Standards for the distance of a cesspool from a residential building. Distance from the cesspool to the nearest objects

Sewerage or drainage system in a private house is developed at the stage of its design and planning. This is one of the most important communications. Its installation is quite strictly regulated by the norms and rules of arrangement, protective measures for cleaning and protecting the environment. One of the simplest and most affordable sewerage options for a private house is a drain or cesspool. Despite the primitive design, its device has a lot of nuances that must be taken into account.

Sanitary norms and rules (SanPiN and SNiP) for this type of buildings were not developed by chance. They have been operating on the territory of Russia since the days of the Soviet Union. Even then, it was noticed that the absence of any rules for the arrangement of a drain pit, with a certain density of residential buildings, and a small distance between them, it can cause serious damage not only to the environment, but also to people living in this area. After a series of studies in this area, a feature of wastewater was noticed to seep into the ground, reaching the upper threshold of groundwater. The result was uncontrolled pollution for many years, the effects of which were felt on soil fertility and the quality of the region's water resources.

Certain difficulties are caused by the secrecy of the building, the very presence of which and the quality of the construction work performed on its arrangement is often extremely difficult to determine. However, the harm is primarily felt by the owner, who violates the standards and rules for making a drain pit, as well as neighbors living in neighboring areas. Therefore, when designing a section of a private house, the construction of a drain pit must be carefully studied, thought over and not too lazy to coordinate sanitary standards with the local SES in order to avoid mistakes and violations that could lead to irreversible consequences for the site's ecology.

Compliance with the rules for placing and protecting the internal space of the cesspool, on the contrary, is quite legal and permissible, especially since in some cases this is the only rational way to construct a sewerage system on the site of a private house.

What are drain pits

Structurally, drain pits can be divided into several main categories:

With soil post-treatment;
Sealed (with storage).

To begin with, it is worth noting what is a violation in such a device of technical rules and regulations. And first of all, this is the absence of any protection at the bottom and walls of the cesspool. Drains, falling into its area, freely and unhindered penetrate the soil, getting stuck there for many years, disrupting the ecological balance. Some of them are digested by aerobic bacteria. But putrefactive processes continue in the soil, and make it less suitable for agriculture. With a great remoteness of vegetable gardens and neighboring similar buildings, the damage from them is less significant and tangible. In the absence of insulation materials, this method was generally the only one possible for many years. But times have changed. Today, you can easily get any material and equip a modern cesspool without harm to the environment and to yourself.

So, an autonomous sewer in the form of a drain pit can be equipped as follows:

Monolithic reinforced concrete structure- one of the most durable materials that do not collapse for a long time is reinforced concrete. Even with a small wall thickness of such a container, the reinforcing cage will perfectly contain any tensile loads. To form the pit container itself, OSB or plywood formwork set at a certain distance (15–20 cm) is used. The bottom can also be made monolithic or filled with sand and gravel mixture by 30 - 40 cm, as an additional filter. In the first case, any ingress of sewage into the soil is excluded, however, sewage works will be quite frequent. In the second case, for some time the filter will cope with its purpose, but after silting it will need to be replaced. The volume of effluents, subject to their filtration and sufficient dimensions of the pit, is no more than 1 m 3 per day;

Important!
The drain pit is often accompanied by a fetid odor, especially in the hot season. Aerobic bacteria will help to cope with this disadvantage, which not only eliminate unpleasant odors, but also help to process dense biomass into a more liquid one and suitable for further filtration.

Brick or cinder block cesspool- an option in which the walls and bottom of the pit are laid out from piece materials, such as brick and cinder blocks. The method is not bad, but you need to take into account the dressing of all seams with an iron bar or reinforcement. After the finished surfaces are plastered with a cement-sand mortar, followed by its ironing. In addition, it can be covered with bituminous mastic to increase waterproofing. The bottom can also be made airtight or with soil aftertreatment;

Important!
The depth of the cesspool should not be made more than 3-4 meters, since the length of the sewer hose may not be enough to empty the entire well. This will lead to the fact that silting will be permanent at the bottom and filtration in it will simply not be possible.

Drainage pit from reinforced concrete rings and blocks- ready-made reinforced concrete structures, standardized in production, greatly facilitate the construction of such buildings. The only negative is their weight, which slightly complicates the installation work and their transportation to the site. On the other hand, this is a great way to speed up the construction process by eliminating the “wet” work of pouring concrete and plastering. Connect the rings or blocks to each other by welding, and thoroughly lubricate the seams with waterproofing mixtures, mortar;

Important!
If this is a free-standing well, it is covered with an airtight lid to prevent precipitation from entering it. During the decomposition and fermentation of sewage, explosive methane is formed. In this case, the cover is equipped with an outlet - a small piece of the ventilation pipe that goes out.

Finished container or drive- this method is the most modern, since a container made under production conditions acts as a pit. It can be a tank, a barrel made of metal, concrete or plastic. The latter is especially in demand due to its low weight and resistance to corrosion. Depending on the depth, the walls of such a container are insulated and strengthened. In addition, sewer pipes of any diameter are easily connected to them, which can be cut into their walls. Sealed capacity allows you to reduce the distance from residential and other objects of the site.

Rules and norms of SNiP and SanPiN for the arrangement of cesspools in household and summer cottages

Having decided on the type of cesspool, it is necessary to calculate its location on the site. For this, there are restrictive recommendations of the following documents:

SanPiN 42-128-4690-88 "Sanitary rules for the maintenance of territories of populated areas";
Code of Rules SP 32.13330.2012 “SNiP 2.04.03-85. Sewerage. External networks and facilities”;
SNiP 30-02-97: "Planning and development of territories of horticultural associations of citizens, buildings and structures."

The remoteness of the drain pit, especially with soil additional filtration, according to the SNiP standards, should be at a distance of:

From a residential building - 8 - 10 m;
Outbuildings - 5 - 7 m;
Fence - at least 1 m;
Neighboring house - 10 - 12 m;
Water intake wells - 20 - 30 m;
Water pipes - 20 - 25 m;
Gas pipes - 5 m;
Trees - 5 - 7 m.

Advice!
The type of soil and its properties also matter when laying sewers. Clay soils are dense and oily, they conduct water worse. Cesspools in such soils should be at least 20 m from natural wells. For loams, this parameter is already 30 m, for sandy soils - 50 m.

In design work, the sewerage of a private house must be taken into account in full, since it consists of an internal (located within the house) and an external part (the rest of the sewerage on the site). A detailed drawing will help calculate the amount of materials for the sewer, its location on the site, determine whether it will be gravity flow or whether it needs to be forced, and at what distance from residential and utility buildings on a suburban area.

For professional plumbers, engineers, designers, the solution of these problems is not difficult. But for the average layman, these rules of SniP and SanPiN are not so complicated, because a cesspool is the most primitive, and at the same time, the cheapest sewerage device in a summer cottage that you can do yourself.

Usually, in private households, the problem of sewage and sewage disposal is solved by building cesspools on household plots. There are certain standards that clearly prescribe how the process of arranging septic tanks and other treatment facilities serving individual residential buildings should be carried out. They are not recommended to be broken.

When a cesspool is created, sanitary standards are regulated by the Law of the Russian Federation N52-FZ of 1999 “On the sanitary and epidemiological well-being of the population”. The requirements specified in it are mandatory for citizens of the country.

Sanitary standards for cesspools

According to the text of the regulatory document, cesspools (see photo) must be built with a mandatory special filtration device, and they should not have a normal bottom under any circumstances, especially if the amount of drains exceeds one cubic meter during the day.

At the same time, it should be noted that during the construction of a cesspool for servicing a heated house in which at least 4 people will live, the sump should be made with a special bottom.

There is no single answer, what should be the distance from the house to the cesspool. The requirements for this parameter are ambiguous. The minimum distance between these two objects is 15 meters (read also: "").

Such a distance is required from the house to the drain pit so that the toxic gases emitted by the waste do not harm the environment on the ground and the people living in this area.

If it becomes necessary to make the distance from the pit to the water supply closer, then you should contact the appropriate authorities (Sanidemic Supervision) and utility service companies (for example, the water utility department, etc.).

Rules for arranging cesspools

If a cesspool is being built, sanitary standards must be observed. Sedimentation tanks with a working volume of not more than one cubic meter of sewage and sewage per day belong to the classic version of cesspools for servicing summer houses and country houses, in which people live in intermittent conditions and water heating equipment and household appliances are not used.

According to sanitary requirements, the distance from the septic tank to the summer kitchen cannot be less than 5 meters. In the event that the daily volume of wastewater reaches 8 cubic meters, the distance should be increased to 8 meters.

The rules for arranging cesspools provide for compliance with a number of requirements:

when the drain per day is 3 cubic meters - the pipes must be located as close as possible to groundwater (distance 40-50 meters);
pipes should be mounted upwards relative to the flow of groundwater;
if there is an artesian source in the immediate vicinity of the house, the distance from the well to the cesspool should be at least 20 meters.

In the case when homeowners do not have the opportunity to keep the distance of the drain pit from the house and sources of drinking water, experts recommend making wells or cappings for several houses at the same time. In this case, it is necessary to observe 2.5-5 meters of indentation from the "red line". Before starting work, it is imperative to know how to make a drain pit correctly and according to the norms.

SanPiN 42-128-4690-88: requirements and standards, installation distance

On the territory of the Russian Federation, regardless of the region of residence, SanPiN requirements for cesspools apply.

When a private house does not have a centralized sewer system, its owners are allowed to locate a cesspool on the site. The main requirement for it is mandatory water resistance. Above the sump there should be a lid to close it and a special grate. You can equip a common drain pit with neighbors.

When a private house is located near a school or kindergarten, then the distance should be at least 20 meters. If you have any questions regarding the arrangement of a cesspool, the owner of suburban real estate should contact the local administrative authorities.

But there is a general rule for all private households - the sump should be located so that the distance from the well to the cesspool is 50 meters.

Treatment facilities must be cleaned at least once every six months.

When disinfecting drain pits, a product is used, the components of which are:

5% sodium hypochlorite;
5% - creolin;
10% lime chloride;
10% - naphthalizol;
10% - sodium metasilicate.

Under no circumstances should dry bleach be used for disinfection.

Additional requirements for the arrangement

In addition to the requirement, what should be the distance between the well and the cesspool, there is another important point - this is the tightness of the treatment plant so that sewage does not poison the soil and aquifers, since in this case the environment will be harmed.
The building materials used in the arrangement of sedimentation tanks (bricks, boards, blocks) must differ in density
Drains should not be allowed to be above the mark of 35 centimeters from the ground surface, since then the owner of the property himself is unlikely to be able to cope with the negative consequences.

There are also requirements for the distance from cesspools to utilities:

from the water supply from asbestos-cement pipes to septic tanks and drain pits, the distance should not be less than 5 meters;
when using cast-iron pipes with a diameter of not more than 200 millimeters - 1.5 meters;
in the presence of pipes made of cast iron with a diameter of more than 200 millimeters - 3 meters;
to gas pipes - more than 5 meters.

To prevent the unpleasant smell from disturbing the residents, it is necessary to observe a 5-meter distance from the building to the cesspool. The sump should not be located closer than 1.5 meters to the boundary of the site.

A cesspool is an important part of the sewerage system, which is why its construction should be carried out not only in agreement with specialists, but also with state normative documents. "SanPiN: Cesspools" includes several categories of requirements, each of which must be observed without fail.

Ignoring the instructions on this matter promises you not only penalties, but also a lot of problems. For example, the wrong location of the cesspool can result in an unpleasant smell in the house and even fraught with diseases that can be obtained after sewage enters drinking water.

The main document that you should be guided by when building a cesspool is SanPiN 42-128-4690-88 “Sanitary rules for maintaining the territories of populated areas”. It is here that the primary requirements to the location, design and maintenance of the cesspool.

It was developed and adopted back in the Soviet Union. Analogues of the document were subsequently adopted in almost all CIS countries. Despite its relatively long history of existence, the sanitary standards set out in this document still remain relevant, however, not all of them.

For example, many modern experts in the field of sewage arrangement recommends slightly increasing the distance from the waste collection tank to the dwelling or additional buildings. Let's talk about this in more detail in separate sections.

Requirements for the location of the waste collection pit

The very first thing everyone who decides to install a cesspool on the site should know is shortest distance to a residential building.

According to the previously mentioned document, it should be from 15 m and more. If it is impossible to install a container at such a distance, it is possible to bring it closer to the building only after agreement with some services.

However, experts do not recommend deviating from this requirement. In the process of decay of waste, which invariably occurs in the pit, various gases are released. Also, do not forget about the natural unpleasant smell. In summer, especially with open windows, all these aromas will penetrate into the house. As you can imagine, this is not pleasant.

It is necessary to take into account the distance from the cesspool to the nearest water pipes. Compliance with this paragraph "SanPiN cesspools" is one of the most difficult, because you also need to take into account direction of movement of groundwater.

If they flow from the drain pipe towards the cesspool, then the minimum distance is 25 m. If in the opposite direction, then the distance increases to 40 m.

At about the same distance, the cesspool should be located from the nearest source of drinking water, a well or a well.

It is also necessary to take into account the distance to the fence, at least 2 meters. In this matter, experienced installers also give their recommendations. It is best to install the pit near the entrance to the yard, so it will be much easier to clean.

Pit design requirements

Cesspools used for autonomous sewage must be closed with a grate and a hatch. In cases where the design is used for a country toilet, it must be equipped with a solid threshold that will leave only a small part of the waste collection container open.

The maximum depth of the cesspool is 3 m, but only if the groundwater passes below this level.

On the site with high groundwater level, it is best not to use a cesspool at all. Even if you choose a closed design, some of the waste can still get into the water layer. This is especially dangerous in cases where drinking water in the area is supplied by purifying liquid from nearby reservoirs, wells or wells.

Requirements are also put forward for the selection of the volume of the cesspool.

So, for example, a small structure, up to 2–3 cubic meters in volume, can only be installed for a country toilet, or in an autonomous sewerage of a house where no more than two people live.

In all other cases, the required volume of the pit is selected according to a certain formula, which takes into account both the water consumption and the number of days during which the pit will not be cleaned.

Basic care requirements

For cleaning and preventing unpleasant odors in the cesspool forbidden use chlorine and bleach. These chemicals completely kill all microflora and microfauna inside the structure, and it plays a very important role in the processing of organic waste.

It is best to use for these purposes biological preparations, which not only do not interfere with natural biological processes, but even accelerate them.

Cesspool cleaning

When designing a country or country house, it is necessary to immediately take into account the arrangement of the drainage system. The best solution to this issue today would be a cesspool. To implement your plans, you need to study specific recommendations, tips and established regulations on the topic of a cesspool - sanitary standards.

The design and arrangement of an autonomous sewage system for a private household is associated with compliance with sanitary requirements, certain norms and rules that are mandatory. In case of violation of the points of sanitary standards during the design and construction of a cesspool, its operation can then bring many problems and considerable fines.

Failure to comply with the requirements of even a part of the established rules leads to pollution of natural sources of drinking water and the spread of infections. Therefore, the ideal option before building a cesspool would be to include it in the development plan and coordinate with all government services involved in this issue, including SES. This is necessary to obtain building permits.

How to choose the right construction site?

The cesspool is a container for the accumulation of domestic wastewater. To determine its location and harmonize with the regulations of sanitary standards, it is necessary to analyze your site and the surrounding area.

To do this, you need to study the schematic plan of the site, where the location is indicated:

residential building;
outbuildings;
wells;
gas pipelines;
water pipelines.

Here it is necessary to take into account the elements of the landscape, lowlands and highlands. When planning, the location of neighboring houses, wells and communication systems in nearby areas should be noted in order to allocate areas for a “sanitary zone”. When planning the location of the cesspool, it is necessary to take into account the direction of movement of groundwater. Information about them can be obtained from the relevant services.

Conditions and standards for choosing the location of the pit

After analyzing the schematic plan, it is necessary to choose the optimal place for the cesspool. According to sanitary requirements, it must be removed:

From the neighboring house and its facilities - 10-12 meters.
The boundaries of the site - not less than 1.5 meters.
Residential building - at a distance of 8 to 10 meters.
Water intake wells - 20 meters.
Water pipes - 25 meters.
Underground groundwater flows - at 25 meters.
Gas pipes - 5 meters.

When building a cesspool, the condition of the soil at the location of the device must be taken into account. On clay soils, according to sanitary requirements, natural wells should be located at a distance of 20 meters from the pit. On loamy soils, they move away by 30, and on sandy or supersandy soils by 50 meters.

What type of cesspool to choose

Important Ingredients

The simplest option provided by SNiP is a bottomless cesspool. It is designed for small waste emissions up to 1 cubic meter per day. During this time, the effluents have time to pass naturally into the soil, and the aerobic soil bacteria process them.

Accumulated sludge from such cesspools should be removed periodically - once every six months. However, this is the easiest and most affordable option for receiving and disposing of wastewater. It belongs to the type of village toilets, which are no longer relevant today due to their low resource for receiving wastewater and unpleasant odors around it. In addition, such structures today can be environmentally hazardous.

If more than two people live in the house, accustomed to the comfortable conditions of urban life, it is necessary to consider options for arranging sealed cesspools. They are environmentally friendly, and waste from them will not fall into the soil. One option that meets the requirements of SNiP is a pit made of concrete, cinder block or brick. An excellent solution to the issue of discharging domestic wastewater would be a sealed storage septic tank made of plastic.

Pit requirements

The depth of the sealed pit must be made no more than 3 meters. This is due to its maintenance by a sewage truck, the hose of which is designed for a 3-meter length of sewage intake. If you make the hole deeper, the cleaning efficiency will decrease due to the constantly remaining sediment at the bottom.

The sewer pipe entering the pit should be 10 cm in diameter. The depth of its laying in the ground is 1.2 m, which ensures its safety in winter. The slope of the pipe towards the drain pit must be at least 3%.

sewer manhole

The entrance of the sewer pipe into the wall of any constructive solution of the pit must be made soft. For these works, bitumen and ordinary building foam are excellent.

The bottom of the pit is equipped with a mandatory slope towards the hatch, which will ensure better pumping of sewage. To exclude the possibility of an explosion in the pit, it is necessary to install a ventilation pipe with a diameter of 10 cm and bring it above the ground to a height of at least 60 cm.

The decomposition of organics in the pit results in the formation of methane gas, which often causes an explosion. Therefore, it must be removed from the internal volume of the sealed pit.

For the operation of the sewage truck and maintenance of the pit, it is necessary to provide an accessible entrance to it. It will be necessary to call the car 2 times a month at a consumption of more than 150 liters of water per day per person.

Types and design of autonomous sewer systems

Sewers for autonomous use are divided into:

For non-volatile. In this case, the drains flow into the pit naturally.
Volatile - at the same time, a pump is required to pump out effluents.

The main condition for arranging an autonomous wastewater storage tank is the complete tightness of the structure. Installation of ready-made septic tanks on the site provides absolute sealing, which is guaranteed by the manufacturer.

A cesspool can be designed and constructed from a variety of materials, including brick, cinder blocks, or prefabricated concrete blocks and rings.

Features of brick and cinder block pits

Scheme of the sewer system

The construction of a brick or cinder block pit takes a lot of time and labor, but it ensures full compliance with the requirements of SNiP.

The main stages of construction work:

The walls of the pit are laid out with bricks or cinder blocks with mandatory dressing of the seams.
The inner surface is plastered and ironed.
The outer perimeter of the masonry is smeared with a 20-cm layer of greasy clay.
The bottom of the pit is also first smeared with a layer of the same greasy clay, and then concreted from above, followed by ironing the base of the cesspool.

Construction of a cesspool from blocks and rings

The use of reinforced concrete rings and ready-made concrete blocks for the construction of a cesspool has several advantages, but requires special handling equipment for their installation. For the construction of a cesspool, it is necessary to have a cover, a bottom and at least 3 rings.

After excavation and cleaning the base of the pit, the bottom must be concreted. Then you need to finally check all the dimensions according to the project in order to carry out a successful installation of the rings. After installing the rings, their inner surface is covered with bitumen, having previously sealed the joints with concrete. Similar work is carried out at the bottom of the pit.

When constructing a cesspool made of reinforced concrete or concrete products, special attention is paid to waterproofing so that during operation the pit is not filled with melt or rainwater.

After connecting the sewer pipes, a hatch is mounted and the structure is covered with earth.

Conclusion

Biological product for cleaning cesspools

Recently, ready-made projects for autonomous cleaning systems have been developed. All of them are volatile and expensive, but at the output the customer receives a complete and complete "turnkey" system of modern biological treatment.

Air and reagents are injected into these systems, and harmful wastewater substances after biological treatment become harmless. Today it is the most effective method of wastewater treatment, providing for water purification up to 98%. Special permission from the sanitary services for such systems is not required.

For country houses and dachas, it is very important to provide the benefits of civilization. This issue is especially relevant for structures located far from centralized engineering networks. In most cases, to solve such problems, a well is built on the territory of a country house or cottage, a well is drilled and a cesspool or septic tank is equipped. These engineering structures will solve the problem of providing water to a residential building, as well as wastewater disposal. However, when placing a hydraulic structure and a cesspool on the site, it is very important to observe the standard distances. Compliance with sanitary standards will help maintain the quality of drinking water from the source at an appropriate level.

Sometimes even the construction of a water intake structure in compliance with the technology and rules will not insure you against contamination of the source. The thing is that potential contaminants can appear already during the operation of the well. One of these pollutants can be a cesspool. At the same time, such a structure can be built not by you, but by your neighbors who do not adhere to the standards for sanitary protection gaps.

In this case, the minimum distance from the well should be observed to the following sources:

drain sewerage;
sewage treatment plant for wastewater, the volume of which does not exceed 25 m³ per day - a septic tank;
cesspool.

The distance between the well and the sewage pit is essential, since this structure can cause dangerous pollution of the environment and sources of drinking water due to a significant accumulation of sewage.

Despite the fact that modern materials guarantee a high degree of tightness and durability of the cesspool, you cannot be completely sure of safety, because the risk of leakage is not excluded. That is why a standard distance must be observed between such a pit and a well or well. This is the only way to be completely sure of the safety of drinking water.

Usually, all sanitary protection zones are specified in the regulatory documents SNiPs and SanPiNs. Moreover, the gap between the source of drinking water and the cesspool depends on the performance of the latter structure. Usually this distance is at least 50 m. In this case, the gap between them can be increased depending on the volume of filtration of the cesspool:

if the water consumption per day is 1-2 m³, then the zone is 8-10 m;
at a flow rate of 4-8 m³, the zone increases to 15-20 m;
if the flow rate is 15 m³ or more, then the gap increases to 25 m or more.

Attention: in the sanitary protection zone there should be no open sources of drinking water (wells, reservoirs) and closed sources - wells.

Well placement requirements

The distance from the well to the waste pit depends on various factors. When determining this gap, it is worth considering such indicators as:

hydraulic connection between the rock and the aquifer, because it is the soil that performs the filtration functions for water entering the water layer;
the composition and quality of the soil, since sewage can seep through it into the source (water seeps through the sandy rock most easily);
the depth of the passage of groundwater (a cesspool structure without a bottom cannot be buried below the aquifer);
direction of fluid flow in the underground aquifer (for wells located downstream of the sewage pit, there is a high risk of contamination).

Depending on the indicators of the rock, the gap between these structures can be as follows:

impermeable rock (impermeable clay is considered the most impermeable, in this case the gap from the pit to the source can be reduced to 30 m);
permeable rock (sand) - in this case it is better to make a maximum gap of 50 m.

Choosing a place for a hole

As a rule, a cesspool is built on the territory of a private house. When placing this object, it is important to observe not only the distance to the well, but also to other buildings on the site:

from water supply networks it is necessary to retreat at least 100 cm;
to mine wells, it is worth observing a gap of 20 m;
from the well to the pit, it is worth making a gap of at least 30-50 m;
between houses and other buildings and the pit, it is worth making a gap of at least 10-12 m (it is important to take into account the structures in neighboring areas), otherwise the waters can wash away the foundation, violate the integrity of the building and cause it to flood;
from the fences it is worth retreating at least 1 m;
the free access of special vehicles should be provided to the pit.

Attention: it is forbidden to make sewage pits with a depth of more than 3 m. The thing is that deeper structures, even for a sewage machine, will be very difficult to clean. Pumping equipment will not be able to lift all sewage from the bottom of the structure.

When choosing a place for a cesspool, it is important to consider the relative placement of water and gas pipes. In this case, you should adhere to the following requirements:

The sewer pit must be located at a distance of at least 500 cm from pipelines made of asbestos cement or reinforced concrete.
When laying a pipeline of cast iron pipes with a diameter of not more than 20 cm, the distance should be 1.5 m or more.
If cast-iron pipes of a significant diameter (more than 20 cm) are used, then the gap increases to 3 m.
The sewer pit should be located no closer than 5 m from the gas pipeline.

Wells and small cesspools

When building a small cesspool with a capacity of 1-8 m³ per day, the requirements for normalized sanitary-protective gaps are somewhat softened. So, from the house of such a structure, you can retreat at least 5-8 m.

A small sewage pit can be located at such a distance from the water intake and its structures:

If the waste structure has a filtration volume of no more than 3 m³ per day, then the laying of a pipeline that supplies drinking and household water from the water intake to the house can be done downstream of the liquid in the underground water horizon. In this case, the distance between the structures should be at least 40-50 m.
If, with the same volumes of the cesspool, the source is located upstream in the aquifer, then a gap of 25 m can be observed between them.
When placing a septic tank perpendicular to the movement of liquid in the water horizon, the distance between the source and the cesspool is 25-30 m.
From artesian sources and wells, sewage pits and other sources of potential pollution should be placed at a distance not exceeding 20 m.

It is important to know: the optimal placement of a sealed septic tank is downstream of the water in the aquifer, and the water intake facility is upstream.

As you can see, the construction of cesspools and sources of drinking water must comply with many different requirements. Often, it is simply impossible to observe them all at one site, especially considering the buildings in neighboring areas. In this case, professional craftsmen use one universal solution:

first, water intake structures (wells, wells, columns, etc.) are organized in several neighboring areas;
then a concrete or asphalt platform is made (in this case, the slope of the surface should be 5% of the walls of the structure);
the dimensions of this area must be at least 3x2.5 m;
the distance from the red lines of the street should be at least 250-500 cm.
