Septic tank: negative reviews and the reasons for their appearance

Tags:Sewerage, Septic tanks

INThe replacement of cesspools and septic tanks dug in the ground are a thing of the past. In the 21st century, Russian legislation requires private house owners to install plastic or metal septic tanks, in which sewage is separated into water and solid fragments. After such a separation, all fractions are exposed to bacteria that destroy all compounds dangerous to humans. Septic tank negative reviews (in most cases undeserved) about which are posted on the Internet, works according to this principle.

How a septic tank works

This device consists of two separate units - a sump and a biofilter (infiltrator). The sump is made of durable plastic with a thickness of over 10 mm, so it can easily withstand soil pressure. Inside the sump there are 3 sections that connect the overflow holes. When wastewater fills the first section, the water flows through the overflow into the second section. This allows some of the solid fragments to be retained. Then the same operation takes place in the second section. Then in the third. Powder containing special bacteria is poured into the third sedimentation tank, which decompose solid fragments into relatively clean water and sludge settling at the bottom. Periodically, sludge is pumped out of the septic tank using a sewage machine. Then the water enters the biofilter, where additional purification and decomposition of the broken bacteria that pose a danger to humans take place into harmless components. Then the water goes into the soil and is absorbed into the soil.

Where do negative reviews come from?

The septic tank, like any other complex unit, is designed to work under certain conditions. These conditions include:

the volume of sewage;
location;
correct service.

How a septic tank is mounted and works

Sewage volume

When the sewerage volume is exceeded and untreated water flows out through the top of the device. Because of this, the owners of a septic tank post negative reviews on the Internet, because it is easier than being responsible for the wrong choice of the device or its incorrect operation. Each model of a septic tank can only process a certain amount of wastewater, which is written about in the instructions for the device.

Water consumption

Location

For the septic tank to work properly, a certain bias is required from the exit from the house sewer to the biofilter. If the angle is wrong, the owners of the septic tank publish negative reviews, because they do not like the fact that the water does not leave the sewer or comes out through the top of the device. In order for the septic tank to work normally, it is necessary to ensure the bias prescribed in the instructions for the device. Another reason why negative reviews appear on the septic tank is the location of the biofilter in soil with low absorbency. As a result, the water will not go into the soil, but will start to spill over the ground, which will cause dirt and an unpleasant odor.

Approximate dimensions for mounting a septic tank

Useful advice! Do not neglect the requirements specified in the instructions for the device. If you install the device in places with a high level of groundwater, then increase the space for the biofilter at least threefold. If it is not possible to achieve the correct slope, use drainage pumps.

Correct service

If a substance that activates the decomposition of large fragments into sludge has not been added to the septic tank, then the interval between calls to the sewer machine should be less. On a septic tank, negative feedback from owners appears when this rule is violated. In the comments they write that the septic tank does not work well, does not clean, and so on.

Septic Tank and its analogues - comparison

Russian and European enterprises produce a large number of septic tanks similar to this device. They differ in color, cost, volume of processed water. If we compare models of the same class, then there are no significant advantages or disadvantages of septic tanks Tank. After all, the general principle and mechanism of action are the same for them. Nevertheless, negative reviews also appear on the septic tank 3, because people hoped that this device could do the work of septic tanks of a higher performance class. The Tank 3 model can process up to 1200 liters of water per day, that is, it is suitable for a house where 5-7 people live. If you use it in a hostel where 15–20 people live, it is not surprising that it will not be able to cope with its duties.

How to choose a septic tank and not be disappointed

Before buying a septic tank, ask the seller to show you the operating instructions for this device or download it on the Internet. Make sure there is enough space in your area to install the container and biofilter. If there is no such amount of free space, then the device will not work correctly, which will not add to your joy and good mood. Also consider the number of people living in the house. If the number of residents is more than the recommended one, the device may not cope with the volume of water. Make sure a sewer truck can drive up to the septic tank to remove sediment. Consider the soil's ability to absorb water, you may need to install several biofilters. If all this is done, buy and install a unit that will delight you with high-quality water purification.
