Nowadays, it is impossible to imagine a comfortable home without a sewerage system. And this fully applies to country dachas. Many people believe that the process of arranging a sewage system in a private house is quite laborious, but this is not the case. The main condition for creating a sewage system in the house is the correct choice of soil with good drainage properties..
If you do not take into account this rule, then you can face the problem that the cost of cleaning the sewage system will be high, and the desired effect will not be obtained. Before equipping the sewage system in a suburban area, first of all, you should take care of wastewater treatment. For this, in most cases, a septic tank or a cesspool is equipped, which are subsequently connected by means of a drain to the sewerage system of the house..
For these purposes, pipes with a diameter of 10-15 cm are usually used, made of cast iron, asbestos or plastic. The pipes should be laid with a slight slope into the ground to a depth of about two meters. In the process of digging a trench, it is recommended to pay attention to the evenness of its bottom. In this way, deflection of the pipeline during its operation can be avoided. To eliminate irregularities in the places of their presence, a sand pillow is made.
In addition, you should take into account the location of the floors in the house relative to the upper level of groundwater. If they are located at the same level, there is a high probability that, if the sewage system is clogged, sewage may end up directly in the house, since the law of physics about communicating vessels will work. This problem can be avoided by installing a valve on the pipeline..
If there is no centralized sewerage system on the territory of the land plot, and the equipment of a septic tank is not possible, then the best solution to the problem of drainage from sewage is to equip a cesspool. In this case, it should be located at a distance of at least 25 meters from a residential building, and its depth should be less than the depth of groundwater. Usually this figure is more than one and a half meters. To ensure the tightness of such a structure, the technology of manufacturing a cement or clay castle is used. For these purposes, you can also use wood, stone or brick..
