A septic tank made of concrete rings

In this lesson we will consider the construction of a septic tank of concrete rings, but let's first determine what exactly we need a septic tank for, many will say: "Why do we need a septic tank," then our neighbor made a drain hole and sort of normal( how to make a drainage pit with their own hands), only the sewer machine all the time causes, well, you yourself answered your question a drainage pit - this is certainly a good design, especially if you rarely use sewerage and not so often you are staying at a dacha or in your country house. In the opposite case, you have to pay for the cleaning of your cesspool every month.

Is there really no alternative except septic ask you? There is!- a cesspool of concrete rings, for example. If the bottom is not cast, but the drainage, and the bottom is made of a filter of gravel and sand, the water will go to the ground, namely into the groundwater, but here it is worth noting that the volume of water consumption in this case should be minimal,to such a design simply can not cope with a large volume of sewage, and also without the help of a sewer machine can not do. And finally, you will have the last question, and why use concrete rings and other structures, but simply do not dig a large hole and do not install a sewage system that will never overflow. The answer is simple!.When creating a large diameter drain hole and when using it on a large scale, the soil in your area will quickly clog and pollute the water in your well, and an unpleasant smell will be heard within a 5 meter radius of the drainage pit. So, in order to avoid such difficulties in this article, we will consider how to make a septic tank of concrete rings with our own hands.

Advantages of a septic tank

To finally put an end to questions about the use and rational use of a septic tank, let's put the pros and cons of using it.

1. Keeps clean soil;
2. Protects against unpleasant odors;
3. Do not pollute the groundwater not you do not neighbors.

To the disadvantages of using a septic tank can be attributed only the labor costs for its installation, by the way, if there is no desire to make a septic tank of concrete rings, install a ready-made septic tank TANK.

Make a septic tank of concrete rings

Let's look at the construction of a three-compartment septic tank made of concrete rings. In general, you can see it in the figure above. Matters the question, why use 3 concrete chambers? The answer is simple: the main chamber is the No. 1 chamber, where the plums from the sewerage actually come in; in general, it is a septic tank; in it, the anaerobic movement of wastewater occurs in hermetic conditions. This is the process in which microorganisms multiply and,gases and alkalis that actually break up the waste and turn them into products of almost complete decay, it is for this that sometimes special bacteria are added to the first chamber( septic tank) for septic tanks, which are more intensiveererabatyvayut drains.

In the second channel, aerobic fermentation takes place where bacteria also process water, but with the presence of air taking them out of the water. Thus in the second chamber the bacteria decompose the remaining elements and deposit them on the bottom where they gradually decay.

The third channel receives almost pure water, which already goes to the bottom or to groundwater. Thus, the third well is drainage, that is, in contrast to the first two, the bottom serves as a sort of filter, accordingly it is not cast. Below is a diagram of a septic tank of three concrete rings, it is also worth noting that a septic can also be made from two rings, but then the second ring will be drainage and the water that will go to the soil will be slightly dirtier.

In the figure below you can see in more detail how to install pipes and under what slope, as well as many small details on which usually there are questions related to the construction of a septic tank.

Digging of foundation pits for installation of concrete rings

For each concrete ring, a pit is digging, which in diameter should be larger than the concrete ring by 20-30 cm, that is 1.2-1.3 meters( concrete rings usually have a diameter of 1 meter).Note that there are several ways to install concrete rings, of course the most common way is to install trenches in a single line, but also triangular arrangement of concrete rings is no less often used.

Preliminary, a concrete foundation is poured onto the bottom of the foundation pit, the concrete is not poured onto the bottom of the third ring, because the third well is drainage. With regard to fixing the concrete wheels, the seams are lubricated either with a special sealing lubricant or resin, but at the present time, sealing can be done with the help of modern tools such as sealing joints with a bastion.

We also recommend to watch a thematic video in which you will learn more about installing a septic tank. Install the septic tank in the corner of your summer cottage( so that there are no odors in case of leakage), but note that the laying of the sewer pipe must be carried out according to all rules, that is, it should be about 2 cm per meter long, only then the drain will be goodwork, and if you put the septic tank too far from home, then you will experience some inconvenience in the supply of sewage to the septic tank, because special equipment will be required.

By the way, speaking about the technique in case of incorrect installation of the septic tank, it should be located in the place where the access to the sewerage machine is possible - this is done if your septic tank is overfilled and will not work, there was a possibility of pumping out.
