Abstract: Sinking wells belong to underground facilities. Large-diameter sinking wells are often constructed as retention basins and reservoirs for wastewater treatment plants, which is determined by the Urban Wastewater Treatment Directive. The directive obliges Member States to implement the principles of sustainable development, promoting sustainable sewage collection and treatment systems. When designing and constructing facilities using sinking well technology, contact between the structure and the ground must be considered. During the lowering of a sinking well into the ground medium, a number of negative impacts may occur and affect the sinking process, including excessive ground settlement outside the well, damage or destruction of adjacent objects, tilt of the well casing from the vertical, and uncontrolled sinking of the well casing. The aim of this paper is to determine the occurrence of negative impacts during the lowering of sinking wells. Determining the incidence of negative impacts could help to avoid pre-failure and emergency situations relating to sinking wells. A fuzzy TOPSIS method was used to determine the above.
