A sustainable option for the supply of dry regions
In regions with a dry (arid) or mainly dry (semi-arid) climate the production of drinking water is an existential problem. On average, more water evaporates here than is compensated as a result of precipitation. The ground is therefore dried out and the generally salty groundwater is often only found at great depths. Additionally, in many cases the groundwater level is steadily dropping or so-called fossil, non-renewable aquifers are used. A sustainable production of drinking water from groundwater that can also be used for future generations is thus not possible. The use of surface waters is also difficult in these regions, especially at a great distance from the sea.
