Sewerage is one of the most important elements of a private house, which will help ensure a comfortable life for residents. While apartment owners solve this problem by simply connecting to the central sewer network, summer residents or owners of a private house have to equip a sewer system from tires with their own hands. This is a simple and inexpensive option for arranging a private site.

The structure looks like a tank consisting of two or three chambers, the purpose of which is to collect, settle and filter waste, which is ensured by special bacteria.

As a rule, all liquid that has entered the septic tank from tires is cleaned by 97-98%, according to SanPin standards. Homeowners do not have to spend a lot of money to create such a structure, since worn tires are perfect as materials.

In this article, you can learn how to competently build a high-quality sewer from tires.

Rules for building a structure

Do-it-yourself sewerage from tires is an excellent solution for those who do not want to spend big money on building a septic tank, but want to get an effective design that will last a long time. In order for the system to work as it should, certain rules must be observed during construction.

This will serve as a guarantor not only of the successful functioning of the sewer system from tires, but also reduce the risk of environmental problems that may arise due to ignoring the basic requirements for arranging a septic tank.

It is important to follow the following basic rules:

It is possible to start building a septic tank from wheels, provided that the groundwater passes at a level below the 2-meter mark. This will ensure reliable fixation of the structure, which will exclude shifts, erosion or deformation due to heaving of the soil.
It is preferable to make a sewer on a site with sandy soil. As a result, optimal and fast drainage of purified water is achieved.
When building a sewer, it is necessary to take into account how deep the ground freezes. It is important to follow this rule even when building a small tank into which household waste will fall.
It should also be taken into account that the sewer from the wheels must be correctly positioned relative to other buildings and sources of drinking water located in a private area. So, the optimal distance between the house and the septic tank is 5 meters. Regarding water sources, it is necessary to locate the sewage system further from them by 20 meters or more. To minimize the risk of waste entering groundwater, it is recommended to place a septic tank from tires at the lowest point of the land.
The level of water intake is necessarily lower than the level of the treatment plant.
It is imperative to ensure unimpeded passage for the transport of the sewage treatment service.

Advantages:

lack of large cash costs;
short construction period of the sewerage;
you can build on your own without attracting a lot of people;
fit any tires, regardless of novelty and size;
uncomplicated construction.

Flaws:

poor performance;
serves an average of 10-15 years;
bad smell;
Incomplete sealing of tires increases the risk of soil contamination with sewage.

Also, such sewerage is not suitable for areas with high soil moisture. It should also be taken into account that if waste gets into surface or groundwater, the risk of developing dangerous infectious diseases in humans will increase.

What do you need to start building?

It is important to obtain permission to build a sewer network if the depth of the pit exceeds 5 meters. It is not difficult to get it, especially if you comply with all the conditions for surveying the site. These conditions are detailed in the Land Code of the Russian Federation. If there is a cadastral passport obtained before 2014, they should be redone. The cost of surveying itself varies within 6000 rubles.

Watch the video

If a communication cable passes through the site, special permission must be obtained from its owner. A specialist should arrive at the site and use a metal detector to establish a point where it is forbidden to dig.

The optimal location for the pit

After obtaining permission from all authorities, it is necessary to choose a place for the sewer system. There are certain norms established by Sanpin that you need to focus on. So, if the localization of the sump is close to the place where drinking water is extracted, the risk of sewage getting into groundwater increases.

Drinking water becomes unusable due to leakage. A sealed septic tank and a special filtration system will help to avoid contamination of the soil.

Also, you should not build a sewer in the vicinity of a house or a bathhouse, because otherwise the soil may settle during the construction of the pit, as a result of which the concrete base of the septic tank will be damaged. In addition, with blockages, it can get wet, which over time will lead to a decrease in its strength.

Too far the location of the tank from the house is also a bad option. This will significantly increase the cash costs for the construction of the structure.

As a rule, at least one manhole is required for the external part of the sewer. In the event that the pipeline is longer than 25 meters, additional wells will have to be added.

If the water supply is too long, it is likely that blockages will often form inside. This should be taken into account even though a special pump will be installed that will allow wastewater to be removed from the sewer.

Tire sump options

The choice of structure is carried out depending on how much wastewater will come out of the residential building. If few people live on the site, the simplest option will be enough for them.

Watch the video

For a family of more than four people, this option is not suitable, as it will quickly become unusable due to excessive workload. Therefore, experts recommend considering the option with two wells.

Sump with filter system

This is an inexpensive sewer option. To build it, you will need to dig a hole under the pit, equip the bottom and put the tires down. It should be borne in mind that such a septic tank is undesirable to build next to buildings or cellars.
It is better to give preference to wheels from large vehicles with a wide diameter, as they can accommodate more waste and increase the working capacity of the sewer.
The principle of operation of such a septic tank is simple:

waste flows through the sewer pipe into the well through the drain;
that part of the effluent that does not dissolve does not fall into the ground and remains on a layer of crushed stone;
the purified liquid is absorbed into the ground through the drain.

We also suggest that you familiarize yourself with the scheme of the device of a septic tank from tires. The main disadvantage of this design is that it is only suitable for domestic wastewater. It is not recommended to use it for the purpose of processing heavy insoluble waste, in which case it will quickly fail.

However, if the bottom is made airtight rather than draining, and the connection in the walls is impermeable, then this option will serve as a reservoir for all wastewater, which will often have to be pumped out in the future.

The main plus of sewage is that it is easy to build, and there will be no problems during operation. Expanded clay, sand and even idle earth are suitable as the top layer. Another disadvantage is that silt residue quickly appears at the bottom of the tank, as a result of which the pipe becomes clogged over time, complicating the outflow of water. In this case, the owners of the house or cottage will often have to resort to using a pump to pump out water and clean the bottom, and then replace the gravel.

Septic tank with two wells for settling and filtering water

This design is more complicated, but it will last a long time. The structure is represented by two reservoirs. One acts as a well in which the liquid settles, and the second filters it before it enters the ground.

Unlike the previous type of septic tank, this option has a sump with an impermeable bottom, in which the incoming sewage is settled. Insoluble waste remains at the bottom, and the remaining liquid passes into the absorption well, in order to subsequently undergo post-treatment by filtration.

The essence of the septic tank is as follows:

waste passes the first well;
the insoluble part remains at the bottom;
light liquid passes through the adjacent pipe into the cleaning chamber;
the liquid is filtered through a special system and then absorbed into the ground.

The advantage of this design is that it does not require large construction costs, and does not harm the environment, which makes it attractive in comparison with other options.

In addition, with the constant use of sewage, there is no need to create additional insulation.

Sump with drain pipe

Such a design is considered not the most suitable option for a private house. The drainage pipe does not perform special functions in the operation of the sewer.

The principle of operation of a septic tank is as follows:

waste flows into a special tank;
insoluble fractions settle to the bottom;
drain and crushed stone bring the filtered liquid into the ground.

The main essence of the design is that water passes through the pipeline, bypassing the bottom contaminated with silt. However, the pipe is quickly clogged with the same sludge and therefore it is short-lived.

Materials and tools necessary for the construction of sewerage from tires

In the event that the owner of a private plot cannot afford the installation of an expensive sewage system, he can perfectly cope with this task using the materials at hand, which, as a rule, are available from any home craftsman. For a septic tank, old car tires or tires are perfect.

This material is not so difficult to find, it is available at enterprises that write off tires and tires as unnecessary. In addition, you can find ads of individuals on the Internet. The best option is to go to a tire shop. There will be an abundance of old tires from various cars, and the owner of the service can give away badly worn tires for free, thereby saving on their disposal.

As noted earlier, any tires can be used. Of course, no one will purchase new material to build a sump, and rightly so. Worn products are just as suitable for a septic tank and do not deform in any way while in the ground. As you know, rubber does not rot and does not react to an aggressive environment.

To cut polypropylene pipes, you can take a regular, well-sharpened hunting knife. Liquid bitumen will be required to create impermeability of the areas where the elements are connected, and the pipe is also inserted. Of all the possible means, it is most suitable for the material of tires.

It is worth stocking up on sand, no matter what. It is perfect for digging a pit in which a septic tank and a trench with pipes will already be installed. Also, for such work, the “native” soil, which remained after digging the pit and trenches, is suitable. However, it is suitable only on the condition that it does not contain layers of loose soil with a high concentration of sand and clay.

The drainage layer also needs to be backfilled. For this purpose, crushed stone "caliber" from 5 to 20 mm is suitable. You need to fall asleep about 1 meter. It is not necessary to use expensive gravel for backfilling, any budget option will do. Plastic clamps are used to fasten tires, but you can use ordinary wire instead.

How many materials will be needed

The number of pipes is determined by the distance between the tire septic tank and the house. It is advisable to take products with a margin, since during construction they can be deformed. You will also need another pipe to connect both septic tanks.

Five clamps are required for two wheels, so you should be guided by this data when buying materials. If you take a knitting wire instead, 1-2 meters will be enough. To protect against moisture, you need a piece of rubber and one roll of roofing material.

To equip a filter pad, you need to take 2 tons of gravel and sand. PGS is also suitable, but then the quality of wastewater treatment will decrease, since the sand will quickly become contaminated with silt.

Construction of a septic tank from tires

It is worth starting the construction of a sewerage system from tires when all the materials have been purchased and a drainage system from a country house has been installed.

It is best to sketch out a sketch of the septic tank in order to accurately calculate how much material is needed, how deep the bottom of the structure needs to be laid, and where and at what depth the pipes will run.

Watch the video

Installation of tires will not cause difficulties to the owner of the site. But the preparation of the pit will be a rather laborious process. This work is difficult to do on your own, you can spend at least a week on it. With the manual development of the pit, the most difficult process is the extraction of soil, especially if the depth exceeds 1.5 meters.

For this purpose, something like a bucket, fixed with a rope, with which the blade will be lifted, as well as a cart to remove excess soil, is ideal. For example, you can use the services of special equipment - an excavator, thereby facilitating and speeding up the process.

Pit preparation

With the help of an ax, it is necessary to get rid of the roots of plants growing in the pit, since many of them can germinate in the future and deform the integrity of the septic tank. Then you should level the place for the construction of the bottom. This will ensure that the rubber is securely fixed and sealed to the bottom surface of the tire, so you should try to make the bottom as flat as possible.

Watch the video

The place where the bottom of the cleaning chamber will be located must be additionally increased downward by 30 - 60 cm. It is not necessary to level the layer, since gravel will lie on top.

Laying tires for a septic tank

Construction of a structure for a cleaning system

Basically, the instruction is similar to the one described above, except for a few points. Firstly, the bottom should be sandy, the first tire is placed on it, which is covered with rubble or gravel. Then the next wheel is placed. Secondly, four tires are useful, in the last of which holes are made for the drain pipe. The last two steps are similar to the previous instructions.

Having finished with the installation of tanks for sedimentation and filtration, you should begin to lay pipes between the wells. The pipe diameter is 110 mm, since during operation a greasy coating forms on its walls. Over time, the lumen of the pipe will decrease.

Connection of a septic tank from tires and a wastewater treatment tank

This will require a grinder, with which two holes are cut either at the bottom of the third tire or at the top of the second. It should be borne in mind that the exit from the septic tank to the tank is one level lower than the drain pipe from the living quarters is located. The pipe must be installed horizontally and tilted by 15-20 degrees.

Additional sealing is required at the points of contact between the pipe and tires. This is done using small patches cut from roofing felt, and liquid bitumen is used as glue. This eliminates the risk of pipe contamination. Only after that should proceed to the final stage.

We install ventilation

Be sure to equip the external branch of the sewer with a ventilation pipe. It is advisable to make it in the lid of the cleaning tank. The most preferred option is to install ventilation in two places: at the exit from the house and above the cleaning well.

An opening may form between the walls of the wells and the pit, it should be covered with sand. From time to time it will be necessary to tamp the earth.

Watch the video

As soon as the first rain passes, the soil in the pit will settle, so you will need to fill it with earth again. The septic tank itself can be covered with simple iron covers.

A septic tank made of tires in a private house will last about 15 years. Pumping out will be required only for the sump when it is filled to the brim with heavy sewage components.

Conclusion

In this article, it was described in detail how to make a sewer from tires with your own hands. Not only does this not require large financial outlays, but it is also quite simple: you do not need to be a builder to build a structure from rubber tires.

At the same time, it is still important to take into account a few basic rules that will help you properly build a cesspool or septic tank in a private house. Care must be taken to seal all joints and seams between the wheels to prevent sewage from entering the ground.
It is worth deciding in advance on the type of structure and the place of its localization.

The location of the sewer must meet all the standards previously indicated in the article. Also, the structure itself must be installed below the freezing level of the soil.

Entries

Given the rare seasonal attendance of the cottage (for example, only for beds or harvesting), there is no need to install expensive cleaning stations or. A sewer system operating without a maximum load will completely manage with a simple pit, the walls of which are assembled from old car tires.

In such a pit, you can dump both water from the shower and sinks, and the contents of home toilets. And construction work does not require any special skills from the owners. The cost of sewerage will be extremely low. After all, the main building material often comes free of charge from friends or neighbors who have replaced the old tires of their car with new ones.

At first glance, such a sewer pit has many advantages:

she can get by the owners for free;
the construction takes a maximum of one day;
tires of any size can be used;
you can build alone.

However, such a structure also has serious shortcomings, such as:

short service life (on average up to 10 years);
poor tightness of sections (in fact, its absence);
the presence of an unpleasant odor;
poor performance;
inexpediency of repair or dismantling.

In addition, a structure of this type is absolutely not suitable for sites with.

The ingress of sewage waste into surface and ground waters is fraught with the spread of infections dangerous to human health.

Principle of operation

The pit is actually a sump with the ability to filter the contents into the surrounding soil. Through the gaps in the walls, the liquid gradually goes into the soil, and large organic matter settles to the bottom. Rotting is a mandatory attribute of the pit.

At the same time, you can not put an equal sign between a classic and a septic tank built from tires! The latter has a much rarer pumping with the involvement of sewage equipment.

If desired, a simple cleaning system can be built from tires. To do this, two pits (wells) are interconnected by overflow pipes. The primary sedimentation tank takes on most of the large organic impurities. In the second chamber there is only partially clarified water, which is quickly absorbed into the soil.

In this case, the decomposition processes will be accelerated and the presence of a sewer odor will partially decrease.

How does it work?

A hole for tires is dug only in areas with deep groundwater! The minimum distance from the bottom of the structure to the upper water layer is 100 centimeters.

The possible risk of contamination of drinking water should also be taken into account. Therefore, the pit is placed taking into account the characteristics of the soil and the distance to or. For sandstones, this is 30 meters, and for clay soils - 20 meters. The construction is separated from residential buildings by at least 5-6 meters.

It is desirable to place the structure on the natural slope of the site, that is, below the level of the water intake. Pipes and the sewer tank itself must be placed below the freezing point of the soil in a particular region! Some resourceful owners enclose both the pipes and the septic tank in a special wood box. This engineering feature prevents deformation in case of possible freezing of the soil.

What materials are suitable?

As mentioned above, any tires can be used. Naturally, these will be already used, rather worn-out products. But wear will not affect the safety of tires in the ground- rubber does not rot and does not react with aggressive environments.

To increase the volume of the structure, it is advisable to choose tires from large vehicles (if possible) - trucks, tractors, buses. Tires for domestic passenger cars have a metal frame that provides additional rigidity.

How to build?

For work, you will need the following tools and materials:

shovel and bayonet shovel;

knife for cutting rubber;
electric jigsaw;
sewer;
wire for fastening structural parts;
cover (hatch) of suitable diameter;
sand for sprinkling, but you can use ordinary soil;
tires in the amount of 5-7 pieces (so much will be needed to serve two or three people).

The step by step installation looks like this:

Marking is made for both sections of the septic system. To do this, the tire is placed on the ground and the perimeter is marked.
A common hole is dug with a small margin to ensure free play when the tires are lowered. The bottom of the pit can be covered with sand, clay (additional tightness is provided) or poured with concrete (such a base prevents deformation during soil heaving).
The details of the structure are being prepared - the upper part of each tire is removed with a jigsaw, which ensures the most even surface of the walls (there will be nothing for sewage to linger on).
Tires alternately lowered into the pit and tied with wire. Additional tightness can be achieved by lubricating the joints with rubber glue.
An overflow pipe is installed between the wells (about two-thirds from the bottom of the structure).
Sewerage is connected to the first well. To do this, a hole is cut in the tire. For connection, a rubber coupling and sealant are used.
The pit is filled with soil or sand. The backfill is carefully compacted around the perimeter of the structure.
A cover is installed on top. It can be a polymer hatch, an iron or wooden cover.
An access platform is being built around in case of a call for vacuum trucks. On this construction work is considered completed.

And to get rid of the unpleasant smell, you need to install a pipe. The closer the sewer drain is to residential buildings, the higher the pipe should be. Much also depends on the prevailing winds in a particular area. It is better to position the structure so that the wind blows the smell away from the house.

Errors made during installation are as follows:

the slope of the main pipeline is not respected - the waste slowly drains, the pipe becomes clogged;
the level between the inlet and outlet pipe is not observed - the overflow pipe must be
below the incoming sewer, between the wells, it is also located at a slope of 20 centimeters;
the structure is located above the freezing point of the soil - pipes suffer in winter;
the structure is immersed in groundwater - working containers silt up, often float up, the infection enters the soil.

Construction cost

If the owners did not manage to get tires for free, you can purchase a used set of two pieces of these products at a price of 1,200 rubles. There are also cheaper options.

Construction work is carried out independently or with the involvement of a digger and plumber. The range of prices for earthworks ranges from 240-600 rubles per cubic meter of volume. Plumbing services will cost from 500 rubles (relevant for the Moscow region).

How to operate?

The use of such sewerage is subject to all the basic rules that apply to any sewer systems.

Properly installed sewerage means:

A do-it-yourself septic tank made of tires is an excellent replacement for a standard sewerage system in the absence of conditions for arranging communications. This is a simple and practical option that is easy to build without serious cost and effort. Next, we will consider in detail the entire process of arrangement and give valuable advice.

Many mistakenly believe that a septic tank and a cesspool are one and the same, since all the contents have to be pumped out. However, this is not the case - the differences are significant. It is a reservoir that needs to be emptied as it fills up. A septic tank is a system in which biological wastewater treatment takes place. Yes, it also needs to be cleaned from time to time, but much less often than a cesspool.

Septic tank at the dacha

The septic system consists of two sealed tanks that are interconnected. Wastewater from the sewer enters the first tank - this is the primary treatment zone, in which large particles of pollution settle. Bacteria that clean drains also “work” here. All sewage remains at the bottom, while the purified water reaches the overflow located in the upper part, and enters the second tank, which has a larger volume than the first chamber. True, you still have to pump out part of the content.

If you decide to make a septic tank, but do not have free funds, you can make a structure from car tires. Consider the advantages and disadvantages of such a sewer system. The advantages of a septic tank from tires are as follows.

Almost zero cost. You can keep old tires, or you can buy them for almost nothing at any service station.
Ease of installation. If the installation of some types of septic tanks is impossible without the involvement of special equipment and builders, then in this case the installation can be easily carried out by one person.
Excellent performance for a DIY design.

Tire septic tank

But, unfortunately, there are also disadvantages. The main ones include the fact that septic tanks made of this material are designed to serve a small family of up to three people. If your house has more residents, it is better to choose a different sewer option. Also, tires are not the best material for operation in the winter. No matter how you insulate them, they will still freeze, which can cause the entire sewer system to freeze.

Another disadvantage is the frequent pumping (at least once a quarter) of the content. It is worth mentioning the not too good tightness of such a design. Therefore, once every six months, it is imperative to check the joints for gaps and leaks, and, if necessary, carry out additional sealing. The fragility of the design is also attributed to its shortcomings. I must say that there is simply no point in repairing such a septic tank in the event of serious damage - it is better to find new tires and equip everything anew, or from other materials (barrels, European cups, bricks).

There are more negative sides to a septic tank from tires than positive ones, but in some cases, when there is no other option, and an autonomous sewage system is urgently needed, this type of septic tank can save the situation. Therefore, information on how to make a sewer in a private house from tires will be of interest even to those who are not going to build it - you never know, one day it will come in handy.

Before starting construction, you need to decide on the size and number of tires that we need. To do this, you need to calculate the approximate volume of the primary chamber of the structure, which directly depends on the number of people living in the house. According to experts, one person spends about 200 liters of water per day (for washing, cooking, washing).

Multiply this figure by the number of people living in the house, and you get the desired volume, which, if necessary, can be slightly adjusted upwards, taking into account the use of various household appliances, the arrival of guests. Using the mathematical formula for calculating the volume of a cylinder, it is easy to calculate the height of the septic tank, and only then the required number of tires, depending on their size and height.

Here is the formula: V = π r2h, where:

V is the volume of the septic tank;
r2 – tire radius;
π is a constant value equal to 3.14;
h is the height of the tire.

The formula for calculating the volume of a cylinder

The next step is the placement of the septic tank. Here you can not do without the advice of experts:

The structure must be placed at a sufficient distance from drinking water sources (at least 20 m in the presence of clay soil on the site, and about 50 m in sandy soil).
From the sewer to the residential building must be at least 10 m.
It is necessary to provide for the possibility of pumping out the contents from the septic tank, for which it is necessary to provide the possibility of the access of a sewage truck.
We should not forget about the comfort of the neighbors - you should not place the septic tank too close to their site.

A simple instruction for beginners - we will make a septic tank in one day

Let's look at a simple instruction for arranging a septic tank from tires on your site:

Instruction

Step 1: Support Profile

So, first of all, we carry out marking around the perimeter of the bathroom for mounting the wall profile, which will be installed before other complete fasteners. We make marks on each wall with equal indentation from the floor. Attention! It is necessary to measure from the floor, since the ceiling can be laid crookedly, and this is what should be hidden with the help of a suspended structure. Therefore, it is important that all sections of the coating be at the same height from below. Next, we beat off the line on each wall with a coated thread and fasten the profiles with the help of screws.

Step 2: Attach the hangers

The next step will require you to accurately calculate. For each stringer, the length of which can vary from 3 to 4 meters (if necessary, you can saw off the excess), the suspensions must be placed on the same line. At the same time, the distance between them can be about 120 centimeters, as well as between rows. Based on this, we make markings, drill holes in the ceiling, insert plastic dowels into them and fasten the suspensions with screws through special loops. With the help of adjusting springs, we set all the knitting needles so that their hooks, on which the stringers are suspended, are at the same level and always above the wall profile.

Step 3: Hanging Structure Installation

Now it remains only to pass the suspension hooks through the special grooves in the stringers, after which we carefully adjust the entire system again using the level. Be sure to cut the traverses so that there is a distance of about 5 millimeters from their ends to the walls. Next, we begin to snap the rails, but before that you need to make sure that the panels will lie almost without gaps on the shelves of the wall profiles. You need to start assembling the skin from the edge. At the same stage, we lay the wires behind the structure and mount the fixtures.

Now you know how to equip a septic tank on your territory. We will give some more useful recommendations.

To protect yourself from the penetration of an unpleasant smell from the sewer, equip the septic tank on the leeward side of the house.

When digging a hole, it is best to use two shovels with different handles: a bayonet for loosening the soil and a shovel for picking the earth out of the hole. Also arm yourself with a crowbar that will help you if the ground on the site turns out to be rocky.

For convenience, make a small viewing window in the septic tank hatch, which can be covered with a piece of rubber. So it is much more convenient to control the level of fullness of the septic tank. We also advise you to wrap the tires in several layers of roofing material before pouring rubble. This will insulate the septic tank (for use in winter), as well as save the environment from untreated drains.

A well-maintained house is, first of all, housing where sewerage is carried out. Unfortunately, not everywhere there are conditions for arranging communications. Often you have to resort to unusual ways to create it, for example, to arrange a septic tank from tires, a simple and practical option that allows you to provide your home with a sewer system at no extra cost. However, you need to understand that such a structure is not intended for large volumes of wastewater, so it is chosen if a small number of people use the sewer.

Septic tank: difference from a cesspool and the principle of operation

Many mentally put an equal sign between a cesspool and a septic tank, confident that since they have to be pumped out, then there is no difference. However, it is not. The difference is colossal. A cesspool is an ordinary tank that is emptied as it fills up. Whereas a septic tank, equipped with tires, is a system that performs biological wastewater treatment. He also needs pumping out at times, but much less often than a cesspool.

The system consists of two sealed tanks connected to each other. Wastewater enters the first tank directly from the sewer pipe. This area can be considered a zone of primary treatment, in which large particles of contaminants are deposited. This is where the work of bacteria that cleans the drains begins.

The sewage settles to the bottom, only the initially purified water reaches the overflow zone, which is located in the upper part, and enters the second chamber. It is slightly larger than the first one. Here, the active work of bacteria continues, only it happens much more intensively.

Basic rules for arranging a structure

When choosing a place for a septic tank, you need to consider the following:

Between the upper level of groundwater and the bottom of the structure there must be at least a meter of soil.
The distance from the drinking water intake to the septic tank is at least 50 m for sandy soils and 20 meters for clay soils.
There should be a free access for a sewage truck.
The distance from the house to the septic tank is at least 5 m.
If possible, the structure is arranged so that its level is below the water intake, that is, towards the natural slope of the landscape.

A sewer pipe must be connected to the septic tank. So that it does not suffer in the cold, it is best to lay it below the freezing level of the soil. You can equip a special protective box in which it will be reliably protected from mechanical damage and will be able to “play” from temperature differences without consequences.

System installation features

Having chosen a place for the structure, you need to decide on its volume. It is generally considered that it should be equal to at least three times the daily flow rate. Based on this, the approximate depth of the structure is calculated. Most often, it is equal to the height of 5-7 tires.

Considering that tires can be very different, both from passenger cars and from powerful agricultural machinery, the volume of the structure also varies.

When laying tires in a pit, they can be fastened to each other, then the structure will be stronger

Work is being carried out in stages:

Markup. The tire intended for the first well is taken and laid on the ground. It marks the dimensions of the future well. At some distance, a tire is laid, intended for the second container. It may be of a larger diameter, since the volume of the second well must be larger. It is also labeled. Then a hole of the required size is dug for both containers.
Arrangement of the bottom of wells. It should not let impurities into the ground. The surface can be concreted or equipped with a so-called "clay plug", 20-25 cm wide.
Tire preparation. In each of the tires, using an electric jigsaw, the upper part is carefully removed. After installation, such parts form a well with more even walls, which will prevent sewage from lingering on them.
Tire installation. Tires are stacked one on top of the other. At the same time, for the strength of the connection, they can be pierced in pairs and tied with wire. Each joint and seam is carefully coated with sealant. Between the wells at a height of approximately 2/3 from the bottom, a transition pipe should be inserted, under which a hole is cut. In the upper part of the first well, a hole is also cut out for a sewer pipe stretched from the house.
Laying pipes between wells. For these purposes, an ordinary plastic sewer pipe is suitable. A structure is also inserted and fixed inside the hole, supplying drains from the house.
Filling the pit. For these purposes, you can use sand or soil that was taken out when digging a hole. The operation is carried out carefully so as not to damage the integrity of the structure.
Cover arrangement. Wells must be closed with lids, it is desirable that the material from which they are made does not rot.

The structure is ready for operation.

The overflow pipe between the tanks is mounted in a hole cut in the tires

The main advantage of this option is low cost and ease of installation. There are, however, also disadvantages:

A small amount of wastewater that she can recycle.
A rather high risk of contamination of the soil with sewage, since it is difficult to achieve complete tightness from tires.

Also, if you are going to equip such a septic tank from tires with your own hands, you need to understand that the structure belongs to the class of storage septic tanks, therefore, it requires pumping out the accumulated liquid.

Some owners of suburban buildings are attempting to equip a full-fledged three-chamber septic tank from tires. However, it is worth noting that although technically it is quite possible, tires are not the best material for such structures. It is unlikely that it will be possible to provide the tightness necessary for the effective operation of the septic tank. In addition, interconnected tires can gradually move as a result of seasonal temperature fluctuations in the soil, which further violates the tightness of each chamber. As a septic tank, the tire construction serves very well, allowing you to enjoy the benefits of civilization even far from the city.

Well-maintained housing assumes the presence of sewage, which removes wastewater from the house. A tire septic tank is a simple and inexpensive option for arranging such a system. It can be easily made with your own hands, using household tools and improvised materials. But, when making such a decision, it is necessary to take into account a number of nuances related to the features of the construction and operation of such a structure. Consider all the pros and cons, possible problems and ways to solve them.

First of all, let's focus on the advantages:

Availability of raw materials. You can find worn tires along the road, in wastelands and landfills. It remains only to deliver them to the site.
Easy assembly. Fragments for the well are lightweight, they can be moved and lowered into the pit alone, without the involvement of mechanization.
Ease of processing. Reinforced rubber is cut and drilled with household tools. Fragments are fastened with inexpensive hardware.
Durability. The wheels are resistant to chemically active liquids, do not decompose under the influence of high and low temperatures.

Disadvantages of a septic tank from tires in a private house:

the difficulty to achieve stable tightness;
low throughput;
insufficient resistance to soil pressure during soil heaving.

Principles of a septic tank from tires

Wastewater treatment technology consists in the decomposition of organic compounds into environmentally friendly elements with the help of anaerobic bacteria.

The cleaning system consists of two or three interconnected tanks. In the first, primary purification is performed: heavy fractions settle to the bottom, light fractions linger on the grid, and the settled liquid is exposed to microorganisms. There are more bacteria in the second container; they process organic compounds into neutral substances, releasing solid sediment and nitrogen. Almost pure water enters the third chamber. It is absorbed into the ground or taken for economic purposes.

A septic tank made of tires in a private house, like a cesspool, must be periodically cleaned. This is done by hand, the waste is used as fertilizer.

Construction cost

The price of factory autonomous devices of a closed type is 15,000-30,000 rubles.

The cost items for building a septic tank with your own hands from tires are as follows:

Tires. You will have to spend money on gasoline for their delivery.
Pit and trenches. Renting an excavator costs an average of 1000 rubles. per hour plus round trip.
Connecting pipes and fittings. A complete set costs 800-1200 rubles.
Waterproofing of tire joints. Sealant will cost 1000-1200 rubles.
Fasteners. It will take 20-25 bolts with nuts to connect one joint (up to 800 rubles).
200-400 kg of sand and gravel for filtering wastewater (400-600 rubles).

Thus, the cost of arranging a septic tank from tires with your own hands will amount to 5000-6000 rubles.

The main options for a septic tank from tires

Wastewater treatment facilities are manufactured to perform tasks of various sizes. The most common option is the arrangement of general purpose facilities that collect polluted water from all consumers in the house. Such structures are large in size and complex in structure.

Some property owners take a different approach, making several local septic tanks from tires with their own hands. Some are designed for residential sewerage, others clean drains from a summer shower, kitchen and bath. The composition and internal structure of structures differ. The latter depends on factors such as throughput and required degree of purification.

Sewer structure with filter system

Such structures consist of one large reservoir. Its bottom is lined with a thick cushion of sand, fine and coarse gravel, stone chips and sorbents. Water seeps through the filter, which is purified by anaerobic bacteria. The sediment that has fallen to the bottom is removed as needed. The advantages of this design are its simplicity and low construction costs. Minus - filtered water goes into the ground, it can not be used on the farm. The second drawback is the limited possibilities of the structure.

Construction with a sump and filter system

This is a more complex system consisting of two tanks. In the first, a preliminary treatment of wastewater takes place. They are separated into solid fractions that precipitate and light fractions that are processed by microorganisms. Partially purified water enters the second tank, where the final purification takes place. Solid fragments settle on the filter, through which water is absorbed into the soil. This design is able to process more liquid. At the same time, the quality of the final product reaches 95-97% of the sanitary standards.

Tire septic tank with drain pipe

A system with this design is installed in areas with a high level of groundwater or dense clay soil. In such cases, the treated effluents are not absorbed, they have to be scooped out manually. Another factor of choice is fluid deficiency and the need to conserve every liter.

The discharge of purified water is carried out in a special storage tank. The liquid flows down under the influence of gravity during a height difference or is pumped out by a pump as the container is filled.

Rules for arranging a septic tank

A septic tank for a summer residence is a complex engineering structure, which should be done in such a way as to prevent it from flooding, depressurization and extrusion during heaving of the soil.

When designing and building, you must adhere to the following rules:

The bottom of the well is fixed in the ground with a heavy and durable anchor. For this, a concrete slab is used.
The joints are sealed with a substance that retains elasticity at low temperatures and prolonged contact with an alkaline environment.
The tires are rigidly connected to each other to avoid horizontal displacement due to ground pressure.
The bottom of the sump should be well insulated from the ground.
Tanks are equipped with exhaust pipes to remove nitrogen released by bacteria.

Containers are closed with strong lids. It is better to fasten them on hinges to prevent accidental shifting.

How to properly position a septic tank on the site (requirements)

According to the requirements of SNiP and SanPiN, the following rules apply to the location of the septic tank:

the height of the bottom of the well above the upper level of groundwater is 50 cm;
distance to drinking water intake - 20 m for clay soil and 50 m for sandy;
distance from residential buildings - 5 m;
the distance to the fence is at least 1 m.

Do not equip the structure next to shrubs and trees. Plants constantly grow roots that can damage the well.

Where and how to remove the sewer pipe

Supply, connecting and discharge pipes are laid to the tanks. Depending on the design of buildings, communications are laid under their foundations or through pre-made holes.

A number of nuances should be taken into account:

slope sufficient for gravity;
arrangement of a pillow of sand to compensate for seasonal ground movements;
pipe insulation above the freezing point;
sealing with cuffs of places where pipes are inserted into tanks.

In moving soils, communications are laid in protective boxes.

Stages of work on the arrangement of a septic tank

The construction of the treatment system is carried out in the following sequence:

Carrying out markup.
Excerpt of pits and trenches.
Cutting off the inner protrusions of the tires.
Bottom sealing, anchor making.
Laying tires, applying sealant and tightening fragments with hardware.
Pipeline laying, connection of system elements.
Cover fabrication and installation.
Filling openings with sand and gravel.

In conclusion, a decorative design of the septic tank is carried out.

When planning, you need to accurately calculate the volume of the tanks. It should be at least 3 times the volume of daily effluents. It is better to choose wide tires from tractors and heavy trucks. Such raw materials are characterized by high strength and large size. With a slight recess in the ground, they create a useful volume that meets the calculated needs.
