If you are the owner of a dacha, then you should be aware of the issue of an autonomous sewerage device. Quite often, consumers are faced with the problem of choosing a model. Buyers read reviews, from which they manage to understand that among the large assortment of ready-made containers that are presented on the modern market, the DKS septic tank stands out. As practice shows, the Country Sewer Systems company produces high-quality structures that have many positive features and affordable prices.
Septic Tank Overview
The production of the above structures is carried out from sheet polypropylene, its thickness can be equal to the limit from 5 to 8 mm. Such structures are divided into three components (the first chamber, the second chamber and the third chamber). The first compartment is the primary clarifier, the second acts as a secondary clarifier. But in the third chamber there are biofilters.
Wastewater enters the primary sedimentation tank through a pipe and is separated into light and heavy fractions. The overflow, which connects the second and first settling tanks, is locatedat a third of the height of the tank. This significantly reduces the content of impurities in the second chamber, which is especially true compared to the first.
The process of sedimentation and clarification of sewage continues in the second compartment. The DKS septic tank uses in its work not only the mechanical separation of impurities, but also the technology of anaerobic digestion. The presence of oxygen is not required. During the course of the reaction, methane is released, so such structures are called methane tanks. Bacteria that are present in faeces take part in the decomposition of contaminants during metabolism. Water seals eliminate the spread of an unpleasant odor that comes from a septic tank.
The movement of clarified wastewater further occurs through the overflow pipe, the water ends up in the biofilter, so mixing is completely excluded. A drip sprayer on the overflow pipe ensures the distribution of water over the brush load. Not so long ago, manufacturers used expanded clay-based loading instead of ruffs. On the surface of the former, water is saturated with oxygen, which contributes to the formation of aerobic bioflora, which develops in favorable conditions.
The biofilter will work fine if the capped pipe is properly arranged. It is necessary for the intake of air, which is involved in the life of aerobic microorganisms. Effluent that passes through the biofilter ends up in the drainage system, they bypass the sump and outlet pipe.
Drainage in this scheme is a perforated pipe, through its holes clarified drains penetrate into the soil, whereare infiltrated. The sediment is periodically removed through the neck, beforehand it accumulates at the bottom of the first and second compartments. Maintenance and revision of the system is carried out through the second neck. In winter, to avoid freezing of containers, it is recommended to deepen the structure using a neck extension kit. It is purchased separately by the consumer.
Features of different models
The DKS septic tank is presented for sale in several models, each of which is designed for a certain number of people living in the country. If you plan to operate the house all year round, then this should be reflected in the choice of design. For example, for an autonomous sewerage device, which is installed in a weekend cottage, a Mini septic tank is perfect. Its volume is designed to serve 4 people maximum. The device will process 120 liters of sewage per day.
The DKS Optimum septic tank and the DKS-15, DKS-25 models differ in processing capacity per day and the weight of the structures. It is based on polypropylene, which is a lightweight material, so the installation of the container does not involve the use of special equipment and human effort. The structure is installed in the prepared place. The housing allows you to place the structure next to the house.
The septic tank "DKS 15m" and "DKS-25 M" assumes the presence of a storage tank for installing a drainage pump. These options can be used in areas where there is a high level of groundwater. These solutions in winter can be used together with a kit thatsinks into the soil. Its elements are classified by height and execution.
Additional features of septic tanks. Consumer Reviews
The DKS septic tank, reviews of which you can read below, is made of polypropylene. Due to this, according to consumers, the structures are light in weight and are sold at affordable prices. This allows the system to be easily transported to its destination.
Today, the manufacturer mentioned above offers many models of wastewater treatment plants for sale. All of them differ in performance, parameters, weight and approximate cost. For example, a septic tank "DKS 15" can be purchased for 35,000 rubles. The width, length and height of the device are 1100 x 1500 x 1100 mm. The mass reaches 52 kg, and the productivity per day is 450 liters.
The septic tank "DKS 25" is a system with a capacity that reaches 800 liters per day. It weighs 72 kg and costs 47,000 rubles. Its dimensions are larger and equal to 1300 x 1500 x 1500 mm. The septic tank "DKS MBO" is offered in several variations, which differ in performance. For example, the MBO 0.75 model is capable of cleaning 750 liters of sewage per day. You can buy this version of the device for 68 rubles. In this line, this cost is the most affordable. If you have the model “MBO 1, 0” in front of you, then this indicates that its productivity is 1000 liters per day, and the system weighs 92 kg. You can buy it for 73,000 rubles.
Installation order: choice of location
To install the described system for wastewater treatment, at the first stage it is necessary to select a place. It should be near the house, but it is important to ensure that a sewage truck can drive up to pump out sludge. At this stage, you should analyze the soil where the cleaning system will be located.
It will be necessary to know how deep the groundwater is. The correct location condition is the proximity of the septic tank to the corrugated sewer pipe from the house. When installing DKS septic tanks, it is important to ensure their remoteness from engineering networks and sources of electricity. You should not choose a place near a tree that has a strong root system.
Installation of the tank
The next step is to dig a rectangular hole to mount the working tank. Next to it there will be a trench for placing pipes. The bottom is covered with an even layer of sand, the thickness of which is 10 cm. A septic tank "DKS 15m" is installed in the pit, reviews of which you could read above.
From all sides, the system should be covered with clean sand. It's better if it's wet. During installation, water is constantly added to the tank to keep the structure in a horizontal position. On all sides, the septic tank is lined with foam or other thermal insulation.
Pipe installation
As soon as the septic tank is in place, and you manage to sprinkle it with sand for stability, you can proceed with the installation of sewer pipes, theyit is necessary to give a slope for the flow of effluents into the tank. The optimal distance from the septic tank to the house is a limit of 3 to 6 m.
The pipes from the drain should be directed straight to the tank. If it is impossible to avoid turns in any way, then a rubber pipe should be used at the bend. The tank is leveled with a level, during which the sand around is periodically compacted. Pipes are also covered with soil.
Installation of ventilation and drainage pipes
In order to ensure the removal of water treated in the septic tank, a drainage well or corrugated drainage pipes should be used. The latter option is more profitable than a well, but you must decide on the choice of a particular system yourself. Pipe installation requires additional underground space above the water table.
Drainage pipes must be placed in a trench, they are corrugated rubber pipes with holes at the ends. To do this, prepare a trench, the depth and width of which are 0.5 m. Its length will be 10 m, if space allows. Pipes are laid with a slope of 1 cm per meter.
The bottom of the pit should be lined with polypropylene, and then the pipes should be laid and covered with expanded clay. The surface is covered with soil. Ventilation will be required to ensure proper breakdown of organic matter. The pipe for this is installed in the tank, but its location must be considered on an individual basis.
Features of septic tank maintenance
Betterlocate the treatment system within easy reach for occasional maintenance and scheduled inspections. When installing, follow the instructions and consult with specialists. Proper installation will simplify use and will not bring additional trouble.
For reference
Designs of septic tanks made of heavy materials provide for the use of special equipment during installation. This cannot be said about the treatment facilities of the DKS, which are based on polypropylene. Its light weight allows for easy transportation as well as installation without special equipment.
Conclusion
The company's range includes the simplest models and complex systems, the latter of which are designed for operation in problem areas. All this expands the possibilities of choice. Before starting work, it is important to consider that seasonality will not affect the functioning of the system, so installation can be done in the winter without additional insulation manipulations, which is very convenient and reduces labor costs.
