Cleaning wells at the cottage is a necessary measure, as it allows you to refine the source of water supply, and if you have certain knowledge and skills, it is carried out independently. Properly clean the water from sand, clay and silt with your own hands is quite laborious, therefore, it is necessary to carry out such a technically complex process in strict accordance with the rules established by the regulations.

When a well needs to be cleaned

Inexperienced owners of individual sources of water supply often do not know how many times it costs to clean up and how to carry out such an event. A significant part of experts agree that aquifers need to be cleaned at least a couple of times a year.

Such measures are necessary in order to maintain the water supply rate at a sufficiently high level. Important to remember, that you need to clean and flush the well even with a good supply of water to the home. On the bottom of the well over time, sediment accumulates, which must be systematically removed. Otherwise, the filter system will become clogged very quickly and must be replaced.

Installing a new filter is an expensive undertaking, so cleaning of sludge and other contaminants should be carried out systematically.

Causes of pollution

It is important for any well owner to know and be able to correctly determine the cause of a sharp deterioration in the quality of water. Most often, you can encounter siltation of water, which is accompanied by a rapid depletion of the resource of the filter system, which does not fully cope with a significant amount of impurities and contaminants. The presence of turbid or unpleasant smelling water from foreign matter is most often the result of clogging with sludge as a result of:

  • shifts of soil layers;
  • surface debris;
  • shedding of the walls of the structure;

  • prolonged interruption and intermittent use or violations of the rules of re-conservation;
  • leaching of components from an aquifer;
  • violations of well drilling technology.

Often, pollution is provoked by the use of rotary water pumps, which can be used exclusively at a depth of not more than ten meters. To clean this type of device, you must take a vibration pump. It is lowered into the well at the very bottom gradually. It’s not possible to clean the bottom manuallytherefore, to fully remove all dirt and sand, the use of special equipment will be required that can rid the structure even of very small particles.

How to clean a well with your own hands

Cleaning the well from silt and sand using equipment

Currently, six are widely used, the most common and convenient methods that allow you to clean the well qualitatively, but the most popular options are the use of a vibration pump and compressor.

Application of vibration pump

Using the pump, it is possible to clean without physical effort, and the disadvantages of this option include the inability to determine the real bottom of the well. To carry out cleaning work, it will be necessary to use a “Kid” type vibration pump with a water intake from below, and The cleaning technology is as follows:

  • a reliable hose is mounted and secured by means of a clamp on the protruding part of the intake body;
  • another long hose or tube is installed inside the hose, followed by a secure fit;
  • the unit with nozzles is lowered into the well, after which the equipment is turned on and cleaning is carried out with a vibration pump.

After the work is completed, it may be necessary to replace the rubber piston in the pump assembly, which often fails.

Purge Compressor

The technology of flushing or purging a well with a compressor is one of the most commonly used methods, and is excellent for sand structures if it is necessary to quickly and accurately remove numerous silt and sand deposits. To pump a well in this way, you need to prepare a compressor, a long air hose and a flexible plastic pipe that enters the wellbore:

  • a pipe is inserted inside the well, which should not reach the bottom of the structure by about ½ meter;
  • then an air hose connected to the compressor starts, the edges of which should slightly protrude beyond the edges of the pipe;
  • after the compressor is turned on, with the help of a jet of compressed air coming out of the hose under high pressure, the bottom sediment is stirred up and at the same time water is pushed out.

A feature of this simple method is the fastest, as compared to using a pump, pumping of a drilled well mine.

Use of other equipment

It is possible to pump out pollution or to purge a well in a personal plot with other equally effective methods.

using the bailerThe base of the device is represented by a steel pipe and valve, in the form of a metal ball at the endThe design must be suspended and lowered into the trunk on a strong cable to the bottom, after which it rises by half a meter and sharply released. After three repetitions, the bailer should be freed from accumulated contaminants
by means of a scraper and a ruffMechanical devices for manual cleaning, which are not difficult to make yourselfA brush with a radially fixed steel cable is lowered into the well to clean the walls of plaque and dirt. While lowering the scraper, plaque is also removed from the walls, and a trap pipe is used to catch debris
by swabThe device consists of a metal disc and a rubber valveSwab must be installed at the end of the drill pipe, and when moving upward, the valve is shut off, which destroys loose rocks and cleans the holes in the filter columns
using two pumpsThe most costly option requiring a large amount of waterOne pump is used to supply water to the well being cleaned, and the second allows it to be pumped out.

Chemical cleaning

The most promising and effective to date is precisely the chemical cleaning of the well, which is a multi-stage cleaning using basic potent agents. Chemical cleaning is most often carried out with food reagents.. First of all, sorbic acid is used, as well as citric and ascorbic acids, which are natural preservatives.

The general composition of reagents for cleaning wells includes gum arabic, represented by a solid and transparent mass of plant origin. The natural components used include xanthan gum and sodium benzoate. Safe chemicals include sodium dithionite, sodium tripolyphosphate and sodium hexametaphosphate. For cleaning, you need to purchase acid and filling tanks, a well sealing device, a transfer pump, hoses with valves, instrumentation, airlift system and a compressor.

After several days of operation of an aquifer that has been chemically cleaned, a mandatory measure is to replace the fine filter in the water treatment system in households.

Features of the integrated method

Comprehensive cleaning of the wellbore contributes to the restoration of the water supply function without unnecessary time and money. The method allows you to deal with mechanical pollution, pollution with iron, hydrogen sulfide and manganese, increased rigidity and bacteriological pollution. For this purpose, special treatment systems can be installed:

  • mechanical waste removal;
  • aeration to eliminate hydrogen sulfide and anaerobic bacteria;
  • precipitation filtering;
  • stiffness reduction by ion exchange resins.

Modern filtering systems successfully combine high performance and affordable cost.

How to clean a well filter

To date, two options are practiced, allowing you to clean the well filter from accumulated deposits:

  • mechanical cleaning involves the use of a special metal ruff equipped with a water supply system;
  • the chemical method consists in pouring a reagent, dissolving deposits, followed by pumping with clean water.

Within a few days after using chemical reagents, it is strictly forbidden to use water for food purposes and for cattle feed. Water can be withdrawn only for the purpose of carrying out irrigation activities and for auxiliary needs.

How to clean a well with a pump

In recent years, wells and wells have been used increasingly as the main source of water for summer cottages and garden plots, as well as cottages and suburban households, so only proper water treatment and timely cleaning work will allow you to get high-quality drinking water.

    Yes it's science fiction

    I'm sorry, but I think you are wrong. I can prove it. Email me at PM, we'll talk.
