Sewerage for a private house from concrete rings with installation in the Moscow region. Turnkey concrete ring septic tank cost How best to make a concrete ring septic tank

Comfortable living in a country or private house is impossible without summing up all the elements of infrastructure. If it is not possible to connect to the central water supply and wastewater disposal, then an autonomous sewer system is required.

The simplest and most reliable type of such structures is a septic tank assembled from concrete elements. Most often, such structures include several chambers. The dimensions of concrete rings for sewerage, their number and installation scheme may differ depending on the total volume of the septic tank, its location on the site, as well as the specifics of the soil and the height of groundwater.

General view of the structure

Most often, a septic tank made of concrete elements consists of three separate wells. With a sufficient depth of groundwater and the possibility of increasing the height of the structure, the number of chambers is sometimes reduced to two.

Essential elements

The general scheme of the septic tank can be represented as follows:

  • receiving chamber - a well into which all wastewater from the house enters;
  • secondary sump, which performs the function of additional purification of light wastewater;
  • a filtering well through which almost completely purified water returns to the ground.

The installation of the first two chambers of the treatment plant is carried out on a concrete base, followed by sealing of all seams, which ensures the protection of the site from leakage of untreated effluents. For a filtering sewer well, installation is carried out with a drainage layer device for the gradual removal of treated effluents.

All chambers are interconnected by connecting pipes, and in the first well an opening is additionally prepared for the sewer pipe to enter from the house. In the upper part of all three compartments during installation, heavy hatches and additional rings with hatches are installed, providing technical access to the wells.

Advantages of the building

The advantages of such septic tanks include:

  • reliability and structural strength;
  • ease of installation and maintenance;
  • the low cost of the entire structure.

But it should be noted that when installing such a treatment plant in a private house, it is worth considering several nuances. The concrete septic tank is not airtight, so smell can spread from it. Yes, and with a slight depth of groundwater, this option may be ineffective.

Calculation of the future septic tank

When drawing up a scheme for future sewage, several factors must be taken into account:

  • the number of permanent residents;
  • the volume of the selected type of reinforced concrete ring;
  • the minimum term for wastewater treatment is 3 days.

It is in the bookmark of the number of inhabitants of a private house or cottage that the main mistakes most often occur. It must be remembered that the calculation must be based on the largest number of people, including those temporarily present. After all, if the septic tank is designed for the needs of a family of three, and guests come to them, then the system may not be able to cope with the volume of effluents.

Regulatory data

The normative consumption of water per day per person is 200 liters. Thus, the number of people is multiplied by 0.2 m3 and then tripled. If the system must withstand the load of water consumption by 5 people, then the daily discharge can reach 1 cubic meter, and the required volume reserve for three days involves an increase in the septic tank wells to 3 m3.

The number of concrete rings is calculated based on the volume of the chambers. The standard ring holds 0.6 - 0.62 m3, so the required volume of the septic tank must be divided by the capacity of the ring. In addition, three rings should be added to create technical chambers.

It should be remembered that even with a small number of people, the height of the well must be at least 1.2 meters (2 rings). For normal sedimentation of solid particles from primary effluents, the water column above the solid sediment must be at least 1 m.

Installation of a septic tank from concrete elements

After carrying out the basic calculations, it is necessary to develop a layout of the sewer system. According to existing standards, the septic tank must be located at least 5 m from the boundaries of the site, 10 m from the house to prevent undermining the foundation, and also 30 m from the nearest surface reservoir.

Do not forget that the maximum distance from the source of water supply is also required. If there is a slope on the site, the septic tank must be located below the drinking water intake point. After choosing a location, the installation of a treatment plant for a private house or cottage is carried out in several stages.

Soil development

When installing a septic tank that includes several chambers, it is best to prepare one common pit. To carry out all the work, it is economically more expedient to hire special equipment. In this case, the development of the soil will take no more than 2 - 3 hours.

The installation of the receiving chamber and the sump must be carried out on a concrete base to prevent the flow of raw sewage. Therefore, the bottom of the pit at the installation sites of these wells is rammed, a layer of roofing material is laid as a waterproofing and a small pedestal is poured.

At the installation site of the filtration well, the soil is not rammed, part of it is replaced with a crushed stone pillow, the height of which should be at least 50 cm. Such a filter made of coarse aggregate will allow water to freely go into the ground, and will also serve for final water purification.

Creating cameras

When installing the rings, you will also need special lifting equipment, such as a small truck crane or manipulator. First, the skeleton of each well is assembled by setting the estimated number of rings. For a better connection, the rings can be laid on mortar or special glue.

The joints of the rings with each other and with the base are carefully sealed with mortar. For additional waterproofing, liquid glass can be added to the mixture at the rate of 10 g of additive for every 1 kg of cement.

For additional protection of the well, it is better to treat the joints of the elements with mastics or coloring composites for waterproofing from the outside and inside. Such a finish will not interfere with the entire body of the well.

On top of each chamber, special reinforced concrete covers with holes for a hatch and a ventilation pipe are installed.

Connecting cameras into a single system

After installing the rings, it is necessary to connect all the elements of the septic tank into a single structure. To facilitate pipe routing, it is best to order rings with side holes. Otherwise, niches for the pipeline can be prepared using a special crown for concrete with a diameter of at least 114 mm or manually.

It must be remembered that the septic tank of the rings is designed for independent movement of drains, so the installation of pipes must be carried out very carefully. In the receiving chamber, the sewer pipe must be laid with a slope of 2 cm for each meter of length. That is why you can not take the sewer too far from the house.

The connecting pipes between the chambers must be located below the inlet level of the main drains, otherwise the flow will cycle and the septic tank will stop working. The entry points of all pipes must be carefully sealed with mortar and additionally treated with waterproofing and sealing compound.

Backfilling a septic tank

After installation of all elements of the system, backfilling of the pit is carried out. For these purposes, it is also best to hire special equipment, because manual labor will require no less payment than renting a tractor with a bucket or a loader.

It is necessary to fill the septic tank with soil removed during the construction of the pit. With a high clay content, you can add a little sand that can be more evenly distributed around the structure. After the filling is completed, the septic tank is ready for use.

With the correct calculation and installation, a septic tank made of concrete rings can become a very effective and inexpensive treatment system for a country or private house, which will serve its owners for at least 50 years.

Do-it-yourself sewerage in a private house from concrete rings: scheme, device

Concrete rings for sewerage are distinguished by their durability and increased strength.

Compared to brick laying, concrete structures are easy to install, and concrete sewer rings cost an order of magnitude less.

Installation of rings is convenient, because they are made for a tight fit.

Average term service is about fifty years.

From the article you will learn the main features of concrete wells, learn the options for pumping out the waste content, read about how to properly install such a concrete ring and what role the groundwater level plays in all this.

Advantages and disadvantages

However, it cannot be said that concrete rings are ideal, like any device, they have their drawbacks. The first is their weight.

When installing, it is necessary to use special equipment or a large amount of labor.

This also leads to difficulties in transportation, because not every car can cope with the increased load.

If you choose a low-quality manufacturer, then the walls will crumble in just six months.

On the other hand, all these disadvantages are easily corrected, you just need to approach the construction of the sewer correctly, in stages.

It is always possible to agree on a suitable transport in advance, as well as carefully select the rings so as not to install a defective product.

Most often, such material is used in the construction of wells, but the main area of ​​​​application is autonomous sewer rings in a private house and in the country.

For sewer wells and septic tanks, structures with the lowest permeability are used.

The composition of the soil rocks where the devices are mounted does not play any role. Concrete rings with a lock are used only for septic tanks and sewers.

There are also more durable devices that have metal elements inside the walls.

Concrete rings to be installed in the sewer are marked as KS (wall structure).

After that come the numbers, where the first number shows the diameter of the structure inside, followed by external indicators.

The optimal size and how to choose it?

The dimensions of concrete rings for sewerage are selected based on the design, which indicates all the calculations, the volume of the well, its type and other points necessary to complete the installation correctly and safely.

The purpose of the rings also plays an important role in the selection. In addition to marking, there are other parameters of the rings.

In stores, when buying, you can ask for tables that contain all the design parameters.

These include the thickness, volume of the device, mass. The class of concrete is also indicated. All this information is important for the sewerage scheme to be correct.

Focusing on the dimensions of the concrete structure, you can choose a place and dig a recess there.

This allows you to see the real volumes of the site that need to be done to equip the sewer.

It is important to pay attention to the volume of the structure, because then you can understand the compatibility with the volumes of the septic tank, how the ring fits in a given situation.

The mass is needed to understand which car to use to transport the device. For sewerage in a country house or in a private house, standard concrete rings are chosen according to GOST.

They are the most common in the construction of sewers. In addition, standard devices are affordable.

Additional concrete rings may also be needed.

They are much lower in height and are needed if a small size is not enough before installation is completed and a standard device cannot be used.

Some rings are suitable only for mounting with a bottom, that is, they are used at the very bottom of the structure.

The bottom itself is made of durable concrete materials with a reinforcing mesh, which allows it to withstand even heavy loads from concrete rings.

The easiest way out is to buy sewer rings with a built-in bottom. A hatch should also come with the device (it protects the container from moisture, debris, snow).

Important Features

Most often, country sewage is equipped precisely from concrete rings. Before installation, detailed calculations are carried out. Be sure to need a scheme according to which the installation will be carried out.

The type of sewage is also selected (working under pressure or by another method). It is from the concrete components in the country that you can make the installation of an inexpensive and durable sewage system.

A sump is built from the rings, and a filtration well is made nearby, the scheme of which is quite simple.

Usually, in a country house or in a private house, a design of 3 rings, a bottom and a hatch is sufficient.

If two wells are being built, then we can already talk about real septic tanks that fully clean the drains.

It is extremely important to choose the right volume of the septic tank.

Therefore, the settling time must be taken into account here.

According to the standards, it is accepted that effluents must settle in the sewer for at least three days, and for this, based on two or three people, a volume of two cubic meters is needed.

If there are more people in the house, then it would be more correct to make a two-chamber septic tank.

Since living in a country house is seasonal, the sewerage from concrete rings is cleaned with your own hands once every couple of years.

If such a sewer is used in a private house, then it will have to be cleaned every 6 months (sometimes once a year), but you cannot completely get rid of the need for pumping.

Although here the key factor is the number of residents.

Correct installation and nuances of the device

To carry out a competent installation, you must first determine the place for the sewer.

Despite the apparent complexity, in practice it is much easier to deal with this matter.

Do not forget that the main thing that you need to pay attention to when installing a well is the depth of groundwater.

The scheme is standard, it does not have any exceptions, but there are rules that are strongly discouraged from breaking:

  • the distance from the house to the sewer must be at least 7 meters;
  • the distance from the well with drinking water to the sewer, depending on the ground rocks, should be from 30 to 60 meters;
  • the distance from roads and paths to the sewerage system is more than 3 meters;
  • the neighbor's fence must be at least 3 meters from the sewer;
  • fruit trees, vegetable gardens and shrubs are also located at a distance of more than 3 meters;
  • any reservoir should be at a distance of more than 10-20 meters from the septic tank.

If the place meets the requirements, then you can dig a pit for concrete structures. But it should be 20-30 centimeters larger than the size of the ring.

The remaining space will be sprinkled with cement and sand for better fixation.

If the place you have chosen has a high level of groundwater, then clay is the sprinkling.

Such material will serve as a reliable protection against groundwater, because it has a low throughput.

In general, it is worth considering the depth of groundwater. After all, it is important that the crude liquid does not fall into the volume of water.

Therefore, such stringent requirements are set for a large distance from the sewer to the wells.

Between the bottom of the sewer (even a high bottom) and the upper layer of groundwater, it is necessary to maintain a distance of at least one and a half meters.

In addition, the septic tank must be completely sealed to prevent mixing of waters.

Often, in such cases, a reinforced concrete pillow is also installed under the septic tank, and anchor straps are attached to it.

So the water level will be protected, and the sewer will not be pushed out. Also at the bottom of the pit, a layer of crushed stone is used from subsidence of the well to groundwater.

The installation scheme is as follows: the bottom is lowered onto a crushed stone pillow using a crane or a manipulator. Then concrete structures are installed on top.

All joints should be covered with concrete mortar. In the last compartment, holes are made for pipes that are needed, for example, for pumping.

Pumping equipment is a separate issue. Most often, special sewage firms are called to pump out waste, but their services are usually not cheap.

But if you properly equip the sewer, then you will need to call services for pumping out very rarely.

In addition, there is a certain plus of a septic tank with the possibility of settling liquids - they can be removed on their own.

To prevent the formation of plugs in the sewer that impede the pumping process, it is necessary not to forget to carry out preventive work.

For example, install gratings and manholes at all sewer outlets that can be removed when pumping out, and in normal times they will protect the sewer from unwanted things: debris, dirt, etc.

Pipe joints are treated with cement. After that, they are isolated with building silicone. Waterproofing plays a vital role here.

It is best to make it from the side of the inner walls, when the installation has already been completed.

You can safely choose from a large number of pastes, mastics and dry mixes. The main thing is to apply them in two or three layers.

After reading the article, you learned how to properly install the well, taking into account the depth of groundwater, in order to call services to pump out waste water as rarely as possible.

How to make a septic tank from concrete rings with your own hands

Add to bookmarks Printable version

It is almost impossible to imagine a private house or cottage without drainage wells and outlet structures. A septic tank made of concrete rings is one of the most affordable structures of this type; it can be designed and installed by yourself with certain lifting equipment and knowledge.

Device

A drainage well, also known as a septic tank, is a special plumbing facility that is necessary for cleaning and settling wastewater. There are many types of such tanks, but concrete annular storage tanks are considered one of the most affordable and reliable. They do not give in to corrosion, do not react to temperature changes and perfectly tolerate physical exertion.

Structurally, such a septic tank consists of:

  1. Lids. It protects the pit from outside contamination, and also provides the proper level of security;
  2. reinforced concrete rings. They can be of different heights, the standard is 90 centimeters. The diameter of the ring is selected based on the needs of the owner of the house;
  3. At the bottom, the same concrete product is laid as the lid, only of a smaller diameter. In some cases, this septic tank can be left open (without a bottom), then a certain percentage of the effluent enters the soil, thereby saving space in the tank.

In addition, the design is single-chamber and two-chamber. One chamber is an example of an all in septic tank, in other words, all cleaning processes are carried out only in it. It is small in size and easy to use. A single-chamber septic tank can be easily built on its own; a system of pipes and pipes located at different heights is used to pump water out of it. It has small volumes, so it is perfect for a bath or a summer shower, but not for a large house.


Single chamber septic tank

But, a two-chamber septic tank is more suitable for a summer residence or a private house. It is characterized by a high level of reliability and cleanliness. It has two chambers - one for primary treatment, the other for post-treatment. The first one receives water directly from the sewer, here the effluents settle for several days, after which they are pumped into the post-treatment tank using a pump or other device.

two-chamber septic tank

There is also a three-chamber (overflow) septic tank made of concrete or plastic rings. The use of this well is advisable if it is used not for one private house, but for several or for an industrial enterprise. Most often, biofilters are additionally installed in it for water purification with the help of microorganisms (anaerobic bacteria are mainly used).


JB rings

The principle of operation of any septic tank made of concrete rings is similar to a standard storage tank. Through the inlet pipe, the sewer transports wastewater into the tank. There they settle for several days, under the influence of gravity, large and solid sediments fall to the bottom. Liquid waste is filtered and transported through the outlet pipe to further use.

Installation

Installation of a septic tank made of concrete rings is quite difficult to do on your own, reviews say that you can’t do without lifting equipment or several assistants. At the same time, it will not be difficult to make these very rings - you just need to make a solution and pour it into a special form. Many experts recommend reinforcing containers. For successful design, you can use ready-made drawings.


Principal drawing

Scheme and instructions for installing a septic tank from concrete rings:


The dimensions of the pit for installing a septic tank exceed the diameter by an average of 5 centimeters (this depends on the thickness of the concrete rings). After that, bacteriological filters are installed. Pumps and outlets to the sewerage.

You can buy ready-made kits for the installation of wells at any manufacturer of concrete and sanitary products.

Waterproofing and ventilation

The device of a septic tank made of concrete rings is not airtight, therefore, ventilation is necessarily developed to remove unpleasant sewer odors. For the efficient operation of the system, it is necessary to ensure the exhaust of gases arising from the processes of fermentation of wastewater. To prevent these aromas from getting into the fresh air, ventilation is led to the fan pipe.


Scheme of a well with an exhaust hood

Calculation and manufacture of ventilation for a septic tank from concrete rings:

  1. The construction of ventilation begins after the installation of the entire storage system is completed. The main air pipe is attached to the cover and is brought out;
  2. All ventilation consists of two parts: underground and ground. The first is a pipe with a diameter of not more than 100 mm, but if you have a well with a capacity of more than 4 cubes, then you need to take a slightly larger section. The second is installed above the ground and has a smaller diameter - 50-70 mm is enough;
  3. Many experts recommend that these pipes be additionally insulated and protected with a mesh from penetration of leaves and other debris into the pipes;
  4. The ground part of the ventilation must be above ground level and above the expected level of precipitation, otherwise the well will be filled through it during rains and floods.

On this, the arrangement of the ventilation pipe can be considered complete. Twice a year, its planned maintenance is provided - cleaning from litter and accumulations on the walls. Scheduled repairs are carried out every season (replacement of pipes in case of cracks).

Separately, it must be said about the waterproofing of the system. Concrete is not damaged by water, but it is highly absorbent, which can make the well work inefficient. To prevent this, it is recommended to make waterproofing for a septic tank from concrete rings.


resin sealing

To do this, after a trench is dug under it, and its bottom is compacted, a waterproofing film is laid on it. It will protect the structure from groundwater, no matter how deep the storage tank is installed. Such sealing will be very useful in areas with high GWL and heavy precipitation. To install a septic tank in swampy soils, it is recommended that the pit be concreted first, and then waterproofed.

A septic tank made of concrete rings - how to do it yourself

Do-it-yourself filtration well or septic tank made of concrete rings (the diagram will be presented in the article below) performs the function of infiltration, that is, seepage of water from the system into the soil.

This design is usually installed in a recess and is a container with a wide area and a closed top. The use of such an infiltrator is characterized by the presence of pros and cons.

  • Advantages of using in cottages
  • Device
  • Schemes and calculations
  • Location selection
  • foundation pit
  • Installation of concrete rings

What is it and why is it needed

A septic tank is the best option for cleaning domestic wastewater for a country house.

There are many ways to install this design. Manufacturers have provided a variety of treatment systems on the market.

Home-made designs are quite difficult to adjust to the reliability standards of industrial septic tanks with a multi-stage filtration system. But the simplest design is easy to assemble on your own.

Advantages of using in cottages

Peculiarities:

  1. Great filtration speed.
  2. Shallow pit height for installation.
  3. Requires free space on the site, which is not always possible to find.

Of course, when installing septic tanks, many owners of suburban areas resort to the services of specialists, but the process can be done by hand. You should first select and display a design diagram indicating all parametric characteristics.

The choice depends on the location of the site and its area, as well as the cost of water. For example, in the case of a high occurrence of groundwater, it is necessary to install a reinforced concrete slab to securely fix the septic tank in order to prevent possible lifting of the structure.

The difference between ready-made and homemade

The disadvantage of the purchased system is the high cost, but the work of high-quality structures takes place in a long-term format. Therefore, there are "Kulibins" who make treatment systems with their own hands.

Device

Let's look at the example of a septic tank made of concrete rings. This is an extremely simple design, since the structure is created from ready-made blocks. The septic tank itself is created from concrete rings, that is, a collector for settling wastewater, as well as a filtration well.

The system is installed as follows. A pit is being prepared, the parameters of which may vary depending on the size and depth. The bottom of the pit is poured with concrete, after which hardening, concrete rings are laid in the pit. Their joints are treated with sealant, which is also used for good bonding of the bottom with the walls of the structure.

Thus, a collector is created, from which effluents must enter the filtration well through special openings or sewer pipes. Pebbles, gravel or other inert drainage material is laid on the bottom. A concrete slab with an inspection hatch and a ventilation outlet is also laid on top. The structure can only be built with a truck crane, as concrete slabs are heavy.

Kinds

We list briefly:

  1. The most common are reinforced concrete structures. This is one of the most durable types. They are prefabricated or monolithic.
  2. From iron. Specifically stainless steel containers. An unpopular option, since they fail in a few years, and such material is several times more expensive than concrete.
  3. Plastic installations of factory production. In terms of service life, even reinforced concrete can be surpassed, since there is nothing to dissolve inside.
  4. By design, they are divided into single-chamber or two-chamber.

Construction: step by step instructions

Schemes and calculations

There are no technical plan formulas for this, and they are guided by the norms. And they are like this: the chambers should contain as much volume for processing as is consumed by all users of the system in three ordinary days.

It is important to know: before installation, the internal volumes of such structures must be calculated.

Location selection

It is important that the entire system works efficiently, and there are no domestic inconveniences. Therefore, before marking the selected territory, you need to make sure of the following:

  1. We do not place the structure near a residential building. We retreat more than six meters from the foundations. It is allowed to dig near garages and other outbuildings.
  2. In no case do we plan a future septic tank near sources of drinking water. The norm for such a distance is 50-60 meters.

foundation pit

The pit is prepared only after the calculation. Decide on the number of cameras:

  1. When residents consume up to one cube of liquid, then you can safely install a single-chamber installation.
  2. At a flow rate of 1.5 to 10 cubic meters of water, a pit should be dug already under a two-chamber system.
  3. A value of more than 10 cubic meters leads to additional work: three chambers for a septic tank, sedimentation tanks and a filtration well.

It is necessary to mark the area for the pit in such a way that the length and width are slightly larger than the rings themselves, and the depth is on par with their number.

Installation of concrete rings

Most often, in the technology of installing a septic tank, rings with overflow are used. And it is very comfortable if you rent earth-moving and, of course, lifting equipment. Then the pit will be even, and the rings will stand exactly horizontally.

Before planting, it is most correct to shed the bottom of the pit if there is no product (ring) with the bottom already closed. Next, you need to install the rings alternately, leveling the distortions and shifts.

Please note: the correct design will be assembled only with the help of a crane and assistants.

Each joint in the rings must be shed with concrete. And only then do sealing. Seams outside and inside are best treated with bituminous mastic. But first cement (concrete), and then sealing.

Don't forget waterproofing. It is made from the outside and the inside. And at the same time, they organize holes for pipes in the septic tank. Where there will be camera connections, sealing is also needed.

And at the very end, the covers are installed. There is no such design without ventilation. And only she will help to kill unnecessary odors. Ventilation removes methane, and this is an explosive substance (gas). It includes a ventilation background riser that needs to be brought outside, and ordinary ventilation risers that are placed on the lids of finished tanks.

If necessary, it is not difficult to assemble a budget format design. And for the private sector without frills, only such septic tanks are needed. If you take care of hiring equipment in advance, then a lot of effort for construction will not be required.

Crazy pens all with your own hands for home and garden

The cheapest fence for giving with your own hands

The sewerage scheme of concrete rings is one of the most popular among those that can be done on the site with your own hands. However, in order for it to work with maximum efficiency, it is important not to make mistakes at the main stages:

  • determination of the required volume,
  • design choice,
  • choice of installation location,
  • installation of sewerage system and communications.

Sewerage for a private house made of concrete rings has undeniable advantages:

  • structural durability,
  • mechanical strength and rigidity,
  • relatively low material cost,
  • resistance of concrete to corrosion processes under the influence of moisture and chemically active substances,
  • fast assembly.

When choosing, consider the disadvantages:

  • Concrete has good hygroscopicity, therefore tank walls need waterproofing. Otherwise, untreated water will partially seep into the ground.
  • Due to the large mass of the rings Installation requires special equipment which will require additional costs.
Sewerage from concrete rings is carefully waterproofed inside and out, this applies not only to joints, but to the entire surface

Installation and its nuances

Features of the material are directly related to some of the nuances of installation, characteristic of all types of sewers in this category, regardless of the design chosen.

What characteristics they have, read in a separate article. There is information about their types, sizes and prices.

You can talk about vacuum pumps for sewage. The types and main characteristics of the units are described.

The principle of operation of various designs

Depending on the conditions in which sewerage from concrete rings is used, the scheme is selected optimally suitable for them.

  • Single chamber models often chosen for a summer residence or a country house with seasonal residence. They require periodic cleaning with a vacuum cleaner.
  • The frequency of pumping out two-chamber structures noticeably less. Such options are often considered universal. With the right choice of volume and proper installation, they provide a fairly high degree of cleaning, while such models require less space on the site than three-chamber ones, it is easier for them to find a place that meets all sanitary requirements.
  • Three-chamber country sewerage from concrete rings is also suitable for private houses with permanent residence, as well as for summer cottages, where, in addition to a washbasin and toilet, there is a shower, a full bathroom, and a washing machine. A system of this type is able to provide high quality cleaning with mixed (organic substances and chemical components, including detergents) pollution. Among the septic tanks with three chambers, there are volatile (in which the effluents are cleaned due to the vital activity of aerobic bacteria) and non-volatile. The former are distinguished by a shorter processing cycle and efficiency, the latter by the absence of operating costs.

Calculation of the volume of sewerage and standard sizes of rings

The total volume of the treatment plant depends on the average daily water consumption of all residents of the house. It, in turn, can be calculated by points of consumption (shower, washbasin, etc.), but it is much easier to use the accepted value - 200 liters per day for each person.

The water purification cycle is approximately three days, during which wastewater must be collected in the sewer system. Thus, for a family of three, the required volume is calculated as follows:

3 (persons) x 200 (liters) x 3 (days) = 1800 liters (or 1.8 cubic meters).

  • When choosing a single-chamber model, the entire volume falls on a single container.
  • In a two-chamber design, the storage tank is 3/4 of the total volume, and 1/4 falls on the second chamber.
  • In a three-chamber septic tank, the storage is 2/3 of the volume, and 1/3 falls on the second and third chambers in total (most often they have the same dimensions).

Many homeowners use only one ring size for all sewer tanks.

During installation, three concrete rings are usually stacked on top of each other. A smaller number is impractical due to insufficient capacity, a larger one can reduce the reliability of the design.

Since standard concrete rings have the same height - 900 mm, the volume is determined by their diameter. Many enterprises offer the manufacture of reinforced concrete products with any parameters to order, however, such rings will cost more and increase the overall cost of the structure. It is permissible to use rings with an inner diameter of 700 to 2000 mm for the construction of tanks, however, in most cases, preference is given to the two most common sizes: KTs-10 (KS-10) and KTs-20 (KS-20). The numbers in the marking indicate the size of the inner diameter in decimeters.

Elements of the sewerage scheme

A septic tank or a sewage treatment plant is the main structural element, but this is far from the whole sewerage device made of concrete rings - the scheme includes other elements that should be discussed separately.

Sewer pipes leading to the storage tank must have a slope of 2 cm per meter if the liquid is transported by gravity, without the use of a pump.


SNiP strictly regulates the installation of manholes along the entire length of the pipeline:

  • at the junctions of lines
  • when changing parameters (slope of communications or their diameter),
  • when bending the pipeline.

For rectilinear communications, the distance between the manholes is determined by the diameter of the pipeline:

  • up to 150 mm - 35 meters,
  • 200 mm - 50 meters.

In summer cottages, sewerage is not installed too far from the house, so the number of wells is rarely more than 1-2.

For volatile modifications, a ventilation pipe is required, as well as, which is better to choose with the ability to control performance and with a timer.

In the sewerage system in the country house made of concrete rings, the bottom filter is not suitable in all cases for the effective drainage of purified water. Dense soils (clay and loam) do not have good water permeability, which reduces the rate of drainage. As an auxiliary device, perforated pipes can be used that come out of the lower part of the chamber with purified water (the second or third, depending on the design) have plugs at the ends and are located parallel to the ground at a shallow depth. Such devices increase the drainage area.


In the case of a very high clay content in the soil, it is preferable to have a suction pump that will transport the treated water to a drainage ditch or irrigation tank. In the second case, the water quality requires testing in the laboratory.

Another option for arranging sewerage on the site is. How to do it, you can learn from another article.

For those who are going to build an outdoor toilet, our article may be of interest. This option is environmentally friendly and simple device.

We told how to conduct water supply from the well.

Placement of a septic tank

It may seem that in order to ensure the slope of the sewer pipeline, it is easier to install concrete sewer rings in the lowland, however, in this case, rain and melt water will enter the tank, overflowing it.

Reservoirs must be installed no closer than 5 meters from a residential building, and also maintain a distance to sources of drinking water (30-50 meters) and 30 meters to open reservoirs.

How to make a sewer from concrete rings is shown in the video.

Reinforced concrete rings are widely used in the arrangement of sewers. Durable and durable products are relatively inexpensive and make it possible to build local septic tanks (single-section ones are called cesspools) and manholes at minimal cost. It is easiest to equip the sewerage system with concrete rings.

They are relatively easy to install, operate without much difficulty and protect the septic tank well from precipitation or freezing. Learn how to make a sewer from concrete rings from this article.


A manhole is assembled quickly. A crane is used to move the rings. During the installation work, reinforced concrete rings are firmly fastened together with a “lock” connection. The design turns out to be very reliable, and the influence of soil mobility on it is reduced to a minimum level.

It depends on the amount of groundwater whether it is necessary to lay waterproofing of concrete sewer rings from the inside. It is made as a layer of polyethylene.


For installation work, 2-4 people and a rented excavator are enough. If you equip the country sewerage from concrete rings, then you can not worry about the possible leakage of drains into groundwater.

Commercially available perforated septic tank covers greatly simplify installation. And thanks to the groove connection of the sewer rings, the subsequent sealing of the structure becomes easier.

As a rule, in suburban housing construction, concrete sewer rings with a diameter of 1 m are used.

Too large should not be taken - because of them, groundwater can get into the ring or the soil can dry out. And the latter will eliminate the need for the installation of a sewer system. The concrete ring acts as a conductor for the sewer system assembly and sewage sump, cesspool.

How to make a sewer from concrete rings?

To install a concrete ring as a septic tank, you need to dig a foundation pit, carefully compact it. Due to the tight tamping, additional work associated with undermining will not be necessary if the ring gets stuck in the hole.

Despite the advantages of these products, one should also remember their disadvantages: RC rings are quite heavy. Additional charges are required to deliver and install them.

The large weight of the rings causes the likelihood of cracks in them with an uneven load on the products. But the advantages of reinforced concrete rings are still much greater than the disadvantages. No wonder they are leading the construction market.

Main technical characteristics

Many types of construction work cannot do without reinforced concrete rings. Sewerage for a private house made of concrete rings is widely popular. These durable products are made from concrete and rebar designed for long-term use.

With minimal building skills, you can make a sewer from concrete rings with your own hands, but if you are not confident in your own abilities, contact professionals.

For a reasonable fee, they will quickly and efficiently perform the installation of the necessary products. In addition, they will help you choose the right design for your site and purpose.

Installation of concrete rings for sewerage and operation

The popularity of concrete rings in the presence of plastic analogues for sale is easily explained. Concrete products have many advantages, which include affordable cost and the ability to maintain preventive work along with a long service life.

Reinforced concrete sewer rings are durable and can be used up to 5 years.

Products are resistant to low winter temperatures. With high-quality insulation, they are not affected by alkalis, water and acids.

Concrete rings are used as a septic tank for sewage, the implementation of which is possible in several modifications:


When deciding to build a septic tank and thinking about how to install concrete sewer rings on the site, you need to understand: such work requires certain knowledge and skills.

But awareness of the options for implementing a septic tank simplifies the process of creating it. By choosing the right reinforced concrete rings, you can equip the sewerage system that works as efficiently as possible.

Do-it-yourself installation of concrete rings for sewerage - step by step

Before proceeding with the arrangement of the receiving collector for drains, you should prepare for installation work. The septic tank is calculated by volume, which is influenced by the number of people living in the house, the volume of drains.


In accordance with the project, you need to buy ring elements of the required diameter and configuration, purchase and bring sand, gravel, cement, bitumen and liquid glass to the site.

If the system is planned to be constructed by a mechanized method - with the help of special equipment, you need to agree in advance on renting a crane. For unhindered entry of vehicles to the site, it is necessary to prepare access roads in advance.

Sewerage from concrete rings is installed in stages. The most difficult thing is to carry out earthworks. To equip a septic tank, you need to follow a few steps:

Increasingly, instead of the usual cesspool, they make a sewer in the form of a septic tank - a well or a system of wells in which wastewater sequentially wanders, is cleaned and filtered. Such a modification of the sewer relieves the owner of the house from the need to use sewage services. Installation of a septic tank costs about 30,000-35,000 rubles.

Design calculation

Although the prices for sewer concrete rings are through and with a bottom at an acceptable level, it is necessary to select reinforced concrete products with a suitable diameter in order not to overpay for the rings and make the installation process easier.


The volumes of the most popular models KS 10-9, KS 15-9 are 0.23 and 0.40 m3, respectively.

The volume of a septic tank is calculated as the product of the number of residents in the house, the daily rate of individual water consumption (150-200 liters) and the number of days during which the well is filled with water (usually 3 days).

Another calculation option is to multiply the total daily water consumption in the house by a factor in the range of 2.5-3.

Septic tank from reinforced concrete rings is a system of autonomous drainage, reception, treatment and disposal of wastewater, based on mechanical and biological treatment, the efficiency of which depends on the configuration and can reach more than 98%. The principle of operation of a septic tank made of reinforced concrete rings uses the same mechanisms of biological wastewater treatment and mechanical settling as septic tanks of any other modification.

Schematic diagram of a septic tank made of reinforced concrete rings

In the same way, in the first (receiving section), bacteria work, processing products of biological origin that enter the septic tank from the internal sewerage system, which subsequently, by means of bypass and settling in the following sections of the structure, are discharged into the drainage, into the aeration field or outside the site.

In order to allow the products of biological processing to fall to the bottom and to the next section there was an overflow of mostly purified technical water, the first section of the septic tank is usually made deeper than the subsequent ones.

The exception is the last section of the septic tank made of reinforced concrete rings, the depth of which may be greater than the others, when it is possible to achieve effective drainage cleaned after the runoff into the ground. This is possible if there is a sandy layer of soil at the required depth.


Septic tank made of reinforced concrete rings

The volume and number of septic tanks is determined by the number of permanent residents in the house and the volume of peak loads on the sewer. It is also necessary to take into account the geodetic features and layout of the site.

After domestic wastewater passes through the biological treatment stage and bypasses between sections of the septic tank, during which the contaminated particles that accidentally fall from the storage tank settle, the process water purified to a level of 95-98% enters the drainage well. Further, it is discharged by gravity or forcibly (using a circular pump) outside the site, or to a filtration field specially equipped with sand and gravel.

Prices of septic tanks depending on the volume of performance

Here you can order septic tanks from reinforced concrete rings for a Country House or Turnkey Dacha from 29.900 rubles.

A septic tank with a volume of up to 10 rings is installed by our specialists in one or two work shifts. In cases where groundwater is close enough to the earth's surface, the depth of the first section can be reduced to 2 rings. If the geodesy of the site has provided you with a happy opportunity to use an economical technology for arranging sewage through the construction of a septic tank from reinforced concrete rings, our specialists will perform all the necessary work in the shortest possible time and on the most favorable terms for you.

Advantages of septic tanks made of reinforced concrete rings:

  • Simplicity and energy independence. The absence of an electrical part and the most simplified design;
  • No need for service. The system called "set it and forget it" assumes only pumping out by a cesspool machine in case of overflow of the receiving section;
  • Cheapness. A septic tank made of rings costs 2 or more times cheaper than hermetic models similar in terms of the degree of wastewater treatment;
  • Efficiency, reliability and durability. Purification of domestic wastewater to the level of 95-98%. The service life of a septic tank is up to 30-40 years.
  • Wide applicability. On more than 70% of the plots of the Moscow region, geodesy makes it possible to use the technology of building septic tanks from reinforced concrete rings.

1) OPTION No. 1 (two rings on top of each other without a bottom) for 29,500 rubles .

When installing this design, reinforced concrete rings with a lock measuring 90x100 cm are used, which are buried in the ground and as a result we get the following view:


From the room where the plumbing equipment is installed, a pipe with a diameter of 110 mm is removed. and is mounted in the upper ring through a hole that breaks through just below the ceiling with a hatch, the pipe is insulated:



A septic tank made of concrete rings with a lock with a diameter of 1 meter is a simple, and at the same time, reliable construction for a suburban sewage system. There is no constantly running electric motor inside the structure, which periodically breaks down, as happens with expensive and supposedly reliable units. During installation, no additional costs for sand and concrete are required to strengthen the walls along the perimeter of the excavation, it can be driven by a car, unlike other structures, which means there is no restriction on the installation site. As a rule, during installation, the bottom is not concreted so that the water coming from the sink, shower, washing machine, dishwashers, etc. could freely go into the ground, and the feces from the toilet remain inside, and gradually decomposing sink to the bottom. Below is a comparative table on the need for cleaning (pumping out) of thick components. The cost of calling a pumping machine is from 2 to 3.5 thousand rubles. for 2019.

The table shows the values ​​for the construction of 2 concrete rings with a lock with a diameter of 1 meter. If desired, you can increase the quantity, if the terrain conditions allow and there is a need for this, because 2 rings are 1.6 cubic meters. And that's not much compared to other options. And be sure to take into account that this is a closed reservoir, not a city sewer, with almost unlimited possibilities, which means that you should not throw any unnecessary waste and objects down the toilet!

ATTENTION, ACTION!!! A septic tank of 2 turnkey concrete rings cost 38,900 rubles. Rings with a lock with a diameter of 1 meter, a floor slab and a hatch with a sewerage pipe plant 110mm in the insulation sleeve to the house. The cost of all materials and works necessary for installation are included in the price. The total capacity is 1.6 cubic meters. Septic tank made of concrete rings price with turnkey installation!

The photo below shows an example of organizing a water supply from a well with the installation of plumbing and sewerage into a septic tank from 2 concrete rings. Sewerage pipes with a diameter of 110mm. in the sleeve of insulation. The plumbing is mounted on reinforced polypropylene pipes.

The cost of all works and materials including 2 concrete rings and a manhole cover is 129 thousand rubles More details on the page (follow the link)







2) OPTION #2. SEPTIC FROM 4 CONCRETE RINGS according to the 2 + 2 system with overflow (using bacteria) FOR 49500 rub. WITH DELIVERY AND INSTALLATION. Or from 5 rings according to the 3 + 2 scheme with overflow for 56,500 rubles.

This option also involves the use of concrete rings, but their number increases to 4, and here bacteria are used for better cleaning. The system is very reliable, and at the same time remains easy to operate and relatively inexpensive.

All drains enter the first well through a pipe. Water treated with bacteria from the surface of the first well enters the second well through a connecting pipe and goes into the ground there. Solid feces decompose and sink to the bottom. The frequency of pumping (cleaning) the first well is increased by 40% in comparison with the first option.

How to use bacteria (for example, Atmosbio Green pine 300 gr. Price: 380.00 rubles / piece): pour one measuring spoon (once a week) into a container with warm water, stir and pour into the first well or simply into the toilet and rinse with water . One jar is enough for 3 months. It is desirable to install this structure where dry sandy soil with groundwater is below the level of 2 meters. In the case of high groundwater, it is possible to install a drainage pump with a float in the second well. We pass the wire from the pump into the protective corrugation, we bring it into the house and connect it to the 220-volt electrical network. We lay the outlet pipe underground into the nearest ditch or bring it directly to the ground. Thus, we obtain an automated system for pumping out excess technical water.

Installation diagram:





In the photo below, work was done on the installation of a water supply system from a well in automatic mode with the installation of sewage from concrete rings according to the scheme 3 rings + 2 rings with overflow and a filter head.





3) OPTION #3. SEPTIC FROM 5 CONCRETE RINGS (using bacteria) FOR 69500 ​​rub. WITH DELIVERY AND INSTALLATION.

This design adds another service water ring that can be used for irrigation and a drainage system. Option number 3 is more often used for large houses with year-round use. It is desirable to install this structure where the dry sandy soil with groundwater is below the level of 2 meters, or it is possible to lead the drainage pipe into a ravine, slope or other natural depression to drain water, or install a drainage pump with a discharge pipe.

Installation diagram:


In the photo below, a septic tank made of concrete rings is installed according to the 3 rings + 3 rings + 2 rings system with overflow pipes and a filter head. All sewerage through a pipe with insulation with a diameter of 110mm. enters the first receiving well of 3 rings. Thick components gradually decompose and sink to the bottom, water flows through the filter into the second and third wells and goes into the ground. To process settled feces in the first well, bacteria can be used, just pour them into the toilet and press the drain button.

Water is brought into the house through a PND-32x2.4 pipe at a depth of 1.2 meters, the rise from the trench to the house is heated by a self-regulating electrical wire and an insulation sleeve. Inlet filter installed. The plumbing is made of reinforced polypropylene pipes. Assembled, installed and connected all plumbing.
