Villas, as a rule, do not have a connection to a centralized sewage system, so the installation of an autonomous system is a vital necessity. However, in a small area, such as a cottage, the periodic entry of a special vehicle for cleaning the cesspool is extremely difficult, or impossible without damage to the plantations. Today we will talk about choosing a septic tank for a dacha.
Recently, more and more often began to install systems that allow to purify waste water. In them, one of the most important elements is a septic tank, for example a "tank", the installation of which I have already written. It is a reservoir that has internal partitions that divide it into separate sections. The impurities that have passed through it are cleared by 60 to 80%( depending on the model), and only their additional processing is needed.
Rules for choosing a septic tank
When choosing a septic tank, you should pay attention to the following:
How often and how many people are in the suburban area?
If you only come there periodically, for the whole day on weekends, then the simplest septic tank is enough. You should focus on products with a daily throughput "capacity" of about 500 liters. Such models are single-chamber and are cheaper than others. If someone in the dacha permanently resides, then this design is quite enough to ensure the livelihood of 3 - 4 people.
But you need to keep in mind that a single-chamber septic tank requires regular cleaning. If the family is big or the guests constantly come to the dacha, then it is better to stop the choice on the septic tank, working together with the filtration system( trench, well).However, in this case there are certain restrictions on the soil.
At the same time, the sizes of the septic tank( hence, the model) are selected based on the available space in the plot. It should also be taken into account that a septic can not be put anywhere. There are some rules for choosing the right place. And it's not a fact that if there is a place, it fully meets the requirements.
vertical and horizontal septic tanks
Material from which the
tank is made. Specialists recommend choosing a septic tank with a plastic body. First, such products are easy to install locally. Secondly, the septic tank is located in the ground, it is affected by moisture. A plastic corrosion is not terrible.
If it is installed in the soil with the presence of aggressive elements, it is better to buy a septic tank made of polyethylene. It also works well for sudden temperature changes. The polypropylene housing is more robust, at the same time it can be used in a larger temperature range.
Version - vertical or horizontal
The vertical model is better suited for areas with low groundwater levels. Its dignity lies in the fact that to install the tank does not need a lot of space - in fact it's a barrel with a lid. However, the depth of excavation should be appropriate.
Horizontal models are similar to a tank. The number of covers corresponds to the number of sections. Therefore, with a relatively small depth of installation, such septic tanks occupy a much larger area.
Principle of operation
Septic tanks are divided into aerobic and anaerobic. In aerobic reservoirs, the purification of impurities takes place with the help of bacteria. To ensure their life in the septic tank must be fed oxygen.
The work of anaerobic septic tank is based on fermentation of waste( organic matter).To increase the efficiency of the work inside the tank periodically( according to the instruction) activating substances are added.
The most reliable option is to use both types of cleaning when creating an autonomous sewage system. In other words, at least two sections.
