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

It allows you to save the area from pollution, and in some cases makes it possible to obtain industrial water from wastewater for watering plants, washing cars, etc.

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

Whatever it is cleaning device, its work is based on 3 principles:

• sedimentation of large suspended matter;
• floating of light pollutants;
• biological decomposition.

All septic tanks consist of several chambers. The first 2 stages of purification take place in the first tank. The pipe leading to the next chamber is located in the center, draining water that no longer contains floating suspended matter and heavy fractions. The type of biological decomposition and its effectiveness depends on the type of apparatus.

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

Types of septic tanks for a private home

The basis for dividing wastewater treatment systems into types is the dependence on electricity, the type of biological decomposition and the material from which the septic tank is made.

Anaerobic and aerobic varieties

In more simple designs in the second and subsequent tanks, anaerobic (oxygen-free) decomposition of contaminants occurs. 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 filter bed, on which an additional film of microorganisms is formed that continue the bio-oxidation process.

Local treatment plants more complex and efficient designs. They simulate large sewer waste treatment systems.

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

After this, the water enters a special settling tank to sediment 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. The settled dense sludge must be periodically removed from the tank.

There are also storage tanks in which the water does not undergo any treatment other than sedimentation. They only collect wastewater and periodically remove it. Storage tanks can only conditionally be called a septic tank, this cesspool– cheap to install option, suitable only for small country houses with low waste volume.

Electricity dependence

This principle of classifying wastewater disposal systems is important to know, 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 takes place, and water is transferred between reservoirs and to the soil purification stage 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 rely on electrical power where terrain conditions require a pump to be installed to transfer fluid to the soil filtration stage.

What and how to make a septic tank from?

Containers for treating wastewater can be made from different materials.

1. Eat ready-made plastic tanks. You can make them yourself from several plastic pipes large diameter or Eurocubes. Installing such containers is quick and easy, without the use of special equipment. They are durable and have become the most popular recently.
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 great depths. It is recommended to treat the inside of the container with an anti-corrosion compound to extend its service life.
3. Brick- budget, but physically expensive material. Bricks are laid on concrete base. The cross-section can be round or 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 freight transport and crane. Concrete containers often leak at the joints.

Budget-friendly, but not very reliable, are tanks made of wood or truck tires.

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

An important factor is the price of the finished station.

How to choose a septic tank for a private home?

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

Performance

The required power and volume are determined by the number of inhabitants. If guests will periodically live in the house, then they also need to be taken into account when calculating. On average, one person produces 200 liters of wastewater per day.

For a family of four, equipment with a capacity of 800 liters is required. Because wastewater can remain in tanks for 3 days, then the resulting power must be multiplied by 3 to get the volume value. For our example we need tank with a volume of 2.4 m3.

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 container must be below the zero point. There are special ready-made models with an elongated neck and a low inlet.
2. Self It is recommended to install the equipment where there is elevation to protect from atmospheric moisture.
3. If the landscape does not allow drainage from the reservoir by gravity, then you need to choose a model with forced evacuation of purified liquid, in the last chamber of which a pump is located.
4. For clay soils prone to expansion when freezing We need structures with especially strong walls: concrete, plastic with stiffeners.
5. For soil purification, it is especially important to know the type of soil. Most best option – sandy soils. In other cases, arranging filtration fields requires a lot of effort.

Cost and popular models

Photo – Tank 2.5

Each owner takes into account the price of a waste disposal device. But it’s better not to save money here.

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 treatment Tank 2.5 fully equipped from 36 thousand rubles.
2. Proven Topol 5, related to complete biological treatment stations, can be purchased minimum for 72,000 rubles.
3. Topas 5 also provides a high degree of wastewater treatment. What is the cost of such equipment? about 80,000 rubles.
4. If you are looking for a septic tank for your dacha, then a good option might be "Triton-mini", volume 750 l. Together with a soil filtration system it costs about 22 thousand rubles.
5. More positive feedback dials and VOC "Unilos Astra-5". You can become the owner of this system for about 80 thousand rubles.

Many users have already been convinced of the reliable operation of these devices. In addition, they are all simple and easy to install yourself.

Construction and installation of septic tanks

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

1. From the foundation at home there must be at least 5 meters to the septic tank. But you don’t need to install it very far either, otherwise you will need an inspection well.
2. Distance between trees and a septic tank 3 m.
3. From rivers and reservoirs there should be 30 m to the waste treatment device, and 50 m from wells and wells.
4. No roads should 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 this data, a septic tank is installed in accordance with with step-by-step instructions.

1. They dig trenches at a slope for pipes and a foundation pit for the septic tank itself.
2. A 10 mm thick layer of sand is poured into the ravines and compacted, making sure to maintain the slope.
3. Construct a sand and, if necessary, concrete pad in the pit. It should be smooth.
4. The septic tank is leveled.
5. It is connected to supply pipes, as well as a pipeline leading to soil filtration or a collection tank.
6. The pipes and tank are filled up. It is important to pour liquid inside 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 this, the system is ready for startup and operation.

Septic tank maintenance: price

Plastic tanks do not require special care.

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

You can enter into a service agreement with a specialized organization. A one-time procedure with pumping out sludge and inspecting equipment costs at least 4,000 rubles. The minimum cost of annual maintenance is 15 thousand rubles.

The full range of works and their price depend on the model.

Installation cost

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

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

But once you invest, you will ensure reliable operation cleaning equipment and cleanliness of the site itself.

Installation of a septic tank – practical way solving the problem of wastewater disposal during the construction of a local sewerage system. But, you must admit, it is sometimes not easy to make a choice among the variety of ready-made designs.

To simplify the task, we suggest that you familiarize yourself with an overview of the main types of treatment facilities and popular models from leading manufacturers. We will tell you which septic tank to choose based on the characteristics of its operation, and outline the main parameters of the device that must be taken into account when purchasing.

For a better understanding of the issue, we have supplemented the information with photographs of various models of waste disposal units, as well as diagrams for their installation.

A septic tank is a waterproof structure consisting of one or more sections or divided into two or three compartments or chambers. But any sewage treatment plant has its own characteristics.

Therefore, in order to choose a recycler wisely, it is necessary to analyze the types of equipment on the market, understand the principle of their operation and determine for yourself the feasibility of using a particular model.

Types of materials used

Septic tanks, which are the main element of local sewerage, are classified according to different criteria.

How to choose a septic tank for a private house.

Each septic tank for a private home must effectively fulfill the most main function– make wastewater safe for residents of the house and surrounding area. At the same time, such an installation also helps to significantly save on utility bills.

Before choosing the most suitable and efficient septic tank for a private home, some factors must be taken into account:

The number of people living in the house.

The volume of wastewater entering the system and the number of sources requiring maintenance (sinks, toilets, showers, bathtubs, washing machines, dishwashers).

The material from which the septic tank for a private home is made.

Features of the soil on the site and the terrain.

The presence of a nearby reservoir where excess water can be removed.

Septic tank performance.

If you choose a modern, highly efficient septic tank for a private home, then the best option would be concrete look cleaning station. Such a septic tank is not subject to temperature changes and is resistant to soil pressure. Concrete septic tank for a private home, you can do it yourself or by contacting a professional company with experienced specialists. It is a structure made of concrete rings that are connected to each other by reinforcement. Such a system is suitable for organizing storage or settling local sewerage, and will good choice for a house where people permanently live.

An excellent option would be to buy a septic tank for a private house made of plastic. These are ready-made structures in the form of plastic containers, which are excellent for any type of soil, have a long service life and are easy to maintain. Treatment stations provide a deeper degree of purification than concrete structures, but the price of a septic tank for a private house of this type will be higher.

Today, a fully autonomous septic tank for a private home is the most popular option. It uses forced multi-stage filtration, which ultimately purifies the water up to 95-98%. The combined cleaning method (biological and mechanical) guarantees safety for the environment and the health of people living in the house.

It is best to buy a septic tank for a private home from a company that officially cooperates with the manufacturer and offers a full range of services for installing a treatment station, launching and service. Professional company provides a guarantee for all work performed and installs equipment in accordance with all rules of SNiP and sanitary epidemiology.

Pumping septic tank for a private house.

If you decide to install a pump-out septic tank for a private home, then be prepared for the fact that it needs to be cleaned regularly. You can do this yourself or with the help of specialized companies.

1. Manual cleaning requires a lot of time and effort, and will require solving the problem of waste disposal.

2. Mechanical pumping involves the use of special powerful pumps and equipment for waste removal. A septic tank for a private home also requires complete cleaning of the pipeline, dilution of activated sludge, and disinfection. All these services are not cheap, but they compensate for the cost of time and nerves and guarantee high quality cleaning of the system.

3. An automatic septic tank for a private house, the price of which is higher than the cost of a concrete one, can be equipped with a pumping function. It is equipped with filters that self-clean several times a month. However, here it is necessary to monitor the number of bacteria, since they are washed off along with the liquid into the sewer.

There is no universal answer to the question - which septic tank is better for a private home. For each individual case, it is necessary to select the optimal model option and take into account the number of residents, volumes of wastewater, soil characteristics and climate in the area. Domestic producers Septic tanks offer a wide range of models that vary in performance, design and cost. Therefore, before you buy a septic tank for a private home, you should consult with experienced specialists.

If you are looking for an effective septic tank for a private home, the price of which is affordable, then here is a rating of the best options:

Treatment plant Topol.

Cleaning system Topas.

Autonomous station Termit.

Septic tank for a private house Ecoline.

The list goes on because Russian manufacturers regularly improve their products and offer new high-quality products to the market.

Installation of a septic tank for a private house.

A septic tank for a private house should be located no closer than 5 meters from a residential building. At the same time, to the source drinking water must be at least 30 meters. When installing a septic tank for a private home, the price of which is affordable, it is worth remembering that the further it is from the house, the more it will be required sewer pipes and the higher the final cost of the work will be. To install a septic tank for a private home you need special tools and equipment, sand and cement, insulation for pipes. The process itself consists of 4 main stages:

1. A pit is dug for the septic tank and ditches for the pipeline.

2. The septic tank is placed in the pit using technology.

3. A pipeline with a slope of 1-2 cm per 1 is mounted and connected linear meter pipes.

4. The entire structure is filled with a mixture of sand and cement 5:1 and compacted.

Thus, you can install a septic tank for a private house yourself, but it is better to entrust this difficult work professionals to ensure a perfectly functioning wastewater treatment system.

Content

To save yourself from the need to inhale odors from cesspools, it makes sense to buy a septic tank for a private home, having first studied its features and given preference to a specific variety. The device will save the residents of the house from any troubles. For permanent residence large quantity people on the territory of a private house, the drainage pit simply cannot cope with the task and it will need an assistant, which can be a septic tank.

What is a septic tank

Private houses or country cottages differ from ordinary apartments the fact that there is no central sewerage system and the use of a special device will be required to remove domestic water. A septic tank is a sealed container in which liquid waste accumulates. Some models have a biological treatment function, but they cannot be classified as full-fledged treatment facilities.

What is it needed for

Owners country houses when installing sewerage systems, they must ensure wastewater treatment, taking into account sanitary standards and soil characteristics. A reliable option would be a septic tank, also called a septic tank, whose function is to accumulate and purify waste leaving the premises. It passes impurities through itself, not allowing it to penetrate into the soil. Before making a septic tank in a private home, it is worth understanding its structure and operation.

Device

When building a cottage, it is necessary to pay Special attention arrangement autonomous sewerage, since there is no central one for the project. Installing a septic tank in a private home allows you to solve problems with the removal of household waste and its cleaning. The work is carried out in three stages:

• Sewage drains leaving a private house are collected in sealed plastic containers local treatment plant.
• Inside the septic tank, particles are separated into heavy and light. The former settle at the bottom of the well, and the latter enter the next compartment.
• Aerobic cleaning is not always possible, so anaerobic cleaning often occurs. The sewage is filtered, and the resulting methane is removed through the exhaust pipe.

Types of septic tanks for a private home

Local treatment facilities are divided into two large groups - old and new. The first group is represented by brick septic tanks and reinforced concrete structures. These types are used less frequently for private homes due to time, power and material costs. However, concrete structures are considered more durable. New ones include ready-made plastic septic tanks for the home, having several more subspecies. The undoubted advantages include low cost, practicality of plastic, and lightness of the product.

Cumulative

Manufacturers of septic tanks installed in private homes understand that without sewer system You can’t get by, so they offer a wide selection. The use of special tanks is often a solution to the problem. A storage septic tank is a container into which domestic water flows through pipes and is pumped out as it fills. You need to make calculations of the volume of liquid yourself and, based on this, order a storage tank the right size. This option has a number of features:

• No installation required drainage wells, which has a positive effect on the cost of the system.
• The tank itself for a private home will not be cheap, despite the simplicity of the device.
• The owner of the house can independently decide where the septic tank will be installed. However, you need to think through everything so that the access of the sewer truck is unhindered.
• The cost of pumping out waste will be expensive, so if your household water accumulates quickly, then a storage single-chamber septic tank is not your option!
  

  Bioseptic

  It is impossible to ensure a comfortable life for permanent residence in a private house without sewerage. A bioseptic with the help of special bacteria solves the problem of wastewater treatment, giving a kind of guarantee of soil safety. The process looks like this:

  1. Sewage enters the first chamber popular septic tank, undergoing primary purification there. Large particles and fats are separated and settle at the bottom.
  2. Waste is sent to the second tank three-chamber septic tank, where cleaning continues more actively.
  3. The sludge enters the first chamber, and the treated wastewater enters the third, where the final and main stage occurs.
  4. Completely purified water enters the well through a secondary settling tank.

  

  With post-treatment

  Waste that passes through a septic tank cannot be completely counted clean water, which can be discharged into a body of water or soil. Sometimes it is impossible to do without soil purification. The design of a treatment plant for a private home depends on various parameters: the characteristics of wastewater and soil. Soil filtration is more expensive, since it will be necessary to install:

  • absorption trench;
  • sand and gravel filter;
  • filter well;
  • filter fields.

  

  Septic tanks for home

  It is not easy to make a choice from the assortment available for sale. Initially, the eye falls on those devices that are cheap:

  • Name: KNS Unipump Sanivort.
  • Price: 11,328 rubles.
  • Characteristics: the device pumps out wastewater, accumulating it in a tank.
  • Pros: low price.
  • Cons: small capacity.

  

  More serious septic tanks installed in private homes are many times more expensive. However, they are often worth it:

  • Name: EcoProm Rostock.
  • Price: 55900 rubles.
  • Characteristics: design containing a biological filter for wastewater treatment.
  • Pros: high degree cleaning.
  • Cons: large dimensions.

  

  There are entire autonomous deep biological treatment stations. In a private home they would be appropriate:

  • Name: Unilos Astra 3.
  • Price: 66,300 rubles.
  • Characteristics: a container for collecting and filtering sewage that occurs in several stages.
  • Pros: easy to use, copes well with the tasks.
  • Cons: none.

  

  Price for installing a septic tank

  Retail and online stores are full of sales, promotions and discounts. Before installing a septic tank for filtering waste in a private home, you need to purchase it. It is not recommended to order delivery by mail; it is better to use the services transport company. You can buy a septic tank for your home, depending on its type, at a price from 12,000 to 70,000 rubles. However, purchasing is half the battle. Installation costs may vary:

  How to choose a septic tank for a private home

  The market for devices for organizing sewerage in a private home is wide and offers devices for every taste. Regions are not lagging behind big cities such as Moscow and St. Petersburg. However, it is necessary to approach the choice of materials responsibly in order to avoid problems in the future. It is necessary to initially calculate the volume of waste and the location for installing the structure. Which septic tank to choose for a private home will depend on the length of stay:

  • If your goal is to move to a private home on a permanent basis, then it is better to opt for bioseptics. This will ensure better wastewater treatment.
  • Those who come to a private house for the weekend or for the summer can limit themselves to a storage septic tank. The design is simple, does not require electricity, but requires periodic emptying of the tanks.

Building Vacation home or a dacha, everyone strives to make them as comfortable as possible. Therefore, suburban housing is equipped with sanitary and household appliances which must be connected to the sewer. But wastewater must be discharged somewhere, provided that, as a rule, there is no central sewerage system outside the city. Therefore, the question of which septic tank is better for a summer house or private cottage is relevant.

Holidays outside the city attract many people. However, the lack of necessary amenities can greatly overshadow suburban life. Indeed, few people will like the need to wash in a basin and visit the toilet located at the far end of the site.

In order not to sacrifice comfort, many people undertake to equip country houses and dachas local systems sewerage. And at the same time there is a need to choose and install a septic tank - which one would be better suited in each specific case? Every developer must resolve this issue in advance.

Selection by operating principle

First of all, let's figure out what septic tanks are based on the type of work. In principle, three types of treatment plants are used today:

• Storage;
• Settling tanks with anaerobic biological treatment;
• Deep cleaning systems based on aerobic processes.

Drives

If you are choosing equipment for a small country house in which you do not plan to live permanently, then the storage septic tank will be the most practical option. Such installations do not process wastewater, but only accumulate it. As the container accumulates, it is cleaned using sewer equipment. Advantages of the option:

• Cheap and easy to install;
• Complete environmental safety.

Disadvantages of this solution:

• The need to pump out waste as the tank fills;
• Presence unpleasant odor at the time of pumping.

Advice! A storage tank is a good option for a septic tank for a summer residence with low water consumption. If people do not live in the house permanently, and water is used sparingly, then pumping will have to be carried out once a month or even once for the entire summer season(the frequency of pumping also depends on the volume of the storage tank).

Sedimentation tanks with anaerobic type of wastewater treatment

When considering the types of septic tanks, it should be noted that settling tanks with anaerobic treatment processes are a practical option for arranging a local sewage system for a private cottage. In such septic tanks, two types of natural cleaning are used:

• Mechanical settling, which makes it possible to separate undissolved inclusions that have a density different from water;
• Anaerobic biological decomposition of organic matter produced under the influence of microorganisms.

In such septic tanks, only primary clarification of water occurs; it is purified by approximately 60%. Therefore, it is necessary to build installations for soil purification - aeration fields, filtration trenches and wells. The advantages of this option:

• Ease of use. A septic tank that is put into operation does not require constant attention;
• Low operating costs. Maintenance and pumping of sediment from the septic tank is carried out no more than once a year;
• Multiple options. Ready-to-install models available industrial production, or you can build septic tank chambers yourself, for example, from reinforced concrete rings;
• Full autonomy. Septic tanks do not require power supply.

Advice! The question may arise, which is better - reinforced concrete rings for self-assembly chambers or a ready-made septic tank? Here the choice depends on the budget allocated for the construction of the sewerage system and the planned labor costs. If your budget allows, then it is easier to order the installation of a ready-made septic tank. The option of self-construction will be cheaper, but will require more labor.

Disadvantages of septic tanks:

• The operation of a septic tank of this type greatly depends on geological conditions - the ability of the soil to absorb water, the level to which soil water rises. For example, if groundwater on a private property plot rises high, the likelihood of flooding of the septic tank increases when its chambers are not airtight enough (lined with bricks or made of rings). And if on the site clay soil, additional difficulties arise with the arrangement of soil post-treatment.

Aerobic cleaning systems

Choosing the best option septic tank for a private cottage, many opt for modern local stations bioremediation. In such stations a full cycle of water processing is carried out.

At the exit from the installation it turns out technically pure water, which can be dumped into a ditch or sent to a storage well for further use for economic purposes (watering, washing paths, etc.). The advantages of this option:

• High purification efficiency, which makes it possible to avoid the construction of soil treatment plants;
• No smell or noise during operation;
• Possibility of installation under any geological conditions.

• High cost of stations;
• The need to connect power supply;
• Higher chance of failure. In simple settling tanks there are simply no parts that could break, and biorefinery stations are equipped with compressors, airlifts, and automation systems, so they are more likely to fail.

Selection by performance

Even the best septic tank option for a private home will not work effectively if the installation capacity is chosen incorrectly. The performance and volume of the septic tank chambers depend on the water consumption in the house. The more equipment in the house connected to the sewer and the people who use it, the more productive the model is needed for the construction of the sewer.

If a ready-made model is purchased, then the passport, as a rule, indicates how many people the model is designed to serve. During construction homemade installations You'll have to do a simple calculation.

It is necessary that the wastewater remains in the septic tank for at least three days, otherwise the liquid will not have time to settle well and the quality of cleaning will decrease. Thus, it is necessary to select the volume of the sump chambers so that they can accommodate the amount of waste generated in the house over three days.

It is not difficult to calculate three-day water consumption. If the house has a standard set of plumbing (as in a city apartment), then for each person living there is approximately 200 liters of water per day and, accordingly, 600 liters in three days.

Advice! If a bathhouse with a swimming pool is being built in the house, or it is planned to install several Jacuzzis, then the water consumption will naturally be greater.

To determine the volume of the chambers, it is enough to multiply the number of people living in the house by 600 and add 10-15% of the reserve for unforeseen cases such as the arrival of guests.

Selection of septic tank material

If you plan to purchase a ready-made septic tank, then its body will most likely be made of polypropylene or other polymer material. When constructing cameras yourself, variations are possible. Let's look at homemade septic tanks - what are the options for materials for construction:

• Metal containers. This is the most impractical option. The fact is that the metal is quickly destroyed by wastewater, and the installation becomes unusable;
• Concrete structures. When choosing this option, two solutions are possible - building a prefabricated structure from rings or constructing a monolithic septic tank. The first option is easier to implement if lifting equipment is used, but is not airtight enough. With highly located soil waters, such a septic tank is very unreliable. Monolithic structures completely sealed, but their construction requires time and serious labor;

Advice! To extend service life metal container, it is necessary to treat it inside and outside with anti-corrosion compounds. However, even in this case, the installation will last no longer than 5-6 years.

• Fiberglass and plastic. These materials are best suited for constructing a septic tank. They are durable and lightweight, do not corrode, so they last a long time. For self-construction For a septic tank, you will need to purchase ready-made containers of the required volume, for example, Eurocubes are often used.

Choice by cost

• Almost free septic tanks. These are structures built independently from scrap materials, for example, old tires or plastic barrels. This option may be suitable for small country houses, in which water consumption is minimal or for baths. Such septic tanks have low productivity, and when constructing chambers from tires, they also have insufficient tightness;
• Cheap septic tanks. These are installations made of brick or reinforced concrete. Low-capacity industrial production plants are also relatively inexpensive;
• Septic tanks manufactured by industry with a capacity of more than a cubic meter of wastewater per day have an average price;
• The most expensive systems are complete biotreatment systems.

So, when choosing treatment plant it is necessary to take into account local conditions: water consumption, geological conditions, financial capabilities of the owners. They will help you decide which septic tank is best for country house reviews from installation owners who, through their own experience, have found out all the disadvantages and advantages of the models used.
