The choice of a septic tank for a country house comparison. Septic tanks for summer cottages - what is it and how to choose the right model. What to consider when choosing a septic tank

Owners of private houses often face the problem of wastewater disposal due to the lack of a centralized sewerage system outside the city. For a long time, the only way out was to dig a cesspool, but using it is quite inconvenient and costly. Now they are mainly trying to mount an autonomous wastewater treatment unit - septic tanks for summer cottages, but still 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 analyze in detail the question of which septic tank is right for you and discuss the best options based on the tasks that it must solve.

What are septic tanks and what are they

Some mistakenly call a septic tank a complete set of treatment equipment. In fact, this is only a part of the treatment plant, which acts as a reservoir and primary filter for wastewater containing a large amount of biomaterials that require disposal.

There are quite a few varieties of septic tanks, and each of them has its pros and cons. Therefore, before purchasing, it is necessary to take into account what soil the country house stands on, the amount of water consumed and, of course, the budget that can be allocated for the purchase and installation.

Briefly about septic tanks on video:

Also on initial stage it is necessary to decide on the type of device - to purchase a non-volatile septic tank or in which a forced supply of wastewater is organized (volatile). The first, by and large, are ordinary tanks for surface (within 60%) mechanical wastewater treatment, and the second are equipped with a pump and a set of additional filters, after which the output is process water purified by 95-98%.

It is possible to correctly decide which septic tank to choose - for year-round use or able to work effectively even with periodic supply of effluents, you can do it yourself, since there is enough information. Many turn to the help of the Internet for such queries as the rating of septic tanks for country house 2017, to get acquainted with the various ratings of septic tanks. But if there are doubts about the correctness of the choice, then the best option would be to turn to professionals. They will take into account all the nuances and select suitable option tailored to specific tasks.

Cleaning steps

Wastewater goes through several stages of treatment in a septic tank:

Stage of accumulation and settling. This stage consists in 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 vapors (carbon dioxide and methane) are vented to the outside. At this stage, there is a partial stratification of wastewater, which is then sent to the next tank;

Secondary filtration stage. Its goal is to clean the mixture up to about 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, the sorbent has to be washed and reactivated annually to work correctly;

Solid deposits settled in the tanks are pumped out or removed mechanically.

Operating principle

Technically, two types of waste disposal are used: anaerobic (without air access) and aerobic (decomposition involving bacteria that need oxygen for life).

Septic tanks have an anaerobic mechanism of action, which act as a storage tank or sump. Such treatment systems, without installing additional equipment, carry out only primary clarification of wastewater and require their frequent pumping out by a sewage 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 cottages or private houses with a small number of residents. The cost of such a structure is low, the installation does not require much effort, and the operation does not require a constant flow of effluents into the chambers.

Often colonies of active bacteria are added to such septic tanks, which help to filter effluent better than with conventional anaerobic treatment.

The aerobic mechanism of action is carried out by local biological treatment plants. Colonies of aerobic bacteria are settled in such septic tanks, which effectively clean wastewater.

Unlike anaerobic crops, they reproduce rapidly, have a wide variety of species, and are 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 vital activity of bacteria. Also, aerobic systems must constantly work - if within 2-3 weeks there is no new effluent entering the chamber, then the bacteria will die and their cultures will have to be planted again.

Obviously, the best septic tank for a country house is aerobic. But it all depends on the budget, as this type of treatment plant is more expensive.

What materials are septic tanks made of?

An important aspect when buying a septic tank is the choice of material from which it is made. Most often, when ordering a finished septic tank, it is made of polymeric 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 a lot of money and time. It is mainly used in the construction of septic tanks with their own hands;

Fiberglass structures are the most suitable and frequently used material.

Also, septic tanks can be made from improvised materials (barrels, tires) on their own, but this option is only suitable for small country houses.

You can save on the purchase of a cleaning plant by placing an order at the factory. The most expensive on the market are septic tanks with additional equipment for complete biological wastewater treatment.

Volatile and non-volatile septic tanks

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 need periodic pumping of waste by a sewage machine. They have a low degree of purification and require additional ground filtration, for which it is necessary to allocate a piece of land. The positive aspects include low cost and independence from electricity;

Volatile septic tanks are the exact opposite of non-volatile structures. Thanks to the design and additional equipment, wastewater in such systems goes through a full cycle of processing and purification, which eliminates the need for maintenance. The disadvantages include the cost of installation, as well as dependence on electricity. During the absence of power supply, the degree of purification of sewage water decreases, and the septic tank acts as a sump.

Criteria for choosing a cleaning system for a country house

Before choosing a suitable septic tank, the following aspects must be considered:

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 relief of the area where the installation of the structure will be carried out and the height ground water;

The complexity of installing a sewage treatment system - septic tanks with a filtration field are leading in terms of installation costs, and biological treatment plants are the most profitable in this regard - their capacity just needs to be buried in the ground;

Own budget.

A few more words about the choice of a septic tank on the video:

Conclusion

Depending on the budget, you can make a cleaning system yourself from improvised means, 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 right choice, since you need to take into account all the features of your site and the requirements for it.

A properly selected and correctly installed septic tank will create the conditions necessary for a comfortable stay in a country house.

The septic tank has long gained popularity among owners of country houses. This is a much more practical and safer treatment plant than cesspool, to which many summer residents are so accustomed. The design of septic tanks includes chambers where wastewater is settled, cleaned and recycled. Thus, water becomes safe for the environment. And the principle of operation of septic tanks is that from the house they lay sewer pipes and connect to the device.

A septic tank for a summer residence periodically requires cleaning. Depending on the type of construction, cleaning is carried out every one to five years. A septic tank will be a suitable sewer option for suburban area. You will find detailed information on installing, conducting and connecting sewers in a private house at http://marisrub.ru/uslugi/inzhenernye-sistemy/kanalizatsiya.

Released today different kinds septic tanks for a country house, which differ in performance and volume, material of manufacture and other parameters. Let's find out the selection rules and consider the rating of septic tanks for a country house.

Types of septic tanks

They produce volatile and autonomous septic tanks, models of horizontal and vertical arrangement, devices that differ in the type of work. In the latter case, accumulative models are distinguished, devices with soil filtration and deep cleaning.

A storage septic tank is the most affordable option, representing an improved cesspool. Wastewater enters the tank and is separated into fractions into storage tanks. The septic tank is cleaned as it fills up.

This model is characterized by accessibility, easy installation and not high price. However, they are not very user-friendly and require frequent cleaning. The accumulative design is suitable for giving, which is used for seasonal living and housing.

Septic tanks with soil filtration and post-treatment are suitable for those who constantly live outside the city. In such a device, wastewater is cleaned, and not only accumulated and divided into fractions. Structures with post-treatment can be cleaned once every two to three years. By the way, to increase the time between cleanings, special bacteria additives are used for septic tanks.

The design with soil post-treatment consists of two chambers. Such models are characterized by ease of use and maintenance, but they are not suitable for installation in areas with clay soil and increased level ground water.

Septic tanks with deep cleaning purify and disinfect water by 90-100%, so drains without the risk of pollution environment disposed of in the ground. The system is distinguished by versatility and a high level of wastewater treatment, no odors and easy installation.

A septic tank with deep biological treatment does not require regular cleaning and constant monitoring of the operation of the device. Cleaning is carried out no more than once every five years. This is the right choice for country cottage where they live permanently. Among the minuses, we note the high cost of equipment and installation, but there are practically no additional costs during subsequent operation.

In addition, septic tanks are divided according to the type of material. The equipment is made of plastic, metal, brick and other raw materials. The most affordable and popular are plastic models, which are characterized by high strength and tightness, light weight and installation, corrosion resistance. But when installing such a design, there is a risk that the container will suffer when the soil moves.

Brick septic tanks will not provide proper sealing, so additional waterproofing is required during installation. But reinforced concrete septic tanks will become a reliable device that will last a long time. Experts do not recommend installing metal models, as they are prone to corrosion, which reduces the lifespan.

How to choose the right septic tank for a summer residence

If the suburban area is located in warm regions or in middle lane Russia, choose plastic products. For the northern and cold regions, it is better to choose reinforced concrete structures that tolerate frost, temperature extremes and humidity;
For year-round living in a country house, a septic tank with deep biological treatment is well suited; for seasonal stays in the country, standard storage models are more often used;
Each model is characterized by a certain performance. You can easily calculate the desired performance by multiplying 200 liters by the number of people who permanently live in the house. Where 200 liters is the approximate volume of water that one person uses per day;
If the house has two or more bathrooms, then the volume of the tank should be larger. Consider how many people permanently live in the room. Yes, for one-story house with one bathroom and with 3-5 people living all year round, a septic tank with a volume of 2-3 m3 is suitable;
Examine the characteristics and opinions about the work of the model. Next, we list best septic tanks for a country house: rating, which is based on reviews of buyers and experts.

Experts call the Tank the best autonomous septic tank. Among the devices that depend on electricity, largest number positive feedback collected Poplar. But remember that the choice is influenced by the amount of water consumed and the number of bathrooms, the type of residence in a country house and the characteristics of the soil.

Experienced craftsmen will tell MariSrub which septic tank to choose for a summer residence. We will select a durable and airtight model, perform installation reliably and promptly, connect sewerage and other engineering systems in a private house.

Already in the early stages of the project wooden house we carry out the necessary calculations for the installation of each engineering system, including water supply and sewerage, ventilation and electrical wiring, heating. As a result you will get reliable system which will work for many years without problems!

If you try to decide which septic tank is best for a summer residence with non-permanent residence, then you will quickly realize that you cannot find a definite answer here. Family budget, "productivity", geological features of the site - this is an incomplete list of selection criteria, therefore, in each individual case, something different will be the best solution. But in any case, the very nature of seasonal residence already imposes some restrictions of a fundamental nature on the choice of design.

There are universal solutions, but they also have certain limitations. Source skopelitissa.com

Classification of septic tanks

According to the principle of operation of a septic tank, there are the following types:

Cumulative. If you approach strictly, then this is not a septic tank, but simply a container for collecting wastewater, the prototype of which is a cesspool. Previously, there were no special requirements for the tightness of the walls and bottom of such an underground reservoir. Now this is a mandatory condition, non-compliance with which is prosecuted as damage to the earth. Therefore, instead of a “pit”, a finished container is buried in the ground or it is made of reinforced concrete (prefabricated or monolithic).

Anaerobic. This is a classic example of an underground local treatment plant, where effluents are separated and processed by bacteria in the process of flowing from chamber to chamber without oxygen. The degree of purification reaches 60-70%, and clarified effluents undergo post-treatment with aerobic bacteria in filtration fields, trenches or wells.

Aerobic. The design is built in such a way that inside the septic tank there is a complete cycle of wastewater treatment with aerobic bacteria up to a level of 95-98%. This is a volatile species, since forced air supply is necessary for the vital activity of microorganisms.

Advantages and disadvantages of septic tanks in summer cottages

Each species has its own set of advantages:

A storage septic tank for summer living is now one of the most popular options. The advantages include: low price, simple device, the ability to accept all types of wastewater, regardless of their "acid-base" balance. It is not subject to the regulations for minimum distance from water sources, a residential building and the boundaries of the site - the drains for the entire period between pumping are inside a sealed container.

The only drawback is the need to frequently call a sewage truck, the periods between the arrival of which depend on the volume of the septic tank and the intensity of operation. The load on it can be reduced, the duration of work without pumping can be increased if the drains are divided into gray and black, and the drain of water from the shower cabin, bath and from the washbasin is brought into your filtering or drainage well.

Effluent from a storage septic tank without electricity has to be periodically pumped out Source strojdvor.ru

An anaerobic septic tank consists of two or three chambers connected in one building or spaced apart in separate tanks. The correct selection of the volume of the chambers and their relationship to each other regulate the productivity and degree of wastewater treatment to a “clarified” state, which allows them to be diverted to soil treatment and filtration devices.

Anaerobic septic tanks are non-volatile. The entire liquid part of the effluent is eventually discharged into the ground. They clean the containers only from solid fractions that settle at the bottom of sealed chambers in the process of separation and processing by bacteria. The frequency of pumping out can be from several months to several years - it depends on the volume of wastewater, the number of residents and visitors, and the length of stay. This is the best option for a septic tank for a non-permanent residence without electricity (even when it is). But provided that the size of the site and its plan allow installation without violating the requirements of the standards.

The main disadvantage is the rather strict requirements for the location of the water intake, reservoirs, residential building and site boundaries. In addition, when arranging filter fields and wells, there are restrictions on the type of soil and the depth of groundwater.

In some cases, a pump is used to remove treated effluents. Source otepleivode.ru

On our website you can find contacts of construction companies that offer the service of design and installation of sewerage and water supply. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".

An aerobic septic tank, despite the almost complete wastewater treatment, is rarely used to give non-permanent residence. To create conditions for the vital activity of microflora that process wastewater, a constant air supply is required, which is provided by the operation of the compressor.

When the electricity is turned off, aerobic bacteria die, and to start the septic tank, a fairly large amount of work must be done to prepare the system.

Another reason against interruptions in the functioning of an aerobic septic tank (even if the compressor is running) is the death of bacteria in the absence of "fresh" effluents containing organic matter, which serves as a food medium for them. But this is not the main drawback. According to the manufacturer of septic tanks Topas, it takes 2-3 weeks to reach the design level of cleaning after launch. That is, if they live in the country in the summer, then it must be started in the spring, and turned off in the fall.

For the same reason, such a septic tank is not suitable for work in winter with intermittent residence in the country, when people come here only on weekends.

For the vital activity of bacteria that live in an aerobic septic tank, a constant influx of effluents is necessary - during long interruptions in work, the colony of bacteria will have to be repopulated Source repair-book.com

Combined septic tanks. A design of this type provides for at least two sealed chambers (in practice, at least three). In the first chamber, separation into fractions and clarification of effluents with the help of anaerobic bacteria takes place, in the second - cleaning with aerobic bacteria.

The advantage of this configuration over the previous version is considered to be higher productivity and less load on the biological phase of purification by aerobic microorganisms. But these are volatile models that have the same disadvantages as septic tanks for giving non-permanent residence.

Septic tank materials

In both types of septic tanks for giving non-permanent residence, there is always a container with a sealed bottom and walls.

Polymer septic tanks

If you choose among ready-made models, then septic tanks are made of durable polymers that are not subject to corrosion and can withstand prolonged exposure to an aggressive environment. These include polyethylene low pressure, polypropylene and fiberglass.

All factory containers are designed for a certain pressure both from the inside when filling with drains, and from the outside as a result of soil pressure - the wall thickness and a set of stiffening ribs guarantee shape stability.

Most often, factory septic tanks are made on the basis of plastic containers. Source alfa-septik.ru

Each type of polymer has its drawbacks, but they are not fundamental. home common feature- small weight of capacity. Even when full specific gravity the septic tank, taking into account the solid fractions of effluents, does not exceed 1100 kg / m 3, and the soil even has a bulk density of at least 1500 kg / m 3, not to mention the compacted state in natural form. Therefore, heaving forces will tend to push the septic tank up, especially if it is empty. When installing plastic septic tank, it must be fixed to a solid foundation in the form of a concrete slab. And on strongly heaving soils, it is recommended to backfill the pit with excavated soil mixed with sand.

Note! In any case, during a long break, the container should not remain empty. The standard recommendation for a period of absence is 3/4 fullness so that the walls can better hold the pressure of the soil, and the colony of anaerobic bacteria does not completely die out.

Metal septic tanks

Polymer septic tanks have replaced metal containers, but they are still found. Among the offers on the market of metal septic tanks there are three types of containers:

factory products with fixed characteristics;

production under the order according to the individual sizes;

sale of used steel tanks and tanks for technical liquids, which are being modified for a storage septic tank.

Unlike polymer tanks, such tanks have a large margin of safety: the minimum metal thickness is 4 mm, and for large volume tanks - 8-12 mm. But the service life of metal septic tanks summer cottage, even under the condition of anti-corrosion treatment, is lower than that of plastic ones.

Reinforced concrete rings

One of the most popular materials for arranging sewerage for non-permanent residence is reinforced concrete rings KS series. They are different diameters and heights that allow you to make the design of the optimal volume.

Advantages - high strength and stability in the ground. Concrete has a tendency to get wet during prolonged contact with a humid environment, but this disadvantage is compensated by a waterproofing surface treatment.

Installing a septic tank is a little more complicated than installing a finished tank. Basically, it's a team. reinforced concrete structure from several containers, each of which consists of several rings (including a filter well without a bottom with perforated walls). But in each region there are construction organizations specializing in such a turnkey service.

The choice of the volume of the septic tank

With the volume of the storage septic tank, everything is very clear - the more, the less often you have to call the car to clean it. And if we divide the drains into black and gray, then a tank of medium volume will be enough to give a “day off” for the whole season.

An example of the separation of drains into "black" and "gray" Source 1bcm.ru

The shape and dimensions of the storage septic tank are dictated not only by the required capacity, but also depend on the free space on the site, which would provide free access for the car to the technological hatch. Standard Location- somewhere in the middle between the wall of the cottage from the side of the bathroom and the border of the site adjacent to the road. There are usually no problems with the depth of the tank - power vacuum pump sewage machine guarantees pumping sewage from a depth of up to 4 m.

The volume of a septic tank without pumping out is determined by a simple formula - the number of people is multiplied by the rate of water consumption of 200 l / day and a factor of 3 (so many days it takes for a cycle of disinfecting wastewater with bacteria). Sometimes they add 20-25% for a “volley” discharge when guests arrive. This total volume is distributed among the chambers. For a two-chamber septic tank (excluding the filter well), at least 2/3 is given to the first tank, for a three-chamber septic tank - at least ½.

Conclusion

No matter how simple a septic tank may seem to give non-permanent residence, it should be installed by professionals. Especially if it is an anaerobic septic tank. And the difficulty is not even in the installation itself, but in the choice of methods for soil wastewater treatment. Specialists will take into account the geological features of the site and the filtering capacity of the soil as fully as possible.

It is easy to get confused in the abundance of offers on the septic tank market. Manufacturers respond to growing demand and offer autonomous treatment facilities for absolutely any request. How to choose the right septic tank? You just need to limit the choice to the most famous brands that have already earned a good reputation among users. We decided to help you with this and made a TOP list of autonomous sewers. We have chosen those septic tanks and stations that are widely represented on the market.

A septic tank is commonly referred to as any suburban sewerage system. This is not entirely true. There are septic tanks, settling tanks, and there are biological treatment plants. These are completely different treatment facilities.

How is a septic tank different from a station?

The first difference is the quality of cleaning. The water from the septic tank comes out cloudy and with a characteristic odor. From the station, odorless process water, purified up to 98%, is drained.
The second difference is that the water after the septic tank needs to be further cleaned in the filter well or in the filtration field. After cleaning in the station, it is allowed to divert the runoff to the terrain, for example, into a ditch.
The third difference follows from the second. Septic tanks are not suitable for clay soils and high groundwater. Under such conditions, soil post-treatment will not work and, therefore, a septic tank cannot be installed. For biological treatment plants, this is not a problem.
And fourth. Septic tanks are most often made of fiberglass or polyethylene, and stations are made of polypropylene. Polyethylene is plastic and dents under soil pressure. Fiberglass septic tanks are very durable, but due to the peculiarities of manufacturing (molding) they can be leaky. Cases of stations made of polypropylene, as practice shows, are very reliable.

Let's just say that this rating is subjective. All estimates are based on our own experience in the installation and maintenance of septic tanks and stations in different regions Russia (NWFD, CFD, Urals) for 8 years. In total, in our review there are 17 septic tanks and bio-treatment stations that we installed and for which we collected statistics. Let's start the rating with the most problematic septic tank and get to the best.

17. Station Kolo Vesi

In last place is the sewerage of Colo Vesi. This is a biological treatment plant, which is positioned as a Finnish one, although all production is located in Russia. Kolo Vesi belongs to the type of stations in which there is no compressor, and aeration (saturation of wastewater with oxygen) occurs when water is sprayed over the bio-load in the neck of the installation.

Characteristics:

Manufacturer: Kolomaki
8 mm
Degree of purification on a five-point scale: 1
Price: very high
Maintenance: pumping out with a cesspool every 1.5-2 years (but preferably more often, with permanent residence, a smell quickly appears)
Warranty: 1 year

Why buy:

The body is cylindrical, well withstands squeezing. There are lugs on the body, so the septic tank is suitable for problematic soils.
The drain circulates by gravity, respectively, you can not be afraid of clogging the station.
The wires are connected in the control box outside the station and if the station is flooded, the electrics will not suffer.

What to consider:

Aeration when pumping wastewater through a biofilter is considered less efficient than compressor aeration. Manufacturers of Kolo Vesi do not work on this shortcoming (for example, there is additional ejector aeration in the Eurolos BIO septic tank).
We think that the Kolo Vesi septic tank does not have enough volume for deep wastewater treatment. Recently, complaints about this sewerage system have often been received.
Sprinkling during installation must be done by DSP. This is a manufacturer's requirement, and it increases the cost of installation.
Kolo Vesi is one of the most expensive stations, despite its controversial reputation.
The septic tank is positioned as Finnish, although it is produced in Russia. The Finnish technology, which is implemented in the septic tank, in this case is a minus, since European cleaning requirements do not correspond to Russian ones. The prototype for Kolo Vesi was indeed the Finnish Green Rock septic tank, but it is produced to different standards, with lower requirements for the quality of cleaning.
Infrequent and simple maintenance is claimed, but due to insufficient volume and the appearance of a smell, the station has to be serviced more often.
This is the only station that our company receives complaints about. They are mainly associated with smell.

For sites with any soil conditions.
For country houses with a small volume of drains, which this septic tank can handle. Experience shows that if the station is chosen with a margin, then it does not produce an odor. Unless, of course, open the lid.

Conclusions:

In essence, Colo Vesi is a marketing bubble. In terms of cleaning quality, this is, at best, a septic tank with a biofilter (except in a beautiful case). Due to frequent complaints from customers at a very high price of this septic tank, we put it in last place in our rating. We are not dealers of the manufacturer Kolo Vesi, we do not sell and do not recommend this sewer to customers.

The cleaning technology used in Kolo Vesi has advantages. But I recommend taking a closer look at the Eurolos Bio station (9th place in our septic tank rating). The volume of this treatment is larger, there are no complaints about the smell and Eurolos costs almost 2 times cheaper than Colo Vesi.

16. Septic tank Termite Profi

Polyethylene septic tank from an experienced manufacturer. Like other plastic septic tanks, Thermite works well in dry soil with a low GWL. Waste water is settled and discharged into a drainage trench, into a filtration field or into a filter well.

Characteristics:

Manufacturer: Multplast
Type: septic tank
Material: low-density polyethylene, the body is made using rotational molding
The degree of purification on a five-point scale: 1 point
Price: low
Alarm: not required as there is no electrical equipment in the septic tank
Service: 1 time in 1.5-2 years, for pumping order a sewage machine

Termite Benefits:

The case is made using rotoforming, it is one-piece cast and without seams.
A bioload is provided, which reduces the leaching of microflora and improves the quality of cleaning.
The septic tank itself is inexpensive.
The operation of the septic tank does not stop when the electricity is turned off, it is non-volatile.

What to consider when choosing:

The body of the septic tank is in the form of a parallelepiped, the pressure on it is uneven, the septic tank can be deformed, especially if it is chosen incorrectly (for clay and high GWL) or the installation technology is violated (sprinkling an unfilled septic tank or pouring an unsprinkled one).
Sprinkling is done by DSP and it is longer and more expensive than sanding.
After cleaning, the smell remains, additional cleaning in the ground is required. But this is a feature of all septic tanks.
The manufacturer does not give a guarantee for the septic tank. If a manufacturing defect is found, you may have to use consumer protection law.

Owners of sites with dry sandy soil and low GWL.
Those who are looking for budget sewerage, the quality of which can be trusted.

Conclusions:

A cheap septic tank with restrictions on the conditions of use (sand, sandy loam, low GWL). The case is plastic and does not withstand strong squeezing by the ground. In addition, the lack of a guarantee is surprising. We give this septic tank the penultimate 16th place.

15. Station Ergobox

Biological treatment station from the same manufacturer that produces the Termit septic tank. In fact, this is a modified Termite Transformer septic tank. It has a compressor and an aeration element. Water is saturated with oxygen and conditions are created for deep biological purification.

Characteristics:

Manufacturer: Multplast
Type: biological treatment plant
Material: low-pressure polyethylene, manufacturing technology - rotational molding.
Degree of purification on a five-point scale: 2 points
Price: below average
Alarm: not provided, installed at the request of the customer
Maintenance: 1 time in 1.5-2 years pumping out with a cesspool
Warranty: no official warranty

Why buy an Ergobox station:

It is inexpensive compared to other aeration stations. Complete with cheap Hailea compressors and Gileks pumps (if the withdrawal is forced)
Light weight and easy to install by hand.
The drain overflows from chamber to chamber by gravity, clogging is almost impossible.
Made on the basis of a septic tank, but it performs deep cleaning and does not require filtration fields and drainage wells.

What to consider:

During installation, the station is sprinkled with a cement-sand mixture. Installation is expensive and difficult.
To pump out the sediment, you need to call a sewer. Pumping is done infrequently (once a year), but it costs money.
The cleaning quality is not very high.
The station is not guaranteed.

If you need the most budgetary biotreatment station
If there is no place on the site for a filtration field or a drainage well, or you don’t want to service these structures in the future (crushed stone silts up and is changed every few years)
If there are pets in the country house. Wool in this septic tank does not lead to blockages

Conclusions:

The station is inexpensive, but with poor cleaning performance. The body is plastic and unreliable, so it is sprinkled with DSP, and this is an extra cost. Cesspool calls are not cheap. There is no manufacturer's warranty. The Ergobox station is optimal only in cases where the budget is limited, and a septic tank cannot be installed due to the conditions on the site. Because of all these shortcomings - only 15th place.

14. Station BioPurite

Station with compressor aeration and gravity overflows, as in a septic tank. BioPurite has been produced by the Flotenk plant for more than a year, it has changed its design more than once, and today the manufacturer continues to improve this septic tank.

Characteristics:

Manufacturer: Flotenk
Type: biological treatment plant
Material: machine wound fiberglass
Price: average
Emergency signaling: not provided, can be installed as part of additional developments
Maintenance: 1 time in 1.5-2 years with a vacuum cleaner
Warranty: 1 year

Why buy:

The body of BioPurita is made by machine winding of fiberglass. It is an extremely durable material that is not afraid of ground pressure.
Grousers (protrusions around the bottom of the septic tank) take on the pressure of the soil column and provide stability. BioPurite is suitable for areas with high GWL.
The overflow of wastewater from chamber to chamber occurs by gravity, there are no airlifts and there is nothing to clog.
The volume of the septic tank was reduced by the manufacturer. The model, which was previously offered for 5 people, is now offered for 8. This does not contribute to good cleaning.

What to consider:

Internal baffles may be poorly molded, leaks between the chambers will occur and the cleaning quality will deteriorate.
Branch pipes are cut through rubber cuffs. The rubber dries out and leaks over time.
The compressor compartment is located directly in the cover of the station, which is not very convenient for maintenance.
Poor quality components and assembly

Those who have to install sewers in clay and in high groundwater.
Those who select a septic tank for a public area (cafe, gas station, construction temporary hut). In such areas, insoluble debris is often dumped into the sewer, and BioPurite is not clogged due to gravity overflows.

Conclusions:

BioPurite is a good and inexpensive station. A minimum of electrics, a rigid body, no blockages - all this makes it popular. But a small volume, factory defects, cheap compressors and components, instability of cleaning are the annoying disadvantages of BioPurite. Because of them, we put it only on the 14th place in our TOP-list.

13. Station Crystal

Inexpensive biotreatment station from a Russian manufacturer. Made on the model of the Lithuanian septic tank Tridenis, but in comparison with it has important advantages.

Characteristics:

Manufacturer: Crystal
Type: biological treatment plant
Material: machine-wound fiberglass reinforced with carbon fiber
Degree of purification on a five-point scale: 3 points
Alarm: not provided, optional
Price: average
Maintenance: calling a vacuum truck for pumping out 1 time in 1.5-2 years
Warranty: 10 years for body and 1 year for electrical equipment

Why buy:

The crystal has a durable fiberglass body reinforced with carbon fiber.
The base of the body is conical, which contributes to a good fixation of the septic tank in the ground. It is also more convenient to pump out sediment from such a body.
The compressor is located under the cover and it is possible to install a pump for forced pumping. This distinguishes Crystal favorably from similar septic tanks, for example, from the Traidenis septic tank (in it the compressor is placed outside, and the installation of a pump for forced pumping is not provided).
Sprinkling is done with sand, not DSP, it is cheaper.

What to consider:

Like other stations without an averaging chamber (EvroBion, Ital Antey), Kristall needs a regular supply of wastewater, while their composition must be stable.
Maintenance of the Crystal - pumping out with a vacuum cleaner 1 time in 1.5-2 years. It is necessary to ensure the access of the sludge machine to the septic tank for 20-30 meters. The service is paid and takes time (you need to control the work and immediately after pumping out fill the septic tank with water so that it does not float).

For country houses with permanent residence and regular flow of wastewater into the septic tank.
For areas with problematic soils. The fiberglass hull is very rigid and strong, it is firmly held in the ground due to the conical shape.

Conclusions:

Relatively cheap station in a rigid case. It has an original cone design, which simplifies the pumping of sediment. Another plus is a very long warranty on the case. Disadvantages - the lack of an averaging chamber and a long exit to the mode. This station is not recommended for temporary residence. Therefore, we put the Crystal only in 13th place.

Polyethylene septic tank for simple settling of drains. It has been on the market for a long time, has a reputation as a reliable budget septic tank for good soils (sand, sandy loam, low groundwater).

Characteristics:

Manufacturer: Ecoprom
Type: septic tank
Material: low pressure polyethylene
Purification degree: 2 points
Price: below average.
Alarm: no, can be supplied according to customer's request
Maintenance: pumping out with a cesspool 1 time in 1.5 years.
Warranty: 1 year

Why is Rostock a good septic tank?

It has a cylindrical body with stiffeners, resistant to compression.
Inclined overflows and a two-section filtration system, retains impurities well.
In well-filtered soil, the manufacturer recommends sanding the septic tank. It is cheaper than sprinkling with a cement-sand mixture (CPS). The exception is the Rostock septic tank with an elongated neck: it is buried deeper and sprinkled with CPS due to the greater soil pressure.
Great guarantee. It should be borne in mind that some manufacturers of septic tanks do not provide a guarantee at all.
A special system of overflows, high cleaning rates for suspended solids.

What to consider:

The neck is welded to the body. At the moment, the manufacturing company is finalizing the septic tank, so that the neck is not welded, but solid.
The septic tank is anchored using a special set of curbstones. This kit is produced by the manufacturer of the septic tank.
The Rostock septic tank is relatively expensive in its segment (for example, it is more expensive than the Termit polyethylene septic tank with the same operating principle).
Wastewater from a septic tank smells. Further cleaning into the ground is needed, which limits the scope. But this is a disadvantage of all septic tanks.

If the soil on the site is sand or sandy loam, and the groundwater level is low.
If you need a relatively cheap, but at the same time reliable sewerage.

Conclusions:

If a septic tank is suitable for your site, then Rostock is the best option. However, after it, soil post-treatment is needed, which increases the cost of installation. Calling a sewer to pump out a septic tank costs money. The filtration field and the well, like the septic tank itself, need to be maintained (dig up and change the rubble). Deserved 12th place.

11. Station Ital Antey

Ital Antey is an economical septic tank from the Plast-Service company, which also produces Ital BIO septic tanks and other plastic structures.

Characteristics:

Manufacturer: Plast-Service
Type: biological treatment plant
Degree of purification on a five-point scale: 3 points
Price: below average
Alarm: no, optional
Maintenance: pumping out with a cesspool 1 time in 1.5-2 years, calling a service engineer every few months

Why buy:

The Antey septic tank has a cylindrical body and has lugs. Difficult soil is not an obstacle to the installation of this sewer.
The septic tank is light and compact, mounted without an excavator, which saves money and saves the site.
There is no risk of blockages, as the drain overflows by gravity.
Each model has both gravity and forced taps. This simplifies the selection, since it is not necessary to initially take into account the characteristics of the soil. The outlet is selected locally.

What to consider:

Only 2 models are produced, Antey 3 and Antey 5.
There is no receiving chamber for averaging drains, so the station can enter the mode for a long time. It is important that the flow of effluents be regular, and they do not contain aggressive chemicals.
The alarm is not provided by the manufacturer. Our company puts it in agreement with the customer, but this is paid as additional work.
To pump out the sludge, a sewer is called, and a service engineer is needed to service the station (washing, checking the electrics). Maintenance costs are on the rise.
The station has a collector with taps for setting aeration. In the absence of experience, setting up can be difficult.

It has an area with clay and high groundwater. Ital Antey is suitable for these conditions.
He lives outside the city all the time, so the mode of flow of effluents is more or less stable.
I am ready to periodically spend money on both a sewer and a service engineer.

Conclusions:

Ital Antey is an unpretentious biological treatment plant. It is recommended for those who do not fit the septic tank and who have limited budget. The degree of purification is low for the station. During service and commissioning, problems are possible. As a result - 11th place.

10. Stations EuroBion Art and Rusin

An interesting station from the NEP company, developed and patented by engineer Yuri Bobylev. The design turned out to be extremely successful, which provided this sewer with great demand.

Characteristics:

Manufacturer: NEP (National Ecological Project)
Type: biological treatment plant
Material: 8mm integrally foamed polypropylene
The degree of purification on a five-point scale: 4 points
Price: average
Alarm: lamp on cover and float in receiving chamber, not included
Maintenance: pumping out sludge with a service airlift every few months, calling a service engineer once every six months
Warranty: 3 years for the body and technological equipment (airlifts, aerators), 1 year for electrics

Why buy:

The body is made of expanded polypropylene and equipped with lugs. Suitable even for wetlands.
The station is reliable, equipped with one compressor and operates in one mode. The electrics won't let you down.
Due to the vertical layout of the chambers and gravity overflows, EuroBion does not clog.
EuroBion has a large volley discharge, thanks to the proprietary Aerodrain system. It doses the discharge of water from the station, which allows not only to increase the volume of salvo discharge, but also to reduce the removal of sludge.
It is possible to pump out silt without a cesspool, for this EuroBion has a regular airlift.

What to consider:

This station does not have a receiving chamber for averaging wastewater. In the first chamber, aeration and biological treatment immediately begin. Because of this, EuroBion takes a long time to enter the regime and for normal operation, effluents must be received at regular intervals.
When using this station, it is necessary to carefully monitor the composition of the waste water. Do not use detergents containing chlorine.

For those who have installed a bath in the house and need a septic tank with a large salvo discharge.
For a private house with year-round use.
For public areas where insoluble waste enters the septic tank. Blockages in this septic tank are not terrible.
For areas with high groundwater and/or clay.
For those who want to pump out a septic tank without a sewer. EuroBion has a service airlift for this.

Conclusions:

EuroBion in our rating is one line higher than Ital Antey. The Aerodrain system prevents the removal of sludge during salvo discharges. A wide range of models is offered, there are elongated modifications. There is also a budget modification Rusin. Service does not require a vacuum cleaner. At the same time, it is suitable only for permanent residence and is sensitive to the content of chemicals in wastewater.

9. Station Eurolos BIO

Robust station made of monolithic polypropylene. It uses a special type of aeration. The pump pumps water into the neck, where it is sprayed over the bio-load and saturated with oxygen. This solution makes the septic tank cheap and at the same time quite effective.

Characteristics:

Manufacturer: Eurolos
Type: biological treatment plant
Material: homogeneous polypropylene.
The degree of purification on a five-point scale: 4 points.
Price: average
Alarm: not provided, optional
Maintenance: calling a vacuum truck 1 time in 1.5-2 years
Warranty: 3 years body, 1 year electrical

Why buy:

The hull is cylindrical, the ground pressure is uniform over the entire area of the hull, squeezing by the ground is excluded.
There are lugs that take on the weight of the soil and make the septic tank stable.
The Eurolos BIO septic tank has a simple and reliable design. It does not have a compressor, only a timer-controlled pump from electrical equipment.
The septic tank is equipped with an ejector. He takes part of the flow passing through the pump and uses it for additional aeration. This improves the quality of cleaning.

What to consider:

The degree of purification is lower than in stations with compressor aeration. In Eurolos BIO, this problem is partially eliminated with the help of jet aeration (ejector).
It is important to choose the right septic tank for performance so that the system can cope with the volume of drains and there is no smell on the site.
Not very convenient electrical part. We advise you to equip the Eurolos BIO septic tank with a remote control unit, like Kolo Vesi.
The declared salvo discharge is small, but it is not overestimated.

If a site with high groundwater or clay.
If you want to install a sewer and forget about it. To pump out Eurolos BIO, a vacuum truck is called once a year, and no maintenance is required the rest of the time.
If insoluble debris, for example, the hair of dogs and cats, will definitely fall into the sewer.
If you need an inexpensive and reliable septic tank that will clean the drain to the state of technical water with the possibility of draining to the ground.

Conclusions:

Good and inexpensive station. It is arranged in the same way as Colo Vesi, but it costs 2 times cheaper, with the same declared productivity, it is 1.5 times more in volume and, in addition, it has ejector aeration. We recommend this station for installation, but we put it only in 9th place. The degree of purification is still lower than in stations with a receiving chamber for averaging wastewater and with compressor aeration.

8. Station Tver

The original Russian development has been produced for more than 20 years and receives many good reviews.

Characteristics:

Producer: TD Engineering equipment
Type: biological treatment plant
Material: homogeneous polypropylene
The price is high
Emergency signaling: not provided, installed additionally and connected in a remote electrical box
Maintenance: call a vacuum truck 1 time in 1.5-2 years.
Warranty: 1 year for body and hardware

Why buy:

The station has a large volume, can take a significant burst of discharge and copes well with wastewater treatment.
Body with semi-circular bottom, made of homogeneous 5 mm polypropylene, with lugs and stiffening ribs, adapted to ground pressure and suitable for high groundwater.
Tver is a single-mode station with one compressor, reliable and unpretentious.

What to consider:

The Tver station is expensive. It surpasses in price the most famous aeration stations Unilos Astra, Topas, BioDeca.
The thickness of the case is only 5 mm. The stiffeners do not fully compensate for this shortcoming.
Installation is difficult and expensive. The compressor is placed in the house or in the utility room and connected to the station by an air pipe. The pump is connected via a heat shrink sleeve. It is recommended to install a remote electrical box for disconnecting wires. Our company offers such a solution.
Alarm installation is not provided, we mount it additionally.
It is necessary to change limestone crushed stone and expanded clay. Crushed stone dissolves over time and you need to periodically fill up 1 bag. The silted expanded clay is first pumped out, and only then a new one is poured. Not every sewer undertakes such work.

Does not plan to service the septic tank frequently.
Wants to install a sewer and forget about it.
It can provide a 20-30 meter access to the septic tank for a sludge pump.
Has on site non-residential premises to install a compressor.
Knows that insoluble waste will fall into the sewer.

Conclusions:

The station is original in design and relatively expensive. We place it on the 8th place of our rating. The reasons are the compressor in the house, inconvenient electrical connection and thin plastic. These disadvantages do not allow Tver to rise higher, despite the high degree of purification.

7. Station Ital BIO

Biological treatment plant with large volume and rigid body. Great for difficult ground. Differs in a simple design and does not cause problems when using.

Characteristics:

Manufacturer: Plast-Service
Type: biological treatment plant
Material: uniform polypropylene 8 mm thick
The degree of purification on a five-point scale: 5 points
The price is high
Alarm: not provided, optional
Service: calling a vacuum truck every one and a half to two years, calling a service engineer once every six months
Warranty: 5 years for body and 1 year for hardware

Advantages of Ital BIO:

The special layout of the chambers makes it possible to maintain the temperature in the aeration tank that is optimal for cleaning.
There is an additional chamber for anaerobic cleaning, and, as a result, more volume and better quality cleaning, more volley discharge.
Body-cylinder with grousers. Suitable for clay heaving soils and for high groundwater.
All models have two outlets, gravity and forced. The method of drainage is selected locally, depending on the type of soil and the height of groundwater.
All overflows are self-flowing and do not clog.
Reliable device: single-mode station, with 1 compressor.

What is important to consider:

The nozzles are made in production, so it is important to accurately determine the depth of the pipe supply during the measurement.
An alarm is not provided and is optional, for an additional fee.
Ital BIO is more expensive than the top septic tanks BioDeca, Topas, Unilos Astra.
For pumping out, it is necessary to call a vacuum truck, respectively, there must be an entrance of a vacuum truck to the station for 30 meters.
For flushing airlifts, checking equipment and aeration settings, it is better to call a Zagorod service engineer. These are additional expenses.

For any soil and any level of groundwater.
For those who are willing to pay for pumping out with a cesspool machine and for after-sales service.

Conclusions:

The station is durable, has a large volume and volley discharge. There are two branches at once, gravity and forced. These are all pluses. But the station is expensive to maintain - you need to call both a sewer and a service engineer from our company. Sewerage Ital BIO is quite expensive, but it is not provided for, for example, alarm. We install it additionally, while the system itself, the lamp and the float, are offered free of charge in our company as a bonus to the purchase.

6. Unilos Astra Station

It is a station with a polypropylene body, suitable for any type of soil and water table. SBM-Group is a major manufacturer of wastewater treatment plants. The production is located in the Yaroslavl region, in the city of Uglich, and there are warehouses in Moscow, St. Petersburg and Yekaterinburg (in the same cities where the branches of the Zagorod company are located, we ship septic tanks directly from the manufacturers' warehouses).

Characteristics:

Manufacturer: SBM-group
Type: biological treatment plant
Material: 15mm integrally foamed polypropylene
The degree of purification on a five-point scale: 5 points
Price: average
Alarm: LED lamp on the lid and the float in the first chamber, not included, a gift from our company

Why buy:

The body is made of expanded polypropylene, it is durable and with good thermal insulation.
There is a receiving chamber for averaging drains.
No need to call a vacuum cleaner for service. For self-pumping 1 time in 3 months there is a service airlift. For full service, a service engineer is called in, who is easier to communicate with than a vacuum truck.

What to consider:

The building, like that of the Topas station, is rectangular. Accordingly, the risk of deformation is higher, although if the station is not left empty after pumping, it will not suffer.
The body is welded by hand (extruder) from 4 sheets of polypropylene. The soil presses unevenly and tension arises on the ribs.
There are no lugs, although, as in the case of Topas, this is not critical. The filled station is stable in the ground.
The operating modes are switched through a solenoid valve. It is sensitive to power surges, therefore, when installing the station, a stabilizer is installed in the house. This increases the cost of installation, but without it, the manufacturer does not give a guarantee for electrical equipment.
The drain is pumped by airlifts, and blockages for Astra are a frequent occurrence.
There are maintenance issues. The nozzles on the distributor are metal, and in order to remove the hoses, they must first be heated with a hot air gun. In general, you can do the maintenance yourself, but this requires skills and expensive equipment (building hair dryer, Karcher).

For all ground conditions and for any type of residence.
For situations in which it is impossible or undesirable to be serviced by a vacuum truck (there is no access for a vacuum truck, you don’t want to spend time and money on this).
For those who are ready to pay for a voltage stabilizer (about 10 thousand rubles), so as not to have problems with the electrician in the future.

Conclusions:

Astra is a workhorse. If it is installed and used correctly, it works very well, cleans the drain well and does not break. But the electrician is still not very unreliable, you need a voltage stabilizer, and this is another 2,500 to 10,000 rubles to the price. There are no lugs on the body, and the airlifts periodically become clogged. All this throws Astra to 5th place in the ranking.

5. Station Topas-S

It differs from the standard Topas in that it has one compressor with a solenoid valve, and not two compressors working alternately. The electrical circuit is the same as in the Unilos Astra and Volgar stations. But in some respects Topas-S is better.

Characteristics:

Manufacturer: Topol-Eco
Type: biological treatment plant
Material: integrally foamed polypropylene
The degree of purification on a five-point scale: 5 points
The price is high
Alarm: lamp and float switch, not included
Maintenance: independent pumping of sludge 1 time in 3-4 months, call a service engineer 1 time in six months
Warranty: 5 years for body, 2 years for hardware, and 1 year for solenoid valve.

Why buy Topas-S:

Housing made of foamed polypropylene with high thermal insulation. Such a body will not squeeze during frosty heaving of the soil, the water in the septic tank will not freeze in winter.
The case, like that of the standard Topas, is made using a special technology, from two sheets bent and welded to the full thickness. There are no seams on the ribs and therefore higher strength.
Purified water can be drained to open ground, without soil post-treatment. The degree of purification in Topas-S reaches 98%.
Suitable for installation in any soil. There are no lugs on the body, but the station is quite heavy and does not float up unless left empty.
It is serviced independently or by a service engineer of the Zagorod company. You don't need to call an attendant.

Things to consider:

A box-shaped body is more susceptible to crushing than a cylindrical body, although field experience indicates that the risk is minimal.
A voltage stabilizer is not required and is not a condition of the warranty, but its installation is recommended.
The phases are switched using a float switch. Hair and other insoluble debris can wrap around it, and the operation of the station will be disrupted. It is important to maintain the septic tank and remove the garbage on time (at least once every 6 months).
The septic tank has big weight. For installation of models for 8-10 users and more, an excavator and a manipulator are rented, installation costs increase. At the same time, an entrance for special equipment is needed, the landscape of the site may suffer.

For any soil clay soil, quicksand, high GWL).
If DIY service or with the help of a service engineer is preferable.

Conclusions:

Topas-S has one compressor and two modes of operation, as in Astra. But for Topas-S, a voltage stabilizer is not a guarantee condition. It turns out that with the same characteristics, Topas-S is more reliable than Astra. To this we must add an improved technology for manufacturing the case. We take all this into account and put the Topas-S station in 5th place.

4. Volgar station

The biological treatment plant Volgar was designed on the basis of the stations Topas, BioDeca, Unilos Astra. The station is relatively new, but is already actively sold and receives feedback from the owners. When creating the Volgar, the best was taken from other aeration septic tanks, but it also has its own advantages.

Characteristics:

Manufacturer: Volgar76
Type: biological treatment plant
Material: homogeneous polypropylene
The degree of purification on a five-point scale: 5 points
Price: average
Alarms: flashing strobe lights and float sensor included
Maintenance: independent pumping of sludge 1 time in 3-4 months, call a service engineer 1 time in six months
Warranty: 3 years for chassis, 1 year for hardware (electrical only if voltage stabilizer is installed)

Advantages of the Volgar station:

The cylindrical body is not afraid of being crushed by the ground.
The station is relatively light and is mounted manually, saving money, special equipment does not spoil the landscape of the site.
Grousers are made on the body, so the station can be installed in high groundwater.
Emergency signaling with pulse strobe lamps. It is important that the alarm is already included.
The instrument compartment is easily unscrewed for easy maintenance.

Things to keep in mind:

Volgar is a station with 2 modes of operation and 1 compressor. The phases are switched through a solenoid valve, which is sensitive to voltage drops. It is imperative to install a voltage stabilizer, as for the Unilos Astra station.

If the site is clay, high groundwater or quicksand.
If there is a desire to save on installation and not overpay for the rental of special equipment and for sand (it requires more when installing with an excavator).
If the customer does not want to deal with the sewers and prefers to pump out the septic tank himself or with the help of a service engineer. Also in cases where it is impossible to ensure the access of the sewer truck to the septic tank at the required distance (20-30 meters).
Also, if you want to install the station manually, without special equipment.

Conclusions:

Volgar, like Topas and Astra, is a two-mode station, but it has a cylindrical body and has lugs. In addition, an alarm is supplied with the station. These are xenon strobe lamps with a pulsed signal (up to 60 flashes per minute). Such a signal is visible even in winter through the snow. Due to these advantages, Volgar takes the 4th place.

And now the top three!

He was one of the first on the Russian market and still remains the best-selling. Topas septic tank is produced by Topol-Eco. The company has a large production capacity and annually produces more than 20,000 pieces of equipment. The advantage of Topol-Eco is that it makes polypropylene sheets for its septic tanks. Other manufacturers usually purchase material and cannot control the quality of its manufacture.

Characteristics:

Manufacturer: Topol-Eco
Type: biological treatment plant
Material: 15mm integrally foamed polypropylene
The degree of purification on a five-point scale: 5 points
The price is high
Alarm: a lamp on the lid and a float in the receiving chamber, purchased separately and installed during installation (from the company Zagorod alarm as a gift).
Maintenance: independent pumping of sludge 1 time in 3-4 months, call a service engineer 1 time in six months
Warranty: 5 years for body technological equipment(aeration elements, airlifts) and electrics (compressors, pump in forced models)

Why buy:

The body is made of integrally foamed, three-layer polypropylene. The intermediate layer is porous and holds heat well.
In the manufacture of the case, 2 sheets of polypropylene are used, which are bent and welded on the machine to the full thickness. This is more reliable than manually welding the case from several polypropylene sheets.
The effluent is treated to 98% BOD5 (indicator of organic content at the outlet of the station) and is discharged to the ground without additional treatment.

What to consider:

The body has the shape of a parallelepiped, so the pressure of the soil on it is distributed unevenly. Higher probability of deformation under strong pressure from the outside (soil) or from the inside (water).
Topas has no lugs, which, theoretically, reduces its stability. In fact, a filled septic tank is quite heavy and, if used correctly, it is stable in the ground.
Topas is a heavy septic tank. Models 8 and above are already mounted with an excavator and a manipulator.

For cottages and country houses, regardless of the type of soil and the level of groundwater on the site.
For any mode of residence - all year round, seasonally or on short trips.

Conclusions:

Topas is a time-tested biotreatment station, with a reliable design, with a chamber for averaging wastewater. We definitely recommend this station. The disadvantages include 2 operating modes, lack of lugs, relatively high cost. These are not critical shortcomings, but such stations as BioDeca and Genesis do not have them. Therefore, Topas has only 3rd place.

2. Station BioDeca

One of the most popular and certainly one of the most reliable bioremediation stations. The manufacturer tried to make the station as simple as possible, but at the same time durable and efficient. Wastewater is 98% purified and discharged directly into the ditch.

Characteristics:

Manufacturer: Deca
Type: biological treatment plant
Material: Integral expanded polypropylene from 8 mm thick (3 and 5 person models) to 10 mm thick (8 person models and above)
The degree of purification on a five-point scale: 5 points
Price: average
Alarm: lamp and float switch already included.
Maintenance: independent pumping of sludge 1 time in 3-4 months, call a service engineer 1 time in 6 months
Warranty: 5 years for the body and all equipment (subject to timely maintenance)

BioDeca Benefits:

Cylinder-shaped body, resistant to heavy loads.
There are lugs on the body for greater stability. They make the station suitable for installation in high groundwater.
The filter of rough fractions with openings from above and with blowing from below upwards, the station is well protected from blockages.
One compressor and one mode of operation: a simple and reliable solution, no voltage stabilizer is needed.
The station comes with a special kit that allows you to quickly convert the station from gravity to forced. This is very convenient if the conditions on the site have changed (groundwater has increased, the neighbors have filled up the ditch and made gravity drainage impossible).
The company gives an extended 5-year warranty for the body, electrics and process equipment when serviced by an authorized dealer (Zagorod company).

What to consider:

· Due to the cylindrical body, the volume of the BioDeca is less than that of stations with a rectangular body (for example, than the station Unilos Astra). This is not critical, but with a large estimated volume of effluents, this nuance should be borne in mind.
BioDeck has one mode of operation, the compressor distributes air to all airlifts, which means that it is more powerful (consumes more electricity) and noisier than the compressor, for example, in Astra, in which air is supplied in two modes and the compressor performance may be less . This is important if you save electricity and, moreover, do not want to hear how the sewer works all the time.

For flooded and/or clayey soils.
For any type of accommodation (permanently, seasonally or short-term).
If there is no certainty that the conditions on the site will not change and the branch will not have to be redone.

Conclusions:

BioDeca and Topas are the most famous and sought-after septic tanks. But do we put BioDeca on the line above Topas? Why? Firstly, the BioDeca has a more successful body design, it is cylindrical and with lugs. Secondly, BioDeck has one mode, which increases reliability. And, thirdly, BioDeca, with all the advantages, is simply cheaper.

1. Station Genesis

Genesis is the most modern aeration station. It incorporates the best of other bioremediation plants and at the same time has features that its competitors do not have.

Characteristics:

Manufacturer: Deca
Type: biological treatment plant
Material: 10mm integrally foamed polypropylene
The degree of purification on a five-point scale: 5 points
Price: very high
Alarm: GSM module with SIM card included.
Service: pumping out sludge with a service airlift or calling a service engineer once every 8 months
Warranty: 5 years for body and all hardware, same as BioDeca

At Genesis Station:

The body is reinforced with ring bandages. Wall thickness - 10 mm. This is more than other stations made of polypropylene. That is, the Genesis septic tank has the most durable case.
Grousers provided. They prevent groundwater from pushing the station out.
There is an additional expansion chamber that accepts excess waste volume. Due to this, Genesis has the largest salvo discharge.
The coarse fraction filter has a special design. It is completely protected from debris.
There is a narrow sloping overflow between the aeration tank and the secondary clarifier. This is an additional protection against clogging.
An alarm system with a GSM module is installed. A SIM card is inserted into the module and when the station is flooded or power is cut off, the owner receives an SMS notification.
The longest warranty on the market is 5 years for the body and all hardware.

What to consider:

The Genesis septic tank is one of the most expensive on the market, although its high level of cleaning and reliability completely pays off its cost.
The station is not 100% protected from blockages, despite the special filter of coarse fractions.
Genesis has a powerful compressor that makes noise. But at a distance of 2-3 meters is no longer felt.

Those who have high groundwater, quicksand or clay in their suburban area.
Those who live on the site seasonally or on short trips and cannot constantly monitor the sewerage. The station itself notifies the owner about the problem.

conclusions

A long warranty, the most durable case, one mode of operation, protection of the main airlift from clogging - these are the real advantages of the Genesis station. In addition, it also has an alarm with a GSM module, which allows you to control the station remotely. The only negative is the high cost, but with such advantages, it is fully justified. Remember the station Kolo Vesi. It costs the same as the Genesis, but is on the other end of the rankings.

User Choice 4 The best aerator 5

One of the most important issues when buying a plot, cottage or country house is the availability of communications. And if, as a rule, there are no problems with water or electricity, then central sewerage in the private sector, especially far from the city, is a rarity. And the fastest and most practical solution to this problem is to buy a septic tank.

The two most common types of individual treatment facilities are a non-volatile (autonomous) septic tank and a volatile station. Both types of waste disposal devices use several stages of treatment: mechanical sedimentation of suspended matter, filtration and biological treatment. Self-contained septic tanks use anaerobic bacteria to process waste, which do not need oxygen, but act slowly. In energy-dependent devices, biological filtration occurs with the help of more active aerobic microorganisms that require the use of aerators. But the level of purification in such septic tanks reaches 98%.

The choice of the optimal model of the cleaning device depends on several factors:

Required performance. For one person, the volume of wastewater is usually laid equal to 150 - 200 liters per day.
Availability of electricity on site.
Plot size. Autonomous septic tanks require a larger area, as they are equipped with additional ground filtration fields.
Ground water level. High GWL may require the use of additional engineering solutions.
Soil composition. For areas with hard rocks, it is better to use horizontal septic tanks, since they require a shallower pit.

Our review contains models of septic tanks with the best technical and operational characteristics. When compiling the rating, the following were taken into account:

recommendations of civil engineers;
feedback from users who have installed specific models of cleaning devices in their area;
value for money septic tanks.

The best budget septic tanks for summer cottages

Septic tanks for installation on suburban area are small and relatively cheap. As a rule, these are simple stand-alone models that act as a sump and are connected to an additional filtration system. They have an extremely simple one-piece design, a low level of productivity, and are also unpretentious in maintenance.

4 TANK-1

Excellent price/performance ratio
Country Russia
Average price: 19,500 rubles.
Rating (2019): 4.6

Tank-1 is the youngest model in the line of non-volatile septic tanks Triton Plastic. Its design is simplified to the limit: there are only two chambers: coarse primary treatment and secondary biological treatment. But, nevertheless, this small septic tank, capable of treating up to 600 liters of wastewater per day, has all the advantages inherent in the more expensive models of the company: it has a horizontal layout and a durable one-piece body with special stiffeners, which increases the service life and eliminates the penetration of soil water into the interior of the structure.

This compact model is ideal for installation in the country and is designed for use by two or three people. The level of wastewater treatment for this septic tank is 75 - 80%, therefore, it is recommended to use a special infiltrator in which additional treatment takes place with it. Buyers note the compact dimensions of the septic tank, easy installation and trouble-free operation. However, you still have to clean the chambers from sediment once every few years.

3 Termite Profi 1.2

The strongest container
Country Russia
Average price: 23,500 rubles.
Rating (2019): 4.6

This miniature vertical septic tank can serve no more than two people. The degree of wastewater treatment reaches 85%. Due to its small weight - only 80 kg, Termit Profi 1.2 is easily transported and mounted. This is a great option for a small country house or separately. standing bath. An additional advantage is that the wall thickness of the Termit Profi 1.2 tank reaches 20 mm, and the shape of the body is specially designed for optimal performance under load.

According to user reviews, this septic tank is easy to install and maintain. Experienced summer residents recommend that it is imperative to sprinkle the container with sand cement to increase the service life of the structure. Among the disadvantages is the impossibility of using this septic tank with a high level of groundwater on the site.

2 MICROB 450

Best price
Country Russia
Average price: 12,400 rubles.
Rating (2019): 4.8

For a dacha that is visited by 1-2 people, a guest house or a change house for the period of building a house, the best option would be a budget septic tank Microb 450. Its capacity is 150 liters per day, and its weight is only 35 kg. Of course, to install it, you will need to make a sand cushion, and apply a layer of insulation on top, since its wall thickness is small. But this septic tank can be installed in areas with any level of groundwater - of course, with the implementation of the manufacturer's design recommendations.

Customers especially like the device's reasonable price and easy installation. Of course, for a country house you will need a septic tank with a larger capacity, but for periodic trips to the country and with a limited budget, Microb 450 is ideal.

1 Rostok Mini

Stable performance in all conditions
Country Russia
Average price: 24,120 rubles.
Rating (2019): 4.9

Inexpensive autonomous septic tank for a small country house. According to user reviews, due to the small volume (1000 liters) and the lightness of the design (total weight is 65 kilograms), installation does not cause much difficulty. The filtration capacity is 200 liters per day - this is not much, but the septic tank is designed for one or two users. The Rostok Mini copes well with the assigned functions, it requires pumping out once or twice a year (provided that all the supplies and the system are in good order). Very a good option for the equipment of a dacha or a house, which will not hit the pockets of potential consumers hard.

Advantages:

seamless durable and lightweight (65 kilograms) plastic case;
the presence of additional stiffeners to give structural strength;
completely blocks unpleasant odors;
low, but stable performance;
does not require frequent maintenance;
attractive price.

Flaws:

for its price category - no.

The best volatile septic tanks

Treatment stations, whose biological filters are populated with aerobic microorganisms, are the most technically advanced version of septic tanks. They produce 98% purified water at the outlet - it can be used for irrigation, other technical needs, or discharged directly into the ground. Cleaning the tanks from silt is needed every couple of years, and the organic sediment itself is an excellent fertilizer for plants on the site. Since the drains do not need additional ground filtration, the structure takes up a minimum of space.

The main disadvantage of such systems is the need for electricity. As part of the aerobic system, there is always an aerator-compressor that saturates the liquid with oxygen necessary for the vital activity of bacteria. It is this fact that explains the higher cost of volatile stations - both during purchase and installation, and during operation.

5 ERGOBOX 4

Optimal price-quality ratio
Country Russia
Average price: 60,900 rubles.
Rating (2019): 4.7

The body of this treatment plant is manufactured using rotational molding technology, which guarantees the absence of seams and uniform thickness of the material. As part of the septic tank, Japanese compressors and German pumps are used in order to ensure the smooth operation of the entire system. In case of loss of power supply, the station can operate normally for two days, after which it switches to the mode of an autonomous septic tank with an anaerobic filter.

Users note, first of all, the excellent value for money of this model. With a capacity of 800 liters, it consumes only 1.5 kW per day and provides a volume of water disposal sufficient for the permanent residence of 4 people. You can choose either a gravity-fed installation or a forced discharge option for areas with a high groundwater level.

4 Tver-0.5P

The best aerator
Country Russia
Average price: 75,000 rubles.
Rating (2019): 4.7

The service life of this septic tank declared by the manufacturer is 50 years. This becomes possible due to the fact that special structural plastic is used to cast the body, and compressor equipment - Japanese made. The degree of water purification in this line of treatment facilities reaches 98%, which eliminates the need for additional soil filters.

The maximum productivity of the equipment is 500 liters per day, so Tver-0.5P can be recommended for a dacha or a country house with permanent residence of 2-3 people. Customer reviews are almost the same: the device does its job perfectly, there are no smells and noise, and periodic maintenance is required only once a year. The only drawback is the high price with relatively low performance.

3 Unilos Astra 5

User Choice
Country Russia
Average price: 76,000 rubles.
Rating (2019): 4.8

One of the most famous septic tank models on the domestic market, which does not have a single visible weak point. If you do not take into account the price level, then the fifth Astra fully meets the requirements of a premium class product (if this is acceptable in this case). The system is based on a very fine filtering effect on the incoming wastewater - thanks to aerobic and anaerobic filters, it is possible to achieve almost 100% of the purification rate. Thus, up to one cubic meter of wastewater is processed per day, which is a normal average value. The input of the drain pipe can be organized at heights from 0.6 to 1.2 meters relative to the ground level, which greatly simplifies the installation of the tank.

Advantages:

high degree of aerobic and anaerobic purification (98%);
reliable container body;
good throughput (filtering up to one cubic meter runoff water per day).

2 Eco-Grand 15 (Poplar)

Best processing ability
Country Russia
Average price: 148,230 rubles.
Rating (2019): 4.8

An overall volatile septic tank, ideal for equipping large country houses. Except that the tank weighs 380 kilograms, there are no problems with installation. And in terms of performance, everything is very good: the entire volume of the septic tank is divided into four compartments, two of which are equipped with aerators. After the effluents enter the receiving chamber (volley ejection can reach 450 liters), due to aeration, the solid fractions begin to decompose.

In a separate compartment under the controls there is a compressor for pumping wastewater through the system. By the way, the latter consumes a total of up to 2.8 kilowatts of energy per day - a little, but a decent amount accumulates over a long time of work.

Advantages:

active filtration and aeration of incoming wastewater;
good performance (1.8-2.0 cubic meters of wastewater per day);
capacity equal to six cubic meters.

Flaws:

high price;
increased power consumption.

1 TOPAS 8

The most economical model
Country Russia
Average price: 99,875 rubles.
Rating (2019): 4.9

One of the most economical energy-dependent septic tanks available to a wide range of consumers. Putting such a tank in the country is not entirely justified - it is much better suited to a small country house. The convenience of manual installation (as in stand-alone models) is no longer provided here - the entire structure weighs nearly 350 kilograms. Thanks to the installed filters, it does not require cleaning, it well limits unpleasant odors, and also filters up to 1.5 cubic meters of wastewater per day. According to users, the cost of power supply is noticeable, but much less than that of competitors and older models of this series - the septic tank consumes only 1.5 kilowatts per day.

Advantages:

popularity among users;
low power consumption;
high efficiency filtration;
reliable case;
ease of operation and low maintenance requirements.

Flaws:

not detected.

The best autonomous septic tanks

Autonomous septic tanks that do not require connection to the electrical network - best option for a summer cottage or a country house in a remote area where there are problems with electricity. Their design does not contain moving mechanical parts, so they are simple, reliable and will perform their functions in any case.

Of course, there are also disadvantages - lower productivity, worse level of effluent clarification. Top Models provide no more than 85% purification, and, therefore, the water needs additional filtration. There are several ways - drainage fields, infiltrators, seepage wells - and they all mean additional money spendings and reduce usable area. However, for houses with periodic residence, such structures may be more preferable, since they do not consume electricity and can be easily mothballed if necessary.

3 Uponor Sako

Good quality plastic
A country: Sweden/Finland (made in Russia)
Average price: RUB 67,575
Rating (2019): 4.7

The Scandinavian concern for the production of serious household equipment has quite successfully entered the Russian market. The domestic branch has launched the production of autonomous Uponor Sako septic tanks, suitable for installation both in a private house and in a summer cottage. In general, the system is not bad: it reliably retains unpleasant odors, filters wastewater without problems (but not perfect), and also does not impose high maintenance requirements. The problem area, judging by user reviews, is the extreme intolerance to the removal of rain and drainage water to the local cleaning system. Why this is so is a matter of intense debate. But the fact that this is an obvious minus is supported by all and unanimously.

Advantages:

good standard filtration efficiency;
quality body materials.

Flaws:

rainwater or drainage water entering the treatment system leads to a deterioration in filtering capacity.

2 Termite Profi 3.0

Maximum degree of cleaning in the class
Country Russia
Average price: 49,100 rubles.
Rating (2019): 4.7

The performance of this model, which uses the principle of anaerobic clarification of wastewater, is 1200 liters per day. At the same time, the level of purification reaches 85%, which allows minimizing the area of the final soil filtration. Such a septic tank with a sufficient supply provides permanent residence for six people. The tank is flushed only once a year, while the structure is completely autonomous.

According to user reviews, the septic tank fully complies with the characteristics declared by the manufacturers, is reliable and practical. It is especially convenient to use it for seasonal living: mothballing it for the winter and then putting it back into operation is not a problem. The disadvantages include a rather complicated installation procedure.

1 Triton-ED-3500 Horizontal

Profitable price
Country Russia
Average price: 43,500 rubles.
Rating (2019): 4.8

This is a relatively inexpensive option for a cleaning system for a summer house or a country house, where there are significant problems with the power supply. Productivity of model - 700 liters a day that provides requirements of 4 - 6 people. At the same time, the septic tank does not require an electrical connection, and the sludge can be pumped out once a year. Of course, in order for the water discharged into the ground to be sufficiently purified, it will be necessary to additionally apply a drainage field or an infiltrator.

Buyers especially like the horizontal layout of the septic tank, which allows you to limit the depth of the pit, as well as its independence from the mains. The disadvantages of the device are that it must be placed away from living quarters, since it is not possible to completely get rid of odors. This treatment plant is especially well suited for a country house in which a family of 2-3 people lives, but guests periodically come.
