In a private house, it is impossible to create normal household conditions without sewage sewage. If the central communications are not available - the installation of an autonomous type sewage system is necessary. The home master will be useful will information about what equipment for this is necessary and how to perform work without attracting specialists.

What is good autonomous sewage

It does not require the use of pumping pumps and filters for the operation of autonomous sewage. Its action is based on the use of accumulative capacity in which wastewater falls along a pipe laid under the slope. The internal system has the following advantages over centralized:

• operation does not require significant expenses;
• ease of use;
• installation is possible in any terrain.

Important: The sewage device must comply with technical, environmental and sanitary standards regulated by SNiP 2.04.03-85 "Sewerage. External networks and facilities. "

Basics of the design of autonomous sewage

Sewage equipment must perform the following operation:

• collecting wastewater from all plumbing devices and household appliances connected to the water supply;
• displacement of waste water in the drive;
• purification of wastewater.

It follows from this that the main elements of the autonomous system should be:

• internal communications consisting of pipes connecting plumbing with external communications;
• claiming facilities (drive), which can serve as a cesspool or septic;
• external transport communications (pipes laid in Earth).

The main conditions for the functioning of the local sewer system

Designing the sewage system should be carried out at mandatory. It is possible to use ready-made solutions offered by various Internet publications. It is important that the following requirements take into account.

The sewage pipe is stacked into the ground under the slope

1. The slope of the outer tube, laid from the sinking of the sewage to the septica (cesspool) should not be less than 2 cm at the rate of 1 mongor meter.
2. The bias of the internal pipes should also have a slope. On average, the upper point of the 10-meter pipeline must be higher than the level of entry into the outer tube by 20 cm.
3. Plumbing devices attached to the system should be placed above the wastewater leading system (in order to comply with the first condition). Otherwise, it is necessary to use the pumping pump.
4. If it is necessary to organize a leading of wastewater from different levels of the building, the installation of vertical risers is necessary. They should be located next to the wall, at the bottom of which the sewage pipe is output (from the side of the septica).
5. Watering from the bathroom, sink, washing and dishwasher is performed using a pipe with a diameter of 50 mm, a pipe is 100-100 mm for the toilet bow.
6. So that the unpleasant smell does not penetrate the room, all plumbing devices must be equipped with hydraulic assets.
7. Revision hatches are provided for cleaning the pipeline from blocks. They are mounted in risers, in long spans and in places to change the direction of the pipe.
8. All elements of the internal system should be securely fixed by clamps to avoid its depressurization and reduce the angle of the slope. Hidden installation should also be performed with the fixation of the pipes and the subsequent sealing of the stroke.
9. The amount of septica (cesspool) is selected depending on the intended load on the local sewer.
10. It is necessary to avoid a large number of pipe turns. Connections at a right angle should be replaced by two compounds of 45 degrees: thus you can reduce the risk of clogging of the pipeline.
11. The depth of laying pipes of external communications must be lower than the level of soil freezing.

Installation of cumulative capacity

Important: Internal and external communications must consist of pipes and fittings made from one material (preferably one manufacturer). Otherwise, various thermal expansion of components can cause the system deployment.

Autonomous Sewer Construction Technology

The main stages of the construction of autonomous canadis

At the same time, an internal and outdoor sewer system can be constructed. The facilities are equipped with their own hands in accordance with the following procedure.

1. Before the start of land during the construction of external local sewage systems, the site markup is performed. The size and place for the septica are determined, the direction of laying the pipe.
2. The trench of the required depth is taken with the observance of the angle of the slope. At the bottom it is arranged a litter from a sand layer about 10 cm.
3. Pipes are stacked. It should be started from the wall of the house: it is easier to control the observance of the angle of the slope of the sewage. For connecting pipes, special couplings are used. After entering the pipe into the well (septicch) and sealing the place of input, the trench is covered with soil.
4. A well is built or the installation of a finished septic is performed. Multiple cameras with overflows should be provided: after filling the first chamber, the liquid fraction enters the second, then to the third chamber. The precipitate can be processed and neutralized by special bacterial agents.

Tip: The best for operational characteristics are the pipes and components for them, made from propylene and PVC (polychlorvinyl) with a diameter of 160-200 mm. Their smooth inner walls do not delay wastewater, which is important for communications having bends.

Options for the device of the accumulative and cleansing capacity of autonomous sewage

The following devices can serve as a sewer well.

Septic with reinforced concrete rings is condensed with a truck crane

1. Septicity of plastic: there is a relatively high cost and better characteristics of environmental friendliness, tightness, strength and duration of service life. It should also be noted ease of installation and ease of maintenance.
2. Well made of reinforced concrete rings. This design is not inferior in its operational qualities of plastic septic. Difficulties arise during installation: without powerful lifting equipment can not do.
3. Metal container. The main disadvantage is its instability to corrosion. Extend the service life can process the walls of the capacitance with special means.
4. Celdiction of bricks. This method of the sewage storage device can be the most acceptable for independent work. The disadvantage is the duration of the brickwork and concrete flooding.

Septicity of bricks

Important: When choosing a place for the septica, it is necessary to envisage the possibility of an entrance to the revision hatch of the assessing machine. The distance to the water intake should be the maximum possible.

To clean the cesspool used equipment based on an associate machinery

Ventilation of the autonomous sewage system

Ventilation of the sewer system is necessary to ensure comfortable living conditions in the house. Smells emanating from wastewater should be removed from the system. In order for ventilation to be quite effective, the rules must be followed during design and installation.

Exhaust pipe installed on septic

1. The exhaust pipe should rise to 1 m above the skate bar or the upper part of the roof. It is necessary to withstand the minimum distance to the windows - 4 m.
2. For integrated ventilation systems, which are a compound of multiple pipes, choose components of the same sizes (50-100 mm).
3. Exhaust ventilation should not connect with ventkalas at home.
4. A deflector is installed to enhance the thrust on the pipe.
5. Pipe of exhaust ventilation can be mounted on a septic tank or built into the sewer in the area between the wall at home and septic. Maintenance of the maintenance design should be provided (metallic or reinforced concrete column).
