Who rules the ball in the underworld: factors affecting the distance between sewer wells

Surely you at least once in your life wondered why so many sewer manholes come across on your way. Looking ahead, I will say that this is not someone's whim, but a necessity dictated by technical requirements when laying the sewer system. To clarify these points, I have summarized all the current regulations and will gladly share my knowledge with you. So, let's hit the road.

Everyday educational program

For those who do not like to read for a long time, I inform you that, according to clause 4.14. SNiP 2.04.03-85 on all sewer networks, without exception, wells are provided. The permissible distance between two underground devices depends on the diameter and ranges from 35 to 300 meters.

Those who really want to find out the features of the location of sewer wells should arm themselves with a couple of minutes of patience and read the article to the end.

So, what is hidden under the hatch? Directly below it is a special hydraulic room, called ... yes, yes, a well. Depending on the type, they are designed for a specific type of maintenance work:

1. manhole serves for direct control of complex sections of the sewage system. In the event of clogging, which is inevitable when sewage is removed, both social and industrial, through such wells, repair teams gain access to problem areas;

1. Rotary wells duplicate the functions of observation points, located at points of direct change in the direction of movement of sewage. Turning or bending the sewer pipe increases the likelihood of blockage; this type of underground structures allows to quickly eliminate the problem;
2. Where the landscape creates too much slope, or at the intersection with other engineering and technical underground structures, drop wells are installed;

It would seem that the greater the slope, the faster the drains will leave the pipe. But in fact, an excessive slope, like its complete absence, harms the sewer system - the solid fractions of wastewater, not keeping up with the more liquid ones, accumulate, clogging the pipe lumen.

In the photo - a sewer differential well with the cover removed.

1. Nodal wells unite several pipelines and allow them to be controlled.

Regulatory documentation

Let you not be surprised by the fact that SNiP 2.04.03-85 of the USSR Civil Code for construction, approved back in 1986, still regulates the construction of sewer networks.

In our time, and more specifically, in 2012, the Ministry of Regional Development published the Code of Rules SP 32.13330.2012. In fact, this is a revised edition of SNiP 2.04.03-85, which introduces some additions to the text.

Along with this, there is also SNiP 3.05.04-85, which pays more attention to the laying technology and the materials used.

Well dimensions

cross section

We return to the wells. The cross section of reinforced concrete rings, from which in most cases they are constructed, depends on two factors:

1. Sections of the sewer pipe over which it is erected;
2. Depth.

For the first parameter:

If the depth of the well exceeds 3.0 m, then the smallest diameter of the rings must be at least 1.5 m.

The typical height of the well (its working part, measured from the tray to the cover) is 1.8 m. It is quite expected that this value is affected by the terrain - either upward or downward. For example, if the depth is >1.2 m, then the cross section should not be less than 1 m.

Depth

Regarding the depth of occurrence, it should only be said that this value depends not only on climatic conditions.

Soil loads should also be taken into account, for example, when a pipe is located under a roadway. The price of an error is very high - from the likelihood of freezing pipes in winter periods before damage or depressurization of the sewerage by vehicles passing over it.

In some cases, sewer pipes can be laid in reinforced concrete tray, as well as additional insulation.

Distances according to SNiP

Lookouts

Let's move on to the most interesting - knowing which type of wells we are talking about, we will find out the largest and smallest distances between sewer wells according to SNiP. Let's start with the manholes.

In practice, the distance is determined based on the cross section of the sewer pipe connecting two wells:

Diameter (Ø) of the pipe, m	Min. allowable distance, m
0,15	35
0,20 – 0,45	50
0,50 – 0,60	75
0,70 – 0,90	100
1,00 – 1,40	150
1,50 – 2,00	200
Over 2.00	250 — 300

Rotary and nodal

There are no specific values ​​regarding distances in the regulatory documentation for this type of wells. Why?

To answer the question, you should remember for what purposes they are built:

1. Nodal - in all places of connection sewer pipes;
2. Rotary - in all places where the pipe changes direction. Moreover, they must be taken into account by the project at each point of change in the slope of the landscape or the section of the pipe.

The pipe turning radius also plays a role:

1. If the pipe Ø exceeds 1.2 m, then the minimum turning radius is 5 Ø.
2. If the pipe is less than 1.2 m, then the turning radius is equal to its Ø.

Captain Evidence suggests: for pipes of large Ø at the beginning and at the end of the turn, manholes are built without fail.

Now you know that there are no specific figures indicating the distance between the nodal and rotary wells in SNiP - everything is determined individually when designing the sewer network of a particular object (house, quarter, district).

Variable

About drop wells should be told in more detail. Such structures are installed in places where there is a large difference in height between the incoming and outgoing pipes.

The very slope of the pipes of the external sewer network primarily depends on:

• landscape;
• Underground structures and structures encountered on the path of sewage flow;
• Depth of inlet pipe.

At the same time, the design of overflow wells will also be different. For example, to reduce the flow rate, the design of the well will be multi-stage. There are often designs where, instead of pipes, a simple channel is used, which has the required slope.

Pipes

Pipe Ø also affects the distance between wells. Let's find out this nuance.

When laying sewer system The following dimensions of the waste pipes must be taken into account:

• 0.15 m for an intra-quarter network for domestic or industrial purposes;
• 0.20 m for the street sewer network;
• 0.25 m for street storm water.

If in a settlement the volume of wastewater is >300 m3 per day, then the smallest diameter for the intra-quarter and street network is 150 mm.

Sanitary protection zones

One more thing important aspect worth mentioning - these are sanitary protection zones that affect the location of sewer wells. The parameters are determined by the performance and the type of structure used.

It is clear that such information does little for a simple developer in terms of practical application. Therefore, I will explain the parameters that must be followed when designing an autonomous sewerage system for a private household.

For example, let's take its productivity equal to 15 cubic meters per day:

• For the section of underground filtration of wastewater, the sanitary protection zone will be 15 m;
• For a trench filtering drains or a sand and gravel filter - 25 m;
• At least 5 m should be from the foundation to the septic tank and at least 8 m to the filter well.

The diagram indicates 3 meters - this is the minimum distance from the sewer to the foundation of the cottage. But we are talking about a nodal well!

Legal and legal liability

In legislation Russian Federation penalties are provided for violations of the requirements of SNiP for design and installation outdoor sewerage, as well as a measure of responsibility.

The following persons are responsible for compliance with the rules and regulations:

1. design organizations - established responsibility for the correctness of plans, drawings and all preliminary calculations for the design of an external sewer network;
2. customers and developers - the responsibility for the preparation for operation of the installed sewer network has been established. This includes: personnel moments, the correct selection and operation of equipment, commissioning processes, etc.;
3. Research Institute - established responsibility for the issued data on climatic conditions in the region where the installation of the sewer network is carried out;
4. construction and installation organizations - full responsibility is established for compliance with all norms and rules during construction and installation works and testing of the completed structure.

When checking and identifying violations for these categories of persons, a decision is made to bring them to administrative, disciplinary and, in case of serious consequences, even criminal liability.

In the course of investigations of accidents related to the malfunctioning of the sewer network or its breakdown, specific perpetrators are identified and the degree of guilt of each of them is established.

Do not think that the responsibility lies only with those who design and build objects of state and municipal outdoor sewerage systems.
Any citizen who is engaged in independent design and installation of an autonomous sewer network is also responsible for violating the requirements of SNiP and environmental laws.

The negligence or inaction of the responsible person, non-compliance with applicable rules and regulations, which led to an accident or breakdown or interfere with the normal operation of the sewer pipeline, is also classified as a violation with all of the above consequences for a particular culprit.

For the construction of a well on the site, there is not enough space with an accessible level of occurrence of the aquifer. The fact is that there are a number of other requirements for the location of the source of water supply, and if they are not met, then the water will not be difficult to use for food purposes.

Then we will consider these requirements, fulfilling which, you can avoid the troubles associated with poor water quality.

Sanitary requirements

First of all, go to state that the choice of a place for the execution of the well must be made without fail with the participation of a representative of the state sanitary-epidemiological station, or the sanitary inspection. In addition, it is possible to invite a doctor assigned to this area for these purposes.

But, first you have the opportunity to find the most suitable place for yourself.

In accordance with SanPiN 2.1.4.544-96:

• The source should be located in an uncontaminated area located at a distance of at least 50 meters (upstream of the aquifer) from existing or probable pollutants, for example, the distance from the cesspool to the well should be at least 50 m.
• The place should not be swampy or flooded with flood waters. In addition, it is forbidden to install water supply sources in places that are subject to landslides and other types of deformations.
• The source should not be located closer than 30 meters from roads with heavy traffic and highways.
• There is no need to locate the source on the slopes, on the banks of rivers or near ravines, because. untreated river or ground water will inevitably get into it.

Note! If the probable source of pollution is located above the well in terms of the terrain, then the distance between them should be at least 80 meters, and in some cases even 150 meters. This point should be taken into account if neighboring areas are located higher in the relief, since the distance between the well and cesspool should already be not 50, but 100 meters.

What are the specific sources of pollution?

The sources of pollution include a number of objects:

• Cesspools and pits;
• Burial places of animals and people;
• Warehouses for pesticides and fertilizers;
• Industry enterprises;
• Sewer facilities
• Landfills, etc.

From this it follows that when choosing a place, it is necessary to focus on the distance from the well to the toilet, and on the distance from other objects of pollution in your own and neighboring areas. This is due to the fact that unwanted elements will enter the water, as a result, it can be detrimental to health.

Distance between two wells

Minimum distance between water wells according to SNiP, in addition, there must be at least 50 meters, since the well is a potential pollutant. This is due to the fact that pollution can get into it from above or through leaky walls.

The minimum distance between wells, which extract water from different aquifers, can be reduced to 30 meters. But, such cases are rarely seen, in most cases, the sources in neighboring areas are made at the same depth.

Distance to residential buildings

As for the distance from the house, there are no restrictions, but the distance from the well to the foundation should be such that construction equipment can drive up when it is being installed.

In addition, at a time when the distance from the well to the house exceeds 100 meters, the source is not very ergonomic in operation. This is especially true of those cases at a time when water has to be collected manually.

Advice! be guided to keep in mind that during the installation of a structure located close to the building, its foundation may be damaged. Based on this, it is necessary that the distance from the house to the well is, nevertheless, reliable.

Design device requirements

So, you have decided on the choice of place, along with this, the distance between other sources and wells of the pollution water supply has been correctly chosen. But, this is not enough for the source of water supply to be invariably filled with clean water. drinking water.

Based on this, you need to familiarize yourself with the requirements for the design of the well itself, especially if you plan to do it yourself.

They consist of several items:

• The column must have a cap (above-ground part), which protects the shaft from clogging, and helps for it with a fence and allows water intake. The height of the head is not less than 0.7 meters.
• The headroom must be closed with a well cover or a reinforced concrete ceiling with a hatch. From above it should be covered with a canopy or equip a "house".
• Along the perimeter of the head, if the distance from the well to the building allows, it is necessary to make a “castle” of carefully compacted clay 2 meters deep and 1 meter wide. In addition, it is necessary to make a blind area made of concrete or asphalt, with a diameter of 2 meters or more, without fail with a small slope.
• Near the column, head to complete the fence and build a bench for buckets.
• The walls of the shaft should well isolate the structure from the penetration of perched water and surface runoff. it is better to use cement well rings, the drains of which are sealed with mortar, as required by the instructions.
• The water intake part of the mine, intended for the accumulation and inflow of groundwater, must be deepened into the aquifer. For better water flow, lower walls must have holes.
• To prevent bulging of the soil by ascending flows and the appearance of turbidity in the water, a return filter should be poured at the bottom.
• To descend into the mine, when performing repairs and cleaning the source, it is necessary to install cast-iron brackets, located in a checkerboard pattern at a distance of 30 cm from each other.

Here, perhaps, are all the rules that you need to know before executing a water supply source.

Advice! Before using the well at the end of its device, the water must be completely pumped out twice. Before using it for food purposes, you need to perform a chemical and bacteriological analysis in a specialized laboratory. Indeed, keep in mind that the price of these services is high.

Conclusion

All of the above requirements must be met in strict order. This is the only way to ensure that the well is filled with drinking water. Otherwise, all the construction costs will be in vain, or even worse - the water from it will harm your health or the health of your family members.

Regulations are very difficult to master, especially for non-professionals. To understand all the requirements for engineering networks, you need to spend a lot of time processing a large amount of material. It is also quite problematic to find exactly the information you need on the web: often the search results turn out to be completely different from what they should be.

This article will describe all the information that relates to sewer systems, the main types of sewer wells, their parameters and requirements for structures will be considered.

Sewer systems of private houses

In the arrangement of suburban areas, autonomous sewer systems are often used, which are distinguished by the presence of a large number positive qualities. Some systems are more cost effective than using a central manifold, while others are the only possible solution sewer problems.

For the normal functioning of the external sewage system and the provision of quality service, the design of the system must be arranged in accordance with the norms and rules displayed in the relevant documents.

The installation scheme of the sewer system and its operation largely depend on factors, which include:

• topographic indicators of the selected territory;
• types of soils located on the site;
• the presence of water sources near the site;
• layout of engineering underground networks that are already present on the territory.

The sewerage device can be quite simple: simplest design consists of a single piece of pipeline that transports wastewater to a pit or septic tank located outside the building. You need to know how far from the house to make a septic tank. The simplest septic tank can be made from car tires stacked vertically on top of each other: drains will still be filtered, and solid fractions are periodically pumped out by a sewage machine. This design is well suited for installation in suburban or small urban areas. In order for the sewer to work normally, it is enough for it to provide a constant slope and periodically pump out.

It is much more difficult to arrange a sewer system in a site that has a difficult terrain, or where a source is located. drinking water. In this case, the sewage system must comply with the sanitary requirements that apply to septic tanks or waste storage tanks. In addition, the device of the system can be complicated by connecting to it drainage system and storm drainage. See also: "".

This design consists of several separate pipelines, so it will require a large number of wells. To ensure the operability of the system, you need to either contact the specialists, or carefully study all the nuances associated with the requirements for sewage.

Types of sewer wells

The main document that defines design features sewer elements and the distance between sewer wells - SNiP 2.04.03-85 “Sewerage. External networks and structures”. The document contains a large number of requirements, but there is no need for owners of private houses to study them all - it is enough to deal with the problem of local drainage (read also: ""). The main thing you need to know is that any sewer system requires intermediate wells, and they will be installed depending on various factors.

Distance between manholes according to SNiP

Manholes should be installed in such situations:

• in the presence of an extended pipeline running in a straight line;
• if there are turns or bends in the pipeline, as well as when the diameter of the pipes changes;
• in the presence of branches of the structure.

The function of manholes for sewers is to monitor the system and the ability to gain access to its interior for maintenance.

Determines the distance between the SNiP sewer wells, and according to it, the following rules must be followed:

• with a pipe diameter of 150 mm, wells are installed every 35 meters;
• 200-450 mm - 50 m;
• 500-600 mm - 75 m.

A further increase in the diameter of the pipes allows you to increase the maximum distance between the sewer wells even more. However, the likelihood of such a design appearing in a summer cottage is extremely small, because the volume of effluents produced by 3-4 people does not require wide pipes. Use of pipes large sizes can be justified if absolutely everything passes through the sewer wastewater: and precipitation, and water from the bath, and directly waste from a residential building.

As a rule, when arranging private sewer systems, pipes with a diameter of 100 mm are used. When using them, the distance between the sewer wells is defined by SNiP as 15 m. In the event that the sewer does not have bends, branches, and the diameter of the pipeline does not change throughout its length, then the distance can be increased to 50 m.

Rotary wells for sewerage

This type of wells is absolutely identical to inspection wells in its purpose and design, with the only difference that rotary wells are mounted in places where the direction of the pipeline changes. Sharp bends with large angles of rotation are usually the areas most likely to become clogged, so they need to be given Special attention. It is this function that rotary wells perform.

The distance between the rotary sewer wells is usually calculated based on the length of the straight sections between the bends of the pipeline. If the pipeline section is longer than specified by the regulatory document, then it must be equipped with inspection wells to ensure a sufficient level of control over the operation of the system.

Drop wells

Sewerage installation on site complex terrain- it's pretty tricky. If the territory has a noticeable slope, then the slope of the pipeline will also be appropriate, which is absolutely impossible to allow: wastewater moving from high speed, will gradually settle on the walls of the sewer system, thereby clogging it and rendering it unusable.

Regulatory documents in this case speak of the need to install differential wells, which are installed in steps and compensate for the high speed of waste transportation, saving the structure from blockages (more: "").

In this case, SNiP does not determine the specific distance between sewerage wells, but imposes some design requirements:

• firstly, the height of one drop must be less than three meters;
• secondly, with drops up to 0.5 m deep (when using pipes with a diameter of up to 600 mm), drop wells can be replaced by inspection wells using drains.

You should always remember that any sewer system ends with a spillway point, in which the final well is necessarily located, requiring an inspection hatch.

Other regulations

In addition to the standards described above, which are often a problem for owners of private plots due to their inaccessibility, there are others that must also be followed in order to avoid problems with the functioning of the sewer in the future. For example, the minimum distance from the sewer well to the building should be 3 m, and the maximum - 12 m, regardless of the type of well used. The distance from the house to the sewer well is quite important indicator which must be observed. It is important to consider the distance from the cesspool to the well. In addition, it is important to always remember the existence of sanitary standards that determine the removal of elements of sewer systems from reservoirs, water sources, vegetable gardens and orchards.

Conclusion

Installing a sewer system on your own site is not a big problem. All installation work related to laying pipelines and arranging sewer facilities are quite simple, and any homeowner can do them (read also: ""). About all types of work, you can find other articles on this site, and then everything will become very clear.

Wells play an important role in the operation of the sewer system. This is a necessary structure, without which the system will not function properly, or even completely clog. Sewer wells are not randomly located on the track, but have their own place. And each of them does their job. The number of installation of wells depends on the length of the route, turns, drops, as well as the diameter of the sewer pipes. The existing SNiP document clearly indicates the device, purpose, as well as the distance between the sewer wells. Let's take a closer look at all types of sewer wells, their purpose and their installation locations.

Inspection sewer wells

This type of wells serves to inspect and control the sewer system. They also clean the pipeline in case of blockage. Inspection wells are installed on a long straight pipeline, bends, at the points of connection of the side sleeves, as well as at the point of change in the diameter of the pipe or its slope. The distance between installed wells for pipes of different diameters is calculated, guided by the SNiP document. On a straight line with a pipe diameter of 150 mm, the distance between the wells should be 35 m. For pipes from 200 mm to 450 mm, the distance will be 50 m. There is probably no point in listing larger pipe diameters. They are mainly used in central sewer systems, with a large volume of wastewater. As you understand, with an increase in the diameter of the pipe, the distance between the manholes increases. This is because the pipe larger diameter has less chance of clogging. There are cases when the distance can be increased up to 50 meters on a flat track with the same pipe diameter and without side arms. In everyday life summer cottages and private yards for sewerage use PVC pipes with a diameter of 110 mm. On such networks, the distance between the wells can be reduced to 15 meters.

Rotary sewer wells

This type of well performs the same functions as a viewing well. Has the same device. And it got its name due to the fact that it is installed at the turn of the highway. Every turn or bend in a pipeline can become a blockage point. In order to have access to clean this section of the sewer, wells are installed at all turns and bends without exception. If the rectilinear distance between the rotary wells is large, then additional manholes are installed in this area.

Overflowing sewer wells

This type of well is installed in problem areas of the sewer, where it is impossible to maintain the correct slope of the pipeline. Take, for example, a large slope. In such a place, the correct slope of the pipeline cannot be maintained. And this entails a quick discharge of wastewater, which will not have time to take solid accumulations with them, and the pipe will clog over time. Therefore, in such places, overflow wells are installed according to a stepped system. The distance between such wells is determined individually and depends on the slope, but the difference should not be more than 3 m. If the sewer has a pipe diameter of up to 600 mm and the difference is less than 50 cm, it is possible to replace the overflow well with a viewing well equipped with a drain.

At the end of the sewer system, the so-called final well is necessarily installed. This is the place where all wastewater from the sewer is drained. It can be both filtering and accumulative. But the bottom line is that in front of this well or in front of a tie-in to the city highway, a control well is installed at a distance of 1.5 m.

Distance from the building

At the exit from the building of the sewer system, the first well is necessarily installed. According to the norms, it should be located at least 3 m from the wall of the building in the direction of the flow, but not more than 12 m. Basically, the length of the outlet of the manhole from the wall of the building should not be more than 8 m. If this distance cannot be maintained, then an additional well.

When building a sewer, maintaining a distance between wells, do not neglect sanitary standards. Remember that in addition to the correct distance between them, the distance of the well from the reservoir, drinking spring, garden plantings must be maintained. The distance to the water well depends on the material of the pipe from which the water supply is made. But in any case, at least 5 m. If it is a drain well, then it is located at least 10 m from the water supply.

As you understand, any sewer, built according to all the rules and regulations, eventually requires cleaning and maintenance. Therefore, so that you do not have to open the entire network when the pipes become clogged, install the wells correctly. Having withstood all distances in accordance with established standards, you can always get to the problematic section of the pipeline and carry out an audit.

In the absence of centralized water supply, the sources of water are underground interstratal waters. For free access to water, a mine well is usually arranged on the site. Subject to technology, it gives good water, durable and easy to operate. One of the important conditions for the correct placement of a water source on the site is compliance with optimal distance from the well to the septic tank, other wells and other structures.

Proper location of the well on the site is a difficult engineering task, which is underestimated by inexperienced owners country houses. In order for the operation of water supply and sewerage systems to be trouble-free, it is necessary to understand even before the start of work that there are norms and rules, non-compliance with which will lead to problems in the future.

Placement and Depth Selection

When building a well, you need to determine its estimated depth and the number of rings. If the site is new, and construction has not yet begun, the search for water should begin with a survey of the sources used by the neighbors.

How to find the right location for a well

To find, you need to find out the following information:

• The depth of wells and wells in neighboring areas;
• Volumes of water loss;
• terms of use;
• Features of operation.

In the absence of neighbors, the task becomes more complicated. Then it is recommended to use one of the methods for determining the source of water. The most popular of them:

• dowsing;
• Hydrogeological indications;
• Local displays of water.

None of them will give a 100% guarantee of the reliability of the data. However, you should know that it can be carried out at a certain distance from water sources in neighboring areas. Otherwise, the water from them may simply go into the newly formed wells. In addition, this method is quite expensive and is more suitable for undeveloped areas.

Criteria for choosing a site on the site

Careful choice of location is a prerequisite for creating a reliable and high-quality source of water supply. This approach will eliminate the risk of receiving water that does not meet sanitary standards. When choosing a place, they are guided by such criteria as:

• Convenient location on the site;
• Distance between wells and objects of use;
• Distance from pollution sources.

What you need to know about the distance of the well to the foundation

The problem of the location of the well on the site is especially relevant for owners of small plots. The building should be as comfortable as possible. To do this, it is positioned so that it is possible without special efforts organize the supply of water to such buildings on the site as a house or a bathhouse, as well as to a garden. Usually, the highest place on the site is chosen for the well; cesspools neighbors.

What is pumping station you will learn for the well.

In addition, the influence of the mine on the neighboring building should be taken into account. For the well, choose a place closer to the house. This is due to the peculiarities of the organization of water supply: supplying water to a house over long distances is an expensive pleasure. Wells can be built even inside the house. Usually, at the same time, a shaft for a well is first arranged, and then a foundation pit is dug. In this case, the type of soil and the topographic conditions of the site should be taken into account.

Another thing is when the house is already ready, and the well is only in the plans. Houses on shallow foundations may suffer from the proximity of well shafts. It is not necessary to arrange wells in the immediate vicinity of such buildings. Particularly dangerous in this regard are shallow strip foundations on clay. Here it is worth considering the depth of the well. More trouble for buildings are fraught with shallow mines. Water can wash away the foundation.

Wells can be located at a distance of at least 3 m from the foundations of buildings. This norm is spelled out in SNiP 30-02-97.

The minimum distance to buildings for keeping animals is 4 m, to other buildings - 1 m, to trees - 4 m, to shrubs - 1 m.

What should be the distance between wells

The device of a local water supply system on the site should be carried out in accordance with the project. If it clearly states how many and what structures will be required for the system, then many questions disappear by themselves. The documentation should also include data on the exact distances from the well to the well.

Water well drilling technology is described.

Owners of country houses often build a water supply system with their own hands, while the project is not drawn up. Therefore, we need instructions that will tell you how to calculate the location of the wells.

When creating a home water supply, one well is not enough; additional tanks are needed. They are necessary for network maintenance, as well as troubleshooting.

The number of shafts and tanks depends on:

• Distances of the well to the foundation of the house;
• The presence on the site of other buildings, pipelines and other structures;
• The complexity of the relief, taking into account the differences in height.

Plumbing device with a well near the house

The best and easiest option is one manhole. It is suitable for areas where the drinking well is as close as possible to the house. It is located at the entrance of the pipeline to the building.

How to choose a pump for a well will tell you.

Calculations are made taking into account the fact that the external piping is performed 20 cm from the wall. If the diameter of the well is 1 meter, then the distance from its axis to the wall will be at least 70 cm.

Plumbing device with a well remote from the house

The situation becomes more complicated when the source of drinking water is significantly distant from the house. In this case, the construction of several observation tanks will be required. The maximum distance between the wells of the water supply is 15 m. For sewer inspection structures, this norm does not differ.

Check out the dimensions of concrete rings for wells.

If necessary, change the direction of the pipeline, build a rotary well. The connection of all nodes should be as accurate as possible. In these places blockages occur more often than others.

In areas with height differences, it is necessary to change the depth of the pipes. To do this, build a differential structure. The entire plumbing system is laid at an angle to the well.

Distances from this structure to other components of the water supply system are regulated solely by the features of the site relief. To optimize maintenance costs and save money on the device, both auxiliary structures can be combined with manholes.

Sewer

In order for the water supply to fulfill its function, it is necessary to observe the distances from the sources of pollution to the well with drinking water and between the elements of the sewer system of the site. These norms are spelled out in SNiP 2.04.03-85. At the same time, structures are taken into account not only on their own site, but also on neighboring ones.

Distance between sewerage and septic tank

Water structures should be built at the maximum distance from landfills, industrial facilities, septic tanks, collectors and other sources of pollution. The minimum distance from the source of drinking water to wells with drains and cesspools is 50 m, buildings for livestock farms is 30 m. The distance from the septic tank to residential premises is 7 m.
