The summer cottage without water is simply unthinkable, but many dacms are often faced 
with a problem: no central water supply. And here it is necessary to think and guess - where and how to produce water. Many build wells. Yes, this work is very time-consuming, but it pays for yourself with interest. And in winter and summer with the help of the pump, you can deliver water and in the country house, and to the greenhouse. But many daches prefer the well. Naturally, the process of drilling wells is not as simple as it seems at first glance. Any well, which is drilled without complying with the required measures, can easily lead to a complete dehydration of the aquatic wells of neighbors, and even to the death of the entire settlement. The geological state of the soil is everywhere different, and therefore water is locked at the depths of various.
Drilling wells for water It is made in one of the following methods:
- hydrodynamic
- shock-cable
- Shnekov
- rotational
More than 85% of the main volume of drilling, the wells are carried out by a rotational method with washing with clay solution or technical water. The speed of drilling by this method in the rocks of the middle and soft hardings at different depths about 3 times higher than to compare with the shock-channel method. It is also much easier and the design of the well for rotational drilling, and the use of casing by 40-65% less than when shock-rope drilling method.
Drive drilling method used when drilling wells in areas where geology has not been studied sufficiently, where it is necessary to open the aquifer horizons. In those places where it is difficult to wash the wells to organize, or well the depth can be no more than 100-150 m, as well as the drilling method of drum-rope applies to drilling a long diameter well (up to 900 mm).
Screw well drilling used in loose, soft rocks a depth of 50-80 m or more, with a diameter of 60-400 mm. This drilling unit works on the principle: particles of rocks that are torn off by rotating bit from a slaughter, fall on the surface of the screw auke column. And then they are under the action of centrifugal forces, cress down to the well walls, constantly on the blades of the screw column rose and fall apart on the surface through the wellness of the well.
The hydrodynamic method is used to open the aquifers, which are composed of non-cemented sands. Using this method, destruction I. removing breeds from a slaughter is made under the action of a strong jet of water. This jet output with a huge speed through the holes in the hydraulic nozzle filter pipe.
To achieve on your summer cottage, normal quality water that would correspond to GOST "Drinking water", wells preferably equip water filters. They will get rid of your drinking water from excess salts, iron, stiffness and other harmful and unnecessary impurities.
