In some regions, the issue of water supply is acute. If this issue is not resolved by the authorities, you have to independently look for sources of water supply for your household. The easiest way is to use open reservoirs (rivers, lakes), springs. But if these sources are far from home, you can solve the problem in a completely unusual way.

Initially, such a decision may cause doubts in you. But having understood the principle of operation of such technology, it will be clear that this is a very real proposal.

A bit of theory. It is known that water vapor is suspended in the air, this phenomenon is called air humidity. Often we observe such a phenomenon as fog, dew, the formation of water droplets on cold objects (something removed from the refrigerator). This is the result of the manifestation of such a definition as the "dew point", at which moisture at a certain temperature, which is in the air, becomes unable to be in a gaseous state and settles on the surface of bodies. This is the phenomenon we use.

Where can we get temperatures below the dew point on a hot summer day? The answer is simple - underground! At a depth of up to 2 meters, the soil temperature changes slightly during the day, but not significantly, and this temperature is much lower than the air temperature. And at a depth of up to 8 meters, the temperature of the soil changes only with the change of seasons. If you drive air to this depth, then it will cool down from the cold walls of the well. If it cools below the dew point, then the moisture present in the air will begin to settle on the surface of the pipe. In the end, the droplets will fall to the lowest point and collect there in the drive.

This is the water we will be using. It remains only to pump it out with a pump.

Two schemes are offered.

The first is a well according to the scheme in the figure.

The depth of the well - the more, the better. It is possible that you will come across a “perch water” with this well - this is groundwater that lies close to the surface of the earth. The quality of these waters is not very good because they are prone to pollution. The optimal depth of the well is from 3 to 10 m. A pipe is lowered into the well, through which air is supplied. The end of the pipe should be 30-50 cm above the bottom of the well, water will be collected in this space, which can be pumped out with a pump.

This installation will be able to produce water only when the air temperature at the bottom of the well drops below the dew point. You can check this possibility in the following way: measure the air temperature at the bottom of the well with a thermometer lowered on a rope. You also need to find out the humidity in the street - either with a psychrometer (the most accurate data), or look on the Internet for the data of the weather station closest to you. From the dew point table, determine the possibility of condensation. It is necessary that, with the available air humidity, the temperature at the bottom of the well be below the dew point.

Second installation option:
