Well cleaning: a review of effective methods

When may need to clean the wells with your own hands? Any well sooner or later begins to lose its original performance in connection with the silting or technical breakdown of the elements of the siege pipe.

Technical failures may be caused by moving the ground or improperly flushing the well with high pressure water. However, most often the reason for the decline in indicators is silting, which predominates in wells with irregular (seasonal) use.

Before you start cleaning the source, you need to find out the reason for reducing the supply of water or its pollution. Based on the data obtained, wells are cleaned and repaired independently or with the assistance of professional workers from various companies..

The main reasons for the decline in well productivity

The main reasons for the decrease in water volumes or its pollution can be:

• filter clogging;
• filter breakage due to ground movement;
• silting during prolonged idle time of the source;
• errors when drilling and installing a siege pipe;
• irregular maintenance;
• The installed well filter is significantly smaller in diameter than the main casing, as a result of which the pump does not reach the bottom of the well and this accelerates the silting process.

For uninterrupted supply of clean water should be regularly audited design.

• dismantle maintenance equipment from the wellhead;
• check the depth of the source and compare it with the passport indicators to determine the amount of sludge;
• check the filters of the water system of the well and the operation of all its mechanisms and aggregates;
• determined with the method of cleaning or repair according to the data.

After diagnosing and identifying the causes of clogging, you can accurately determine whether it is worthwhile to call the masters or you can solve the problem yourself.

If, as a result of the inspection, a malfunction of the service equipment was identified, then with the presence of a tool, it can be replaced independently. In case of damage to the casing or the depth filter, it is better to call a specialist to correct the problem.

To repair the part, you need to examine the device.

The main methods of cleaning when silting

Some activities can be done by hand.

• cleaning the well with pressurized water;
• compressed air blow;
• pumping pump;
• Sink cleaning (photo).

Do-it-yourself well cleaning with water that is supplied from the surface under pressure is the most common method because it has high productivity and does not require special equipment or skills.

Rinsing the well with water under pressure

To perform this operation, you will need:

• submersible well cleaning pump;
• centrifugal pump for water supply under pressure;
• water tank from 200 liters;
• a hose with a metal tube at the end (5-6 meters longer than the depth of the well);

It is advisable to install a container with water near the mine. A metal tube is put on one end of the hose to prevent the hose from bending when it stops at the bottom.

The second end is connected to a centrifugal pump, which will supply water from the tank through a pressure filter. The submersible pump will take the dirty water from the well, and feed it back into the tank, creating a looped system.

The essence of the method lies in the fact that a centrifugal pump creates a large pressure, which, coming out of a metal pipe, breaks up the sludge and other bottom sediments, and the submersible pump pumps out the eroded sediments to the surface.

In this case, the well can be cleaned using a deep-well vibrating pump with a lower intake, since it will additionally break bottom sediments, which will significantly speed up the cleaning time.

Disadvantages of this method

If the pressure pump is too powerful and creates a very strong jet pressure, this can destroy the filter. If this work is carried out by professional teams, they take into account the parameters of the installed filter and the degree of its wear as a result of corrosion, on the basis of which the safe water pressure is calculated.

In order to avoid such damage, it is better to choose a not very powerful pump. With a little water pressure, the time for cleaning increases significantly, but you will be sure of the integrity of the bottom filter.

We carry out the work independently.

It will cost you much cheaper than the cost of cleaning wells with the involvement of qualified professionals with their capacity. Yes, and the farm is useful for storing water supplies with drip irrigation.

It is important to remember that the submersible pump, when working with a silted fluid, is under heavy loads and can fail. In order to avoid breakage, it is recommended to use a cheaper pump when cleaning or regularly remove the existing one and rinse it in clean water.

Tip! It is advisable to purchase such a centrifugal pump, the performance of which will be equal to the capacity of the submersible pump, in order to balance the filling of the feed tank.

A filter must be installed on the centrifugal pump's suction inlet, as small stones or coarse sand may be caught in the pump rotor, causing the blades to jam or break.

Conclusion

This flushing instruction may be useful to you if you have a shallow mine, with a depth of 10 to 30 meters. For deeper artesian wells, you will need to attract qualified specialists with special equipment and tools.

Cleaning deep wells requires certain knowledge and skills that can be learned from the video in this article.
