Which septic tank is better - features of choosing a septic tank for home and garden. Choosing a septic tank for a summer residence: which is better, device, characteristics, reviews The most effective septic tank for a private house

For comfort in a country house or in a rural area, you will need to connect water supply and sewerage.

The best option for autonomous collection of wastewater was a septic tank.

The owner of the house faces the problem of choosing the best option of such treatment facilities from the many offered on the market.

What are they like

Compact treatment facilities serving the needs of one house are divided according to several criteria:

• way of working;
• materials used;
• Shape, location and type of installation.

Variety by way of work

For a summer residence or a private house, septic tanks are suitable: from the simplest, accumulative to fully functional, carrying out high-quality complete wastewater treatment.

Cesspool or storage tanks

In fact, such a septic tank is an improved cesspool.

It is a sealed container, the only function of which is to accumulate effluent from the house.

In the chamber, they are divided into fractions– heavy waste sinks to the bottom, light waste, such as fats and oils, accumulates on the surface.

The advantage of this kind autonomous structures- the simplicity of the device.

Main disadvantage storage septic tank - the need for its regular cleaning, for which specialized sewage equipment is involved.

Cesspool option is suitable for a house in which the volume of regular drains is small, for example, for a summer residence, with 2-3 people living and limited water consumption.

The main requirements for a cesspool septic tank- sufficient volume, tightness and high strength of the storage tank.

Their implementation will reduce the frequency of cleaning and protect the environment from the ingress of waste accumulated during operation.

Settling tank with soil post-treatment

Overflow septic tanks are a great option for a home where the daily glass size is small, but people live and use the water supply all the time.

In such structures, in addition to the accumulation of waste, their partial processing and purification takes place.

Removing accumulations for such an installation required much less often - as a rule, overflow septic tanks need the services of vacuum cleaners no more than once every 2-3 years.

Principle of operation

Overflow septic tanks - two-chamber. The first chamber, which receives effluent from the house, acts as a sump.

After partial separation into fractions, water with a minimum content of solids coming, including from under, flows into the second chamber - treatment.

It uses aerobic bacteria that can decompose organic matter to process pollution.

The degree of water purification as a result of their work reaches 60-70%.

Such water is used for irrigation or is discharged into natural reservoirs, undergoing additional purification along the way in soil filtration fields.

They are layers of rocks with high water permeability (gravel or crushed stone with the addition of sand, etc.), which remove pollution according to the principle of mechanical (mesh) filters.

Advantages of such a septic tank:

• ease of maintenance;
• a significant time interval between tank cleanings, due to a decrease in the accumulation of dry residue;
• processing a significant part of the waste contained in the effluents.

Deep biological processing of waste

Such facilities are full-fledged wastewater treatment plants.

They process large volumes and are suitable for a large private house with permanent residence.

At the same time, biochemical septic tanks purify water by almost 100%.

The design uses three chambers:

• to separate the substances contained in the drains (read how to connect the automatic washing machine to the sewer) by fractions;
• biological treatment with the help of aerobic and anaerobic bacteria (to ensure the activity of bacteria, additional equipment is used - aerators);
• disinfection using chemicals.

Advantages of three-chamber septic tanks:

• 100% degree of wastewater treatment;
• absence unpleasant odors when using such installations;
• no restrictions for installation by type of soil and groundwater level;
• minimum costs for installation and time for commissioning - the stations are delivered fully equipped;
• minimal human involvement in the work, since the system is unattended.

For septic tanks with this degree of cleaning, the frequency of replacement of chambers or the selection of dry residue from them is once every 5-8 years, due to its minimal accumulation.

The main disadvantage of such treatment facilities is high price(how to make a do-it-yourself sewer grease trap is written in the article).

Important! If the mode of living in the house involves long breaks, for example, suburban area the absence of people in the house in the winter season, septic tanks with biological filters are not installed.

The limitation is due to the fact that without a regular income growth medium cultures of bacteria that process organic waste, will die.

What are the criteria for selecting wastewater treatment plants?

Choosing a septic tank for construction or installation of a finished product requires taking into account several important factors.

Performance

The possibility of processing the entire volume of wastewater generated in the house (productivity) is the main technical indicator of a treatment plant.

It depends on the number of people living in the house, and the level of use of plumbing fixtures.

Naturally, in a country house where 2-3 people live in the summer, and the main consumers of water are a wash basin and a shower, the volume of effluents will be much less than in a comfortable cottage intended for permanent residence of a family, with:

• swimming pool,
• multiple bathrooms (),
• with washing machine and dishwasher.

In practice, in terms of performance, septic tanks are selected based on:

• with a daily volume of effluents less than 1 cubic meter, a single-chamber storage septic tank is sufficient;
• if the volume of the drain lies in the range from 1 to 10 cubic meters per day, a two-chamber septic tank with soil filtration is installed;
• with volumes exceeding 10 cubic meters / day, a three-chamber deep cleaning septic tank would be the best option.

Note!

When installing a storage septic tank in the country (about laying external engineering networks and communications read on the page) you should take care of its regular cleaning.

If the volume of wastewater turns out to be significant, the call for a sewage truck will have to be done often.

In terms of costs, this can be more expensive than installing a more advanced two- or three-chamber model.

Important! SNiP install the minimum required size of the septic tank chambers. It must contain the amount of waste generated in the house within 3 days.

Type of soil on the site and the depth of groundwater

This factor matters only if the choice is made in favor of a septic tank with post-treatment of water in the filtration fields.

Soils are suitable for its installation with high water permeability. On heavy clay soils, the organization of natural filtration is difficult.

In this case, it will be necessary to excavate part of the soil, replacing it with a mixture of crushed stone and sand. Carrying out these works will require time and a significant amount of investment.

Septic tank of biological and chemical treatment will be more profitable.

Comment! For the organization of a storage septic tank, the type of soil only affects the labor intensity of work on preparing the site and building the structure.

Sorting by materials of manufacture

For autonomous treatment facilities, septic tanks are built on site or purchased industrial options.

The first include brick septic tanks, monolithic or precast concrete, improvised materials.

More expensive, but, undoubtedly, absolutely, a ready-made septic tank will become a reliable option.

In the assortment of manufacturers - stations with cases made of polymers or fiberglass.

Advantages of purchased products:

• wide selection in terms of performance - from mini-septic tanks, sufficient for a house with 1-2 people, to semi-industrial installations that can process the effluents of a small village;
• absolute reliability and tightness;
• delivery of ready-to-work devices, thereby reducing the time to commission the plant;
• complete set with all necessary equipment and means of cleaning.

Attention! Septic tanks with housings made of polymers or fiberglass require protection from floating when the groundwater level rises and destruction under pressure of soil masses or displacement of soil layers.

For this purpose, purchased stations are installed in concrete pits, and they are anchored - fastening the tanks to the walls and bottom of the pit with nylon straps.

Installation options

Both purchased installations and septic tanks own production- Available in vertical and horizontal versions.

Vertical structures are designed for installation with deepening into the ground.

This is their problem - on heavy soils or when groundwater is close to the surface, installation work is labor intensive and requires the use of special equipment and special tricks to ensure reliability and environmental safety.

Horizontal septic tanks are usually an option for surface mounting.

To ensure the required performance (volume of runoff), such structures occupy a significant area, which creates additional problems for limited land ownership spaces (for example, in summer cottages).

How to understand which septic tank is best for a house with permanent, year-round living? Watch the video and get answers to your questions about efficient household waste collection and recycling equipment.

When erecting country house or cottages primarily design a water supply and sewerage system. Especially if there are no centralized communications nearby. And in this project, an important role is played by the wastewater disposal and treatment system, for which it is necessary to choose the best septic tank for a summer residence from all offered. modern market types.

A reservoir is a reservoir in which all wastewater from all plumbing points of the house and undergo biological treatment with subsequent drainage of the liquid into the soil or its pumping out using assinization equipment.

In order to understand which of the tanks to install in a particular suburban area, it is worthwhile to conduct a thorough analysis of all types of equipment, understand the principle of their operation and evaluate the feasibility of installing one or another type of treatment system for private sewer.

We analyze the varieties of septic tanks in our material and find out which of the tanks is the best.

The modern plumbing industry offers the consumer septic tanks, which can be classified according to several criteria. First, we will analyze the treatment systems according to the method and principle of operation, after a thorough analysis. There are such types of septic tanks:

• storage tanks;
• Septic tanks operating on the principle of soil filtration;
• Tanks with a system of deep bio-cleaning.

More details about each type of equipment below.

Septic tank accumulative

This type of private sewer equipment is a durable sealed reservoir for collecting all domestic wastewater from the site. In principle, such a container resembles a standard cesspool, with the only difference being that the storage septic tank does not have walls in the form of soil. In this case, when installing a treatment system, the tank is simply buried in the ground to the required depth.

The principle of operation of such a treatment system is that the effluents are collected in containers where the natural decay of effluents occurs. That is, their larger and heavier particles settle to the bottom of the tank, and light water and fatty films rise up.

Such a structure requires periodic cleaning with a vacuum cleaner.

Important: when conducting an analysis, choosing and installing a storage septic tank, you should carefully select the container according to the volume and material of manufacture. In the first case, the volume should allow a certain amount of wastewater to accumulate freely for a specific period, so that you do not often have to call in special equipment to remove them from the tank. As for the material, it must be strong enough so that the soil does not crush it during operation. To this end, a thorough analysis is also recommended.

Most often, the device of such a septic tank is used in cottages or houses. country type in which they live not permanently, but seasonally.

Septic tank with soil filtration

These types of septic tanks are used in those houses where the household is supposed to live permanently and where the amount of drains will be the same constant. This type of equipment requires less frequent cleaning using special equipment.

The principle of operation and the device of such a treatment plant are quite simple and are as follows:

• Effluent from the entire house flows down the pipeline into the first chamber of the reservoir, where it flows into light water and heavy solid inclusions. The first through a special drainage hole goes into the second chamber of the septic tank, and the remaining heavy debris settles to the bottom of the first drive. In the second chamber, water undergoes bacteriological post-treatment and after that it is sent through the connector to the filtration fields of the third chamber, from where it freely seeps into the soil.

Important: in order for the bacteriological decomposition of wastewater in such a treatment plant to be faster, it is better to use special aerobic-type bacteria that will not only process the wastewater, but also eliminate their unpleasant odors from the septic tank.

After analyzing the septic tanks, it was possible to identify the following advantages of this type of equipment:

• High speed and quality of domestic waste water treatment;
• Pretty simple tank maintenance;
• No need for frequent use of sewage equipment.

Important: it is forbidden to build and operate these types of septic tanks in areas with clay soil or in areas where groundwater is high. In this case, all drains, instead of draining into the soil, will simply wash away the area.

Septic tanks with deep biological wastewater treatment

These types of septic tanks are found wide application practically in all areas and on any objects. Main Feature of such a device is high-quality wastewater treatment to the state of water that is safe for environment. Residual organic matter can be discharged from such a treatment plant directly into the ground or even water bodies. This is evidenced by a qualitative analysis of water taken for a sample from a septic tank of this type.

In settling tanks with a bio-treatment system, complex wastewater treatment is used:

• Simple settling of water;
• Its bacteriological purification;
• And chemical processing.

The principle of operation and the device of such a treatment plant are as follows:

• First, all domestic wastewater enters the first chamber of the tank, where it is divided into water and larger fecal inclusions. After that, the clarified water is transported to the second chamber, where aerobic or anaerobic bacteria are used.

Important: in order for aerobic bacteria to work more efficiently, a special compressor that pumps oxygen is installed in the second chamber of the septic tank.

After the organic masses acquire a structure of simple composition, they are transported to the third chamber, in which chemical post-treatment of water is carried out. Now the effluent is ready to be discharged into the ground or a reservoir.

According to the analysis of all three types of containers, this one has the following advantages:

• High quality wastewater treatment and treatment;
• The possibility of using such treatment facilities on soils of any type;
• Absence of sharp unpleasant odors from the sewage tank;
• Ease of installation of equipment and its operation (the septic tank works independently without the need for constant monitoring of it);
• The presence of a small amount of final sediment, which allows you to clean the tank quite rarely (1 time in 5-8 years).

Important: a septic tank with a deep purification system requires connection to the electricity network, which entails the need additional costs to pay utility bills. But, after comparing all three types of septic tanks, we can safely say that such expenses will pay off with a vengeance in the absence of the need to use sewage equipment with enviable regularity.

Septic tanks by type of material

All purification tanks can also be divided into categories and according to the type of material used for their manufacture. Since the use of certain types of containers is relevant for one type of soil and may not be suitable for another at all. Therefore, it is necessary to analyze all the capacities offered by the market.

So, we compare septic tanks by type of material. Reservoirs are:

• Brick cleaning systems;
• Concrete tanks;
• Metal tanks;
• Plastic containers.

Brick septic tank

Most standard type treatment tank at the dacha or suburban area. The popularity of such containers is due to the ability to use waste building materials, which saves the family budget.

When building a septic tank from brick, it is necessary to observe the tightness of its walls, since building stone can create cracks and gaps when laying. To avoid this, you can use a sealant or penetrating mastic.

Important: in addition to saving money from family budget such a treatment plant is quite advantageous from the point of view of its construction. There is no need for sophisticated technology or professional skill. Masonry can be done in one brick with your own hands.

Concrete tanks

A feature of the construction of tanks made of concrete is the need to dig a pit. If the septic tank is very large, then you will have to use sophisticated equipment.

Two types of treatment facilities can be built from concrete:

• Monolithic;
• Made.

In the first case, a pit is dug and reinforced concrete is poured into the installed formwork. In the second case, the septic tank is assembled from concrete rings. They are mounted one by one.

Important: for a container made of reinforced concrete rings, it is necessary to monitor the tightness of the joints.

Metal septic tanks

The rarest type of tanks for wastewater treatment. The analysis shows that such containers have rather negative features than positive ones. And the most important of them is metal corrosion, which one day will lead to depressurization of the cleaning system.

PVC septic tanks

Comparison of septic tanks from different materials definitely speaks in favor of plastic. Such containers are made of sand-reinforced polymers by hot extrusion (extrusion under high pressure). The result is a strong container that can withstand high mechanical stresses in compression and tension. Especially if the tanks have special stiffeners.

The features of such tanks are entirely positive:

• Strength and durability;
• Resistance to aggressive environments;
• Environmental friendliness of materials;
• Excellent 100% tightness of the treatment system;
• Light weight.

The last advantage can also play the role of a disadvantage. So, plastic containers for a septic tank are at risk of being thrown out of the ground under the influence of temperature changes and groundwater. To prevent this from happening, they (PVC tanks) are installed in special pits with subsequent concreting. And you can use a special anchor system for their installation.

There are also septic tanks from any materials at hand. But this type of equipment is not professional and is used most often in small summer cottages, where the owners come periodically to harvest or harvest for the winter. In this case, you can use simple barrels, car tires, etc.

Construction of septic tanks

According to the type of construction, septic tanks are distinguished as one-, two- and three-chamber. The latter are performed if it is planned to install a treatment plant with a biological post-treatment system.

Two-chamber - these are tanks for a sewage treatment plant with a soil cleaning system. Single-chamber septic tanks are accumulators.

According to the installation method

All septic tanks can be divided into vertical and horizontal according to the method of mounting the cameras. So, in the first case, the tanks are installed with their bottoms in the ground and look like a simple barrel with hatches in the upper part. With this method of installation, the treatment system goes deep and occupies less space Location on.

If the septic tank is installed vertically according to the type of tank, then here, on the contrary, the depth of occurrence will be less than the occupied area.

Important: vertical treatment structures are used where the groundwater level is high enough.

In addition, it is worth noting that septic tanks are surface and underground. The former are also used on those soils that are washed large quantity groundwater located close to the surface of the earth.

Underground - are installed in all other cases.

Which of the types of septic tanks to choose for a summer house or a country house, and which options are right for your site, must be decided depending on the following parameters:

• Quantity and volume of sewage on the site;
• Frequency of residence or stay on it;
• Soil characteristics of your site.

Remember, a properly selected and installed septic tank will effective tool for cleaning and drainage of all domestic wastewater.

Which is better to choose a septic tank for a summer residence? The question is not idle. Equipping a private house or cottage with a sewer system becomes a problem for many owners. After all, many cottage and holiday villages simply do not have the ability to connect to centralized system waste disposal. But there is a fairly simple solution to this problem - a septic tank for a summer residence or a private house, and for small plot fit model mini-septic tank.

You can choose a septic tank for your home based on reviews or technical specifications, photo and video instructions. But it is best to choose several septic tanks, focusing on technical specifications, and choose a specific model based on customer reviews and photos.

What it is?

A septic tank is called an autonomous treatment plant for liquid waste, which is installed in a private area with both low and high groundwater. I visit septic tanks various designs and different power. Installing a septic tank is able to ensure the full functionality of toilets, showers and bathtubs, sinks, as well as all necessary household appliances (washing and dishwashers). If this is not required, then a mini-septic tank model is quite suitable.

A septic tank for a house with high groundwater is the best alternative to the well-known cesspool. After all, using it with modern materials and technologies is a crime against yourself and the environment. Unlike a septic tank, it is harmful to the environment, violates all hygiene standards, and besides, it also has a constant strong unpleasant odor. But installing a septic tank in your summer cottage will save you from these problems. You can buy a septic tank for a summer cottage without pumping out, then it is almost not required to care for it.

A septic tank can be both factory-made and home-made. However, reviews homemade septic tanks testify to some negligence of individual authors in the proposed schemes for the operation of septic tanks. Right choice septic tank and quality installation guarantees long and uninterrupted operation of the sewer for a period of at least 10 years.

Advantages of septic tanks for summer cottages:

1. They are easy to install:
2. Eco-friendly:
3. Do not require special costs in operation;
4. Their installation cost is relatively low;
5. Guaranteed high level wastewater treatment due to the anaerobic process;
6. A variety of models allows you to choose a septic tank, both for a small country house, and for a large country cottage or residential complex;
7. Suitable for installation in any climate zone, even in areas with high groundwater;
8. When properly installed, they are reliable and durable.

Principle of operation

There are several types of septic tanks for summer cottages, but they all work on a similar principle - this is a large tank, divided into several chambers. The chambers are equipped with filters and in each of them a certain stage of cleaning takes place:

• Physical cleaning, which separates large debris;
• Sedimentation of wastewater in the sump;
• Decomposition of organic waste;
• Anaerobic treatment;
• Removal of the formed gas;
• Filtration and clarification of wastewater.

All this allows you to clean drains to very high rates (up to 98%), although for some models it is necessary to additionally install aeration fields. But there are septic tanks in the country without pumping out, which guarantee a high degree water treatment with minimal cost, but it's hard to call them budget. And this, judging by the reviews and photos, the procedure is very expensive.

Types of septum

Which is better to take a septic tank for a summer residence? After all, comfortable living in the country depends on it. There are several features by which septic tanks are classified. This is the design, principle of operation and material of manufacture. Well, let's not forget about the reviews and photo reports of specific users. They will give you an idea of practical use septic tanks.

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

1. Cumulative. They are one large reservoir in which wastewater is collected and settled until pumped out. It is this design that is most often chosen to create a homemade septic tank.

A cumulative septic tank for a summer residence has a number of advantages:

• Low cost. Some craftsmen collect it from improvised material, such as tires;
• Easy to install;
• Suitable for areas with high groundwater;
• Autonomy.

But the disadvantages of this septic tank for giving still outweigh, judging, again, by the reviews:

• Only suitable for sandy soil;
• Not designed for salvo discharges of water;
• Small volume;
• Septic tanks without pumping are expensive;
• Requires regular pumping;
• The need to often resort to the services of vacuum trucks;
• Most often it has an unpleasant odor.

1. Anaerobic septic tanks for summer cottages with infiltration fields. This is a large tank, divided into several small sections, where the effluents go through several stages of treatment until the organic waste is completely decomposed. Effluent in this case is cleaned up to 75%. Since this indicator is quite low, it is necessary to additionally install anaerobic fields in the system. Analyzing the reviews, we note that these septic tanks have no fundamental shortcomings, except for the high cost of septic tanks without pumping.

1. Aerobic septic tanks for summer cottages. This type septic tanks guarantee up to 98% wastewater treatment thanks to anaerobic bacteria that completely decompose all waste, and the filter system completely purifies and clarifies water. Often such septic tanks are equipped with additional pumps, air vents and air compressors. Most models are septic tanks without pumping. This is the most expensive, but at the same time the most effective type of septic tanks for summer cottages. And judging by the reviews and photo reports, this is their main drawback.

You can also classify septic tanks for summer cottages according to the following criteria: factory-made or home-made, autonomous or volatile, underground or ground, requiring pumping and not requiring.

Production material

Which septic tank to choose according to the material of manufacture. For the arrangement of a septic tank, three types of containers are most often used:

• Plastic. Lightweight and durable tanks that are easy to install and maintain. Their service life is quite long and, with proper installation and use, they will last up to 50 years. The installation of small models does not require the use of special equipment. There are septic tanks without pumping, and with storage. But the small weight of the structure is also a disadvantage - the septic tank can "float" to the surface of the soil with an increase in groundwater. Reviews indicate that because of this, such septic tanks cannot be installed in places where groundwater comes out to the surface. Or, in order to avoid the "floating" of the septic tank under the influence of rising groundwater, it is concreted or "anchored" with special belts. So this is not the best option for a septic tank for a summer residence with a high level of groundwater.
• Concrete. good type a simple and durable septic tank for a summer residence. The structure is very durable, does not corrode, but has a lot of weight. There are two options for building the device. The first is the installation of ready-made factory concrete rings using special construction equipment. The second is pouring concrete into the finished formwork and gradually erecting the structure. it best option septic tank for summer cottages with high groundwater.
• Metal. They have a relatively small mass, which makes installation very easy, and an acceptable cost. necessary equipment make them quite popular among developers. But they also have a drawback - a very high probability of corrosion due to anaerobic processes, the service life of the device is greatly reduced. Suitable for areas with high groundwater.

Device, schemes

Which septic tank to choose according to the arrangement scheme? There are a lot of variations of septic tanks for summer cottages, ranging from a home-made sump from used tires to very complex multi-stage cleaning models from various manufacturers.

Any design of a septic tank for a summer residence consists of several chambers:

• loading capacity for waste;
• additional cleaning chambers with filters and an anaerobic chamber.

Often additional storage tanks and aeration fields are used.

For equipment summer cottages or houses where 3-4 people live, most often they use mini-septic tanks for summer cottages, that is, models that are designed to process 0.7-2 cubic meters of wastewater. Such mini-septic tanks have a number of advantages:

• mini dimensions, which makes installation easy;
• a factory mini-septic tank is most often inexpensive;
• building a mini-septic tank with your own hands is much cheaper than buying a finished product;
• operation of a mini-septic tank is economical;
• there are mini anaerobic, accumulative and infiltration models;
• mini-septic tank is very easy to maintain;
• with the installation of a mini-septic tank, just a couple of people can easily cope without the use of construction equipment.

Buying a large septic tank makes sense only when a large number of people live in the house, and a mini-septic tank for giving is ideal if you visit the site only on weekends. But such models require additional reinforcement in areas with high groundwater.

Calculation

Choose suitable septic tank for a summer residence is a complicated matter. After all, the life support system of the entire house or cottage depends on it. In order for the choice to be successful, it is first necessary to accurately calculate the mode of operation of the sewer and the volume of effluents.

It is on these parameters that the characteristics of the septic tank for giving, which you should pay attention to, depend. You also need to decide - an autonomous or non-volatile sump model will suit you, or will a septic tank connected to the mains suit you?

For example, 3 people live in the country house, which means that the volume of the septic tank must be at least 600 liters. Based on the guests, even a little more. And for the correct operation of the entire system, protection against volley drains and to ensure the operation of household appliances, this number must be multiplied by 3 again, that is, 600x3, and we get a number of 1800 liters per day. On the this example it can be seen that in most cases it is enough to install a mini-septic tank, and not a large-sized model.

Popular manufacturers

Our market offers a wide range of septic tanks for summer cottages from various manufacturers. The most popular of them are trade marks Topas, Eurobion, Poplar, Tank, which offer autonomous sewer systems from plastic.

Their products are a wide range of models of various capacities - from small septic tanks for cottages with a wastewater volume of 1000 liters, to large tanks for hotels and large residential complexes. According to the principle of work - anaerobic and aerobic. They also differ in cost - the most affordable are the systems of the Tank company, and the most expensive are Topas. But all of them have proven themselves well with the owners of private houses, cottages and summer cottages. In the photo you can see their dimensions and shape.

Help in choosing

Before buying or installing a septic tank for a summer residence, several issues must be resolved:

• optimum building size. According to the form presented above, it is necessary to calculate the amount of wastewater. If there is no shower and bath in the dacha, then a hundred liters can be deducted from the total volume of drains .;
• place of installation. It depends on this optimal shape septic tank. For small summer cottages, it is recommended to choose vertical models. But remember that the sump cannot be located close to water bodies and buildings;
• budget. The quality and functionality of the sewage system and the method of installation depend on it. Of course, the best solution would be to purchase a finished structure with the deepest degree of cleaning and install it on a turnkey basis. But this is not advisable for houses with a seasonal residence of a small number of people.

Remember that a septic tank for a summer residence differs in functional tasks from a septic tank in a private house. The country sewerage system should solve the following issues:

• it should be designed for periodic burst discharges of wastewater;
• country sewerage should be suitable for seasonal conservation in the autumn winter period.

Prices for septic tanks

In search of an answer on which septic tank to choose for a summer residence, many buyers pay attention to the price of a septic tank. How to buy a quality septic tank without paying extra money?

The average price of a small mini-septic tank of a simple design for a dacha is about 20,000 rubles, more complex models cost more depending on the volume and model. The price of complex sewer systems with aeration is about 150,000 rubles.

Like any other product, septic tanks are presented in large quantities on our market, you can go to the store or see the photo in the catalog. Varieties of designs and models, their price range is very wide, and sometimes it is very difficult for a non-specialist to figure out which is better to choose a septic tank. In this case, it is necessary to take into account your own capabilities and budget, and do not forget about the ratio of cost and quality.

Wanting to buy inexpensively, many summer residents prefer to install a septic tank for their home with their own hands, rather than buying a factory system. In this case, a concrete septic tank for the house will cost 20-30 thousand rubles.

The most inexpensive septic tanks are storage and home-made, and the most expensive are models with several stages of processing and aeration that do not require regular pumping. But which one is better - everyone must decide for himself - after all, it is not always advisable to install an expensive septic tank for a small dacha where no one lives permanently.

• the price of all consumables;
• the price of installation work, if there is a need to involve hired workers.

To set which better septic tank to purchase, moreover, inexpensively, it is necessary to study the assortment of stores and catalogs of manufacturers. Here are some examples of prices at which you can buy septic tanks, and their photos can be viewed on the manufacturer's website:

• "Bionic" with a volume of 1.5 m³ will cost 38,000 rubles;
• "Tver" with a volume of 2 m³ - 70 thousand rubles;
• "Tank-1" with a volume of 1 m³ -17,000 rubles;
• "Triton" for 2000 l. - 24,000.

Convenient when a private house connected to centralized sewerage. But if this is not possible, then you should think about installing a local waste disposal system - a septic tank.

It allows you to save the site from pollution, and in some cases makes it possible to get from the drains process water for watering plants, washing cars, etc.

At the same time, the operation of the septic tank is based on a simple principle.

Whatever the cleaning device, its operation is based on 3 principles:

• sedimentation of large suspensions;
• floatation of light pollutants;
• biological decomposition.

All septic tanks consist of several chambers. The first 2 stages of cleaning take place in the first tank. The branch pipe leading to the next chamber is located in the center, draining water, in which there are no longer suspended suspensions and heavy fractions. The type of biodegradation and its effectiveness depends on the type of apparatus.

On the video you can see the process of water purification in a septic tank:

Types of septic tanks for a private house

The classification of the wastewater treatment system into types is based on the dependence on electricity, the type of biodegradation and the material from which the septic tank is made.

Anaerobic and aerobic varieties

In simpler designs, anaerobic (oxygen-free) decomposition of contaminants occurs in the second and subsequent tanks. Such cleaning is not complete and requires an additional stage of soil filtration: filtration wells or filtration fields.

In them, the remaining contaminants are retained by the filtering backfill, on which a film of microorganisms is additionally formed, continuing the process of biooxidation.

Local treatment plants more complex and efficient designs. They mimic large sewer effluent treatment systems.

There are also several cameras in the LOS. In addition to settling and anaerobic decomposition, such a device has a compartment in which aerobic microorganisms (activated sludge) break down pollution in the presence of oxygen.

After that, the water enters a special sump for the settling of activated sludge, which is pumped out by the airlift into the stabilization compartment. Part of the sludge mass is again fed into the aerobic treatment tank. Precipitated dense sludge must be periodically removed from the tank.

There are also storage tanks in which water does not undergo any treatment other than precipitation. They only collect and periodically remove wastewater. Storage tanks can only be conditionally called a septic tank, this is a cesspool - a cheap option to install, suitable only for small country houses with little stock.

Dependence on electricity

It is important to know this principle of classification of waste disposal systems, since not all country houses have access to an uninterrupted supply of electricity.

1. non-volatile are simple devices, where anaerobic oxidation of organic matter is carried out, and water is poured between the reservoirs and to the stage of soil post-treatment by gravity.
2. VOCs do not work without electricity necessary for the operation of the compressor supplying air. Also, in many models, wastewater from one chamber to another and activated sludge are pumped by airlifts powered by a compressor.

Anaerobic devices depend on electricity when, due to the nature of the landscape, it is necessary to install a pump to transfer liquid to the soil filtration stage.

What and how to make a septic tank?

Waste treatment tanks can be made from a variety of materials.

1. There is finished plastic tanks. You can make them yourself from several plastic pipes large diameter or eurocubes. Mounting such containers is quick and easy, without the involvement of special equipment. They are durable and recent times are the most popular.
2. metal containers may be ready. They can also be welded from several sheets. Such tanks are rarely used, mainly when it is necessary to place the container at a great depth. From the inside, to extend the life of the container, it is recommended to treat it with an anti-corrosion compound.
3. brick- budgetary, but physically expensive material. Brick is laid on concrete base. The cross section can be round and with right angles.
4. Septic tanks from concrete rings- one of the most traditional options. Products with a diameter of about 1 m are used, which are installed on top of each other. For their delivery and installation, it is necessary to hire a truck and a crane. Concrete containers often leak at the junction.

Budget, but not very reliable tanks are made of wood, tires from truck wheels.

When choosing the type and model of the device, it is necessary to correctly make calculations, take into account the features of the site.

An important factor is the price of the finished station.

How to choose a septic tank for a private house?

The simplest and most reliable option is a ready-made plastic septic tank. There are enough companies offering such products now. Before buying or self-constructing a septic tank for a toilet, you need to decide on several parameters.

Performance

The required capacity and volume are determined by the number of inhabitants. If guests will periodically live in the house, then they must also be taken into account in the calculations. On average, one person generates 200 liters of wastewater per day.

For a family of four, equipment with a capacity of 800 liters is required. Since wastewater can be in the tanks for 3 days, then power received must be multiplied by 3 to get the volume value. For our example, we need tank with a volume of 2.4 m 3.

natural conditions

Features of the relief, soil and climatic conditions are also important not only at the installation stage, but also at the purchase stage.

1. You need to know the depth of soil freezing, because the pipeline and its entrance to the tank must be below the zero point. There are special ready-made models with an elongated neck and a low inlet.
2. Samo equipment is recommended to be installed where there is an elevation to protect against atmospheric moisture.
3. If the landscape does not allow gravity to remove effluent from the reservoir, then you need to choose a model with forced evacuation of the purified liquid, in the last chamber of which the pump is located.
4. For clay soils prone to bursting during freezing we need structures with especially strong walls: concrete, plastic with stiffeners.
5. For soil post-treatment, it is especially important to know the type of soil. The best option is sandy soil. In other cases, the arrangement of filtration fields requires a lot of effort.

Cost and popular models

Each owner takes into account the price of the waste disposal device. But here it is better not to save.

The best option is to purchase ready-made equipment.

Below are prices for popular models designed to serve 4-5 people.

1. Popular septic tank with soil aftertreatment Tank 2.5 in full set from 36 thousand rubles.
2. Proven Poplar 5, related to complete biological treatment plants, can be purchased at least 72,000 rubles.
3. Topas 5 also provides a high degree of wastewater treatment. The cost of such equipment about 80,000 rubles.
4. If you are looking for a septic tank for a summer residence, then a good option could be "Triton-mini", with a volume of 750 liters. Together with the soil filtration system, it costs about 22 thousand rubles.
5. More and more positive reviews are gaining and LOS "Unilos Astra-5". You can become the owner of this system for about 80 thousand rubles.

Many users have already seen the reliable operation of these devices. In addition, they are all simple and for self-assembly.

Device and installation of septic tanks

Installing a wastewater treatment device is quite simple, especially a ready-made plastic container, to which instructions are attached. First you need to choose the right place.

1. From the foundation the house to the septic tank must be at least 5 meters. But you don’t need to install too far, otherwise you need a revision well.
2. Distance between trees and a septic tank 3 m.
3. From rivers and reservoirs to the wastewater treatment device should be 30 m, and from wells and wells - 50 m.
4. Roads should not pass over the filtration fields.

As mentioned above, it is important to know the depth of soil freezing, which is indicated in SNIP 2.02.01-83 * for each region of the country. Pipes and soil filtration elements must be located below the zero temperature point.

Based on all these data, a septic tank is installed in accordance with with step by step instructions.

1. They dig trenches under a slope for pipes and a foundation pit for the septic tank itself.
2. A layer of sand 10 mm thick is poured into the ravines, it is rammed, always observing the slope.
3. Construct a sand and, if necessary, a concrete cushion in the pit. It must be even.
4. Install a septic tank exactly.
5. Connect it to the supply pipes, as well as a pipeline leading to soil filtration or a collection tank.
6. Fall asleep pipes and tank. It is important to pour liquid into the container, the water level should be 150 mm above the backfill level.

Sprinkle the tank with a mixture of cement and sand, and the last 30 cm with soil. After that, the system is ready for start-up and operation.

Septic tank maintenance: price

Plastic tanks do not require special care.

1. Once a quarter, VOC conducts an assessment sludge. If it is dark and begins to thicken, then it must be removed. To do this, you can use a simple drainage pump.
2. Once every 1-2 years, it is necessary to pump out the sediment from the sump using a sewage machine. At this time, it is recommended to flush the entire tank.
3. Once a week it is worth looking into the hatch of the tank to evaluate the work. This is especially true for aerobic installations.

You can conclude an agreement with a specialized organization for maintenance. A one-time procedure with sludge pumping and equipment revision costs at least 4,000 rubles. The minimum cost of annual maintenance is 15 thousand rubles.

The full range of works and the price for them depends on the model.

*for VOCs, the volumes of salvo release are indicated.

Installation cost

If you decide to install a septic tank inexpensively, i.e. independently and chose ready-made plastic model, then the cost finished building will depend on the price of the model, sand, cement and pipelines.

You can order the installation of a turnkey cleaning system. The minimum cost of such a service is 21 thousand rubles.

But having invested once, you will ensure the reliable operation of the treatment equipment and the cleanliness of the site itself.

It is enough to look at any catalog of an online store that offers septic tanks for a country house or a summer residence, and you have to deal with challenging task choice. In fact, along with dealers in this area, there are enterprises that have only recently entered the market, or successful manufacturers that have been working for a long time and have won success, but decided to develop a new direction of their activity. Therefore, we suggest that you familiarize yourself with what septic tanks are for summer cottages and compare them so that you decide which one is better.

Septic tanks for summer cottages: which one is better? What to consider when choosing them?

The model range of septic tanks is quite wide, which allows you to choose the best septic tank for giving, which will meet individual requirements. When choosing such a cleaning system for a country house, cottage or cottage, you need to consider the following factors:

• The number of permanent residents (consider possible guests).
• The number of sanitary points (showers, toilets, jacuzzis, bathtubs, sinks) and household appliances (dishwashers and washing machines), the volume of their effluents.
• Groundwater depth.
• Soil type on the site.
• Discharge option for treated water (gravity or forced).

How is the installation of a septic tank in the country:

• Pit preparation.

• Arrangement of supply trenches for pipes and wires.

• Installing a septic tank in the pit and sanding around.

• Filling the chambers of the septic tank with water.

• The pipe crashes, the power supply is connected.

• Start-up and adjustment works are being carried out.

• The outer part of the septic tank is being prepared, taking into account the features landscape design within the territory of.

The principle of operation of septic tanks

A septic tank is a facility that is used to treat sewage. The scheme of its device implies the presence multi-chamber system. Wastewater enters the first tank (sump) through a pipeline from the house. Bacterial decomposition of sewage takes place in it. In some devices, usually industrial production, facilities are installed here that are responsible for filtering polluted water.

The decomposition of wastewater occurs under the influence of anaerobic or anoxic bacteria. They convert the liquid entering the sump into clarified water, gas and mineral insoluble sludge or sediment.

The formed gas as a result of the decomposition of wastewater is discharged through ventilation pipe, and the water goes into the overflow hole in the second tank. In this case, anaerobic bacteria do not stop cleaning the drains. Further, the clarified water enters the next tank or is fed to the filtration fields. After soil filtration, the liquid is absorbed into the soil. This structure belongs to anaerobic type systems or non-volatile septic tanks.

There is also a variety of devices that require electricity to operate. These are aerobic septic tanks with biological treatment. In such devices, wastewater treatment is carried out by aerobic microorganisms that simply cannot exist without oxygen. For this reason, the compressor automatically turns on after certain time, supplies air into the tanks. The process of decomposition of wastewater in these plants is very fast. The level of purification of polluted waters is 98%.

The principle of operation of an aerobic septic tank requires a constant flow of oxygen, since the bacteria contained in the activated sludge die and the cleaning stops.

One of the most common structures is a storage septic tank. It is a single-chamber hermetic device used to accumulate wastewater, as a result of which it is pumped out using a sewage truck. Additionally, the tank is equipped with a filling level sensor. This option is the best for those who often appear in a country house, but various reasons cannot be arranged effective plot wastewater treatment.

Septic tanks for summer cottages: which one is better?

1. Energy independent septic tanks.

Models that work without electricity and are not tied to the presence of electrical networks are suitable for small country houses. In a remote area and garden partnerships, there is a possibility of a power outage for a sufficiently long period, so you should decide in advance on the equipment for small country houses. In remote areas and garden partnerships, there is a risk of power failure for a sufficiently long period, so it is worth choosing equipment for sewage in advance.

Of course, users have a question whether a septic tank is needed at all in the country, if it is possible to equip a cesspool. We will not convince the owners of dachas, but simply remind them of aesthetics, sanitary requirements and basic amenities. We offer you to get acquainted with the best non-volatile septic tanks.

• "Tank".

Septic tank "Tank" is made of high-strength plastic having a thickness of 10 to 17 mm with stiffeners. The design itself provides resistance high loads, which are formed under ground pressure in summer and winter. The estimated service life of the product is at least five to ten years, subject to the operating conditions. A conventional septic tank works on the principle of wastewater treatment by settling or further biological decomposition of the material with a high-performance biofilter. The infiltrator is responsible for the distribution of purified water that enters the ground.

The unique shape of the body protects the design of the septic tank from being squeezed out by the soil, and the possibility of equipping it with a high neck allows you to place them at the required depth. A special design, including block modules, allows you to collect almost any volume of a septic tank, and overflow pipes act as connections.

The operating conditions of a septic tank imply its periodic cleaning of accumulated solid residue. With proper operation of the equipment and the use of bacterial colonies, the tank is cleaned every four to five years. But it is recommended to do this at least once a year. In the case of periodic use of a septic tank, for the winter, when it is not supposed to clean sewage for sewage, approximately a third of the water is removed from the tank.

The price of a septic tank "Tank"

It is worth noting that the price of this septic tank is more than affordable for many owners of private housing. This is one of the main advantages that causes a huge interest in the products. The price largely depends on its volume and therefore increases with the increase in capacity.

Reviews about the septic tank "Tank" for giving

Alexander

“The septic tank filters perfectly, there are no comments. There were no problems with its installation, since everything is described in detail in the instructions. Convenient, environmentally friendly, economical. I leave positive feedback».

“I studied a lot of reviews, customer opinions differ, but, as a rule, negative emotions arise only due to improper installation and operation of this septic tank.”

“The septic tank does not consume electricity and operates completely autonomously, but I would not take a very large volume, since unfavourable conditions for the development of bacteria.

“Two years ago we installed a Tank-1 septic tank, from which we use water to irrigate the garden. It is very convenient, since there is no source of water on our site, including a technical one.”

• "Triton".

Three chambers that are responsible for the implementation of the process of removing various suspensions from polluted water, anaerobic decomposition biological material, as well as the supply of treated wastewater to a special filtration site. This septic tank is produced in several versions, which makes it possible to choose between models with a volume of 2 to 40 m 3.

Once a year, or in case of intensive use twice a year, it is worth cleaning the container of accumulated solid sediment. Lifetime plastic container- Approximately 50 years. When installing equipment, it is necessary to provide an "anchor", a monolithic concrete surface or a concrete slab that provides good retention of the septic tank at the required level.

For small baths and country houses, it is better to use the Triton-mini models, which are compact septic tanks for the summer, designed to receive wastewater of small volumes.

Despite the low cost, treatment plants are popular both for small summer cottages and for country cottages for permanent residence. The septic tank provides the necessary level of wastewater treatment.

“The summer before last, I installed a Triton N-1 septic tank at my dacha. Works perfectly, fully copes with the declared function.

“Easy installation, low cost, simple maintenance. The quality and cost are fully justified. My parents installed this septic tank last summer and were very pleased. The first cleaning went quickly, without unpleasant odors.”

“I installed this septic tank for my parents at the dacha in the village. Used for three years, father is happy. A great option for giving, where there is a small amount of drain water.

“When properly installed, with a Triton septic tank, neither severe frosts nor other typical problems are terrible. Two years have passed since the installation of the septic tank, everyone is happy. The guests who came to our dacha also seriously thought about installing such a septic tank.”

• "Aqua-bio".

The septic tank is intended for a summer cottage, where you can create a filtration field or another type of soil purification of water discharged from the tank. A simple septic tank system consists of passing contaminated water through 5 chambers. Initially, solid suspensions are deposited in 3 compartments of the tank, then in the remaining 2 chambers, processes of anaerobic decomposition of organic matter occur due to the development of anaerobic colonies on the surface of a special load.

The main advantages of this septic tank are a large number of chambers, which increases the efficiency of wastewater treatment. As a result, you will not need to reconstruct the filtration fields, which will be clean for a long time, which means you will not face additional costs during the operation of the septic tank. The tightness of the durable plastic housing eliminates the possibility of contaminated wastewater entering the soil.

The performance of different models can vary in the range from 600 to 1300 liters per day. It is from this indicator that the price of a septic tank for a summer residence depends. A simple calculation allows you to decide on the most suitable model, but do not forget that such a septic tank is not suitable for an area where there is a high level of groundwater.

Models of the septic tank "Aqua-bio" differ from each other in performance and volume. Today containers are produced with a volume of: 3600, 3000, 2500, 2000 liters. Accordingly, with the productivity of l / day: 1300, 1100, 900, 700.

Prices for the septic tank "Aqua-bio"

If we talk about the cost of the Aqua septic tank, then, in comparison with similar solutions, such facilities cannot be classified as budget ones. You can verify this by carefully studying the table below.

Reviews about the septic tank "Aqua-bio"

“Not disappointed, works reliably and stably. In severe frost, once "grabbed" with ice by three centimeters. I had to resort to insulating covers.

“I ordered, completed the installation and have been operating for several years now. Everything is fine, I can say with confidence that he is not afraid of even severe frosts.

“I did a thorough installation, we wintered well, I leave a positive review and recommend this septic tank for a summer residence.”

1. Energy dependent septic tanks.

They need a constant connection to electricity, they can work on the principle of forced oxygen supply to the batteries, namely aerobic wastewater treatment. Such septic tank models are a real deep cleaning station that allows you to bring to required level when the drain can be directed to storm sewer, reservoirs and ditches without any risk of disturbing the ecological balance. Among domestic septic tanks, it is worth highlighting the five most common models.

• "Tver".

Such a septic tank belongs to local treatment facilities, where wastewater treatment takes place in a complex manner. The device uses several different technologies at the same time, which are combined into single system and provide excellent results when used small area land plot.

It should be noted right away that such a solution is volatile and adapted for use in houses intended for permanent residence. But it is also great for giving, if they are respected simple rules conservation.

The equipment contains a multi-chamber container and high-quality plastic. The first chamber acts as a sump that holds most of the sparingly soluble inclusions. Some of them will sink to the bottom, while the rest will float on the surface. Anaerobic decomposition processes take place here, continuing in the second chamber on biofilters. Then comes the chamber-aerotank, where the water is saturated with oxygen. This activates aerobic water purification by microorganisms. The liquid is further purified in several chambers, where it flows by gravity. In one of them there is a limestone load, where it is associated with harmful decomposition products, namely nitrogen and phosphorus compounds.

The addition of chlorine-containing reagents can increase the efficiency of water disinfection.

Models are installed on different types soil, even if the dacha is located on former peat mines, which are characterized by increased aggressive environment. Durable plastic does not corrode, and an additional “anchor” pre-installed in the pit will not allow the tank to “float”.

home distinguishing feature septic tank "Tver" - receiving a large volume of wastewater. Therefore, if you need to drain the bath, then he will cope with this task without deteriorating the quality of the water at the outlet and without the release of untreated effluents.

Reviews and price of the septic tank "Tver"

If you look at all the reviews about this product, you can come to the same conclusion: in most cases, such a treatment plant fully satisfies the needs of every modern person. There were no complaints about difficulty during operation or cleaning. One cannot but rejoice that this septic tank is a development of our specialists. At the same time, the price for it is affordable, as you can see by examining the information in our table.

• "Leader".

Such septic tanks use electricity to remove sediment from the septic tanks and to run an aerator that saturates the water with oxygen for the development of aerobic microorganisms that eat organic matter. As you can see, this is a volatile solution. Thanks to integrated approach and the presence of six chambers, the process requires the use of special biological additives, and the system is highly resistant to temporary overloads due to wastewater pollution.

Wastewater treatment is carried out according to the principle that the discharge can be carried out in a convenient place: ditches, a reservoir or a drain well. As you can see, there are no violations of the norms for the discharge of pollutants, full consistency with the ecology of the surrounding nature.

Local wastewater treatment occurs according to the principle of passing through all the stages of the tank with pumping out the activated sludge that has accumulated. The first chamber is used for the mechanical stage of purification - primary water clarification and sedimentation of suspended particles. The manufacturer indicates that the efficiency of this chamber is 2/3 of mineral contamination.

As for the second stage, a bioreactor is used here, in which anaerobic bacteria initiate fermentation (the conversion of substances that are difficult to oxidize into simple ones for the oxidation process). Moreover, bacteria develop on a polymer fishing line that imitates algae. In the subsequent blocks of the septic tank, namely in the third, fourth and fifth, wastewater is purified by aerobic bacteria. For them, all the conditions for life are provided, which are created with the help of two aerotanks with aerators.

The bacteria themselves multiply on the porous material, form entire colonies, turning into activated sludge. As a result of the victorious battle with drains, the last stage of the septic tank emerges. Here, phosphates are neutralized in an alkaline environment.

The price of a septic tank Leader

The cost of a septic tank with a turnkey installation directly depends on its dimensions, power, weight, as well as connection to the sewer. Also, septic tanks differ in price, which depends on the chosen model of the cleaning device.

Nowadays, the price of a Leader septic tank may differ, so below we will understand not only the price category, but also different models septic tank.

• "Poplar".

The design of this septic tank allows it to be used in the following temperature range - from -30 to +40 0С. It works on the principle of sewer water passing through four compartments (aerators are installed in two of them). Regular supply of oxygen to the contents has a positive effect on the development of bacteria that are responsible for the decomposition of the biomaterial. The necessary oxygen pressure is provided by compressors, and the process of fluid circulation between different compartments is carried out by airlifts.

When human waste is decomposed by bacteria, the wastewater enters the sump, where activated sludge is deposited, and the liquid is sent through the filter to the collection system. All pumps are located in a sealed compartment, as a result of which the ingress of moisture on the contacts is completely excluded and ensured reliable protection equipment.

The body of the septic tank is made of polymers that do not corrode, and average term A septic tank is approximately 50 years old. As for deposits, they are removed independently or with the help of a sewage machine.

Septic tank "Poplar": reviews and prices

If a installation work are carried out in strict accordance with all requirements, then there will be no questions during the operation of the Topol septic tank. We got acquainted with the numerous reviews on the operation of this treatment plant, which we could find on the Internet, and came to the following conclusion: the reviews are mostly positive, without harsh criticism of the septic tank and its characteristics. The main thing is to choose the installation that is appropriate in terms of performance and carry out its correct installation.

If we talk about prices, they are competitive, not cheaper and not more expensive than other options. Of course, they grow as the capacity and capacity increase. In the table below, you will be able to get acquainted with the average cost of the Topol installation of various capacities.

• "Topas".

In the Topas septic tank, sewage water is cleaned in several directions: the process of decomposition of organic materials, the reduction of wastewater salinity, as well as the removal of mechanical impurities. The principle of operation of such a septic tank cannot be considered innovative, but be that as it may, it provides purified water (98%) that you can use for irrigation.

The first stage of cleaning is carried out in the receiving stone, in which precipitation takes place. mechanical impurities. Then the airlift pumps partially purified water into the aeration tank to resolve organic compounds as a result of the vital activity of bacteria (their colonies are in activated sludge). Silt suspensions coming with water have more deep cleaning, which is deposited in the next compartment. The fully purified water will then be removed from the system and the sludge returned for later use.

Service maintenance of equipment occurs when checking the operation of the compressor and diagnosing a septic tank.
