Among the many diverse types of treatment systems that meet the necessary conditions for sewerage for a cottage or dacha, the most popular today is a simple and reliable device that does not require electricity to operate.
The principle of operation of various septic tanks is the same: entering the septic tank, the wastewater undergoes triple step-by-step filtration, after which it goes into the ground through the infiltrate. The first stage of filtration in the septic tank is the mechanical separation of waste particles into solid and liquid fractions, which can then be purified up to 75% by chemical and biological treatment.
Complete purification of the liquid, which will then comply with Russian norms and SanPiN rules, is carried out using the infiltrate. After that, the purified moisture enters the ground, where it mixes with groundwater. This method is used in many types of septic tanks serving one purpose: ridding the suburban plot of possible contamination by waste and the opportunity to forever forget about the problem of sewerage treatment.
Local treatment systems for country houses and dachas, united under one name - septic tank, work for 25 years without various structural corrections. Their maintenance requires minimal expenses - it is enough to check once a year whether the septic tank is clogged with compressed waste.
Among the many types of drainage systems, the most popular is local drainage, which protects the foundation of buildings built on a suburban plot from destruction. Using a system of drains laid at a depth greater than the bottom of the foundation, groundwater is diverted to a well or natural drain. The specific depth for installing drainage pipes is determined by studying the nature of the soil and the maximum level of groundwater rise in the area.
Drainage of the entire plot is the most relevant method when the plot is located on marshy or heavily waterlogged soil. Such a system will allow confidence in the stability of the soils: having laid drains throughout the plot, it is necessary to discharge and drain the accumulated groundwater into a well located at its lowest point. If the soil is sandy, it is better to arrange a drainage system around the perimeter of the plot: the capacity of the pipes must be sufficient to drain water from it.
In lowlands and marshy areas, stormwater drainage systems are also used, capable of quickly diverting streams of rain or meltwater from the plot.
