The article assesses the physical and chemical parameters of drinking water before and after the modernization of the technological system of water treatment station in Drzenin, Poland. The extension and modernization of the existing installation was necessary due to the poor technical condition of the devices, increasing demand for water in recent years and the periodic exceeding of the permissible values of water quality indicators. Analysis of physical and chemical properties of drinking water after the modernization of the system showed the effectiveness of the water purification processes used and the correct selection of the technological line. The obtained water quality parameters were in accordance with the Regulation of the Minister of Health on the quality of water intended for human consumption (Journal of Laws of 2017, item 2294).
