Most owners of country houses and dachas strive to improve them, including building a local sewage system. One option for an on-site treatment facility is a Green Rock septic tank. These products are presented in an assortment, so potential consumers must first get acquainted with the model range.
In order for the local sewage system to work stably, it is necessary to choose the right treatment facility. One of the options for a septic tank for a dacha or home is the Finnish-made Green Rock model. The products of this brand are presented in an assortment, so you need to know which model is suitable for a particular object.
general description
Products sold under the Green Rock brand are distinguished not only by their performance, but also by their operating principle. The range includes installations operating on the principle of a biofilter, and full-fledged closed-type stations that provide the highest level of purification. Product range:
- Biofilter IISI;
- VOC 05 mini;
- IISI-6;
- IISI-10;
- IISI-15.
Advice! The consumer can buy either a full-fledged deep biotreatment station or a separate biofilter, the installation of which will improve the quality of operation of an already installed and commissioned septic tank.
Feature of the device - stone filter
The manufacturer focuses users' attention on the fact that the Green Rock septic tank filters wastewater using plates or cartridges made of stone fiber. It is a natural material obtained from molten stone. Used filters are disposed of by composting.
Stone fiber filter element
Biofilter IISI
The Green Rock biofilter is a device that will help improve the operation of any septic tank. The product is mounted at the outlet of the last section of the settling tank and provides biochemical treatment of clarified wastewater.
Biofilter IISI is an energy-dependent installation, since its operation is ensured by a compressor. Clarified water is sprayed onto the filter loading, saturated with oxygen. And on the surface of the load there is a “layer” of microorganisms that contribute to the decomposition of organic matter.
Advantages and disadvantages
Advantages of purchasing a biofilter:
- the use of this device makes it possible to avoid filtration fields, since the high quality of purification will allow water to be discharged directly onto the ground;
- compactness;
- easy installation.
Minuses:
- high cost, comparable to full-fledged VOC;
- energy dependence.
Installation and operation
To install the green rock iisi 6 septic tank yourself, you need to follow the appropriate algorithm. The process begins with digging a pit in which the treatment system will be placed. The pit must be filled with sand to form a “cushion”, and also preparatory work must be carried out for further laying of pipes in dug trenches, after which the system itself must be lowered into the prepared pit.
Sewage pipes are connected to the system and a pipeline for drainage is connected. After this, for the system to work, it must be filled with water and connected to the mains. The installation is completed by backfilling the pit and trenches. In order for green rock iisi 6 to serve for a long time, operating conditions must be met:
- The frequency of pumping out the contents of sedimentation tanks is at least six months.
- The frequency of replacement of stone fibers contained in biofilters is at least five years.
Biological stations
Green Rock IISI-6 and IISI-10 plants are full-fledged treatment facilities, they differ in performance indicators.
IISI-6
The installation is a cylindrical plastic container. At the bottom of the container, the volume is divided into three chambers, with the first chamber being large (holds 1000 liters), and the second and third having a smaller volume (500 liters each). Chambers are used for multi-stage wastewater clarification.
After settling, the wastewater is directed using a pump to a biofilter located in the upper part of the installation. In this case, the liquid is sprayed over the load, that is, the principle of operation is the same as in an energy-dependent biofilter.
IISI-10
The installation differs from the one described above in the increased volume of chambers and, accordingly, greater productivity. The operating principle is the same.
Advantages of models and their disadvantages
Advantages of these installations:
- high quality wastewater treatment;
- the ability to choose the model of the desired performance.
Advice! Model IISI-6 is suitable for a house with 4-6 people. Option IISI-10 is the best choice for servicing local sewerage systems in a house with 8-10 residents.
The disadvantages include energy dependence, as well as a fairly high cost when compared with domestically produced models.
Selection and installation
The choice of Green Rock septic tanks, like the choice of any other treatment system, depends on the daily volumes of wastewater sent for treatment. Green Rock 05 is designed for a family of 3-6 people. Green Rock 10S is ideal for a family of 4-5 people. Green Rock 15 domestic wastewater treatment plant for a family of 6-8 people. Green Rock 20 domestic wastewater treatment plant for 10-15 people.
Unlike other wastewater treatment systems, Green Rock units take up little space and are easy to install. Assembly and installation of Green Rock can be done independently. To do this, you need to dig a pit for the Green Rock system. The depth of the pit depends on the depth of the supply pipe. The slope of the incoming pipe should be 1.5% per 1 linear meter and 0.5% per 1 linear meter for the outlet pipe.
In the case of a close location of groundwater, it is necessary to lay drainage pipes at the bottom of the pit and lead them into the receiving well, and secure the treatment plant itself using nylon ropes and reinforced concrete slabs 50x50 cm. If necessary, insulate the walls of the system with extruded foam. Fill the treatment plant with water before sanding.
IISI-15
This is an option for a non-volatile septic tank. The wastewater is filtered through mineralized filler. Essentially, the installation works in the same way as the 05 mini biofilter, but this model has greater productivity.
If the 05 mini filter purifies no more than 600 liters of liquid per day, then the IISI-15 installation can handle a volume of 1200 liters. The installation is not a full-fledged VOC; it is mounted complete with a three-chamber settling tank, that is, only clarified waste should enter the filter.
So, Green Rock septic tanks are wastewater treatment plants. This brand sells biofilters that are installed in conjunction with any septic tank to improve the quality of treatment, as well as full-fledged treatment facilities. The range includes both models that operate autonomously and energy-dependent models. All models are distinguished by a high degree of reliability and environmental safety, but, compared to domestically produced septic tanks, they are more expensive.
The undeniable advantages of Green Rock septic tanks
A high degree of purification is always a big advantage of any septic tank. After all, sometimes it is better to pay a lot once for good quality than to incur constant costs for additional water purification later. Even if separate biofilters from the Green Rock brand are used, they are located exactly at the outlet of the system, that is, at the most critical section of the treatment system. It is much more difficult to make a mistake with the construction of a sump than with the arrangement of an aeration field or chamber, which is why you can give preference to a biofilter. In addition, it is suitable for any type of settling tank, including industrial ones.
When wastewater enters the septic tank, it undergoes mechanical purification using a filter made of a unique stone fiber brand “Green Rock”, which is capable of retaining solid particles. It is also highly efficient, lightweight and compact.
Finnish products are really good. But every year we have fewer and fewer buyers for it. And the point here is not only that domestic developments are appearing that can solve the problem of cleaning at the same level, but the price of the issue.
Alexey Shalenok
Of course, the Finns use their know-how in these systems, but they also charge the consumer an exorbitant amount for this. There are some discoveries here, a careful selection of materials, but polymers - for washers and for the body, and mineral wool - these are not such expensive materials to justify the cost at which the Finnish manufacturer enters the market. As for our consumers, yes, almost every big city has its own “ruble”, but today, as a rule, they are rebuilt with a ready-made main sewer system. Thus, those who could afford Green Rock septic tanks purely financially cease to need them. Other consumers have to wait for sales and promotions on these very high-quality products.

Service principles
Green Rock units are easy to maintain. In order for them to always work effectively, it is necessary:
- 1-2 times a year, pump out the sediment accumulated in the sump;
- Once every 3-5 years, replace the stone fiber in biofilters.
Advice! When replacing stone fiber, the plastic washers used to load the biofilter do not need to be changed. It is enough to rinse the washers removed during the fiber replacement process with a stream of water and use them again for loading.
So, Green Rock treatment plants produced in Finland are represented by a fairly wide range of models. The consumer can purchase both a full-fledged installation and a biofilter, which is mounted as a kit to an already installed sump.
Technologies to help compact wastewater treatment plants
The Green Rock septic tank is a Finnish model of treatment systems; it is reliable, convenient and environmentally friendly. The main filter element in a septic tank is stone fiber, which at the end of its life is used as fertilizer.
The secret of the septic tanks produced by the company is that they use to the maximum those physical processes that accelerate water purification in a natural way, that is, with the help of bacteria. Thus, some Green Rock devices use the technology of spraying sewage that has previously undergone settling and an anaerobic stage of purification. When the treated wastewater is sprayed inside the container where aerobic fermentation occurs, saturation with aerobic microflora occurs many times faster. It is this method - so simple, but which still had to be thought of - that makes it possible to speed up and improve water purification.
Mineral wool is an excellent natural material that does not introduce harmful substances into water during the purification process. PVC washers are neutral in relation to nature, they do not decompose and do not release anything dangerous into the water. But on their surface colonies of microorganisms useful for water purification develop very well.
Finnish company specializing in wastewater treatment.

Green Rock in Antarctica
GreenRock septic tank installed at a research station in Antarctica,
and copes well with the tasks assigned to it in the harsh climatic conditions of Antarctica.
A septic tank made of plastic, unlike metal ones, is less susceptible to corrosion. In addition, metal septic tanks do not retain heat well, which can lead to freezing in winter. Septic tanks made of reinforced concrete also do not provide a 100% guarantee against corrosion, and they are also very labor-intensive to install and assemble.
Advantages of Green Rock septic tanks:
- Autonomous sewage septic tanks are compact in size and economical to maintain.
- Effective filtration: the filtering surface of stone fiber, with a mass of 1 kg, is 8 000 m2.
- High degree of purification with a small filter volume.
- One of the best materials for biological treatment.
- The biofilter stone fiber is replaced after 3 years and can be used to fertilize the area.
- Tanks for Green Rock septic tanks are made of polyethylene.
- Green Rock septic tanks have a hygienic certificate No. 77.01.30.485.P.14156.05.2
