The device of a septic tank from concrete rings

Planning of Septic Sewerage Systems

Let's consider some specific actions with which you can erect septic tanks made of concrete:

1. The scheme of cleaning the drain on the ground plan is applied.
2. A plan should be drawn up with a list of materials that will be needed in the further installation of concrete rings.
3. Bringing all materials to the site.
4. Preparation of all operating equipment.
5. According to the plan, it is necessary to conduct all land works.
6. Installation of all necessary components.
7. It is necessary to produce heat and waterproofing works with a concrete sump.

At the beginning of the installation, it is necessary to understand the principles of the installation. Most often, the sump consists of 2-3 wells, which must have a connection to the overflow line. How correctly wastewater should flow when there is a septic device from concrete rings, for example:

• Dirty water enters the first container, in which processes of gravitational decomposition into fractions occur. Further, water enters the second container, when the decomposable process of all organic components is flowing in the first well, with the aid of which, all bad and harmful chemical activities are reduced.
• The next container, that is, the second, is completely analogous to the first tank.
• The third well differs from the first two with its permeable bottom. Through this bottom, all the effluent that has passed through the treatment is absorbed into the ground.

Planning of septic water treatment systems

Before starting the installation work, it is worth paying attention to preparatory work, such as:

1. It is necessary to maintain a certain distance from your facility, to a sump that must be at least 5 meters. A well with clean water at a distance of 30 meters.
   

   For all installation work and preparation, it is advisable not to forget about leaving the place for the arrival of the sewage machines, since they are the ones who are cleaning your installation wells. If you do not want to do everything twice, you need to remember about this moment.

2. The most important thing for the initial stages in the procurement of materials is the purchase of reinforced concrete structures. You can absolutely compute the calculation and find out how many rings are needed. You can buy a lower view of the wells with a flooded bottom, but they are very heavy for movement. The upper part can be easily replaced by shield-type structures.
3. You can also use materials like:
   • Plastic pipes.
   • Tees.
   • Asbestos pipes are used for ventilation systems.
   • Building mixtures.
   • Bituminous materials.
   • Required Tools.

In order for the septic device of concrete rings to work well, it is necessary to carry out the installation work:

1. The first step is to excavate the excavation. Its joints should be covered with insulation, for this it is necessary to dig the width of the excavation with a small margin.
2. Installation work, which should be performed as follows:
   • Setting of the horizontal slab in the excavated trench.
   • The first ring is set on the slab, which consists of concrete.
   • Then the remaining rings are installed, which are waterproofed.
   • Two holes must be made on the last ring. To do this, you can use a punch.
   • It is absolutely necessary to cover the sump with a hatch or material that can be lifted while servicing.

   It is important to remember that in no case should the concrete rings roll on the ground when carrying, they only need to be carried and placed gently on the ground. It is also desirable to carry out all procedures associated with spreading with waterproofing agents or heated bitumen on the surface, so that the groundwater does not interfere with the runoff.

3. The third well also has the same installation, if it is included in the project.
4. The design of the third well is absolutely the same as the first two, but with its small differences. The first is that the ring is located at the bottom of the hole already with the holes made, for a good run-off. The second is that the inside should be covered with gravel or claydite, and the surface with piercing stones. And the last thing is that the circle of the ring should be filled with claydite or gravel, for better filtration.
5. Connection of pipes with a slope of the drainage system to the sump.
6. We make a waterproofing layer, it is possible to use thermal insulation under cold climatic conditions.
7. Establish ventilation. It should include an outflow and supply pipe. The outflow pipe should have its location above the second, for better traction.
