ABSTRACT
Increased efficiency of wastewater treatment highlights the role of combined sewer overflows in deterioration the quality of water receiver because pollutant loads discharged by them have a growing share in entire load discharged into a receiver. The article contains the results of the wastewater quality analyzes emitted into the receiver from the three studied combined sewer overflows of the city of Lodz. The results demonstrated a large variations in the pollutant concentration directed to the receiver during rain events. The possible impact of untreated wastewater emitted to the receiver is also presented. Apart from the pollution of the receiver, mainly by organic and nutrient substances, the microbiological contamination which is dangerous for people using the river as a recreation area and for animals that use a water receiver as a source of drinking water, should be taken into particular attention.
