Long gone are the days when a wooden freestanding structure was used as a restroom, as a rule, smelling not in the best way. Today, when constructing new houses, autonomous sewers are usually carried out. And in old buildings during the repair they try to re-plan the rooms in such a way as to allocate a separate room for the bathroom. And this implies a mandatory arrangement on the territory of the site of the purification device.
At the same time, a reasonable question immediately arises: "What is the best septic tank for giving?" Indeed, in the modern market there are so many various options that it is really difficult to choose from them. However, before deciding on a device for cleaning, it is necessary to consider in what mode it will be operated.
Factors affecting the septic tank selection
When deciding which septic tank is best for giving, it is necessary to take into account several very different factors that influence its choice.
Of primary importance is the purpose of the home, whether it is used year-round or only in the warm season.
In addition, it is necessary to roughly calculate the average volume of drains, which depends on the number of people living in the house. As well as the number of different plumbing units, for example, such as a washing machine or dishwasher.
It is very important to know the type of soil in the territory where the septic tank is planned to be equipped, this is necessary to justify the choice of a treatment plant. Will it be a storage septic tank or with a filtration system. It is also necessary to know the depth and place of the passage of groundwater so that sewage does not accidentally poison the water in nearby wells and water intakes. The mobility of the soil also affects the shelf life of the septic tank, if the soil is prone to displacement under the influence of environmental conditions, a container made of material of inadequate quality and thickness will soon become worthless.
It matters, when choosing which septic tank is better for giving, of course, and its cost, which can vary in the range of 20,000-500,000 rubles. The more modern the filtration system installed at the treatment plant, the higher the price of such a septic tank.
The device of septic tanks
There are two main types of purification devices operating on completely different principles: storage and purification septic tank. Which is the best for a summer residence, you decide, but first you need to understand what the fundamental difference between these types, and consider the pros and cons of each.
The storage device, in fact, is an improved cesspool, with all the ensuing consequences in the form of an unpleasant odor. In addition, the capacity of the septic tank has a limited volume, and the liquid has nowhere to go from it, it will be necessary to control the consumption of water washed into the pit.
Of the advantages of such a device, one can note its extremely simple design, which provides for simple installation. And also more than a reasonable price when buying. A similar septic tank of a small volume can be purchased even for 10,000-12,000 rubles.
Unfortunately, subsequently the operation of such a septic tank requires quite a lot of expenses on the call of sewage trucks and pumping the contents of the tank.
According to customer reviews, for the arrangement of the site, which are only in the summer, it is better to choose a storage septic tank. Which is good for giving? Basically, up to 10 cubic meters is considered optimal. Depending on the dimensions of the container and the manufacturer, the cost of plastic septic tanks ranges from 15,000-35,000 rubles.
Septic tank with filtration system
A cleaning septic tank is a more expensive cleaning device upon purchase, but more economical to use, since it will be much less necessary to call the wastewater collectors when properly installed. In addition, you will be spared from unpleasant odors, and the amount of water consumed per day increases significantly. Basically, such cleaning systems are used for operation in homes with permanent residence, where the volume of waste is quite noticeable.
Water purification and the decomposition of effluents is carried out due to the activity of oxygen-free bacteria (anaerobic septic tanks) or microorganisms that still require oxygen for normal life (aerobic treatment facilities).
Therefore, choosing septic tanks for giving (which is better for use in a winter cottage or in a country house), focus on the conditions of its operation. Owners who already use this device note that with good insulation it is preferable to choose an aerobic septic tank, although the cost of such a treatment plant is quite high, starting from 60,000 rubles. and higher.
How does a cleaning septic tank work?
A septic tank is a sealed container with separate tanks, passing through which contaminated water goes through several stages of purification. In the first section, preliminary screening occurs when heavy fractions settle and lighter float. In the second chamber, sedimentation continues; additionally, bacteria are purified. In the last third compartment, the final stage of purification takes place, after which the clarified water is discharged into the ground, passing through which it undergoes final complete filtration.
When deciding which septic tank to choose, which one is the best, study the filtration system in the tank. Today, the most popular septic tanks have a biological filter element of deep cleaning, which allows you to filter water by 98%.
According to reviews, such a system practically does not require the call of vacuum trucks, but the cost of such a septic tank reaches 500,000-600,000 rubles.
Varieties of containers for septic tanks
Similar septic tanks differ in the filtration system and the material for the execution of the sewage tank.
The tank can be made of stainless steel. Surprisingly, such a popular material in this case is not the best choice.
Firstly, it’s expensive (about 120,000-150,000 rubles), and secondly, even under the influence of aggressive substances in contaminated water, this material is subject to corrosion, which leads to a quick failure of the device. But he certainly does not emerge and is little susceptible to damage during seasonal movements of the soil.
Concrete tank
Such a septic tank is made of reinforced concrete, which has long been used to equip treatment facilities due to its strength and reliability. A controversial choice, since its installation will require a lot of costs, both monetary and time. However, a similar option is still popular among many when solving the question: "Septic, which is better?" - reviews on concrete performance are the most positive.
You can make a septic tank in two different ways. A simpler method, but requiring the use of special equipment, is the installation of concrete rings of the required diameter. Or, under the cleaning device, formwork is performed and the concrete solution is poured in stages. Which is better septic tank for giving of these two options - you decide.
Plastic septic tank
A good option is a plastic container, which has a reasonable price from 50,000 rubles. and has a fairly light weight that allows you to independently mount the device for a short period of time. However, when installing such a device, there is one small nuance: it is due to its light weight that it must be anchored or simply concreted. Otherwise, after a certain time, part of the septic tank may appear above the ground.
These rules need to be guided by choosing a septic tank. Which is good for giving from the above options? Pay attention to the thickness of the walls of the tank, the presence of stiffeners and the type of polymer used for its manufacture.
Choose a septic tank by tank volume
Returning to the question of the number of people living in the house, it is necessary to take into account that according to the rules, the cleaning device should easily contain the amount of effluent formed within three days. In order to make it clear, let's calculate the volume of a septic tank for a family of four.
For the average water consumption per individual, it is customary to consider a volume of 200 liters, which means that four will require 4x200 = 800 liters per day. For three days, it will be spent and fall into the septic tank 800x3 = 2400 liters. Since the volume of cleaning devices is calculated in cubic meters, one unit of which is 1000 liters, it turns out that for a family of 4 people, a septic tank with a reservoir of 2.5-3 cubic meters is needed.
As a rule, such small structures have two treatment chambers, which are quite enough for a complete disinfection of water. Tanks having a volume of up to 1 cubic meter usually have only one compartment, but over 10 cubic meters require three sections already.
What soil is your cottage on?
The answer to the question submitted in the subtitle determines which filter should be installed on the septic tank.
For loose loose soils, for example sandy, it is quite enough to use anaerobic closed septic tanks for giving, since the absorbing and filtering ability of such soils is quite high.
If your site has heavy clay soils, swampy or peaty soils, you must choose a sealed structure with biological or biochemical treatment. The same applies to the option with a high occurrence of groundwater. If this is not done, it is likely that after a while the entire contents of the septic tank will be under your feet with all the ensuing consequences in the form of smell and dirt.
It is necessary to carefully choose a septic tank. Which is better for a cottage, taking into account the specific type of soil on which it is located? In some cases, you can adjust the terms of use.
If there is loam on the territory of the summer cottage, this problem can be solved by additionally filling the sandy soil, however, this will require unaccounted monetary investments.
The influence of climatic conditions on the septic tank choice
This factor should also be considered when choosing a treatment plant, since soil susceptible to swelling under the influence of low temperatures can damage and damage the septic tank. What good septic tank will be in this case?
According to reviews, with a large heaving of the soil, it is better to choose a concrete structure, which is less prone to destruction. However, if the septic tank is properly insulated, the use of plastic containers that can serve year-round is quite applicable. At the same time, backfilling of a dug pit with a structure is carried out not with soil removed during excavation, but with sand.
The most famous manufacturers of treatment facilities
Today, a fairly large number of different septic tanks from different manufacturers are presented. Therefore, it makes sense to consider the most famous brands of cleaning devices and determine, a septic tank, which company is better to use in specific conditions.
The most widely represented in the Russian market are the cleaning devices Tver, Topas, Topol, Triton and Leader. Companies producing products under these brands, as a rule, produce cleaning septic tanks for summer cottages. Which is better, "Topas" or, for example, "Leader", it is difficult to say, since each of the manufacturers has its own advantage. When choosing a particular brand, first of all, be guided by the conditions of its use and stop at the most suitable option, taking into account all the above operation requirements. To date, the best reviews have received septic tanks "Triton" and "Topas", due to its affordable price of 20,000-30000 rubles. for the storage device and 80,000-90000 rubles. for a cleaning septic tank. Which is the best? We leave at your discretion.
