Landscaping a country house or cottage, you should definitely take care of the availability of utilities. For this, it is not necessary to resort to the services of specialized companies and pay significant amounts for their work. Do-it-yourself autonomous sewage can significantly reduce the cost of construction and repair work. As a result, having invested a minimum of funds, you will receive a comfortable and cozy country house suitable for year-round use.
Do-it-yourself autonomous sewage can be arranged in various ways. In all cases, wastewater flows from the house, passes through a local treatment plant, where it is treated to the required level. Then they are dumped into a ditch or into the nearest body of water.
The most difficult thing is to install exactly the treatment plant. It is worth noting that it can be of two types:
- the simplest are septic tanks;
- more complex - installations of deep biological treatment.
In a septic tank, dirt is separated from the liquid by gravity and settles down. After which the precipitate formed begins to decay in the absence of oxygen. Such devices are quite simple and cheap. Work without additional energy. They can be used when a sewerage system is installed in the country. However, with their help it is difficult to achieve a high degree of purification. They require a large amount of preparatory work. The place of their position largely determines the level of groundwater. You will have to familiarize yourself with a significant amount of information in order to do everything as it should. In addition, periodic replacement of the filter load and the implementation of treatment measures are required.
Deep biological treatment plants can have various designs, which are largely determined by the manufacturer. They can consist of a different number of sections, but the degree of sewage treatment in any case will be quite high. Such an autonomous sewer for the home would be the best option. It allows not only mechanical wastewater treatment, as in the previous version, but also biological decontamination. But in order to choose one or another model, one must initially at least approximately imagine how much water a given installation will have to clean. As a rule, many sellers recommend starting from the number of people living in the house.
Such devices most often occupy a small space, and therefore you do not have to look for a special place for the installation of a treatment plant. Pay for this equipment will have a little more than in the first case. Also, for its operation, an electric current is required. But then such an autonomous sewage system with their own hands will be installed with less physical cost. And for subsequent cleaning in its design provides a special pump, which will be enough to use only a few times a year. The resulting waste will be an excellent fertilizer for plants grown in the adjacent area.
Do-it-yourself self-contained drainage is mounted as follows:
- First, a pit is digging in which the treatment device will be installed, and sewer pipes are brought. Moreover, this is done at a depth below the level of soil freezing in winter;
- then the formwork is carried out, in order to concrete the walls of the pit, the corresponding work is performed;
- a cleaning device is installed;
- a cover is mounted that is similar in type to a suspended ceiling made of a metal corner and slate panels;
- the hatch frame is installed and the brick is laid;
- expanded clay and clay backfill;
- a hatch and waterproofing are arranged.
