is whether the building will be equipped with a toilet.

Drains from a bathhouse without a toilet contain epidermis, soapy water, a little grease and leaves from brooms. This allows the installation of any system without pumping. The presence of a latrine in a building changes the nature of the water; therefore, not every septic tank can cope with sewage waste.

Septic tanks for baths can be: single-chamber and two-section.

Kinds. Single chamber

Let's consider the options for single-chamber septic tanks and the type of their installation.

Pit for waste water under the bathhouse

The simplest and cheap option septic tank Organized at the time of laying the foundation. It is worth noting that a pit is relevant if there is no toilet in the bathhouse, the structure itself is not large and it is not used so often.

During the construction process, a pit is dug below the foundation, it is sealed, the bottom is filled with sand, crushed stone and gravel to a depth of 50-60 cm. The floor in the bathhouse is covered in such a way that water freely gets under it - into drain hole where it settles and filters natural filter and subsequent removal into the ground.

At this time, this type of septic tank is a thing of the past and is used extremely rarely.

Tire septic tank

A pit is dug next to the building, 2-3 meters deep. The diameter of the pit should be 15-20 cm larger than the diameter of the tires.

The bottom of the pit is covered with a natural filter. The tires themselves should be cut off on the sides for a tighter fit to each other. The products are connected to each other using any available means. The seams are sealed.

A hole is made in the top tire for the pipe, followed by connecting a pipe for drains.
The finished septic tank is covered with a sheet of iron or plastic. The remaining space in the pit is filled with soil along with the lid.
The septic tank is ready for use.

This design has such disadvantages as:

Pros:

Cheap
Easy and quick installation
Cannot be cleaned
When it has served its purpose, it is simply covered with soil and mounted in another place.

Septic tank made of concrete rings

Installation of such a septic tank is more complicated. For septic tanks they usually use standard rings and reinforced concrete 1 m high and outer diameter 1.16m

Rings are produced with special connecting elements, to facilitate installation. Installation takes place according to the scheme of a well made of tires. A pit is being organized.

The rings come down. They are connected and the seams are sealed. Bottom made of natural filter. A pipe is installed to drain wastewater. Cover with a tight lid (they are also commercially available). Covered with soil.

Reinforced concrete is very durable material. The reinforcement inside the rings stops the deformation of products during low temperatures and heavy loads.

Septic tank from a plastic barrel

Single-chamber drainage septic tank.

A barrel of the required size is purchased (usually 200 l). Holes are drilled across its entire surface at equal distances from each other. A hole is dug larger than the product in depth by 80 cm and diameter by 60 cm.

A pipe is installed in the bottom of the barrel. The main thing is to ensure that the connection between the pipe and the barrel is sealed. The bottom of the pit is covered with sand and compacted (spill it well with water), then filled with a mixture of sand, gravel, and crushed stone.

A barrel is installed on the finished bottom, with the bottom with the pipe facing up.

The product is wrapped in geofabric to avoid clogging of the holes. The remaining space, around the barrel, is filled with a natural filter up to the nozzle. The pipe is being connected. The top is filled with soil and covered with turf.

Single-chamber septic tank made of plastic rings

Installation of this septic tank is completely similar to the installation of a sump tank made of concrete rings.
The difference is that the products are easier to install.

Attention! All of the above septic tanks are designed for installation in a bathhouse without a toilet.

Septic tanks for baths with toilets

As already written above, a bathhouse with a toilet at the outlet produces wastewater containing human waste products, which implies additional water purification.
For buildings with a latrine, the majority install septic tanks with two chambers or two sections.
Two chambers are separate tanks.

Two-section - one drive divided by a partition into two sections.

Both septic tanks work on the same principle.

In the first chamber, liquid settles. Large particles settle to the bottom and form sludge, while those such as fat and insoluble particles rise to the surface and become a crust.

After settling, the purified liquid flows through a connecting pipe into a second tank, where additional sedimentation and filtration occurs using a natural filter.

Two-chamber septic tank made of concrete rings

Septic tank made of plastic barrels

This septic tank can be made in several versions.

First. Installation is carried out according to the type of concrete rings.
Second option. Sump from plastic barrel with a sealed lid, but the well can, for filtration, be made of a barrel with perforation and geofabric.
Third option. The barrel is divided into two sections by a partition. Here it is paramount to maintain the tightness of the compartments. The second compartment can be made drainage or an additional drainage well can be built.

This cleaning method is more productive.

Two-chamber septic tank made of plastic rings

The installation is the same as for a septic tank made of concrete rings.

Concrete septic tank

This type of treatment facility will require certain monetary and physical costs.

A septic tank diagram is being made.
A pit of regular geometric shape is dug out.
The formwork is constructed according to the diagram.
The concrete mixture is poured.
Important! When installing, leave holes for the pipes or insert them immediately.
The first section is made with a bottom. After the walls have dried, the screed is poured.
In the second section, the drainage filter takes the place of the bottom.

It is necessary to have a tight lid for the septic tank to stop bad smell and debris ingress.

Brick septic tank

Nowadays it is not installed very often.
Installation is carried out using the conventional bricklaying method.

Important! Half-brick masonry will not work, as when the soil freezes or the groundwater level rises, it may float or crack, which will break the seal and the structure will become unusable.

The rest of the installation is identical to the concrete septic tank.

Attention! All two-chamber septic tanks must be periodically cleaned of sediment.

Nuances of selection and installation

To correctly select and install a septic tank, you need to follow several rules.

Septic tank volume

It's worth making complex calculations by the amount of wastewater from the bathhouse.

Example. 6 people take a bath at a time. On average, everyone uses 50 liters of water

The septic tank must have a volume of at least 400 liters. Taking into account that no one will go to the bathhouse next. If it is designed for several visits in a row, then the volume triples.

If the bathhouse is equipped with a font

When choosing the volume of a septic tank, you should take into account the drainage of the container.

Results

Of course, baths are different. For baths with large area, a swimming pool, a toilet and a shower would be more practical to buy ready septic tank, septic tank or install an autonomous treatment facility.
