How to clean the well yourself - a description of the methods. Cleaning wells from silt and sand: causes of clogging and cleaning methods How to clean a borehole pump

One fine day, you discovered that the well is not able to work in the usual mode? It is a pity that there are no "eternal" sources for water supply, is not it? Do you suspect that its mechanical clogging has occurred over time and want to fix the problem on your own, but do not know where to start and which option to choose?

We will help you deal with the problem and choose the best option. Let's tell you what other methods of self-cleaning exist - the article discusses the best methods applicable at home, both for removing blockages in an equipped well and in working out.

After all, troubles can lie in wait at the drilling stage. Until the casing pipe (working string) is installed, the soil can collapse into the working, clogging it.

And we also picked up photographs demonstrating the procedure and tools for performing self-cleaning. For clarity, expert video recommendations are attached - so cleaning the well with your own hands will be within your power.

  • Strictly adhere to the chosen drilling technology. Carefully monitor the tightness of the casing and the integrity of the filter.
  • Immediately after completion of drilling, flush the source until clear water appears.
  • Protect the well from surface water intrusion and contamination, cap. As a temporary solution, simply seal the top of the casing.
  • Before starting operation, it is correct to select and install the submersible pump at the required height, necessarily taking into account the flow rate of the well.
  • It is advisable not to use a vibration pump to supply water.. Vibrating in the casing, it, depending on the type of soil, to a greater or lesser extent provokes the penetration of sand into the well or contributes to siltation of the adjacent soil. A cheap and simple vibrator can be used for a short time, it is needed for permanent work.
  • The well should not stand idle without parsing water. The ideal mode of operation is the daily pumping of several tens or hundreds of liters of water. It is provided if people permanently live in the house. If this is not possible, you should regularly, at least once every 2 months, pump out at least 100 liters of water from the well.

The correct arrangement of the well is the key to its longevity. It is necessary to install a special head on the casing pipe, which seals it and serves for reliable installation of equipment

Possible causes of clogging

It is worth mentioning the types of clogged wells, this will help identify the causes of problems and determine how to do it right.

No. 1 - sand penetration into the casing

"Sanding" is a problem encountered in shallow sand wells where the aquifer is located in a sand and gravel layer. In a well-arranged well, sand penetrates into the casing in a small amount.

If the performance of the source decreases, and grains of sand appear in the water, one of the following occurs:

  • Sand penetrates from the surface - the cap, the caisson is not airtight.
  • The filter is irrationally selected, the cells are too large.
  • The integrity of the filter has been violated.
  • The tightness between the casing sections is broken. The thread is not fully tightened, the welding is of poor quality, corrosion has "eaten" a hole in the steel casing, mechanical damage to the plastic one.

It is not possible to eliminate leaks that appear inside the well. Fine sand constantly breaks through the filter, but it is also easier to remove it, it is partially washed out when the water rises.

Worse, if coarse sand penetrates the well, over time the source may “swim”. That is why you should pay special attention to the quality of installation and filter selection.

No. 2 - siltation of a non-operating well

Over time, the smallest particles of clay, rust, calcium deposits, sedimentary rocks accumulate in the thickness of the soil in the filter zone.

When their number becomes too large, the pores in the aquifer and the cells of the mesh (perforated, slotted) filter become clogged, it becomes more difficult for water to penetrate through the mine shaft.

The flow rate of the well falls, it “silts up” up to the complete disappearance of water. In a source that is used regularly, the process is slow, stretching over decades. Without regular pumping, a well can become silted up in a year or two.

If the well is cleaned of silt in a timely manner, without waiting until it completely dries up, it is likely to give the source a "second life". Water will be supplied in sufficient volume to supply a private house.

Cleaning the well by pumping with a vibration pump will not help to cope with serious silting of the soil, but it can remove a large amount of sand that has penetrated the casing.

True, provided that the well is shallow. When climbing over 30-50 m, the performance of the vibropump drops noticeably, depending on the model. Please note: only a pump with a lower water intake is suitable for us.

In order for the vibrator to actively suck in impurities, it should be lowered almost onto sandy deposits, raising only a few centimeters above the bottom. As the sand is removed, its level will decrease, and the pump must also be lowered.

The time of continuous operation should not exceed half an hour, periodically the pump should be turned off for 10-15 minutes to allow it to cool.

If the sand contains pebbles larger than 3-5 mm in diameter, they will be pushed under the membrane, preventing the flow of water. The membrane can only be released by lifting the pump to the surface.

The cleaning method with a vibrating pump is not always effective and takes quite a long time. But it is simple and almost does not require physical participation of a person.

Method #2 - p rinsing with a pump from the surface

It is possible to effectively remove fine sand, rust and turbidity from the casing pipe by supplying water to the well from the surface.

In order not to turn the site into a swamp, it is better to organize flushing in a closed cycle. Especially if there is no source of clean water nearby (we do not recommend flushing the source with water from an open reservoir).

To do this, stock up on containers containing a volume of fluid equal to the full (from bottom to top) capacity of the casing.

The flushing liquid will be circulated between the well and the tank by means of a pump. Contaminants will accumulate at the bottom of the tank, they will need to be removed periodically. The pump will need a powerful one, you can add chemicals to the solution.

For example, orthophosphoric acid, which dissolves layers of rust and calcium deposits.

Do not forget that the acid is quenched with baking soda, and after applying chemicals, the restored well should be pumped for at least 6 hours.

At the wellhead, instead of a head, a nozzle should be installed to direct the backwash into the tank. It is possible to carry out flushing and not in a closed cycle, pumping water into the well from a neighboring water supply.

In this case, there is no need to "bother" with the tanks, but you should provide a drain for dirty water and make sure that it does not fall back into the casing.

Water is fed down with a hose, the length of which should be enough for it to lie directly on the bottom. The surface rinsing method cleans the filter quite effectively.

The first pump, located at the top, delivers the flushing fluid to the bottom of the well, raising the impurities. The second, submersible centrifugal, pumps water with sand and silt to the surface.

To extract contaminants, you can use the pump that is installed in the well, it will not have to be removed or even lowered below the suspension point.

The main thing is to lower the hose supplying water to the very bottom, passing it in a narrow casing pipe next to the submersible pump. It must be understood that if there is sand and small pebbles in the water, the pump will be subject to increased wear.

Method #4 - Sand Extraction with a Bailer

The method of cleaning a well from sand using a bailer is very effective for removing a large amount of sand, pebbles and compacted deposits of small fractions from the casing.

However, it is almost useless if you need to clean the filter and the soil adjacent to it from silt. Bailer - a piece of steel pipe with a length of a meter and a half with a valve on one side and a lever-eye for a cable on the other. The design is quite simple - do it yourself.

The valve is a heavy steel ball held by a washer that is attached to a threaded connection.

1. Sandy.
The most commonly used type of wells. The means of purification of water coming from the ground is sand and fine gravel laid on its bottom.
The main disadvantages of sand wells:
- the water level and its chemical composition are often subject to seasonal changes;
- the formation of silt on the surface of the filter and the walls of the well, which reduces the inflow of water and its quality;
- the need for regular cleaning of the well.

2. Artesian well.
Wells of this type reach the depth of aquifers, which are located at the level of waterproof limestone rocks. Usually the depth of artesian wells is 50 meters or more. Since the costs of building an artesian well are significant, but at the same time it is capable of providing water in significant volumes, it is advisable to undertake its construction by collective forces for several houses.

There are two types of wells:
- with a straight trunk of the same diameter throughout the depth; several pipes of the same size, welded together, are installed in the trunk; the deep pump sinks to the very bottom, which prevents intensive silting and simplifies cleaning the well with a vibration pump.
- with a filter having a diameter smaller than the size of the barrel; a pipe with small holes in the lower part is placed inside the main one.

Causes of well silting:

1. Errors in the construction of the well, when the aquifer is not reached.

2. Insufficiently intensive use of the well, as a result of which water stagnates in the wellbore, particles of clay, silt, and rusty delaminations from the pipe occur.

3. The use of vibration pumps with top water intake or rotary pumps, which are only immersed to 8-10 m, does not allow pumping water from the depth of the well.

4. Filters in the form of pipes with a smaller diameter than the main pipe do not allow the submersible pump to be lowered to their upper edge. As a result, the filter is quickly clogged with settled particles, and water flow is deteriorating.

Any well sooner or later (depending on the intensity of use, the quality of the filters and the pumps used) requires cleaning. Naturally, one should not wait for its complete clogging, it is better to carry out preventive treatment of the source of moisture from time to time.

Methods for self-cleaning a well.

1. Using a bailer.
Reliable, albeit time consuming, way.
The bailer, fixed on a cable, descends to the bottom of the well. Then it is raised about half a meter and abruptly released. Under the influence of its weight (considerable), it falls, biting into the silt. The valve at the bottom of the bailer opens and the agitated sediment enters. When the bailer is raised, its valve closes and the collected sludge is taken out. The operation should be repeated several times until the bottom of the well is completely cleared. To facilitate the procedure, it is recommended to build a gate, fixing it on a tripod, it will reduce physical exertion.


2. Using a vibration pump equipped with a nozzle.
This method allows you to clean the well from sediment without any special physical costs. It can be used in wells of any type, especially in cases where, due to the small diameter of the pipe, it is impossible to use a conventional vibration pump. A strong hose is put on the water intake of the pump (type "Kid"), which in turn must be fixed with a clamp to the body of the unit. For the reliability of the structure, experts recommend inserting and fixing a PVC or metal pipe of the appropriate length inside the hose.


Attach a weight to the end of the hose to prevent it from floating up. The pump equipped in this way is lowered into the well until the nozzle touches the silty bottom. Then it rises slightly (by 5-10 cm) and turns on. Water with agitated sediment is sucked in by the pump and fed outside. The well is quickly cleared. The only drawback of this method is the rapid wear of the working valve due to the ingress of large sediment particles into it. If necessary, after completion of work, the rubber piston of the pump is replaced with a new one.

3. With two pumps.
This method involves the use of two pumps - deep with a lower water intake and self-priming (Kama type). The cleaning process is slower, but the pump is not clogged with large sediment particles. Outside, next to the well, a large container (barrel) with a volume of about 200 liters is installed. A small container (for example: an old bucket) with a mesh bottom is attached to the top of the main tank. The end of the hose from the self-priming pump is lowered into it. A load is attached to the end of the second hose from this pump and lowered into the well. Then it is necessary to lower the deep pump into the well so that it is at a distance of 10-30 cm from the level of the formed sludge. To do this, the unit is lowered to the stop, and then raised to the required height and fixed. Installation is ready.


First, the deep pump is turned on, which draws water from the well into a large container to the top. If there is not enough water from the well to fill the barrel, it should be added. Then the second pump is turned on, which pumps water from the barrel into the well, causing the lower layer of water to mix and the silt to rise. Since the end of the hose is immersed in a small container with a mesh, silt particles will not fall back into the well. As it is cleaned, the end of the hose supplying water to the well should be slightly lowered to the bottom. If too dirty water comes out of the well, then in order to avoid clogging of the deep pump, you need to raise the end of the supply hose. The cleaning process usually takes 2 hours.


4. With the help of a vibrating deep pump.
This is perhaps the easiest way, although more time consuming. An existing vibratory deep-well pump and a small, heavy dowel or trident made with metal fittings are used. The ripper, tied on a thin cable or strong cord, is lowered into the well. By sharply raising and lowering it to the bottom, the sediment is loosened and mixed. Then a pump is lowered into the well, which pumps the turbid water out until clear water flows. And the pin works again. Thus, in several steps, the bottom of the well is cleared of silt.

If the cable to which the pin is attached does not interfere with the operation of the pump, then you can not remove it. Simultaneous operation of the ripper and pump will speed up the work. In this case, the pump must be located above the pin.

I accidentally read your recommendations for cleaning the well. Some commentary on the article: Babies and Brooks (all vibrational) - this is more often a quick death for a well. "Barrel" - the concept of the resulting development in the drilling process. The pipes lowered into the trunk are a "column". If they end (begin) with a filter, then "filter column". If the filter is lowered inward, i.e. smaller diameter "column with a filter in the sweat". The filter part has in its design a sump for sedimentation of sludge, sand, etc. In no case should the pump be in the filter zone, and it is also not recommended in the sump. (The word sump speaks of its purpose), etc. The best way to clean the filter zone of wells and settling tanks is Airlift. If the column is up to 125mm, a D-25mm PE pipe is taken, loaded, lowered to the "bottom" and connected to a compressor with a capacity of 0.7 m3 / min (more is better). The compressor must have a working pressure of at least the height of the liquid column in the well (otherwise PYH). Do not apply pressure sharply (otherwise PYH filter), etc. etc. Good luck.

It can no longer function in the previous mode, then do not panic. After all, there are no “eternal” sources of water supply and it is possible that a mechanical clogging of the well has occurred. In this article we will tell you how to deal with this problem on your own, without involving specialists. Cleaning a well from silt and sand is not as complicated as it might seem at first glance. And if you arm yourself with our instructions, then there will be no problems at all!

How to avoid well clogging? Important Points

So, we found out that sooner or later, all well owners have problems. Of course, if the aquifer dries up, then deepening of the development or drilling of a new well will be required, which can hardly be considered easy and cheap procedures.



It is a completely different matter if the well is clogged - this can even be avoided if it is operated in accordance with all the rules. How to extend the life of the water source on the site?

Table. Well operation rules.

ruleShort description
Make sure that the casing is tight and the filter is intact.
Ideally, several tens / hundreds of liters need to be pumped out every day, and this is not a problem if people live in the house all the time. Otherwise, try to pump out at least a hundred liters every two months.
After drilling, immediately flush the source until clean water appears.
It is better to refuse the vibration pumpThe fact is that such a pump, vibrating, will contribute to the silting of the soil or the ingress of sand into the well (to a greater / lesser extent). It is better to use a centrifugal pump for this purpose.
Install a cap for this, a caisson. Alternatively (but only temporarily), seal the top of the casing.
Do this even before the start of the operation of the well, taking into account the water flow rate, and install the device at the desired height.

Note! If you follow all these recommendations, you still will not be able to prevent clogging of the well. But you can delay the problem, achieve the maximum resource for efficient use.


Why can a well become clogged?

To understand the causes of the problem and choose the appropriate cleaning method, you need to familiarize yourself with the types of clogging.

Reason one. Sand got into the casing

This is a common problem in shallow sand wells where the aquifer is located in a sand and gravel layer. If the well is properly equipped, sand will enter the casing in minimal volumes.

With a decrease in well productivity and the presence of grains of sand in the water, the problem may be:

  • ingress of sand from the surface (due to leakage of the caisson, cap);
  • broken tightness between casing elements;
  • incorrectly selected (with too large cells);
  • violation of the integrity of the filter.

It is impossible to eliminate leaks inside the well. Fine sand, constantly penetrating through the filter, is easily removed (especially since it is partially washed out when lifting). But when coarse sand gets in, everything is somewhat more complicated, the well can simply “swim” over time. That is why it is necessary to choose a filter and mount casing elements with special attention.


The second reason. Unused well silted up

Over time, particles of rocks, rust, clay, and calcium deposits accumulate in the ground near the filter. With an excessive amount of them, the filter cells and pores in the aquifer are clogged, and therefore it will be more difficult for water to enter. The flow rate of the source decreases, it silts up to the complete disappearance of water. If the well is used regularly, then this process slows down and can take decades, and if not, then siltation may take one to two years.

In the case of timely cleaning of the well from sludge (that is, before the water disappears completely), the source can most likely acquire a “second life”. Water supply will be maintained in sufficient volumes for the residents of the house.


How to clean a well yourself. Available methods

There are three main principles that can be used - pumping, flushing with circulating water, blowing with compressed air. As for the methods, there are several more.

Method number 1. Pumping with a vibration pump

A simple, but not always effective way. good for cleaning, while not recommended for regular use. Plus, the vibrator is undemanding to water - it easily copes with sand and even small pebbles. Of course, the check valve can fail because of this, but it costs a penny and changes in just a few minutes.



Note! The cost of such a pump is several times lower than that of a circulation pump, and even if it fails completely, the financial damage will be insignificant.



Disassembly of the vibration pump

For cleaning the well, such models as "Baby", "Brook" are suitable. Such cleaning will not cope with serious silting, but it will help to get rid of a large amount of sand. But only if the well is shallow - if the rise is more than 30-50 m, the productivity will noticeably decrease. Also remember that only a pump with a lower water intake will do.


During operation, the pump must be switched off regularly for about 15 minutes, continuous operation should not last more than half an hour. Note that this method, despite its simplicity and minimum human participation, is not always effective and will cost some money.



Master Class. How to clean a well with a vibration pump

Step 1. A vibration pump with a lower water intake is being prepared. In our example, the device is being slightly modified.


Step 2 The extreme nut is twisted at the tip of the pump, after which a metal bracket about 15 cm long is installed on the center. It is well attracted by the nut so that it does not jump down. Thanks to this design, the silt at the bottom of the well will be better shaken up.




Step 3 A hose and a cord are also connected to the pump (it will lower and rise by means of the second pump).


Step 4 The pump with the hose is slowly lowered to the bottom of the well. It must be lowered to the full depth, before contact with pollution.


Note! There must be some water in the well. If not, pour on top.


Step 5 When everything is ready, the pump turns on and light up and down rocking movements begin to be performed. The device should be located near the very bottom of the well, the bracket, screwed at the beginning, stirs up the silt. The pump picks up dirt and throws it out.


Step 6 The sludge is constantly agitated by means of a pump. The process may be delayed, which will indicate large deposits in the well, but the result is worth it.


The pump is periodically pulled out, its inlets are inspected. If required, they are cleaned.


Step 7 During the day of work in our example, we managed to remove several buckets of rust, sand and other contaminants.


Method number 2. Surface water supply

To remove turbidity, rust and fine sand, pumping from the surface can be performed. It is desirable to organize the process in a closed cycle, otherwise the site can be turned into a swamp. Water from an open reservoir should not be used, therefore it is necessary to prepare containers, the total volume of which is equal to the full volume of the casing pipe.


The fluid will circulate between the tank and the well thanks to the pump. Dirt will settle at the bottom of the container, so it will have to be removed periodically. The pump must be powerful. If you want, add chemicals to the liquid - for example, phosphoric acid, which will dissolve calcium deposits and rust. Remember that acid must be quenched with baking soda; moreover, after its use, the well needs to be pumped for at least another six hours.

Instead of a head, a nozzle is installed at the mouth of the source, which will direct the washing into the container with a reverse flow. The cycle, by the way, may not be closed - water can be pumped from the neighbors' water supply.

Down the water is supplied by a hose, its length should be enough for it to lie right on the bottom. This method allows you to effectively clean the filter.

Method number 3. Use of two pumps

If the depth of the well is more than 50 m, then it is problematic to clean it using the previous two methods. However, if two pumps are used at the same time, the washing efficiency can be significantly increased. In this case, deep and surface aggregates will be required. The first will pump water with impurities to the surface, and the second, located on top, will supply the washing liquid to the bottom.




You can remove pollution using the pump that is in the well - you do not need to remove it or lower it below the suspension point. It is only necessary to pass the supply hose in the casing pipe about to lower it to the very bottom. And remember: if there are small stones and sand in the water, the pump will be subject to increased wear.



Method number 4. Using a bailer

This method, which involves the use of a bailer, is effective if you need to remove a lot of pebbles, sand or fine compacted deposits. But if the filter or the soil next to it needs to be cleaned of silt, the method will be almost useless.

Who does not know, a bailer is a steel pipe 1-1.5 m long, on one side of which there is a lever-eye for a cable, and on the other, a valve. Extremely simple design, if you wish, you can make a bailer with your own hands.




A massive steel ball acts as a valve, which is held by a washer fixed to the threaded connection.

Water must be completely pumped out of the casing pipe, after which the bailer drops sharply to the very bottom. When hitting the sand, the valve will open and a certain amount of contaminants will get inside. Then the bailer rises, is cleaned of sand, after which the procedure is repeated more than once. It is advisable to wield the projectile together, it is more convenient to lower / raise it using a tripod with a winch or a block.


Note! The bailer can be made with your own hands, purchased or rented. You need to work with it carefully, especially next to the filter (there is a risk of damaging the thin mesh).



To remove the last few centimeters of dirt, it is worth using another method in which there are no shock effects.


Situation.
The well is 15 years old, depth 45 meters, water with iron, water column 6 meters.
Over the past 5 years, there has been a gradual decrease in production and a decrease in depth of about 1 meter or more.
Obviously it's time to clean up.
At first I tried to gel with a manual bailer - a pipe with a valve, weight 10 kg.
The bailer gains very little sediment, a couple of glasses.
Hard and very slow.
I don’t want to beat with a heavy powerful bailer, I’m afraid to break through the bottom, the water will go away.
Result:
- The well recovered in depth and flow rate to the same level as I started to operate it about 8 years ago.
- About 3 buckets of impurities (sand, small stones, rust in nodules) were extracted from the well.
- In addition, for about 8 hours he pumped out turbidity and dirty water with his own pump after cleaning, installed in its place.
- I cleaned it with a homemade device, made according to the idea from the Internet, according to the principle of a cyclone.

The idea is this:
The cleaning method was prompted by a drawing from this article:
http://usadba-kirov.ru/infrastruktur...skvazhinu.html

Since the "baby" cannot pump water with sand (although everyone does it, it eventually ends - overheating or complete wear of the valves, they are rubber), then you need to separate the water from the sand, do not pump this water to the top, but put in a circle in the well for loosening.
For example, the dirt that I had in the well cannot be lifted by any vibrator, there is a lot of it and it is very heavy.

Based on this idea, I made my iron construction - for real.
This is a pipe of 1.5 meters, in which a vibration pump and a container for collecting dirt are installed according to the "cyclone" principle.

This design is lowered into the well, the pump is turned on and collects dirt from the bottom of the well into the tank. It takes all of 15 minutes.
After that, we raise it - shake out the dirt and lower it again.
My design is gaining dirt about 3 - 5 liters.
Moreover, it picks up large stones and even dissolved silt - a cyclone is a great idea, it separates even the smallest particles of dirt.

What is bad is the severity of the design. But the attempt to make all this out of plastic failed. The installation should sink well under its own weight. Loosening takes place by the installation itself, since the vibrator transmits vibration to the pipe, and in addition, I welded three legs for loosening and stability at the bottom.
It turned out a water vacuum cleaner.

How is this better than bailers?
The main thing is that you do not need to hit anything, throw anything, injure the filters, the casing and the water-bearing layer.
Lowered - waited 15 minutes - raised - shook out the dirt. Everything is simple.
This method picks up much more mud in one lift than a manual bailer.
Lifts everything from rocks to dissolved silt. At the end, when the coarse dirt was lifted, the plant came full of slurry of dissolved fine dirt.
Below is a drawing of an idea and my solution in hardware:

The well is convenient in that it is an excellent alternative to centralized water supply, such a source of water on the site solves problems with irrigation and the use of life-giving moisture for household needs. But it is necessary to carry out preventive work from time to time so that the well is clean and the system is working properly, so many cottage owners are thinking about how to clean the well with their own hands without spending a lot of money on it.

If the water pressure has become weaker, this is the first alarm signal. This is usually followed by a brief stagnation with a characteristic gurgling and subsequent ejection of cloudy water, and then the system stops working.

Do-it-yourself well cleaning begins with determining the cause of the breakdown. There can be many reasons for this: problems often arise during irregular operation, errors during drilling and construction. Aquifers can change their direction - in this case, the cause will be natural.

If the structure does not have protective mechanisms, much more debris will enter the wellhead. The reason may be lack of maintenance or poor pump performance.

There are two main types of wells (with a filter and a straight hole) and three main ways to get the well working: flush it, pump it, or blow it.

It is more convenient to clean the water intake with a straight shaft - the equipment can be lowered to the bottom, thereby eliminating the risk of rapid silting. But with irregular operation, any well will become clogged sooner or later.

Scheme of a well device with a mesh filter. Many summer residents recommend using filters rather than chlorinating the water. But sooner or later, any well will need cleaning, so we choose a convenient method based on its characteristics.

The most affordable independent way to clean a country well from sand and silt is pumping.

Method #1 - Using a Standard Vibration Pump

If you have a conventional pump or a special one that is used for contaminated water, you can pump out a mixture of silt and sand, and debris with small stones. A pump is installed at the bottom of the well, and all debris deposited at the bottom enters the nozzle and is sucked up by the pump. Clean water must also be passed through the pump from time to time. If the case becomes very hot, it means that you need to let the equipment rest. It is possible to clean the well with a standard vibration pump of the "Kid" type, if it is shallow - the pump will lower by a maximum of 40 meters.

The pump is at the bottom of the well, water with impurities is sucked into the nozzle and thrown out. Clean water is passed through the pump from time to time to keep work surfaces clean. For the safety of the equipment, it is better to turn it off once or twice to avoid overheating.

Method # 2 - cleaning the well with a bailer

If the well is slightly clogged, and at the same time shallow in itself, a bailer can be used. In other cases, its application will be ineffective. If the depth is within 30m or more, you will also need a winch, and this method of cleaning will require considerable effort from two strong men.

Bailer - a piece of pipe on a cable with a mesh in the upper part and a hole in the bottom. It sinks to the bottom, then rises to a height of 0.5 m and drops sharply. Water is drawn inside, inside the cylinder there is a ball of metal, which after a couple of seconds rises, and then falls and closes the hole. Such a cycle of raising and lowering is repeated three or four times, then the bailer is raised and cleared of sand. To make it more convenient, you can use a tripod. About 0.5 kg of sand enters the cylinder at a time, so by cleaning in this way, you can find out how quickly the well becomes clogged.

Photo and diagram of the bailer device. Reviews about this method of cleaning the well are both positive and negative. For some, this method of cleaning seems to be very time-consuming and inefficient, someone only uses it. If you can make a bailer yourself, such cleaning will not require extra expenses, and this is already a plus

Method # 3 - mechanized cleaning

The most effective way for deep wells is mechanized cleaning. The best option is to use two pumps working in pairs.

A deep well pump equipped with a lower hydraulic intake is located at the bottom of the well. He lifts up the water with mud and silt. The pump, working with it in pairs, supplies water to shake up the deposits under pressure from the tank. For cleaning to be really effective, shake the water outlet hose and make sure that the amount of contaminants is not too large, if their concentration in the water is very high, overheating and even equipment failure may occur.

The equipment must also be selected correctly, the selection depends on the depth at which the water is located. Vibration pumps are used if the water depth is more than 10 meters.

Mechanized cleaning of the well with the help of a deep pump and a pump that works in pairs with it is recognized as the most effective way. Much here depends on the correct selection of pumps, so it is better to consult with specialists before cleaning.

Method # 4 - cleaning with a fire truck

To clean the well, you can call a fire engine. Using a fire hose and strong pressure, a well can be cleared in ten minutes. But this method is expensive and dangerous, filters and system components can be damaged from strong pressure. This method is recommended for severe pollution.

Method # 5 - using an airlift

How to clean a well in the country from sand and silt using an airlift? The method consists in using the law of Archimedes. What exactly is a well? This is a container of water. A water-lifting pipe is placed in it, into the lower part of which compressed air is supplied by means of an air compressor. A mixture of air and foam is formed in the pipe. The water column presses from below on the riser pipe - the process begins, it must be controlled so that the water in the well being cleaned does not run out.

Since the bottom of the pipe is located almost on the sand, sand with water rises and is absorbed by the riser pipe. The task of the person involved in cleaning is to monitor the water level in the well.

Cleaning with an airlift pump is also an effective way. Compressed air is supplied under pressure, at the bottom of the pipe, silt, water, small stones rise, are absorbed by the pipe and are pushed to the surface

As a rule, the wells in the areas are shallow, and a standard vibratory pump or bailer is suitable for cleaning. If the depth of the well is significant, you can try the mechanized cleaning method. When using a fire truck hose, cleaning the well will be very fast, but it is expensive. Unfortunately, this method often leads to damage, and this entails additional costs. If the main source of water in your country house is a well, choose a cleaning method that is convenient for you and periodically clean it so that there are no interruptions in the water supply, because water in the country is the main condition for a comfortable stay.
