How to make a sewer in a private house

During the construction of housing often have to deal with issues of sewage. If you want to save money, you can start the installation work yourself, besides, they are not very difficult. The main factor in the private sewage system is the lack or availability of access to the central highway. If it (trunk) is located near your home, installation work will not cause labor. In this article we will talk about how to properly make a sewage system in a private house, we will show diagrams, photos and video instructions.

Device

The maximum amount of work you have to do when building an outdoor sewer. First of all, it is necessary to dig out several trenches and lay pipes to a depth of 50-150 cm. That is, the depth of laying should be below the level of soil freezing in winter.

If there is no central sewage system near your house, you will need to make an autonomous structure, which can be in the form of a cesspool, septic tank, filter well or local cleaning station.

Autonomous sewage

The cesspit has been used for a long time and it is easiest to build it yourself. For the interior walls should be used red ceramic brick.

Alternatively, you can build a pit of reinforced concrete rings, but you must first fill the bottom with concrete solution and cover the top of the pit with a hole for ventilation and a viewing window.

Septic is often used in homes intended for permanent residence. This design is very reliable and easy to install, that is, subject to the attached instructions, you easily install it with your own hands. Polypropylene septic tanks do not require frequent cleaning, which significantly saves money on the services of a vacuum truck. Thanks to the latest technologies, domestic waters undergo repeated purification when released into the device.

Preliminary preparation

Before you begin construction work, you must perform several sequential actions:

•  decide on the location of the waste well: it must be below the level of housing;
•  mark the place of the sewer pipe out of the house;
•  pay attention to the place of withdrawal of the collector pipe, since it is there that all wastewater from the dwelling will be concentrated. No defects, irregularities or distortions are allowed;
•  when designing the project, calculate all the bends and angles along which the pipes will run, especially the internal sewer system;
•  after completing the above steps, you can go to a specialty store for the purchase of materials.

Installation

Outdoor work

In the event that the house has an old system, it will be much easier for you. It is necessary to dismantle the old pipes and install new ones on the already prepared sewer paths.

However, a complete overhaul may be necessary, which includes raising the floor and deepening the trench if necessary:

• Dig a hole under the foundation and measure the width from top to bottom. The optimal value should be at least 100 cm, only in this case you can not worry about freezing the collector pipe;
• From the street side dig a trench to the drain hole. The depth of the trench outside should be greater than the inside and should be at a slight angle to facilitate waste flow.

You have to lay the sewer pipes inside the house and on the street.

1. At the bottom of the trenches, it is necessary to make a sand pad with a thickness of 20 cm. This will reduce the pressure on polypropylene pipes. That is, thanks to the sand, the buried soil will not put much pressure on the structure;
2. High-quality installation is impossible without proper sealing and connection of pipes. To do this, during installation, insert tees into the pipes, which will help you to eliminate blockages during operation. At this stage you should not save - this will all pay off very quickly;
3. Tees are installed in 4-meter increments, and the part reaching the surface is sealed with a plug.

Domestic sewage

Polypropylene pipes, which do not corrode, are often used for installation inside the house, and, accordingly, their service life is rather long, and the installation process is simpler than that of cast-iron or steel counterparts.

If you have a lot of plumbing, you need to choose a pipe with a diameter of 10 cm, while a pipe from a sink is 5 cm. That is, you will have to connect different pipes, which is done using adapters. Gaskets are used for reliability and tightness at butt points.

A revision (tee) is installed on the riser at a level of 1 meter from the floor, from which a pipe is drawn for extraction to a height of 70 cm from the roof surface.

Such a complex installation system will help you avoid unpleasant odors in the house, which accompany the installation of the sewer system. If ventilation is performed according to all requirements on the riser, then odors will not enter the room and cause discomfort.

Be sure to include the insulation of the riser, located in a cold room.

For joining the riser with an external sewer system, outlets are used whose diameter is smaller than the diameter of the pipe on the riser. According to professionals, the release should be mounted in the direction of the sewage at a right angle and be connected to the riser with two taps with angles of 135 degrees. If necessary, an additional riser will require the use of an oblique tee and an additional tap. If there is one riser or collector pipe, labor costs will be much less.

External sewage is made of polypropylene pipes Ø150 mm.

After reading the instructions and observing the technology of work, it is easy to equip your country house with the necessary communications.
