Which septic tank is better for a country house. How to choose a septic tank for a country house - an overview of options

How to choose a septic tank for a private house

In the absence of the possibility of connecting to a centralized sewerage line, the owners of country houses have to take care of arranging local wastewater treatment systems. Septic tanks can help with this without affecting the environment. There are many types of such devices. Therefore, those who decide to install a local sewage system in their area have a question about which device is better to choose.

Types of septic tanks

The main classification of systems for the disposal of wastewater from a private house is based on the principle of operation.

    Storage tanks are the easiest option. They are sealed containers. In these containers, sewage enters and accumulates there, which must be pumped out, periodically calling a sewage truck.

Note! It is necessary to choose a place on the site for the placement of septic tanks that carry out aerobic or anaerobic wastewater treatment, taking into account sanitary rules.

There are ready-made versions of various companies on the market, but with certain skills, you can make them yourself, for example, from concrete rings. The material, along with the design and other important parameters, is one of the factors that are taken into account when choosing a septic tank.

What should be considered when choosing a waste disposal device?

Before buying a septic tank, you need to answer a few questions.

  1. How many people will live in the house, what sanitary equipment will be installed? These factors determine the performance and volume of the septic tank.
  2. What are the features of the soil?
  3. What is the planned budget?
  4. Is it possible to connect to electricity?
  5. Can you make a septic tank yourself or do you prefer to buy a ready-made device?

How many people will live in the house

This setting affects performance. To determine it, you need to multiply the number of inhabitants by 200 liters, because that is how many drains per day, according to the standard, form one person.

Wastewater stays in the treatment plant for about three days. Therefore, productivity must be tripled in order to obtain the required volume of the station. It is also necessary to take into account the possibility of the arrival of guests, as well as decide whether the house will have such sanitary equipment as a bathtub, dishwasher and washing machine.

The number of residents affects the type of building chosen and the design features.

If it is planned to live in a house with a small family only in the summer, then the drive will be enough. To service a year-round home, you should choose a cleaning station.

The number of users determines the number of soil-filtered septic tanks. So, for a house in which 3 people will live, a single-chamber septic tank is enough. If more than 1 but less than 10 m3 of wastewater is generated per day, it is recommended to install a device from two tanks.

Aeration stations do best with large volumes.

Features of natural conditions

The depth of penetration of the primer and the type of soil determine whether it is possible to equip a soil filtration stage that will work effectively only on sandy loams and sands and low GWL.

The scheme of occurrence of groundwater

It is possible to install post-treatment on loam and clay, but these works will require a lot of time, money and physical costs.

The design features of septic tanks depend on the depth of soil freezing. A large neck allows you to deepen the device. Among the finished products there are options for installation in the ground with a deep point of zero temperatures.

Septic tank with sealed chambers

If you need to install a drive on heavily freezing soils, then you should give preference to vertical tanks. But in areas with a nearby primer, it is better to mount horizontal storage tanks.

Scheme of installation of a vertical septic tank

With a significant amount of wastewater and unsuitable natural conditions, it is better to choose a biological treatment plant. True, their cost will be higher.

Local sewerage costs

The amount of money that the owner of the house can allocate for the arrangement of the sewer system remains one of the main parameters for choosing a septic tank.

The most expensive are prefabricated plastic treatment plants, especially those that aerate wastewater. There are models produced in Russia and proven by users: Topas, Astra. You can also purchase European septic tanks, for example, Uponor. On average, biotreatment stations cost 80-100 thousand rubles.

If natural conditions allow, then you can opt for ready-made septic tanks with soil aftertreatment. Among such devices, the most popular are the Tank treatment plants, which cost about 35-50 thousand rubles, excluding the additional stage. An oxygen-free septic tank can also be equipped from improvised materials, for example, from eurocubes, especially if you purchase used containers that cost about 4-5 thousand rubles.

The design of a septic tank from eurocubes

The cheapest option is storage tanks.

The price of the finished product is also affected by what it is made of.

  1. Concrete rings are a traditional and inexpensive material for septic tanks. But for their installation it is necessary to hire lifting equipment, which is not cheap.
  2. Ready-made plastic septic tanks are also often used, they are more expensive, but they can be released into the pit by 1-2 people. In addition, you can make a tank from a thick-walled pipe of large diameter or use eurocubes.

Note! Plastic products are exposed to the ascent under the pressure of groundwater, so they must be installed on a concrete base, to which the container is attached.

To save yourself from the need to inhale odors from cesspools, it makes sense to buy a septic tank for a private house, having previously studied its features and giving preference to a specific variety. The device will save the residents of the house from any trouble. With the constant residence of a large number of people on the territory of a private house, the drain pit simply cannot cope with the task and it will need an assistant, who can become a septic tank.

What is a septic tank

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

What is it needed for

Owners of country houses, when arranging sewage, must ensure that wastewater is treated, 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 the soil. Before you make a septic tank in a private house, you should understand its structure and operation.

Device

During the construction of the cottage, it is necessary to pay special attention to the arrangement of an autonomous sewage system, since there is no central one according to the project. The device of a septic tank in a private house allows you to solve problems with the removal of household waste and their cleaning. The work is carried out in three stages:

  • Sewerage from a private house is collected in sealed plastic containers of a local treatment plant.
  • Inside the septic tank, particles are separated into heavy and light particles. The former settle at the bottom of the well, while the latter enter the next compartment.
  • Aerobic purification is not always possible, so anaerobic purification often occurs. Impurities are filtered, and the formed methane is removed by means of an exhaust pipe.

Types of septic tanks for a private house

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 for private houses are used less frequently due to time, power and material costs. However, concrete structures are considered more durable. The new ones include ready-made plastic septic tanks for the home, which have several more subspecies. Of the undoubted advantages, one can single out the cheapness, practicality of plastic, and the lightness of the product.

Cumulative

Manufacturers of septic tanks installed in private homes understand that it is impossible to do without a sewer system, so they offer a wide choice. The use of special tanks often becomes a solution to the problem. A storage septic tank is a container where household water flows through pipes, pumped out as it fills. Calculations of the volume of liquid must be made independently and, based on this, order a storage tank of the desired size. This option has a number of features:

  • Installation of drainage wells is not required, which has a positive effect on the cost of the system.
  • The tank itself for a private house will be expensive, despite the simplicity of the device.
  • The owner of the house can independently decide where the septic tank will be installed. However, everything needs to be thought out so that the entrance of the sewage truck is unhindered.
  • It will be expensive to pump out waste, therefore, if domestic water accumulates quickly, then a single-chamber septic tank is not your option!

It is impossible to ensure a comfortable life for permanent residence in a private house without sewerage. 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 of a popular septic tank, undergoing primary treatment there. There is a separation of large particles and fats that settle on the bottom.
  2. Waste is sent to the second tank of the three-chamber septic tank, where cleaning continues more actively.
  3. The sludge enters the first chamber, and the treated effluents enter the third, where the final and main stage takes place.
  4. Completely purified water through the secondary sump enters the well.

With post-treatment

Waste that has passed through a septic tank cannot be considered completely clean water that can be dumped into a reservoir or soil. Sometimes soil cleaning is indispensable. The design of a treatment plant for a private house depends on various parameters: the characteristics of wastewater and soil. Soil filtration is more costly, as you will need to install:

  • absorbent trench,
  • sand and gravel filter,
  • filter well,
  • filter fields.

Septic tanks for the 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: 11328 rubles.
  • Characteristics: the device pumps out sewage, accumulating them in the 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:

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

There are entire autonomous stations for deep biological treatment. In a private house, they will be appropriate:

  • Name: Unilos Astra 3.
  • Price: 66300 rubles.
  • Characteristics: container for collecting and filtering sewage, occurring in several stages.
  • Pros: Easy to use, does the job well.
  • Cons: none.

The cost of installing a septic tank

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

Septic tank for a private house: how to choose, reviews
A septic tank for a private house is a solution to problems with sewage and getting rid of the unpleasant odors of liquid waste. Learn about the types of devices and why you can't do without it.



A practical and successful version of the sewerage device on its site - a septic tank - is a type of treatment plant that allows you to clean and dispose of wastewater. How to choose the right septic tank for a private house? The owner of a country dwelling usually, when choosing a design, pays attention to its price and performance. The last factor will determine how effectively the product will cope with its intended purpose. The variety of these treatment facilities on the modern market will make even the most sophisticated consumer in these matters confused. Local installation, included in the sewer system and used to collect, settle and purify polluted water from the home. For an ordinary country house, they are of the following types:

Filling type - the structure can be made independently using concrete rings, Eurocube, etc.,

Settling tanks with post-treatment through the ground,

Installations for deep cleaning.

When choosing the best option for a septic tank, you should also pay attention to the material of its manufacture, the type of soil where it will be installed, the purpose of the dwelling (for stationary or seasonal residence).

Types of septic tanks for a country house

Previously, when the production of plastic septic tanks was not so massive, reinforced concrete structures were more popular, which were assembled in stages. Cleaning systems made of metal were also used. Today, wastewater treatment most often occurs with the help of ready-made plastic installations. These products are reliable and durable. A high level of sealing ensures the environmental safety of the installations. Depending on the performance characteristics, they are classified according to different criteria.

By type of filtration

The classic storage option is an analogue of a conventional settling pit into which wastewater flows.

Accumulative model of a septic tank U1250 with a volume of 1250 l (Cost about 25,000 rubles)

In such tanks, water is stored until it is pumped out by a sewage machine. Storage plants require regular cleaning. Although the cost of such containers is small, but the frequent call of machines for cleaning is an expensive “pleasure”. Therefore, such a choice can hardly be called economical.

With soil cleaning - this option defends and cleans drains through a special drainage field.

Model Rostock 1000 with a volume of 1000 liters (Cost about 25,000 rubles)

Water is thrown out, and sediment remains in the tank itself, which must be removed 2-3 times a year using special equipment. As a result of treatment in such a septic tank, the water becomes 60-85% cleaner. Energy independence and ease of operation are the advantages of such a structure. But it cannot be installed in areas with high aquifers due to poor cleaning through soil filters.

Septic tank with deep biological treatment - in this case, you can achieve a high level of wastewater treatment (98-99%) and even reuse the liquid for household needs or for watering the garden.

Model Dochista Profi H5 with a volume of 1000 liters (Cost about 65,000 rubles)

In this option, all types of wastewater treatment are used: chemical, biological, mechanical. Such tanks can be installed in any type of soil, they do not rot and can serve for several decades. The disadvantages of biological septic tanks include their energy dependence. Therefore, in areas where power is often turned off, it will be difficult to achieve the normal functioning of the installation.

By material

From reinforced concrete - this option can be chosen for houses where they live off-season, that is, all year round. They serve for a long time, but need good waterproofing and are quite difficult to install.

Plastic containers can be installed in areas where the groundwater level is high. Plastic septic tanks for a private house are not subject to corrosion and are not afraid of the influence of aggressive environments.

Metal tanks are made of stainless steel. However, compared to plastic and concrete counterparts, they are not so durable and practical. In addition, such septic tanks are quite expensive.

A horizontal septic tank is most often chosen for areas where water from the ground rises high in the autumn-spring period.

The horizontal container has the form of a cylinder and is made of plastic or stainless steel. Suitable for installing a country house with a large amount of wastewater (10 or more cubic meters).

A vertical septic tank burrows deeper than a horizontal tank.

Such products are suitable for installation in a sewerage system with a small amount of wastewater (up to 2 cubic meters). However, such a tank is more airtight than the horizontal version.

Sometimes a combined version of horizontal and vertical septic tanks is used, where each tank is responsible for certain wastewater from the bathroom, kitchen or toilet.

By location

Underground - a more common version of the design, which is buried to a certain depth. At the same time, the landscape of the site is not affected.

The ground version of the structure is used if the geology of the site does not allow the installation of an underground version due to the high level of groundwater. In this case, the septic tank will spoil the landscape of the site, so it should be mounted away from the viewing angle.

What to consider when choosing a septic tank

In order to choose the right and buy a septic tank for a country house or a dwelling located in the private sector, you should take into account the purpose of the premises itself.

If the house will be used only during a certain season, then a simpler version of a sewage treatment plant will do.

Water consumption per day is also taken into account. Based on this indicator, the required performance of the septic tank is determined. Water consumption depends on the number of people living in the house.

Soil characteristics are also taken into account. The possibility of installation on site should be determined. After all, the territory itself must meet sanitary standards: the distance from the septic tank to the residential building is 5 meters, from the septic tank to the well or well - 30 meters. If the site is small, then it is unlikely to meet all the necessary requirements. In this case, preference should be given to a more expensive option - sewage with biological treatment.

The location of the septic tank on the site

At the site where the storage tank is installed, entrances for a sewage truck should be provided.

Best option: summary

To correctly choose a septic tank for a country house, you should take into account all the recommendations and make the necessary calculations. The current budget also matters, because some types are more expensive, but are not always an appropriate construction option in a particular situation. An optimally selected design model will be a guarantee of environmental safety and cleanliness of the soil, and timely maintenance of the tank and pumping out wastewater (if provided for by the instructions) will extend its service life for a long time. The best option for a sewer tank will allow you to build a high-quality sewer system on the site and significantly improve living conditions in a private house.

Which septic tank to choose for a private house?
How to choose the right septic tank for a private house? The owner of a country dwelling usually, when choosing a design, pays attention to its price and performance.



An overview article on how to correctly choose the right septic tank for a private house.

First: proceed from their number of people who will use the septic tank

Each person will need at least two hundred liters per day, that is, if there are five people in the family, then the septic tank for a three-day stay in it should have a volume of at least three cubic meters.

It is also worth considering the volume of salvo discharge of water, it comes from several sources at once (this is a bath, shower, sinks, toilets). If you calculate the water consumption incorrectly and exceed the flow volume, this will affect the quality of water treatment.

Second: Frequency of use

Aeration units such as "Unilos", "Topas", "Astra", "Bioxi" are perfect for year-round operation. If the flow of effluents ceases, then the activity of microorganisms is inhibited.

In order to use the septic tank occasionally, it is necessary to bring additional food into the sewer, most often it is semolina, pet food, kefir. After receiving top dressing, the activated sludge biocenosis is restored, and the septic tank is operating normally.

Third: a way to divert the drain

Usually there are three ways to remove wastewater:

  • Into the ground - this method is suitable if the soil consists of sand or is sandy loam. Drains go into a filter well with a crushed stone or gravel cushion at the bottom,
  • In the "stormwater" - this method is suitable if the degree of filtration is approaching 98%, since you can get a fine for water pollution. The method is appropriate when your site has soil that does not absorb water well, for example, clay, or if you have an excessively high level of groundwater,
  • In an intermediate well - the method is suitable for several houses sharing one station. This well is built of concrete, and water does not leave it, it is dumped onto the terrain using a drainage pump.

The discharge of water into a common ditch is prohibited due to the fact that aeration stations cannot completely destroy helminth eggs. Therefore, there is a risk of infecting other residents with intestinal diseases.

Fourth: The depth to which the soil freezes in winter

You can find out how much the soil freezes in your area by focusing on SNiP 23-01-99. For example, in the Moscow Region, the soil freezes by 1.4 m.

That is, if you plan to use a septic tank in the winter, you need to lay it below the freezing point, otherwise you risk an accident.

Fifth: Station cost

The Topas and Astra brands are similar and have approximately the same price tag. The differences between them relate to design features (one compressor is installed in Topas, and two in Astra), the number of modifications in the depth of the underwater pipe, and the hull material. Bioksi stations provide for the possibility of processing a larger volume of runoff with a similar number of users. Therefore, the price tag for the products of this brand is slightly higher. For a private house, the option is optimal.

Also on the market there is a firm "Tver", which offers a combined type of treatment systems. These septic tanks have a chamber for anaerobic processes. In fact, it is a complex of a septic tank and an aeration unit. These systems are ideal for occasional use, but they are more expensive.

How do treatment plants work?

The compressor supplies small air bubbles to the aeration tanks, which cause oxidation. Then the wastewater is pumped into a biofilter or aeration tank, and the remaining organic matter is destroyed in it. If you have an aeration tank, then in it a mixture of water and sludge is sent to a secondary sump, where the effluent is separated into water and sludge, and bacteria are involved in the processing of organic matter. Aerobic bacteria are used here. The biofilter, in turn, uses anaerobic bacteria that can exist in an oxygen-free environment, therefore, oxygen supply to the chamber is not necessary. Purified water is either removed by gravity or with the help of special mechanisms, sludge remains.

Overview of units on the market

Consider the most popular settings.

Topas Station

Domestic production, one of the first in Russia.

His work is based on the combination of biological treatment with fine bubble aeration (artificial air supply) for more efficient and faster oxidation of domestic wastewater constituents. Biological purification is the biochemical destruction of organic substances by microorganisms (bacteria). In this type of installation, aerobic bacteria are used, due to them, the processes of biochemical destruction of organic substances occur.

Septic tanks of this company have a large number of modifications:

  • Based on the number of people living, modifications have been developed for four, five, six, eight, nine, ten or more people who live in a private house, in a country house, in a cottage,
  • Modifications that take into account the depth of the pipe that leads the drains out of the house,
  • Septic tank models can have one or two compressors,
  • Septic tank models may have a drainage pump,
  • In addition to modifications for the house, the company has developed septic tanks for a holiday village, a camp site, a country community with a capacity of fifty, seventy, one hundred, one hundred and fifty inhabitants.

You can safely choose the products of this brand, since this is one of the most thoughtful companies with many options, and the company's consultants will select the option that suits you, taking into account the characteristics of your site and your needs.

The positive aspects of using the autonomous wastewater treatment plant "Topas" include:

  • A wide product line, you can choose a model based on the number of people living, modifications have been developed for areas with a high level of groundwater, as well as a number of other interesting solutions,
  • Increased strength of the product, squeezing the station with soil is excluded, extrusion is also impossible,
  • Very easy to operate, easy to manage by yourself, and no need to spend money on maintenance,
  • The station is silent
  • A very high degree of water purification, which allows the discharge of water into reservoirs or into a gutter.

Among the minuses of the Topas brand stations are:

Choosing a septic tank for a private house
The article discusses general approaches to choosing a septic tank for a private house and summer cottage, as well as an overview of the Topas, Tank and Unilos models.

When a residential building is being built, then sewage is planned, as a rule, independent. Previously, a cesspool was used for all sewage, today an autonomous septic tank for a private house has become popular. These are innovative designs for wastewater treatment, which are an air-tight vessel, usually divided into several chambers.

In this device, household drains are first settled, then they are processed by special microorganisms, and then the drains are filtered. A huge selection of bio cleaners poses pressing questions for consumers, which is the best septic tank for giving with periodic rest, and which utilizer is more suitable for a permanent home? Buy a ready-made unit or make a cleaner yourself? We will try to answer these questions in this article.

Bioseptics are a local installation, which is a system of an autonomous sewer system of a private house. This treatment plant is installed in those areas where it is impossible to connect to the central sewer, that is, near country houses of non-permanent residence and country houses.

It is advisable to equip a deep cleaning station next to a river or pond.

To choose the best bio septic tank, it is necessary to understand the principle of operation of this design, which will help pay attention to the appropriate parameters when choosing a tank. So let's see how this design works:

  1. Wastewater flows through sewer pipes into the first chamber, where it settles. Heavy impurities settle to the bottom, while light fractions and fats remain at the top.
  2. Then, after the primary settling, the wastewater enters the second section, in which the process of purification from organic matter continues with the involvement of bio-bacteria.
  3. In the third chamber, wastewater is finally settled and purified. After that, they go down to the filtration field, and fall into the ground, where the liquid is filtered and completely cleaned of impurities.

When answering the question of which septic tank to choose for a house of permanent or temporary residence, experts advise paying attention to utilizers that are equipped with a deep biological filter. Autonomous purification stations of this type carry out complete water purification, freeing from the need to build filtration fields.


What are the types of septic tanks?

There are many types of local septic tanks that can be used to treat the effluents of a private house: from the simplest do-it-yourself structures to autonomous installations that allow you to purify wastewater to almost 100%.

Treatment plants are classified according to different criteria:

  • by the number of wells: one-, two- and three-chamber septic tanks;
  • according to the material of manufacture: steel, reinforced concrete products, plastic and fiberglass;
  • by design features: volatile and non-volatile.

Also, bio cleaners are classified into three types, depending on the set of implemented functions:

  1. Cumulative. Such a utilizer consists of one chamber or two communicating wells. Effluent in a sealed vessel is divided into liquid and solid fractions, then the organic matter is split, and the liquid is settled. So that the tanks do not overflow, the waste is periodically pumped out (1-2 times a year). This type of septic tank is suitable for a country house, where they rest only on weekends.
  2. Settler with a compartment for soil purification. This purifier is divided into several infiltrators - chambers without a bottom, which act as filtration fields. Inside the aeration areas there is bio-activated sludge, which accelerates the decay of sewage. This type of septic tank is suitable for a seasonal residential building, for example, from May to October. Cleaning is necessary once every 2-3 years.
  3. Station for deep purification of sewage masses. This is a tank with three chambers, in which sewage decomposes in stages. First, solids settle, then the liquid with organic suspensions is biorecycled. The best models of septic tanks of this type are equipped with a compressor. Installation is expensive but effective. Ideal for a private permanent home. Pumping out will be required no earlier than after 5 years.

In order for the closed sewer system to work more actively, it is recommended to equip an anaerobic septic tank for it, which implies the settlement of special bacteria in the primary treatment chamber. These microorganisms feed on organic matter and do not need oxygen. This measure will accelerate the disinfection and dissolution of waste.

If you remove the ventilation pipe from the post-treatment chamber or connect an air compressor, then you will get another aerobic septic tank. To do this, it is necessary to add special microorganisms to it, which process organic substances with the access of oxygen.

Biological decomposition of sewage by one or another type of microorganisms makes it possible to purify waste to the state of process water.


What to look for when choosing?

To solve the problem of which bio septic tanks are better to choose for a private house, it is necessary to consider the problem from several positions:

First, you need to decide whether to make a sump yourself or purchase a ready-made tank. In the first case, the structure is made of bricks, concrete rings or tires. However, such a cleaner is only acceptable for a house with seasonal or periodic residence. For long and safe use, it is better to choose a factory model, even the cheapest one, since the purchased version complies with all environmental and sanitary standards.

At the same time, it is not advisable to purchase the most expensive treatment plants, which allow you to drain purified water directly into a reservoir, for private use, but for several households it is not so expensive. For individual use, it is better to choose a two-capacity utilizer. The first compartment collects sewage and performs their primary purification, and the second one filters the liquid and drains it into the ground, and not into water bodies.

Secondly, it is necessary to choose the material for the manufacture of the tank. This criterion affects the service life of the vessel. So, for the manufacture of cleaning stations use:

  1. ZHB rings. High-quality reinforced concrete rings are not subject to corrosion for a long time, have a large margin of safety, but their installation requires the involvement of special equipment.
  2. Plastic. Reservoirs made of various polymers are light in weight and low in price. However, this design is very unstable, and during installation the vessel must be kept upright at all times. In addition, plastic is damaged by rodents and frost.
  3. Metal. Septic tanks made of this material have the greatest strength, as well as affordable cost. However, the metal is easily corroded, so the tank must be waterproofed, both inside and out. In addition, the installation of a metal sump is impossible without special equipment.
  4. Fiberglass. The most durable and practical utilizers are made from this material, since they have chemical neutrality, as well as other positive qualities: strength, lightness, resistance to temperature fluctuations.

Thirdly, you need to consider the type of soil on the site. Recommendations for specific conditions:

  • for sandy soil, it is better to install a utilizer with a biological treatment function, as a result of which the water immediately merges into the sand. The filtration field is recommended to be placed higher;
  • in clay soil, in addition to bacterial purification, wastewater must overcome the sand filter. Then the purified liquid is poured directly onto the ground;
  • in the case of a high line of surface water deposits, the best solution would be a polymer tank with a bio-cleaning function. In this case, the septic tank must be weighted or securely fixed.

How to choose the volume and size of the wastewater purifier?

The capacity of the waste disposal unit is calculated based on the average daily rate of sewage sewage per person (bath or shower, toilet bowl, sink - about 200 liters), the number of people living in the house and a three-day supply. If the family consists of four people, then the required volume of the septic tank is calculated using the following formula:

200*4 people*3 days = 2400 liters

If guests often come to a country cottage, then the result is increased by 2/3:

2400 * 1.66 \u003d 3900 liters.

The optimal depth of the septic tank is from 1.3 to 3.5 m.

Depending on the final result of the required cubic capacity, according to the table, a tank model is selected:

In this case, the depth of groundwater is important. For a single chamber model, groundwater must be below the bottom of the tank. For a two-chamber version, they must pass 1 m below the bottom of the last stage (filter). If the groundwater is at a depth of more than one and a half meters, it is technically difficult to equip filtration fields for a three-chamber reservoir, especially on waterproof clay soils.

Tips for choosing a cottage with occasional residence

If households visit the home on weekends and use a minimum of plumbing equipment, then a multi-section septic tank is not needed. Summer residents, as a rule, prefer low-performance, inexpensive, single-chamber utilizers. Unlike a cesspool, crushed stone and sandy layers-filters are poured into such drives, which provide 50% purification.

Experts recommend that it is better to choose a compact two-section mini-septic tank with settling and infiltration chambers. If the volume of drained sewage does not exceed the passport norms, then such a design perfectly fulfills the functions assigned to it.

Before choosing a small storage septic tank for a country house, you should familiarize yourself with its features:

  • mini-septic tanks are sold complete with activated sludge, which is populated with anaerobic biomaterial;
  • after the processing of organic waste, the water settles and is purified in the well, after which it enters the soil;
  • storage septic tanks are made of reinforced polymer, which is resistant to temperature extremes;
  • compact containers are easy to transport on a regular car, and they will not cause trouble with unloading;
  • You can install such a utilizer alone, but it is better to do it together.

Recommendations for selection for a permanent residence

For an average family that permanently lives in a country house, the best option would be a sump with two or three sections, which is a combination of a one- or two-chamber drive and a septic tank filter. The first two containers (settlers) are airtight, and the third one is without a bottom; a layer of sand and gravel is poured into it, which additionally filter the liquid before descending into the soil.

If the utilizer is filled, then it is pumped out by special sewage services, bio components and filters of the septic tank must be changed every 3-5 years. The multi-chamber sump purifies sewage up to 95%.

Which unit to choose for a house with permanent residence, so that the drains are as clean as possible, and pumping out as little as possible?

A good option in the presence of a high boundary for the passage of groundwater would be a multi-chamber utilizer with a biofilter. This factory. The model, manufactured in an industrial way, consists of 4 sections:

  • sump;
  • an anaerobic chamber for the decomposition of large waste;
  • separator with a filter with bacteria;
  • aerobic septic tank (similar to the drainage field).

The best choice would be a septic tank with a drainage field that combines several wells and a filtration zone. Such a complex requires an area of ​​​​not 30 m2. At the same time, the minimum distance between the sump and the house is also at least 30 m.


Rating of septic tanks for a country house

It is enough to go to a specialized store and see the variety of septic tanks that it offers, and the consumer will face the problem of choosing the best option. Therefore, we invite you to study the ranking of the best non-volatile and volatile wastewater purifiers, which is compiled in accordance with expert opinion, analysis of sales volume and customer reviews.

TOP 3 non-volatile septic tanks:

Such tanks work without electricity and are suitable, first of all, for country houses with non-permanent residence.

  1. Tank. A simple septic tank that works on the principle of pre-treatment of wastewater by settling, biodegradation and subsequent distribution of treated water into the ground. This unit is made of durable polymer with stiffening ribs, which contributes to the resistance to increased loads in summer and winter. Approximate service life is about 50 years. Periodic cleaning is carried out every 3-4 years and pumping out to a third of the capacity once a year.
  2. Triton. This utilizer is equipped with three chambers that implement the process of removing fractions from the liquid, as well as the anaerobic decomposition of biomaterial, followed by the supply of purified waste water to the filtration site. There are models from 2 to 40 m3. When installing, it requires weighting for secure fixation. Service life 45-50 years. Annual cleaning required.
  3. BARS-Bio. The optimal choice, both for periodic and permanent residence in a private house with the possibility of creating a filtration field. In such a unit, the waste masses pass through three chambers and two biofilters that do not require maintenance. Provides a high degree of sewage treatment, which reduces the cost of reconstruction of drainage fields. Service life - more than 50 years. Requires cleaning every 5 years.




TOP 3 volatile septic tanks:

These devices require a constant connection to electricity and oxygen supply to microorganisms, so they are better suited for cottages with permanent residence. These are real deep sewage treatment plants with a high degree of efficiency.

  1. Tver. This design provides complex wastewater treatment through a multi-chamber system for receiving and treating large volumes using various bioadditives and reagents. This septic tank is suitable for installation in any soil, even in peat with an aggressive environment. The durable plastic tank resists corrosion, providing a service life of up to 60 years. Cleansing - every 3-4 years.
  2. Leader. The unit of six chambers provides complex purification of waste masses without the use of special bioactivators. Allows you to organize an ecological drain to any place (well, ditch, pond) due to the complete cleaning of sewage using anaerobic bacteria, polymer fishing line imitating algae, aeration tanks, activated sludge, alkaline environment. The service life is 55-60 years. Pumping - once every 5 years.
  3. Ecopan. Another multi-chamber device made of airtight plastic. Available in two versions: for normal soils or for high-passing groundwater. The two-layer design of the septic tank prevents the destructive effect of any soil. Completely environmentally friendly, provides a high degree of wastewater treatment. Service life - up to 50 years. Requires cleaning every 3-5 years.

Note! When creating a septic tank for a house with your own hands, it is necessary to take into account the total cost of construction and ancillary work, the purchase of compressors and other factory products.

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

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

Today they produce various types of septic tanks for a country house, which differ in performance and volume, material of manufacture and other parameters. Let's find out the selection rules and consider the rating of septic tanks for a country house.

Types of septic tanks

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

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

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

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

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

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

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

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

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

How to choose the right septic tank for a summer residence

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

Top 10 septic tanks for summer cottages

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

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

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

It is convenient when a private house is connected to a centralized sewerage system. 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 it makes it possible to obtain process water from wastewater 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. Accumulators can only conditionally be called a septic tank, this is a cesspool - a cheap option to install, suitable only for small country houses with a small amount of drains.

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 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 also make them yourself from several large-diameter plastic pipes or eurocubes. Mounting such containers is quick and easy, without the involvement of special equipment. They are durable and have become very popular lately.
  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. The brick is laid on a 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
