How is the sewage system in a private house, the scheme of which would satisfy all modern norms and requirements? It is no secret that suburban developers are trying to use technologies that at least a little saved the budget allocated for construction.
How to make a sewer in the house – materials and nuances

How does the process begin? With design. First of all, it is necessary to install the lowest place on the site. For what? Immediately make a reservation that the most economical sewage of a private country house with your own hands is a gravity. Therefore, from the house to the collection of effluents will have to lay the pipe at a certain angle. And in order for the conduct to be easy, you need to install the well in the lowest place, this will reduce the volume of earthwork.
After that, it is necessary to draw a straight line to the house, which will determine the future route. Everything is ready, you can start earthwork.
Excavation

If possible, and the track is quite long, then you can use the services of an excavator. This is the time of work, but will increase their cost. After all, the price for special equipment services is expensive. If you decide to save, then all excavation work will have to be carried out manually using proven tools: Kirka and shovel. In order for the work to go quickly, it is recommended to dig on both sides: some begin to dig a hole under the septic tank, others – trenches from the house. This is an addition to the question of how to properly lay the sewer.
Please note that the depth of sewage laying in a private house depends on the level of freezing of the soil.
If the freezing level has a fairly large indicator, for example, 1.5-2.0 meters, then do not go deeper so deeply. You are just tormented by tearing off both the hole and the trenches. You can lay the route closer to the surface of the earth, but the pipeline will have to thermal insulation. In principle, these are small financial expenses, but you can win in time.
And another very important point that concerns the angle of inclination of the sewer system. Optimal – in the range two to three centimeters per meter of the track length. If you make an angle less than two centimeters, then the drains on the pipe may not go through, especially for large fractions of sewage. If the angle will be larger, then the liquids will skip at high speed, and the suspended particles of any fractions will remain inside the sewer. Therefore, taking off the trench under the pipeline, you must immediately observe the slope. By the way, if the sewage circuit in a private house has a straight area, then the angle of inclination can be 2 cm, if there are turns, it is better to take a parameter of 3 cm.
Now about the septic tank, or rather, about the pit for it. It must be torn off depending on which collection it was decided to establish. If it is reinforced concrete rings, then five rings with sizes will be required to create a normal septic tank:
Diameter 1.0 meters;
Height 0.9 meters.
It will be a five -kubovaya container, which is ideal for a normal country house. There is another option – this is a ready -made plastic septic tank. Here you can choose both in design, and in size, and in volume. It is the shape of the plastic septic tank that will determine the shape and size of the pit for it.
Pipes and septic tank for sewage in a private house
Before you conduct a sewer to a private house, you need to take care of the septic tank. If the finished version was purchased, then everything is simplified to a minimum. For this, the bottom of the pit is aligned, compacted and poured with sand. A plastic septic tank has a slight weight, so two or three people will be able to raise it. So, to let it go into the pit and put it out will not be difficult. The only nuance – the input pipe of the container should be oriented on the trench.
Now you can install sewer pipes. Choose plastic pipes, they are cheaper, more practical, easier, do not amenable to corrosion, they gather quickly. Pipe connection is carried out using plastic couplings. But before laying the trench, you will have to sprinkle with sand, and check the angle of inclination again.
After that, the pipes are put at the place of their appointments, the slope is necessarily checked. If the slope is wrong in some place, then the sand must be poured under the pipeline or, vice versa, remove it. The connection of the septic tank and the pipes, as well as the internal and external systems, is carried out using the same couplings. But on this, the sewage wiring in a private house may not end. Sometimes you need to install a pair of observation wells for servicing pipes and cleaning them.
Now you can fill the track with a small layer of sand, and on top of the ground. The gap between the septic tank and the walls of the pit is best filled with sand. But even in this process there is a small nuance. Falling asleep, it is necessary to fill the plastic tank with water. This is done so that the sand does not bite the walls of the septic tank inside. The upper part of the septic tank is camouflaged, that is, it is made inconspicuous. It is covered with soil, plants are planted, flowers.
For those who, after reading the article, do not delve into how the sewage system is done in a private house with their own hands – a video with a description of the process is on our resource.
