Sewage system in a private house: 4 steps of its arrangement

If you have a country house or at least a site on which you plan to build it, then you need to seriously consider connecting all the necessary communications to it. And if electricity can be drawn from a neighbor or a diesel generator can be installed, a sand or artesian well can always be drilled for water, then the situation with sewage is a special way.

Its arrangement is a whole art, which we will examine in detail in this article.

General provisions

Autonomous sewer systems for the house have some advantages over the central ones related to saving the family budget:

Merits

• The price of operation is limited only to cleaning and repair work arising as necessary, the communal fee is completely absent.
• Availability of installation and subsequent maintenance of their own hands.
• The possibility of using solid waste as a fertilizer for your garden, and purified liquid - in technical needs.

But in order to obtain savings through the use of its own local sewage system, it will be necessary to sweat once and spend money when installing all the necessary elements.

Structure

Exercise

Now let's step by step consider the order and features of the installation of a private sewer system.

Step One: the sewage treatment plant

As we noted in the table, this is the most important part of the entire sewer. As it can be used several options for structures, which in turn are divided into groups according to their functionality:

Let us analyze the main types in more detail:

1. Cesspit. The simplest and most used solution for collecting waste fluids.

Pros:

• Low implementation cost. As building materials, you can use old tires or bricks, used.
• Simple manufacturing instructions. The main tool is a shovel, special engineering skills are not required. That is, in fact, it all comes down to digging out a ditch and impose some inexpensive building material on its walls for the purposes of strengthening and waterproofing.

Minuses:

• The need for frequent pumping, which costs considerable finances. It is also worthwhile to also take into account the availability of a passage for an as-suction machine, which limits the use of the usable area of ​​the suburban area.
• The presence of unpleasant odors near the cumulative structure, which is incredibly strong in the process of pumping sewage.

Tip: it is recommended to equip an airtight cesspool. This will isolate fetid odors.

1. Septic tank. The most optimal option, taking into account the price and quality. Most often it is a ready-made plastic container, which is enough to immerse in the ground and connect to the highway. By the number of cameras and functionality, there are two types:

1. Station cleaning. They have different technical solutions and forms, but the main features boil down to the fact that they generally do not need the services of vacuum trucks. In them there are processes by which water becomes suitable for technical needs, and insoluble substances are transformed into excellent fertilizers, and all this with minimal intervention.

The only thing to consider is:

• The high cost of such equipment;
• The need for a permanent connection to the power supply.

Advice: it is more profitable to buy and install such powerful systems in clubhouse on several nearby houses. Their performance will be enough, but the cost will be much lower for each owner.

Step Two: Main Pipeline of External Pipeline

Best for connecting a septic tank and home plumbing special sewer pipes made of polyvinyl chloride with a diameter of 110 mm. They have light weight, sufficient strength and are equipped with a variety of different connecting elements.

During the installation of the pipeline should follow some very important rules:

1. The depth of the trench should be below the level of soil freezing to prevent freezing of fluid in it in winter. In case it is too expensive or not at all possible, be sure to take care of the structural insulation.

Tip: to increase the heat insulation of the sewer pipeline, it is best to apply the “sandwich” technology, which is that you thread the PVC product into a pipe of a larger diameter, and fill the gap between them with mineral wool, polyurethane, felt or other insulation material. So, you guarantee the safety of insulation for many years.

1. Start the installation made from the cumulative structure.
2. Observe a suitable slope in the direction of the septic tank, which is 20 mm per 1 m. A smaller one will weaken the pressure that insoluble particles cannot pull, and with a larger water it will not have time to seize the garbage.

1. Try to eliminate any bends, as they are subject to rapid clogging and traffic jams. In the event that a sharp turn is still unavoidable, then install a rotary sewer well at this point.

Step Three: Internal Pipeline

Domestic sewer systems for a country house are also equipped with PVC pipes, as well as the main highway, only of smaller diameter.

It should follow the following recommendations:

1. The size of the cross section of each pipe should not exceed the value of the radius of the output line. More accurate values ​​are always indicated in the instructions of the connected equipment.
2. Each drain point must be equipped with its own water gate, which serves to protect the room from the penetration of unpleasant odors.

1. It is not necessary to connect two thin pipes into one of the same diameter, use for this an analogue of the main drain.

Step Four: Ventilation

All sewer systems for a private house must be equipped with ventilation.

Otherwise, you will find:

• The accumulation of gases in the septic tank, which can lead to unpleasant consequences during its cleaning.
• Discharge of air in the system, the result of which will be the disappearance of water in hydraulic locks.

Thus, in order to protect your home from the penetration of the waste scents of the water seal is small, it must be strengthened by creating high-quality ventilation, which is implemented by one of two methods:

1. The fun pipe. For this, a PVC product is also suitable, which is derived from the sewer line up to a height of one meter from the roof. It will be quite enough for high-quality ventilation of the entire system.
2. Vacuum valve. A special device that is installed directly on the drain and is triggered if the air inside becomes discharged. In this case, the lid opens to equalize the pressure, then slams.

Conclusion

The sewage system of a private house is set in four steps, which we described in detail above. It is important to choose a reservoir suitable for your needs for the accumulation and processing of wastewater, lay the main pipe, conduct internal wiring and take care of high-quality ventilation.
