It is relatively unknown that the volume of fresh water stored underground on our planet is 20 times greater than the overall volume of surface fresh water flowing in rivers and lakes. Groundwater is therefore potentially the main primary source of water supply on the planet. Indeed, nowadays around 40% of worldwide supply comes from groundwater, extracted from aquifers using wells (in some regions, such as the US, its relative weight amounts to over 50% of the supply).

Access to water is becoming an increasing challenge due to population growth, a population of 10 billion people being expected by 2050. The urbanization process, the increase in food demand, pollution and climate change are also key factors. They all accentuate the imbalance in water distribution and intensifies water scarcity predictions.
