The well

To ensure water autonomy of the position, Germans drilled a well, several meters deep.
The water was brought up with the aid of a pump located in a room that was not in the axis of the entrance, and this was all protected by a thick layer of concrete (80 cm).

However, in the months following the installation of the pump system, the samples taken showed that the extracted water was not drinkable and the well was finally never used.
