About such a device as a septic tank, negative reviews can be heard quite often. Nevertheless, this type of wastewater purifier is quite naturally popular among owners of suburban real estate. Let's try to figure out why such actively used equipment is subject to frequent criticism, and how justified it is.

How it works and operates
tank type installation
This type of septic tank is made from durable thick plastic using a technology that does not imply the presence of seams on the product. The design is a one-piece body with several interconnected compartments. The walls of the body are made using a large number of stiffeners, which ensures good resistance of the material to external pressure from the soil layers. Most often, there are three compartments, and they are interconnected by overflows in the upper part of the device.
In addition, infiltrators are supplied with a septic tank, of which there can be from 1 to 4 or more. They are containers in which water is passed through the soil layer, which contributes to its almost complete purification of impurities. The manufacturer believes that the water leaving the treatment system is 98% pure. This allows it to be used for technical purposes. In the pipe between the infiltrators and the septic tank is installed check valvethat prevents water from returning back when the filters are full.
From the sewage system, water and sewage enter the first chamber of the septic tank, where settling and precipitation of solids occurs. The liquid is poured into the second compartment, where it is further purified using bacteria that decompose organic matter. After that, sufficiently purified water enters the third chamber, where suspended particles precipitate.
Liquid enters the infiltrators, which requires only final post-treatment. It is with the use of infiltrators that a large number of negative reviews are associated. A septic tank, when using these post-treatment devices, takes up a lot of space on the site, and this does not suit everyone.
Technical characteristics of tank cleaning devices for domestic wastewater
The main characteristic of any septic tank is its performance. When choosing a device, you must consider it first. Tank septic tanks are available in five types, which differ in size, performance and cost:
- Tank 1 is capable of servicing at least 3 people, has a capacity of 600 l / day, at a cost of about $ 400, and its dimensions are 1200x1000x1700 mm.
- Tank 2 is already designed for 4 people with a capacity of 800 l / day. Its cost is 550 USD, dimensions are 1800x1200x1700 mm.
- Tank 2.5 can process wastewater from 5 households, since with dimensions of 2030x1200x1850 mm, it is able to pass through itself 1000 l / day. True, and its cost is impressive - $ 700.
- Tank 3 processes wastewater with a volume of 1200 l / day from 6 persons with dimensions of 2200x1200x2000 mm and already costs 830 USD.
- Tank 4 is the largest 3800x1000x1700 mm, which provides it with a capacity of 1800 l / day. It is installed if the house is home to from 7 to 9 people. The price of such a device is more than 1000 USD.
As you can see, you can buy a septic tank for almost any family. Negative reviews on it are often caused by the wrong choice of device performance. Trying to save money, people buy a cheaper septic tank, which is designed for fewer residents in the house than there actually is.
Septic tank, negative reviews and how much
they are justified
If you study the opinion of consumers regarding Tank septic tanks, you can see that they are very often criticized. Let's take a look at the most common negative reviews for this device and try to understand the reason for each of them.

Opinion on the need to clean containers
“We have been using the septic tank Tank 2 for 3 years already. Works flawlessly. However, every year you have to pump it out, and this is a troublesome business. The site is located in a gardening partnership far from the city. It is expensive to call a flusher there. You can pump out the sludge yourself with a drainage pump, but it is also expensive, and where to put this waste. "
Nikolay Usoltsev, 45 years old, Saratov
What can I say about the validity of these claims? Yes, of course, any device needs periodic maintenance. This is indicated in the passport for the septic tank. Moreover, its periodicity should not be violated, since the solid sediment can be compressed so that it cannot be pumped out. In any case, calling the flusher once a year is cheaper than calling it every 2 weeks when using a regular capacity as a drive.
Useful advice! If you purchase a drainage pump, then the substrate processed by bacteria from the septic tank can be pumped directly into the garden. This mass is an excellent fertilizer. Do not be afraid of the smell, bacteria have minimized it, and if it gets into the air, it will completely disappear in a couple of days.
Claims to the overall dimensions of septic tanks Tank
“The father-in-law has a septic tank installed on the site. I recently built a house and also decided to install a similar device for myself, but when I looked at how much space it needed, I was horrified. The test-law is good - he has 20 acres, and I have only 4. I believe that the need for a large area for installing this device is a serious disadvantage. "
Sergey Nikolaev, 27 years old, Petropavlovsk
Indeed, for the installation of any septic tank, a tank requires a fairly large amount of space, since it is equipped with infiltrators. They can be, depending on the number, up to 6 meters in length. To this we add the septic tank itself and pipes. It will turn out to be an impressive area.If there are trees and outbuildings on the site, it may be impossible to install it.
Useful advice! Agree with a neighbor and buy a septic tank in a club. If you have small areas, then by combining, you can find a place for cleaning devices. Moreover, then it will be possible to pump out in turn.
Impossibility of using plastic septic tanks Tank with high groundwater levels
“I installed a local treatment plant Tank near my house. Even when they were buried, there was water at the bottom of the pit. The neighbor warned that the container could squeeze out, but I did not listen. And so it happened this spring. The tank floated to the surface, breaking the entire system. I would not advise anyone to buy these plastic barrels. "
Alexander Petrov, 32 years old, Tyumen
It has already been repeatedly noted that before installing a septic tank, it is necessary to clearly study all the geological features of the site, including the water level in the ground. Naturally, the light container floated up in the spring when the level rose. In such cases, it is necessary to arrange other types, for example, septic tank made of concrete rings or use helpful advice.
Useful advice! In order not to have to make a negative review, the septic tank should be anchored with a seasonal high rise in groundwater. To do this, drainage is arranged in the pit and a reinforced concrete slab with hinges is lowered there. For these loops, the container is tied with slings. The container should be filled with a mixture of sand and gravel.
Reviews due to violation of operating conditions
Septic Tank Tank
“I buried a septic tank Tank 1 last year. My wife and I together live in a house and we have enough of this volume. A month ago, the children with their grandchildren came to visit. There were 8 people in the house for a week. On the 6th day everything was flooded. I called the masters. They said the pipe was damaged due to overload. Is the material so fragile that it could not cope with the flow of water. "
Evgeny Pavlovich, 59 years old, Omsk
The situation speaks for itself. You can not use a septic tank with a lower capacity than required by the standards. This leads to overloading and flooding. In this case, even a breakdown occurred. If you even live together, but know that you may have frequent guests, buy a device with a higher performance.
Most of the negative opinions on the septic tank on the forums are due to a violation of the conditions of its operation or imprudence when purchasing. Therefore, before purchasing a septic tank Tank, carefully weigh all the circumstances, and during operation try to adhere to the manufacturer's recommendations.
