The construction of a sewer system on any suburban area is a complex of complex works that involves not only laying pipes, but also installing a cesspool or a finished septic tank. To install a septic tank, permission from the SES is required. There is no way to do this without collecting a package of documents. Why is this required? The problem is that groundwater and the soil itself can be contaminated by runoff and chemical waste. Improper cleaning of a septic tank with chemicals can lead to various diseases and contamination of the residential area of the entire site. Therefore, before starting work, it is necessary to design a sewer system, collect a package of documents and submit an application to the SES.
Before constructing a sewer system, you need to make a project, then collect the necessary documents and submit an application to the SES.
How do modern cleaning systems work?
Modern treatment facilities have to process wastewater, which contains large quantities of all kinds of chemical compounds. Entering the purification system, biomass dissolves in water, but not in full. Everything that did not go through the composting process (simply did not decompose) goes into the soil, and subsequently into aquifers.
The undissolved masses (infiltrate) contain a huge variety of pathogenic bacteria, which can cause damage not only to nature, but are also very dangerous to human health. In addition, the consequence of such treatment of wastewater is certainly the appearance of unpleasant odors. In this case, preserving the septic tank for the winter is a mandatory measure.
According to current sanitary standards, such a device is considered a gross violation. If such a structure is identified on a site, SES representatives are required to issue the owner a fine in the amount of 50–100 thousand rubles, which is accompanied by an order to dismantle the existing structure. Therefore, it is worth abandoning the use of such a design or modernizing it taking into account SNiP standards.
However, the situation can be presented in a slightly different interpretation. For example, a homeowner decided to install a wastewater system on his property. To do this, he built a sealed cesspool and started the system himself. However, if the environmental situation is bad or as a result of a trivial complaint from neighbors about unpleasant odors, representatives of the SES will come to the person with an inspection, during which the homeowner is obliged to provide all permitting documentation for the installation and operation of the treatment plant.
Such documents confirm the tightness of the structure, as well as its technical compliance with the standards of maximum permissible concentrations (MPC). The lack of permitting documentation, which also displays information about how often the poplar septic tank should be serviced, threatens the owner of the septic tank with a serious fine and subsequent dismantling of the structure.
Features of modern septic tanks
A local treatment facility in which wastewater from a home is collected and treated is called a septic tank.
The simplest models of these treatment devices operate on the principle of settling wastewater and further decomposition of sludge due to the activity of anaerobic organisms. Usually, after such a device, the wastewater is not sufficiently purified. Sanitary standards prohibit the discharge of such wastewater into the ground or open water bodies, so wastewater requires additional treatment, which it undergoes in filtration fields or in drainage wells.
Modern septic tanks for a private home are autonomous deep treatment stations that use mechanical and biological principles of wastewater treatment. Thanks to this, a high degree of wastewater purity is achieved, reaching 98-99%. Sanitary standards allow the discharge of such wastewater into open water bodies or ground, since they do not pose a threat to the environment.
Important: in addition to the purity of wastewater, local treatment plants are subject to other requirements for placement and installation.
How to properly install a sewer system in a private house with your own hands?
You can set up a sewerage treatment system with your own hands, the main thing is to do all the work in accordance with the requirements of SNiP, using proven and most effective installation schemes for autonomous sewerage. This approach will allow you to save on work, and in this case the permitting documentation will be a certificate or passport for the septic tank.
When installing a septic tank, special attention should be paid to the quality of the concrete that is planned to be used for the foundation (bottom of the structure). For these purposes, special grades of concrete are used, which contain hydraulic additives. This ensures maximum tightness of the finished structure, eliminating leakage and the formation of unpleasant odors.
In addition, attention should be paid to the features of the landscape, the presence/absence of a slope, soil composition, proximity and direction of groundwater flow and other factors. It would be advisable to have a friendly conversation with neighbors who already use an autonomous sewer system and know what “pitfalls” can “surface” when installing it.
Our company’s specialists recommend using treatment facilities that have a monolithic base, as well as all the necessary technological openings. In the production of the selected septic tank, hydraulic concrete of the highest grade must be used. Such designs are very convenient and easy to operate and maintain - pipes with wastewater are discharged to the filtration field or to the drainage system.
Regardless of whether a conventional drain receiver or a complex cleaning station is being installed, the installation must be carried out using technology developed for a specific type of system. As a result of annoying mistakes made during the construction of an autonomous sewer system, the owners of an incorrectly designed station are faced with unpleasant consequences, which are difficult, expensive and not always possible to eliminate:
- Unpleasant odor in the house and area.
- Overflow from the container onto the ground.
- Emergency stops due to system malfunction.
- Low purity of treated wastewater.
When building an autonomous sewer system, mistakes made at the design stage can only be corrected by completely reinstalling the system. The main shortcomings are an incorrectly selected installation site, incorrect determination of depth and incorrect pipe laying trajectory.
Scheme of arrangement of a private sewer network
Wrong choice of installation location
Errors: choose a site located above the point where the drinking water intake is located; dig a pit close to the foundation wall or neighbor’s fence.
There are no uniform rules determining the exact location for installing sewer tanks. For each type of treatment system, there are restrictions, both in terms of distance from residential buildings and distance from water sources.
Planning the installation site
The higher the purity of the drainage at the outlet, the less space is required from the house. For local deep cleaning stations, 5 m is sufficient; for active and receiving septic tanks, it is better to choose a distance of 10 m. Regardless of the type of sewerage system, the distance from the buildings and fences of the neighboring area should not be less than 3–5 m. A similar rule applies for placing septic tanks near roads – a distance of 5 m is sufficient.
The distance from the well or borehole depends on the composition of the soil. The minimum is 10 m; in difficult areas with soils supersaturated with moisture, a distance of 20–50 m is required.
Important! As a general rule, if there is a slope on the site, the sewer tank should be installed below the point of water intake so that the natural flow of rainwater and surface water does not flow to the well from the septic tank.
When installing containers that require regular pumping, it is necessary to prepare a site for free access for equipment. Area - up to 20 m2, the stopping place of the sewer truck is a maximum of 4 - 5 meters from the hatch.
Incorrect pipeline laying path
Errors: the pipeline section from the house to the receiver is too long without inspection; sudden changes in altitude; turns.
The optimal length of the outer section of the pipe from the house to the entrance to the receiver is from 5 to 10 m. At a greater distance, inspection wells must be installed.
Straight line: ideal trajectory
It is advisable to plan the laying path so that the pipe runs in a straight line, or with smooth turns. In case of a sharp change in height or in the case where the angle of rotation is 90°, special connecting elements and drop wells are used.
Such systems are designed by specialists. To avoid unnecessary expenses on additional elements, it is better to carefully study the site plan along the pipe laying line, because most often difficult sections are located in places where it is necessary to bypass cables and previously laid communications.
Slope and depth: calculation errors
One of the most common mistakes when installing an autonomous sewer system is incorrect slope and incorrectly determined depth.
Error: too large or, conversely, small value of the angle of inclination of the pipeline line; excessive deepening of containers.
When installing it yourself, people often make mistakes by laying the pipe at a large angle. In fact, too sharp a slope can cause the siphons to fail due to the high flow speed inside the pipe and the appearance of growths on the inner surface: water passes into the receiver at high speed, and dense masses stick to the walls.
When the slope is not enough, the flow of liquid slows down, which leads to stagnation of drainage in the pipes and the occurrence of blockages.
Table: correct slope for pipelines of different diameters
Rule: for each pipe diameter there is a strictly defined slope indicator. In order not to be mistaken in determining the angle, it is better to use ready-made tables, where the indicators are given to simple values: centimeters of slope for each linear meter of the line.
When determining the installation depth of tanks that require regular cleaning, take into account the maximum depth from which the pump can lift sludge - 3 m.
When choosing equipment for autonomous sewerage, mistakes arise in most cases due to the desire to save money. But saving on parts and pipes is very doubtful, and can cause the system to stop due to a pipeline malfunction.
About pipes: common mistakes when choosing
Mistake: purchasing pipes for interior work and installing products of the wrong diameter.
Products for interior work will last until the first frost
Sewer pipes intended for installation indoors are gray or white. They are not designed for installation in the ground outdoors. Consequences:
- The material of the internal pipes is not frost-resistant - if the temperature changes, the plastic may crack.
- Rubber seals at the joints of connectors are made of ordinary rubber, which loses elasticity when exposed to an aggressive environment - the connections lose their tightness.
Choosing the right pipes for laying in the ground
For laying from the house to the receiver, you must choose pipes made of orange or light brown plastic. Manufacturers use this color to mark products for external systems. The optimal choice is products made of polypropylene or PVC. It is worth giving preference to plastic parts instead of cast iron. Plastic pipes are easy to transport and connect; such a pipeline will last up to 50 years.
How not to install a ventilation outlet
Mistake: when constructing an autonomous sewer system, ventilation is installed incorrectly and “forget” about the air flow. The result is impaired air circulation within the system, an unpleasant odor in the house and on the property.
Exiting ventilation to the roof height with a separate outlet
Ventilation of the external part of the autonomous sewer system must be thought out and arranged in conjunction with internal wiring.
Be sure to install:
- Fan outlet of suitable diameter in a separate pipe with a diameter of 110 mm.
- An insert with a valve for a constant flow of air into the structure up to 100 cm high above the ground surface.
Proper organization of ventilation: exhaust inside the house
It is advisable to bring the ventilation outlet to the level of the house chimneys. It is prohibited to connect a chimney and a sewer ventilation outlet; the pipe is installed separately on the roof. It is advisable to make the outlet indoors, and not along the outer wall of the building.
Why the overflow does not work: device defects
An error in the design of autonomous sewage systems with individual containers connected by overflows: incorrectly determined height and slope of the overflow pipe.
Overflow: Below the entry point of the sewer pipe
When installing several containers in series, it is necessary to accurately determine the connection points. When the overflow is installed at the same level as the entry point into the tank, there is a constant backflow of waste into the sewer pipe.
Rules:
- The overflow point should be below the entry point of the sewer pipe.
- The overflow pipe must be installed at an angle: from the supply tank to the receiving tank.
You should not neglect sealing the pipe insertion points: through an unsealed hole, drainage seeps into the ground, and groundwater along with clay gets inside the structure.
Errors in calculating the volume of a structure
Error: volume too small or sewer with too much power reserve.
When, in order to save money, they buy a unit with insufficient productivity (in fact, with insufficient volume), then the purity of the effluent at the output will not correspond to the indicators declared by the manufacturer. Due to the excess volume of liquid inside the structure, wastewater flows faster into the next container, the treatment technology is disrupted, because aeration and anaerobic treatment are strictly calculated according to the time the masses remain in the compartment.
Calculation of volume for tanks of different shapes
When installing a structure with too much reserve volume, the drainage stagnates inside each compartment, which leads to excessive formation of silt deposits.
There are rules for calculating volume for each type of system:
- For drainage pits and simple receptacles: the volume must correspond to the monthly volume of waste with a margin of up to 30%.
- For anaerobic structures with 72-hour treatment: 3 daily volumes with a margin of 25%.
- For stations with 10-day processing: 10 maximum daily volumes with a margin of 25%.
How to avoid system depressurization: defects in case materials
Error: when constructing an autonomous sewer system in areas with aggressive soils or high groundwater levels, standard reinforced concrete, brick or metal welded structures are used.
The optimal material for making the body of sewage tanks is polyethylene, fiberglass and PVC. The materials are absolutely moisture-proof. The walls can withstand prolonged exposure to an aggressive environment. The absence of seams is another advantage. Plastic is not subject to rotting, and the structure of the internal walls does not contribute to the appearance of deposits and plaque.
Plastic can be easily installed in soil with a constant high level of moisture.
When reinforced concrete rings are laid in a pit, then when using prefabricated parts without joints, it is necessary to hermetically seal the seams. If the groundwater level is predominantly high, then the lack of strong adhesion between the rings can cause the tank to flood with groundwater, runoff pouring onto the surface, and horizontal failure of the rings.
Metal containers, despite all the strength of the material, have one significant drawback - welded seams. Even high-quality anti-corrosion treatment cannot guarantee long-term preservation of the integrity of the connections.
Brick should only be used for the construction of filtration tanks. The material is porous; to seal it, you will have to completely plaster the walls with a solution with the addition of insulating additives.
The design has been chosen, the installation location has been determined without errors, all that remains is to install the system correctly and connect the parts correctly. Particular attention should be paid to organizing drainage from an autonomous sewer system.
Main mistakes when connecting a septic tank: improper laying and connection of pipes
Error: when organizing the supply trench, the bottom was not equipped. The pipes are not connected correctly.
Laying a pipe on an unprepared base is fraught with rupture, deformation and loss of tightness in an area with an uneven bottom. The bottom of the trench must be flat, compacted and free of sharp stones. All boulders whose diameter exceeds 30 cm must be removed from the channel.
Laying a branch on a backfill base
If installation is carried out in damp, heavy soil, it makes sense to use concrete trays for laying pipes or a special polystyrene foam shell to protect the parts. In dry soil, it is enough to fill it with sand.
A common mistake is an error in the direction of laying the pipeline. Pipes for external autonomous sewerage are marked with arrows indicating the direction of flow. The socket should be in the direction of the fluid movement. If you connect the pipes in the opposite direction, the couplings will leak.
Uneven base: the reason for system failure
Myth: the base of the pit must be sloped.
Uneven base: the container will be installed skewed
In fact, a slight slope is only needed when installing horizontal drain receivers with one hatch - towards the drainage neck. The slope is formed so that sediment does not accumulate in corners that are difficult to reach for pumping.
All other autonomous sewage systems are installed on a prepared base with a strictly horizontal bottom. Bulk cushions made of gravel and compacted sand are used as a base. To install the stations, the bottom is filled with mortar with reinforcement, or a reinforced concrete floor slab is installed.
Common mistakes in installing plastic structures
Mistake: backfilling an empty container, saving on holding straps.
An autonomous station with a plastic casing is installed using special technology. After checking the horizontal position, the container is secured to a concrete base. For anchoring, canvas or special construction straps are used, which are passed through hooks in the concrete base slab.
Installation of the tank in a prepared pit
After installation, the container must be filled with water. The liquid level should not be lower than 1/3 of the tank volume. If an empty tank is filled in, the walls may deform under the weight of the soil. Following simple rules will allow you to avoid troubles with pushing an empty tank onto the surface of the ground and squeezing the structure.
How not to equip a filter well
Error: The more crushed stone, the better the bottom filter.
In reality, a bulk filter that is too high clogs faster and reduces the flow rate of runoff into the ground.
Backfill level in the filter well
A sufficient layer of crushed stone with sand is from 50 cm to 1 m.
Important! Do not use the fine fraction of bulk materials to create filter layers. Small particles in a humid environment cluster into dense flat plates that block the drain from seeping into the ground. The optimal fraction size is 20 – 40 mm.
Incorrect installation of the pump group
Drainage pumps must not be installed in compartments containing sludge. If stationary placement of the pumping group in tanks for forced pumping of liquid is planned, then a separate compartment must be provided for installation of the equipment.
Use special pumps and compressors without metal parts
The location of the pump in the anaerobic treatment chamber leads to the fact that part of the undissolved sediments and bottom sediments is constantly pumped into the next compartment. As a result, the purity of the effluent at the outlet decreases.
Incorrect organization of system reset
Error: discharge from a septic tank without a biofilter directly into a natural reservoir or onto the terrain.
Correct discharge: to the filtration field
Such an organization of autonomous sewerage is fraught not only with a substantial fine and a ban on the use of sewerage, but also with contamination of the soil and drinking water. Discharge onto terrain and into natural and artificial reservoirs is permitted only from stations with a guaranteed discharge purity of 95%.
When the purity of the wastewater is at the level of 50–70%, additional purification of the water is necessary before discharge. Septic tanks can be discharged into fields, filtration tunnels and wells equipped with a bulk layer.
It is impossible to legalize the use of an ordinary cesspool or drainage basin within the city limits.
In addition to the 13 most common mistakes listed in the construction of autonomous sewage systems, when arranging drainage systems, you have to take into account hundreds of nuances associated with the installation features of different types of systems.
In order not to be faced with the need to reinstall sewer tanks, which is much more expensive than the initial installation, it is better to entrust not only excavation work and installation, but also design to the craftsmen. It is advisable that the entire procedure - from drawing up the scheme to launching - be carried out by one organization. When ordering, ask whether the organization has the manufacturer’s permission to install the purchased factory installation. In case of non-professional connection, warranty service is not provided.
Standardized distances from buildings to the septic tank
The installation of a treatment plant is allowed at a certain distance from a residential building:
- It is necessary to retreat at least 5 m from the foundation of a residential building to the local treatment plant. Such a gap is necessary for reasons of sanitary safety, and also due to the fact that some types of septic tanks give off an unpleasant odor. Modern biological treatment stations guarantee the complete absence of unpleasant odors. In some cases, it is allowed to place a treatment structure closer than five meters from the house.
- You should not install a septic tank at a great distance from the house, since when the pipeline length is more than 15 m, it is necessary to install inspection wells to clear frequent blockages. Also in this case, it is difficult to ensure the required slope of the sewer pipeline to enter it at the required height into the treatment plant.
It is worth knowing: when laying external sewer networks, inspection wells are made for every 15 m of a straight pipeline, as well as at turning points.
Drain pit in a private house: norms and rules of SNiP
If you are planning to install a drainage pit, you need to know that this issue is carefully monitored by sanitary services and legislation.
The reason for this is the potential threat to the environment that this structure poses.
That is why, before starting installation work, you should obtain permission to carry it out.
Country house drainage pit
Popular model: EKODIN 5
recycling 1 cubic m. per day.
Max. dump 250 l.
The process of laying pipes on your own site is almost never checked by anyone. Why? Yes, because it is extremely difficult to control every septic tank installed on private property.
And yet, we do not recommend that you give in to temptation and build an individual treatment system on your own inspiration. Perhaps soon the sanitary-epidemiological service will come to you, and not to your neighbor, to carry out an inspection.
Getting permission
Permission to build a cesspool on the territory adjacent to the house is issued by the local SES.
In order to obtain the necessary document, you will need to draw up a diagram and design of the treatment facility and submit it to this service.
At the same time, the project must fully comply with current sanitary standards and SNiP. Only in this case can it be approved.
Location according to SNiP
After approval, an inspector may come to your private land plot to verify compliance with the project conditions.
If they are violated, in particular, the distance from the cesspool to the neighboring plot is not maintained, you will face a fine, the size of which will depend on the severity of the violation.
That is why it is still better to arrange the drainage pit according to the rules.
Location of the drainage pit from the house
The cost of obtaining a permit will be quite low. It will be approximately 200 rubles.
If you are interested in the question of what the fine is for a cesspool in the absence of permitting documentation for it, then it can vary between 100-500 rubles, reaching several thousand.
List of documents to obtain permission for a septic tank
So, what documents are needed to install a septic tank for the SES to give permission:
- Detailed project or diagram of local sewerage. It should reflect its structure, location, and pipelines.
- Technical passport of the sewerage installation, if used.
- Topological survey of the site.
- Residential building plan.
- Documents confirming ownership of the site and buildings.
- Agreement with companies for the removal of liquid waste.
- Cadastral plan, certificate from the BTI, certificate from energy networks about connecting to electricity, if your private house and plot are located within the city.
An application for a permit to install a septic tank is attached to this package of documents. If the documents are in order and there are no questions about them, they are reviewed within a month.
It is worth noting that after obtaining permission, the septic tank must be installed strictly in accordance with the project. The SES can periodically check both the operation of the septic tank and the rules for its arrangement. There is a fine for a septic tank installed without permission or for independent and uncoordinated changes to the design. Its size is determined individually and depends on the degree of violation, whether it is the first or not. If neighbors filed a complaint, the authorities may limit themselves to a warning; in more complex cases, the amount of the fine is set in court and can reach several thousand rubles.
A septic tank is an excellent engineering structure that can increase the comfort of both permanent housing and seasonal country houses. Treat its device with all responsibility and you can be sure that you will not have problems in the future.
SNiP standards for design
The first regulatory document regulating the construction of a cesspool is SanPiN 42-128-4690-8.
You should also pay attention to the standards prescribed in SNiP 30-02-97.
They provide the following rules for arranging a drainage pit:
Standards SanPiN 42-128-4690-8
- The wastewater storage tank must be located in the area immediately adjacent to a private house;
- the distance from the cesspool to the water supply must be at least 10 meters. A shorter distance to the central water supply will not be approved by the SES. Also, the pit should not be located closer than 20 meters from the well or borehole. This distance between the well and the cesspool must be observed;
- place a storage or treatment facility no closer than 10 meters to your residential building and residential buildings located in the neighboring territory. But the indicator here is not clear. If we talk about the standards for placing cesspools on the site, then in some of their editions it is noted that they can be placed at a distance of 5 meters from the house;
- the distance from the system to the fence delimiting two plots of land should not be less than 2 meters;
- The depth of the cesspool according to SNiP cannot exceed 3 meters. In this case, a distance of 1 meter should remain between the bottom and the groundwater level.
Standard distance SanPiN 42-128-4690-8
There are also additional points that must be observed during the construction and even operation of a cesspool:
Requirements for the drain pit
- the structure must have a sealed cesspool and a ground part. The latter should be tightly closed with a lid;
- it is prohibited to allow the pit to be filled higher than 35 cm from the upper edge of its underground part;
- The cesspool must be cleaned as it fills. The maximum frequency of cleaning is once every six months;
- Be sure to disinfect the cesspool.
Disinfector for cesspool
Additionally, the standards for the location of a cesspool on the site are prescribed in the following documents:
- SNiP 2.04.03-85;
- SNiP 2.04.04-84, as well as SNiP 2.04.01.-85;
- SanPiN 2.1.5.980-90;
- SanPiN 2.2.1/2.1.1.1200-03.
SNiP drainage pit design standards
It should be noted that in all of the listed regulations and sanitary standards, the requirements for cesspools are the same.
That is why you do not have to study large amounts of information in order to obtain the appropriate permission to implement the prepared project.
Acceptable distances from the septic tank to water sources
When choosing a place for a septic tank on a site, it is very important to maintain the required distance to wells or boreholes from which drinking water is supplied to houses. This will protect aquifers from pollution by wastewater.
Important: although modern treatment facilities are durable and sealed structures, the possibility of depressurization or rupture of the pipeline cannot be completely excluded. This can lead to contamination of drinking water and various diseases.
That is why, according to SNiP, the distance from the VOC to the water source is taken depending on the presence of filter soil rocks between groundwater and the soil, which is used for final purification (filtration) of wastewater. Hydrogeological methods are used to determine the composition of soils. This normalized gap can be like this:
Rules for installing a septic tank on the site
- If there is no connection between the soil layers, then the distance from the treatment plant to the septic tank can be at least 20 m.
- If soils with high filtering capacity are found (sandy, loamy or sandy loam), then this distance increases to 50-80 m.
- From open reservoirs with standing water, a distance of at least 30 m is maintained to the septic tank. A gap of 10 m is maintained from rivers and streams.
SNiP standards also regulate the distance from the water supply to the septic tank. This gap must be at least 10 m so that in the event of depressurization of water pipes, wastewater cannot enter the drinking water.
Attention: an equally important requirement that must be observed when choosing a location for a septic tank is that the VOC must be located lower in the slope of the area than the well or well.
How to choose a location
The first stage in creating a project is determining the location of the drainage pit.
It should be located on the lowest part of the land plot, and also be located at a certain distance from the objects located here.
The rules for placing a cesspool on a site strictly determine the distance that must be observed.
Let's consider this issue in detail:
Rules for placing a cesspool on the site
- the distance from the well to the cesspool should not be less than 20 meters. In this case, the pit should be located below the well along the slope of the site. If we talk about the distance from the well to the cesspool, then it will be exactly the same. This will protect drinking water from wastewater contamination. This condition must be observed;
- The minimum distance from the house to the cesspool is 5 meters. But, in order to avoid problems with the SES, it is better to increase it to 10-15 meters;
- the distance from the cesspool to the neighbors: to the fence it should not be less than 2 meters, to a residential building - less than 10-12 meters;
- The drainage pit should be located at a distance of 3 meters from the highway. At the same time, easy access for a sewer truck must be provided to it, allowing for cleaning;
- The drainage pit can be placed at a distance of 1-5 meters from outbuildings. It is better to take a larger distance as a basis in order to avoid destruction of the building due to increased soil moisture;
- the distance to the garden or vegetable garden should be 20-30 meters. This will preserve the ecological purity of the soil and guarantee the safety of the crops and plants growing here.
Placement of a cesspool on the site
These will be the standards for a drainage pit in a private house.
It is not so difficult to follow them and it is necessary to do it.
This way you can avoid unnecessary problems, including those with legislation.
Device options
Today it is possible to install various designs of cesspools for storing and partially processing wastewater. It can be:
- ordinary cesspools;
- engineering systems for accumulation and partial processing and separation of wastewater mass.
Sump pit diagram.
The simplest option, which is provided by the relevant permitting services, is cesspools that do not have an equipped bottom. They are constructed if the daily volume of wastewater discharged from a residential building is no more than 1 m³. Sewage pits are installed below the drinking water level so that the water in the well is not contaminated by wastewater.
When installing a septic tank, various parameters must be taken into account:
- requirements for the location of the pit;
- taking into account the type and properties of the soil at the installation site.
Standards for the location of a septic tank and a well in one area:
- if the site has clay soil, the distance between the well and the septic tank should be 20 m;
- for loam - from 30 m;
- for sandy loam and sandy soil - from 50 m.
If the planned volume of waste per day is more than 1 m³, you will have to abandon the design without a bottom in favor of a concrete or brick pit, a PVC or metal septic tank.
Fines for violations
For any violations of the construction or operation of a cesspool, the legislation of the Russian Federation provides for a fine.
However, its size will depend on the severity of the violation, as well as on the number of previously recorded cases of ignoring regulatory documents.
Diagram of daily waste volume
For example, the standards stipulate that a pit with a filter bottom can only be equipped if the daily volume of wastewater does not exceed 1 m3.
Otherwise, the owner of the land plot faces a fine.
Its size will be determined by the court, because it is in court that the issue of choosing a punishment will be decided.
But it should be understood that this is a serious violation of environmental standards, so the fine can reach several thousand rubles.
Well with filter bottom
If a complaint is received from neighbors and a single violation of the rules for operating a cesspool is discovered, then the owner will first be issued a warning with a strong recommendation to eliminate the problem.
If sanitary standards for the operation of a cesspool continue to be violated, there is a risk of receiving a fine. The maximum fine for a cesspool without a bottom is 500 rubles. (according to the Code of Administrative Offenses of the Russian Federation, Article 6.3. Violation of legislation in the field of ensuring the sanitary and epidemiological well-being of the population).
At the same time, its size may increase, especially in cases where the owner of a private plot ignores warnings and penalties more than once.
It is necessary to monitor the condition of the cesspool
In addition to a fine, which can reach 500 rubles, the court may order the drain to be remodeled, moved, or completely eliminated.
This is relevant in cases where the distance of the cesspool from its neighbors according to SNiP is violated.
In view of this, it is better to initially carry out construction taking into account all norms and distances.

The degree of punishment depends on the guilt. If a person accidentally violates the law, a preliminary warning from the regulatory organization is enough for him.
The sanitary and epidemiological supervision issues a warning, indicating the need to eliminate violations of the rights of other citizens.
There is no answer, the sewer still continues to spill into the garden or into a public ditch, then a fine.
In accordance with Art. 6.3 of the Code of Administrative Offenses of the Russian Federation, the punishment is:
- for individuals 100-500 rubles;
- for officials up to 1000 rubles;
- for entrepreneurs up to 1000 rub. or suspension of the activities of an individual entrepreneur for up to 90 days;
- for legal entities, a fine of 10-20 thousand rubles or suspension of the enterprise’s activities for up to 90 days.
The appeal must be sent to the sanitary and epidemiological control authorities of the city, region or locality. Complaints are accepted by the department of Rospotrebnadzor and SES.

In addition to the central sewerage network and sealed septic tanks, according to the law, waste can be discharged into certain types of toilets.
In particular:
- Chemical toilet. It is a sealed tank into which certain reagents are poured. Requires regular pumping.
- Dry toilet. It also looks like a sealed tank, but biological components, rather than chemicals, are used to decompose waste. Bacteria process waste into safe material within a certain period of time. The result is an organic fertilizer that can be used in the garden.
- Peat toilet. It is a pit with sealed walls and bottom, where human waste products are covered with a layer of peat. To make the decomposition process go faster, the owner adds grass, vegetable peelings and other natural products. Once the pit is full, the contents can be pumped into a compost bin, then the organic matter can be used as fertilizer. To drain liquid, the owners organize a drainage system.
- Electric toilets. These are universal devices that burn fractions. The ash can then be thrown into compost. To drain the liquid, the owner should install a filter drainage.
Expert opinion
Vladislav Ponomarev
Design engineer, inventor
If you install a deep cleaning station in a suburban area, it will clarify and disinfect 95% of the drainage liquid. The resulting water is suitable for household needs - watering, car washing and even summer showers.
If in multi-storey buildings property owners do not think about the question of where to dispose of waste water and sewage, then for owners of private households the problem of waste and sewage disposal requires a permanent solution. They have no choice but to make a drainage hole with their own hands. This option for arranging a treatment plant is the simplest and most affordable when constructing it on your own.
Landscaping of a personal plot begins with the installation of a water supply and sewerage system, since staying in nature cannot be called comfortable if you have to carry drinking water from a well and run to nearby bushes when needed.
There are several options for disposing and processing wastewater and sewage, but the simplest design is a cesspool. It is necessary to have knowledge of how to properly make a drainage pit without the help of specialists, so that in the future you will not have problems with its operation and the environmental situation in the area adjacent to the house.
Types of drainage pits
Despite the simplicity of the design, drainage pits differ in the way they are implemented.
- sealed;
- filtering;
- two-chamber.
The drainage pit is sealed. The process of how to make a drainage pit with a completely sealed body has its own characteristics. This option is the safest from an environmental point of view, since all waste coming from the house or street toilet ends up in a sealed sump and remains there until the arrival of the sewer truck.
When the pit is made airtight, sewage does not contaminate the soil and groundwater. As a result, the ecological system will not be threatened, as will the sources of drinking water. The advantage of such a treatment design is that it can be used regardless of the hydrogeological conditions in the adjacent area.
But there are also disadvantages. Sewage and sewage accumulated in a sealed container must be periodically pumped out, and calling a sewer truck is not a cheap service. The frequency of pumping depends on the volume of the tank used.
Drain filter pit. Of course, not all owners of private houses have the financial condition to order special sewage disposal equipment a large number of times during the year. In this case, you can consider the option of arranging a drain pit without a bottom - a filter (read: “Sewer pit - how to make it yourself”).
In fact, sanitary standards prohibit the construction of a local sewage system of this design: if untreated wastewater gets into the ground, it can cause irreparable harm to the environment in a given area. They can even be a source of contamination of drinking water sources, and this is already extremely dangerous for human health.
This option, if currently used, is only for country houses, since the people living in them require a small amount of water. It is recommended to build filter-type waste pits only if the volume of waste during the day is no more than a cubic meter. When the amount of wastewater is small, it has time to be processed through natural decomposition.
Often pits of this type are installed during the construction of baths, steam rooms and for houses in which separation of wastewater is provided. In the latter case, it is necessary to lay two sewer branches and build two drainage pits on the site. The first of them, equipped with a filter type, receives waste water from the washing machine, shower cabin, and washbasin. These effluents are considered relatively clean.
Sewage from the toilet and water from the kitchen are directed into the second sealed pit.
Two-chamber drain pit. This solution to the waste disposal problem is considered practical and reasonable.
The operating principle of this treatment plant, shown in the photo, is as follows:
- a drainage pit, consisting of two chambers, is connected at the top by an overflow, the first of which is sealed, and the second is filtering;
- unseparated wastewater initially enters the first of the chambers, which is sealed, and settles there (mechanically separated);
- solid particles sink down to the bottom, and less contaminated water flows into the next chamber;
- from another chamber, water is filtered into the soil;
- The waste collected in the first chamber must be pumped out from time to time. To reduce the amount of waste, special biological preparations are used. The bacterial strains contained in them promote the processing of organic matter, which leads to a reduction in the amount of sewage.
Before making a drainage hole in a private house, you need to design a construction plan. It is necessary to select the type of structure, location of construction and calculate the required volume of the tank.
Determining the volume of the drain pit
Vegetable garden, garden, balcony
A wooden shed on the edge of the plot, a window with a “heart”, a hole without a bottom and an indescribable aroma – is this a familiar picture? In most old dachas, the toilet is organized in this way. Is this legal, and what does this approach to ecology threaten for summer residents?
Not all small settlements can boast of having a central sewer system, let alone holiday villages.
However, its absence is not a reason for land pollution with human waste. How to properly build a toilet on a site so as not to harm the soil and not receive very significant penalties?
Where should the toilet be on the site?
A country toilet, even the most modern one and built in accordance with the architectural style of the site, is by no means the place that they want to bring to the fore. Ideally, it is pushed into the far corner of the garden and fenced off with trees and shrubs. But the problem is - what to do if in the same corner your neighbors have a well, garden beds or a playground?
According to SNiP 30-02-97, the toilet should be located at a distance of 12 m from residential buildings, cellars and playgrounds, 8 m from wells and other sources of drinking water, 1 m from the fence.
The distance is considered not only from your own buildings, but also from neighboring ones.
Obtaining permission to install a septic tank
A septic tank is a device that poses a potential threat to the environmental situation. That is why the uncontrolled construction of such structures is prohibited. Before installing a treatment plant, it is necessary to develop a project, coordinate the location of the septic tank on the site with the SES and obtain a construction permit.

Installation of septic tanks and sanitary standards
In this case, you will receive permission to install on your site only if the project complies with the requirements of SNiP and SanPiN. The most important point in the project is the placement of the treatment plant in a suburban area.
Attention: after receiving approval from the SES, the installation and location of the septic tank on the site must be carried out exactly in accordance with the project. It is possible that regulatory authorities will check the constructed treatment plant for compliance with the design.
Options for country toilets
According to paragraph 8.7 of SNiP 30-02-97, in the absence of a central sewerage system, the owner of the site can choose one of 3 options:
• dry closet;
• powder closet (peat toilet);
• backlash closet (outdoor toilet with a sealed cesspool).
The latter option requires approval from the SES at the construction planning stage.
Liquid dry toilet in the country
The easiest way to install a dry closet is with a ready-made container and cubicle. Of course, its maintenance will not be so cheap - the stock of “chemicals” will have to be constantly updated, and it will only be suitable for a small family for a seasonal stay at the dacha.
Although a liquid toilet does a good job of eliminating unpleasant odors, it can only be used in the warm season or indoors, so it is not suitable for year-round outdoor use. Dry toilets are sealed, so they can be placed in any part of the site.
Peat toilet in the country
Powder closets in dachas are also quite common, if only because they are cheaper to use than bio-type ones, and the waste from them is also suitable for composting.
Peat toilets also use sealed containers, although peat or sawdust is stored on top (in place of the flush tank in more complex designs, or in a separate bucket in cheap options). They are poured into waste, and the resulting substance is taken to a compost pit and spilled with preparations such as Biocompostin, Baikal, Vozrozhdenie, Siyanie or their analogues.
Backlash closet at the dacha
The largest possible construction is a backlash closet. It is a separate building with a sealed concrete pit, an exhaust hood and a ventilation system. A sewage disposal machine must pump out waste from the backlash closet; it can be used all year round.
None of the permitted types of toilets allow waste to enter soil and water.

Illegal disposal of waste liquids can lead to environmental pollution. Sewage will enter the soil and through underground sources into tap water. And this threatens epidemic outbreaks of intestinal infections. Sometimes residents of private houses ignore waste disposal rules. But if you know what to do if a neighbor drains sewerage onto the street or onto your property, you can bring him to his senses and protect yourself and your loved ones.
It is illegal to dump raw sewage into ditches.
Human waste must be thoroughly cleaned before being disposed of in soil or water bodies.
Only clarified wastewater that has reached biological and physicochemical standards is allowed to be discharged. They are established by sanitary and hygienic rules. The liquid should not contain harmful, toxic or health-hazardous impurities.
Particular attention is paid to bacterial indicators in relation to household wastewater.
If there is a cesspool or a sealed septic tank, it is necessary to periodically pump out the contents of the tank using sewage equipment. Its owners enter into agreements with organizations that supervise local wastewater treatment plants, where the pumped-out feces are transported. But there are other ways to dispose of autonomous sewage waste. They depend on the design features of the drainage system.
Peat toilet
Waste products are layered with peat, and when the compartment is full, the contents are transferred to a compost pit. It is supplemented with grass, vegetable and fruit peelings, and other biodegradable ingredients. As a result, the organic matter rots, and after a season an excellent fertilizer for the garden and vegetable garden matures.
To increase the performance of such amenities, a drain hose is attached to them to drain excess liquid. It will not be aggressive because it has already been cleaned through a peat filter.
Chemical toilet
Getting rid of content here is more difficult. The reagents poured into the receiving tank are chemically active. The contents of the toilet will not compost; it will rather harm the soil. Therefore, the waste is poured into a sealed tank, and vacuum cleaners are called in to pump it out. The advantage over raking here is that the help of specialists is required much less frequently.
Dry toilet
A simple device into which you need to pour or fill biological products with cleaning microorganisms produces an environmentally safe substrate. Bacteria process the contents of the storage tank into organic fertilizer, which can be put into a compost heap or even mixed with soil and used to create beds. If you have a vegetable garden on your personal plot, there will be no problems with waste disposal.
The only problem is the constant purchase and replenishment of biomaterial, since the colonies of microorganisms need to be renewed.
Dry toilets equipped with cassettes are convenient. These are sealed containers filled with liquid that converts feces into an environmentally friendly substrate. The device is equipped with an indicator that shows that it is time to replace the cassette with a new one.
If it is possible to purchase filler, the old cassette is washed and reinstalled. The contents can also be dumped into a compost bin. The only disadvantage of such devices is that you need to be careful when removing the cassette.
If handled carelessly, it can leak and emit a stench.
When using such devices, solid fractions are dried and burned, leaving a small amount of ash. It can be composted. The problem arises with draining the liquid. To do this, it is necessary to equip a filter drainage system.
If a deep cleaning station is installed in the local area, which is capable of clarifying wastewater up to 95–98 percent, the drain liquid turns into water for domestic needs. You can use it to wash your car, water your garden, and even use it for a summer shower.
Peat toilet Cassette dry toilet Chemical toilet Electric toilet
Illegal residents of country houses are capable of leading a sewer pipe into a storm drain or even into a neighbor's garden. Of course, those around you are not delighted with this. But the problem here is not only an unpleasant odor. This attitude towards wastewater is dangerous for the environment and the health of people and animals.
First of all, you need to talk to the person causing the problem. Perhaps he does not specifically drain the waste, but, for example, his septic tank burst. But such cases are extremely rare, and violators usually ignore those around them. We have to take tough measures.
You should first of all complain to the authorities that control the sanitary and hygienic condition of populated areas if your neighbors drain sewage into your garden or storm drain. This may be the local branch of Rospotrebnadzor or SES. You must submit a written application there in two copies, one of which must be endorsed and given to you.
When applying you must:
- list the problems encountered;
- indicate evidence of unsanitary conditions;
- report a threat to human health and the environment.
It’s good if not only you, but also all the residents of the street complain. The more requests, the faster Rospotrebnadzor specialists will come with an inspection.
They will take samples of the water in the storm drain or the soil at the site where the sewage waste ends up and draw up a report.
This document will be needed if the order of the sanitary authorities to eliminate violations is ignored, and in order to punish your neighbors for draining sewage onto your garden plot, you will have to go to court.
Additionally, you can file a complaint with the district prosecutor's office, focusing on the threat to health safety. Employees of this body will have to conduct an investigation and prohibit the dumping of waste in public places or on someone else's territory.
Sanitary, hygienic and environmental regulations stipulate the rules for the collection, accumulation, transportation, and disposal of waste. If they are violated, the perpetrators are subject to administrative punishment.
The main document according to which the fine for draining sewerage in a private house is determined is the Code of Administrative Offenses of the Russian Federation. Article 8.2 of the Code of Administrative Offenses details how violators of environmental and sanitary requirements are punished.
Penalties for illegal discharge of wastewater include:
- for individuals – from 1000 to 2000 rubles;
- for officials - from 10,000 to 30,000 rubles;
- for individual entrepreneurs – from 30,000 to 50,000 rubles;
- for enterprises - from 100,000 to 250,000 rubles.
The violating company will also be forced to suspend operations for up to 90 days. Penalties may be issued repeatedly until the problems are corrected.
If violations lead to illness or even death of people, criminal penalties apply to the perpetrators.
Standards for installing septic tanks on site
If, in the absence of a central sewerage system, you choose to install a septic tank, then you also have to comply with many requirements for the placement and installation of this unit.
When choosing a place on the site where you can install a septic tank, you should remember that:
• the distance from the septic tank to the foundation of the house must be at least 5 m;
• the distance from the septic tank to the road must be at least 5 m;
• the distance from the septic tank to the gas pipe must be at least 5 m;
• the distance between the water supply pipes and the sewerage system must be more than 10 m, and the septic tank must be located lower so that in the event of a pipe break, waste does not get into the water;
• the distance from the septic tank to the fence must be at least 2 m, and its placement must be agreed in advance with the neighbors so that the septic tank does not end up next to important objects for their development and maintenance;
• the distance from the septic tank to the well, water intake well should be 30-50 m, to the lake or river - 10 m, to the reservoir - 30 m;
• the distance from the septic tank to the foundations of outbuildings must be at least 1 m;
• trees should be 3-4 m from the septic tank, bushes – 1 m;
• the pipe slope should be 20 mm per linear meter, while it is undesirable to remove the septic tank further than 10-15 m from the house, since it will be difficult to ensure cleaning and maintenance of the pipes without creating additional wells;
• access to the septic tank hatch must be provided for a sewer truck.
It is almost impossible to comply with these standards on a standard summer cottage, but owners of private houses with areas larger than 10-12 acres can fit into the requirements, although they will have to struggle a lot with the layout.
Expert advice
For the external sewer system of a private house, sealed septic tanks are recommended, which are not only more convenient to use, but are also highly reliable. They are usually installed by specialized stations. SanPiNs for them are as follows:
Sewerage diagram for a country house.
- During installation, the bottom of the pit should be inclined towards the service hatch, which is necessary for subsequent maintenance;
- the installation location is selected in such a way that the septic tank is located about 10 m from the residential building, and 1 m from the fence of the site;
- a sealed cesspool requires periodic cleaning with a special sewage disposal machine.
It is worth paying attention to a number of tips given by experts:
- for the access of special equipment it is necessary to provide a spacious and convenient place, so there is no need to hide the septic tank in the far corner of the site;
- During operation of the tank, methane may form, so it is recommended to equip the tank with a special ventilation system. According to the requirements of the sanitary and epidemiological station, it will be necessary to provide a ventilation pipe with a diameter of 10 cm. The height of the pipe above ground level should be 60 cm.
Communications supply
Scheme of the location of the cesspool relative to other objects.
A sanitary permit will have to be obtained not only for the installation of septic tanks, but also for all utilities that are located nearby. There are certain standards for the placement of pipes on the site:
- reinforced concrete and asbestos-cement pipes must be located at a distance of 5 m or more from the septic tank;
- cast iron pipelines with a diameter of up to 200 mm must be located at a distance of 1.5 m from the wastewater sump;
- cast iron pipelines with a diameter of 200 mm or more can be located at a distance of at least 3 m from the septic tank;
- gas pipes can be located at a distance of 5 m from the location of the septic tanks.

When installing a septic tank on a personal plot, you must remember to comply with all sanitary standards and obtain the appropriate permit. Sanitary standards regulate the location of the septic tank and establish minimum distances for laying other communications on the site. Taking into account the SES and installation of the septic tank relative to the location of the residential building and other buildings. It is worth being prepared for periodic inspections by employees of the sanitary and epidemiological station. But you should not be categorical about this, since all this is done for the safety of you and others.
Fines for improper design and placement of a toilet
Despite the fact that standards for the construction of toilets in dachas and villages are rarely checked, the law provides for fines for violating them. They are regulated by SanPiN 42-128-4690-88 “Sanitary rules for the maintenance of territories of populated areas”, according to which the owner of a site can receive a one-time fine of 3,000 to 5,000 rubles for failure to comply with a number of standards.
To avoid being fined, the following rules must be observed when constructing and using a toilet on site:
• the cesspool must be sealed;
• the depth of the cesspool should not exceed 3 m;
• the cesspool should not reach groundwater;
• cleaning of the container must be done at least once every six months, or every time when less than 350 mm remains to be filled;
• water from septic tanks must go through all stages of purification.
If at least one of these requirements is violated, local authorities may invite representatives of Rospotrebnadzor or the Sanitary Epidemiological Station and draw up a violation report, as a result of which you will receive a fine, which will be repeated every six months until the violations are eliminated.
Are you sure that they won’t come to fine you, because “everyone builds like this” and “it’s been like this for a hundred years - and nothing”? Remember that once everything happens for the first time, and it will be unpleasant to start the summer season with unnecessary expenses and bureaucratic fuss.

Why can't you install a septic tank without a bottom? Do-it-yourself high-quality septic tank
There is an opinion that it used to be like, they dug a hole in the garden, built a wooden toilet on top and used it for years, plus fertilizers and no harm. That’s right, and you can call it a compost pit, but you just need to take into account one thing – this “structure” did not have that much water and chemical compounds poured into it.
The whole point is this, because in such a septic tank in modern realities, water entering in large quantities, dissolving biomass that did not have time to decompose - go through the composting process, enters the soil layers, and then penetrates into the aquifers.
This is called infiltration, this is a very, very dangerous phenomenon, it carries with it a bouquet of microbes that are dangerous to the human - especially children's body, complex microbiological compounds - hazardous to health, and of course odors. And therefore, if you understand this, but the neighbor who arranged his sewer system in this way does not understand this, then it is worth talking to him about it.
Because it can affect you directly and your neighbors in the form of an unpleasant odor from the well, or a hidden danger in the form of dangerous microbes and, as a result, sudden illnesses. But in this case, it is not worth calling the SES immediately, because with a 99% probability, the subject will be issued a very impressive fine from 50,000 to 100,000 rubles. with an order to dismantle this structure. Therefore, it is better to first try to explain in words, and try to convince to modernize the old septic tank to the standards of the corresponding SNiP.
Let's consider the following scenario: a conscientious owner independently made a sewerage design that complies with SanPiN, or simply made a sealed cesspool, or used the services of contractors, and as a result successfully started the sewerage system in his house. But due to poor environmental conditions or simply based on a neighbor’s complaint about poor-quality water, the SES will go to the area and make a “raid” on private households and require documents confirming the tightness or compliance with the MAC (maximum permissible concentration) standards for your septic tank. And if you do not have any document in your hands at this moment, then you are unlikely to be able to take it anywhere - even for a fee. No one will want to take responsibility for you, because this entails serious consequences, an impressive fine and an order to dismantle structures.
So is it possible to make a sewer system in the house with your own hands?
Of course you can! This way you can save your construction budget and get a good result. You just need to be guided by working diagrams for installing an autonomous sewer system, or a cesspool, and be sure to have documents confirming this, for example, a passport for a septic tank and a certificate. The first thing you need to pay attention to is the tightness of the concrete and ease of construction. After all, the time saved during the installation of a septic tank will reduce the cost of equipment. Remember that not all concrete is airtight, but only special grades of concrete with hydraulic additives.
You also need to take into account the composition of the soil, landscape features - terrain slope, groundwater level, etc., if you do not have such skills, then it is better to talk with professionals in this matter, ask more questions. Talk to your neighbors about who has which septic tank installed and how it works in different seasonal periods. Pay attention to how water in your or neighboring areas is absorbed into the soil - for example, after rain. How long have the puddles been standing, study the landscape, determine the movement of groundwater - this can be determined by the slope of the landscape.
With the products of our company you can solve the issue of sewerage - installing a septic tank in your home. All our septic tanks have a monolithic base and technological holes. They are made only using high grade hydraulic concrete. Our septic tanks operate completely autonomously - without electricity and are very easy to maintain.
