An increasing number of people tend to be closer to nature and choosing the option between an apartment and a private house chooses the latter. But in order to stay in it was not less comfortable and convenient than in a well-appointed apartment, it is necessary to take care of uninterrupted water supply and drainage.
After all, you will agree that the boardwalk of a street toilet is not the level of comfort that a modern person wants to have. When asked what autonomous sewerage is , the answer is simple: it is any system that does not depend on centralized municipal sewerage and is designed to remove dirty waste water from the premises.
Autonomous sewage systems
Under the concept of an autonomous sewer for a private house, there is a system that drains waste water from the house, accumulates and filters them. There are various in their functionality of the system of autonomous sewerage. Some of the simplest of them can be built independently, and for more complex engineering structures it is necessary to involve specialists in this field, accordingly the costs will be many times greater.
The installation of autonomous sewerage is now being carried out by many construction and specialized firms. Some of them offer turnkey equipment and turnkey installation. In order to simplify the service of the septic tank in the future and not to think about it every month to pump it out, complex multilevel systems for tapping and purifying wastewater are installed. As a rule, all of them require an electrical connection, which in turn increases the cost of electricity, and, accordingly, the payment for it.
The best autonomous sewerage system to date is one that requires pumping out about once a year or does not require at all. Such a result can be obtained by applying drainage or filtration fields, which are the last stage of wastewater treatment and drain the drains into the ground.
The system consists of two or three wells and a filtration field. At the outlet of the room, the drain pipe is connected to the main filtering well, in which fat and insoluble particles settle. Then follows the well, into which polluted waters are poured, and with the help of anaerobic bacteria decay and neutralization of harmful substances occurs. After that, the water enters the filtration fields or filtration blocks, and is gradually absorbed through the drainage holes into the soil.
However, such a system has its drawbacks. It is suitable only if the soil on the site is light, sandy and breathable. If the soil is clayey and the groundwater is high, then this way of draining will not work. Another significant drawback is that the system of drainage wells and filtration fields occupies a large area on the site. Accordingly, all installation work should be carried out during the construction phase and before the site planning.
A similar option, but only without filtration fields, is a triple septic tank with overflow. With this method of cleaning, if drainage wells have a large volume, pumping is very rare - every few years, and this makes life much easier. Wells for such a septic tank are poured from concrete or mounted using reinforced concrete rings, which is times faster than brickwork. The bottom of the last well is laid out
Autonomous sewerage in the house can be arranged and with the help of a large plastic container, designed for several cubic meters (depending on the number of people living in the house). It is installed, the excavation is excavated, and pumped out as it is filled. The main condition is that the special vehicle can access the septic tank.
In all systems it is desirable to use special drugs that break down fats and purify water with the help of bacteria that are populated in a septic tank.
