Important for the private house is a properly created external sewage system, which will further ensure the diversion and purification of sewage. As for the interior, it in many ways resembles a system in urban apartments. It includes all pipelines and plumbing inside the home. The external sewerage network of a private house is a local system containing devices for the treatment of sewage. Recently, external water supply and sewerage networks are arranged in many suburban areas, which allows you to lead a comfortable life.
In any case, the external sewerage of a private house should be well thought out. First of all, it is necessary to determine the place for wastewater disposal. If there is a centralized network nearby, then it is possible to connect the sewage system to it. This will require the permission of the local water utility, which is usually issued after geodetic survey of the site with an external pipeline. In the absence of such a network, a hermetic accumulator or a septic tank with a special filter is most often used. In the first case, it should be taken into account the fact that the car will be driven up by a sewage machine, so the presence of travel is mandatory. The second option is to study the soil and determine the level of occurrence of groundwater.
To date, there are completely different systems of external sewerage, depending on certain conditions. Universality differs from the general sewerage network, which allows to drain domestic and storm sewage simultaneously. However, due to the fact that they pass a lot of water, pipes with a large cross section are required. Sometimes a method is used in which drains are sent to one collector, but through different pipelines. Thus, the load on the pipes is greatly reduced. All of the above methods can be used when there is a tie in the central network. In other cases, separate external sewerage will be appropriate. For this purpose separate collectors with different volume and capacity are made.
Most often for the implementation of installation work , professional builders are involved, but some owners prefer to do all the work themselves. Thanks to this, it is possible to save an impressive amount on wages. First, excavation is performed . The width of the trench depends on the diameter of the sewer pipes. For example, if a pipe with a cross section of 110 mm is supposed to be used, then a pit of 600 mm width will suffice. Depth is determined by the project, based on the features of the site. Next on the sand cushion consistently laid pipes. They are connected with a rubber seal. At the very last stage the trench is filled with soil. As a result, an external sewage system should be obtained, capable of providing high throughput of effluents.
