The well -structure of the well is a relatively inexpensive and rather practical way of water production, unless you need crystal clean water.
Do not dig a well in the place where the level of groundwater is close to the surface or even comes to the surface, since this water is usually polluted by external factors and is not filtered. And through the cracks between the rings of the well, it easily gets into the well and pollute water, which will become unsuitable for drinking and it can only be used for technical needs. But if you successfully choose a place, then you will have a great source with clean water for drinking.
