Why does not water come from the well? What to do if a new well gives little water

Well construction on the site is a priority for the summer resident. The problem of low-quality water is widespread everywhere. Why is muddy water in the well in the area? The case may be in drilling errors, natural factors and poor-quality equipment. It is necessary to understand everything in detail.

Mechanical causes

Installation of equipment with disturbances and improper operation leads to turbidity of water. If the well is located at a depth of less than fifteen meters from the surface of the earth, then the likelihood of impurities of mud and clay is high. The presence of these substances can also be explained by the presence of a reservoir near the site. The water in the well will turn out to be bad because of the weak filtering abilities of the soil.

Unreliable cased pipes may not isolate the layer of perch. It will seep on the outside of the pipes and trap impurities that will enter the aquifer. Ground displacement and improper installation of casing string lead to cracks on the casing. Through the ruptures of equipment from the well is turbid water.

Impurities fall if the gravel cushion is washed away. The bottom of the future well is lined with gravel, which acts as a filter. When the integrity of such a coating is violated, the particle flow enters the water. Because of this, the filter and pump quickly fail. If the pump is too low, at the filter itself, it will suck in the dirty water located at the very bottom.

Vibration-type pumps are often used to produce water at suburban area. Use on sandy and clay soils leads to clogging of the system and the appearance of turbid water from the well. In the worst case, it is necessary to clean the entire system.

A sudden turbidity of the water signals a filter damage. He can not hold the liquid, and it enters the well. In this case, only the overhaul of the entire system will help.

Chemical causes

The presence of various compounds in the soil explains why there is a dirty water. If you drill next to the industrial zone, then this source can only be used for technical needs. Care should be given to the place of arrangement of the new well. Various man-made disasters, as a result of which hazardous substances fall into deep layers of soil, make it unfit for water extraction. Probably, it is necessary to go on other site.

In the water layers there is always a lot of iron. If the casing is damaged, it causes the water to become cloudy. Air entering the system will oxidize the iron and lead to rusting. The sealing of the barrel will make the water transparent.

Biological reasons

Pathogenic microorganisms live in water and are able to penetrate into hydraulic structures, forming turbidity. Viruses and bacteria appear in non-deep wells. To get drinking water, you need to drill a hole to a depth of at least ten meters. It should not be allowed to get water from other aquifers into the source, causing it to grow turbid. When changing the color, you need to do a sanation.

Siltation

Sealing of the bottom is the most common cause of turbidity of the well water. Elevated concentrations of suspensions and reduced head pressure indicate the beginning of the siltation process. The reasons can be different:

• saving materials and erroneous calculations. Cheap grid and dusting, as well as inaccurate measurements quickly lead to siltation, the formation of dirty water, the failure of filtering systems;
• violation of technical requirements  when installing the system. Water coming from the pump has a weak flow rate;
• low water consumption. In this case clay and rust from the pipe will settle in the well. Regular fence and high flow reduce the risk of turbidity to none;
• incorrect installation of the pipe. The pump is silted if the pipe is not submerged in the aquifer and not in the slightly water-bearing layer. Such work is a marriage; In due course it is necessary to drill a new well.

Reduction in pressure is not always associated with silting. Bad water  is a sign of depletion of the water layer.

Methods of cleaning

To choose the appropriate method, you need to understand why the water from the well becomes turbid. The first cleaning is carried out immediately after drilling to remove dirt and debris from the pipe. They can flow for more than a week, but without this process the system will not function properly.

For cleaning use a compressor and several pipes connected together. Their diameter should be smaller than the diameter of the well. Pipes are inserted inside, weighting the top of the structure. An air adapter is then installed, the compressor is turned on and directed so that the air goes into the well. It should be borne in mind that this is a dirty work: because of high pressure  the waters from the bottom will flood everything around.

Minor clogging in the wells is eliminated with a bailer. It is a cylindrical object that draws out liquid. Many make the device themselves, using inexpensive and easily accessible materials. Beforehand, all equipment is extracted from the well. The pipe with the valve systems sinks to the bottom. The creeper goes to the bottom and breaks the accumulated deposits under the influence of its own gravity. Then it is extracted and cleaned. The procedure requires repeated repetition.

For effective cleaning  use two pumps at once: self-priming and deep. This method eliminates clogging devices. Next to the well, a deep reservoir is placed, for example a barrel, and a small receptacle with a mesh bottom is attached to its base. The hose of the self-priming pump is lowered into it, and the other end of the hose is lowered with the load to the bottom. The deep pump is immersed so that the hose remains at a distance of 30 cm from the contaminants. It is turned on and the barrel is filled with water to the brim. The self-priming pump works to shake the sludge. After that, the deep device starts to feed dirty water. Thanks to this method, the well can be cleaned in a few hours.

Self-priming pump

Submersible pump will cope with dirty deposits. Before starting work, the water from the well is poured into the allotted space. The procedure requires a pump that is capable of sucking small stones. He is tied to a strong cable, lowered to the bottom and turned on. It is necessary to control the process in order not to miss the moment of full water pumping. For work will suit vibrating pump. His work is similar to the submerged one.

Submersible pump

For cleaning, chemical reagent. It is effective if the water is cloudy due to iron salts and calcareous deposits. At the bottom pour acid, pre-pumping all the water. The outer part  Wells are tightly closed. After two days, the liquid is removed. You can use the source for household needs several months after the procedure. Until then, muddy water drained from the well is used only for irrigation.

The chemical method of cleaning is best left to the extreme case, when the rest were ineffective.

Before cleaning the well, it is best to go to the laboratory to do a muddy water analysis. He will precisely establish the cause of turbidity. When choosing the method of cleaning, one should proceed from the financial situation. To solve all problems it is desirable to rely on the opinions of specialists who always tell what to do.

In order to extract water from the well, it is necessary that the water in it at all was. And for this you need to know, how to find water for a well  ; Usually searches are conducted in two ways:

1. Specialists examine maps of the depths of the occurrence of aquifers, are guided by their own experience and the experience of neighbors around the site. All these methods give an answer with some probability.
2. The exact answer you can get only with the help of an exploratory well. Only in this way can you save yourself from unnecessary waste.

Consider water at the bottom of the well, at the very end casing  - this is far from the most useful and enjoyable occupation. Everybody wants to see how the liquid from the bowels of the Earth beats the key from the tap in your house. Such a problem will help prevent quality equipment: filters, pump and caisson.

If the water is gone, first inhale the air with a full chest and calm down. We need to find out the reason why there is so little water.

The reasons can be different, for example, there is a possibility that a dozen of your neighbors decided to repeat your experience and acquire their own source of moisture, while the water simply was not enough.

Another possible cause may be siltation. This is especially likely if it has been idle for a long period of time. No less possible causes may be foreign objects or casing leakage. Finally, a pump or filter system could fail.

You can try the following manipulations to cope with this problem:

1. cleaning by pressure of water;
2. cleaning with the help of various specialized chemically aggressive agents;
3. hydraulic shock (the so-called effective, but rather unsafe procedure, which can cause damage to the casing).

However, you must remember that before you take any action to fix the problem, it is best to first understand its essence. Sometimes, for this purpose, a study is conducted, during which specialists lower the video camera into the well, carefully examining its entire trunk.

We give the possible reasons in descending order of probability of the problem:

1. The most likely cause of the lack of water is the fact that the filter is not in the aquifer.
2. Another possible outcome is the situation where the filter clogs. This is considered an oversight by the drillers.
3. But the fact that the filter is clogged with particles of the water-bearing horizon - it's just a failure.
4. Probably the source of the water is not deep enough.

All of the above defects can only be corrected by the efforts of the drilling rig.

1. There is little water, because the pump is not energized. Perhaps you forgot to turn it on or someone broke the wires. Probably, the voltage in the network is not high enough for trouble-free operation of the pump.
2. The pump is too old or broken.
3. The pump does not cope with the operation with the current hydrodynamic characteristics.
4. Pipes, through which water from the well enters the house, is clogged or frozen.

All of the above defects are easily corrected after the elimination of their cause.

1. Perhaps you have not had time to "swing" the well. For more information, how to properly swing a new well  you can find on the Internet.

Arrangement of a well under water for a private house, cottage or a bath is the main task, which any homeowner will have to solve. One of the frequent problems is the appearance of a sharp smell, sediment and turbidity of water. In this case, there arises quite a reasonable question: why from the well is turbid water and how to solve this trouble?

Often during operation hydraulic engineering structure  a serious problem may appear: drinking water  acquires a characteristic turbidity. To choose an effective method of troubleshooting, first you need to find out the possible causes of such a phenomenon.

Muddy water from the well can go for many reasons. Conditionally they are divided into three categories:

• biological;
• chemical;
• mechanical.

Causes of Biological Origin

Pathogenic organisms and products of their vital activity fall into the environment - in air, soil, water, including in hydraulic engineering structures.

Muddy water from the well appears as a result of:

• reproduction of pathogenic microflora, siltation and flowering. This occurs in the spring, when various bacteria and microspores of plants enter the water source;
• contamination with substances of organic origin that penetrate the aquifer from the soil.

What to do in case of biological water pollution? An effective way of eliminating the problem is the prevention and sanitation of a water source. In some cases it is recommended to install new or replace old filtration units for disinfection of the well, as well as deep cleaning of the mine.

Causes of chemical origin

A serious reason why there may be muddy water in a well can be various chemical processes:

• contamination of a water source by chemical elements as a result of accidents and disasters of anthropogenic nature;
• oxidative processes with a high iron content in the aquifer. Oxidation is possible only in case of partial or complete depressurization casing.

If the hydraulic structure is located near the industrial zone, such water can not be used even for technical needs. Complete cleansing of the aquifer from chemical elements requires a long time, so it is better to choose a more favorable place for the arrangement of a new well or well.

To eliminate the processes of oxidation of iron in water, it is sufficient to strengthen the casing and install a bottom purification filter.

Causes of mechanical origin

Sometimes the water from the well becomes cloudy when drilling or misusing pumping equipment. The mechanical reasons for the appearance of the turbidity of the aquifer are:

• washing of the cover layer in case of violation of the installation process of the casing string of the structure. An insufficient layer of gravel dumps will not prevent the entry of limestone and sand particles into the well;
• breakage or siltation of the bottom filter. This is due to improper use of the equipment or excessive clogging of sediments;
• deformation, destruction of the mine as a result of ground displacement, improper installation of water pipes and their fixation elements;
• installation of pumping equipment of a vibrating type - it can lead to deformation of the inner walls of the column and break the tightness of the joints.

If the dirty water appears when the gravel cushion is washed out, the problem is solved by filling the protective layer.

If the bottom cleaning filter fails, the only correct solution is a quick replacement with new equipment.

If the water from the well is cloudy as a result of the damage to the column, the problem can be solved by restoring the leak-tightness and washing the structure, in some cases by equipping the new hydraulic structure.

Eliminating the reason for the appearance of turbid water in the well, it is recommended to perform thorough cleaning of the hydraulic structure. Effective methods of cleaning include:

• cleaning with bailer;
• cleaning with a vibrating and deep pump;
• mechanical cleaning.

Method of cleaning with a bailer

The purification process using a bailer is carried out in stages:

1. At the bottom of the well, a trough is lowered. Then it rises to a height of 45 cm with a sharp dip on the bottom.
2. The cycle consists of 4 lifts / dives. Why is it necessary to do this? To fill the bailer with water by half the volume and clean it of silt deposits on the bottom of the structure.
3. The filled bailer is removed to the surface, thoroughly cleaned and lowered to the bottom. The procedure is repeated up to 3-4 times.

Method of cleaning with a deep and vibrating pump

For high-quality cleaning of the hydraulic structure it is recommended to use borehole pump. The works are carried out in the following order:

1. The metal baking powder on the cable is placed in the shaft. It is used to loosen silty sediments that have accumulated at the bottom of the structure.
2. At the bottom sinks pump equipment  and the pumping of water is carried out until the mine is completely cleared. After the turbid water is evacuated from the well, it is possible to extract the equipment to the surface.

1. The hose is fixed to the pump body. A load is attached to the bottom of the hose to prevent it from floating when immersed.
2. The hose sinks to the bottom, then rises to a height of 10 cm, after which the pump starts.
3. The equipment provides a high cleaning speed, but is not suitable for extracting heavy contaminants, which lead to rapid wear of the valve. If water comes from the well with clay, this method of cleaning is not recommended.

Mechanical cleaning method

If a turbid, almost white water is flowing from the well, and the well is drilled to a depth of over 10 meters, an effective method of purification is mechanical. For the work, two pumps are used - with a deep fence and a self-priming type. The cleaning procedure is as follows:

1. A tank of up to 220 liters is installed near the facility. A funnel with a mesh bottom is fixed to it.
2. The hose is immersed in the tank, through which the liquid will go to another pump.
3. A hose with a cargo is lowered into the shaft. At a height of 35 cm from the bottom, a deep pump is installed.
4. Water is supplied to the casing to clean the silt deposits. Hose immersion is performed as the well is cleaned.

Often homeowners can not determine for themselves why the water from the well can become cloudy. In this case, it is recommended to perform a water analysis in the laboratory to identify possible causes of the change in the color of the water.

With the reduction of the water head in the tap or in the absence of well water from its consumers (sink, shower, washer, for example) before calling the masters who drill turnkey wells, make sure that the source of the problem is outside the building.

P checking the water pump

Do the following 3 steps:

• Make sure that in each tap the water head is equal. If water does not come from one, then most likely it is necessary to clean only the filter grid of the mixer. Before checking the water pump, make sure that your pump has an auto-protection system from "idling", without which the pump can fail in the absence of liquid.
• Check the water head and the quality of the liquid at the entrance to the building, that head that is fixed up to the filters or the battery pack. If the equipment is installed according to all the rules, it is usual to leave the crane to diagnose problems and to drain the fluid from the system in the absence of heating in winter.

To check the water head, take the hose that reaches to the closest to the tap sewer. To determine the result of the test is correct, observe the water pipe for at least half an hour at a good pressure. If the water stops coming in 30 minutes, stop checking.

What conclusions can be drawn?

In the case when the water head at the entrance to the structure is sufficient for half an hour and remains unchanged, one should look for the reason for the poor water supply to the tap in the house. And the reasons can be in:

purification filters;

pressure switch valves;

pipes;

battery-charger

mixer.

To diagnose a "weak link", it is enough to apply to a plumber, but better to a master who installed cleaning and plumbing equipment. In the case when water comes in portions or with inclusions of silt, sand, the source of troubles with water supply should be looked for underground. If the well water is not supplied at all, most likely the pump does not function. So, it will not be possible to diagnose the system further until the pump is dismantled and inspected.

Do not rush to lift the pump out of the well, make sure that power is supplied to it from the building. For this purpose, disconnect the power supply cable from the pump from the power supply module. And apply power to 220 volts directly. Has the liquid come in? Then call the master automatic equipment: it is because of it that water is not supplied. If a direct connection to the standard socket of the pump cable is not foreseen, invite a specialist who is qualified to work under voltage.

Well and water carrier: who is to blame and what to do?

After making sure that the problem of water supply outside the house, make sure that the water carrier from which water is supplied has not changed since the completion of the well. To do this, it is easiest to address neighbors with a well of this depth and find out if they have problems with water supply. If there is no water supply from the neighbor well, most likely, you will have to look for a new water-carrier and order it.

Arriving at your vacation home, You found that you were left without water, although you are absolutely sure that the pump is working properly. This means that there is no water in the well - what to do? It is necessary to find out the cause of this unpleasant phenomenon. There are several reasons for this.

Possible causes of lack of water in the system

1. A sharp increase in the intensity of the use of the aquifer, for example, as a result of the emergence of a large number of new consumers in the territory. Usually, the situation is faced by owners autonomous water supply, using a well as a source for sand.
2. Siltation of the well is the accumulation inside the casing of solid particles, the layer of which over time can block the access of water through the filter.

Possible causes of siltation of the well:

• a long break in the operation of the system;
• errors in design or installation;
• error in pump selection;
• corrosion processes in casing string, the result of which was the loss of its tightness.

More often it is typical, but with a very long break in operation can appear in the limestone.

Methods for restoring the system

Having established, why there is no water in the well, what to do the specialists decide, proceeding from the reason:

1. If the reason for the insufficient capacity of the aquifer, then the only solution is the solution drill a new well for water  , and preferably on limestone, so that water is always there. In this case, you should contact the services of the drilling company.
2. In case of siltation, it is possible to restore the well. To do this, you must first make a video recording of the production pipe, which will identify all existing problems and outline a plan for their elimination. Before starting to repair the well, it is cleaned of accumulated debris. After this, they begin to eliminate siltation in its water intake part.

The following operations can be used for this:

• Bleed the air-water mixture. The jet of such a mixture is fed under pressure into the well. It eliminates silt, washing the sand off the bottom and clearing the voids of the porous rock. To obtain an effect, a pressure of the order of 10-15 atmospheres is necessary.
• Rinsing with special reagents is used if the pumping has not given the desired effect. Such dry cleaning allows to destroy sediments on the trunk of the casing and on the filter.
• Hydroburst is the strongest cleaning method. A special method in the casing sharply increases the pressure, as a result of the increased pressure of water, the blockage breaks through. This method allows you to clean even a running column, but it can lead to a disruption in the integrity of the system, if the well is old and the casing is already susceptible to corrosion.

To the question: there is no water in the well, what to do, the answer is simple - turn to specialists. All procedures for restoring the system are complex and time-consuming. They require special knowledge and skills and must be produced by professionals using special techniques. This will avoid damage to any part of your autonomous water supply system and restore its operation in the shortest possible time.
