How to make a sewer in a private house with your own hands

Centralized sewerage in private buildings and holiday villages - a rarity. If you do not want to give up the usual and necessary amenities, you will have to solve the problem of drainage on your own.

You are building a sewer for a long time, so do not try to save on it - these costs are justified.

Septic tank device

I propose consider the device of a septic tank in a private house with your own hands using the example of plastic options, taking into account their parameters and specific conditions. A plastic septic tank is an impermeable tank of two chambers (the easiest option).

Principle of operation

Effluent flows through pipes into the first chamber. Heavy fractions settle, and fat and other impurities float up. There is a primary clarification of water.
Water overflows into the second chamber with bacteria, where settling and purification continues.
Complete wastewater treatment is completed in a biofilter, after which the water is discharged into a filter well or returned to the house for reuse.

How to calculate the volume of stocks

Choosing a septic tank model, consider the volume of drains, since the number of cameras and their capacity depend on this. The chamber must accommodate three-day drains, therefore:

With a daily volume of drains up to 1 cube, one chamber is enough.
A two-chamber septic tank will cope with 10 cubic meters.
For larger volumes, a three-chamber model is required.

Installation and operation of a septic tank

Buying a septic tank You will definitely receive instructions for its installation and operating instructions. Specialized firms, you just need to call them, they will pick up and install. But this is not about us, we will do everything ourselves!

try follow the following recommendations so that the result does not turn out as in the photo :)

1. Preparation of the pit

The dimensions of the pit depend on the parameters of the purchased septic tank model, as well as on the soil on the site. At the bottom, in any case, you need to lay a layer of sand of 150 mm, a foundation or a concrete slab.

2. Installation of a septic tank.

The structure must be carefully lowered to the bottom of the pit and filled with water. After that, sand is poured into the voids on the sides.

3. Post-treatment

If additional treatment is provided for in filtration fields, they should be located at a distance of more than 50 meters from a water source, 30 meters from a reservoir and 5 meters from housing.

4. Pipe laying

At a depth of 50 cm, trenches are dug, the bottom is covered with sand and pipes are laid. A layer of sand and soil is poured on top. When using aeration fields, the trenches must be deeper.

5. Prevention

Maintenance of autonomous sewerage comes down to annual tank cleaning. Installation of obviously high-quality equipment is a prerequisite for a comfortable life in your own home.

If you order the installation of a septic tank to specialists, the installation price will be from 20 to 60 thousand rubles, which means that installing a septic tank with your own hands is a profitable business.
