First, research is carried out to understand in which area it is more appropriate to dig to find an underground water table. Once identified, a deep excavation is made and pipes connected to a pumping system are inserted. These pipes are put into action twice a day: they pump the water into a cistern located at a height of 10 meters which mainly performs two functions: the first is to purify the water taken from the groundwater. The other function is to pump water to the surrounding villages through a system of pipes that starts from the cistern itself and reaches not only the individual homes of the surrounding villages, but also public buildings, for a total radius of about 10 square kilometers. .
