On a device like a septic tank, negative reviews can be heard quite often. Nevertheless, this type of wastewater purifier is quite naturally popular with the owners of suburban real estate. Let’s try to understand why such actively used equipment is subject to frequent criticism, and how well it is justified.
How is the structure and functioning
tank type installation
This type of septic tanks is made of durable thick plastic using technology that does not imply the presence of seams on the product. The design is a solid body with several interconnected compartments. The casing walls are made using a large number of stiffeners, which ensures good resistance of the material to external pressure from the layers of the soil. 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, which can be from 1 to 4 or more. They are containers in which water is passed through a layer of soil, which contributes to its almost complete purification from impurities. The manufacturer believes that the water at the outlet of the cleaning system becomes 98% clean. This allows you to use it for technical purposes. A check valve is installed in the pipe between the infiltrators and the septic tank, which prevents water from returning when the filters overflow.
From the sewage system, water and sewage enter the first chamber of the septic tank, where sedimentation and precipitation of solids take place. The liquid is poured into the second compartment, where its purification takes place using bacteria that decompose organic matter. After that, the already sufficiently purified water enters the third chamber, where suspended particles precipitate.
Fluid enters the infiltrators, which requires only final purification. It is with the use of infiltrators associated with a large number of negative reviews. A septic tank, when using these devices after treatment, takes a lot of space on the site, and this does not suit everyone.
The main characteristic of any septic tank is its performance. When choosing a device, it is necessary to consider it first. Septic tanks are available in five types, which differ in size, performance and cost:
- Tank 1 is capable of serving at least 3 people, has a capacity of 600 l / day, at a cost of about 400 USD, 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 cu, its dimensions are 1800х1200х1700 mm.
- Tank 2.5 can process wastewaters from 5 households, since with dimensions of 2030x1200x1850 mm it is able to pass 1000 l / day through itself. True and the cost of it is impressive – $ 700. e.
- Tank 3 handles drains with a volume of 1200 l / day from 6 persons with dimensions of 2200х1200х2000 mm and costs already 830 cu.
- Tank 4 is the largest 3800x1000x1700 mm, which provides it with a capacity of 1800 l / day. It is installed if the house is from 7 to 9 people. The price of such a device is more than 1000 USD.
As you can see, for almost any family you can buy a septic tank. Negative feedback on it is often due to the wrong choice of device performance. Trying to save money, people buy a cheaper septic tank, which is designed for fewer tenants in the house than it actually is.
If we study the opinion of consumers regarding the septic tanks Tank, then we can see that they are often criticized. Let’s analyze the most common negative reviews on this device and try to understand the reason for each of them.
Sewerage in a private house: the scheme, the depth of installation. Features of mounting your own hands and its order. Carrying out the necessary calculations in the design of the interior of the sewer system.
“For 3 years we have been using the septic tank Tank 2. It works without complaints. However, every year it has to be pumped out, and this is troublesome. The site is located in a garden partnership far from the city. To call there the nightman is expensive. It is possible to pump the precipitate independently with a drainage pump, but it is also expensive, and where to put this waste. ”
Nikolay Usoltsev, 45, Saratov
What to say about the validity of these claims? Yes, of course, any device needs periodic maintenance. This is indicated in the passport to the septic tank. Moreover, its periodicity should not be disturbed, since the solid precipitate can be compressed so that it cannot be pumped out. In any case, calling a vacuum truck once a year is cheaper than calling it every 2 weeks using a conventional capacity as a drive.
Helpful advice! If you buy a drainage pump, then the substrate processed by bacteria from the septic tank can be pumped directly to the garden. This mass is an excellent fertilizer. You should not be afraid of the smell, the bacteria have minimized it, and when released into the air, it will completely disappear in a couple of days.
“In the test at the site is a septic tank. I built a house recently and also decided to install a similar device for myself, but when I looked at how much space was needed for it, I was horrified. The test is good – he has 20 acres, and I have only 4. I believe that the need for a large area to install this device is a serious disadvantage. ”
Sergey Nikolaev, 27 years old, Petropavlovsk
Indeed, a sufficiently large amount of space is required for the installation of any septic tank, since it is equipped with infiltrators. They can take, depending on the number, up to 6 meters in length. To this we add the septic tank itself and the pipes. Get an impressive area. If there are trees and outbuildings on the site, it may not be possible to install it.
Helpful advice! Agree with a neighbor and buy a septic tank in the clubhouse. If you have small areas, then together, you can find a place for cleaning devices. Moreover, then it will be possible to pump out one by one.
“I installed a local tank treatment plant near my home. Even when they were buried, there was water at the bottom of the pit. Neighbor warned that the capacity can squeeze out, but I did not listen. So it happened this spring. The tank floated to the surface, breaking the entire system. I do not advise anyone to buy these plastic barrels. ”
Alexander Petrov, 32 years old, Tyumen
It has 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 soil. Naturally, the light tank floated in the spring when the level rose. In such cases, it is necessary to arrange other types, for example, a septic tank of concrete rings or use the useful advice.
Helpful advice! In order not to make a negative review, a septic tank with a seasonal high rise of groundwater should be anchored. To do this, arrange a drain in the pit and lower the slab of reinforced concrete with loops. For these loops tie the capacity with the help of slings. Fill the tank with a mixture of sand and rubble.
“Last year, the septic tank Tank 1 dug in. We live together with my wife and we have enough of this volume. A month ago, children and grandchildren came to visit. There were 8 of us in the house a week. On day 6, everything 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. It is impossible to use a septic tank of lower productivity than required by the standards. This leads to its overload and flooding. In this case, even a breakdown occurred. If you even live together, but you know that you may have frequent guests – buy a device of greater performance.
Most of the negative opinions on the septic tank that are available on the forums are due to a violation of the conditions of its operation or carelessness during the acquisition. Therefore, before purchasing a septic tank, carefully weigh all the circumstances, and when operating, try to follow the manufacturer’s recommendations.
