Modern townspeople increasingly prefer to spend time in the hot summer months in the country. But this does not mean that people want to give up all their urban habits: a warm toilet, cold and hot water should be in the house. Do you agree?
For those who are planning the arrangement of an autonomous sewage system, the Rostock septic tank will be interesting, an overview of which we offer you. We will explain in detail how to choose a model that perfectly fits your needs. In the article proposed by us, the installation rules are also detailed.

Device and principle of operation
The problem of autonomous heating and plumbing was solved by gardeners long before they became interested in the possibility of arranging local sewage on their site.
With the solution of the last problem is associated with the appearance in the sale of septic tanks. These devices allow you to clean household drains and are a key element of local sewage. "Sprout" - one of the most popular models of septic tank.

The septic tank with the Rostock trademark is intended for the organization of independent sewage systems at facilities that are unable to connect to the centralized sewer network.
The inner space of the septic tank Rostock is divided into two chambers. The effluents entering them are cleaned by settling, filtering and separating the heavy fraction as it flows from one compartment to another.
To install the Rostock wastewater treatment system, a pit and trenches are required for laying sewage pipes. The system does not need to be connected to the power supply.
The waste water that has been processed in the septic tank cannot be disposed of in the ground or on the relief. To reset it, arrange a system of soil aftertreatment.

Device for ground treatment of wastewater
Like most similar gadgets, the “Sprout” is pretty simple. In fact, it is a single tank, divided into two chambers. One of the chambers is equipped with special filters. In order to better understand the structure of this septic tank, let us understand in principle how it works.
Initially, all sewage through the sewer pipes into the first chamber. It happens by gravity. The inlet through which the drains enter the septic tank is equipped with a damper. It does not allow the draft that has accumulated at the bottom of the chamber to be agitated.
The first chamber is a sump. In it, all drains are divided into fractions. Heavy factions settle to the bottom of the chamber: they will subsequently be pumped out. Light fractions together with liquid drains rise up. The drains, deprived of heavy fractions, are considered to be clarified.
So, clarified drains, moving upwards, fall into the next chamber. She, as we mentioned, is equipped with filters. A mesh filter is used to detain coarse dirt. The second filter is sorption. It is made of a special material - zeolite, whose thickness reaches 20 cm.
A septic tank Rostock is set up simple, but very well thought out: everything is done in it so that the device can be operated for a long time and be easy to maintain.
When the drains pass both filters, they are cleaned by 70-80%. Now they can be removed from the septic tank for purification. This procedure is performed using a multi-layered backfill or special biofilters.
With the general principles of the device and the operation of septic tanks will introduce next article. Visually visualize the work of the summer-house septic tank “Rostok” will help you video, located in the final block of our article.
Operation and care of the device
The key element of the local wastewater treatment plant “Rostok” is easy to operate. The solid fractions accumulated in the first chamber should be periodically removed. This is usually done once a year, subject to year-round use of the device.
If the operation is limited to the summer period, then the first chamber is cleaned every two years. To solve this problem, you should involve a cesspool machine.
Heavy fractions (2) deposited on the bottom of the first chamber of the septic tank Rostock (1) are removed by means of a sewage disposal machine, the sleeve of which penetrates inside the device through a hatch (3)
The sorption filter, located in the second chamber, is also reactivated approximately once a year. The zeolite layer is simply washed with a solution of ordinary table salt. You need to change filters at least once in 15 years.
To improve the efficiency of wastewater treatment, you can use special biological products. With their help, the anaerobic processes occurring in this device become more intense. Colonies of bacteria contained in the additives process the organic matter in the wastewater, as a result of which the degree of purification increases.
Comparison of strengths and weaknesses
Choosing a septic tank, we, of course, are interested in its advantages, not forgetting to ask about the disadvantages. After all, before buying, it is necessary to weigh both that and the other: the decision depends on what it will outweigh in each individual case. Therefore, we will tell about the pros and cons of the Rostock treatment plant.
We list the obvious advantages of the device.
- Durability and durability. The body of the product is made by the solid cast method: the chambers are not separated from one another. If we take into account the presence of stiffeners, then you can be sure that this design will be strong and last for a long time.
- Unpretentiousness to operating conditions. For the Rostock septic tank to work, it does not need to be connected to the power supply. It turns out that it can be used in the area where it’s not yet possible to talk about developed infrastructure.
- Quality of work. This device provides a high degree of wastewater treatment. When biologically active preparations are added to the “Sprout”, we can safely say that the drains will be cleaned up to 92%. Oil and grease do not flow into the second chamber of the tank at all.
- Easy installation. The device does not require special skills in the process of installation and in bringing the septic tank to working condition. For this purpose it is not at all necessary to involve professionals: you can handle it yourself.
- Reliability and security. The inlet of the device is equipped with a damper, thanks to which even an abrupt discharge of a significant amount of water into the sewer system will not lead to a hydraulic shock.
Installation pleases thorough design. The nozzles of the device (input and output) are attached to the body with flexible elements that allows them to remain intact even in the case of moving the tank itself during seasonal movements ground.
Still, the advantages of a septic tank Rostock are much more than disadvantages: it really will serve you for a long time and will fully pay off your peace of mind and health (+)
This device has its drawbacks:
- Low weight. The low weight of the device is a significant advantage in the process of its installation, which can become disadvantage if we consider the risk of its “ascent” from the soil during periods of seasonal lifting of groundwater waters Although the form of Rostock does not contribute to this process, it is better to consider the possibility of constructing a concrete base for fixing it.
- Plot occupancy. The dimensions of the septic "Rostock" summer cottage allow us to assert that it will occupy about 4 m2 of land. This zone can not be planted with anything other than grass and small shrubs. In this area with the addition of a meter along its perimeter, it is impossible to equip the parking of vehicles, since the septic tank can be accidentally pushed.
- Sewage costs. Pumping of non-filtered waste must be carried out using a vacuum truck. This means that your budget should include this item of expenditure.
- The location of the device. "Sprout" can not be placed where it pleases. It is necessary to take into account sanitary norms, and the fact that a sewage truck should drive up to it. So, it should be located near the road.
The disadvantages can be attributed to the nuances of the device design: it does not provide for the possibility of entering a number of effluents directly into the second chamber.
And after all here drains from washing and dishwashers which contain the various washing substances should pour in. This chemistry can destroy the beneficial bacteria that make up the biofermental agents used in septic tanks.
As for the price of the device, then opinions differ. Therefore, we did not attribute this factor to either merits or disadvantages. When you choose a septic tank for your summer cottage, then decide for yourself how much this purchase corresponds to your financial capabilities.
Speaking of "Sprout", it is impossible not to mention that this name is not one, but several devices. That is, there is a whole model range, the most popular and popular components of which we now consider.
The range of septic tanks Rostock is focused on the needs of the most diverse families: if you wish, everyone can find a model that meets their capabilities and needs
Here is a list of septic "Rostock" models that are in high demand among consumers:
- Mini. The volume of this model is 1000 liters. During the day she is able to clean about 0.3 cubic meters of wastewater. Septic "Mini" is designed for 1-2 users. It has a weight of 60 kg, dimensions 128x110 cm and depth - 170 cm.
- Suburban. With a device volume of 1500 liters, it cleans per day 0, 45 cubic meters of waste. The septic tank "Country" is calculated on 2-3 users. It has a weight of 100 kg, dimensions 170x112 cm and depth - 184 cm.
- Country. The model has a volume of 2400 liters and is able to clean 0.88 cubic meters of wastewater per day. Septic tank "Country" is designed for 4-5 users. It has a weight of 150 kg, dimensions 222x130.5 cm and depth - 199.5 cm.
- Cottage. When the volume of the tank is 3000 liters, there is a daily cleaning of 1.15 cubic meters of wastewater. Septic "Cottage" is designed for 5-6 users. It has a weight of 190 kg, dimensions 236x144 cm and a depth of 200 cm.
The inlet and outlet in each of the presented models have a diameter of 110 mm. From the top, the inlet is located at a distance of 80 cm, and the output - 85 cm.
For one or two people who constantly live in a country house, the use of this miniature septic tank is the perfect solution.
Of course, this list cannot be considered exhaustive. Sold and other models bearing the name "Rostock". They can be additionally equipped with biofilters and other systems of tertiary sewage treatment.
The standard Russian family is a mother, father and one child. If such a family will live in the summer in the country, then a septic tank will best fit for them to ensure a comfortable rest.
The prices of these septic tanks depend not only on the amount of cleaning equipment with which they are equipped, but also on the performance of different models.
As an example of price dispersion, one can cite recent prices for the simplest septic tank - Mini. On sale, this model is priced at 25-26 thousand rub., whereas the model "Cottage" in the same time period was worth 55 thousand. rub.
Septic “Cottage” is designed for year-round operation by his large family, which consists of 5-6 people: equipped with biofilters, it will save the environment its ideal state
Features and criteria for the selection of septic tank given here. We recommend to get acquainted with very useful information.
Installation of sewage treatment plant
One of the advantages of the Rostock cleaning device is that it can be installed independently, without spending money to pay for the services of the involved specialists. With standard steps septic tank installation will introduce the material we recommend.
Installation and connection of the Rostock brand wastewater treatment plant includes a number of standard steps:
A photo of
To immerse the Rostock treatment plant in the ground, a pit is being developed, the bottom of which it is poured in sand and rammed until traces of shoe
For the construction of trenches under the sewer pipeline, trenches are being developed, the bottom of which is also filled with sand.
Sewage pipes in trenches should be laid with a slope of 2 cm per meter for the free movement of waste mass
For further processing, consisting in the ground treatment of waste water, another sewer line is connected to the septic tank outlet.
The pipes are connected to the septic tank by diffusion welding, the joints are treated with a sealant to fully eliminate leaks
The sewer pipeline is laid from the septic tank to the house. This sequence allows you to properly lay or adjust if necessary pipe slope
After assembly, the system is filled with water in order to determine possible defects before backfilling. If everything is normal, the pit will be filled with sand or sand-cement mixture, if there are stagnant water in the area during the flood period.
The sewer pipeline near the exit from the house, near the septic tank and the ground treatment system must be equipped with ventilation pipes
Stage 1: Development of the pit and tamping the bottom
Stage 2: Formation of trenches for laying sewage
Stage 3: Laying trenches to the pit with a septic tank
Step 4: Remove the Sewer Pipe from the Septic Tank
Stage 5: Assembling the Sewer Pipeline at the Facility
Stage 6: Enter the sewer pipe into the house
Stage 7: Filling the pit with a sewage treatment plant
Stage 8: Sewer Ventilation Pipe
Choosing a place for a septic tank
There are regulatory documents, according to which a septic tank can be located near the house, but at a distance of no closer than five meters. This distance is considered optimal for a number of reasons.
The sewer pipe leading to the septic tank must be angled so that the drains move by gravity. Too long a distance will make it necessary to bury the septic tank too deep. In addition, the longer the sewer network that enters the sewage treatment tank, the more likely it will become clogged.
Regulatory documents, such as SNiP 2.04.03-85 and others, contain some restrictions on the location of the septic tank.
It should be located in a place located:
- 5 meters to the buildings;
- 50 meters to the water source (well or well);
- 5 meters to the side of the road;
- 3 meters to the trees.
The direction of groundwater movement is also taken into account: it should be carried out from the water source to the septic tank, and not vice versa. Practitioners also believe that with this location of the well, a septic tank may be located 30 meters from the water source. There will be no deterioration in its quality. Fifty meters - a standard that is not always possible to take into account, based on the actual size of the site.
Trenching and trenching
A sewage pipe coming from a country house or a cottage must be below the level of soil freezing. It is believed that for central Russia the depth of the trench should be about 1.5 meters.
However, this indicator is individual and depends on the specific area. The proposed slope of the pipe should be 1:50 or 2 cm / meter. Such parameters should be taken into account when digging a supply trench.
Since the most popular of the Rostock septic tank, the Dachny has a relatively small weight, two strong men (+) can easily install it.
A sand cushion should be located under the sewer pipe.
To install the septic tank itself, you must dig a pit. The parameters of the sole of the pit 60 cm should exceed the corresponding dimensions of the bottom of the septic tank. It is desirable that the bottom of the pit was strictly horizontal. The tolerance is only 10 mm per meter.
For the discharge pipe should also dig a trench. Its optimal slope is 1: 100 or 1 cm per meter.
This diagram shows all the sizes, which allows you to perfectly navigate and correctly install the septic tank Rostock on your site
Installation of sewage treatment plant
As a sewer pipe, diverting wastewater into the septic tank, used products made of polypropylene. Choose products designed for free-flow outdoor networks. Their diameter should be 110 mm. Separate sections of the pipeline should be connected using couplings with rubber seals.
Similar pipes connect the septic tank and the filtration field. To insulate both lines of pipelines, you can use foamed polyethylene or ordinary expanded clay backfill.
The septic tank itself can be installed in different ways. The choice of the optimal variant depends on the level at which groundwater occurs under your section.
- With deep groundwater. It is enough to tamp the bottom of the pit, and then lay a sand pillow on the bottom of the pit. Its thickness should be 10-30 cm. On this pillow and set the tank of polyethylene. Try to place it strictly in the center of the pit. The gap between the ground and the tank should be about 30 cm.
- In case of high location of groundwater. A reinforced concrete slab is fitted to the sole of the excavation, equipped with lugs of reinforcement connecting concrete. To prevent the tank from “floating up,” it is tied to a plate using plastic straps.
If you have problems with the acquisition of the plate, you can replace it with four standard curbstones. They will play the role of anchors. Another way out of the situation - self-concreting the bottom of the pit.
Final stage of work
To sand surrounded the pipeline from all sides, when filling the trench, the pipes are manually filled with sand. And then the development can be filled with soil, rolled away during the formation of the pit.
Each layer of sand-cement mixture, which will be poured into the space between the septic tank and the wall the trench should be carefully tamped so that even when the ground moves, the device is not damaged
Between the walls of the tank and the pit also fall asleep either clean sand, or a mixture of sand and cement. When preparing the mixture for 80% of sand, 20% of cement is added. Filling the gap should occur in layers. Each layer of 20-30 cm carefully tamped.
Before you pour the next layer of the mixture or sand, you must pour water level with the future layer in the septic tank. On top of all layers in the pit and trench is placed soil-vegetative layer.
A few words about the additional filtration of stocks
Usually, after the cleaning device “Rostok”, systems of biological or soil purification are installed.
When the level of occurrence of groundwater from 1.2 meters and deeper and sandy incoherent soil type is used filter field. So called the kit, which includes distribution and irrigation pipelines.
A photo of
One of the not cheap, but simple and easy-to-organize ways of organizing the ground treatment system is the infiltrators, the number of which is calculated by the volume of processed wastewater
As a more affordable, but also more labor-intensive installation, a drainage trench consisting of two perforated pipes laid one above the other can be used. Upper sewage discharges, lower one collects them after cleaning in a soil filter
The filtration field is constructed if there is enough space on the site for its organization. Between the conditional bottom of such a system and groundwater should be at least 1 meter
At low occurrence of groundwater mirrors, it is recommended to build absorbing wells. They take up little space on the site, but also require respect for the distance between the groundwater and the conditional bottom of 1 meter.

Filter sewer well
When the groundwater level is from 1.5 meters and more deeply, a set of Drain Tunnels is used. Rostok biofilters can be operated on any soil and at any groundwater level. For additional cleaning and disposal of wastewater after the septic tank can be installed absorption well.
When installing an additional filter, finished products are installed on a cushion of crushed stone with a thickness of 30 cm. The gap between the filter and the ground is filled with layers of rubble and sand, made alternately.
The filtering, which is also an absorption, the well can be built independently. To do this, on the same pillow from rubble install 2-3 reinforced concrete rings. With the function of the absorption well to successfully cope drain pit of tireswhich device we recommend to familiarize.
Wastewater entering the septic tank through sewer pipes is not 100% cleaned in it, but this means that they need to be cleaned up using additional filters or at least drainage well
It is necessary to perform waterproofing of the resulting hull, after which it is filled in layers of 100 cm first with sand, then with gravel or rubble. The fraction of each lower backfill layer must be smaller than the overlying one.
If the lower ring of the well is buried in the sandy soil, which does not have good filtering qualities, then arrange lateral drainage. To do this, either a perforated concrete ring is initially used, or holes are drilled for a drainage stream in the walls of the ring after installation in the pit. The diameter of the formed holes is 10 mm, the spacing is 5 - 10 cm.
Conclusions and useful video on the topic
It is said that it is better to see once than to read or hear. Therefore, as a visual demonstration of the principle of operation of the Rostock septic tank, we invite you to familiarize yourself with this video:
With the process of installing a septic tank you will be introduced to the following video. You will see a phased installation of autonomous sewage "Rostock" of the Zagorodny model with the arrangement of a filtration field:
It is not true that the romance of country life must necessarily be accompanied by a rejection of urban benefits. On the contrary, summer vacation in the country should be as comfortable as possible. Let you have hot and cold water, warmth on a cool day and, of course, an autonomous sewage system that allows you to dispose of wastewater without harm to the environment.
