The beginning of the story is here. Finally, Danila and me were inside the sewer! As expected, the brook flowed by the central ditch, and there were sufficient "walkways" at the left and at the right. Moreover, at a meter from the outlet the big pipe was sticking off from the wall and the brook flows from it, and upper the ditch was dry. In a short time we had walked to the hall, resembling one from the third part of Chemnitz chronicles. But there were also differences. First, the dry sewer continued after the hall, going ahead in the darkness (pic 1). And there was also the secon tube, perpendiculat to that, by which we were going, made of brick. A small brook flows by that second sewer (pic 2, 3).
I didn't pay any attention to the stream in the perpendicular sewer. Exploring Plei&ss;enbach, I was walking by a sewer with much stronger stream without a problem. The only inconvenience was due to the necessity to wet out feet, since we didn't have waterproof boots. So I made a wide step into the stream, having intention to overcome it quiclky.
Then the events were developing not as expected. The bottom was wery slippery, so I had fallen. I tried to stand up, but was not able to do it because of the fact, that the water stream indeed appeared to be quite strong and dragged me from the hall into the dark sewer. In addition the protective helmet with a flashlight had falled off from my head (thanks to bad Chinese liner, which were weakening all the time) and had quickly disappeared behind the sewer turn. Later I had realized that the sewer probably had notable (but not recognizable by eye) slope.
Finally I had managed to seize upon something at the bottom, stop my motion and stand up. Like Atlas I set my arms and head against the sewer dome and only that way I could slowly move myself against the flow, which all the time was tending to knock me down (pic 4). It seemed to me, that I overpassed some meters of distance to the hall for half an hour. Then Daniel helped me to get out from the sewer flume, I danced a bit for joy (pic 5), and we had left the sewer and went home.
But actually we could avoid all this thriller, if we paid more attention even to the small water stream. Yes, under the ground any amount of water may be dangerous and must not be ignored.
