Country sewage - views and device
If in the complex to evaluate the dacha plots, you can see that not all of them are equipped with a sewage system, and this applies to both centralized and autonomous. Outside the city, this issue is much more difficult to solve in the first case than in the second. However, there are some nuances here, when dacha sewage is considered with a high level of groundwater.
Determine the level of groundwater
Experts recommend doing this in two cases:
- in the spring after the snow melted;
- in the autumn when the long rains are over.
It is necessary to measure the distance from the ground and the water surface of the well, which is filled with groundwater.
If it is not on the plot, you can take a garden auger and drill in several places in the area to have a more objective picture. You can also talk to the old-timers of this village and find out how high the water in the area rises.
Tip: this is especially important to do before buying a home.
If you encounter such a problem in the garden, you should not panic, because in this case you only have to seal all the joints. About what methods exist and how to properly dispose of dirty water from the house, and let's talk in the article below.
Create a sealed system
Autonomous sewage at the dacha usually consists of basic elements, the main of which is the outer section or VOC (local sewage treatment plant). Since a high level of flood waters often does not allow the system to be installed correctly and function effectively, this can lead to dire consequences.
In this case, all efforts should be made to create a hermetic structure using rubber and silicone seals. In most cases, parts of the sewer system are connected by permanent welded joints, for example, butt and socket.
VOCs may be different, they depend on the specifics of the site and planned for their installation and arrangement of the budget. In our article we will consider the main options that are most often found in suburban areas.
Cesspit
Oddly enough, this variant of VOC can also be used in high groundwater. However, the classic version in this case is not suitable, it is replaced by sealed storage tanks, protected from them at 100%.
They can be made from:
- become;
- polymeric materials.
- monolithic or precast concrete.
| Precast Can |
|
| Monolithic w / w | It is considered a better option than the national team. The design also has an additional metal reinforcement. The technology of its manufacture will be a difficult test for inexperienced builders. In addition, it will sometimes require large financial expenses. But, still for our case, this is one of the most acceptable designs. |
| Steel tank | A simple way to solve the problem of accumulation of wastewater. It can be installed on the surface or underground. The design flaws:
You can, of course, put a stainless steel tank, but not every family can afford its cost. |
| Polymer tank | Material:
When buying, pay attention to the quality of the tank and its ability to withstand aggressive environmental factors. |
Tip: Experts do not recommend making a cesspool of concrete rings in areas with high levels of flood water.
The disadvantage of polymer and steel storage tanks is their low weight. Therefore, during installation, the instruction requires attaching them to a concrete base so that under the action of physical forces after pumping out dirty water they do not surface and do not disturb the autonomous sewage system. This technology in places with high groundwater levels is called anchoring.
Septic - inexpensive option
Fighting wastewater in this case does not require you to make significant financial investments. The sewage device on the summer cottage in this way differs from the cesspool in that the fluid in the system is cleaned biologically using anaerobic reactions that do not need air access.
In this case, use one or more tanks. The first version of such a system is called a single-chamber septic tank, after which water enters the filtration fields. The second - provides filtering capacity.
There are three and four-chamber septic tanks. Usually at high groundwater filtration fields are not used, so you have to spend money on tanks from 1 to 4, which can be costly. This method of wastewater treatment is one of the most effective.
Biological cleaning
Although the method is considered the most expensive, but it is also the most effective among the other options.
- In this case, it is necessary to purchase and install a biological wastewater treatment plant with your own hands or with the help of specialists.
- It is a sealed container of small size, resembling a multi-chamber septic tank for sewage systems.
- Aerobic or anaerobic reactions take place inside it (depending on the design).
- The station can be volatile (connected to a household electrical outlet) or non-volatile.
After treatment, the water has an optimal level of purification. At high groundwater this can be considered the most ideal option. Although the minus of technology may be the high cost of the station, the call of specialists for its connection and the operating costs of equipment.
Conclusion
From the article you learned that even with a high level of groundwater, it is possible to install an autonomous sewage system at the dacha, which will effectively carry out the tasks. However, it should be sealed carefully.
Of all the types of treatment facilities presented above, the most qualitative is the station of biological treatment. The video in this article will help you find additional information on this topic.
