Abstract—Pollution caused by the discharge of wastewater into the Lepenc river basin is diverse and directly affects the quality of life of the inhabitants of this area. This paper aims to investigate the physicochemical characteristics of pollution from wastewater discharges, build the water balance of the entire basin, and identify the risk to human life due to lack of drinking water. From the hydrological point of view, the Lepenc river basin is divided into sub-basins, and the results obtained by experimental measurements show that wastewater pollution varies from one sub-basin to another and depends on the amount and origin of wastewater. Combined analysis of the available amount of water and the need for clean water, which is based on parameters that are out of the water balance below the water stress limit, the need for wastewater treatment is a necessity and that continuous water discharge of contaminants in the water basin is unacceptable or in other words very dangerous. The results showed that some analyzed parameters are outside the acceptable limits for drinking water such as TSS with values above 75 mg/L, BOD₅ with values up to 9.42 mg/L, NH⁺₄ up to 9.48 mg/L, and PO^3-₄ up to 1.76 mg/L. On the other hand, the waters of the Lepenci river basin had low heavy metal pollution during the observed period. Therefore, routine monitoring of wastewater in the Lepenc Basin is recommended to prevent the risk of pollution of the basin,
