To ensure comfortable conditions in a country house, a reliable working sewage system is needed, which only a septic tank can create without pumping. There are no anaerobic processes in such devices, in connection with this, hydrogen sulfide is not formed during operation, which, in turn, leads to absolute safety. These units are quite easy to use. They need to be cleaned only a few times a year. Therefore, a septic tank for giving without pumping becomes the best solution, allowing you to effectively disinfect water. Its application allows to significantly save on electrical energy and pumping.
However, even a septic tank will not be able to completely recycle sewage without pumping, since household waste includes more than one organic matter subject to biological decomposition. Also, the drains contain a number of impurities that do not dissolve in water at all. Therefore, after some time, sediment still remains, accumulating in special chambers. Residues of such impurities sooner or later have to be eliminated. However, this is done much less frequently than pumping out wastewater from a conventional cesspool.
To understand what a septic tank without pumping is, it is necessary to consider the standard principle of operation of deep sewage treatment plants. They include: a supply pipe, a septic chamber, an aerator, a biogenerator, secondary and tertiary clarifiers and a discharge pipe. Although these installations are called autonomous, they require the presence of electrical power for full operation. It is due to the current that the compressors supply air to the aerators. In some units, water is pumped using airlifts, but they also rely heavily on electricity.
When a septic tank works without pumping out, all drains are sent to the receiving chamber, which is usually larger than the others. Its task is to accumulate household waste in the form of a liquid and participate in water clarification. Light impurities like fats and insoluble carbohydrates collect in the upper layers. After a certain time, their structure changes. Thus, the main part under the influence of yeast passes into a soluble form, while the other part precipitates. Impurities that are heavier than water sink to the bottom and fall under anaerobic decomposition. Clarified water is gradually transferred further.
Septic tanks are pumped out once or twice a year. The price of the devices plays a big role in the number of transactions that areyou can actually do it yourself. In extreme cases, for this, there are many services involved in the maintenance of such sewers. At a certain time, specialists will arrive and, using a drainage pump, will empty the contents of the sump. After washing with a special device, the installation is ready for operation again. Of course, the cost of devices that do not require frequent evacuation is much higher than simple sealed containers.
