Topas, Tver or Astra - choose the best septic tank for your home in 2021

There is a sanitary standard according to which the size of the septic tank must take into account the number of people living in the house. The calculation is based on the fact that each resident discharges 200 liters of fluid daily. Of course, the parameter is conditional and it is very difficult to achieve such a value. In any case, manufacturers try to stick to the norm.

Accordingly, most models have a capacity of 0.8 cubic meters per day. With the exception of two septic tanks from our list: Tver-0.75 PN and Unilos Astra 4. They have a slightly lower value - 0.75 cubic meters. This is not fatal and also fits the standards, so you can safely install a septic tank without fear of sanctions from the sanitary services. But, as they say, the pocket does not pull the stock, and the larger the specified parameter, the better. Yes, the difference is small, but it exists, which means that the models from Eurolos, Biodeca and Topas, although not by much, outperform their competitors.

Volley reset is another important parameter.It shows how much liquid the system can take at the same time. There is a calculation scheme in which each item of the bathroom, as well as household appliances, produces liquids at the same time:

Based on this, the salvo discharge that you need is calculated. That is, we simply take all the points available in the house, and add them together.

All the models presented have this parameter different:

1. BioDeka-4 C-700 - 190 liters;
2. Eurolos Bio 4 - 180 l;
3. TOPAS-S 4 - 175 l;
4. Tver-0.75 PN - 190 l;
5. Unilos Astra 4 - 180 l.

It cannot be said here that the best septic tank is the one with a higher salvo discharge. In some cases, these values ​​can be oversized. In addition, a one-time discharge of water from all points in the house is unlikely. But then again, a stock is a stock, and it is never superfluous. However, the difference between the contestants is small.

Comparing septic tanks by weight is the most difficult. On the one hand, it is good if the structure weighs a lot, since it will be easier to fix it in the ground and the probability of its displacement is lower. On the other hand, it will be more difficult to install such a system, and if one day it nevertheless shifts due to the buoyancy of the soil or other nuances, then it will be much more difficult to return it to its place.

As for our contestants, the easiest is Unilos Astra. It weighs only 120 kilograms. A little heavier than Eurolos and Biodek. They weigh almost the same, just over 130 kilograms. Tver is heavier by another 10 kg, and the record holder is the product of the Topas brand. It weighs 215 kilograms and this must be taken into account during installation. Putting such a unit in a pit without the help of special equipment will not be easy.

Septic tanks are either horizontal or vertical. The best option in this case is the one that best suits your site. If there is a high occurrence of groundwater, it is optimal to take a horizontal option. It does not need to be buried deep and there will be less contact with water. But on the other hand, such a septic tank will take up a lot of space in the horizontal plane, which also needs to be taken into account.

Vertical models are the most common. They are quite narrow, so they do not take up much space, but they require digging a deep hole. Often more than two meters. There is another important nuance - cleaning. It is enough to read reviews on the network to understand that it is much more difficult to clean a vertical septic tank. The sludge accumulates in the lower part of the tank, which is not easy to get to, and a lot of equipment has to be dismantled. Horizontal models are more convenient in this regard.

As for our competitors, the only horizontal model among them is Tver. All others are vertical. You should also pay attention to the dimensions of the structure. The question is individual, but it is better to know the dimensions of the septic tank even before the moment of its purchase:

Despite the different dimensions, the internal cubic capacity of the system remains almost the same. This is due to the technical equipment of septic tanks and the equipment that is installed in them. As for what size is best for a septic tank, let's take as a basis the fact that you need to save space. That is, the less space the septic tank takes on the site, no matter in which direction, the better.

A parameter that is often overlooked when choosing a septic tank for your home. After that, reviews appear on the network that sewer pipes froze in winter. In fact, it is very important, and there are freezing standards calculated for each specific region of Russia. It does not make sense to list them all, but if we generalize, they will look like this:

Accordingly, if you live in the south and buy, say, Unilos Astra, which has a depth of 85 centimeters, then you can safely mount it without insulating pipes at all. But in the north it is better to use additional insulation.At the Tver septic tank, the pipes run at a height of 32 to 52 centimeters, that is, even in the south, insulation of the tray will be required. Topas, Eurolos and Biodeca are leaders in this comparison, since they not only have a good depth of 80 centimeters, but also a decent range, where the smaller value is only 40 cm.

Deep cleaning septic tanks need electricity. It powers pumps, compressors, and in some cases other life support systems. The consumption is constant, that is, even if the septic tank is not used, it still works, which means it is powered by the network. It is very important here that the system is economical and at the end of the month you do not see huge amounts in the payment.

It is worth noting that all modern manufacturers are trying to reduce energy consumption as much as possible, but there is still a difference. The best option in terms of savings is the Tver septic tank. For a day, it winds only 1.2 kilowatts. Unilos Astra will take a little more - 1.33 kW. Eurolos and Topas can be attributed to the middle category. They have this value set at around 1.5 kW. And Biodeka becomes the most voracious - 1.6 kilowatts per day. However, the difference in values, apparently, is not significant.

Reading reviews about various septic tanks, you can often see the following: over time, the design began to shift, which led to a violation of the integrity of the sewer system. In fact, this is not a problem of a septic tank, but of its installation. Floating soils and seasonal deformations of the soil put pressure on the structure, and if it is not fixed correctly, then sooner or later the same displacement will occur. The stronger the tank is mounted, the better. Accordingly, the best septic tank is the one that has the most fasteners and special technological holes.

The leader here is Biodeca. This septic tank is attached both through the bottom, for this it has an enlarged platform, and from the sides, where there are lugs, and on each side. A product from Eurolos has a similar design. Moreover, thanks to the tapering neck, it becomes possible to further strengthen the tank. Septic tanks Yunilos Astra and Topas do not have an enlarged area. They are attached exclusively to the sidewalls. Both models have lugs, but only on two sides. And the most difficult thing will be with the Tver product. It doesn't have any mounting lugs or pads at all. You'll have to come up with something on your own.

A deep cleaning septic tank is not cheap, but it is the best option if your house is not connected to a central sewer. Compared to a conventional storage pit, you will still win in the long run.

All the brands presented in our article are Russian, but with almost the same characteristics, the difference in price can reach 50 thousand rubles. The cheapest option is offered by Eurolos. Its unit will cost 85 thousand. A tank from Unilos Astra costs a little more, 87 with a little thousand. Biodeca will cost even more, about 95 thousand. And the most expensive options are septic tanks from Topas and Tver. The first costs about 115 thousand, and the second 130 thousand rubles.

And this price is not final. In addition, the services of installers will also be required. Most brands do the installation themselves. In this case, you receive a warranty and service for a certain period. So, the Tver company promises to take care of the septic tank for two years, which partially offsets the price tag. In addition, the horizontal unit is easier to mount. You do not need to dig a deep hole, which means that the cost of installation work will be lower.

Based on the totality of all criteria, the septic tank of the BioDeka-4 S-700 model becomes the winner. Almost nostril to nostril with him is the product of the company Eurolos Bio 4. And the horizontal septic tank Tver-0.75 PN is gaining the least points.

Choose the BioDeka-4 C-700 and Eurolos Bio 4 models if you care about:

• performance;
• economical energy consumption;
• convenient and easy installation;
• attractive price.

Septic tanks Unilos Astra 4 and TOPAS-S 4 are suitable for those for whom it is important:

• compact dimensions;
• deep sewer pipes.

And the Tver-0.75 PN model will be an excellent solution for large houses, where the main criterion is the maximum burst discharge. In this nomination, this septic tank is out of competition, although in other respects it loses somewhat to its competitors.
