Well today is a fairly common source of water in the private sector. The cost of its development is much lower than drilling a well( even the simplest - for limestone), and the quality of water is no worse. But to keep it at a consistently high level, this artificial reservoir needs systematic care.
The recommended frequency of maintenance activities is at least once every 1.5 to 2 years .If the source is on a site where no one lives permanently, which means that the well is operated from time to time, then the terms of maintenance should be reduced in half.
However, in some cases, it is advisable to carry out "unscheduled" work to clean the well, as the decrease in water quality can be caused by a number of circumstances completely beyond the control of the rules of operation and maintenance of the artificial reservoir. How is this determined?
Signs of excess fluid contamination
- Unpleasant odor coming from the source.
- Water turbidity, change in color and taste.
- Lowering the level.
- Appearance on the surface of the plaque in the form of a film.
- Characteristic mucous deposits on the inner walls of the well.
The reasons for the pollution of the reservoir are more than enough - the appearance of cracks in structural elements, ingress of foreign bodies, damage to the layer of waterproofing and a number of others. The task of this article does not include a detailed consideration of all factors that adversely affect the quality of the liquid. We will understand only how to properly organize and clean the well with your own hands.
Operating procedure( mechanical method)
It is clear that without cleaning the walls, it will not be possible to thoroughly clean the walls. The question is, how convenient will it work? In terms of comfort, it is better to empty the well, and then start cleaning. But it takes time to pump out the water, and the mucus( mud) in the upper part of the log( barrel) can be in time to dry up. This will significantly complicate the work.
If the well is shallow, then, as an option - to install a ladder( though it will have to be prepared long enough), and as the water level drops, while cleaning the walls and inspect them for obvious defects( cracks, formed shells and so on).The advantage of this technique is that, in parallel with the mechanical cleaning of the wall, it is possible to thoroughly wash off dirt residues.
With a sufficiently large depth of the "mine", the descent into the well and its processing is also carried out in parallel with the pumping of water. But the worker does not use a ladder, but special slings, which are held by the winch.
Further, the bottom of the reservoir is cleaned, as well as the filter element of the autonomous water supply system( if it is installed).If a bottom filter is installed, it is dismantled, fed out, and there it is flushed or updated material( depending on the type of cleaning layer).
The final stage is complete disinfection of the barrel.
For work on cleaning the "mine" you will definitely need an assistant!
Firstly , in order to ensure the safety of the worker.
Secondly , someone after all needs to lift up( and then lower) a bucket of mud. If you work alone, the cleaning process will take a long time.
What is needed?
Now it becomes clear what may be needed for such an event:
-
Bilge pump. - Devices for descent into the well( ladder, safety belt, winch, slings or strong rope).
- Tools - spatula, trowel, hard brush( better metal), bucket.
- Materials( if necessary minor repairs) - sealant, CTC solution + "liquid" glass and the like.
- Items of equipment - boots( rubber), headgear( helmet, in extreme cases, an old hat).A gas mask - no matter what the skeptics claimed, but he certainly will not be superfluous. Even if the concentration of gases in the "mine" and a small, then a long stay in such a well must "hail".Therefore, it is better not to take risks.
if necessary
- Clay "castle" is being restored( restored).
- A new floor filter is being equipped.
What to check in advance
Gassiness level .It is the increased concentration of gases in the wellbore that is one of the most common causes of the death of workers. Such a device, as a gas analyzer, is not a household appliance, therefore, rarely anyone has it. You can check the safety with a candle flame. If it does not change when lowering into the mine, then everything is normal. A change in the level of the "tongue"( attenuation or vice versa, an increase in the torch) is a clear indication of the accumulation of gases.
Council
Quite often there are recommendations for cleaning wells using drainage pumps. It should be understood that such work, although effective, but only in relation to water - it does not save the walls from the raid. Therefore, the best quality treatment of the internal part of the well is achieved only by hand.
