How to clean the well from the sand: an overview of the main

Contamination of the well with sand and silt occurs gradually, but there comes a moment when the water begins to change color and smell. This suggests that the bottomhole zone requires urgent cleaning.

We will tell you how to clean the well water from sand and silt with your own hands.

Well cleaning

With zhelonka

This is a fairly effective way to clean shallow wells. With a large depth, the laboriousness of the process ceases to justify its use, and then other methods of cleaning are resorted to..

For work using a special projectile - zhelonku. This is a length of pipe between about 500 and 700 mm, which on one side is closed by a grill, and on the other hand, has open access and a check valve. Can be used as a leaf valve and ball valve, but the use of the ball more efficiently.

When the projectile falls to the bottom of the well, it crashes into the silt and sand that lies at the bottom. Under pressure from the sand, the ball rises, but due to greater density, it immediately falls into place and closes the hole in the washer. A certain amount of dirt has time to get into the bile.

Then the process is repeated until the shell is full. Then it is removed from the canal and cleaned. The process is repeated again and again until the bottomhole zone and the bottom zone is cleared of silt and dirt.

For work it is convenient to use a tripod and winch, but you can do without them.

For your convenience, we have compiled step-by-step instructions for using this method:

1. Extract from the casing deep pump. If the well is used constantly and regularly, it will not cause difficulties, if the pump is concreted with sand, then it is necessary to wash it with a compressor;

We take the shell and bind to its end a steel or nylon cable of the required length (well depth plus a margin of 2–3 meters);

1. The tool is inserted into the chute and throw. The cable must be folded on the ground with rings, and the lower ring starts from the free end (the principle of laying resembles laying of a fishing line before throwing cargo into the depth);

1. If a winch is used, it is better to unwind the cable, after fixing the projectile, and to shift it according to the fishing line principle;
2. We throw the shell once, then extract and see how full the vessel is. So we determine the number of strokes until the tool is completely filled;

1. We clean the well until the shell stops filling with silt, sand and particles of rock.

When the projectile starts to raise only the water, even if it is muddy, you can lower the pump and pump until the clear water flows.

Note! For more effective cleaning, you can use a ruff, which is suspended on a cable and moved up and down in the area of ​​the filter. The ruff bristles will clean the well filter from various deposits and efflorescence, which will then deliver to the surface of the shell.

Using vibrating pumps

Now we will tell how to clean a well from sand in a more modern and effective way. The price of such cleaning will increase somewhat, since for operation you need a pair of pumps: one for pumping water into the well, the other for pumping.

For your convenience, we have compiled a step-by-step instruction:

1. Remove the pump from the well;

1. We take the hose, attach the load to its end and lower it to the bottom of the well;

1. The upper end of the hose is connected to the water supply pump, and from the pump we supply the hose to the barrel. The end of the hose for taking water from the barrel is lowered into a 10-liter eggplant with a lot of holes in the body; we wrap the material itself (filter cloth, geotextile or fine mesh);

1. In the well we lower the vibration pump on the cable, just above the bottom. The hose from this pump is directed to the barrel, where the filter-box is already installed;

1. We collect in the barrel tap water and turn on the feed pump. As soon as half of the water is gone, turn on the vibration pump. The system will start to drive the water in a circle, extracting along with it the sludge and sand washed by the pressure of the feed pump;

1. We work until the water from the vibrating pump becomes transparent.

Note! Make sure that the water in the barrel does not fall below the level of the water intake hose with a filter, otherwise the pump may burn.

Conclusion

As we have seen, it is possible to perform the well cleaning process yourself. For successful work, you should simply follow the instructions in the instructions, following the safety precautions.
