The easiest way to ensure country cottage area water - make an Abyssinian well with your own hands. Within five to ten hours after the start of work, the owners of the dacha will receive the first liters of their own clean water. The equipment that is used is so compact that it is possible to install an Abyssinian well even in the basement of a residential building or in inspection hole garage.
Principles of creating an Abyssinian well
The idea of the design is very simple and consists in piercing the soil to the depth of the aquifer with a pipe about one inch in diameter. To do this, attach to the end of the pipe fine tip, thanks to which a needle hole is created.
This uses pipes with a diameter of only an inch and a half. A self-priming pump operating on the principle of creating a vacuum is mounted on a recessed pipe. If there is not enough water coming from the finished well, another needle well can be built on the site with your own hands.
Location of classic water intake workings: as you can see here, an Abyssinian well can be built on light sandy soil
Despite the relatively low costs of labor and materials to create such a well, it is not possible to install it on every site. First of all, you should make sure that the water level that is reached after opening the aquifer is no more than 8 meters (the so-called piezometric level). This does not mean that the depth of drilling a well or passing a needle will necessarily be 8 meters. It can reach 10-15 meters, and in some cases for an Abyssinian well it is necessary to go deeper even 20-30 meters.
You can find out the value of the piezometric water level on the site by interviewing neighbors who already have a well or well. If it turns out that the water is somewhat deeper, a meter or two, it is still possible to make a well of this type, but this will require going deep into the ground a couple of meters.
The condition of the soil should also be correctly assessed. On light sandy soils, an Abyssinian well can be made without any problems. But if the soil turns out to be too hard, containing boulders and stones, the project will have to be abandoned.
Pipe, filter needle and other nuances
The functioning of any well, including the Abyssinian well, depends on the quality of the pipe. It is best to use inch or one and a half inch pipes, metal or plastic, which are cut into pieces 1-2 meters long. As the pipes are immersed, they are extended to the required length using threaded connections. They are sealed using sanitary flax, silicone, oil paint and so on.
In addition, special couplings are used. It is very important that the pipe connection is as reliable as possible. Any violation of the tightness will lead to damage to the entire structure.
The diameter of the tip should be slightly larger than the diameter of the pipe to ensure free movement of the structure through the soil.
At the end of the pipe, it is necessary to install a special needle filter, which will facilitate the pipe’s penetration into the ground, protect the Abyssinian well from silting, and also ensure the purity of the incoming water. It is best if the needle is made of the same material as the main pipe. This will prevent possible electrochemical corrosion.
To make a filter needle from a galvanized metal pipe, you need:
- Drill holes with a diameter of 5-8 mm in the pipe, placing them in a checkerboard pattern.
- Solder a stainless steel mesh on top. As an alternative to mesh, you can use wire that is wound around the perforated end of the pipe, leaving a gap between the turns. The wire also needs to be soldered.
- Weld a spear-shaped tip to the end of the pipe. Its diameter should be slightly larger than the dimensions of the pipe so that the structure following the needle moves freely through the soil.
A reinforced polypropylene pipe is quite suitable for such a well. To make a needle filter from PVC pipes follows:
- Insert the filter mesh inside the pipe.
- Secure the mesh using the fusion method.
- Perforate the pipe by making slits on its surface using a hacksaw.
Some experience with PVC pipes is required to perform these operations.
All necessary materials can be purchased separately at hardware stores, however ready set for an Abyssinian well will save time and effort.
What is better - hammering or drilling?
To make an Abyssinian well on your own, two methods are used: driving and small-diameter drilling. To drive a structure into the ground, a “driver” is usually used. At the same time, water is constantly added to the pipe. When the water suddenly sinks into the soil, the structure is deepened by about half a meter, after which you can begin installing the pump.
When creating Abyssinian wells, it is easier and more convenient to drill a small diameter well
For self-creation The driving method for the Abyssinian well is excellent, but when using it, a number of dangers must be taken into account. There is a possibility of passing by the aquifer. In addition, if a stone is encountered at great depths, the structure may be completely damaged.
The method of preliminary drilling with a small diameter requires the involvement of a team with special equipment, but it guarantees the presence of water in the well. This method is clearly presented in the video:
Classic order of construction work
The task of driving the pipe into the ground looks quite simple. However, in order for all operations to be successful, a number of nuances should be taken into account. Experienced builders It is recommended to make an Abyssinian well as follows:
- Select and mark a location for the well.
- Dig a hole approximately one cubic meter in volume.
- Pass the upper layer soil with a garden auger to remove some of the soil.
- Start driving the pipe into the soil using a load weighing approximately 30 kg (cast iron, “pancakes” from a rod, etc.) or start drilling.
- The pipe should be in the center of the hole; a certain amount of soil is gradually added to it, which is compacted.
- Screw additional lengths onto the main pipe successively to ensure the required length.
- Once the aquifer is reached, the filter should be washed to remove clay with water supplied under pressure.
- Set manual piston pump and pump out the cloudy water layer until the water becomes clear.
- Concrete the area around the well to prevent runoff and contaminants from entering the well.
After installing the well, it is connected to the house water supply system, if necessary.
Abyssinian wells are durable and easy to use, the main thing is the right location
The advantage of Abyssinian wells is not only their simplicity of design. They are durable and very easy to use. This small devices, which will not cause any serious damage to the landscape. Wide access roads will not be needed for their construction and operation. Finally, if necessary, you can remove the pipe from the ground and install it in another suitable place. At the same time, the water coming from the Abyssinian well always remains fresh and clean.
If for a private house or cottage you need stable source supplies clean water, then an inexpensive Abyssinian well can handle this. It is easy to build, and it is capable of supplying a sufficient amount of water - 1-3 cubic meters per hour. If you think that this volume of water is not enough, then nothing will prevent you from installing a second well. In this article we will describe the technology for constructing an Abyssinian tube well.
How it works
Abyssinian well by design, it is a well, which is created by driving metal pipe sections of 25 mm, 1 - 2 m long, into a suitable place. The pipes are connected to each other by threaded couplings sealed with silicone or sanitary flax. After this, a self-priming pump is installed, with which you can create a vacuum in the pipe, and thus pump out the water.
Making an Abyssinian well with your own hands is not difficult and there is no need to use bulky special equipment to construct it; you can even install it on the veranda, in the garage, basement and even in the kitchen. Below we will provide instructions for installing it.
Where construction is possible
It is necessary to install such a well in areas where the aquifer is located within 4 - 8 m of depth or in places where up to 15 meters there is sufficient pressure in the aquifer, which can raise water to a depth of 7 - 8 meters. If the water from the formation rises slightly below 8 m, then you can simply install a pump by deepening it into the ground.
The soil at the well site should not contain large pebbles or stones. In addition, it must not be solid.
The main part of the Abyssinian well is a perforated pipe with a head (wedge tip) and a filter. The tip should be 20-30 mm larger in diameter. It is advisable to make the filter from a metal that is the same as the material from which the pipe is made: this will reduce the level of electrochemical corrosion. Holes of 6 - 8 mm in diameter are drilled in the pipe along the length of the pipe by 0.6–0.8 m. In this section of the pipe, wire is wound with a gap of 1–2 mm for the free passage of water. After winding, the wire is soldered to the pipe in several places and at the ends of the wire. Then, using soldering, a plain weave mesh made of non-ferrous metal or stainless steel is secured.
Used for deepening pipes various devices, however, it is better to first dig a hole 0.5-1.5 m, and then drill a well 1-1.5 m. The first pipe with a fixed filter and tip is inserted into the well, leveled vertically and compacted around it with soil so that the pipe does not move when scoring.
It is also necessary to ensure verticality when deepening the pipe.
A pile driver is often used to deepen pipes, but other devices can also be used. Deepening a well pipe with a metal rod with a diameter of 16-22 mm inserted into the pipe consists of raising the rod 1 m high and applying sharp, vertical blows to the tip. As a result, almost all the load falls on the tip. You can lengthen the rod as the well deepens, or you can attach a flexible cable to the top of the metal rod. This method is called shock-rope.
It is advisable to harden bottom part rod to prevent it from riveting or, if necessary, remove the riveted metal over time.
The technology for deepening pipes for an Abyssinian well is as follows: it is necessary to use a headstock weighing 25–30 kg, this device is lifted up by the handles and sharply lowered, the shock load must fall on the nozzle attached to the headstock pipe. When deepening the well, the nozzle is moved up the pipe and, if necessary, another pipe is screwed on.
If the depth of the aquifer is unknown, then when the pipe is clogged to 4 - 5 m, periodically check whether water has appeared. If you have a thin aquifer and it is not known at what depth it is located, then you can drive the pipe lower and not get water.
If the tip is in the aquifer, then water absorption begins, this can be determined by pouring water into the pipe - quickly draining water indicates that you can connect the pump and pump water in the well.
If the Abyssinian well is installed in clay soils, then the filter mesh may become very dirty, and you may not realize that you have hit an aquifer. In this case, it is better not to rush and when even a minimal amount of water appears in the well, you need to pump it, and if possible, then rinse the filter, passing every 0.5 m. To do this, use an electric pump, insert a hose into the pipe and rinse the mesh with clean water.
An electric self-priming pump is used to lift the water. You can also use a piston pump. After installing the pump and pumping the well, a clay castle is placed around the pipe and a concrete blind area is made. The time required to construct an Abyssinian tube well is about 5-10 hours, and in most cases depends on the nature of the soil and the depth of the aquifer.
An Abyssinian well will last 10-30 years, the period depends on the aquifer, the quality of the work and the material used. Water can be pumped continuously from a well for several hours; the productivity of the well is usually 1-3 cubic meters. water per hour.
Video
We bring to your attention a video dedicated to the drilling and installation of an Abyssinian well
Water supply country houses and dachas remains a serious problem: pulling a pipe from the main line, if one is still within reach, is difficult and expensive. ? It is necessary to remove at least 10 cubic meters of soil, and not remove it from the surface, but lift it from the depths. And you also need permission, which is not at all easy to achieve; in addition, given the current ecology, drinking water will probably only be provided by a two-tent well, which is quite complex in design. But some time ago, Russia rediscovered: you can plug an Abyssinian well with your own hands. This solves all water problems at once, and is so effective that some people simply cannot believe it.
A little history
In the era of colonial wars, during the Abyssinian operation (1867-68; now Abyssinia - Ethiopia), the British massively used a Norton drill to supply water to the troops (see figure below). This allowed the colonialists to advance deep into the desert and push the Aboriginal troops into completely waterless places, which determined the outcome of the campaign. The rumor about the “Abyssinian wells” spread throughout the world, and even the British themselves stopped calling it Norton’s.
Notes:
- Norton's authorship of his drill was disputed by the German Scheetz, also a famous mining engineer. I did not achieve success, but in the literature one can find indications that the Abyssinian well is clogged with a Sheetz drilling rig. This is not true; The Sheetz drill is used in professional drilling for other purposes.
- To the picture (below): at self-production The first drill rod is turned into a filter by drilling 5-10 mm holes in it. The spear tip can be forged or welded, but must be 20-60 mm wider than the rod. The wider the spear, the slower the penetration, but it is easier to remove a stuck drill. The valve is necessary with a top suction pump to prevent loss of vacuum. In a well with a submersible pump, a valve is not needed.
About 20 years later, the Abyssinian well was tested in Russia. In Tsarskoe Selo, 5 wells were plugged at random by unskilled workers; 3 of them gave drinking water at 1-1.5 buckets per minute. The aquifer was reached at a depth of 2 to 5 fathoms (4-10 m). The rate of penetration was 3 to 5 feet in 5 minutes. Twice the drill got stuck in the limestone; each time it took about half an hour to remove it.
According to the reviews of our contemporaries, the advantages of the Abyssinian well have not deteriorated at all due to changes in living conditions. In preparing this work, about 3,000 reviews were studied. No more than 10 anonymous, obviously slanderous and libelous articles were found; the adequate reaction is unanimous: digging an ordinary well is justified only in one case - where, due to geological features, an Abyssinian well is impossible! The fact is that the flow rate of a well depends mainly on the saturation of the formation with water, its permeability and internal pressure in the formation, and almost does not depend on the diameter of the well.
What's good about it?
The advantages of the Abyssinian well are so high that simply listing them is not enough; you need to describe them in more detail.
Cheapness
Turnkey Abyssinian well price in middle lane does not exceed 25,000 rubles. (with an average of 14,000 rubles), plus water-lifting equipment will cost somewhere between 5,000-9,000. Just digging an ordinary mine well will cost at least 35,000-40,000 rubles, and installing a double tent with a top will have to cost at least the same amount.
Note: a double tent is not a booth over a well, it is a top, a log house. A double tent is a type of water intake device, it is at the very bottom of the well.
When plugging an Abyssinian well yourself, new special materials and equipment will cost approximately 8,000-10,000 rubles. The Abyssinian well is not demanding on their quality, and everything necessary for it can be made yourself from scrap metal at hand for free. But in this case you will have to break things down, and some unforeseen expenses cannot be avoided: the appetite from drilling is aroused brutally, and when the minnow finally gurgles (see below), even a non-drinker wants to choke down a glass. Not water.
Speed and ease of penetration
To drill a needle hole, you don’t need a drilling rig; you can even do without a tripod. There is no need for a drive for the drill, no drilling fluid, and there is no need to drive a hole for drilling.
The depth of aquifers in the central zone of the Russian Federation ranges from 2 to 15 m. You don’t need to know any highly professional subtleties for percussion-rope drilling, and in 95% of cases two strong men drill to water in a day, or even in two hours.
If the drill is stuck or the well is empty, it is also not difficult to remove the drill string with the projectile - it is simply pulled out of the ground with a car jack, resting it against the headstock, see below. Sometimes, in moraine soil stuffed with boulders, the column has to be hit from different sides with a sledgehammer until it loosens.
Environmental friendliness
Correctly plugged well into sand (also below, corresponding section) due to the lack of casing pipe prevents the penetration of high water (melt and flood waters) to the water intake. In the vicinity of the metropolis, it is quite possible to obtain water from an Abyssinian well, the quality of which is not inferior to artesian water.
Sanitation
For the same reason, the Abyssinian well is less demanding on sanitary conditions on the surface. It can be hammered directly from the basement of the house! In this case, the work is even simplified and cheaper: in winter the well cannot freeze, so there is no need to make a pit.
Durability
Many of the wells clogged by the British in Abyssinia regularly provide water to this day without any maintenance. The service life of an Abyssinian well of 30 years is far from the limit. In fact, the Abyssinian well provides water as long as it is in the reservoir.
And most importantly
To construct an Abyssinian well, you do not need ABSOLUTELY ANY permits, registrations, licenses, etc. Exactly as you read, your eyesight does not deceive you.
The law on the subsoil of the Russian Federation is completely unambiguous: citizens on their land have the right to extract minerals open method from a depth of up to 5 m and DRILLING WELLS FOR WATER TO THE FIRST AQUIFER, i.e. not artesian. Believe it or not, check it, but in Russia you can still do something necessary and useful without permissions, registrations, or authorities.
Note: but it is possible to plug an Abyssinian well without danger only in the Russian Federation. In most former Soviet republics it is also not prohibited, however, the TAX legislation quietly stipulates a use tax natural resources. In Ukraine, for example, they even charge for the wind if they see a windmill on the farm. And you will have to pay for the well regularly until the column with the shell is removed, the well is not plugged according to all the rules, and its decommissioning is not properly documented.
What is he?
The Abyssinian well is nothing more than a needle well, i.e. the drill string is simply in the ground, without casing. A needle hole is drilled using percussion drilling. In professional drilling, such wells are plugged extremely rarely, because It is impossible to remove the rod with the projectile from a more or less significant depth, and the penetration depth does not exceed several tens of meters.
However, when drilling to the first aquifer (geologists and miners say “well for sand”), a needle well breaks all records for simplicity, cheapness and efficiency. Therefore, in professional speech, the needle well and the Abyssinian well have become synonymous. You can also find the expressions “tube well”, “driving well”; this is still the same Abyssinian well for sand, or more precisely, for first water.
How is it built?
The construction of an Abyssinian well is very simple, see the figure on the right. Designations:
- upper clamp with axles for pulleys;
- pulley;
- rope;
- reinforced concrete frame;
- lower clamp;
- drill string;
- Norton drill rig.
How to drill?
Sand drilling is possible both exploratory and confident. In the first case, it makes sense to purchase a factory-made set of equipment, it costs 6000-8000 rubles, see fig. lower right. The point is that the drill and string can be removed from the well and reused. The well turned out to be empty - we are trying in another place.
If, for example, on neighboring plot If there is already an existing well 20-50 meters away, then for one-time sinking the equipment can be made yourself from available materials. Its main features will be described below.
Actually percussion drilling Norton drill is a little heavy, but it’s elementary simple:
- The projectile is placed in a pit, or hung on a tripod, or simply driven into the ground with a sledgehammer.
- Insert the first rod, put the headstock, woman and upper clamp on it in turn. The clamps on the rod are tightened tightly.
- They thread the ropes into the pulleys, pull the woman to the top, let go of the ropes, and so on over and over again.
- As the column deepens, the clamps are rearranged and the column is extended with further rods.
What to drill with?
As already indicated, you can make a set of equipment for drilling a needle well yourself, as long as the farm has one and a half dozen meters of pipes with a caliber of at least 80 mm, if you intend to use submersible pump. The caliber of domestic submersible pumps is never less than 76 mm (3 inches).
If you are sure that the water needs to be raised no more than 7 m (see below), you can install a top vacuum pump. Then you can get by with any pipes, as long as they don’t bend during excavation.
The structure of the drilling rig is also discussed above, so let’s focus on the drill string and its constituent drill rods. Here and below, for brevity and clarity, when we talk about the diameter of the pipe, we mean its outside diameter. If we talk about the caliber of a pipe, then we mean its internal diameter. But for devices lowered into the pipe, the caliber will be their outer diameter.
In professional drilling and in factory kits, the rods are connected with special couplings that allow assembly and disassembly of the column. For one-time penetrations, larger caliber pipe scraps welded to the rods with a skirt can be used as couplings. The rods must be assembled into a column with their SKIRT UP, as in the picture. Otherwise, the skirt may get caught on something, or soil will get into the gap. Then the penetration will be slower and more difficult, and the column may also disconnect. In this case, you will have to leave it in the ground and make a new drill with rods.
Therefore, drilling the Abyssinian well homemade equipment can be recommended only if you are completely sure that there is water.
Where to drill?
How can you gain such confidence? Shouldn’t you walk around with a vine or a “magic frame”? Dowsing, by the way, is not a myth, although it has not yet received a complete scientific explanation. Power cable at a depth of 0.7 m open field found by 8 out of 10 people who pick up a frame for the first time. The author of these lines twice found with a frame the location of an electrical breakdown in the wall. But searching for water requires a special natural gift and great experience, so let’s turn to more accessible methods.
Where does water happen?
The best indicator of the availability of water is its known sources: wells, springs, springs or key ponds, barrels. If there are such people for half a kilometer in the area, then you will be 80% with water. But the river is not an indicator; its channel in this section may be transit.
A less reliable indicator is vegetation. Good indicators the presence of subsoil moisture are moisture-loving plants with deep roots: reed, nettle, burdock, hops, coltsfoot. You need to look for them in the hollows in the dry season; preferably lower along the general slope of the area.
How long to drill?
The depth of the aquifer in a given specific place determined by an aneroid barometer. Its length is 760 mm. rt. Art. or 1.05 MPa corresponds to 10.3 m of water column. Let's explain with an example.
Let's say there is a well nearby with water at a depth of 5 m. The aneroid near it near the ground showed 755 mm, and in your yard - 753 mm. Atmosphere pressure It changes nonlinearly with height, but when it changes within small limits, it can be considered 1 mm. rt. Art. equal to 1 m of water. Art. Then you rose 2 m from the well to yourself, and you are 7 m from the ground level to the water. This is in excess of depth, because... Aquifers generally follow the folds of the terrain.
If there are 2-3 lying around in the backyard gas pipes, then you can try to drill to the water yourself: there are no completely free-flowing aquifers, plus there is a reserve in the level of occurrence, so the lift height is unlikely to exceed 7 m. This means that it will also be possible to get by with a cheap top pump.
Where can't you drill?
Driving wells into sand is prohibited on the slopes of ravines, cliffs, and steep hillsides. Here, even a small withdrawal of soil water can disrupt natural drainage, creating the risk of landslides.
Also, you cannot drive a well closer than 15 m from a barn, poultry house, powder closet or compost heap, closer than 30 meters from cesspool or a manure heap, closer than 300 m from a cemetery, barnyard, poultry farm. If in the vicinity there is a city landfill (landfill), industrial dumps, sewerage basins, chemical or sensitive (secret) production, then they should be no closer than 3.5 km.
Note: an ordinary well cannot be dug closer than 15 m from residential or outbuildings, but this is not for sanitation reasons, but out of fear of soil subsidence. No drawdown from the Abyssinian wells has been noted anywhere, so it can be driven even in the basement, as stated above.
How to drill correctly?
So that the Abyssinian well gives water good quality, the well's flow rate was stable and the well itself did not dry up quickly, drilling should be stopped when the spear touches the waterproof bed of the aquifer, see fig. At the same time, while the water seeps down to the bottom, it will be properly cleaned, and seasonal variations well flow rate will have almost no effect.
Determine when to stop drilling by the rate of penetration. Upon reaching the aquifer, it increases noticeably, and when the spear penetrates the underlying clay, it falls again. This is where it's time to stop.
Is there water already?
Upon the expected achievement of the aquifer, in order not to continue to beat the woman in vain, if the reservoir turns out to be empty, you need to check the presence of water in the well. This is done with a mannequin - a piece of pipe welded at one end with a diameter less than the caliber of the well. The decoy is lowered into the well on a cord.
Note: It is necessary to check the well for water with a snail, because... there may be quicksand on the way to the aquifer.
When can you drink?
A “fresh” well initially produces cloudy water. It becomes transparent after an hour or a day, depending on the admixture of clay in the sand. This water can already be used for irrigation. Water is considered suitable for drinking based on the results of analysis at the SES. It is not necessary to explain the origin of the sample (1.5 l), it is enough to pay a small amount, quite officially, to the cashier according to the receipt order.
How to choose a pump?
To raise water more than 7 m or for refilling, you will need a pumping station. Don’t be alarmed - this is not a building with humming units and a man on duty at the control panel. A household pumping station is carried out of the store in hand. It consists of a submersible pump, an electric cable to it and a ballast. Hose required length will have to be purchased separately.
All household pumping stations provide a pressure of at least 45 m and a flow rate of 20 l/min, but the price ranges from 4,000 to 15,000 rubles. What's the matter?
The ability of the pump to pass solid particles of a certain size through itself without loss of performance. Structurally, the same “Aquarius” costs about 5,000 rubles for a 5 mm thick surface, and 13,000 for a 25 mm thick one.
The size of suspended particles in an Abyssinian well is considered to be equal to twice the diameter of the holes in its filter. That is, if 5 mm holes are drilled, then the pump needs to be placed on a 10 mm solid surface, and a “steep” one will be no better.
Why do you need a bailer?
Zhelonka, or bore-zhelonka, is a drilling/cleaning borehole tool for loose soils. Having plugged an Abyssinian well, especially at the dacha, it is highly advisable to acquire a bailer with a caliber of 4-5 mm less, especially since it is not difficult to make one yourself, see fig. For what?
A very reliable Abyssinian well can become filled with clay if there are long breaks in its use, especially if the soil is alluvial or moraine, as in Valdai. They clean it with a bailer: they throw it into the well on a rope, then pull it out and shake out the suspension.
The size and accuracy of the bailer is not critical; it is enough to approximately follow the proportions according to the drawing. The bailer differs favorably from other cleaning equipment for wells in that it does not require a rigid rod for use.
The most common pipe for the Abyssinian well, very cheap, the service life of which based on wells operating for more than 50 years is very long. With constant use of a well in the Moscow region, water completely fills the entire internal space of the pipe and in the absence of contact with oxygen, corrosion forms only with outside pipes. It is more likely that a stainless steel pipe will begin to leak sand than a black pipe will rust. The only drawback of this pipe is its progressive corrosion during long periods of downtime.
Also very common, a little more expensive than black, it has especially become widespread in the last 20-30 years.
Today, SNiP does not prohibit the use of galvanized pipes in internal cold water supply systems, but when laying underground water supply Protection (cathodic, anodic) SNiP 2.05.06-85 must be carried out: Protection of pipelines from corrosion.
Corrosion of ferrous metals most often comes down to their oxidation and transformation into oxides. Corrosion iron pipe described by the simplified equation
4Fe + 3O2 + 2H2O = 2Fe2O3 H2O
Hydrated iron oxide Fe2O3·H2O is rust.
If you do not provide appropriate protection to the galvanized pipe of the Abyssinian well, then gradually, over many years, hydrogen ions (water) will approach the iron cathode and discharge, accepting electrons. Hydrogen atoms, when formed, combine to form an H2 molecule. The ion flows will be separated, this facilitates the electrochemical process. The zinc coating will be subject to dissolution (corrosion), while the iron will be protected for the time being. Zinc protects iron from corrosion. All of the above broth, which contains zinc, lead, magnesium, cadmium, antimony, and arsenic, will negatively affect your health for years.
Let's assume that you were provided with cathodic protection of the Abyssinian well, but what about the one in which holes are drilled and a tip is welded, threads are cut on the pipes - all these processes were accompanied by heating, during which a large amount of harmful substances. By the way, heating a galvanized pipe for drinking water supply is prohibited by SNiP 3.05.01-85. In the USSR, to prevent pipe heating, thread rolling, rather than cutting, was used.
The best and most expensive material for an Abyssinian well in the Moscow region has become widespread recently. In favor of this material, we can say that most of the dishes in your home are made of stainless steel.
Polypropylene and HDPE pipes
It is quite difficult to make an Abyssinian well from these materials, so they are not widely used. There is a SanPiN for this material, negative reviews he does not have.
