Artesian groundwater was discovered in central and eastern inland Australia around 1880. Further extensive geological investigations and water-well information helped to outline the shape and size of a large confined groundwater system, now known as the Great Artesian Basin (GAB). The GAB extends across four Australian states underlying 22% of the Australian continent. Temperatures of the artesian groundwater (which is generally of a very good quality) range from 30o to 100o C at the well heads. As the groundwater is too hot for town water supply and for stock to drink, it needs to be cooled down before consumption. That is why cooling towers can be seen throughout the region. Some cooling towers are equipped with electric fans, in which the case electric power is spent to remove the thermal energy of the groundwater
