To this day, the water supply of suburban cottages and houses remains a pressing problem. You have to pull the pipe from the highway, which is true if the water supply system is still within reach. It is expensive and complicated. In order to dig a well, you need to take out about 10 cubic meters of soil and raise it from a depth, and first obtain permission, which is not easy at all. In the current environment, drinking water is extracted only from two-hinged wells, which are difficult to install. However, there is a way out - you can equip the Abyssinian well.
Among the advantages of the Abyssinian well, low cost should be highlighted. Turnkey price averages 25,000 rubles. As for the mine well, its digging costs about 40,000 rubles, and consumers put the same amount on the double tent device. If you do the work yourself, then driving the Abyssinian well will cost about 10,000 rubles. The well provides a fairly impressive amount of water.
Considering the benefits, one can not help but single out the speed and increase in penetration. In order to get a well-needle, there is no need to use a drilling rig, you can do without even a tripod. A drive for the drill is also not needed, as well as drilling mud. Aquifers occur in the middle zone of Russia at a depth of 2 to 15 m. For shock-rope drilling, highly professional subtleties are not necessary. If the drill suddenly gets stuck in the well, which turns out to be empty, then you can remove the drill string using a car jack.
The Abyssinian well is also good for its environmental friendliness. If you hammer a well on the sand, then the top water will not penetrate. Even in the vicinity of the metropolis, one can get water from such a well, the quality of which will not be inferior to that taken from an artesian well. For the same reason, the described type of well is not so demanding on sanitary conditions on the surface.
Driving can be done directly from the basement of the house. The work in this case is cheaper and easier, because in winter the water source will no longer freeze, therefore, the pit does not need to be done. Abyssinian wells are also distinguished by their durability. Some of those that were still clogged by the British in Abyssinia give water to this day.
In general, the average life of such a water source is 30 years, but this period cannot be called a limit. In fact, a well will produce water as long as it is in the formation. One of the main advantages is that for drilling operations there is no need to obtain permission, licenses and registration are not required.
Abyssinian wells are popular for a variety of reasons. According to their owners, drilling does not take much time. If the appropriate tools are available, then the work can be done independently. After reviewing the owner’s reviews about the Abyssinian wells, you can find out that their plus is also expressed in the fact that the water level is located at a depth of 3 m. From this it follows that it is extremely rare for sewage from the water to reach the water.
Abyssinian wells can be hidden even in the basement, this does not affect the stability of the foundation. According to consumers, with proper care and maintenance, the mine can last up to half a century. Water in such a well is usually soft, so it can be used not only for household needs, but also for cooking without additional purification.
Reviews about the Abyssinian well also indicate that the well can be equipped with a manual pump or an automated pump station. A great option is to connect both devices in parallel. In this case, you will not be affected by power outages.
What to do depth
The Abyssinian well is most often laid to a depth within 15 m. Sometimes this value reaches 50 m. However, this is extremely rare. Sometimes it happens that a water mirror is located 10 m from the surface, but in practice it is almost impossible to get water from such a depth. This is explained by the fact that surface pumps are designed for production from a depth of less than 10 m. If you purchase a hand-operated pump, it will be able to cope with water production from 7 m, while submersible pumps are not used at all, since they have a small diameter .
The depth of the Abyssinian well is determined taking into account the depth of the aquifer and soil characteristics. These parameters can be clarified in the process of exploration, but they rarely resort to its services, because the cost of work is high.
What else do you need to know about depth
The estimated depth and location of the well is usually determined independently. The maximum value also depends on which aquifer you will be installing. Experts recommend doing this on the second, because on the first the water quality is not always satisfactory, and the flow rate on the second layer is greater. But this task is not always possible to implement due to the composition of the soil and the depth of the second aquifer. If you still want to achieve it, then you don’t need to worry about the depth of the water mirror, because the liquid will be at the level of the first aquifer.
Installation conditions and components
Drilling of the Abyssinian well should be carried out in the area where the aquifer is at least 9 m from the surface. Another important condition is the composition of the soil. The soil should be sandy or consist of a mixture of crushed stone and coarse sand. It will not be possible to overcome stony ground without the use of special equipment.
The Abyssinian well has the following components:
- hardened steel tip;
- water intake valve;
- coupling for jumpers of pipe segments;
- a pump for manual pumping by a piston mechanism;
- a rubber seal in the fine filter strainer.
The trunk is a collection pipe supplying water. The core of the well is made from a pipe that is driven into the ground. Its diameter is from 1 to 2 inches. The downhole pipe should have a larger diameter than the well pipes. If you neglect this recommendation, then it will be impossible to move the pipe to a depth. To ensure primary filtration on the pipe, holes of 10 mm should be made, placing them in a checkerboard pattern.
A cone-shaped tip is put on the edge of the lower pipe, the length of which is 300 mm. Slots for liquid are made in it. The perforated pipe is wrapped with stainless wire, and then a stainless mesh or one made of plastic is applied. This will allow you to get a filter that will become a barrier to fine sand, causing siltation.
The metal mesh is fixed with tin solder or flux. It is important to exclude substances that could poison water. In the place where the well will be located, it is necessary to remove the soil, forming a hole with a diameter of 1 m. When the Abyssinian well is done with your own hands, the first pipe is driven into the soil by a cast-iron woman or by a barbell stroke. It is screwed into the ground with a frame drill. At this stage, it is required to constantly remove the rock.
As soon as the first pipe section is installed, it is strengthened in the frame, and the earth around is compacted, pouring soil. Another pipe is screwed onto the lower section. Then another segment is screwed. The total length of the pipe should be equal to the depth of the aquifer. As soon as you reach the water core, the water rises by 1 m. In those places where the pipes are connected to each other, you should use tight gaskets. Otherwise, liquid suction will occur, which will affect the efficiency of the well. In order to provide the necessary strength at the pipe joints, hemp should be used, which is pre-impregnated with oil paint.
When an Abyssinian well is installed with one's own hands, all actions have a certain sequence. The filter is washed from clay under pressure. At the upper end of the pipe, it is necessary to install a pump that will lift the liquid from the depth and pump out the upper layer until clarification.
The pump can be fixed with a flange on the casing, a threaded connection will be an alternative. During installation, you must monitor the water level. When it rises, you need to think about the tightness of the pipe connection. It can be broken during depressurization or blockage of the well. The use of cast-iron couplings should be abandoned, it is better to prefer steel - they have high-quality thread.
Pipes for a well
Particular attention should be paid to pipes for the Abyssinian well. After completion of work, the needle is not removed, as it will serve as the casing. The durability of the well depends on the durability and strength of the materials. 20 years ago there was no alternative to steel pipes, today you can find high-strength polymer products on the market.
They do not rust, do not rot and serve for decades, without changing the technical and operational qualities. The material is hygienic, it does not contribute to the growth of bacteria. The Abyssinian well is a needle-hole, which is equipped using thick-walled polypropylene 5 mm pipes. You can use low-pressure polyethylene.
More on plastic well drilling technology
To facilitate the task, a hole is dug at the first stage (approximately 1 m 3 ), the depth is 0.5 m. If we are talking about a well for year-round use, then at this stage it is necessary to achieve the depth of freezing of the soil. The filter tip is installed in the center of the recess, after which you can start drilling the Abyssinian well from plastic pipes. Do it yourself with your own hands.
Clogging is carried out by a pancake from a bar or a heavy sledgehammer. You can facilitate the process by using a garden drill. It is suitable for work at a depth of up to 5 m. The soil around the pipe is rammed during clogging, and additional sections should be screwed on.
Simplification of the arrangement can be done by drilling with water. For this, the mine is filled with liquid and left for an hour and a half. It’s easier to work on moist soil. Once you reach the sand layer, drilling will become easier. When you deepen the well, the water level rises to 1 m. After that, we can assume that the bulk of the work is completed. It remains only to install pumping equipment and concreting the site.
To raise water from a depth, you can use a hand pump or a domestic water station, in which the pump is located on top. The suction hose should be lowered into the column.
There are imperfect, but cheap ways to build a well. In this case, you will have to make a lot of physical effort. For example, you can hammer a needle filter into the soil using a sledgehammer. Another technology is drilling with a small diameter garden drill. Extension equipment will act as additional equipment.
The pump for the Abyssinian well is selected at the design stage. You may prefer the JET 82 M equipment, which has many advantages. This model is intended for domestic purposes and is most often installed in Abyssinian wells. It provides high water absorption, even in the presence of water bubbles and sand. The case has high strength, and it is based on cast iron, which provides the possibility of operation for a long time.
You can choose the Pedrollo pumps, which are used for pumping liquids with an impurity concentration of not more than 50 g per cubic meter. Such models are highly reliable and differ from others in that they have a small weight of 5.3 kg.
Water supply of a suburban area or a country house is a problem, the solution of which is not cheap. An ordinary well is not always able to provide decent water quality, while drilling an artesian well requires special permission.
Another technology is known today that provides people with life-giving moisture. This is the Abyssinian well, which can be equipped without paying taxes and additional approvals. Having familiarized yourself with the law on subsurface resources, you can find out that a well can be drilled independently up to the first aquifer.
