The convenience of living in a country house or in a country house is highly dependent on the availability of a sewer system. If it is impossible to connect to the sewer network, it is recommended to install a local treatment plant for a summer residence, where domestic wastewater will be collected and processed. The EcoTechAvangard company designs and manufactures modern, economical to install and efficient sewerage systems for cottages. Our product range includes aeration stations that provide deep biological wastewater treatment, and autonomous sewers for private households.
Purification system functions
Objects of this type perform 2 basic functions: collection of domestic wastewater and their further treatment in order to prepare for disposal in a natural way. In our systems, cleaning is carried out by a biochemical method in several stages.
Mechanical. Large fractions and undissolved impurities are retained in the treatment plant for giving.
biological. Aerobic / anaerobic mechanisms process complex substances into simpler ones suitable for further utilization. Complete processing of organic inclusions, including nitrogenous ones, is carried out.
Physico-chemical. Such cleaning consists in getting rid of suspensions and dissolved impurities.
Equipment for wastewater treatment plants
The package of treatment facilities for the home may include diverse equipment: pumps, filters and biological treatment complexes, compressors, controls, etc. The final list depends on the type of sewer installation and customer requirements. In general, the equipment can be divided into treatment (various traps, filters, etc.); functional (ensures the operation of the structure - for example, pumps organize the supply of wastewater); drainage. Also, modern stations are equipped with controls.
Operating principle
Our systems use biochemical wastewater treatment with activated sludge. Organic pollution is processed by accumulations of aerobic (requiring oxygen) bacteria. Conventionally, the process taking place in a treatment plant for the home can be divided into two stages.
biological maturation. At this stage, in the aerotank, subject to the supply of oxygen, the optimal amount of active sludge (sludge) is built up, which depends on the volume and chemical composition of the effluents, and the operating mode of the installation.
Stationary biochemical oxidation. First, the biosorption of organic inclusions by activated sludge flakes occurs, as a result of which the amount of pollution decreases sharply. Then decarbonization and further decomposition of organics are started with the involvement of more complex biochemical reactions.
Further wastewater treatment consists in their nitrification. This is the decomposition of nitrogen-containing substances. Thus, treatment facilities for the home provide multi-level wastewater treatment.
Types of treatment facilities
Septic tanks. They are tanks made of metal, plastic, concrete. The number of cameras may vary. Conventional storage septic tanks have one compartment where wastewater accumulates. The latter are not cleared. More advanced treatment facilities for giving include several departments, in each of which a certain type of cleaning is carried out.
Aerotanks. They provide a constant flow of wastewater. Throughout the volume of the aerotank, aerobic bacteria are actively working, which decompose the contaminants present in the wastewater. Usually, effluents are fed into the aerotank after undergoing mechanical treatment. It should be borne in mind that this type of treatment plant for giving provides for mandatory equipment with aerators that force air into the system.
Bionic system. Unlike septic tanks, it does not require the mandatory arrangement of filtration fields. The Bionic system compares favorably with aerotanks in that, in the absence of electricity, it turns into a conventional septic tank, maintaining its performance until the electrics are turned on.
Architectural and construction execution
Semi-embedded or buried. The cleaning system for giving is fully or partially dug into the ground. Such stations are compact in size and operate completely autonomously. They do not spoil the view of the site. However, their basic drawback is the need to perform earthworks. It should also provide access to the equipment. Usually this option is equipped at the stage of building a house.
In a building made of light metal structures. If the site area allows, the cottage sewerage system is located in a separate building. Usually it is assembled from light metal structures. This method of organizing local sewerage is good because it does not require earthworks and is performed quickly enough. Free access to the equipment for the purpose of repair/maintenance is provided. The downside is the need to allocate special areas for the system.
Container version. With this installation option, the system is a single container, where all the necessary elements and assemblies are collected. This option is convenient due to its compact size. Installation is faster and easier than with other options for organizing local sewerage. The disadvantage is the complexity of repair and maintenance, because in the event of a failure of a certain element, the entire structure will have to be opened.
What to consider when choosing
When choosing a sewer for a cottage, it is necessary to take into account, first of all, the average daily volume of effluents. According to the current SNiP, it is 200 liters per person. Individual characteristics are also important, for example, the volume of the bath, the number of water use points, the number of wastewater discharged into the installation at a time. The next important parameter is the types of pollution. It is necessary to take into account the varieties of disinfectants and cleaning products used in everyday life, the need to ensure grease removal and disinfection of effluents. The third point is the features of the architecture of the building and the relief of the site. It is necessary to determine how the purified water will be disposed of - by gravity or through forced release. The depth of laying the sewer pipe, the height of the rise of soil water, the level of freezing, and the relief of the site matter.
For many summer cottages have become a place of permanent residence in the summer. But in order to make life in the country more comfortable, it is necessary to equip the site with all the benefits of modern civilization. One of these “achievements” is sewerage. But in this case, there is a problem with wastewater treatment. In this article we will tell you how you can make a sewage treatment plant for a summer residence with your own hands.
Cesspool
The easiest way would be to install a cesspool. As a rule, such structures are made without a sealed bottom. As a result, all liquid effluents seep into the ground, and solid waste accumulates in the pit. Then they can be processed using biological products or pumped out using a sewage machine.
Such cesspools are very popular in rural areas. But such facilities can hardly be called treatment facilities. In fact, all effluents end up in the ground and can harm the environment. In addition, according to existing sanitary and hygienic rules, the cesspool must be completely sealed.
For a summer cottage, where people rarely visit, such a structure can still be used, but if they live here permanently (even only during the warm period), then it is better to make a septic tank.
Barrel septic tank
A septic tank is a more modern sewage treatment device. Today, a variety of models are on sale. Their installation will help to produce almost one hundred percent cleaning. But still they cost money and sometimes a lot, so many craftsmen build septic tanks on their own. For example, a barrel device is perfect for a summer cottage. How to make such a septic tank, we will now tell.
First you need to prepare the necessary materials:
- two plastic barrels with a volume of 250 liters. It is better not to use metal ones, as they are highly susceptible to corrosion;
- geotextile;
- plastic sewer pipes with a diameter of 110 mm;
- drainage pipe;
- fittings for connection;
- gravel and sand.
You can start making a septic tank:
- The first step is to dig a pit and trenches for laying pipes. The pit for the septic tank should be 20-30 cm larger than the barrel in each direction. The depth must be done in such a way that the top of the barrel is below the freezing level of the soil, and for the second barrel the bottom needs to be somewhat deepened to ensure a slope.
- At the bottom of the pit, after careful tamping, a pillow of sand or crushed stone with a thickness of at least 10 cm is laid. Fastenings must be made at the bottom to hold the barrels. Otherwise, in the spring, groundwater can push out empty barrels.
- Now let's prepare the barrels themselves. To do this, in the first one, which will play the role of camera No. 1, we cut out two holes. One on the lid, the second on the side at a distance of 20 cm from the top edge. There will be three holes in the second barrel. One is also on top, the other two are on the sides (through them the water will flow to the filtration fields). The diameter of all holes must be 110 mm.
- Now it's time for assembly. We lower both barrels into the pit and make their connection. The pipe from the house should enter the top hole of the first barrel. From the side opening of chamber No. 1, the pipe passes into the top cover of the second barrel. From the side openings of chamber No. 2 we divert two pipes to the filtration fields. All connections must be sealed.
- Before starting backfilling, it is necessary to fill the septic tank with water. At the same time, you can check the tightness of the connections. The backfill is made from a sand-gravel mixture, in layers with tamping.
- Above the first barrel, it is necessary to make a manhole and ventilation. This is necessary to clean the chamber from accumulated solid precipitation.
- Two pipes from the second barrel should enter the post-treatment fields. For them, a foundation pit is also dug, on the bottom of which geotextiles and a layer of rubble are laid. Then pipes with pre-drilled holes are laid, and everything is covered with another layer of rubble.
The resulting septic tank from plastic barrels does an excellent job of cleaning drains from a country house. It is designed for a small amount of sewage. If a lot of people live in the house constantly and all year round, then such a septic tank may not be able to cope with its tasks.
Septic tank from improvised materials
It is possible to build a septic tank for a cottage from other materials. For this use:
- old car tires;
- concrete rings;
- brickwork, for example, from old bricks;
- concrete structures, etc.
All of these methods are inexpensive. Also, the low cost of all work contributes to the small amount of effluents at their summer cottage. People don’t come here so often, only on weekends, so it makes no sense to make large containers.
Whatever material is used, the main thing is to follow some principles. Namely:
- The septic tank must consist of at least two chambers, the first of which must be airtight.
- It is necessary to periodically pump out the accumulated sewage from the first tank.
- It is advisable to use post-treatment fields.
The best wastewater treatment occurs when using biological products with live microorganisms.

Unable to connect to the central sewer? You can solve the problem locally - install a septic tank. To make this task easier, we have prepared a review of 9 reliable septic tank manufacturers. Chances are good that other companies you come across are either copying or counterfeiting these 9 products.
We warn you! Here and below, by septic tanks, we mean any engineering structures designed to collect or process wastewater, unless otherwise indicated. Including these are VOCs and SBOs - local treatment facilities and biological treatment plants, respectively.
Instructions for the selection and installation of VOC
Purpose of the article: tell about the most reliable companies that have been producing septic tanks and biological treatment plants for domestic wastewater for more than 10 years. Simplify the selection of a suitable equipment model based on the needs of the buyer, the soil conditions on the site and the budget of the purchase.
Types of septic tanks
Before we talk about wastewater treatment plants, let's conduct a small educational program. Conventionally, all treatment facilities can be divided into 3 groups:
- storage tanks. It doesn’t matter what they are made of, their function is the same - to accumulate drains in themselves before the arrival of a sewage truck. Relatively cheap, easy to install, no maintenance per se. Use is limited by the useful volume of the tank, hence the need for economical use of water and binding to the services of sewers. It's inconvenient and expensive. They are used only when soil and other conditions do not allow the installation of structures from the following two groups;
- settling tanks. Multi-section tanks that do not require electricity connection for sedimentation of wastewater and their anaerobic treatment. Microbiological purification processes proceed slowly in an environment depleted of oxygen. The outlet water has a characteristic odor and is purified by a maximum of 60%, so it must be cleaned up. For this, fields or filtration wells are used: effluents seep through the soil layer, after which they do not pose a threat to the environment. Settlers are simply arranged and affordable, but demanding to maintain. They periodically need to be cleaned of accumulated sediment, once every 5 years the filtration field must be redone. This solution is not suitable for high groundwater levels (GWL) and soil with poor throughput, such as clay;
- aeration stations. The most advanced systems for the preparation of households. drains. In the process of sedimentation, aeration and the use of microorganisms, wastewater is cleaned by more than 90%, has no smell, and can be drained into roadside ditches. However, such stations require connection to the mains, their efficiency suffers during power outages. Plus, they are expensive and require qualified maintenance.
We figured out the types of treatment facilities. It remains to take 5 steps to choose the right one for your operating conditions.

FAQ
Here we have collected answers to current questions about septic tanks.
What material is the best septic tank?
Factory products for individual use are made of polymeric materials: polypropylene, low-pressure polyethylene (HDPE), fiberglass. They are relatively light, not subject to corrosion, strong, sealed and durable - all these materials are good.
The only question is to what extent their capabilities are implemented in a particular septic tank design. For example, there may be a container made of polypropylene, in which the seams are poorly welded, respectively, after some time it will leak.
The rigidity of the structure is influenced by the thickness of the material and the presence of structural elements: stiffeners and internal partitions. Therefore, if the design is unsuccessful or simply does not fit the specific operating conditions, the septic tank can be flattened or torn apart by soil. But the point here is not in the quality of the material from which it is made, but in the design itself.
I can not decide between a non-volatile septic tank and a biological treatment plant with aerators. What's better?
If for a summer residence, choose a non-volatile sump, provided that the groundwater level is below 1.5 meters, and the soil itself has good filtering abilities. For example, it is sand or sandy loam. Once a season, you will have to do dirty work and remove accumulated sludge from the bottom of the tank, but in general, this solution is the most cost-effective and convenient for seasonal living.
For private houses, it is better to buy a system that provides maximum cleanliness of wastewater at the outlet of the treatment plant. Here you can not do without a station with aerators. Of the benefits: the drains after it do not smell, they are cleaned so much that they can be drained into roadside ditches. However, this solution is more expensive, and automation and compressors require connection to the mains.
Summer cottage next to the forest, seasonal accommodation, four people. Recommend a septic.
If you need cheaper and easier, then consider the Termit Profi 2.0 option. It is very similar to the well-known Tank, but it costs only 39,000 rubles. Also, the manufacturer often has promotions - you can save several thousand.
The filtration field can be arranged next to the forest. There you will dump wastewater for further treatment. So you deliver a minimum of inconvenience to yourself and your neighbors.
There is a well at the dacha, from where water is used for food purposes. Which septic tank to choose?
Obviously, a treatment station is required here, after which sewage can be dumped into a roadside ditch. If there is no ditch, it can be lowered into the ground, provided that the discharge point should be 50 m from the well.
If the soil does not accept water, then in some cases it makes sense to think about installing a storage tank with the subsequent call of sewers.
Will drains freeze in winter? Do I need to insulate a septic tank?
If they are used constantly, they will definitely not freeze - a kind of bioreactor is constantly working inside, releasing heat. In extreme cases, you can insulate by pouring a layer of straw or leaves on top.
During seasonal operation, it is recommended to fill the tank by 2/3 with drains, additionally insulating from above. So the container will not float and will not be crushed by frozen soil. We recommend that you additionally read the instructions for a specific model, the manufacturer may have a different opinion on this matter.
What will happen to the volatile water treatment plant if the electricity goes out?
Typically, such systems are very sensitive to power outages. The compressor that pumps air stops working, and after 6 hours the amount of oxygen in the drains is significantly reduced. A struggle begins between aerobes and anaerobes. Drainage can begin to ferment due to anaerobes, so after turning on the electricity, normal operation occurs within a few days.
Is there a strong odor from the septic tank?
After a conventional sump, a strong characteristic sewer smell. It can be felt even near the filtration field, so they are equipped in the most remote place.
After systems with aeration, the water is cleaner and does not smell. Unless the operating mode of the station is violated: exceeding the permissible peak discharge, power outages, the use of aggressive detergents.
Installed a septic tank with a filtration field without connecting to the power supply. How to serve it?
Once every six months, it is necessary to open the container and check the amount of sediment. If it is more than 1/5 of the height of the container, you will have to remove it. Use a bucket or a fecal pump for this purpose.
Light fractions will accumulate on the surface of the effluents. If they form a thick hard layer more than 5 cm thick, it is also better to remove it in a timely manner, because later it can significantly complicate the cleaning of the tank.
Treatment plant of an individual type
The problem of centralized drainage of sewage in holiday villages has never been solved by anyone. It has always been believed that this is the problem of the summer residents themselves, and this opinion still exists. Therefore, the owner of even a small structure is forced to solve such a problem on his own. Whatever people came up with to somehow make their stay outside the city more comfortable. The simplest and most traditional option is a cesspool. But, unfortunately, this design does not meet many standards and requirements for comfortable living. Therefore, more and more often, suburban developers began to use treatment facilities for summer cottages. This is a unique opportunity not only to collect sewage, but also to completely dispose of them.
What are local treatment facilities, or VOCs? This is a complex that is responsible for the processing of effluents and waste coming from a country house. Basically, household waste and feces, that is, organic matter, are collected here. Manufacturers of such equipment offer a fairly wide range of models, where you can find both expensive and cheap analogues. That is, there is always a choice.
But the main division is made according to the power of the complex and its energy dependence. There are both volatile and non-volatile models on the market. For the first, the presence of electricity is required. Indeed, in this unit, as a component, there are control and control units. And also a compressor that supplies air to the working area. Under its action, the process of plugging occurs, where bacteria decompose the organic components of sewage into carbon dioxide and water.
Such structures consume little electricity, so it makes no sense to talk about their cost. But here another question arises. Does it make sense to purchase a similar version of the device if the electricity supply is periodically turned off in the village? Will this unit work just as efficiently? The manufacturers have taken care of everything. If the electricity supply is cut off for a few hours, the VOC will work just as efficiently. So there are no problems in this regard.
The only thing that can scare off consumers is a rather high price. Unfortunately, for many summer residents this option is not yet available. Although we must pay tribute to the quality of processing, which is marked by a high degree of purification, reaching up to 100%. After it, the clarified water can be used to water the garden. Yes, and you will not be forbidden to lower it into open water. And the precipitated activated sludge can be used as a fertilizer. So, in many respects, this is an excellent option for creating a modern sewer network in the country.
As for non-volatile local treatment facilities, an ordinary septic tank can be mentioned as an option for a small sewer. And although manufacturers have long offered ready-made analogues, many summer residents prefer to build them with their own hands from traditional building materials. For example, from reinforced concrete rings.
For this, several pits are being built, the first of which is a sealed structure and plays the role of a collection. The second pit or well is a clarified water drain. That is, heavy particles are deposited in the first well, and then somewhat purified effluents enter the second well. Here, small and light particles are processed under the action of bacteria, and water enters the soil through the bottom of the well. There can be several wells of the second type. And the more of them, the cleaner the output water.
Septic tanks
Biological treatment of wastewater from an autonomous sewerage system
However, the time of self-built septic tanks has already passed. No one wants to deal with complex installation and construction processes, as this requires a lot of time and money. Therefore, manufacturers of sewer equipment began to offer unique, but at the same time simple designs that are affordable for the bulk of summer residents. A plastic septic tank is very relevant today. Moreover, on the market you can always find an option that is exactly right for your summer cottage in terms of volume, power and degree of purification.
Modern septic tanks are a tank divided inside into several compartments. In fact, they are very similar to reinforced concrete wells. Drains, getting inside the septic tank, alternately fill the compartments one after the other, overflowing through the partitions. In each of them, a settling process takes place, where heavy particles sink to the bottom of the tank and are processed there by living bacteria. Having passed all the compartments in this way in a few days, the water at the outlet is quite clean. Manufacturers guarantee a 95% degree of purification.
Unfortunately, this water cannot be used. Yes, and pour it into the reservoirs, too, is not worth it. Therefore, as an addition to septic tanks, filtration fields are built that provide one hundred percent cleaning and penetration of liquid into the groundwater layer. As you can see, non-volatile wastewater treatment plants do an excellent job with their duties.
All of the listed local treatment facilities operate on the principle of biological treatment. Their work is based on the method of processing organic sewage with the help of live bacteria. Experts say that bacteria can process organic matter in three days, of course, with a certain amount of sewage. That is why it is so important that this volume does not exceed the allowable one. Yes, and the effective reproduction of bacteria in this case will play an important role. This means that for this it will be necessary to create optimal conditions, where the exact volume of the structure and normal temperature conditions inside it will be the main ones.
plastic septic tank
In nature, there are two types of bacteria - some live and multiply only in the presence of oxygen, while others do not need it. Hence the modifications of treatment facilities, which are divided according to the principle of sewage and waste processing - aerobic (the presence of oxygen is mandatory) and anaerobic (without oxygen). It is impossible to say that some option is better, and some is not. Just make sure you prioritize when choosing. How?
- An aerobic recycling system requires the presence of air inside the facility or septic tank. Air can be pumped in by a compressor, which means that the system will be volatile. You can file it naturally by making an access hole. But this can be accompanied by the appearance of an unpleasant odor.
- The anaerobic system is absolutely hermetic, and air cannot be allowed to enter here. Therefore, such septic tanks are classified as "non-volatile". Yes, and problems with unpleasant odors are completely absent.
And there is also a division of modern septic tanks into northern and southern treatment facilities. In the northern regions, the construction of local sewer networks is a big problem. The soil freezes deep, so manufacturers began to offer insulated septic tanks in which water does not freeze at any temperature. This is a real breakthrough and a solution to a big problem.
Conclusion on the topic
Thanks to a modern approach to solving the problems of country sewerage, small treatment facilities began to appear on the market. This is a real victory for summer residents, who have always been in the position of renegades. Much in modern life is changing, so summer cottages began to change. Not only beautiful and comfortable houses appear here, but water supply and sewerage are also installed, and the settlements are gasified. That is, the fruits of civilization outside the city are becoming the norm.
