Which septic tank is better - features of choosing a septic tank for home and garden. Modern septic tanks for summer cottages: which is better, market overview, professional recommendations, owner reviews Modern septic tank for a country house

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 of installation and maintenance of septic tanks and stations in different regions of Russia (Northwestern Federal District, Central Federal District, 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 refers 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 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
• Service: 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 semicircular 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.
• It has a non-residential premises on the site for the installation of 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 of cleaning, more volley discharge.
• Body-cylinder with grousers. Suitable for clayey 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 taps 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 does not provide, for example, an 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 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 is heavy. 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 groundwater level).
• 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 dual-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 the body, for technological equipment (aeration elements, airlifts) and for 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, when 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 operating mode, 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.

Septic tanks are of two types. A "regular" septic tank is a simple storage device, which works primarily as a sump. Plus - absolute simplicity, but the degree of purification is low. Therefore, the discharged effluents must either be filtered additionally, or regularly call the sewers with their tank, and each call is money.

Therefore, more complex septic tanks are much more profitable in the long run ( autonomous sewage systems), giving the output of activated sludge and water with a sufficiently high degree of purification - almost one hundred percent. In such septic tanks, aerobic bacteria usually do their job, which is helped by an aerator that forcibly blows air through the tank. Something like in an aquarium, only the "fish" there are microscopic and eat completely tasteless. The same aeration units, only much more powerful, are also used at Vodokanals as the main stage in the operation of sewage treatment plants. At the same time, anaerobic bacteria “work” in septic tanks, which do not even need to be populated - they get there straight from you. Therefore, a large primary clarifier is not only useful for mechanical cleaning.

But you can do without aeration, at the same time getting rid of the compressor: it’s cheaper and more reliable, at first glance. Can be used biofilter- this is either a mesh or a cassette with porous granules. Here, at the same time, sludge is sifted out and bacteria “live”. One pass of the drain through the filter is not particularly effective, so recirculation is used with a special pump. Even if you accidentally pour something vigorously chemical into the sewer and arrange a total Holocaust for microscopic coprofiles, at least mechanical cleaning will be preserved. A septic tank on a biofilter can be made quite compact. The disadvantage is obvious - the filter inevitably becomes dirty and requires maintenance, while it is enough to pump out sludge from the aerator from time to time. Without additional air saturation in the biofilter, only anaerobic bacteria can “work” normally.

The most efficient, of course, septic tanks, where cleaning goes through biofilters, and aeration of accumulated effluents occurs. But such a septic tank will simultaneously combine the disadvantages of both systems.

As for performance, the first thing to consider is waste volume- It is generally accepted that one person per day drains up to 200 liters of water into the sewer. That is, in theory, a family of 4 people needs a septic tank that “digests” up to 0.8 cubic meters per day. But in practice, of course, smaller models, up to 600 liters, also work great. Do not forget to take into account such a parameter as maximum salvo discharge volume- this is the volume of liquid that can be "assimilated" by the septic tank without disrupting performance in one "sip".

The septic tank has long gained popularity among owners of country houses. This is a much more practical and safe treatment facility than a cesspool, which many summer residents are so accustomed to. 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 sewer pipes are laid from the house and connected 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 option for sewerage in a 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.

Today they produce various types of 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 availability, easy installation and low cost. 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 elevated groundwater levels.

Septic tanks with deep cleaning purify and disinfect water by 90-100%, therefore, wastewater is disposed of into the ground without the risk of environmental pollution. 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 a suitable option for a country cottage in which 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 central 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 accumulative 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. So, for a 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 the best septic tanks for a country house: a rating based on customer and expert reviews.

Top 10 septic tanks for summer cottages

Experts call the Tank the best autonomous septic tank. Among devices that depend on electricity, Topol collected the most positive feedback. 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 at the first stages of creating a wooden house project, we carry out the necessary calculations for the installation of each engineering system, including water supply and sewerage, ventilation and electrical wiring, and heating. As a result, you get a reliable system that will work for many years without problems!

It is not so easy to purchase a suitable septic tank for a country house - what to choose depends on many factors, so it is important to determine the main priorities and criteria for evaluating the compared models. Of course, the advice of professionals and the help of neighbors can be of great help, but it should be remembered that the choice in each case is individual. It depends, first of all, on the needs of the residents of the house and the conditions at a particular facility. The right choice will ensure maximum comfort and avoid problems during the operation and maintenance of an autonomous sewer system.

When figuring out which septic tank to choose for a country house, it should be understood that it is important not only to compare models with each other, but also to correlate their characteristics with specific conditions.

Take into account the following features:

• climatic conditions,
• structure, density and other features of the soil on the site,
• mode of operation, which is determined by the nature of residence in the house (permanent, seasonal, periodic),
• average daily volume of wastewater (this parameter can be calculated according to a more complex scheme, taking into account the type and number of plumbing fixtures and washing equipment, but more often they use a simplified scheme, considering that the average daily water consumption of one person is about 200 liters).

Models of utilizers and their features

Any septic tank for the sewerage of a country house has its own characteristics.

Drives

Accumulators are the cheapest and simplest utilizers at the construction stage. It is advisable to choose them in the case when the house is not used too often or if the owners are ready to use the services of vacuum cleaners often.

Factory septic tanks with additional stages of post-treatment

Factory non-volatile septic tanks for a country house (for example, Tank, Triton, etc.) are equipped with infiltrators for efficient operation, or soil purification systems for them can be arranged independently. In the tanks of such products, sedimentation and partial purification of wastewater take place, and the final biological decomposition of impurities with the help of bacteria is carried out in the soil. Many people know that to install such septic tanks areas with high groundwater are not suitable, however, there is one more nuance - the filtration fields cannot always be in one place, and their transfer is a rather laborious matter, associated with a large amount of excavation work. The choice of a septic tank for a country house should take into account all the features of operation.

Tip: Instead of filtration fields, it is possible to use a drainage well with a filtering bottom.

Self-made septic tanks

Self-construction of a septic tank takes time and effort, but this is largely justified by the cost-effectiveness of the option. Building a septic tank is much cheaper than buying a factory model.

Sequentially connected settling tanks, poured concrete or, as well as other materials, provide stepwise clarification of drains and can be quite effective with the right choice of volume and type of construction, as well as subject to the recommendations of specialists during the construction phase.

Deep Cleaning Stations

Local deep cleaning stations for wastewater can only be purchased. Settling of impurities in such models is combined with the decomposition of organic inclusions under the influence of and anaerobic and aerobic bacteria. The advantages of such facilities are a high degree of purification and minimal maintenance requirements - VOCs operate in automatic mode. However, it should be remembered that deep cleaning stations volatile and need to be connected to the mains supply. In addition, for many vacation home owners, the high cost of VOCs is a deterrent to buying.

Soil features

Before determining which septic tank is best for a country house, study in detail the geological conditions on your site. In addition to the type of soil, the level of occurrence of surface waters, as well as the height of their rise, for example, during a flood, is important.

Models for light soils

If the soil in the country house or the backyard of a country house is sandy or with a high content of sand (sandy loam), any type of septic tank can be chosen for arranging an autonomous sewage system. In particular, models with soil purification systems are effective under these conditions, since light soils pass and filter water well.

On light soils, both expensive bio-treatment stations and simple budget drives work well.

Models for heavy soils

The high content of clay, which allows water to pass through only in a dry state, and, being saturated with moisture, becomes a waterproofing agent, imposes certain restrictions when choosing a treatment plant. If the soil on the site is clayey or loamy, and you are looking for the best septic tank for a country house, the rating will be topped by hermetic storage tanks and local treatment stations (VOCs). In this case, it is irrational to install a model with soil post-treatment. Theoretically, this is possible, but for the normal functioning of the device, a huge amount of earthwork will have to be done - to remove clay soil, replacing it with rubble or sand.

Models for sites with high groundwater levels

A high level of groundwater or a significant rise in a flood can create certain problems in the operation of an autonomous sewer. To avoid them, it is important to choose the right type of utilizer. Models that provide for the filtration of wastewater through the soil will not work in this case - the impurities present in them will enter the groundwater.

Acceptable options are:

• sealed storage,
• VOCs, which provide for the forced removal of the purified liquid,
• septic tanks with a post-treatment system located on the surface of the soil.

Obviously, under any conditions, you can find the optimally suitable septic tank for a country house - decide for yourself what to choose.

Performance of treatment facilities

For trouble-free operation of the septic tank and prevention of overcrowding of tanks, it is important to choose the right model performance. This parameter, in turn, is related to the volume of cameras and their number.

It has already been indicated above that the average daily volume of fluid intake is about 200 liters per person. The septic tank, according to accepted norms and rules, must contain the amount of drains for three days, so this figure should be tripled and multiplied by the number of residents. The result obtained will be the required performance of the utilizer, but experts do not recommend choosing “at a minimum”, you should make a small margin - 10-15% of the calculated volume, which is a kind of insurance and a way to reduce the risk of overfilling tanks.

Having decided on the volume of the product, you can solve the issue of the number of cameras.

• Single-chamber models are suitable for a minimum amount of wastewater (average daily volume is less than a cubic meter).
• If the daily volume of effluents is no more than ten cubic meters, a two-chamber septic tank will be the best option.
• Three-chamber models will ensure trouble-free waste disposal, even if a family of 4 lives permanently in the house, they are designed to process wastewater in a volume of more than 10 cubic meters per day.

Pricing

Many manufacturers produce various types of septic tanks for a country house. The presence in the model lines of products with different parameters allows for each home to make a rational choice. At the same time, there are features characteristic of each brand.

All parameters affect the cost of the utilizer, including:

• septic volume,
• the number of tanks connected in series (chambers, cleaning stages),
• wastewater treatment technology,
• availability of additional equipment (float level gauges, automatic control systems, filters, drainage pumps, airlifts, compressors),
• case material,
• manufacturing firm.

You can learn from another article as a system of soil post-treatment.

Popular Models

In order to make it easier to navigate in the variety of models, we offer a brief overview of septic tanks for a country house of the most famous manufacturers.

Tank

Non-volatile septic tanks, one of the advantages of which is the presence of a monolithic body, which excludes the possibility of waste entering the groundwater. To increase the strength of the body are supplied with stiffeners. In the model range of septic tanks of this brand there are compact models for a small cottage (capacity - 600 l / day) and high-performance (from 1200 l / day) products designed for permanent residence of a family of 5-6 people.

Triton

Triton septic tanks are compact single-chamber models of the "mini" class (Triton-Mini, Triton-Micro) and models for a large number of drains (from 1000 l / day) with three series-connected chambers (Triton-T). All structures are characterized by increased strength, capable of withstanding loads from soil pressure.

Topas

Models of this brand are energy-dependent (they belong to deep biological treatment plants - they clean wastewater by 98%), but differ from their counterparts in low power consumption. Reviews of septic tanks for a country house brand "Topas" prove their reliability. In addition, users note a large selection of products that differ in technical characteristics (performance, degree of deepening of the sewer pipe, method of draining, etc.).

If it is impossible to connect to a centralized one, choose the construction of an autonomous one. Here it is important to choose the right method of wastewater treatment. There may be several options. Consider each of them and determine which septic tank is better.

All about choosing a septic tank

Types of waste disposal devices

A septic tank is a watertight container in which wastewater accumulates or is processed. Classify the equipment according to such criteria.

All units dispose of wastewater, but they do it in different ways. The degree of purification also varies. Based on this, several types are distinguished.

Septic tanks

Tanks of various capacities, completely sealed. Most often they consist of one chamber, less often of two communicating compartments. Their function is to collect sewage, which is periodically taken out by a sewage machine.

Advantages

• Can be placed anywhere on . The main thing is to leave a free entrance for the car.
• There is no need to equip a post-treatment system, for example, filtration fields that occupy a significant area. Plus, they are hard to install.
• High resistance to volley discharges.
• Safe for the environment, provided that the tightness is not compromised.
• Energy independence and complete autonomy.

Flaws

There is perhaps only one drawback - the need for pumping.

Septic tanks

Consist of three or two chambers. In each, the liquid is purified. Depending on the design features and the type of "working" microorganisms, water is clarified by 40-75%. Thus, anaerobic microorganisms are able to purify the waste liquid by 40-60%.

Advantages

• Sufficiently high degree of wastewater treatment.
• Reliable durable construction.
• Electricity supply is not required.

Flaws

• Restrictions on installation in various types of soil.
• A permit for installation and operation is required.
• The need for regular cleaning of the first compartment from accumulated sludge. True, this happens much less frequently than pumping out the drive.
• A large area of ​​the underground part of the structure, taking into account infiltrators and drainage wells.

In addition, you will have to periodically buy bacteria and biofilters necessary for normal functioning.

Deep biotreatment systems

Multi-chamber system where waste is decomposed by chemical, biological and mechanical methods.

At the end of the cycle, 96-97% purified water comes out. It is considered technical, it is dumped into the ground or a reservoir. Post-cleaning is not required. A good quality of purification is ensured by the vital activity of aerobic bacteria and forced aeration. Possibility of installation in soils of any type.

Advantages

• Compactness.
• They take up little space, given that the installation of additional devices for post-treatment is not required.
• Regular pumping or cleaning is not necessary

Flaws

• The need to connect to the mains for the operation of aerators.
• Difficult service. It is good that it is regularly carried out by specialists. Independent intervention will lead to incorrect operation of the equipment.
• Restrictions on the use of household chemicals. Some of them provoke the death of aerobes.
• The price is higher than other types of equipment.

Differences in the type of appliances determine which septic tank to choose for a private house. For example, for, a septic tank is suitable.

Criteria for choosing a septic tank for a country house

A competent choice of a recycling device is impossible without taking into account several defining criteria.

materials

• Concrete monolith. Durable, very durable. It is erected independently, formwork is used for installation. Quite difficult to make.
• Reinforced concrete rings. Like the previous version, they are durable and last a long time. They need a secure seal. They can only be installed with the help of special equipment.
• or brick structures. Raised from the bottom of the pit. Effective sealing is required, otherwise the material is destroyed by moisture. Installation is difficult.
• Plastic tanks. Lightweight, relatively durable, low price. Insensitive to corrosion. Can be damaged by rodents, crack at low temperatures.
• Metal containers. More often from steel alloys. Durable, durable, sealed. Without effective protection, they are destroyed by corrosion.
• Fiberglass containers. Tight, lightweight, durable. Chemically inert, do not crack at low temperatures. They serve for a long time.

Dimensions

Calculated on the basis of the average daily flow rate. On average, one person per day accounts for 200 liters of sewage. According to the norms, the reservoir must contain at least a three-day norm for each resident. Plus, there is a reserve of 25-30% in case guests often come. The technical documentation of factory models always indicates how many people they are designed for.

The estimated volume of waste fluid determines the number of sections. So, if it is less than 1 cu. m, then choose a single-chamber utilizer, less than 10 cubic meters. m - two-chamber, more than 10 cubic meters. m - three-chamber. The dimensions of home-made devices are chosen arbitrarily.

Soil type and groundwater level

The geological situation of the area affects the choice. A sump with or infiltrate is placed only on sandy, pebbly and gravel soils, on plastic and sandy sandy loams. Groundwater should not reach at least 1 m to the structure. Clays, hard sandy loams, loams are not able to pass or absorb liquid. Therefore, it is impossible to put post-treatment systems on them.

Here, only discharge through sealed pipes into a centralized sewer or into ditches for drains is possible.

The best choice for clay soils would be sealed storage or bioremediation stations. Highly rising groundwater also does not allow the installation of sedimentation tanks complete with post-treatment. Only accumulators or biological stations are possible.

Homemade or Factory Made

Sometimes owners refuse to buy factory equipment. Make a choice in favor of homemade. Sometimes this is justified.

It is erected from concrete rings, monolithic concrete, brick. Provided that the installation is carried out correctly, a reliable durable construction is obtained. Sometimes old tires are used or just a pit is used. Such structures have a detrimental effect on the environment, polluting the soil around them. Factory containers made of plastic, and even more so fiberglass, will do the job better. Putting them in place is very simple. Septic tanks can also be made independently, but only the simplest models. After them, the liquid needs to be further cleaned, and equipment must be installed for this. If you need a completely safe, reliable design with a high degree of cleaning, you will have to buy it.

We conclude that a small drive is enough for a temporary home. The advantage of this solution is that the mini-tank can be installed independently. Houses with a permanent stay should be equipped with bio-cleaning stations. Settling devices equipped with post-treatment equipment can also be installed, but only if the terrain conditions allow it.
