Well - one of the most traditional sources of water supply at the preservation areas. Clean well water - transparent, like a tear, without outsiders and the taste. If its quality has changed for the worst direction, it is necessary to immediately beat the alarm - dirty well water can cause various diseases.
1
There are a number of reasons that lead to water pollution in the well:
the turbidity of water is most often due to the depressurization of technological holes (for example, seams or joints) and the penetration of rainflows and melting water during the off-season;
water staining in brown or greenish color occurs as a result of organic contaminants;
water darkening testifies to the rare use of the well;
changing the color of well water can also cause incorrect operation of pumping equipment.

In the first two cases, the crystal transparency will help return the water and high-quality mine repairs. When cleaning the well and subsequent repair work, be sure to follow safety:
before immersion in the well, it is necessary to wear overalls, construction helmet and swamp boots;
ideally, the well of the well need to be held in the threesome (one person descends into the mine, the second - descends and accepts buckets and the tool, the third - controls the retaining rafters and the insurance cable);
before cleaning the well, it is necessary to make sure that there is no unsafe gases in the mine (for this purpose, a bucket with a burning candle is lowered into the well: if it doesn't get drunk at the bottom, it means that there is enough oxygen to breathe in the mine).

Sanation of the well is a comprehensive procedure that consists of several stages. To begin with, throw back all the water from the well using the powerful pumping equipment. Then carefully clean the walls of the shaft from mucus and plaque (use the metal brush with a soft bristle and rough sponge). In parallel, in the course of cleaning, we close the resulting cracks in the seams or rings with a special composition (mix cement and liquid glass in equal proportions). If necessary, install steel staple locks, which will prevent the displacement of the rings.

The next stage is the capital cleaning of the bottom of the well from garbage, sandy and or or blind sediments and replacement of the bottom filter. Traditionally, flimine river gravel with a fraction of 40-100 mm is used as a filter. The optimal thickness of the drainage layer is not less than 100 mm. Over the gravel, it is possible to lay a layer of zeolite or shungitis - these natural sorbents provide excellent filtering and significantly improve the taste quality of water.

After replacing the bottom filter, proceed to disinfection of water in the mine. For this wall, the well thoroughly treat with a disinfecting solution (inject 15-20 g of chlorine lime in a liter). The remaining solution is pouring on the bottom of the mine. Next, cover the well with a tarralet or polyethylene film and close the lid tightly. In order not to choose volatile connections, work in a respiratory mask. After 48 hours, twice spend the full water pumping, however, remember that it is possible to fully use the well only a month after the chlorination procedure (before using well water for drinking and cooking, hand out samples of purified water in the SES to confirm compliance with sanitary requirements).

If the well water does not correspond to sanitary standards, even after a comprehensive mine rehanging, it is necessary to apply disinfective dosage chucks - ceramic cylinders filled with chlorine lime and calcium hypochlorite. It is advisable to entrust the installation and replacement of this equipment, which accurately calculate the disinfectant dosage.
7
Eliminate the cause of the darkening of the well water associated with the low flow of this resource, only by increasing its consumption. If the water is muttered due to improper operation of the pumping equipment, it is necessary to reinstall the device according to the manufacturer's instructions.
Water purification in the well - the task is not easy, but perfect. Following our instructions, any caring owner will be able to return well water with crystal purity.
