How to use concrete rings for sewage

If you visit a country house or a cottage from time to time, you may not even want to install a sewer system at the site. Otherwise, it will help you to bring the level of comfort closer to an ordinary city apartment. This article will be devoted to the second option, where the main role will play concrete rings for sewage.

Why concrete rings

In addition to the usual description of the sewage system itself, the positive and negative sides of this project will be affected, and we will also touch upon the installation of the structure. Why exactly this design interested us, but not modern plastic rings?

Most likely due to:

• simplicity and reliability of such septic tanks;
• simple installation of rings;
• affordable prevention and repair facilities;
• low cost kit.

Kinds

As a structural element, concrete rings differ from each other, although if you are not an expert in this matter it will be difficult for you to distinguish them (see also the article Reinforced concrete rings for sewage: selection and use of prefabricated parts).

At this time, manufacturers produce two main types of similar products:

1. Straight lines
2. With a lock".

In the first case, the rings are interconnected by a concrete solution and metal brackets. In the second - they are inserted into each other because of the samples in the upper and lower parts of products.

The latter option is considered much more reliable, since the displacement of the rings in this case is almost impossible, however, their price is higher.

Now consider how they are better products from other materials:

• strong;
• durable (up to 25 years);
• frost-resistant;
• not afraid of water, acids and alkalis.

The standard diameter varies between 720-2000 mm, and the cost of concrete rings for sewage depends on their size, by the way, O1 m products most often buy. Although developers consider that the larger this parameter is, the better the sewage collection will work less often it should be cleaned, but this promise is not always true.

The main parameter is the volume of daily flows. And also, the less often the septic tank will be cleared of sediment, the more it will remain at the bottom.

Because of this, he subsequently turn into a solid substance, for which you will need to use a jackhammer. At the bottom you get a natural stub, because of which the natural filtering through it stops.

We do a septic tank

We hope you understand that with the help of concrete rings you can make a cesspool or septic tank on your site. The process in practice is not as difficult as it may seem at first, so many homeowners make it with their own hands.

Schematically it can be said like this - the tank should be dug into the ground, we think that you can cope with these.

Our task is to tell you about the rules that will allow to carry out the work with minimal cost. You will only have to strictly follow all the steps and requirements for installing rings.

Manufacturers today offer two design options:

Tip: if the relief of the suburban area allows, use a stepwise installation of tanks, when the next below the previous one.

It is this approach to the treatment of effluent that makes it possible at the exit from the third well to receive water, which can safely water the garden.

This happens because:

• the first well is sealed to the maximum so that anaerobic fermentation of sewage occurs in it;
• in the second, the purified water passes through an aerobic fermentation stage, as a result of which sewage residues decompose under the action of bacteria and precipitate;
• the third septic tank is a drainage one, through the bottom of which the purified liquid is again filtered and enters the ground.

Assembly process

Before you understand how to make a sewage with your own hands from concrete rings, you need to know that the septic tank can not be installed close to the apartment building. Smells will still pass through all sorts of gaps and cracks, although this is a sealed design. In addition, excavation work near the foundation will also not benefit the latter.

Tip: select the lowest point in the area, preferably in the corner.

Also note that the sewer pipe must be installed at a certain angle (20 mm per 1 m) so that the drains flow into the septic tank by gravity. Therefore, the further the structure is installed, the deeper it is necessary to bury it.

Tip: sewer pipe must be placed at a depth below the freezing ground or insulate it.

Below is a brief process instruction:

1. Usually for a waste well use 2 w / b rings O1 m. They are mounted on each other by a crane or independently using a tunnel. In the first case, a hole is immediately pulled out, in the second case - the shrinkage of the rings occurs gradually.

1. Make a concrete pad at the bottom of the pit, trimming it from the inside with a clay mortar that resembles a blind area to protect the concrete from water.
2. The joints between the rings should be cemented, and then treated with resin.

Tip: treat the external surface of the well with hot bitumen, which will help to extend its life.

1. Lay the sewer pipe between the septic tanks, insulate it and insulate it.
2. Install the cover, fill the soil between the walls of the pit and the collection.

Conclusion

Concrete rings for a sewer well can have a lock or not, and their cost depends on the size of the finished product. Installation of a septic tank can be carried out using a truck crane or a digging method. In the manufacture of a multi-chamber septic tank, it is necessary to properly install the drain pipes between the decks.
