Located at 3,000m above sea level in the Atacama Desert of northern Chile, the mining and hydrometallurgical operation of this mine is 4km away from the mine and smelter. In the beginning of the mining operations, the initial target capacity was 150,000t/y of copper cathodes but optimization during construction raised the rating to 180,000t/y by the commissioning date. Traditionally, piezometers around the pit have been monitored by isolated standalone dataloggers which store information on an internal memory. Data was collected manually every month. The mining operator wanted to automatize and increase the hydrogeological control with more data and additional well points on the new and deepest open pit levels. With more than 60 wells in a huge area of 7.5miles by 3miles, the challenge of doing it wirelessly was enormous.
