The geological report certifies very good water quality approximately 90 to 100 meters deep. Unfortunately the first two deep drilling holes collapsed after a few weeks.
This caused lively discussions about the way forward. After considering various aspects drilling started again at another site, this time with heavy equipment and a different technical method.
The new site chosen is next to the school building.
Indeed the depth of 100 metres was reached after a very short time.
Next thing the technical connections were made and pumps and pressure vessel installed.
