Device and features of installation of external Sewerage

When thinking about building a country house, you always need to start with drawing up a project And since everyone wants to live as well as possible, various kinds of amenities are an integral element of any home One of them is the sewer system But it consists not only of pipes that are located inside the house and connect all plumbing equipment A mandatory element of this system is the street sewer

General information about outdoor Sewerage

As already noted, there are two types of Sewerage – internal and external The first consists of pipes connected to the riser External Sewerage consists of collectors located on the street and connected in a single system-from the riser to the place of water discharge To put it more clearly, the external sewer system consists of many collectors United in a single network and designed to discharge feces and other sewage The street sewer is connected to the village collector In terms of structure, the external sewer system consists of several elements-wells, purifiers, and a pipeline Each of these elements has a specific meaning and performs a specific function for it

The main function of outdoor Sewerage is to move waste water and other emissions outside the settlement, which is designed to purify water and the environment After cleaning, it is necessary to check that if wastewater enters the natural environment, its condition does not change

Basic requirements for sewer pipes

When selecting sewer pipes for an external system, it is necessary that they meet certain requirements In particular, it is necessary that these pipes have a relatively low weight, are reliable even with sudden temperature changes, and are practical (that is, they do not require much effort during installation)

Features of cast iron pipes for external Sewerage

Until a few years ago, cast-iron pipes were almost the only material used to make outdoor sewer systems However, the fact is that cast iron, in comparison with other materials, has a lot of disadvantages First of all, they are quite heavy, and also are not able to be used for a long time, since a plaque appears on the inner surface of such a pipe over time, as a result of which its diameter decreases

In addition, cast iron pipes are easy to corrode And given the fact that the external sewer is constantly in interaction with the surrounding air, it is completely impossible to protect yourself from corrosion In addition, cast-iron pipes must somehow be transported from one place to another, which requires specialized equipment Therefore over time cast iron products went out of mass consumption and were replaced by their PVC and polypropylene structures

Advantages of plastic pipes intended for external Sewerage

Compared to cast iron plastic pipes have a lot of advantages They easily tolerate even strong temperature changes, are reliably protected from corrosion and exposure to all kinds of harmful substances In addition, their weight is much less than that of metal pipes, and transportation does not require additional equipment And of course, the service life of plastic pipes is several times longer than that of cast iron

Features of installation of external Sewerage

It is quite possible to lay an external sewer yourself – this does not require any special skills Let's take a closer look at the installation process Its peculiarity is that it takes place in several stages

Features of the external Sewerage project

The project of external Sewerage is the same mandatory element as the project of a residential building If you purchase a standard project or order an individual one during construction, you will not need to create anything additional You can buy materials and start installing the sewer system without any hesitation But some people try to create projects on their own There is absolutely nothing wrong with this, but it is desirable to show the finished project to a specialist The fact is that when preparing a project, you need to take into account a lot of parameters If errors occur it will be extremely difficult to correct them later The place for digging a septic tank must be selected in such a way that sewage can not get into the ground When sewage gets into the basement, too, there is absolutely nothing pleasant In addition, the finished project should provide for the possibility of driving a sewage disposal machine to the site of the pit, since the contents will have to be pumped out periodically

Step-by-step instructions for installing an outdoor sewer system

Step 1 Digging a hole

After the project has received approval from experts, you need to decide whether you will dig a cesspool or install a special container

The depth of the cesspool should be approximately one and a half meters (this is the minimum mark) The main rule is that it should be dug below the freezing level, but it should not approach the ground water When equipping the pit, you need to install 2 rings made of concrete, thanks to which you will prevent the earth from crumbling In the case of using a septic tank, it is recommended to make a small hole at the bottom, through which water will go into the ground The minimum volume that is allowed for a septic tank is about three daily volumes of runoff water, which is drained by all residents of a particular house In addition, a water filtration and purification system should be provided so that it can flow freely into the ground To achieve this goal, it is recommended to install a drainage system that is part of the sewer system When using drains, the water is purified by about 70 percent, which is enough for its removal to the ground

The septic tank should be made in such a way that it is as tight as possible Otherwise, there is an increased risk of outflow of runoff water into the ground, resulting in the latter being polluted And this, in turn, is not only unacceptable from the point of view of ecology, but is also prosecuted by law!

Step 2: insulation of the septic tank

Since the depth of the cesspool must be below the freezing level, if the temperature is too low, putrid bacteria stop their activity All this eventually leads to the fact that the surrounding soil is polluted Since this can not be allowed in any case, it is necessary to equip the septic tank with a material that can retain heat The most suitable in this regard is PENOPLEX, plates of which are installed on the sides

Step 3: digging the trench and installing the pipes directly

The depth of the trench should be about one meter As for the pipes, it is recommended to sprinkle them with sand and cover them with insulation, so that in the event of severe frosts, they do not freeze from the inside

Step 4: Connecting the pipe to the septic tank

At the same time, the connection should not be stationary, since movement is necessary to prevent freezing of the pipe in the winter season Otherwise such a pipe may simply burst and then it will have to be changed The pipe should go into the well in such a way that its end slightly looks out of the pit, but the neck remains inside

In General Sewerage should be provided and carefully thought out at the initial stage of construction To do this, at the beginning of construction, insert an asbestos pipe near the place where the riser will come out After the pipe is brought to the house, it is necessary to connect all internal plumbing and other equipment to it

Step 5: the Final stage

After the pipeline is fully connected, it must be checked before filling in the ground To do this, connect the water at full capacity and see if there is a leak anywhere If you find something non-standard, you need to quickly correct all the identified shortcomings

If your house is two-storeyed or more, then an integral element of the external sewer system is the supply of pipes to the roof It is necessary in order to be able to collect rainwater and remove it to the ground At the same time, the system must be equipped in such a way that further maintenance does not cause any difficulties
