Every owner of a future private house dreams of comfortable conditions residence. Comfort is impossible without a quality sewerage system. If you decide to build it yourself, then before you dig a foundation pit, you need to clarify whether there is a central sewage system near the house. Subject to the location of the city sewer near a private house, there is a need to connect to the system.

If you look at the process of installing sewers in a private house or apartment with a non-professional eye, then you may not see a fundamental difference. Looking at the details, there are significant differences. The advantages of laying sewerage in a private house are obvious. In the bathroom of an apartment, you will not be able to arrange the plumbing equipment the way you want, and your sewage system is constantly dependent on the decency of your neighbors.

Connection to central sewerage private house

Connecting the sewerage of a private house to the city sewerage can be done independently, but for this you need to obtain the appropriate certificates and approvals. This is problematic, but will save a significant amount of your budget, which can be spent on other needs of a private home. You should not connect the sewerage illegally, because after that you will have to pay a large fine and spend a considerable amount on dismantling.

Stages of preparation:

• Construction of an inspection well on the territory of the site, with which you can control the system, as well as carry out maintenance and repair work.
• Digging a trench for the pipe and joining the central well.
• Compound internal system and pipeline devices.

Advantages of connecting to the central sewerage of a private house

• Significant savings on the purchase, installation and maintenance of an autonomous sewer system.
• Long term use of sewerage subject to regular payment.
• There is no need to control the quality and quantity of water.

preparation of trenches and laying pipes for connection to the central sewer

First steps

First you need to decide on the type of connection. Separate is used when connecting two types of sewerage - storm and domestic. With a mixed connection, one large pipe is carried out, which is connected to a common system. Tapping into the city sewer is impossible without visiting the city water utility, where you need to get permission to connect to the city sewer. If technical capabilities allow, you will easily be given the necessary document. Next, you need to call a specialist to draw up a plan and apply a laying diagram to it, you also need to conclude an agreement on drafting a project, which is approved by a representative of the water utility, as well as an architect. Neighbors must sign for permission to work near their homes and plots. Finally, the water utility signs a contract for the collection of sewage.

If the pipeline passes above the site, then there is a need to install a pressure sewer:

• According to the principle of a septic tank, a receiving well with a sump is equipped for Wastewater.
• A pressure water supply is brought to the manhole, from which wastewater will flow by gravity into the city network.

There are several ways to connect a branch to a sewer pipe:

1. Install the tee on the cut piece of pipe. They put it on with the help of a coupling, the joints are welded.
2. Connection via adapter adapter. But in this case, it is necessary to shut off the water in the system, make a hole with a drill, tighten the adapter, tighten the bolts. If there are no bolts, then nuts are tightened on a degreased surface.

Entrust this process to specialists, because the quality of the tie-in depends on the absence of leaks and the correct operation of the system.

When digging a trench, you need to choose the right width so that there is room for laying parts. Do not forget to tamp the bottom well and start preparing a pillow from a mixture of sand and gravel. It must be compacted at the beginning and two meters from the well. For an external pipeline in a private house, cast-iron or polymer pipes are used.

preparation of sewer pipes

Plumbing sequence:

1. Pipes have a socket down.
2. Joints are thoroughly cleaned.
3. Joint parts must be well lubricated with soap.
4. Measure the length and insert the pipe all the way into the socket.

According to this scheme, the entire pipeline is laid. Before backfilling, check the slope of the pipes. First, the pipe is covered with sand by 5-10 cm, then it is necessary to pour water on it so that the sand subsides, and then the soil is covered.

After you have resolved the issue with the central sewer, think about how to remove from the site rain water. This is a simple procedure, but please note that during heavy rain the receiving well will overflow, and sewage will pour out. In order to avoid trouble, it is necessary to make a tie-in separately, because the central pipeline is capable of more than a private sewer system. In the event of unpleasant surprises from the water utility, or other nuances in which it is impossible to connect to the city network, install a separate container on the site to collect rainwater. The reservoir is cooled by the soil. Due to the low temperature, algae and bacteria multiply in it. If you lay a drain to it and put a filter, then garbage will not get into the tank. Water from the tank can be used for watering the garden or other household (non-drinking) purposes.

connecting pipes to the central sewer

Pipeline testing stages:

1. There is a need to determine the correct laying of the system and the accuracy of the docking, so external lines must be laid without rubber rings.
2. The stage is carried out after the installation of the system, when the pipes and septic tanks are not yet covered. The system is subjected maximum load in all areas. At this stage, you can visually identify existing problems, see defects and damage.

For self-assembly sewer pipes the following mistakes should be avoided:

• Check pipe slope during design and assembly.
• Do not apply excessive force when spigot installation, this may damage the seal. Use Vaseline to lubricate to prevent breakage.
• If you have no experience with glued joints, then use a bell-shaped joint, because it is easier to assemble.
• Incorrect fastening of pipes leads to their sagging and destruction of rubber seals.

Connection problems

There is a possibility that from the sewer branch to the house there may be various engineering Communication, heating, electricity, gas. Connection not possible:

• if several communications pass between the house and the city sewer;
• when the system is dilapidated;
• when passing underground private system with high connection costs.

rules for connecting to the sewer

In such situations, it is possible to install an autonomous system for wastewater treatment. It is necessary to pump out water from septic tanks twice a year, waste sludge can be used as fertilizer. Unprecedented demand for modern autonomous sewerage due to several reasons-advantages:

• Due to the durable housing, the plastic is not deformed and does not undergo corrosive changes.
• The unit is compact and easy to assemble, has a light weight, takes up little space on the site.
• Special maintenance is not required, there is no need for the services of vacuum trucks, used sludge does not have an unpleasant odor.
• Long service life - 50 years.

The only drawback of autonomous sewer stations- dependence on electricity, i.e. the installation is not recommended for use in an area where there are power outages. Before installing a septic tank, you need to decide how many family members will live in the house, and calculate how many liters of water to purchase a sewer system.

Regardless of what choice you have made - you have preferred city sewerage or decided on an autonomous one, remember that it is better to entrust installation and connection to professionals. Thus, you will relieve yourself of unnecessary responsibility and avoid high financial costs for expensive repairs. Specialists themselves will determine the place of installation of a septic tank or laying a trench to the city sewer. In addition, they can help you design necessary documents. You will receive a quality service, and you will also be able to enjoy the benefits of civilization for a long time.

Of course, in modern dwelling without a well-equipped sewer system today is nowhere. And in any case, it will not be superfluous to find out at least in in general terms: sewerage connection diagrams - what they can be. After all, it is one thing to trust the will of plumbers and quite another to be able to fix everything on your own if something happens.

What general principles should be followed

Despite the fact that there are a lot of schemes for arranging the sewer system, there are some general principles that can be guided.

Sewerage - component water supply and drainage systems designed to remove solid and liquid waste products

As a rule, in a private house, the sewerage system consists of:

• Central riser;
• smaller diameter: all wastewater enters the riser through them;
• Horizontally located pipes of a larger diameter: through them, water flows directly into the sewer, treatment facilities, etc .;
• Elements plumbing equipment: sink, toilet, bidet, etc.

Traditionally, the kitchen and bathrooms are located in close proximity to each other. This is done in order to minimize the number of joints, pipes to the maximum possible minimum, in order to facilitate the withdrawal of waste water into the system. After all, it is the bathroom and kitchen that account for up to 90 percent of all wastewater.

If we are talking about a multi-storey building, it makes sense to arrange bathrooms, toilets and kitchens under each other. In this case, it will be possible to place all plumbing fixtures simply on top of each other, thereby simplifying the sewer construction scheme as much as possible.

Important! If the house has a complex system plumbing fixtures, and a large number of all kinds of branches, then you should think about installing a special sewer pump. This pump may also be required if, for example, it is not possible to provide the sewer pipes with the necessary natural slope.

What you need to consider when drawing up a sewerage connection diagram

In fact, there can be quite a few factors that can affect the drawing up of a sewer connection scheme.

Sewerage - complex engineering structures and sanitary measures that ensure the collection and disposal of polluted waters outside populated areas, as well as their purification and neutralization before disposal.

But in any case, you will have to take into account the following:

• Landscaping features of the site on which the sewer is being equipped. At the same time, it is important that the natural slope of the pipes is ensured. Cesspool should be at the lowest point of the system. Then the wastewater will be able to flow down by gravity - under the influence of gravity;
• Soil type: sandy, clay, etc. This will determine how deep the sewer pipes will have to be placed, how laborious the process of digging the trench will be, and whether it will be necessary to further strengthen the soil;
• Depth of soil freezing. This parameter will affect the nature of the organization of the insulation of the sewer system, the choice of pipe materials, etc.

Of course, other individual characteristics this particular area.

Which pipe material to choose

If in former times the craftsmen were not spoiled by the abundance of all kinds of materials from which sewer pipes could be purchased, now the picture is just the opposite. However, it is the huge wealth of choice that determines its complexity. However, we can safely recommend or polyvinyl chloride. Pipes made from these materials are distinguished by both low weight and resistance to corrosion. In addition, such pipes are easy to install: they do not require the use of welding machine. In principle, even the most novice master can quite easily cope with their installation.

PVC pipes are polyvinyl chloride products designed for the installation of pipelines for various purposes.

Do not be afraid that during the operation of PVC pipes they will begin to emit aggressive chemical substances A: They are completely non-toxic.

However, in addition to pipes, additional devices may be needed in the form of fittings, sewer hatches, connecting rings, adapters, etc. The joints of all these devices will need to be treated with a special sealant.

When choosing the diameter of pipes for sewerage, several factors must be guided. For example, this is the number of plumbing points connected to the sewer. The more of them - so, accordingly, it will be necessary to choose pipes of a larger diameter. Otherwise, the whole system will simply “choke”, unable to cope with the volume of water.

But anyway, the diameter of the pipe passing from plumbing device, must be either greater than or equal to the diameter of its drain pipe. The diameter of the pipe for the riser must be at least 10 centimeters. If you do not plan to connect a toilet bowl to it, then you can limit yourself to a diameter of 5 centimeters.

The more plumbing points in the building, the thicker the drain pipes should be.

At the same time, the following rule must be observed: the length of the pipe leading from the plumbing equipment to the riser should not be more than 3 meters. As for the toilet, this distance is reduced to one meter. If it is absolutely necessary to increase this distance, then you will have to take pipes with a larger diameter.

The Importance of Preplanning

Before proceeding directly to the installation of the sewer, you need to draw up on paper a preliminary detailed diagram of it. In this case, it is necessary to indicate which pipes of what material, what length and what diameter will be needed in a particular section of the system. All necessary additional devices in the form of splitters, adapters, etc. are also indicated. In the future, this will avoid many unforeseen difficulties during the installation work.

As practice shows, in the vast majority of cases, all plumbing fixtures are brought to one central riser. But, if there are many such devices, or they are spaced apart different rooms, which are far apart from each other, then more such risers will be required.

A properly drawn up sewerage plan will allow you to qualitatively recreate the system, taking into account all the necessary factors.

If the sewer is equipped in a private house, then the scheme should also be included in the plan external sewerage. Indeed, in addition to the elements internal sewerage, it will also be necessary to provide for the arrangement drain pit, trenches, manholes, etc.

Sewerage connection according to the scheme

As soon as the project is ready, you can proceed directly to the installation work at the facility. Typical scheme for a private house, this will include:

1. sewer riser;
2. Toilet, washbasin or sink, as well as a bathroom;
3. Siphons for all these plumbing fixtures;
4. Flush tank for the toilet;
5. Attaching couplings to the wall;
6. Connecting pipes running at some slope to the riser.

Of course, if necessary, this scheme can be changed at your discretion, but the typical picture looks like this.

A siphon is an element of plumbing. It is a pipe bent in several places, through which water is drained into the sewer system.

The sewer riser is connected to the pipes using horizontal pipes of the same or even larger diameter than the riser. Pipes can be placed in the basement, in the basement or under the floor. It is also necessary to provide for the presence of revision wells, which are required at the places where the pipes turn.

All pipes of the system must be connected into one single pipe. large diameter, which, in turn, is removed from the house and docks with the external sewer system. Sewer pipes are attached to the walls with special clamps.

Options for tapping the sewer system of the house into the central system

If there is already a centralized sewer system outside the house, then there are several options for how you can join it:

• Insertion with a tee;
• Insertion with adapter.

In the first case, you will need to cut a piece of the main pipe and build a tee into it. The tee itself is fixed on the pipe with the help of a coupling, then all joints are welded.
More modern version can be considered a special adapter. It also crashes into the main pipe.

A pipe tee is a piece with three gaps that connects the components of the pipeline and is installed at the points of its branching.

In any case, it will be necessary to block the central sewerage and, of course, obtain permission to carry out mortise work. Otherwise, you can not avoid a rather large fine. The law even provides for imprisonment in case of unauthorized connection to the central sewer.

What the experts say

Vladimir, service company employee: Many people forget to get written permission from their neighbors before starting work. In the future, this can turn into many difficulties and conflicts. So in any case, it is better to take care of their consent to sewerage in advance. As for the magnitude of the slope of the pipe, the rule works here: for each meter of the pipe, the change in height should be from 2 to 15 centimeters.

Anton: All elements of sanitary equipment must be equipped with S-shaped or U-siphons, which would provide a natural water seal for unpleasant odors that could get inside the house from the sewer.

Outcome

In principle, laying sewerage on your own is not so difficult task. It is facilitated by the fact that in the overwhelming majority of cases one can be guided by standard schemes to connect. But, faced with unforeseen difficulties, do not be shy to ask for help from qualified craftsmen.

In the process of building a private house, its owner has to deal with the design and subsequent installation of communications. The absence of centralized communication networks in the construction area leaves the developer no choice - he will have to install an autonomous sewer. For those who build housing near centralized networks, there is a choice - to equip an autonomous system or connect to the city sewer. As practice shows, most often choose the second option. Let's understand the advantages and nuances self connection private building to centralized system.

Why is this option beneficial?

When deciding to crash into a centralized sewer, the developer receives certain advantages:

• The opportunity to significantly save on the purchase, installation and maintenance of an autonomous sewage system.
• The completed connection allows you to use the sewer line for a long time. The only condition is that the necessary payments are made on time.
• No need to control the quantity and quality of wastewater.

All this makes the tie-in into the centralized sewer system extremely attractive to most developers.

Connecting a private house to a centralized sewer system- convenient and practical solution drainage problems

What is the right place to start?

First of all, you need to decide on the type of sewerage passing near the house. Depending on this, two possible types of connection are distinguished:

• Separate. It is used in case of connection of storm and household sewerage of a private house. It is carried out separately in two systems.
• Mixed. Can be used with piping mixed type. In this case, one common pipe, which crashes into the system.

It must be understood that the sewer input, which will connect the intra-house system with the centralized one, is financed by the developer. This can add up to a hefty sum. Those who want to save money can try to implement the planned event during the planned modernization of the centralized branch. To do this, before starting work, contact the water utility, where you can offer your financial participation in carrying out such modernization. With a positive decision, the organization will take over part of the work, including design and connection, which will provide significant savings. Another way to pay less is a collective tie-in with neighbors. In this case, the costs can also be reduced.

Self-tie-in to the central sewer is a troublesome undertaking. Those who do not like to run around the authorities can be recommended to contact a company that provides such services. In this case, the developer will be relieved of the need to collect the package permits and solutions organizational issues. In addition, the procedure for commissioning a new branch is greatly simplified. However, such services are not cheap and those who want to save on them are likely to refuse.

Those who decide to deal with the issue on their own will need to collect the following documents:

• The plan of the site and the house, on which the scheme of laying the sewer pipeline should be applied. Performed by a company specializing in geodetic expertise.
• Specifications for the new connection. Developed by an organization that is engaged in the maintenance of sewer communications.
• The project of connecting a branch to a centralized sewerage system. The document is prepared by a specialist designer. The basis for it is the previously obtained situational plan and technical conditions.
• Coordination of the prepared project in the water utility and the Architectural Department. In parallel, a company is being approved, which will subsequently connect a new branch.

Another important nuance. It is worth obtaining the consent of the residents of neighboring houses for the implementation construction works in close proximity to their sites. A document should be prepared and signatures of neighbors should be collected. If the pipeline will pass through sections where the networks of other organizations are located, for example, electrical or thermal, and it is also supposed to be carried out under the roadway, additional permits will be required. If all these procedures seem too troublesome and there is a desire to carry out an unauthorized tie-in without collecting documents, you need to know that such actions provide for an impressive fine and forced dismantling of the pipeline at the expense of the developer.

To equip the external branch of the sewer, which will be extended to the central highway, you should use a special pipe

How to equip the site before the tie-in?

The current SNiPs clarify that permission to lay a pipeline to the central highway can only be obtained if there is an overflow sewer well nearby. A branch from the house should pass through it. In this case, it must be borne in mind that the pipe leaving the private household must enter the well at a certain angle above the drain level. In addition, the pipe is laid to a certain depth. Its value depends on the level of soil freezing.

To determine the laying depth, you can use the values ​​\u200b\u200bgiven in SNiP P-G.3-62, which vary depending on the building area:

• For the northern part of Russia, they are about 3-3.5 m.
• For middle lane our country - 2.5-3m.
• For the southern regions -1.25-1.5.

These values ​​are quite approximate. Everything is very individual and depends on the type of soil, terrain and nature. ground water. In general, the average laying depth is 1-1.2 m, while the minimum value is 0.5 m, measured from the top edge of the pipe. When digging a trench, keep in mind that its depth should be 5 cm more than the intended laying depth. Another important point- slope of the pipe. With a slight slope, the wastewater will leave extremely slowly, which is fraught with clogging of the pipe. If, on the contrary, the slope is too great, the water will leave too quickly, not having time to wash off grease and other contaminants. It also causes blockages.

When installing a sewer branch before inserting into the central system, the required slope is observed. A revision well is installed above the sharp turns of the pipe

In order not to face such troubles, sewer pipes are 1-2 cm per linear meter. Another important point is the presence of turns on the track. Ideally, they shouldn't be. If this is not possible, you should definitely avoid sharp turns, “smoothing” them as much as possible. If it is necessary to turn the line by 90 ° or more, it will be necessary to equip an inspection well at the turning point. Also, experts recommend installing an additional one in case of a large length of the sewer branch. It will allow you to control the system.

The next step is trench digging. It is important to choose a width sufficient for stacking the parts. In doing so, it must be taken into account that outer pipe should be characterized by a larger diameter than the inner. Most often it varies from 150 mm to 250 mm. In the case of a collective tie-in, a pipe with a diameter of 250 mm is taken; a 150 mm part is used to equip the branches to the yards. It should be borne in mind that in this case, an additional revision well should be equipped at the input site of each yard. When choosing the width of the trench, you need to focus on the following indicators: for a part with a diameter of 110 mm, the width of the pit should be at least 60 cm.

The bottom of the trench is rammed and sand or gravel pad on which a sewer pipe is laid

The bottom of the excavated trench is leveled and well rammed. Then you can start preparing the pillow. It consists of gravel or sand, the layer of which is about 10-15 cm. It is not necessary to compact the pillow throughout, but it is necessary to do this from the side of the incoming pipe and two meters before the well. Under the sockets of the sewer pipes, it is necessary to make pits. Now you can lay the pipeline. Operations are performed in the following sequence:

• Pipes are laid in a trench from a slope with a socket down.
• The smooth edge of one part and the bell of the second are cleaned of dirt.
• The ring in the socket and the smooth edge are lubricated with a special lubricant. It can be a silicone compound or regular liquid soap.
• The length to which the part should be inserted into the socket is measured, and a risk is applied.
• The pipe is inserted into the socket until it stops.

Thus, the entire pipeline is laid. After its installation, the slope angle must be checked, only after that they start backfilling. They start with a layer of sand, which should cover the details to a height of about 5-10 cm. Then everything is very abundantly spilled with water. This is necessary so that the sand sags well. The settled material will reliably protect the pipeline from subsiding soil and stones, preventing them from damaging the pipes. This will significantly extend the life of the sewer branch. Now you can fill the soil.

According to the requirements of SNiPs, a pipe leaving a private building must enter the differential well at a certain angle above the drain level

Actually preparatory work finished on this. The only thing left to do is to connect new branch to the central sewer. This procedure can be performed only by employees of a specialized company, which was agreed in advance when approving the project. After the connection is made, it is necessary to notify the water utility about the readiness to launch a new line. The service company accepts the completed project for operation, and in addition concludes an agreement with the owner of the house on the reception of wastewater.

Solving the problem of storm sewers

- a mandatory stage of site planning. Output connection storm sewer to the household collector will not be able to solve the problem of storm drains. Such a "solution" significantly increases the load on the network, which can provoke even more big problems. There are two arrangement options:

• Installation drainage system private household with storm drains in a specially designed tank. A container for collecting melt and rain water is equipped on the site. It can later be used for watering the garden and other economic needs. It is optimal to mount a natural filter in front of the tank. They can serve as a small sump.
• Direction of wastewater to the storm sewer. It can only be carried out with permits. A pipe with storm drains is laid to the collector of a centralized system.

Connecting a private household to a centralized sewer can be done if desired different ways. But in any case, the participation of specialists is required. The only difference is at what stage they connect.

When arranging a sewer branch, revision wells are necessarily mounted, making it possible to control the system

Those who want to get by minimal cost, are engaged in the preparation of their own. The rest seek help from specialists who take care of all issues related to the organization and implementation of work.

Everyone dreams of having their own corner with all the conditions for a comfortable stay. An important of them is the connection to the central sewerage of a private house.

Most often, its independent installation is carried out by connecting to the central city network. To save time and cash for costs, you need to know all the nuances of the connection, legitimize this issue by coordinating it with the administration and obtaining permission. Illegal installation of communications connected with the city system entails the imposition of a fine and their dismantling.

Types of sewers

Connecting to the central sewerage of a private house requires knowledge and preparation from the organizer: it takes time to complete the documentation and financial investments.

To connect to the central sewer will require financial investments

There is the following classification of sewer water:

Types of sewer systems	Industrial - carry out laying at manufacturing enterprises		Stormwater - a system that provides the removal of precipitation and melt water from the terrain, bases and coatings	Household or household - a network that extends over vast territories covering settlement areas, it is designed to remove polluted water with human waste products
Wastewater disposal method	Gravity - water flows due to the slope of the pipes towards a specially installed container		Forced circulation - equipped with a pump that provides water flow
Placement of sewerage	Outdoor - placed outside buildings	Public - has a common well	Internal - located inside buildings
		Separate - precipitation is separated from domestic wastewater
		Mixed - the drain is carried out separately, but has a common well
Other systems for suburban areas	Cesspools and septic tanks		Filtration wells, in which the drainage of used water is directed to the ground	Sewer installations - modern systems in which the treatment of polluted water is carried out with the help of bacteria

To connect the central sewerage system in a private house, you must first complete the necessary documentation and obtain permission.

Before starting work, you need to take care of all the necessary documents

Used for cutting plastic pipes having a smaller diameter. Complexity preparatory phase depends on the condition of the city pipeline.

Disadvantages and advantages of connecting to a central network

The main disadvantage of this type of installation of communications for a building located outside the city is the duration of the procedure for agreeing and preparing documentation. Its duration is the same for both private cottages and for the construction of large structures.

The advantages include the following features:

• It costs less to connect to a public network than to install an individual cleaning station.
• Savings on the materials used.
• Simultaneous solution to the problem of drainage of rain and domestic water.

During operation, there is no need to clean and pump out water collection tanks, to engage in maintenance, this feature makes it possible to save on the process of using the pipeline.

The complexity of the terrain can affect the high cost of connecting to the sewerage of a private house: when the pipeline is located above the site. The solution is to install a pressurized communication system to the city network.

Where to start installation?

The primary issue is to find out the type of sewerage located near the house: separate or mixed.

It is necessary to analyze the costs and, if possible, minimize them. This is easy to do by connecting a common pipeline with neighbors.

The second way is to negotiate with local public utilities, offering funding for the modernization of the central drain. If the organization approves the proposal, then the task of designing and tie-in private pipe to the city sewerage will fall on the shoulders of the designers, thanks to this, the costs will noticeably decrease.

Holding self-assembly draining your home into the central sewer is a time-consuming and troublesome task.

To avoid collecting a package of documents, you must contact the organization providing the relevant services. But it is worth considering the cost of its work, which will increase costs.

List of documents

When deciding to make your own legal side question, you need to prepare the following papers:

• Site plan prepared by a surveying company, with a house marked on it and a scheme for laying pipes for sewer communications.
• Proof of ownership of the house and land.
• Documentation indicating technical requirements prepared by an organization specializing in sewer service.
• Plan of tie-in of a private pipeline to the central network, developed by a qualified designer.
• The plan consists of a longitudinal profile, a general plan and a master plan for networks.
• Permission for sewerage in a private house, agreed in accordance with the architectural design.
• Application to the executive company.

During last stage should collect the package necessary papers, you need to choose the company that will be entrusted assembly work sewers in a private house to city communications.

controversial points

Important for the construction work is the approval of the neighbors, as the installation will take place near their sites. To do this, you need to prepare a document with signatures of nearby living homeowners.

If the connection of the pipeline to the city sewerage system requires affecting sections of the electricity and heat pipelines, as well as roads, then additional permits are required.

Ignoring such legal aspects will result in the imposition of fines on the homeowner and the forced removal of installed pipes.

Quality control

For consent to conduct a sewer pipeline of a private house to central system drainage, some technical requirements must be met.

Insertion occurs only if there is a special plastic tank nearby, made in industrial conditions - a special well with a hydraulic drop of the required diameter and height.

It is not difficult to install home water supply, but the installation must be carried out taking into account the depth of freezing of the soil, be above the general communications, and also be carried out to the well at the required angle.

In the central part of Russia, the installation depth of pipes is about 2.5–3 meters, in the northern regions - 3.5 meters, and in the southern regions - 1.5 meters.

For each meter of pipe laid, a slope of at least 2 cm must be made, a similar requirement provides a self-cleaning speed for pipelines.

And a few more points:

• The drainage network does not provide for sharp turns, such a design can lead to clogging of pipes.
• The diameter of the pipeline should be between 15 and 25 cm.
• For tie-in, a socket connection and silicone grease are used.
• A sand cushion 10–15 cm thick is laid at the bottom of the trench; it must be rammed next to the well.
• Upon completion of the work, the slope of the pipe system is checked, then backfilled with sand and soil.
• After all these activities, a written agreement on sanitation is concluded between the water utility and the homeowner.

When connecting storm drains to the central sewer system, it is necessary to collect a package of documents and permitting approvals. If they could not be obtained, then it is mounted autonomous system collecting sediment water.

Possible problems

Difficulties in connection may arise due to the location of other communication networks at the sewerage site: a heat pipeline, an electrical network, a gas pipeline.

It is not possible to connect to the city network under the following circumstances:

• in the presence of several communication threads on the site;
• unsuitability public sewerage caused by her old age;
• high price for a tie-in private network located underground on the site.

In this case, the installation option remains. Septic tanks are an element of the waste and utility water treatment system. This kind drainage system has a number of advantages:

• the plastic used for them is not subject to corrosion and deformation;
• the term of use reaches 50 years;
• does not require special procedures during operation;
• The design is easy to install and requires little space.

The disadvantage of autonomous stations for the removal of waste water is the dependence on the power grid. Before installing a septic tank, you need to calculate its required volume, depending on the number of people living in the house.

Exploitation

Inserting the sewerage system of a private house into the central network does not protect the owners from possible problems during its operation. For correct operation systems without the hassle you need to follow the rules of operation:

• Prevent waste and household waste from entering the drain.
• Kitchen siphons installed in the sink should be flushed regularly, and the toilet should be cleaned with a plunger.
• A wire brush for plumbing fixtures removes blockages.
• Harsh cleaning products should not be used as they release toxins into the environment and negatively affect the human body.

It is best to entrust installation work to specialists, and not to insert into the central sewer yourself. This will avoid liability for possible mistakes and avoid repair costs.

Professional firms will develop the project and determine the optimal location of the septic tank, wells and trenches to the central sewer. Additionally, specialized organizations will take on the task of collecting approvals and documents.

By paying a certain amount for the services rendered, the owner will receive quality system spillway, will be able to fully enjoy comfortable rest outside the city.

The central sewerage system, connected to a private house, once and for all solves the issue of water disposal: removal of sewage and accumulating storm water. To connect, you will need to comply with some legal formalities related to paperwork. Therefore, before starting work, it is worth determining whether the connection to the central sewer riser necessary.

Tapping into the central sewer is justified for several reasons:

1. Savings on installation. There will be no need to install and maintain a septic tank, which requires significant material costs.
2. Ease of maintenance. To continue to use the services of public water disposal, it is enough to pay for the services provided in a timely manner. sewer well you need to regularly service: pump out accumulated effluents, monitor serviceability. You will need to regularly pay for the services of a sewer.
3. There is no need to control the amount of wastewater discharged into the sewer well.

If the benefits are significant enough then a tie-in to the central sewer is necessary. After deciding on the feasibility of connecting, determine what steps will need to be taken to connect to the riser legally.

Step by step paperwork

Connecting a private house to a central sewer is legally allowed, but requires strict adherence to the rules for paperwork. Follow the following order:

1. Contacting a geodetic company. At this stage, a scheme of possible connection is developed, taking into account the characteristics of the soil, the depth of groundwater, and the location of the sites. The service is paid.
2. Receipt specifications. Technical specifications are issued by an organization serving the existing water supply and wastewater disposal systems. The organization will consider the possibility of connection and issue permission for the tie-in. If the technical conditions do not allow connection, the organization provides detailed description reasons for refusal, which can be challenged in court.


3. Project. Connection to the sewerage is carried out according to the project made by the specialist. Documentation is prepared on the basis of previously issued technical specifications and a plan issued by a surveying company.
4. Coordination. All documents are checked again. If there are no errors in the project and specifications, permission is issued for the tie-in. The company specified during the agreement will connect the new network.

The difficulty of connecting in a private house often lies in the disagreement of neighbors to carry out construction work in close proximity to their sites. Even at the stage of paperwork, it is worth collecting the signatures of the residents that they do not mind the installation.

Installation work

Only representatives of a specialized installation organization. At the stage of contacting the company, an estimate will be drawn up and the cost of services rendered for connection will be calculated.

To reduce costs, you can only agree on a tie-in to the central sewer riser, and connect the private house and the wiring of the house line yourself. The laying of the pipeline must be completed before the arrival of the installation organization.

When laying the pipe from the house to the central riser, the following conditions are observed:

1. At the bottom of the trench is laid sand cushion. The bottom is well compacted with water flow.
2. The slope of the pipe is strictly observed, which is at least 1 cm per linear meter.
3. The socket is mounted from the slope downwards.
4. Ideally, there should be no turns in the pipeline, but if corners are necessary, an inspection well is installed above it.

It happens that neighbors or well-meaning friends recommend that the person who decides how to connect to the sewer do the cutting himself. But this is a gross violation of the existing building codes. The person who decides to connect in this way should be prepared for the consequences:

1. Penalties.
2. Disconnection from the sewer network for a long time.

Inspections of the water supply lines are carried out regularly, so there is a pipeline for a long time, independently embedded in the central network treatment facilities, will not be. The formalization of the tie-in requires material investments, but it will be cheaper than the fine that you have to pay.
