The urgent question of how to choose a septic tank for a private house, all the more urgently confronts the owners of suburban real estate. The whole reason is that even a villager today is very much spoiled by the benefits of civilization and strives to ensure comfortable living even outside the urban environment. The use of a warm toilet, shower and sanitary appliances almost anywhere became possible with the advent of cheap materials for the device autonomous sewage. Its main component is a facility for the accumulation and disposal of household wastewater from the house, which is called a septic tank.
What are septic tanks for use in country houses
The cheapest and simplest option of a septic tank is a large tank or any airtight container, which includes a sewer pipe. This tank is buried in the ground below the depth of soil freezing. Most often it is more than 1.5 m from the surface. In fact, such a device is an ordinary cesspool, only it is not broken leak, and the water does not flow into the surrounding capacity of the soil.
Since such systems are cumulative, liquid water remains in them. In the case of even a minimum of household appliances and a shower, the filling is quite fast, so regular pumping is required, which costs money. However, due to the relative availability of this type of septic tank in rural areas, people use it to equip their homes.
Helpful advice! The problem of the need for frequent pumping of the cumulative septic tank can be solved in a simple and logical way – by increasing the volume of the tank. The most convenient way is to bury a tank equal in volume to the tank of an assenizator machine. Is it about 5 – 6 m? for the tank on the basis of the car GAZ or ZIL and 8 – 10 m? on the basis of KAMAZ. From experience we can say that the filling of the 8-cube capacity by a family of 4 people using all sanitary fixtures takes 3 weeks.
If you still have a question, how to choose a septic tank for a private house, the price of which is minimal – the answer is simple. This is a cumulative capacity. The cost of such a reservoir of metal artisanal production is approximately 60 cu for 1 m. That is, the capacity of 5 m? will cost $ 300, about $ 100 more. will go to pay for the work of the excavator, although this item of expenditure is the same for all types of septic tanks. In the future, you will have to constantly make sure that the capacity does not overflow and to pay the nightman for about $ 7. for the removal of sewage.
The second version of septic tanks provides for the organization of the separation of wastewater into components of different density. In this case, more solid waste accumulates in the tank, and the liquid after settling just go into the ground. Water after such pre-treatment is not suitable even for technical use as irrigation for plants. At the same time it is quite safe for the soil, passing through which is filtered before entering the aquifers.
The advantage, and significant, of such septic tanks is that they, having an acceptable cost, require not so close attention and maintenance as storage tanks. The disadvantage of such local stations is that it is forbidden to install them on a site where there is a sufficiently high level of groundwater or clayey soil that is not capable of filtering drains.
In addition, it is forbidden to bury them in those areas where water is supplied from a well or well. Therefore, before choosing a septic tank for a private house, the price of which does not exceed reasonable limits, and the efficiency is high enough, it is necessary to thoroughly study the characteristics of the soils on your site. Also important is the depth where the groundwater lies.
If you have material resources and you want to equip your country house with modern means of sewage treatment, you need to purchase a local sewage treatment plant. About options how to choose a septic tank for a private house, the price of which can exceed $ 200, read on.
In the local sewage treatment plant, the sewage is completely purified by sludge and filtering to such a state that their direction is acceptable, for example, for watering plants. They are cleaned not only in a multistage system by mechanical filtration, but also with the help of biologically active preparations, which are colonies of anaerobic bacteria that process metabolic products and organic impurities.
Such deficiencies are deprived, apart from the price, beyond the reach of the general population. In addition, aeration in these devices is carried out with the help of electric ventilation, which makes it impossible to use such a system in areas where prolonged interruptions in power supply occur.
Helpful advice! The use of multistage sewage treatment plants with a biological filter implies a gradual accumulation of the substrate. And it is an excellent fertilizer for any crops. It is necessary to take care of its removal from the tank and moving it to the garden, which can be done in spring and autumn.
In addition to the above criteria, there are others by which existing septic tanks can be divided into types. Thus, the method of placement in the pit is also an important argument in the question of how to choose a septic tank for a private house. After all, there are very small areas or only 2 – 3 meters to the neighbor’s fence. In this situation, you can choose the choice of a septic tank with a vertical arrangement.
For him, of course, you have to dig a deeper pit, but it will perfectly save space in breadth. However, this installation option is not suitable, for obvious reasons, in areas where groundwater is close to the surface. Here it will be preferable to install a horizontal device.
Helpful advice! It is necessary to keep in mind that the septic tank should be located more than 50 m from the source of water supply, not less than 5 m from the house, even the neighbor’s one. Observance of these rules will ensure your sanitary safety.
The wipers are different in the material of which their body is made. Today, in addition to metal and concrete structures, there are:
- polyethylene septic tanks. They are the most purchased because of their amazingly low cost and lightness. At the same time, plastic does not tolerate adverse conditions very well, especially temperature drops. Although modern types of polymers may well compete on these indicators with metals. If you do not know how to choose a septic tank for a private house, the price of which is lower, stop at this option. Modern plastic wipers are a good budget option for each country house or cottage. They are fully capable of tolerating temperature surges and the detrimental effect of aggressive chemical components of wastewater. They are produced in any form using a seamless technology of multilayer plastic, which greatly increases the reliability and strength of the container;
- polypropylene septic tank It is famous for its high strength and low susceptibility to very high temperatures. He is able to take in a liquid with temperatures up to 140 degrees. If you decide to install a very durable version of a septic tank, which practically does not corrode, then the polypropylene version is just right;
- fiberglass cleaner even more durable than polypropylene. The material for its manufacture is made from resin. The walls of such containers are reinforced with reinforcement. For this, fiberglass is used. If you don’t have any idea how to choose a septic tank for a private house, where many chemicals are used during household exploitation, then this option is the best fit. The chemical properties of fiberglass are so unique that they allow using this material even in a very inhospitable environment. Therefore, such wastewater treatment plants are often operated at car washes.
We considered several aspects that should help answer the question of how to choose a septic tank for a private house. Of course, much depends on personal prejudice and local conditions, so everyone makes their own choices, and the article gives only guidelines for this.
