Hello everyone. I live in a mountain area, a long and narrow plot with a slight slope. This year, water problems started. Until now, I used water from a dug well distant from the house about 1 km, the water flowed under its own pressure. There is no chance of a water supply in the area and a decision was made to drill a deep well. I was looking for a company that has a small crawler drilling rig because the plot is narrow and built-up and not all equipment will enter. I found a drilling company and thought they would send some dowser to look for somewhere to drill beforehand, but the owner only asked for a plot number and said they only rely on hydrogeological maps. After checking, it turned out that on my plot there should be water everywhere. Drilling was performed using the hammer method. The first borehole is 46 m, at the beginning to about 10 meters clay and loam, and then slate. Water appeared at the beginning of drilling and then it was dry until the very end. A second borehole was made, approx. 40 m away from the first one. The situation was similar, at the beginning clay and loam, and then up to 46 m of slate and no water drop. Desperate, I thought to dig a vertebral well at the site of the first bore, where some water appeared at the beginning of drilling. I called the dowser to the plot to mark the place for digging. After checking, the guy marked a few points distant from the first bore, about 10 and 15 m and found that there was water in these places and at a depth smaller than the bore was made. Gentlemen, what to think about it, is it possible.
