Installing a septic tank is a practical way to solve the problem of wastewater disposal when arranging a local sewage system. But, you must admit, it is sometimes not easy to make a choice among the variety of ready-made designs.

To simplify the task, we suggest that you familiarize yourself with an overview of the main types of treatment facilities and popular models from leading manufacturers. We will tell you which septic tank to choose based on the characteristics of its operation, and outline the main parameters of the device that must be taken into account when purchasing.

For better understanding question, we have supplemented the information with photographs various models recyclers, as well as diagrams for their installation.

A septic tank is a waterproof structure consisting of one or more sections or divided into two or three compartments or chambers. But any sewage treatment plant has its own characteristics.

Therefore, in order to choose a recycler wisely, it is necessary to analyze the types of equipment on the market, understand the principle of their operation and determine for yourself the feasibility of using a particular model.

Types of materials used

Septic tanks, which are the main element of local sewerage, are classified according to different criteria.

Although a dacha is considered temporary housing, staying there can be made as comfortable as in a city apartment if you equip a water supply system and organize autonomous drainage of wastewater.

Budget septic tanks for summer cottages without pumping, characterized by their affordable cost and autonomy, can play an important role in the arrangement of sewage systems. But you should remember that only a high-quality product will allow you to get the expected result. Therefore, the question of the manufacturer when choosing a septic tank is not the least important.

Let's figure out which model is better to give preference to. We have prepared a review of the most popular septic tanks different manufacturers, identified their characteristics and operating features. A comparative assessment of storage tanks will help you decide on a suitable tank for arranging a sewer system in your country house.

Presented on the domestic market a large number of companies specializing in the production of local cleaning equipment intended for dachas. There are many offers on the market and what to do right choice, you will need certain knowledge.

Among the general assortment of septic tanks suitable for temporary housing, there are not so many. So, the optimal solution would be to purchase an inexpensive device that does not require special or complex care. And such equipment includes anaerobic plastic multi-chamber products.

The principle of operation of any septic tank of the specified type, operating without pumping, is that contaminated water passes through several containers connected to each other.

Moreover, in each of them waste is processed with the help of organisms that do not require air.

Because the suburban construction prospers and people love to live in comfort, then the sphere treatment facilities is thriving. Therefore, we have a fairly large number of manufacturers working in this market segment. But not every one of them produces equipment for dachas. Therefore, the choice of manufacturer must begin with determining what kind of septic tank is needed

Such a process cannot be compared in activity, speed and efficiency with biological stations. Nevertheless, it is able to cope with 80-85% of contaminants. And all this without human intervention and without consuming electricity.

In addition, such equipment costs several times less than modern aeration plants.

Review of septic tank manufacturers

Although on Russian market There are quite a few products presented that fall into the budget category described above, however, there are not so many proven manufacturers.

These include manufacturing companies:

  • Rostock;
  • Multiplast;
  • Biofor.

All of the listed manufacturers have their own production facilities, design departments, and use modern technologies, which allows us to produce high-quality products.

Place #1 – Rostock company

One of the popular manufacturers is the company Rostock, whose products are valued for sufficient reliability, high quality, and affordable prices.

This organization is undoubtedly one of the leaders in the domestic cleaning equipment market and one of its largest players. The production of septic tanks and related products is the main specialization of the company.

Since the only effective budget septic tanks, manufactured for dachas, are products that operate in autonomous mode, that is, without electricity, then bacteria that do not require air are used to dispose of wastewater.

But the peculiarity of this method is the low speed of the processing process; in addition, only no more than 85-90% of contaminants are destroyed. Accordingly, additional cleaning will be required, which will have to be thought about in advance.

  • Rostock Mini- with a productivity of 0.3 m³/day it will be the optimal solution for a summer house where no more than 1-2 people live, but with low water consumption the amount can be increased to 3-4. The main advantages of the model are its compactness with a capacity of only 1000 liters, and affordable cost. What makes a septic tank one of the most profitable offers for lovers of country life in Russia.
  • Rostock Dachny- has a productivity of 0.45 m³/day, which makes the model optimal for cleaning waste from 2-3 summer residents.
  • Rostock Countryside- with a productivity of 0.88 m³/day it will become profitable solution For big family consisting of 4-5 people.

The manufacturer claims that any of the proposed septic tanks can effectively cope with their responsibilities for decades. This is facilitated by a reliable design that does not have seams, which are traditionally a weak point plastic products.

Polyethylene is used in production - a durable material that is stable over many years of use. The product warranty reaches 3 years.

There is a good chance that other companies you come across are either copying or counterfeiting these 9 products.

We warn you! Hereinafter, by septic tanks we mean any engineering structures, intended for the collection or processing of wastewater, unless otherwise indicated. These include VOCs and SBOs – local treatment facilities and biological treatment plants, respectively.

Instructions for selection and installation of VOCs

Purpose of the article: talk about the most reliable companies that have been producing septic tanks and biological treatment plants for household wastewater for more than 10 years. Simplify the selection of the appropriate equipment model based on the needs of the buyer, soil conditions on the site and the purchase budget.

Types of septic tanks

Before we talk about sewage treatment plants, let's do a little education. 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 waste until the sewer truck arrives. Relatively cheap, easy to install, and do not require maintenance as such. Use is limited by the useful volume of the container, hence the need to use water economically and rely on the services of vacuum cleaners. 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 an electrical connection for settling wastewater and its anaerobic treatment. Microbiological purification processes proceed slowly in an oxygen-depleted environment. The outlet water has a characteristic odor and is purified to a maximum of 60%, so it must be further purified. For this purpose, fields or filtration wells are used: wastewater seeps through the soil layer, after which it does not pose a threat to the environment. Sedimentation tanks are simply designed and affordable, but require maintenance. They need to be periodically cleaned of accumulated sediment, and the filtration field needs to be redone every 5 years. This solution is not suitable for high groundwater levels (GWL) and soil with poor permeability, for example, clay;
  • aeration stations. The most advanced systems for preparing household goods. drains. Through the process of settling, aeration and the use of microorganisms, the wastewater is purified by more than 90%, has no odor, and can be discharged into roadside ditches. However, such stations require connection to the power grid, and their efficiency suffers during power outages. Plus, they are expensive and require qualified maintenance.

We've sorted out the types of treatment facilities. It remains to take 5 steps to choose the one that suits your operating conditions.

FAQ

Here we have collected answers to current issues about septic tanks.

What material is the best septic tank?

Factory products for individual use are made from polymer materials: polypropylene, polyethylene low pressure(HDPE), fiberglass. They are relatively light, do not corrode, are strong, sealed and durable - all these materials are good.

The only question is to what extent their capabilities are realized in a particular septic tank design. For example, there may be a polypropylene container in which the seams are welded poorly, so it will leak after some time.

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 suit 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’t decide between a non-volatile septic tank and a biological treatment station with aerators. What's better?

If for a summer residence, choose a non-volatile sump tank, 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 have to do it dirty work and remove accumulated sludge from the bottom of the container, however, in general, this solution is the most economically feasible and convenient for seasonal living.

For private homes, it is better to buy a system that ensures maximum purity of wastewater leaving the treatment plant. You can’t do without a station with aerators. One of the advantages: the wastewater does not smell after it, it is cleaned so much that it can be poured into roadside ditches. However, this solution is more expensive, and automation and compressors require connection to the electrical network.

Country house plot next to the forest, seasonal accommodation, four people. Recommend a septic tank.

If you need something cheaper and simpler, then consider the Termite Pro 2.0 option. It is very similar to the well-known Tank, but costs only 39,000 rubles. The manufacturer also often has promotions - you can save several thousand.

The filtration field can be set up next to the forest. This is where you will dump wastewater for further treatment. This way you will cause minimal inconvenience to yourself and your neighbors.

At the dacha there is a well from which water is used for food purposes. Which septic tank to choose?

Obviously, a treatment station is required here, after which the wastewater can be discharged into a roadside ditch. If there is no ditch, it can be lowered into the ground, provided that the discharge point must be 50 m from the well.

If the soil does not accept water, then in some cases it makes sense to think about installing storage capacity followed by calling the vacuum cleaners.

Will the drains freeze in winter? Is it necessary to insulate a septic tank?

If used constantly, they will definitely not freeze - a kind of bioreactor is constantly working inside, generating heat. In extreme cases, you can insulate it by pouring a layer of straw or leaves on top.

During seasonal use, it is recommended to fill the container 2/3 with drainage, additionally insulating it on top. This way the container will not float up and be crushed by frozen soil. We recommend that you additionally read the instructions for the specific model; the manufacturer may have a different opinion on this matter.

What happens to a volatile water treatment plant if the power goes out?

Typically, such systems are very sensitive to power outages. The compressor pumping air stops working, and after 6 hours the amount of oxygen in the wastewater is significantly reduced. The struggle begins between aerobes and anaerobes. Effluent can begin to ferment due to anaerobes, so after turning on the electricity, normal operation occurs within several days.

Is there a strong smell from the septic tank?

After a regular septic tank there is a strong, characteristic smell of sewage. It can be felt even close to the filtration field, so they are installed in the most remote place.

After systems with aeration, the water is cleaner and does not smell. Unless the station's operating mode is disrupted: exceeding the permissible peak discharge, power outage, use of aggressive detergents.

Installed a septic tank with a filtration field without connecting to the power supply. How to service 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, it will have to be removed. Use a bucket or fecal pump for this purpose.

Light fractions will accumulate on the surface of the wastewater. If they form a thick, hard layer more than 5 cm thick, it is also better to remove it in a timely manner, because it can subsequently significantly complicate cleaning the tank.

At the dacha you cannot do without sewerage. After all, the water needs to be dumped somewhere. The same goes for a free-standing bathhouse. There are many designs and kits for baths available. But for some reason, nowhere does it say: “Where does it go? drain water? If you want to set up a septic tank for a non-residential dacha or a bathhouse as simply and cheaply as possible, then do it yourself, using materials... that no one needs.

If the amount of wastewater is not at all large (less than 0.7 cubic meters per day) and water is discharged only occasionally (no one lives permanently), then the standards allow us to equip a small septic tank for wastewater with bottom filtration. But before we talk about the design, you need to choose a suitable place for the septic tank.

Septic tank location and pipeline

Water from a bathhouse or other drain should be drained by gravity. Without installing an additional pump. Right? Then the drain pipeline should have a slope of 2 centimeters per meter. If the length of the pipes is 10 meters, then the pipeline in the septic tank will be lowered by 20 centimeters compared to the exit point.

If the sewer system will be used in winter, the pipeline will have to be buried below the freezing level. And this value is significant, even in average regions 1.3 - 1.5 meters. But the pipeline can be placed higher, but at the same time be properly insulated. Then rare flows of warm water will not create a continuous ice jam, unless of course the pipes are cast iron... Insulation can be made from a “skin” of polystyrene foam (sold) or a 10 cm layer of glass wool wrapped in roofing felt. Then the pipe can be placed at a depth of 0.4 - 0.6 meters.

Regular outer diameter drain pipe– 110 mm. Such plastic pipes for sewerage can be purchased without problems. But if solid fractions are not expected in the drain, for example, if the drain comes only from the bathhouse, then you can get by with smaller standard diameters - 50 mm or 40 mm.

Now about the location of the septic tank on the site. There are a number of guidelines that limit liberties in this matter. The septic tank should be located at a distance of 5 meters from the house, and 1 meter from another building with a foundation. From the road - 5 meters. From the well - 50 meters, and from the water supply - 10 meters. But the most important limitation is the groundwater level. There should not be less than 1 meter from the bottom of the septic tank to the aquifer. This is for an open bottom. But completely sealed septic tanks should not be located directly in the water. Therefore, you need to find out how deep it lies groundwater, and only after that choose one or another cleaning system.

But most likely there will be a place on your summer cottage that meets the above requirements. Then you can start building a septic tank.

Design

Since a septic tank is needed only for periodic drainage, there is no need for a large volume of it. And if so, then the shell of the septic tank can serve as old car tires. They don't have large diameter, and by burying the tires to a depth of 2.5 meters, you can get a decent tank for “one-time” use. And there is no need to dig deeper, since the sewage disposal truck does not go deeper than 3 meters.

Where can I get old tires? Contact a tire shop. There are workshops that are willing to pay for the removal of this stuff. But a septic tank made from passenger cars will be minimal in size. If you go to the Auto Garage, you can get hold of “trucks.” Do you want a large septic tank? Since there are a lot of drains, then look for tractor ones, perhaps by agriculture, possibly at car factories.

Installation of a budget option

When the trench for the pipeline has been dug, you can begin digging a pit for the septic tank. The contour is marked 5 - 10 cm larger than the tires. But such a pit will turn out to be too narrow to make it deep. It will be too inconvenient to work. Therefore, starting from a certain depth, it will have to either be expanded or dug from the surface. To dig from the surface, you will need to acquire a pair of very long tools - a “chisel” and a “scoop”. The first one can be the usual bayonet shovel on a 2.5 meter handle. And the second is a shovel, but bent at 75 degrees. Then it will be possible for her to collect soil and deliver it “to the mountain.”

Having dug a well more than 2.5 meters deep, you need to equip its bottom using a gravel filter. It is in it that invisible helpers - bacteria - will work most actively, decomposing wastewater into simple and harmless components. The filter thickness is 50 cm. First, 20 cm of sand is poured, then 30 cm of crushed stone.

Now you can put the tires in the pit. But first, it is recommended to cut off their lower side. Then water will not linger inside. This can be done easily with a regular jigsaw or saw. And in the tire into which the drain pipeline will be inserted, a hole will have to be cut across the steel cord, so you will need a metal file and wire cutters.

The tires are laid out so that they rise above the surface. This will prevent rainwater from flowing into the hole. It is also recommended to install a roofing felt seal into the gap between the tires and the walls of the pit. This prevents flooding from melted water and sediment.

After that, all that remains is to fill the soil back around the tires, and use the remaining part to make a bead around the rising tire. It is better to plant this mound with shallow lawn grass, then the septic tank will turn out simply charming.

But the septic tank must be covered with a solid lid, just in case... If you work hard, you can also adapt a cover with a hatch by screwing it with self-tapping screws directly to the top tire.

The overall result of all the work will be the cheapest but most efficient septic tank design possible. And may it last for many years...
