Turbidity of the liquid occurs due to the ingress of a large number of various substances into the source. They can harm human health or damage pumping equipment. Why there was a problem, you can find out after passing the samples for analysis to the laboratory.
The causes of cloudy water from wells are biological, chemical and mechanical. Their features are listed in the table:
The reasons | signs | Cleaning methods |
Biological | The presence in the water of the remains of rotting plants, the smallest algae, microorganisms, bad smell. | Mechanical method, filtration of water at the outlet of the well |
Mechanical | The presence of sand, clay and other insoluble sediments in the water | mechanical way |
Chemical | The presence of salts, chemical elements, gases in water, which is determined by chemical analysis, an unpleasant odor | Well water filtration |
Causes of biological contamination of the well:
To obtain full information about why in the well cloudy water, take fluid samples to the sanitary and epidemiological station.
When dirty water appears from the well, first of all find out the cause of the problem and eliminate it, and then proceed to clean the mine. If after all the procedures the quality of the liquid does not improve, use filtration systems in plumbing system. To reduce the amount of dirt that causes cloudy water, the following methods are used: cleaning the well with a bailer, flushing and pumping with liquid. Consider the cases in which each method is relevant.
The most common bugs to fix are:
The fixture is made from a pipe that fits freely inside the casing string. A gap of 2-3 mm is allowed between the walls. At the bottom there is a hole with a valve through which the soil enters the tool. The damper (or ball) will keep the soil from falling out when the bailer is raised to the surface.
There is an eyelet at the top of the tool. A rope is attached to it to lift the projectile with mud to the surface.
The cleaning procedure is carried out in the following sequence:
If the mine is not deep, and sand and other solid impurities are the cause of the loss of transparency, the dirt can be pumped out with a vibrating pump. Products of this type have less power than centrifugal, but are cheaper. This fact should be taken into account, because grains of sand and pebbles can damage the pump.
Perform the following operations:
The pump has a small capacity, so the cleaning procedure can take a long time.
For pumping it is allowed to use centrifugal pump high power, designed to work with thick liquids. It is allowed to use a device that is used in the operation of the well. The vibration pump is not capable of lifting water from a deep well, so it is not recommended to use it in this case.
The operation will require a lot of technical fluid, so install a large tank near the well and fill it with water. Place the pump nearby. Install the suction hose in the container, lower the other to the bottom of the source.
After turning on both devices, the centrifugal pump will begin to pump out the dirt into the prepared container on the surface. In it, heavy particles will settle to the bottom, and the liquid will again be sent to the mine. Work stops when the pumped out water does not become light. Turn off the pump and pump all the contents out of the well several times.
If the walls of the shaft and the filter are strong, flush the source with a pump. To do this, lower the hose from the pump to the bottom of the well and turn on the device. A powerful jet will mix the dirt with the water and lift it to the surface. Thus, not only sand and clay are removed from the well, but all organic matter. To reduce water consumption, direct the pumped liquid into a large tank, where the dirt will precipitate, and then re-pump it into the well.
What to do if muddy water comes out of the well - look at the video:
Almost every summer resident or owner of a private house has to face the problem of water pollution in a well. If the well is punched in accordance with all the rules of hydraulic engineering, from the moment it is put into operation, the water intake will produce a relatively clean flow for three to four years. But as the reservoir ages and sandy-silty deposits accumulate, muddy water that appears in the well in spring can become an unpleasant surprise at the very wrong moment. Before jumping to conclusions, spending energy and money on inefficient cleaning methods, you must first figure out why the well is dirty water.
It is clear that the reason for the appearance of turbidity in the water is a violation of the integrity of the filtration system of the bottom cushion and side walls, due to which pollutants got into the water intake cavity. Cleaning or flushing the well can be done within a day or two, but hard work will be useless if you do not find out why dirt accumulates in the well and do not eliminate its source and cause. There can be several ways and methods of dirt accumulation in a well:
This is one of the more severe cases. What to do? Most likely, it will be necessary to do a major overhaul of the well, look for a place of seepage and restore the tightness of the gate. Often, the owners of the well are perplexed why the pipe could rust if the well is five years old at the most. Corrosion of metal goes on constantly, but it makes it especially strong increased content salts, hydrogen sulfide accumulation and even a power line running nearby.
Advice! Overhaul best done under the guidance of experienced professionals who have diagnostic tools and are able to accurately determine the well recovery technique.
In other cases, repair and cleaning of the well can be done by hand, this work is not the easiest, but if the water intake restoration technology is followed, it is quite realistic to provide a home water supply system with clean water for several years to come.
Some experts believe that it is easier not to do flushing or repair procedures, but to drill a new well, from which, after washing and pumping out the dirt, clean water can be taken for a long time. The method is known, but it is not possible to rearrange the well in all cases.
This option is possible, but only if the cause is not traces of manganese-iron ores, due to which the water can become contaminated and cloudy over a sufficiently large area. Wherever you decide to make a well, rusty water with a high salt content will still run out of it. First of all, water pollution will occur at shallow depths, so the nearest well or shallow wells will be the first to suffer.
For the treatment of water intake, several simple methods are used:
Advice! Before flushing the water intake, raise submersible pump and evaluate the condition of the strainer-mud filter. By how much dirt has stuck, and how water is coming through the filter, you can judge the degree of contamination and choose the most appropriate treatment method correctly.
In some cases, pollution can come from swamp water, which flowed through the veins of a drying spring into aquifers. In this case, it will be necessary to flush the well once or twice with an acid solution and periodically pump out the contents of the water intake, you will have to do this while water comes from the well with a marsh smell and organic matter. Every couple of months you need to do a water test.
You can remove dirt from the water intake in two consecutive procedures. Initially, it will be necessary to pump out the water and remove the accumulated sand with clay and fine gravel from the bottom of the water intake. The easiest way to do this is with a groove - a steel cylinder with a hole and ball valve. The groove is lowered with a cable to the bottom of the water intake, raised to a height of a meter or half a meter and dropped vertically onto a layer of dirt, after which the tool is lifted up. If you do the driving correctly, then 300-500 ml of dirt will go with each lift.
After every five lifts, the level of dirt under the pump intake decreases, but there is still a lot of dirt in the cavity. If you try to pump out the water, it will still go dirty, so after the groove you need to flush.
In the very simple version vibrating pump can be used. Due to vibration, most liquid mud rises from the bottom into the water column, and the cleaning process is faster, but there is a danger of collapse of part of the arch. Dirty water is lifted up, settled and poured into the pipe, forcing the flow to go in a circle.
For gentle flushing, the scheme below is used.
A hose with a load or a rod is lowered into the wellbore. It should go almost to the very bottom, not reaching only 4-5 cm. After that, the submersible pump is lowered, a gap of 30-40 cm is made between the bottom and the filter intake window. clean water from the tank is pumped under pressure into the hose, the liquid washes and picks up silt, dirt and even small pebbles and goes through the submersible pump up to the collection tank. Periodically, the submersible pump is removed, the filters are cleaned and sent back.
If it is not possible to use a vibration pump or an additional hose with a load, then the dirt is lifted from the bottom with an ordinary two-inch pipe with a tip sharpened in the form of a trident. The tool is made heavy, but such that it can be pulled out of the mud with a cable. The pipe is lowered to the bottom and a layer of mud is loosened in the water. After that, the submersible or vibration pump is lowered and the dirty water is pumped out.
It is clear that it is best not to wait until the water intake becomes clogged, or dirty water flows. The cleaning procedure is best done after a long break in the use of the well, in early spring, after the departure of the flood and the lowering of the groundwater level, or in the fall. In this case, the water quality will be guaranteed to be high throughout the summer or winter period time.

Often, owners of country estates complain that muddy water comes from the well. The problem is real, unpleasant, but it must and can be dealt with. First you need to figure out why muddy water comes out of the well, and only then draw up an action plan and start fixing the problem. Experts divide all the causes of this phenomenon into: mechanical, chemical and biological. We propose to understand each of them in more detail.
Most often, turbidity occurs due to mechanical causes, this includes:
Dirty water from a well can go due to biological reasons, because microorganisms invisible to our eyes are present everywhere in the air, in water and even underground. Naturally, they leave the products of their vital activity, which is why silting, flowering, water contamination with bacteria occurs. An effective way to fight is prevention. If timely remediation is carried out, then problems can be avoided. It is imperative to install filtration equipment, periodically clean and replace it, and in some cases even clean the column with a bailer.
Turbid water in a well can appear due to chemical reactions, man-made disasters, oil spills and emissions from chemical plants. Of course, it is absolutely impossible to use water from wells located in places of chemical damage. Only after a certain time will the aquifer be able to restore the supply of a clean, usable resource. Dirty water from a well can be evidence of a reaction to the oxidation of iron. This can only occur if iron and oxygen are present in the water. To fix the problem, you need to create a completely sealed barrel and install an iron filter.
Turbid water from the well - causes and what to do if muddy water comes out of the well. The main causes of cloudy water in the well. What needs to be done to get rid of muddy water in the well. Various ways well cleaning, their features, advantages and disadvantages. Turbid water from a well can significantly spoil the quality of life in a cottage. After understanding the reasons for this situation, you can decide what to do if muddy water comes out of the well.
Turbid water from a well can flow for various reasons. All of them can be divided into two groups:
The first group of causes is due to the vital activity of various bacteria and microorganisms. These include the following types of water turbidity:
A common cause of cloudy water are leaks in the aquatic environment. chemical reactions. They are caused by technogenic water pollution by runoff from industrial enterprises, sedimentary waters. If the tightness of the well is broken, all these substances seep into the aquatic environment and cause its pollution and turbidity. A laboratory analysis of the water will help determine the cause.
In most cases, cloudy water in the well is obtained due to mechanical reasons, which include:
After you eliminate the cause of the cloudy water environment in the well, the structure itself also needs to be cleaned. There are several ways to clean them:
The first method of well cleaning is performed in several stages:
The fastest and effective method well cleaning is the use of a vibration pump. The only negative is the inability to determine the distance to the bottom. However, this is not required in all cases.
The cleaning procedure is performed as follows:
The speed of cleaning by this method significantly exceeds the cleaning efficiency of the previous method. However, please note that a vibrating type pump will not be able to lift large, heavy contaminants. Also, very rapid wear of the valve of the unit is observed.
If there is muddy white water in the well, and the structure itself has a considerable depth, then The best way cleaning - mechanized. For this, two simultaneously working pumping units. Wherein:
The cleaning procedure takes quite a long time, since small liquid pressures are used. Work is carried out in the following order:
Cleaning with a deep unit is quite time-consuming, but not very long in time. To do this, you need to do the following:
Often, in order to determine the cause of cloudy water in the well, it is necessary to perform a laboratory analysis, which will help to accurately identify the type of pollutant. You can order such an analysis in our laboratory. To do this, you need to call us by phone. When calling, you can clarify the cost of the check, which depends on the number of indicators checked.
