Industrial activity has a direct impact on the environment. Such example is the influence of groundwater well on the hydrogeological conditions. The aim of this paper is description of multi­criteria evaluation of different variants of underground well location. Water from the proposed well will supply sewage treatment plants in Częstochowa, for technological purposes. For the design of appropriate water well­analytical calculations were conducted, among others; radius and depth of the depression cone, isochromatic lines­25 years and guidelines for the design of the well. Subsequently charts of groundwater surface during the interaction with the well were made. The result of the above mentioned calculations was to determine the size of the depression cone for approx. 4 m with depth of 0.32 m. An important result was the selection of theoption to build two groundwater wells in the immediate vicinity of the target buildings to provide water. Performed analysis confirms the possibility of using multi­criteria analysis in the process of making quick and optimal decisions for large areas where there are many factors affecting the performance of a groundwater well.
