Owners of private houses often face the problem of wastewater disposal due to the lack of a centralized sewage system outside the city. For a long time, the only solution was to dig a cesspool, but using it is quite inconvenient and costly. Nowadays, they are mainly trying to install an autonomous wastewater treatment unit - a septic tank for a dacha, but which septic tank is better to choose for specific conditions often remains a difficult question.
Together with the technical specialists of the EcoDom company, in this article we will examine in detail the question of which septic tank is right for you and discuss the best options based on the problems that it should solve.
The cesspool or storage septic tank will have to be cleaned regularly
Some people mistakenly call a septic tank a complete set of treatment equipment. In fact, this is only part of the treatment facility, which acts as a storage tank and primary filter for wastewater containing a large amount of biomaterials that require disposal.
There are quite a lot of types of septic tanks created and each of them has its own pros and cons. Therefore, before purchasing, you need to consider on what basis it is worth Vacation home, the amount of water consumed and of course the budget that can be allocated for purchase and installation.
Briefly about septic tanks in the video:
Also on initial stage you need to decide on the type of device - purchase a non-volatile septic tank or one that has a forced supply of wastewater (volatile). The first, by and large, are ordinary tanks for surface (within 60%) mechanical treatment of wastewater, and the second are equipped with a pump and a set of additional filters, after which the output is process water that is 95-98% purified.
Septic tanks with a full cleaning cycle and a storage well for process water
You can correctly decide which septic tank to choose - for year-round use or one that can work effectively even with periodic supply of wastewater on your own, since there is enough information. Many turn to the help of the Internet for such requests as rating of septic tanks for a country house 2017, to get acquainted with various ratings of septic tanks. But if you have doubts about the correct choice, then the best option would be to turn to professionals. They will take into account all the nuances and select the appropriate option, tailored to solve specific problems.
Wastewater goes through several stages of purification in a septic tank:
Stage of accumulation and settling. This stage consists of collecting waste in a special container, where it is separated into fractions by settling at a temperature of about 20 degrees. Solid particles in the form of sediment fall to the bottom, fatty deposits float to the surface, and evaporation ( carbon dioxide and methane) are removed through ventilation to the outside. At this stage, partial stratification of wastewater occurs, which is then sent to the next container;
Secondary filtration stage. Its goal is to purify the mixture to approximately 75%. At this stage, the solution is purified using a separate filter consisting of a sorbent layer of about 20 centimeters. In some septic tanks, for proper operation, the sorbent must be washed and reactivated annually;
Stages of wastewater treatment in septic tanks
Solid deposits settled in containers are pumped out with a pump or removed mechanically.
Technically, two types of waste disposal are used: anaerobic (without access of air) and aerobic (decomposition with the participation of bacteria that require oxygen for life).
Septic tanks have an anaerobic mechanism of action, which perform the functions of a storage tank or settling tank. Such cleaning systems without installation additional equipment They carry out only primary clarification of wastewater and require frequent pumping with a sewer machine.
Important! According to sanitary standards Discharge of liquid from anaerobic septic tanks into the soil is prohibited.
This option is suitable for rarely visited summer cottages or private houses with a small number of inhabitants. The cost of such a structure is low, installation does not require much effort, and operation does not require constant flow of wastewater into the chambers
The principle of operation of an anaerobic septic tank
Colonies of active bacteria are often added to such septic tanks, which help filter wastewater better than with conventional anaerobic purification.
The aerobic mechanism of action is carried out by local purification stations of biological action. Colonies of aerobic bacteria are added to such septic tanks, which effectively purify wastewater.
Unlike anaerobic crops, they multiply quickly, have a wide variety of species, and are also more tenacious and active. Recycling is much faster, and the output water is practically non-toxic.
For the normal functioning of these septic tanks, the installation of aerators is required, which will supply the oxygen necessary for the life of bacteria. Also, aerobic systems must constantly work - if within 2-3 weeks there is no new effluent entering the chamber, the bacteria will die and their cultures will have to be replanted.
Obviously, the best septic tank for a country house is aerobic. But it all depends on the budget, since cleaning stations of this type are more expensive.
Scheme of operation of a septic tank for aerobic treatment
An important aspect when buying a septic tank is the choice of material from which it is made. Most often, when ordering a ready-made septic tank, it is made from polymer materials.
In addition, the following materials are used for the manufacture of a local cleaning system:
Metal constructions. Rarely used due to susceptibility to corrosion, general impracticality and inconvenience of use;
Concrete. Monolithic structures are used as reservoirs. This option requires considerable investment of money and time; Mainly used when constructing septic tanks with your own hands;
Fiberglass structures– the most suitable and frequently used material.
Also, septic tanks can be made from scrap materials (barrels, tires) yourself, but this option is only suitable for small country houses.
Homemade small septic tanks for the dacha - from tires and concrete rings
You can save on purchasing a cleaning unit by ordering from the manufacturer. The most expensive on the market are septic tanks with additional equipment for complete biological wastewater treatment.
According to the degree of their autonomy, cleaning systems are divided into:
Non-volatile (autonomous) septic tanks are settling tanks for the accumulation and clarification of wastewater. Such installations require periodic pumping of waste using a sewer truck. They have a low degree of purification and require additional ground filtration, for which it is necessary to allocate a plot of land. TO positive aspects low cost and independence from electricity;
Volatile septic tanks are the complete opposite of non-volatile structures. Thanks to the design and additional equipment, wastewater in such systems undergoes a full cycle of processing and purification, which eliminates the need for maintenance. Disadvantages include the cost of installation, as well as dependence on electricity. During a lack of power supply, the degree of purification of sewage water decreases, and the septic tank acts as a septic tank.
A pump and an aerator are essential components of a volatile septic tank.
Before choosing a suitable septic tank, you need to consider the following aspects:
The number of people living in the house - the power of the entire device depends on this;
The material from which the septic tank is made determines its wear resistance and resistance to aggressive influences;
The terrain where the structure will be installed and the height of groundwater;
The complexity of installing a sewage treatment system - in terms of installation cost, septic tanks with a filtration field are in the lead, and the most profitable in this regard are biological treatment stations - their container simply needs to be buried in the ground;
Own budget.
On our website you can find contacts of companies specializing in septic tanks and autonomous sewers For country houses. You can communicate directly with representatives by visiting the “Low-Rise Country” exhibition of houses.

This is not a complete rating of septic tanks for the home - there are still quite a lot of models of such devices, both domestic and foreign, but in general their design, principle of operation and price do not differ from those listed.
A few more words about choosing a septic tank in the video:
Depending on your budget, you can make a cleaning system yourself from available materials, or order a ready-made version from sales representatives or the manufacturer. The option of studying the ratings of the best septic tanks for a country house is not always the right choice, since you need to take into account all the features of your particular site and the requirements for it.
A correctly selected and correctly installed septic tank will create the conditions necessary for comfortable living in a country house.
When a residential building is built, a sewer system is planned, as a rule, an independent one. Previously, a cesspool was used for all sewage; today, an autonomous septic tank for a private home has become popular. These are innovative designs for wastewater treatment, which are an air- and water-tight vessel, usually divided into several chambers.
In this device, household wastewater is first settled, then special microorganisms process it, and then the wastewater is filtered. A huge selection of bio purifiers confronts consumers with current issues, which is the best septic tank for a summer cottage with periodic rest, and which disposal is more suitable for a permanent home? Should I buy a ready-made unit or make the purifier myself? We will try to answer these questions in this article.
Bioseptic tanks are a local installation, which is a system of an autonomous sewer system for a private house. This treatment plant is installed in those areas where it is impossible to connect to the central sewer system, that is, near country houses of non-permanent residence and country houses.
It is advisable to install a deep cleaning station next to a river or pond.
To choose the best bio septic tank, you need to understand the operating principle of this design, which will help you pay attention to the appropriate parameters when choosing a tank. Therefore, let's look at how this design works:
When answering the question of which septic tank to choose for a permanent or temporary home, experts advise paying attention to waste disposal units that are equipped with a deep-cleaning biological filter. Autonomous treatment stations of this type provide complete water purification, eliminating the need to construct filtration fields.
There are many types of local septic tanks that can be used to clean wastewater from a private home: from the simplest do-it-yourself structures to autonomous installations that allow you to purify wastewater to almost 100%.
Treatment stations are systematized according to various criteria:
Bio purifiers are also classified into three types, depending on the set of functions they implement:
In order for a closed sewer system to work more actively, it is recommended to equip an anaerobic septic tank, which involves the colonization of special bacteria in the primary treatment chamber. These microorganisms feed on organic matter and do not require oxygen. This measure will speed up the disinfection and dissolution of waste.
If you remove the ventilation pipe from the post-treatment chamber or connect an air compressor, you will have another aerobic septic tank. To do this, you need to add special microorganisms to it that process organic substances when oxygen is available.
Biological decomposition of sewage by one or another type of microorganisms allows waste to be purified to the state of industrial water.
To solve the problem of which bio septic tanks are best to choose for a private home, you need to consider the problem from several perspectives:
First, you need to decide whether to make a sump yourself or purchase a ready-made tank. In the first case, the structure is made of brick, concrete rings or tires. However, such a cleaner is only suitable for homes with seasonal or periodic occupancy. For a long time and safe use It’s better to choose a factory model, even the cheapest one, since the purchased version meets all environmental and sanitary standards.
At the same time, it is not advisable to purchase the most expensive treatment plants, which allow purified water to be discharged directly into a reservoir, for private use, but it is not so expensive for several farms. For individual use, it is better to choose a two-capacity disposal unit. The first compartment collects sewage and performs its primary purification, and the second compartment filters the liquid and releases it into the ground, and not into water bodies.
Secondly, you need to choose the material for making the tank. This criterion affects the service life of the vessel. So, for the manufacture of cleaning stations they use:
Thirdly, you need to consider the type of soil on the site. Recommendations for specific conditions:
The capacity of the waste disposal facility is calculated based on the average daily rate of sewage per person (bath or shower, toilet, sink - about 200 liters), the number of people living in the house and a three-day supply. If a family consists of four people, then the required volume of the septic tank is calculated using the following formula:
200*4 people*3 days. = 2400 liters
If guests often come to a country cottage, then the result obtained is increased by 2/3:
2400*1.66 = 3900 liters.
The optimal depth of the septic tank is from 1.3 to 3.5 m.
Depending on the final result of the required cubic capacity, according to the table, a tank model is selected:
In this case, the depth of groundwater is important. For a single-chamber model, groundwater must be below the bottom of the tank. For a two-chamber version, they must pass 1 m below the bottom of the last stage (filter). If the groundwater is at a depth of more than one and a half meters, it is technically difficult to equip filtration fields for a three-chamber reservoir, especially on waterproof clay soils.
If household members visit their home on weekends and use a minimum of plumbing equipment, then a multi-section septic tank is not needed. Summer residents, as a rule, prefer low-performance, inexpensive, single-chamber waste heaters. Unlike a cesspool, crushed stone and sand filter layers are poured into such storage tanks, which provide 50% purification.
Experts recommend that it is better to choose a compact two-section mini-septic tank with settling and infiltration chambers. If the volume of drained sewage does not exceed the passport standards, then such a design perfectly performs the functions assigned to it.
Before choosing a small storage septic tank for a country house, you should familiarize yourself with its features:
For the average family that permanently lives in a country house, the best option would be a septic tank with two or three sections, which is a combination of a one- or two-chamber storage tank and a septic tank filter. The first two containers (settlements) are sealed, and the third is without a bottom; a layer of sand and crushed stone is poured into it, which additionally filters the liquid before draining it into the soil.
If the disposal tank is full, it is pumped out by special sewage disposal services; the bio components and filters of the septic tank must be changed every 3-5 years. The multi-chamber settling tank purifies sewage up to 95%.
Which unit should I choose for a home with permanent residence so that the drains are as clean as possible and pumping is done as rarely as possible?
A good option if there is a high groundwater flow limit would be a multi-chamber utilizer with a biofilter. This one is factory. The model, manufactured industrially, consists of 4 sections:
The best choice would be a septic tank with a drainage field that combines several wells and a filtration zone. Such a complex requires an area of at least 30 m2. At the same time, the minimum distance between the sump tank and the house is also at least 30 m.
It is enough to go to a specialized store and see the variety of septic tanks that are offered there, and the consumer will be faced with the problem of choosing the best option. Therefore, we invite you to study the rating of the best non-volatile and non-volatile waste water purifiers, which is compiled in accordance with expert opinion, analysis of sales volume and customer reviews.
TOP 3 non-volatile septic tanks:
Such containers operate without electricity and are suitable, first of all, for country houses with temporary residence.
TOP 3 volatile septic tanks:
These devices require a constant connection to electricity and oxygen supply to microorganisms, so they are better suited for cottages with permanent residence. These are real deep sewage treatment stations with a high degree of efficiency.
All of the listed models of autonomous septic tanks for private homes have proven themselves worthily in the field of wastewater treatment and have a well-thought-out design with a large margin of safety. Therefore, you just have to choose the required volume.
Septic tank - device local sewerage Location on. There are many varieties of systems and types.
These include simple structures made independently and treatment plants. This article should help you in choosing the best septic tank for a private home.
The main purpose is to collect, settle and purify wastewater. They are used in places where there is no centralized system - in dacha areas, outside the city.
There are several parameters by which this component of the local sewage system is classified:
Based on the number of wells, there are single-chamber, two-chamber and three-chamber wells. The materials used in production are steel, reinforced concrete, and plastic. Based on their design, they are classified into storage tanks, with soil purification, and with deep filtration.
Consists of one chamber or two interconnected wells. The waste that enters the hermetically sealed storage facility is divided into liquid and solid. Organic substances are broken down and the liquid settles. To prevent the chambers from overfilling, they should be pumped out periodically.
This option is considered not the most expensive. They are used in dachas where people live only during the season or on weekends. In this case, you can clean it once a year.
Important: storage systems should be used when there is a small amount of wastewater, for example, in dachas, otherwise the cost of their maintenance will be high.
Concrete rings and plastic containers.
In a house with permanent residence and the presence of running water, the best option would be to install an overflow structure. In it, the liquid not only settles, but is also further purified.
This type requires pumping less often. It is cleaned with your own hands every two to three years. To increase this period, special bacteria are used. As a result of their activities, the amount of denser waste is significantly reduced.
The only caveat to using this model is the soil type. It cannot be built on an area with clay soil and high groundwater level.
The decomposition of waste in such a plant occurs in several stages and using various methods. First, liquid and solid waste fractions are separated. Then the denser ones settle to the bottom, and bioprocessing of organic matter occurs.
This model is more of a treatment station equipped with a compressor. It is quite expensive, but it neutralizes up to 95% of waste matter. Installed in areas located near a reservoir or with high groundwater level. During operation, it does not emit any odors.
The principle of operation of a septic tank is based on connection to electrical networks. If the power supply is unstable, the station will not be able to operate.
Some types of modern settling tanks use bacteria. During their life, they absorb waste and contribute to the natural purification of wastewater. According to the principle of operation they are:
Aerobic bacteria purify and clarify the liquid by 95-98%. At the exit from the aerobic system, it meets the requirements accepted for process water. This liquid can be used to water the soil or fill a pond.
An anaerobic septic tank requires constant maintenance. Every two months it is necessary to add bioactivator to ensure wastewater treatment at the proper level. The advantages of using this type include the low cost of construction.
In parallel with the construction of the house, a sewerage system is also being designed. Previously, they didn’t really care about this, and all the masses simply merged into cesspools.
Later they began to be replaced with septic tanks - containers for collecting wastewater from a residential building. To know which sump to choose, you should study all the factors that influence its location on the site.
The type of soil on the site should be taken into account. Some of them are not suitable for use in clay rock, while others are preferable to be installed in sandy soil.
You should follow a few simple rules in your work:
Clay is an unstable material, which requires additional work in installing a sump. At the end of the frost, the structure of the clay changes, it thaws and pushes the structure out of the soil. Therefore, a septic tank in clay rock is equipped with additional metal fasteners during installation.
For containers used in clayey soils, two filtration fields are installed. To do this, two trenches are brought to the sump. In one there are, and in the other there is a layer of gravel, the height of which is up to 30 cm.
An important point when choosing the type of sump is the period of residence at the dacha or in your home. When installing a minimum set of plumbing fixtures, an inexpensive single-chamber storage option is quite suitable.
Despite its simplicity, it is qualitatively different from a cesspool. Sand or crushed stone is poured into the bottom of the storage tank. Thus, a filtration layer is formed that purifies wastewater with a 50% result.
For longer stays, you should purchase a compact two-chamber version. It consists of sections for settling and infiltration of wastewater. The use of this type of equipment is effective if the volume of drainage masses does not exceed its standard value.
Important: When purchasing a septic tank, carefully choose it technical characteristics. Special attention attention should be paid to the number of residents it is designed for.
If you live permanently and have sufficient funds, it is better to purchase a whole station, consisting of two or three sections. It can be factory-made or constructed independently from reinforced concrete rings.
When constructing it, a single- or double-chamber storage tank and a filter section are combined. The settling tanks are made airtight, and the filtration septic tank has a drainage bottom made of sand and crushed stone. The liquid is pumped out from the storage sections using a vacuum cleaner, and the filter is changed every three years. This multi-chamber sedimentation tank purifies wastewater by 90%.
The volume of the device is calculated based on the average daily norm sewerage per person. This figure is 200 liters. Also, when calculating the capacity of the sump, the number of people living in the house and the possibility of accumulating a three-day supply are taken into account. For example, for a family of three people, the volume is calculated as follows: 200 * 3 people * 3 days - equal to 1800 liters.
If guests arrive, the resulting volume should be increased by two thirds: 1800 * 1.66 - equal to 3000 liters.
The recommended depth of settling tanks is 1.3-5 meters. Using these data, their cubic capacity is determined and selected required type. For wastewater volumes up to 1 cubic meter. use a single-chamber version, with a volume of up to 10 cubic meters. choose a two-chamber type if the volume of waste is more than 10 cubic meters. – three-chamber, with a drainage field.
A settling tank with a filtration field combines two or three wells. The drainage zone covers an area underground of at least 30 square meters. The distance from the field to the house is 30 meters.
If the groundwater level is high in the area, it is recommended to install a multi-section septic tank with a biofilter. This model includes four compartments: a settling tank, an anaerobic chamber where large wastes are decomposed, a separator containing a filter with microorganisms, and an aerobic septic tank with forced ventilation.
The performance of the proposed wastewater treatment plants meets a wide variety of needs. There are small options for sale for servicing a family of one or two people, and entire treatment complexes for servicing a holiday village.
Most models of modern multi-chamber devices used in private homes are made from PVC. Products made from stainless steel and fiberglass are often found.
The main advantage of plastic products is their low weight. Their installation does not require the use of special construction equipment. On the other hand, this quality is also a disadvantage, since the container can float or be subject to mechanical impact from the soil. To protect the structure, concreting the walls of the pit and securing the septic tank with belts is used.
The choice of product material determines its service life and operational reliability:
For your information: Fiberglass products are the most practical to use and have a long service life.
For cleaning structures in country houses, factory-made or home-made settling tanks are used.
Options made with your own hands from scrap materials are suitable only for summer cottages with seasonal residence of several people. For a home with permanent residence, it is better to use a purchased installation that guarantees long-term and safe waste disposal.
The use of a two-chamber device allows for primary wastewater treatment and safe disposal of purified water into the soil.
Trouble-free operation of a septic tank requires its maintenance. These works are carried out on our own or with the involvement of specialists.
Simple two-chamber structures, made by hand, are maintained by the home owners themselves. These works include pumping out solid fractions and sludge from the settling chamber, replacing microorganisms to decompose organic matter, and inspecting ventilation and overflow pipes.
The filter layer at the bottom of the leaking chamber should be replaced every three years. This should be done because the bottom becomes silted, which leads to a deterioration in its performance.
By performing these simple operations, you will extend the operation of your local sewage system for several years.
If your home is served by a multi-chamber treatment station, then its disassembly, filter cleaning, and membrane replacement should be carried out by qualified specialists.
The cheapest designs are sedimentation tanks or sewer tanks. If you dig a pit yourself, then the financial costs will only go to purchasing a container for wastewater. The approximate price of septic tanks with a volume of 1.4 to 5.0 thousand liters is 15.0-62.0 thousand rubles.
When installing a local sewer system, the costs include not only the purchase of sedimentation tanks, but also the purchase of pipes, waterproofing, and the purchase of components for.
The cost, consisting of two or three reinforced concrete settling tanks with waterproofing and a cushion of sand and crushed stone, is about 42.0-47.0 thousand rubles. The price depends on the diameter of the rings, their number, and the choice of water purification method.
The used deep biological wastewater treatment plants are expensive. Arranged in the form of combined blocks, equipped with biofilters. They are made of reinforced concrete, plastic and metal. Price from 80.0 to 345.0 thousand rubles.
The standard model consists of four sections: the settling tank itself, a chamber for breaking down coarse waste with anaerobic waste, a separator with microorganisms, and an aerobic septic tank that plays the role of a drainage field.
Designs can be found to meet a wide variety of user requirements. These could also be wastewater treatment plants. Rating:
Available in models whose volume ranges from 2 to 40 cubic meters. Cleaning of coarse waste is carried out twice a year. The service life, if the rules are followed, is about 50 years.
During installation, the walls of the pit are concreted to securely secure the structure.
For small cottages with seasonal residence of one or two people, they use the two-chamber Triton-mini model.
The principle of operation is based on the gradual purification of wastewater using sedimentation and the use of biofilters. The main advantages include ease of installation, high level of purification, and low cost. Cleaning is carried out every five years.
The wastewater undergoes purification in several stages: decomposition of large particles, reduction in the degree of their mineralization, mechanical removal of components. Allows you to purify wastewater by 98%, which is the best indicator. Purified water is used to water the soil.
In order to pick up correct option, you should find out the requirements of its work and study the conditions of the site. Then compare the characteristics of models offered by different manufacturers.

Everything on the shelves:
When building a country house or dacha, the first thing to do is design a water supply and sewerage system. Especially if there are no centralized communications nearby. And in this project, an important role is played by the wastewater disposal and treatment system, for which it is necessary to select the best septic tank for the dacha from all the types offered on the modern market.
The reservoir is a reservoir in which all wastewater from all plumbing points of the house is collected and undergoes biological treatment, followed by drainage of the liquid into the soil or pumping it out using sewage disposal equipment.
In order to understand which tank to install at a specific summer cottage, it is worth conducting a thorough analysis of all types of equipment, understanding the principle of their operation and assessing the feasibility of installing one or another type of treatment system for private sewer.
We analyze the types of septic tanks in our material and find out which tank is the best.
The modern plumbing industry offers consumers septic tanks, which can be classified according to several criteria. First, we will analyze the treatment systems according to the method and principle of operation, conducting a thorough analysis. There are these types of septic tanks:
More details about each type of equipment below.
This type of private sewer equipment provides a durable, sealed tank for storing all domestic wastewater from the site. In principle, such a container resembles a standard one cesspool, with the only difference that the storage septic tank does not have walls in the form of soil. In this case, when installing a treatment system, the tank is simply buried in the ground to the required depth.
The principle of operation of such a treatment system is that wastewater is collected in containers where natural decay of the wastewater occurs. That is, their larger and heavier particles settle to the bottom of the tank, and lighter water and fatty films rise upward.
Such a structure requires periodic cleaning using a vacuum cleaner.
Important: when analyzing, selecting and installing a storage septic tank, you should carefully select the container according to its volume and material of manufacture. In the first case, the volume should allow the unhindered accumulation of a certain amount of wastewater over a specific period so that it is not necessary to frequently call in special equipment to remove it from the tank. As for the material, it must be strong enough so that it is not crushed by the soil during operation. A thorough analysis is also recommended for this purpose.
Most often, the device of such a septic tank is used in dachas or country houses, in which people live not permanently, but for seasons.
These types of septic tanks are used in those houses where households are expected to live permanently and where the amount of wastewater will be the same constant. This type of equipment requires less frequent cleaning using special equipment.
The operating principle and design of such a treatment plant are quite simple and are as follows:
Important: in order for the bacteriological decomposition of wastewater in such a treatment facility to proceed faster, it is better to use special aerobic bacteria, which will not only process the wastewater, but also eliminate its unpleasant odors from the septic tank.
After analyzing septic tanks, we were able to identify the following advantages of this type of equipment:
Important: these types of septic tanks are prohibited from being built and operated in areas with clay soil or in areas where groundwater is located high. In this case, instead of draining into the soil, all the runoff will simply begin to wash away the area.
These types of septic tanks are widely used in almost all areas and at any facilities. The main feature of such a device is high-quality wastewater treatment to the state of water that is safe for the environment. Residual organic matter can be discharged from such a treatment plant directly into the ground or even water bodies. This is evidenced by a qualitative analysis of water sampled from a septic tank of this type.
Settling tanks with a biotreatment system use complex wastewater treatment:
The operating principle and design of such a treatment plant are as follows:
Important: in order for aerobic bacteria to work more efficiently, a special compressor is installed in the second chamber of the septic tank, pumping oxygen.
After the organic masses acquire a structure that is simple in composition, they are transported to the third chamber, in which chemical purification of the water is carried out. Now the wastewater is ready to be discharged into the ground or reservoir.
According to the analysis of all three types of containers, this one has the following advantages:
Important: a septic tank with a deep purification system requires connection to the electricity network, which entails the need for additional payment costs utilities. But, after comparing all three types of septic tanks, we can safely say that such expenses will more than pay off in the absence of the need to use sewage disposal equipment with enviable regularity.
All treatment tanks can also be divided into categories and according to the type of material used for their manufacture. Since the use of certain types of containers is relevant for one type of soil and may be completely unsuitable for another. Therefore, it is necessary to analyze all the containers offered by the market.
So, we compare septic tanks by type of material. The reservoirs are as follows:
The most standard type of treatment tank in a summer cottage or suburban area. The popularity of such containers is due to the ability to use waste building materials, which allows saving the family budget.
When building a septic tank from brick, it is necessary to ensure the tightness of its walls, since building stone can create cracks and gaps during installation. To avoid this, you can use a sealant or penetrating mastic.
Important: in addition to saving money from the family budget, such a treatment plant is quite profitable from the point of view of its construction. There is no need to use complex equipment or professional skill. You can lay one brick with your own hands.
A feature of the construction of concrete tanks is the need to dig a pit. If the septic tank is very large, you will have to use complex equipment.
Two types of treatment facilities can be built from concrete:
In the first case, a pit is dug and reinforced concrete is poured into the installed formwork. In the second case, the septic tank is assembled from concrete rings. They are mounted one on one.
Important: for containers made of reinforced concrete rings, it is necessary to ensure the tightness of the joints.
Most rare view tanks for wastewater treatment. Analysis shows that such containers have more negative features than positive ones. And the most important of them is metal corrosion, which will one day lead to depressurization of the cleaning system.
A comparison of septic tanks made of different materials clearly speaks in favor of plastic. Such containers are made from sand-reinforced polymers using the hot extrusion method (extrusion under high pressure). The result is a strong container that can withstand large mechanical loads of compression and tension. Especially if the tanks have special stiffening ribs.
The features of such tanks are entirely positive:
The last advantage can also play the role of a disadvantage. Thus, plastic containers for a septic tank run the risk of being thrown out of the ground under the influence of temperature changes and groundwater. To prevent this from happening, they (PVC tanks) are installed in special pits, followed by concreting. You can also use a special anchor system to install them.
There are also septic tanks made from any available materials. But this type of equipment is not professional and is most often used in small dachas, where the owners come periodically to harvest crops or prepare for the winter. In this case, simple barrels, car tires, etc. can be used.
Based on the type of construction, septic tanks are divided into one-, two- and three-chamber ones. The latter are carried out if it is planned to install a treatment plant with a biological treatment system.
Two-chamber tanks are tanks for a wastewater treatment plant with a ground cleaning system. Single-chamber septic tanks are storage tanks.
All septic tanks can be divided into vertical and horizontal according to the method of installing the cameras. So, in the first case, the containers are installed with their bottom in the ground and look like a simple barrel with hatches in the upper part. With this installation method, the treatment system goes deeper and takes up less space on the site.
If the septic tank is installed vertically like a tank, then, on the contrary, the depth will be less than the occupied area.
Important: vertical treatment structures are used where the groundwater level is high enough.
In addition, it is worth noting that septic tanks can be surface or underground. The former are also used on those soils that are washed by a large amount of groundwater located close to the surface of the earth.
Underground - installed in all other cases.
Which types of septic tanks to choose for a dacha or country house, and which options are suitable for your site, must be decided depending on the following parameters:
Remember, a correctly selected and installed septic tank will effective means for cleaning and draining all domestic wastewater.
Can't connect to the central sewer? You can solve the problem locally - install a septic tank. To make this task easier, we have prepared a review of 9 reliable septic tank manufacturers. There is a good chance that other companies you come across are either copying or counterfeiting these 9 products.

All models treatment systems Tver - energy-dependent installations for seasonal or permanent residence. Polypropylene with a thickness of 5 mm is used as the material for the walls of the containers. The rigidity of the structure is ensured by stiffening ribs and internal partitions.
* There are 7 more modifications of this station, for example, the model with the PN index has a pump compartment with a submersible pump for forced supply of treated wastewater.
The video below provides detailed information about installing a Tver-0.75 PN septic tank. A company representative at a real site explains the structure of the system and the role of each of its elements. Station maintenance is described in detail. If you are thinking about buying this model, be sure to check it out!
Conclusions: Trade House "Engineering Equipment" does not offer a large selection of systems for country houses. The guys simply developed a model that works well and scaled it up. The result is not the most compact water purification station in terms of average price. The main thing is that it works, right?
All the presented manufacturers are good, but we especially want to highlight the following:
Here we have collected answers to pressing questions about septic tanks.
What material is the best septic tank?
Factory products for individual use are made from polymer materials: polypropylene, low-density polyethylene (HDPE), fiberglass. They are relatively light, do not corrode, are strong, sealed and durable - all these materials are good.
The only question is to what extent their capabilities are realized in a particular septic tank design. For example, there may be a polypropylene container in which the seams are welded poorly, so it will leak after some time.
The rigidity of the structure is influenced by the thickness of the material and the presence of structural elements: stiffeners and internal partitions. Therefore, if the design is unsuccessful or simply does not suit specific operating conditions, the septic tank can be flattened or torn apart by soil. But the point here is not in the quality of the material from which it is made, but in the design itself.
I can’t decide between a non-volatile septic tank and a biological treatment station with aerators. What's better?
If for a summer residence, choose a non-volatile sump tank, provided that the groundwater level is below 1.5 meters, and the soil itself has good filtering abilities. For example, it is sand or sandy loam. Once a season you will have to do dirty work and remove accumulated sludge from the bottom of the tank, but in general this solution is the most economically feasible and convenient for seasonal living.
For private homes, it is better to buy a system that ensures maximum purity of wastewater leaving the treatment plant. You can’t do without a station with aerators. One of the advantages: the wastewater does not smell after it, it is cleaned so much that it can be poured into roadside ditches. However, this solution is more expensive, and automation and compressors require connection to the electrical network.
Summer cottage near the forest, seasonal accommodation, four people. Recommend a septic tank.
If you need something cheaper and simpler, then consider the Termite Pro 2.0 option. It is very similar to the well-known Tank, but costs only 39,000 rubles. The manufacturer also often has promotions - you can save several thousand.
The filtration field can be set up next to the forest. This is where you will dump wastewater for further treatment. This way you will cause minimal inconvenience to yourself and your neighbors.
At the dacha there is a well from which water is used for food purposes. Which septic tank to choose?
Obviously, a treatment station is required here, after which the wastewater can be discharged into a roadside ditch. If there is no ditch, it can be lowered into the ground, provided that the discharge point must be 50 m from the well.
If the soil does not accept water, then in some cases it makes sense to think about installing a storage tank and then calling the vacuum cleaners.
Will the drains freeze in winter? Is it necessary to insulate a septic tank?
If used constantly, they will definitely not freeze - a kind of bioreactor is constantly working inside, generating heat. In extreme cases, you can insulate it by pouring a layer of straw or leaves on top.
During seasonal use, it is recommended to fill the container 2/3 with drainage, additionally insulating it on top. This way the container will not float up and be crushed by frozen soil. We recommend that you additionally read the instructions for the specific model; the manufacturer may have a different opinion on this matter.
What happens to a volatile water treatment plant if the power goes out?
Typically, such systems are very sensitive to power outages. The compressor pumping air stops working, and after 6 hours the amount of oxygen in the wastewater is significantly reduced. The struggle begins between aerobes and anaerobes. Effluent can begin to ferment due to anaerobes, so after turning on the electricity, normal operation occurs within several days.
Is there a strong smell from the septic tank?
After a regular septic tank there is a strong, characteristic smell of sewage. It can be felt even close to the filtration field, so they are installed in the most remote place.
After systems with aeration, the water is cleaner and does not smell. Unless the station's operating mode is disrupted: exceeding the permissible peak discharge, power outage, use of aggressive detergents.
Installed a septic tank with a filtration field without connecting to the power supply. How to service it?
Once every six months it is necessary to open the container and check the amount of sediment. If it is more than 1/5 of the height of the container, it will have to be removed. Use a bucket or fecal pump for this purpose.
Light fractions will accumulate on the surface of the wastewater. If they form a thick, hard layer more than 5 cm thick, it is also better to remove it in a timely manner, because it can subsequently significantly complicate cleaning the tank.
