Water is one of life's and nature's most dominant elements, with its presence influencing and controlling the climatic, geological, and biological conditions of an area. Continuous monitoring of subterranean water with the aim of its optimal management has become necessary nowadays. The aspiration of this research is, that the development of “smart” methods for this purpose, will lead to the optimization of the quality of life of the inhabitants of a region, always respecting the environment. The use of geoinformatics methods can contribute to the development of models according to which a network for the logging and control of boreholes and subterranean water will be created, which in turn will lead to smart and direct decision-making concerning their management. In this research, an effort is made to show the contribution of spatial analysis to the design and management of the subterranean water of an area, with the vision of a smart city being the ultimate goal.
