It is more convenient to lay trenches for sewage pipes at the same time as digging a pit. It is better when the underground laying of pipelines - www.drilling-spb.ru, is carried out with corrugated plastic pipes with an outer diameter of 110 mm.
When using them, you can do without additional fittings, and the absence of rubber seals makes the sealing of the pipeline more reliable.
Orange sewer pipes are intended for external use, they should be used to drain wastewater into a septic tank or other local treatment systems.
The cost of these pipes is higher than the cost of gray pipes, but it is not recommended to save on safety. Gray pipes lose their elasticity and strength in the cold.
Orange pipes are much more resistant to environmental influences, they better tolerate soil loads. Orange pipes are produced by both foreign and domestic manufacturers.
In order for the wastewater to move by gravity, the pipes should be placed at a minimum slope of 1–3 ° from their length.
For example, if the length of the pipeline is 5 m, then the minimum level difference between the two ends of the pipe will be 5 ° (0.01 or 0.03%), which becomes clear from the following calculation: 0.05-0.15 m \u003d 5- 15 cm.
Often, the average slope of the sewer pipe is set equal to about 2 cm for each running meter pipeline. It is not recommended to make the slope more: liquid drains will drain through it into the septic tank faster.
Runoffs with greater density will settle on the pipe walls, which can ultimately lead to blockage.
The diameter of the pipe must be selected in accordance with GOST, taking into account the volume of wastewater. The main thing is that the inner diameter of the gravity sewer pipes connected to the septic tank is at least 100 mm with a wall thickness of 2.8 mm or more.
This diameter will avoid blockages in the pipes. Pipes of the same diameter should be used when underground pipelines are laid from a septic tank to a subsequent wastewater treatment system.
External sewage pipes must be laid with a slight slope so that domestic wastewater flows by gravity into the containers of a homemade septic tank.
If there is an opportunity for equipment to enter the area for digging trenches for sewer pipes, it is more rational to rent a trencher with a chain width of 150-200 mm.
Using this technique, you can lay 1 meter of trench in just a few minutes.
When laying a shallow trench, sewer pipes laid above the freezing level of the soil must be additionally insulated.
The soil in the trenches for the pipeline must be sufficiently dense. Therefore, after laying the trench from the house to the septic tank, the soil under the pipe must be carefully tamped and compacted. Weak or loose soil can sink unevenly.
Then there will be a possibility of failure or subsidence of part of the pipeline, which can lead to a change in slope and damage to the pipe.
In addition, you should not bury the pipes with loose soil, which can also cause uneven subsidence of the soil with the corresponding consequences in the form of violations of the slope and sealing of the pipeline.
Such an outcome is especially likely if pipe joints fall on the subsidence zone. It is better to bury the pipes with sand from below and from the sides, having previously tamped the soil into the trench.
The joints of plastic sewer pipes must be sealed with concrete and silicone sealant.
Often, a volatile septic tank is mounted on the site, in which an aerobic environment is created with the help of a compressor. In this case, experts recommend routing the compressor hose into the inlet pipe trench.

Laying of external sewerage, in the country
Outdoor sewerage in the country - this is a part of the pipeline system located outside the house, designed to divert waste water from buildings to a treatment system or to a centralized sewage system.
!} The laying of pipes for external sewerage in the country is carried out underground, usually at a depth of 0.6 to 1 meter. Underground pipelines are laid with a slight slope towards the sewer receiver from 3 to 1 cm per linear meter. meter, depending on the length.
For laying underground sewage pipelines, only thick-walled pipes with high ring stiffness are used. Namely, PVC pipes with a wall thickness of at least 3.6 mm, brown or red, in some cases, when laying sewers at great depths, corrugated pipes withstanding a higher load can be used.
Attention! For underground installation, only thick-walled PVC pipes with a wall thickness of at least 3.6 mm or even more reinforced corrugated pipes can be used. PVC pipes for underground installation are usually available in brown or red color.

Laying pipes for underground sewage in the country in most cases it is done manually, without the use of any construction equipment. This is often very important in the country, especially in those cases when there are already plantings or a lawn on the site, because when laying sewer pipelines manually, minimal damage to the ground cover occurs.
The process of laying an underground sewage pipeline is as follows:
First of all, a trench of the required length and depth is developed on the base of which the sand is filled up and leveled under the required slope, thereby creating a solid and even base for the subsequent laying of the sewer pipeline. Further, through rubber seals, sewer pipes are connected and laid on the prepared base.
External sewerage pipe laying includes the connection of the sewer pipeline to the sewer receiver. This connection must be absolutely tight, otherwise there is a high probability of flooding the sewer sink with groundwater.

Wastewater treatment plants of deep biological treatment of "Topas" type and other polypropylene containers are connected to the supply pipelines by means of a socket joint, the connecting socket is welded with a special welding gun into the sidewall of the container being installed.
The connection of the pipeline with the sewage receiver made of fiberglass is also completely tight - the connecting pipe is inserted in the factory.
The socket-pipe connections themselves are made through special rubber seals. They ensure complete tightness of the pipeline sewer system.
Our company "Comfortable dacha" carries out installation of outdoor sewerage in the country in various designs, adhering to one very important principle - we ensure the complete tightness of the entire sewerage system.
Underground sewerage in the country is produced, depending on various conditions, at a depth of 0.6 to 1.5 meters on a flat, previously prepared surface. Namely on a rammed, spilled water sand pillow... Backfilling of the trench is carried out only after checking the required slope of the pipeline being laid.
When installing a long-distance sewage system revision and, if necessary, rotary and distribution wells are installed.

Internal sewerage device - this is a wiring of sewer pipelines around the house with the output of taps to the necessary plumbing fixtures. The main function of the internal internal sewage system is to collect waste water from various plumbing fixtures and drain it into the main riser for subsequent movement through the external sewage pipeline to the sewage receiver.
Laying of all pipes for internal sewerage is carried out under a slight slope (from 1 to 3 cm per 1 m. linear) towards the main riser.
Internal sewerage device in the country it can be performed both in an open and hidden way. When laying in a buried way, pipes are laid in places unknown to the eye, between floors, under the floor, in the wall cladding.
For the laying of internal sewerage, thin-walled pipes of domestic production are used, as a rule, they gray... Depending on the configuration of the system, pipes vary in diameter from 30 to 110 mm.

Aboveground and underground sewerage from "Flotenk"
One of the main specializations of the company "Flotenk" is the development of sewer systems, usually consisting of aboveground and underground parts. By contacting this company, you can either buy ready-made standard systems that have proven themselves in practice, or order specialized ones that most fully meet the specifics and needs of each specific client. The company "Flotenk" manufactures almost all elements of these engineering complexes on its own production base from such modern material as fiberglass.
Sewer topology
Almost any modern sewer system consists of those sections that are located above the ground and those that are laid directly in the ground or in cavities specially prepared for this purpose. In addition, it includes underground sewerage tanks, which are designed to accumulate effluents and clean them from impurities in accordance with the accepted sanitary and hygienic standards.
As a rule, overground sewerage represents that part of the general system that is located in buildings and structures, as well as in close proximity to the surface of the earth (for example, most of the "stormwater" communications). Underground sewerage is characterized by the fact that it is buried in the soil, and therefore all its elements are hidden from view. These include pipelines and specialized tanks.
Underground sewerage
The design and installation of underground sewerage systems, as a rule, is a more technically complex, time-consuming and expensive procedure. It requires mandatory consideration of such factors as the estimated volume of wastewater disposal per unit of time, geography of the area, and climatic conditions. According to the current rules and regulations, underground sewerage installation should be carried out below the depth of soil freezing in winter. Almost all modern equipmentused for wastewater treatment and included in sewerage systems is intended specifically for underground installation.
Overhead sewerage
This part of the sewer system requires careful calculation and design, since it is it that is designed to collect all wastewater that must be treated and further discharged into the environment. Overhead sewerage installation is a rather difficult task, the solution of which should be dealt with only by true professionals in their field. For the manufacture of its components, materials such as plastic and fiberglass are now often used, which are distinguished by their strength, resistance to various kinds of mechanical and chemical influences, as well as a relatively low price.
Many people ask themselves the question: is it possible to lay sewer pipes on the ground? The answer is yes you can.
Before starting work, you only need to select the desired type of pipes. Previously, only asbestos or cast iron were used, now plastic ones are increasingly used.
They have many advantages:
- cost relatively little;
- during installation, you can make much fewer joints on one line;
- resistant to temperatures ranging from -50 to +60 degrees Celsius;
- they are joined by gluing or cold welding;
- have a service life of more than fifty years;
- resistant to liquids with an acidity index of more than 10 pH;
- lay plastic pipes can be done independently even in difficult areas, for example, under an asphalt surface.
To lay underground underground sewers, orange or brown PVC pipes are required. There are two types - SN4 (3.0 mm wall) and SN8 (3.2 mm wall).
If a transport will ride over the surface of the pipes, then products of the SN8 type must be used, the depth of laying in this case does not matter.
Each product has markings, so choose carefully. Incorrectly laid pipes will lead to an early malfunction.
Such pipes perfectly keep the aggressive action of the environment, they are smooth from the inside - which does not allow blockages to appear, and have a long service life. However, they are difficult to tolerate exposure to high temperatures. If in sewerage system liquids hotter than +40 degrees will merge, then the service life will significantly decrease.
An important point! Gray PVC pipes are often used for laying sewage inside buildings. They should not be used for outdoor work. They are too soft and will not be able to withstand significant stress from the outside. Their walls are only 2.7 mm thick.
Now on sale there are corrugated polypropylene products for sewage. These products are often used in industrial enterprises. They tolerate high temperatures well and are significantly stronger than conventional smooth pipes.
Even if you lay polypropylene corrugated pipes deeper than 2 m, the weight of the earth will not harm the product.
These products are perfect for laying underground sewers. Polyethylene is a fairly strong material, and the corrugated structure increases the strength against external influences several times.
An important point! It is allowed to bury corrugated pipes made of polyethylene 15 m into the ground without fear of being crushed. They perfectly tolerate temperature changes (unlike orange PVC products, they do not deteriorate from hot liquids) and aggressive environmental influences.
In addition, these products have excellent throughput... They have corrugated only the outer surface. The inside of the product is smooth, which prevents blockages from appearing.
There are also more rarely used materials. For example, asbestos-cement pipes. They weigh less than cast iron, can withstand heavy loads and tolerate aggressive environments well. But they are quite fragile, and their installation is much more difficult than the installation of polymer products.
PVC pipes cost less than other types. They are quite sturdy and have a long service life. But they don't hold up well high temperature, they will quickly deteriorate from a large amount of hot water. PVC pipes ideal for small private houses and summer cottages.
Corrugated polyethylene pipes cost more, but they are durable and reliable. Sewerage, will last for several decades without any blockages.
Diameter
Determining the diameter for sewer pipe, the outer and inner diameters must be taken into account, because the wall thicknesses can vary significantly.
For household street sewage, standard 110 mm are acceptable. This size is enough to serve a small a private house... When united sewer network several houses or a whole settlement are combined, the diameter must increase according to the calculations for the project.
The main mistakes when laying a water supply system under the ground
The unstable functioning of the water supply system can be caused not only by the wrong choice of the type of material used. Mistakes made during installation and installation can also adversely affect the functioning of the system. One of the most popular mistakes is trying to save money on thermal insulation. Frozen water in the system threatens not only the cessation of water supply or water drainage at home, but also the destruction of the pipes themselves. If during the cold season the water froze in the pipes naturally, then it will melt only in late spring - early summer. Finding an area with frozen water and eliminating the cause of the blockage will also be very difficult.
Helpful advice! You can insulate the water supply by laying a heating cable. This is far from the most budgetary option, since you will need to buy a transformer and a lot of electricity will be consumed, but this option is the most efficient. Heating cable will not allow water to freeze even in the coldest periods.
Insulating materials can be used to further protect the pipes and heating cable. The Energoflex insulation (13 mm is quite enough), fiberglass or foam is a good fit.
Many problems can lead to non-compliance with the plan suburban area at the beginning of the work on laying the pipeline. It is imperative to take into account the possible location of the already laid communications in order to avoid problems that arise if you touch or damage them.
