The principle and scheme of the septic tank "Tank" + installation and installation of this septic tank do it yourself

Long gone are the days when a sewage system in private households meant a hole dug in the ground into which sewage was discharged. No, of course, such options can still be found in principle, but they are actively being supplanted by new environmentally friendly sewer systems. Installation of a septic tank is one of the important stages in the construction of a modern sewage system. Why exactly this septic tank? Everything is very simple: just this equipment is now at the peak of popularity among consumers. So, it will not be superfluous to once again analyze its strengths and weaknesses. So, the septic tank is a sewage treatment plant ...

Naturally, before choosing, and even more so installing the treatment equipment, it is necessary to understand how the septic tank works.

So, the functional diagram implies the following steps:

• Through the inlet pipe, sewage flows into the 1st chamber, which serves as a sump.
• Large-scale waste is separated in the form of a precipitate, and relatively purified water is transported to the next chamber through an overflow device.
• The second stage of purification involves the decomposition of organic components by using special bacteria.
• The last stage is the transmission of water through the biofilter, while the purification of effluents reaches 75%.
• Finally, the effluents are cleaned in the infiltrator.

More about the infiltrator - the feasibility of installation

In this form, the septic tank (complete with infiltrator) will be mounted in the pit

Properly installed do-it-yourself septic tank Tank necessarily includes an infiltrator. This is a tank without a bottom installed in a pre-prepared foundation pit on a specially arranged high pillow made of high-quality crushed stone. Purified by 75% water when it enters the infiltrator passes through the gravel pillow. At the same time, it is finally cleaned of residual impurities and penetrates the soil. In other words, an infiltrator is a soil filter that provides the ultimate purification of water.

What does the trading network offer?

If you plan to install the Tank septic tank yourself, then first you must choose the model that will be relevant specifically for your sewer design.

On sale are septic tanks of various capacities. And it is the overall dimensions that are one of the determining factors when choosing a treatment equipment. The capacity value is selected in accordance with the estimated water flow, and this indicator, in turn, depends on the number of permanent residents in the house.

Performance Chart

Important! Any of the Triton septic tank models listed in the table must be additionally equipped with the Triton 400 infiltrate. The extension necks (the number is determined by the number of chambers) as well as the lid also belong to the additional equipment.

Self-installation of equipment - as easy as shelling pears

First the septic tank is mounted

The installation scheme of the septic tank is created by the following algorithm:

• The installation case is inspected for any damage. This procedure must be followed necessarily, as it will provide confidence in the uninterrupted and effective use of the septic tank.
• The second stage is land work, that is, a foundation pit is being prepared for a septic tank, while its overall dimensions should be larger than the dimensions of the installation.

Attention! The pit in lateral parameters should exceed the dimensions of the septic tank by 20-30 cm. A sand cushion is also made along the bottom of the pit with a height of 20-30 cm. If, however, a high occurrence of groundwater is found at the installation site, then a concrete slab is laid on top of the sand cushion.

Sand is poured at the bottom of the pit - a pillow 20-30 cm thick

• The next stage is a trench for laying a sewer pipeline: house - septic tank, septic tank - infiltrator. At the same time, one should not forget about the slope at the rate of 2 cm per 1 m of the laid pipeline. This will ensure the transport of fluid by gravity.
• The septic tank is lowered into the pit: it can be done manually, calling friends for help, or it is possible using lifting equipment. What is important is to make sure that all distortions are eliminated.
• If the groundwater is high, then the septic tank must be secured to slabs or nylon straps to a pre-arranged plate. Thus, the septic tank will be prevented from rising when groundwater rises.
• The pipes are laid and then connected to the septic tank.
• To fill the pit, a mixture of coarse sand and cement is used at a ratio of 5: 1. 20 cm high layers are poured and carefully tamped. Each subsequent one is arranged in the same way.
• In parallel with backfilling, the septic tank is filled with water. In the process, you need to control the water level - it must exceed the level of backfill by 20 cm. You can not use special equipment in the process of backfilling, this is fraught with damage - it has been tested many times in practice.

Important! Even at the installation stage, it is worth thinking about how the tank septic tank will be serviced. No need to plant trees around it - the roots can damage the system. The minimum distance at which large green spaces are allowed to be planted is 3 m. It is also necessary to exclude the passage of vehicles at the site of the septic tank.

Infiltrator device

• Retreating from the septic tank 1-1.5 m, digging a rectangular pit.
• The bottom is covered with geotextiles.
• From crushed stone, a pillow is made at least 40 cm high.
• The infiltrator is mounted.
• The pipe is connected: a septic tank - an infiltrator.
• A vent riser is installed at the entrance.
• Sand is used to backfill to the top cover.

Do not be scared!

We tried to disclose the installation topic for you as much as possible and more accessible. In principle, in practice, the production of works looks simpler and, if desired, all the described work can be performed without outside help. In conclusion, you are traditionally offered a video instruction for installing a tank septic tank which shows a solution to the problem with spring floods.
