Conventional anaerobic treatment systems clarify sewage by 60–70%. If more thorough water treatment is required and it has to be discharged into the ground right next to the house, filtration fields with soil post-treatment are installed. But you will have to allocate a lot of space for them. personal plot. It is much more practical to install infiltrators for septic tanks, which do not require such huge areas.
Autonomous cleaning system The cottage includes a primary treatment device and a soil drainage complex or a well for storing purified water for subsequent pumping. The first element works the same in all cases - in the settling tank heavy fractions settle and fermentation occurs, as a result of which organic matter from the sewer decomposes into safe components.
The second component for each site is selected individually depending on many factors. Doing drainage yourself is cheaper and easier than a large storage well. But it will not be able to cope with a significant volume of sewage. We need a more productive setup.
Connection diagram of a septic tank with an infiltrator
It is the infiltrator for the septic tank that is such an effective soil filter. It simultaneously performs 2 tasks: final purification of water treated in a septic tank and its drainage into the soil. As a result, the degree of purification increases to 97–98%. Moreover, all moisture goes into the ground naturally; it does not need to be pumped out.
Important! Drainage of wastewater using an infiltrator is not possible on clay soils. By definition, water cannot penetrate through clay.
Inside the infiltration module there is a continuous process of oxidation of organic matter with its decomposition into harmless components. And the treated water is simply discharged into the ground.
Sewer infiltrator device
In the case of sewerage, infiltration refers to the drainage of water into the ground through a filtration layer of gravel and sand.
By infiltrator for septic tanks we mean extensive the lineup devices for soil purification. They are made from various materials, but the operating principle and design are the same for all models.
Structurally, the infiltrator is a container without a bottom with three pipes:
- entrance from the septic tank;
- day off for overflow;
- ventilation
Outwardly, it resembles an inverted basin or bucket with pipes for the movement of water and air. This structure is installed on a sand and gravel cushion - a soil filter.
In fact cesspool with drainage is also an infiltration installation. At its bottom there is also a filter made of sand and gravel, which, on the one hand, retains waste, and on the other, ensures the infiltration of clarified water into the soil.
Advice! A sewer infiltrator is best option for “lazy” and at the same time practical owners. Waste does not accumulate in it, there is no need to clean it, and it successfully copes with the tasks of cleaning wastewater.
After installation, the septic tank infiltrator does not require any maintenance or supervision. There is no need to pump waste and sludge out of it, and the internal walls of the tank are self-cleaning with the flow of incoming water. Set it and forget it. No vacuum cleaners and no additional maintenance costs.
Case design and material
When choosing an infiltrator model, you must Special attention pay attention to the housing material, which should be as resistant as possible to:
- corrosion;
- aggressive organics Wastewater;
- household chemicals.
Iron is of little use in such conditions. If it is provided reliable protection depending on all these factors, such a case will cost a lot. For a private home, it is better to choose a simpler and cheaper option.
Reinforced concrete is quite suitable, but it is heavy and requires special equipment for installation. What remains is plastic, which is not subject to corrosive processes and is resistant to aggressive chemicals entering and forming in the sewer system.
Important! The design of a model with a plastic body must include stiffening ribs. Only in this way will the infiltrator be able to withstand the weight of the soil from above for years.
Factory-made plastic infiltrator
There are two ways to install an infiltration device next to the septic tank:
- Purchase a factory-made kit.
- DIY drainage construction from large-diameter corrugated plastic pipes.
Both options are suitable for a private home. The first one will cost a little more, but it is easier to install.
Drainage capacity
The infiltrator must accommodate at least three volumes of the septic tank to which it is connected. There is always the possibility of a volley discharge of water; the drainage reservoir must take all of it. At the same time, it may already be partially filled with wastewater.
If necessary, several drainage modules can be installed nearby
Factory infiltration units have a capacity of two hundred liters or more. But sometimes a much larger volume is required. To obtain the necessary “power”, several small infiltrators for septic tanks are combined using pipes. When the first one overflows, water begins to flow through the overflow into the next tank and is drained there.
The required volume of container largely depends on the throughput (filtering) capacity of the soil - how much water can go into it per day. Sands are the undisputed favorites here, but loamy soils take a little longer to completely absorb moisture.
Often on clay soils Ah, you have to connect a storage well to the infiltration equipment. It receives excess water that has not had time to be absorbed into the ground, and from there it is pumped out by a conventional pump for discharge into a drainage trench or for removal from the site by sewer trucks.
Installation of a factory infiltrator
The installation of an infiltration unit can be done both at the stage of arranging a septic tank and after its construction. The factory model made of plastic, depending on the design and power, weighs only 10–20 kg. No cranes are required; everything can be carried by one person.
Installation of an infiltrator for a septic tank is carried out in three stages:
- Excavation– digging a trench to fit the size of the equipment.
- Formation of a filtration layer from gravel.
- Installing the container and filling it with soil.
SNiP and SanPiN requirements! The septic tank and the infiltrator for it must be 5 meters away from the foundation of the house, and from reservoirs and wells with drinking water- 30 meters.
The area of the pit on each side should be 30–50 cm more sizes infiltration equipment. You will have to dig in depth based on the height of the plastic module plus 50 cm for the sand and gravel filter from below and the same amount from above for the soil as thermal insulation. It should be one meter away from the septic tank.
Installation diagram of the infiltrator and septic tank
After excavating the earth, crushed stone of medium fractions and fine-grained sand are poured into the bottom of the trench. The thickness of the layer depends on the hygroscopicity of the soil underneath. In most cases, 40–50 cm of gravel-sand or just a gravel cushion is sufficient.
All that remains is to install the infiltrator on the bottom and connect it with a plastic pipeline to the septic tank. After checking the connections for leaks, everything is covered with earth - it will provide necessary thermal insulation and will prevent the water inside from freezing. Only the ventilation pipe should be visible from above.
Manufacturing and installation of an infiltration block from plastic pipes
As an alternative to a factory-made product, an infiltrator for a septic tank can be made from large-diameter sewer pipes. This does not require any special skills or tools. Everything can be done with your own hands.
Plastic pipes you should take corrugated ones with a diameter of 800–1000 mm. Cross-linked polyethylene, which is not afraid of frost, is best suited.
Corrugated sewer pipes are suitable for creating an infiltrator
A pipe 1.5–2 m long must be cut lengthwise into two equal halves. In fact, this is the finished infiltrator body. All that remains is to install plugs at the ends and insert the pipes. Even with minimal experience in sawing plastic, everything should work out.
Installation of such a homemade infiltrator into the ground is carried out using a technology absolutely identical to the installation of a factory analogue.
Video: installation and connection of an infiltrator consisting of two modules to a septic tank
The infiltrator allows you to significantly increase the degree of sewage water purification and bring it to 97–98%. Its installation is simple, it costs little, but it guarantees adequate wastewater treatment. You can install an infiltration block for a septic tank with your own hands. This will not cause any difficulties - its weight is light, and its design is extremely simple. You just need to consult with a specialist on the optimal container volume, the choice of which depends on the characteristics of the soil and the capacity of the septic tank.
An infiltrator is necessary for thorough post-treatment of wastewater located in the soil. Its installation, most often, occurs together with the sewerage system. An infiltrator for a septic tank is an excellent option for a small area, where it is sometimes difficult to arrange “large fields” of filtration.
What it is?
By appearance this design resembles a small container without a bottom, which is very similar to an inverted basin. But, unlike it, the infiltrator is made of durable plastic. This device is installed from the septic tank at a distance of 1-2 meters.
This device is necessary for complete purification of water and its discharge into the soil. This happens thanks to a specially designed design that releases water pressure to a shallow soil depth.
The advantages of an infiltrator for a septic tank are significant: it is lightweight, so it is quite easy to install it at home, this device is suitable for any soil, and its considerable volume can easily withstand even the most peak water discharges.
The infiltrator must be installed at the moment when the septic tank begins to not perform sufficient water purification (when installing a sewer system, this device is also installed). It is important to note: if you are going to install cleaning devices on the site of the house that can purify the water flow by 98%, you do not need to purchase an infiltrator.
Types of infiltrators
Today there are several types of this device, designed for any soil:
- For peat or sandy soil, a plastic well with a septic tank, at least 400 mm, is perfect. It will help drain wastewater.
- With variable groundwater level on loam and peat, it is recommended to install a well based on concrete rings.
- For low ground water level of sand - in-depth drainage designed for installing a septic tank. Also, under these conditions, you can use drainage, through which water will flow into a plastic well and be purified there.
- With variable and low groundwater levels on peat or loam, it is recommended to install a well based on concrete rings, in which gravity drainage will be present.
Installing an infiltrator with your own hands for water purification, as shown modern photos– it’s not a difficult matter. The main thing before starting work is to understand the technology of its installation, as well as choose the most suitable septic tank. Watch the video to see how the device is installed.
Before purchasing a device, be sure to determine the type of soil on the site, since an infiltrator for a septic tank must be purchased based on the soil.
Infiltrator design and diagram
As mentioned earlier, the main task of this device for a septic tank is ground purification of sewage water. But many people think: why not install simpler and cheaper aeration fields for a septic tank instead?
In fact, the difference between these systems is obvious - it mainly lies in the area that is required to install one or another device designed to complement the septic tank. Thanks to modern species an infiltrator for a septic tank will require twice as much to install less area than when installing other cleaning devices.
Therefore, it is important to choose this device for your home, which is perfect for a small area and can constantly purify water no worse than modern purification systems.
The operation of an infiltrator for a septic tank consists of several stages:
- Purified water flows through pipes into the container;
- Since the base of the device is equipped with a fan, oxidation of substances and their instant decomposition occurs in the infiltrator;
- After the flow passes through the filtration layer, the water flow is further purified (it is carried out in the lower layer);
- If the water discharge significantly exceeds the volume of the device, before installing it, several containers are installed into which water will flow evenly using an overflow pipe.
Based on this, we can conclude that the liquid coming from the septic tank, using this device, purifies the water from impurities and harmful additives, and organic compounds They decompose quite quickly and dissolve in water.
The process of post-purification of water in the ground is actually simple and quite fast - it can be fully seen using a diagram presented in the form of a photo.
When choosing an infiltrator for your home, you need to take into account not only the area of the house and the site, but also other important points:
- Technical structure of a septic tank.
The first thing that needs to be assessed is the water discharge, or more precisely, its excess. In other words, the device must be selected based on the actual capacity of the containers, so that the post-treatment process is 3 times greater than the capacity of the septic tank. Then you don’t have to worry that the device’s capacity is not enough for a constant, extensive water flow.
- Type of soil.
Depending on the type of soil, the rate of passage of water into the soil varies significantly. For example, for loamy soil it is much lower than for peat or sandy soil. Therefore, it is recommended to evaluate the condition of the soil and its main characteristics before purchasing so that the final purification of water in the device is at the maximum level.
Do-it-yourself infiltrator installation
Installing an infiltrator at home for water purification is not an easy task. Therefore, it is necessary to carefully study the technology of its installation.
The advantage of this device is that it can be easily installed after the septic tank. But still, experts recommend doing this work at the same time so that the structure works without failures.
The first step is to select the location of the soil in which the device will be installed. It is important to note: although the water will go into the ground purified, the installation of the device for the septic tank must be done at a distance of 3-5 meters from the house and 20 meters from open water intakes, for example, wells, rivers, and so on.
After choosing a location, you can proceed directly to installing the device yourself.
Digging a pit
The main parameter of the pit is depth, which depends on the level of underground water. It is important to note that the infiltrator for the septic tank must be installed above its rise.
There is no need to dig a big hole - optimal size designs 40x50 cm (look at the photo).
Formation of the interlayer
To filter and purify water, it is necessary to prepare a “natural” layer. It is made with your own hands from sand and crushed stone. In this case, the sand should be as fine as possible, and the crushed stone should be medium.
After preparing the mixture, it is necessary to lay geotextile - this is done only in one side of the pit and on top of the infiltrator for the septic tank (you can buy it at any hardware store).
Final stage preparatory work– filling the layer and leveling it, which must be level, as shown in the photo.
Installation of the infiltrator
Install this device You can easily do it at home with your own hands, without equipment. The weight of the device is on average 17-20 kilograms. It is important to correctly connect all the pipes as you install it in the ground, so as not to redo the work later. Immediately after installing the infiltrator for the septic tank, you must once again check the level of the filtration pad, since failure to comply with it can damage the pipes and other structure of the septic tank after-cleaner.
After checking, the pit is filled with sand. It is important to note that it is not necessary to secure the infiltrator. Most often, the after-cleaner for a septic tank is installed at a depth of 1 meter, so the sand will not allow it to “float” to the surface. Watch the video to see how to properly fill the device.
Infiltrator for septic tank Tank
The modern company "Triton-Plastic" produces modern septic tanks that differ high quality and durability. In this regard, it was the first on the market to produce supplement products for the septic tank, which are shown in the photo.
Nowadays, there are several types of septic tank Tank, which can be installed in different kind soil and perform water purification. Its design is practically no different from other septic tank options, but it is stronger, of higher quality and more durable. Depending on the model of the Tank septic tank, a certain number of infiltrators for the septic tank are allocated, which are recommended to be installed in a certain type of clay.
Therefore, when choosing a “Tank” for your home, be careful, since each model of this device is designed for a specific type of soil - otherwise the infiltrator for the septic tank will not work properly, and the water will be purified only by 30%.
Price
Depending on the type of infiltrator, you can select optimal price devices (the differences between expensive and cheap products can be seen in the photo). Nowadays it differs significantly from each other. You can buy this device on the official website, where you can find not only its price, but also its characteristics and how to install it yourself.
You can buy an infiltrator for your home on any website or in a hardware store, determining its characteristics from a photo. Be sure to check everything before purchasing technical specifications device, because it is very important that it fits your septic tank and works properly for many years.
When choosing a Tank infiltrator for your home, it is important to consider expert advice that will help you make the right choice:
- The thickness of the walls of the infiltrator for a septic tank must be at least 10 mm;
- Weight without tubes – 15 kg;
- The volume of the structure is at least 40 liters;
- Be sure to consider the type of soil and site of the house;
- The type of septic tank Tank is also important, because the number of infiltrators depends on it.
The infiltrator is an element of the system local sewerage, which provides better wastewater treatment. He has small sizes, the weight of the device is only about 15 kg.
The infiltrator produces a volley discharge of all wastewater and can be used for any type of soil.
The device is made of polyethylene, which is characterized by high quality and reliability. The infiltrator has 3 chambers; no silting occurs during use.
Soil post-treatment of all wastewater can be carried out using various methods:
- Construction of a drainage well, which is used when groundwater is deep.
- Filtering fields. Today this option is still used, but it is already recommended additional settings, biological filters.
- Using an infiltrator, that is, a device shaped like a plastic basin turned upside down. Such a device is connected to a filtering septic tank, into which 60-70% purified wastewater is supplied through a pipe. Then, thanks to a natural filter made of crushed stone, they are further purified and brought to the surface. The equipment helps improve the quality of treatment and make waste disposal safer and easier.
Infiltrator conditions
To carry out a high-quality installation of the infiltrator, you must first dig a pit rectangular shape. The distance from this pit to the septic tank should not be less than 1 m; the bottom must be covered with a special cloth, i.e. geotextiles. Then a layer of crushed stone is poured up to a height of 40 cm. During installation, the following conditions must be observed:
- A layer of crushed stone is poured in such a way that all pipes are connected freely and are not located in the thickness of this layer.
- When installing, you must remember that the device will sag under its own weight. To prevent damage to the tightness of the connections, crushed stone should be poured 1-2 cm above the infiltrator, but no more.
Septic tank "Tank"
To install a septic tank with your own hands, you need to prepare following materials and tools:
- leafy stainless steel, the thickness of which is 2-3 mm;
- wooden block, hammer, which are necessary to ensure safety metal sheet when it bends;
- pliers;
- welding machine;
- rubber gaskets, which should be 2 mm thicker than the passage (their thickness is 1.2-1.7 cm);
- metal pipes - 2 pcs.;
- ventilation pipe with a special cone-cap.
Drawing of the septic tank “Tank”.
The process of installing a septic tank “Tank” is as follows:
- first you need to calculate the volume that the septic tank will have, usually it should not be less than 400 liters;
- further produced inner layer made of steel, the joints of which must be slightly rounded to withstand pressure;
- the outer layer is made in such a way that the lid has a cone-shaped shape, this reduces the load on the entire structure;
- rubber gaskets are installed between the walls, acting as shock absorbers;
- after this the frame is welded;
- the air pipe for the “Tank” is made in such a way that it moves slightly to the side, after which it rises sharply up to a level of up to 30 cm above the ground. Such a pipe is subsequently covered with a cone to prevent debris from getting into it.
The infiltrator will stand somewhat to the side; a pipe will need to be connected to it.
Installation
To install infiltrators for a septic tank, prepare the following materials and tools:
- bayonet shovel for digging;
- shovel;
- wheelbarrow for removing soil, supplying gravel and crushed stone;
- geotextiles;
- sand;
- crushed stone;
- connecting fittings - 2 pcs.;
- special sealant.
Installation of an infiltrator for a septic tank is extremely simple if you follow certain stages of work:
- First, a pit is dug according to the size of the device, and the pipe for the septic tank of the local system should be at the level of the entrance to the infiltrator. It is better to immediately check the required box so that the equipment can be connected quickly and easily. Then you can continue deepening the pit to the required level.
- The prepared geotextile is placed at the bottom, after which it is poured even layer crushed stone to the mark set for the pipe. The crushed stone is leveled and compacted. Since the device will sag under its own weight, you can add a little more crushed stone on top by about 1-2 cm. The result is a reliable, well-compacted pillow.
- Infiltrators for a septic tank must be connected extremely carefully. This is an important stage; the reliability of the entire sewer system depends on it. Fittings are used for connections; they are selected to match the diameter of the pipes. A septic tank is connected on one side, and a ventilation pipe on the other side. When attaching fittings, additional rubber gaskets and sealant must be used. This will make all connections strong and airtight.
- Next, a sand cushion is poured. It is necessary to ensure that all cracks and cavities are completely filled; you cannot leave part of the pit unfilled. Compacted sand will serve as an excellent shock absorber. After the sand has been poured and compacted, it is necessary to begin laying the soil. The one that was taken out when digging the pit will do. At this point, the installation of the septic tank and infiltrator can be considered complete. Now it’s time for testing and starting the sewer system.
Discharge of untreated sewage effluent is strictly prohibited. To dispose of wastewater in private homes, septic tanks are most often installed. In these installations, wastewater is settled and subjected to biological treatment. However, a conventional septic tank cannot provide enough high level cleaning, so you have to purify the water additionally by installing an infiltrator for the septic tank.
An infiltrator or filter cassette is a device into which the water discharged from the septic tank enters. The purpose of installing infiltrators is additional liquid purification. This post-treatment option is especially good for small areas where it is not possible to build large filtration fields. Let's look at what this device is and how you can install it yourself.
Advantages
Can be used different variants devices for additional purification of water that has already settled well in the septic tank. However, for private households, the most profitable option is an infiltrator. Externally, this device looks like a plastic box with no bottom. Its advantages:
- the possibility of removing wastewater to a shallow depth allows the use of soil post-treatment even when the soil water is shallow;
- minimum weight plastic construction facilitates DIY installation;
- the opportunity to organize high-quality post-treatment at small area, so one infiltrator can replace 35 meters of drains in filtration fields;
- the design copes well with uneven flow of wastewater;
- the affordable cost of the structure and the ability to install it yourself allows you to reduce construction costs.
How does it work?
The process of water purification in the infiltrator proceeds as follows:
- water that has settled well in septic tanks contains a minimum of foreign inclusions;
- Through a pipe leading from the treatment plant, water enters the infiltrator, where it gradually seeps through the layer of crushed stone, finally being purified;
- thanks to the presence of ventilation, the water is not only mechanically filtered, but also undergoes biological purification under the influence of aerobic microorganisms;
- purified water is absorbed into the soil.
Advice! To ensure that the infiltrator lasts longer, geofabric is used during installation. A layer of crushed stone is wrapped in geotextile, so soil particles do not contribute to its siltation.
How to choose?
Before installing an infiltrator with your own hands, you need to choose the right model. In this case, it is necessary to take into account the performance and other characteristics of the equipment, as well as the cost of the equipment and the complexity of implementation. installation work. Experts recommend taking into account when choosing:
- One of the most important criteria is volume. The design for post-treatment must exceed the productivity of the septic tank by at least three times. Only in this case will the aftertreatment system be able to operate effectively during peak load periods.
- No less important criterion soil characteristics are also of choice. The higher the soil permeability, the fewer infiltrators will be required to organize additional treatment with equal septic tank performance.
Advice! For example, for a septic tank that purifies up to 0.6 liquid per day, provided it is installed in sandy soil It is sufficient to install one infiltrator with a capacity of 0.4 m³. If the site has loam, then the number of installations for post-treatment needs to be doubled; they are installed sequentially.
Most popular models
Today there are different options for infiltrators on the market, the most popular models are:
- Triton-400;
- Polex-300.
Characteristics of the Triton model:
- total volume – 400 liters;
- overall dimensions 1.8 x 0.8 x 0.4 meters;
- weight – 15 kg.
Characteristics of the Polex model:
- total volume - 300 liters;
- overall dimensions – 1.22 x 0.8 x 0.51 meters;
- weight – 11 kg.
Installation
It is quite possible to install the infiltrator yourself. As a rule, the installation of a septic tank and a device for post-treatment is carried out simultaneously, but it is possible to install infiltrators after completion of the installation of a local treatment plant.
First of all, you need to choose the location of the local treatment plant, and the location is chosen not only for reasons of convenience, but also taking into account construction and sanitary standards.
Advice! Despite the fact that the water that is absorbed into the soil is maximally purified from impurities, the post-treatment system must be located on maximum distance from sources drinking water. The minimum distance is determined by the permeability characteristics of the soil and ranges from 30 to 80 meters.
The infiltrator is placed at a distance of 1-1.5 meters from the septic tank, the devices are connected by laying a pipe. Here are the basic installation rules:
- First you need to prepare the pit. Its dimensions depend on the dimensions of the infiltrator, and the size of the pit should be half a meter greater than the length and width plastic container. The depth depends on how high the soil water rises.
- Next, you will need to begin forming the filter layer. It consists of medium fraction crushed stone and river sand. To prevent rapid siltation of the filter layer, it is necessary to wrap the filter layer with geotextile. This is done like this: the bottom of the pit is covered with geofabric so that the edges of the material protrude beyond the boundaries of the pit. Then crushed stone is poured in a layer of 50 cm, after which an infiltrator is installed, and the edges of the geofabric are lifted up and laid over a plastic container with an overlap.
- After installation, you need to check the correct installation using a level, since the liquid must move by gravity, the pipes must be laid with a slope.
- The incoming pipe is connected, as well as installation ventilation pipe, all connections in the installation must be sealed.
- Then a layer of sand is poured over the plastic container and a layer of geofabric, which is carefully compacted.
Proper installation is a guarantee of trouble-free system service local sewer. So, if the installation is carried out with errors, the infiltrator may float up in the spring, destroying the entire post-treatment system.
So, the advantages of using infiltrators for wastewater treatment are obvious. These devices provide environmental safety using septic tanks, at the same time, they take up little space and can be used even if the soil water rises quite high on the site. If the groundwater level is very high, it is possible to install an infiltrator on the ground surface, but in this case, the circuit will have to include a pump that will pump water from the septic tank to the infiltrator.
Infiltration devices are designed for the thorough purification of wastewater, functioning together with sewer system. Often this is the only profitable option for private estates where it is not possible to arrange an extensive filter zone. Appearance device is associated with a bottomless container. The system is installed at a distance of more than two meters from the septic tank, and its service life is designed for half a century.
Purpose
Photo: infiltrator diagramServes as a device for water purification and discharge into the ground. The design is made in such a way that the wastewater exits to a shallow depth of the soil. Advantages of the system:
- Combination of relatively low weight with enormous strength.
- The work is carried out in all types of soil.
- One infiltrator replaces eight hundred kilograms of crushed stone.
- The volume is designed for emissions in excess of wastewater standards.
- It is similar to 36 meters of drainage pipe.
- Operation of the device is simple, and installation will not cause difficulties due to its simplicity.
- Prevents the area from becoming swampy.
- Economical.
- When installing utility sewer networks, the amount of work with soil is reduced.
Conventional water purification is only 75% complete. The infiltration device solves this problem by achieving 98% filtration. Uponor is recommended.
What conditions should the work be in?
- after the water is purified, it is stored in a special container inside the system;
- the next step is to absorb moisture through a special crushed stone layer (for high-quality soil water purification);
- During operation, the infiltrator does not need to be completely filled with water, and its volume is recommended to be taken such that the peak flow rate is 25% higher.
How to choose the right infiltration system for septic tanks
To choose the right device, you need to adhere to the following points:
- Operational parameters: the total volume required is three times more power. This is a mandatory condition that will insure against an immediate influx of wastewater and when operating conditions change.
- Soil qualities. The rate of soil water absorption, which is taken into account when selecting infiltrators.
- Volume and working area, in in this case square.
How many of these elements are needed?
Photo: installation of infiltrators The quantity depends on the brand of equipment. For example, one Tank-1 septic tank requires two Triton-400s. And provided that the soil base is peat or sand, then you can get by with one additional device. Also, when choosing, you need to take into account the required power, soil and other existing terrain features.
Installation in working position
The main purpose of the design is the secondary purification of clarified sewer liquid from the ground. Some will say that other aeration fields will be suitable, but no. In the first case, much less space is needed than in the second, so installing other types is not economically profitable.
Principle of operation:
- The clarified water moves through the pipeline into a special container.
- Due to the fact that the structure is ventilated, nitrification occurs - the removal of living microorganisms and their separation.
- Additional purification is performed when wastewater moves through the lower filter system.
- After the main tank is overfilled, the liquid moves through pipes to other additional containers.
The main conclusion is that the clarified liquid after the septic tank undergoes post-treatment and is completely free of harmful microelements.
How to do the installation yourself
The main advantage of the system is that the infiltrator can be installed after the septic tank. However, sellers advise installing simultaneously with VOC.
If you do not yet have a septic tank, then before work you select a location for the device. The recommended installation distance should be at least 5 meters from the building and more than 30 meters from wells, water intakes, etc. (Rules and regulations of SNiP and SanPiN for the installation of septic tanks on sites). Next, we do the work ourselves, which is divided into several stages:
Pit development
The main criterion at this stage of work is the soil water level. You need to dig to such a depth that the system is above the average level of their rise.
The size of the pit needs to be increased by about half a meter from the installation. This is explained by the fact that at the bottom there will be an infiltration cushion, the area of which must be larger than the system.
Layer device for filtration
Photo: operating principle of the septic tank filtration pad Tank Natural filter - the joint work of crushed stone and sand. This is where it is used. The crushed stone fraction is medium, the sand fraction is fine. The bottom of the pit is covered with geotextile. This solution allows you to maintain the integrity of the filtration cushion and prevent the entry of microorganisms. They can remain in the wastewater, bypassing the septic tank along the side surface of the soil.
The next step is adding a filter pad. It will thoroughly purify the water before it penetrates into the lower soil layer. Thickness depends on hygroscopicity - the speed of passage of soil water. The final step is leveling the fill.
Installing the system yourself
Thanks very much light weight installation can be carried out independently without the use of additional equipment.
It is very important that the housing, which is already standing on the soil cushion, matches the level of the system. After which you can work on the inlet and outlet pipes, as well as the air exchange pipe.
Next, after checking the tightness of the system, the pit is backfilled with soil. Distinctive feature The advantage of the device is that it does not need to be secured additionally due to the depth of the soil backfill of 1 meter, which reliably protects the elements of the system.
There have been cases of joint installation of an infiltrator and a well with your own hands.

Without such an installation, the quality of wastewater absorption will be much worse than the incoming mass from the septic tank. Such a solution can lead to flooding of the infiltrator and the reverse flow of liquid into the VOC.
Having completed all the procedures with your own hands, the operation of the structure begins. Caring for the aftertreatment system is also done with your own hands. The condition of the pipes and the degree of clogging are checked.

Throughout the entire service life, human intervention is minimized, which gives only positive emotions.
