Abstract
The study presents the research results of water consumption in relation to the daily volume of wastewater, including the so-called non-returnable volume, in a household that reuses treated wastewater. The research was conducted in 2023-2024 in a household – the forester’s lodge of the Poleski National Park (PNP), from which wastewater is discharged to a hybrid constructed wetland wastewater treatment plant with a closed water circuit. The forester’s lodge is located in Kulczyn in the Włodawa district. The forester’s lodge is inhabited by a family of 4. The plot is supplied with water from the communal water supply network. Based on the obtained test results, the amount of water consumed in the household was determined, including the amount of the reused treated wastewater and the volume of sewage irreversibly lost in relation to the total amount of water consumption in the household, throughout the year and in different seasons. The analysis of water consumption showed that in 2023, the inhabitants used 155.498 m3 of water, including 27.501 m3 of the reused treated wastewater (the average daily water consumption per person was 106.5 dm3∙M–1∙d–1). In 2024, the inhabitants used 140.250 m3 of water, including 25.780 m3 of the reused treated wastewater (the average daily water consumption per person was 96.1 dm3∙M–1∙d–1). It was shown that in the analyzed period, the volume of irretrievably lost wastewater accounted for 7.29% (in 2023) and 6.69% (in 2024) of the total amount of water used in the household (tap water together with the reused treated wastewater).
