The principle of operation of a septic tank
Two-chamber septic tanks work according to the following principle. Through sewer pipes coming from the house, wastewater enters the first chamber of the septic tank, located underground. The receiving chamber collects and mechanically precipitates the incoming waste, whileit contains a special damper, which ensures the absence of agitation of waste. Settling substances accumulate in the compartment of the first chamber intended for this purpose, and the resulting gases are discharged through the sewer ventilation of the system. The second is the filtration chamber. The mesh and sorption filters located in it purify the incoming waste in two stages, finally removing contaminants. From this chamber, purified water flows through pipes for further purification. The water obtained after such purification meets the requirements of sanitary standards.
At the same time, if the septic tank "Rostok" cottage is understaffed with a special post-treatment filter (drainage well), then the quality of cleaning will be about 95%. If such a filter is not used, then the wastewater will be cleaned by 80%.

For pipes, the depth of their laying is taken into account - about 1-1.5 meters. The bottom of the pit is sprinkled with crushed stone and sand and a concrete screed is made, to which the septic tank is attached.
These conditions cannot be neglected, because even if the groundwater does not bother you at the time of installing the septic tank, they can appear at any time and you will have a hard time. In order for the septic tank chamber to be securely and firmly fixed in the pit, when backfilling, it is necessary to periodically fill it with water and tamp the poured layers.

The installation of the "Rostok" septic tank is completed by backfilling the installation site with a layer of ordinary earth in order to hide all traces of the work done and sow grass and flowers.
Installation of filters or a drainage well for additional purification of water increases the quality of purification up to 95%. Biofilters are more expensive and require periodicreplacements.
