The distance between the sewer well and the neighboring plot. What should be the distance from the septic tank to the well. Distance to other objects

The arrangement of water supply or sewerage in a private area requires a careful and measured approach. Especially the distance between the sewer wells and the installation of a drainage system from the house. If you do not follow the rules prescribed in SNIP 2.04.03-85, this threatens to pollute water supply sources through the ground, failure of the foundation of a house or any other structure, as well as disruption of the water supply and sewerage due to clogged pipes and the inability to provide proper repairs.

When installing pipes for water supply and sewerage of a private house, it is necessary, firstly, to take into account all topographical factors that can affect the efficiency of communication. These are:

• All types soil in the assigned area;
• The possibility and risk of stumbling upon a quicksand when installing a drainage well;
• The presence on the site or near it of a neighboring source of water supply (well, well, etc.);

Important: if you take into account the listed factors, the installation of sewer pipes near the house will be carried out in accordance with all the rules of SNIP.

Simple sewerage device

According to SNIP, the arrangement of the simplest straight collector near the house should take place provided that the receiving well is located at a minimum distance of 5 meters from the house and other buildings. Ideally, if the distance is increased to 12 meters.

In this case, the pipes must be located in a straight line without bends and turns at a slope towards the septic tank. The slope level must be an acceptable value and be at least 1 cm per 1 meter of pipe.

In such a well, settled water will drain into the ground through drainage, and the remaining particles of decomposed effluents must be pumped out using a sewer.

The device of the sewerage on a site with a problem relief

According to the rules of SNIP, the installation of a sewer collector with a complex configuration must be carried out according to the following rules:

• When using pipes of 100 mm diameter, the distance from the well to the well should be 15 meters.
• The maximum distance between sewer wells is regulated depending on the diameter of the pipes (assuming a straight collector). So, with pipes d = 150 mm, the distance between the wells can be 35 meters. This segment is considered optimal for effective work collector and its maintenance.
• If there is an arrangement complex collector mass purpose, then according to the rules of SNIP, the distance between the manholes can be increased up to 75 meters.

Important: the parameters described in SNIP apply only to collectors located in a straight line. Moreover, an increase in the diameter of pipes in a private area should be carried out only if absolutely all drains pass through the collector - storm, household, ground, etc.

Sewerage device with drops and turns

If the sewer collector has a complex configuration and many turns, then inspection rotary wells must be installed at the knees. Since it is these places that are the risk zone for the effective operation of the sewer, access to them must be year-round.

According to SNIP, the distances between rotary wells are not regulated. The number of rotary wells directly depends on the number of collector bends at right angles.

If we are talking about the complex terrain of the site, which goes down a large slope, then according to the SNIP, it is necessary to install differential wells, which must be mandatory. Thanks to such reservoirs, the speed Wastewater will be reduced, which means that the entire sewerage system will be protected from sedimentation of sewage sludge, which can move at high speed under a large slope. This is absolutely impossible to avoid in order to avoid blockages in the collector.

According to SNIP, when installing drop wells, the following requirements must be met:

• The total height in the case of one drop should not be more than three meters;
• If the drop is minimal and its height does not exceed 0.5 meters, and subject to the use of pipes, d of which is 600 mm, the drop-type tanks can be replaced with viewing tanks, but subject to the presence of a drain. But it is known that when arranging sewerage in a private area, pipes of 100 mm diameter are mainly used, so the installation of an overflow tank cannot be avoided.

Important: if you find it difficult to independently develop a plan for the location of the sewer collector, taking into account all the rules, then it may be better to invite specialists who will draw up correct scheme pipeline installation.

endure minimum distance from the house to the well is not an easy task for an inexperienced developer trying to avoid possible troubles due to non-compliance with the norms of SanPiN and SNiP. Even on large household plots, it is not always possible to comply with all the required standards, and the choice of a place for a well turns out to be difficult decision for the skilled engineer. Lack of centralized water supply and sewerage at the present level construction industry can be easily compensated by technological facilities. But on suburban area standard size the distance between the well and other objects is sometimes impossible to maintain.

Well next to a house

Criteria and requirements

Define required distance from the well to the house you need at the very beginning of the development of your own land ownership. Without careful consideration of the placement of sanitary facilities on the site, it is impossible to start laying the foundation of the house.

On the site in SNT

After all, it is from him and from the distance between cesspool and the toilet depends on how the SanPiN norms will be observed. And in order to avoid future disagreements with neighbors and fines from the sanitary inspection, they are placed on a scheme drawn up taking into account all existing conditions and compliance with requirements and standards. For this you need to know:

1. The installation of a septic tank at the IZHS or SNT site is the only aspect that the Code of Administrative Offenses and the Urban Planning Code deals with, but these are far from all the regulatory documents on sources of water supply and disposal of natural waste. The construction of a cesspool, septic tank, toilet and water supply on the site cannot be started without obtaining permission from the SES. Those options that are considered not quite safe can be checked later.
2. According to SNiP 30-02-97, as amended for 2018, for construction on our own land plot appropriate permission is required. Acting in accordance with the law, which came into force in January 2019, a person simultaneously receives professional expertise on the correct placement of objects on land. The conditions for compliance with the norms of SNiP and categorical (in the case of the deployment of sanitary facilities) requirements of SanPiN are the main criterion that is considered by the supervisory authority when issuing permits for construction.
3. The device of any water supply option (in the absence of a centralized one) assumes a location at a proper distance from the house, septic tank or toilet. Also, it must have an appropriate distance from the fence and similar objects of neighbors. Therefore, in order to begin the development of the available area, it is recommended to first determine the sources of drinking water and the potential for contamination that are potentially dangerous for them. The distance between the well and the neighbors' house in this case is checked much less frequently than the distance from the well shafts and neighboring septic tanks with toilets.
4. SP 53.13330.2011 “Planning and development of territories of horticultural (dacha) associations of citizens. Buildings and Structures” is the basic guide for determining distances on a plan when it comes to the development of construction projects. But this is not the only normative document to which attention should be paid.
5. For planning on the personal allotment of the owner of sanitary buildings, there are other rules that you need to focus on. This is SP 31.13330.2012 (formerly SNiP 2.04.03-85) “Sewerage. External networks and structures "and sanitation standards recorded in SanPiN.

A septic tank is a local treatment plant, which is usually equipped on the territory of private houses for the treatment of domestic wastewater. This design is necessary for those who do not have the opportunity to connect to the central sewer system. But it is important to know that a septic tank cannot be built where it pleases - there are a number of specific requirements that are important to consider before materials are purchased for the construction of a local sewer. One of the main ones is a certain distance from the septic tank to the house. What should it be?

Is it possible to put a septic tank near the house

Why can't you build a septic tank closer than it should be?

Before we find out at what distance from the house an autonomous one should be located, let's find out why quite serious requirements are imposed on her and her location.

The fact is that all the drains that enter the septic tank from a residential building contain all kinds of poisonous and dangerous substances. It is also a variety of bacteria and microorganisms. In general, wastewater contains an explosive mixture of human waste, food residues, surfactants and much more. Just imagine that such a saturated substance in in large numbers gets into clean soil or groundwater - this can lead to dangerous pollution environment.

Sewage from a septic tank, if it leaks, can harm the environment, negatively affecting animals and plants living around. Getting into groundwater, runoff from the local sewage system pollutes them. And there are no guarantees that they will not fall into the exact reservoir from which you or your neighbors pump water in case of drinking water from a well. It is a mistake to assume that effluents are exclusively useful organic fertilizers.

Attention! Drinking water from a water intake poisoned by sewage is not safe for life. Such water can cause the development of various serious diseases.

1. Leakage of the septic tank and, as a result, the ingress of sewage into the ground.
2. Untimely cleaning of the septic tank or floods can lead to overflow of wastewater over the edge of the sewage treatment plant and to contamination of the site.
3. Penetration of sewage into groundwater and its pollution.
4. Flooding of buildings, roads.
5. An unpleasant smell that will spread for a couple of tens of meters around in case of an improperly equipped septic tank.

Some may begin to argue and say that before, in general, everyone used only cesspools and no one thought about the dangers of sewage. But before, such an amount did not get into the sewage chemical substances and water consumption was much less. Because even 20 years ago special significance compliance with sanitary standards regarding private sewer systems was not attached. Now, in every private house, wastewater must either be accumulated and pumped out, or cleaned before entering the environment.

Of course, a home septic tank does not purify water by 100% - only industrial ones are capable of this. treatment facilities(such as), but at least it will allow you to remove the most dangerous suspensions from the water.

Attention! In the event of complaints about the operation of your septic tank, you may face either administrative or criminal penalties.

Installation of a septic tank

Regulations

Since septic tanks are potentially dangerous structures for the well-being of the ecological situation at a particular site, their installation and installation are regulated by several laws, rules, regulations, the requirements of which must be strictly followed. Otherwise, under some unforeseen circumstances, problems with the law cannot be avoided. What is

Table. The main regulatory documents that regulate the construction of local sewerage.

Also, each septic tank project must be submitted to the sanitary service, where a decision will be made on whether it can be implemented in practice or not. Simply put, before starting construction, you need to obtain permission to do so.

Attention! It is necessary to obtain a building permit for a septic tank. Otherwise, the treatment plant will be considered illegal, which may entail the imposition of a rather large fine, the dismantling of sewers, and more.

At the same time, SES specialists can come to you with a check, based only on someone else's complaint.

If you want to provide yourself with amenities and do not want problems with the law, then building a septic tank is not only possible, but also necessary. It is this design that will ensure the preservation of a favorable environmental situation on your land and its surrounding territories.

It is important that waste does not enter the soil

The distance from the septic tank to the house according to the norms

If we turn to the regulatory documents, we will be able to find out that the septic tank relative to the residential building should not be located closer than 5 meters from the foundation. It is this distance that allows you not to feel the “ambre” from the sewer in the room (provided that the structure is well-groomed and works properly). At the same time, it is the filter well that should be located at this distance, if one is planned in the system. sewer facility, since the water coming out of it can begin to wash away the foundation and destroy it. The sedimentation tanks themselves may be closer, but still it’s not worth the risk by arranging them under the windows. To , you can read in our article.

Distance from the septic tank to the house and other objects

Sometimes homeowners try to immediately install a septic tank as far from the house as possible, maintaining a distance of 10-15 m between them. However, it is important to remember that blockages can sometimes occur in sewer pipes, which means they (pipes) will need cleaning. In this case, the natural slope of the pipeline should be 20 mm per linear meter. If it is too large or, on the contrary, small, then blockages cannot be avoided, and with a pipe length of more than 5-8 m, they happen very often. So exactly the recommended 5 m is best option the distance between the treatment plant and the residential building.

In certain cases, the septic tank can be equipped at a distance closer than 5 meters, or directly under the house. But this is only feasible if local wastewater treatment is used.

Distance to other objects

When equipping a septic tank on the site, it is important to take into account the distance between other objects and the treatment plant. For example, it is important to remember that neighbors live next to you. Obviously, you should not install a septic tank under their noses - the structure should be at least 2 m from the neighbor's fence. Be sure to coordinate the installation project of the sewer facility with the neighbors so that there are no complaints in the future.

Also, do not have autonomous sewerage next to the garden - not all plants like a lot of moisture. The distance between the trees and the septic tank should not be less than 4 m, but it can be removed from the bushes by only 1 m.

It is also important to consider the distance between sewer system and a water intake point on the site. If you focus on the rules and regulations, then it is impossible to build a septic tank closer than 30 m relative to the water source. And then this is allowed only on the condition that the water intake is higher if you move along the flow of wastewater. A hydrogeological study of the area will help determine this. And provided that personal plot sandy soils, the minimum distance is 50 m. In general, the farther the septic tank is from the water intake point, the better.

It must be at least 3-5 m (the first indicator applies only to cast-iron conduits). From gas pipe the structure is also removed by 5 m.

On a note! Do not be negligent about the arrangement of the septic tank and its tightness. The entry of contaminants into aquifer ground water fraught with poisoning, the development of diseases in you and your neighbors.

The septic tank is also being built taking into account the location highways. The distance to them from the treatment plant should not be less than 5 m. Otherwise, due to the vibration generated from constantly moving vehicles, the walls of the structure will gradually collapse, which will shorten its service life and may lead to runoff entering groundwater.

Do not forget that with respect to streams, rivers, lakes, the septic tank should also be located at a certain distance - it should be at least 10 m.

Other requirements

When arranging and operating a septic tank, other equally important rules are also taken into account.

1. If groundwater is located high enough, then the arrangement of the septic tank must be taken very carefully. And maybe it's better to abandon it altogether.
2. When planning the installation of a structure, it is important to consider that the septic tank septic tanks periodically need to be cleaned of silt and particulate matter, therefore, a vacuum cleaner car should calmly drive up to them.

Remember that initially correct installation A septic tank will save you nerves and money.

How to choose the location of the septic tank

Finding out at least the approximate location of the septic tank and the possibility of installing it is quite simple and it is quite possible to do it yourself.

Step 1. Make a plan-scheme of all objects located on your site. Be sure to indicate the dimensions and dimensions of buildings, distances to water intake points. Put on the scheme of the territory with plantations, a neighbor's fence, roads and other objects.

Step 2 According to the above data (distances to objects), find out the area on which a septic tank can be installed. The blue rectangle in the figure is the same territory.

Step 3 Determine where the treatment system will be located, and where the filtration well.

Step 4 Find out if any communications pass near the planned location of the septic tank.

What to do if there is not enough space

Unfortunately, it also happens that, whatever one may say, there is no place for installing a septic tank on the site. The area is so small that there will not be enough space for the construction of sewerage according to the rules and regulations. Many people ignore this moment and equip the septic tank anyway, but this should never be done. If it is still not clear why, then you should re-read the information above.

However, the problem with sewerage can be solved even on humble plots. Sometimes it is only necessary to install a drive - a kind of septic tank, reminiscent of. This is a container with a completely sealed bottom and walls. Such a storage tank needs to be emptied as it accumulates, which vacuum trucks do an excellent job of. In addition, the price of this design is quite affordable. But in operation it is no longer the cheapest.

Video - Distance from the septic tank to the foundation

As you can see, building a septic tank is not so easy - it is important to take into account a lot of aspects and nuances. And it does not matter if you cannot build a sewer on the site due to objective reasons. Remember - there is always a way out. But sometimes going against the law and building a septic tank is not worth it - just think that if the septic tank is destroyed (and this will inevitably happen due to the wrong location), the drains will pollute the environment. Remember this and do not break the laws, equip treatment facilities in accordance with all the rules.

The distance from the well to the toilet, its permissible limits, the requirements of SNiP and sanitary and hygienic standards on this issue - this is the whole problem facing every developer. This is a perfectly understandable requirement. Supervisory authorities especially carefully check the distances from the well to outdoor toilet and . Its non-compliance can easily lead to contamination of the source of drinking water, soil for crops, the emergence and development of infectious diseases.

Regulatory documents

Sanitary standards focused on the maximum distancing of the toilet not only from the well, but also from other sources of water supply, building objects on the owner's site and buildings on neighboring plots. The distance from the toilet is regulated by several regulatory and legal acts at once:

• SP 42.13330.2011 Urban planning. Planning and development of urban and rural settlements”;
• adopted ten years later, due to the increased need, SNiP, called: "Planning and development of territories for low-rise housing construction";
• approved two years before it, in February, SNiP entitled “Planning and building gardening (country) associations of citizens. Buildings and constructions";
• sanitary and hygienic standards;
• The Code of Administrative Offenses, in which there is a special subsection 8.6, which defines the requirements for the construction of a closet that exist to this day.

Beautiful wooden structure

What are the standards for?

In 2001, another set of norms and rules was approved for use, called "Single-apartment residential houses." The need for such a number of regulations and standards is dictated by the need to provide for all necessary nuances housing construction.

They provide for several goals at once - the prevention of an epidemic threat and the observance of sanitation and hygiene standards, fire safety and the absence of threatening circumstances for those living in the territory.

The importance of regulatory documents on the issue of how far it is possible and should place the objects necessary for life activity also lies in the observance of the rights of both parties, between the sections of which there is only a demarcation structure.

After all, any attempt to violate existing norms- this is not just disobedience to existing restrictions, but also infringement of the legal rights of people living in the neighborhood.

Compliance with the rules allows you to avoid conflicts with neighbors and administrative violations. The former can lead to the consideration of lawsuits, the destruction of already constructed buildings or fines by regulatory authorities. Administrative violations are subject to different kinds repressive measures, which are defined by the relevant articles.

Territory of a private house

Types of toilets on the land

According to the above regulations, the distance to the well can be at least 25 meters, provided that the toilet is not equipped with a central sewer. In this case, it must be remembered that there must be at least 12 m.

Read also The location of the septic tank on the site: installation standards and placement rules

However, SNiP 30-02-97, as amended in 2018, says that the minimum distance can be 8 m, provided that the well is of a certain type and complies with the standards for its construction.

Scheme of distances between buildings according to SNiP

In the absence of a central sewage system, the problem of a latrine is especially acute, since it is one of the most necessary types of construction, along with a residential building and a source of drinking water. The developer, deprived of the most basic amenities, is forced to independently resolve the problem with the well and toilet.

It is often necessary to engage in a well for the extraction of groundwater, which must be sufficiently removed from the surface. At the same time, decide where and what to put, combining the problems of how to maintain the prescribed distance and coordinate it with the tiny size of the land plot.

Main differences

For summer cottages standard size and small, to accommodate an individual residential building, such requirements are sometimes simply not feasible. To resolve them, one has to resort to different types wells and street toilets.

Most often used:

1. Backlash closet, a capital structure, the emptying of which is carried out with the help of a sewer machine. The purpose of such a building is the maximum isolation of odors, pollution, the exclusion of penetration into the soil and infection by its decay products, toxins, and pathogens. The cabin is certainly equipped with ventilation, the drain is galvanized iron or cast iron. With the high cost of such a toilet, the likelihood of penetration into the soil is practically impossible, because the cesspool is completely sealed.
2. Powder closet, with a special tank, can even be installed indoors, because after each emptying, its contents are poured with a special filler (sawdust or peat). The tank is emptied by hand and formed into a compost heap, which after a year is suitable for fertilizing the site in the form of loose compost.
3. The easiest way is to put a "birdhouse" in the country. Its service life is not very long, but up to 9 years it can stand in the country. And in the villages, a hole is dug in every 4 years and the toilet is moved to another place. A "birdhouse" can be built beautiful and comfortable and even equipped with a toilet bowl. But this is on condition that it will stand in a place where feces will not threaten the surrounding soil, the source of drinking water and neighboring properties.

Minimum distances between objects in SNT and IZHS

To do this, you need to decide on the installation rules and follow them in compliance with all necessary requirements.

SNiP 30-02-97* “Planning and development of horticultural (dacha) associations of citizens. Buildings and structures" determines the following distances to the latrine and cellar - 12 m, from the bathhouse, sauna and well to the lavatory - 8 m.

Distance from the well drinking water determined according to other criteria, but they also take into account the indispensable principle of compliance with sanitary standards (SanPiN), SNiP and other normative documents. And they agree on several points.

Need to take into account

SNiP 30-02-97 * reserves the right for the owner in the absence of sewerage to make conscious choice between three types of toilets: bio, backlash-closet or powder-closet. At the same time, for the construction of a backlash closet, as an outdoor hermetic, equipped with a cesspool of a hermetic type, special coordination with the sanitary and epidemiological service is required and planning of a place for it is still on the very initial stage buildings.

Distance scheme according to SanPiN

Features of the dry closet

Dry closet - not the best a budget option, because it constantly requires chemicals, and besides, it is unlikely to be suitable for big family. But you do not need to mess with the installation - a ready-made booth and capacity are purchased immediately. It is considered suitable only for the warm season, but can also be used indoors.

There are no restrictions on the dry closet, and it can be placed in any part of the site. A prudent owner will not put it near a source of drinking water, but for those who have a land plot of less than six acres, this is the best option for solving the problem with distances in the territory and lack of space.

Advantages of powder closet

A powder closet looks like a great solution, and many owners use it. However, for the rapid processing of feces, special substances like Biocompostin are required, and they are also not cheap. If excrement is processed without the use of biologically active substances, instead of one year, it will take as many as three, and during this time new heaps of waste will have time to accumulate.

The nuances of the backlash closet

Backlash closet - completely eliminates the ingress of feces into the soil and is considered safe from the point of view of sanitation. However, no one is immune from poor-quality construction or marriage in the construction of this type of toilet. Therefore, there are specially developed norms that must be observed, and they concern not only the distance to the well. There are many components to take into account, sometimes this is the subject of much thought:

• at least 5 m to the foundation of the house, to the road, to the gas pipe;
• more than 10 m - to sewer pipes, lakes or rivers;
• 2 m to the fence, 3-4 - to the trees, 1 m - to the bush and the foundation of outbuildings;
• if there is a reservoir nearby, the distance to it cannot be less than 30 m;
• the minimum distance of toilets with a sealed pit according to these standards cannot be less than 20 m from the water source, but in small areas such a requirement is simply not feasible;
• a sewage truck should drive up to the hatch of the septic tank without hindrance.

Regulations

Nuances

For owners of improperly equipped structures, it is provided administrative penalty, which is why it is said that capital toilets should be planned even before the start of development, and ideally, they should be approved along with the entire plan for placing buildings on the site.

Improper installation of a septic tank can lead to consequences that are dangerous to the environment. Therefore, there are certain norms and rules, where, how and at what distance from other objects it can be located.

It is advisable to think about the place where the device will be located even at the stage of building a house, since it is necessary to provide for many parameters of remoteness to objects not only on the site itself, but also beyond it.

The location of the septic system on the site

In addition, the installation site of the septic tank may depend on other indicators. For example, the type of soil and the level of groundwater flow are very important. This may depend on the type of equipment used. And this, in turn, will also affect the place of its installation.

What is a septic tank?

A septic tank is a structure used to clean feces and drains that go outside the house. Basically, the device is built underground, where sewer pipe all waste is collected.

Exist different types septic tanks. The simplest of them is a storage tank where sewer masses accumulate. There they settle: heavy wastes settle, and light ones float. This feature must be taken into account when pumping out effluents, if it is done independently.

With more complex design, depending on the type of soil, a septic tank with soil post-treatment may be provided. In this case, after the first chamber, similar to the one described above, the clarified water that appeared between the heavy and light wastes in the middle passes into the second chamber. There it is cleaned with the help of special bacteria that decompose the runoff masses. After that, cleaned by about sixty percent, it goes to a specially designated place in the ground.

installation of a septic system relative to the well

The most efficient and modern show themselves local treatment plants. They represent the most complex, but at the same time, an effective purification mechanism, receiving as a result of purification water up to ninety-eight percent purified from sewage. The water is not potable. But, nevertheless, it can be used for technical needs.

The distance from the septic tank to the well is very important, since an incorrect location can lead to sewer masses entering the drinking water. Such pollution can cause people to become infected with dangerous diseases. Therefore, such a norm must be taken seriously and all requirements for sanitary norms and rules must be met.

Of course, when a factory-made septic tank is used, the ingress of effluent masses into the well is negligible, since the design provides for a sealed housing and protection against waste entering the ground. However, emergencies cannot be ruled out, which can be caused, for example, by depressurization of seams, a burst pipe or the “hard work” of stubborn rodents. In case of installation homemade design, the risk of waste getting into the ground increases significantly. Danger can also arise at the stage of installing the device, regardless of whether it is homemade or factory.

That is why it is so important to observe the minimum distance to the well, which, according to existing standards, is twenty meters.

location of the septic tank 20 meters from the well

However, this distance is minimal. If the site is located on soil with excellent filtering capacity (we are talking about sand or sandy loam), it increases to fifty to eighty meters.

To determine the presence of filtering places, special hydrological studies are carried out, which evaluate the composition and quality of the soil in the area around the house.

Also, when installing a septic tank, the placement of water pipes should be taken into account. From them to the device, the footage is measured at least ten meters. Such a norm was introduced in order to protect water from the penetration of sewage into it in the event of a pipe rupture. The septic tank is located below the well or well.

Statutory rules and regulations

For the installation of a septic tank, there are special norms that are mandatory for execution.

To determine the required distance, use the Sanitary Norms and Rules 2.04.02-84 and 2.04.01-85.

They contain information about water supply and outdoor devices, as well as rules for the location of water supply and sewerage.

location of the septic tank according to sanitary standards

According to the documents it is necessary to observe the distances:

• in the case of using filtration fields with an equipment capacity of not more than fifteen thousand liters daily, the distance should be 15 meters;
• when using filters and trenches made of sand and gravel, depending on the capacity of the treatment system, it is allowed, when using a container up to a thousand liters per day - 8 meters, up to two thousand liters per day - 10 meters, up to four thousand liters per day - 15 meters, up to eight thousand liters per day - 20 meters and up to fifteen thousand liters daily - 25 meters;
• filter wells should be at a distance of 8 meters;
• for biological filtration fifty cubic meters per day - 110 meters;
• for facilities for biological treatment, which provides for the possible drying of sediments from the bottom of the silt at an approximate daily capacity of two hundred liters per day - 150 meters;
• for aeration plants with the function of oxidation and processing of seven hundred liters daily - 50 meters.

The location of the septic tank on the site

In addition to the rules providing for a certain distance to water sources, one should adhere to a certain distance from other objects.

From various buildings the septic tank should be located at a distance of seven to fifteen meters. The norm was introduced in order to emergency there was no erosion of the foundation. In the presence of a humid environment, this process occurs very quickly.

Modern hermetic septic tanks can be installed in almost any soil. But it is better to use them in soft and dry soil. In this case, it will also be easier to dig a pit and a trench.

Ideally, the septic tank from the house, at what distance should be located, is from five to seven meters. If the tank is located further than the proposed one, then this will create a risk of blockage. However, such a distance can still be realized, but only if an intermediate well is installed.

We must not forget about the need to pump out sewage, which will have to be done from time to time. Otherwise, the septic tank will simply lose its functionality. Therefore, it is necessary to provide a convenient access to it in order to make it easier to carry out work.

The pipeline from the house to the tank must be straight, otherwise intermediate rotary wells are installed at the turns. However, such a sewerage system automatically becomes less reliable, and its installation will become more difficult.

It is necessary to maintain a distance of four meters from the roots of trees, especially from those with a large root system. But in these places flower beds can be easily planted.

From any body of water - a stream or lake, the allowable distance is from ten to thirty meters.

In addition to complying with these conditions, the location of the septic tank must be agreed with the neighbors. It should be at a sufficient distance from their fence and well.

The distance from the fence in general should be at least two meters, and to the public road - at least five.

You need to know that all these norms are mandatory, because otherwise the owners of the site will have to deal with SES, which have the right to demand even the dismantling of the installation. And this will lead to large material costs. Therefore, it is best to follow all the above rules from the very beginning.

Some nuances

According to the norms, the distance between the sewer system and the filtration well is eight meters. This distance excludes erosion of the earth between structures.

At the same time, the required footage between the filtration well and the well or drinking well is taken into account, which should be thirty meters to obtain liquid using aquifers that have only a continuous water-resistant surface; or fifty meters in the case of other aquifers.

In addition, the exit from the septic tank to the well must be organized according to a certain calculated level. Outlet pipe between septic tank and seepage well must pass at a slope of 2 cm per 1 meter of pipe. Compliance with such calculations will serve as a guarantee of the good functioning of the system as a whole.

the principle of distribution of wastewater in the ground

If organized drainage well, then the distance between objects should be the following:

• between the treatment plant and the drainage - from ten to fifteen meters;
• to trees, fences and residential buildings from three meters;
• before various sources water - twenty-five meters;
• between trenches - from one and a half meters;
• to the groundwater level from a meter to one and a half.

If the drainage well is located too close to the septic tank, this may cause the creation of an overly humid environment, which will lead to the washing of the earth. And if the device was made independently, then it can simply rot.

Excessive moisture will have a bad effect on both trees and buildings. But compliance with all the rules will serve as protection against the penetration of sewer masses into the water supply system.

Sometimes the owners of the house have a question, why is the distance from the house to the septic tank, according to the norms, from five to seven meters?

The fact is that if the distance is large, then the pipeline will have to be laid further and deeper, taking into account the required slope rate. This, in turn, increases the likelihood of blockage, which will be difficult to identify.

If the septic tank is built the other way around, closer to home, then this can cause penetration unpleasant odors inside the home and cause backflow of sewage into the house.

If you buy a local treatment plant that is gaining popularity, then it will reliably protect against unpleasant odors. The placement of such an installation is possible even closer than five meters from the house.
