Modern sewage system in a private house is a system of pipes, risers and a turn that collect and direct drains to the sumps, where they are cleaned, disinfected and merged into the ground. Or they simply defend and assessed as they are filled.
Sewage construction: basic concepts
Autonomous systems that do not require assignization are used in individual housing construction. For this, deep cleaning stations or overflowing systems are equipped, which purify wastewater to a state suitable for irrigation or household needs.
The sewer system of a private house consists of two subsystems – it is actually an economic household and storm sewer. The latter allows you to collect and redirect rainwater, not allowing it to flood the basement or stay in the yard with a big puddle. Such systems have both external and internal contours. All of them lead to a sump or a water bribe for further disposal.
The outer circuit consists of a pipeline, pumps, treatment filters and wells. Its system is septic tanks and drain pits, t. e. Local treatment facilities.
The internal circuit consists of a pipeline and plumbing equipment that removes drains into the external circuit circuit circuit linked.
The internal sewer system is designed depending on the volume of effluents, which depends on the number of residents of the house and its number of storeys. With a one -story structure, “wet” rooms are advisable to have closer to each other. If there are several floors in the house, then one line, this will allow you to reduce all the pipes in one riser.
The type of external sewage system takes into account the quality of the soil of the site: the height of groundwater and soil type. Most often, drain pits, filtering wells and septic tanks are equipped to collect drains.
Drilling pit – the simplest solution to the issue. However, it can be equipped only on strong soils and should often be cleaned, for which to have a convenient entrance. And the smell that accompanies its existence does not add pluses to it.
Filter wells are a more complex construction in the engineering plan. Their arrangement is possible on well -permeable, sandy soils. At the same time, they will still have to be cleaned.
Septics are hermetic tanks where the drains are cleaned biologically or chemically. The resulting water can be used for watering or technical needs. Such a tank can be installed on any type of soil, you can not even deepen it. This is one of the best options today.
Construction of sewers in a private house: some tips
This type of work is clearly regulated by both SNiPs and sanitary standards. Having decided to equip the autonomous sewage system, you must choose its type based on the conditions of the site, and safety requirements.
According to the rules, the minimum distance to the cesspool from the walls of the house is 5 m. For high -quality assignization, the entrances of technology should be organized. The general rule of designing both external and internal systems is its simplicity. The fewer connections and bends, the higher the tightness and longer the life of your sewage.
The design documentation for the installation of the sewer system includes not only the scheduled scheme of all components and a turning, indicating the sizes of the pipes, but also a specific scheme of their location. Including the location of the drain wells and sumps.
During the construction of an external sewer network, it is necessary to remember the insulation of pipes, especially those that pass at a small depth. Furious sewage system – the second after depressurization of the scourge of any sewage system.
