laying sewer principles in a private house

laying sewer principles in a private house

Sewerage in a private home may not be performed correctly without pre-planned workload.

For every house needs a special project, since the use of a common sewer system on the device without taking into account the specifics of the private object is likely to lead to disastrous consequences.

Therefore, before making water drain in a private home, experts recommend to carefully read the how to make the project.

It does not make common mistakes that result in the unjustified rise in the cleaning system and its premature failure.

To start recommend reviewing the thematic video, that can be used to estimate the amount of work and coming to know the details of how to carry out the sewers in a private home.


In addition to the right to draft, you need to know of what is going sewerage scheme for the private home.

Typically, components of the system are:

  • outer portion, through which drains depart to the central drainage network, built with his own hands a septic tank or cesspool;
  • internal wiring, for the collection of waste from households devices;
  • endpoints.

also sewerage project for the arrangement of a private home may involve the connection of fecal pump, provided that forced evacuation drains.

In addition, the project for a detached house can be subject of a separate exhaust system and rainwater harvesting.


  • Device features sump
  • installation Features septic tank
  • device external sewage for private homes
  • Internal wiring of sewage for private homes
  • sewage runoff out
  • connect a private home to a central sewer

device features sump

If connected to a central drainage system is impossible, then the special choose not anything else.

have to do with their hands in a private area in the worst case - the drain hole, at best - a septic tank.

Construction pit as in the photo, it will be cheaper, but it will have to limit ourselves to a life of service convenience.


In accordance with standard requirements of SNIP, the drain hole can not be made closer to a private home than 5 meters from the walls of the capital structure, with an indented by a fence at least 2 m.

distance from the drain hole to drinking water wells. must be at least 30 m

Given the characteristics of the private area, because usually for sump looking for a place in the far corners, we can conclude - the distance from the drain to the house will reach 35-50 meters.

This sewer lining should not be carried out near a private house water system.The optimal distance between them is 3 meters.

Taking into account an average slope of sewage - 3 cm per meter of the pipe, it turns out that the height difference of the outer surface, between the point of discharge wastewater from the house and the point of entry of the pipe into the drain hole at a distance of 50 meters, is 15 cm

project.with such calculation must include a greater deepening of the pit or the rise of the internal plumbing fixtures.

scheme for calculating the volume of a drain hole is performed based on each tenant of a private house, so that the needs of one person shall be 0.5 m 3.

When permanent residence of an average family, it turns out that the use of technology assenizatorskaya services have once in 2-3 months.

If septic tank arrangement will be carried out, vykachku drains can be done once every 5-6 months.

Features installation of a septic tank

sewerage project of a private house, which includes a septic tank, it is considered more convenient.Installation of a septic tank and its improvement, judging by the photos, did not require a lot of space, but will cost more.

purified liquid will be delivered to the site and can be used to feed the flower beds.

settled muck is selected from the septic tank about once a year, it can also be used for commercial purposes, as a fertilizer for the garden.

Driving septic tank

planning watering remediated water beds, it is recommended to make their own hands a separate tank for the accumulation of waste chemicals (after washing, washing dishes), and naturally occurring runoff.

Installing a septic tank goes to a depth of 1.5 meters, the distance from a private home can be about 5 m.

Studna reservoir under the recommended pit with his hands to arrange concrete or brick walls, as in the photo that will eliminate septic deformation under pressure of the soil.
septic tank installation depth allows us to calculate correctly, what the depth needed for laying sewer.

The specialists do not recommend connecting the pipe with his hands between the house and the septic tank with turns or bends.Best of all, if the stock is a straight line.

depth laying sewer pipe can not be less than 70-80 cm. Just specify this parameter for different regions can be, given the level of soil freezing.

In this case, the laying of pipes occurs slightly above the middle of its freezing.

And it provided that the surface of the land plot is not lies, from which in winter will need to constantly clean off the snow drifts.

device external sewage for private homes

drafted outdoor sewerage, it is recommended to take into account three important factors:

  • freezing soil depth;
  • soil characteristics;
  • possibility of mechanical pressure on the soil.

Outdoor water drain in a private home must be done below the level of soil freezing.

If the depth is calculated incorrectly, the temperature is lowered to the street, the liquid in the pipes will freeze, which will lead to their depressurization.

In the place where you connect an external sewer system with a drain pit or septic tank, the depth of laying should be at least 100 cm.

great importance to the effective operation of the drain pipe gasket plays with the correct slope.Usually do

bias external sewage is recommended with the index of 2-3 cm per meter of pipe.

sewerage project for a detached house with similar parameters is key to the proper functioning of the system.


In this case, the run-off from hard components will pass through the line of 70-100 cm 3 per second.Thus

solid components will remain suspended and will not form a precipitate on the inner walls.This means that eliminates blockages.

fulfill the technical parameters of products with a greater role in settling sewage hands.Make a connection to the private sewer drain, you can use several types of pipes.

From the correctness of their choice will depend on the life of the entire system.

Cast iron items - mostly used for arranging industrial runoff waters aggressive nature.

Due to the high cost of this type is not used in private construction, but if such a home sewage serve about 100 years.

steel products in the private sewer rare, but still used.Their use is justified for outdoor sewerage, which will be located in the ground under the load.

While doing with their participation outdoor sink is still not recommended, as the other became more susceptible to corrosion.

Plastic - a universal form of products, their application can be made with your own hands both external and internal private sewer system.

Internal sewerage layout private home

scheme on which it is planned internal wiring sewage in the residential areas of a house can have different levels of complexity.

According to experts, most of time it takes to connect with their own hands pipes and fittings inside the house.Therefore, to speed up the process, you must first prepare a draft.

sewerage scheme in the house

To learn how to do it right, it is better to see a thematic photo and video material with the participation of experienced craftsmen, who have decided to share their knowledge.

Mounting sewage in a private home is performed using plastic pipes, which are easily identified by the color gray.

Internal wiring diagram provides a connection to the drain, in addition to the bathrooms, and various household appliances.

To connect toilet use products with a diameter of 110 mm to other devices (bathroom, sink, sink, etc.) - 50 mm.

If you do not plan to waste large, the riser can be made of 110 mm pipe.The slope to the standpipe for 50 mm pipes made of 3 °, to 110 mm - 2 °.

Sometimes the internal drainage system of a private house is done by hiding under a layer of concrete pipe solution.

In this case, it is not a good idea, since the sudden depressurization of the system repairs require the destruction of the surface treatment of floors or walls.

ideal solution for inner liner sewage in a private home can be considered a wiring formed at the level of the ceiling of the basement space, a ground floor house.


Moreover, all visible parts of the system can be hidden in the aesthetic attractive boxes, which can be made with their own hands Plasterboard.

If drainage is still hiding under the concrete layer, it is necessary to determine the correct slope of the pipeline.

Furthermore, before filling the pipes with a solution, it is recommended to use clamps to ensure their sustainability.

It is very difficult to predict how they may be displaced during concreting.

This saddle mount should not be placed very close to the edges of the pipes due to thermal deformation.

When hot water flows for sewage plastic products, they tend to lengthen, but under a layer of concrete to do them it will be nowhere.

While the thermal conductivity of concrete will allow, the pipe will give him the temperature, but as soon as that is not enough, the pipe may burst.

If the planned pipeline laying in the wall of a private house with the subsequent plastering the surface, the product is recommended to isolate some soft material, usually corrugated cardboard, glass fiber or mineral fiber.

add the topic resettlement internal wiring in a private home sewage systems enable the following video.


sewage runoff out

Avoid connecting mismatch inner and outer tubes of a private house sewage system is possible if the construction work to begin with effluent release point.

Edition - part of the system, forming a connection pipe directed to a septic tank with a central riser.

When constructing sewerage issue of a private house, you need to do two important things.The first - to organize the release angle without a sharp transition.

usually in place of release waste water changes direction at a right angle.More often than not, connect the outer pipe and the riser with two taps for 1350.

What can extend the life of the pipeline, reduce noise, eliminate the formation of blockages and ensure full outflow of used water.

The second point that needs to be taken into account - is laying the pipe through the wall.For her, doing a technological hole at a certain height.

As a rule, if the planning of sewerage and water supply was made during the construction of private houses, such openings are performed in advance in the process of masonry walls or foundation unit.

a steel sleeve with a diameter of 20-30 mm, the diameter must be greater than the diameter of the sewer exit, it lay in the doorway to the solution.


After laying the pipes, the clearance between the sleeve and the pipe wall is compacted insulating material with insulating and water-repellent properties.

Its presence is necessary in the case of new private homes shrinkage to prevent the pipe from deformation - contraction and subsequent fracture.

The liner is better to take such length that its edges were on both sides of the foundation and walls of 1.5 cm.

connect a private home to a central sewer

to connect sewage private house to the central sewerage, you must obtain permissionan enterprise that is engaged in service of acceptance of wastewater.

also need to agree on a project laying sewer with neighbors and the organization responsible for road use.Typically, the pipeline lay under the ground to a depth of one meter.

If private house located below the location of the central sewage system, it is necessary to use the pressure of the complex.

Before starting work on the arrangement of a suction well, all planned actions agree with the neighbors.

The principle of operation of this system lies in the withdrawal of effluent into a separate tank, from where with the help of fecal sewage pump are fed to a central drain.

When connected to a receiving tank several private homes have the opportunity to save money and build a well combined forces.

After tapping into the public sewerage system to take care of the withdrawal of rainwater.When drainage capabilities make directly on a private site, after which the water is used for watering the garden and the garden.

If this is not possible, then the storm drains and discharged via a central sewer standpipe.


To do this, construct a separate receptacle, since the heavy rain water may leak out.

Box for rainwater also perform separately, explained this approach is low-bandwidth private pipeline compared to the general sewerage system.
