What is this device and how does it work? A septic tank is an autonomous treatment plant that is designed for domestic and household wastewater and is the most optimal solution for organizing a local sewerage system. Purification in it takes place by capturing insoluble wastes and organic substances in the first compartment, and their subsequent destruction by anaerobic bacteria in other sectors. The device came to replace obsolete cesspools, which were often used in summer cottages and suburban areas due to their low cost. However, a significant drawback of the pits is the smell that spreads throughout the area and, as a result, unsanitary conditions.
In this case, a septic tank is an eco-friendly alternative. Although this solution will cost more, it will save money in the future, since we are considering devices equipped with a cleaning system. Septic tanks are made from a wide variety of materials. In particular, from brick, plastic, reinforced concrete and metal, there are also combined options. KP presents a selection of the best septic tanks for a private house.

Greenlos Aero 5 PR (low building)
Greenlos Aero is an aeration system, thanks to which it is possible to achieve complete purification of sewage liquid, including industrial effluents. The system is quite popular due to its versatility, and the design provides for a separate sealed compartment, which is not combined with the working chambers. Thanks to this solution, in case of emergency, you can not worry that electrical equipment will be flooded.
An aerator is built into the septic tank, which is designed to force air for the reproduction of aerobic bacteria. This allows you to clean the drains as much as possible. The station is equipped with strong lugs that prevent the equipment from floating up even in flooded areas. With a low body of only 1,2 m, the system can be installed in areas with high groundwater flow, and installation and maintenance is easy for the user.
The Greenlos Aero system is made of high-quality and thick polypropylene, which ensures the durability of the structure. The seams of the station body are made on the machine, which makes the seam more durable. Its cylindrical body is resistant to squeezing and floating, even where groundwater flows high. The station has an additional 5th chamber – a silt sump, which serves to collect dead silt that settles to the bottom. The sludge sump allows you to service the station yourself. The system is thought out, so the need for its maintenance is minimized. In addition, it is certified (ISO 9001 certified) and has successfully passed the safety and quality examination.
The Greenlos line also includes caissons, cellars, wells, sewage pumping stations, pools, etc. All products of the manufacturer can be purchased in installments at 0% for up to 12 months.

How to choose a septic tank for a private house
More recently, residents of country houses used sewage pits for waste disposal. However, with the advent of septic tanks on the market, the situation has changed dramatically. The variety of devices can mislead even an expert on wastewater treatment plants, not to mention a simple consumer. For recommendations on choosing a septic tank, Healthy Food Near Me turned to consultant of the online store “VseInstrumenty.ru” Elvira Makovey.
Popular questions and answers
What parameters should be paid attention first of all?
Septic tanks also differ in the principle of operation. In particular, they are divided into storage tanks, settling tanks and deep cleaning stations. The first are simple in design and minimal functionality. They are used mainly in cottages intended for seasonal living. Sumps purify water by only 75%, it cannot be reused even for technical purposes. Deep cleaning stations, designed not only to accumulate wastewater, but also to purify it for reuse for technical purposes, are ideal for a cottage used for permanent residence, as there is a good opportunity to save on watering the garden.
The choice of device should be based on the following parameters: the number of residents, the type of soil on the site, the area of the site, the depth of groundwater.
Is it possible to install a septic tank with your own hands?
Where will the septic tank be located?
How and who will provide the service?
After that, you can start installation work. You should start by marking the site where the land work will take place. Sand bedding is arranged at the bottom of the pit. The thickness of the sand layer is about 30 centimeters. If the site is damp, then the bottom of the pit is strengthened not only with sand, but also with a concrete slab, on top of which sand is also poured. In any case, no matter how the septic tank is placed in the pit, before installing it, you need to carefully inspect the container for possible damage – cracks, chips, etc. If such are found, they should be repaired before installing the container in the pit.
