Crystal clear water gushes from our well at the school
Email from Peru 2 p.m. CET: The well drilling was stopped at a depth of 71,40 m due to extremely hard solid rock. The installation of the pipework went smoothly. At 8 p.m. last night a provisional pump started swilling the well. An hour later the water was “as clean as possible” so that the filter gravel could be built into the aquiferous layers. Our own measurements showed that 6,000 litres of water could be pumped in an hour.
Today the pump is going to be installed 5,00 metres lower, as last night everything had to be done very quickly. The solid rock has made the drill completely useless. Perhaps will be able to exhibit the drill in the school at some point in the future. Best regards, Oebele + Udo.
Email from Peru 6:06 p.m. CET: Crystal clear water is now gushing at a rate of 150 litres/min = 9,000 litres/hour and is tasteless. Greetings, Udo.
Email from Peru 8:19 p.m. CET: I attach two pictures of the drilling head. The diamonds are totally spent and parts of them are broken away. Normally they can drill between 500 and 600 metres; in Curahuasi they only managed 70 m. We were told they were new! It is impossible to put the diamonds back into the drilling head. Greetings, Udo
