Today, many people are thinking about making a sewer well. This desire arises especially often during the construction of a new home. In order to do everything, you do not need to contact any employees. You can make a sewer well with your own hands, thus saving your money.

What needs to be done first?

Of course, choose a place where everything will be located. Here you need to take into account not only some of your personal preferences, but also sanitary standards. You need to understand that later you will need to lay pipes. Study SNIP thoroughly before starting work. There should not be a distance of more than 15 meters between two inspection wells. Be sure to look at what distances still need to be maintained. Please note that there should not be any rotary pipes without equipped rotary wells. And without maintaining distances, it may happen that drinking water will enter the system.

Carrying out calculations

Many people wonder how to make a sewer well by hand. But there is no universal answer here, it all depends on your specific case. For example, if you choose a large savings option, you can’t go wrong. It won't have to be cleaned very often. And the suction pump will need to be called from time to time. A sewer well made of rings is also relevant.

Much depends on the number of people living on the site. For example, each person should have about 150 liters of waste water. If this is a family of four, then you will need about 700 liters. But here everything is individual, depending on what household appliances you will use.

What sanitary standards must be taken into account?

The primary decision is whether the well will be airtight. It all depends on the volume. If the flow is more than one cubic meter, then the answer should be positive. Otherwise, you will have to carefully work on the cleaning system. Otherwise, harmful bacteria will get into the soil, and from there directly into the food.

If you are making a sealed version, be sure to concrete the walls. The same goes for the bottom. After the concrete comes a layer of sealant. But it can be simplified this process using a specialized container. It should be understood that the sealed option will require much more serious investment in materials. In addition, you will have to pay money for waste removal. So think carefully. It is possible that you suitable option with a small drain.

How is a sewer well created in a private house?

Be sure to check it out detailed photos, videos and drawings that will help you navigate without any problems. First, dig a hole of the size you need. If it is large, then you can order an excavator. Special equipment will save you a lot of time and nerves. Keep in mind that about 40 cm of the bottom will have to be covered with crushed stone. This is important in order not to pollute the wastewater. This process can not only cause terrible diseases, but also cause fines.

Now choose the materials for making the well. It can be plastic, wood, concrete, bricks. Now they should arrange the bottom. You can do everything on a slight slope especially for the future hatch. After the walls are installed, a sewer pipe is installed. The walls need to be covered with sealant. The ceiling with the hatch is installed, and the top is covered with waterproofing material. The ventilation pipe is installed at a distance of approximately 60 cm above the soil. Ventilation cannot be ignored. It is designed not just for better cleaning, it is an integral safety requirement.

What to do next?

Now you can test your new drain. At this stage, it is advisable to consult with a specialist how often you will have to call a sewer truck. No matter how small your well is, you will still have to use the services of workers sooner or later. If after construction you feel unpleasant odors, then simply use different chemical or biological means. True, they have one drawback. They are ineffective at temperatures of +5 degrees Celsius. Happy construction!

A do-it-yourself sewer well is important element arrangement of private or country house, especially if it is located near the security zone. For the construction of such structures, there are standards that must be followed. In general, the production of sewer wells various designs And for various purposes does not cause any particular difficulties, and the well can be made by hand, which will significantly save money.

When building your own sewer system at a dacha or in a private house, wells play an important role. At proper organization Such a system will require a special scheme, providing for several different well structures.

The main types of sewer wells are:

inspection (control) type: placed on straight sections to monitor the condition of the system;
rotary type: formed at the bend of the pipe to allow cleaning of such a bend in case of blockages, since turns are a rather dangerous area in terms of accumulation of debris;
nodal view: for monitoring joints and wiring of the sewer system;
drop view: installed as needed when there are significant differences in elevation along the route;
storage and filtration wells: the final element of the sewer pipeline for wastewater accumulation and treatment Wastewater before being discharged into the soil.

Wells can be rectangular (square) or round in shape. Sewage well with your own hands can be made from reinforced concrete, plastic, brick, wood or other available materials.

Structures made from reinforced concrete well rings are widely used.

Well location The correct location of wells is determined by SNIP standards, which is associated with the sanitary safety of residents. The distance between inspection structures should be no more than 15 m, and the first such pit should be located no closer than 3 m from the house. Filtration and storage structures should be placed away from residential buildings. The risk of contamination must be controlled especially strictly.

drinking water The filtration system must be moved away from the drinking source to a distance of over 30 m. When installing storage tanks, it is important to provide for the possibility of free access for vacuum trucks. Figure 1 shows approximate diagram

location of the well system. All sewerage elements should be located taking into account comfortable living - the absence of foul odors. When placing them, it is recommended to take into account the wind rose. (Fig. 1. Layout of sewer wells) Dimensions determined by the number of residents and taking into account guests. It is customary to calculate the required volume based on the condition of 0.7-0.8 m³ per person, i.e. for an average family of 3-4 people, a sufficient volume is 2.4-2.5 m³. In this case, the need to avoid overfilling the well should also be taken into account - the design level is set below the surface level by 0.6-0.8 m. Inspection wells are made of a significantly smaller volume. Their sizes are mainly determined by the ease of sewer maintenance. The differential type is installed if the height difference is more than 0.5 m.

It must be remembered that any wells deeper than 3 m require increased tightness of the bottom area, so it is often impractical to make them so deep.

Necessary tool

When building sewer wells with your own hands, you will need the following tools:

Bulgarian;
perforator;
electric drill;
sledgehammer;
bit;
chisel;
shovel;
Master OK;
putty knife;
hammer;
hacksaw for metal;
hacksaw;
paint brush;
construction level;
roulette;
plumb line;
metal ruler.

Concrete well

Wide use concrete wells due to their ease of installation and high reliability. They are constructed from reinforced concrete well rings. The most commonly used rings are standard rings with a diameter of 1 m and a height of 0.9 m. A ready-made ring is also installed on top. concrete slab with a hatch closed by a metal lid. Figure 2 shows a design of such rings. (Fig. 2. Well made of concrete rings)

Making a reinforced concrete system with your own hands is carried out in the following order:

Digging a hole with a depth of 45-55 cm greater than the depth of the well and a diameter of about 1.2-1.5 m.
A cushion made of a layer of sand and crushed stone about 25-30 cm thick is placed at the bottom of the pit.
Poured concrete bottom about 10 cm thick with reinforcement with steel wire or rods with a diameter of 6-8 mm. The level controls horizontality.
Concrete rings are being installed with the joint sealed cement mortar. As you install the rings with outside they are coated bitumen mastic to ensure waterproofing.
An entry hole is punched at the required height sewer pipe, and after its insertion the joint is carefully sealed.
Installation of the top concrete slab.
Gap with outside rings are filled with soil using a tamper.

Plastic construction

Modern plastic containers for creating various tanks can significantly simplify the manufacture of a sewer system. They are available in different sizes and shapes. You can choose vertical or horizontal installation tanks.

Plastic structures have a number of advantages: high strength, tightness, operating temperature range from minus 55 to plus 80 degrees, ease of installation.

When installing such tanks, lifting equipment is not required. The design already provides a sealed sewer pipe entry, which simplifies installation.

Installing a plastic container involves only a few operations: digging a pit to the size of the container, filling a bed of sand and crushed stone, installing the container, connecting a sewer pipe and filling the external gap with soil with a tamper.

Filtration system

All sewer wells must have the main property of tightness, in addition to the filtration structure. The purpose of such wells is to purify the wastewater entering it and then discharge it into the soil. Filter wells are being constructed as the final element of the treatment system. This system additionally includes 1 or 2 septic tank treatment, where chemical and biological wastewater treatment is carried out.

Only after in-depth cleaning can the sewer pipe be connected to the filtration well. The fact is that this last element only works as a natural filter for mechanical suspensions and impurities. The structure of the filtration well is shown in Fig. 3. Fig.3. Filtration design.

When constructing such a structure, a filter of crushed stone and gravel is created at the bottom of the well shaft. The bottom is concreted only under the walls of the rings in the form of a foundation. There must be a hole in the center of the bottom for draining water. The filter is manufactured in the following order. The hole for the well is dug 100 cm deeper than the height of the well shaft. A layer of sand (no more than 10 cm) is poured into the bottom of the pit and crushed stone and coarse gravel are laid. You can use broken brick and stone.

The thickness of the stone layer is about 1 m. Then you can make a concrete foundation in the form of a ring with a central hole of at least 50 cm. After this, reinforced concrete rings are installed in a similar way to a storage structure.

One more condition must be met - the height of the sewer pipe entry must be raised from the bottom (filter) to a height of at least 50 cm. This is important so that the incoming water jet does not wash out the filter. Another important nuance: the filtration backfill of crushed stone should also be on the outside of the concrete rings. At the bottom of the first ring in the wall, it is recommended to punch additional drainage holes at a distance of 10-15 cm from each other.

The well system is an important and responsible element own sewerage system in a country or private house. Its construction must be carried out taking into account sanitary safety requirements and ensuring reliable tightness.

Do-it-yourself sewer well - rules and methods of construction If you are building new house or decided to improve the old one, one of the main tasks will be the installation of communications that ensure comfortable living. Since it is impossible without a properly designed drainage system, the question will arise - how to make a sewer well with your own hands. If you want to save money and do not plan to involve a contractor in this work, then before starting it you should study all the rules and regulations for installing a sewer system for a private home. They are contained in SNiPs, which are quite difficult to understand for people not involved in the construction business, so we suggest that you simply read this article carefully. Rules for constructing sewer wells Before you start doing anything, you need to decide on the location for the well, its volume and depth. To do this, you will need to draw at least a primitive sewer diagram from the exit from the house to the well, which will also help you calculate required amount required materials. Sanitary requirements When choosing a place for sewer septic tank or a cesspool, first of all, the location of the water intake points should be taken into account. And not only on your own site, but also on neighboring ones. If contaminated wastewater leaks into an aquifer and from there into a well, it can cause serious illness. The type of soil also matters - how permeable it is. The instructions require compliance with the following distances between sewer and water wells: When sandy soils– at least 50 meters; For clayey ones - at least 20 meters. Having determined the places on your site that meet these requirements, you can decide which of them is more convenient to locate the structure, taking into account the distance to the house and the position of the outlet point of the internal sewer system. Technical requirements The first thing you should know is that the structure cannot be placed closer than three meters from the foundation of the house. The ideal distance is 8-12 meters in a straight line. But it is not always possible to withstand it: the layout and topography of the site may not allow this. In such cases, when building a sewer well with your own hands, you must comply following rules : If the length of the sewer pipeline is very long, inspection wells must be installed on it. The first one is at a distance from 3 to 12 meters from the exit from the house, the subsequent ones are every 15 meters. They are necessary to control the operation of the system and facilitate its cleaning if necessary. If the pipeline has turns or is connected into one common pipeline of two or more outlets, a rotary well is installed at such nodes. It is also used as an observation room. If the terrain does not allow laying a pipe with minimum slope , a differential well is being built to ensure the permissible speed of wastewater movement. It is important! It should be explained why the speed at which sewage moving through pipes. If it is very small, a plug may form in the pipe, which will clog the lumen. If it is too large, the liquid will drain quickly, not having time to carry the solid fractions with it, which again will lead to the formation of congestion. Water flows into the sewer well by gravity, which is ensured by the slope of the pipe. With a diameter of 100 mm, it should be 2 cm per linear meter, but if the diameter is 50 mm, the slope is one and a half times greater - 3 cm per linear meter. That is, the further the well is located from the outlet, the deeper it should be, since the entrance to it will be lower. Having drawn a sewerage diagram to scale with neck, the difference lies in the design of the bottom. So: The storage tank is designed to collect sewage, which, as it fills, is pumped out by a sewer truck (sludge pump) and removed. It must be completely sealed. In the filter, the liquid seeps into the lower layers of the soil, where it is gradually purified, passing through its layers, so it is made without a bottom and installed on a filter layer of gravel, broken brick or crushed stone. It has to be pumped out less often. Attention! At high level groundwater, the installation of a filter well without preliminary wastewater treatment is unacceptable. There is also a more advanced design of sewer wells - a septic tank, in which stepwise wastewater treatment occurs, but it must be designed and installed by specialists. How to build a sewer well yourself Many private developers decide to do the sewer installation themselves, since this is not the most difficult task, and the cost savings are decent. Stages of work Since the average depth is 4-6 meters, to reduce labor costs and save time, it is better to dig a foundation pit using an excavator. The diameter of the pit must be greater than the outer diameter of the well (or its linear dimensions for a rectangular or square shape) at least 30-40 cm. If you decide to make a storage tank from reinforced concrete rings, rubble stone or brick, the sequence of work is as follows: Digging a trench for the pipeline and constructing a pit; Preparing the base by filling the bottom with a layer of crushed stone and compacting it; Filling the bottom with concrete; For reference. You can do it easier and lay a finished reinforced concrete slab on the bottom of the pit. Installing rings or laying brick walls. The seams between the rings are sealed with cement mortar, and brick walls are also plastered with it; Inlet device for input to prevent the accumulation in the well of explosive gases released during the decomposition of organic matter. It should rise above ground level by at least 60-70 cm. A filter well is built in the same way, with the only difference that the bottom under it is not completely poured, but only under the walls, so that they rest not on the ground, but on concrete base. In addition, drainage holes are made in the lower part of the first ring, and a backfill of crushed stone is made on the outside. In the case of brick construction, holes are left immediately in the lower rows of the masonry. Plastic wells It is much easier to use ready-made containers made of durable and frost-resistant plastic. Perhaps the price of the products themselves will be higher than the cost of reinforced concrete rings, but you can save effort and time, as well as money, without calling a manipulator to install heavy and bulky structures in the pit. Plastic wells are lightweight, and you can handle it yourself. They are produced in different volumes and diameters, with ready-made inlet holes for pipes, so you will not have any difficulties with their selection and installation. In addition to light weight and ease of installation, plastic wells have the following advantages: Absolute tightness, which will allow you not to do insulation work and not worry about possible leaks; Resistance to both very low and high temperatures ; Resistance to aggressive environments; High strength and, as a result, durability. They will not require any repairs throughout their entire service life. Final work The finished well is completely covered with earth to avoid freezing. Only the hatch remains open. There should always be free access to it, and there should be access roads for the suction pump nearby. All that remains is to think about how to fit this element, necessary for a comfortable life, but not too attractive, into the landscape of the site, especially if it is located in an open place. It's easy to do. Now on sale there are special decorative covers for well hatches in the form of a large boulder or a removable flower bed. Can be arranged around the hatch alpine slide or install lightweight wooden or wire frame for. If we talk specifically about the installation of individual sewerage on the site, then the easiest way is to assemble it from finished products – plastic pipes, connecting elements and different types wells.

Wells for sewerage – necessary thing in every urban area. Without sewerage there would simply be nowhere to discharge wastewater. Today, the construction of sewer wells has been worked out to the smallest detail and is enshrined in SNiP. This document contains standards for arranging a container for water accumulation and conducting installation work. The places where sewage pits can be placed are also documented. Regardless of where the structure is located, its arrangement must be carried out in accordance with established rules.

What does sewerage consist of?

Construction of a sewer well - actual question when conducting construction work or arrangement of a sewerage system on certain area terrain. The structure of a sewer well requires the following parts:

The bottom of the container is the lower part of the entire device, in direct contact with wastewater.
The shaft is a part of a structure almost two meters long, an internal cavity in which, as a rule, repair work is carried out.
The working chamber is part of the system in which repair work related to pipes is carried out.
The neck is the upper, visible part of the container with a hole at the top intended for the lid.
The hatch is the closing part of the structure, the cover of the waste pit, which prevents foreign objects, animals or people from entering the container.

This design is general and may differ slightly in some versions. A well cannot be constructed according to an individual plan; it must comply with the standards established in SNiP.

Types of sewage tanks

Types of sewer wells include several types of structural design of the container for water drainage. Depending on the principle of construction of sewer wells, structures can be divided into several types.

Variable

Differential sewer wells are structures that are installed in places where there is a need to change the intensity of wastewater flow. Drop wells can be installed in certain situations:

if there is a risk of change in flow rate;
if the sewer crosses the highway;
when laying another pipeline;
Also, a drop well can be installed if there is partial flooding of the place where the water exits.

The operating principle of a sewer differential well is based on special design, which redirects wastewater flows.

Observation

Inspection tanks are structures that are designed for inspecting the sewer system, as well as for carrying out repair work sewer or water supply. This design has no analogues today. Installation of inspection-type sewer wells is provided in the following cases:

in places where there is a change in pipe size, slope and diameter. Such places are the weakest and are often subject to various breakdowns;
in an area where there is a change in wastewater flow;
at the point where the pipeline branches into several small pipes;
in areas that, in the opinion of specialists, require special monitoring.

Inspection structures are usually placed in such a way that the distance between sewer wells is at least 15 meters. If the pit is installed on the territory of a private house, then the distance from the structure to the house should be at least 3 meters, but not more than 12.

Rotary

A rotary sewer well is a structure that is installed directly at the turning point of the main sewer system. The distance between sewer wells in this case is determined only by the location of the pipeline turns.

Nodal

Junction structures are structures that are installed in places where wide pipelines branch.

Direct flow

Direct-flow tanks are structures that are mainly intended for flushing sewer pipelines. Such structures are installed in different places, depending on which several types of direct-flow structures are distinguished:

linear - structures necessary for periodic inspections and flushing of networks;
flushing - structures that are installed, as a rule, at the very beginning of the water supply system for flushing it;
control structures - structures that are placed in places where streams of water that have undergone purification are discharged. Such structures are necessary to monitor the quality of passing water.

In various places, sewage systems must be installed with the inclusion of waste containers in the system. It is with the help of these structures that the entire system is monitored, flushed and repaired. Even if sewerage is installed in a private house, at least one well must be on the site. Otherwise, the owner of the site simply will not be able to control the operation of the sewer system and, if necessary, repair it.

How to correctly calculate the size of a sewer pit?

How to make a sewer well? This question is especially relevant if the owner of a private house and plot decides to make a sewer well with his own hands. Of course, it is quite difficult to make a well without the participation of specialists, however, it is still possible. The main thing here is to follow all established rules in order to sewer system subsequently it functioned normally and did not cause problems.

Before you begin installing a sewer well, you need to determine its location and make all the necessary calculations. The first parameter that must be taken into account is the volume of the waste pit. This indicator is calculated depending on the number of people living in the area and the approximate water consumption. For example, a standard family with two children uses up to 1000 liters of water per day.

According to accepted standards, a drain with a bottom area of one square meter can provide water output in the amount of one cubic meter. It is important to take into account the fact that the working volume of the structure must correspond to at least triple the rate of water flow per day. Therefore, the volume of a well for a family with two children should be at least three cubic meters.

Knowing exactly what volume of construction is needed on a specific site, you can calculate required diameter well. The average depth of the pit is 2.5-3 meters. When calculating the parameters of a well, it is important to calculate the distance from the well, or rather its working part, to the drain pipe. This is quite simple to do; you need to subtract the length of the drain pipe, which is 70 centimeters, from the depth of the structure. Next, the volume of the well is directly calculated, which consists of multiplied data on the depth of the hole and the area of its bottom.

Types of arrangement of the bottom of a well

If you are making a sewer well with your own hands, you must also first select the type of pit bottom. The most common and popular option is a pit with a round bottom, since it is the easiest to use and maintain, however, in addition to this option, there are other types of well bottom.

The most commonly used varieties are structures with round and quadrangular bottoms. The last option can be made in the form of a square or rectangle. Before you build a sewer well with your own hands, you need to calculate the diameter and depth of the hole, taking into account the walls that will be laid to strengthen the structure.

Installation of protective structures inside the pit can be made of the following materials:

bricks;
reinforced concrete rings;
concrete pouring.

The distance to the bottom is calculated solely taking into account all design features and strengthening attitudes.

How to install a sewer well yourself?

The main argument in favor of building a sewer system on the site with your own hands is the significant cost savings. If a container made of brick, concrete rings or rubble stone was chosen as a structure, the following sequence of actions must be followed:

first of all, a hole is dug for the storage tank, as well as a trench for the pipeline;
then the base of the pit is prepared. As a rule, for these purposes, crushed stone or other similar material is poured into the bottom of the pit;
after this, the bottom is filled with concrete mortar;
Next, the walls of the structure are strengthened. To do this, concrete rings are installed, brickwork or stone masonry. In this case, all joints must be covered with cement mortar. In case of installation brick wall additional plastering of the walls is also carried out;
then the inlet for the drain pipe is installed and equipped. After installation, all holes must be sealed;
the outer walls are insulated using tar or fatty clay;
then the soil is returned to its place and compacted;
a floor slab and a hatch are installed on top of the well;
V last resort The ventilation pipe is being installed. This part of the structure is necessary in order to remove gases accumulated inside, resulting from decomposition. organic matter. The accumulation of such gases is dangerous due to the possibility of explosion.

The owner, as a rule, chooses the distance between sewer wells on a private plot independently depending on the area of the territory, the location of the sewerage system and the volume of wastewater. However, when carrying out independent work Still, do not forget about work standards.

Owners of private houses most often have to independently install local treatment facilities on their site. It is cheaper and easier to install sewer wells in the form of a regular cesspool or a sealed storage tank. A well-designed treatment or storage point will do the job perfectly. Do you agree?

Here you will learn what materials are used in the construction of treatment facilities and storage tanks for independent sewerage. We have described in detail the technologies for constructing typical sewer wells. Taking into account our recommendations, it will be easier for you to decide on the best option in terms of price and effort.

Often, there is simply no centralized sewer system in the private sector with low-rise buildings. And it is necessary to get rid of household waste, but not to pour it on the ground. For this purpose they are building autonomous system sewerage system, including internal and external parts.

The in-house sewer system collects wastewater from plumbing fixtures, and its outer part is intended for its disposal or accumulation for subsequent pumping by sewer trucks. The receiving wastewater on the street is the end point of the local treatment system.

If there is no general sewerage network in the village, then you cannot do without a cesspool or sewage storage tank near a private house

Fecal wastewater in the sewer well is clarified, resulting in the formation of partially purified water and suspended matter. In case of cesspool the first is drained into the ground, and the second is decomposed by microorganisms to the state of sludge that is safe from a biological point of view.

If the option with a storage tank is selected, then the sewage is simply collected in sealed container, and as it fills, it is pumped out using a sewer truck.

The distance between the drainage bottom of the cesspool and the groundwater layer must be at least a meter, otherwise the purified water will have nowhere to go

Requirements for the construction of such structures

All sewage systems must be installed according to a pre-developed plan, which indicates the layout of all elements of the system and the building materials used. Its outer part in the case under consideration consists of a pipe draining away from the house and treatment plant.

The design and installation of sewer wells is regulated in the following regulatory documents:

If you do not comply with the requirements specified in them, then the sewerage system after assembly may simply be inoperable.

When choosing a location for a treatment structure on a site, do not forget about the need to leave free access to it; even a drainage cesspool must be cleaned from time to time of accumulated sludge

Structurally, the sewer well consists of:

necks with a lid or hatch;
shafts in the middle part (working chamber);
bottom (draining or sealed depending on the installation option chosen).

Even similar elements of this design can vary greatly in size and shape. Here a lot depends on the material of manufacture and design features treatment plant, as well as tank volume.

What can a sewer well be built from?

A well structure can be made from a variety of building materials.

When choosing optimal option must be taken into account:

Climatic conditions of the area (maximum possible and average temperatures, total amounts of rainwater and snow).
Soil characteristics (freezing depth, composition and groundwater level).
Features of the site's relief.

If the soils are very heaving, then the sewer well should be made of the most durable building materials. And for wet soils you will have to select the most moisture-resistant option.

The most inexpensive and fastest to install is a structure made of reinforced concrete rings, however, to install them in a dug pit you will need to order a crane

You can easily make a sewer well with your own hands from:

brick and stone;
monolithic concrete;
reinforced concrete rings;
ready-made plastic structures
old car tires.

Cheapest at self-installation Either a septic tank assembled from factory-made or home-made concrete rings will cost.

But in the first case you will have to tinker with the masonry, and in the second you will need lifting equipment. Lower the heavy ones concrete products It is not recommended to put them into the pit by hand; if they are torn down or hit hard, they may break.

It will only be possible to make a sewer well with drainage from brick; ensuring complete tightness of brick walls is extremely difficult and expensive

The concrete monolithic option will require arrangement of formwork and preparation of mortar. If the latter is ordered already mixed in a concrete mixer, this will lead to a serious increase in the cost of work.

Structures made of plastic (polyethylene or PVC), fiberglass and polymer sand are quite expensive. But they are durable and extremely easy to install yourself. Such products weigh little, a couple of people are enough to install them.

Used tires will make a very cheap sewer well. They cost pennies at a tire shop, but you can collect tires at a landfill for free. But here the problem is the same as in the case of brick.

It is extremely problematic to make such a structure airtight, and it is almost impossible to repair it. You can make them out of them, but you can’t store them anymore.

Selecting the location and volume of the tank

When installing a sewer well, you must observe whole line sanitary and construction requirements. Failure to do this increases the risk of biological contamination. The situation can lead to an outbreak of infections, which threatens the owner of the cottage with serious problems.

The installation of a sewer well should be done away from:

fruit-bearing trees and beds 3 m;
foundations of buildings on personal plot at 4–5 m;
roads and underground engineering communications(gas, water, electricity) 5 m;
wells for drinking water and reservoirs 30 m.

A slight deviation from these figures is possible only when installing a sealed storage tank or when constructing a cesspool with thick concrete walls with reliable external waterproofing.

In the case of an absorption well, water that has passed through a multi-layer filter of sand and gravel must enter the underlying layers of soil away from buildings, communications, drinking wells, all types of reservoirs and private pools.

Distances should be maintained so as not to change the composition groundwater V the worst side, do not pollute water bodies with insufficient cleaning and do not wash out the underlying base from under building structures and engineering networks.

However, if the well structure for sewage drains is removed too far from the house, then the pipeline between them will have to be installed every 10–15 meters, which will lead to additional considerable expenses. But this will have to be done, otherwise if the pipe is clogged, you will have to open up the soil in order to simply clean it.
