12 best septic tanks

One of the most important issues when buying a land plot, summer cottage or a country house is the availability of communications. And if, as a rule, there are no problems with water or electricity, then the central sewage system in the private sector, especially in the distance 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 plant. Both types of devices for waste disposal use several stages of treatment: mechanical sedimentation of suspended matter, filtration and biological treatment. In autonomous septic tanks, anaerobic bacteria are used to process waste, which do not need oxygen, but act slowly. In volatile 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 cleaning device model depends on several factors:

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

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 treatment devices at their site;
• value for money septic tanks.

The best budget septic tanks for summer cottages

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

4 TANK-1

Tank-1 is the youngest model in the Triton Plastic line of non-volatile septic tanks. 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 purifying 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 stiffening ribs, which increases the service life and excludes the penetration of groundwater water into the internal volume 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 at this septic tank is 75 - 80%, therefore, it is recommended to use a special infiltrator complete with it, in which additional treatment takes place. 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 every few years.

3 Termite Profi 1.2

This miniature vertical septic tank can serve up to two people. Its effluent purification rate reaches 85%. Due to its low weight - only 80 kg, Termit Profi 1.2 is easy to transport and install. This is a great option for a small country house or a free-standing bath.An additional advantage - the thickness of the walls of the Termit Profi 1.2 tank reaches 20 mm, and the shape of the body is specially designed for optimal operation under load.

According to user reviews, this septic tank is easy to install and maintain. Experienced summer residents recommend that you definitely arrange the sprinkling of 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 at the site.

2 MICROBE 450

For a summer cottage, which is visited by 1-2 people, a guest house or a cabins for the period of building a house, the best option would be a budget septic tank Microbe 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 pillow, 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 constructive recommendations of the manufacturer.

Buyers 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, Microbe 450 is ideal.

As mentioned above, septic tanks are divided into autonomous and volatile. What is their feature, what are their strengths and weaknesses - we learn from the detailed comparison table:

1 Rostok Mini

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

Advantages:

• seamless, durable and lightweight (65 kg) plastic body;
• the presence of additional stiffening ribs to impart strength to the structure;
• completely blocks unpleasant odors;
• low, but stable performance;
• does not require frequent maintenance;
• attractive price.

Disadvantages:

• for its price category - does not.

The best volatile septic tanks

Purification stations, biological filters of which are inhabited by 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 dumped directly into the ground. Cleaning the tanks from silt is needed every couple of years, and the organic sludge itself is an excellent fertilizer for plants on the site. Since the drains do not need additional soil filtration, the structure takes up a minimum of space.

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

6 ERGOBOX 4

The body of this sewage 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 drainage volume sufficient for a permanent residence of 4 people. It is possible to choose both a gravity installation and an option with a forced discharge of wastewater for areas with a high groundwater level.

5 Tver-0.5P

The manufacturer's declared service life of this septic tank is 50 years. This becomes possible due to the fact that special structural plastic is used for the casting of the body, and the compressor equipment is made in Japan. The degree of water purification in this line of treatment facilities reaches 98%, which makes it possible to refuse additional ground filters.

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

4 Unilos Astra 5

One of the most famous septic tank models in 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 it 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 inlet of the drain pipe can be organized at heights from 0.6 to 1.2 meters above ground level, which greatly simplifies the installation of the tank.

Advantages:

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

3 Eco-Grand 15 (Poplar)

Dimensional volatile septic tank, ideal for equipping large country houses. Except that the container weighs 380 kilograms, there are no installation problems. And in terms of operational indicators, 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 effluent enters the receiving chamber (a salvo discharge can reach 450 liters), due to aeration, the solid fractions begin to decompose.

In a separate compartment under the control elements there is a compressor for pumping waste water through the system. By the way, the latter consumes in general up to 2.8 kilowatts of energy per day - not much, but over a long time of operation, a decent amount accumulates.

Advantages:

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

Disadvantages:

• high price;
• increased power consumption.

2 TOPAS 8

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

Advantages:

• popularity with users;
• low power consumption;
• highly efficient filtration;
• reliable case;
• ease of use and low maintenance requirements.

Disadvantages:

• not detected.

1 GRINLOS Aero 6 Pr low body

A novelty in the market of autonomous sewers. Ideal for areas with high groundwater levels. The station body is divided into 5 compartments, which allows you to independently service the station. This is a practical model of the station, which is distinguished by a special design - the body has a reduced size compared to other representatives of the line. The station is suitable for 6 users.

Among the features of the station is the automatic discharge of treated wastewater. Treated water is directed through a pipe at an angle to a drainage well or trench. The compressor, together with all electrical equipment of the station, is located in a sealed compartment under the cover, which provides protection against moisture and dampness. This compartment is not simply separated from the main neck, as is the case with most manufacturers. Additional space is provided here, which allows you to reliably isolate electrical equipment. There is also a ventilation fungus on the lid.

Pros:

• The station is made of virgin polypropylene.
• The degree of wastewater treatment reaches 99%.
• Ideal for areas with high groundwater levels.
  Low running costs.
• The manufacturer's warranty for the station body is 5 years.
• Constant maintenance is not required.
• There is no need to comply with complex requirements when installing equipment.
• The cleaning station does not require expensive components to operate.

Minuses:

• Not found

The best self-contained septic tanks

Autonomous septic tanks that do not require an electrical connection are the best option for a summer cottage or a country house in a remote area where there are problems with electricity. Their design contains no moving mechanical parts, so they are simple, reliable and will perform in any case.

Of course, there are also disadvantages - lower productivity, worse level of effluent clarification. The best models provide no more than 85% purification, and, therefore, the water needs additional filtration. There are several ways - drainage fields, infiltrators, filtration wells - and they all mean additional cash costs and reduce the usable area of ​​the site. 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

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 effluents without problems (but not ideal), and also does not impose high requirements on maintenance. The problematic place, judging by the feedback from users, is the extreme intolerance to the diversion of rain and drainage water to the local treatment system. Why this is happening is a matter of acute discussion. But the fact that this is an obvious disadvantage is supported by all and unanimously.

Advantages:

• good standard filtration performance;
• high-quality body materials.

Disadvantages:

• ingress of rain or drainage water into the treatment system leads to a deterioration in filtering capacity.

2 Termit Profi 3.0

The productivity of this model, which uses the principle of anaerobic effluent clarification, is 1200 liters per day. At the same time, the cleaning level reaches 85%, which allows minimizing the area of ​​the final soil filtration. Such a septic tank with a sufficient supply ensures the permanent residence of 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: preserving 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

This is a relatively inexpensive option for a purification system for a summer cottage or a country house, where there are significant problems with the power supply. The productivity of the model is 700 liters per day, which meets the needs of 4-6 people. At the same time, the septic tank does not require an electricity 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. Disadvantages of the device - 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 where a family of 2-3 people lives, but guests occasionally come.
