There is a huge number of types of non-volatile septic tanks for use in cottages. This acquisition is economical and relevant today.
A cottage for electricity without electricity
When building a house, there is often a question of sanitation. The simplest solution is to use a septic tank. A septic tank is a special facility, the main purpose of which is the purification of domestic wastewater. And the cleaning up to the required sanitary standards. This device is universal and very simple to operate. To make the device work as long as possible, it is enough just to carry out cleaning and disinfection. And they are held, on average, once a year.
The main advantage of such a device is its non-volatility. All his principles of work are based on the laws of physics and chemistry. Externally, such a device, most often, resembles several containers, united by pipes, as in the figure below.

Such a system is absolutely independent and does not require any human intervention. In addition, periodic cleaning and disinfection. For the convenience of the potential owner, several different types of such devices are proposed. They can differ in their modifications, in volume, as well as in design features. For today, the following models are offered:
- Made of concrete - read the article with a self-contained septic tank of concrete rings;
- With metal bodies;
- Models purely of plastic.
Regarding the choice of devices, it is necessary to consider in detail all types, or rather materials of manufacture. For example, a concrete septic tank is capable of withstanding enormous loads, it is perfect to cope in any climatic and weather conditions. However, there is a significant disadvantage - such devices have a lot of weight, they are extremely difficult to mount.

At the same time, metal products have significantly less weight, respectively, and are mounted very simply. Here, even one person can cope for a short period of time. But metal products have their own drawback - they are prone to corrosion. Accordingly, the period of their operation is significantly reduced.
Sample metal septic
The peculiarities of plastic septic tanks include the fact that they perfectly resist corrosion, do not rot and do not deteriorate. They are absolutely airtight. Again, their weight is much less than that of metal, this is a plus, expressed in the ease of installation.

But they also have their own drawback - plastic septic tanks are subject to mechanical stress.
Use of finished plastic septic tanks
If you need a cleaning device for a summer house, the best solution is to purchase and install a finished plastic septic tank.
Many people are afraid that they will not be able to choose the optimal device without a specialist, however, despite the abundance of various models, shapes and designs, the principles of operation for similar septic tanks are the same - the device includes several cameras that are connected by special systems for fluid transfer and filtration.
Varieties of plastic septic tanks
The plastic septic has many advantages:
- It features minimal weight, unlike devices made from other materials. Accordingly, this factor directly affects the ease of transportation, loading and unloading, installation in the right place. Moreover, the installation of such a device can be carried out without the need to employ specialists or equipment;
- Plastic is not susceptible to the influence of an aggressive environment, and it is also not susceptible to sewage drains. So, it can work very long;
- An interesting feature will be the complete airtightness - you can exclude any chance of penetration of un-treated drains into the ground.
Choosing the optimal septic tank
The septic tanks differ also in their manufacture. More precisely, according to the polymers from which their body was made. For example, in today's market you can easily meet septic tanks made of polyethylene. They are best suited for work in conditions associated with an aggressive environment, or with large temperature differences.

Septic tanks made from polypropylene, have less strength, but are more solid, characterized by high resistance to various erasures, etc. Actually such a device for work in high temperatures. Unfortunately, this species is very prone to corrosive cracking. It is optimal for use in industrial effluents.

The next type, a septic tank using fiberglass, looks like a container divided into several chambers. Due to the fact that here one of the main materials of manufacture is fiberglass - the container is not susceptible to corrosion. Moreover, if you acquire such a model, you can not be afraid for its strength - such a septic tank is able to withstand the pressure of the soil, and even during periods of freezing and thawing. Another advantage is that when installing such devices it is not necessary to install concrete formwork or sarcophagi.
It is the correct installation of a septic tank that will allow it to work not only as efficiently as possible, but also as long as possible.

Detailed installation process for
Before proceeding to the basic operations, it is necessary to determine the place that, according to the requirements of the SanPin, must be remote from the apartment house, at least 5 meters.
Determine the distance from the well to the septic tank based on the sanitary standards
In this case, the installation point is best laid straight, without any knees or turns. If you do not leave the turns, you should also install wells with which you can check the condition of pipes and knees.
Once you have decided on the place of installation of the tanks, you need to start digging pits, which should be somewhat larger in size than the septic tank you have purchased - this will facilitate installation.
The larger pit should be torn and in order to make a special concrete sarcophagus. It is he who will protect the light plastic construction from various mechanical damages, or loads from the ground.
Concrete sarcophagus to protect the septic from the pressure of the soil
As you can see in the figure, the sarcophagus device involves reinforcing the walls with boards, using formwork, as well as laying the mesh out of the reinforcement. Then you can pour the concrete mixture itself.
To anchor the anchor belts, you should use stainless steel bolts and attach them to the framework of the armature.
You have to let the concrete dry, it takes about 2 weeks. At that time, it is possible to tackle the pipeline. At the end of these works, a layer of sand( about 20 cm) should be poured onto the bottom of the pit.
Regarding installation of the septic tank itself - it should be installed to a depth of about 1.5 meters. It should be filled with water, that would eliminate the risks of damaging its walls with soil.
If you want to insulate a septic tank, sand or polystyrene should be placed between the container and the edges of the pit.
It would be easier to navigate the depth, as well as the features of the installation, you can look at the proposed figure below, which can be called the standard, optimal and correct installation option for a septic tank.
